Control of Emissions From New Marine
Compression-Ignition Engines at or
Above 30 Liters per Cylinder
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
AGENCY: Environmental Protection
Agency (EPA).
ACTION: Proposed Rule.
SUMMARY: EPA is proposing emission
standards for new marine diesel engines
with per cylinder displacement at or
above 30 liters (called Category 3 marine
diesel engines) installed on U.S. vessels,
under section 213 of the Clean Air Act
(CAA or ‘‘the Act’’). The proposed
engine standards are equivalent to the
nitrogen oxides (NOX) limits recently
adopted in the amendments to Annex VI
to the International Convention for the
Prevention of Pollution from Ships
(MARPOL Annex VI) and are based on
the position advanced by the United
States Government as part of those
international negotiations. The nearterm standards for newly-built engines
would apply beginning in 2011. Longterm standards would begin in 2016 and
are based on the application of highefficiency aftertreatment technology. We
are also proposing a change to our diesel
fuel program that would forbid the
production and sale of marine fuel oil
above 1,000 ppm sulfur for use in the
waters within the proposed U.S. ECA
and internal U.S. waters and allow for
the production and sale of 1,000 ppm
sulfur fuel for use in Category 3 marine
vessels.
This proposal is part of a coordinated
strategy to ensure that all ships that
affect U.S. air quality meet stringent
NOX and fuel sulfur requirements. In
addition, on March 27, 2009, the U.S.
Government forwarded a proposal to the
International Maritime Organization
(IMO) to amend MARPOL Annex VI to
designate an Emission Control Area
(ECA) off U.S. coasts. If this proposed
amendment is not timely adopted by
IMO, we intend to take supplemental
action to control emissions from vessels
affecting U.S. air quality.
We project that in 2030 this
coordinated strategy would reduce
annual emissions of NOX and
particulate matter (PM) from oceangoing vessels by 1.2 million and 143,000
tons, respectively. These reductions are
estimated to annually prevent between
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
13,000 and 32,000 PM-related
premature deaths, between 220 and 980
ozone-related premature deaths,
1,500,000 work days lost, and
10,000,000 minor restricted-activity
days. The estimated annual monetized
health benefits of this coordinated
strategy in 2030 would be between $110
and $280 billion, assuming a 3 percent
discount rate (or between $100 and $260
billion assuming a 7 percent discount
rate). The annual costs would be
significantly less, at approximately $3.1
billion.
The proposed regulations also include
technical amendments to our motor
vehicle and nonroad engine regulations.
Many of these changes involve minor
adjustments or corrections to our
recently finalized rule for new nonroad
spark-ignition engines, or adjustment to
other regulatory provisions to align with
this recent final rule.

I. Overview
This proposal is part of a coordinated
strategy to address emissions from
ocean-going vessels and is an important
step in EPA’s ongoing National Clean
Diesel Campaign (NCDC). In recent
years, we have adopted major new
programs designed to reduce emissions
from new diesel engines, including
those used in highway (66 FR 5001,
January 18, 2001), nonroad (69 FR
38957, June 29, 2004), locomotive, and
marine applications (73 FR 25098, May
6, 2008). When fully phased in, these
programs will significantly reduce
emissions of harmful regulated
pollutants from these categories of
engines and vehicles. This Notice of
Proposed Rulemaking (NPRM) sets out
the next step in this ambitious effort by
addressing emissions from the largest
marine diesel engines, called Category 3
(C3) marine diesel engines. These are
engines with per cylinder displacement
at or above 30 liters per cylinder, which
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
are used primarily for propulsion power
on ocean-going vessels (OGV).
Emissions from OGV remain at high
levels. The Category 3 engines on these
vessels use emission control technology
that is comparable to that used by
nonroad engines in the early 1990s, and
use fuel that can have a sulfur content
of 30,000 ppm or more. As a result,
these engines emit high levels of
pollutants that contribute to unhealthy
air in many areas of the U.S. Nationally,
in 2009, emissions from Category 3
engines account for about 10 percent of
mobile source nitrogen oxides (NOX)
emissions, about 24 percent of mobile
source diesel PM2.5 emissions (with
PM2.5 referring to particles with a
nominal mean aerodynamic diameter
less than or equal to 2.5 μm), and about
80 percent of mobile source sulfur
oxides (SOX) emissions. As we look into
the future, however, emissions from
ocean-going vessels are expected to
become a dominant inventory source.
This will be due to both emission
reductions from other mobile sources as
new emission controls go into effect and
to the anticipated activity growth for
ocean transportation. Without new
controls, we anticipate the contribution
of ocean-going vessels to national
emission inventories to increase to
about 24 percent, 34 percent, and 93
percent of mobile source NOX, PM2.5,
and SOX emissions, respectively in
2020, growing to 40 percent, 48 percent,
and 95 percent respectively in 2030.
The coordinated emission control
strategy will lead to significant
reductions in these emissions and
important benefits to public health.
The evolution of EPA’s strategy to
control mobile source diesel emissions
has followed a technology progression,
beginning with the application of highefficiency advanced aftertreatment
approaches and low sulfur fuel
requirements first to highway vehicles,
then to nonroad engines and equipment,
followed by locomotives and smaller
marine diesel engines. The benefits of
this approach include maximizing air
quality benefits by focusing on the
largest populations of sources with the
shortest service lives, allowing engine
manufacturers to spread initial research
and development costs over a larger
population of engines, and allowing
manufacturers to address the challenges
of applying advanced emission controls
on smaller engines.
EPA has been working with engine
manufacturers and other industry
stakeholders for many years to identify
and resolve challenges associated with
applying advanced diesel engine
technology to Category 3 engines to
achieve significant NOX emission

reductions. This work was fundamental
in developing the emission limits for
Category 3 engines that we are
proposing in this action and informed
the position advocated by the United
States in the international negotiations
for more stringent tiers of international
engine emission limits.
Our coordinated strategy to control
emissions from ocean-going vessels
consists of actions at both the national
and international levels. It includes: (1)
The engine and fuel controls we are
proposing in this action under our Clean
Air Act authority; (2) the proposal 1
submitted by the United States
Government (USG) to the International
Maritime Organization (IMO) to amend
Annex VI of the International
Convention for the Prevention of
Pollution from Ships (MARPOL Annex
VI) to designate U.S. coasts as an
Emission Control Area (ECA) 2 in which
all vessels, regardless of flag, would be
required to meet the most stringent
engine and marine fuel sulfur
requirements in Annex VI; and (3) the
new engine emission and fuel sulfur
limits contained in the amendments to
Annex VI that are applicable to all
vessels regardless of flag and that are
implemented in the U.S. through the
Act to Prevent Pollution from Ships
(APPS).
The amendments to APPS to
incorporate Annex VI provide the
authority to ensure compliance with
MARPOL Annex VI by U.S. and foreign
vessels that enter U.S. ports or operate
in U.S. waters. In light of this, we are
deciding not to revisit our existing
approach with respect to foreign vessels
in this rule. However, the MARPOL
Annex VI Tier III NOX and stringent fuel
sulfur limits are geographically based
and would not become effective absent
designation of U.S. coasts as an ECA. As
noted above, the United States
forwarded a proposal to IMO to amend
Annex VI to designate U.S. coasts as an
ECA. If this amendment is not adopted
in a timely manner by IMO, we intend
to take supplemental action to control
emissions from vessels that affect U.S.
air quality.
Our coordinated strategy for oceangoing vessels would significantly reduce
emissions from foreign and domestic

vessels that affect U.S. air quality, and
the impacts on human health and
welfare would be substantial. We
project that by 2030 this program would
reduce annual emissions of NOX and
particulate matter (PM) by 1.2 million
and 143,000 tons, respectively, and the
magnitude of these reductions would
continue to grow well beyond 2030.3
These reductions are estimated to
annually prevent between 13,000 and
32,000 PM-related premature deaths,
between 220 and 980 ozone-related
premature deaths, 1,500,000 work days
lost, and 10,000,000 minor restrictedactivity days. The estimated annual
monetized health benefits of this
coordinated strategy in 2030 would be
between $110 and $280 billion,
assuming a 3 percent discount rate (or
between $100 and $260 billion
assuming a 7 percent discount rate). The
annual cost of the overall program in
2030 would be significantly less, at
approximately $3.1 billion.
A. What Are the Elements of EPA’s
Coordinated Strategy for Ocean-Going
Vessels?
Our coordinated strategy for oceangoing vessels, including the CAA
emission standard proposed in this
action, continues EPA’s program to
progressively apply advanced
aftertreatment emission control
standards to diesel engines and reflects
the evolution of this technology from
the largest inventory source (highway
engines), to land-based nonroad
engines, to locomotives and marine
diesel engines up to 30 liters per
cylinder. The results of these forerunner
programs are dramatic reductions in
NOX and PM2.5 emissions on the order
of 80 to 90 percent, which will lead to
significant improvements in national air
quality.
The combination of controls in the
coordinated strategy for ocean-going
vessels is expected to provide
significant reductions in PM2.5, NOX,
SOX, and toxic compounds, both in the
near term (as early as 2011) and in the
long term. These reductions would be
achieved in a manner that: (1) Is very
cost effective compared to additional
controls on portside vehicles and
equipment and other land-based mobile
sources that are already subject to
stringent technology-forcing emission
3 These emission inventory reductions include
reductions from ships operating within the 24
nautical mile regulatory zone off the California
Coastline, beginning with the effective date of the
Coordinated Strategy program elements. The
California regulation contains a provision that
would sunset the requirements of the rule if the
Federal program achieves equivalent emission
reductions. See https://www.arb.ca.gov/regact/2008/

standards; (2) leverages the international
program adopted by IMO to ensure that
all ships that operate in areas that affect
U.S. air quality are required to use
stringent emission control technology;
and (3) provides the lead time needed
to deal with the engineering design
workload that is involved in applying
advanced high-efficiency aftertreatment
technology to these very large engines.
Overall, the coordinated strategy
constitutes a comprehensive program
that addresses the problems caused by
ocean-going vessel emissions from both
a near-term and long-term perspective.
It does this while providing for an
orderly and cost-effective
implementation schedule for the vessel
owners and manufacturers, and in a way
that is consistent with the international
requirements for these vessels.
The human health and welfare
impacts of emissions from ocean-going
vessels, along with estimates of their
contribution to national emission
inventories, are described in Section II.
The proposed new tiers of Clean Air Act
engine emission standards to address
these emissions, and our justifications
for them, are discussed in Section III.
Section IV contains proposed changes to
our existing marine diesel fuel program.
In Section V, we describe a key
component of the coordinated strategy:
the recently-submitted proposal to
amend MARPOL Annex VI to designate
U.S. coasts as an ECA, as well as the
IMO approval process.
In addition to the new emission
limits, we are proposing several
revisions to our Clean Air Act testing,
certification, and compliance provisions
to better ensure emissions control in
use. We are also proposing several
regulations for the purpose of
implementing MARPOL Annex VI
pursuant to the Act to Prevent Pollution
From Ships (33 USC 1901 et seq.). These
revisions are described in Section VI.
Sections VII and VIII present the
estimated costs and benefits of our
coordinated program to address OGV
emissions, and Section IX presents the
analysis of programmatic alternatives
and a discussion of a potential
Voluntary Marine Verification Program.
(1) What CAA Standards Is EPA
Proposing?
We are proposing new tiers of
Category 3 marine diesel engine
standards under our Clean Air Act
authority, as well as certain revisions to
our marine fuel program.
Category 3 Engine Standards. Our
current standards for Category 3 engines
were adopted in 2003. These Tier 1
standards are equivalent to the first tier
of MARPOL Annex VI NOX limits and
PO 00000
Frm 00005
Fmt 4701
Sfmt 4702
44445
require the use of control technology
comparable to that used by nonroad
engines in the early 1990s. We did not
adopt PM standards at that time because
the vast majority of PM emissions from
Category 3 engines are the result of the
sulfur content of the residual fuel they
use and because of measurement
issues.4 The combination of the engine
and fuel standards we are proposing in
this NPRM and the USG proposal for
ECA designation will require all vessels
that operate in coastal areas that affect
U.S. air quality to meet advanced engine
standards and fuel controls.
We are proposing to revise our CAA
engine program to include two
additional tiers of NOX standards for
new marine diesel engines with per
cylinder displacement at or above 30
liters (Category 3 engines) installed on
vessels flagged or registered in the
United States. The proposed near-term
Tier 2 standards would apply beginning
in 2011 and would require more
efficient use of engine technologies
being used today, including engine
timing, engine cooling, and advanced
computer controls. The proposed longterm Tier 3 standards would apply
beginning in 2016 and would require
the use of high-efficiency aftertreatment
technology such as selective catalytic
reduction.
Because much of the operation of U.S.
vessels occurs in areas that would have
little, if any, impact on U.S. air quality,
we are proposing that our Clean Air Act
program allow the use of alternative
emission control devices (AECDs) that
would permit a ship to meet less
stringent requirements on the open sea.
The use of these devices would be
subject to certain restrictions, including
a requirement that the AECD not disable
emission controls while operating in
areas where emissions could reasonably
be expected to adversely affect U.S. air
quality, and that the engine is equipped
with a NOX emission monitoring device.
In addition, the engine would be
required to meet the Tier 2 NOX limits
when the AECD is implemented, and an
AECD would not be allowed on any Tier
2 or earlier engine.
In addition to the NOX emission
limits, we are proposing standards for
emissions of hydrocarbons (HC) and
carbon monoxides (CO) from new
Category 3 engines. As explained in
4 As explained in the NPRM, there were no
acceptable procedures for measuring PM from
Category 3 marine engines. Specifically, established
PM test methods showed unacceptable variability
when sulfur levels exceed 0.8 weight percent,
which was common at that time for both residual
and distillate marine fuels for Category 3 engines,
and no PM test method or calculation methodology
had been developed to correct that variability for
these engines. See 67 FR 37569, May 29, 2002.

Section III.B.1, below, we are not
proposing to set a standard for PM
emissions for Category 3 engines.
However, significant PM emissions
benefits will be achieved through the
ECA fuel sulfur requirements that will
apply to ships that operate in areas that
affect U.S. air quality. We are also
proposing to require engine
manufacturers to measure and report
PM emissions pursuant to our authority
in section 208 of the Act.
Fuel Sulfur Limits. EPA is in this
notice proposing fuel sulfur limits
under section 211(c) of the Clean Air
Act that match the limits that apply
under Annex VI in ECAs. First, we are
proposing to forbid the production and
sale of fuel oil with a sulfur content
above 1,000 ppm for use in the waters
within the proposed ECA (as well as
internal U.S. waters). Second, we are
proposing a revision to our existing
diesel fuel program to allow for the
production and sale of 1,000 ppm sulfur
fuel for use in Category 3 marine
vessels. This would allow production
and distribution of fuel consistent with
the new sulfur limits that will become
applicable, under Annex VI, in ECAs
beginning in 2015. Our current diesel
fuel program sets a sulfur limit of 15
ppm that will be fully phased-in by
December 1, 2014 for nonroad,
locomotive, and marine (NRLM) diesel
fuel produced for distribution/sale and
use in the U.S. Without this proposed
change to our existing diesel fuel
regulations, fuel with a sulfur content of
up to 1,000 ppm could be used in C3
marine vessels, but it could not be
legally produced in the U.S. after June
1, 2014.
(2) What is the United States
Government Proposal for Designation of
an Emission Control Area?
MARPOL Annex VI contains the
international standards for air emissions
from ships, including NOX and SOX
/PM emissions. The Annex VI NOX and
SOX /PM limits are set out in Table I–
1. Annex VI was originally adopted by
the Parties in 1997 but did not go into
force until 2005, after it was ratified by
fifteen countries representing at least 50
percent of the world’s merchant
shipping tonnage. The initial program
consisted of engine NOX emission
standards and fuel sulfur limits. The
NOX standards apply to all engines
above 130 kW installed on a ship
constructed on or after January 1, 2000
and were intended to reduce NOX
emissions by about 30 percent from
uncontrolled. There were two fuel
sulfur limits: A global limit of 45,000
ppm and a more stringent 15,000 ppm
limit that applies in SOX Emission
Control Areas (SECAs). This approach
ensured that the cleanest fuel was used
in areas that demonstrated a need for
additional SOX reductions, while
retaining the ability of ships to use
higher sulfur residual fuel on the open
ocean.
Annex VI was amended in October
2008, adding two tiers of NOX limits
(Tier II and Tier III) and two sets of fuel
sulfur standards.5 These amendments
will enter into force on July 1, 2010
unless an objection is raised before
January 1, 2010 by at least one-third of
the parties to the Annex or by parties
that represent at least 50 percent of the
world’s gross merchant tonnage. The
most stringent NOX and fuel sulfur
limits are regionally based and will
apply only in designated ECAs.

c Annex VI standards are in terms of percent sulfur. Global sulfur limits are 4.5%; 3.5%; 0.5%. ECA sulfur limits are 1.5%; 1.0%; 0.1%.
d Subject to a feasibility review in 2018; may be delayed to 2025.
To realize the benefits from the
MARPOL Annex VI Tier III NOX and
fuel sulfur controls, areas must be
designated as Emission Control Areas.
On March 27, 2009, the U.S. and
Canadian governments submitted a
proposal to amend MARPOL Annex VI
to designate North American coastal
waters as an ECA (referred to as the
‘‘U.S./Canada ECA’’ or the ‘‘North
American ECA’’).6 A description of this
submittal and the IMO approval process
is set out in Section V. ECA designation
would ensure that ships that affect U.S.
air quality meet stringent NOX and fuel
sulfur requirements while operating
within 200 nautical miles of U.S. coasts.
We expect the U.S./Canadian proposal
will be adopted by the Parties to
MARPOL Annex VI in March 2010. If,
however, the proposed amendment is
not adopted in a timely manner, we
intend to take supplemental action to
control harmful emissions from vessels
that affect U.S. air quality.

The United States became a party to
MARPOL Annex VI by depositing its
instrument of ratification with IMO on
October 8, 2008. This was preceded by
the President signing into law the
Maritime Pollution Prevention Act of
2008 (Pub. L. 110–280) on July 21, 2008,
that contains amendments to the Act to
Prevent Pollution from Ships (33 U.S.C.
1901 et seq.). These APPS amendments
require compliance with Annex VI by
all persons subject to the engine and

vessel requirements of Annex VI. The
amendments also authorize the United
States Coast Guard and EPA to enforce
the provisions of Annex VI against
domestic and foreign vessels and to
develop implementing regulations, as
necessary. In addition, APPS gives EPA
sole authority to certify engines
installed on U.S. vessels to the Annex
VI requirements. This NPRM contains
proposed regulations to implement
several aspects of the Annex VI engine
and fuel regulations, which we are
proposing under that APPS authority.
Our cost and benefit analyses for the
coordinated strategy includes the costs
for U.S. vessels of implementing those
provisions of the MARPOL Annex VI
program that are in addition to the ECA
requirements.
(4) Technical Amendments
The proposed regulations also include
technical amendments to our motor
vehicle and nonroad engine regulations.
Many of these changes involve minor
adjustments or corrections to our
recently finalized rule for new nonroad
spark-ignition engines, or adjustment to
other regulatory provisions to align with
this recent final rule.

(5) Summary
The coordinated strategy emission
control requirements are the MARPOL
Annex VI global Tier II NOX standards
included in the amendments to Annex
VI and the ECA Tier 3 NOX limits and
fuel sulfur limits that will apply when
the U.S. coasts are designated as an ECA
through an additional amendment to
Annex VI. The Annex VI requirements,
including the future ECA requirements,
will be enforceable for U.S. and foreign
vessels operating in the United States
waters through the Act to Prevent
Pollution from Ships.
We are also adopting the engine
controls for Category 3 engines on U.S.
vessels under our Clean Air Act
program, as required by Section 213 of
the Act.
Finally, we are proposing additional
requirements that are not part of the
Annex VI program or the ECA. These
are: Limits on hydrocarbon and carbon
monoxide emissions for Category 3
engines; PM measurement requirement,
to obtain data on PM emissions from
engines operating on distillate fuel; and
changes to our Clean Air Act diesel fuel
program to allow production and sale of
ECA-compliant fuel. We are also
considering changes to our emission
control program for smaller marine
diesel engines to harmonize with the
Annex VI NOX requirements, for U.S.
vessels that operate internationally.

B. Why is EPA Making This Proposal?
(1) OGV Contribute to Serious Air
Quality Problems
Ocean-going vessels subject to this
proposal generate significant emissions
of PM2.5, SOX, and NOX that contribute
to nonattainment of the National
Ambient Air Quality Standards
(NAAQS) for PM2.5 and ground-level
ozone (smog). NOX and SOX are both
precursors to secondary PM2.5
formation. Both PM2.5 and NOX
adversely affect human health. NOX is a
key precursor to ozone as well. NOX,
SOX and PM2.5 emissions from oceangoing vessels also cause harm to public
welfare, including contributing to
deposition of nitrogen and sulfur,
visibility impairment and other harmful
environmental impacts across the U.S.
The health and environmental effects
associated with these emissions are a
classic example of a negative externality
(an activity that imposes
uncompensated costs on others). With a
negative externality, an activity’s social
cost (the costs borne to society imposed
as a result of the activity taking place)
is not taken into account in the total
cost of producing goods and services. In
this case, as described in this section
below and in Section II, emissions from
ocean-going vessels impose public
health and environmental costs on
society, and these added costs to society
are not reflected in the costs of
providing the transportation services.
The market system itself cannot correct
this externality because firms in the
market are rewarded for minimizing
their production costs, including the
costs of pollution control. In addition,
firms that may take steps to use
equipment that reduces air pollution
may find themselves at a competitive
disadvantage compared to firms that do
not. To correct this market failure and
reduce the negative externality from
these emissions, we propose to set a cap
on the rate of emission production from
these sources. EPA’s coordinated
strategy for ocean-going vessels will
accomplish this since both domestic
and foreign ocean-going vessels will be
required to reduce their emissions to a
technologically feasible limit.
Emissions from ocean-going vessels
account for substantial portions of the
country’s ambient PM2.5, SOX and NOX
levels. We estimate that in 2009 these
engines account for about 80 percent of
mobile source sulfur dioxide (SO2)
emissions, 10 percent of mobile source
NOX emissions and about 24 percent of
mobile source diesel PM2.5 emissions.
Emissions from ocean-going vessels are
expected to dominate the mobile source
inventory in the future, due to both the
PO 00000
Frm 00007
Fmt 4701
Sfmt 4702
44447
expected emission reductions from
other mobile sources as a result of more
stringent emission controls and due to
growth in the demand for ocean
transportation services. By 2030, the
coordinated strategy would reduce
annual SO2 emissions from these diesel
engines by 1.3 million tons, annual NOX
emissions by 1.2 million tons, and PM2.5
emissions by 143,000 tons, and those
reductions would continue to grow
beyond 2030 as fleet turnover to the
clean engines continues. While a share
of these emissions occur at sea, our air
quality modeling results described in
Section II show they have a significant
impact on ambient air quality far inland.
Both ozone and PM2.5 are associated
with serious public health problems,
including premature mortality,
aggravation of respiratory and
cardiovascular disease (as indicated by
increased hospital admissions and
emergency room visits, school absences,
lost work days, and restricted activity
days), changes in lung function and
increased respiratory symptoms, altered
respiratory defense mechanisms, and
chronic bronchitis. Diesel exhaust is of
special public health concern, and since
2002 EPA has classified it as likely to be
carcinogenic to humans by inhalation at
environmental exposures. Recent
studies are showing that populations
living near large diesel emission sources
such as major roadways, rail yards, and
marine ports are likely to experience
greater diesel exhaust exposure levels
than the overall U.S. population, putting
them at greater health risks.7 8 9

screening-level analysis 10 of selected
marine port areas to better understand
the populations that are exposed to

10 This type of screening-level analysis is an
inexact tool and not appropriate for regulatory
decision-making; it is useful in beginning to
understand potential impacts and for illustrative
purposes. Additionally, the emissions inventories
used as inputs for the analyses are not official
estimates and likely underestimate overall
emissions because they are not inclusive of all
emission sources at the individual ports in the
sample.

these facilities.11 12 13 14 This screeninglevel analysis focused on a
representative selection of national
marine ports.15 Of the 45 marine ports
selected, the results indicate that at least
18 million people, including a
disproportionate number of low-income
households, African-Americans, and
Hispanics, live in the vicinity of these
facilities and are being exposed to
ambient diesel PM levels that are 2.0
μ g/m3 and 0.2 μ g/m3 above levels
found in areas further from these
facilities. Considering only ocean-going
marine engine diesel PM emissions, the
results indicate that 6.5 million people
are exposed to ambient diesel
particulate matter (DPM) levels that are
2.0 μg/m 3 and 0.2 μ g/m3 above levels
found in areas further from these
facilities. Because those populations
exposed to diesel PM emissions from
marine ports are more likely to be lowincome and minority residents, these
populations would benefit from the
controls being proposed in this action.
The detailed findings of this study are
available in the public docket for this
rulemaking.
Even outside port areas, millions of
Americans continue to live in areas that
do not meet existing air quality
standards today. With regard to PM2.5
nonattainment, in 2005 EPA designated
39 nonattainment areas for the 1997
PM2.5 NAAQS (70 FR 943, January 5,
2005). These areas are composed of 208
full or partial counties with a total

December 22, 2008, there are 58 2006
PM2.5 nonattainment areas composed of
211 full or partial counties. These
numbers do not include individuals
living in areas that may fail to maintain
or achieve the PM2.5 NAAQS in the
future. Currently, ozone concentrations
exceeding the 8-hour ozone NAAQS
occur over wide geographic areas,
including most of the nation’s major
population centers. As of December
2008, there are approximately 132
million people living in 57 areas (293
full or partial counties) designated as
not in attainment with the 8-hour ozone
NAAQS. These numbers do not include
people living in areas where there is a
potential that the area may fail to
maintain or achieve the 8-hour ozone
NAAQS.
In addition to public health impacts,
there are serious public welfare and
environmental impacts associated with
PM2.5 and ozone emissions. Specifically,
NOX and SOX emissions from diesel
engines contribute to the acidification,
nitrification, and eutrophication of
water bodies. NOX, SOX and direct
emissions of PM2.5 can contribute to the
substantial impairment of visibility in
many parts of the U.S. where people
live, work, and recreate, including
national parks, wilderness areas, and
mandatory class I Federal areas.16 The
deposition of airborne particles can also
reduce the aesthetic appeal of buildings
and culturally important articles
through soiling, and can contribute
directly (or in conjunction with other
pollutants) to structural damage by
means of corrosion or erosion. Finally,
ozone causes damage to vegetation
which leads to crop and forestry
economic losses, as well as harm to
national parks, wilderness areas, and
other natural systems.
While EPA has already adopted many
emission control programs that are
expected to reduce ambient PM2.5 and
ozone levels, including the Nonroad
Spark Ignition Engine rule (73 FR
59034, Oct. 8, 2008), the Locomotive
and Marine Diesel Engine Rule (73 FR
25098, May 6, 2008), the Clean Air

FR 5002, Jan. 18, 2001), and the Tier 2
Vehicle and Gasoline Sulfur Program
(65 FR 6698, Feb. 10, 2000), the
additional PM2.5, SOX and NOX
emission reductions resulting from the
coordinated approach described in this
action would assist states in attaining
and maintaining the PM2.5 and ozone
NAAQS near term and in the decades to
come.
Air quality modeling conducted by
EPA projects that in 2020 at least 13
counties with about 30 million people
may violate the 1997 standards for PM2.5
and 50 counties with about 50 million
people may violate the 2008 standards
for ozone. These numbers likely
underestimate the impacted population
since they do not include the people
who live in areas which do not meet the
2006 PM2.5 NAAQS. In addition, these
numbers do not include the additional
13 million people in 12 counties who
live in areas that have air quality
measurements within 10 percent of the
1997 PM2.5 NAAQS and the additional
80 million people in 135 counties who
live in areas that have air quality
measurements within 10% of the 2008
ozone NAAQS. The emission reductions
resulting from this coordinated strategy
would assist these and other states to
both attain and maintain the PM2.5 and
ozone NAAQS.
State and local governments are
working to protect the health of their
citizens and comply with requirements
of the Clean Air Act. As part of this
effort, they recognize the need to secure
additional major reductions in diesel
PM2.5, SOX and NOX emissions by
undertaking numerous state level
actions, while also seeking Agency
action, including the setting of the CAA
Category 3 engine standards being
proposed in this NPRM and the U.S.
proposal to IMO to amend Annex VI to
designate U.S. coastal areas as an ECA,
and related CAA certification and fuel
provisions to complement that ECA
proposal. EPA’s coordinated strategy to
reduce OGV emissions through engine
emission controls and fuel sulfur limits
would play a critical part in state efforts
to attain and maintain the NAAQS
through the next two decades.
In addition to regulatory programs,
the Agency has a number of innovative
programs that partner government,
industry, and local communities
together to help address challenging air
quality problems. Under the National
Clean Diesel Campaign, EPA promotes a
variety of emission reduction strategies
such as retrofitting, repairing, replacing
and repowering engines, reducing idling
and switching to cleaner fuels.
In 2008, Congress appropriated
funding for the Diesel Emissions

Reduction Program (DERA) under the
Energy Policy Act of 2005 (EPAct 2005)
to reduce emissions from heavy-duty
diesel engines in the existing fleet. The
EPAct 2005 directs EPA to break the
funding into two different components:
A National competition and a State
allocation program. The National
Program, with 70 percent of the funding,
consists of three separate competitions:
(1) The National Clean Diesel Funding
Assistance Program; (2) the National
Clean Diesel Emerging Technologies
Program; and (3) the SmartWay Clean
Diesel Finance Program. The State Clean
Diesel Grant and Loan Program utilizes
the remaining 30 percent of the funding.
In the first year of the program, EPA
awarded 119 grants totaling $49.2
million for diesel emissions reduction
projects and programs across the
country for cleaner fuels, verified
technologies and certified engine
configurations.
Through $300 million in funding
provided to the DERA program under
the American Reinvestment and
Recovery Act of 2009, EPA will promote
and preserve jobs while improving
public health and achieving significant
reductions in diesel emissions.
Furthermore, EPA’s National Clean
Diesel Campaign, through its Clean
Ports USA program, is working with
port authorities, terminal operators,
shipping, truck and rail companies to
promote cleaner diesel technologies and
strategies today through education,
incentives, and financial assistance for
diesel emissions reductions at ports.
Part of these efforts involves clean
diesel programs that can further reduce
emissions from the existing fleet of
diesel engines. Finally, many of the
companies operating in states and
communities suffering from poor air
quality have voluntarily entered into
Memoranda of Understanding (MOUs)
designed to ensure that the cleanest
technologies are used first in regions
with the most challenging air quality
issues.
In addition to the above innovative
programs, we are seeking comment on a
Voluntary Marine Verification Program
to address emissions from existing
Category 3 engines. This voluntary
program would extend our existing
diesel retrofit verification program to
these largest marine vessels. The
concept is described in Section IX.C.3
below.
Taken together, these voluntary
approaches can augment the
coordinated strategy and help states and
communities achieve larger reductions
sooner in the areas of our country that
need them the most. The Agency
remains committed to furthering these
VerDate Nov<24>2008

programs and others so that all of our
citizens can breathe clean healthy air.
(2) Advanced Emission Technology
Solutions are Available
Air pollution from marine diesel
exhaust is a challenging problem.
However, we believe it can be addressed
effectively through the use of existing
technology to reduce engine-out
emissions combined with highefficiency catalytic aftertreatment
technologies. As discussed in greater
detail in Section III.C, the development
of these aftertreatment technologies for
highway and nonroad diesel
applications has advanced rapidly in
recent years, so that very large emission
reductions in NOX emissions can be
achieved.
Control of NOX emissions from
Category 3 engines can be achieved with
high-efficiency exhaust emission control
technologies. Such technologies have
already been applied to meet our lightduty passenger car standards and are
expected to be used to meet the
stringent NOX standards included in
EPA’s heavy-duty highway diesel,
nonroad Tier 4, and locomotive and
marine diesel engine programs. They
have been in production for heavy duty
trucks in Europe since 2005, as well as
in many stationary source applications
throughout the world. These
technologies are discussed further in
Section III.C. While these technologies
can be sensitive to sulfur, their use will
be required only in ECAs designated
under MARPOL Annex VI, and they are
expected to be able to operate on ECA
fuel meeting a 1,000 ppm fuel sulfur.
With the lead time available and the
assurance of 1,000 ppm fuel for oceangoing vessels in 2015, as would be
required through ECA designation for
U.S. coasts, we are confident the
proposed application of advanced NOX
technology to Category 3 marine engines
will proceed at a reasonable rate of
progress and will result in systems
capable of achieving the proposed
standards on the proposed schedule.
Use of this lower sulfur fuel will also
result in substantial PM emission
reductions, since most of the PM
emissions from Category 3 engines is
due to the use of high sulfur residual
fuel.
C. Statutory Basis for Action
Authority for the actions proposed in
this documents is granted to the
Environmental Protection Agency by
sections 114, 203, 205, 206, 207, 208,
211, 213, 216, and 301(a) of the Clean
Air Act as amended in 1990 (42 U.S.C.
7414, 7522, 7524, 7525, 7541, 7542,

sections 1901–1915 of the Act to
Prevent Pollution from Ships (33 U.S.C.
1909 et seq.).
(1) Clean Air Act Basis for Action
EPA is proposing the fuel
requirements pursuant to its authority
in section 211 (c) of the Clean Air Act,
which allow EPA to regulate fuels that
contribute to air pollution which
endangers public health or welfare (42
U.S.C. 7545(c)). As discussed previously
in EPA’s Clean Air Nonroad Diesel rule
(69 FR 38958) and below in Section II
of this preamble, the combustion of high
sulfur diesel fuel by nonroad,
locomotive, and marine diesel engines
contributes to air quality problems that
endanger public health and welfare.
Section II also discusses the significant
contribution to these air quality
problems by Category 3 marine vessels.
Additional support for the procedural
and enforcement-related aspects of the
fuel controls in the proposed rule,
including the record keeping
requirements, comes from sections
114(a) and 301(a) of the CAA (42 U.S.C.
Sections 7414 (a) and 7601 (a)).
EPA is proposing emissions standards
for new Category 3 marine diesel
engines pursuant to its authority under
section 213(a)(3) of the Clean Air Act,
which directs the Administrator to set
standards regulating emissions of NOX,
volatile organic compounds (VOCs), or
CO for classes or categories of engines,
like marine diesel engines, that
contribute to ozone or carbon monoxide
concentrations in more than one
nonattainment area. These ‘‘standards
shall achieve the greatest degree of
emission reduction achievable through
the application of technology which the
Administrator determines will be
available for the engines or vehicles,
giving appropriate consideration to cost,
lead time, noise, energy, and safety
factors associated with the application
of such technology.’’
EPA is proposing a PM measurement
requirement for new Category 3 marine
diesel engines pursuant to its authority
under section 208, which requires
manufacturers and other persons subject
to Title II requirements to ‘‘provide
information the Administrator may
reasonably require * * * to otherwise
carry out the provisions of this
part* * *’’
EPA is also acting under its authority
to implement and enforce the Category
3 marine diesel emission standards.
Section 213(d) provides that the
standards EPA adopts for marine diesel
engines ‘‘shall be subject to Sections
206, 207, 208, and 209’’ of the Clean Air
Act, with such modifications that the
Administrator deems appropriate to the
E:\FR\FM\28AUP2.SGM

mstockstill on DSKH9S0YB1PROD with PROPOSALS2
44450
Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
regulations implementing these
sections.’’ In addition, the marine
standards ‘‘shall be enforced in the same
manner as [motor vehicle] standards
prescribed under section 202’’ of the
Act. Section 213(d) also grants EPA
authority to promulgate or revise
regulations as necessary to determine
compliance with and enforce standards
adopted under section 213.
As required under section 213(a)(3),
we believe the evidence provided in
Section III.C of this Preamble and in
Chapter 4 of draft Regulatory Impact
Analysis (RIA) indicates that the
stringent NOX emission standards
proposed in this NPRM for newly-built
Category 3 marine diesel engines are
feasible and reflect the greatest degree of
emission reduction achievable through
the use of technology that will be
available in the model years to which
they apply. We have given appropriate
consideration to costs in proposing
these standards. Our review of the costs
and cost-effectiveness of these standards
indicate that they will be reasonable and
comparable to the cost-effectiveness of
other mobile source emission reduction
strategies that have been required. We
have also reviewed and given
appropriate consideration to the energy
factors of this rule in terms of fuel
efficiency as well as any safety and
noise factors associated with these
proposed standards.
The information in Section II of this
preamble and Chapter 2 of the draft RIA
regarding air quality and public health
impacts provides strong evidence that
emissions from Category 3 marine diesel
engines significantly and adversely
impact public health or welfare. EPA
has already found in previous rules that
emissions from new marine diesel
engines contribute to ozone and CO
concentrations in more than one area
which has failed to attain the ozone and
carbon monoxide NAAQS (64 FR 73300,
December 29, 1999).
The NOX and PM emission reductions
expected to be achieved through the
coordinated strategy would be
important to states’ efforts to attain and
maintain the Ozone and the PM2.5
NAAQS in the near term and in the
decades to come, and would
significantly reduce the risk of adverse
effects to human health and welfare.
(2) APPS Basis for Action
EPA is proposing regulations to
implement MARPOL Annex VI
pursuant to its authority in section 1903
of the Act to Prevent Pollution from
Ships (APPS). Section 1903 gives the
Administrator the authority to prescribe
any necessary or desired regulations to
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
carry out the provisions of Regulations
12 through 19 of Annex VI.
The Act to Prevent Pollution from
Ships implements and makes Annex VI
requirements enforceable domestically.
However, certain clarifications are
necessary with respect to implementing
Regulation 13 and the requirements of
the NOX Technical Code with respect to
issuance of Engine International Air
Pollution Prevention (EIAPP)
certificates, approval of alternative
compliance methods. Clarification is
also needed with respect to the
application of the Annex VI
requirements to certain U.S. and foreign
vessels that operate in U.S. waters.
II. Air Quality, Health and Welfare
Impacts
The proposed NOX limits combined
with the ECA designation for U.S. coasts
and related proposed fuel standards are
expected to significantly reduce
emissions of NOX, PM, and SOX from
ocean-going vessels. Emissions of these
compounds contribute to nonattainment
of the NAAQS for PM and ozone. In
addition to contributing to PM
nonattainment, these engines are
emitting diesel particulate matter,
which is associated with a host of
adverse health effects, including cancer.
In addition to their health effects,
emissions from these engines also
contribute to welfare and environmental
effects including deposition, visibility
impairment and harm to ecosystems
from ozone.
This section summarizes the general
health and welfare effects of these
emissions. Interested readers are
encouraged to refer to the draft RIA for
more in-depth discussions.
A. Public Health Impacts
(1) Particulate Matter
(a) Background
Particulate matter is a generic term for
a broad class of chemically and
physically diverse substances. It can be
principally characterized as discrete
particles that exist in the condensed
(liquid or solid) phase spanning several
orders of magnitude in size. Since 1987,
EPA has delineated that subset of
inhalable particles small enough to
penetrate to the thoracic region
(including the tracheobronchial and
alveolar regions) of the respiratory tract
(referred to as thoracic particles).
Current NAAQS use PM2.5 as the
indicator for fine particles (with PM2.5
referring to particles with a nominal
mean aerodynamic diameter less than or
equal to 2.5 μm), and use PM10 as the
indicator for purposes of regulating the
coarse fraction of PM10 (referred to as
PO 00000
Frm 00010
Fmt 4701
Sfmt 4702
thoracic coarse particles or coarsefraction particles; generally including
particles with a nominal mean
aerodynamic diameter greater than 2.5
μm and less than or equal to 10 μm, or
PM10–2.5). Ultrafine particles are a subset
of fine particles, generally less than 100
nanometers (0.1 μm) in aerodynamic
diameter.
Fine particles are produced primarily
by combustion processes and by
transformations of gaseous emissions
(e.g., SOX, NOX and VOC) in the
atmosphere. The chemical and physical
properties of PM2.5 may vary greatly
with time, region, meteorology, and
source category. Thus, PM2.5 may
include a complex mixture of different
pollutants including sulfates, nitrates,
organic compounds, elemental carbon
and metal compounds. These particles
can remain in the atmosphere for days
to weeks and travel hundreds to
thousands of kilometers.17
(b) Health Effects of PM
Scientific studies show ambient PM is
associated with a series of adverse
health effects. These health effects are
discussed in detail in EPA’s 2004
Particulate Matter Air Quality Criteria
Document (PM AQCD) and the 2005 PM
Staff Paper.18 Further discussion19 of
health effects associated20 with PM can
also be found in the draft RIA for this
rule.
Health effects associated with shortterm exposures (hours to days) to
ambient PM include premature
mortality, aggravation of cardiovascular
and lung disease (as indicated by
increased hospital admissions and

the EPA is considering all available science on PM
health effects, including information which has
been published since 2004, in the development of
the upcoming PM Integrated Science Assessment
Document (ISA). A first draft of the PM ISA was
completed in December 2008 and was submitted for
review by the Clean Air Scientific Advisory
Committee (CASAC) of EPA’s Science Advisory
Board. Comments from the general public have also
been requested. For more information, see https://

lung function, altered heart rate rhythm,
and other more subtle changes in blood

health.21 Long-term exposure to PM2.5

with mortality from cardiopulmonary
disease and lung cancer, and effects on
the respiratory system such as reduced
lung function growth or development of
respiratory disease. A new analysis
shows an association between long-term
PM2.5 exposure and a measure of

exposed over the long term (one or more
years) to different levels of air pollution,

23 This study is included in the 2006 Provisional
Assessment of Recent Studies on Health Effects of
Particulate Matter Exposure. The provisional
assessment did not and could not (given a very
short timeframe) undergo the extensive critical
review by CASAC and the public, as did the PM
AQCD. The provisional assessment found that the
‘‘new’’ studies expand the scientific information
and provide important insights on the relationship
between PM exposure and health effects of PM. The
provisional assessment also found that ‘‘new’’
studies generally strengthen the evidence that acute
and chronic exposure to fine particles and acute
exposure to thoracic coarse particles are associated
with health effects. Further, the provisional science
assessment found that the results reported in the
studies did not dramatically diverge from previous
findings, and taken in context with the findings of
the AQCD, the new information and findings did
not materially change any of the broad scientific
conclusions regarding the health effects of PM
exposure made in the AQCD. However, it is
important to note that this assessment was limited
to screening, surveying, and preparing a provisional
assessment of these studies. For reasons outlined in
Section I.C of the preamble for the final PM NAAQS
rulemaking in 2006 (see 71 FR 61148–49, October
17, 2006), EPA based its NAAQS decision on the
science presented in the 2004 AQCD.

(c) Health Effects of Diesel Particulate
Matter
Marine diesel engines emit diesel
exhaust (DE), a complex mixture
composed of carbon dioxide, oxygen,
nitrogen, water vapor, carbon monoxide,
nitrogen compounds, sulfur compounds
and numerous low-molecular-weight
hydrocarbons. A number of these
gaseous hydrocarbon components are
individually known to be toxic,
including aldehydes, benzene and 1,3butadiene. The diesel particulate matter
(DPM) present in DE consists of fine
particles (< 2.5 μm), including a
subgroup with a large number of
ultrafine particles (< 0.1 μm). These
particles have a large surface area which
makes them an excellent medium for
adsorbing organics and their small size
makes them highly respirable. Many of
the organic compounds present in the
gases and on the particles, such as
polycyclic organic matter (POM), are
individually known to have mutagenic
and carcinogenic properties. Diesel
exhaust varies significantly in chemical
composition and particle sizes between
different engine types (heavy-duty,
light-duty), engine operating conditions
(idle, accelerate, decelerate), and fuel
formulations (high/low sulfur fuel).
Also, there are emissions differences
between on-road and nonroad engines
because the nonroad engines are
generally of older technology. This is
especially true for marine diesel
engines.28
After being emitted in the engine
exhaust, diesel exhaust undergoes
dilution as well as chemical and
physical changes in the atmosphere.
The lifetime for some of the compounds
present in diesel exhaust ranges from
hours to days.29

(i) Diesel Exhaust: Potential Cancer
Effects
In EPA’s 2002 Diesel Health
Assessment Document (Diesel HAD),30
exposure to diesel exhaust was
classified as likely to be carcinogenic to
humans by inhalation from
environmental exposures, in accordance
with the revised draft 1996/1999 EPA
cancer guidelines. A number of other
agencies (National Institute for
Occupational Safety and Health, the
International Agency for Research on
Cancer, the World Health Organization,
California EPA, and the U.S.
Department of Health and Human
Services) have made similar
classifications. However, EPA also
concluded in the Diesel HAD that it is
not possible currently to calculate a
cancer unit risk for diesel exhaust due
to a variety of factors that limit the
current studies, such as limited
quantitative exposure histories in
occupational groups investigated for
lung cancer.
For the Diesel HAD, EPA reviewed 22
epidemiologic studies on the subject of
the carcinogenicity of workers exposed
to diesel exhaust in various
occupations, finding increased lung
cancer risk, although not always
statistically significant, in 8 out of 10
cohort studies and 10 out of 12 casecontrol studies within several
industries. Relative risk for lung cancer
associated with exposure ranged from
1.2 to 1.5, although a few studies show
relative risks as high as 2.6.
Additionally, the Diesel HAD also relied
on two independent meta-analyses,
which examined 23 and 30 occupational
studies respectively, which found
statistically significant increases in
smoking-adjusted relative lung cancer
risk associated with exposure to diesel
exhaust of 1.33 to 1.47. These metaanalyses demonstrate the effect of
pooling many studies and in this case
show the positive relationship between
diesel exhaust exposure and lung cancer
across a variety of diesel exhaustexposed occupations.31,32
In the absence of a cancer unit risk,
the Diesel HAD sought to provide
additional insight into the significance
of the diesel exhaust-cancer hazard by

estimating possible ranges of risk that
might be present in the population. An
exploratory analysis was used to
characterize a possible risk range by
comparing a typical environmental
exposure level for highway diesel
sources to a selected range of
occupational exposure levels. The
occupationally observed risks were then
proportionally scaled according to the
exposure ratios to obtain an estimate of
the possible environmental risk. A
number of calculations are needed to
accomplish this, and these can be seen
in the EPA Diesel HAD. The outcome
was that environmental risks from
diesel exhaust exposure could range
from a low of 10¥4 to 10¥5 to as high
as 10¥3, reflecting the range of
occupational exposures that could be
associated with the relative and absolute
risk levels observed in the occupational
studies. Because of uncertainties, the
analysis acknowledged that the risks
could be lower than 10¥4 or 10¥5, and
a zero risk from diesel exhaust exposure
was not ruled out.

(ii) Diesel Exhaust: Other Health Effects
Noncancer health effects of acute and
chronic exposure to diesel exhaust
emissions are also of concern to the
EPA. EPA derived a diesel exhaust
reference concentration (RfC) from
consideration of four well-conducted
chronic rat inhalation studies showing
adverse pulmonary effects.33,34,35,36 The
RfC is 5 μg/m 3 for diesel exhaust as
measured by DPM. This RfC does not
consider allergenic effects such as those
associated with asthma or immunologic
effects. There is growing evidence,
discussed in the Diesel HAD, that
exposure to diesel exhaust can
exacerbate these effects, but the
exposure-response data are presently
lacking to derive an RfC. The EPA
Diesel HAD states, ‘‘With DPM [diesel
particulate matter] being a ubiquitous
component of ambient PM, there is an
uncertainty about the adequacy of the
existing DE [diesel exhaust] noncancer

(p. 9–19). The Diesel HAD concludes
‘‘that acute exposure to DE [diesel
exhaust] has been associated with
irritation of the eye, nose, and throat,
respiratory symptoms (cough and
phlegm), and neurophysiological
symptoms such as headache,
lightheadedness, nausea, vomiting, and
numbness or tingling of the
extremities.’’37
(iii) Ambient PM2.5 Levels and Exposure
to Diesel Exhaust PM
The Diesel HAD also briefly
summarizes health effects associated
with ambient PM and discusses the
EPA’s annual PM2.5 NAAQS of 15 μg/
m 3. There is a much more extensive
body of human data showing a wide
spectrum of adverse health effects
associated with exposure to ambient
PM, of which diesel exhaust is an
important component. The PM2.5
NAAQS is designed to provide
protection from the noncancer and
premature mortality effects of PM2.5 as
a whole.
(iv) Diesel Exhaust PM Exposures
Exposure of people to diesel exhaust
depends on their various activities, the
time spent in those activities, the
locations where these activities occur,
and the levels of diesel exhaust
pollutants in those locations. The major
difference between ambient levels of
diesel particulate and exposure levels
for diesel particulate is that exposure
accounts for a person moving from
location to location, proximity to the
emission source, and whether the
exposure occurs in an enclosed
environment.
Occupational Exposures
Occupational exposures to diesel
exhaust from mobile sources, including
marine diesel engines, can be several
orders of magnitude greater than typical
exposures in the non-occupationally
exposed population.
Over the years, diesel particulate
exposures have been measured for a
number of occupational groups. A wide
range of exposures have been reported,
from 2 μg/m 3 to 1,280 μg/m 3, for a
variety of occupations. As discussed in
the Diesel HAD, the National Institute of
Occupational Safety and Health
(NIOSH) has estimated a total of
1,400,000 workers are occupationally

Elevated Concentrations and Ambient
Exposures in Mobile Source-Impacted
Areas
Regions immediately downwind of
marine ports may experience elevated
ambient concentrations of directlyemitted PM2.5 from diesel engines. Due
to the unique nature of marine ports,
emissions from a large number of diesel
engines are concentrated in a small area.
A 2006 study from the California Air
Resources Board (CARB) evaluated air
quality impacts of diesel engine
emissions within the Ports of Long
Beach and Los Angeles in California,
one of the largest ports in the U.S.38 The
port study employed the ISCST3
dispersion model. With local
meteorological data used in the
modeling, annual average
concentrations were substantially
elevated over an area exceeding 200,000
acres. Because the ports are located near
heavily-populated areas, the modeling
indicated that over 700,000 people lived
in areas with at least 0.3 μg/m 3 of portrelated diesel PM in ambient air, about
360,000 people lived in areas with at
least 0.6 μg/m 3 of diesel PM, and about
50,000 people lived in areas with at
least 1.5 μg/m 3, of ambient diesel PM
directly from the port. This study
highlights the substantial contribution
ports can make to elevated ambient
concentrations in populated areas.
EPA recently updated its initial
screening-level analysis of a
representative selection of national
marine port areas to better understand
the populations that are exposed to
DPM emissions from these
facilities.39, 40, 41, 42 As part of this study,

locations and property boundaries of 45
marine ports.43 Census information was
used to estimate the size and
demographic characteristics of the
population living in the vicinity of the
ports. The results indicate that at least
18 million people, including a
disproportionate number of low-income
households, African-Americans, and
Hispanics, live in the vicinity of these
facilities and are being exposed to
ambient DPM levels that are 2.0 μg/m 3
and 0.2 μg/m 3 above levels found in
areas further from these facilities. These

(a) Background
Ground-level ozone pollution is
typically formed by the reaction of VOC
and NOX in the lower atmosphere in the
presence of heat and sunlight. These
pollutants, often referred to as ozone
precursors, are emitted by many types of
pollution sources, such as highway and
nonroad motor vehicles and engines,
power plants, chemical plants,
refineries, makers of consumer and
commercial products, industrial
facilities, and smaller area sources.
The science of ozone formation,
transport, and accumulation is
complex.44 Ground-level ozone is
produced and destroyed in a cyclical set
of chemical reactions, many of which
are sensitive to temperature and
sunlight. When ambient temperatures
and sunlight levels remain high for
several days and the air is relatively
stagnant, ozone and its precursors can
build up and result in more ozone than
typically occurs on a single hightemperature day. Ozone can be
transported hundreds of miles

downwind from precursor emissions,
resulting in elevated ozone levels even
in areas with low local VOC or NOX
emissions.
(b) Health Effects of Ozone
The health and welfare effects of
ozone are well documented and are
assessed in EPA’s 2006 Air Quality
Criteria Document (ozone AQCD) and
2007 Staff Paper.45,46 Ozone can irritate
the respiratory system, causing
coughing, throat irritation, and/or
uncomfortable sensation in the chest.
Ozone can reduce lung function and
make it more difficult to breathe deeply;
breathing may also become more rapid
and shallow than normal, thereby
limiting a person’s activity. Ozone can
also aggravate asthma, leading to more
asthma attacks that require medical
attention and/or the use of additional
medication. In addition, there is
suggestive evidence of a contribution of
ozone to cardiovascular-related
morbidity and highly suggestive
evidence that short-term ozone exposure
directly or indirectly contributes to nonaccidental and cardiopulmonary-related
mortality, but additional research is
needed to clarify the underlying
mechanisms causing these effects. In a
recent report on the estimation of ozonerelated premature mortality published
by the National Research Council (NRC),
a panel of experts and reviewers
concluded that short-term exposure to
ambient ozone is likely to contribute to
premature deaths and that ozone-related
mortality should be included in
estimates of the health benefits of
reducing ozone exposure.47 Animal
toxicological evidence indicates that
with repeated exposure, ozone can
inflame and damage the lining of the
lungs, which may lead to permanent
changes in lung tissue and irreversible
reductions in lung function. People who
are more susceptible to effects
associated with exposure to ozone can
include children, the elderly, and
individuals with respiratory disease
such as asthma. Those with greater
exposures to ozone, for instance due to

time spent outdoors (e.g., children and
outdoor workers), are of particular
concern.
The 2006 ozone AQCD also examined
relevant new scientific information that
has emerged in the past decade,
including the impact of ozone exposure
on such health effects as changes in
lung structure and biochemistry,
inflammation of the lungs, exacerbation
and causation of asthma, respiratory
illness-related school absence, hospital
admissions and premature mortality.
Animal toxicological studies have
suggested potential interactions between
ozone and PM with increased responses
observed to mixtures of the two
pollutants compared to either ozone or
PM alone. The respiratory morbidity
observed in animal studies along with
the evidence from epidemiologic studies
supports a causal relationship between
acute ambient ozone exposures and
increased respiratory-related emergency
room visits and hospitalizations in the
warm season. In addition, there is
suggestive evidence of a contribution of
ozone to cardiovascular-related
morbidity and non-accidental and
cardiopulmonary mortality.
(3) NOX and SOX
(a) Background
Nitrogen dioxide (NO2) is a member of
the NOX family of gases. Most NO2 is
formed in the air through the oxidation
of nitric oxide (NO) emitted when fuel
is burned at a high temperature. SO2, a
member of the sulfur oxide (SOX) family
of gases, is formed from burning fuels
containing sulfur (e.g., coal or oil
derived), extracting gasoline from oil, or
extracting metals from ore.
SO2 and NO2 can dissolve in water
vapor and further oxidize to form
sulfuric and nitric acid which react with
ammonia to form sulfates and nitrates,
both of which are important
components of ambient PM. The health
effects of ambient PM are discussed in
Section II.A.1 of this preamble. NOX
along with non-methane hydrocarbon
(NMHC) are the two major precursors of
ozone. The health effects of ozone are
covered in Section II.A.2.
(b) Health Effects of NOX
Information on the health effects of
NO2 can be found in the U.S.

concluded that the findings of
epidemiologic, controlled human
exposure, and animal toxicological
studies provide evidence that is
sufficient to infer a likely causal
relationship between respiratory effects
and short-term NO2 exposure. The ISA
concludes that the strongest evidence
for such a relationship comes from
epidemiologic studies of respiratory
effects including symptoms, emergency
department visits, and hospital
admissions. The ISA also draws two
broad conclusions regarding airway
responsiveness following NO2 exposure.
First, the ISA concludes that NO2
exposure may enhance the sensitivity to
allergen-induced decrements in lung
function and increase the allergeninduced airway inflammatory response
at exposures as low as 0.26 ppm NO2 for
30 minutes. Second, exposure to NO2
has been found to enhance the inherent
responsiveness of the airway to
subsequent nonspecific challenges in
controlled human exposure studies of
asthmatic subjects. Enhanced airway
responsiveness could have important
clinical implications for asthmatics
since transient increases in airway
responsiveness following NO2 exposure
have the potential to increase symptoms
and worsen asthma control. Together,
the epidemiologic and experimental
data sets form a plausible, consistent,
and coherent description of a
relationship between NO2 exposures
and an array of adverse health effects
that range from the onset of respiratory
symptoms to hospital admission.
Although the weight of evidence
supporting a causal relationship is
somewhat less certain than that
associated with respiratory morbidity,
NO2 has also been linked to other health
endpoints. These include all-cause
(nonaccidental) mortality, hospital
admissions or emergency department
visits for cardiovascular disease, and
decrements in lung function growth
associated with chronic exposure.

children and the elderly. During periods
of elevated ventilation, asthmatics may
experience symptomatic
bronchoconstriction within minutes of
exposure. Following an extensive
evaluation of health evidence from
epidemiologic and laboratory studies,
the EPA has concluded that there is a
causal relationship between respiratory
health effects and short-term exposure
to SO2. Separately, based on an
evaluation of the epidemiologic
evidence of associations between shortterm exposure to SO2 and mortality, the
EPA has concluded that the overall
evidence is suggestive of a causal
relationship between short-term
exposure to SO2 and mortality.
B. Environmental Impacts
(1) Deposition of Nitrogen and Sulfur
Emissions of NOX and SOX from ships
contribute to atmospheric deposition of
nitrogen and sulfur in the U.S.
Atmospheric deposition of nitrogen and
sulfur contributes to acidification,
altering biogeochemistry and affecting
animal and plant life in terrestrial and
aquatic ecosystems across the U.S. The
sensitivity of terrestrial and aquatic
ecosystems to acidification from
nitrogen and sulfur deposition is
predominantly governed by geology.
Prolonged exposure to excess nitrogen
and sulfur deposition in sensitive areas
acidifies lakes, rivers and soils.
Increased acidity in surface waters
creates inhospitable conditions for biota
and affects the abundance and
nutritional value of preferred prey
species, threatening biodiversity and
ecosystem function. Over time,
acidifying deposition also removes
essential nutrients from forest soils,
depleting the capacity of soils to
neutralize future acid loadings and
negatively affecting forest sustainability.
Major effects include a decline in
sensitive forest tree species, such as red
spruce (Picea rubens) and sugar maple
(Acer saccharum), and a loss of
biodiversity of fishes, zooplankton, and
macro invertebrates.
In addition to the role nitrogen
deposition plays in acidification,
nitrogen deposition also causes
ecosystem nutrient enrichment leading
to eutrophication that alters
biogeochemical cycles. Excess nitrogen
also leads to the loss of nitrogen
sensitive lichen species as they are
outcompeted by invasive grasses as well
as altering the biodiversity of terrestrial
ecosystems, such as grasslands and
meadows. Nitrogen deposition
contributes to eutrophication of
estuaries and the associated effects
including toxic algal blooms and fish

kills. For a broader explanation of the
topics treated here, refer to the
description in Section 2.3.1 of the draft
RIA.
There are a number of important
quantified relationships between
nitrogen deposition levels and
ecological effects. Certain lichen species
are the most sensitive terrestrial taxa to
nitrogen with species losses occurring at
just 3 kg N/ha/yr in the Pacific
Northwest, southern California and
Alaska. A United States Forest Service
study conducted in areas within the
Tongass Forest in Southeast Alaska
found evidence of sulfur emissions
impacting lichen communities.50 The
authors concluded that the main source
of nitrogen and sulfur found in lichens
from Mt. Roberts (directly north of the
City of Juneau in southeastern Alaska) is
likely the burning of fossil fuels by
cruise ships and other vehicles and
equipment in Juneau.
Lichen are an important food source
for caribou. This is causing concern
about the potential role damage to
lichens may be having on the Southern
Alaska Peninsula Caribou Herd, which
is an important food source to local
subsistence-based cultures. This herd
has been decreasing in size, exhibiting
both poor calf survival and low
pregnancy rates, which are signs of
dietary stress. Currently, there is a
complete caribou hunting ban,
including a ban on subsistence hunting.
Across the U.S., there are many
terrestrial and aquatic ecosystems that
have been identified as particularly
sensitive to nitrogen deposition. The
most extreme effects resulting from
nitrogen deposition on aquatic
ecosystems are due to nitrogen
enrichment which contributes to
‘‘hypoxic’’ zones devoid of life. Three
hypoxia zones of special concern in the
U.S. are the zones located in the Gulf of
Mexico, the Chesapeake Bay in the midAtlantic region, and Long Island Sound
in the northeast U.S.51
(2) Deposition of Particulate Matter and
Air Toxics
The combination of the proposed
CAA NOX standards along with ECA
designation through amendment to
MARPOL Annex VI would reduce NOX,
SOX, and PM2.5 emissions from ships.

Ship emissions of PM2.5 contain small
amounts of metals: nickel, vanadium,
cadmium, iron, lead, copper, zinc,
aluminum.52 53 54 Investigations of trace
metals near roadways and industrial
facilities indicate that a substantial
burden of heavy metals can accumulate
on vegetative surfaces. Copper, zinc,
and nickel are directly toxic to
vegetation under field conditions.55
While metals typically exhibit low
solubility, limiting their bioavailability
and direct toxicity, chemical
transformations of metal compounds
occur in the environment, particularly
in the presence of acidic or other
oxidizing species. These chemical
changes influence the mobility and
toxicity of metals in the environment.
Once taken up into plant tissue, a metal
compound can undergo chemical
changes, accumulate and be passed
along to herbivores, or can re-enter the
soil and further cycle in the
environment.
Although there has been no direct
evidence of a physiological association
between tree injury and heavy metal
exposures, heavy metals have been
implicated because of similarities
between metal deposition patterns and
forest decline.56 57 This correlation was
further explored in high elevation
forests in the northeast U.S. and the data
strongly imply that metal stress causes
tree injury and contributes to forest
decline in the Northeast.58
Contamination of plant leaves by heavy
metals can lead to elevated soil levels.
Trace metals absorbed into the plant
frequently bind to the leaf tissue, and

metals are transferred into the soil.59 60
Ships also emit air toxics, including
polycyclic aromatic hydrocarbons
(PAHs), a class of polycyclic organic
matter (POM) that contains compounds
which are known or suspected
carcinogens. Since the majority of PAHs
are adsorbed onto particles less than 1.0
μm in diameter, long range transport is
possible. Particles of this size can
remain airborne for days or even months
and travel distances up to 10,000 km
before being deposited on terrestrial or
aquatic surfaces.61 Atmospheric

in sediments and bioaccumulate in fresh

The deposition of airborne particles
can reduce the aesthetic appeal of
buildings and culturally important
articles through soiling, and can
contribute directly (or in conjunction
with other pollutants) to structural
damage by means of corrosion or
erosion.69 Particles affect materials
principally by promoting and
accelerating the corrosion of metals, by
degrading paints, and by deteriorating
building materials such as concrete and
limestone. Particles contribute to these
effects because of their electrolytic,
hygroscopic, and acidic properties, and
their ability to adsorb corrosive gases
(principally sulfur dioxide). The rate of
metal corrosion depends on a number of
factors, including the deposition rate
and nature of the pollutant; the
influence of the metal protective
corrosion film; the amount of moisture
present; variability in the
electrochemical reactions; the presence
and concentration of other surface
electrolytes; and the orientation of the
metal surface.
(3) Impacts on Visibility
Emissions from ships contribute to
poor visibility in the U.S. through their
primary PM2.5 emissions, as well as NOX
and SOX emissions which contribute to
the formation of secondary PM2.5.70
Visibility can be defined as the degree
to which the atmosphere is transparent
to visible light. Airborne particles
degrade visibility by scattering and
absorbing light. Visibility is important
because it has direct significance to
people’s enjoyment of daily activities in
all parts of the country. Individuals
value good visibility for the well-being
it provides them directly where they
live and work and in places where they
enjoy recreational opportunities.
Visibility is also highly valued in
significant natural areas such as
national parks and wilderness areas,
and special emphasis is given to

more information on visibility, see the
final 2004 PM AQCD as well as the 2005
PM Staff Paper.71, 72
EPA is pursuing a two-part strategy to
address visibility. First, to address the
welfare effects of PM on visibility, EPA
has set secondary PM2.5 standards
which act in conjunction with the
establishment of a regional haze
program. In setting this secondary
standard, EPA has concluded that PM2.5
causes adverse effects on visibility in
various locations, depending on PM
concentrations and factors such as
chemical composition and average
relative humidity. Second, section 169
of the Clean Air Act provides additional
authority to address existing visibility
impairment and prevent future visibility
impairment in the 156 national parks,
forests and wilderness areas categorized
as mandatory class I Federal areas (62
FR 38680–81, July 18, 1997).73 In July
1999, the regional haze rule (64 FR
35714) was put in place to protect the
visibility in mandatory class I Federal
areas. Visibility can be said to be
impaired in both PM2.5 nonattainment
areas and mandatory class I Federal
areas.

(4) Plant and Ecosystem Effects of
Ozone
Elevated ozone levels contribute to
environmental effects, with impacts to
plants and ecosystems being of most
concern. Ozone can produce both acute
and chronic injury in sensitive species
depending on the concentration level
and the duration of the exposure. Ozone
effects also tend to accumulate over the
growing season of the plant, so that even
low concentrations experienced for a
longer duration have the potential to
create chronic stress on vegetation.
Ozone damage to plants includes visible
injury to leaves and a reduction in food
production through impaired
photosynthesis, both of which can lead
to reduced crop yields, forestry
production, and use of sensitive
ornamentals in landscaping. In addition,

the reduced food production in plants
and subsequent reduced root growth
and storage below ground, can result in
other, more subtle plant and ecosystems
impacts. These include increased
susceptibility of plants to insect attack,
disease, harsh weather, interspecies
competition and overall decreased plant
vigor. The adverse effects of ozone on
forest and other natural vegetation can
potentially lead to species shifts and
loss from the affected ecosystems,
resulting in a loss or reduction in
associated ecosystem goods and
services. Lastly, visible ozone injury to
leaves can result in a loss of aesthetic
value in areas of special scenic
significance like national parks and
wilderness areas. The final 2006 ozone
AQCD presents more detailed
information on ozone effects on
vegetation and ecosystems.
C. Air Quality Modeling Results
Air quality modeling was performed
to assess the impact of the combination
of the proposed CAA NOX standards
along with ECA designation through
Amendment to MARPOL Annex VI. We
looked at impacts on future ambient
PM2.5 and ozone levels, as well as
nitrogen and sulfur deposition levels
and visibility impairment. In this
section, we present information on
current levels of pollution as well as
model projected levels of pollution for
2020 and 2030.74
The air quality modeling uses EPA’s
Community Multiscale Air Quality
(CMAQ) model. The CMAQ modeling
domain is rectangular in shape and
encompasses all of the lower 48 states,
portions of Canada and Mexico, and
areas extending into the ocean up to
1,000 nautical miles (nm), depending on
the coast. The smallest area of ocean
coverage is over the northeast U.S. In
places like Maine and Cape Cod, the
easternmost points of the contiguous
U.S., the distance to the edge of the
CMAQ modeling domain is
approximately 150 nm. The rest of the
U.S. shoreline has at least 200 nm
between the shoreline and boundary of
the air quality modeling. The CMAQ
modeling domain is described in more
detail in Section 2.4.5.2 of the draft RIA.
The performance of the CMAQ
modeling was evaluated over a 2002
74 As discussed in Section 3.7 of the draft RIA,
the inventories used for the air quality modeling in
2020 and 2030 differ slightly from each other. The
difference between 2020 and 2030 is small and was
due to an error in calculating the 200 nautical miles
distance. In addition, as discussed in Section 3.7 of
the draft RIA, the 2020 air quality control case does
not include global controls for areas that are beyond
200 nautical miles but within the air quality
modeling domain. The impact of this latter
difference is expected to be minimal.

base case. More detail about the
performance evaluation is contained
within the Section 2.4.5.4 of the draft
RIA. The model was able to reproduce
historical concentrations of ozone and
PM2.5 over the land with low amounts
of bias and error. While we are not able
to evaluate the model’s performance
over the ocean, there is no evidence to
suggest that model performance is
unsatisfactory over the ocean.
(1) Particulate Matter
The vast majority of PM emissions
from Category 3 engines are the result of
the sulfur content of the residual fuel
they use (67 FR 37569, May 29, 2002).75
Although this proposed rule would not
set PM standards, ECA designation
would require the use of fuel meeting
the most stringent MARPOL Annex VI
fuel sulfur limits, yielding significant
PM and SOX reductions.
(a) Current Levels
PM2.5 concentrations exceeding the
level of the PM2.5 NAAQS occur in
many parts of the country. In 2005, EPA
designated 39 nonattainment areas for
the 1997 PM2.5 NAAQS (70 FR 943,
January 5, 2005). These areas are
composed of 208 full or partial counties
with a total population exceeding 88
million. The 1997 PM2.5 NAAQS was
recently revised and the 2006 24-hour
PM2.5 NAAQS became effective on
December 18, 2006. Area designations
for the 2006 24-hour PM2.5 NAAQS are
expected to be promulgated in 2009 and
become effective 90 days after
publication in the Federal Register.
(b) Projected Levels
A number of state governments have
told EPA that they need the reductions
the coordinated strategy will provide in
order to meet and maintain the PM2.5
NAAQS.76 Most areas designated as not
attaining the 1997 PM2.5 NAAQS will
need to attain the 1997 standards in the
2010 to 2015 time frame, and then
maintain them thereafter. The 2006 24hour PM2.5 nonattainment areas will be
required to attain the 2006 24-hour
PM2.5 NAAQS in the 2014 to 2019 time
frame and then be required to maintain
the 2006 24-hour PM2.5 NAAQS
75 As explained in the NPRM, there were no
acceptable procedures for measuring PM from
Category 3 marine engines. Specifically, established
PM test methods showed unacceptable variability
when sulfur levels exceed 0.8 weight percent,
which was common at that time for both residual
and distillate marine fuels for Category 3 engines,
and no PM test method or calculation methodology
had been developed to correct that variability for
these engines.

Making at Docket Number: EPA–HQ–OAR–2007–
0121.

thereafter. The fuel sulfur emission
standards will become effective in 2010
and 2015, and the NOX engine emission
standards will become effective in 2016.
Therefore, the coordinated strategy
emission reductions will be useful to
states in attaining or maintaining the
PM2.5 NAAQS.
EPA has already adopted many
emission control programs that are
expected to reduce ambient PM2.5 levels
and which will assist in reducing the
number of areas that fail to achieve the
PM2.5 NAAQS. Even so, our air quality
modeling for this proposal projects that
in 2020, with all current controls but
excluding the reductions expected to
occur as a result of the coordinated
strategy, that at least 13 counties with a
population of almost 30 million may not
attain the 1997 annual PM2.5 standard of
15 μg/m 3.77 These numbers do not
account for additional areas that have
air quality measurements above the
2006 24-hour standard of 35 μg/m3. The
numbers also do not account for those
areas that are close to (e.g., within 10
percent of) the 1997 or 2006 PM2.5
standard. These areas, although not
violating the standards, will also benefit
from the additional reductions from this
rule ensuring long term maintenance of
the PM2.5 NAAQS.
Air quality analysis modeling the
expected impacts of the coordinated
strategy shows that in 2020 and 2030 all
of the modeled counties would
experience decreases in their annual
PM2.5 design values. For areas with
current annual PM2.5 design values
greater than 15 μg/m3, the modeled
future-year, population-weighted annual
PM2.5 design values are expected to
decrease on average by 0.8 μg/m3 in
2020 and by 1.7 μg/m3 in 2030.78 The
maximum decrease for annual PM2.5
design values are projected to be in
Miami, FL, with a 3.1 μg/m3 decrease
for 2020 and a 6.0 μg/m3 decrease for
2030. The air quality modeling
methodology and the projected
reductions are discussed in more detail
in Chapter 2 of the draft RIA.
(2) Ozone
(a) Current Levels
The U.S. EPA has recently amended
the ozone NAAQS (73 FR 16436, March
27, 2008). That final 2008 ozone
NAAQS rule set forth revisions to the
previous 1997 NAAQS for ozone to
provide increased protection of public
health and welfare. As of March 4, 2009,
there are 57 areas designated as
nonattainment for the 1997 8-hour
ozone NAAQS, comprising 293 full or
partial counties with a total population
of approximately 132 million people.
These numbers do not include the
people living in areas where there is a
future risk of failing to maintain or
attain the 1997 8-hour ozone NAAQS.
The numbers above likely
underestimate the number of counties
that are not meeting the ozone NAAQS
because the nonattainment areas
associated with the more stringent 2008
8-hour ozone NAAQS have not yet been
designated. Table II–1 provides an
estimate, based on 2005–07 air quality
data, of the counties with design values
greater than the 2008 8-hour ozone
NAAQS of 0.075 ppm.

three years of air quality data from later years. Also, the county numbers in this row include only the counties with monitors violating the 2008
Ozone NAAQS. The numbers in this table may be an underestimate of the number of counties and populations that will eventually be included in
areas with multiple counties designated nonattainment.
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
States with 8-hour ozone
nonattainment areas are required to take
action to bring those areas into
compliance in the future. Based on the
final rule designating and classifying 8hour ozone nonattainment areas for the
1997 standard (69 FR 23951, April 30,
2004), most 8-hour ozone nonattainment
areas will be required to attain the
ozone NAAQS in the 2007 to 2013 time
frame and then maintain the NAAQS
thereafter. Many of these nonattainment
areas will need to adopt additional
emission reduction programs, and the
NOX and VOC reductions that would
result from the combination of the
77 See Section 2.4.1.2.2 of the draft RIA,

proposed CAA NOX standards along
with ECA designation through
amendment to MARPOL Annex VI
would be particularly important for
these states. In addition, EPA’s revision
of the ozone NAAQS was completed
with the final rule published on March
27, 2008. The ozone NAAQS revision in
2008 started the process for
nonattainment areas to be designated
under that standard. While EPA is not
relying on the 2008 standard for
purposes of justifying this rule, the
emission reductions from this
rulemaking will also be helpful to states
for the more stringent ozone NAAQS.
EPA has already adopted many
emission control programs that are
expected to reduce ambient ozone levels
and assist in reducing the number of
areas that fail to achieve the ozone
NAAQS. Even so, our air quality
modeling projects that in 2020, with all
current controls but excluding the
reductions achieved through the
coordinated strategy, up to 50 counties
with a population of almost 50 million
may not attain the 2008 ozone standard
of 0.075 ppm. These numbers do not
account for those areas that are close to
(e.g., within 10 percent of) the 2008
ozone standard. These areas, although
not violating the standards, will also
benefit from the additional reductions
from this rule ensuring long-term
maintenance of the ozone NAAQS.
78 Note that the 2030 projections are based on a
100 nm ECA so are an underestimate of likely
changes to PM2.5 design values. Additional detail on

These air quality modeling results
suggest that the proposed emission
reductions would improve both the
average and population-weighted
average ozone concentrations for the
U.S. in 2020 and 2030. In addition, the
air quality modeling shows that on
average the coordinated program
described in this action would help
bring counties closer to ozone
attainment as well as assist counties
whose ozone concentrations are within
10 percent below the standard. For
example, in projected nonattainment
counties, on a population-weighted
basis, the 8-hour ozone design value
will on average decrease by 0.5 ppb in
2020 and 1.6 ppb in 2030.79 The air
quality modeling methodology and the
projected reductions are discussed in
more detail in Chapter 2 of the draft
RIA.
It should be noted that even though
our air quality modeling predicts
important reductions in nationwide
ozone levels, four counties (of 661 that
have monitored data) are expected to
experience an increase in their ozone
design values in 2030. There are two
counties in southern California, Orange
County and San Bernardino County, and
two counties in Washington, Clallam
County and Clark County, which would
experience 8-hour ozone design value
increases due to the NOX disbenefits
which occur in these VOC-limited
ozone nonattainment areas. Briefly, NOX
reductions at certain times and in some
areas can lead to increased ozone levels.
The air quality modeling methodology
(Section 2.4.5), the projected reductions
(Section 2.4), and the limited NOX
disbenefits (Section 2.4.2.2.2), are
discussed in more detail in Chapter 2 of
the draft RIA.

(c) Case Study of Shipping Emissions
and Ozone Impacts on Forests
The section below attempts to
estimate the impacts of the coordinated
strategy on ecological impacts through a
case study.
Assessing the impact of ground-level
ozone on forests in the eastern United
States involves understanding the risk/
effect of tree species to ozone ambient
concentrations and accounting for the
prevalence of those species within the
forest. As a way to quantify the risk/
effect of particular plants to groundlevel ozone, scientists have developed
ozone-exposure/tree-response functions
by exposing tree seedlings to different

changes to ozone design values. Additional detail

ozone levels and measuring reductions
in growth as ‘‘biomass loss’’.80
With knowledge of the distribution of
sensitive species and the level of ozone
at particular locations, it is possible to
estimate a ‘‘biomass loss’’ for each
species across their range. EPA
performed an analysis for 2020 in which
we examined biomass loss with and
without ship emissions to determine the
benefit of reducing these emissions on
sensitive tree species in the eastern half
of the U.S.81 The biomass loss
attributable to shipping appears to range
from 0–6.5% depending on the
particular species. The most sensitive
species in the U.S. to ozone related
biomass loss is black cherry (Prunus
serotina); the area of its range with more
than 10% total biomass loss in 2020
decreased by 8.5% in the case in which
emissions from ships were removed.
Likewise, yellow-poplar (Liriodendron
tulipifera), eastern white pine (Pinus
strobus), aspen (Populus spp.), and
ponderosa pine (Pinus ponderosa) saw
areas with more then 2% biomass loss
reduced by 2.1% to 3.8% in 2020. This
2% level of biomass loss is important,
because a consensus workshop on ozone
effects reported that a 2% annual
biomass loss causes harm due to the
potential for compounding effects over
multiple years as short-term negative
effects on seedlings affect long-term
forest health.82, 83
(3) Nitrogen and Sulfur Deposition
(a) Current Levels
Modeling conducted by the EPA for
the coordinated strategy shows that in
2020 ships would add significant
amounts to sulfur deposition in
sensitive ecological areas across the
U.S., ranging from 10% to more than
25% of total sulfur deposition along the
entire Atlantic, Gulf of Mexico, and
Pacific coastal areas of the U.S. This
same level of impact would extend
inland for hundreds of kilometers,
affecting thousands of sensitive
ecological areas. This deposition would
contribute to the serious problem

acidification causes in terrestrial and
aquatic ecosystems.
Nitrogen deposition contributes to
both acidification and nutrient
enrichment. In 2020, ships would
contribute a significant percentage of
the annual U.S. total nitrogen
deposition to many terrestrial and
aquatic areas within the U.S. that are
potentially sensitive to excess nitrogen.
The contribution from ships would
range from about 9% to more than 25%
along the entire U.S. Atlantic, Pacific
and Gulf of Mexico coastal regions. See
the draft RIA for more information and
detailed maps on sulfur and nitrogen
deposition.
(b) Projected Levels
The emissions reductions that would
result from the combination of the
proposed CAA NOX standards along
with ECA designation through
amendment to MARPOL Annex VI and
related proposed fuel standards would
significantly reduce the annual total
sulfur and nitrogen deposition occurring
in sensitive U.S. ecosystems including
forests, wetlands, lakes, streams, and
estuaries. For sulfur deposition,
adopting the coordinated strategy would
result in reductions ranging from 5% to
20% along the entire Atlantic and Gulf
coasts with higher levels of reduction,
exceeding 25%, occurring in the nearland coastal waters of the U.S. In a few
land areas on the Atlantic and Gulf
coasts, such as the southern parts of the
States of Louisiana, Texas, and Florida,
2020 sulfur deposition reductions
would be much higher, i.e., over 30%.
Along the Pacific Coast, sulfur
deposition reductions would exceed
25% in the entire Southern California
area, and the Pacific Northwest. For a
map of 2020 sulfur reductions and
additional information on these impacts
see Section 2.4.3 of the draft RIA.
Overall, nitrogen deposition
reductions in 2020 resulting from the
coordinated strategy described in this
action are less than sulfur deposition
reductions. Nitrogen deposition
reductions would range from 3% to 7%
along the entire Atlantic, Pacific and
Gulf Coasts. As with sulfur deposition
reductions, a few areas such as the
southern parts of the States of
Louisiana, Texas, and Florida would
experience larger reductions of nitrogen
up to 9%. The Pacific coastal waters
would see higher nitrogen reductions,
exceeding 20% in some instances. See
Section 2.4.3 of the draft RIA for a map
and additional information on nitrogen
deposition impacts.

class I Federal areas, international
shipping activity is contributing to
visibility degradation. In 2020, about
2.5% (0.28 DV) of visibility degradation
in the Grand Canyon National Park
located in the state of Arizona will be
from international shipping, while
almost 6% (0.81 DV) of visibility
degradation in the State of Washington’s
North Cascades National Park would be
from international shipping emissions.
For the table which contains the full
visibility results over the 133 analyzed
areas see Section 2.2.4.2 of the draft

44459
(b) Projected Levels
The air quality modeling conducted
for the coordinated strategy also was
used to project visibility conditions in
133 mandatory class I Federal areas
across the U.S. in 2020 and 2030. The
results indicate that improvements in
visibility due to OGV emissions
reductions would occur in all 133 class
I Federal areas in the future, although
all areas would continue to have annual
average deciview levels above
background in 2020 and 2030.84 The
average visibility on the 20 percent
worst days at these scenic locales is
projected to improve by 0.21 deciviews,
or 1.2 percent.
The greatest improvements in
visibilities would occur in coastal areas.
For instance, the Agua Tibia Wilderness
area (near Los Angeles) would see a 9%
improvement (2.17 DV) in 2020 as a
result of the emission reductions from
the coordinated strategy. National parks
and national wilderness areas in other
parts of the country would also see
improvements. For example, the Cape
Romain National Wildlife Refuge (South
Carolina) would have a 5%
improvement in visibility (1.16 DV) and
Acadia National Park (Maine) would
have a 4% improvement (0.76 DV) with
a 200 nm ECA. Other areas would
experience important benefits as well
due to the contribution of OGVs to
visibility impairment. For example, in
2002, about 3% of visibility impairment
in southern Florida’s Everglades
National Park was due to international
shipping (0.61 DV), and this will double
to 6% (1.35 DV) by 2020. Even in inland
(1) Overview
This section describes the
contribution of Category 3 vessels to
national emission inventories of NOX,
PM2.5, and SO2. A Category 3 vessel has
a Category 3 propulsion engine.
Emissions from a Category 3 vessel
include the emissions from both the
propulsion and auxiliary engines on
that vessel. Propulsion and auxiliary
engine emissions were estimated
separately to account for differences in
emission factors, engine size and load,
and activity.
We estimate that in 2009, Category 3
vessels will contribute almost 913,000
tons (10 percent) to the national mobile
source NOX inventory, about 71,000
tons (24 percent) to the mobile source
diesel PM2.5 inventory, and nearly
597,000 tons (80 percent) to the mobile
source SO2 inventory. Expressed as a
percentage of all anthropogenic
emissions, Category 3 vessels contribute
6 percent to the national NOX inventory,
3 percent to the national PM2.5
inventory, and 11 percent to the total
SO2 inventory in 2009. In 2030, absent
the strategy discussed in this proposal,
these vessels will contribute about 2.1
million tons (40 percent) to the mobile
source NOX inventory, 168,000 tons (75
percent) to the mobile source diesel
PM2.5 inventory, and about 1.4 million
tons (95 percent) to the mobile source
SO2 inventory. Expressed as a
percentage of all anthropogenic
emissions, Category 3 vessels will
contribute 19 percent to the national
NOX inventory, 5 percent to the national
PM2.5 inventory, and 15 percent to the
total SO2 inventory in 2030. Under this
strategy, by 2030, annual NOX emissions
from these vessels would be reduced by
1.2 million tons, PM2.5 emissions by
143,000 tons, and SO2 emissions by 1.3
million tons.85
Each sub-section below discusses one
of the three affected pollutants,
including expected emission reductions
that would result from the combination
of the proposed CAA NOX standards
along with the ECA designation through
amendment to MARPOL Annex VI and
related proposed fuel standards. Table
II–2 summarizes the impacts of these
reductions for 2020 and 2030. Table II–
3 provides the estimated 2030 NOX
emission reductions (and PM
reductions) for the coordinated strategy
compared to the Locomotive and Marine
rule, Clean Air Nonroad Diesel (CAND)
program, and the Heavy-Duty Highway
rule. Further details on our inventory
estimates are available in Chapter 3 of
the draft RIA.
As described in Chapter 3 of the draft
RIA, the ocean-going vessel emission
inventories presented in this section are
estimated by combining two sets of
emissions inventories, one for U.S. port
areas and one for operation on the open
ocean. With regard to operation on the
open ocean, it was necessary to specify
an outer boundary of the modeling
domain; otherwise, emissions from
ships operating as far away as Asia or
Europe would be included in the U.S.
emission inventory. For simplicity, we
set the outer boundary for inventory
modeling roughly equivalent to the U.S.
Exclusive Economic Zone (EEZ). It
consists of the area that extends 200
nautical miles (nm) from the official
U.S. baseline, which is recognized as
the low-water line along the coast as
marked on the official U.S. nautical
charts in accordance with the articles of
the Law of the Sea. The U.S. region was
then clipped to the boundaries of the
U.S. EEZ. While this area will exclude
emissions that occur outside the 200 nm
boundary but that are transported to the
U.S. landmass, it has the advantage of
corresponding to an area in which the
United States has a clear environmental
interest. This area also corresponds well
to the CMAQ modeling domain for most
coasts.
84 The level of visibility impairment in an area is
based on the light-extinction coefficient and a unit
less visibility index, called a ‘‘deciview’’, which is
used in the valuation of visibility. The deciview
metric provides a scale for perceived visual changes
over the entire range of conditions, from clear to
hazy. Under many scenic conditions, the average
person can generally perceive a change of one
deciview. The higher the deciview value, the worse
the visibility. Thus, an improvement in visibility is
a decrease in deciview value.
85 These emission inventory reductions include
reductions from ships operating within the 24
nautical mile regulatory zone off the California
Coastline, beginning with the effective date of the
Coordinated Strategy program elements. The
California regulation contains a provision that
would sunset the requirements of the rule if the
Federal program achieves equivalent emission
reductions. See https://www.arb.ca.gov/regact/2008/
fuelogv08/fro13.pdf at 13 CCR 2299.2(j)(1).
(4) Visibility
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
(a) Current Levels
As of March 12, 2008, over 88 million
people live in nonattainment areas for
the 1997 PM2.5 NAAQS. These
populations, as well as large numbers of
individuals who travel to these areas,
are likely to experience visibility
impairment. In addition, while visibility
trends have improved in mandatory
class I Federal areas, the most recent
data show that these areas continue to
suffer from visibility impairment. In
summary, visibility impairment is
experienced throughout the U.S., in
multi-state regions, urban areas, and
remote mandatory class I Federal areas.

(2) NOX Emission Reductions
In 2009, annual emissions from
Category 3 commercial 86 marine vessels
will total about 913,000 tons. Earlier
Tier 1 NOX engine standards became
effective in 2000, but the reductions due
to the Tier 1 standards are offset by the
growth in this sector, resulting in
increased NOX emissions of 1.4 million
tons and 2.1 million tons in 2020 and
2030, respectively.
As shown in Table II–2, the
coordinated strategy would reduce
annual NOX emissions from the current
national inventory baseline by 409,000
tons in 2020 and 1,181,000 tons in 2030.
As shown in Table II–3, the 2030 NOX
reductions for the coordinated strategy
would exceed those for the other two
nonroad rules.

(3) PM2.5 Emissions Reductions
In 2009, annual emissions from
Category 3 commercial marine vessels
will total about 71,000 tons. By 2030,
these engines, absent the coordinated
strategy, would contribute about
168,000 tons.
As shown in Table II–2, the
coordinated strategy would reduce
annual PM2.5 emissions by 94,000 tons
in 2020 and 143,000 tons in 2030. As
seen in Table II–3, the 2030 PM2.5

emission reduction would be larger than
any of the reductions achieved with
other recent rules.
(4) SO2 Emissions Reductions
In 2009, annual emissions from
Category 3 commercial marine vessels
will total about 597,000 tons. By 2030,
these engines, absent the coordinated
strategy, would contribute about 1.4
million tons.
As shown in Table II–2 the
coordinated strategy would reduce
annual SO2 emissions by 877,000 tons
in 2020 and 1.3 million tons in 2030.
III. Engine Standards
This section details the emission
standards, implementation dates, and
other major requirements being
proposed under the Clean Air Act. A
detailed discussion of the technological
feasibility of the proposed NOX
standards follows the description of the
proposed program.
Other elements of our coordinated
strategy to control emissions from OGV
are discussed in subsequent sections.
Provisions related to our Clean Air Act
fuel controls are described in Section
IV. Section V summarizes the U.S. and
Canada’s recent proposal to amend
MARPOL Annex VI to designate much
of the U.S. and Canadian coasts as an
PO 00000

Emission Control Area.87 Finally,
provisions revising our Clean Air Act
test procedures and related certification
requirements, provisions to implement
MARPOL Annex VI through APPS, and
various changes we are considering to
our Categories 1 and 2 (marine diesel
engines with per cylinder displacement
less than 30 liters per cylinder) marine
diesel engine program are described in
Section VI.
A. What Category 3 Marine Engines are
Covered?
Consistent with our existing marine
diesel emission control program, the
proposed engine emission standards
would apply to any new marine diesel
engine with per cylinder displacement
at or above 30 liters installed on a vessel
flagged or registered in the United
States.
With regard to marine diesel engines
on foreign vessels that enter U.S. ports,
we are proposing to retain our current
approach and not apply this Clean Air
Act program to those engines. This is
appropriate because engines on foreign
vessels are subject to the same NOX
limits through MARPOL Annex VI, and
the United States can enforce
compliance pursuant to Annex VI and
the recent amendments to the Act to
Prevent Pollution from Ships (33 USC

Support Document can be found at https://

28AUP2
Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
1901 et seq.). At the same time,
however, the effectiveness of this
approach is contingent on the
designation of U.S. coasts as an ECA
pursuant to MARPOL Annex VI, since
the Annex VI Tier III NOX limits are
geographic in scope and apply only in
designated ECAs. We anticipate that
MARPOL Annex VI will be amended to
include the U.S. and Canadian
government proposal. If, however, the
proposed amendment is not adopted in
a timely manner by IMO, we intend to
take supplemental action to control
harmful emissions from all vessels
affecting U.S. air quality. Section V
contains a description of the ECA
designation process and further
discussion of the application of the Act
to engines on foreign vessels if ECA
designation is delayed or not approved.
The combination of this Clean Air Act
program, MARPOL Annex VI, and APPS
will apply comparable emission
standards to the vast majority of vessels
entering U.S. ports or operating in U.S.
waters.88 Most significantly, these
vessels will be required to meet the NOX
limits described below. As is described
later in this Section III and in Section
VI, there would be some minor
differences between the proposed Clean
Air Act program and the requirements
that apply under MARPOL Annex VI.
Nevertheless, with respect to U.S. air
quality, these differences would have a
negligible effect on emissions from
foreign vessels.
Although we are not proposing
standards for existing engines on vessels
already in the U.S. fleet, we are seeking
comment on a programmatic alternative
that would help reduce emissions from
those engines. This Voluntary Marine
Verification Program is described in
Section IX.
B. What Standards are we Proposing for
Freshly Manufactured Engines?
This subsection details the emission
standards (and implementation dates)
we are proposing for freshly
manufactured (i.e., new) Category 3
engines on U.S. vessels. As described in
Section III.C, we believe the proposed
standards will be challenging to
manufacturers, yet ultimately feasible
and cost-effective within the proposed
lead time. These standards, along with
other parts of our program, are the
outcome of our work with stakeholders
44461
to resolve the challenges associated with
applying advanced diesel engine
technology to Category 3 engines to
achieve significant NOX reductions.
(1) NOX Standards
We are proposing new NOX emission
standards for Category 3 marine diesel
engines. Our existing Tier 1 NOX
standards for Category 3 engines are
dependent on the rated speed of the
engine for speeds between 130
revolutions per minute (rpm) and 2000
rpm. Fixed standards apply for lower
and higher speeds. Thus, the standards
are expressed as an equation that
applies for speeds between 130 rpm and
2000 rpm, along with fixed values that
are calculated from the equation for 130
rpm and 2000 rpm that apply for lower
and higher speeds. This was done to
account for the fact that brake-specific
NOX emissions are inherently higher for
lower speed engines (and lower for
higher speed engines). Note that this
same approach is used by the IMO for
the same technical reasons. We are
proposing to continue this approach for
Tier 2 and Tier 3, as shown in Table III–
1.

Significant reductions can be achieved
in the near term with little or no impact
on overall vessel performance. These
technologies include traditional engineout controls such as electronicallycontrolled high-pressure common-rail
fuel systems, turbocharger optimization,
compression-ratio changes, and
electronically-controlled exhaust valves.
We are setting a near-term NOX
emission standard requiring a reduction
of approximately 20 percent below the
current Tier 1 standard beginning 2011.
(a) Tier 2 NOX Limits
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
Our analysis, which is described in
the draft RIA, shows that these
standards will give the greatest degree of
emission control achievable considering
compliance costs, lead time, and other
relevant factors. The technological bases
are also discussed briefly below.
Note that other important provisions
related to compliance with these
standards are described in Section VI.
This includes provisions to ensure
effective control of NOX emissions over
a broad range of operating conditions.
(b) Tier 3 NOX Limits
We are proposing new Tier 2 NOX
emission standards for Category 3
marine diesel engines. In-cylinder
emission control technology for
Category 3 marine engines has
progressed substantially in recent years.
While the Tier 2 standards will
achieve modest reductions quickly, the
proposed Tier 3 standards are intended
to achieve much greater emission
reductions through the use of advanced
aftertreatment such as selective catalytic
reduction (SCR). These standards would
achieve reductions of about 80 percent
from the current Tier 1 standards. As
explained in Section IX.B below
regarding regulatory alternatives, we
evaluated the possibility of requiring the
Tier 3 limits on an earlier schedule than
2016. However, we found that a
schedule requiring Tier 3 limits prior to
2016 had significant feasibility issues,
and are therefore proposing the 2016
implementation date for Tier 3
standards. Under the proposed
approach, manufacturers of Category 3
engines will have about the same
amount of lead time allowed
manufacturers for smaller marine
engines and locomotives.
88 Certain foreign public vessels such as military
vessels and foreign vessels in innocent passage may
be exempt.

(2) PM and SOX Standards
We are not proposing new engine
standards for PM or SOX emissions. We
intend to rely instead on the use of
cleaner fuels as described in Section IV
and V. SOX emissions and the majority
of the direct PM emissions from
Category 3 marine engines operated on
residual fuels are a direct result of fuel
quality, most notably the sulfur in the
fuel, and engine-based PM controls are
not currently feasible for engines using
these fuels. Other components of
residual fuel, such as ash and heavy
metals, also contribute directly to PM.
Using cleaner distillate fuel is the
most effective means to achieve
significant PM and SOX reductions for
Category 3 engines. We are proposing
substantial reductions in the sulfur
content of fuel purchased in the U.S. for
use in an ECA. This complements
Annex VI which requires that fuels used
in ECAs around the world have sulfur
levels below 1,000 ppm. This sulfur
limit is expected to necessitate the use
of distillate fuel which will result not
only in reductions in sulfate PM
emissions, but also reductions in
organic PM and metallic ash particles in
the exhaust.
Even though the sulfur limit is much
lower than current levels, it is not clear
if this fuel sulfur level would be low
enough to allow Category 3 engines to
be equipped with the catalytic PM
filters similar to those being used by
trucks today. If we were to require
technology that needs lower sulfur fuel,
such as 15 ppm, ship operators would
need to have access to this fuel around
the world. Operating on higher sulfur
fuel, such as for outside of our waters,
could otherwise result in damage to the
PM control equipment. At this time, it
is not clear if 15 ppm sulfur fuel could
be made available around the world. In
any case, the 1,000 ppm sulfur fuel
requirement alone will eliminate 85
percent of PM emissions from ships
operating in ECAs.
To further our understanding of PM
emissions from ships, we are proposing
to require engine manufacturers to
measure and report PM emissions even
though we are not proposing a PM
standard. The information gathered will
help support our efforts as we continue
to evaluate the feasibility of achieving
further PM reductions through enginebased controls. It will also help us to
better characterize the PM emission
rates associated with operating Category
3 engines on distillate fuel. If we
determine that further PM reductions
are feasible or that a specific PM limit
is necessary to ensure anticipated
reductions in PM emissions from ships,
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
we may propose PM standards for
Category 3 engines in the future.
(3) HC and CO Standards
We are proposing HC and CO
standards of 2.0 g/kW-hr and 5.0 g/kWhr, respectively. Emission control
technologies for C3 marine engines have
been concentrated on reducing NOX and
PM emissions, but these emission
standards will prevent increases in
emissions of HC and CO that might
otherwise occur as a result of use of
certain technologies for controlling
NOX, such as those that significantly
degrade combustion efficiency.
(4) CO2 Standards
We are not proposing to adopt CO2
standards for marine diesel engines at
this time. Marine diesel engines are
included in other ongoing Agency
actions, including our Advance Notice
of Proposed Rulemaking (ANPRM) for
mobile sources (73 FR 44353, July 30,
2008) and our Greenhouse Gas
Reporting Rule (74 FR 16448, April 10,
2009). In addition, EPA is participating
in the U.S. Government delegation to
IMO, which is currently engaged in
negotiations for an international
program to address greenhouse
emissions from ships.
C. Are the Standards Feasible?
We have analyzed a variety of
technologies available for NOX
reduction in the Category 3 marine
sector. As described in more detail in
our draft RIA, we are projecting that
marine diesel engine manufacturers will
choose to use in-cylinder, or engine
design-based emission control
technologies to achieve the 15 to 20
percent NOX reductions required to
meet the proposed Tier 2 standard. To
achieve the 80 percent NOX reductions
required to meet the proposed Tier 3
standard, we believe many
manufacturers will choose SCR exhaust
aftertreatment technology. In addition,
manufacturers may choose a
combination of other in-cylinder
technologies, such fuel-water
emulsification, direct water injection,
intake air humidification, or exhaust gas
recirculation (EGR) to reduce NOX
emissions and meet the proposed
standards. These ‘‘in-cylinder’’
approaches could be calibrated and
applied in one manner to achieve Tier
3 NOX levels when operating with an
ECA, and then adjusted, or re-calibrated,
in another manner to achieve Tier 2
NOX levels when operating outside an
ECA.
The in-cylinder, or engine-out, NOX
emissions of a diesel engine can be
controlled by utilizing engine design
PO 00000
Frm 00022
Fmt 4701
Sfmt 4702
and calibration parameters (e.g., fuel
delivery and valve timing) to limit the
formation of NOX. NOX formation rate
has a strong exponential relationship to
combustion temperature. Therefore,
high temperatures result in high NOX
formation rates.89 90 Any changes to
engine design and calibration which can
reduce the peak temperature realized
during combustion will also reduce
NOX emissions. Many of the approaches
and technologies for reducing incylinder NOX emissions are discussed
in our draft RIA.
SCR is a commonly-used technology
for meeting stricter NOX emissions
standards in diesel applications
worldwide. Stationary power plants
fueled with coal, diesel and natural gas
have used SCR for three decades as a
means of controlling NOX emissions,
and European heavy-duty truck
manufacturers are currently using this
technology to meet Euro 5 emissions
limits. To a lesser extent, SCR has been
introduced on diesel engines in the U.S.
market, but the applications have been
limited to marine ferryboat and
stationary electrical power generation
demonstration projects in California and
several of the Northeast states. SCR
systems are currently being designed
and developed for use on ocean-going
vessels worldwide, and we project that
SCR will continue to be a viable
technology for control of Category 3
NOX emissions. A more detailed
discussion of SCR technology can be
found in our draft RIA.
IV. Fuel Standards
A. Background
EPA is proposing emissions standards
for Category 3 (C3) engines that are
consistent with those recently adopted
as amendments to MARPOL Annex VI.
As amended, Annex VI includes revised
fuel sulfur standards for use in engines
onboard ships, and it also set more
stringent fuel sulfur limits for ‘‘any fuel
oil used onboard ships * * * operating
within an Emission Control Area’’
(Annex VI, Regulation 14).
Under the Annex, the process by
which an Emission Control Area (ECA)
is to be designated is through
amendment of the Annex. The U.S. and
Canadian governments have submitted a
proposal to amend MARPOL Annex VI
to designate an ECA to include much of
the U.S. and Canadian coastlines.
Specifically, the proposed ECA would

include the entire coastline for the
contiguous 48 states, Southeastern
Alaska, and the Main Hawaiian Islands,
extending to a distance of 200 nautical
miles from the coastline. We anticipate
that this amendment will be considered
at the next Marine Environment
Protection Committee (MEPC 59) which
is scheduled for July 2009. We expect
that the amendment will be adopted in
March 2010, at MEPC 60. This approval
date is roughly three months after the
intended date for promulgation of the
final rule.
EPA is in this notice proposing fuel
sulfur limits under section 211(c) of the
Clean Air Act that match the limits that
apply under Annex VI in ECAs. The
adoption of such standards would: (1)
Forbid the production and sale of fuel
oil above 1,000 ppm sulfur for use in the
waters within the proposed ECA (as
well as internal U.S. waters); 91 and (2)
allow for the production and sale of up
to 1,000 ppm sulfur fuel for use in C3
marine vessels.92
The majority of vessels with a C3
propulsion engine operate on highsulfur, heavy fuel oil (HFO) (also known
as residual, or bunker, fuel). Due to their
use of heavy fuel, these marine diesel
engines have very high PM and SO2
emissions. Sulfur in the fuel is emitted
from engines primarily as SO2; however
a small fraction is emitted as sulfur
trioxide (SO3) which immediately forms
sulfate and is emitted as PM by the
engine. In addition, much of the SO2
emitted from the engine reacts in the
atmosphere to form secondary PM.
Reductions in residual fuel sulfur levels
would lead to significant sulfate PM and
SO2 emission reductions which would
provide dramatic environmental and
public health benefits. However, in most
cases, fuels that meet the long-term fuel
sulfur standards will likely be distillate
fuels, rather than HFO. In addition to
reductions in sulfate PM, switching
from HFO to distillate fuel may reduce
black carbon emissions, fine particle
counts, organic carbon, and metallic ash
particles.
91 For the purposes of this proposal, the term
‘‘ECA’’ as it is used in this Section IV refers to both
the area of the proposed ECA and internal U.S.
waters. Though the outer limits of the proposed
sulfur limitation are the same as for the proposed
ECA, the sulfur limitation in this proposal is not
dependent on MEPC approval of the ECA.
92 For the purpose of the discussion in this
section, ‘‘Category 3 vessel’’ refers to a commercial
vessel with a Category 3 propulsion engine;
‘‘Category 2 vessel’’ refers to a commercial or
recreational vessel with a Category 2 propulsion
engine; and ‘‘Category 1 vessel’’ refers to a
commercial or recreational vessel with only
Category 1 or smaller engines. The proposed fuel
provisions here apply to all of the engines on a
given vessel.
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
HFO sold for use by these vessels is
currently not subject to any EPA sulfur
limits (as it is not regulated by our
current sulfur program) and generally
has very high levels of sulfur. The
proposed modifications to our existing
diesel fuel program will prohibit the
production and sale of this fuel for use
in an ECA. Instead, fuel sold for use in
an ECA would not be allowed to exceed
a sulfur content of 1,000 ppm. In a
complementary fashion, the amendment
to MARPOL Annex VI designating the
U.S. ECA will ensure that fuel used in
an ECA, including fuel purchased in
another country but used within the
U.S. ECA, also meets a 1,000 ppm sulfur
limit. Under our proposed regulations,
fuel sold for use by C3 vessels in the
U.S. ECA will be allowed to have a
sulfur content as high as this 1,000 ppm
sulfur limit, while fuel sold for use in
Category 1 (C1; marine diesel engines
up to 7 liters per cylinder displacement)
and Category 2 (C2; marine diesel
engines from 7 to 30 liters per cylinder)
vessels would continue to be subject to
the nonroad, locomotive, and marine 93
(NRLM) diesel fuel sulfur requirements.
In the event that the U.S. ECA is not
approved in a timely manner, we will
revisit the standards being proposed
here in that context.
B. Current Diesel Fuel Standards
The Nonroad Diesel program
(finalized on June 29, 2004 (69 FR
38958)) reduces the sulfur content of
NRLM diesel fuel from uncontrolled
levels down to a maximum sulfur level
of 15 ppm. Refiners and importers are
required to produce or import all NRLM
diesel fuel at a sulfur level of 15 ppm
or less by June 1, 2014. The main
compliance mechanism of the diesel
sulfur program is the Designate and
Track (D&T) provisions, which allows
NRLM diesel fuel to be distinguished
from similar products (e.g., heating oil)
and yet provides a means for diesel fuel
to be fungibly transported through the
fuel production and distribution system.
Under D&T, refiners and importers are
required to designate the type and sulfur
level of each batch of fuel produced or
imported. As this fuel is transferred
through the distribution system, product
transfer documents (PTDs) must be
exchanged each time the batch changes
custody. Along with PTDs, other
required elements of D&T include
quarterly and annual reporting, fuel
pump labeling, and recordkeeping.
93 For the purposes of this proposal (and the
proposed 40 CFR Part 80 regulations), the term
‘‘marine’’ as it is used here refers to Category 1 and
2 marine diesel engines unless otherwise stated.
PO 00000
Frm 00023
Fmt 4701
Sfmt 4702
44463
The Nonroad Diesel program also
contains certain provisions to ease
refiners’ transition to the lower sulfur
standards and to enable the efficient
distribution of all diesel fuels. These
provisions, as discussed more below in
Section IV.B.2, include special
provisions for qualified small refiners,
transmix processors, and entities in the
fuel distribution system.
(1) Scope of the Nonroad Diesel Fuel
Program
The sulfur standards finalized by the
Nonroad Diesel rule apply to all the
diesel fuel that is produced and sold for
use in NRLM diesel applications (all
fuel used in NRLM diesel engines,
except for fuels heavier than a No. 2
distillate used in Category 2 and 3
marine engines 94 and any fuel that is
exempted for national security or other
reasons). While the Nonroad Diesel rule
did not set sulfur standards for other
distillate fuels (such as jet fuel, heating
oil, kerosene, and No. 4 fuel oil), it did
implement provisions to prevent the
inappropriate use of heating oil and
other higher sulfur distillate fuels in
NRLM and locomotive and marine (LM)
diesel applications. Sale of distillate
fuels for use in nonroad, locomotive, or
marine diesel engines will generally be
prohibited unless the fuel meets the
diesel fuel sulfur standards of 40 CFR
Part 80.95 The regulated fuels under our
diesel fuel sulfur program include those
fuels listed in the regulations at 40 CFR
80.2(qqq).
The current sulfur standards do not
apply to: (1) No. 1 distillate fuel used to
power aircraft; (2) Number 4, 5, and 6
fuels (e.g., residual fuels or residual fuel
blends, intermediate fuel oil (IFO)
Heavy Fuel Oil Grades 30 and higher),
used for stationary source purposes; (3)
any distillate fuel with a T–90
distillation point greater than 700 °F,
when used in Category 2 or 3 marine
diesel engines (this includes Number 4,
5, and 6 fuels (e.g., IFO Heavy Fuel Oil
Grades 30 and higher), including fuels
meeting the American Society for
Testing and Materials (ASTM)
specifications DMB, DMC, and RMA–10
and heavier); and (4) any fuel for which
a national security or research and
development exemption has been
approved or fuel that is exported from
94 Category 3 marine engines frequently are
designed to use residual fuels and include special
fuel handling equipment to use the residual fuel.
95 For the purposes of the diesel sulfur program,
the term heating oil basically refers to any No. 1 or
No. 2 distillate other than jet fuel, kerosene, and
diesel fuel used in highway or NRLM applications.
For example, heating oil includes fuel which is
suitable for use in furnaces and similar applications
and is commonly or commercially known or sold
as heating oil, fuel oil, or other similar trade names.

fuel with a T–90 greater than 700 °F will
not be subject to the sulfur standards
when used in Category 2 or 3 marine
engines was intended to exclude fuels
heavier than No. 2 distillate, including
blends containing residual fuel. In
addition, residual fuel is not subject to
the sulfur standards.
While many marine diesel engines
use No. 2 distillate, ASTM
specifications for marine fuels identify
four kinds of marine distillate fuels:
DMX, DMA, DMB, and DMC. DMX is a
special light distillate intended mainly
for use in emergency engines. DMA
(also called marine gas oil, or ‘‘MGO’’)
is a general purpose marine distillate
that contains no trace of residual fuel.
These fuels can be used in all marine
diesel engines but are primarily used by
Category 1 engines. DMX and DMA
fuels intended for use in any marine
diesel engine are subject to EPA’s fuel
sulfur standards.
DMB, also called marine diesel oil, is
not typically used with Category 1
engines, but is used for Category 2 and
3 engines. DMB is allowed to have a
trace of residual fuel, which can be high
in sulfur. This contamination with
residual fuel usually occurs due to the
distribution process, when distillate is
brought on board a vessel via a barge
that has previously contained residual
fuel, or using the same supply lines as
are used for residual fuel. DMB is
produced when fuels such as DMA are
brought on board the vessel in this
manner. EPA’s sulfur standards do
apply to the distillate that is used to
produce the DMB, for example the DMA
distillate, up to the point that it becomes
DMB. However, DMB itself is not
subject to the EPA sulfur standards
when it is used in Category 2 or 3
engines.
DMC is a grade of marine fuel that
may contain some residual fuel and is
often a residual fuel blend. This fuel is
similar to No. 4 diesel, and can be used
in Category 2 and Category 3 marine
diesel engines. DMC is produced by
blending a distillate fuel with residual
fuel, for example at a location
downstream in the distribution system.
EPA’s sulfur standards apply to the
distillate that is used to produce the
DMC, up to the point that it is blended
with the residual fuel to produce DMC.
However, DMC itself is not subject to
the EPA sulfur standards when it is
used in Category 2 or 3 marine engines.
Residual fuel is not covered by the
sulfur content standards as it is not a
distillate fuel. Residual fuel is typically
designated by the prefix RM (e.g., RMA,
RMB, etc.). These fuels are also
identified by their nominal viscosity
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
(e.g., RMA10, RMG35, etc.). Most
residual fuels require treatment by an
onboard purifier-clarifier centrifuge
system, although RMA and RMB do not
require this.
The distillation criterion adopted by
EPA, T–90 greater than 700 °F, was
designed to identify those fuels that are
not subject to the sulfur standards when
used in Category 2 or 3 marine diesel
engines. It is intended to exclude DMB,
DMC, and other heavy distillates or
blends, when used in Category 2 or 3
marine diesel engines. We are not
proposing to amend this provision in
this action. However, under this
proposal, all of these fuels, and any
other diesel fuels or fuel oils, would be
subject to a 1,000 ppm sulfur limit if
they are produced or sold for use in an
ECA.
(2) Flexibilities
Compliance flexibilities were
provided in the nonroad diesel sulfur
regulations for qualified small refiners
(69 FR 39047; Section IV.B.1) and for
transmix processors (69 FR 39045;
Section IV.A.3.d). Small refiners were
provided, among other flexibility
options, additional time for compliance
with the 15 ppm NRLM standard, until
June 1, 2014. Transmix processors, who
distill off-specification interface
mixtures of petroleum products from
pipeline systems into gasoline and
distillate fuel, have a simple refinery
configuration that does not make it costeffective for them to install and operate
a hydrotreater to reduce distillate fuel
sulfur content. As a result, transmix
processors were provided with the
flexibility to continue to produce all of
their NRLM diesel fuel to meet the 500
ppm sulfur standard until June 1, 2014,
and all of their LM diesel fuel to meet
a 500 ppm sulfur limit indefinitely. The
latter flexibility also allows for an outlet
for off-spec fuel that may be produced
in the distribution system.
The D&T provisions, first established
to distinguish highway from nonroad
500 ppm fuel, were thus continued
beyond 2014 to ensure that 500 ppm
NRLM could be distinguished from
similar fuel (e.g., heating oil that has a
sulfur level of 500 ppm). In 2014 and
beyond, D&T is essential to ensure that
heating oil is not being inappropriately
shifted downstream of the refiner into
the NRLM and LM diesel fuel markets,
circumventing the NRLM standards (as
mentioned above in Section IV.B.1).
Provisions in the Nonroad Diesel rule to
ensure that heating oil is not used in
NRLM applications include the use of a
fuel marker to distinguish heating oil
from NRLM and LM diesel fuel, dye
solvent yellow 124, which is added to
PO 00000
Frm 00024
Fmt 4701
Sfmt 4702
heating oil at the terminal level. The
D&T provisions also provided parties in
the diesel fuel industry with inherent
flexibility. D&T maximizes the
efficiency of the distribution system by
allowing for fungible distribution of
physically similar products, and
minimizing the need for product
segregation. Under D&T, diesel fuel with
similar sulfur levels can be fungibly
shipped up to the point of distribution
from a terminal (where off-highway
diesel fuels must be dyed red, pursuant
to Internal Revenue Service (IRS)
requirements, to indicate its tax exempt
status).
(3) Northeast/Mid-Atlantic Area
In the Northeast, heating oil is
distributed in significant quantities.
Discussions with terminal operators in
the Northeast (and other representatives
of heating oil users and distributors)
during the development of the Nonroad
Diesel rule revealed concerns that the
heating oil marker requirement would
represent a significant burden on
terminal operators and users of heating
oil given the large volume of heating oil
used in the Northeast. These parties
suggested that if EPA prohibited the sale
and use of diesel fuel produced by those
utilizing the flexibilities described
above, this area could be exempted from
the marker requirement.
Thus, the Northeast/Mid-Atlantic
(NE/MA) area was developed (69 FR
39063, Section IV.D.1.b.ii; see also 40
CFR 80.510(g) for the specific states and
counties that comprise the NE/MA
area). As there would be no way to
distinguish heating oil from 500 ppm
NRLM and 500 ppm LM diesel fuel in
2014 and beyond without the fuel
marker, these fuel types are not allowed
to be produced/imported, distributed
and/or sold in the NE/MA area during
this time period (500 ppm NRLM diesel
fuel may not be produced/imported,
distributed and/or sold in the NE/MA
area after 2012).
Similarly, high sulfur NRLM
(HSNRLM) produced through the use of
credits is not allowed in Alaska.
However, EPA-approved small refiners
in Alaska may produce HSNRLM diesel
fuel. To receive this approval, a small
refiner must provide EPA with a
compliance plan showing how their
HSNRLM diesel fuel will be segregated
from all other distillate fuels through its
distribution to end-users.

C. Applicability
Assuming adoption of an amendment
to MARPOL Annex VI establishing a
U.S. ECA, the fuel used in that ECA
cannot exceed 1,000 ppm sulfur
beginning January 1, 2015.96 As
mentioned above, we are proposing to
incorporate a similar 1,000 ppm sulfur
limit into our CAA regulations at 40
CFR Part 80 through both a prohibition
96 Annex VI, Regulation 14 (located in the
rulemaking docket, EPA–HQ–OAR–2007–0121–

on the production and sale of fuel oil
above 1,000 ppm sulfur for use in any
marine vessels (C1, C2, and C3) in the
area of the U.S. ECA, and an allowance
for the production and use of 1,000 ppm
sulfur fuel to be used in any engine on
C3 marine vessels. We are proposing
that fuel produced and sold for use in
any engine on C1 and C2 marine vessels
would continue to be subject to the
existing diesel sulfur requirements
which are more stringent than those
being proposed in this action for C3

marine vessels; however, we request
comment on whether engines on C2
marine vessels should also be allowed
to use 1,000 ppm ECA fuel similar to
those on C3 marine vessels.
Discussions with stakeholders in the
diesel fuel production and distribution
industry have indicated that they
anticipate that most (if not all) fuel oil
that could meet a 1,000 ppm sulfur
standard would be considered a
distillate or diesel fuel, because at a
E:\FR\FM\28AUP2.SGM

mstockstill on DSKH9S0YB1PROD with PROPOSALS2
1,000 ppm sulfur level it is nearly
impossible for fuel to have a T–90
distillation point at or above 700 °F (i.e.,
be considered residual fuel). As
discussed in Section IV.B.1, fuel with a
T–90 less than 700 °F would be required
to meet the standards of our existing
diesel sulfur program which, in 2014
and beyond, is 15 ppm. We believe that
because of the limits on the sulfur
content of fuel used in ECAs, the
existing diesel fuel sulfur program
should be revised to allow for the
production, distribution, purchase, and
use of 1,000 ppm sulfur fuel oil for use
in engines on C3 marine vessels.
Therefore, we are proposing a new 1,000
ppm sulfur category for fuel oil
produced and purchased for use in any
engine on a C3 marine vessels (called
‘‘ECA marine fuel’’). This proposed fuel
sulfur requirement would largely
supplement the existing diesel fuel
sulfur requirements and would
harmonize EPA’s diesel sulfur program
with the requirements of Annex VI.
Under this proposed action, owners of
Category 3 marine vessels would be able
to purchase and use 1,000 ppm sulfur
fuel, which will allow those vessels to
comply with the sulfur limits in the U.S.
ECA (and any other ECA worldwide)
and in U.S. internal waters.
D. Fuel Sulfur Standards
As discussed above in Section IV.C, in
addition to the prohibition on the sale
of fuel greater than 1,000 ppm sulfur for
use in any marine vessel operating
within the U.S. ECA, we are also
proposing the allowance of the
production, distribution, and sale of
1,000 ppm sulfur ECA marine fuel,
which we discuss more in this section.
Prior to this action and, pending the
establishment of the North American
ECA, the kind of fuel produced and sold
for use by C3 marine vessels had
uncontrolled sulfur levels as it was not
subject to the NRLM sulfur limits. This
was reflected in the regulations by
exempting these kinds of fuel from the
definition of NRLM diesel fuel and the
NRLM sulfur limits (40 CFR 80.2(nnn)).
The combined effect of Annex VI and
these regulations is to require that any
fuel sold for use in any engine on a C3
marine vessel operating in an ECA be
1,000 ppm sulfur or lower. Fuel oil used
or sold for use in C3 marine vessels in
an ECA will therefore go from
uncontrolled, high sulfur levels to no
higher than 1,000 ppm sulfur. Under
Annex VI, fuel with sulfur levels greater
than 1,000 ppm cannot be used in a
marine vessel operating in an ECA, no
matter where the fuel is purchased.
Consistent with this, the proposed
section 211(c) controls would prohibit
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
the production and sale of any fuel for
use in the U.S. ECA that is above 1,000
ppm sulfur.
The requirements for 1,000 ppm
sulfur fuel oil apply to the North Sea,
the Baltic Sea, and any other ECAs
established around the world, so this
fuel will be produced by refiners in
other countries. Under EPA’s current
NRLM program, this 1,000 ppm sulfur
fuel would be subject to the 15 ppm
NRLM sulfur limit in 2014 and later. If
EPA were to require that fuel produced,
distributed, and sold for use for C3
vessels in the U.S. ECA meet the 15
ppm sulfur standard after 2014, we
believe that C3 vessel owners would
simply purchase 1,000 ppm sulfur fuel
elsewhere to be used here in the U.S.
ECA. This could be an extremely
inefficient process for ship owners. It
would also mean a loss of sales for U.S.
refiners of fuel that these C3 vessel
owners purchase. These impacts would
add to the costs and burdens of the
program with no corresponding
environmental benefit. Therefore, we
believe that it is reasonable to allow
U.S. refiners and importers to produce
1,000 ppm sulfur fuel for use by C3
vessels. Thus, we are proposing and
requesting comment on a new fuel
sulfur standard of 1,000 ppm for fuel
produced, distributed, and sold for use
in C3 marine vessels. While we would
expect use of this fuel to be
concentrated in the area of the U.S. ECA
(and any other ECA) and U.S. internal
waters, we are allowing its use by C3
marine vessels in all locations, to
encourage its general use. We are
proposing that after 2014, no fuel above
15 ppm could be used in C1 or C2
vessels; however, we request comment
on whether or not C2 vessels should be
treated similarly to C3 vessels.
We note that the combination of the
Annex VI ECA provisions and the
modifications proposed in this action
for the diesel sulfur program will
achieve very significant benefits
compared to the existing program. The
production and use of 1,000 ppm ECA
marine fuel, as well as 15 ppm NRLM
diesel fuel, will replace much higher
sulfur fuel usage, and there is no
additional benefit to be gained by
requiring the sale of 15 ppm sulfur
diesel fuel for use by C3 vessels as a
practical matter because we believe C3
vessels will simply purchase 1,000 ppm
sulfur fuel elsewhere. In order to
incorporate these modifications into our
existing program under the Clean Air
Act, we need to create a new fuel
designation for allowable fuel under our
program.

(1) Proposed Amendments to the
Existing Diesel Fuel Sulfur Program
We are proposing to prohibit the
production, distribution, and sale or
offer for sale of any fuel for use in any
marine diesel vessels (C1, C2, and C3)
operating in the U.S. ECA that is greater
than 1,000 ppm sulfur. We are also
proposing and requesting comment on
allowing a sulfur limitation of 1,000
ppm for fuel produced, distributed, and
sold or offered for sale for use in C3
marine vessels. To simplify the existing
diesel fuel sulfur program, we are also
proposing to eliminate the 500 ppm LM
diesel fuel standard once the 1,000 ppm
standard becomes effective. Under the
existing diesel sulfur program, 500 ppm
LM diesel fuel can be produced by
transmix processors indefinitely, and
can only be used by locomotives and
marine vessels that do not require 15
ppm. The original intent of allowing for
this fuel was to serve as an outlet for
interface and downgraded diesel fuel
post-2014 that would otherwise not
meet the 15 ppm sulfur standard.
However, we believe that the 1,000 ppm
sulfur ECA marine fuel could now serve
as this outlet. We believe that transmix
generated near the coasts would have
ready access to marine applications, and
transmix generated in the mid-continent
could be shipped via rail to markets on
the coasts, and we request comment on
this.
Elimination of the 500 ppm LM diesel
fuel standard would simplify the diesel
sulfur program such that sulfur could
serve as the distinguishing factor for
fuels available for use after 2014 (the
designated products under the diesel
fuel program would thus be: 15 ppm
motor vehicle, nonroad, locomotive, and
marine (MVNRLM) diesel fuel, heating
oil, and 1,000 ppm ECA marine fuel).
With this proposed approach, beginning
in 2014, only 15 ppm NRLM diesel fuel
could be used in locomotive and C1/C2
marine diesel applications (and 1,000
ppm ECA marine fuel could be used in
any engine on C3 marine vessels).
Further, this would help to streamline
the D&T program as there would no
longer be a need for a fuel marker to
distinguish 500 ppm LM diesel fuel
from heating oil. Below, we discuss the
aspects of D&T that we are proposing to
change, which we believe will greatly
simplify the diesel sulfur program.
(a) Compliance and Implementation
(i) Northeast/Mid-Atlantic Area and the
Fuel Marker
With the proposed elimination of the
500 ppm LM designation in 2014,
parties in the fuel production and
distribution industry would still be
E:\FR\FM\28AUP2.SGM
28AUP2
Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
required to register and designate their
products and adhere to PTD, fuel pump
labeling, and recordkeeping
requirements. But we believe that the
tracking portion of D&T can be
simplified. Currently, annual reporting
is required under § 80.601 for D&T
through June 30, 2015 (the final annual
report is due August 31, 2015). This
final reporting period is to ensure that
heating oil is not being inappropriately
shifted into the 500 ppm LM diesel fuel
pool. However, with the proposed
elimination of this fuel designation, we
request comment on ending D&T annual
reporting in 2014, rather than 2015.
Under such a scenario, the final annual
reporting period would instead be July
1, 2013 through May 31, 2014, with the
report due to EPA on August 31, 2014.
We believe that the proposed
elimination of the 500 ppm LM diesel
fuel designation would also, beginning
June 1, 2014, negate the need for the
heating oil marker and the NE/MA area.
After 2014, the heating oil marker
requirement in the existing diesel sulfur
program is for the sole purpose of
distinguishing heating oil from 500 ppm
LM diesel fuel, to prevent heating oil
from swelling the 500 ppm LM diesel
fuel pool. Also, as there is no marker
requirement for heating oil in the NE/
MA area, the diesel sulfur program
currently does not allow for 500 ppm
LM diesel fuel to be produced,
distributed, or purchased for use in the
NE/MA area after 2012. However, if 500
ppm LM diesel fuel did not exist, there
would no longer be a need for the
heating oil marker; fuel designations
and sulfur level could serve as the
distinguishing factor between the
available fuels (15 ppm MVNRLM diesel
fuel, 1,000 ppm ECA marine fuel, and
heating oil). Further, there would not be
a need for the NE/MA area if there were
no heating oil marker.
(ii) PTDs and Labeling
We are proposing new PTD language
for the 1,000 ppm ECA marine fuel
designation at draft regulation § 80.590.
As stated in draft regulation
§ 80.590(a)(7)(vii), we are proposing that
the following statement be added to
PTDs accompanying 1,000 ppm sulfur
ECA marine fuel: ‘‘1,000 ppm sulfur
(maximum) ECA Marine Fuel. For use
in Category 3 marine vessels only. Not
for use in engines not installed on C3
marine vessels.’’
Appendix V of Annex VI also
includes language that is required on
bunker delivery notes. Compliance
requirements of this action, such as
PTDs, are not intended to supplant or
replace requirements of Annex VI (and
we encourage regulated entities to
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
consult Annex VI to ensure that they are
fully aware of all requirements that
must be met in addition to EPA’s
requirements). However, if a party’s
bunker delivery note also contains the
information required under our
regulations for PTDs, we would
consider the bunker delivery note to
also suffice as a PTD.
We are also proposing new pump
labeling language for the 1,000 ppm
sulfur ECA marine fuel designation at
regulation § 80.574. Diesel fuel pump
labels required under the existing diesel
sulfur regulations must be prominently
displayed in the immediate area of each
pump stand from which diesel fuel is
offered for sale or dispensing. However,
we understand that there may be cases
where it is not feasible to affix a label
to a fuel pump stand due to space
constraints (such as diesel fuel pumps at
marinas) or where there is no pump
stand, thus the current regulations allow
for alternative pump labels with EPA
approval. Previously approved
alternative fuel pump labels have
included the use of permanent placards
in the immediate vicinity of the fuel
pump; we request comment on other
possible alternative labeling schemes for
situations where pump labeling may not
be feasible. As stated in draft regulation
§ 80.574, we are proposing to replace
the 500 ppm LM diesel fuel pump label
language with the following fuel pump
label language for 1,000 ppm sulfur ECA
marine fuel: ‘‘1,000 ppm SULFUR ECA
MARINE FUEL (1,000 ppm Sulfur
Maximum). For use in Category 3
marine vessels only. WARNING—
Federal law prohibits use in any engine
that is not installed on a C3 marine
vessel; use of fuel oil with a sulfur
content greater than 1,000 ppm in the
U.S. Emission Control Area and all U.S.
internal waters is illegal.’’ We also
request comment on whether or not fuel
pumps are (or can be) used to fuel C3
marine vessels; and if they are not used,
if PTDs or some other documentation is
a more appropriate mechanism to
convey the fuel sulfur level to a C3
marine vessel operator.
Under this program, we are also
proposing to eliminate MVNRLM diesel
fuel labeling requirements from EPA’s
regulations. In 2014 and beyond, EPA
will not require ‘‘visible evidence’’ of
red dye in off-road fuels; however this
requirement still exists in IRS’s taxation
regulations to denote that off-road fuels
are untaxed. EPA’s required label for 15
ppm NRLM diesel fuel (instead of one
15 ppm MVNRLM diesel fuel label) is
mainly to denote that 15 ppm NRLM
will be dyed red, while 15 ppm MV
diesel fuel will not. Further, after

fuel available for purchase and/or
distribution will be 15 ppm. We believe
that it is not appropriate for EPA to
retain a labeling requirement for
MVNRLM diesel fuel given the fact that
the red dye provision is no longer EPA’s
requirement. Please note, however, that
if MVNRLM labeling requirements were
removed from EPA’s regulations,
marketers and wholesale purchaserconsumers would still be free to
continue to label their pump stands to
help with consumer awareness.
Labeling will continue to be required for
heating oil and, as proposed above, for
ECA marine fuel.
Additionally, if labeling requirements
for MVNRLM diesel fuel were to be
removed from EPA’s regulations, EPA
would consult with IRS regarding
handling labels in IRS’s regulations at
Title 26 of the Code of Federal
Regulations.
(b) Timing of the Standard
Currently, all refiners and importers
are required to produce all of their
NRLM diesel fuel to meet the 15 ppm
standard beginning June 1, 2014. To
allow transition time for the distribution
system, terminals are allowed until
August 1, 2014 to begin dispensing 15
ppm NRLM diesel fuel, retailers and
wholesale purchaser-consumers are
allowed until October 1, 2014, and endusers are allowed until December 1,
2014. To be consistent with the existing
diesel program, we are proposing to
allow refiners to begin producing 1,000
ppm sulfur ECA marine fuel beginning
June 1, 2014, and downstream parties
would follow the current NRLM
transition schedule (August, October,
and December). We believe that
following the same transition schedule
as the existing diesel sulfur program
would best facilitate the availability of
1,000 ppm ECA marine fuel for
purchase and use by the Annex VI
January 1, 2015 date. We request
comment on the concept of a transition
period of June 1–December 1, 2014 for
the 1,000 ppm sulfur standard.
(2) Alternative Options
We have identified two potential
alternatives to the proposed changes to
the existing diesel fuel sulfur program,
above. We request comment on any
related aspects of these alternative
options, as well as any additional
alternative options.
(a) Creation of Expanded NE/MA Area

sulfur standard is to incorporate the
benefits of this more stringent standard
for fuel used in engines on C3 marine
vessels into our current diesel program

and harmonize the current program
with Annex VI, our intent is to do so
with the least amount of impact on the
existing diesel sulfur program, so we
believe that this rulemaking also
presents us with an opportunity to
simplify the designate and track
requirements.
We request comment on an alternative
to the proposed general program: to
expand the NE/MA area to cover all
coastlines that border the proposed U.S.
ECA. This alternative would keep the
requirements of the diesel sulfur
program largely the same as the existing
program. Further, this option would
allow for 500 ppm LM diesel fuel to
continue to be utilized by the
locomotive industry (and the marine
industry) in the mid-continent (outside
the expanded NE/MA area) and to serve
as an outlet for off-spec and transmix
diesel fuel. As discussed above in
Section IV.B.3, under our current diesel
fuel sulfur program, 500 ppm LM diesel
fuel cannot be used in the NE/MA area
(or Alaska) after 2012. Under the
‘‘expanded NE/MA’’ area option,
designate and track would be simplified
in the expanded NE/MA area as the only
distillate fuels available would be 15
ppm MVNRLM diesel fuel, heating oil,
and 1,000 ppm ECA marine fuel. The
reduction in types of fuel available for
use in this area would also allow for
sulfur level to serve as the
distinguishing factor, and no additional
markers or dyes would be necessary to
differentiate fuels in this area.
The creation of an expanded NE/MA
area, however, would mean that an
additional mechanism to distinguish
500 ppm LM diesel fuel from 1,000 ppm
ECA marine fuel would still be needed
in non-NE/MA areas.
We request comment on the creation
of an expanded NE/MA area.

outlet for off-spec and transmix diesel
fuel. However, this option would not
serve to streamline D&T, and 500 ppm
LM diesel fuel would not necessarily be
needed along the coastlines (as 1,000
ppm sulfur fuel would be available for
use by C3 marine vessels). We request
comment on the option of retaining the
500 ppm LM diesel fuel standard
nationwide along with the proposed
1,000 ppm ECA marine fuel sulfur
standard.
We request comment on the proposed
program and alternative options, the
proposed prohibition on the sale of fuel
above 1,000 ppm sulfur for use in all
marine vessels operating in the U.S.
ECA and U.S. internal waters, and any
related compliance aspects.

Description of change
(b) Retention of 500 ppm LM Diesel
Fuel Standard
Another alternative to the option of
replacing the 500 ppm LM diesel fuel
standard with the 1,000 ppm sulfur
standard would be to retain the 500
ppm LM diesel fuel standard such that
both 500 ppm LM diesel fuel and 1,000
ppm ECA marine fuel would be
available. Under such an option, sulfur
would not be able to serve as the
distinguishing factor to maintain
segregation of 1,000 ppm fuel from other
EPA distillate categories. The fuel
marker would still be needed to
distinguish 500 ppm LM from heating
oil.
This option would allow for 500 ppm
LM diesel fuel to still be utilized by the
locomotive and marine industries (for

V. Emission Control Areas for U.S.
Coasts
The proposed Clean Air Act standards
described above are part of a
coordinated strategy for ensuring that all
ships that affect U.S. air quality will be
required to meet stringent NOX and fuel
sulfur requirements. Another
component of this strategy consists of
pursuing ECA designation for U.S. and
Canadian coasts in accordance with
Annex VI of MARPOL. ECA designation
will ensure that all ships, foreignflagged and domestic, are required to
meet stringent NOX and fuel sulfur
requirements while operating within
200 nautical miles of most U.S. coasts.
This section describes what an ECA is,
the process for obtaining ECA
designation at the International
Maritime Organization, and summarizes
the U.S. and Canadian proposal for an
amendment to MARPOL Annex VI
designating most U.S. and Canadian
coasts as an ECA (referred to as the
‘‘U.S./Canada ECA’’ or the ‘‘North
American ECA’’), submitted to IMO on
March 27, 2009.97 We also discuss how
emissions from foreign OGV may be
covered should approval of the U.S.
ECA be delayed.
A. What is an ECA?
(1) What Emissions Standards Apply in
an ECA?
MARPOL Annex VI contains
international standards to control air
emissions from ships. The NOX and
SOX/PM programs each contain two sets
of standards. The global standards for
the sulfur content of fuel and NOX
emissions from engines apply to ships at
all times. In recognition that some areas
may require further control, Annex VI
also contains more stringent NOX and
SOX/PM geographic-based standards
that apply to ships operating in
designated Emission Control Areas.
97 Proposal to Designate an Emission Control
Area for Nitrogen Oxides, Sulphur Oxides and
Particulate Matter, Submitted by the United States
and Canada. IMO Document MEPC59/6/5, 27
March, 2009. A copy of this document can be found

Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
The current global fuel sulfur (S) limit
is 45,000 ppm98 S and will tighten to
35,000 ppm S in 2012. Depending on a
2018 fuel availability review, the
MARPOL Annex VI global fuel sulfur
limit will be further reduced to 5,000
ppm S as early as 2020. In contrast,
ships operating in designated ECAs are
subject to a fuel sulfur limit of 15,000
ppm S. The ECA limit is reduced to
10,000 ppm S in March 2010 and 1,000
ppm S in 2015. In addition, Tier 3 NOX
standards will apply to new engines
operating in ECAs beginning in 2016.
These Tier 3 NOX standards represent
an 80% reduction in NOX beyond
current Tier 1 standards and are
anticipated to require the use of
aftertreatment technology such as SCR.
We are proposing to adopt similar Tier
3 standards as part of our Clean Air Act
program (see Section III).
There are currently two ECAs in effect
today, exclusively controlling SOX; thus
they are called Sulfur Emission Control
Areas, or SECAs. The first SECA was
designated to control the emissions of
SOX in the Baltic Sea area and entered
into force in May 2005. The second
SECA was designated to control the
emissions of SOX in the North Sea area
and entered into force in November
2006.
(2) What is the Process for Obtaining
ECA Designation?
A proposal to amend Annex VI to
designate an ECA can be submitted by
a party to Annex VI. A party is a country
that ratified Annex VI. The proposal for
amendment must be approved by the
Parties to MARPOL Annex VI; this
would take place at a meeting of the
Marine Environment Protection
Committee (MEPC). The U.S. deposited
its Instrument of Ratification with the
IMO on October 8, 2008. Annex VI
entered into force for the U.S. on
January 8, 2009, making the U.S. eligible
to apply for an ECA.
The criteria and procedures for ECA
designation are set out in Appendix III
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
98 Note that MARPOL Annex VI expresses these
standards in units of % (m/m) sulfur. 10,000 ppm
S equals 1 percent S.
VerDate Nov<24>2008

Jkt 217001
to MARPOL Annex VI. A proposal to
designate an ECA must demonstrate a
need to prevent, reduce, and control
emissions of SOX, PM, and/or NOX from
ships operating in that area. The specific
criteria are summarized below:
• A delineation of the proposed area
of application;
• A description of the areas at risk on
land and at sea, from the impacts of ship
emissions;
• An assessment of the contribution
of ships to ambient concentrations of air
pollution or to
• Adverse environmental impacts;
• Relevant information pertaining to
the meteorological conditions in the
proposed area of
• Application to the human
populations and environmental areas at
risk;
• Description of ship traffic in the
proposed ECA;
• Description of the control measures
taken by the proposing Party or Parties;
• Relative costs of reducing emissions
from ships compared with land-based
controls; and
• An assessment of the economic
impacts on shipping engaged in
international trade.
An amendment to designate an ECA
must be adopted by the Parties to Annex
VI, as an amendment to Annex VI.
Assuming the USG proposal to amend
Annex VI is considered at MEPC 59, the
earliest possible adoption date is the
following MEPC meeting, MEPC 60,
which is anticipated to take place in
March 2010. Given the MARPOL
amendment acceptance process and the
lead time specified in the regulations,
an ECA adopted on this timeline could
be expected to enter into force as early
as August 2012.
B. U.S. Emission Control Area
Designation
EPA worked with the U.S. Coast
Guard, State Department, the National
Oceanic and Atmospheric
Administration and other agencies to
develop the analysis supporting ECA
designation for U.S. coasts contained in
the U.S. and Canadian submittal to IMO.
PO 00000
Frm 00029
Fmt 4701
Sfmt 4702
44469
In addition, we collaborated with
Environment Canada. As a result, the
proposal for ECA designation that was
submitted to IMO was for a combined
U.S./Canada ECA submission. This
approach has several advantages. First,
the emission reductions within a
Canadian ECA will lead to air quality
improvements in the U.S. Second, a
joint ECA helps minimize any
competitive issues between U.S. and
Canadian ports, such as in the Puget
Sound area, that could arise from ECA
standards. Third, IMO encourages a
joint submittal where there is a common
interest in emission reductions on
neighboring waters.
(1) What Areas Would Be Covered in a
U.S./Canada ECA?
The area included in the U.S. and
Canadian submittal to IMO for ECA
designation generally extends 200
nautical miles from the coastal baseline,
except where this distance goes beyond
the Exclusive Economic Zones (EEZ) of
the U.S. and Canada, in which case the
ECA would be limited by the boundary
of the applicable EEZ. This area would
include the Pacific Coast, the Atlantic/
Gulf Coast and the Southeastern
Hawaiian Islands. On the Pacific Coast,
the ECA would be bounded in the north
such that it includes the approaches
into Anchorage, Alaska, but not the
Aleutian Islands or points north. It
would continue contiguously to the
south including the Pacific coasts of
Canada and the U.S., with its
southernmost boundary at the point
where California meets the border with
Mexico. In the Atlantic/Gulf Coast, the
ECA would be bounded in the west by
the border of Texas with Mexico and
continue contiguously to the east
around the peninsula of Florida and
north up the Atlantic coasts of the U.S.
and Canada and would be bounded in
the north by the 60th North parallel.
The Southeastern Hawaiian Islands that
were included in the ECA submittal are
Hawaii, Maui, Oahu, Molokai, Niihau,
Kauai, Lanai, and Kahoolawe.

proposal for ECA designation of these
areas.
(2) What Analyses Were Performed in
Support of a U.S./Canada ECA?
We performed a comprehensive
analysis to estimate the degree of human
health risk and environmental
degradation that is posed by air
emissions from ships operating in their
ports and along our coasts. To evaluate
the risk to human populations, state-ofthe-art assessment tools were used to
apply widely accepted methods with
advanced computer modeling
techniques. The analyses incorporated
detailed ship traffic data, the most
recent emissions estimates, detailed
observed meteorological data, current
scientific understanding of exhaust
plume behavior (both physical
dispersion and photochemical reaction)
and the latest epidemiologic databases
of health effects attributable to pollutant
exposure levels to estimate the current
impacts of shipping on human health
and the environment. In addition,
sulfate and nitrate deposition modeling
was performed to assess the impacts of
nitrogen nutrient loading and
acidification on U.S. ecosystems.
Two contrasting future scenarios were
evaluated: one in which ships continue
to operate with current emissions
performance while operating in the
specified area, and one in which ships
comply with ECA standards. The
analysis demonstrated that ECA
designation for U.S. coasts could save
thousands of lives each year, relieve
millions of acute respiratory symptoms,
and benefit many of the most sensitive
ecosystems. This analysis is consistent
with, and incorporated in, the benefits
estimates presented in Section VIII.

C. Technological Approaches To
Comply With ECA Standards
When operating within the ECA, all
ships would have to comply with the
0.1% fuel sulfur limit and vessels built
after December 31, 2015 would have to
comply with the Tier 3 NOX limits
described above. This section describes
how ships would comply with these
requirements.
(1) How Will Ships Comply With the
ECA NOX Standards?
Ships constructed beginning in 2016
will have to comply with the MARPOL
Annex VI Tier III NOX limits. These are
equivalent to the Tier 3 NOX limits we
are proposing in this action under our
Clean Air Act authority. These
standards are geographic in nature, in
that they apply to any vessel built
beginning in 2016 while it is operating
in an ECA. Once a U.S./Canada ECA is
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
designated through amendment to
MARPOL Annex VI, the requirements
will be enforceable for most vessels
through the Act to Prevent Pollution
from Ships (see Section VI.B).
As explained in Section III, we
anticipate that SCR would be the most
likely approach to meet these NOX
limits. When operating in the ECA, SCR
units would be active, meaning that
urea would be injected into the exhaust
to facilitate catalytic reduction of NOX
emissions. When outside of the ECA,
the unit would likely be inactive,
meaning that urea would not be injected
into the exhaust. When the SCR unit is
inactive, the exhaust flow could either
continue to pass through the SCR unit
or be diverted around the catalyst.
Under the MARPOL NOX Technical
Code, a means for monitoring the use of
urea must be provided which must
include ‘‘sufficient information to allow
a ready means of demonstrating that the
consumption of such additional
substances is consistent with achieving
compliance with the applicable NOX
limit.’’ In addition, where an NOX
reducing device, such as SCR, is used,
one of the options for providing
verification of compliance with the NOX
standard is through direct measurement
and monitoring of NOX emissions.
When operating in an ECA, as
discussed below, it is anticipated that
vessels will operate on lower sulfur fuel
than outside the ECA. Therefore, lower
sulfur fuel will primarily be used when
the SCR unit is active. However, ship
operators may use an exhaust gas
scrubber as an alternative to lower
sulfur fuel to meet the SOX/PM ECA
requirement. In this case, the SCR unit
would likely be optimized for operation
on higher sulfur fuel, with the SOX
scrubber situated downstream of the
SCR unit.
(2) How Will Ships Comply With the
ECA Fuel Sulfur Standards?
As discussed above, the MARPOL
Annex VI fuel sulfur limit for ships
operating in an ECA is 15,000 ppm
today and reduces to 10,000 ppm in
March 2010 and further to 1,000 ppm in
2015. We anticipate that the 1,000 ppm
fuel sulfur limit, beginning in 2015, will
likely result in the use of distillate fuel
for operation in ECAs. This would
require the vessel to switch from a
higher sulfur fuel to 1,000 ppm S fuel
before entering the ECA. The practical
implications of fuel switching are
discussed below. As an alternative to
operating on lower sulfur fuel, an
exhaust gas cleaning device may be
used to remove sulfur from the exhaust.
These devices, which are colloquially
PO 00000
Frm 00031
Fmt 4701
Sfmt 4702
44471
known as SOX scrubbers, are also
discussed below.
(a) Fuel Switching
Currently, the majority of ocean-going
vessels use residual fuel (also called
HFO or IFO) in their main propulsion
engines, as this fuel is relatively
inexpensive and has a good energy
density. This fuel is relatively dense
(‘heavy’) and is created as a refining byproduct from typical petroleum
distillation. Residual fuels typically are
composed of heavy, residuum
hydrocarbons and can contain various
contaminants such as heavy metals,
water and sulfur compounds. It is these
sulfur compounds that cause the SOX
emissions when the fuel is combusted.
If the vessel does not employ the use of
a sulfur scrubber or other technology, it
will most likely operate on a marine
distillate fuel while in an ECA in order
to meet the sulfur emission
requirements.
The sulfur in marine fuel is primarily
emitted as SO2; however, a small
fraction (about 2 percent) is converted to
SO3. SO3 almost immediately forms
sulfate and is emitted as direct PM by
the engine. Consequently, emissions of
SO2 and sulfate PM are very high for
engines operating on residual fuel.
Switching from high sulfur residual fuel
to lower sulfur distillate fuel results in
large reductions in SO2 and sulfate PM
emissions. In addition to high sulfur
levels, residual fuel contains relatively
high concentrations of low volatility,
high molecular weight organic
compounds and metals. Organic
compounds that contribute to PM can be
present either as a nucleation aerosol or
as a material adsorbed on the surfaces
of agglomerated elemental carbon soot
particles and metallic ash particles. The
sulfuric acid aerosol in the exhaust
provides a nucleus for agglomeration of
organic compounds. Operation on
higher volatility distillate fuel reduces
both nucleation and adsorption of
organic compounds into particulate
matter. Therefore, in addition to direct
sulfate PM reductions, switching from
residual fuel to distillate fuel reduces
organic PM and metallic ash particles in
the exhaust.
In the majority of vessels which
operate on residual fuel, marine
distillate fuel is still used for operation
during routine maintenance, prior to
and immediately after engine shutdown, or in emergencies. Standard
procedures today have been established
to ensure that this operational fuel
switchover is performed safely and
efficiently. Mainly, in order for the
vessel to completely switch between
residual and distillate fuel, the fuel
E:\FR\FM\28AUP2.SGM
28AUP2
44472
Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
pumps and wetted lines will need to be
completely purged by the new fuel to
ensure that the ship is burning the
correct fuel for the area. This purging
will vary from ship to ship due to
engine capacity, design, operation, and
efficiency. Provided the ship has
separate service tanks for distillate and
residual fuel (most, if not all, vessels
do), fuel switching time should be
limited only by maximum allowable
rate of fuel temperature change.
Additionally, for a longer operation
period such as would occur while in an
ECA, we investigated several other fuel
switching topics to ensure that vessels
would not have long-term issues from
operating on the marine distillate fuels.
Marine distillate fuels are similar in
composition and structure to other
petroleum-based middle distillate fuels
such as diesel and No. 2 heating oil, but
they have a much lower allowable
sulfur content than residual fuels. This
lower sulfur content means that by
combusting marine distillate fuel in
their propulsion engines, vessels
operating within the ECA would meet
the stricter SOX requirements. However,
sulfur content is not the only difference
between the marine residual and
distillate fuels; they also have different
densities, viscosities, and other
specification limits.
The maritime industry has analyzed
the differences between residual and
distillate fuel compositions to address
any potential issues that could arise
from switching operation of a C3 engine
from residual fuel to distillate fuel. The
results from this research has evolved
into routine operational switching
procedures that ensure a safe and
efficient way for the C3 engines to
switch operation between the residual
and distillate fuels. A brief summary of
the fuel differences, as well as any
potential issues and their usual
solutions, is presented below.
(i) Fuel Density
Due to its chemical composition,
residual fuel has a slightly higher
density than marine distillates. Using a
less dense fuel could affect the ballast
of a ship at sea and would have to
require compensation. Therefore, when
beginning to operate on the distillate
fuel, the vessel operator would have to
pay attention to the vessel’s ballast and
may have to compensate for any
changes that may occur. We anticipate
that these procedures would be similar
to operating the vessel with partiallyfull fuel tanks.
Another consideration when
switching to a lower density fuel is the
change in volumetric energy content.
Distillate fuel has a lower energy
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
density content on a per gallon basis
when compared to the residual fuel;
however, per ton, distillate fuel’s energy
density is larger than the residual fuel.
This means that when switching from
residual fuel to distillate fuel, if the
vessel’s tanks are volumetrically limited
(i.e., the tanks can only hold a set
quantity of fuel gallons), the distance a
vessel can travel on the distillate fuel
may be slightly shorter than the distance
the vessel could travel on the residual
fuel due to the lower volumetric energy
content of distillate fuel, which could
require compensation. This distance
reduction would be approximately 5%
and would only be of concern while the
vessel was operating on the distillate
fuel (i.e., while in the U.S. ECA) as the
majority of the time the vessel will be
operating on the residual fuel. However,
if the vessel is limited by weight, the
higher energy content per ton of fuel
would provide an operational
advantage.
(ii) Kinematic Viscosity
Residual fuel’s kinematic viscosity is
much higher than marine distillate
fuel’s viscosity. Viscosity is the
‘thickness’ of the fuel. If this parameter
is lowered from the typical value used
within a pump, some issues could arise.
If a distillate fuel is used in a system
that typically operates on residual fuel,
the decrease in viscosity could cause
problems with high-pressure fuel
injection pumps due to the increased
potential for internal leakage of the
thinner fuel through the clearances in
the pumping elements. Internal leakage
is part of the design of a fuel pump and
is used in part to lubricate the pumping
elements. However, if this leakage rate
is too high, the fuel pump could
produce less than optimal fuel injection
pressures. If the distillate fuel’s lower
viscosity becomes an issue, it is possible
to cool the fuel and increase the
viscosity above 2 centistokes, which is
how most vessels operate today during
routine fuel switchovers.
(iii) Flash Point
Flash point is the temperature at
which the vapors off the fuel ignite with
an outside ignition source. This can be
a safety concern if the owner/operator
uses an onroad diesel fuel rather than a
designated ‘marine distillate’ fuel for
operation because marine fuels have a
specified minimum flash point of 60 °F
(15.6 °C) to ensure onboard safety,
whereas onroad diesel has a minimum
specified flash point of 52 °F (11.1 °C).
However, since most distillate fuels are
created in the same fashion, typical
flash points of onroad diesel are above
60 °F (15.6 °C), and would meet the
PO 00000
Frm 00032
Fmt 4701
Sfmt 4702
marine fuel specification for this
property. If the flash point of the fuel
being used on-board the vessel becomes
a concern, the operator/bunker supplier
would have to ensure that the vessel is
obtaining fuel with a minimum flash
point of 60 °F (15.6 °C) via the bunker
delivery note or through fuel testing.
(iv) Lubricity
Lubricity is the ability of the fuel to
lubricate the engine/pump during
operation. Fuels with higher viscosity
and high sulfur content tend to have
very good lubricity without the use of
specific lubricity-improving additives.
Refining processes that lower fuel sulfur
levels and their viscosities can also
remove some of the naturally-occurring
lubricating compounds. Severe
hydrotreating of fuel to obtain ultra-low
sulfur levels can result in poor fuel
lubricity. Therefore, refineries
commonly add lubricity improvers to
ultra-low sulfur diesel. This will most
likely become a concern when very low
levels of sulfur are present in the fuel
and/or the fuel has been hydrotreated to
reduce sulfur, e.g., if ultra-low sulfur
highway diesel (ULSD) is used in the
engine. Several groups have conducted
studies on this subject, and for some
systems where fuel lubricity has become
an issue, lubricity additives can be
utilized or the owner/operator can
install a lubricating system for the fuel
pump.
(v) Lube Oil
Lube oils are used to neutralize acids
formed in combustion, most commonly
sulfuric acids created from sulfur in the
fuel. The quantity of acid-neutralizing
additives in lube oil should match the
total sulfur content of the fuel. If
excessive amounts of these additives are
used, they may create deposits on
engine components. Marine engine
manufacturers have recommended that
lube oil only needs to be adjusted if the
fuel is switched for more than one week,
but the oil feed rate may need to be
reduced as well as engine operating
power. Additional research has been
conducted in this area and several oil
companies have been working to create
a lubricating oil that would be
compatible with several different types
of fuel.
(vi) Asphaltenes
Asphaltenes are heavy, non-volatile,
aromatic compounds which are
contained naturally in some types of
crude oil. Asphaltenes may precipitate
out of the fuel solution when a fuel rich
in carbon disulfide, such as residual
fuel, is mixed with a lighter
hydrocarbon fuel, such as n-pentane or
E:\FR\FM\28AUP2.SGM

Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
n-heptane found in some distillate fuels.
When these heavy aromatic compounds
fall out of the fuel solution, they can
clog filters, create deposition along the
fuel lines/combustion chamber, seize
the fuel injection pump, or cause other
system troubles. This risk can be
minimized through onboard test kits
and by purchasing distillate and
residual fuel from the same refiner.
However, according to the California Air
Resources Board, the formation of
asphaltenes is not seen as an issue based
on data from previous maritime rules.
As can be seen, if vessel operators
choose to operate on marine distillate
fuel while in the ECA, some prudence
is required. However, as described
above, any issues that could arise with
switching between residual and
distillate fuel are minimal and can be
addressed through changes to operating
procedures. To conduct a successful
switchover between the residual and
marine distillate fuels, vessel operators
will need to keep the above issues in
mind and follow the engine
manufacturer’s standard fuel switching
procedure.
(b) SOX Scrubber
Annex VI allows for alternative
compliance strategies in including the
use of exhaust gas cleaning systems
(EGCS). EGCS systems used today for
sulfur control are commonly known as
SOX scrubbers. This section describes
the technological feasibility of scrubbers
and how scrubbers may be used to
achieve equivalent emission reductions
as fuel switching.
SOX scrubbers are capable of
removing up to 95 percent of SOX from
ship exhaust using the ability of
seawater to absorb SOX. SOX scrubbers
have been widely used in stationary
source applications, where they are a
well-established SOX reduction
technology. In these applications, lime
or caustic soda are typically used to
neutralize the sulfuric acid in the
washwater. While SOX scrubbers are not
widely used on ocean-going vessels,
there have been prototype installations
to demonstrate their viability in this
application such as the Krystallon
systems installed on the P&O ferry Pride
of Kent and the Holland America Line
cruise ship the ms Zaandam. These
demonstrations have shown scrubbers
can replace and fit into the space
occupied by the exhaust silencer units
and can work well in marine
applications.
There are two main scrubber
technologies. The first is an open-loop
design which uses seawater as exhaust
washwater and discharges the treated
washwater back to the sea. Such open-
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
loop designs are also referred to as
seawater scrubbers. In a seawater
scrubber, the exhaust gases are brought
into contact with seawater, either
through spraying seawater into the
exhaust stream or routing the exhaust
gases through a water bath. The SO2 in
the exhaust reacts with oxygen to
produce sulfur trioxide which then
reacts with water to form sulfuric acid.
The sulfuric acid in the water then
reacts with carbonate and other salts in
the seawater to form sulfates which may
be removed from the exhaust. The
washwater is then treated to remove
solids and raise the pH prior to
discharge back to the sea. The solids are
collected as sludge and held for proper
disposal ashore.
A second type of SOX scrubber which
uses a closed-loop design is also feasible
for use on marine vessels. In a closed
loop system, fresh water is used as
washwater, and caustic soda is injected
into the washwater to neutralize the
sulfur in the exhaust. A small portion of
the washwater is bled off and treated to
remove sludge, which is held and
disposed of at port, as with the openloop design. The treated effluent is held
onboard or discharged at open sea.
Additional fresh water is added to the
system as needed. While this design is
not completely closed-loop, it can be
operated in zero discharge mode for
periods of time.
Exhaust gas scrubbers can achieve
reductions in particulate matter as well.
By removing sulfur from the exhaust,
the scrubber removes most of the direct
sulfate PM. Sulfates are a large portion
of the PM from ships operating on high
sulfur fuels. By reducing the SOX
emissions, the scrubber will also control
much of the secondary PM formed in
the atmosphere from SOX emissions.
However, simply mixing alkaline water
in the exhaust does not necessarily
remove much of the carbonaceous PM,
ash, or metals in the exhaust. While SO2
associates with the washwater, particles
can only be washed out of the exhaust
through direct contact with the water. In
simple scrubber designs, much of the
mass of particles can reside in gas
bubbles and escape out the exhaust.
Manufacturers have been improving
their scrubber designs to address
carbonaceous soot and other fine
particles. Finer water sprays, longer
mixing times, and turbulent action
would be expected to directionally
reduce PM emissions through contact
impactions. One scrubber design uses
an electric charge on the water to attract
particles in the exhaust to the water. In
another design, demisters are used that
help effectively wash out PM from the
exhaust stream. In either of these
PO 00000
Frm 00033
Fmt 4701
Sfmt 4702
44473
designs, however, the systems would be
effective at removing SO2 from the
exhaust even if the additional hardware
needed for non-sulfate PM reduction
were not used.
Annex VI does not present specific
exhaust gas limits that are deemed to be
equivalent to the primary standard of
operating on lower sulfur fuel. Prior to
the recent amendments to Annex VI,
Regulation 13 included a limit of 6 g/
kW-hr SO2 as an alternative to the
15,000 ppm sulfur limit for sulfur
emission control areas. Under the
amended requirements, the specific SO2
limit was removed and more general
language on alternative approaches was
included. Specifically, Regulation 4 of
MARPOL Annex VI now states ‘‘The
Administration of a Party may allow any
fitting, material, appliance or apparatus
to be fitted in a ship or other
procedures, alternative fuel oils, or
compliance methods used as a
alternative to that required by this
Annex if such fitting, material,
appliance or apparatus or other
procedures, alternative fuel oils, or
compliance methods are at least as
effective in terms of emissions
reductions as that required by this
Annex, including any of the standards
set forth in regulations 13 and 14.’’
IMO is developing guidelines for the
use of exhaust gas cleaning devices such
as SOX scrubbers as an alternative to
operating on lower sulfur fuel.99 These
draft guidelines include a table of SO2
limits intended to correspond with
various fuel sulfur levels. Based on the
methodology that was used to determine
the SO2 limit of 6.0 g/kW-hr for existing
ECAs, the corresponding limit is 0.4 g/
kW-hr SO2 for a 1,000 ppm fuel sulfur
limit. This limit is based on an assumed
fuel consumption rate of 200 g/kW-hr
and the assumption that all sulfur in the
fuel is converted to SO2 in the exhaust.
The draft IMO guidelines also allow for
an alternative approach of basing the
limit on a ratio of SO2 to CO2. This has
the advantage of being easier to measure
during in-use monitoring. In addition,
this ratio holds more constant at lower
loads than a brake-specific limit, which
would approach infinity as power
approaches zero. For the existing 15,000
ppm fuel sulfur limit in ECAs, a SO2
(ppm)/CO2(%) limit of 65 was
developed. The equivalent limit for a

Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
1,000 ppm fuel sulfur level is 4.0 SO2
(ppm)/CO2(%).
Scrubbers are effective at reducing
SO2 emissions and sulfate PM emissions
from the exhaust. However, as discussed
above, the effectiveness of the scrubber
at removing PM emissions other than
sulfates is dependent on the scrubber
design. In addition to sulfate PM
reductions, switching from residual fuel
to distillate fuel results in reductions in
organic PM and metallic ash particles in
the exhaust. As such, consideration
should be given to non-sulfate PM when
making the determination that using a
given ECGS design is ‘‘at least as
effective’’ as operating on lower sulfur
fuel to control PM emissions.
We would not consider an exhaust gas
scrubber to be an acceptable control
strategy for reducing NOX emissions. In
a typical diesel exhaust gas mixture,
NOX is composed of roughly 5–10%
NO2, with the majority of the remainder
in the form of NO. NO2 is soluble in
water, and therefore may be removed by
the water in the scrubber. It is possible
to treat the exhaust upstream of the
scrubber to convert more of the NOX to
NO2, thereby facilitating the use of a
scrubber to remove NO2. However, we
are concerned that this would add to
nitrogen loading of the water in which
the ship is operating. As discussed in
Section II.B.1, nitrogen loading can lead
to serious water quality impacts. The
issue of NOX scrubbing is addressed in
the draft IMO EGCS guidelines by
limiting the amount of NOX that may be
removed by the scrubber.
Water-soluble components of the
exhaust gas such as SO2, SO3, and NO2
form sulfates and nitrates that are
dissolved into the discharge water.
Scrubber washwater also includes
suspended solids, heavy metals,
hydrocarbons and polycyclic aromatic
hydrocarbons (PAH). Before the
scrubber water is discharged, there are
several approaches that may be used to
process the scrubber water to remove
solid particles. Heavier particles may be
trapped in a settling or sludge tank for
disposal. The removal process may
include cyclone technology similar to
that used to separate water from
residual fuel prior to delivery to the
engine. However, depending on particle
size distribution and particle density,
settling tanks and hydrodynamic
separation may not effectively remove
all suspended solids. Other approaches
include filtration and flocculation
techniques. Flocculation, which is used
in many waste water treatment plants,
refers to adding a chemical agent to the
water that will cause the fine particles
to aggregate so that they may be filtered
out. Sludge separated from the scrubber

water would be stored on board until it
is disposed of at proper facilities.
The draft IMO guidelines for the use
of exhaust gas cleaning devices such as
SOX scrubbers include recommended
monitoring and water discharge
practices. The washwater should be
continuously monitored for pH, PAHs
and turbidity. Further, the IMO
guidance include specifications for
these same items, as well as nitrate
content when washwater is discharged
in ports, harbors or estuaries. Finally,
the IMO guidance recommends that
washwater residue (sludge) be delivered
ashore to adequate reception facilities
and not discharged to the sea or burned
on board. Also note that any discharges
directly into waters of the United States
may be subject to the Clean Water Act
or other U.S. regulation.
D. ECA Designation and ForeignFlagged Vessels
In our previous marine diesel engine
rulemakings, EPA did not extend our
Clean Air Act standards to engines on
vessels flagged by other countries. In
our 2003 rule, many states and localities
expressed concern about the high levels
of emissions from ocean-going vessels.
We examined our position and
concluded that no change was necessary
at that time because the Tier 1 standards
we adopted for Category 3 engines on
U.S. vessels were the same as those
contained in MARPOL Annex VI. We
indicated we would re-examine this
issue in our current rulemaking and
would also review the progress made by
the international community toward the
adoption of new more stringent
international standards that reflect the
application of advanced emission
control technologies.
We received comments from a broad
range of interested parties on the
Advance Notice of Proposed
Rulemaking (ANPRM) for this
rulemaking. Generally, these
commenters remain concerned about
the contribution of ocean-going vessels
to their air quality. Many took the
position that EPA should cover engines
on foreign-flagged OGV under Clean Air
Act section 213 since they account for
the vast majority of OGV emissions in
the United States and because of their
perception, at the time these comments
were submitted, that the international
process to set stringent standards was
stalled.
In this section, we provide
background on EPA’s past statements
with regard to the application of our
Clean Air Act section 213 standards to
engines on foreign-flagged vessels, and
summarize comments we received on
this issue in response to our ANPRM.
PO 00000
Frm 00034
Fmt 4701
Sfmt 4702
Because the NOX standards adopted in
the amendments to Annex VI are
comparable in stringency and timing to
our proposed CAA NOX standards, we
do not believe it is necessary to extend
our Clean Air Act Tier 2 and 3 standards
to engines on foreign-flagged vessels at
this time. Therefore, this proposal does
not seek to resolve the issue of whether
section 213 of the Act allows us to set
standards for engines on foreign-flagged
vessels. However, as further explained
below, our decision rests on the timely
adoption of an amendment to Annex VI
designating the U.S. coastal waters as an
ECA, since the most stringent of the
NOX standards will be applicable in
such areas. If the amendment
designating a U.S. ECA is not timely
adopted by the Parties to IMO, we will
revisit this issue.
We request comments on all aspects
of this discussion.
(1) What Is EPA’s Current Approach for
Engines on Foreign-Flagged Vessels?
Section 213 of the Clean Air Act (42
U.S.C. 7547) authorizes regulation of
‘‘new nonroad engine[s]’’ and ‘‘new
nonroad vehicle[s].’’ Because Title II of
the Clean Air Act does not define either
‘‘new nonroad engine’’ or ‘‘new nonroad
vehicle,’’ our early interpretations of
these terms with regard to our other
nonroad programs were reasonably
modeled after the statutory definitions
of ‘‘new motor vehicle engine’’ and
‘‘new motor vehicle’’ found in section
216(3) of the CAA.100 Those early
interpretations focused on engines and
vehicles freshly built or imported.
Similarly, in our first phase of marine
diesel emission standards (our 1999
rule), we modeled our definitions of
‘‘new’’ marine engine and vessel after
the existing ‘‘new nonroad engine’’ and
‘‘new nonroad vehicle’’ regulatory
definitions.101 We also referred to
Department of the Treasury rulings on
the meaning of ‘‘import’’ for customs
purposes.102 Specifically, Treasury
rulings for marine engines and vessels
include as imports only those marine
engines and vessels intended to remain
in the United States permanently.

vessels were only entering U.S. ports
temporarily, with no intention to remain
permanently, we declined to treat those
engines and vessels as imported and,
thus, we determined that these engines
are not ‘‘new’’ marine engines or vessels
for purposes of section 213 of the CAA.
Therefore, in that first rulemaking for
diesel marine engines, we did not apply
the CAA program to engines on foreignflagged vessels.
In our subsequent rulemaking to
establish Clean Air Act emission
standards for Category 3 engines,103 we
re-examined this background to reconsider the issue of whether engines
on foreign-flagged vessels should be
included within the scope of our Clean
Air Act standards. Because the NOX
standards we adopted in that rule were
near-term standards that were
equivalent to the then-MARPOL Annex
I NOX standards, and because we
adopted a regulatory deadline to
consider an additional tier of NOX
standards (which are the subject of the
current rulemaking), we deferred
making a decision on whether we have
the discretion to set standards for such
engines until the present rulemaking.
We decided that even if we have the
discretion to interpret ‘‘new marine
engine’’ to include engines on foreignflagged vessels, it would be appropriate
not to exercise such discretion at that
time since the near-term standards that
we would be adopting in that rule
already applied to foreign-flagged
vessels through Annex VI. We explained
that foreign-flagged vessels were
expected to comply with the current
MARPOL standards whether or not they
were also subject to the equivalent
Clean Air Act standards and,
consequently, no significant emission
reductions would be achieved by
treating foreign-flagged vessels as ‘‘new’’
for purposes of the near-term standards
in that final rule. However, we also
indicated that we would consider, in the
subsequent rulemaking, whether we
need to resolve under what
circumstances we may or should define
new nonroad engine and vessel to
include foreign-flagged engines and
vessels. As part of that determination,
we indicated we would also assess the
progress made by the international
community toward adopting new more
stringent international consensus
standards that reflect advanced
emission-control technologies.

Accordingly, we raised this issue in
our 2007 ANPRM,104 indicating that we
would evaluate whether we should redefine new nonroad engines and vessels
to include foreign-flagged engines and
vessels. Likewise, we indicated that as
part of that evaluation, we would also
assess the progress made by the
international community toward the
adoption of new more stringent
international standards that reflect
advanced emission-control
technologies.
(2) Is EPA Proposing To Change the
Current Approach to Engines on
Foreign-Flagged Vessels?
Since the ANPRM was published, the
International Maritime Organization
adopted amendments to MARPOL
Annex VI. These amendments, adopted
in October 2008, contain stringent new
tiers of NOX emission limits for marine
diesel engines as well as new fuel sulfur
limits.105 These requirements are
applicable in the United States to both
domestic and foreign-flagged vessels
through operation of the Act to Prevent
Pollution from Ships (APPS), as
amended in 2008.106 Amendments to
the Act to Prevent Pollution from Ships
were adopted in 2008 specifically to
provide the statutory mechanism to
enforce the Annex VI requirements on
domestic and foreign-flagged vessels
and to enforce the ECA requirements
once a U.S. ECA is designated under
Annex VI.
The most stringent of the new Annex
VI standards requires engines to meet
Tier III NOX standards. Under the
Annex, these requirements would apply
in designated ECAs. At the time the
amendments were adopted, countries
were invited to propose areas for ECA
designation so that the full benefit of
these technology-forcing standards
could be realized by areas that
demonstrate a need for them. As
explained above, the United States and
Canada recently submitted a proposal to
amend MARPOL Annex VI to designate
U.S. and Canadian coastal areas as an
ECA. Due to the human health and
welfare needs for these controls as
documented in the ECA application, we
expect that the Parties to Annex VI will
adopt this amendment at the 60th

Session of the Marine Environment
Protection Committee (MEPC), to be
held in March 2010. Once the ECA is
adopted by the Parties and enters into
force, U.S.- and foreign-flagged ships
will be subject to the stringent
provisions of MARPOL Annex VI within
the ECA. Since the ECA was developed
to protect air quality in port and inland
areas, these requirements will also
apply in U.S. internal waters. The U.S.
will enforce these requirements
pursuant to APPS.
More specifically, under the recentlyadopted NOX amendments to Annex VI,
in 2016, the engines on new ships
operating in ECAs must meet Tier III
NOX standards requiring advancedtechnology engines designed to cut
emissions of ozone-forming NOX by
roughly 80%. These MARPOL Annex VI
Tier III NOX standards are comparable
to the CAA Tier III NOX standards we
are proposing in this Federal Register
notice and are more fully described in
Section III. When operating outside a
designated ECA, the engines must meet
the global Tier II NOX standard, which
otherwise applies to engines on ships
beginning in 2011 and will require a
20% reduction from the current Tier I
levels. Thus, assuming the U.S. ECA is
adopted, NOX standards comparable to
those we are proposing in this NPRM
under section 213(a)(3) of the CAA will
be applicable to engines on foreignflagged vessels operating in all U.S.
waters and will be enforced under the
authority of APPS.
Because we expect the proposed
amendment to Annex VI designating a
North American ECA will be adopted in
a timely manner, the result of the
combined CAA program and the ECA
designation will be the application of
comparable NOX standards to domesticand foreign-flagged vessels which will
be enforceable under a combination of
the Act and APPS. As a result, it would
not be necessary to resolve the issue of
whether we have the authority to
impose section 213 CAA standards on
foreign-flagged vessels. For this reason,
we are not proposing to change our
current approach with regard to the
application of the Clean Air Act marine
diesel engine standards to engines on
foreign-flagged vessels. The conditions
that led us to this conclusion in 2003
are the same today, assuming approval
of the North American ECA. Because
this decision not to address our
authority to regulate foreign-flagged
vessels at this time is predicated upon
timely approval of the U.S.-Canada
proposal to amend Annex VI to
designate the North American ECA, we
will revisit this approach if the ECA is
not adopted as expected.

(3) What Comments Did EPA Receive on
This Issue?
EPA received a number of comments
in response to the ANPRM on the issue
of whether EPA should or could address
emissions from engines on foreignflagged vessels. Most commenters
express a need to include engines on
foreign-flagged vessels given the
significant contribution of such vessels’
emissions to the air pollution problem
we are addressing.107 Most of these
same commenters also express the
position that EPA has the authority to
include engines on foreign-flagged
vessels as part of its section 213
emission reduction program.108 Other
comments take the position that EPA
not only has the authority to cover such
engines and their emissions, but EPA
has an obligation to do so.109 In
contrast, EPA also received comments
opposing the view that EPA has such
authority and encouraging EPA to work
with international bodies to resolve
concerns about such emissions.110 A
brief summary of these positions
follows.
Generally, environmental nongovernmental organizations and state air
quality control authorities commenting
on the ANPRM support the view that
EPA should include engines on foreignflagged vessels in its Clean Air Act
emission reduction program. They state
that ‘‘there is no legal impediment to
regulating the emissions of foreignflagged ships operating in U.S. waters.
U.S. courts have long held that U.S.
laws apply only within the territorial
jurisdiction of the U.S., at least in the
absence of evidence of contrary
Congressional intent.’’ 111

that a U.S. statute is presumed to apply
to a foreign-flagged vessel in United
States waters unless the statute sought
to regulate ‘‘matters that involve only
the internal order and discipline of the
vessel’’ or ‘‘only the internal operations
of the ship.’’ 112 Because the United
States has a vital interest in reducing
pollutants from all visiting ships and
because ‘‘the ‘physical structure’ of a
ship is not a matter that ‘concerns only
the internal operations of the ship,’ ’’
SCAQMD believes that section 213 of
the CAA should be presumed to apply
to engines on foreign-flagged vessels.
Moreover, SCAQMD comments that,
even if a clear statement of intent to
cover engines on foreign-flagged vessels
were required, sections 213(a)(3) and (4)
unequivocally apply ‘‘to all such
nonroad engines, without
qualifications.’’ 113
Similarly, the Environmental Law &
Policy Clinic at Harvard Law School
(HLS) identifies examples of agencies
applying statutory requirements to
foreign-flagged vessels, even if
significant modifications to the vessel
may be required and ‘‘when the
governing statute does not explicitly
direct or otherwise authorize the agency
to exempt [such vessels].’’ 114
On interpretation of the term ‘‘new
nonroad engine,’’ commenters
supporting regulation of emissions from
foreign-flagged vessels believe that
section 213 provides broad authority to
regulate any emissions from new
nonroad engines and vehicles, and
although the statute does not define
what a ‘‘new nonroad engine’’ is,
neither does the statute distinguish
‘‘between U.S.-flagged and foreignflagged ships for purposes of emission
standards.’’ 115 Thus, the ambiguity, if
any, should be resolved in favor of
regulating such engines.
In that vein, SCAQMD would identify
any engine or vessel constructed after
the effective date of an EPA rule as
‘‘new’’ and subject to the applicable
standard ‘‘regardless of whether those
vessels are foreign-flagged’’ and
regardless of whether the engine or
vessel is imported. Further, SCAQMD
stated that: ‘‘While it might not be

going to travel to U.S. ports, in most
cases it is likely that this would be
known, and the shipbuilder could
always preserve the ship’s ability to do
so by meeting EPA’s standards.’’ 116
SCAQMD also addresses an EPA
position in an earlier rulemaking
regarding EPA’s interpretation of ‘‘new’’
to include ‘‘import’’ as that term is
interpreted under U.S. customs laws,
and whether engines on foreign-flagged
vessels visiting the U.S. are therefore
imported. In that context, SCAQMD
states: ‘‘the fact that a vessel is not
imported does not mean it is not ‘new’
within the ordinary meaning of the
term. * * * The inclusion of the term
‘imported’ was to cover vessels that
otherwise would not be considered
‘new,’ in order to prevent
circumvention. Thus, the definition of
‘imported’ does not limit EPA’s ability
to apply its rules to vessels that are in
fact ‘new,’ even though foreign-flagged.
We believe the ordinary meaning of
‘new’ is sufficient to cover this
concept.’’ 117 HLS similarly comments
that: ‘‘Section 213 can reasonably be
interpreted to exclude cars and trucks
that have neither been manufactured in
nor imported into the United States
because those excluded cars and trucks
do not pollute air in the U.S. Neither
Section 213 nor Section 216, however,
authorizes EPA to exclude marine
vessels that do use and pollute U.S.
ports, whether those vessels can
somehow be deemed ‘imported’ or ‘not
imported.’ ’’ 118
In contrast, Clean Air Task Force
(CATF) believes it would be ‘‘reasonable
for the Agency to continue to interpret
‘new nonroad engine’ as including
‘imported’ nonroad engines,’’ but that
EPA is not obligated to ‘‘defer to
interpretations of that term under U.S.
customs laws, in view of the
dramatically different purposes of such
laws.’’ 119 CATF explains that ‘‘[w]hile
the purpose of application of the
customs laws to ‘imports’ is to impose
a duty on merchandise that is brought
into the country on a permanent basis,
the purpose of the application of the
Clean Air Act to ‘imports’ is far
different: that is, to reduce pollution

reasonable to conclude that under the
Act, whether a vessel is operating in
U.S. waters permanently, or whether it
is flying a U.S. flag of registry, should
not be conditions for regulating its
emissions.’’ 120
Some commenters, however, take the
opposite position. API comments that
‘‘EPA’s authority to regulate non-U.S.
vessels/engines that are temporarily in
U.S waters turns on whether such
vessels/engines are ‘imported’ under the
CAA,’’ that EPA appropriately relied in
the past on the customs law’s
interpretation of ‘‘import,’’ and that
‘‘Congress did not intend to grant
authority to EPA to regulate non-U.S.
flagged vessels that are only in U.S.
waters temporarily.’’ 121
EPA appreciates all of the comments
we received on this. Although we
continue to believe it is reasonable not
to amend our current definition of new
engine, we intend to revisit that issue
without delay if the U.S. ECA is not
timely considered and adopted.
VI. Certification and Compliance
Program
This section describes the regulatory
changes proposed for the CAA Category
3 engine compliance program. In
general, these changes are being
proposed to ensure that the benefits of
the standards are realized in-use and
throughout the useful life of these
engines, and to incorporate lessons
learned over the last few years from the
existing test and compliance program.
The most obvious change is that we
are proposing to apply the plain
language regulations of 40 CFR 1042 to
Category 3 engines. These part 1042
regulations were adopted in 2008 for
Category 1 and Category 2 engines (73
FR 25098, May 6, 2008). They were
structured to contain the provisions that
are specific to marine engines and
vessels in part 1042, and apply the parts
1065 and 1068 for other provisions not
specific to marine engines. This
approach is not intended to significantly
change the compliance program from
the program currently applicable to
Category 3 engines under 40 CFR part
94, except as specifically noted in this
notice (and we are not reopening for
comment the substance of any part of
the program that remains unchanged
substantively). As proposed, these plain

language regulations would supersede
the regulations in part 94 for Category
3 engines beginning with the 2011
model year.
The changes from the existing
programs are described below along
with other notable aspects of the
compliance program. These changes are
necessary to implement the new
standards as well as to implement the
Annex VI program as required under the
amendments to the Act to Prevent
Pollution from Ships.
Finally, we are also including several
proposed changes and clarifications to
the compliance program that are not
specific to Category 3 engines. Some of
these would apply only for marine
diesel engines below 30 liters per
cylinder displacement.
A. Compliance Provisions for Category 3
Engines
In general, we are proposing to retain
the certification and compliance
provisions finalized with the Tier 1
standards for Category 3 engines. These
include testing, durability, labeling,
maintenance, prohibited acts, etc.
However, we believe additional testing
and compliance provisions will be
necessary for new standards requiring
more advanced technology and more
sophisticated emission control systems.
These changes, as well as other
modifications to our certification and
compliance provisions for Category 3
engines, are discussed below.
Our certification process is similar to
the process specified in the Annex VI
NOX Technical Code (NTC) for precertification. However, the Clean Air
Act specifies certain requirements for
our certification program that are
different from the NTC requirements.
The EPA approach differs most
significantly from the NTC in three
areas. First, the NTC allows but does not
require certification of engines before
installation (known as pre-certification
under the NTC), while EPA does require
it. Second, we include various
provisions to hold the engine
manufacturer responsible for the
durability of emission controls, while
the NTC holds the engine manufacturer
liable only before the engine is placed
into service. Finally, we specify broader
temperature ranges and allow
manufacturers less discretion in setting
engine parameters for testing, with the
goal of adopting test procedures that
represent a wide range of normal in-use
operation. We believe the regulations in
this final rule are sufficiently consistent
with NTC that manufacturers can
continue to use a single harmonized
compliance strategy to certify under
both systems.

(1) Testing
We are proposing to largely continue
the testing requirements that currently
apply for Category 3 engines with a few
exceptions.
(a) General Test Procedures
We are proposing to apply the general
engine testing procedures of 40 CFR part
1065 to Category 3 engines. This is part
of our ongoing initiative to update the
content, organization and writing style
of our regulations. For each engine
sector for which we have recently
promulgated standards (such as smaller
marine diesel engines), we refer to one
common set of test procedures in part
1065. This is because we recognized
that a single set of test procedures
would allow for improvements to occur
simultaneously across engine sectors. A
single set of test procedures is easier to
understand than trying to understand
many different sets of procedures, and
it is easier to move toward international
test procedure harmonization if we only
have one set of test procedures.
These procedures replace those
currently published in parts 92 and 94
and are fundamentally similar to those
procedures. The primary differences are
related to tighter tolerances to reduce
test-to-test variability. In most cases, a
manufacturer should be able to comply
with 1065 using its current test
equipment. Nevertheless, full
compliance with part 1065 would take
some effort on the part of
manufacturers. As such, we are
proposing some flexibility to make a
gradual transition from the part 92 and
94 procedures. For several years,
manufacturers would be able to
optionally use the part 1065 procedures.
Part 1065 procedures would generally
be required for any new testing by 2016
(except as noted below). This is very
similar to the allowance already
provided with respect to Category 1 and
Category 2 engines.
We are also proposing to allow
Category 3 manufacturers to submit data
collected using the test equipment and
procedures specified in the NOX
Technical Code, even after 2016. The
procedures in 1065 would still be the
official test procedures, however, and
manufacturers would be liable with
respect to any test results from 1065
testing. Thus, we do not believe this
allowance would have any effect on the
stringency of the standards, or how
manufacturers design and produce their
engines.
(b) Test Fuel
Appropriate test procedures need to
represent in-use operating conditions as

44478
Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
much as possible, including
specification of test fuels consistent
with the fuels that compliant engines
will use over their lifetimes. Our current
regulations allow Category 3 engine
testing using distillate fuel, even though
many vessels with these engines
currently use less expensive residual
fuel. This provision is consistent with
the specifications of the NOX Technical
Code. We are proposing to continue this
approach for Tier 2 and Tier 3. Our
primary reason for continuing this
approach is that we expect these
Category 3 engines will generally be
required to use distillate fuels in areas
that will affect U.S. air quality for most
of their operational lives. (We expect
this because we expect IMO to approve
our proposal to amend Annex VI to
designate the U.S. coastal waters as an
ECA.) However, since these engines will
not be required to use low-sulfur or
ultra low-sulfur fuel, we are also
proposing to add an explicit
requirement that a high-sulfur distillate
test fuel be used for both Tier 2 and Tier
3 testing. Our testing regulations (40
CFR 1065.703) are being revised to
specify that high-sulfur diesel test fuels
contain 800 to 2500 ppm sulfur. This
would be lower than the current
specification of 2000 to 4000 ppm. This
will allow manufacturers to test with
fuels near the ultimate in-use limit of
1000 ppm. We request comment on
applying this approach to Category 1
and/or Category 2 engines on Category
3 vessels. Commenters supporting this
approach should address how such
engines could meet the applicable PM
requirements. For example, should EPA
allow these engines to show compliance
using emission credits? Would this
require us to set a higher Family
Emission Limit cap for engines using
this allowance? See also Section VI.C.1
for further discussion of these engines.
(c) Testing Catalyst-Equipped Engines
In our existing programs that require
compliance with catalyst-based engines
(such as the Category 1 & 2 engine
program), we require manufacturers to
test prototype engines equipped with
prototype catalyst systems. However, it
is not clear that this approach would be
practical for Category 3 engines. These
are problematic because of their size
and because they tend to be a least
partially custom built. Requiring a
manufacturer to construct a full-scale
catalyst system for each certification test
would be extremely expensive.
We are proposing an optional special
certification procedure to address this
concern. The provisions are in
§ 1042.655 of the proposed regulations.
The emission-data engine must be tested
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
in the specified manner to verify that
the engine-out emissions comply with
the Tier 2 standards. The catalyst
material must be tested under
conditions that accurately represent
actual engine conditions for the test
points. This catalyst testing may be
performed on a benchscale.
Manufacturers must include a detailed
engineering analysis describing how the
test data collected for the engine and
catalyst material demonstrate that all
engines in the family will meet all
applicable emission standards.
Manufacturers must verify their design
by testing a complete production engine
and catalysts in its final assembled
configuration.
(d) Testing Production Engines
Under the current regulations,
manufacturers must test a sample of
their Category 1 and Category 2 engines
during production. We are now
proposing similar provisions for
Category 3 engines. While in the past we
did not believe that such testing was
necessary, circumstances have changed
in two important ways. First, relatively
inexpensive portable test systems have
recently become available. This greatly
reduces the cost of testing an engine in
a ship. Second, the need to verify that
production engines actually comply
with the emission standards increases as
standards become more stringent and
emission control technologies become
more complicated.
Specifically, we are proposing that
every new Tier 2 or later Category 3
engine be tested during the vessel’s sea
trial to show compliance with the
applicable NOX standard. Any engine
that fails to comply with the standard
would need to be repaired and retested.
Since we are not proposing PM
standards for Category 3 engines, and
because PM measurement is more
difficult than measuring only gaseous
emission, we would not require PM
measurement during testing after
installation, provided PM emissions
were measured during certification.
One concern that manufacturers have
raised in the past is that it can be
difficult to achieve the exact test points
in use. Therefore, we are proposing to
allow manufacturers flexibility with
respect to test points when testing
production engines, consistent with the
equivalent allowance under the NOX
Technical Code. Where manufacturers
are unable to duplicate the certification
test points during production testing,
we are proposing to allow them to
comply with an alternate ‘‘at-sea
standard’’ that is 10 percent higher than
the otherwise applicable standard. This
is specified in § 1042.104(g).
PO 00000
Frm 00038
Fmt 4701
Sfmt 4702
Since we are proposing to require
testing of every production engine, we
are also proposing to exclude Category
3 engines from selective enforcement
audits under 40 CFR part 1068.
(e) PM Measurement
We are proposing to require
manufacturers to measure PM emissions
along with NOX, HC, and CO during
certification testing to report these
results along with the other test data.
This is similar to our recently proposed
requirement for manufacturers to
measure and report certain greenhouse
gas emissions for a variety of nonroad
engine sectors.122 Manufacturers should
be able to collect these data using standalone partial flow PM measurement
systems. In recent years, several vendors
have developed such systems to be
compliant with the requirements of
1065.
It is worth noting that in the past,
there has been some concern regarding
the use of older PM measurement
procedures with high sulfur fuels. The
primary issue of concern was variability
of the PM measurement, which was
strongly influenced by the amount of
water bound to sulfur. However, we
believe improvements in PM
measurement procedures, such as those
specified in 40 CFR 1065, have
addressed these issues of measurement
variability. The U.S. Government
recently submitted proposed procedures
for PM measurement to IMO.123
(2) Low Power Operation and Mode
Caps
Emission control performance can
vary with the power at which the engine
operates. This is potentially important
because Category 3 engines can operate
at relatively low power levels when they
are operating in port areas. Ship pilots
generally operate engines at reduced
power for several miles to approach a
port, with even lower power levels very
close to shore. The International
Organization for Standardization (ISO)
E3 and E2 test cycles, which are used
for emission testing of propulsion
marine engines, are heavily weighted
towards high power. In the absence of
other requirements, it would be possible
for manufacturers to meet the cycleweighted average emission standards
without significantly reducing
emissions at low-power modes. This
could be especially problematic for Tier

3 engines relying on urea-SCR for NOX
control, since the effectiveness of the
control is directly affected by the
amount of urea that is injected and there
would be an obvious economic
incentive for manufacturers and
operators to minimize the amount of
urea injected.
We are addressing these concerns in
two ways. First, we are applying mode
caps for NOX emissions that will ensure
that manufacturers design their
emission controls to be fully effective at
25 percent power. This would require
that manufacturers meet the applicable
NOX standard at each individual test
point, and not merely as a weighted
average of the test points. The caps
would only apply for NOX emissions,
and manufacturers would not be
required to meet the HC and CO
standards at each test point. For HC and
CO, manufacturers would only be
required to meet the applicable
standards as a weighted average of the
test points
The other concern is related to power
levels other than the test points. To
address this, we will continue to rely on
our prohibition of defeat devices to
ensure effective control for lower
powers. Most significantly, this would
prohibit manufacturers from turning off
the urea supply to SCR systems at these
points, unless the exhaust gas
temperature was too cool for the SCR
catalyst to function properly. (Urea at
these low temperatures does not react
with NOX molecules and can lead to
high emissions of ammonia.)
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
(3) On-Off Technologies
One of the features of the SCR
technologies that are projected to be
used to meet the Tier 3 NOX standards
is that they are not integral to the engine
and the engine can be operated without
them. They will also require the
operator to supply the proper reductant.
Thus, these technologies are potentially
‘‘on-off’’ technologies. Switching to
distillate fuel instead of residual fuel to
reduce SOX and PM emissions can be
thought of in the same way.
The increased operating costs of such
controls associated with urea (or other
reductants) or with distillate usage
suggest that it may be reasonable to
allow these systems to be turned off
while a ship is operated on the open
ocean, far away from sensitive areas that
are affected by ship emissions. This is
the basis of the MARPOL Annex VI ECA
approach, with one set of limits that
would apply when ships are operated in
sensitive areas and another that would
apply when ships are operated outside
those limits.
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
We are proposing a new regulatory
provision in § 1042.115(g) to address the
use of on-off technologies on Category 3
engines subject to the Tier 3 standards.
This provision would require the
manufacturer to obtain EPA approval to
design the engines to have on-off
features. It would also require the
engine’s onboard computer to record the
on-off operation (including geographic
position and time) and require that the
engine comply fully with the Tier 2
standards when the Tier 3 controls are
turned off. We request comment on
applying this approach to Category 1
and/or Category 2 engines on Category
3 vessels.
At this time, our goal is to require
manufacturers to comply with the Tier
3 standards in all areas that will
ultimately be included in any Emission
Control Area, which should include all
areas for which EPA has determined
that Category 3 engines significantly
affect U.S. air quality. As discussed in
Section V.A, we have not yet
determined the extent to which
Category 3 engines affect air quality in
the U.S. territories, areas of Alaska west
of Kodiak, or the smallest Hawaiian
islands. Therefore, we are proposing to
include an interim provision to exclude
those areas with respect to the Tier 3
standards at this time. We will revisit
this should our review of available
modeling results or other information
indicate that compliance with the Tier
3 standards should be required for some
or all of these areas.
(4) NOX Monitoring
We are proposing that Category 3
engines equipped with on-off controls
must be equipped to continuously
monitor NOX concentrations in the
exhaust. Engine manufacturers would
be required to include systems to
automatically alert operators of any
operation with the emission controls on
where NOX concentrations indicate
malfunctioning emission controls. We
would also require the engine to record
in nonvolatile computer memory any
such operation. However, we would not
require monitoring NOX concentrations
during operation for which the emission
controls are allowed to be turned off,
provided the record indicated that the
controls were turned off. Where the
NOX monitor system indicates a
malfunction, operators would be
required to investigate the cause and
make any necessary adjustments or
repairs.
We are proposing to define as a
malfunction of the emission controls
any condition that would cause an
engine to fail to comply with the
applicable NOX standard (See Section
PO 00000
Frm 00039
Fmt 4701
Sfmt 4702
44479
VI.A.1.d for a discussion of standards
that would apply for installed engines at
sea). Such malfunctions could include
maladjustment of the engine or controls,
inadequate reductant, or emission
controls turned off completely. We
recognize that it is not possible to
perfectly correlate a measured NOX
concentration with an equivalent cycleweighted emission result. Therefore, the
proposed requirement would allow
engine manufacturers to exercise good
engineering judgment in using
measured NOX concentrations to
monitor the emission performance of
the engine. We request comment on the
need for less subjective approaches. For
example, should we establish caps for
concentrations based on the
concentrations measured during
certification?
(5) Parameter Adjustment
Given the broad range of ignition
properties for in-use residual fuels, we
expect that our current in-use
adjustment allowance for Category 3
engines would result in a broad range of
adjustment. We are therefore
considering a requirement for operators
to perform a simple field measurement
test to confirm emissions after
parameter adjustments or maintenance
operations, using onboard emission
measurement systems with electroniclogging equipment. We expect this issue
will be equally important for more
advanced engines that rely on water
injection or aftertreatment for emission
reductions. Onboard verification
systems could add significant assurance
that engines have properly operating
emission controls.
We envision a simpler measurement
system than the type specified in
Chapter 6 of the NOX Technical Code.
As we described in the 2003 final rule,
we believe that onboard emission
equipment that is relatively inexpensive
and easy-to-use could verify that an
engine is properly adjusted and is
operating within the engine
manufacturer’s specifications. Note that
Annex VI includes specifications
allowing operators to choose to verify
emissions through onboard testing,
which suggests that Annex VI also
envisioned that onboard measurement
systems could be of value to operators.
We request comment on requiring
onboard verification systems on ships
with Category 3 marine engines and on
a description of such a system. In
particular, we request comment on
whether the continuous NOX
monitoring system described in the
previous subsection would be sufficient
to address these concerns.

(6) In-Use Liability
Under the existing Tier 1 program for
Category 3 engines, owners and
operators are required to maintain,
adjust, and operate the engines in such
a way as to ensure proper function of
the emission controls. These
requirements, which are described in 40
CFR 94.1004, are being continued in the
regulations in part 1042 (See § 1042.660
of the proposed regulations for these
requirements). Specifically, these
provisions require that all maintenance,
repair, adjustment, and alteration of the
engine be performed using good
engineering judgment so that the engine
continues to meet the emission
standards. Each two-hour period of
operation of an engine in a condition
not complying with this requirement
would be considered a separate
violation. Owners will also continue to
be required to keep certain records
onboard the vessel and report annually
to EPA whether or not the vessel has
complied with these and other
requirements.
(7) Replacement Engines
The existing provisions of § 1042.615
provide an exemption that allows
manufacturers to produce new
uncertified engines when they are
needed to replace equivalent existing
engines that fail prematurely. For many
engine sectors, this practice is common,
but represents a very small faction of a
manufacturer’s total engine production.
However, since we do not believe this
practice is either common or necessary
for Category 3 engines, we are proposing
to not allow this exemption for Category
3 engines.

B. Compliance Provisions To Implement
Annex VI NOX Regulation and the NOX
Technical Code
In addition to the Clean Air Act
provisions being proposed in this
action, we are also proposing new
regulations to implement certain
provisions of the Act to Prevent
Pollution from Ships. These regulations
are proposed as a new part 1043 of title
40.
The Act to Prevent Pollution from
Ships establishes a general requirement
for vessels operating in the exclusive
economic zone and navigable waters of
the United States to comply with
MARPOL Annex VI. It also gives EPA
and the Administrator the authority to
further implement MARPOL Annex VI.
Many of the requirements relating to
NOX emissions and fuel sulfur limits
can be implemented without the need
for further elaboration in that the
Annex, along with the NOX Technical
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
Code, provides instructions on how to
demonstrate compliance with those
requirements. However, APPS
authorizes the Administrator to
prescribe any necessary or desired
additional regulations to assist in
carrying out the provisions of
Regulations 12 through 19 of Annex VI
(see 33 USC 1903(c)(2)). Specifically,
the regulations being proposed in this
NPRM in part 1043 of title 40 are
intended to assist in the implementation
of the engine and fuel requirements
contained in Regulation 13, 14, and 18
of MARPOL Annex VI.. They address
such issues as how to obtain an Engine
International Air Pollution Prevention
(EIAPP) certificate (which is equivalent
in many ways to a Clean Air Act
certificate of conformity), exemptions
for vessels used exclusively in domestic
service, and requirements for vessels not
registered by a country that is a Party to
Annex VI.
In contrast to the compliance program
for Category 3 engines described in
Section VI.A, the 1043 regulations
described in this section would apply to
all marine diesel engines above 130 kW.
Similarly, the MARPOL Annex VI fuel
requirements apply to all fuel oil used
onboard a vessel, defined as any fuel
delivered to and intended for
combustion purpose for propulsion or
operation on board a ship, including
distillate and residual fuels.
(1) EIAPP Certificates
In general, an engine can be dualcertified under EPA’s Clean Air Act
marine diesel engine program and the
MARPOL Annex VI/APPS program.
However, we propose to require that
engine manufacturers submit separate
applications for the 1042 and EIAPP
certificates. The proposed regulations in
part 1043 specify the process that would
apply. The process for obtaining the
EIAPP is very similar to the process for
obtaining a certificate of conformity
under part 1042, and although there are
differences between the programs,
manufacturers should be able to comply
with both programs with very little
additional work. The primary
differences are that, to certify to the
MARPOL Annex VI standards, the
manufacturer must include a copy of the
Technical File and onboard NOX
verification procedures (as specified in
Section 2.4 of the NOX Technical Code)
and is not required to provide
information about useful life, emission
labels, deterioration factors, or PM
emissions.124 Currently engine
124 See 68 FR 9746, February 28, 2003, at 9774–
5 for a discussion of these differences as they relate
to Category 3 marine diesel engines.
PO 00000
Frm 00040
Fmt 4701
Sfmt 4702
manufacturers will be able to apply for
both certifications using the certification
templates and test data.
Consistent with our 1042 program,
our proposed 1043 program would
require that each engine installed or
intended to be installed on a U.S.flagged vessel have an EIAPP before it
is introduced into U.S. commerce. The
proposed regulations would create a
presumption that all marine engines
manufactured, sold, or distributed in
U.S. commerce would be considered to
be intended to be installed on a U.S.flagged vessel, although this
presumption could be rebutted by clear
and convincing evidence to the contrary
(evidence that the engine is intended for
export, for example).
(2) Approved Methods
The 2008 amendments to MARPOL
Annex VI added a new provision to the
engine standards in Regulation 13 that
extends the Tier I NOX limits to certain
engines installed on ships constructed
on or after January 1, 1990 through
December 31, 1999. Specifically,
engines with power output greater than
5,000 kW and with per cylinder
displacement at or above 90 liters
installed on such ships would be
required to meet the Tier I NOX limits
if a certified Approved Method is
available. An Approved Method may be
certified by the Administration of any
flag state, but once one is registered
with the IMO the owner of such an
engine must either install the Approved
Method or demonstrate compliance
with the Annex VI Tier I limits through
some other method. We are proposing to
include a regulatory section codifying
this requirement. These regulations are
contained in § 1043.50.
(3) Other Annex VI Compliance
Requirements
Engine manufacturers, vessel
manufacturers, vessel owners, and fuel
providers, fuel distributors, and other
directly regulated stakeholders are
required to comply with all aspects of
Regulations 13, 14, and 18 of Annex VI
as well as the NOX Technical Code.
These include requirements for engine
operation, fuel use, fuel oil quality, and
various recordkeeping requirements
(e.g., record book of engine parameters,
engine technical file, fuel switching
procedures, bunker delivery notes and
associated fuel samples, and fuel
sampling procedures). While
certification, compliance, and
verification procedures are set out in the
Annex and related documents, we
nonetheless seek comment on whether
additional regulatory provision under
APPS would be necessary or helpful.
E:\FR\FM\28AUP2.SGM
28AUP2
Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
For example, the contents of a bunker
delivery note are set out in Appendix V
to MARPOL Annex VI and § 1043.80.
Are there aspects of these criteria that
should be further clarified, or are there
parameters required in Regulation 18
that should also be included on the
bunker delivery note? Similarly, the
process for verifying the sulfur content
of fuel oil samples is set out in
Appendix VI to the amended Annex VI.
Is there any aspect of this procedure that
requires further clarification?
Commenters supporting the inclusion of
additional language related to these or
other requirements are encouraged to
include specific recommendations.
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
(4) Non-Party Vessels
The proposed regulations specify that
vessels flagged by a country that is not
a party to MARPOL (known as nonParty vessels) must comply with
Regulations 13, 14, and 18 of Annex VI
when operating in U.S. waters. This
requirement would fulfill the
requirement of 33 U.S.C. 1902(e), which
requires the adoption of regulations for
non-Party vessels such that they are not
treated more favorably than vessels of
countries that are party to the MARPOL
Protocol. However, since such vessels
cannot get EIAPP certificates, this
proposed provision requires non-party
vessels to obtain equivalent
documentation of compliance with the
NOX standards of Annex VI. We request
comment on this provision.
(5) Internal Waters
APPS applies Annex VI requirements,
including amendments to Annex VI
(such as ECA designations) that are
binding on the United States, to all
persons in navigable waters of the U.S.,
including internal waters. However, our
recent proposal for ECA designation that
was submitted to IMO, although
intended to protect air quality in U.S.
ports and internal areas, does not
explicitly state that it applies to internal
waters. Therefore, we are proposing
regulatory text under the authority of
APPS, in order to avoid confusion on
whether vessels must meet ECA
requirements in internal waters. The
text clarifies that the ECA requirements
generally apply to internal waters, such
as the Mississippi River and the Great
Lakes, that can be accessed by oceangoing vessels. Vessel emissions in these
waters affect U.S. air quality to an equal,
if not greater extent that emissions
taking place in coastal waters.
Specifically, the proposed rule would
require compliance with the fuel sulfur
requirements and the NOX emission
standards of Regulations 13, 14, and 18
in internal waters. However, the ECA
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
requirements do not apply in internal
waters, such as those in northwestern
Alaska, that are not shoreward of an
ECA designated under Annex VI; rather
the non-ECA requirements of Annex VI
apply for these waters.
(6) Exemptions and Exclusions
Under MARPOL Annex VI and APPS,
certain vessels are excluded from some
or all of the requirements. Consistent
with Annex VI and APPS, the
regulations in 1043 would exclude
public vessels and engines intended to
be used solely for emergencies. For the
purpose of this provision, the term
‘‘public vessels’’ includes all warships
and naval auxiliary vessels, as well as
any other vessels owned or operated by
a sovereign country engaged in
noncommercial service. Consistent with
the provisions in APPS, we are not
proposing to apply the Annex VI
requirements to U.S.-flagged public
vessels. It should be noted, however,
that not all public vessels are exempt
from our Clean Air Act engine and fuel
requirements. Only public vessels
covered by a national security
exemption under § 94.908 or § 1042.635
are exempt from the Clean Air Act
program.
The category of emergency engines
includes engines that power equipment
such as pumps that are intended to be
used solely for emergencies and engines
installed in lifeboats intended to be
used solely in emergencies. It should be
noted that the emergency engine
provisions in the Annex and part 1043
are similar but not identical to the
emergency engine provisions in our
Clean Air Act program or the process of
obtaining our CAA exemptions. In
particular, the emergency engine
exemption from the CAA requirements
applies only with respect to the catalystbased Tier 4 standards.
We are exempting from the MARPOL
Annex VI NOX standards engines
installed on vessels registered or flagged
in the United States provided the vessel
remains within the EEZ of the United
States. These engines would still be
required to meet stringent emission
standards since they are covered by our
Clean Air Act program. In addition, the
fuels used by these vessels are also
covered by our Clean Air Act program,
which has more stringent fuel
requirements than Annex VI. Therefore,
we are also proposing that as long as the
operators of these domestic vessels
comply with these more stringent Clean
Air Act fuel requirements, they will be
deemed to be in compliance with the
Annex VI requirements. The
combination of these proposed
provisions would mean that a fishing
PO 00000
Frm 00041
Fmt 4701
Sfmt 4702
44481
vessel that operates out of a U.S. port
and that never leaves U.S. waters would
not be required to have an EIAPP for all
engines above 130 kW, a record book of
engine parameters and a technical file
for each engines, and vessels over 400
gross tons would not be required to
maintain bunker delivery notes (vessels
under 400 gross tons are not required by
Regulation 18 of MARPOL Annex VI to
have bunker delivery notes). Instead, the
engines on that vessel would be
required to be in compliance with our
marine diesel engine standards and be
required to comply with manufacture
requirements with regard to the fueling
of those engines. We are also proposing
to explicitly preclude these engines
from being certified to use residual fuel
if they are exempt from the part 1043
requirements. Thus, these engines
would be required to always use cleaner
fuels than are required by Annex VI.
U.S. vessels that operate or may operate
in waters that are under the jurisdiction
of another country are not exempt from
these provisions, and the owner of any
such vessel may be required by that
country to show compliance with
Annex VI. Therefore, the owner should
be sure to maintain the appropriate
paperwork for that engine and have the
appropriate engine certification. It
should be noted that engines that must
show compliance with the Annex VI
standards are not exempt from EPA’s
standards for Category 1 or Category 2
engines. We are requesting comment on
this overall approach for domestic
vessels. In particular, we are requesting
comment on whether we should extend
this exemption to U.S. vessels that
sometimes leave the EEZ of the United
States, but that never enter waters under
the jurisdiction of another country.
Finally, spark-ignition, nonreciprocating engines, and engines that
do not use liquid fuel are not included
in Regulation 13 of the Annex VI
program and therefore we are not
proposing that they be covered by the
proposed APPS regulations with respect
to NOX emissions. However, the
MARPOL Annex VI fuel requirements
do apply for these vessels. These
engines are generally subject to separate
Clean Air Act requirements and
therefore will generally be in
compliance with the fuel sulfur limits.
C. Changes to the Requirements Specific
to Engines Below 30 Liters per Cylinder
The amendments to MARPOL Annex
VI were adopted in October of 2008,
after we finalized our Clean Air Act Tier
3 and Tier 4 standards for Category 1
and Category 2 engines (May 6, 2008, 73
FR 25097). While these two programs
are very similar, there are a few
E:\FR\FM\28AUP2.SGM
28AUP2
44482
Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
differences between them with regard to
their engine requirements. We continue
to believe that our Tier 3 and Tier 4
standards will yield the greatest degree
of emission reduction that is
technologically feasible, taking into
account costs, safety, and other factors
for those engines. However, we are
considering changes to our CAA
program to facilitate compliance with
both programs. We seek comment on
these potential changes, described
below.
In addition, some of the provisions
described in Section VI.D may also
apply to Category 1 and Category 2
marine diesel engines, regarding nondiesel engines and technical
amendments to our current program.
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
(1) MARPOL Annex VI and EPA’s
Standards for Category 1 and Category 2
Engines
As discussed throughout this notice,
we are proposing to adopt the new
Annex VI NOX limits under our CAA
program for Category 3 engines.
Specifically, we are proposing to adopt
the Tier II and Tier III standards as our
Tier 2 and Tier 3 standards for engines
above 30 liters per cylinder. The new
Annex VI NOX limits are shown in
Table III–1 in Section III.B.1 above.
With regard to Category 1 and
Category 2 marine diesel engines, the
Annex VI standards are different from
our Clean Air Act program in several
ways. First, with regard to the NOX
limits, EPA’s Tier 2 NOX limits, which
are similar in stringency to the Annex
VI Tier II limits, have been in effect
since 2004–2007, depending on engine
size. EPA has intermediary Tier 3 NOX
limits, which begin in 2012–2014,
depending on engine size, and are more
stringent than the Annex VI Tier II
standards that apply beginning in 2011.
Also, while EPA’s Tier 4 NOX limits for
Category 1 and Category 2 engines are
similar in stringency to the Annex VI
Tier III NOX limit, they apply only to
engines above 600 kW.125
Second, in addition to NOX, EPA’s
marine diesel engine program includes
limits for PM, HC, and CO emissions.
Annex VI, in contrast, addresses marine
diesel PM emissions through fuel
standards (see Section III.B.2 above for
an explanation for why this is
appropriate for Category 3 engines).
125 We continue to believe it is not appropriate to
adopt SCR-forcing Tier 4 standards for engines
below 600 kW in our national program, for the
reasons described in our 2008 Final Rule (May 6,
2008, 73 FR 25097) . Specifically, there are
significant challenges regarding the ability of
manufacturers of the small vessels that use these
engines for propulsion to incorporate SCR systems
into their vessel designs. These concerns are not as
significant for auxiliary engines used on OGV.
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
EPA’s Tier 4 PM standards for Category
1 and Category 2 engines are expected
to be met through PM aftertreatment
technology, which will require the use
of ultra-low sulfur diesel fuel. Owners
of vessels that operate internationally,
including ocean-going vessels, were
concerned with the availability of this
ultra-low sulfur fuel, i.e., 15 ppm sulfur
fuel, outside of the United States. In
response to concerns with fuel
availability, we created a provision that
would exempt Category 1 and Category
2 engines installed on certain OGV from
the Tier 4 standards. This permanent
exemption from the Tier 4 standards is
available to owners that can
demonstrate their vessel will operate
primarily outside the United States, as
evidenced by obtaining and maintaining
certification for the International
Convention for the Safety of Life at Sea
(SOLAS) for the vessel. The exempted
engines are required to meet EPA’s Tier
3 standards, which consist of interim
NOX and PM standards. Note that we
indicated we do not expect to issue any
permanent exemptions until 2021; prior
to that time, it is our expectation that
fleets would use their existing pre-Tier
4 vessels for operations where ULSD
may not be available.
Third, and finally, EPA’s marine
diesel engine compliance requirements
are slightly different from the MARPOL
Annex VI program, regarding engine
durability, test fuels (in EPA’s program,
an engine must be certified on the fuel
type it will use in operation; see 40 CFR
1042.104 and 501), and some testing
parameters. However, the programs are
sufficiently consistent that engine
manufacturers can use a single
harmonized compliance strategy to
certify under both systems.
(2) Tier 4 Compliance Option for
Category 1 and 2 Engines on U.S.
Vessels That Operate Internationally
Engines on U.S. vessels that comply
with EPA’s Tier 2 or Tier 3 standards
will be in compliance with the Annex
VI Tier I and Tier II NOX limits, since
EPA’s limits are similar in stringency or
are slightly more stringent.
Beginning in 2016, however, some
engines in U.S. vessels that operate
internationally could be out of
compliance with the MARPOL NOX
limits, even though they comply with
EPA’s CAA program. This would occur
in two situations. If an owner obtained
a permanent exemption from the EPA’s
Tier 4 standards for engines above 600
kW, as described above, those engines
would not meet the Annex VI Tier III
NOX limits. If the vessel has engines
below 600 kW, which are only subject
to EPA’s Tier 3 standards for NOX and
PO 00000
Frm 00042
Fmt 4701
Sfmt 4702
PM, then those engines would also not
meet the Annex VI Tier III NOX limits.
If a vessel is found to be in noncompliance with Annex VI, it can be
detained in a foreign port until the
deficiency is corrected.
Therefore, as a result of the new
situation brought about by the Annex VI
amendments, we are considering
revising our program for Category 1 and
2 engines. To avoid U.S. vessels being
found in non-compliance with the
Annex VI NOX limits in foreign ports,
we are considering rescinding the
permanent exemption for EPA’s Tier 4
standards for Category 1 and 2 engines
and, instead, adopting a compliance
flexibility that would give owners the
choice between complying with EPA’s
Tier 4 NOX and PM standards or the
MARPOL Annex VI Tier III NOX
standards for all engines installed on a
vessel. This flexibility would ensure
that owners of OGV that will operate in
any ECA are in compliance with
MARPOL Annex VI, while allowing
owners of vessels that never operate in
waters under the jurisdiction of another
country to comply with the U.S.
program instead.
This compliance option would be
available beginning in 2016. The
flexibility would be limited to vessels
that are operated primarily outside of
the United States, as evidenced by the
vessel obtaining and maintaining
SOLAS certification and appropriate
EIAPP certification demonstrating
compliance with Annex VI. U.S. vessels
that are Jones Act vessels and/or that are
used primarily between U.S. ports
would not be eligible for this
compliance flexibility given they do not
have the concerns causing the need for
an exemption from our CAA Tier 4
standards (i.e., availability of 15 ppm
sulfur fuel). The exercise of the
compliance flexibility would take the
form of a formal election to comply with
the Annex VI Tier III NOX limits in lieu
of EPA’s Tier 4 marine diesel engine
emission limits. This formal election
would be deposited with EPA and
would be necessary so the engine
manufacturer can provide an Annex VIcompliant engine to the vessel builder
in lieu of a CAA Tier 4 engine.
This compliance option could yield
additional NOX emission benefits to
U.S. air quality over the current
permanent exemption approach. Under
the current program, exempted engines
would meet only the Tier 3 standards.
For engines up to 3,300 kW, this is
about a 20 percent reduction from Tier
1 (for larger engines, the Tier 3 NOX
limit is the same as the Tier 2 limit
because the Tier 4 standards begin
earlier, in 2014). Under the revised
E:\FR\FM\28AUP2.SGM
28AUP2
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
approach, all vessels would need to
meet aftertreatment-forcing NOX limits
when operating in ECAs. The choice of
either the EPA Tier 4 limits or the
Annex VI Tier III limits is expected to
yield similar NOX benefits. While the
Annex VI Tier III NOX limits are slightly
less stringent (an 80 percent reduction
from Tier 1 compared to an 85 percent
reduction from EPA’s Tier 4 standard),
the Annex VI program covers more
engines (those 130–600 kW). Applying
either of these programs could represent
a significant NOX reduction over the
Tier 3 limits that would otherwise
apply.
The main difference between the two
programs is that the Annex VI program
does not include PM standards. This
means that instead of meeting EPA’s
Tier 3 PM standards (which are about a
45 percent reduction from the Tier 2 PM
limit), the engines that exercise the
Annex VI Tier III option would be
unconstrained for PM. However, this
will be offset by the greater reductions
in NOX (and associated indirect PM)
emissions that would be achieved
through the application of SCR-forcing
standards to all engines above 130 kW
installed on the vessel.
Owners of qualified vessels that
operate in ECAs would be expected to
choose the Annex VI Tier III option to
ensure that their engines below 600 kW
are in compliance in those areas.
Owners of vessels that never operate in
any ECA, including the North American
ECA, may also choose that option if they
are concerned with availability of ultralow sulfur diesel fuel that would be
required for EPA’s Tier 4 PM controls.
Annex VI Tier III engines that are
used in this program would be required
to be certified by EPA, although we
would accept test data obtained for
compliance with the IMO program for
this program.
We are also seeking comment on
whether we should consider such a
compliance option to replace our
temporary exemption program for
Category 1 and 2 engines. The
temporary exemption was designed to
address the case in which a U.S. vessel
is contracted to operate overseas for an
extended period of time in an area in
which 15 ppm fuel is not available.
Owners of vessels that obtain this
exemption can disable the Tier 4
controls on Category 1 and Category 2
engines. The exemption is temporary in
that the controls must be re-enabled
before the vessel is returned to service
in the United States. It should be noted
that while the compliance flexibility
described above would ensure that the
vessel achieves the Annex VI Tier III
standards while operating in another
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
country, it also means that the vessel
would not achieve EPA’s Tier 4 PM
requirements when it is returned to
service in the United States.
(3) On/Off Technology for Category 1
and 2 Engines
As described in Section VI.A.3 above,
we are proposing to allow the use of
auxiliary emission control devices
(AECDs) that would allow modulation
of emission control equipment on
Category 3 engines outside of specific
geographic areas. These AECDs would
be subject to certain restrictions: (1) The
AECD would be available for the Tier 3
standards only; (2) the AECD would
modulate emission controls only while
operating in areas where emissions
could reasonably be expected to not
adversely affect U.S. air quality; and (3)
and an engine equipped with an AECD
must also be equipped with a NOX
emission monitoring device.
Ocean-going vessels with Category 3
propulsion engines have several smaller
Category 1 and Category 2 engines to
provide auxiliary power. In addition,
while most U.S. vessels with Category 1
or Category 2 propulsion engines
operate primarily or exclusively on our
inland waterways, in our commercial
ports, or in areas close to our coastlines,
there are Category 1 and 2 vessels that
operate more like ocean-going vessels.
Our current program for Category 1
and Category 2 engines does not allow
the use of AECDs on these engines.
Instead, it requires the NOX and PM
aftertreatment devices on these engines
to be functional at all times unless the
owner of the vessel has obtained from
EPA either a temporary or permanent
exemption from the Tier 4 standards.
Most U.S. vessels with Category 1 or
Category 2 propulsion engines do not
operate outside of our inland and
coastal water systems, and therefore
would not benefit from a provision that
would allow AECDs. Additionally, we
are concerned that use of this
technology/strategy could have
detrimental air quality impacts if
operated inappropriately in or around
U.S. waters. However, we are seeking
comment as to whether we should
consider allowing such an AECD
provision to apply to other categories of
marine diesel engines.
First, we seek comment on whether
the application of this provision should
be limited to Category 1 and Category 2
engines used as auxiliary engines on
ocean-going vessels with Category 3
propulsion engines, to Category 1 and
Category 2 engines installed on vessels
that operate primarily outside the
United States, or to some other group of
vessels.
PO 00000
Frm 00043
Fmt 4701
Sfmt 4702
44483
Second, if we allowed AECDs on
engine categories with a PM emission
standard, we seek comment on whether
they should be limited to NOX
emissions only.
Third, we request comment on the
NOX (and potentially PM) levels that
would need to be achieved while then
AECD is in operation: the Annex VI Tier
II NOX limits or EPA’s Tier 3 NOX and
PM limits.
Finally, we seek comment on whether
an AECD provision should be used
instead of the temporary exemption
program for Category 1 and 2 engines.
In this case, instead of extending the
compliance flexibility to these vessels as
described in Section VI.C.1, owners of a
vessel that is contracted to operate
outside the United States for an
extended period of time could purchase
and use engines equipped with on/off
features, provided the emission control
devices were operational when the
vessel is operating in areas that affect
U.S. air quality. We seek comment on
whether the AECD approach is more
useful for these vessels or the
compliance flexibility described above.
D. Other Proposed Regulatory Issues
In addition to the changes described
in Sections VI.A and VI.C, we are also
proposing changes that would apply to
Category 1 marine engines in general,
and/or to other types of engines.
(1) Non-Diesel Engines
Most of the preceding discussions
have focused on conventional diesel
engines using either diesel fuel or
residual fuels. It is important to
highlight two other types of engines
being affected by this proposal: engines
using other fuels and gas turbine
engines.
(a) Engines Not Using Diesel Fuel
For all categories of marine engines,
our existing standards apply to all
engines meeting the definition of
compression-ignition, regardless of the
fuel type. For example, compressionignition Category 3 engines that burn
natural gas are currently subject to our
Tier 1 standards and would be subject
to our proposed Tier 2 and Tier 3
standards. We are proposing to continue
to apply this approach for all marine
engines subject to our standards.
The testing regulations in part 1065
include test fuel specifications for diesel
fuel, residual fuel, and natural gas (as
well as for gasoline and liquefied
petroleum gas, which would not
typically be used in a compressionignition engine). To certify an engine for
a different fuel type, a manufacturer
would need to obtain EPA approval to
E:\FR\FM\28AUP2.SGM

44484
Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
use an alternate fuel which it
recommends for testing. All other
aspects of certification would be the
same.
(b) Gas Turbine Engines
Gas turbine engines are internal
combustion engines that can operate
using a variety of fuels (such as diesel
fuel or natural gas) but do not operate
on a compression-ignition or other
reciprocating engine cycle. Power is
extracted from the combustion gas using
a rotating turbine rather than
reciprocating pistons. The primary type
of U.S.-flagged vessels that use gas
turbine engines are naval combat ships.
While a small number have been used
in commercial ships, we are not aware
of any current sales for commercial
applications. They can range in size
from those equivalent in power to midsize Category 1 engines to those that
produce the same power as Category 3
engines. None of these engines are
currently subject to our standards
because they do not meet the definition
of compression-ignition engines in our
existing regulations.
To date, this omission has not been a
concern because only a small number of
turbine-powered vessels have been
produced and nearly all of them would
have been eligible for a national security
exemption. However, we are concerned
that this exclusion may become a
loophole in the future for operators
hoping to avoid using engines with
advanced catalytic emission controls.
To a lesser degree, we also have
concerns about the possibility of other
non-reciprocating engines being
excluded. We are proposing to close this
potential loophole by revising the
regulations to treat new gas turbine
engines (as well as other nonreciprocating engines) as compressionignition engines and applying our
standards for new Category 1 and
Category 2 engines (including NOX, HC,
CO, and PM standards) to gas turbine
engines.
To incorporate this approach in our
marine emission control program, we
are proposing a change to our
definitions of Category 1 and Category 2
to include gas turbine engines. Since
turbine engines have no cylinders, we
need to address how to apply any
regulatory provisions that depend on a
specified value for per-cylinder
displacement. A reasonable approach
would be to apply the standards based
on equivalent power ratings, to the
extent possible. Specifically, we are
proposing to redefine ‘‘Category 1’’ to
include gas turbines with rated power
up to 2250 kW and to redefine
‘‘Category 2’’ to include all gas turbines
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
with higher power ratings. This would
mean we would not consider any gas
turbines as ‘‘Category 3’’ engines. The
largest gas turbine engines would be
considered to be Category 2 engines,
even those that had rated power more
typical of Category 3 diesel engines.
We are aware that some companies
are manufacturing new highperformance recreational vessels using
gas turbine engines. In at least some
cases, the engines are modified from
surplus military aircraft engines. We
have not yet determined whether such
recreational engines should be held to
the same standards as conventional
diesel engines. It is also important to
note that under our current regulations,
diesel engines meeting the definition of
‘‘recreational marine engine’’ in
§ 1042.901 are not subject to catalyst
forcing standards. This approach was
applied because of factors such as the
usage patterns for recreational diesel
engines. We would expect these same
factors to apply for recreational gas
turbine engines. Thus, we are not as
concerned about a potential gas turbine
loophole for recreational engines as for
commercial engines. We also do not
have enough information at this time to
know how feasible it would be for gas
turbine engine manufacturers to comply
with the standards for recreational
diesel engines, or to accurately assess
the environmental impact of these
vessels. Nevertheless, it is clear that the
environmental impact of such small
numbers of these engines cannot be
large. Thus, at this time, we are not
proposing to apply this regulatory
change to recreational gas turbine
engines (i.e., that is gas turbine engines
installed on recreational vessels).
Nevertheless, we will continue to
investigate these engines and may
subject them to standards in the near
future.
Our diesel engine program contains a
national security exemption that
automatically exempt vessels ‘‘used or
owned by an agency of the Federal
government responsible for national
defense, where the vessel has armor,
permanently attached weaponry,
specialized electronic warfare systems,
unique stealth performance
requirements, and/or unique combat
maneuverability requirements.’’ Since it
is not our intent to prohibit naval
vessels from using turbine engines, we
are proposing to revise this provision to
automatically exempt military vessels
owned by an agency of the Federal
government responsible for national
defense powered by gas turbine engines.
We are confident that gas turbine
engines could use the same type of
aftertreatment as is projected for diesel
PO 00000
Frm 00044
Fmt 4701
Sfmt 4702
engines. The basic reactions through
which SCR reduces NOX emissions can
occur under a wide range of conditions,
and exhaust from gas turbine engines is
fundamentally similar to exhaust from
diesel engines. Moreover, since gas
turbines operate at lower air/fuel ratios
and have lower exhaust volumes, they
can actually use smaller less expensive
catalysts than diesel engines of the same
rated power. Viewed another way,
however, this requirement can be
considered to be feasible based on the
fact that the only circumstance in which
a vessel would actually need a gas
turbine engine would be for military
purposes where our national security
exemption provisions would apply. For
all other vessels, it is entirely feasible
for the vessel to be powered by a diesel
engine. In fact, that is what is being
done today.
This program for gas turbine engines
would apply to freshly manufactured
engines only. We are not proposing to
apply our marine remanufacture
program to gas turbine engines. Because
there are so few engines in the fleet, it
is not possible to know what common
rebuilding process are or whether and
how those practices would return an
existing engine to as-new condition. We
may review this approach in the future
if there is an increase in the number of
gas turbines in the fleet.
(2) Technical Amendments
The proposed regulations include
technical amendments to our motor
vehicle and nonroad engine regulations.
These changes are generally corrections
and clarifications. A large number of
these changes are the removal of
obsolete highway engine text that
applied only for past model years. Many
others are changes to the text of part
1042 to make it more consistent with
the language of our other recently
corrected nonroad parts. The last large
category of changes includes those
related to the test procedures in part
1065. See the memorandum in the
docket entitled ‘‘Technical
Amendments to EPA Regulations’’ for a
full description of these changes.126
(3) Locomotives Operating Outside of
the United States
Locomotive manufacturers have
raised an issue similar to the issue of
on-off technologies discussed in Section
VI.A.3. They have objected in the past
to EPA’s refusal to certify engine
designs that increase NOX emissions
when the locomotive is operating in
126 See ‘‘Proposed Technical Amendments to EPA
Regulations,’’ EPA memorandum from Alan Stout,
in the docket for this proposed rule, Docket No.:
EPA–HQ–OAR–2007–0121.

Mexico, even though the engine design
would reverse the adjustment to allow
the locomotive to conform to NOX
emissions standards when it returns to
the United States. Engine manufacturers
have wanted to use such engine designs
to improve fuel consumption by
readjusting injection timing while the
locomotive is operating in Mexico.
In our recent locomotive rulemaking,
we responded to these manufacturer
concerns by noting that we have
‘‘prohibited such AECDs because of
concerns over their potential adverse
impacts on U.S. air quality,’’
recognizing that ‘‘emissions that occur
outside the territorial boundaries of the
U.S. can impact air quality within the
U.S.’’ Since we also committed to
reconsider the issue more broadly in
this current rulemaking, we are
requesting comment on whether we
should allow manufacturers to certify
such engine designs.
In particular, we are requesting
comment on what conditions we should
set if we allow such designs. For
example, should we approve the design
only if it was calibrated to remain in the
low-NOX mode until it was at least 200
miles away from the U.S. border?
Should we allow such designs if they
would conflict with Mexican law?
Should we also consider operation in
Canada or Central American countries?
Commenters should also address the
degree to which such designs would be
tamper-proof and whether special
recordkeeping or reporting requirements
should be included. Finally,
commenters should also address how
EPA should respond if such a
locomotive was found to be operating in
the U.S. in the high-NOX configuration
and such high-NOX operation was not
caused by tampering. Should it be
treated merely as a defect that must be
reported, or should it be treated as
different violation, e.g., introduction
into commerce of an engine not in
substantial conformance to its
certificate?
(4) Stockpiling of Model Year 2009
Highway Engines
EPA is also proposing to add language
in part 85, applicable to heavy-duty
motor vehicles and heavy-duty engines
used in motor vehicles, which codifies
that the ‘‘stockpiling’’ of engines to
avoid compliance with later, more
stringent emission standards is
considered a circumvention of the Clean
Air Act and is prohibited. The proposed
provisions are consistent with existing
stockpiling provisions for nonroad
engines and equipment in part 1068 and
are intended to codify the prohibition
for heavy-duty motor vehicles and
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
heavy-duty engines. Stockpiling of
engines is the practice of keeping in
inventory more engines than a
manufacturer normally keeps in
inventory, in particular when those
engines do not meet the more stringent
standards. EPA believes this prohibition
is necessary to ensure that engine and
vehicle manufacturers comply with the
same compliance ‘‘clock’’ while
allowing for minimum but necessary
flexibility during the transition of model
years. We recognize there will be the
need for some market transition when
standards change but believe this
regulatory clarification will help
provide guidance to the vehicle and
engine manufacturers.
EPA is proposing to add this language
to clarify EPA’s longstanding policy that
considers stockpiling to be a
circumvention of the Act, including the
terms of section 203(a)(1). During and
after the transition to the 2007 heavyduty diesel emission standards EPA met
with several manufacturers to
understand their production plans and
their concerns regarding all
manufacturers’ timely compliance with
the new emission standards. EPA has
begun to have similar discussions with
and inquiries from manufacturers for
the transition to the 2010 model year.127
The Agency has also been conducting
some analysis of market practices. Given
this experience EPA believes it
appropriate to clearly set forth the
stockpiling prohibition.
Therefore, for example, an engine
manufacturer who sells engines to a
vehicle manufacturer cannot sell
engines in a current model year for the
purpose of having them installed in a
future model year’s vehicles when the
engine sale is beyond that required to
meet normal production lead time
requirements. Likewise, a vehicle
manufacturer cannot order or install
engines from a prior model year when
the number of such engines exceeds that
needed to meet normal inventory
requirements. This will prevent vehicle
manufacturers from avoiding
compliance with emission requirements
which would otherwise apply during
the model year of the vehicle. Other
indicators that illegal stockpiling may
have occurred include build up of
excessive inventory or volume of
engines prior to a future model year that
is inconsistent with historic production
volumes, actions to create a market for
the sale of engines meeting earlier
127 For example, EPA received a request for
guidance from Volvo on April 13, 2009 seeking
clarification on the transition to the 2010 model
year standards for both vehicle and engine
manufacturers. Docket No.: EPA–HQ–OAR–2007–
0121.

standards in a future year, and the sale
of previous model year engines
representing a disproportionate amount
of total sales in the subsequent model
year. If emissions standards for the
engine do not change in a given model
year, a manufacturer may continue to
install engines from a previous model
year without restriction.
EPA will also consider many factors
in assessing whether an engine
manufacturer has caused or aided in the
prohibited act of stockpiling. For
example, contractual (or otherwise
established) business relationships of
those persons involved in producing
and/or selling new engines and vehicles
could be evidence of the ability of the
person to cause a violation. In addition,
we would consider the particular efforts
or influence of the alleged violator
contributing to, leading to, or resulting
in the prohibited act. On the other hand,
we would also consider a person’s
efforts to prevent such a violation as
evidence that they did not cause the
violation.
E. Coast Guard’s Marine Vessel
Certification Program
The U.S. Department of
Transportation Maritime Administration
(MARAD) oversees the Maritime
Security Program (MSP) established by
the Maritime Security Act of 1996 and
reauthorized by the Maritime Security
Act of 2003 (MSA). The MSA requires
that the Secretary of Transportation, in
consultation with the Secretary of
Defense, establish a fleet of active,
commercially viable and militarily
useful vessels to meet national defense
and other security requirements and
maintain a U.S. presence in
international commercial shipping. The
fleet consists of privately-owned, U.S.flagged vessels known as the Maritime
Security Fleet (MSF). 46 U.S.C. 53102
outlines that vessels complying with
applicable international agreements and
associated guidelines are eligible for a
certificate of inspection from Coast
Guard, and thus inclusion in the MSF.
The requirements of the MSP may
have created confusion for owners of
non-U.S.-flagged vessels regarding their
obligation to also comply with EPA’s
domestic marine diesel engine emission
standards at the time they re-flag for
inclusion in the MSF. We want to
remind vessel owners that the MSA
does not preempt the Clean Air Act or
alleviate their obligation to comply with
EPA’s marine diesel engine program, or
any other EPA requirements that apply
to marine vessels. Each U.S.-flagged
vessel must comply with all of EPA’s
domestic standards, regardless of
whether the vessel was flagged in the
E:\FR\FM\28AUP2.SGM

U.S. upon original delivery into service.
Specifically, model year 2004 and later
marine diesel engines installed on these
vessels must be covered by a certificate
of conformity issued under 40 CFR Part
94 or 40 CFR Part 1042, unless covered
by a specific exemption or exclusion in
those regulations.
Owners that wish to re-flag a vessel
for U.S. service in the MSF should
contact EPA to determine the specific
compliance requirements that must be
met.
VII. Costs and Economic Impacts
In this section, we present the
projected cost impacts and cost
effectiveness of the coordinated
emission control strategy for oceangoing vessels. We also present our
analysis of the economic impacts of the
coordinated strategy, which consists of
the estimated social costs of the program
and how those costs will likely be
shared across stakeholders. The
projected benefits and benefit-cost
analysis of the coordinated strategy are
presented in Section VIII.
We estimate the costs of the
coordinated strategy to be about $1.85
billion in 2020, increasing to $3.11
billion in 2030.128 Of the 2020 costs,
nearly 89 percent or $1.64 billion are
attributable to the ECA fuel sulfur
provisions. The total operational costs
are estimated to be $1.82 billion in
2020. The costs to apply engine controls
to U.S.-flagged vessels are expected to
be $31.9 million in 2020, increasing to
$47.4 million in 2030 as more ships are
built to comply with Clean Air Act
(CAA) Tier 3 NOX limits. All costs are
presented in 2006 U.S. dollars.
When attributed by pollutant, at a net
present value of 3 percent from 2010
through 2040, the NOX controls are
expected to cost about $510 per ton of
NOX reduced, SOX controls are expected
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
128 These total estimated costs are slightly
different than those reported in the ECA proposal,
because the ECA proposal did not include costs
associated with the Annex VI existing engine
program, Tier II, or the costs associated with
existing vessel modifications that may be required
to accommodate the use of lower sulfur fuel.
Further, the cost totals presented in the ECA
package included Canadian cost estimates.
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
to cost about $930 per ton of SOX
reduced, and the PM controls are
expected to cost about $7,950 per ton of
PM reduced ($500, $920, and $7,850 per
ton of NOX, SOX, and PM respectively,
at a net present value of 7 percent over
the same period.) These costs are
comparable to our other recentlyadopted mobile source programs, and
are one of the most cost-effective
programs in terms of NOX and PM when
compared to recent mobile and
stationary programs. The coordinated
strategy also provides very cost-effective
SOX reductions comparable to the
Heavy-Duty Nonroad diesel rulemaking.
The social costs of the proposed
program are estimated to be
approximately $3.1 billion in 2030. The
impact of these costs on society is
estimated to be minimal. For example,
we estimate the cost of shipping a 20foot container on the Pacific route, with
1,700 nm of operation in the ECA,
would increase by about $18, or less
than 3 percent. Similarly, the price of a
seven-day Alaska cruise that operates
mainly in the ECA is expected to
increase by about $7 per day.
The estimated costs presented in this
section are for the entire coordinated
strategy, including those requirements
that are the subject of this proposal and
those that are associated with the
proposed ECA designation. Table VII–1
sets out the different components of the
coordinated strategy and our ECA
designation package, for 2020. The costs
of the coordinated strategy consists of
the costs associated with the MARPOL
Annex VI global standards that we are
implementing through APPS, some of
which we are also adding to our CAA
emission control program for U.S.
vessels (Tier 2 and Tier 3 NOX emission
control hardware for U.S. vessels;
operating costs for the Tier 2 NOX
requirements; controls for existing
vessels; certain compliance
requirements). Also included are the
costs associated with the U.S. portion of
the ECA package (Tier 3 hardware and
operating costs; fuel sulfur hardware
and operating costs). The costs
associated with the Canadian portion of
PO 00000
Frm 00046
Fmt 4701
Sfmt 4702
the ECA package are not included in the
costs of the coordinated strategy.
Note that, with regard to hardware
costs, the coordinated strategy includes
the entire cost for new U.S. vessels to
comply with the Tier 3 NOX standards
and ECA fuel limits, even though some
of the benefits from using these
emission control systems will occur
outside the United States. Conversely,
we do not include any new vessel Tier
3 or fuel hardware costs for foreign
vessels that operate in U.S. waters even
though a significant share of the benefits
of the coordinated strategy will arise
from foreign vessels that comply with
the ECA engine and fuel sulfur limits
while operating within the U.S. ECA.
An alternative approach would be to
allocate a portion of hardware costs of
complying with the Tier 3 NOX
standards and the fuel sulfur limits to
the coordinated strategy. For example,
analysis of MARAD port entrance data
shows that about 30 percent of the
vessels that enter U.S. ports account for
about 75 percent of the vessel entrances.
This suggests it may be reasonable to
allocate the hardware costs for 30
percent of the new foreign vessels to the
coordinated strategy. Similarly, it may
be reasonable to discount the share of
estimated hardware costs included in
the coordinated strategy costs for those
U.S. vessels that do not operate
primarily between two U.S. ports. We
request comment on the allocation of
hardware costs and on whether the U.S.
should adopt the alternative approach
described above or some other method
to allocate these costs.
The regulatory changes proposed for
Category 1 and 2 engines are not
included in this cost analysis as they are
intended to be compliance flexibilities
and not result in increased compliance
costs. Similarly, the technical
amendments proposed for other
engines, would not have significant
economic impacts and are therefore not
addressed here. Finally, compliance
costs for gas turbine engines are not
addressed separately because they
would be similar to those for diesel
marine engines.

This cost analysis relies on a number
of assumptions about the prices of
various engine and fuel hardware
components, as well as fuel
consumption, the number of affected
vessels, and their operation. We seek
comment on all aspects of this analysis,
including all of these assumptions and
the methodology we used to estimate
the costs of the program.

A. Estimated Fuel Costs
Although the ECA fuel sulfur limits
are not part of this proposal, they are
part of the coordinated strategy and we
are including them in this cost analysis.
However, we consider the costs and
benefits of ECA designation in this
proposal, as they are part of our
coordinated strategy for ocean-going
vessels.
Current regulations impose a sulfur
limitation of 15 ppm for distillate fuels
produced at refineries in the U.S. The
coordinated strategy would impose no
additional costs for refiners in the U.S.
and would actually allow additional
flexibility. Specifically, we are
proposing to allow distillate fuel to have
up to 1,000 ppm sulfur for use in OGVs.
The ECA fuel requirements will impose
a cost to the ship owners. This section
presents estimates of the cost of
compliance with the 1,000 ppm sulfur
limit in the U.S. ECA.
Distillate fuel will likely be used to
meet the 1,000 ppm fuel sulfur limit,
beginning in 2015. As such, the primary
cost of the fuel sulfur limit for ship
owners will be that associated with
switching from heavy fuel oil to highercost distillate fuel. Some engines
already operate on distillate fuel and
would not be affected by fuel switching
costs. However, distillate fuel costs may
be affected by the need to further refine
the distillate fuel to meet the 1,000 ppm
sulfur limit.
To investigate these effects, studies
were performed on the impact of a
North American ECA on global fuel
production and costs, to inform the
application for such ECA.129 These
studies were performed prior to the ECA
being defined; thus, we picked a
maximum distance boundary to ensure
a conservative cost analysis.
Specifically, we used the total fuel
consumption in the U.S. and Canada

exclusive economic zones.130 As a
result, the modeled fuel volumes are
higher than would be affected by the
proposed ECA. The studies are relevant
to this regulation as well, since they
estimate the cost of 1,000 ppm sulfur
fuel for ships operating in such ECA
zones.
To assess the effect on the refining
industry of the imposition of a 1,000
ppm sulfur limit on fuels operating in
the ECA, we needed to first understand
and characterize the fuels market.
Research Triangle Institute (RTI) was
contracted to conduct a fuels study
using an activity-based economic
approach. The study established
baseline bunker fuel demand, projected
a growth rate for bunker fuel demand,
and established future bunker fuel
demand volumes.131 These volumes
then became the input to the World Oil
Refining Logistics and Demand
(WORLD) model to evaluate the effect of
an ECA on fuel cost.
The WORLD model was run by Ensys
Energy & Systems, the owner and
developer of the refinery model. The
WORLD model is the only such model
currently developed for this purpose
and was developed by a team of
international petroleum consultants. It
has been widely used by industries,
government agencies, and Organization
of the Petroleum Exporting Countries
(OPEC) over the past 13 years, including
the Cross Government/Industry
Scientific Group of Experts, established
to evaluate the effects of the different
fuel options proposed under the
revision of MARPOL Annex VI. The
model incorporates crude sources,
global regions, refinery operations, and
world economics. The results of the
WORLD model have been comparable to
other independent predictions of global
fuel, air pollutant emissions and
economic predictions.
The WORLD model was run for 2020,
in which the control case included a
fuel sulfur level of 1,000 ppm in the
U.S. The baseline case was modeled as
‘‘business as usual’’ in which ships
continue to use the same fuel as today.
Because of the recent increases and
fluctuations in oil prices, we had
additional WORLD model runs
conducted. For these runs, we used new
reference case and high oil price

this analysis, the U.S. included the lower
48 contiguous states and southeastern Alaska.

estimates that were recently released by
the U.S. Energy Information
Administration (EIA). In addition to
increased oil price estimates, the
updated model accounts for increases in
natural gas costs, capital costs for
refinery upgrades, and product
distribution costs.
Because only a small portion of global
marine fuel is consumed in the ECA, the
overall impact on global fuel production
is small. Global fuel use in 2020 by
ships is projected to be 500 million
metric tonnes/yr. Of this amount, 90
million metric tonnes of fuel is used for
U.S./Canadian trade, or about 18
percent of total global fuel use. In the
proposed ECA, less than 20 million
metric tonnes of fuel will be consumed
in 2020, which is less than 4 percent of
total global marine fuel use. Of the
amount of fuel to be consumed in the
proposed ECA in 2020, about 4 million
metric tonnes of distillate will be
consumed in the Business as Usual
(BAU) case, which is about 20 percent
of the amount of total fuel to be
consumed in the proposed ECA.
There are two main components to
projected increased marine fuel cost
associated with the ECA. The first
component results from shifting from
operation on residual fuel to operation
on higher cost distillate fuel. This is the
dominant cost component. However,
there is also a small cost associated with
desulfurizing the distillate to meet the
1,000 ppm sulfur standard in the ECA.
Based on the WORLD modeling, the
average increase in costs associated with
switching from marine residual to
distillate will be $145 per metric
tonne.132 This is the cost increase that
will be borne by the shipping
companies purchasing the fuel. Of this
amount, $6 per metric tonne is the
increase in costs associated with
distillate desulfurization.
Table IV– summarizes the fuel cost
estimates with and without an ECA. In
the baseline case, fuel volumes for
operation are 18% marine gas oil
(MGO), 7% marine diesel oil (MDO),
and 75% IFO. Weighted average
baseline distillate fuel cost is $462/
tonne. In the ECA, all fuel volumes are
modeled as MGO, at $468/tonne.
132 Note that distillate fuel has a higher energy
content, on a per ton basis, than residual fuel. As
such, there is an offsetting cost savings, on a per
metric ton basis, for switching to distillate fuel.
Based on a 5 percent higher energy content for
distillate, the net equivalent cost increase is
estimated as $123 for each metric ton of residual
fuel that is being replaced by distillate fuel.

The increased cost of distillate
desulfurization is due both to additional
coking and hydrotreating capacities at
refineries. Cokers crack residual blends
in IFO bunker fuel into distillates, using
heat and residence time to make the
conversion. The process also produces
useful byproducts such as petroleum
coke and off gas. The WORLD model
did not use hydrocracking technology to
convert residual fuels into distillates for
either the reference or high price crude
cases. Because of the higher capital and
operating costs of hydrocrackers, the
WORLD model favored the use of
coking units. As such, the WORLD
model assumed that cokers would
convert the residual blendstocks in
Intermediate Fuel Oil grades to
distillates. The model added coking
processes to refineries located in the
U.S. and, to a lesser extent, to refiner
regions outside of the U.S. Specifically,
the model added one additional coking
unit with a capacity of 30 thousand
barrels per stream day (KBPSD), and one
to two hydrocracking units representing
50 and 80 KBPSD additional capacity.
The WORLD model also added new
conventional distillate hydrotreating
capacity to lower the sulfur levels for
the marine distillate fuel, in addition to
the existing slack distillate
hydrotreating capacity that existed in
refiner regions for these fuels. In
addition, the model used lighter crudes
and adjusted operating parameters in
refineries. This had the effect of
increasing the projected production of
lower sulfur distillate fuels in lieu of
adding distillate hydrotreating capacity.
The model elected to use lower sulfur
crudes and used operational
adjustments. Higher capital and
operating costs of new units under the
high-priced crude scenario favored use
of existing refinery capacity made
available from lower global refiner
utilizations.
B. Estimated Engine Costs
To quantify the cost impacts
associated with the coordinated
strategy, we estimated the hardware and
operational costs to U.S.-flagged ships,
as well as affected foreign-flagged ships.
The hardware costs are only applied to
VerDate Nov<24>2008

Jkt 217001
U.S.-flagged vessels, and include those
associated with the CAA Tier 2 and Tier
3 NOX standards, the Annex VI existing
engine program, and the use of lower
sulfur fuel. Tier 2 hardware costs
consist of changes to the engine block
and the migration from mechanical fuel
injection to common rail fuel injection
systems. Tier 3 hardware costs include
engine modifications, the migration
from mechanical fuel injection to
common rail fuel injection systems, and
the installation of Selective Catalytic
Reduction (SCR). Hardware costs
associated with the use of lower sulfur
fuel are from applying additional tanks
and equipment to enable a vessel to
switch from residual fuel to lower sulfur
fuel. These equipment costs were
applied to those new vessels that may
need additional hardware, and also
include the estimated cost of retrofitting
the portion of the fleet that may require
additional hardware to accommodate
the use of lower sulfur fuel in 2015. The
hardware costs also include a per engine
cost of $10,000 associated with the
proposed requirement to test each
production engine (§ 1042.302). These
are the sole engine hardware costs
specifically attributable to our Clean Air
Act rule. The programmatic changes
under consideration for Category 1 and
2 engines (see Section VI.C, above),
would not impose compliance costs but
instead are intended to facilitate
compliance with both Annex VI and our
Clean Air Act requirements for those
engines.
Although we have developed
hardware cost estimates for all ships
that may enter U.S. ports, we do not
believe that it is appropriate to attribute
all of these costs to emissions
reductions in the U.S. Clearly, this
technology will be used globally and
will result in emissions reductions in
many other countries. At the same time,
some amount of the hardware costs
should be attributed to the emissions
reductions achieved in the U.S. To
address these considerations, we
include the hardware costs for only
U.S.-flagged vessels in our cost
estimates, and present the hardware
costs for foreign-flagged vessels as a
separate analysis. The operational costs,

which represent the majority of the
costs to ships, are included in our cost
totals for both U.S.- and foreign-flagged
vessels.
The operational costs were applied to
both U.S.- and foreign-flagged vessels
and include additional operational costs
associated with the applicable NOX
limits and the use of lower sulfur fuel.
The operational costs for NOX controls
consist of the additional fuel required
due to an estimated two percent fuel
penalty associated with the use of
technologies to meet CAA Tier 2 and
global Tier II NOX standards, and the
use of urea for ships equipped with an
SCR unit to meet CAA Tier 3 and global
Tier III NOX standards. The operational
costs associated with the use of lower
sulfur fuel include both the differential
cost of using lower sulfur fuel that
meets ECA standards instead of using
marine distillate fuel, and the
differential cost of using lower sulfur
fuel that meets ECA standards instead of
using residual fuel.
To assess the potential cost impacts,
we must understand (1) the makeup of
the fleet of ships expected to visit the
U.S. when these requirements go into
effect, (2) the emission reduction
technologies expected to be used, and
(3) the cost of these technologies.
Chapter 5 of the draft RIA presents this
analysis in greater detail. The total
engine and vessel costs associated with
the coordinated strategy are based on a
cost per unit value applied to the
number of affected vessels. Operational
costs are based on fuel consumption
values determined in the inventory
analysis (Section 5.2). This section
discusses a brief overview of the
methodology used to develop the
hardware and operational costs, and the
methodology used to develop a fleet of
future vessels to which these hardware
and engineering costs were applied.
(1) Methodology
To estimate the hardware costs to
ships that may be affected by the
coordinated strategy, we used an
approach similar to that used to
estimate the emissions inventory.
Specifically, the same inputs were used
to develop a fleet of ships by ship type

and engine type that may be expected to
visit U.S. ports through the year 2040.
In order to determine the cost of
applying emission reduction technology
on a per vessel basis, ICF International
was contracted by the U.S. EPA to
conduct a cost study of the various
compliance strategies expected to be
used to meet the new NOX standards
and fuel sulfur requirements.133 ICF was
instructed to develop cost estimates
covering a range of vessel types and
sizes, which could be scaled according
to engine speed and power to arrive at
an estimated cost per vessel.
A series of both slow-speed and
medium-speed engine configurations
were selected and used to provide an
understanding of the costs of applying
emission control technologies
associated with the coordinated
strategy. The engine configurations were
selected based on a review of 2005 U.S.
Army Corps of Engineers ‘Entrances and
Clearances’ data which was used to
determine the characteristics of engines
on those vessels that call on U.S. ports
most frequently. This data represents a
broad range of propulsion power for
each engine type (slow and medium
speed engines). The costs developed for
these engine configurations were used
to develop a $/kW value that could be
applied to any slow or medium speed
engine. Using the average propulsion
power by ship type presented in the
inventory analysis, the per-vessel
hardware costs were then applied to the
estimated number of applicable vessels
built after the standards take effect.
(a) Hardware Costs
The hardware cost estimates include
variable costs (components, assembly,
and the associated markup) and fixed
costs (tooling, research and
development, redesign efforts, and
certification). Hardware costs associated
with the Annex VI existing engine
standards were applied to the portion of
existing U.S.-flagged vessels built
between 1990 and 1999 expected to be
subject to these standards (engines with
a per-cylinder displacement of at least
90 liters and a power output of over
5,000 kW) in 2011 when the standards
go into effect. These costs were applied
over a five year period beginning in
2011 where 20 percent of the total
subject fleet was estimated to undergo
service each year. The existing engine
program fixed costs were phased in over
a five year period beginning in 2010 and
applied on a per-vessel basis.

Hardware costs associated with the
CAA Tier 2 program were applied to all
new U.S.-flagged vessels beginning in
the year 2011 when the standards take
effect. The fixed costs associated with
Tier 2 standards are expected to be
incurred over a five year period;
however, as the Tier 2 standards take
effect in 2011, it was assumed that
manufacturers are nearing the end of
their research and development. In
order to capture all of these costs, all
fixed costs that would have been
incurred during that five year phase-in
period were applied in the year 2010.
Hardware costs associated with Tier 3
were estimated for U.S. vessels and
were applied as of 2016. Because of the
global scope of the Tier III standards,
and the fact that other ECAs exist today
and more may exist in the future, we do
not include hardware costs for Tier III
emission controls on foreign-flagged
vessels. However, for completeness,
Section 5.2 of the draft RIA presents
these hardware cost estimates
separately. The fixed costs associated
with Tier 3 were phased in over a five
year period beginning in 2011.
Hardware costs associated with the
use of lower sulfur fuel are estimated
separately for both new and existing
vessels that may require additional
hardware to accommodate the use of
lower sulfur fuel. The costs expected to
be incurred by U.S.-flagged vessels are
included in the total cost of the
coordinated strategy, while the cost to
foreign-flagged vessels is presented as a
separate analysis. The fuel sulfur
control related hardware costs for new
vessels begin to apply in 2015, while all
retrofit costs are expected to be incurred
by 2015 and as such are applied in this
year. The fixed costs for both new and
existing vessels that may require
additional hardware to accommodate
the use of lower sulfur fuel are applied
on a per-vessel basis and are phased in
over a five year period beginning as of
2010.
consumption penalty of 2 percent (see
Chapter 4 of the draft RIA) The two
percent fuel penalty estimate is based
on the use of modifications to the fuel
delivery system to achieve Tier II NOX
reductions, and does not reflect the
possibility that there may be other
technologies available to manufacturers
that could offset this fuel penalty.
Additionally, Tier III will provide the
opportunity to re-optimize engines for
fuel economy when using
aftertreatment, such as SCR, to provide
NOX reductions similar to the
compliance strategy for some heavyduty truck manufacturers using urea
SCR to meet our 2010 truck standard.
The differential cost of using lower
sulfur fuel is discussed above in Section
VII.A of this Preamble. The estimated
urea cost associated with the use of Tier
III SCR is derived from a urea dosage
rate that is 7.5 percent of the fuel
consumption rate.
Operating costs per vessel vary
depending on what year the vessel was
built, e.g., vessels built as of 2016 will
incur operating costs associated with
the use of urea necessary when using
SCR as a Tier III NOX emission control
technology, while vessels built prior to
2016 do not use urea but will incur
operating costs associated with the
differential cost of using lower sulfur
fuel. Further, we have assumed vessels
built as of 2011 that meet Tier II
standards will incur a 2 percent fuel
consumption penalty; see Table 5–31 of
the draft RIA for further details on fuel
costs and fuel volumes. In addition,
vessels built as of 2016 that meet Tier
III NOX standards while traveling in an
ECA are still required to at least meet
Tier II NOX standards outside of an ECA
and will continue to incur the
associated fuel penalty. Therefore, an
estimated fleet had to be developed over
a range of years, and provide a breakout
of ships by age in each year.
(b) Operational Costs
The operational costs estimated here
are composed of three parts: (1) The
estimated increase in fuel consumption
expected to occur with the use of Tier
II technologies on U.S.- and foreignflagged vessels, (2) the differential cost
of using lower sulfur fuel applicable for
both U.S.- and foreign-flagged vessels,
and (3) the use of urea with SCR as a
Tier III NOX emission reduction
technology on both U.S.- and foreignflagged vessels. The fuel consumption
values associated with Tier II and Tier
III standards were determined in the
inventory analysis (see Chapter 3 of the
draft RIA), with an estimated Tier II fuel
There are currently no available
estimates of the number of ships that
may visit U.S. ports in the future or
comprehensive engine sales predictions.
Therefore, to develop the costs
associated with the coordinated
strategy, an approximation of the
number of ships by age and engine type
that may visit U.S. ports in the future
was constructed. To characterize the
fleet of ships visiting U.S. ports, we
used U.S. port call data collected in
2002 for the inventory port analysis (see
Chapter 3 of the draft RIA) which
included only vessels with C3 engines
where the engine size and type was

identified.134 We used this data with the
growth rates developed in the inventory
analysis to estimate how many ships, by
ship type and engine type, would visit
U.S. ports in future years. Due to the
long life of these vessels, and the fact
that there has been no significant event
that would have changed the
composition of the world fleet since this
baseline data was taken, it is reasonable
to use 2002 data as the basis for
modeling the future fleet upon which to
base hardware cost estimates. An
analysis is presented in Section 5.1.2.2
of Chapter 5 of the draft RIA which
confirms the reasonableness of this
assumption using 2007 MARAD data.
The research performed for this cost
analysis was based on differentiating
between slow-speed diesel (SSD) and
medium-speed diesel (MSD) engines,
and separate $/kW values were
developed for each of these engine
types. The separation by engine type
was also necessary to allow for the use
of the age distribution formula
determined by the inventory analysis
(see Chapter 3 of the draft RIA) to
determine how many vessels the
hardware and/or operational costs are
applicable to in each year.
The ship type information gathered
from this baseline data, for the purposes
of both this analysis and the inventory,
was categorized into one of the
following ship types: Auto Carrier, Bulk
Carrier, Container, General Cargo,
Miscellaneous, Passenger, Refrigerated
Cargo (Reefer), Roll-On Roll-Off (RoRo),
and Tankers. Average engine and vessel
characteristics were developed from the
baseline data, and these values were
used to represent the characteristics of
new vessels used in this cost analysis
(see Chapter 3 of the draft RIA).
Estimated future fleets were developed
by ship type and engine type through
the year 2040 for both new and existing
vessels and both U.S.- and foreignflagged vessels. Hardware costs were
applied on a per-vessel basis.
Although most ships primarily
operate on residual fuel, they typically
carry some amount of distillate fuel as
well. Switching to the use of lower
sulfur distillate fuel is the compliance
strategy assumed here to be used by
both new and existing ships in 2015
when the new lower sulfur fuel
standards go into effect. To estimate the
potential cost of this compliance
strategy, we evaluated the distillate
storage capacity of the current existing
fleet to estimate how many ships may

medium speed engines where that information was
not explicitly available, 2-stroke engines were
assumed to be slow speed, where 4-stroke engines
were assumed to be medium speed.

require additional hardware to
accommodate the use of lower sulfur
fuel. We performed this analysis on the
entire global fleet listed in Lloyd’s
database as of 2008.135 Of the nearly
43,000 vessels listed, approximately
20,000 vessels had provided Lloyds
with fuel tankage information, cruise
speed, and propulsion engine power
data. Using this information, we were
able to estimate how far each vessel
could travel on its existing distillate
carrying capacity.
In order to determine if the current
distillate capacity of a particular ship
was sufficient to call on a U.S. ECA
without requiring additional hardware,
we evaluated whether or not each ship
could travel 1,140 nm, or the distance
between the Port of Los Angeles and the
Port of Tacoma. This distance was
selected because it represents one of the
longer trips a ship could travel without
stopping at another port, and should
overestimate the number of vessels that
would require such a modification. The
resulting percentages of ships estimated
to require a retrofit were then applied to
the number of existing ships in the 2015
fleet to estimate the total cost of this
compliance strategy for existing ships
built prior to 2015. The same
percentages were also applied to all new
ships built as of 2015 to determine the
number of ships that may require
additional hardware and estimate the
cost of this compliance strategy for new
vessels.
(3) NOX Reduction Technologies
(a) Tier 2
Most engine manufacturers are
expected to be able to meet Tier 2 NOX
standards using engine modifications.
This cost estimate includes the
hardware costs associated with the use
of retarded fuel injection timing, higher
compression ratios, and better fuel
distribution. There are no variable costs
associated with the engine
modifications as the changes are not
expected to require any additional
hardware. Some engines may also be
equipped with common-rail fuel
systems instead of mechanical fuel
injection to meet Tier 2 NOX standards.
It is expected that approximately 75
percent of SSD and 30 percent of MSD
engines will get this modification for
Tier 2. The Tier 2 hardware costs
developed here include the costs of the
migration of some engines to commonrail fuel systems. It was also estimated
that these technologies may increase
fuel consumption by up to 2 percent;
this fuel penalty is included in the Tier
135 https://www.sea-web.com

Frm 00051
Fmt 4701

2 operational costs. Tier 2 hardware
costs included in the total estimated
cost of the coordinated strategy are only
associated with U.S.-flagged vessels;
operational costs are applied to both
U.S.-and foreign-flagged vessels.
(b) Tier 3
Tier 3 NOX standards are
approximately 80 percent below Tier 1
NOX standards, and are likely to require
exhaust aftertreatment such as SCR. ICF
performed a detailed cost analysis for
the U.S. EPA that included surveying
engine and emission control technology
manufacturers regarding these advanced
technology strategies and their potential
costs. Tier 3 NOX standards are
projected to be met through the use of
SCR systems. While other technologies
such as EGR or those that include
introduction of water into the
combustion chamber either through
fumigation, fuel emulsions, or direct
water injection may also enable Tier 3
compliance, we assume they will only
be selected if they are less costly than
SCR. Therefore, we have based this
analysis on the exclusive use of SCR.
(c) Engine Modifications
In addition to SCR, it is expected that
manufacturers will also use compound
or two-stage turbocharging as well as
electronic valving to enhance
performance and emission reductions to
meet Tier 3 NOX standards. Engine
modifications to meet Tier 3 emission
levels will include a higher percentage
of common-rail fuel injection coupled
with two-stage turbocharging and
electronic valving. Engine
manufacturers estimate that nearly all
SSD and 80 percent of MSD engines will
use common-rail fuel injection. Two
stage turbocharging will most likely be
used on least 70 percent of all engines
required to meet Tier 3 emission levels.
Electronically- (hydraulically) actuated
intake and exhaust valves for MSD and
electronically-actuated exhaust valves
for SSD are necessary to accommodate
two-stage turbocharging. Additionally,
the remaining SSD engines still using
mechanical injection (approximately 25
percent mechanically-controlled, and 75
percent electronically-controlled) are
expected to migrate to common rail for
Tier 3, while an additional 40 percent
of MSD engines are expected to receive
common rail totaling approximately 80
percent of all MSD engines. The engine
modification variable costs were applied
to all new U.S.-flagged vessels equipped
with either SSD or MSD engines. Costs
to foreign-flagged vessel expected to
visit U.S. ports are presented as a
separate analysis in Chapter 5 of the
draft RIA, and are not included in the

total estimated cost of the coordinated
strategy.
(4) SOX/PM Emission Reduction
Technology
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
In addition to Tier 3 NOX standards,
the IMO ECA requirements also include
lower fuel sulfur limits that will result
in reductions in SOX and PM. Category
3 marine engines typically operate on
heavy fuel oil with a sulfur content of
2.7 percent, therefore significant SOX
and PM reductions will be achieved
using distillate fuels with a sulfur
content of 0.1 percent. This cost
analysis is based on the assumption that
vessel operators will operate their
engines using lower sulfur fuel in the
proposed ECA. We believe fuel
switching will be the primary
compliance approach; fuel scrubbers
would be used in the event that the
operator expected to realize a cost
savings and are not considered in this
analysis. In some cases, additional
capacity and equipment to
accommodate the use of lower sulfur
fuel may need to be installed on a
vessel. The potential costs due to these
additional modifications applied to new
ships as well as retrofits to any existing
ships are discussed here, and these
hardware costs are included as part of
the total cost of this coordinated
program.
Although most ships operate on heavy
fuel oil, they typically carry small
amounts of distillate fuel. Some vessel
modifications and new operating
practices may be necessary to use lower
sulfur distillate fuels on vessels
designed to operate primarily on
residual fuel. Installation and use of a
fuel cooler, associated piping, and
viscosity meters to the fuel treatment
system may be required to ensure
viscosity matches between the fuel and
injection system design. While there are
many existing ships that already have
the capacity to operate on both heavy
fuel oil and distillate fuel and have a
separate fuel tank systems to support
each type of fuel, some ships may not
have sufficient onboard storage
capacity. If a new or segregated tank is
desired, additional equipment for fuel
delivery and control of these systems
may be required.
(5) NOX and SOX Emission Reduction
Technology Costs
(a) NOX Emission Reduction
Technology
The costs associated with SCR
include variable and fixed costs. SCR
hardware costs include the reactor,
dosage pump, urea injectors, piping,
bypass valve, an acoustic horn or a

Jkt 217001
cleaning probe, the control unit and
wiring, and the urea tank (the size of the
tank is based on 250 hours of normal
operation when the ship is operating in
the ECA and the SCR system is
activated.) The size of the tank is
dependent on the frequency with which
the individual ship owner prefers to fill
the urea tank. The methodology used
here to estimate the capacity of the SCR
systems is based on the power rating of
the propulsion engines only. Auxiliary
engine power represents about 20
percent of total installed power on a
vessel; however, it would be unusual to
operate both propulsion and auxiliary
engines at 100 percent load. Typically,
ships operate under full propulsion
power only while at sea when the SCR
is not operating; when nearing ports, the
auxiliary engine is operating at high
loads while the propulsion engine is
operating at very low loads.
In this analysis, we determined the
average number of hours a ship would
spend calling on a U.S. port: If the call
was straight in and straight out at 200
nm, the average time spent was slightly
over 35 hours. If the distance travelled
was substantial, such as from the Port of
Los Angeles to the Port of Tacoma, or
1140 nm, the average time spent
travelling was approximately 75 hours.
Therefore, the size of the tanks and
corresponding $/kW values estimated
here to carry enough urea for 250 hours
of continuous operation may be an
overestimate. Based on 250 hours of
operation, a range of urea tank sizes
from 20 m3 to approximately 256 m3
was determined for the six different
engine configurations used in this
analysis.
To understand what impacts this may
have on the cargo hauling capacity of
the ship, we looked at the ISO standard
containers used today. Currently, over
two-thirds of the containers in use today
are 40 feet long, total slightly over 77 m3
and are the equivalent of two TEU.136
The urea tank sizes estimated here
reflect a cargo equivalence of 0.5–2
TEUs, based on a capacity sufficient for
250 hours of operation. The TEU
capacity of container ships, for example,
continues to increase and can be as high
as 13,000 TEUs;137 while not all ports
are equipped to handle ships of this
size, feeder ships (ships that carry
containers to ocean-going vessels in
smaller ports) have also increased in

size to carry as much as 2,000 TEUs.
Based on a rate of approximately $1,300
per TEU to ship a container from Asia
to the U.S., a net profit margin of 10%,
and an average of 16 trips per year, the
estimated cost due to displaced cargo to
call on a U.S./Canada ECA may be
$2,100.138 The cost139 analysis140
presented here does not include
displaced cargo due to the variability of
tank sizes owners choose to install.
To estimate the SCR hardware costs
associated with newly built ships, we
needed to generate an equation in terms
of $/kW that could be applied to other
engine sizes. Therefore, the $/kW values
representing the hardware costs
estimated for the six different engine
types and sizes used in this analysis was
developed using a curve fit for both SSD
and MSD engines. The resulting $/kW
values range from $40–$80 per kW for
MSD, and $40–70 for SSD. These costs
were then applied based on the
characteristics of the average ship types
described in the inventory section of the
draft RIA (see Chapter 3) to the
representative portion of the future fleet
in order to estimate the total costs
associated with this program. Table VII–
4 presents the estimated costs of this
technology as applied to different ship
and engine types representing the
average ship characteristics discussed in
Section VII.A.2.
(b) Lower Sulfur Fuel Hardware Costs
This cost analysis is based on the use
of switching to lower sulfur fuel to meet
the ECA fuel sulfur standards. The costs
presented here may be incurred by some
existing and some newly-built ships if
additional fuel tank equipment is
required to facilitate the use of lower
sulfur fuel. Based on existing vessel
fleet data, we estimate that
approximately one-third of existing
vessels may need additional equipment
installed to accommodate additional
lower sulfur fuel storage capacity
beyond that installed on comparable
new ships. In order to include any costs
that may be incurred on new vessels
that choose to add additional lower
sulfur fuel capacity, we also estimated
that one-third of new vessels may
require additional hardware. Separate $/
kW values were developed for new and
existing vessels as the existing vessel

140 Based on a container ship carrying nearly
9,000 TEUs traveling from Hong Kong to the Port
of Los Angeles (approximately 6,400 nm) with a
cruise speed of 25 nm/hr, the round trip time is
nearly 21 days and this trip could be made roughly
16 times per year.

retrofit would likely require more labor
to complete installation.
The size of the tank is dependent on
the frequency with which the individual
ship owner prefers to fill the lower
sulfur fuel tank. The size of the tanks
and corresponding $/kW value
estimated here will carry capacity
sufficient for 250 hours of propulsion
and auxiliary engine operation. This is
most likely an overestimate of the
amount of lower sulfur fuel a ship
owner would need to carry, resulting in
an overestimate of the total cost to
existing and new vessels. The tank sizes
based on 250 hours of operation and
based on the six different engine
configuration used in this analysis range
from 240 m3 to nearly 2,000 m3. This
would be the equivalent of 6–50 TEUs.
This cost analysis does not reflect other
design options such as partitioning of a
residual fuel tank to allow for lower
sulfur fuel capacity which would reduce
the amount of additional space required,
nor does this analysis reflect the
possibility that some ships may have
already been designed to carry smaller
amounts of distillate fuel in separate
tanks for purposes other than
continuous propulsion. The $/kW value
hardware cost values for the six data
points corresponding to the six different
engine types and sizes used in this
44493
analysis are $2–7 for SSD and $3–8 for
MSD. A curve fit was determined for the
slow-speed engine as well as for the
medium speed engines to determine a $/
kW value for each engine type. Table
VII–3 presents the estimated costs of the
technologies used to meet the different
standards as applied to different ship
and engine types representing the
average ship characteristics discussed in
Section VII.A.2. The estimated hardware
costs of retrofitting existing U.S.-flagged
vessels that may require additional
hardware to accommodate the use of
lower sulfur fuel is estimated to be
$10.4 million in 2015.

The total hardware costs associated
with the coordinated strategy were
estimated using the number of new
ships by ship type and engine type
entering the fleet each year. Table VII–

total costs from 2010 through 2040 are
estimated to be $42.9 billion at a 3
percent discount rate or $22.1 at a 7

C. Cost Effectiveness
One tool that can be used to assess the
value of the coordinated strategy is the
engineering costs incurred per ton of
emissions reduced. This analysis
involves a comparison of our proposed
program to other measures that have
been or could be implemented. As
summarized in this section, the
coordinated strategy represents a highly
cost effective mobile source control

program for reducing NOX, PM and SOX
emissions.
We have estimated the cost per ton
based on the net present value of 3
percent and 7 percent of all hardware
costs incurred by U.S.-flagged vessels,
all operational costs incurred by both
U.S. and foreign-flagged vessels, and all
emission reductions generated from the
year 2010 through the year 2040. The
baseline case for these estimated
U.S. flag

reductions is the existing set of engine
standards for C3 marine diesel engines
and fuel sulfur limits. Table VII–5
shows the annual emissions reductions
associated with the coordinated
strategy; these annual tons are
undiscounted. A description of the
methodology used to estimate these
annual reductions can be found in
Section II of this preamble and Chapter
3 of the draft RIA.

The net estimated reductions by
pollutant, using a net present value of
3 percent from 2010 through 2040 are
14.4 million tons of NOX, 19.1 million
tons of SOX, and 2.1 million tons of PM
(6.9 million, 10.1 million, and 1.1
million tons of NOX, SOX, and PM,
respectively, at a net present value of 7
percent over the same period.)
Using the above cost and emission
reduction estimates, we estimated the
lifetime (2010 through 2040) cost per
ton of pollutant reduced. For this
analysis, all of the hardware costs
associated with the Annex VI existing
engine program and Tier 2 and Tier 3
NOX standards as well as the
operational costs associated with the
global Tier II and Tier III standards were
attributed to NOX reductions. The costs
associated with lower sulfur fuel
operational costs as applied to all
vessels visiting U.S. ports and the
hardware costs associated with
accommodating the use of lower sulfur
fuel on U.S.-flagged vessels were
associated with SOX and PM reductions.
In this analysis, half of the costs
associated with the use of lower sulfur
fuel were allocated to PM reductions
and half to SOX reductions, because the
costs incurred to reduce SOX emissions
directly reduce emissions of PM as well.
Using this allocation of costs and the
PM
emission reductions shown in Table
VII–5, we can estimate the lifetime cost
per ton reduced associated with each
pollutant. These results are shown in
Table VII–6. Using a net present value
of 3 percent, the discounted lifetime
cost per ton of pollutant reduced is $510
for NOX, $930 for SOX, and $7,950 for
PM ($500, $920, and $7,850 per ton of
NOX, SOX, and PM, respectively, at a
net present value of 7 percent.) As
shown in Table VII–6, these estimated
discounted lifetime costs are similar to
the annual long-term (2030) cost per ton
of pollutant reduced.

These results for the coordinated
strategy compare favorably to other air
emissions control programs. Table VII–
7 compares the coordinated strategy to
other air programs. This comparison
shows that the coordinated strategy will
provide a cost-effective strategy for
generating substantial NOX, SOX, and
PM reductions from ocean-going
vessels. The results presented in Table
VII–7 are lifetime costs per ton
discounted at a net present value of 3
percent, with the exception of the
stationary source program and
locomotive/marine retrofits, for which
annualized costs are presented. While
results at a net present value of 7
percent are not presented, the results
142 The $/ton numbers presented here vary from
those presented in the ECA proposal due to the net
present value of the annualized reductions being
applied from 2015-2020, and the use of metric
tonnes rather than of short tons.

Notes:
A Table presents aggregate program-wide cost/ton over 30 years, discounted at a 3 percent NPV, except for Stationary CI Engines and Locomotive/Marine retrofits, for which annualized costs of control for individual sources are presented. All figures are in 2006 U.S. dollars per short
ton.
B Includes NO
X plus non-methane hydrocarbons (NMHC). NMHC are also ozone precursors, thus some rules set combined NOX + NMHC
emissions standards. NMHC are a small fraction of NOX so aggregate cost/ton comparisons are still reasonable.
C Low end of range represents costs for marine engines with credit for fuel savings, high end of range represents costs for other nonroad SI
engines without credit for fuel savings.
D. Economic Impact Analysis
This section contains our analysis of
the expected economic impacts of our
coordinated strategy on the markets for
Category 3 marine diesel engines, oceangoing vessels, and the U.S. marine
transportation service sector. We briefly
describe our methodology and present
our estimated expected economic
impacts.
As described below and in more
detail in the draft RIA, our economic
impact analysis uses a competitive
model approach for all affected markets.
We request comment on this approach,
or whether an alternative modeling
approach should be used for these
markets.
The total estimated social costs of the
coordinated strategy in 2030 are
equivalent to the estimated compliance
costs of the coordinated strategy, at
approximately $3.1 billion.143 These
costs are expected to accrue initially to
the owners and operators of affected
vessels. These owners and operators are
expected to pass their increased costs on
to the entities that purchase
international marine transportation
services, in the form of higher freight
rates. Ultimately, these costs will be
143 The costs totals reported in this NPRM are
slightly different than those reported in the ECA
proposal. This is because the ECA proposal did not
include costs associated with the Annex VI existing
engine program, Tier II, or the costs associated with
existing vessel modifications that may be required
to accommodate the use of lower sulfur fuel.
Further, the cost totals presented in the ECA
package included Canadian cost estimates.

borne by the final consumers of goods
transported by ocean-going vessels in
the form of slightly higher prices for
those goods.
We estimate that compliance with the
coordinated strategy would increase the
price of a new vessel by 0.5 to 2 percent.
The impact of the coordinated strategy,
including the ECA controls, on the price
of ocean marine transportation services
would vary, depending on the route and
the amount of time spent in the
proposed U.S. ECA. For example, we
estimate that the cost of operating a ship
in liner service between Singapore,
Seattle, and Los Angeles/Long Beach,
which includes about 1,700 nm of
operation in the proposed ECA, would
increase by about 3 percent. For a
container ship, this represents a price
increase of about $18 per container,
assuming the total increase in operating
costs is passed on to the purchaser of
the marine transportation services. This
would be about a 3 percent price
increase. The per passenger price of a
seven-day Alaska cruise operating
entirely within the ECA is expected to
increase by about $7 per day. For ships
that spend less time in the ECA, the
expected increase in total operating
costs, and therefore the impacts on
freight prices, would be smaller.
It should be noted that this economic
analysis holds all other aspects of the
market constant except for the elements
of the coordinated strategy. It does not
attempt to predict future market
equilibrium conditions, particularly
PO 00000
Frm 00056
Fmt 4701
Sfmt 4702
with respect to how excess capacity in
today’s market due to the current
economic downturn will be absorbed.
This approach is appropriate because
the goal of an economic impact analysis
is to explore the impacts of a specific
program; allowing changes in other
market conditions would confuse the
impacts due to the proposed regulatory
program.
The remainder of this section
provides detailed information on the
methodology we used to estimate these
economic impacts and the results of our
analysis.
(1) What Is the Purpose of an Economic
Impact Analysis?
In general, the purpose of an
Economic Impact Analysis (EIA) is to
provide information about the potential
economic consequences of a regulatory
action, such as the proposed
coordinated strategy to reduce
emissions from ocean-going vessels.
Such an analysis consists of estimating
the social costs of a regulatory program
and the distribution of these costs across
stakeholders.
In an economic impact analysis,
social costs are the value of the goods
and services lost by society resulting
from (a) the use of resources to comply
with and implement a regulation and (b)
reductions in output. There are two
parts to the analysis.
In the market analysis, we estimate
how prices and quantities of goods
directly affected by the emission control
program can be expected to change once

the program goes into effect. In the
economic welfare analysis, we look at
the total social costs associated with the
program and their distribution across
key stakeholders.
(2) How Did We Estimate the Economic
Impacts of the Coordinated Strategy?
Our analysis of the economic impacts
of the coordinated strategy is based on
the application of basic microeconomic
theory. We use a competitive market
model approach in which the
interaction between supply and demand
determines equilibrium market prices
and quantities. For markets in which
there are many producers, such as the
vessel building and transportation
services markets, this approach is
reasonable.144 For the Category 3 engine
market, the market structure and
therefore the choice of model is more
complicated. This market consists of a
small number of manufacturers (2
companies comprising about 60 percent
of the market, with two others having a
notable share), which suggests that an
oligopolistic modeling approach may be
more appropriate. In markets with a
small number of producers, it is not
uncommon for manufacturers to
exercise market power to obtain prices
above the competitive market clearing
price, thereby securing greater profits. In
such markets, market prices would
increase more than the compliance costs
of the regulatory program. However, an
oligopoly market structure does not
necessarily mean that the firms behave
non-competitively. According to the
Bertrand competition model, price
competition among even a few
manufacturers achieves socially optimal
results similar to a competitive
market.145 The Bertrand competition
model relies on price competition
between the firms; price competition
among the firms may be reduced when
the manufacturers face sharply rising
marginal costs, when they compete
repeatedly, or when their products are
differentiated. We request comment on
whether Category 3 engine
manufacturers behave competitively,
competing on price, or whether some
other modeling approach should be
used for this market.
In a competitive structure model, we
use the relationships between supply
and demand to simulate how markets
can be expected to respond to increases
in production costs that occur as a result
of the new emission control program.
144 Stopford describes these markets as
competitive. See Stopford, Martin. Maritime
Economics, 3rd Edition (Routledge, 2009),
Chapter 4.

Organization (1989). MIT Press. See pages 223–224.

We use the laws of supply and demand
to construct a model to estimate the
social costs of the program and identify
how those costs will be shared across
the markets and, thus, across
stakeholders. The relevant concepts are
summarized below and are presented in
greater detail in Chapter 7 of the draft
RIA.
Before the implementation of a
control program, a market is assumed to
be in equilibrium, with producers
producing the amount of a good that
consumers desire to purchase at the
market price. The implementation of a
control program results in an increase in
production costs by the amount of the
compliance costs. This generates a
‘‘shock’’ to the initial equilibrium
market conditions (a change in supply).
Producers of affected products will try
to pass some or all of the increased
production costs on to the consumers of
these goods through price increases,
without changing the quantity
produced. In response to the price
increases, consumers will decrease the
quantity they buy of the affected good
(a change in the quantity demanded).
This creates surplus production at the
new price. Producers will react to the
decrease in quantity demanded by
reducing the quantity they produce, and
they will be willing to sell the
remaining production at a lower price
that does not cover the full amount of
the compliance costs. Consumers will
then react to this new price. These
interactions continue until the surplus
is removed and a new market
equilibrium price and quantity
combination is achieved.
The amount of the compliance costs
that will be borne by stakeholders is
ultimately limited by the price
sensitivity of consumers and producers
in the relevant markets, represented by
the price elasticities of demand and
supply for each market. An ‘‘inelastic’’
price elasticity (less than one) means
that supply or demand is not very
responsive to price changes (a one
percent change in price leads to less
than one percent change in quantity).
An ‘‘elastic’’ price elasticity (more than
one) means that supply or demand is
sensitive to price changes (a one percent
change in price leads to more than one
percent change in quantity). A price
elasticity of one is unit elastic, meaning
there is a one-to-one correspondence
between a percent change in price and
percent change in quantity.
On the production side, price
elasticity of supply depends on the time
available to adjust production in
response to a change in price, how easy
it is to store goods, and the cost of
increasing (or decreasing) output. In this
PO 00000
Frm 00057
Fmt 4701
Sfmt 4702
44497
analysis, we assume the supply for
engines, vessels, and marine
transportation services is elastic: an
increase in the market price of an
engine, vessel or freight rates will lead
producers to want to produce more,
while a decrease will lead them to
produce less (this is the classic upwardsloping supply curve). It would be
difficult to estimate the slope of the
supply curve for each of these markets
given the global nature of the sector.
However, it is reasonable to assume that
the supply elasticity for the ocean
marine transportation services market is
likely to be greater than one. This is
because output can more easily be
adjusted due to a change in price. For
the same reason, the supply elasticity
for the new Category 3 engine market is
also likely to be greater than one,
especially since these engines are often
used in other land-based industries,
notably in power plants. The supply
elasticity for the vessel construction
market, on the other hand, may be less
than or equal to one depending on the
vessel type, since it may be harder to
adjust production and/or store output if
the price drops, or rapidly increase
production if the price increases.
Because of the nature of this industry,
it would not be possible to easily switch
production to other goods, or to stop or
start production of new vessels.
On the consumption side, we assume
that the demand for engines is a
function of the demand for vessels,
which is a function of the demand for
international shipping (demand for
engines and vessels is derived from the
demand for marine transportation
services). This makes intuitive sense:
Category 3 engine and ocean-going
vessel manufacturers would not be
expected to build an engine or vessel
unless there is a purchaser, and
purchasers will want a new vessel/
engine only if there is a need for one to
supply marine transportation services.
Deriving the price elasticity of demand
for the vessel and engine markets from
the international shipping market is an
important feature of this analysis
because it provides a link between the
product markets.
In this analysis, the price elasticity of
demand for marine transportation
services, and therefore for vessels and
Category 3 engines, is nearly perfectly
inelastic. This stems from the fact that
for most goods, there are no reasonable
alternative shipping modes. In most
cases, transportation by rail or truck is
not feasible, and transportation by
aircraft is too expensive. Approximately
90 percent of world trade by tonnage is
moved by ship, and ships provide the
most efficient method to transport these
E:\FR\FM\28AUP2.SGM
28AUP2
44498
Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
goods on a tonne-mile basis.146 Stopford
notes that ‘‘shippers need the cargo and,
until they have time to make alternative
arrangements, must ship it regardless of
cost * * * The fact that freight
generally accounts for only a small
portion of material costs reinforces this
argument.’’ 147 A nearly perfectly
inelastic price elasticity of demand for
marine transportation services means
that virtually all of the compliance costs
can be expected to be passed on to the
consumers of marine transportation
services, with no change in output for
engine producers, ship builders, or
owners and operators of ships engaged
in international trade.
The economic impacts of the
coordinated strategy presented in this
section rely on the estimated
engineering compliance costs described
in Sections VII.A (fuels) and VII.B
(engines) above. These costs include
hardware costs for new U.S. vessels to
comply with the Tier 2 and Tier 3
engine standards, and for existing U.S.
vessels to comply with the MARPOL
Annex VI requirements for existing
engines. There are also hardware costs
for fuel switching equipment on new
and existing U.S. vessels to comply with
the 1,000 ppm fuel sulfur limit; the cost
analysis assumes that 32 percent of all
vessels require fuel switching
equipment to be added (new vessels) or
retrofit (existing vessels). Also included
are expected increases in operating costs
for U.S. and foreign vessels operating in
the inventory modeling domain,
including the proposed ECA. These
increased operating costs include
changes in fuel consumption rates,
increases in fuel costs, and the use of
urea for engines equipped with SCR.148
(3) What Are the Estimated Market
Impacts of the Coordinated Strategy?
(a) What Are the Estimated Engine and
Vessel Market Impacts of the
Coordinated Strategy?
The estimated market impacts for
engines and vessels are based on the
variable costs associated with the engine
and vessel compliance programs; fixed
costs are not included in the market
analysis. This is appropriate because in
a competitive market the industry
supply curve is generally based on the
market’s marginal cost curve; fixed costs
do not influence production decisions at
the margin. Therefore, the market
analysis for a competitive market is
based on variable costs only.
The assumption of nearly perfectly
inelastic demand for marine
transportation services means that the
quantity of these services purchased is
not expected to change as a result of
costs of complying with the ECA
requirements. As a result, the demand
for vessels and engines would also not
change compared to the no-control
scenario, and the quantities produced
would remain the same.
The assumption of nearly perfectly
inelastic demand for marine
transportation services also means the
price impacts of the coordinated
strategy on new engines and vessels
would be equivalent to the variable
engineering compliance costs. Estimated
price impacts for a sample of enginevessel combinations are set out in Table
VII–8 for medium speed engines, and
Table VII–9 for slow speed engines.
These are the estimated price impacts
associated with the Tier 3 engine
standards on a vessel that will switch
fuels to comply with the fuel sulfur
requirements in the ECA. Because the
standards do not phase in, the estimated
price impacts are the same for all years,
beginning in 2016.

Notes:
a The new vessel engine price impacts listed here do not include a per engine cost of $10,000 for engines installed on U.S. vessels to comply
with the proposed production testing requirement (§ 1042.302)
b Slow speed engine price impacts are estimated from the cost information presented in Chapter 5 using the following formula: (5%*($/
SHIP_MECH→CR))+(15%*($/SHIP_ELEC→CR))+(T3 ENGINE MODS)+(T3 SCR))
c Assumes 32 percent of new vessels would require the fuel switching equipment.
The estimated price impacts for Tier
2 vessels would be substantially lower,
given the technology that will be used
to meet the Tier 2 standards is much
less expensive. The cost of complying
with the Tier 2 standards ranges from
about $56,000 to $100,000 for a medium
speed engine, and from about $130,000
to $250,000 for a slow speed engine.
Again, because the standards do not
phase in, the estimated price impacts
are the same for all years the Tier 2
standards are required, 2011 through
2015.
These estimated price impacts for Tier
2 and Tier 3 vessels are small when
compared to the price of a new vessel.
A selection of new vessel prices is
provided in Table VII–10; these range
from about $40 million to $480 million.
The program price increases range from
about $600,000 to $1.5 million. A price
increase of $600,000 to comply with the
Tier 3 standards and fuel switching
requirements would be an increase of
approximately 2 percent for a $40
million vessel. The largest vessel price
increase noted above for a Tier 3
passenger vessel is about $1.5 million;
this is a price increase of less than 1
percent for a $478 million passenger
vessel. Independent of the nearlyperfect inelasticity of demand, price
increases of this magnitude would be
expected to have little, if any, effect on
the sales of new vessels, all other
economic conditions held constant.

(b) What Are the Estimated Fuel Market
Impacts of the Coordinated Strategy?
The market impacts for the fuel
markets were estimated through the
modeling performed to estimate the fuel
compliance costs for the coordinated
strategy. In the WORLD model, the total
quantity of fuel used is held constant,
which is consistent with the assumption
that the demand for international
shipping transportation would not be
expected to change due to the lack of
transportation alternatives.
The expected price impacts of the
coordinated strategy are set out in Table
VII–11. Note that on a mass basis, less
distillate than residual fuel is needed to
go the same distance (5 percent less).
The prices in Table VII–11 are adjusted
for this impact.
Table VII–11 shows that the
coordinated strategy is expected to
result in a small increase in the price of
marine distillate fuel, about 1.3 percent.
The price of residual fuel is expected to
decrease slightly, by less than one
percent, due to a reduction in demand
for that fuel.

Because of the need to shift from
residual fuel to distillate fuel in the
ECA, ship owners are expected to see an
increase in their total cost of fuel. This
increase is because distillate fuel is
more expensive than residual fuel.
Factoring in the higher energy content
of distillate fuel relative to residual fuel,
the fuel cost increase would be about 39
percent.

(c) What Are the Estimated Marine
Transportation Market Impacts of the
Coordinated Strategy?
We used the above information to
estimate the impacts on the prices of
marine transportation services. This
analysis, which is presented in Chapter
7 of the draft RIA, is limited to the
impacts of increases in operating costs

strategy. Operating costs would increase
due to the increase in the price of fuel,
the need to switch to fuel with a sulfur
content not to exceed 1,000 ppm while
operating in the ECA, and due to the
need to dose the aftertreatment system
with urea to meet the Tier 3 standards.
Table VII–12 summarizes these price
impacts for selected transportation
markets. Table VII–12 also lists the
vessel and engine parameters that were
used in the calculations.

This information suggests that the
increase in marine transportation
service prices would be small, both
absolutely and when compared to the
price charged by the ship owner per
unit transported. For example, Stopford
notes that the price of transporting a 20
foot container between the UK and
Canada is estimated to be about $1,500;
of that, $700 is the cost of the ocean
freight; the rest is for port, terminal, and
other charges.149 An increase of about
$18 represents an increase of less than
3 percent of ocean freight cost, and
about one percent of transportation cost.
Similarly, the price of a 7-day Alaska
cruise varies from $100 to $400 per
night or more. In that case, this price
increase would range from 1.5 percent
to about 6 percent.

(4) What Are the Estimated Social Costs
of the Coordinated Strategy and How
Are They Expected To Be Distributed
Across Stakeholders?
The total social costs of the
coordinated strategy are based on both
fixed and variable costs. This is because
fixed costs are a cost to society: they
displace other product development
activities that may improve the quality
or performance of engines and vessels.
In this economic impact analysis, fixed
costs are accounted for in the year in
which they occur, with the fixed costs
associated with the Tier 2 engine
standards accounted for in 2010 and the
fixed costs associated with the Tier 3
engine standards and the ECA controls
accounted for in the five-year period
beginning prior to their effective dates.
The social costs of the coordinated
strategy are estimated to be the same as
the total engineering compliance costs.
These costs for all years are presented
in Table VII–4. For 2030, the social costs

Fmt 4701
Sfmt 4702
Operational price increases
$17.53/TEU.
$0.56/tonne.
$6.60/per passenger per day
are estimated to be about $3.1 billion.150
For the reasons described above and
explained more fully in the draft RIA,
these costs are expected to be borne
fully by consumers of marine
transportation services.
These social costs are small when
compared to the total value of U.S.
waterborne foreign trade. In 2007,
waterborne trade for government and
non-government shipments by vessel
into and out of U.S. foreign trade zones,
the 50 states, the District of Columbia,
and Puerto Rico was about $1.4 trillion.
Of that, about $1 trillion was for
imports.151
150 The costs totals reported in this NPRM are
slightly different than those reported in the ECA
proposal. This is because the ECA proposal did not
include costs associated with the Annex VI existing
engine program, Tier II, or the costs associated with
existing vessel modifications that may be required
to accommodate the use of lower sulfur fuel.
Further, the cost totals presented in the ECA
package included Canadian cost estimates.

If only U.S. vessels are considered,
the social costs of the coordinated
strategy in 2030 would be about $427.5
million. Again, these social costs are
small when compared to the annual
revenue for this sector. In 2002, the
annual revenue for this sector was about
$19.8 billion.152
(5) Alternative Analysis
The above analysis is based on the
assumption of near-perfectly inelastic
demand for ocean marine transportation
services. In this section, we discuss the
implications of relaxing this assumption
to consider the impacts of the
coordinated strategy if consumers of
marine transportation services were able
to react to an increase in prices by
reducing their demand for these
services.
The marine transportation services
market is a global market, which makes
it complicated to estimate the price
sensitivity of demand. In addition, that
sensitivity would likely vary depending
on the types of goods transported and
the type of vessel used. For example, the
demand elasticity for bulk cargo
transportation services would likely
vary depending on the type of bulk (e.g.,
food, oil, electronic goods) and the type
of vessel (bulk/tramp or liner). Instead
of estimating these price elasticities, this
alternative analysis relies on the price
elasticities we developed for our 2008
rulemaking that set technology-forcing
standards for Category 1 and Category 2
engines (73 FR 25098, May 6, 2008).
Although these price elasticities of
demand and supply were developed
using data for United States markets
only, they reflect behavioral reactions to
price changes if alternative modes of
transportation were available. The
values used for the behavioral
parameters for the Category 1 and 2
markets are provided in Table VII–13.

Notes:
a Commercial vessels include tug/tow/pushboats, ferries, cargo vessels, crew/supply boats, and other commercial vessels.
The alternative price elasticity of
demand for marine transportation
services is inelastic, at ¥0.5. This
means a one percent increase in price
will result in a 0.5 percent decrease in
demand. This inelastic demand
elasticity will yield inelastic demand
elasticities for both engines and vessels.
The estimates of the price elasticity of
supply are elastic, consistent with the
primary analysis described above.
Rather than create a computer model
to estimate the economic impacts of the
coordinated strategy using this revised
set of assumptions, we examine their
impact qualitatively. In general, relaxing
the condition of nearly perfectly
inelastic demand elasticity would result
in the compliance costs of the
coordinated strategy being shared by
consumers and suppliers. In the engine
and vessel markets, the share borne by
producers would nevertheless be
expected to be small, given the elastic
supply elasticity compared to the
inelastic demand elasticity. Because
suppliers would bear part of the
compliance costs, the price increase for
engines and vessels would be smaller
than the per-unit engineering
compliance costs. In the marine
transportation market, the price impacts
would be shared more equally between
producers (vessel owners) and
consumers (firms that purchase marine
transportation services), due to the
nearly identical price elasticity of
supply (0.6) and demand (¥0.5).
However, given the relatively small per
unit engineering costs, the total impacts
on prices and quantities in these
markets would still be expected to be
modest.
In addition, there would be a small
change in demand since consumers
would react to an increase in price by
reducing their consumption of marine
transportation services. Again, because
the relative price impact is small, the
impact on quantity would also be small.
The distribution of compliance costs
from our earlier rule are presented in
Table VII–14. While the emission
control requirements and the
compliance cost structure of the
coordinated strategy are somewhat
different, these results give an idea of
how costs would be shared if the
assumption of nearly perfectly inelastic
price elasticity of demand for the
transportation services market in the
ocean-going marine sector were relaxed.

VIII. Benefits
This section presents our analysis of
the health and environmental benefits
that are estimated to occur as a result of
EPA’s coordinated strategy to address
emissions from Category 3 engines and
ocean-going vessels throughout the
period from initial implementation
through 2030. We provide estimated
benefits for the entire coordinated
strategy, including the Annex VI Tier 2
NOX requirements and the ECA controls
that will be mandatory for U.S. and
foreign vessels through the Act to
Prevent Pollution from Ships. However,
unlike the cost analysis, this benefits
analysis does not allocate benefits
between the components of the program
(the requirements in this rule and the
requirements that would apply through
MARPOL Annex VI and ECA
implementation). This is because the
benefits of the coordinated strategy will
be fully realized only when the U.S.
ECA is in place and both U.S. and
foreign vessel are required to use lower
sulfur fuel and operate their Tier 3 NOX
controls while in the designated area,
and therefore it makes more sense to
consider the benefits of the coordinated
strategy as a whole.
The components of the coordinated
strategy would apply stringent NOX and
SOX standards to virtually all vessels
that affect U.S. air quality, and impacts
on human health and welfare would be
substantial. As presented in Section II,
the coordinated is expected to provide
very large reductions in direct PM, NOX,
SOX, and toxic compounds, both in the
near term and in the long term.
Emissions of NOX (a precursor to ozone
formation and secondarily-formed
PM2.5), SOX (a precursor to secondarilyformed PM2.5) and directly-emitted
PM2.5 contribute to ambient
concentrations of PM2.5 and ozone.
Exposure to ozone and PM2.5 is linked
to adverse human health impacts such
as premature deaths as well as other
important public health and
environmental effects.
Using the most conservative
premature mortality estimates (Pope et
al., 2002 for PM2.5 and Bell et al., 2004
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
for ozone),153, 154 we estimate that
implementation of the coordinated
strategy would reduce approximately
13,000 premature mortalities in 2030
and yield approximately $110 billion in
total benefits. The upper end of the
premature mortality estimates (Laden et
al., 2006 for PM2.5 and Levy et al., 2005
for ozone) 155, 156 increases avoided
premature mortalities to approximately
32,000 in 2030 and yields
approximately $280 billion in total
benefits. Thus, even taking the most
conservative premature mortality
assumptions, the health impacts of the
coordinated strategy presented in this
proposal are clearly substantial.
A. Overview
We base our analysis on peerreviewed studies of air quality and
human health effects (see U.S. EPA,
2006 and U.S. EPA,
2008).157, thnsp;158 These methods are
described in more detail in the draft RIA
that accompanies this proposal. To
model the ozone and PM air quality
impacts of the proposed CAA standards
and requirements and the ECA
designation, we used the Community

(see Section II). The modeled ambient
air quality data serves as an input to the
Environmental Benefits Mapping and
Analysis Program (BenMAP).159
BenMAP is a computer program
developed by the U.S. EPA that
integrates a number of the modeling
elements used in previous analyses (e.g.,
interpolation functions, population
projections, health impact functions,
valuation functions, analysis and
pooling methods) to translate modeled
air concentration estimates into health
effects incidence estimates and
monetized benefits estimates.
The range of total ozone- and PMrelated benefits associated with the
coordinated strategy to control ship
emissions is presented in Table VIII–1.
We present total benefits based on the
PM- and ozone-related premature
mortality function used. The benefits
ranges therefore reflect the addition of
each estimate of ozone-related
premature mortality (each with its own
row in Table VIII–1) to estimates of PMrelated premature mortality. These
estimates represent EPA’s preferred
approach to characterizing the best
estimate of benefits associated with the
coordinated strategy. As is the nature of
Regulatory Impact Analyses (RIAs), the
assumptions and methods used to
estimate air quality benefits evolve to
reflect the Agency’s most current
interpretation of the scientific and
economic literature. This analysis,
therefore, incorporates four important
changes from recent RIAs released by
the Office of Transportation and Air
Quality (OTAQ):
• As is the nature of Regulatory
Impact Analyses (RIAs), the
assumptions and methods used to
estimate air quality benefits evolve over
time to reflect the Agency’s most current
interpretation of the scientific and
economic literature. For a period of time
(2004–2008), the Office of Air and
Radiation (OAR) valued mortality risk
reductions using a value of statistical
life (VSL) estimate derived from a
limited analysis of some of the available
studies. OAR arrived at a VSL using a
157 U.S. Environmental Protection Agency. (2006).

range of $1 million to $10 million
(2000$) consistent with two metaanalyses of the wage-risk literature. The
$1 million value represented the lower
end of the interquartile range from the
Mrozek and Taylor (2002) 160 metaanalysis of 33 studies and $10 million
represented the upper end of the
interquartile range from the Viscusi and
Aldy (2003) 161 meta-analysis of 46

million (2000$) 162 was also consistent
with the mean VSL of $5.4 million
estimated in the Kochi et al. (2006) 163
meta-analysis. However, the Agency
neither changed its official guidance on
the use of VSL in rule-makings nor
subjected the interim estimate to a
scientific peer-review process through
the Science Advisory Board (SAB) or
other peer-review group.
During this time, the Agency
continued work to update its guidance
on valuing mortality risk reductions,
including commissioning a report from
meta-analytic experts to evaluate
methodological questions raised by EPA
and the SAB on combining estimates
from the various data sources. In
addition, the Agency consulted several
times with the Science Advisory Board
Environmental Economics Advisory
Committee (SAB–EEAC) on the issue.
With input from the meta-analytic
experts, the SAB–EEAC advised the
Agency to update its guidance using
specific, appropriate meta-analytic
techniques to combine estimates from
unique data sources and different
studies, including those using different
methodologies (i.e., wage-risk and stated
preference) (U.S. EPA–SAB, 2007).164
Until updated guidance is available,
the Agency determined that a single,
peer-reviewed estimate applied
consistently best reflects the SAB–EEAC
advice it has received. Therefore, the
Agency has decided to apply the VSL
that was vetted and endorsed by the
SAB in the Guidelines for Preparing
158 U.S. Environmental Protection Agency. (2008).

• In recent analyses, OTAQ has
estimated PM2.5-related benefits
assuming that a threshold exists in the
PM-related concentration-response
functions (at 10 μg/m3) below which
there are no associations between
exposure to PM2.5 and health impacts.
EPA strives to use the best available
science to support our benefits analyses,
and we recognize that interpretation of
the science regarding air pollution and
health is dynamic and evolving. Based
on our review of the body of scientific
literature, EPA applied the no-threshold
model in this analysis. Removing the
threshold assumption is consistent with
the approach taken in the recently
published Portland Cement MACT

concentration-response relationship
while recognizing potential uncertainty
about the exact shape of the
concentration-response function.
Although this document does not
represent final agency policy that has
undergone the full agency scientific
review process, it provides a basis for
reconsidering the application of
thresholds in PM2.5 concentrationresponse functions used in EPA’s RIAs.
It is important to note that while
CASAC provides advice regarding the
science associated with setting the
National Ambient Air Quality
Standards, typically other scientific
advisory bodies provide specific advice
regarding benefits analysis. Because the
Portland Cement RIA was completed
while CASAC was reviewing the PM
ISA, we solicited comment on the use
of the no-threshold model for benefits
analysis within the preamble of that
proposed rule. The comment period for
the Portland Cement proposed NESHAP
has been extended until September 4,
2009.170 Please see Section 6.4.1.3 of the
RIA that accompanies this preamble for
more discussion of the treatment of
thresholds in this analysis.
• For the coordinated strategy, we
rely on two empirical (epidemiological)
studies of the relationship between
ambient PM2.5 and premature mortality
(the extended analyses of the Harvard
Six Cities study by Laden et al (2006)
and the American Cancer Society (ACS)
cohort by Pope et al (2002)) to anchor
our benefits analysis, though we also
present the PM2.5-related premature
mortality benefits associated with the
estimates supplied by the expert
elicitation as a sensitivity analysis. This
approach was recently adopted in the
Portland Cement MACT RIA. Since
2006, EPA has calculated benefits based
on these two empirical studies and
derived the range of benefits, including
the minimum and maximum results,

relationship between exposure to PM2.5
and premature mortality (Roman et al.,
2008).171 Using alternate relationships
between PM2.5 and premature mortality
supplied by experts, higher and lower
benefits estimates are plausible, but
most of the expert-based estimates have
fallen between the two epidemiologybased estimates (Roman et al., 2008).
Assuming no threshold in the
empirically-derived premature mortality
concentration response functions used
in the analysis of the coordinated
strategy, only one expert falls below the
empirically-derived range while two of
the experts are above this range (see
Tables 6–5 and 6–6 in the draft RIA that
accompanies this preamble). Please refer
to the Portland Cement MACT RIA for
more information about the preferred
approach and the evolution of the
treatment of threshold assumptions
within EPA’s regulatory analyses.
• The range of ozone benefits
associated with the coordinated strategy
is estimated based on risk reductions
derived from several sources of ozonerelated mortality effect estimates. This
analysis presents six alternative
estimates for the association based upon
different functions reported in the
scientific literature. We use three multicity studies,172, 173, 174 including the Bell,
2004 National Morbidity, Mortality, and
Air Pollution Study (NMMAPS) that
was used as the primary basis for the
risk analysis in the ozone Staff Paper175
and reviewed by the Clean Air Science
Advisory Committee (CASAC).176 We
also use three studies that synthesize
ozone mortality data across a large
number of individual studies.177, 178, 179
This approach is consistent with
recommendations provided by the NRC
in their ozone mortality report (NRC,
2008),180 ‘‘The committee recommends
that the greatest emphasis be placed on
estimates from new systematic multicity
analyses that use national databases of
air pollution and mortality, such as in
the NMMAPS, without excluding
consideration of meta-analyses of
previously published studies.’’ The NRC
goes on to note that there are
uncertainties within each study that are
not fully captured by this range of
estimates.

The benefits in Table VIII–1 include
all of the human health impacts we are
able to quantify and monetize at this
time. However, the full complement of
human health and welfare effects
associated with PM and ozone remain
unquantified because of current
limitations in methods or available data.
We have not quantified a number of
known or suspected health effects
linked with ozone and PM for which
appropriate health impact functions are
not available or which do not provide
easily interpretable outcomes (i.e.,
changes in heart rate variability).
Additionally, we are unable to quantify
a number of known welfare effects,
including reduced acid and particulate
deposition damage to cultural
monuments and other materials, and
environmental benefits due to
reductions of impacts of eutrophication
in coastal areas. These are listed in
Table VIII–2. As a result, the health
benefits quantified in this section are
likely underestimates of the total
benefits attributable to the

Notes:
a The public health impact of biological responses such as increased airway responsiveness to stimuli, inflammation in the lung, acute inflammation and respiratory cell damage, and increased susceptibility to respiratory infection are likely partially represented by our quantified
endpoints.
b The public health impact of effects such as chronic respiratory damage and premature aging of the lungs may be partially represented by
quantified endpoints such as hospital admissions or premature mortality, but a number of other related health impacts, such as doctor visits and
decreased athletic performance, remain unquantified.
c In addition to primary economic endpoints, there are a number of biological responses that have been associated with PM health effects including morphological changes and altered host defense mechanisms. The public health impact of these biological responses may be partly represented by our quantified endpoints.
d While some of the effects of short-term exposures are likely to be captured in the estimates, there may be premature mortality due to shortterm exposure to PM not captured in the cohort studies used in this analysis. However, the PM mortality results derived from the expert
elicitation do take into account premature mortality effects of short term exposures.

B. Quantified Human Health Impacts
Tables VIII–3 and VIII–4 present the
annual PM2.5 and ozone health impacts
in the 48 contiguous U.S. states
associated with the coordinated strategy
for both 2020 and 2030. For each
endpoint presented in Tables VIII–3 and
VIII–4, we provide both the mean
estimate and the 90% confidence
interval.
Using EPA’s preferred estimates,
based on the ACS and Six-Cities studies
and no threshold assumption in the
model of mortality, we estimate that the
coordinated strategy would result in
between 5,300 and 14,000 cases of
avoided PM2.5-related premature deaths
annually in 2020 and between 13,000
and 32,000 avoided premature deaths
annually in 2030. As a sensitivity
analysis, when the range of expert
opinion is used, we estimate between
1,900 and 18,000 fewer premature
mortalities in 2020 and between 4,500
and 42,000 fewer premature mortalities
in 2030 (see Tables 6–5 and 6–6 in the
draft RIA that accompanies this
proposal).
For ozone-related premature
mortality, we estimate a range of
between 61 to 280 fewer premature
mortalities as a result of the coordinated
strategy in 2020 and between 220 to 980
in 2030. The increase in annual benefits
from 2020 to 2030 reflects additional
emission reductions from coordinated
strategy, as well as increases in total
population and the average age (and
thus baseline mortality risk) of the
population.

C. Monetized Benefits
Table VIII–5 presents the estimated
monetary value of reductions in the
incidence of ozone and PM2.5-related
health effects. All monetized estimates
are stated in 2006$. These estimates
account for growth in real gross
domestic product (GDP) per capita
between the present and the years 2020
and 2030. As the tables indicate, total
benefits are driven primarily by the
reduction in premature fatalities each
year.

Jkt 217001
Our estimate of total monetized
benefits in 2020 for the coordinated
strategy, using the ACS and Six-Cities
PM mortality studies and the range of
ozone mortality assumptions, is
between $47 billion and $110 billion,
assuming a 3 percent discount rate, or
between $42 billion and $100 billion,
assuming a 7 percent discount rate. In
2030, we estimate the monetized
benefits to be between $110 billion and
$280 billion, assuming a 3 percent
discount rate, or between $100 billion

and $260 billion, assuming a 7 percent
discount rate. The monetized benefit
associated with reductions in the risk of
both ozone- and PM2.5-related
premature mortality ranges between 90
to 98 percent of total monetized health
benefits, in part because we are unable
to quantify a number of benefits
categories (see Table VIII–2). These
unquantified benefits may be
substantial, although their magnitude is
highly uncertain.

• Uncertainties in the estimation of
future year emissions inventories and
air quality;
• Uncertainty in the estimated
relationships of health and welfare
effects to changes in pollutant
concentrations including the shape of
the C–R function, the size of the effect
estimates, and the relative toxicity of the
many components of the PM mixture;
• Uncertainties in exposure
estimation; and
• Uncertainties associated with the
effect of potential future actions to limit
emissions.
As Table VIII–5 indicates, total
benefits are driven primarily by the
reduction in premature mortalities each
year. Some key assumptions underlying
the premature mortality estimates
include the following, which may also
contribute to uncertainty:
• Inhalation of fine particles is
causally associated with premature
death at concentrations near those
experienced by most Americans on a
daily basis. Although biological
mechanisms for this effect have not yet
been completely established, the weight
of the available epidemiological,
toxicological, and experimental
evidence supports an assumption of
causality. The impacts of including a
probabilistic representation of causality
were explored in the expert elicitationbased results of the PM NAAQS RIA.
• All fine particles, regardless of their
chemical composition, are equally
potent in causing premature mortality.

D. What Are the Limitations of the
Benefits Analysis?
Every benefit-cost analysis examining
the potential effects of a change in
environmental protection requirements
is limited to some extent by data gaps,
limitations in model capabilities (such
as geographic coverage), and
uncertainties in the underlying
scientific and economic studies used to
configure the benefit and cost models.
Limitations of the scientific literature
often result in the inability to estimate
quantitative changes in health and
environmental effects, such as potential
increases in premature mortality
associated with increased exposure to
carbon monoxide. Deficiencies in the
economics literature often result in the
inability to assign economic values even
to those health and environmental
outcomes which can be quantified.
These general uncertainties in the
underlying scientific and economics
literature, which can lead to valuations
that are higher or lower, are discussed
in detail in the draft RIA and its
supporting references. Key uncertainties
that have a bearing on the results of the
benefit-cost analysis of the coordinated
strategy include the following:
• The exclusion of potentially
significant and unquantified benefit
categories (such as health, odor, and
ecological benefits of reduction in air
toxics, ozone, and PM);
• Errors in measurement and
projection for variables such as
population growth;

Sfmt 4702
This is an important assumption,
because PM produced via transported
precursors emitted from marine engines
may differ significantly from PM
precursors released from electric
generating units and other industrial
sources. However, no clear scientific
grounds exist for supporting differential
effects estimates by particle type.
• The C–R function for fine particles
is approximately linear within the range
of ambient concentrations under
consideration. Thus, the estimates
include health benefits from reducing
fine particles in areas with varied
concentrations of PM, including both
regions that may be in attainment with
PM2.5 standards and those that are at
risk of not meeting the standards.
• There is uncertainty in the
magnitude of the association between
ozone and premature mortality. The
range of ozone benefits associated with
the proposed strategy is estimated based
on the risk of several sources of ozonerelated mortality effect estimates. In a
recent report on the estimation of ozonerelated premature mortality published
by the National Research Council, a
panel of experts and reviewers
concluded that short-term exposure to
ambient ozone is likely to contribute to
premature deaths and that ozone-related
mortality should be included in
estimates of the health benefits of
reducing ozone exposure.182 EPA has

Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
requested advice from the National
Academy of Sciences on how best to
quantify uncertainty in the relationship
between ozone exposure and premature
mortality in the context of quantifying
benefits.
Emissions and air quality modeling
decisions are made early in the
analytical process. For this reason, the
emission control scenarios used in the
air quality and benefits modeling are
slightly different than the coordinated
strategy. The discrepancies impact the
benefits analysis in three ways:
• The air quality modeling used for
the 2020 scenarios is based on inventory
estimates that were modeled using
incorrect boundary information. We
believe the impact of this difference,
while modest, likely leads to a small
underestimate of the benefits that are
presented in this section. Please refer to
the Chapter 3 of the draft RIA for more
information on the emissions excluded
from the health impacts analysis.
• The 2020 air quality modeling
scenarios do not include emission
reductions associated with the
implementation of global controls (set
through IMO) beyond the assumed ECA
boundary of 200 nautical miles (nm).
Again, while we expect the impact of
this difference is modest, the omission
of these additional emission reductions
likely leads to a small underestimate of
the 2020 benefits presented in this
section.
• As described in Section II, the air
quality modeling for the 2030 scenario
reflects air quality impacts associated
with an assumed ECA distance of 100
nm with global controls (set through
IMO) beyond the ECA boundary. To
estimate the 2030 benefits associated
with a 200 nm ECA boundary, we
transferred the relationship between
modeled impacts between 100 nm and
200 nm ECA boundaries observed in
2020. For each health endpoint and
associated valuation, we calculated a
ratio based on the national-level
estimate for the 200 nm and 100 nm
scenario and applied that to the related
2030 100 nm estimate. For the final
rulemaking, we plan to model the 2030
coordinated strategy to control ship
emissions with a 200 nm boundary and
global controls beyond.
Despite the uncertainties described
above, we believe this analysis provides
a conservative estimate of the estimated
economic benefits of the standards in
future years because of the exclusion of
potentially significant benefit categories
that are not quantifiable at this time.
Acknowledging benefits omissions and
uncertainties, we present a best estimate
of the total benefits based on our
interpretation of the best available
scientific literature and methods
supported by EPA’s technical peer
review panel, the Science Advisory
Board’s Health Effects Subcommittee
(SAB–HES). The National Academies of
Science (NRC, 2002) has also reviewed
EPA’s methodology for analyzing the
health benefits of measures taken to
reduce air pollution. EPA addressed
many of these comments in the analysis
of the final PM NAAQS.183 184 This
analysis incorporates this most recent
work to the extent possible.
E. Comparison of Costs and Benefits
This section presents the cost-benefit
comparison related to the expected
impacts of our coordinated strategy for
ocean-going vessels. In estimating the
net benefits of the coordinated strategy,
the appropriate cost measure is ‘social
costs.’ Social costs represent the welfare
costs of a rule to society and do not
consider transfer payments (such as
taxes) that are simply redistributions of
wealth. For this analysis, we estimate
that the social costs of the coordinated
program are equivalent to the estimated
compliance costs of the program. While
vessel owners and operators will see
their costs increase by the amount of
those compliance costs, they are
expected to pass them on in their
entirety to consumers of marine
transportation services in the form of
increased freight rates. Ultimately, these
costs will be borne by the final
consumers of goods transported by
ocean-going vessels in the form of
higher prices for those goods. The social
benefits of the coordinated strategy are
represented by the monetized value of
health and welfare improvements
experienced by the U.S. population.
Table VIII–6 contains the estimated
social costs and the estimated
monetized benefits of the coordinated
strategy.
The results in Table VIII–6 suggest
that the 2020 monetized benefits of the
coordinated strategy are greater than the
expected costs. Specifically, the annual
benefits of the total program will range
between $47 to $110 billion annually in
2020 using a three percent discount rate,
or between $42 to $100 billion assuming
a 7 percent discount rate, compared to
estimated social costs of approximately
$1.9 billion in that same year. These
benefits are expected to increase to
between $110 and $280 billion annually
in 2030 using a three percent discount
rate, or between $100 and $260 billion
assuming a 7 percent discount rate,
while the social costs are estimated to
be approximately $3.1 billion. Though
there are a number of health and
environmental effects associated with
the coordinated strategy that we are
unable to quantify or monetize (see
Table VIII–2), the benefits of the
coordinated strategy far outweigh the
projected costs.
Using a conservative benefits
estimate, the 2020 benefits outweigh the
costs by a factor of 22. Using the upper
end of the benefits range, the benefits
could outweigh the costs by a factor of
58. Likewise, in 2030 benefits outweigh
the costs by at least a factor of 32 and
could be as much as a factor of 90. Thus,
even taking the most conservative
benefits assumptions, benefits of the
coordinated strategy clearly outweigh
the costs.

Notes:
a All estimates represent annual benefits and costs anticipated for the years 2020 and 2030. Totals are rounded to two significant digits and
may not sum due to rounding.
b The calculation of annual costs does not require amortization of costs over time. Therefore, the estimates of annual cost do not include a discount rate or rate of return assumption (see Chapter 7 of the draft RIA). In Chapter 7, however, we use both a 3 percent and 7 percent social
discount rate to calculate the net present value of total social costs consistent with EPA and OMB guidelines for preparing economic analyses.
c Total includes ozone and PM
2.5 benefits. Range was developed by adding the estimate from the Bell et al., 2005 ozone premature mortality
function to PM2.5-related premature mortality derived from the ACS (Pope et al., 2002) and Six-Cities (Laden et al., 2006) studies.
d Annual benefits analysis results reflect the use of a 3 percent and 7 percent discount rate in the valuation of premature mortality and nonfatal
myocardial infarctions, consistent with EPA and OMB guidelines for preparing economic analyses.
e Valuation of premature mortality based on long-term PM exposure assumes discounting over the SAB recommended 20-year segmented lag
structure described in the Regulatory Impact Analysis for the Final Clean Air Interstate Rule (March, 2005).
f Not all possible benefits or disbenefits are quantified and monetized in this analysis. Potential benefit categories that have not been quantified
and monetized are listed in Table VIII–2.
IX. Alternative Program Options
EPA’s coordinated strategy to control
emissions from ocean-going vessels
consists of a number of components
including Clean Air Act standards for
Category 3 engines and designation of
an ECA for U.S. coasts through
amendment to MARPOL Annex VI. The
coordinated strategy will ensure that all
ships operating within 200 nautical
miles of U.S. coasts meet the most
stringent NOX standards and fuel sulfur
limits by 2015 (fuel sulfur) and 2016
(engine NOX).
The air quality and benefits analysis
we performed for the coordinated
strategy suggests that substantial human
health and environmental benefits can
be obtained from additional reductions
in emissions from ocean-going vessels,
and many stakeholders have expressed
a desire for additional NOX reductions
from OGV in earlier years, prior to the
effective dates for the Tier 2 and Tier 3
NOX limits. As described in Section I,
above, EPA has a number of port
initiatives under our National Clean
Diesel Campaign to reduce emissions
from this sector. These include
recognition for efforts by port
authorities and their customers to
reduce emissions from OGV through a
variety of efforts, grants under the
Energy Policy Act of 2005 Diesel
Emissions Reduction Program to
electrify piers and repower C1 and C2
marine vessels, and grants under the
Clean Air Act to demonstrate sea water
scrubbers and to provide incentives to
ship operators to use lower sulfur
fuels.185 EPA has also sponsored a
number of workshops and conferences
focused on exchanging technical
information about emissions reduction
techniques for ships (Clean Ships

Conference in San Diego in 2007, Faster
Freight meetings on East and West
coasts, and up-coming workshop with
MARAD). EPA welcomes comment on
ways in which the NCDC can be
improved through ideas such as
incentives (including financing
schemes) to facilitate faster introduction
of cleaner fuels and engine technologies,
eco-speed programs, and adoption of
other emission reduction methods that
can be used on a vessel-specific or portspecific basis.
In addition, we evaluated several
programmatic alternatives including
mandating the use of shoreside power in
our CAA program, pulling the effective
date of the CAA Tier 3 standards ahead,
and various options for addressing
emissions from existing engines. We
also considered action under the Clean
Air Act to apply the Tier 3 standards to
foreign vessels that operate in the
United States. However, as explained in
more detail in Section V.D, foreign
vessels will be required to comply with
the Annex VI NOX and fuel sulfur limits
through U.S. ECA designation and
therefore it is unnecessary to take action
under the Act at this time.
The remainder of this section presents
a summary of our analysis of these
alternative control scenarios. We are
interested in comments on each of these
programmatic alternatives.
A. Mandatory Cold Ironing Requirement
To provide earlier air quality benefits,
some commenters suggested adopting
earlier Tier 3 NOX standards and fuel
sulfur limits, requiring standards for
existing engines, and/or requiring the
use of shoreside power while ships are
at dock (called ‘‘cold-ironing’’).
Shoreside power is an effective way to
reduce emissions from ships while they
are at berth. The U.S. Navy is a pioneer
and has used cold-ironing successfully
PO 00000
Frm 00071
Fmt 4701
Sfmt 4702
for many years. However, to be
successful, this strategy requires
changes to both the ship and the port.
First, the ship must be equipped to use
shore power through changes to its
equipment and electrical systems. The
IMO, working with the International
Organization for Standardization (ISO),
is currently developing harmonized
requirements for these systems, and we
believe it would be more effective for
EPA to consider requiring such systems
once the technology is better defined.186
Second, the port terminal must ensure
that the electricity is available at the
berths. This is a significant barrier to the
adoption of shoreside power on a
national basis. However, some port
authorities already require cold-ironing
for frequent-calling vessels and are
pursuing additional reductions from
shoreside port equipment. The Ports of
Los Angeles, Long Beach, Seattle, and
Tacoma are among those with coldironing programs. EPA is working with
East Coast ports to develop plans for
shoreside power as part of port
development plans.
B. Earlier Adoption of CAA Tier 3
Standards
We considered a programmatic
alternative that would pull ahead the
CAA Tier 3 NOX standard from 2016 to
2014. This would require engine
manufacturers to apply SCR two years
earlier than they would be required to
under the MARPOL Annex VI program.
This option presents serious technical
feasibility challenges. Beginning in
2011, manufacturers will be introducing

IMO Secretariat’s invitation to ISO to make
recommendations regarding fuel characteristics and

new engine-based technologies to meet
the Tier 2 standards. We believe that
these new NOX-reducing technologies
and emission control approaches will
also be the basis for Tier 3 engine
designs. It will be necessary for
manufacturers to design, develop, and
validate these engine-based technologies
before they can be used in conjunction
with exhaust aftertreatment or
additional engine-based technologies
required to meet Tier 3 standards. Once
these Tier 2 technologies are mature and
well-understood, they can be further
refined and developed for use with the
additional NOX control technologies.
The original five-year period between
Tier 2 and Tier 3 was deemed
challenging but feasible for engine
manufacturers to design the Tier 3
engines and incorporate those engines
into new vessel designs. For this reason,
we do not believe it is technically
feasible to advance the Tier 3 standards
for new engines earlier.
Nevertheless, if such an alternative
were feasible, we can estimate the
inventory benefits associated with those
earlier NOX reductions. Cumulative
NOX emission reductions for the period
2014 to 2023 as a result of the
coordinated strategy presented in this
Federal Register notice are estimated to
be 3 million short tons NOX reduction
beyond the Tier 1 standards (Table IX–
1). Introducing the CAA Tier 3
standards two years earlier than
proposed would affect only U.S. vessels
and would reduce an additional 0.07
million short tons of reduction of NOX
beyond our coordinated strategy
through 2023. The method we used to
estimate these inventory impacts are
presented in the draft RIA, Appendix
3B.

Alternative 1 .............................................................................................................................................................................
(2014 NOX standards for U.S. Vessels) ..................................................................................................................................
Due to the technical concerns
described above, our review of this
alternative leads us to conclude that
advancing the introduction of the Tier 3
NOX standards is not a feasible way to
improve 2023 NOX reductions and
could create significant problems for
implementation of the overall
coordinated strategy. Nevertheless, we
request comment on this alternative and
whether it could be modified to improve
its feasibility.

C. Standards for Existing Engines
We examined a third programmatic
alternative, including improvements in
NOX emissions from pre-2016 engines.
A control program for existing engines
would help many areas, notably the
South Coast of California, to achieve
their ozone and PM NAAQS goals
through Category 3 engine NOX
reductions sooner than fleet turnover
would allow. In this section we describe
several methods to control emissions
from existing engines. We request
comment on all aspects of these
alternatives.
(1) Clean Air Act Remanufacturing
Program
Our recently-finalized emission
control program for marine diesel
engines up to 30 liters per cylinder
displacement includes standards that
will apply to existing engines at the
time they are remanufactured (73 FR
25098, May 6, 2008, at 25130). In that
program, we define ‘‘new marine
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
engine’’ to include an engine that has
been remanufactured, which is defined
as replacement of all cylinder liners,
either in one event or over a five-year
period. Vessel owners/operators and
engine rebuilders who remanufacture
those engines would be required to use
a certified remanufacture system when
an engine is remanufactured if such a
certified system is available; if there is
no certified kit, there is no requirement
until the time of the next remanufacture
event. The program applies to engines
with maximum engine power greater
than 600 kW and manufactured in 1973
or later, through Tier 2 (2012–14,
depending on engine size). A certified
marine remanufacture system must
achieve a 25 percent reduction in PM
emissions compared to the engine’s
measured baseline emissions level
without increasing NOX emissions.
The program, which is similar to
locomotive remanufacture program, was
possible to adopt under the Clean Air
Act because many commercial Category
1 and 2 engines undergo periodic full
like-new rebuilds to ensure their
dependability by returning the engine to
as-new condition. Many manufacturers
provide guidance for a full rebuild to asnew condition, which might include
replacing piston rings, heads, bearings,
and gear train/camshaft as well as
piston liners. Based on discussions with
engine manufacturers, we determined
that replacing all cylinder liners is a
simple and clear indicator that the
PO 00000
Frm 00072
Fmt 4701
Sfmt 4702
10,494,636
7,515,389
7,444,866
servicing being done is extensive
enough for the engine to be considered
functionally equivalent to a freshly
manufactured engine, both
mechanically and in terms of how it is
used. Therefore, we defined
remanufacture as the removal and
replacement of all cylinder liners, either
during a single maintenance event or
over a five-year period. Marine diesel
engines are not considered to be
remanufactured if the rebuilding
process falls short of this definition (i.e.,
the cylinder liners are removed and
replaced over more than a five-year
period).
We do not think it is possible to adopt
a similar program for Category 3 engines
at this time. Even though Category 3
engines may remain in the fleet for
several decades, they are not maintained
in the same way as Category 1 or
Category 2 engines. Category 3 engines
are very large, with cylinder sizes of 90
liters not uncommon. Maintenance for
these engines is very different than that
for Category 1 or Category 2 engines.
Specifically, piston liners, as well as
other engine components, are not
replaced unless there is a catastrophic
failure. Our analysis of available
information suggests that cylinder liners
for engines this large are inspected
based on hours of operation, with the
standard interval being about 6,000 to
12,000 hours for engines operating on
residual fuel and up to 25,000 hours for
engines operating on distillate fuel.

28AUP2
Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
Engine manufacturers specify how this
inspection is to be performed. Typically,
the liner is inspected, measured,
dressed, honed or replaced if beyond
specifications. As each cylinder has
individual wear characteristics, the
complete engine liner replacement is
not normally done on all cylinders at
one time, since this would be much
more expensive than the maintenance
according to the manufacturer
specifications. If there is an extended
drydock, it is possible that a ship owner
may take advantage of this time to
inspect and work on several or all
cylinders, but it is doubtful that a
complete cylinder liner replacement
would be done due to the expense.
These engines are an integral part of the
vessel design, and it would be difficult
to replace the cylinder liners if it is not
absolutely necessary.
Other maintenance occurs on a
cylinder-specific basis and is not
comprehensive enough to return the
engine to as-new condition. Finally,
engine manufacturers have informed us
that these engines are built to last, with
most vessels being scrapped before the
engine is worn out. Operating at lower
speeds (130 rpm) also reduces wear on
the cylinders.
Based on the above information and
because there is no specific
maintenance action common to all
Category 3 engines that (1) would return
an engine to as-new condition and (2)
could be used to identify engines as
being remanufactured and therefore
‘‘new,’’ we conclude it is not possible to
extend the marine remanufacture
program to Category 3 engines at this
time.
(2) MARPOL Annex VI Existing Engine
Program
MARPOL Annex VI has two sets of
NOX provisions that apply to existing
engines. These requirements will apply
to engines on U.S. vessels through the
Act to Prevent Pollution from Ships and
are briefly described in this section. In
addition to these NOX requirements,
MARPOL Annex VI will provide
significant PM reductions from existing
vessels through its fuel sulfur
requirements, particularly in a U.S.
ECA. These PM benefits are described
elsewhere in this Federal Register
notice.
First, Annex VI requires any engine
above 130 kW that undergoes a major
conversion to comply with the
standards that are in effect at the time
that major conversion takes place. Major
conversion means the engine is replaced
by a non-identical engine, an engine is
added to the vessel, the engine’s
maximum continuous rating is
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
increased by more than 10 percent, or
the engine undergoes any modification
that would increase its emissions.
Second, the recent amendments to
Annex VI add a provision that requires
all engines at or above 90 liters per
cylinder displacement and above 5,000
kW that were built between 1990
through 1999 to comply with the Tier I
NOX limits if there is a certified
Approved Method (remanufacture
system) for that engine. This kit-based
approach is similar to our domestic
program except it is triggered solely by
the existence of a certified
remanufacture system and does not also
require a specific remanufacture event
(i.e., replacing all cylinder liners either
all at once or within a period of five
years). The Tier 1 NOX limits are
appropriate for this group of engines
because they often are based on the
same or a similar engine platform as the
Tier 1 engines and the emission control
techniques that apply to Tier 1 engines
should also be applicable to many of the
pre-Tier 1 engines. Pre-1990 engines
were excluded from this program
because their base engine platforms can
be very different from Tier 1 engines;
because many of the original engine
manufacturers of these engines are no
longer in business; and because the
population of these engines is expected
to be too small in 2010 to warrant
emission controls. Engine
manufacturers are expected to begin
certifying Approved Methods when the
Annex amendments go into force in July
2010; owners will be required to install
the kits at the time of the first renewal
survey that occurs 12 months after the
kit is certified.
The combination of the Annex VI
existing engine program to reduce NOX
emissions from very large Category 3
engines and the Annex VI fuel sulfur
program will significantly reduce NOX
and PM emissions from existing vessels.
Because these requirements will apply
to Category 3 engines on U.S. and
foreign vessels through APPS, it is not
necessary to adopt these same
requirements under our Clean Air Act
authority to protect U.S. air quality or to
implement Annex VI.
(3) Voluntary Marine Verification
Program
We are considering a programmatic
alternative to encourage additional NOX
reductions from Category 3 engines on
ocean-going vessels. In combination
with state or local incentives, this
program would provide incentives for
owners to achieve, on a voluntary basis,
greater emission reductions earlier than
required for new Category 3 engines,
and to retrofit existing Category 3
PO 00000
Frm 00073
Fmt 4701
Sfmt 4702
44513
engines with more advanced NOX
emission control technologies.
In this approach, States, localities,
and ports would encourage vessel
owners to participate in this program
through specially-designed incentive
plans. This would allow States,
localities, and ports the flexibility to
tailor use of the program to their
specific needs.
To facilitate such state or local
programs, EPA would set up a voluntary
Marine Verification Program as an
extension of our current diesel retrofit
program. Under this program, we would
provide a verification, based on
simplified emission testing, for any
vessel owner who provides data to show
that the Category 3 propulsion engines
on the relevant vessel achieve a more
stringent tier of NOX limits, Tier 2 or
Tier 3, than otherwise applies to those
engines. While verification would not
be equivalent to EPA certification (the
base engine certification would remain
the same), it would provide assurance to
the states and localities that adopt such
programs that the emission reductions
are occurring. The test methods used to
make this demonstration would be the
same as those that would be used to
comply with the production testing
requirements for new engines (see
Section VI.A.1.d, above). The
verification could be periodically
reviewed to ensure the engine continues
to meet the verified emission levels.
This could occur at the time of the
vessel certification surveys required by
MARPOL Annex VI, either the
intermediate survey (every two and a
half years) or the renewal survey (every
five years).
The voluntary Marine Verification
Program would be available to Category
3 propulsion engines on new or existing
vessels, and would be based on
achieving the Tier 2 or Tier 3 NOX
limits and not on a percent reduction
from a baseline. Owners could achieve
these NOX limits by adjusting the
engine, retrofitting engine components,
or retrofitting with an aftertreatment
device. However, we would not
consider an exhaust gas scrubber to be
an acceptable control strategy for
reducing NOX emissions (see Section
V.C.2.b, above).
Unlike a remanufacture program,
which relies on the certification of
remanufacture systems that would
apply to all specified engines, the
Marine Verification Program would
apply to Category 3 propulsion engines
on a vessel-specific basis. It would be
up to the individual vessel owner to
determine how to reduce the NOX
emissions from the engines on a vessel,
and to demonstrate, per the testing

mstockstill on DSKH9S0YB1PROD with PROPOSALS2
44514
Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
protocols outlined above, that the
relevant engines achieve the more
stringent NOX limit. Note that an engine
verification would not create the
presumption that a verified retrofit
constitutes a remanufacture system or
Certified Approved Method that must be
applied to all engines of the same
model. However, we seek comment on
whether there are ways to approve
groups of engine in a verification to
reduce the cost of the program by
spreading design costs over more
engines.
Participation in the Marine
Verification Program would be
completely voluntary: no state, locality,
or port authority would be required to
adopt this program, and no vessel owner
would be required to retrofit a NOX
emission control technology.
We request comment on whether such
a voluntary program would be beneficial
to states and localities that seek earlier
NOX reductions, and whether port
authorities would take advantage of it in
the context of various incentive
programs.
We also seek comment on how such
a program could be applied in the
context of the MARPOL Annex VI
requirements for major conversions.
Specifically, Regulation 13 of Annex VI
requires that an engine that undergoes a
major conversion be certified to the NOX
limits in effect at the time of the major
conversion. A major conversion is
defined as replacing an existing engine
or adding an engine to a vessel,
increasing the maximum continuous
power of a vessel by more than ten
percent, or by substantially modifying
an engine. The NOX Technical Code
defines substantial modification as any
modification that ‘‘could potentially
cause the engine to exceed’’ the
Regulation 13 NOX limits. The NOX
Technical Code further specifies that, in
the case of engines installed on vessels
constructed before January 1, 2000, the
impact on emissions must be shown by
an emissions test. We do not think that
participation in a Voluntary Marine
Verification Program would trigger these
requirements since ships would not be
making adjustments that would increase
emissions. However, we seek comment
on whether they imply that a Portable
Emissions Measurement System
(PEMS)-based emission measurement
should not be used and the simplified
measurement methods contained in the
NOX Technical Code should be used
instead in order to be in compliance
with Annex VI and the NOX Technical
Code. If the latter is the case, we also
seek comment on the cost of such
emission measurement.

We seek comment on how the
MARPOL Annex VI documentation for
an engine, including its technical file,
would need to be adjusted for a verified
engine. We also seek comment on how
this program would apply to foreignflagged vessels. Specifically, if the
Substantial Modification provisions of
the NOX Technical Code are triggered by
the Voluntary Marine Verification
Program, it could also be necessary that
vessels built before 2000 obtain an
Engine International Air Pollution
Prevention certificate from its flag state
Administration. The ship could also be
required to obtain and maintain the
documentation that goes with it (Engine
Technical File, Record Book of Engine
Parameters). EPA would not be able to
re-issue an EIAPP for vessels not flagged
in the United States. It would be up to
participating vessel owners to obtain a
new EIAPP or a revised EIAPP from
their flag Administration. We seek
comment on whether this would
prevent owners from participating in the
program.
X. Public Participation
We request comment on all aspects of
the emission control program that we
are proposing under the CAA. This
section describes how you can
participate in this process.
A. How Do I Submit Comments?

XI. Statutory and Executive Order
Reviews
As explained in Section I.A, the
program we are proposing is part of a
coordinated strategy to address
emissions from ocean-going vessels.
That coordinated strategy includes,
among other actions, the combination
the global Tier 2 NOX standards
included in the amendments to Annex
VI and the ECA Tier 3 NOX limits and
fuel sulfur limits that will apply when
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
the U.S. coasts are designated as an ECA
through an additional amendment to
Annex VI. These engine and fuel
standards will be enforceable for all
vessels, U.S. and foreign, operating in
the United States through the Act to
Prevent Pollution from Ships. Because
the coordinated strategy in its entirety is
economically significant (see cost
analysis in Section V), the components
we are adopting in this rule (engine
controls for Category 3 engines on U.S.
vessels under our Clean Air Act
program, as required by section 213 of
the Act that are identical to the
MARPOL Annex VI NOX limits; limits
on hydrocarbon and carbon monoxide
emissions for Category 3 engines; PM
measurement requirement; changes to
our Clean Air Act diesel fuel program to
allow production and sale of ECAcompliant fuel; changes to our emission
control program for smaller marine
diesel engines to harmonize with the
Annex VI NOX requirements, for U.S.
vessels that operate internationally) may
also be considered to be economically
significant.
A. Executive Order 12866: Regulatory
Planning and Review
Under Executive Order (EO) 12866
(58 FR 51735, October 4, 1993), this
action is a ‘‘significant regulatory
action’’ because it raises novel legal or
policy issues due to the international
nature of the use of Category 3 marine
diesel engines. Accordingly, EPA
submitted this action to the Office of
Management and Budget (OMB) for
review under EO 12866 and any
changes made in response to OMB
recommendations have been
documented in the docket for this
action.
In addition, EPA prepared an analysis
of the potential costs and benefits
associated with our coordinated strategy
for controlling emissions from oceangoing vessels. While the costs of the
coordinated strategy are ‘‘significant,’’
the costs of the CAA program described
in this proposal are minimal, as
explained above in the introduction to
this section. This analysis is contained
in the draft Regulatory Impact Analysis
that was prepared, and is available in
the docket for this rulemaking and at the
docket Internet address listed under
ADDRESSES above.
B. Paperwork Reduction Act
The information collection
requirements in this proposed rule have
been submitted for approval to the
Office of Management and Budget
(OMB) under the Paperwork Reduction
Act, 44 U.S.C. 3501 et seq. The
Information Collection Request (ICR)
PO 00000
Frm 00075
Fmt 4701
Sfmt 4702
44515
document prepared by EPA has been
assigned EPA ICR Number 2345.01.
Section 208(a) of the Clean Air Act
requires that manufacturers provide
information the Administrator may
reasonably require to determine
compliance with the regulations;
submission of the information is
therefore mandatory. We will consider
confidential all information meeting the
requirements of section 208(c) of the
Clean Air Act. Recordkeeping and
reporting requirements for
manufacturers would be pursuant to the
authority of section 208 of the Clean Air
Act.
The data we require in this ICR is
necessary to comply with Title II of the
Clean Air Act, as amended in 1990. The
Act directs us to adopt regulations for
nonroad engines if we determine those
engines contribute significantly to air
pollution in the U.S. Now that we have
made this determination, the Act directs
us to set emission standards for any
category of nonroad engines that
contribute to air quality nonattainment
in two or more areas in the U.S. We can
only meet the requirements of the Act
by collecting data from the regulated
industry. Also, we will only have an
effective program if we know that these
engines maintain their certified
emission level throughout their
operating lives.
The burden for certification testing is
generally based on conducting two
engine tests for each engine family, then
using that test data for several years.
The manufacturer’s application for
certification involves an extensive effort
the first year, followed by relatively
little effort in subsequent years. We
estimate that manufacturers will
conduct new certification testing every
five years; the costs have been estimated
on an annual average basis. In addition
to testing, manufacturers must prepare
the application for certification and
maintain appropriate records. We have
estimated the cost of these combined
activities, which include engineering
and clerical effort, to be about $20,000
for each Category 3 marine diesel engine
per certification cycle. As with the
testing costs, we are presenting annual
average costs. The burden for
production-line testing is based on an
industry-wide calculation. Rebuilders,
including operators of marine vessels
with Category 3 engines, must keep
records as needed to show that rebuilt
engines continue to meet emission
standards, consistent with the
manufacturer’s original design. In
addition, owners and operators of
marine vessels with Category 3 engines
must record information about their
location when rebuilding engines or

making other adjustments and send
minimal annual notification to EPA to
show that engine maintenance and
adjustments have not caused engines to
be noncompliant. Burden is defined at
5 CFR 1320.3(b).
An agency may not conduct or
sponsor, and a person is not required to
respond to, a collection of information
unless it displays a currently valid OMB
control number. The OMB control
numbers for EPA’s regulations in 40
CFR are listed in 40 CFR part 9.
To comment on the Agency’s need for
this information, the accuracy of the
provided burden estimates, and any
suggested methods for minimizing
respondent burden, EPA has established
a public docket for this rule, which
includes this ICR, under Docket ID
number EPA–HQ–OAR–2007–0121.
Submit any comments related to the ICR
to EPA and OMB. See the ADDRESSES
section at the beginning of this notice
for where to submit comments to EPA.
Send comments to OMB at the Office of
Information and Regulatory Affairs,
Office of Management and Budget, 725
17th Street, NW., Washington, DC
20503, Attention: Desk Office for EPA.
Since OMB is required to make a
decision concerning the ICR between 30
and 60 days after August 28, 2009, a
comment to OMB is best assured of
having its full effect if OMB receives it
by September 28, 2009. The final rule
will respond to any OMB or public
comments on the information collection
requirements contained in this proposal.
C. Regulatory Flexibility Act
The Regulatory Flexibility Act (RFA)
generally requires an agency to prepare
a regulatory flexibility analysis of any
rule subject to notice and comment
rulemaking requirements under the
Administrative Procedure Act or any
other statute unless the agency certifies
that the rule will not have a significant
economic impact on a substantial
number of small entities. Small entities
include small businesses, small
organizations, and small governmental
jurisdictions.
For purposes of assessing the impacts
of this rule on small entities, small
entity is defined as: (1) A small business
that is primarily engaged in
manufacture of large diesel marine
engines as defined by NAICS code
333618 with 1,000 or fewer employees
(based on Small Business
Administration size standards) or a
small business primarily engaged in the
shipbuilding and repairing as defined
by NAICS code 336611 with 1,000 or
fewer employees (based on Small
Business Administration size
standards); (2) a small governmental
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
jurisdiction that is a government of a
city, county, town, school district or
special district with a population of less
than 50,000; and (3) a small
organization that is any not-for-profit
enterprise which is independently
owned and operated and is not
dominant in its field.
After considering the economic
impacts of today’s proposed rule on
small entities, I certify that this action
will not have a significant economic
impact on a substantial number of small
entities. This proposed rule will not
impose any requirements on small
entities. There are no small entities in
this regulated industry. We continue to
be interested in the potential impacts of
the proposed rule on small entities and
welcome comments on issues related to
such impacts.
D. Unfunded Mandates Reform Act
This rule does not contain a Federal
mandate that may result in expenditures
of $100 million or more for State, local,
and tribal governments, in the aggregate,
or the private sector in any one year.
While the costs of the coordinated
strategy exceed the $100 million per
year threshold for the private sector, the
costs of the components of that strategy
that are the subject of this rule are less
than $100 million per year, as explained
in the introduction to this section and
in Section VII. Therefore, this action is
not subject to the requirements of
Sections 202 or 205 of the UMRA. This
action is also not subject to the
requirements of Section 203 of UMRA
because it contains no regulatory
requirements that might significantly or
uniquely affect small governments.
E. Executive Order 13132: Federalism
Executive Order 13132, entitled
‘‘Federalism’’ (64 FR 43255, August 10,
1999), requires EPA to develop an
accountable process to ensure
‘‘meaningful and timely input by State
and local officials in the development of
regulatory policies that have federalism
implications.’’ ‘‘Policies that have
federalism implications’’ is defined in
the Executive Order to include
regulations that have ‘‘substantial direct
effects on the States, on the relationship
between the national government and
the States, or on the distribution of
power and responsibilities among the
various levels of government.’’
This proposed rule does not have
federalism implications. It will not have
substantial direct effects on the States,
on the relationship between the national
government and the States, or on the
distribution of power and
responsibilities among the various
levels of government, as specified in
PO 00000
Frm 00076
Fmt 4701
Sfmt 4702
Executive Order 13132. The proposed
rule will be implemented at the Federal
level and impose compliance
obligations only on private industry.
Thus, Executive Order 13132 does not
apply to this rule.
Although Section 6 of Executive
Order 13132 does not apply to this rule,
EPA did consult with representatives of
various State and local governments in
developing this rule. EPA consulted
with representatives from the National
Association of Clean Air Agencies
(NACAA, formerly STAPPA/ALAPCO),
the Northeast States for Coordinated Air
Use Management (NESCAUM), and the
California Air Resources Board (CARB).
In the spirit of Executive Order 13132,
and consistent with EPA policy to
promote communications between EPA
and State and local governments, EPA
specifically solicits comment on this
proposed rule from State and local
officials.
F. Executive Order 13175: Consultation
and Coordination With Indian Tribal
Governments
This proposed rule does not have
tribal implications, as specified in
Executive Order 13175 (65 FR 67249,
November 9, 2000). The rule will be
implemented at the Federal level and
impose compliance costs only on
manufacturers of marine engines and
marine vessels. Tribal governments will
be affected only to the extent they
purchase and use the regulated engines
and vehicles. Thus, Executive Order
13175 does not apply to this action.
G. Executive Order 13045: Protection of
Children From Environmental Health
and Safety Risks
This action is not subject to EO 13045
(62 FR 19885, April 23, 1997) because
it is not economically significant as
defined in EO 12866. While the costs of
the coordinated strategy are
‘‘significant,’’ the costs of the CAA
program described in this proposal are
minimal, as explained above in the
introduction to this section. The health
and risk assessments associated with the
coordinated strategy for controlling
emissions from ocean-going vessels are
contained in Section II.A of the
preamble and Chapter 2 of the draft RIA,
which has been placed in the public
docket under Docket ID number EPA–
HQ–OAR–2007–0121.
The public is invited to submit or
identify peer-reviewed studies and data,
of which EPA may not be aware, that
assessed results of early life exposure to
the pollutants addressed by this
proposed rule.

H. Executive Order 13211: Actions That
Significantly Affect Energy Supply,
Distribution, or Use
Executive Order 13211, ‘‘Actions
Concerning Regulations That
Significantly Affect Energy Supply,
Distribution, or Use’’ (66 FR 28355 (May
22, 2001)), requires EPA to prepare and
submit a Statement of Energy Effects to
the Administrator of the Office of
Information and Regulatory Affairs,
Office of Management and Budget, for
certain actions identified as ‘‘significant
energy actions.’’ Section 4(b) of
Executive Order 13211 defines
‘‘significant energy actions’’ as ‘‘any
action by an agency (normally
published in the Federal Register) that
promulgates or is expected to lead to the
promulgation of a final rule or
regulation, including notices of inquiry,
advance notices of proposed
rulemaking, and notices of proposed
rulemaking: (1)(i) That is a significant
regulatory action under Executive Order
12866 or any successor order, and (ii) is
likely to have a significant adverse effect
on the supply, distribution, or use of
energy; or (2) that is designated by the
Administrator of the Office of
Information and Regulatory Affairs as a
significant energy action.’’ We have
prepared a Statement of Energy Effects
for this action as follows.
This rule’s potential effects on energy
supply, distribution, or use have been
analyzed and are discussed in detail in
Section 4.6 of the RIA. In summary,
while we project that this rule would
result in an energy effect that exceeds
the 10,000 barrel per day change in
crude oil production threshold noted in
E.O. 13211, this rule does not
significantly affect the energy use,
production, or distribution beyond what
is required by Annex VI of the
International Convention for the
Prevention of Pollution from Ships.

I. National Technology Transfer
Advancement Act
Section 12(d) of the National
Technology Transfer and Advancement
Act of 1995 (‘‘NTTAA’’), Public Law
104–113, 12(d) (15 U.S.C. 272 note)
directs EPA to use voluntary consensus
standards in its regulatory activities
unless to do so would be inconsistent
with applicable law or otherwise
impractical. Voluntary consensus
standards are technical standards (e.g.,
materials specifications, test methods,
sampling procedures, and business
practices) that are developed or adopted
by voluntary consensus standards
bodies. The NTTAA directs EPA to
provide Congress, through OMB,
explanations when the Agency decides
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
not to use available and applicable
voluntary consensus standards.
The proposed rulemaking involves
technical standards. Therefore, the
Agency conducted a search to identify
potentially applicable voluntary
consensus standards. The International
Organization for Standardization has a
voluntary consensus standard that can
be used to test engines. However, the
test procedures in this proposal reflect
a level of development that goes
substantially beyond the ISO or other
published procedures. The proposed
procedures incorporate new
specifications for steady-state emission
measurements and measuring emissions
using field-testing procedures. The
procedures we adopt in this rule will
form the working template for ISO and
national and state governments to define
test procedures for measuring engine
emissions. As such, we have worked
extensively with the representatives of
other governments, testing
organizations, and the affected
industries.
EPA welcomes comments on this
aspect of the proposed rulemaking and,
specifically, invites the public to
identify potentially-applicable
voluntary consensus standards and to
explain why such standards should be
used in this regulation.
J. Executive Order 12898: Federal
Actions To Address Environmental
Justice in Minority Populations and
Low-Income Populations
Executive Order (EO) 12898 (59 FR
7629 (Feb. 16, 1994)) establishes Federal
executive policy on environmental
justice. Its main provision directs
Federal agencies, to the greatest extent
practicable and permitted by law, to
make environmental justice part of their
mission by identifying and addressing,
as appropriate, disproportionately high
and adverse human health or
environmental effects of their programs,
policies, and activities on minority
populations and low-income
populations in the United States.
EPA has determined that this
proposed rule will not have
disproportionately high and adverse
human health or environmental effects
on minority or low-income populations
because it increases the level of
environmental protection for all affected
populations without having any
disproportionately high and adverse
human health or environmental effects
on any population, including any
minority or low-income population.
Together, this proposed rule which
addresses emissions from domesticflagged vessels and the joint U.S./
Canada ECA application to the IMO
PO 00000
Frm 00077
Fmt 4701
Sfmt 4702
44517
which addresses emissions from
foreign-flagged vessels (referred to as the
‘‘coordinated strategy’’) will achieve
significant reductions of various
emissions from Category 3 marine diesel
engines, including NOX, SOX, and direct
PM. Exposure to these pollutants raises
concerns regarding environmental
health for the U.S. population in general
including the minority populations and
low-income populations that are the
focus of the environmental justice
executive order.
The emission reductions from the
new standards in the coordinated
strategy will have large beneficial effects
on communities in proximity to port,
harbor, and waterway locations,
including low-income and minority
communities. In addition to exhaust
emission standards for freshly
manufactured and remanufactured
engines, the coordinated strategy, if
finalized, would further reduce
emissions from regulated engines that
directly impact low-income and
minority communities.
EPA recently updated its initial
screening-level analysis of selected
marine port areas to better understand
the populations, including minority and
low-income populations, that are
exposed to diesel PM emission sources
from these facilities.187, 188 This
screening-level analysis is an inexact
tool and should only be considered for
illustrative purposes to help understand
potential impacts. The analysis
included all emission sources as well as
ocean-going marine diesel engines, and
focused on a representative selection of
national marine ports (45 ports
total).189, 190 Considering only oceangoing marine engine diesel PM
emissions, the results indicate that 6.5
million people are exposed to ambient
diesel PM levels that are 2.0 μg/m3 and
0.2 μg/m3 above levels found in areas
further from these facilities. This
population includes a disproportionate

African-Americans, and Hispanics. The
results from all emission sources show
that nearly 18 million people are
exposed to higher levels of diesel PM
from all sources at the marine port areas
than urban background levels. Because
those living in the vicinity of marine
ports are more likely to be low-income
households and minority residents,
these populations would receive a
significant benefit from the combined
coordinated strategy. See Section VIII of
this preamble and Chapter 6 of the draft
RIA for a discussion on the benefits of
this rule, including the benefits to

Subpart X—[Amended]
40. A new § 85.2306 is added to
subpart X to read as follows:
§ 85.2306 Inventory and stockpiling
provisions related to new emission
standards for heavy-duty engines.
(a) Notwithstanding any other
provision of this subpart, a vehicle
manufacturer may not sell, offer for sale,
or introduce or deliver into commerce
in the United States or import into the
United States any new heavy-duty
engine or vehicle equipped with a new
heavy-duty engine after emission
standards take effect for that engine or
vehicle, unless the engine has an
appropriate certificate of conformity or
exemption. An appropriate certificate of
conformity is one that applies for the
same model year as the model year of
the vehicle or that shows conformity
with the same standards as engines
manufactured in the model year of the
vehicle (except as provided in
paragraph (b) of this section).
(b) If new emission standards apply in
a given model year, a new vehicle in
that model year must be powered by an
engine that is certified to the new
standards, except that a manufacturer
may continue to use up its normal
inventory of earlier engines that were
built before the date of the new or
changed standards. For example, if a
manufacturer’s normal inventory
practice is to keep on hand a one-month
supply of engines based on its
upcoming production schedule, a
manufacturer may order engines in
anticipation of the 2010 emission
standards based on its normal inventory
requirements late in the engine
manufacturer’s 2009 model year and
install those engines in the
manufacturer’s vehicle, regardless of the
date of installation. Also, if an
equipment manufacturer’s model year
starts before the end of the calendar year
preceding new standards, the
equipment manufacturer may use
engines from the previous model year
for equipment produced before January
E:\FR\FM\28AUP2.SGM
28AUP2
Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
1 of the year that new standards apply.
If emission standards for the engine do
not change in a given model year, an
equipment manufacturer may continue
to install engines from the previous
model year without restriction. Vehicle
and engine manufacturers may not
circumvent the provisions in paragraph
(a) of this section by stockpiling engines
(i.e., acquiring more engines than
normal for inventory) that were built
before new or changed standards take
effect or stockpiling engines that
otherwise fail to have an appropriate
certificate of conformity as provided in
paragraph (a) of this section. Note that
this allowance does not apply for
vehicles subject to vehicle-based
standards.
(c) A heavy-duty engine
manufacturer, who otherwise produces
engines covered by an appropriate
certificate of conformity, may not cause
or otherwise aid a vehicle manufacturer
to fail to comply with paragraphs (a)
and (b) of this section.
(d) Exemptions from certification
requirements are described in subpart R
of this part and apply as appropriate to

(a) This part includes various
requirements to record data or other
information. Refer to § 1033.925 and 40
CFR 1068.25 regarding recordkeeping
requirements. If recordkeeping
requirements are not specified, store
these records in any format and on any
media and keep them readily available
for one year after you send an associated
application for certification, or one year
after you generate the data if they do not
support an application for certification.
You must promptly send us organized,
written records in English if we ask for
them. We may review them at any time.
(b) The regulations in § 1033.255 and
40 CFR 1068.101 describe your
obligation to report truthful and
complete information and the
consequences of failing to meet this
obligation. This includes information
not related to certification.

(d) Averaging, banking, and trading.
You may generate or use emission
credits under the averaging, banking,
and trading (ABT) program as described
in subpart H of this part to comply with
the NOX and/or PM standards of this
part. You may also use ABT to comply
with the Tier 4 HC standards of this part
as described in paragraph (j) of this
section. Generating or using emission
credits requires that you specify a
family emission limit (FEL) for each
pollutant you include in the ABT
program for each engine family. These
FELs serve as the emission standards for
the engine family with respect to all
required testing instead of the standards
specified in paragraphs (a) and (b) of
this section. FELs may not be higher
than the following limits:
(1) FELs for Tier 0 and Tier 1
locomotives originally manufactured
before 2002 may have any value.
(2) FELs for Tier 1 locomotives
originally manufactured 2002 through
2004 may not exceed 9.5 g/bhp-hr for
NOX emissions or 0.60 g/bhp-hr for PM
emissions measured over the line-haul
duty cycle. FELs for these locomotives
may not exceed 14.4 g/bhp-hr for NOX
emissions or 0.72 g/bhp-hr for PM
emissions measured over the switch

regulated pollutant. This includes
components listed in 40 CFR part 1068,
Appendix I, and components from any
other system you develop to control
emissions. The emission-related
warranty covers the components you
sell even if another company produces
the component. Your emission-related
warranty does not cover components
whose failure would not increase a
locomotive’s emissions of any regulated
pollutant. For remanufactured
locomotives, your emission-related
warranty is required to cover only those
parts that you supply or those parts for
which you specify allowable part
manufacturers. It does not need to cover
used parts that are not replaced during
the remanufacture.

(4) Estimate costs as described in this
paragraph (a)(4).
(i) The cost limits described in
paragraph (a)(1) of this section are
specified in terms of 2007 dollars.
Adjust these values for future years
according to the following equation:
Actual Limit = (2007 Limit) × [(0.6000)
× (Commodity Index) + (0.4000) ×
(Earnings Index)
Where:
2007 Limit = The value specified in
paragraph (a)(1) of this section ($250,000
or $125,000).
Commodity Index = The U.S. Bureau of
Labor Statistics Producer Price Index for
Industrial Commodities Less Fuel (Series
WPU03T15M05) for the month prior to
the date you submit your application
divided by 173.1.
Earnings Index = The U.S. Bureau of Labor
Statistics Estimated Average Hourly
Earnings of Production Workers for
Durable Manufacturing (Series
CES3100000008) for the month prior to
the date you submit your application
divided by 18.26.
(ii) Calculate all costs in current
dollars (for the month prior to the date
you submit your application). Calculate
fuel costs based on a fuel price adjusted
by the Association of American
Railroads’ monthly railroad fuel price
index (P), which is available at https: //
www.aar.org/~/media/AAR/RailCost
Indexes/Index_MonthlyFuelPrices.ashx.
(Use the value for the column in which
P equals 539.8 for November 2007.)

Subpart C—[Amended]
93. Section 1033.220 is amended by
revising the introductory text and
paragraph (a) to read as follows:
§ 1033.220 Amending maintenance
instructions.
You may amend your emissionrelated maintenance instructions after
you submit your application for
certification, as long as the amended
instructions remain consistent with the
provisions of § 1033.125. You must send
the Designated Compliance Officer a
request to amend your application for
certification for an engine family if you
want to change the emission-related
maintenance instructions in a way that
could affect emissions. In your request,
describe the proposed changes to the
maintenance instructions. If owners/
operators follow the original
maintenance instructions rather than
the newly specified maintenance, this
does not allow you to disqualify those
locomotives from in-use testing or deny
a warranty claim.
(a) If you are decreasing or
eliminating any of the specified
maintenance, you may distribute the
new maintenance instructions to your
customers 30 days after we receive your
request, unless we disapprove your
request. This would generally include
replacing one maintenance step with
another. We may approve a shorter time
or waive this requirement.
*

94. Section 1033.225 is amended by
revising paragraphs (b)(2), (e), and (f) to

(b) * * *
(2) Include engineering evaluations or
data showing that the amended engine
family complies with all applicable
requirements. You may do this by
showing that the original emission-data
locomotive is still appropriate for
showing that the amended family
complies with all applicable
requirements.
*
*
*
*
*
(e) For engine families already
covered by a certificate of conformity,
you may start producing the new or
modified locomotive anytime after you
send us your amended application,
before we make a decision under
paragraph (d) of this section. However,
if we determine that the affected
VerDate Nov<24>2008

Jkt 217001
locomotives do not meet applicable
requirements, we will notify you to
cease production of the locomotives and
may require you to recall the
locomotives at no expense to the owner.
Choosing to produce locomotives under
this paragraph (e) is deemed to be
consent to recall all locomotives that we
determine do not meet applicable
emission standards or other
requirements and to remedy the
nonconformity at no expense to the
owner. If you do not provide
information required under paragraph
(c) of this section within 30 days after
we request it, you must stop producing
the new or modified locomotives.
(f) You may ask us to approve a
change to your FEL in certain cases after
the start of production. The changed
FEL may not apply to locomotives you
have already introduced into U.S.
commerce, except as described in this
paragraph (f). If we approve a changed
FEL after the start of production, you
must include the new FEL on the
emission control information label for
all locomotives produced after the
change. You may ask us to approve a
change to your FEL in the following
cases:
(1) You may ask to raise your FEL for
your engine family at any time. In your
request, you must show that you will
still be able to meet the emission
standards as specified in subparts B and
H of this part. If you amend your
application by submitting new test data
to include a newly added or modified
locomotive, as described in paragraph
(b)(3) of this section, use the appropriate
FELs with corresponding production
volumes to calculate emission credits
for the model year, as described in
subpart H of this part. In all other
circumstances, you must use the higher
FEL for the entire family to calculate
emission credits under subpart H of this
part.
(2) You may ask to lower the FEL for
your emission family only if you have
test data from production locomotives
showing that emissions are below the
proposed lower FEL. The lower FEL
applies only to engines or fuel-system
components you produce after we
approve the new FEL. Use the
appropriate FELs with corresponding
production volumes to calculate
emission credits for the model year, as
described in subpart H of this part.

(c) We may measure emissions from
any of your emission-data locomotives
or other locomotives from the engine
family.
(1) We may decide to do the testing
at your plant or any other facility. If we
do this, you must deliver the locomotive
to a test facility we designate. If we do
the testing at your plant, you must
schedule it as soon as possible and
make available the instruments,
personnel, and equipment we need.
(2) If we measure emissions from one
of your locomotives, the results of that
testing become the official emission
results for the locomotive. Unless we
later invalidate these data, we may
decide not to consider your data in
determining if your engine family meets
applicable requirements.
(3) Before we test one of your
locomotives, we may set its adjustable
parameters to any point within the
adjustable ranges (see § 1033.115(b)).
(4) Before we test one of your
locomotives, we may calibrate it within
normal production tolerances for
anything we do not consider an
adjustable parameter. For example, this
would apply where we determine that
an engine parameter is not an adjustable
parameter (as defined in § 1042.901) but
that it is subject to production
variability.
(d) You may ask to use carryover
emission data from a previous model
year instead of doing new tests if all the
following are true:

(h) Calculation adjustments for
energy-saving design features. The
provisions of this paragraph (h) apply
for locomotives equipped with new
energy-saving locomotive design
features. They do not apply for features
that only improve the engine’s brakespecific fuel consumption. They also do
not apply for features that were
commonly incorporated in locomotives
before 2008.
(1) Manufacturers/remanufacturers
choosing to adjust emissions under this
paragraph (h) must do all of the
following for certification:
(i) Describe the energy-saving features
in your application for certification.
(ii) Describe in your installation
instruction and/or maintenance
instructions all steps necessary to utilize
the energy-saving features.
(2) If your design feature will also
affect the locomotives’ duty cycle, you
must comply with the requirements of
paragraph (g) of this section.
(3) Calculate the energy savings as
described in this paragraph (h)(3).
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
(i) Estimate the expected mean in-use
fuel consumption rate (on a BTU per
ton-mile basis) with and without the
energy saving design feature, consistent
with the specifications of paragraph
(h)(4) of this section. The energy savings
is the ratio of fuel consumed from a
locomotive operating with the new
feature to fuel consumed from a
locomotive operating without the
feature under identical conditions.
Include an estimate of the 80 percent
confidence interval for your estimate of
the mean, and other statistical
parameters we specify.
(ii) Your estimate must be based on
in-use operating data, consistent with
good engineering judgment. Where we
have previously certified your design
feature under this paragraph (h), we
may require you to update your analysis
based on all new data that are available.
You must obtain preliminary approval
before you begin collecting operational
data for this purpose.
(iii) We may allow you to consider the
effects of your design feature separately
for different route types, regions, or
railroads. We may require that you
certify these different locomotives in
different engine families and may
restrict their use to the specified
applications.
(iv) Design your test plan so that the
operation of the locomotives with and
without is as similar as possible in all
material aspects (other than the design
feature being evaluated). Correct all data
for any relevant differences, consistent
with good engineering judgment.
(v) Do not include any brake-specific
energy savings in your calculated
values. If it is not possible to exclude
such effects from your data gathering,
you must correct for these effects,
consistent with good engineering
judgment.
(4) Calculate adjustment factors as
described in this paragraph (h)(4). If the
energy savings will apply broadly,
calculate and apply the adjustment on a
cycle-weighted basis. Otherwise,
calculate and apply the adjustment
separately for each notch. To apply the
adjustment, multiply the emissions
(either cycle-weighted or notch-specific,
as applicable) by the adjustment. Use
the lower bound of the 80 percent
confidence interval of the estimate of
the mean as your estimated energy
savings rate. We may cap your energy
savings rate for this paragraph (h)(4) at
80 percent of the estimate of the mean.
Calculate the emission adjustment
factors as:
AF = 1.000 ¥ (energy savings rate)
(5) We may require you to collect and
report data from locomotives we allow
you to certify under this paragraph (h)

(a) * * *
(1) Before being installed in the
locomotive, the engines were covered by
a certificate of conformity issued under
40 CFR Part 1039 (or part 89) that is
effective for the calendar year in which
the manufacture or remanufacture
occurs. You may use engines certified
during the previous years if they were
subject to the same standards. You may
not make any modifications to the
engines unless we approve them.
*

(b) To certify your locomotives by
design under this section, submit your
application as specified in § 1033.205,
with the following exceptions:
(1) Include the following instead of
the locomotive test data otherwise
required by § 1033.205:
(i) A description of the engines to be
used, including the name of the engine
manufacturer and engine family
identifier for the engines.
(ii) A brief engineering analysis
describing how the engine’s emission
controls will function when installed in
the locomotive throughout the
locomotive’s useful life.
(iii) The emission data submitted
under 40 CFR part 1039 (or part 89).
(2) You may separately submit some
of the information required by
§ 1033.205, consistent with the

(a) Uncertified locomotives.
Locomotives covered by an export
exemption under 40 CFR 1068.230 may
be introduced into U.S. commerce prior
to being exported, but may not be used
in any revenue generating service in the
U.S. Locomotives covered by this
paragraph (a) may not include any EPA
emission control information label.
Such locomotives may include emission
control information labels for the
country to which they are being
exported.
(b) Locomotives covered by exportonly certificates. Locomotives may be

certified engine family may be exported
without restriction. Note that § 1033.705
requires that exported locomotives be
excluded from emission credit
calculations in certain circumstances.
(d) Locomotives certified to FELs
above the standards. The provisions of
this paragraph (d) apply for locomotive
configurations included in engine
families certified to one or more FELs
above any otherwise applicable
standard. Individual locomotives that
will be exported may be excluded from
an engine family if they are unlabeled.
For locomotives that were labeled
during production, you may remove the
emission control information labels
prior to export. All unlabeled
locomotives that will be exported are

(a) Banking is the retention of
emission credits by the manufacturer/
remanufacturer generating the emission
credits (or owner/operator, in the case of
transferred credits) for use in future
model years for averaging, trading, or
transferring. You may use banked
emission credits only as allowed by
§ 1033.740.
(b) You may designate any emission
credits you plan to bank in the reports
you submit under § 1042.730. During
the model year and before the due date
for the final report, you may designate
your reserved emission credits for
averaging, trading, or transferring.
(c) Reserved credits become actual
emission credits when you submit your
final report. However, we may revoke
these emission credits if we are unable
to verify them after reviewing your
reports or auditing your records.

may not use emission credits for any
engines if you do not keep all the
records required under this section. You
must therefore keep these records to
continue to bank valid credits. Store
these records in any format and on any
media, as long as you can promptly
send us organized, written records in
English if we ask for them. You must
keep these records readily available. We
may review them at any time.

(d) Keep records of the engine
identification number for each
locomotive you produce that generates
or uses emission credits under the ABT
program. If you change the FEL after the
start of production, identify the date you
started using each FEL and the range of
engine identification numbers
associated with each FEL. You must
also be able to identify the purchaser
and destination for each engine you
produce.

*
*
*
*
Alcohol-fueled locomotive means a
locomotive with an engine that is
designed to run using an alcohol fuel.
For purposes of this definition, alcohol
fuels do not include fuels with a
nominal alcohol content below 25
percent by volume.
*
*
*
*
*
Carryover means relating to
certification based on emission data
generated from an earlier model year as
described in § 1033.235(d). This
generally requires that the locomotives
in the engine family do not differ in any
aspect related to emissions.
*
*
*
*
*
Total hydrocarbon has the meaning
given in 40 CFR 1065.1001. This
generally means the combined mass of
organic compounds measured by the
specified procedure for measuring total
hydrocarbon, expressed as a
hydrocarbon with a hydrogen-to-carbon
mass ratio of 1.85:1.
Total hydrocarbon equivalent has the
meaning given in 40 CFR 1065.1001.
This generally means the sum of the
carbon mass contributions of nonoxygenated hydrocarbons, alcohols and
aldehydes, or other organic compounds
that are measured separately as
contained in a gas sample, expressed as
exhaust hydrocarbon from petroleumfueled locomotives. The hydrogen-tocarbon mass ratio of the equivalent
hydrocarbon is 1.85:1.
*
*
*
*
*
Useful life means the period during
which the locomotive engine is
designed to properly function in terms
of reliability and fuel consumption,
without being remanufactured, specified
as work output or miles. It is the period
during which a locomotive is required
to comply with all applicable emission
standards. See § 1033.101(g).

§ 1039.220 How do I amend the
maintenance instructions in my
application?
You may amend your emissionrelated maintenance instructions after
you submit your application for
certification as long as the amended
instructions remain consistent with the
provisions of § 1039.125. You must send
the Designated Compliance Officer a
written request to amend your
application for certification for an
engine family if you want to change the
emission-related maintenance
instructions in a way that could affect
emissions. In your request, describe the
proposed changes to the maintenance
instructions. If operators follow the
original maintenance instructions rather
than the newly specified maintenance,
this does not allow you to disqualify
those engines from in-use testing or
deny a warranty claim.
(a) If you are decreasing or
eliminating any specified maintenance,
you may distribute the new
maintenance instructions to your
customers 30 days after we receive your
request, unless we disapprove your
request. This would generally include
replacing one maintenance step with
another. We may approve a shorter time
or waive this requirement.
(b) If your requested change would
not decrease the specified maintenance,
you may distribute the new
maintenance instructions anytime after
you send your request. For example,
this paragraph (b) would cover adding
instructions to increase the frequency of
filter changes for engines in severe-duty
applications.
(c) You need not request approval if
you are making only minor corrections
(such as correcting typographical
mistakes), clarifying your maintenance
instructions, or changing instructions
for maintenance unrelated to emission
control. We may ask you to send us
copies of maintenance instructions
revised under this paragraph (c).
120. Section 1039.225 is amended by
revising paragraphs (b)(2), (e), and (f) to

(e) For engine families already
covered by a certificate of conformity,
you may start producing the new or
modified engine configuration anytime
after you send us your amended
application and before we make a
decision under paragraph (d) of this
section. However, if we determine that
the affected engines do not meet
applicable requirements, we will notify
you to cease production of the engines
and may require you to recall the
engines at no expense to the owner.
Choosing to produce engines under this
paragraph (e) is deemed to be consent to
recall all engines that we determine do
not meet applicable emission standards
or other requirements and to remedy the
nonconformity at no expense to the
owner. If you do not provide
information required under paragraph
(c) of this section within 30 days after
we request it, you must stop producing
the new or modified engines.
(f) You may ask us to approve a
change to your FEL in certain cases after
the start of production. The changed
FEL may not apply to engines you have
already introduced into U.S. commerce,
except as described in this paragraph (f).
If we approve a changed FEL after the
start of production, you must include
the new FEL on the emission control
information label for all engines
produced after the change. You may ask
us to approve a change to your FEL in
the following cases:
(1) You may ask to raise your FEL for
your engine family at any time. In your
request, you must show that you will
still be able to meet the emission
standards as specified in subparts B and
H of this part. If you amend your
application by submitting new test data
to include a newly added or modified
engine, as described in paragraph (b)(3)
of this section, use the appropriate FELs
with corresponding production volumes
to calculate emission credits for the
model year, as described in subpart H of
this part. In all other circumstances, you
must use the higher FEL for the entire
engine family to calculate emission
credits under subpart H of this part.
(2) You may ask to lower the FEL for
your engine family only if you have test
data from production engines showing
that emissions are below the proposed
lower FEL. The lower FEL applies only
to engines you produce after we approve
the new FEL. Use the appropriate FELs
with corresponding production volumes
to calculate emission credits for the
model year, as described in subpart H of
this part.

introductory text to read as follows:
§ 1039.235 What emission testing must I
perform for my application for a certificate
of conformity?
*
*
*
*
*
(c) We may measure emissions from
any of your emission-data engines or
other engines from the engine family, as
follows:
(1) We may decide to do the testing
at your plant or any other facility. If we
do this, you must deliver the engine to
a test facility we designate. The engine
you provide must include appropriate
manifolds, aftertreatment devices,
electronic control units, and other
emission-related components not
normally attached directly to the engine
block. If we do the testing at your plant,
you must schedule it as soon as possible
and make available the instruments,
personnel, and equipment we need.
(2) If we measure emissions on one of
your engines, the results of that testing
become the official emission results for
the engine. Unless we later invalidate
these data, we may decide not to
consider your data in determining if
your engine family meets applicable
requirements.
(3) Before we test one of your engines,
we may set its adjustable parameters to
any point within the physically
adjustable ranges (see § 1039.115(e)).
E:\FR\FM\28AUP2.SGM
28AUP2
Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
(4) Before we test one of your engines,
we may calibrate it within normal
production tolerances for anything we
do not consider an adjustable parameter.
For example, this would apply where
we determine that an engine parameter
is not an adjustable parameter (as
defined in § 1039.801) but that it is
subject to production variability.
(d) You may ask to use carryover
emission data from a previous model
year instead of doing new tests, but only
if all the following are true:
*
*
*
*

123. Section 1039.240 is amended by
revising paragraphs (a), (b), and (c)(1) to
read as follows:
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
§ 1039.240 How do I demonstrate that my
engine family complies with exhaust
emission standards?
(a) For purposes of certification, your
engine family is considered in
compliance with the emission standards
in § 1039.101(a) and (b), § 1039.102(a)
and (b), § 1039.104, and § 1039.105 if all
emission-data engines representing that
family have test results showing
deteriorated emission levels at or below
these standards. This includes all test
points over the course of the durability
demonstration. Note that your FELs are
considered to be the applicable
emission standards with which you
must comply if you participate in the
ABT program in subpart H of this part.
(b) Your engine family is deemed not
to comply if any emission-data engine
representing that family has test results
showing a deteriorated emission level
for any pollutant that is above an
applicable emission standard. Similarly,
your engine family is deemed not to
comply if any emission-data engine
representing that family has test results
showing any emission level above the
applicable not-to-exceed emission
standard for any pollutant. This
includes all test points over the course
of the durability demonstration.
(c) * * *
(1) Additive deterioration factor for
exhaust emissions. Except as specified
in paragraph (c)(2) of this section, use
an additive deterioration factor for
exhaust emissions. An additive
deterioration factor is the difference
between exhaust emissions at the end of
the useful life and exhaust emissions at
the low-hour test point. In these cases,
adjust the official emission results for
each tested engine at the selected test
point by adding the factor to the
measured emissions. If the factor is less
than zero, use zero. Additive
deterioration factors must be specified
to one more decimal place than the
applicable standard.

This section describes how to
determine deterioration factors, either
with an engineering analysis, with preexisting test data, or with new emission
measurements. Apply these

What definitions apply to this
*
*
*
*
*
Alcohol-fueled engine means an
engine that is designed to run using an
alcohol fuel. For purposes of this
definition, alcohol fuels do not include
fuels with a nominal alcohol content
below 25 percent by volume.
*
*
*
*
*
Carryover means relating to
certification based on emission data
generated from an earlier model year as
described in § 1042.235(d). This
generally requires that the engines in
the engine family do not differ in any
aspect related to emissions.
*
*
*
*
*
Date of manufacture has the meaning
given in 40 CFR 1068.30.
*
*
*
*
*
Model year means one of the
following things:
(1) For freshly manufactured
equipment and engines (see definition
of ‘‘new nonroad engine,’’ paragraph
(1)), model year means one of the
following:
(i) Calendar year.
(ii) Your annual new model
production period if it is different than
the calendar year. This must include
January 1 of the calendar year for which
the model year is named. It may not
begin before January 2 of the previous
calendar year and it must end by
December 31 of the named calendar
year.
(2) For an engine that is converted to
a nonroad engine after being placed into
service as a stationary engine, or being
certified and placed into service as a
motor vehicle engine, model year means
the calendar year in which the engine
was originally produced. For a motor
vehicle engine that is converted to be a
nonroad engine without having been
certified, model year means the calendar
year in which the engine becomes a new
nonroad engine. (See definition of ‘‘new
nonroad engine,’’ paragraph (2).)
(3) For a nonroad engine excluded
under § 1039.5 that is later converted to
operate in an application that is not
excluded, model year means the
calendar year in which the engine was
originally produced (see definition of
‘‘new nonroad engine,’’ paragraph (3)).
(4) For engines that are not freshly
manufactured but are installed in new
nonroad equipment, model year means
the calendar year in which the engine is
installed in the new nonroad equipment
(see definition of ‘‘new nonroad
engine,’’ paragraph (4)).
(5) For imported engines:
(i) For imported engines described in
paragraph (5)(i) of the definition of

mstockstill on DSKH9S0YB1PROD with PROPOSALS2
Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
‘‘new nonroad engine,’’ model year has
the meaning given in paragraphs (1)
through (4) of this definition.
(ii) For imported engines described in
paragraph (5)(ii) of the definition of
‘‘new nonroad engine,’’ model year has
the meaning given in 40 CFR 89.602 for
independent commercial importers.
(iii) For imported engines described
in paragraph (5)(iii) of the definition of
‘‘new nonroad engine,’’ model year
means the calendar year in which the
engine is assembled in its imported
configuration, unless specified
otherwise in this part or in 40 CFR part
1068.
*
*
*
*
*
New nonroad engine means any of the
following things:
(1) A freshly manufactured nonroad
engine for which the ultimate purchaser
has never received the equitable or legal
title. This kind of engine might
commonly be thought of as ‘‘brand
new.’’ In the case of this paragraph (1),
the engine is new from the time it is
produced until the ultimate purchaser
receives the title or the product is
placed into service, whichever comes
first.
(2) An engine originally manufactured
as a motor vehicle engine or a stationary
engine that is later used or intended to
be used in a piece of nonroad
equipment. In this case, the engine is no
longer a motor vehicle or stationary
engine and becomes a ‘‘new nonroad
engine.’’ The engine is no longer new
when it is placed into nonroad service.
This paragraph (2) applies if a motor
vehicle engine or a stationary engine is
installed in nonroad equipment, or if a
motor vehicle or a piece of stationary
equipment is modified (or moved) to
become nonroad equipment.
(3) A nonroad engine that has been
previously placed into service in an
application we exclude under § 1039.5,
when that engine is installed in a piece
of equipment that is covered by this part
1039. The engine is no longer new when
it is placed into nonroad service covered
by this part 1039. For example, this
would apply to marine diesel engine
that is no longer used in a marine vessel
but is instead installed in a piece of
nonroad equipment subject to the
provisions of this part.
(4) An engine not covered by
paragraphs (1) through (3) of this
definition that is intended to be
installed in new nonroad equipment.
This generally includes installation of
used engines in new equipment. The
engine is no longer new when the
ultimate purchaser receives a title for
the equipment or the product is placed
into service, whichever comes first.
(5) An imported nonroad engine,
subject to the following provisions:
(i) An imported nonroad engine
covered by a certificate of conformity
issued under this part that meets the
criteria of one or more of paragraphs (1)
through (4) of this definition, where the
original engine manufacturer holds the
certificate, is new as defined by those
applicable paragraphs.
(ii) An imported engine covered by a
certificate of conformity issued under
this part, where someone other than the
original engine manufacturer holds the
certificate (such as when the engine is
modified after its initial assembly), is a
new nonroad engine when it is
imported. It is no longer new when the
ultimate purchaser receives a title for
the engine or it is placed into service,
whichever comes first.
(iii) An imported nonroad engine that
is not covered by a certificate of
conformity issued under this part at the
time of importation is new, but only if
it was produced on or after the dates
shown in the following table. This
addresses uncertified engines and
equipment initially placed into service
that someone seeks to import into the
United States. Importation of this kind
of engine (or equipment containing such
an engine) is generally prohibited by 40
CFR part 1068. However, the
importation of such an engine is not
prohibited if the engine has a model
year before 2004, since it is not subject
to standards.
organic compounds measured by the
specified procedure for measuring total
hydrocarbon, expressed as a
hydrocarbon with a hydrogen-to-carbon
mass ratio of 1.85:1.
Total hydrocarbon equivalent has the
meaning given in 40 CFR 1065.1001.
This generally means the sum of the
carbon mass contributions of nonoxygenated hydrocarbons, alcohols and
aldehydes, or other organic compounds
that are measured separately as
contained in a gas sample, expressed as
exhaust hydrocarbon from petroleumfueled engines. The hydrogen-to-carbon
mass ratio of the equivalent
hydrocarbon is 1.85:1.
*
*
*
*
*
Useful life means the period during
which the engine is designed to
properly function in terms of reliability
and fuel consumption, without being
remanufactured, specified as a number
of hours of operation or calendar years,
whichever comes first. It is the period
during which a nonroad engine is
required to comply with all applicable
emission standards. See § 1039.101(g).

(c) Mode caps. Measured NOX
emissions may not exceed the cap
specified in this paragraph (c) for any
applicable duty-cycle test modes with
power greater than 10 percent maximum
engine power. Calculate the mode cap
by multiplying the applicable NOX
standard by 1.5 and rounding to the

this section over their full useful life,
expressed as a period in years or hours
of engine operation, whichever comes
first.
(1) The minimum useful life value is
3 years or 10,000 hours of operation.
(2) Specify a longer useful life in
hours for an engine family under either
of two conditions:
(i) If you design, advertise, or market
your engine to operate longer than the
minimum useful life (your
recommended hours until rebuild
indicates a longer design life).
(ii) If your basic mechanical warranty
is longer than the minimum useful life.

(e) Applicability for testing. The dutycycle emission standards in this section
apply to all testing performed according
to the procedures in § 1042.505,
including certification, production-line,
and in-use testing. See paragraph (g) of
this section for standards that apply for
certain other test procedures, such as
some production-line testing.
(f) Domestic engines. Engines
installed on vessels excluded from 40
CFR part 1043 because they operate
only domestically may not be certified
for use with residual fuels.
(g) Alternate installed-engine
standards. NOX emissions may not
exceed the standard specified in this
paragraph (g) for test of engines
installed on vessels when you are
unable to operate the engine at the test
points for the specified duty cycle, and
you approximate these points consistent
with the specifications of section 6 of
Appendix 8 to the NOX Technical Code.
Calculate the alternate installed-engine
standard by multiplying the applicable
NOX standard by 1.1 and rounding to
the nearest 0.1 g/kW-hr.
144. Section 1042.110 is amended by
revising paragraph (a)(2) and adding
paragraphs (a)(3) and (d) to read as
follows:
§ 1042.110 Recording reductant use and
other diagnostic functions.
(a) * * *
(2) The onboard computer log must
record in nonvolatile computer memory
all incidents of engine operation with
inadequate reductant injection or
reductant quality. Use good engineering
judgment to ensure that the operator can
readily access the information to submit
the report required by § 1042.660. For
example, you may meet this
requirement by documenting the
incident in a text file that can be
downloaded or printed by the operator.
(3) SCR systems on Category 3 engines
must also conform to the provisions of
paragraph (d) of this section if they are
equipped with on-off controls as
allowed under § 1042.115(g).

(d) For Category 3 engines equipped
with on-off controls (as allowed by
§ 1042.115(g)), you must also equip your
engine to continuously monitor NOX
concentrations in the exhaust. Use good
engineering judgment to alert operators
if measured NOX concentrations
indicate malfunctioning emission
controls. Record any such operation in
nonvolatile computer memory. You are
not required to monitor NOX
concentrations during operation for
which the emission controls may be
disabled under § 1042.115(g).
For the purpose of this paragraph (d),
‘‘malfunctioning emission controls’’
means any condition in which the
measured NOX concentration exceeds
the value expected when the engine is
in compliance with the at-sea standard
of § 1042.104(g). Determine these
expected values during production-line
testing of the engine, using linear
interpolation between test points. You
may also use additional intermediate
test points measured during the
production-line test. Note that the
provisions of paragraph (a) of this
section also apply for SCR systems
covered by this paragraph (d). For
engines subject to both the provisions of
paragraph (a) of this section and this
paragraph (d), use good engineering
judgment to integrate diagnostic features
to comply with both paragraphs.
145. Section 1042.115 is amended by
revising paragraphs (d)(2) introductory
text, (f) introductory text, and adding
paragraphs (f)(4) and (g) to read as
follows:

(f) Defeat devices. You may not equip
your engines with a defeat device. A
defeat device is an auxiliary emission
control device that reduces the
effectiveness of emission controls under
conditions that the engine may
reasonably be expected to encounter
during normal operation and use. (Note
that this means emissions control for
operation outside of and between the
official test modes is generally expected
to be similar to the emissions control
demonstrated at the test modes for
engines.) This does not apply to
auxiliary emission control devices you
identify in your certification application
if any of the following is true:
*
*
*
*
*
(4) The engine is a Category 3 engine
and the AECD conforms to the
requirements of paragraph (g) of this
section.
(g) On-off controls for Category 3
engines. Manufacturers may equip
Category 3 engines with features that
disable Tier 3 emission controls subject
to the following provisions:
(1) Features that disable Tier 3
emission controls are considered to be
AECDs whether or not they meet the
definition of an AECD. For example,
manually operated on-off features are
AECDs under this paragraph (g). The
features must be identified in your
application for certification as AECDs.
(2) If IMO has not established an ECA
for U.S. waters, you must demonstrate
that the AECD will not disable emission
controls while operating in areas where
emissions could reasonably be expected
to adversely affect U.S. air quality. If
ECAs have been established for U.S.
waters, then you must demonstrate that
the AECD will not disable emission
control while operating in waters within
the outer boundaries of the ECAs. (Note:
See the regulations in 40 CFR part 1043
for requirements related to operation in
other ECAs.) Compliance with this
paragraph will generally require that the
AECD operation be based on Global
Positioning System (GPS) inputs. We
may consider any relevant information
to determine whether your AECD
conforms to this paragraph (g).
(3) The onboard computer log must
record in nonvolatile computer memory
all incidents of engine operation with
the Tier 3 emission controls disabled.
(4) The engine must comply fully
with the Tier 2 standards when the Tier
3 emission controls are disabled.
146. Section 1042.120 is amended by
adding paragraph (b)(2) and revising
paragraph (c) to read as follows:

(2) For Category 3 engines, your
emission-related warranty must be valid
throughout the engine’s full useful life
as specified in § 1042.104(d).
*
*
*
*
*
(c) Components covered. The
emission-related warranty covers all
components whose failure would
increase an engine’s emissions of any
regulated pollutant, including
components listed in 40 CFR part 1068,
Appendix I, and components from any
other system you develop to control
emissions. The emission-related
warranty for freshly manufactured
marine engines covers these
components even if another company
produces the component. Your
emission-related warranty does not
cover components whose failure would
not increase an engine’s emissions of
any regulated pollutant. For
remanufactured engines, your emissionrelated warranty is required to cover
only those parts that you supply or
those parts for which you specify
allowable part manufacturers. It does
not need to cover used parts that are not
replaced during the remanufacture.
*
*
*
*
*
147. Section 1042.125 is amended by
revising the heading, introductory text,
and paragraphs (a)(1)(iii) and (d) to read
as follows:
§ 1042.125
Maintenance instructions.
Give the ultimate purchaser of each
new engine written instructions for
properly maintaining and using the
engine, including the emission control
system, as described in this section. The
maintenance instructions also apply to
service accumulation on your emissiondata engines as described in § 1042.245
and in 40 CFR part 1065. The
restrictions specified in paragraphs (a)
through (e) of this section related to
allowable maintenance apply only to
Category 1 and Category 2 engines.
Manufacturers may specify any
maintenance for Category 3 engines.
(a) * * *
(1) * * *
(iii) You provide the maintenance free
of charge and clearly say so in your
maintenance instructions.

(d) Noncritical emission-related
maintenance. Subject to the provisions
of this paragraph (d), you may schedule
any amount of emission-related
inspection or maintenance that is not
covered by paragraph (a) of this section
(that is, maintenance that is neither
explicitly identified as critical emissionrelated maintenance, nor that we
approve as critical emission-related
maintenance). Noncritical emission-

related maintenance generally includes
maintenance on the components we
specify in 40 CFR part 1068, Appendix
I that is not covered in paragraph (a) of
this section. You must state in the
owners manual that these steps are not
necessary to keep the emission-related
warranty valid. If operators fail to do
this maintenance, this does not allow
you to disqualify those engines from inuse testing or deny a warranty claim. Do
not take these inspection or
maintenance steps during service
accumulation on your emission-data
engines.
*
*
*
*
*
148. Section 1042.135 is amended by
revising paragraphs (c)(5), (c)(8), (c)(9),
and (c)(11) and adding paragraph (c)(12)
to read as follows:
§ 1042.135
Labeling.
*
*

*
(c) * * *
(5) State the date of manufacture
[DAY (optional), MONTH, and YEAR];
however, you may omit this from the
label if you stamp, engrave, or otherwise
permanently identify it elsewhere on
the engine, in which case you must also
describe in your application for
certification where you will identify the
date on the engine.
*
*
*
*
*
(8) State the useful life for your engine
family if the applicable useful life is
based on the provisions of
§ 1042.101(e)(2) or (3), or
§ 1042.104(d)(2).
(9) Identify the emission control
system. Use terms and abbreviations as
described in 40 CFR 1068.45. You may
omit this information from the label if
there is not enough room for it and you
put it in the owners manual instead.
*
*
*

(11) For a Category 1 or Category 2
engine that can be modified to operate
on residual fuel, but has not been
certified to meet the standards on such
a fuel, include the statement: ‘‘THIS
ENGINE IS CERTIFIED FOR
OPERATION ONLY WITH DIESEL
FUEL. MODIFYING THE ENGINE TO
OPERATE ON RESIDUAL OR
INTERMEDIATE FUEL MAY BE A
VIOLATION OF FEDERAL LAW
SUBJECT TO CIVIL PENALTIES.’’
(12) For an engine equipped with onoff emissions controls as allowed by
§ 1042.115, include the statement:
‘‘THIS ENGINE IS CERTIFIED WITH

revising the heading and introductory
text and adding paragraph (g) to read as
follows:
§ 1042.140 Maximum engine power,
displacement, power density, and maximum
in-use engine speed.
This section describes how to
determine the maximum engine power,
displacement, and power density of an
engine for the purposes of this part.
Note that maximum engine power may
differ from the definition of ‘‘maximum
test power’’ in § 1042.901. This section
also specifies how to determine
maximum in-use engine speed for
Category 3 engines.
*
*
*

(g) Calculate a maximum test speed
for the nominal power curve as
specified in 40 CFR 1065.610. This is
the maximum in-use engine speed used
for calculating the NOX standard in
§ 1042.104 for Category 3 engines.
Alternatively, you may use a lower
value if engine speed will be limited in
actual use to that lower value.
150. Section 1042.145 is amended by

(h) The following interim provisions
apply for Category 3 engines:
(1) Applicability of Tier 3 standards to
Category 3 engines operating in Alaska,
Hawaii, and U.S. Pacific territories. (i)
Category 3 engines are not required to
comply with the Tier 3 NOX standard
when operating in areas of Guam,
American Samoa, or the Commonwealth
of the Northern Mariana Islands.
Category 3 engines are also not required
to comply with the Tier 3 NOX
standards when operating in the waters
of the smallest Hawaiian islands or in
the waters of Alaska west of Kodiak. For
the purpose of this paragraph (h)(1),
‘‘the smallest Hawaiian islands’’
includes all Hawaiian islands other than
Hawaii, Kahoolawe, Kauai, Lanai, Maui,
Molokai, Niihau, and Oahu. Engines
must comply fully with the appropriate
Tier 2 NOX standard and all other
applicable requirements when operating

in the areas identified in this paragraph
(h)(1).
(ii) The provisions of paragraph
(h)(1)(i) of this section do not apply for
areas included in an ECA. The Tier 3
standards apply in full for any area
included in an ECA.
(2) Part 1065 test procedures. You
must generally use the test procedures
specified in subpart F of this part for
Category 3 engines, including the
applicable test procedures in 40 CFR
part 1065. You may use a combination
of the test procedures specified in this
part and the test procedures specified in
40 CFR part 94 before January 1, 2016
without request. After this date, you
must use test procedures only as
specified in subpart F of this part.
Subpart C—[Amended]
151. Section 1042.201 is amended by
revising paragraph (h) to read as
follows:
§ 1042.201 General requirements for
obtaining a certificate of conformity.
*
*
*
*
*
(h) For engines that become new after
being placed into service, such as
engines installed on imported vessels,
we may specify alternate certification
provisions consistent with the intent of
this part. See the definition of ‘‘new
marine engine’’ in § 1042.901.
152. Section 1042.205 is amended by
adding paragraph (b)(12) and revising
paragraphs (i), (o), and (s)(5) to read as
follows:

(o) Present emission data for HC,
NOX, PM, and CO on an emission-data
engine to show your engines meet
emission standards as specified in
§§ 1042.101 or 1042.104. Note that you
must submit PM data for all engines,
whether or not a PM standard applies.
Show emission figures before and after
applying adjustment factors for
regeneration and deterioration factors
for each pollutant and for each engine.
If we specify more than one grade of any

fuel type (for example, high-sulfur and
low-sulfur diesel fuel), you need to
submit test data only for one grade,
unless the regulations of this part
specify otherwise for your engine.
Include emission results for each mode
for Category 3 engines or for other
engines if you do discrete-mode testing
under § 1042.505. Note that §§ 1042.235
and 1042.245 allows you to submit an
application in certain cases without new
emission data.

(5) For Category 2 and Category 3
engines, propose a range of adjustment
for each adjustable parameter, as
described in § 1042.115(d). Include
information showing why the limits,
stops, or other means of inhibiting
adjustment are effective in preventing
adjustment of parameters on in-use
engines to settings outside your
proposed adjustable ranges.

153. Section 1042.220 is revised to
read as follows:
§ 1042.220 Amending maintenance
instructions.
You may amend your emissionrelated maintenance instructions after
you submit your application for
certification as long as the amended
instructions remain consistent with the
provisions of § 1042.125. You must send
the Designated Compliance Officer a
written request to amend your
application for certification for an
engine family if you want to change the
emission-related maintenance
instructions in a way that could affect
emissions. In your request, describe the
proposed changes to the maintenance
instructions. If operators follow the
original maintenance instructions rather
than the newly specified maintenance,
this does not allow you to disqualify
those engines from in-use testing or
deny a warranty claim.
(a) If you are decreasing or
eliminating any specified maintenance,
you may distribute the new
maintenance instructions to your
customers 30 days after we receive your
request, unless we disapprove your
request. This would generally include
replacing one maintenance step with
another. We may approve a shorter time
or waive this requirement.
(b) If your requested change would
not decrease the specified maintenance,
you may distribute the new
maintenance instructions anytime after
you send your request. For example,
this paragraph (b) would cover adding
instructions to increase the frequency of
filter changes for engines in severe-duty
applications.

(c) You need not request approval if
you are making only minor corrections
(such as correcting typographical
mistakes), clarifying your maintenance
instructions, or changing instructions
for maintenance unrelated to emission
control. We may ask you to send us
copies of maintenance instructions
revised under this paragraph (c).

(2) Include engineering evaluations or
data showing that the amended engine
family complies with all applicable
requirements. You may do this by
showing that the original emission-data
engine is still appropriate for showing
that the amended family complies with
all applicable requirements.
*
*
*
*
*
(e) For engine families already
covered by a certificate of conformity,
you may start producing the new or
modified engine configuration anytime
after you send us your amended
application and before we make a
decision under paragraph (d) of this
section. However, if we determine that
the affected engines do not meet
applicable requirements, we will notify
you to cease production of the engines
and may require you to recall the
engines at no expense to the owner.
Choosing to produce engines under this
paragraph (e) is deemed to be consent to
recall all engines that we determine do
not meet applicable emission standards
or other requirements and to remedy the
nonconformity at no expense to the
owner. If you do not provide
information required under paragraph
(c) of this section within 30 days after
we request it, you must stop producing
the new or modified engines.
(f) You may ask us to approve a
change to your FEL in certain cases after
the start of production. The changed
FEL may not apply to engines you have
already introduced into U.S. commerce,
except as described in this paragraph (f).
If we approve a changed FEL after the
start of production, you must include
the new FEL on the emission control
information label for all engines
produced after the change. You may ask
us to approve a change to your FEL in
the following cases:
(1) You may ask to raise your FEL for
your engine family at any time. In your
request, you must show that you will
still be able to meet the emission
standards as specified in subparts B and
H of this part. If you amend your

to include a newly added or modified
engine, as described in paragraph (b)(3)
of this section, use the appropriate FELs
with corresponding production volumes
to calculate emission credits for the
model year, as described in subpart H of
this part. In all other circumstances, you
must use the higher FEL for the entire
family to calculate emission credits
under subpart H of this part.
(2) You may ask to lower the FEL for
your engine family only if you have test
data from production engines showing
that emissions are below the proposed
lower FEL. The lower FEL applies only
to engines you produce after we approve
the new FEL. Use the appropriate FELs
with corresponding production volumes
to calculate emission credits for the
model year, as described in subpart H of
this part.
155. Section 1042.230 is amended by
revising paragraphs (a), (b), (f)
introductory text, and (g) and adding
paragraph (d) to read as follows:
§ 1042.910), except as allowed in
paragraphs (e) and (f) of this section.
*
*
*
*
*
(f) You may group engines that are not
identical with respect to the things
listed in paragraph (b), (c), or (d) of this
section in the same engine family, as
follows:
*
*
*
*
*
(g) If you combine engines that are
subject to different emission standards
into a single engine family under
paragraph (f) of this section, you must
certify the engine family to the more
stringent set of standards for that model
year. For Category 3 engine families that
include a range of maximum in-use
engine speeds, use the highest value of
maximum in-use engine speed to
establish the applicable NOX emission
standard.
156. Section 1042.235 is amended by
revising the introductory text and
paragraphs (a), (c), and (d) introductory
text to read as follows:
§ 1042.230
§ 1042.235 Emission testing required for a
certificate of conformity.
Engine families.
(a) For purposes of certification,
divide your product line into families of
engines that are expected to have
similar emission characteristics
throughout the useful life as described
in this section. You may not group
engines in different engine categories in
the same family. Your engine family is
limited to a single model year.
(b) For Category 1 engines, group
engines in the same engine family if
they are the same in all the following
aspects:
(1) The combustion cycle and the fuel
with which the engine is intended or
designed to be operated.
(2) The cooling system (for example,
raw-water vs. separate-circuit cooling).
(3) Method of air aspiration.
(4) Method of exhaust aftertreatment
(for example, catalytic converter or
particulate trap).
(5) Combustion chamber design.
(6) Nominal bore and stroke.
(7) Cylinder arrangement (for engines
with aftertreatment devices only).
(8) Method of control for engine
operation other than governing (i.e.,
mechanical or electronic).
(9) Application (commercial or
recreational).
(10) Numerical level of the emission
standards that apply to the engine,
except as allowed under paragraphs (f)

This section describes the emission
testing you must perform to show
compliance with the emission standards
in § 1042.101(a) or § 1042.104. See
§ 1042.205(p) regarding emission testing
related to the NTE standards. See
§§ 1042.240 and 1042.245 and 40 CFR
part 1065, subpart E, regarding service
accumulation before emission testing.
See § 1042.655 for special testing
provisions available for Category 3
engines subject to Tier 3 standards.
(a) Select an emission-data engine
from each engine family for testing. For
engines at or above 560 kW, you may
use a development engine that is
equivalent in design to the engine being
certified. For Category 3 engines, you
may use a single-cylinder version of the
engine. Using good engineering
judgment, select the engine
configuration most likely to exceed an
applicable emission standard over the
useful life, considering all exhaust
emission constituents and the range of
installation options available to vessel
manufacturers.
*
*
*
*
*
(c) We may measure emissions from
any of your emission-data engines or
other engines from the engine family, as
follows:
(1) We may decide to do the testing
at your plant or any other facility. If we
do this, you must deliver the engine to
a test facility we designate. The engine
you provide must include appropriate
manifolds, aftertreatment devices,
electronic control units, and other
emission-related components not

normally attached directly to the engine
block. If we do the testing at your plant,
you must schedule it as soon as possible
and make available the instruments,
personnel, and equipment we need.
(2) If we measure emissions from one
of your engines, the results of that
testing become the official emission
results for the engine. Unless we later
invalidate these data, we may decide
not to consider your data in determining
if your engine family meets applicable
requirements.
(3) Before we test one of your engines,
we may set its adjustable parameters to
any point within the specified
adjustable ranges (see § 1042.115(d)).
(4) Before we test one of your engines,
we may calibrate it within normal
production tolerances for anything we
do not consider an adjustable parameter.
For example, this would apply where
we determine that an engine parameter
is not an adjustable parameter (as
defined in § 1042.901) but that it is
subject to production variability.
(d) You may ask to use carryover
emission data from a previous model
year instead of doing new tests, but only
if all the following are true:

157. Section 1042.240 is amended by
revising paragraphs (a), (b), and (c)
introductory text and adding paragraphs
(e) and (f) to read as follows:
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
§ 1042.240 Demonstrating compliance with
exhaust emission standards.
(a) For purposes of certification, your
engine family is considered in
compliance with the emission standards
in § 1042.101(a) or § 1042.104 if all
emission-data engines representing that
family have test results showing
deteriorated emission levels at or below
these standards. This includes all test
points over the course of the durability
demonstration. See paragraph (f) of this
section for provisions related to
demonstrating compliance with nonduty-cycle standards, such as NTE
standards.. Note that your FELs are
considered to be the applicable
emission standards with which you
must comply if you participate in the
ABT program in subpart H of this part.
(b) Your engine family is deemed not
to comply if any emission-data engine
representing that family has test results
showing a deteriorated emission level
for any pollutant that is above an
applicable emission standard. Similarly,
your engine family is deemed not to
comply if any emission-data engine
representing that family has test results
showing any emission level above the
applicable not-to-exceed emission
standard for any pollutant. This

includes all test points over the course
of the durability demonstration.
(c) To compare emission levels from
the emission-data engine with the
applicable emission standards, apply
deterioration factors to the measured
emission levels for each pollutant.
Section 1042.245 specifies how to test
your Category 1 or Category 2 engine to
develop deterioration factors that
represent the deterioration expected in
emissions over your engines’ full useful
life. See paragraph (e) of this section for
determining deterioration factors for
Category 3 engines. Your deterioration
factors must take into account any
available data from in-use testing with
similar engines. Small-volume engine
manufacturers and post-manufacture
marinizers may use assigned
deterioration factors that we establish.
Apply deterioration factors as follows:
*
*
*
*
*
(e) For Category 3 engines, determine
a deterioration factor based on an
engineering analysis. The engineering
analysis must describe how the
measured emission levels from the
emission-data engine show that engines
comply with applicable emission
standards throughout the useful life.
Include this analysis in your application
for certification and add a statement that
all data, analyses, evaluations, and other
information you used are available for
our review upon request.
(f) For NTE standards and mode caps,
use good engineering judgment to
demonstrate compliance based on
testing of low-hour engines. You may,
but are not required to, apply the same
deterioration factors used to show
compliance with the applicable dutycycle standards. We will deny your
application for certification if we
determine that your low-hour test data
show that your engines would exceed
one or more NTE standard or mode cap
during their useful lives.
158. Section 1042.245 is amended by
revising the introductory text and
paragraph (a) to read as follows:
§ 1042.245
Deterioration factors.
This section describes how to
determine deterioration factors for
Category 1 and Category 2 engines,
either with an engineering analysis,
with pre-existing test data, or with new
emission measurements. Apply these
deterioration factors to determine
whether your engines will meet the
duty-cycle emission standards
throughout the useful life as described

testing. Engines certified to a NOx+HC
standard or FEL greater than the Tier 3
NOx+HC standard are considered to rely
on established technology for control of
gaseous emissions, except that this does
not include any engines that use
exhaust-gas recirculation or
aftertreatment. In most cases,
technologies used to meet the Tier 1 and
Tier 2 emission standards would qualify
as established technology. We must

161. Section 1042.301 is amended by
revising paragraphs (a)(2), (c), (e), and (f)
to read as follows:

§ 1042.301
General provisions.
(a) * * *
(2) We may exempt Category 1 engine
families with a projected U.S.-directed
production volume below 100 engines
from routine testing under this subpart.
Request this exemption in your
application for certification and include
your basis for projecting a production
volume below 100 units. We will
approve your request if we agree that
you have made good-faith estimates of
your production volumes. Your
exemption is approved when we grant
your certificate. You must promptly
notify us if your actual production
exceeds 100 units during the model
year. If you exceed the production limit
or if there is evidence of a
nonconformity, we may require you to
test production-line engines under this
subpart, or under 40 CFR part 1068,
subpart E, even if we have approved an
exemption under this paragraph (a)(2).
*
*
*
*
*
(c) Other regulatory provisions
authorize us to suspend, revoke, or void
your certificate of conformity, or order
recalls for engine families, without
regard to whether they have passed
these production-line testing
requirements. The requirements of this
subpart do not affect our ability to do
selective enforcement audits, as
described in 40 CFR part 1068.
Individual engines in families that pass
these production-line testing
requirements must also conform to all
applicable regulations of this part and
40 CFR part 1068.
*
*
*
*
*
(e) If you certify a Category 1 or
Category 2 engine family with carryover
emission data, as described in
§ 1042.235(d), and these equivalent
engine families consistently pass the
production-line testing requirements
over the preceding two-year period, you
may ask for a reduced testing rate for
further production-line testing for that
family. The minimum testing rate is one
engine per engine family. If we reduce
your testing rate, we may limit our
approval to any number of model years.
In determining whether to approve your
request, we may consider the number of
engines that have failed the emission
tests.
(f) We may ask you to make a
reasonable number of production-line
engines available for a reasonable time
so we can test or inspect them for
compliance with the requirements of

this part. For Category 3 engines, you
are not required to deliver engines to us,
but we may inspect and test your
engines at any facility at which they are
assembled or installed in vessels.
162. A new § 1042.302 is added to
subpart D to read as follows:
§ 1042.302 Applicability of this subpart for
Category 3 engines.
If you produce Category 3 engines that
are subject to the requirements of this
part, you must test them as described in
this subpart, except as specified in this
section.
(a) You must test each engine at the
sea trial of the vessel in which it is
installed or within the first 300 hours of
operation, whichever occurs first. Since
you must test each engine, the
provisions of §§ 1042.310 and
1042.315(b) do not apply for Category 3
engines. If we determine that an engine
failure under this subpart is caused by
defective components or design
deficiencies, we may revoke or suspend
your certificate for the engine family as
described in § 1042.340. If we determine
that an engine failure under this subpart
is caused only by incorrect assembly,
we may suspend your certificate for the
engine family as described in
§ 1042.325.
(b) You are only required to measure
NOX emissions. You do not need to
measure HC, CO or PM emissions under
this subpart.
(c) If you are unable to operate the
engine at the test points for the specified
duty cycle, you may approximate these
points consistent with the specifications
of section 6 of Appendix 8 to the NOX
Technical Code and show compliance
with the alternate installed-engine
standard of § 1042.104(g). You must
obtain EPA approval of your test
procedure prior to testing the engine.
Include in your request a description of
your basis for concluding that the
engine cannot be tested at the actual test
points of the specified duty-cycle.
(d) You may measure NOX emissions
at additional test points for the purposes
of the continuous NOX monitoring
requirements of § 1042.110(d). If you do,
you must report these values along with
your other test results. Describe in your
application for certification how you
plan to use these values for continuous
NOX monitoring.
(e) You may ask to measure emissions
according to the Direct Measurement
and Monitoring method specified in
section 6.4 of the NOX Technical Code.
163. Section 1042.305 is amended by
revising paragraphs (a), (d) introductory
text, (d)(2), (e)(2), and (g) to read as

*
(a) Test procedures. Test your
production-line engines using the
applicable testing procedures in subpart
F of this part to show you meet the dutycycle emission standards in subpart B of
this part. For Category 1 and Category 2
engines, the not-to-exceed standards
apply for this testing of Category 1 and
Category 2 engines, but you need not do
additional testing to show that
production-line engines meet the not-toexceed standards. The mode cap
standards apply for the testing of
Category 3 engines.
*
*
*
*
*
(d) Setting adjustable parameters.
Before any test, we may require you to
adjust any adjustable parameter on a
Category 1 engine to any setting within
its physically adjustable range. We may
adjust or require you to adjust any
adjustable parameter on a Category 2 or
Category 3 engine to any setting within
its specified adjustable range.
*
*
*
*
*
(2) We may specify adjustments
within the physically adjustable range
or the specified adjustable range by
considering their effect on emission
levels. We may also consider how likely
it is that someone will make such an
adjustment with in-use engines.
(e) * * *
(2) For Category 2 or Category 3
engines, you may ask us to approve a
Green Engine Factor for each regulated
pollutant for each engine family. Use
the Green Engine Factor to adjust
measured emission levels to establish a
stabilized low-hour emission level.
*
*
*
*
*
(g) Retesting after invalid tests. You
may retest an engine if you determine
an emission test is invalid under
subpart F of this part. Explain in your
written report reasons for invalidating
any test and the emission results from
all tests. If we determine that you
improperly invalidated a test, we may
require you to ask for our approval for
future testing before substituting results
of the new tests for invalid ones.

(a) Calculate your test results as
follows:
(1) Initial and final test results.
Calculate and round the test results for
each engine. If you do several tests on
an engine, calculate the initial results
for each test, then add all the test results
together and divide by the number of
tests. Round this final calculated value
for the final test results on that engine.
Include the Green Engine Factor to
determine low-hour emission results, if
applicable.
(2) Final deteriorated test results.
Apply the deterioration factor for the
engine family to the final test results
(see § 1042.240(c)).
(3) Round deteriorated test results.
Round the results to the number of
decimal places in the emission standard
expressed to one more decimal place.
(b) For Category 1 and Category 2
engines, if a production-line engine fails
to meet emission standards and you test
two additional engines as described in
§ 1042.310, calculate the average
emission level for each pollutant for the
three engines. If the calculated average
emission level for any pollutant exceeds
the applicable emission standard, the
engine family fails the production-line
testing requirements of this subpart. Tell
us within ten working days if this
happens. You may request to amend the
application for certification to raise the
FEL of the engine family as described in
§ 1042.225(f).

detailed description of projected or
actual production figures for an engine
family. We may ask you to divide your
production figures by maximum engine
power, displacement, fuel type, or
assembly plant (if you produce engines
at more than one plant).
(f) Keep records of the engine
identification number for each engine
you produce under each certificate of

approve your request if the failure is not
caused by a defect and it is clear that
you used good engineering judgment in
establishing the original FEL.

(a) Use the equipment and procedures
for compression-ignition engines in 40
CFR part 1065 to determine whether
engines meet the duty-cycle emission
standards in § 1042.101 or 1042.104.
Measure the emissions of all regulated
pollutants as specified in 40 CFR part
1065. Use the applicable duty cycles
specified in § 1042.505.
*

part, except as specified in this section
and § 1042.515.
(1) For service accumulation, use the
test fuel or any commercially available
fuel that is representative of the fuel that
in-use engines will use.
(2) For diesel-fueled engines, use the
appropriate diesel fuel specified in 40
CFR part 1065, subpart H, for emission
testing. Unless we specify otherwise, the
appropriate diesel test fuel for Category
1 and Category 2 engines is the ultra
low-sulfur diesel fuel. If we allow you
to use a test fuel with higher sulfur
levels, identify the test fuel in your
application for certification. Unless we
specify otherwise, the appropriate diesel
test fuel for Category 3 engines is the
high-sulfur diesel fuel. For Category 2
and Category 3 engines, you may ask to
use commercially available diesel fuel
similar but not necessarily identical to
the applicable fuel specified in 40 CFR
part 1065, subpart H; we will approve
your request if you show us that it does
not affect your ability to demonstrate
compliance with the applicable
emission standards.
(3) For Category 1 and Category 2
engines that are expected to use a type
of fuel (or mixed fuel) other than diesel
fuel (such as natural gas, methanol, or
residual fuel), use a commercially
available fuel of that type for emission
testing. If a given engine is designed to
operate on different fuels, we may (at
our discretion) require testing on each
fuel. Propose test fuel specifications that
take into account the engine design and
the properties of commercially available
fuels. Describe these test fuel
specifications in the application for
certification.
*
*
*
*
*
(g) For Category 3 engines, you may
submit test data for NOX, HC, and CO
emissions that were collected as
specified in the Annex VI Technical
Code instead of test data collected as
specified in 40 CFR part 1065. We may
require you to include a brief
engineering analysis showing how these
data demonstrate that your engines
would meet the applicable emission
standards if you had used the test
procedures specified in 40 CFR part
1065.

*
*
*
*
(b) Calculating average adjustment
factors. Calculate the average
adjustment factor (EFA) based on the
following equation: EFA = (F)(EFH) + (1
¥ F)(EFL)
Where:
F = the frequency of the regeneration event
during normal in-use operation, expressed in
terms of the fraction of equivalent tests
during which the regeneration occurs. You
may determine F from in-use operating data
or running replicate tests. For example, if you
observe that the regeneration occurs 125
times during 1000 MW-hrs of operation, and
your engine typically accumulates 1 MW-hr
per test, F would be (125) ÷ (1000) ÷ (1) =
0.125. No further adjustments, including
weighting factors, may be applied to F.
EFH = Measured emissions from a test
segment in which the regeneration occurs.
EFL = Measured emissions from a test
segment in which the regeneration does not
occur.

specify an alternate methodology to
account for regeneration events from
Category 3 engines. If we do not, the
provisions of this section apply as

someone who marinizes a land-based
engine), this section allows you to
introduce new marine engines into U.S.
commerce if they are already certified to
the requirements that apply to
compression-ignition engines under 40
CFR parts 85 and 86 or 40 CFR part 89,
92, 1033, or 1039 for the appropriate
model year. If you comply with all the
provisions of this section, we consider
the certificate issued under 40 CFR part
86, 89, 92, 1033, or 1039 for each engine
to also be a valid certificate of
conformity under this part 1042 for its

after January 1, 2009.
(a) We may grant you an exemption
from the standards and requirements of
this part for a new engine on the
grounds that it is to be used solely for
PO 00000
Frm 00111

competition. The requirements of this
part, other than those in this section, do
not apply to engines that we exempt for
use solely for competition.
(b) We will exempt engines that we
determine will be used solely for
competition. The basis of our
determination is described in
paragraphs (c) and (d) of this section.
Exemptions granted under this section
are good for only one model year and
you must request renewal for each
subsequent model year. We will not
approve your renewal request if we
determine the engine will not be used
solely for competition.
(c) Engines meeting all the following
criteria are considered to be used solely
for competition:
(1) Neither the engine nor any vessels
containing the engine may be displayed
for sale in any public dealership or
otherwise offered for sale to the general
public. Note that this does not preclude
display of these engines as long as they
are not available for sale to the general
public.
(2) Sale of the vessel in which the
engine is installed must be limited to
professional racing teams, professional
racers, or other qualified racers. For
replacement engines, the sale of the
engine itself must be limited to
professional racing teams, professional
racers, other qualified racers, or to the
original vessel manufacturer.
(3) The engine and the vessel in
which it is installed must have
performance characteristics that are
substantially superior to noncompetitive
models.
(4) The engines are intended for use
only as specified in paragraph (e) of this
section.
(d) You may ask us to approve an
exemption for engines not meeting the
criteria listed in paragraph (c) of this
section as long as you have clear and
convincing evidence that the engines
will be used solely for competition.
(e) Engines are considered to be used
solely for competition only if their use
is limited to competition events
sanctioned by the U.S. Coast Guard or
another public organization with
authorizing permits for participating
competitors. Operation of such engines
may include only racing events, trials to
qualify for racing events, and practice
associated with racing events.
Authorized attempts to set speed
records are also considered racing
events. Engines will not be considered
to be used solely for competition if they
are ever used for any recreational or
other noncompetitive purpose. Use of
exempt engines in any recreational
events, such as poker runs and

CFR 1068.101(b)(4).
(f) You must permanently label
engines exempted under this section to
clearly indicate that they are to be used
only for competition. Failure to properly
label an engine will void the exemption
for that engine.
(g) If we request it, you must provide
us any information we need to
determine whether the engines are used
solely for competition. This would
include documentation regarding the
number of engines and the ultimate
purchaser of each engine as well as any
documentation showing a vessel
manufacturer’s request for an exempted
engine. Keep these records for five
years.

179. Section 1042.630 is amended by
revising the introductory text to read as
follows:
This section describes an optional
approach for demonstrating for
certification that catalyst-equipped
engines comply with applicable
emission standards.
(a) Eligibility. You may use the
provisions of this section without our
prior approval to demonstrate that
catalyst-equipped Category 3 engines
meet the Tier 3 standards. In unusual
circumstances, we may also allow you
to use this approach to demonstrate that
catalyst-equipped Category 2 engines
meet the Tier 4 standards. We will
generally approve this for Category 2
engines only if the engines are too large
to be practically tested in a laboratory
with a fully assembled catalyst system.
If we approve this approach for a
Category 2 engine, interpret references
to Tier 3 in this section to mean Tier 4,
and interpret references to Tier 2 in this
section to mean Tier 3.
(b) Required testing. The emissiondata engine must be tested as specified
in Subpart F to verify that the engineout emissions comply with the Tier 2
standards. The catalyst material must be
tested under conditions that accurately
represent actual engine conditions for
the test points. This catalyst testing may
be performed on a benchscale.
(c) Engineering analysis. Include with
your application a detailed engineering
analysis describing how the test data
collected for the engine and catalyst
material demonstrate that all engines in
the family will meet all applicable
emission standards. We may require
that you submit this analysis separately
from your application, or that you
obtain preliminary approval under
§ 1042.210.
§ 1042.630
Personal-use exemption.
This section applies to individuals
who manufacture vessels for personal
use with used engines. If you and your
vessel meet all the conditions of this
section, the vessel and its engine are
considered to be exempt from the
standards and requirements of this part
that apply to new engines and new
vessels. The prohibitions in
§ 1068.101(a)(1) do not apply to engines
exempted under this section. For
example, you may install an engine that
was not certified as a marine engine.

requirements of subpart D of this part.
(e) Other requirements. All other
requirements of this part, including the
non-testing requirements for
certification, apply for these engines.
183. Section 1042.660 is revised to
read as follows:
§ 1042.660 Requirements for vessel
manufacturers, owners, and operators.
(a) For vessels equipped with
emission controls requiring the use of
specific fuels, lubricants, or other fluids,
owners and operators must comply with
the manufacturer/remanufacturer’s
specifications for such fluids when
operating the vessels. Failure to comply
with the requirements of this paragraph
is a violation of 40 CFR 1068.101(b)(1).
For marine vessels containing Category
3 engines that are excluded from the
requirements of 40 CFR part 1043
because they operate only domestically,
it is also a violation of 40 CFR
1068.101(b)(1) to operate the vessel
using residual fuel. Note that 40 CFR
part 80 also includes provisions that
restrict the use of certain fuels by
certain marine engines.
(b) For vessels equipped with SCR
systems requiring the use of urea or
other reductants, owners and operators
must report to us within 30 days any
operation of such vessels without the
appropriate reductant. Failure to
comply with the requirements of this
paragraph is a violation of 40 CFR
1068.101(a)(2). Note that such operation
is a violation of 40 CFR 1068.101(b)(1).
(c) The provisions of this paragraph
(c) apply for marine vessels containing
Category 3 engines.
(1) All maintenance, repair,
adjustment, and alteration of Category 3
engines subject to the provisions of this
part performed by any owner, operator
or other maintenance provider must be
performed using good engineering
judgment, in such a manner that the
engine continues (after the maintenance,
repair, adjustment or alteration) to meet
the emission standards it was certified
as meeting prior to the need for service.
This includes but is not limited to
complying with the maintenance
instructions described in § 1042.125.
Adjustments are limited to the range
specified by the engine manufacturer in
the approved application for
certification.
(2) It is a violation of 40 CFR
1068.101(b)(1) to operate the vessel with
the engine adjusted outside of the
E:\FR\FM\28AUP2.SGM
28AUP2
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
specified adjustable range. Each two
hour period of such operation
constitutes a separate offense. A
violation lasting less than two hours
constitutes a single offense.
(3) The owner and operator of the
engine must maintain on board the
vessel records of all maintenance,
repair, and adjustment that could
reasonably affect the emission
performance of any engine subject to the
provision of this part. Owners and
operators must also maintain, on board
the vessel, records regarding
certification, parameter adjustment, and
fuels used. For engines that are
automatically adjusted electronically,
all adjustments must be logged
automatically. Owners and operators
must make these records available to
EPA upon request. These records must
include the following:
(i) The Technical File, Record Book of
Engine Parameters, and bunker delivery
notes that are required by the Annex VI
Technical Code (incorporated by
reference in § 1042.910). This file must
be transferred to subsequent purchasers
in the event of a sale of the engine or
vessel.
(ii) Specific descriptions of engine
maintenance, repair, adjustment, and
alteration (including rebuilding). The
descriptions must include at least the
date, time, and nature of the
maintenance, repair, adjustment, or
alteration and the position of the vessel
when the maintenance, repair,
adjustment, or alteration was made.
(iii) Emission-related maintenance
instructions provided by the
manufacturer. These instructions must
be transferred to subsequent purchasers
in the event of a sale of the engine or
vessel.
(4) Owners and operators of engines
equipped with on-off emission controls
must comply with the requirements of
this paragraph (c)(4) whenever a
malfunction of the emission controls is
indicated as specified in § 1042.110(d).
You must determine the cause of the
malfunction and remedy it consistent
with paragraph (c)(1) of this section. See
paragraph (b) of this section if the
malfunction is due to either a lack of
reductant or inadequate reductant
quality. If the malfunction occurs during
the useful life, report the malfunction to
the certificate holder for investigation
and compliance with defect reporting
requirements of 40 CFR 1068.501
(unless the malfunction is due to
operation without adequate urea or
other malmaintenance).
(d) For each marine vessel containing
a Category 3 engine, the owner must
annually review the vessel’s records and
submit to EPA a signed statement
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
certifying compliance during the
preceding year with the requirements of
this part that are applicable to owners
and operators of such vessels.
Alternately, if review of the vessel’s
records indicates that there has been
one or more violations of the
requirements of this part, the owner
must submit to EPA a signed statement
specifying the noncompliance,
including the nature of the
noncompliance, the time of the
noncompliance, and any efforts made to
remedy the noncompliance. The
statement of compliance (or
noncompliance) required by this
paragraph must be signed by the
executive with responsibility for marine
activities of the owner. If the vessel is
operated by a different business entity
than the vessel owner, the reporting
requirements of this paragraph (e) apply
to both the owner and the operator.
Compliance with these review and
certification requirements by either the
vessel owner or the vessel operator with
respect to a compliance statement will
be considered compliance with these
requirements by both of these parties for
that compliance statement. The
executive(s) may authorize a captain or
other primary operator to conduct this
review and submit the certification,
provided that the certification statement
is accompanied by written authorization
for that individual to submit such
statements. The Administrator may
waive the requirements of this
paragraph when equivalent assurance of
compliance is otherwise available.
(e) Manufacturers, owners and
operators must allow emission tests and
inspections required by this part to be
conducted and must provide reasonable
assistance to perform such tests or
inspections.
184. A new § 1042.670 is added to
subpart G to read as follows:
§ 1042.670 Special provisions for gas
turbine engines.
The provisions of this section apply

(iii) An imported engine that will be
covered by a certificate of conformity
issued under this part, where someone
other than the original engine
manufacturer holds the certificate (such
as when the engine is modified after its
initial assembly), is a new marine
engine when it is imported. It is no
longer new when the ultimate purchaser
receives a title for the engine or it is
placed into service, whichever comes
first.
(iv) An imported marine engine that
is not covered by a certificate of
conformity issued under this part at the
time of importation is new, but only if
it was produced on or after the dates
shown in the following table. This
addresses uncertified engines and
vessels initially placed into service that
someone seeks to import into the United
States. Importation of this kind of
engine (or vessel containing such an
engine) is generally prohibited by 40
CFR part 1068.

§ 1043.30
General requirements.
(a) Manufacturers, owners and
operators of vessels subject to this part
must comply with Regulations 13, 14,
and 18 of Annex VI and related
provisions of this part. It is the
responsibility of such manufacturers,
owners and operators to ensure that all
employees and other agents operating
on their behalf comply with these
requirements. Manufacturers of engines
subject to this part must comply with all
applicable requirements of Regulation
13 of Annex VI and related provisions
of this part prior to the engine being
installed in the vessel. Note that 33
U.S.C. 1907 also prohibits anyone from
violating any provisions of the MARPOL
Protocol, whether or not they are a
manufacturer, owner or operator.
(b) Engines with power output of
more than 130 kW that are listed in this
paragraph (b) must be covered by a valid
EIAPP certificate unless the engine is
excluded under paragraph (c) of this
section. An EIAPP certificate is valid for
a given engine only if it certifies
compliance with the Tier of standards
applicable to that engine and the vessel
into which it is being installed. Note
that none of the requirements of this
paragraph (b) are limited to new
engines.
(1) Engines meeting any of the
following criteria must be covered by a
valid EIAPP certificate:
(i) Engines installed (or intended to be
installed) on vessels that were
constructed on or after January 1, 2000.
This includes engines that met the
definition of ‘‘new marine engine’’ in 40
CFR 1042.901 at any time on or after
January 1, 2000, unless such engines are
installed on vessels that were
constructed before January 1, 2000.
(ii) Engines that undergo a major
conversion on or after January 1, 2000,
unless the engine have been exempt
from this requirement under paragraph
(e) of this section. See section 2.1 of
Annex VI for a definition of major
conversion.
(2) For such engines intended to be
installed on U.S.-flagged vessels, the
engine may not be introduced into U.S.
commerce before it is covered by a valid
EIAPP certificate, unless it has been
exempted by EPA under 40 CFR part
1042 or part 1068. Uninstalled engines
covered by a valid exemption under 40
CFR part 1042 or part 1068 may be
introduced into U.S. commerce without
PO 00000

a valid EIAPP certificate; however, this
allowance does affect whether the
engine must ultimately be covered by an
EIAPP certificate. For example, engines
allowed to be temporarily distributed in
an uncertified configuration under 40
CFR 1068.260 would not be required to
be covered by an EIAPP certificate while
it is covered by the temporary
exemption under 40 CFR 1068.260;
however, it would be required to be
covered by an EIAPP certificate before
being placed into service. All
uninstalled marine engines within the
United States are presumed to be
intended to be installed on a U.S.flagged vessel, unless there is clear and
convincing evidence to the contrary.
(3) For engines installed on Party
vessels, the engine may not operate in
the U.S. navigable waters or the U.S.
exclusive economic zone, or other
waters designated by the Administrator
under 1902(a)(5) before it is covered by
a valid EIAPP certificate. Engines
installed on non-Party vessels are not
required to have EIAPP certificates,
provided the operator can demonstrate
that the engines conform to the
requirements of Regulation 13 of Annex
VI. Evidence of conformity may be
issued by either the government of a
country that is party to Annex VI or a
recognized classification society. For the
purposes of this paragraph, ‘‘recognized
classification society’’ means a
classification society that is a
participating member of the
International Association of
Classification Societies (IACS).
(c) The following engines are
excluded from the requirement to have
an EIAPP certificate (or equivalent
demonstration of compliance in the case
of non-Party vessels) or otherwise meet
the requirements of Regulation 13 of
Annex VI.
(1) Spark-ignition engines.
(2) Non-reciprocating engines.
(3) Engines that do not use liquid fuel.
(4) Engines intended to be used solely
for emergencies. This includes engines
that power equipment such as pumps
that are intended to be used solely for
emergencies and engines installed in
lifeboats intended to be used solely for
emergencies. It does not include engines
to be used for both emergency and nonemergency purposes.
(d) The requirements specified in
Annex VI apply for vessels subject to
this part for operation in U.S. navigable
waters or the U.S. EEZ. Vessels
operating in waters deemed to be
included in an ECA under this part (see
§ 1043.20) must comply with the
requirements of Annex VI for operation
in an ECA. This means that the
requirements of Regulations 13.5 and
E:\FR\FM\28AUP2.SGM
28AUP2
Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
14.4 of Annex VI apply both in waters
designated by IMO as an ECA and in all
shoreward U.S. waters.
(e) A replacement engine may be
exempted from Regulation 13 of annex
VI by EPA if it is identical to the engine
being replaced and that engine was not
subject to Regulation 13 of Annex VI.
Send requests for such exemptions to
the Designated Certification Officer.
(f) Compliance with the provisions of
this part 1043 does not affect your
responsibilities under 40 CFR part 1042
for engines subject to that part 1042.
§ 1043.40
EIAPP certificates.
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
(a) Engine manufacturers seeking
EIAPP certificates for new engines to be
used in U.S.-flagged vessels must apply
to EPA for an EIAPP certificate in
compliance with the requirements of
this section (which references 40 CFR
part 1042) and the applicable
requirements of Regulation 13 of Annex
VI. Note that only the Administrator or
the EPA official designated by the
Administrator may issue EIAPP
certificates on behalf of the United
States Government.
(b) Persons other than engine
manufacturers may apply for and obtain
EIAPP certificates for new engines to be
used in U.S.-flagged vessels by
complying with the requirements of this
section (which references 40 CFR part
1042) and the applicable requirements
of Regulation 13 of Annex VI.
(c) In appropriate circumstances, EPA
may issue an EIAPP certificate under
this section for non-new engines or
engines for vessels that will not initially
be flagged in the U.S.
(d) The process for obtaining an
EIAPP certificate is described in
§ 1043.41. That section references
regulations in 40 CFR part 1042, which
apply under the Clean Air Act.
References in that part to certificates of
conformity are deemed to mean EIAPP
certificates. References in that part to
the Clean Air Act as the applicable
statute are deemed to mean 33 U.S.C.
1901–1915.
(e) For engines that undergo a major
conversion or for engines installed on
imported vessels that become subject to
the requirements of this part, we may
specify alternate certification provisions
consistent with the intent of this part.
§ 1043.41
EIAPP certification process.
This section describes the process for
obtaining the EIAPP certificate required
by § 1043.40.
(a) You must send the Designated
Certification Officer (see definition in
§ 1043.20) a separate application for an
Engine International Air Pollution
Prevention (EIAPP) certificate for each
VerDate Nov<24>2008

engine family. An EIAPP certificate is
valid starting with the indicated
effective date and is valid for any
production until such time as the design
of the engine family changes or more
stringent emission standards become
applicable, whichever comes first. You
may obtain preliminary approval of
portions of the application consistent
with the provisions of 40 CFR 1042.210.
(b) The application must contain all
the information required by this part. It
must not include false or incomplete
statements or information (see 40 CFR
1042.255). Include the information
specified in 40 CFR 1042.205 except as
follows:
(1) You must include the dates on
which the test engines were built and
the locations where the test engines
were built.
(2) Include a copy of documentation
required by Annex VI related to
maintenance and in-use compliance
(such as the Technical File and onboard
NOX verification procedures as
specified by the NOX Technical Code).
(3) You are not required to provide
information required by 40 CFR
1042.205 about useful life, emission
labels, deterioration factors, PM
emissions, not-to-exceed standards.
(4) You must include a copy of your
warranty instructions, but are not
required to describe how you will meet
warranty obligations.
(c) We may ask you to include less
information than we specify in this
section as long as you maintain all the
information required by paragraph (b) of
this section.
(d) You must use good engineering
judgment for all decisions related to
your application (see 40 CFR 1068.5).
(e) An authorized representative of
your company must approve and sign
the application.
(f) See 40 CFR 1042.255 for provisions
describing how we will process your
application.
(g) Your application, including the
Technical File and onboard NOX
verification procedures, is subject to
amendment as described in 40 CFR
1042.225.
(h) This paragraph (h) describes the
emission testing you must perform.
(1) Select an emission-data engine
from each engine family for testing. For
engines at or above 560 kW, you may
use a development engine that is
equivalent in design to the engine being
certified. For Category 3 engines, you
may use a single-cylinder version of the
engine. Using good engineering
judgment, select the engine
configuration most likely to exceed an
applicable emission standard,
considering all exhaust emission

constituents and the range of
installation options available to vessel
manufacturers.
(2) Test your emission-data engines
using the procedures and equipment
specified in the NOX Technical Code or
subpart F of part 1042. We may require
that your test be witnessed by an EPA
official.
(3) We may measure emissions from
any of your test engines or other engines
from the engine family, as follows:
(i) We may decide to do the testing at
your plant or any other facility. You
must deliver the test engine to any test
facility we designate. The test engine
you provide must include appropriate
manifolds, aftertreatment devices,
electronic control units, and other
emission-related components not
normally attached directly to the engine
block. If we do the testing at your plant,
you must schedule it as soon as possible
and make available the instruments,
personnel, and equipment we need.
(ii) If we measure emissions from one
of your test engines, the results of that
testing become the official emission
results for the engine. Unless we later
invalidate these data, we may decide
not to consider your data in determining
if your engine family meets applicable
requirements.
(iii) Before we test one of your
engines, we may set its adjustable
parameters to any point within the
specified adjustable ranges (see 40 CFR
1042.115(d)).
(iv) Before we test one of your
engines, we may calibrate it within
normal production tolerances for
anything we do not consider an
adjustable parameter.
(4) We may require you to test a
second engine of the same or different
configuration in addition to the engine
tested under paragraph (b) of this
section.
(5) If you use an alternate test
procedure under 40 CFR 1065.10 and
later testing shows that such testing
does not produce results that are

§ 1043.80 Recordkeeping and reporting
requirements for fuel suppliers.
If you supply any fuel for an engine
on any vessel identified in paragraph (a)
of this section, you must comply with
the requirements of Regulation 18 of
Annex VI to provide bunker delivery
notes to the vessel operators and to keep
copies for your records.
(a) The requirements of this section
apply for fuel delivered to any of the
following vessels:
(1) Vessels of 400 gross tonnage and
above.
(2) Platforms and drilling rigs.
(b) Except as allowed by paragraph (c)
of this section, the bunker delivery note
must contain the following:
(1) The name and IMO number of
receiving vessel.
(2) Port (or other description of the
location, if the delivery does not take
place at a port).
(3) Date the fuel is delivered to the
vessel (or date on which the delivery
begins where the delivery begins on one
day and ends on a later day).
(4) Name, address, and telephone
number of fuel supplier.
(5) Fuel type and designation under
40 CFR part 80.
(6) Quantity in metric tons.

on which it is to be used. For example,
with respect to conformity to Regulation
14 of Annex VI, a fuel designated and
intended for use in an ECA any time
between July 1, 2010 and January 1 2015
may not have a sulfur content above
1.00 weight percent.
(c) Measure density and sulfur
content according to the specifications
of Annex VI, or other methods we
approve as equivalent. Where the
density and/or sulfur content of the
delivered fuel cannot be measured, we
may allow the use of alternate methods
to specify the density and/or sulfur
content of the fuel. For example, where
fuel is supplied from multiple tanks on
a supply vessel, we may allow the
density and sulfur content of the fuel to
be calculated as a weighted average of
the measured densities and sulfur
contents of the fuel that is supplied
from each tank.

(b) Averaging, banking, and trading.
You may generate or use emission
credits under the averaging, banking,
and trading (ABT) program described in
subpart H of this part for demonstrating
compliance with HC+NOX emission
standards. For CO emissions, you may
generate or use emission credits for
averaging as described in subpart H of
this part, but such credits may not be
banked or traded. To generate or use
emission credits, you must specify a
family emission limit for each pollutant
you include in the ABT program for
each engine family. These family
emission limits serve as the emission
standards for the engine family with
respect to all required testing instead of
the standards specified in this section.
An engine family meets emission
standards even if its family emission
limit is higher than the standard, as long
as you show that the whole averaging
set of applicable engine families meets
the emission standards using emission

(c) Special maintenance. You may
specify more frequent maintenance to
address problems related to special
situations, such as atypical engine
operation. You must clearly state that
this additional maintenance is
associated with the special situation you
are addressing. We may disapprove your
maintenance instructions if we
determine that you have specified
special maintenance steps to address
engine operation that is not atypical, or
that the maintenance is unlikely to
occur in use. If we determine that
certain maintenance items do not
qualify as special maintenance under

§ 1048.240 How do I demonstrate that my
engine family complies with exhaust
emission standards?
(a) For purposes of certification, your
engine family is considered in
compliance with the applicable
numerical emission standards in
§ 1048.101(a) and (b) if all emission-data
engines representing that family have
test results showing deteriorated
emission levels at or below these
standards. This includes all test points
over the course of the durability
demonstration. See paragraph (e) of this
section for provisions related to
demonstrating compliance with fieldtesting standards.
(b) Your engine family is deemed not
to comply if any emission-data engine
representing that family has test results
showing a deteriorated emission level
for any pollutant that is above an
applicable emission standard from
§ 1048.101(a) and (b). Similarly, your
engine family is deemed not to comply
if any emission-data engine representing
that family has test results showing any
emission level above the applicable
field-testing standard for any pollutant.
This includes all test points over the
course of the durability demonstration.

(2) Other all-terrain vehicles have
three or more wheels and one or more
seats, are designed for operation over
rough terrain, are intended primarily for
transportation, and have a maximum
vehicle speed higher than 25 miles per
hour . Golf carts generally do not meet
these criteria since they are generally
not designed for operation over rough
terrain.

Offroad utility vehicle means a
nonroad vehicle that has four or more
wheels, seating for two or more persons,
is designed for operation over rough
terrain, and has either a rear payload
capacity of 350 pounds or more or
seating for six or more passengers.
Vehicles intended primarily for
recreational purposes that are not
capable of transporting six passengers
(such as dune buggies) are not offroad
utility vehicles. (Note: § 1051.1(a)
specifies that some offroad utility
vehicles are required to meet the
requirements that apply for all-terrain
vehicles.) Unless there is significant
information to the contrary, we consider
vehicles to be intended primarily for
recreational purposes if they are
marketed for recreational use, have a
rear payload capacity no greater than
1,000 pounds, and meet at least five of
the following criteria:
(1) Front and rear suspension travel is
greater than 18 cm.
(2) The vehicle has no tilt bed.
(3) The vehicle has no mechanical
power take-off (PTO) and no
permanently installed hydraulic system
for operating utility-oriented accessory
devices.
(4) The engine has in-use operating
speeds at or above 4,000 rpm.
(5) Maximum vehicle speed is greater
than 35 miles per hour.
(6) The speed at which the engine
produces peak power is above 4,5000
rpm and the engine is equivalent to
engines in ATVs that you have certified.
For the purpose of this paragraph (6),
the engine is considered equivalent if it
could be included in the same emission
family based on the characteristics
specified in § 1051.230(b).
(7) Gross Vehicle Weight Rating is no
greater than 3,750 pounds. This is the

(c) The provisions of 40 CFR 1068.215
apply for cases in which the
manufacturer takes possession of
engines for purposes of recovering
components as described in this
paragraph (c). Note that this paragraph
(c) does not apply for certified engines
that still have the emission control
information label since such engines do
not need an exemption.
(1) You must label the engine as
specified in 40 CFR 1068.215(c)(3),
except that the label may be removable
as specified in 40 CFR 1068.45(b).
(2) You may not resell the engine. For
components other than the engine
block, you may generate revenue from
the sale of the components that you
recover, or from the sale of new engines
containing these components. You may
also use components other than the
engine block for engine rebuilds as
otherwise allowed under the
regulations. You may use the engine
block from an engine that is exempted
under this paragraph (c) only to make a
new engine, and then only where such
an engine has a separate identity from
the original engine.
(3) Once the engine has reached its
final destination, you may stop
collecting records describing the
engine’s final disposition and how you
use the engine. This does not affect the
requirement to maintain the records you
have already collected under 40 CFR

displacement in 2013, the appropriate
bond amount is $750,000. Adjust the
value of the bond as follows:
(1) If your estimated or actual U.S.directed production volume in any later
year increases beyond the level
appropriate for your current bond
payment, you must post additional bond
to reflect the increased volume within
90 days after you change your estimate
or determine the actual production
volume. You may not decrease your
bond.
(2) If you sell engines without
aftertreatment components under the

cumulative weight loss represented by
yi and cumulative time represented by
yref. The daily measurements must be at
approximately the same time each day.
You may omit up to two daily
measurements in any seven-day period.
Test for ten full days, then determine
when to stop testing as follows:
(i) You may stop testing after the
measurement on the tenth day if r2 is at
or above 0.95 or if the measured value
is less than 50 percent of the applicable
standard. (Note that if a Family
Emission Limit applies for the family, it
is considered to be the applicable
standard for that family.) This means
that if you stop testing with an r2 below
0.95, you may not use the data to show
compliance with a Family Emission
Limit less than twice the measured
value.
(ii) If after ten days of testing your r2
value is below 0.95 and your measured
value is more than 50 percent of the
applicable standard, continue testing for
a total of 20 days or until r2 is at or
above 0.95. If r2 is not at or above 0.95
within 20 days of testing, discontinue
the test and precondition the fuel tank
further until it has stabilized emission
levels, then repeat the testing.

253. Section 1060.801 is amended by

definitions for ‘‘Installed marine fuel
line’’ and ‘‘Portable marine fuel line’’ to
read as follows:
§ 1060.801
part?
What definitions apply to this
*
*
*
*
*
Detachable fuel line means a fuel line
or fuel line assembly intended to be
used with a portable nonroad fuel tank
and which is connected by special
fittings to the fuel tank and/or engine for
easy disassembly. Fuel lines that require
a wrench or other tools to disconnect
are not considered detachable fuel lines.
Fuel lines that are labeled or marketed
as USCG Type B1 fuel line as specified
in 33 CFR 183.540 are not considered
detachable fuel lines if they are sold to
the ultimate purchaser without quickconnect fittings or similar hardware.
*
*
*
*
*
Installed marine fuel line means a fuel
line designed for delivering fuel to a
Marine SI engine, excluding portable
marine fuel line.
*
*
*
*
*
Portable marine fuel line means a
detachable fuel line that is used or
intended to be used to supply fuel to a
marine engine during operation. This
also includes any fuel line labeled or
marketed at USCG Type B1 fuel line as
specified in 33 CFR 183.540, whether or
not it includes detachable connecting
hardware; this is often called universal
fuel line.
*
*
*
*
*
Sealed means lacking openings to the
atmosphere that would allow a
measurable amount of liquid or vapor to
leak out under normal operating
pressures or other pressures specified in
this part. For example, you may
generally establish a maximum value for
operating pressures based on the highest
pressure you would observe from an
installed fuel tank during continuous
equipment operation on a sunny day
with ambient temperatures of 35°C. A
fuel system may be considered to have
E:\FR\FM\28AUP2.SGM
28AUP2
Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
no measurable leak if it does not release
bubbles when held underwater at the
identified pressure for 60 seconds. This
determination presumes the use of good
engineering judgment; for example, it
would not be appropriate to test the fuel
tank such that small leaks would avoid
detection by collecting in a cavity
created by holding the tank with a
certain orientation. Sealed fuel systems
may have openings for emission
controls or for fuel lines needed to route
fuel to the engine.

For example, this may apply if your
engine cannot operate on the specified
duty cycle. In this case, tell us in
writing why you cannot satisfactorily
test your engine using this part’s
procedures and ask to use a different
approach. We will approve your request
if we determine that it would produce
emission measurements that represent
in-use operation and we determine that
it can be used to show compliance with
the requirements of the standard-setting
part. Where we approve special
procedures that differ substantially from
the specified procedures, we may
preclude you from participating in
averaging, banking, and trading with the
affected engine families.

the allowed procedures. The following
provisions apply to requests for
alternate procedures:
(i) Applications. Follow the
instructions in § 1065.12.
(ii) Submission. Submit requests in
writing to the Designated Compliance
Officer.
(iii) Notification. We may approve
your request by telling you directly, or
we may issue guidance announcing our

*
*

*
*
(c) We generally set brake-specific
emission standards over test intervals
and/or duty cycles, as follows:
(1) Engine operation. Testing may
involve measuring emissions and work
in a laboratory-type environment or in
the field, as described in paragraph (f)
of this section. For most laboratory
PO 00000
Frm 00129
Fmt 4701
Sfmt 4702
44569
testing, the engine is operated over one
or more duty cycles specified in the
standard-setting part. However,
laboratory testing may also include nonduty cycle testing (such as simulation of
field testing in a laboratory). For field
testing, the engine is operated under
normal in-use operation. The standardsetting part specifies how test intervals
are defined for field testing. Refer to the
definitions of ‘‘duty cycle’’ and ‘‘test
interval’’ in § 1065.1001. Note that a
single duty cycle may have multiple test
intervals and require weighting of
results from multiple test intervals to
calculate a composite brake-specific
emissions value to compare to the
standard.
(2) Constituent determination.
Determine the total mass of each
constituent over a test interval by
selecting from the following methods:
(i) Continuous sampling. In
continuous sampling, measure the
constituent’s concentration
continuously from raw or dilute
exhaust. Multiply this concentration by
the continuous (raw or dilute) flow rate
at the emission sampling location to
determine the constituent’s flow rate.
Sum the constituent’s flow rate
continuously over the test interval. This
sum is the total mass of the emitted
constituent.
(ii) Batch sampling. In batch
sampling, continuously extract and
store a sample of raw or dilute exhaust
for later measurement. Extract a sample
proportional to the raw or dilute
exhaust flow rate. You may extract and
store a proportional sample of exhaust
in an appropriate container, such as a
bag, and then measure HC, CO, and NOX
concentrations in the container after the
test interval. You may deposit PM from
proportionally extracted exhaust onto
an appropriate substrate, such as a filter.
In this case, divide the PM by the
amount of filtered exhaust to calculate
the PM concentration. Multiply batch
sampled concentrations by the total
(raw or dilute) flow from which it was
extracted during the test interval. This
product is the total mass of the emitted
constituent.
(iii) Combined sampling. You may use
continuous and batch sampling
simultaneously during a test interval, as
follows:
(A) You may use continuous sampling
for some constituents and batch
sampling for others.
(B) You may use continuous and
batch sampling for a single constituent,
with one being a redundant
measurement. See § 1065.201 for more
information on redundant
measurements.

Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
(3) Work determination. Determine
work over a test interval by one of the
following methods:
(i) Speed and torque. Synchronously
multiply speed and brake torque to
calculate instantaneous values for
engine brake power. Sum engine brake
power over a test interval to determine
total work.
(ii) Fuel consumed and brake-specific
fuel consumption. Directly measure fuel
consumed or calculate it with chemical
balances of the fuel, intake air, and
exhaust. To calculate fuel consumed by
a chemical balance, you must also
measure either intake-air flow rate or
exhaust flow rate. Divide the fuel
consumed during a test interval by the
brake-specific fuel consumption to
determine work over the test interval.
For laboratory testing, calculate the
brake-specific fuel consumption using
fuel consumed and speed and torque
over a test interval. For field testing,
refer to the standard-setting part and
§ 1065.915 for selecting an appropriate
value for brake-specific fuel
consumption.

*
*
*
*
*
(e) This paragraph (e) includes
provisions for simulating charge-air
cooling in the laboratory. This approach
is described in paragraph (e)(1) of this
section. Limits on using this approach
are described in paragraphs (e)(2) and
(3) of this section.
(1) Use a charge-air cooling system
with a total intake-air capacity that
represents production engines’ in-use
installation. Design any laboratory
charge-air cooling system to minimize
accumulation of condensate. Drain any
accumulated condensate and
completely close all drains before
starting a duty cycle. Keep the drains
closed during the emission test.
Maintain coolant conditions as follows:
(i) Maintain a coolant temperature of
at least 20 °C at the inlet to the chargeair cooler throughout testing. We
recommend maintaining a coolant
temperature of 25 ± 5 °C at the inlet of
the charge-air cooler.
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
(ii) At the engine conditions specified
by the manufacturer, set the coolant
flow rate to achieve an air temperature
within ±5 °C of the value specified by
the manufacturer after the charge-air
cooler’s outlet. Measure the air-outlet
temperature at the location specified by
the manufacturer. Use this coolant flow
rate set point throughout testing. If the
engine manufacturer does not specify
engine conditions or the corresponding
charge-air cooler air outlet temperature,
set the coolant flow rate at maximum
engine power to achieve a charge-air
cooler air outlet temperature that
represents in-use operation.
(iii) If the engine manufacturer
specifies pressure-drop limits across the
charge-air cooling system, ensure that
the pressure drop across the charge-air
cooling system at engine conditions
specified by the manufacturer is within
the manufacturer’s specified limit(s).
Measure the pressure drop at the
manufacturer’s specified locations.
(2) Using a constant flow rate as
described in paragraph (e)(1) of this
section may result in unrepresentative
overcooling of the intake air. The
provisions of this paragraph (e)(2) apply
instead of the provisions of
§ 1065.10(c)(1) for this simulation. Our
allowance to cool intake air as specified
in this paragraph (e) does not affect your
liability for field testing or for laboratory
testing that is done in a way that better
represents in-use operation. Where we
determine that this allowance adversely
affects your ability to demonstrate that
your engines would comply with
emission standards under in-use
conditions, we may require you to use
more sophisticated setpoints and
controls of charge-air pressure drop,
coolant temperature, and flow rate to
achieve more representative results.
(3) This approach does not apply for
field testing. You may not correct
measured emission levels from field
testing to account for any differences
caused by the simulated cooling in the
laboratory.
260. Section 1065.140 is amended by
revising paragraphs (c)(6), (e)
introductory text, and (e)(4) to read as
follows:
§ 1065.140 Dilution for gaseous and PM
constituents.
*
*
*
*
*
(c) * * *
(6) Aqueous condensation. To ensure
that you measure a flow that
corresponds to a measured
concentration, you may either prevent
aqueous condensation throughout the
dilution tunnel or you may allow
aqueous condensation to occur and then
measure humidity at the flow meter
PO 00000
Frm 00130
Fmt 4701
Sfmt 4702
inlet. You may heat or insulate the
dilution tunnel walls, as well as the
bulk stream tubing downstream of the
tunnel to prevent aqueous
condensation. Calculations in
§ 1065.645 and § 1065.650 account for
either method of addressing humidity in
the diluted exhaust. Note that
preventing aqueous condensation
involves more than keeping pure water
in a vapor phase (see § 1065.1001).
*
*
*
*
*
(e) Dilution air temperature, dilution
ratio, residence time, and temperature
control of PM samples. Dilute PM
samples at least once upstream of
transfer lines. You may dilute PM
samples upstream of a transfer line
using full-flow dilution, or partial-flow
dilution immediately downstream of a
PM probe. In the case of partial-flow
dilution, you may have up to 26 cm of
insulated length between the end of the
probe and the dilution stage, but we
recommend that the length be as short
as practical. The intent of these
specifications is to minimize heat
transfer to or from the emission sample
before the final stage of dilution, other
than the heat you may need to add to
prevent aqueous condensation. This is
accomplished by initially cooling the
sample through dilution. Configure
dilution systems as follows:
*
*
*
*
*
(4) Control sample temperature to a
(47 ±5) °C tolerance, as measured
anywhere within 20 cm upstream or
downstream of the PM storage media
(such as a filter). Measure this
temperature with a bare-wire junction
thermocouple with wires that are (0.500
±0.025) mm diameter, or with another
suitable instrument that has equivalent
performance.
261. Section 1065.145 is revised to
read as follows:
§ 1065.145 Gaseous and PM probes,
transfer lines, and sampling system
components.
(a) Continuous and batch sampling.
Determine the total mass of each
constituent with continuous or batch
sampling, as described in
§ 1065.15(c)(2). Both types of sampling
systems have probes, transfer lines, and
other sampling system components that
are described in this section.
(b) Options for engines with multiple
exhaust stacks. Measure emissions from
a test engine as described in this
paragraph (b) if it has multiple exhaust
stacks. You may choose to use different
measurement procedures for different
pollutants under this paragraph (b) for
a given test. For purposes of this part
1065, the test engine includes all the
devices related to converting the
E:\FR\FM\28AUP2.SGM

mstockstill on DSKH9S0YB1PROD with PROPOSALS2
Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
chemical energy in the fuel to the
engine’s mechanical output energy. This
may or may not involve vehicle- or
equipment-based devices. For example,
all of an engine’s cylinders are
considered to be part of the test engine
even if the exhaust is divided into
separate exhaust stacks. As another
example, all the cylinders of a dieselelectric locomotive are considered to be
part of the test engine even if they
transmit power through separate output
shafts, such as might occur with
multiple engine-generator sets working
in tandem. Use one of the following
procedures to measure emissions with
multiple exhaust stacks:
(1) Route the exhaust flow from the
multiple stacks into a single flow as
described in § 1065.130(c)(6). Sample
and measure emissions after the exhaust
streams are mixed. Calculate the
emissions as a single sample from the
entire engine. We recommend this as
the preferred option, since it requires
only a single measurement and
calculation of the exhaust molar flow for
the entire engine.
(2) Sample and measure emissions
from each stack and calculate emissions
separately for each stack. Add the mass
(or mass rate) emissions from each stack
to calculate the emissions from the
entire engine. Testing under this
paragraph (b)(2) requires measuring or
calculating the exhaust molar flow for
each stack separately. If the exhaust
molar flow in each stack cannot be
calculated from combustion air flow(s),
fuel flow(s), and measured gaseous
emissions, and it is impractical to
measure the exhaust molar flows
directly, you may alternatively
proportion the engine’s calculated total
exhaust molar flow rate (where the flow
is calculated using combustion air mass
flow(s), fuel mass flow(s), and emissions
concentrations) based on exhaust molar
flow measurements in each stack using
a less accurate, non-traceable method.
For example, you may use a total
pressure probe and static pressure
measurement in each stack.
(3) Sample and measure emissions
from one stack and repeat the duty cycle
as needed to collect emissions from
each stack separately. Calculate the
emissions from each stack and add the
separate measurements to calculate the
mass (or mass rate) emissions from the
entire engine. Testing under this
paragraph (b)(3) requires measuring or
calculating the exhaust molar flow for
each stack separately. You may
alternatively proportion the engine’s
calculated total exhaust molar flow rate
based on calculation and measurement
limitations as described in paragraph
(b)(2) of this section. Use the average of
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
the engine’s total power or work values
from the multiple test runs to calculate
brake-specific emissions. Divide the
total mass (or mass rate) of each
emission by the average power (or
work). You may alternatively use the
engine power or work associated with
the corresponding stack during each test
run if these values can be determined
for each stack separately.
(4) Sample and measure emissions
from each stack separately and calculate
emissions for the entire engine based on
the stack with the highest concentration.
Testing under this paragraph (b)(4)
requires only a single exhaust flow
measurement or calculation for the
entire engine. You may determine
which stack has the highest
concentration by performing multiple
test runs, reviewing the results of earlier
tests, or using good engineering
judgment. Note that the highest
concentration of different pollutants
may occur in different stacks. Note also
that the stack with the highest
concentration of a pollutant during a
test interval for field testing may be a
different stack than the one you
identified based on average
concentrations over a duty cycle.
(5) Sample emissions from each stack
separately and combine the wet sample
streams from each stack proportionally
to the exhaust molar flows in each stack.
Measure the emission concentrations
and calculate the emissions for the
entire engine based on these weighted
concentrations. Testing under this
paragraph (b)(5) requires measuring or
calculating the exhaust molar flow for
each stack separately during the test run
to proportion the sample streams from
each stack. If it is impractical to
measure the exhaust molar flows
directly, you may alternatively
proportion the wet sample streams
based on less accurate, non-traceable
flow methods. For example, you may
use a total pressure probe and static
pressure measurement in each stack.
The following restrictions apply for
testing under this paragraph (b)(5):
(i) You must use an accurate,
traceable measurement or calculation of
the engine’s total exhaust molar flow
rate for calculating the mass of
emissions from the entire engine.
(ii) You may dry the single, combined,
proportional sample stream; you may
not dry the sample streams from each
stack separately.
(iii) You must measure and
proportion the sample flows from each
stack with active flow controls. For PM
sampling, you must measure and
proportion the diluted sample flows
from each stack with active flow
controls that use only smooth walls

Fmt 4701

with no sudden change in crosssectional area. For example, you may
control the dilute exhaust PM sample
flows using electrically conductive
vinyl tubing and a control device that
pinches the tube over a long enough
transition length so no flow separation
occurs.
(iv) For PM sampling, the transfer
lines from each stack must be joined so
the angle of the joining flows is 12.5° or
less. Note that the exhaust manifold
must meet the same specifications as the
transfer line according to paragraph (d)
of this section.
(6) Sample emissions from each stack
separately and combine the wet sample
streams from each stack equally.
Measure the emission concentrations
and calculate the emissions for the
entire engine based on these measured
concentrations. Testing under this
paragraph (b)(6) assumes that the rawexhaust and sample flows are the same
for each stack. The following
restrictions apply for testing under this
paragraph (b)(6):
(i) You must measure and
demonstrate that the sample flow from
each stack is within 5% of the value
from the stack with the highest sample
flow. You may alternatively ensure that
the stacks have equal flow rates without
measuring sample flows by designing a
passive sampling system that meets the
following requirements:
(A) The probes and transfer line
branches must be symmetrical, have
equal lengths and diameters, have the
same number of bends, and have no
filters.
(B) If probes are designed such that
they are sensitive to stack velocity, the
stack velocity must be similar at each
probe. For example, a static pressure
probe used for gaseous sampling is not
sensitive to stack velocity.
(C) The stack static pressure must be
the same at each probe. You can meet
this requirement by placing probes at
the end of stacks that are vented to
atmosphere.
(D) For PM sampling, the transfer
lines from each stack must be joined so
the angle of the joining flows is 12.5° or
less. Note that the exhaust manifold
must meet the same specifications as the
transfer line according to paragraph (d)
of this section.
(ii) You may use the procedure in this
paragraph (b)(6) only if you perform an
analysis showing that the resulting error
due to imbalanced stack flows and
concentrations is either at or below 2%.
You may alternatively show that the
resulting error does not impact your
ability to demonstrate compliance with
applicable standards. For example, you
may use less accurate, non-traceable

measurements of emission
concentrations and molar flow in each
stack and demonstrate that the
imbalances in flows and concentrations
cause 2% or less error.
(iii) For a two-stack engine, you may
use the procedure in this paragraph
(b)(6) only if you can show that the
stack with the higher flow has the lower
average concentration for each pollutant
over the duty cycle.
(iv) You must use an accurate,
traceable measurement or calculation of
the engine’s total exhaust molar flow
rate for calculating the mass of
emissions from the entire engine.
(v) You may dry the single, equally
combined, sample stream; you may not
dry the sample streams from each stack
separately.
(vi) You may determine your exhaust
flow rates with a chemical balance of
exhaust gas concentrations and either
intake air flow or fuel flow.
(c) Gaseous and PM sample probes. A
probe is the first fitting in a sampling
system. It protrudes into a raw or
diluted exhaust stream to extract a
sample, such that its inside and outside
surfaces are in contact with the exhaust.
A sample is transported out of a probe
into a transfer line, as described in
paragraph (d) of this section. The
following provisions apply to sample
probes:
(1) Probe design and construction.
Use sample probes with inside surfaces
of 300 series stainless steel or, for raw
exhaust sampling, use any nonreactive
material capable of withstanding raw
exhaust temperatures. Locate sample
probes where constituents are mixed to
their mean sample concentration. Take
into account the mixing of any
crankcase emissions that may be routed
into the raw exhaust. Locate each probe
to minimize interference with the flow
to other probes. We recommend that all
probes remain free from influences of
boundary layers, wakes, and eddies—
especially near the outlet of a rawexhaust tailpipe where unintended
dilution might occur. Make sure that
purging or back-flushing of a probe does
not influence another probe during
testing. You may use a single probe to
extract a sample of more than one
constituent as long as the probe meets
all the specifications for each
constituent.
(2) Gaseous sample probes. Use either
single-port or multi-port probes for
sampling gaseous emissions. You may
orient these probes in any direction
relative to the raw or diluted exhaust
flow. For some probes, you must control
sample temperatures, as follows:
(i) For probes that extract NOx from
diluted exhaust, control the probe’s wall
VerDate Nov<24>2008
01:07 Aug 28, 2009
Jkt 217001
temperature to prevent aqueous
condensation.
(ii) For probes that extract
hydrocarbons for THC or NMHC
analysis from the diluted exhaust of
compression-ignition engines, 2-stroke
spark-ignition engines, or 4-stroke
spark-ignition engines below 19 kW, we
recommend heating the probe to
minimize hydrocarbon contamination
consistent with good engineering
judgment. If you routinely fail the
contamination check in the 1065.520
pretest check, we recommend heating
the probe section to approximately 190
°C to minimize contamination.
(3) PM sample probes. Use PM probes
with a single opening at the end. Orient
PM probes to face directly upstream. If
you shield a PM probe’s opening with
a PM pre-classifier such as a hat, you
may not use the preclassifier we specify
in paragraph (f)(1) of this section. We
recommend sizing the inside diameter
of PM probes to approximate isokinetic
sampling at the expected mean flow
rate.
(d) Transfer lines. You may use
transfer lines to transport an extracted
sample from a probe to an analyzer,
storage medium, or dilution system,
noting certain restrictions for PM
sampling in § 1065.140(e). Minimize the
length of all transfer lines by locating
analyzers, storage media, and dilution
systems as close to probes as practical.
We recommend that you minimize the
number of bends in transfer lines and
that you maximize the radius of any
unavoidable bend. Avoid using 90
°elbows, tees, and cross-fittings in
transfer lines. Where such connections
and fittings are necessary, take steps,
using good engineering judgment, to
ensure that you meet the temperature
tolerances in this paragraph (d). This
may involve measuring temperature at
various locations within transfer lines
and fittings. You may use a single
transfer line to transport a sample of
more than one constituent, as long as
the transfer line meets all the
specifications for each constituent. The
following construction and temperature
tolerances apply to transfer lines:
(1) Gaseous samples. Use transfer
lines with inside surfaces of 300 series
stainless steel, PTFE, VitonTM, or any
other material that you demonstrate has
better properties for emission sampling.
For raw exhaust sampling, use a nonreactive material capable of
withstanding raw exhaust temperatures.
You may use in-line filters if they do not
react with exhaust constituents and if
the filter and its housing meet the same
temperature requirements as the transfer
lines, as follows:
PO 00000
Frm 00132
Fmt 4701
Sfmt 4702
(i) For NOX transfer lines upstream of
either an NO2-to-NO converter that
meets the specifications of § 1065.378 or
a chiller that meets the specifications of
§ 1065.376, maintain a sample
temperature that prevents aqueous
condensation.
(ii) For THC transfer lines for testing
compression-ignition engines, 2-stroke
spark-ignition engines, or 4-stroke
spark-ignition engines below 19 kW,
maintain a wall temperature tolerance
throughout the entire line of (191 ± 11)
°C. If you sample from raw exhaust, you
may connect an unheated, insulated
transfer line directly to a probe. Design
the length and insulation of the transfer
line to cool the highest expected raw
exhaust temperature to no lower than
191 °C, as measured at the transfer line’s
outlet. For dilute sampling, you may use
a transition zone between the probe and
transfer line of up to 92 cm to allow
your wall temperature to transition to
(191 ± 11) °C.
(2) PM samples. We recommend
heated transfer lines or a heated
enclosure to minimize temperature
differences between transfer lines and
exhaust constituents. Use transfer lines
that are inert with respect to PM and are
electrically conductive on the inside
surfaces. We recommend using PM
transfer lines made of 300 series
stainless steel. Electrically ground the
inside surface of PM transfer lines.
(e) Optional sample-conditioning
components for gaseous sampling. You
may use the following sampleconditioning components to prepare
gaseous samples for analysis, as long as
you do not install or use them in a way
that adversely affects your ability to
show that your engines comply with all
applicable gaseous emission standards.
(1) NO2-to-NO converter. You may use
an NO2-to-NO converter that meets the
efficiency-performance check specified
in § 1065.378 at any point upstream of
a NOx analyzer, sample bag, or other
storage medium.
(2) Sample dryer. You may use either
type of sample dryer described in this
paragraph (e)(2) to decrease the effects
of water on gaseous emission
measurements. You may not use a
chemical dryer, or use dryers upstream
of PM sample filters.
(i) Osmotic-membrane. You may use
an osmotic-membrane dryer upstream of
any gaseous analyzer or storage
medium, as long as it meets the
temperature specifications in paragraph
(d)(1) of this section. Because osmoticmembrane dryers may deteriorate after
prolonged exposure to certain exhaust
constituents, consult with the
membrane manufacturer regarding your
application before incorporating an
E:\FR\FM\28AUP2.SGM
28AUP2
mstockstill on DSKH9S0YB1PROD with PROPOSALS2
Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
osmotic-membrane dryer. Monitor the
dewpoint, Tdew, and absolute pressure,
ptotal, downstream of an osmoticmembrane dryer. You may use
continuously recorded values of Tdew
and ptotal in the amount of water
calculations specified in § 1065.645. If
you do not continuously record these
values, you may use their peak values
observed during a test or their alarm
setpoints as constant values in the
calculations specified in § 1065.645.
You may also use a nominal ptotal, which
you may estimate as the dryer’s lowest
absolute pressure expected during
testing.
(ii) Thermal chiller. You may use a
thermal chiller upstream of some gas
analyzers and storage media. You may
not use a thermal chiller upstream of a
THC measurement system for
compression-ignition engines, 2-stroke
spark-ignition engines, or 4-stroke
spark-ignition engines below 19 kW. If
you use a thermal chiller upstream of an
NO2-to-NO converter or in a sampling
system without an NO2-to-NO converter,
the chiller must meet the NO2 lossperformance check specified in
§ 1065.376. Monitor the dewpoint, Tdew,
and absolute pressure, ptotal, downstream
of a thermal chiller. You may use
continuously recorded values of Tdew
and ptotal in the emission calculations
specified in § 1065.650. If you do not
continuously record these values, you
may use the maximum temperature and
minimum pressure values observed
during a test or the high alarm
temperature setpoint and the low alarm
pressure setpoint as constant values in
the amount of water calculations
specified in § 1065.645. You may also
use a nominal ptotal, which you may
estimate as the dryer’s lowest absolute
pressure expected during testing. If it is
valid to assume the degree of saturation
in the thermal chiller, you may calculate
Tdew based on the known chiller
performance and continuous monitoring
of chiller temperature, Tchiller. If you do
not continuously record values of Tchiller,
you may use its peak value observed
during a test, or its alarm setpoint, as a
constant value to determine a constant
amount of water according to
§ 1065.645. If it is valid to assume that
Tchiller is equal to Tdew, you may use
Tchiller in lieu of Tdew according to
§ 1065.645. If it is valid to assume a
constant temperature offset between
Tchiller and Tdew, due to a known and
fixed amount of sample reheat between
the chiller outlet and the temperature
measurement location, you may factor
in this assumed temperature offset value
into emission calculations. If we ask for
it, you must show by engineering
analysis or by data the validity of any
assumptions allowed by this paragraph
(e)(2)(ii).
(3) Sample pumps. You may use
sample pumps upstream of an analyzer
or storage medium for any gas. Use
sample pumps with inside surfaces of
300 series stainless steel, PTFE, or any
other material that you demonstrate has
better properties for emission sampling.
For some sample pumps, you must
control temperatures, as follows:
(i) If you use a NOx sample pump
upstream of either an NO2-to-NO
converter that meets § 1065.378 or a
chiller that meets § 1065.376, it must be
heated to prevent aqueous
condensation.
(ii) For testing compression-ignition
engines, 2-stroke spark-ignition engines,
or 4-stroke spark-ignition engines below
19 kW, if you use a THC sample pump
upstream of a THC analyzer or storage
medium, its inner surfaces must be
heated to a tolerance of (191 ±11) °C.
(4) Ammonia Scrubber. You may use
ammonia scrubbers for any or all
gaseous sampling systems to prevent
interference with NH3, poisoning of the
NO2-to-NO converter, and deposits in
the sampling system or analyzers.
Follow the ammonia scrubber
manufacturer’s recommendations or use
good engineering judgment in applying
ammonia scrubbers.
(f) Optional sample-conditioning
components for PM sampling. You may
use the following sample-conditioning
components to prepare PM samples for
analysis, as long as you do not install or
use them in a way that adversely affects
your ability to show that your engines
comply with the applicable PM
emission standards. You may condition
PM samples to minimize positive and
negative biases to PM results, as follows:
(1) PM preclassifier. You may use a
PM preclassifier to remove largediameter particles. The PM preclassifier
may be either an inertial impactor or a
cyclonic separator. It must be
constructed of 300 series stainless steel.
The preclassifier must be rated to
remove at least 50% of PM at an
44573
aerodynamic diameter of 10 μm and no
more than 1% of PM at an aerodynamic
diameter of 1 μm over the range of flow
rates for which you use it. Follow the
preclassifier manufacturer’s instructions
for any periodic servicing that may be
necessary to prevent a buildup of PM.
Install the preclassifier in the dilution
system downstream of the last dilution
stage. Configure the preclassifier outlet
with a means of bypassing any PM
sample media so the preclassifier flow
may be stabilized before starting a test.
Locate PM sample media within 75 cm
downstream of the preclassifier’s exit.
You may not use this preclassifier if you
use a PM probe that already has a
preclassifier. For example, if you use a
hat-shaped preclassifier that is located
immediately upstream of the probe in
such a way that it forces the sample
flow to change direction before entering
the probe, you may not use any other
preclassifier in your PM sampling
system.
(2) Other components. You may
request to use other PM conditioning
components upstream of a PM
preclassifier, such as components that
condition humidity or remove gaseousphase hydrocarbons from the diluted
exhaust stream. You may use such
components only if we approve them
under § 1065.10.

Linearity verification.

(6) For all measured quantities, use
instrument manufacturer
recommendations and good engineering
judgment to select reference values, yrefi,
that cover a range of values that you
expect would prevent extrapolation
beyond these values during emission
testing. We recommend selecting a zero
reference signal as one of the reference
values of the linearity verification. For
stand-alone pressure, temperature, and

recommend at least three reference
values. For all other linearity
verifications select at least ten reference
values.

paragraph (c) of this section. Use
reference values that simulate actual
values, or introduce an actual value and
measure it with a referencemeasurement system. In the latter case,
the reference value is the value reported
by the reference-measurement system.
Reference values and referencemeasurement systems must be NISTtraceable. We recommend using
calibration reference quantities that are
NIST-traceable within 0.5% uncertainty,
if not specified otherwise in other
sections of this part 1065. Use the
following recommended methods to
generate reference values or use good
engineering judgment to select a
different reference:
(1) Speed. Run the engine or
dynamometer at a series of steady-state
speeds and use a strobe, a photo
tachometer, or a laser tachometer to
record reference speeds.
(2) Torque. Use a series of calibration
weights and a calibration lever arm to
simulate engine torque. You may
instead use the engine or dynamometer

the reference load cell measurement as
the reference value. Refer to § 1065.310
for a torque-calibration procedure
similar to the linearity verification in

(3) Electrical power. Use a controlled

binary or multi-gas span gases. You may

blending span gases diluted in N2 with
span gases diluted in air. You may use

analyzers at the same time. In designing
your experimental setup, avoid pressure
pulsations due to stopping the flow
through the gas blending device. If H2O
correction is applicable, then span gases
must be humidified before entering the
analyzer; however, you may not
humidify NO2 span gas by passing it
through a sealed humidification vessel
that contains water. You must humidify
NO2 span gas with another moist gas
stream. We recommend humidifying
your NO–CO–CO2–C3H8–CH4, balance
N2 blended gas by flowing the gas
mixture through a sealed vessel that
humidifies the gas by bubbling it
through distilled water and then mixing
the gas with dry NO2 gas, balance
purified synthetic air. If your system
does not use a sample dryer to remove
water from the sample gas, you must
humidify your span gas to the highest
sample H2O content that you estimate
during emission sampling. If your
system uses a sample dryer during
testing, it must pass the sample dryer
verification check in § 1065.342, and
you must humidify your span gas to an
H2O content greater than or equal to the
level determined in § 1065.145(e)(2). If
you are humidifying span gases without
NO2, use good engineering judgment to
ensure that the wall temperatures in the
transfer lines, fittings, and valves from
the humidifying system to the probe are
above the dewpoint required for the
target H2O content. If you are
humidifying span gases with NO2, use
good engineering judgment to ensure
that there is no condensation in the
transfer lines, fittings, or valves from the
point where humidified gas is mixed
with NO2 span gas to the probe. We
recommend that you design your setup
so that the wall temperatures in the
transfer lines, fittings, and valves from
the humidifying system to the probe are
at least 5 °C above the local sample gas
dewpoint. Operate the measurement
and sample handling system as you do
for emission testing. Make no
modifications to the sample handling
system to reduce the risk of
condensation. Flow humidified gas
through the sampling system before this
check to allow stabilization of the
measurement system’s sampling
handling system to occur, as it would
for an emission test.

(4) Maintain the sample lines, fittings,
and valves from the location where the
humidified gas water content is
measured to the inlet of the sampling
system at a temperature at least 5 °C
above the local humidified gas
dewpoint. For dryers used in NOX
sample systems, verify the sample
system components used in this
verification to prevent aqueous
condensation as required in
§ 1065.145(d)(1)(i). We recommend that
the sample system components be
maintained at least 5 °C above the local
humidified gas dewpoint to prevent
aqueous condensation.

(7) The sample dryer meets the
verification if the dewpoint at the
sample dryer pressure as measured in
paragraph (d)(6) of this section is less
than the dewpoint corresponding to the
sample dryer specifications as
determined in § 1065.145(e)(2) plus 2 °C

interference verification as follows:
(1) Start, operate, zero, and span the
CO2 NDIR analyzer as you would before
an emission test. If the sample is passed
through a dryer during emission testing,
PO 00000

you may run this verification test with
the dryer if it meets the requirements of
§ 1065.342. Operate the dryer at the
same conditions as you will for an
emission test. You may also run this
verification test without the sample
dryer.
(2) Create a humidified test gas by
bubbling zero gas that meets the
specifications in § 1065.750 through
distilled water in a sealed vessel. If the
sample is not passed through a dryer
during emission testing, control the
vessel temperature to generate an H2O
level at least as high as the maximum
expected during emission testing. If the
sample is passed through a dryer during
emission testing, control the vessel
temperature to generate an H2O level at
least as high as the level determined in
§ 1065.145(e)(2) for that dryer.
(3) Introduce the humidified test gas
into the sample system. You may
introduce it downstream of any sample
dryer, if one is used during testing.
(4) If the sample is not passed through
a dryer during this verification test,
measure the water mole fraction, xH2O,
of the humidified test gas, as close as
possible to the inlet of the analyzer. For
example, measure dewpoint, Tdew, and
absolute pressure, ptotal, to calculate
xH2O. Verify that the water content meets
the requirement in paragraph (d)(2) of
this section. If the sample is passed
through a dryer during this verification
test, you must verify that the water
content of the humidified test gas
downstream of the vessel meets the
requirement in paragraph (d)(2) of this
section based on either direct
measurement of the water content (e.g.,
dewpoint and pressure) or an estimate
based on the vessel pressure and
temperature. Use good engineering
judgment to estimate the water content.
For example, you may use previous
direct measurements of water content to
verify the vessel’s level of saturation.
(5) If a sample dryer is not used in this
verification test, use good engineering
judgment to prevent condensation in the
transfer lines, fittings, or valves from the
point where xH2O is measured to the
analyzer. We recommend that you
design your system so the wall
temperatures in the transfer lines,
fittings, and valves from the point where
xH2O is measured to the analyzer are at
least 5 °C above the local sample gas
dewpoint.

(1) Start, operate, zero, and span the
CO NDIR analyzer as you would before
an emission test. If the sample is passed
through a dryer during emission testing,
you may run this verification test with
the dryer if it meets the requirements of

(2) Create a humidified CO2 test gas
by bubbling a CO2 span gas that meets
the specifications in § 1065.750 through
distilled water in a sealed vessel. If the
sample is not passed through a dryer
during emission testing, control the
vessel temperature to generate an H2O
level at least as high as the maximum
expected during emission testing. If the
sample is passed through a dryer during
emission testing, control the vessel
temperature to generate an H2O level at
least as high as the level determined in

CO2 span gas concentration at least as
high as the maximum expected during
testing.
(3) Introduce the humidified CO2 test
gas into the sample system. You may
introduce it downstream of any sample

(5) Humidify the NO span gas by

control the vessel temperature to
generate an H2O level approximately
equal to the maximum mole fraction of
H2O expected during emission testing. If
the humidified NO span gas sample
does not pass through a sample dryer,
the quench verification calculations in
§ 1065.675 scale the measured H2O
quench to the highest mole fraction of
H2O expected during emission testing. If
the humidified NO span gas sample
passes through a dryer for this
verification test, control the vessel
temperature to generate an H2O level at
least as high as the level determined in
§ 1065.145(e)(2). For this case, the

(i) Discrete-mode cycles. Before
emission sampling, stabilize an engine

speed and torque values are constant.
Record mean values for that mode, and
then stabilize the engine at the next
mode. Continue to sample each mode
discretely as separate test intervals and
calculate weighted emission results
according to the standard-setting part.
(ii) Ramped-modal cycles. Perform
ramped-modal cycles similar to the way
you would perform transient cycles,
except that ramped-modal cycles
involve mostly steady-state engine
operation. Generate a ramped-modal
duty cycle as a sequence of second-bysecond (1 Hz) reference speed and

(5) Perform one of the following:
(i) For any engine subject only to
steady-state duty cycles (i.e., discretemode or ramped-modal), you may
perform an engine map by using
discrete speeds. Select at least 20 evenly
spaced setpoints between warm idle
speed and the endpoint. At each
setpoint, stabilize speed and allow
torque to stabilize. Record the mean
speed and torque at each setpoint. We
recommend that you stabilize an engine
for at least 15 seconds at each setpoint
and record the mean feedback speed
and torque of the last (4 to 6) seconds.
Use linear interpolation to determine
intermediate speeds and torques. Use
this series of speeds and torques to
generate the power map as described in
paragraph (e) of this section.
(ii) For any variable-speed engine, you
may perform an engine map by using a
continuous sweep of speed by
continuing to record the mean feedback
speed and torque at 1 Hz or more
frequently and increasing speed at a
constant rate such that it takes (4 to 6)
min to sweep from 95% of warm idle
speed to the endpoint. Stop recording
after you complete the sweep. From the
series of mean speed and maximum
torque values, use linear interpolation to
determine intermediate values. Use this
series of speeds and torques to generate
the power map as described in
paragraph (e) of this section.
(iii) Determine the endpoint of the
map using one of the following
methods:
(A) You may use as your endpoint the
highest speed above maximum power at
which (50±5) % of maximum power
occurs.
(B) You may use as your endpoint any
speed higher than that specified in
paragraph (b)(5)(iii)(A) of this section. If
you determine your endpoint for a
continuous sweep according to this
paragraph (b)(5)(iii)(B), you may base
your compliance with the (4 to 6) min
specification in paragraph (b)(5)(ii) of
this section on the time it takes you to

reach the speed specified in paragraph
(b)(5)(iii)(A) of this section.
(C) If the speed specified in paragraph
(b)(5)(iii)(A) of this section is unsafe
(e.g, for ungoverned engines), use good
engineering judgment to map up to the
maximum safe speed. If the engine is
equipped with a governor that prevents
the engine from operating at the speeds
specified in paragraph (b)(5)(iii)(A) of
this section, you may use the highest
achievable speed as the endpoint. Note
that under § 1065.10(c)(1) we may allow
you to disregard portions of the map
when selecting maximum test speed if
the specified procedure would result in
a duty cycle that does not represent inuse operation.

continuous measurements for discrete
mode steady-state duty cycles.
Determine the minimum primary and
minimum overall dilution ratios using
one of the following methods (you may
use a different method for each stage of
dilution):
(a) Determine minimum dilution ratio
based on molar flow data. This involves
determination of at least two of the
following three quantities: raw exhaust
flow (or previously diluted flow),
dilution air flow, and dilute exhaust
flow. You may determine the raw
exhaust flow rate based on the measured
intake air molar flow rate and the
chemical balance terms in § 1065.655.
You may alternatively estimate the
molar raw exhaust flow rate based on
intake air, fuel rate measurements, and
fuel properties, consistent with good
engineering judgment.
(b) Determine minimum dilution ratio
based on tracer gas (e.g., CO2)
concentrations in the raw (or previously
diluted) and dilute exhaust corrected for
any removed water.
(c) Use good engineering judgment to
develop your own method of
determining dilution ratios.

(b) Drift validation and drift
correction. Calculate two sets of brakespecific emission results for each test
interval. Calculate one set using the data
before drift correction and calculate the
other set after correcting all the data for
drift according to § 1065.672. Use the
two sets of brake-specific emission
results to validate the duty cycle for
drift as follows:
(1) The duty cycle is validated for
drift if you satisfy one of the following
criteria:
(i) For each test interval of the duty
cycle and for each regulated pollutant,
the difference between the uncorrected
and the corrected brake-specific
emission values over the test interval is
within ±4% of the uncorrected value or
applicable emission standard,
whichever is greater.
(ii) For the entire duty cycle and for
each regulated pollutant, the difference
between the uncorrected and corrected
composite brake-specific emission
values over the entire duty cycle is
within ±4% of the uncorrected value or
the applicable emission standard,
whichever is greater. Note that for
purposes of drift validation using
composite brake-specific emission
values over the entire duty cycle, leave
unaltered any negative emission results
PO 00000
Frm 00139
Fmt 4701
Sfmt 4702
44579
over a given test interval (i.e., do not set
them to zero). A third calculation of
composite brake-specific emission
values is required for final reporting.
This calculation uses drift-corrected
mass (or mass rate) values from each test
interval and sets any negative mass (or
mass rate) values to zero before
calculating the composite brake-specific
emission values over the entire duty
cycle.
(2) For standards consisting of
multiple emission mass measurements
(such as NMHC+NOX or separate NO
and NO2 measurements to comply with
a NOX standard), the duty cycle shall be
validated for drift if you satisfy one of
the following:
(i) For each test interval of the duty
cycle and for each individual mass, the
difference between the uncorrected and
the corrected brake-specific emission
values over the test interval is within
±4% of the uncorrected value; or
(ii) For the entire duty cycle the
difference between the combined (e.g.
NMHC + NOX) uncorrected and
combined (e.g. NMHC + NOX) corrected
composite brake-specific emissions
values over the entire duty cycle is
within ±4% of the uncorrected value or
the applicable emissions standard,
whichever is greater.
(3) If the test is not validated for drift,
you may consider the test results for the
duty cycle to be valid only if, using
good engineering judgment, the
observed drift does not affect your
ability to demonstrate compliance with
the applicable emission standards. For
example, if the drift-corrected value is
less than the standard by at least two
times the absolute difference between
the uncorrected and corrected values,
you may consider the data to be valid
for demonstrating compliance with the
applicable standard.

that weights and sums the results of
individual test intervals in a duty cycle.

rectangular integration, where each
indexed value (i.e., ‘‘i’’) represents (or

interval, delta-t. You may also integrate
continuous signals using trapezoidal

(3) For field testing, you may calculate
the ratio of total mass to total work,
where these individual values are
determined as described in paragraph (f)
of this section. You may also use this
approach for laboratory testing,
consistent with good engineering
judgment. Good engineering judgment
dictates that this method not be used if
there are any work flow paths described
in § 1065.210 that cross the system
boundary, other than the primary output
shaft (crankshaft). This is a special case
in which you use a signal linearly
proportional to raw exhaust molar flow
rate to determine a value proportional to
total emissions. You then use the same
linearly proportional signal to
determine total work using a chemical
balance of fuel, intake air, and exhaust
as described in § 1065.655, plus
information about your engine’s brakespecific fuel consumption. Under this
method, flow meters need not meet
accuracy specifications, but they must
meet the applicable linearity and
repeatability specifications in subpart D
or subpart J of this part. The result is a
brake-specific emission value calculated
as follows:

(2) To calculate an engine’s mean
steady-state total power, P, add the
mean steady-state power from all the
work paths described in § 1065.210 that
cross the system boundary including
electrical power, mechanical shaft
power, and fluid pumping power. For
all work paths, except the engine’s
primary output shaft (crankshaft), the
mean steady-state power over the test
interval is the integration of the net
work flow rate (power) out of the system
boundary divided by the period of the
test interval. When power flows into the
system boundary, the power/work flow
rate signal becomes negative; in this
case, include these negative power/work
rate values in the integration to
calculate the mean power from that
work path. Some work paths may result
in a negative mean power. Include
negative mean power values from any
work path in the mean total power from

by its respective flow. For all systems,

paragraphs (c)(2) through (4) of this
section that is appropriate for your
system. Calculate the total mass of
emissions as follows:
*
*
*
*
*
(d) Total work over a test interval. To
calculate the total work from the engine
over a test interval, add the total work
from all the work paths described in
§ 1065.210 that cross the system
boundary including electrical energy/
work, mechanical shaft work, and fluid
pumping work. For all work paths,
except the engine’s primary output shaft
(crankshaft), the total work for the path
over the test interval is the integration
of the net work flow rate (power) out of
the system boundary. When energy/
work flows into the system boundary,
this work flow rate signal becomes
negative; in this case, include these
negative work rate values in the
integration to calculate total work from
that work path. Some work paths may
result in a negative total work. Include
negative total work values from any
work path in the calculated total work
from the engine rather than setting the
values to zero. The rest of this paragraph
(d) describes how to calculate total work
from the engine’s primary output shaft
over a test interval. Before integrating
power on the engine’s primary output
shaft, adjust the speed and torque data
for the time alignment used in
§ 1065.514(c). Any advance or delay
used on the feedback signals for cycle
validation must also be used for
calculating work. Account for work of
accessories according to § 1065.110.
Exclude any work during cranking and
starting. Exclude work during actual
motoring operation (negative feedback
torques), unless the engine was
connected to one or more energy storage
devices. Examples of such energy
storage devices include hybrid
powertrain batteries and hydraulic
accumulators, like the ones illustrated
in Figure 1 of § 1065.210. Exclude any
work during reference zero-load idle
periods (0% speed or idle speed with 0
N.m reference torque). Note, that there
must be two consecutive reference zero
load idle points to establish a period
where this applies. Include work during
idle points with simulated minimum

following equation:

the engine rather than setting these
values to zero. The rest of this paragraph
(e)(2) describes how to calculate the
mean power from the engine’s primary
output shaft. Calculate using Equation
1065.650–13, noting that P, fn and T
refer to mean power, mean rotational
shaft frequency, and mean torque from
the primary output shaft. Account for
the power of simulated accessories
according to § 1065.110 (reducing the
mean primary output shaft power or
torque by the accessory power or
torque). Set the power to zero during
actual motoring operation (negative
feedback torques), unless the engine was
connected to one or more energy storage
devices. Examples of such energy
storage devices include hybrid
powertrain batteries and hydraulic
accumulators, like the ones illustrated
in Figure 1 of § 1065.210. Set the power
to zero for modes with a zero reference
load (0 N·m reference torque or 0 kW
reference power). Include power during
idle modes with simulated minimum
torque or power.

(g) Brake-specific emissions over a
duty cycle with multiple test intervals.
The standard-setting part may specify a
duty cycle with multiple test intervals,
such as with discrete-mode steady-state
testing. Unless we specify otherwise,
calculate composite brake-specific
emissions over the duty cycle as
described in this paragraph (g). If a
measured mass (or mass rate) is
negative, set it to zero for calculating
composite brake-specific emissions, but
leave it unchanged for drift validation.
In the case of calculating composite
brake-specific emissions relative to a
combined emission standard (such as a
NOX + NMHC standard), change any
negative mass (or mass rate) values to
zero for a particular pollutant before
combining the values for the different
pollutants.

combustion air humidity and dilution
air humidity in the chemical balance; as
long as your combustion air and
dilution air humidities remain within
tolerances of ±0.0025 mol/mol of their
respective mean values over the test
interval. For each emission
concentration, x, and amount of water,
xH2Oexh, you must determine their
completely dry concentrations, xdry and
xH2Oexhdry. You must also use your fuel’s
atomic hydrogen-to-carbon ratio, α,
oxygen-to-carbon ratio, β, sulfur-tocarbon ratio, γ, and nitrogen-to-carbon
ratio, δ. You may measure α, β, γ, and

Duty cycle means one of the

Duty cycles are specified in the

cycle may consist of one or more test
intervals. A series of speed and torque
values meeting the definition of this
paragraph (1) may also be considered a
test cycle. For example, a duty cycle
may be a ramped-modal cycle, which
has one test interval; a cold-start plus
hot-start transient cycle, which has two
test intervals; or a discrete-mode cycle,
which has one test interval for each
mode.
(2) A set of weighting factors and the
corresponding speed and torque values,
where the weighting factors are used to

Percent (%) means a representation of
exactly 0.01 (with infinite precision).
Significant digits for the product of %
and another value, or the expression of
any other value as a percentage, are
defined as follows:
(1) Where we specify some percentage

significant digits as the total value. The
specified percentage by which the total
value is multiplied has infinite
precision. Note that not all displayed or
recorded digits are significant. For
example, 2% of a span value where the
span value is 101.3302 is 2.026604.
However, where the span value has
limited precision such that only one
digit to the right of the decimal is
significant (i.e., the actual value is
101.3), 2% of the span value is 2.026.

expressions of CO2 concentrations),
determine the number of significant
digits using the same method as you
would use for determining the number
of significant digits of any calculated
value. For example, a calculated value
of 0.0321, where the last three digits are
significant, is equivalent to 3.21%.

*
*
Engine means an engine block with an
installed crankshaft, or a gas turbine
engine. The term engine does not
include engine blocks without an
installed crankshaft, nor does it include
any assembly of reciprocating engine
components that does not include the
engine block. (Note: For purposes of this
definition, any component that is the
primary means of converting an engine’s
energy into usable work is considered a
crankshaft, whether or not it is known
commercially as a crankshaft.) This

includes complete and partially
complete engines as follows:
*
*
*
*
*
Gas turbine engine means anything
commercially known as a gas turbine
engine or any collection of assembled
engine components that is substantially
similar to engines commercially known
as gas turbine engines. For example, a
jet engine is a gas turbine engine. Gas
turbine engines may be complete or
partially complete. Turbines that rely on
external combustion such as steam
engines are not gas turbine engines.

Ultimate purchaser means the first
person who in good faith purchases a
new engine or new piece of equipment
for purposes other than resale.

described in paragraph (e) of this
section is a violation of § 1068.101(a)(1)
unless the engine complies with all the
requirements of this chapter for new
stationary engines of the same type (for
example, a compression-ignition engine
rated at 40 kW) and model year. For a
new stationary engine that is required to
be certified under 40 CFR part 60, the
engine must have been certified to be
compliant with all the requirements that
apply to new stationary engines of the
same type and model year, and must be
in its certified configuration. Note that
the definitions of ‘‘model year’’ in the
standard-setting part generally identifies
the engine’s original date of
manufacture as the basis for
determining which standards apply if it
becomes a stationary engine after it is no
longer new. For example, see 40 CFR
60.4219 and 60.4248.

specify otherwise, where we require
engine/equipment labels that may be
removable, you may instead label the
packaging if the engines/equipment are
packaged together as described in this
paragraph (c). For example, this may
involve packaging engines together by
attaching them to a rack, binding them
together on a pallet, or enclosing them
in a box. The provisions of this
paragraph (c) also apply for engines/
equipment boxed individually where
you do not apply labels directly to the

§ 1068.101 What general actions does this
regulation prohibit?
This section specifies actions that are
prohibited and the maximum civil
penalties that we can assess for each
violation in accordance with 42 U.S.C.
7522 and 7524. The maximum penalty
values listed in paragraphs (a) and (b) of
this section apply as of January 12,
2009. As described in paragraph (h) of
this section, these maximum penalty
limits are different for earlier violations
and they may be adjusted as set forth in
40 CFR part 19.
(a) The following prohibitions and
requirements apply to manufacturers of
new engines, manufacturers of
equipment containing these engines,
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
and manufacturers of new equipment,
except as described in subparts C and D
of this part:
(1) Introduction into commerce. You
may not sell, offer for sale, or introduce
or deliver into commerce in the United
States or import into the United States
any new engine/equipment after
emission standards take effect for the
engine/equipment, unless it is covered
by a valid certificate of conformity for
its model year and has the required
label or tag. You also may not take any
of the actions listed in the previous
sentence with respect to any equipment
containing an engine subject to this
part’s provisions unless the engine is
covered by a valid certificate of
conformity for its model year and has
the required engine label or tag. We may
assess a civil penalty up to $37,500 for
each engine or piece of equipment in
violation.
(i) For purposes of this paragraph
(a)(1), a valid certificate of conformity is
one that applies for the same model year
as the model year of the equipment
(except as allowed by § 1068.105(a)),
covers the appropriate category of
engines/equipment (such as locomotive
or Marine SI), and conforms to all
requirements specified for equipment in
the standard-setting part. Engines/
equipment are considered not covered
by a certificate unless they are in a
configuration described in the
application for certification.
(ii) The requirements of this
paragraph (a)(1) also cover new engines
you produce to replace an older engine
in a piece of equipment, unless the
engine qualifies for the replacementengine exemption in § 1068.240.
(iii) For engines used in equipment
subject to equipment-based standards,
you may not sell, offer for sale, or
introduce or deliver into commerce in
the United States or import into the
United States any new engine unless it
is covered by a valid certificate of
conformity for its model year and has
the required label or tag. See the
standard-setting part for more
information about how this prohibition
applies.
(2) Reporting and recordkeeping. This
chapter requires you to record certain
types of information to show that you
meet our standards. You must comply
with these requirements to make and
maintain required records (including
those described in § 1068.501). You may
not deny us access to your records or
the ability to copy your records if we
have the authority to see or copy them.
Also, you must give us complete and
accurate reports and information
without delay as required under this
chapter. Failure to comply with the
PO 00000
Frm 00151
Fmt 4701
Sfmt 4702
44591
requirements of this paragraph is
prohibited. We may assess a civil
penalty up to $37,500 for each day you
are in violation. In addition, knowingly
submitting false information is a
violation of 18 U.S.C. 1001, which may
involve criminal penalties and up to
five years imprisonment.
(3) Testing and access to facilities.
You may not keep us from entering your
facility to test engines/equipment or
inspect if we are authorized to do so.
Also, you must perform the tests we
require (or have the tests done for you).
Failure to perform this testing is
prohibited. We may assess a civil
penalty up to $37,500 for each day you
are in violation.
(b) The following prohibitions apply
to everyone with respect to the engines
and equipment to which this part
applies:
(1) Tampering. You may not remove
or render inoperative any device or
element of design installed on or in
engines/equipment in compliance with
the regulations prior to its sale and
delivery to the ultimate purchaser. You
also may not knowingly remove or
render inoperative any such device or
element of design after such sale and
delivery to the ultimate purchaser. This
includes, for example, operating an
engine without a supply of appropriate
quality urea if the emissions control
system relies on urea to reduce NOx
emissions or the use of incorrect fuel or
engine oil that renders the emissions
control system inoperative. Section
1068.120 describes how this applies to
rebuilding engines. See the standardsetting part, which may include
additional provisions regarding actions
prohibited by this requirement. For a
manufacturer or dealer, we may assess
a civil penalty up to $37,500 for each
engine or piece of equipment in
violation. For anyone else, we may
assess a civil penalty up to $3,750 for
each day an engine or piece of
equipment is operated in violation. This
prohibition does not apply in any of the
following situations:
(i) You need to repair the engine/
equipment and you restore it to proper
functioning when the repair is
complete.
(ii) You need to modify the engine/
equipment to respond to a temporary
emergency and you restore it to proper
functioning as soon as possible.
(iii) You modify new engines/
equipment that another manufacturer
has already certified to meet emission
standards and recertify them under your
own family. In this case you must tell
the original manufacturer not to include
the modified engines/equipment in the
original family.

Federal Register / Vol. 74, No. 166 / Friday, August 28, 2009 / Proposed Rules
(2) Defeat devices. You may not
knowingly manufacture, sell, offer to
sell, or install, any part that bypasses,
impairs, defeats, or disables the control
of emissions of any regulated pollutant,
except as explicitly allowed by the
standard-setting part. We may assess a
civil penalty up to $3,750 for each part
in violation.
(3) Stationary engines. For an engine
that is excluded from any requirements
of this chapter because it is a stationary
engine, you may not move it or install
it in any mobile equipment except as
allowed by the provisions of this
chapter. You may not circumvent or
attempt to circumvent the residencetime requirements of paragraph (2)(iii)
of the nonroad engine definition in
§ 1068.30. Anyone violating this
paragraph (b)(3) is deemed to be a
manufacturer in violation of paragraph
(a)(1) of this section. We may assess a
civil penalty up to $37,500 for each day
you are in violation.
(4) Competition engines/equipment.
For uncertified engines/equipment that
are excluded or exempted from any
requirements of this chapter because
they are to be used solely for
competition, you may not use any of
them in a manner that is inconsistent
with use solely for competition. Anyone
violating this paragraph (b)(4) is deemed
to be a manufacturer in violation of
paragraph (a)(1) of this section. We may
assess a civil penalty up to $37,500 for
each day you are in violation.
(5) Importation. You may not import
an uncertified engine or piece of
equipment if it is defined to be new in
the standard-setting part with a model
year for which emission standards
applied. Anyone violating this
paragraph (b)(5) is deemed to be a
manufacturer in violation of paragraph
(a)(1) of this section. We may assess a
civil penalty up to $37,500 for each day
you are in violation. Note the following:
(i) The definition of new is broad for
imported engines/equipment;
uncertified engines and equipment
(including used engines and equipment)
are generally considered to be new
when imported.
(ii) Used engines/equipment that were
originally manufactured before
applicable EPA standards were in effect
are generally not subject to emission
standards.
(6) Warranty, recall, and maintenance
instructions. You must meet your
obligation to honor your emissionrelated warranty under § 1068.115,
including any commitments you
VerDate Nov<24>2008
21:36 Aug 27, 2009
Jkt 217001
identify in your application for
certification. You must also fulfill all
applicable requirements under subpart
F of this part related to emission-related
defects and recalls. You must also
provide emission-related installation
and maintenance instructions as
described in the standard-setting part.
Failure to meet these obligations is
prohibited. Also, except as specifically
provided by regulation, you are
prohibited from directly or indirectly
communicating to the ultimate
purchaser or a later purchaser that the
emission-related warranty is valid only
if the owner has service performed at
authorized facilities or only if the owner
uses authorized parts, components, or
systems. We may assess a civil penalty
up to $37,500 for each engine or piece
of equipment in violation.
(7) Labeling. (i) You may not remove
or alter an emission control information
label or other required permanent label
except as specified in this paragraph
(b)(7) or otherwise allowed by this
chapter. Removing or altering an
emission control information label is a
violation of paragraph (b)(1) of this
section. However, it is not a violation to
remove a label in the following
circumstances:
(A) The engine is destroyed, is
permanently disassembled, or otherwise
loses its identity such that the original
title to the engine is no longer valid.
(B) The regulations specifically direct
you to remove the label. For example,
see § 1068.235.
(C) The part on which the label is
mounted needs to be replaced. In this
case, you must have a replacement part
with a duplicate of the original label
installed by the certifying manufacturer
or an authorized agent, except that the
replacement label may omit the date of
manufacture if applicable. We generally
require labels to be permanently
attached to parts that will not normally
be replaced, but this provision allows
for replacements in unusual
circumstances, such as damage in a
collision or other accident.
(D) The original label is incorrect,
provided that it is replaced with the
correct label from the certifying
manufacturer or an authorized agent.
This allowance to replace incorrect
labels does not affect whether the
application of an incorrect original label
is a violation.
(ii) Removing or altering a temporary
or removable label contrary to the
provisions of this paragraph (b)(7)(ii) is
PO 00000
Frm 00152
Fmt 4701
Sfmt 4702
a violation of paragraph (b)(1) of this
section.
(A) For labels identifying temporary
exemptions, you may not remove or
alter the label while the engine/
equipment is in an exempt status. The
exemption is automatically revoked for
each engine/equipment for which the
label has been removed.
(B) For temporary or removable
consumer information labels, only the
ultimate purchaser may remove the
label.
(iii) You may not apply a false
emission control information label. You
also may not manufacture, sell, or offer
to sell false labels. The application,
manufacture, sale, or offer for sale of
false labels is a violation of this section
(such as paragraph (a)(1) or (b)(2) of this
section). Note that applying an
otherwise valid emission control
information label to the wrong engine is
considered to be applying a false label.
(c) If you cause someone to commit a
prohibited act in paragraph (a) or (b) of
this section, you are in violation of that
prohibition.
(d) Exemptions from these
prohibitions are described in subparts C
and D of this part and in the standardsetting part.
(e) The standard-setting parts describe
more requirements and prohibitions that
apply to manufacturers (including
importers) and others under this
chapter.
(f) The specification of prohibitions
and penalties in this part does not limit
the prohibitions and penalties described
in the Clean Air Act. Additionally, a
single act may trigger multiple
violations under this section and the
Act. We may pursue all available
administrative, civil, or criminal
remedies for those violations even if the
regulation references only a single
prohibited act in this section.
(g) [Reserved]
(h) The maximum penalty values
listed in paragraphs (a) and (b) of this
section apply as of January 12, 2009.
Maximum penalty values for earlier
violations are published in 40 CFR part
19. Maximum penalty limits may be
adjusted after January 12, 2009 based on
the Consumer Price Index. The specific
regulatory provisions for changing the
maximum penalties, published in 40
CFR part 19, reference the applicable

revising paragraph (a) to read as follows:
§ 1068.103 What are the provisions related
to the duration and applicability of
certificates of conformity?
(a) Engines/equipment covered by a
certificate of conformity are limited to
those that are produced during the
period specified in the certificate and
conform to the specifications described
in the certificate and the associated
application for certification. For the
purposes of this paragraph (a),
specifications includes any conditions
or limitations identified by the
manufacturer or EPA, but does not
include any information provided in the
application that is not relevant to a
demonstration of compliance with
applicable regulations. For example, if
the application for certification specifies
certain engine configurations, the
certificate does not cover any
configurations that are not specified.
However, your certificate would not be
conditioned upon your actual U.S.directed production volumes matching
the volumes you projected in your
application.

(a) Transitioning to new engine-based
standards. If new engine-based emission
standards apply in a given model year,
your equipment in that calendar year
must have engines that are certified to
the new standards, except that you may
continue to use up your normal
inventory of earlier engines that were
built before the date of the new or
changed standards. (Note: This
paragraph (a) does not apply in the case
of new remanufacturing standards.) For

example, if your normal inventory
practice is to keep on hand a one-month
supply of engines based on your
upcoming production schedules, and a
new tier of standards starts to apply for
the 2015 model year, you may order
engines consistent with your normal
inventory requirements late in the
engine manufacturer’s 2014 model year
and install those engines in your
equipment, regardless of the date of
installation. Also, if your model year
starts before the end of the calendar year
preceding new standards, you may use
engines from the previous model year
for those units you produce before
January 1 of the year that new standards
apply. If emission standards for the
engine do not change in a given model
year, you may continue to install
engines from the previous model year
without restriction (or any earlier model
year for which the same standards
apply). You may not circumvent the
provisions of § 1068.101(a)(1) by
stockpiling engines that were built
before new or changed standards take
effect. Note that this allowance does not
apply for equipment subject to
equipment-based standards. See 40 CFR

apply for equipment subject to
evaporative emission standards.

configuration is as clean or cleaner than
the original configuration. For purposes
of this paragraph (e), ‘‘as clean or
cleaner’’ means one of the following:
(1) For engines not certified with a
Family Emission Limit for calculating
credits for a particular pollutant, this
means that the same emission standard
applied for both model years. This
includes supplemental standards such
as Not-to-Exceed standards.
(2) For engines certified with a Family
Emission Limit for a particular
pollutant, this means that the
configuration to which the engine is
being rebuilt has a Family Emission
Limit for that pollutant that is at or
below the standard that applied to the
engine originally, and is at or below the
original Family Emission Limit.

(b) Administrative penalties. Instead
of bringing a civil action, we may assess
administrative penalties if the total is
less than $295,000 against you
individually. This maximum penalty
may be greater if the Administrator and
the Attorney General jointly determine
that a greater administrative penalty
assessment is appropriate, or if the limit
is adjusted under 40 CFR part 19. No
court may review this determination.
Before we assess an administrative
penalty, you may ask for a hearing
(subject to 40 CFR part 22). The
Administrator may compromise or
remit, with or without conditions, any
administrative penalty that may be
imposed under this section.

§ 1068.215 What are the provisions for
exempting manufacturer-owned engines/
equipment?
(a) You are eligible for the exemption
for manufacturer-owned engines/
equipment only if you are a certificate
holder. Any engine for which you meet
all applicable requirements under this
section is exempt without request.
(b) Engines/equipment may be exempt
without a request if they are
nonconforming engines/equipment
under your ownership, possession, and
control and you do not operate them for
purposes other than to develop
products, assess production methods, or
promote your engines/equipment in the
marketplace, or other purposes we
approve. You may not loan, lease, sell,
or use the engine/equipment to generate
revenue, either by itself or for an engine
installed in a piece of equipment, except
as allowed by § 1068.201(i). Note that
this paragraph (b) does not prevent the
sale or shipment of a partially complete
engine to a secondary engine

(c) Previous-tier replacement engines
without tracking. You may produce a
limited number of new replacement
engines that are not from a currently
certified engine family under the
provisions of this paragraph (c). If you
produce new engines under this
paragraph (c) to replace engines subject
to emission standards, the new
replacement engine must be in a
configuration identical in all material
respects to the old engine and meet the
requirements of § 1068.265. This would
apply, for example, for engine
configurations that were certified in an
earlier model year but are no longer
covered by a certificate of conformity.
You must comply with the requirements
of paragraph (b) of this section for any
number of replacement engines you
produce in excess of what we allow
under this paragraph (c). The following
provisions apply to engines exempted
under this paragraph (c):
*
*
*
*
*
(d) Partially complete engines. The
following requirements apply if you
ship a partially complete replacement
engine under paragraph (b) or (c) of this
section:
(1) Include installation instructions
specifying how to complete the engine
assembly such that the resulting engine
conforms to the applicable certificate of
conformity or the specifications of
§ 1068.265. Where a partially complete
engine can be built into multiple
different configurations, you must be
able to identify all the engine models
and model years for which the partially
complete engine may properly be used
for replacement purposes. Your
installation instructions must make
clear how the final assembler can
determine which configurations are
appropriate for the engine they receive.
(2) You must label the engine as
follows:
(i) If you have a reasonable basis to
believe that the fully assembled engine
will include the original emission
control information label, you may add
a removable label to the engine with
your corporate name and trademark and
PO 00000
Frm 00154

Sfmt 4702
the statement: ‘‘This replacement engine
is exempt under 40 CFR 1068.240(b) [or
40 CFR 1068.240(c) if appropriate].’’
This would generally apply if all the
engine models that are compatible with
the replacement engine were covered by
a certificate of conformity and they were
labeled in a position on the engine or
equipment that is not included as part
of the partially complete engine being
shipped for replacement purposes.
Removable labels must meet the
requirements specified in § 1068.45.
(ii) If you do not qualify for using a
removable label in paragraph (d)(1) of
this section, you must add a permanent
label in a readily visible location,
though it may be obscured after
installation in a piece of equipment.
Include on the permanent label your
corporate name and trademark, the
engine’s part number (or other
identifying information), and the
statement: ‘‘This replacement engine is
exempt under 40 CFR 1068.240(b) [or 40
CFR 1068.240(c) if appropriate].’’ If
there is not enough space for this
statement, you may alternatively add:
‘‘REPLACEMENT’’ or ‘‘SERVICE
ENGINE’’. For purposes of this
paragraph (d)(2), engine part numbers
permanently stamped or engraved on
the engine are considered to be included
on the label.
(e) Partially complete current-tier
replacement engines. The provisions of
paragraph (d) of this section apply for
partially complete engines you produce
from a current line of certified engines
or vehicles, except that the appropriate
regulatory cite on the label is 40 CFR
1068.240(e). This applies for enginebased and equipment-based standards
as follows:
(1) Where engine-based standards
apply, you may introduce into U.S.
commerce short blocks or other partially
complete engines from a currently
certified engine family as replacement
components for in-use equipment
powered by engines you originally
produced. You must be able to identify
all the engine models and model years
for which the partially complete engine
may properly be used for replacement
purposes.
(2) Where equipment-based standards
apply, you may introduce into U.S.
commerce engines that are identical to
engines covered by a current certificate
of conformity by demonstrating
compliance with currently applicable
standards where the engines will be
installed as replacement engines. These
engines might be fully assembled, but
we would consider them to be partially

Control of Emissions From New Marine Compression-Ignition Engines
at or Above 30 Liters per Cylinder
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed Rule.
-----------------------------------------------------------------------
SUMMARY: EPA is proposing emission standards for new marine diesel
engines with per cylinder displacement at or above 30 liters (called
Category 3 marine diesel engines) installed on U.S. vessels, under
section 213 of the Clean Air Act (CAA or ``the Act''). The proposed
engine standards are equivalent to the nitrogen oxides (NOX)
limits recently adopted in the amendments to Annex VI to the
International Convention for the Prevention of Pollution from Ships
(MARPOL Annex VI) and are based on the position advanced by the United
States Government as part of those international negotiations. The
near-term standards for newly-built engines would apply beginning in
2011. Long-term standards would begin in 2016 and are based on the
application of high-efficiency aftertreatment technology. We are also
proposing a change to our diesel fuel program that would forbid the
production and sale of marine fuel oil above 1,000 ppm sulfur for use
in the waters within the proposed U.S. ECA and internal U.S. waters and
allow for the production and sale of 1,000 ppm sulfur fuel for use in
Category 3 marine vessels.
This proposal is part of a coordinated strategy to ensure that all
ships that affect U.S. air quality meet stringent NOX and
fuel sulfur requirements. In addition, on March 27, 2009, the U.S.
Government forwarded a proposal to the International Maritime
Organization (IMO) to amend MARPOL Annex VI to designate an Emission
Control Area (ECA) off U.S. coasts. If this proposed amendment is not
timely adopted by IMO, we intend to take supplemental action to control
emissions from vessels affecting U.S. air quality.
We project that in 2030 this coordinated strategy would reduce
annual emissions of NOX and particulate matter (PM) from
ocean-going vessels by 1.2 million and 143,000 tons, respectively.
These reductions are estimated to annually prevent between 13,000 and
32,000 PM-related premature deaths, between 220 and 980 ozone-related
premature deaths, 1,500,000 work days lost, and 10,000,000 minor
restricted-activity days. The estimated annual monetized health
benefits of this coordinated strategy in 2030 would be between $110 and
$280 billion, assuming a 3 percent discount rate (or between $100 and
$260 billion assuming a 7 percent discount rate). The annual costs
would be significantly less, at approximately $3.1 billion.
The proposed regulations also include technical amendments to our
motor vehicle and nonroad engine regulations. Many of these changes
involve minor adjustments or corrections to our recently finalized rule
for new nonroad spark-ignition engines, or adjustment to other
regulatory provisions to align with this recent final rule.

I. Overview
This proposal is part of a coordinated strategy to address
emissions from ocean-going vessels and is an important step in EPA's
ongoing National Clean Diesel Campaign (NCDC). In recent years, we have
adopted major new programs designed to reduce emissions from new diesel
engines, including those used in highway (66 FR 5001, January 18,
2001), nonroad (69 FR 38957, June 29, 2004), locomotive, and marine
applications (73 FR 25098, May 6, 2008). When fully phased in, these
programs will significantly reduce emissions of harmful regulated
pollutants from these categories of engines and vehicles. This Notice
of Proposed Rulemaking (NPRM) sets out the next step in this ambitious
effort by addressing emissions from the largest marine diesel engines,
called Category 3 (C3) marine diesel engines. These are engines with
per cylinder displacement at or above 30 liters per cylinder, which are
used primarily for propulsion power on ocean-going vessels (OGV).
Emissions from OGV remain at high levels. The Category 3 engines on
these vessels use emission control technology that is comparable to
that used by nonroad engines in the early 1990s, and use fuel that can
have a sulfur content of 30,000 ppm or more. As a result, these engines
emit high levels of pollutants that contribute to unhealthy air in many
areas of the U.S. Nationally, in 2009, emissions from Category 3
engines account for about 10 percent of mobile source nitrogen oxides
(NOX) emissions, about 24 percent of mobile source diesel
PM2.5 emissions (with PM2.5 referring to
particles with a nominal mean aerodynamic diameter less than or equal
to 2.5 [micro]m), and about 80 percent of mobile source sulfur oxides
(SOX) emissions. As we look into the future, however,
emissions from ocean-going vessels are expected to become a dominant
inventory source. This will be due to both emission reductions from
other mobile sources as new emission controls go into effect and to the
anticipated activity growth for ocean transportation. Without new
controls, we anticipate the contribution of ocean-going vessels to
national emission inventories to increase to about 24 percent, 34
percent, and 93 percent of mobile source NOX,
PM2.5, and SOX emissions, respectively in 2020,
growing to 40 percent, 48 percent, and 95 percent respectively in 2030.
The coordinated emission control strategy will lead to significant
reductions in these emissions and important benefits to public health.
The evolution of EPA's strategy to control mobile source diesel
emissions has followed a technology progression, beginning with the
application of high-efficiency advanced aftertreatment approaches and
low sulfur fuel requirements first to highway vehicles, then to nonroad
engines and equipment, followed by locomotives and smaller marine
diesel engines. The benefits of this approach include maximizing air
quality benefits by focusing on the largest populations of sources with
the shortest service lives, allowing engine manufacturers to spread
initial research and development costs over a larger population of
engines, and allowing manufacturers to address the challenges of
applying advanced emission controls on smaller engines.
EPA has been working with engine manufacturers and other industry
stakeholders for many years to identify and resolve challenges
associated with applying advanced diesel engine technology to Category
3 engines to achieve significant NOX emission reductions.
This work was fundamental in developing the emission limits for
Category 3 engines that we are proposing in this action and informed
the position advocated by the United States in the international
negotiations for more stringent tiers of international engine emission
limits.
Our coordinated strategy to control emissions from ocean-going
vessels consists of actions at both the national and international
levels. It includes: (1) The engine and fuel controls we are proposing
in this action under our Clean Air Act authority; (2) the proposal \1\
submitted by the United States Government (USG) to the International
Maritime Organization (IMO) to amend Annex VI of the International
Convention for the Prevention of Pollution from Ships (MARPOL Annex VI)
to designate U.S. coasts as an Emission Control Area (ECA) \2\ in which
all vessels, regardless of flag, would be required to meet the most
stringent engine and marine fuel sulfur requirements in Annex VI; and
(3) the new engine emission and fuel sulfur limits contained in the
amendments to Annex VI that are applicable to all vessels regardless of
flag and that are implemented in the U.S. through the Act to Prevent
Pollution from Ships (APPS).
---------------------------------------------------------------------------
\1\ Proposal to Designate an Emission Control Area for Nitrogen
Oxides, Sulphur Oxides and Particulate Matter, Submitted by the
United States and Canada. IMO Document MEPC59/6/5, 27 March, 2009. A
copy of this document can be found at https://www.epa.gov/otaq/regs/nonroad/marine/ci/mepc-59-eca-proposal.pdf.
\2\ For the purpose of this proposal, the term ``ECA'' refers to
both the ECA and internal U.S. waters. Refer to Section VI.B. for a
discussion of the application of the fuel sulfur and engine emission
limits to U.S. internal waters through APPS.
---------------------------------------------------------------------------
The amendments to APPS to incorporate Annex VI provide the
authority to ensure compliance with MARPOL Annex VI by U.S. and foreign
vessels that enter U.S. ports or operate in U.S. waters. In light of
this, we are deciding not to revisit our existing approach with respect
to foreign vessels in this rule. However, the MARPOL Annex VI Tier III
NOX and stringent fuel sulfur limits are geographically
based and would not become effective absent designation of U.S. coasts
as an ECA. As noted above, the United States forwarded a proposal to
IMO to amend Annex VI to designate U.S. coasts as an ECA. If this
amendment is not adopted in a timely manner by IMO, we intend to take
supplemental action to control emissions from vessels that affect U.S.
air quality.
Our coordinated strategy for ocean-going vessels would
significantly reduce emissions from foreign and domestic
[[Page 44445]]
vessels that affect U.S. air quality, and the impacts on human health
and welfare would be substantial. We project that by 2030 this program
would reduce annual emissions of NOX and particulate matter
(PM) by 1.2 million and 143,000 tons, respectively, and the magnitude
of these reductions would continue to grow well beyond 2030.\3\ These
reductions are estimated to annually prevent between 13,000 and 32,000
PM-related premature deaths, between 220 and 980 ozone-related
premature deaths, 1,500,000 work days lost, and 10,000,000 minor
restricted-activity days. The estimated annual monetized health
benefits of this coordinated strategy in 2030 would be between $110 and
$280 billion, assuming a 3 percent discount rate (or between $100 and
$260 billion assuming a 7 percent discount rate). The annual cost of
the overall program in 2030 would be significantly less, at
approximately $3.1 billion.
---------------------------------------------------------------------------
\3\ These emission inventory reductions include reductions from
ships operating within the 24 nautical mile regulatory zone off the
California Coastline, beginning with the effective date of the
Coordinated Strategy program elements. The California regulation
contains a provision that would sunset the requirements of the rule
if the Federal program achieves equivalent emission reductions. See
https://www.arb.ca.gov/regact/2008/fuelogv08/fro13.pdf at 13 CCR
2299.2(j)(1).
---------------------------------------------------------------------------
A. What Are the Elements of EPA's Coordinated Strategy for Ocean-Going
Vessels?
Our coordinated strategy for ocean-going vessels, including the CAA
emission standard proposed in this action, continues EPA's program to
progressively apply advanced aftertreatment emission control standards
to diesel engines and reflects the evolution of this technology from
the largest inventory source (highway engines), to land-based nonroad
engines, to locomotives and marine diesel engines up to 30 liters per
cylinder. The results of these forerunner programs are dramatic
reductions in NOX and PM2.5 emissions on the
order of 80 to 90 percent, which will lead to significant improvements
in national air quality.
The combination of controls in the coordinated strategy for ocean-
going vessels is expected to provide significant reductions in
PM2.5, NOX, SOX, and toxic compounds,
both in the near term (as early as 2011) and in the long term. These
reductions would be achieved in a manner that: (1) Is very cost
effective compared to additional controls on portside vehicles and
equipment and other land-based mobile sources that are already subject
to stringent technology-forcing emission standards; (2) leverages the
international program adopted by IMO to ensure that all ships that
operate in areas that affect U.S. air quality are required to use
stringent emission control technology; and (3) provides the lead time
needed to deal with the engineering design workload that is involved in
applying advanced high-efficiency aftertreatment technology to these
very large engines. Overall, the coordinated strategy constitutes a
comprehensive program that addresses the problems caused by ocean-going
vessel emissions from both a near-term and long-term perspective. It
does this while providing for an orderly and cost-effective
implementation schedule for the vessel owners and manufacturers, and in
a way that is consistent with the international requirements for these
vessels.
The human health and welfare impacts of emissions from ocean-going
vessels, along with estimates of their contribution to national
emission inventories, are described in Section II. The proposed new
tiers of Clean Air Act engine emission standards to address these
emissions, and our justifications for them, are discussed in Section
III. Section IV contains proposed changes to our existing marine diesel
fuel program. In Section V, we describe a key component of the
coordinated strategy: the recently-submitted proposal to amend MARPOL
Annex VI to designate U.S. coasts as an ECA, as well as the IMO
approval process.
In addition to the new emission limits, we are proposing several
revisions to our Clean Air Act testing, certification, and compliance
provisions to better ensure emissions control in use. We are also
proposing several regulations for the purpose of implementing MARPOL
Annex VI pursuant to the Act to Prevent Pollution From Ships (33 USC
1901 et seq.). These revisions are described in Section VI. Sections
VII and VIII present the estimated costs and benefits of our
coordinated program to address OGV emissions, and Section IX presents
the analysis of programmatic alternatives and a discussion of a
potential Voluntary Marine Verification Program.
(1) What CAA Standards Is EPA Proposing?
We are proposing new tiers of Category 3 marine diesel engine
standards under our Clean Air Act authority, as well as certain
revisions to our marine fuel program.
Category 3 Engine Standards. Our current standards for Category 3
engines were adopted in 2003. These Tier 1 standards are equivalent to
the first tier of MARPOL Annex VI NOX limits and require the
use of control technology comparable to that used by nonroad engines in
the early 1990s. We did not adopt PM standards at that time because the
vast majority of PM emissions from Category 3 engines are the result of
the sulfur content of the residual fuel they use and because of
measurement issues.\4\ The combination of the engine and fuel standards
we are proposing in this NPRM and the USG proposal for ECA designation
will require all vessels that operate in coastal areas that affect U.S.
air quality to meet advanced engine standards and fuel controls.
---------------------------------------------------------------------------
\4\ As explained in the NPRM, there were no acceptable
procedures for measuring PM from Category 3 marine engines.
Specifically, established PM test methods showed unacceptable
variability when sulfur levels exceed 0.8 weight percent, which was
common at that time for both residual and distillate marine fuels
for Category 3 engines, and no PM test method or calculation
methodology had been developed to correct that variability for these
engines. See 67 FR 37569, May 29, 2002.
---------------------------------------------------------------------------
We are proposing to revise our CAA engine program to include two
additional tiers of NOX standards for new marine diesel
engines with per cylinder displacement at or above 30 liters (Category
3 engines) installed on vessels flagged or registered in the United
States. The proposed near-term Tier 2 standards would apply beginning
in 2011 and would require more efficient use of engine technologies
being used today, including engine timing, engine cooling, and advanced
computer controls. The proposed long-term Tier 3 standards would apply
beginning in 2016 and would require the use of high-efficiency
aftertreatment technology such as selective catalytic reduction.
Because much of the operation of U.S. vessels occurs in areas that
would have little, if any, impact on U.S. air quality, we are proposing
that our Clean Air Act program allow the use of alternative emission
control devices (AECDs) that would permit a ship to meet less stringent
requirements on the open sea. The use of these devices would be subject
to certain restrictions, including a requirement that the AECD not
disable emission controls while operating in areas where emissions
could reasonably be expected to adversely affect U.S. air quality, and
that the engine is equipped with a NOX emission monitoring
device. In addition, the engine would be required to meet the Tier 2
NOX limits when the AECD is implemented, and an AECD would
not be allowed on any Tier 2 or earlier engine.
In addition to the NOX emission limits, we are proposing
standards for emissions of hydrocarbons (HC) and carbon monoxides (CO)
from new Category 3 engines. As explained in
[[Page 44446]]
Section III.B.1, below, we are not proposing to set a standard for PM
emissions for Category 3 engines. However, significant PM emissions
benefits will be achieved through the ECA fuel sulfur requirements that
will apply to ships that operate in areas that affect U.S. air quality.
We are also proposing to require engine manufacturers to measure and
report PM emissions pursuant to our authority in section 208 of the
Act.
Fuel Sulfur Limits. EPA is in this notice proposing fuel sulfur
limits under section 211(c) of the Clean Air Act that match the limits
that apply under Annex VI in ECAs. First, we are proposing to forbid
the production and sale of fuel oil with a sulfur content above 1,000
ppm for use in the waters within the proposed ECA (as well as internal
U.S. waters). Second, we are proposing a revision to our existing
diesel fuel program to allow for the production and sale of 1,000 ppm
sulfur fuel for use in Category 3 marine vessels. This would allow
production and distribution of fuel consistent with the new sulfur
limits that will become applicable, under Annex VI, in ECAs beginning
in 2015. Our current diesel fuel program sets a sulfur limit of 15 ppm
that will be fully phased-in by December 1, 2014 for nonroad,
locomotive, and marine (NRLM) diesel fuel produced for distribution/
sale and use in the U.S. Without this proposed change to our existing
diesel fuel regulations, fuel with a sulfur content of up to 1,000 ppm
could be used in C3 marine vessels, but it could not be legally
produced in the U.S. after June 1, 2014.
(2) What is the United States Government Proposal for Designation of an
Emission Control Area?
MARPOL Annex VI contains the international standards for air
emissions from ships, including NOX and SOX /PM
emissions. The Annex VI NOX and SOX /PM limits
are set out in Table I-1. Annex VI was originally adopted by the
Parties in 1997 but did not go into force until 2005, after it was
ratified by fifteen countries representing at least 50 percent of the
world's merchant shipping tonnage. The initial program consisted of
engine NOX emission standards and fuel sulfur limits. The
NOX standards apply to all engines above 130 kW installed on
a ship constructed on or after January 1, 2000 and were intended to
reduce NOX emissions by about 30 percent from uncontrolled.
There were two fuel sulfur limits: A global limit of 45,000 ppm and a
more stringent 15,000 ppm limit that applies in SOX Emission
Control Areas (SECAs). This approach ensured that the cleanest fuel was
used in areas that demonstrated a need for additional SOX
reductions, while retaining the ability of ships to use higher sulfur
residual fuel on the open ocean.
Annex VI was amended in October 2008, adding two tiers of
NOX limits (Tier II and Tier III) and two sets of fuel
sulfur standards.\5\ These amendments will enter into force on July 1,
2010 unless an objection is raised before January 1, 2010 by at least
one-third of the parties to the Annex or by parties that represent at
least 50 percent of the world's gross merchant tonnage. The most
stringent NOX and fuel sulfur limits are regionally based
and will apply only in designated ECAs.
---------------------------------------------------------------------------
\5\ Note that the MARPOL Annex VI standards are referred to as
Tiers I, II, and III; EPA's Category 3 emission standards are
referred to as Tiers 1, 2, and 3.

To realize the benefits from the MARPOL Annex VI Tier III
NOX and fuel sulfur controls, areas must be designated as
Emission Control Areas. On March 27, 2009, the U.S. and Canadian
governments submitted a proposal to amend MARPOL Annex VI to designate
North American coastal waters as an ECA (referred to as the ``U.S./
Canada ECA'' or the ``North American ECA'').\6\ A description of this
submittal and the IMO approval process is set out in Section V. ECA
designation would ensure that ships that affect U.S. air quality meet
stringent NOX and fuel sulfur requirements while operating
within 200 nautical miles of U.S. coasts. We expect the U.S./Canadian
proposal will be adopted by the Parties to MARPOL Annex VI in March
2010. If, however, the proposed amendment is not adopted in a timely
manner, we intend to take supplemental action to control harmful
emissions from vessels that affect U.S. air quality.

---------------------------------------------------------------------------
(3) Regulations To Implement Annex VI
The United States became a party to MARPOL Annex VI by depositing
its instrument of ratification with IMO on October 8, 2008. This was
preceded by the President signing into law the Maritime Pollution
Prevention Act of 2008 (Pub. L. 110-280) on July 21, 2008, that
contains amendments to the Act to Prevent Pollution from Ships (33
U.S.C. 1901 et seq.). These APPS amendments require compliance with
Annex VI by all persons subject to the engine and
[[Page 44447]]
vessel requirements of Annex VI. The amendments also authorize the
United States Coast Guard and EPA to enforce the provisions of Annex VI
against domestic and foreign vessels and to develop implementing
regulations, as necessary. In addition, APPS gives EPA sole authority
to certify engines installed on U.S. vessels to the Annex VI
requirements. This NPRM contains proposed regulations to implement
several aspects of the Annex VI engine and fuel regulations, which we
are proposing under that APPS authority. Our cost and benefit analyses
for the coordinated strategy includes the costs for U.S. vessels of
implementing those provisions of the MARPOL Annex VI program that are
in addition to the ECA requirements.
(4) Technical Amendments
The proposed regulations also include technical amendments to our
motor vehicle and nonroad engine regulations. Many of these changes
involve minor adjustments or corrections to our recently finalized rule
for new nonroad spark-ignition engines, or adjustment to other
regulatory provisions to align with this recent final rule.
(5) Summary
The coordinated strategy emission control requirements are the
MARPOL Annex VI global Tier II NOX standards included in the
amendments to Annex VI and the ECA Tier 3 NOX limits and
fuel sulfur limits that will apply when the U.S. coasts are designated
as an ECA through an additional amendment to Annex VI. The Annex VI
requirements, including the future ECA requirements, will be
enforceable for U.S. and foreign vessels operating in the United States
waters through the Act to Prevent Pollution from Ships.
We are also adopting the engine controls for Category 3 engines on
U.S. vessels under our Clean Air Act program, as required by Section
213 of the Act.
Finally, we are proposing additional requirements that are not part
of the Annex VI program or the ECA. These are: Limits on hydrocarbon
and carbon monoxide emissions for Category 3 engines; PM measurement
requirement, to obtain data on PM emissions from engines operating on
distillate fuel; and changes to our Clean Air Act diesel fuel program
to allow production and sale of ECA-compliant fuel. We are also
considering changes to our emission control program for smaller marine
diesel engines to harmonize with the Annex VI NOX
requirements, for U.S. vessels that operate internationally.
B. Why is EPA Making This Proposal?
(1) OGV Contribute to Serious Air Quality Problems
Ocean-going vessels subject to this proposal generate significant
emissions of PM2.5, SOX, and NOX that
contribute to nonattainment of the National Ambient Air Quality
Standards (NAAQS) for PM2.5 and ground-level ozone (smog).
NOX and SOX are both precursors to secondary
PM2.5 formation. Both PM2.5 and NOX
adversely affect human health. NOX is a key precursor to
ozone as well. NOX, SOX and PM2.5
emissions from ocean-going vessels also cause harm to public welfare,
including contributing to deposition of nitrogen and sulfur, visibility
impairment and other harmful environmental impacts across the U.S.
The health and environmental effects associated with these
emissions are a classic example of a negative externality (an activity
that imposes uncompensated costs on others). With a negative
externality, an activity's social cost (the costs borne to society
imposed as a result of the activity taking place) is not taken into
account in the total cost of producing goods and services. In this
case, as described in this section below and in Section II, emissions
from ocean-going vessels impose public health and environmental costs
on society, and these added costs to society are not reflected in the
costs of providing the transportation services. The market system
itself cannot correct this externality because firms in the market are
rewarded for minimizing their production costs, including the costs of
pollution control. In addition, firms that may take steps to use
equipment that reduces air pollution may find themselves at a
competitive disadvantage compared to firms that do not. To correct this
market failure and reduce the negative externality from these
emissions, we propose to set a cap on the rate of emission production
from these sources. EPA's coordinated strategy for ocean-going vessels
will accomplish this since both domestic and foreign ocean-going
vessels will be required to reduce their emissions to a technologically
feasible limit.
Emissions from ocean-going vessels account for substantial portions
of the country's ambient PM2.5, SOX and
NOX levels. We estimate that in 2009 these engines account
for about 80 percent of mobile source sulfur dioxide (SO2)
emissions, 10 percent of mobile source NOX emissions and
about 24 percent of mobile source diesel PM2.5 emissions.
Emissions from ocean-going vessels are expected to dominate the mobile
source inventory in the future, due to both the expected emission
reductions from other mobile sources as a result of more stringent
emission controls and due to growth in the demand for ocean
transportation services. By 2030, the coordinated strategy would reduce
annual SO2 emissions from these diesel engines by 1.3
million tons, annual NOX emissions by 1.2 million tons, and
PM2.5 emissions by 143,000 tons, and those reductions would
continue to grow beyond 2030 as fleet turnover to the clean engines
continues. While a share of these emissions occur at sea, our air
quality modeling results described in Section II show they have a
significant impact on ambient air quality far inland.
Both ozone and PM2.5 are associated with serious public
health problems, including premature mortality, aggravation of
respiratory and cardiovascular disease (as indicated by increased
hospital admissions and emergency room visits, school absences, lost
work days, and restricted activity days), changes in lung function and
increased respiratory symptoms, altered respiratory defense mechanisms,
and chronic bronchitis. Diesel exhaust is of special public health
concern, and since 2002 EPA has classified it as likely to be
carcinogenic to humans by inhalation at environmental exposures. Recent
studies are showing that populations living near large diesel emission
sources such as major roadways, rail yards, and marine ports are likely
to experience greater diesel exhaust exposure levels than the overall
U.S. population, putting them at greater health risks.7 8 9

EPA recently updated its initial screening-level analysis \10\ of
selected marine port areas to better understand the populations that
are exposed to diesel particulate matter emissions from
[[Page 44448]]
these facilities.11 12 13 14 This screening-level analysis
focused on a representative selection of national marine ports.\15\ Of
the 45 marine ports selected, the results indicate that at least 18
million people, including a disproportionate number of low-income
households, African-Americans, and Hispanics, live in the vicinity of
these facilities and are being exposed to ambient diesel PM levels that
are 2.0 [mu] g/m\3\ and 0.2 [mu] g/m\3\ above levels found in areas
further from these facilities. Considering only ocean-going marine
engine diesel PM emissions, the results indicate that 6.5 million
people are exposed to ambient diesel particulate matter (DPM) levels
that are 2.0 [mu]g/m \3\ and 0.2 [mu] g/m\3\ above levels found in
areas further from these facilities. Because those populations exposed
to diesel PM emissions from marine ports are more likely to be low-
income and minority residents, these populations would benefit from the
controls being proposed in this action. The detailed findings of this
study are available in the public docket for this rulemaking.
---------------------------------------------------------------------------
\10\ This type of screening-level analysis is an inexact tool
and not appropriate for regulatory decision-making; it is useful in
beginning to understand potential impacts and for illustrative
purposes. Additionally, the emissions inventories used as inputs for
the analyses are not official estimates and likely underestimate
overall emissions because they are not inclusive of all emission
sources at the individual ports in the sample.

150 U.S. ports including coastal and Great Lake ports.
---------------------------------------------------------------------------
Even outside port areas, millions of Americans continue to live in
areas that do not meet existing air quality standards today. With
regard to PM2.5 nonattainment, in 2005 EPA designated 39
nonattainment areas for the 1997 PM2.5 NAAQS (70 FR 943,
January 5, 2005). These areas are composed of 208 full or partial
counties with a total population exceeding 88 million. The 1997
PM2.5 NAAQS was recently revised and the 2006
PM2.5 NAAQS became effective on December 18, 2006. As of
December 22, 2008, there are 58 2006 PM2.5 nonattainment
areas composed of 211 full or partial counties. These numbers do not
include individuals living in areas that may fail to maintain or
achieve the PM2.5 NAAQS in the future. Currently, ozone
concentrations exceeding the 8-hour ozone NAAQS occur over wide
geographic areas, including most of the nation's major population
centers. As of December 2008, there are approximately 132 million
people living in 57 areas (293 full or partial counties) designated as
not in attainment with the 8-hour ozone NAAQS. These numbers do not
include people living in areas where there is a potential that the area
may fail to maintain or achieve the 8-hour ozone NAAQS.
In addition to public health impacts, there are serious public
welfare and environmental impacts associated with PM2.5 and
ozone emissions. Specifically, NOX and SOX
emissions from diesel engines contribute to the acidification,
nitrification, and eutrophication of water bodies. NOX,
SOX and direct emissions of PM2.5 can contribute
to the substantial impairment of visibility in many parts of the U.S.
where people live, work, and recreate, including national parks,
wilderness areas, and mandatory class I Federal areas.\16\ The
deposition of airborne particles can also reduce the aesthetic appeal
of buildings and culturally important articles through soiling, and can
contribute directly (or in conjunction with other pollutants) to
structural damage by means of corrosion or erosion. Finally, ozone
causes damage to vegetation which leads to crop and forestry economic
losses, as well as harm to national parks, wilderness areas, and other
natural systems.
---------------------------------------------------------------------------
\16\ These areas are defined in section 162 of the Act as those
national parks exceeding 6,000 acres, wilderness areas and memorial
parks exceeding 5,000 acres, and all international parks which were
in existence on August 7, 1977. Section 169 of the Clean Air Act
provides additional authority to address existing visibility
impairment and prevent future visibility impairment in the 156
national parks, forests and wilderness areas categorized as
mandatory class I Federal areas.
---------------------------------------------------------------------------
While EPA has already adopted many emission control programs that
are expected to reduce ambient PM2.5 and ozone levels,
including the Nonroad Spark Ignition Engine rule (73 FR 59034, Oct. 8,
2008), the Locomotive and Marine Diesel Engine Rule (73 FR 25098, May
6, 2008), the Clean Air Interstate Rule (CAIR) (70 FR 25162, May 12,
2005) and the Clean Air Nonroad Diesel Rule (69 FR 38957, June 29,
2004), the Heavy Duty Engine and Vehicle Standards and Highway Diesel
Fuel Sulfur Control Requirements (66 FR 5002, Jan. 18, 2001), and the
Tier 2 Vehicle and Gasoline Sulfur Program (65 FR 6698, Feb. 10, 2000),
the additional PM2.5, SOX and NOX
emission reductions resulting from the coordinated approach described
in this action would assist states in attaining and maintaining the
PM2.5 and ozone NAAQS near term and in the decades to come.
Air quality modeling conducted by EPA projects that in 2020 at
least 13 counties with about 30 million people may violate the 1997
standards for PM2.5 and 50 counties with about 50 million
people may violate the 2008 standards for ozone. These numbers likely
underestimate the impacted population since they do not include the
people who live in areas which do not meet the 2006 PM2.5
NAAQS. In addition, these numbers do not include the additional 13
million people in 12 counties who live in areas that have air quality
measurements within 10 percent of the 1997 PM2.5 NAAQS and
the additional 80 million people in 135 counties who live in areas that
have air quality measurements within 10% of the 2008 ozone NAAQS. The
emission reductions resulting from this coordinated strategy would
assist these and other states to both attain and maintain the
PM2.5 and ozone NAAQS.
State and local governments are working to protect the health of
their citizens and comply with requirements of the Clean Air Act. As
part of this effort, they recognize the need to secure additional major
reductions in diesel PM2.5, SOX and
NOX emissions by undertaking numerous state level actions,
while also seeking Agency action, including the setting of the CAA
Category 3 engine standards being proposed in this NPRM and the U.S.
proposal to IMO to amend Annex VI to designate U.S. coastal areas as an
ECA, and related CAA certification and fuel provisions to complement
that ECA proposal. EPA's coordinated strategy to reduce OGV emissions
through engine emission controls and fuel sulfur limits would play a
critical part in state efforts to attain and maintain the NAAQS through
the next two decades.
In addition to regulatory programs, the Agency has a number of
innovative programs that partner government, industry, and local
communities together to help address challenging air quality problems.
Under the National Clean Diesel Campaign, EPA promotes a variety of
emission reduction strategies such as retrofitting, repairing,
replacing and repowering engines, reducing idling and switching to
cleaner fuels.
In 2008, Congress appropriated funding for the Diesel Emissions
[[Page 44449]]
Reduction Program (DERA) under the Energy Policy Act of 2005 (EPAct
2005) to reduce emissions from heavy-duty diesel engines in the
existing fleet. The EPAct 2005 directs EPA to break the funding into
two different components: A National competition and a State allocation
program. The National Program, with 70 percent of the funding, consists
of three separate competitions: (1) The National Clean Diesel Funding
Assistance Program; (2) the National Clean Diesel Emerging Technologies
Program; and (3) the SmartWay Clean Diesel Finance Program. The State
Clean Diesel Grant and Loan Program utilizes the remaining 30 percent
of the funding. In the first year of the program, EPA awarded 119
grants totaling $49.2 million for diesel emissions reduction projects
and programs across the country for cleaner fuels, verified
technologies and certified engine configurations.
Through $300 million in funding provided to the DERA program under
the American Reinvestment and Recovery Act of 2009, EPA will promote
and preserve jobs while improving public health and achieving
significant reductions in diesel emissions.
Furthermore, EPA's National Clean Diesel Campaign, through its
Clean Ports USA program, is working with port authorities, terminal
operators, shipping, truck and rail companies to promote cleaner diesel
technologies and strategies today through education, incentives, and
financial assistance for diesel emissions reductions at ports. Part of
these efforts involves clean diesel programs that can further reduce
emissions from the existing fleet of diesel engines. Finally, many of
the companies operating in states and communities suffering from poor
air quality have voluntarily entered into Memoranda of Understanding
(MOUs) designed to ensure that the cleanest technologies are used first
in regions with the most challenging air quality issues.
In addition to the above innovative programs, we are seeking
comment on a Voluntary Marine Verification Program to address emissions
from existing Category 3 engines. This voluntary program would extend
our existing diesel retrofit verification program to these largest
marine vessels. The concept is described in Section IX.C.3 below.
Taken together, these voluntary approaches can augment the
coordinated strategy and help states and communities achieve larger
reductions sooner in the areas of our country that need them the most.
The Agency remains committed to furthering these programs and others so
that all of our citizens can breathe clean healthy air.
(2) Advanced Emission Technology Solutions are Available
Air pollution from marine diesel exhaust is a challenging problem.
However, we believe it can be addressed effectively through the use of
existing technology to reduce engine-out emissions combined with high-
efficiency catalytic aftertreatment technologies. As discussed in
greater detail in Section III.C, the development of these
aftertreatment technologies for highway and nonroad diesel applications
has advanced rapidly in recent years, so that very large emission
reductions in NOX emissions can be achieved.
Control of NOX emissions from Category 3 engines can be
achieved with high-efficiency exhaust emission control technologies.
Such technologies have already been applied to meet our light-duty
passenger car standards and are expected to be used to meet the
stringent NOX standards included in EPA's heavy-duty highway
diesel, nonroad Tier 4, and locomotive and marine diesel engine
programs. They have been in production for heavy duty trucks in Europe
since 2005, as well as in many stationary source applications
throughout the world. These technologies are discussed further in
Section III.C. While these technologies can be sensitive to sulfur,
their use will be required only in ECAs designated under MARPOL Annex
VI, and they are expected to be able to operate on ECA fuel meeting a
1,000 ppm fuel sulfur. With the lead time available and the assurance
of 1,000 ppm fuel for ocean-going vessels in 2015, as would be required
through ECA designation for U.S. coasts, we are confident the proposed
application of advanced NOX technology to Category 3 marine
engines will proceed at a reasonable rate of progress and will result
in systems capable of achieving the proposed standards on the proposed
schedule. Use of this lower sulfur fuel will also result in substantial
PM emission reductions, since most of the PM emissions from Category 3
engines is due to the use of high sulfur residual fuel.
C. Statutory Basis for Action
Authority for the actions proposed in this documents is granted to
the Environmental Protection Agency by sections 114, 203, 205, 206,
207, 208, 211, 213, 216, and 301(a) of the Clean Air Act as amended in
1990 (42 U.S.C. 7414, 7522, 7524, 7525, 7541, 7542, 7545, 7547, 7550
and 7601(a)), and by sections 1901-1915 of the Act to Prevent Pollution
from Ships (33 U.S.C. 1909 et seq.).
(1) Clean Air Act Basis for Action
EPA is proposing the fuel requirements pursuant to its authority in
section 211 (c) of the Clean Air Act, which allow EPA to regulate fuels
that contribute to air pollution which endangers public health or
welfare (42 U.S.C. 7545(c)). As discussed previously in EPA's Clean Air
Nonroad Diesel rule (69 FR 38958) and below in Section II of this
preamble, the combustion of high sulfur diesel fuel by nonroad,
locomotive, and marine diesel engines contributes to air quality
problems that endanger public health and welfare. Section II also
discusses the significant contribution to these air quality problems by
Category 3 marine vessels. Additional support for the procedural and
enforcement-related aspects of the fuel controls in the proposed rule,
including the record keeping requirements, comes from sections 114(a)
and 301(a) of the CAA (42 U.S.C. Sections 7414 (a) and 7601 (a)).
EPA is proposing emissions standards for new Category 3 marine
diesel engines pursuant to its authority under section 213(a)(3) of the
Clean Air Act, which directs the Administrator to set standards
regulating emissions of NOX, volatile organic compounds
(VOCs), or CO for classes or categories of engines, like marine diesel
engines, that contribute to ozone or carbon monoxide concentrations in
more than one nonattainment area. These ``standards shall achieve the
greatest degree of emission reduction achievable through the
application of technology which the Administrator determines will be
available for the engines or vehicles, giving appropriate consideration
to cost, lead time, noise, energy, and safety factors associated with
the application of such technology.''
EPA is proposing a PM measurement requirement for new Category 3
marine diesel engines pursuant to its authority under section 208,
which requires manufacturers and other persons subject to Title II
requirements to ``provide information the Administrator may reasonably
require * * * to otherwise carry out the provisions of this part* * *''
EPA is also acting under its authority to implement and enforce the
Category 3 marine diesel emissi
