SUPPLEMENTARY INFORMATION: The
public hearing is to provide the public
with an opportunity to present oral
comments regarding EPA’s proposed
action to clarify the obligation to retain
1-hour nonattainment new source
review (NSR) program requirements for
certain areas designated nonattainment
for the 1997 8-hour ozone national
ambient air quality standard (NAAQS).
The EPA has proposed to revise the rule
for implementing the 1997 8-hour ozone
NAAQS to address how NSR
requirements that applied by virtue of
the area’s 1-hour ozone NAAQS
classification should apply under the
VerDate Mar<15>2010
14:31 Sep 17, 2010
Jkt 220001
anti-backsliding provisions of the 1997
8-hour implementation rule. The
proposed rule responds to the ruling by
the U.S. Court of Appeals for the District
of Columbia Circuit that the 1-hour
major NSR program, as it applies to
areas that were designated 1-hour
nonattainment on the date of
designation for the 1997 8-hour
NAAQS, is a required control to prevent
backsliding.
Public hearing: The proposal for
which EPA is holding the public
hearing was published in the Federal
Register on August 24, 2010 (75 FR
51960), and is available at https://
www.epa.gov/nsr and also available in
the docket identified below. The public
hearing will provide interested parties
the opportunity to present data, views,
or arguments concerning the proposal.
The EPA may ask clarifying questions
during the oral presentations, but will
not respond to comments or issues
raised in the presentations at that time.
Written statements and supporting
information submitted during the
comment period will be considered
with the same weight as any oral
comments and supporting information
presented at the public hearing. Written
comments on the proposed rule must be
postmarked by October 1, 2010, which
is the closing date for the comment
period, as specified in the proposal for
the rule. However, the record will
remain open until November 13, 2010,
to allow 30 days after the public hearing
for submittal of additional information
related to the hearing.
The hearing schedule, including a list
of speakers, will be posted on EPA’s
Web site: https://www.epa.gov/nsr.
Verbatim transcripts of the hearings and
written statements will be included in
the docket for the rulemaking.
The EPA will make every effort to
follow the schedule as closely as
possible on the day of the hearings;
however, please plan for the hearing to
run either ahead of schedule or behind
schedule.

I. Background and Purpose
On April 30, 2004, pursuant to the
Federal Clean Air Act (the Act, or CAA),
42 U.S.C. 7401 et seq., EPA designated
portions of the country as being in
nonattainment of the 1997 8-hour ozone
national ambient air quality standard
(NAAQS) (69 FR 23858).1 All parts of
Connecticut, Massachusetts, and Rhode
Island were designated as
nonattainment for ozone, and all were
classified as moderate. There were five
nonattainment areas created that
encompassed the entirety of these states,
as shown in Table 1.

Sections 182(a)(1) and 182(b)(1) of the
CAA compel the preparation and
submittal of an emission inventory by
states containing ozone nonattainment
areas. On November 18, 2002, EPA
issued guidance 2 indicating that 2002
was the preferred year for states to use
as their base year in development of
state implementation plans (SIPs) for
the 1997 8-hour ozone standard.
On November 29, 2005, EPA
published a final rule in the Federal
Register identifying, in part, the
requirements that areas designated
nonattainment for the 1997 8-hour
ozone standard must fulfill in order to
meet their obligations under the Act.
70 FR 71612, codified at 40 CFR part 51
subpart X. This rule is commonly
referred to as the ‘‘Phase 2’’
implementation rule. The Phase 2 rule
provides that areas that had previously
met the CAA section 182(b)(1)
requirement for a 15% volatile organic
compound (VOC) emission reduction
pursuant to the one-hour ozone
standard would be considered to have
met this requirement for the 1997
8-hour standard. According to the Phase
2 rule, such areas must meet reasonable
further progress (RFP) obligations under
the provisions of subpart 1 of the Act,
rather than the more stringent RFP
obligations of subpart 2.
The Phase 2 rule divides the areas
subject to subpart 1 RFP requirements
into two categories: Those with
attainment dates within 5 years of
designation, and those with attainment
dates beyond 5 years from designation.
Connecticut, Massachusetts, and Rhode
Island all fall into the latter category
because their attainment dates were 6
years from the date of designation. The
Phase 2 rule further provides that areas
with an attainment date beyond 5 years
from the date of designation would be
required to meet their RFP requirement
by demonstrating a 15 percent emission
reduction between 2002 and 2008 in
VOC, nitrogen oxide (NOx) or a
combination of both of these pollutants
such that the total reduction in these

ozone precursor emissions equaled 15
percent.3
On February 1, 2008, Connecticut
submitted its 2002 to 2008 RFP plan and
2002 base year inventory to EPA as part
of its attainment demonstration SIP
submittal. Similar submittals were made
by Massachusetts on January 31, 2008,
and by Rhode Island on April 30, 2008.
II. 2002 Base Year Emissions Inventory
A. What is a base year inventory and
why are these states required to prepare
one?
The Act contains a number of
requirements for moderate ozone
nonattainment areas. One requirement,
found at section 182(a)(1) of the Act and
made applicable to moderate ozone
nonattainment areas through section
182(b)(1), compels the preparation and
submittal of a ‘‘comprehensive, accurate,
current inventory of actual emissions
from all sources.’’ As mentioned above,
EPA’s November 18, 2002 guidance
memorandum identified 2002 as the
preferred year for states to use as their
base year in development of SIPs for the
1997 8-hour ozone standard, and the
Phase 2 rule affirms this selection of the
2002 inventory as the baseline for the
RFP requirement.
In August, 2005, EPA published
supplemental guidance for states to use
in development of their base year
inventories entitled, ‘‘Emission
Inventory Guidance for Implementation
of Ozone and Particulate Matter
National Ambient Air Quality Standards
(NAAQS) and Regional Haze
Regulation’’ (EPA–454/R–05–001). This
guidance describes for states the
requirements for development of
comprehensive emission estimates from
stationary point and area sources, and
from mobile on-road and non-road
sources, such that complete emission
inventories are available to support SIP
development for the 8-hour ozone
standard. The guidance directs states to
3 The Phase 2 rule’s application of the CAA’s
VOC percentage reduction requirements was
challenged before the United States Court of
Appeals for the District of Columbia Circuit.
However, the court upheld EPA’s interpretation of
these requirements. See NRDC v. EPA, 571 F.3d
1245 (DC Cir. 2009).

prepare their emission estimates on a
‘‘typical summer day’’ basis to reflect
emissions that occur during high ozone
episodes, which occur predominantly
during the warm summer months.
As mentioned above, Connecticut,
Massachusetts, and Rhode Island all
contain ozone nonattainment areas
designated as moderate for the 1997
8-hour ozone standard. Therefore, they
were required to develop 2002 base year
emission inventories of VOC and NOx,
as these compounds react in the
presence of heat and sunlight to form
ozone.
1. Point Source Emissions
The point source portion of the
inventory consists of emission estimates
for the major industrial facilities within
the state. The emission estimates are
prepared based on facility specific
information collected during annual
surveys conducted by each state’s air
agency. Connecticut and Massachusetts
survey all industrial sources that emit
10 tons/year or more of VOC or NOx.
Rhode Island surveys facilities that emit
10 tons/year or more of VOC, and/or 25
tons/year or more of NOx. The emission
estimates are prepared for each process
operation, fuel combustion process, or
other air emitting activity, then summed
together to obtain an overall emission
estimate for the facility. The states
submit these air emission estimates to
EPA, and we incorporate them into our
national emissions inventory (NEI)
database.
2. Area Source Emissions
Area source emissions include
emissions from small industrial
facilities not included in the point
source inventory, and from sources
whose emissions are, in most
circumstances, spread over a wide
geographic area from a large number of
small sources. Examples include
gasoline service stations, small graphic
arts facilities, landfills, and emissions
from consumer and commercial
products. Emission estimates are made
for most area source categories by
multiplying some indicator of activity
level for the sector, such as gasoline
consumption data for gasoline stations,
E:\FR\FM\20SEP1.SGM
20SEP1
57224
Federal Register / Vol. 75, No. 181 / Monday, September 20, 2010 / Proposed Rules
by emission factors that relate air
emissions to the activity level. The
Connecticut, Massachusetts, and Rhode
Island area source inventories provide
emission estimates for a large number of
source categories, complementing the
emission estimates made for individual
point sources and completing the
estimate of emissions from stationary
sources in the state.
3. On-Road Mobile Source Emissions
Connecticut, Massachusetts, and
Rhode Island all used a highway vehicle
emission estimation model developed
by EPA referred to as the MOBILE 6.2
model to estimate emissions from onroad motor vehicles. Each state obtained
estimates of vehicle miles traveled
(VMT) from their respective
Departments of Transportation. The
states also obtained the information
necessary to run the MOBILE model
accurately for their mix of vehicles, fuel
types, and control programs and used
this information to obtain VOC and NOX
emission estimates from the model.
4. Non-Road Mobile Source Emissions
Connecticut, Massachusetts, and
Rhode Island estimated emissions for
the majority of equipment within the
non-road sector using the EPA’s
NONROAD 2005 model. The
NONROAD model estimates emissions
for diesel, gasoline, liquefied petroleum
gasoline, and compressed natural
gas-fueled non-road equipment types.
The non-road model does not estimate
emissions from aircraft, locomotives, or
commercial marine vessels, and so the
states used other EPA recommended
methods to estimate emissions from
these sectors.

5. Biogenic Emission Sources
Biogenic (naturally occurring)
emissions occur from plants, trees,
grasses and crops. EPA developed a
computer model, referred to as the
Biogenic Emissions Inventory System
(BEIS v. 3.12), to estimate VOC
emissions from this source category, and
calculates biogenic emissions for all
counties in the country. EPA
recommends that states use EPA’s
biogenic emission estimates, and
Connecticut, Massachusetts, and Rhode
Island all relied on EPA’s emission
estimates for this sector.

time period. Section 182(b)(1) of the
CAA required moderate and above
ozone nonattainment areas to develop
plans to reduce VOC emissions by 15
percent over a six year time period
beginning with the date of enactment of
the 1990 amendments to the Act, which
occurred on November 15, 1990. EPA’s
Phase 2 rule interpreted how this
requirement would apply to areas
designated as moderate (or higher)
nonattainment of the 1997 8-hour ozone
standard, and did so in a number of
ways. See 40 CFR part 51 subpart X. Of
relevance for Connecticut,
Massachusetts, and Rhode Island is
what the Phase 2 rule required for areas
with attainment dates greater than 5
years from designation that previously
accomplished a 15% reduction in VOC
emissions pursuant to one-hour ozone
nonattainment requirements, as all three
of these states meet these criteria. For
such areas, the Phase 2 rule indicates
that RFP will be met if the area can
demonstrate a 15% reduction in ozone
precursor emissions (VOC and/or NOX)

will occur between 2002 and 2008.4 See
40 CFR 51.910(b)(2)(ii)(A)–(B). If the
area uses NOX reductions to meet part
or all of this requirement, it must satisfy
EPA guidance concerning the
conditions under which NOX control
may be substituted for, or combined
with, VOC control in order to maximize
the reduction in ozone pollution. The
most current such guidance is EPA’s
December 1993 ‘‘NOX Substitution
Guidance.’’ Therefore, the RFP plans
submitted by Connecticut,
Massachusetts, and Rhode Island were
evaluated against these criteria. These
states prepared RFP plans for each of
the nonattainment areas shown in Table
1 above. We note that Connecticut’s
plan for the NY–NJ–CT area only
accounts for emission reductions from
within the Connecticut portion of the
area.
As noted above, Connecticut,
Massachusetts, and Rhode Island
submitted final, adopted RFP plans to
EPA between January 31 and April 30,
2008. Although the Phase 2 rule
required that these plans be submitted
by June 15, 2007, the states submitted
draft plans to EPA shortly after the due
date, and as discussed in this document
the plans meet EPA’s approval
requirements for RFP plans developed
to help meet the 1997 8-hour ozone
NAAQS.
Each of these state’s RFP plans rely to
some degree on NOX emission
reductions to achieve the overall 15
percent reduction in ozone precursor
emissions. Available modeling indicates
that NOX emission reductions are
clearly beneficial in Connecticut,
Massachusetts, and Rhode Island, and
so as outlined in EPA’s NOX
Substitution Guidance, use of NOX
emission reductions to meet RFP
requirements is appropriate.
The manner in which states are to
determine the required level of emission
reductions is similar to the procedure
explained in the guidance document
entitled, ‘‘Guidance on the Adjusted
Base Year Emissions Inventory and the
1996 Target for the 15% Rate of Progress
Plans’’ (EPA–452/R–92–005).
Adjustments to this procedure
pertaining to proper accounting of the
non-creditable emission reductions from
the pre-1990 Federal motor vehicle
control program (FMVCP) are noted
within Appendix A of the Phase 2 rule
(70 FR 71696, as corrected by 71 FR
58498).
B. What action is EPA taking on these
plans?
We are proposing approval of the RFP
plans submitted by Connecticut,
Massachusetts, and Rhode Island for the
moderate nonattainment areas shown in
Table 1 above, as revisions to these
states’ implementation plans. Note that
regarding the NY–NJ–CT moderate area,
57225
we are proposing action today only on
the Connecticut portion of the RFP plan.
C. What emission levels must
Connecticut, Massachusetts, and Rhode
Island achieve by 2008?
Tables 3a–3e below contain a
summary of the RFP calculations as
performed by Connecticut,
Massachusetts, and Rhode Island for
their moderate ozone nonattainment
areas. Some of the 2002 base year
inventory values shown in Step 1 of
Tables 3a–3e are slightly higher than
those shown in Tables 2a–2e due to
adjustments each state made to their
RFP SIPs to account for emissions
banking and trading programs. These
adjustments are described elsewhere in
this proposal. The emission target levels
are shown in step 6 of Tables 3a–3e. The
emission targets represent the maximum
amount of emissions that can occur in
2008 given the state’s selected mix of
VOC and NOX percent reductions as
noted in step 4 of the calculations. The
RFP plans submitted by Connecticut,
Massachusetts, and Rhode Island
indicate that the projected, controlled
emissions for 2008 shown in Step 7 of
Tables 3a–3e are below the 2008
emission target levels shown in step 6,
with the exception of Rhode Island’s
VOC emissions. To remedy this small
shortfall, Rhode Island allocated surplus
NOX emissions reductions that were
available as shown in Table 3e.

Rhode Island allocated an additional

to 1.1 tons) to cover this shortfall. Thus,
Rhode Island has set its 2008 NOX target
to 57.8 tons/day rather than 58.9 tons/
day. In essence, Rhode Island has
selected a 16.6% reduction in NOX
emissions and a 1.5% increase in VOC
emissions, resulting in a combined
reduction of 15.1%.

EPA’s guidance to states on the
development of RFP plans does not
directly address the situation found in
Rhode Island’s RFP plan, where surplus
reductions for one ozone precursor were
used to cover an increase in emissions
for the other precursor. For example,
EPA’s Phase 2 implementation rule
provides that moderate areas such as
Rhode Island with attainment dates
more than 5 years from the date of
designation, ‘‘(A) Shall provide for a 15
percent emission reduction from the
baseline year within 6 years after the
baseline year. (B) May use either NOX or
VOC emissions reductions (or both) to
achieve the 15 percent emission
reduction requirement. Use of NOX

Frm 00033

NOX emissions
(tons/day)
emissions reductions must meet the
criteria in section 182(c)(2)(C) of the
Act.’’ 40 CFR 51.910(b)(2)(ii). EPA’s NOX
Substitution Guidance, which EPA
issued pursuant to section 182(c)(2)(C),
does not specifically address offsetting
an increase in one precursor with
surplus reductions from another
precursor. Thus, we reviewed the facts
of this specific case and, as explained
below, have determined that the
submitted plan is consistent with the
CAA requirements.
First, EPA’s December 1993 NOX
substitution guidance provides the
criteria that must be met in order for
NOX emission reductions to be used in
RFP plans as provided by section
E:\FR\FM\20SEP1.SGM
20SEP1
jdjones on DSK8KYBLC1PROD with PROPOSALS-1
Federal Register / Vol. 75, No. 181 / Monday, September 20, 2010 / Proposed Rules
182(c)(2)(C) of the Act. The guidance
directs states to ensure that such
substitution is done only to the extent
that the modeled attainment
demonstration for the area indicates that
this substitution is appropriate. For
example, section 2 of the guidance
provides that, ‘‘This linkage provides
assurance that the RFP reductions are
consistent with the SIP attainment
demonstration. States are required to
justify substitution by illustrating
‘‘consistency’’ between the cumulative
emission changes emerging from the
RFP/substitution proposal and the
emission reductions in the modeled
attainment demonstration.’’
Rhode Island worked in conjunction
with the other states within the ozone
transport region (OTR) to perform the
urban airshed modeling that the state
included within its attainment
demonstration, and on development of
recommended control strategies to
reduce VOC and NOX emissions in the
Northeast such that the ozone NAAQS
would be met by 2009. This modeling
exercise showed that both VOC and
NOX emission reductions would be
needed to reach the area’s attainment
goals. The resulting suite of federal and
state control measures indicate that NOX
emission reductions figured
prominently in the area’s attainment
strategy. This is most clearly seen by the
fact that NOX emissions were projected
to decline by a greater extent than VOC
emissions between the base year and
attainment year across the OTR. This
illustrates that Rhode Island’s use of
NOX emission reductions within its RFP
plan is appropriate.
Second, the increase in VOC
emissions between 2002 and 2008 is an
artifact of EPA’s RFP calculation
procedure; the state’s actual VOC
emissions in 2008 were predicted to be
lower than they were in 2002. In
explanation, as shown in step 2 of Table
3e above, Rhode Island’s 2002
anthropogenic VOC emissions were
119.2 tons per summer day (tpsd).
However, EPA’s RFP calculation
procedure requires that emission
reductions from the pre-1990 federal
motor vehicle control program (FMVCP)
that will accrue between 2002 and 2008
be subtracted from the 2002
anthropogenic baseline because the Act,
at section 182(b)(1)(D)(i), provides such
reductions are not creditable for
purposes of meeting RFP requirements.
This subtraction is shown in step 3 of
Table 3e above, and resulted in the 2002
baseline being lowered by 5.5 tpsd to
113.7 tpsd. Since no VOC reductions
were planned for in the RFP plan, 113.7
tpsd is also the state’s target level of
emissions for VOCs. As shown in step
VerDate Mar<15>2010
14:31 Sep 17, 2010
Jkt 220001
7 of Table 3e, Rhode Island’s 2008 VOC
emissions were estimated to be 115.4
tpsd. This is higher than the VOC target
emission level of 113.7 tpsd by 1.7 tpsd,
but is lower than the state’s actual 2002
anthropogenic baseline emissions of
119.2 tpsd by 3.8 tpsd. The preceding
comparison is not intended to diminish
the significance of the Act’s prohibition
against crediting reductions due to the
pre-1990 FMVCP towards RFP. Rather,
this analysis simply clarifies that this is
not a situation where a state proposes to
rely on a larger-than-15% decrease in
NOX emissions to offset an actual
increase in VOC emissions; rather, here
Rhode Island has in fact reduced its
VOC emissions from the baseline.
Third, in 2009, Rhode Island adopted
and implemented VOC control measures
on consumer and commercial products
and architectural and industrial
maintenance coatings. The effective date
for these two rules was June 4, 2009,
and since the RFP plan covers the time
period between 2003 to 2008 Rhode
Island did not factor reductions from
these rules into their RFP analysis.
However, these rules are now in effect
and are currently acting to lower VOC
emissions beyond that shown in the
RFP analysis. Thus, while Rhode Island
could not take credit for these emission
reductions as part of the RFP plan for
2003 to 2008, additional reductions in
VOC emissions have occurred in the
state since then.
Last, but by no means of least
importance, Rhode Island is currently in
attainment of the 1997 8-hour ozone
standard, and EPA published a clean
data determination for the area on June
3, 2010 (75 FR 31288). In addition, on
July 28, 2010 (75 FR 44179), EPA
published a notice of proposed
rulemaking indicating that this area
attained the 1997 8-hour ozone standard
by its attainment date of June 15, 2010.
Thus, our primary basis for approving
the RFP plan is to approve the 2008
motor vehicle emission budgets
contained within the plan as the plan is
not necessary to ensure that the state
makes reasonable further progress
towards the 1997 standard it has already
attained.
In light of these circumstances, EPA
has determined that it is appropriate to
propose approval of Rhode Island’s RFP
plan.
D. To what extent do the RFP plans
reduce ozone precursor emissions?
The Connecticut, Massachusetts, and
Rhode Island RFP plans indicate that
ozone precursor emissions will be
substantially reduced between 2002 and
2008, allowing each state to exceed the
15% ozone precursor emission
PO 00000
Frm 00034
Fmt 4702
Sfmt 4702
57227
reduction obligation over this time
frame. Compared to 2002 emission
levels, the RFP plans and associated
modeling showed that VOC emissions
were expected to decline by 19% in
Connecticut, 16% in Massachusetts, and
3% in Rhode Island by 2008.
Additionally, NOX emissions were
expected to decline by 25% in
Connecticut, 37% in Massachusetts, and
24% in Rhode Island over this
timeframe. These percent reductions
include reductions from the pre-1990
FMVCP program shown in step 3 of
Tables 3a–3e.
E. Are banked emissions properly
accounted for within these RFP plans?
Although the initial RFP plan
submittals made by Connecticut,
Massachusetts, and Rhode Island did
not account for banked emissions, each
state made subsequent amendments to
their plans that incorporated banked
emissions into the RFP analysis.
Many states operate emissions
banking and trading programs. These
programs allow facilities that agree to
permanently cease, or alternatively
agree to permanently reduce their
emissions to levels below allowable
levels, to generate emission reduction
credits (ERCs) that can be sold or traded
to other facilities. ERCs are often
purchased by facilities seeking emission
offsets to meet the requirements of the
new source review (NSR) program. State
air agencies facilitate and monitor these
transactions by creating and
maintaining an emissions bank where
ERCs are stored until they are
purchased. Since ERCs represent
emissions that may occur at some point
in the future, and RFP plans contain
both base year and future year emission
estimates as well as maximum allowable
(target level) emissions for the
nonattainment area as a whole, banked
emissions need to be accounted for in a
state’s RFP analysis.
On October 14, 2009, Connecticut
submitted a revision to the RFP plan
which it had originally submitted to
EPA on February 1, 2008. The revision
consisted of the incorporation of a small
number of banked NOX ERCs into the
state’s RFP analysis. The inclusion of
the banked ERCs into the RFP analysis
did not alter the state’s conclusion that
it easily meets RFP requirements. The
emission estimates within Tables 3a and
3b above reflect the revised calculations
contained within Connecticut’s October
14, 2009 submittal to EPA.
On October 23, 2009, Massachusetts
submitted a revision to the RFP plan
which it had originally submitted to
EPA on January 31, 2008. The revision
consisted of the incorporation of a small

jdjones on DSK8KYBLC1PROD with PROPOSALS-1
amount of banked VOC, and a larger
amount of banked NOX ERCs into the
state’s RFP analysis. As with
Connecticut, the inclusion of
Massachusetts’ banked ERCs into the
RFP analysis did not change the state’s
conclusion that it readily meets RFP.
Tables 3c and 3d above contains the
revised RFP calculations contained
within Massachusetts’ October 23, 2009
submittal.
On October 19, 2009, Rhode Island
submitted a revision to the RFP plan
which it had submitted to EPA on April
30, 2008. The revision consisted of the
incorporation of banked VOC ERCs into
the state’s RFP analysis. As with the
above mentioned submittals from
Connecticut and Massachusetts, Rhode
Island’s revised plan continues to show
that the state meets its RFP emission
reduction obligations, and these revised
estimates are reflected in Table 3e
above.
F. What are the pollution control
programs that accomplish this change
in emissions?
Many post-1990 Federal mobile
source control programs which are
creditable towards meeting RFP took
effect between 2002 and 2008, and they
are responsible for the bulk of the VOC
and NOX emission reductions that
occurred over this time frame in
Connecticut, Massachusetts, and Rhode
Island. For example, within the on-road
mobile sector the Federal Tier 2 motor
vehicle control program and controls for
heavy duty diesel vehicles and fuels
were significant programs that helped to
reduce emissions during this period of
time. Within the non-road sector,
Federal controls on diesel engines and
the Phase 2 standards for gasoline
powered handheld and non-handheld
equipment began, which helped reduce
emissions from that sector.
In addition to Federal measures for
mobile source emissions, state-adopted
control measures also acted to reduce
VOC and NOX emissions between 2002
and 2008. In Connecticut, state-adopted
rules limiting emissions from portable
fuel containers, architectural and
industrial maintenance (AIM) coatings,
pressure-vacuum (PV) valves at gasoline
service stations, and requirements for
solvent cleaning fluids were adopted
between 2002 and 2008, and will help
to reduce VOC emissions in the state.
The portable fuel container and PV
valves at gasoline station rules have
been approved by EPA into the state’s
SIP. (See 71 FR 51761). The AIM and
solvent cleaning rules have not yet been
approved by EPA into the State’s SIP,
but we are proposing approval of them
in other parts of this document and
VerDate Mar<15>2010
14:31 Sep 17, 2010
Jkt 220001
intend to approve them prior to, or in
conjunction with, our final rulemaking
action on Connecticut’s RFP plan.
Additionally, in May of 2003, Phase 2
of the state’s limits for emissions from
municipal waste combustors began, and
this program will reduce NOX emissions
from that sector. This program has also
been approved into the state’s SIP. (See
66 FR 63311).
Connecticut’s NOX budget program
began in 2002 and so emission
reductions from the program are
reflected in the state’s 2002 base year
inventory. Connecticut’s Clean Air
Interstate Rule (CAIR) rule has taken the
place of its NOX budget program
beginning in 2009. On July 11, 2008, the
United States Court of Appeals for the
District of Columbia issued an opinion
vacating and remanding EPA’s CAIR
rule. See North Carolina v EPA, 531
F.3d 896 (DC Cir. 2008). However, on
December 23, 2008, the court granted
rehearing in part and remanded the rule
back to EPA for revision without
vacatur. 550 F.3d 1176 (DC Cir. 2008).
Accordingly, CAIR is to be implemented
as it was originally intended until EPA
revises the rule to address the court’s
remand.6 Therefore, the NOX reductions
achieved by Connecticut’s NOX budget
program continue as the state has
transitioned to its CAIR program.
Connecticut’s CAIR program was
approved by EPA on January 24, 2008
(73 FR 4105).
For the on-road mobile sector, in
2004, Connecticut adopted an enhanced
motor vehicle inspection and
maintenance (I&M) program including
on-board diagnostics (OBD–2)
requirements. EPA approved
Connecticut’s I&M program with OBD–
2 requirements into the state’s SIP on
December 5, 2008 (73 FR 74019).
Massachusetts claimed emission
reduction credit within its RFP plan for
the NOX emission reductions achieved
by the state’s NOX SIP Call Trading
program, as that program’s
implementation date was in 2003.
Massachusetts submitted its ‘‘NOX
Allowance Trading Program’’ (also
referred to as the NOX Budget or the
NOX SIP Call trading program) to EPA
as a SIP revision request, and EPA
approved the rule into the
Commonwealth’s SIP. Amendments to
the rule were incorporated into the
state’s SIP on December 3, 2007. (72 FR
67854). EPA’s December 3, 2007 action
also approved the Commonwealth’s
CAIR, which replaced the state’s NOX
Budget program beginning in 2009.
6 On August 2, 2010 (75 FR 45210), EPA proposed
the Transport Rule to address the flaws in CAIR
noted by the Court.

Frm 00035
Fmt 4702
Sfmt 4702
Therefore, NOX emissions from sources
covered by the Commonwealth’s NOX
Allowance trading program will remain
constrained after 2008 as the state
implements its CAIR control program.
Massachusetts expects to reduce onroad mobile source emissions by its
state-run Low Emissions Vehicle (LEV)
program. Massachusetts submitted the
adopted LEV program to EPA, and EPA
approved it into the state’s SIP on
December 23, 2002 (67 FR 78179).
At the time Rhode Island developed
its RFP SIP, it was in the process of
adopting a number of control measures
for stationary sources of VOC emissions
that were set to take effect in 2009, and
so emission reductions from these
measures were not incorporated into the
state’s RFP plan because measures in
such plans need to have an impact by
2008. Rhode Island was not required to
participate in EPA’s CAIR program.
Accordingly, Rhode Island’s RFP plan
shows that it meets the 15% emission
reduction obligation by relying
exclusively on emission reductions
between 2002 and 2008 in the mobile
source sector. Additionally, the state
shows that it can meet its obligation by
relying only upon NOX emission
reductions. These emission reductions
occur as a result of the post-1990
Federal mobile source control measures,
as mentioned above, the state’s adoption
of a motor vehicle I&M Program, and the
state-adopted Low Emissions Vehicle
program. EPA has approved both of
these programs into the Rhode Island
SIP. (See 66 FR 9661, and 65 FR 12476,
respectively.)
G. Is EPA proposing approval of any
state control measures in this action?
We are proposing to approve three
VOC control measures from
Connecticut, two of which were
included in the state’s February 1, 2008
SIP submittal to EPA. These rules
consist of a solvent metal cleaning rule,
an architectural and industrial
maintenance (AIM) coatings rule, and
an asphalt paving rule submitted on
January 8, 2009. The solvent metal
cleaning and AIM coatings rules have
compliance dates in May of 2008, and
so achieve emission reductions that
help Connecticut demonstrate
compliance with its RFP obligation. The
asphalt paving rule has a May 1, 2009
compliance date and was submitted to
help the state demonstrate that it meets
the Clean Air Act section 182(b)(2)
requirement that sources in the state use
reasonably available control technology
(RACT) to control air pollution. We are
not proposing action on Connecticut’s
overall RACM or RACT submittals at

this time. Additional information about
each of these rules is provided below.
Metal cleaning rule. Connecticut’s
February 1, 2008 SIP submittal to EPA
included an amendment to its existing
SIP approved metal cleaning rule,
located at section 22a–174–20 of the
Regulations of Connecticut State
Agencies (‘‘Control of organic compound
emissions, loading of gasoline and other
volatile organic compounds’’), paragraph
(l) (‘‘Metal cleaning’’). The amended rule
adds a limit on the vapor pressure of
solvents used in cold cleaning and other
requirements to further limit emissions
of VOCs from metal cleaning operations.
These requirements are consistent with
the Ozone Transport Commission’s
(OTC’s) 2001 model rule for solvent
cleaning. The compliance date for the
rule was May 1, 2008.
AIM coatings rule. Connecticut’s
February 1, 2008 SIP submittal included
a new rule, section 22a–174–41
(‘‘Architectural and industrial
maintenance coatings’’), that limits VOC
emissions from AIM coatings. The
state’s rule establishes VOC content
limits consistent with those developed
in 2001 within a model rule created by
the OTC. The limits in the state’s rule
are as stringent as, or more stringent
than, those contained in the Federal
AIM rule adopted by EPA in December
1998 (40 CFR part 59, subpart D). The
compliance date for most of the
regulated product categories was May 1,
2008. EPA notes that we are relying on
the federal enforceability of section
(g)(3)(A)(iii) referenced in that section of
the rule.
Asphalt paving rule. On January 8,
2009, Connecticut submitted an
amendment to its existing SIP-approved
section 22a–174–20 (‘‘Control of organic
compound emissions, loading of
gasoline and other volatile organic
compounds’’), paragraph (k)
(‘‘Restrictions on VOC emissions from
cutback and emulsified asphalt’’). The
amended regulation includes a seasonal
ban on the use of cutback asphalt and
a reduction in the acceptable VOC
content of emulsified asphalt. The
compliance date for the rule was May 1,
2009.
Connecticut held a public hearing on
the first two rules mentioned above on
June 27, 2006, and held a hearing on the
asphalt paving rule on May 1, 2007.
EPA reviewed draft versions of these
rules and provided comments to
Connecticut during the public hearing
process, and Connecticut responded
adequately to our comments. We are
proposing approval of Connecticut’s
revised solvent metal cleaning and
asphalt paving rules, and its new AIM
coatings rule, so that they may become

part of the state’s federally enforceable
SIP.
H. Have these states met their
contingency measure obligation?
Section 172(c)(9) of the CAA requires,
in part, that nonattainment areas
provide for contingency measures ‘‘to be
undertaken if the area fails to make
reasonable further progress, or to attain
the national primary ambient air quality
standard by the attainment date
applicable under this part.’’ EPA has
long interpreted the Act to require that
contingency measures must provide
reductions of 3 percent of the emissions
from the adjusted base year inventory
(57 FR 13498, 13510–13511). States may
choose to meet this requirement by
consuming surplus emission reductions
shown in their RFP target level
calculations, if a surplus exists.
However, pursuant to a guidance
memorandum issued by EPA on
November 8, 1993,7 any measures that
are already required are not creditable
as contingency measures. Connecticut,
Massachusetts, and Rhode Island each
chose to meet the contingency
obligation using surplus emission
reductions as noted in the target level
calculations.
Connecticut and Massachusetts can
both readily show that ample surplus
emission reductions exist, and that they
have implemented controls not
otherwise required. In Connecticut’s
case, 2008 VOC emissions are projected
to be 5.7% lower than the target, and
NOX emissions 16.5% lower than the
target in the Greater Connecticut area.
For the Connecticut portion of the NY–
NJ–CT area, these surpluses are 8.3% for
VOC, and 14.5% for NOX. Connecticut
has adopted a number of rules that are
not otherwise required by the CAA that
it could count towards its contingency
obligation, such as its AIM coatings,
automobile refinishing, and solvent
cleaning rules. For Massachusetts, 2008
VOC emissions are projected to be
10.6% lower than the target, and NOX
emissions 22.6% lower in the Eastern
Massachusetts area. For the Western
Massachusetts area, these surpluses are
10.8% for VOC, and 27.6% for NOX.
The state’s low emission vehicle
program, which achieves both VOC and
NOX emission reductions, is an example
of a rule the state adopted that was not
otherwise required by the CAA.
Rhode Island projects that it will have
a 3.6% NOX surplus that it claims can
be devoted towards meeting the RFP

Areas.’’

contingency requirement. Given the
state’s reliance on Federal measures to
reduce emissions between 2002 and
2008, the state has not demonstrated
that it can meet the contingency
requirement via reductions from
already-adopted NOX rules not
otherwise required by the CAA.
However, Rhode Island could remedy
this by relying on the additional VOC
control programs for stationary sources
that it adopted in 2009, which included
rules establishing emission limits for
consumer and commercial products,
and on architectural and industrial
maintenance coatings. A public hearing
on these proposed rules was held on
February 20, 2009, and they were
promulgated as final state regulations
May 15, 2009, with an effective date of
June 4, 2009. Rhode Island submitted
these regulations to EPA as SIP
revisions, but EPA has not yet approved
into the Rhode Island SIP. Section 8.3
of Rhode Island’s attainment
demonstration submittal alludes to the
possibility of using reductions from
these measures as an alternative means
of meeting the RFP contingency
obligation. We are therefore proposing
to approve use of emission reductions
from these stationary source measures
(which, as noted above, have taken
effect under state law but have not yet
been approved into Rhode Island’s SIP)
as meeting the state’s contingency plan
requirement. Section 8.3 of Rhode
Island’s attainment demonstration
submittal stated that reductions from
these regulations were expected to
reduce VOC emissions by 2009 by 5.0
tons/day. This would cover the 3%
contingency obligation, as 3% of the
state’s 2002 RFP inventory for VOCs,
which is 119.2 tons/day, equals 3.6
tons/day. EPA would need to approve
these two rules into Rhode Island’s SIP
prior to, or in conjunction with, our
taking final action on the state’s RFP
plan.
I. Are transportation conformity budgets
contained in these plans?
Section 176(c) of the CAA, and EPA’s
transportation conformity rule at 40 CFR
part 93 subpart A, require that
transportation plans, programs, and
projects conform to state air quality
implementation plans. Conformity to a
SIP means that transportation activities
will not cause or contribute to new air
quality violations, worsen existing
violations, or delay timely attainment of
the NAAQS. States are required to
establish motor vehicle emission
budgets in any control strategy SIP that
is submitted for attainment and
maintenance of the NAAQS. The RFP
plans submitted by Connecticut,

approval of these states' 2002 base year inventories and reasonable
further progress (RFP) emission reduction plans, and to propose
approval of the 2008 motor vehicle transportation budgets and
contingency measures associated with the RFP plans. EPA also proposes
approval of three rules adopted by Connecticut that will reduce
volatile organic compound emissions in the state.

I. Background and Purpose
On April 30, 2004, pursuant to the Federal Clean Air Act (the Act,
or CAA), 42 U.S.C. 7401 et seq., EPA designated portions of the country
as being in nonattainment of the 1997 8-hour ozone national ambient air
quality standard (NAAQS) (69 FR 23858).\1\ All parts of Connecticut,
Massachusetts, and Rhode Island were designated as nonattainment for
ozone, and all were classified as moderate. There were five
nonattainment areas created that encompassed the entirety of these
states, as shown in Table 1.
---------------------------------------------------------------------------
\1\ The 1997 8-hour ozone standard itself is codified at 40 CFR
50.10.

Sections 182(a)(1) and 182(b)(1) of the CAA compel the preparation
and submittal of an emission inventory by states containing ozone
nonattainment areas. On November 18, 2002, EPA issued guidance \2\
indicating that 2002 was the preferred year for states to use as their
base year in development of state implementation plans (SIPs) for the
1997 8-hour ozone standard.
---------------------------------------------------------------------------
\2\ ``2002 Base Year Emission Inventory SIP Planning: 8-hr
Ozone, PM 2.5, and Regional Haze Programs.''
---------------------------------------------------------------------------
On November 29, 2005, EPA published a final rule in the Federal
Register identifying, in part, the requirements that areas designated
nonattainment for the 1997 8-hour ozone standard must fulfill in order
to meet their obligations under the Act. 70 FR 71612, codified at 40
CFR part 51 subpart X. This rule is commonly referred to as the ``Phase
2'' implementation rule. The Phase 2 rule provides that areas that had
previously met the CAA section 182(b)(1) requirement for a 15% volatile
organic compound (VOC) emission reduction pursuant to the one-hour
ozone standard would be considered to have met this requirement for the
1997 8-hour standard. According to the Phase 2 rule, such areas must
meet reasonable further progress (RFP) obligations under the provisions
of subpart 1 of the Act, rather than the more stringent RFP obligations
of subpart 2.
The Phase 2 rule divides the areas subject to subpart 1 RFP
requirements into two categories: Those with attainment dates within 5
years of designation, and those with attainment dates beyond 5 years
from designation. Connecticut, Massachusetts, and Rhode Island all fall
into the latter category because their attainment dates were 6 years
from the date of designation. The Phase 2 rule further provides that
areas with an attainment date beyond 5 years from the date of
designation would be required to meet their RFP requirement by
demonstrating a 15 percent emission reduction between 2002 and 2008 in
VOC, nitrogen oxide (NOx) or a combination of both of these pollutants
such that the total reduction in these ozone precursor emissions
equaled 15 percent.\3\
---------------------------------------------------------------------------
\3\ The Phase 2 rule's application of the CAA's VOC percentage
reduction requirements was challenged before the United States Court
of Appeals for the District of Columbia Circuit. However, the court
upheld EPA's interpretation of these requirements. See NRDC v. EPA,
571 F.3d 1245 (DC Cir. 2009).
---------------------------------------------------------------------------
On February 1, 2008, Connecticut submitted its 2002 to 2008 RFP
plan and 2002 base year inventory to EPA as part of its attainment
demonstration SIP submittal. Similar submittals were made by
Massachusetts on January 31, 2008, and by Rhode Island on April 30,
2008.
II. 2002 Base Year Emissions Inventory
A. What is a base year inventory and why are these states required to
prepare one?
The Act contains a number of requirements for moderate ozone
nonattainment areas. One requirement, found at section 182(a)(1) of the
Act and made applicable to moderate ozone nonattainment areas through
section 182(b)(1), compels the preparation and submittal of a
``comprehensive, accurate, current inventory of actual emissions from
all sources.'' As mentioned above, EPA's November 18, 2002 guidance
memorandum identified 2002 as the preferred year for states to use as
their base year in development of SIPs for the 1997 8-hour ozone
standard, and the Phase 2 rule affirms this selection of the 2002
inventory as the baseline for the RFP requirement.
In August, 2005, EPA published supplemental guidance for states to
use in development of their base year inventories entitled, ``Emission
Inventory Guidance for Implementation of Ozone and Particulate Matter
National Ambient Air Quality Standards (NAAQS) and Regional Haze
Regulation'' (EPA-454/R-05-001). This guidance describes for states the
requirements for development of comprehensive emission estimates from
stationary point and area sources, and from mobile on-road and non-road
sources, such that complete emission inventories are available to
support SIP development for the 8-hour ozone standard. The guidance
directs states to prepare their emission estimates on a ``typical
summer day'' basis to reflect emissions that occur during high ozone
episodes, which occur predominantly during the warm summer months.
As mentioned above, Connecticut, Massachusetts, and Rhode Island
all contain ozone nonattainment areas designated as moderate for the
1997 8-hour ozone standard. Therefore, they were required to develop
2002 base year emission inventories of VOC and NOx, as these compounds
react in the presence of heat and sunlight to form ozone.
1. Point Source Emissions
The point source portion of the inventory consists of emission
estimates for the major industrial facilities within the state. The
emission estimates are prepared based on facility specific information
collected during annual surveys conducted by each state's air agency.
Connecticut and Massachusetts survey all industrial sources that emit
10 tons/year or more of VOC or NOx. Rhode Island surveys facilities
that emit 10 tons/year or more of VOC, and/or 25 tons/year or more of
NOx. The emission estimates are prepared for each process operation,
fuel combustion process, or other air emitting activity, then summed
together to obtain an overall emission estimate for the facility. The
states submit these air emission estimates to EPA, and we incorporate
them into our national emissions inventory (NEI) database.
2. Area Source Emissions
Area source emissions include emissions from small industrial
facilities not included in the point source inventory, and from sources
whose emissions are, in most circumstances, spread over a wide
geographic area from a large number of small sources. Examples include
gasoline service stations, small graphic arts facilities, landfills,
and emissions from consumer and commercial products. Emission estimates
are made for most area source categories by multiplying some indicator
of activity level for the sector, such as gasoline consumption data for
gasoline stations,
[[Page 57224]]
by emission factors that relate air emissions to the activity level.
The Connecticut, Massachusetts, and Rhode Island area source
inventories provide emission estimates for a large number of source
categories, complementing the emission estimates made for individual
point sources and completing the estimate of emissions from stationary
sources in the state.
3. On-Road Mobile Source Emissions
Connecticut, Massachusetts, and Rhode Island all used a highway
vehicle emission estimation model developed by EPA referred to as the
MOBILE 6.2 model to estimate emissions from on-road motor vehicles.
Each state obtained estimates of vehicle miles traveled (VMT) from
their respective Departments of Transportation. The states also
obtained the information necessary to run the MOBILE model accurately
for their mix of vehicles, fuel types, and control programs and used
this information to obtain VOC and NOX emission estimates
from the model.
4. Non-Road Mobile Source Emissions
Connecticut, Massachusetts, and Rhode Island estimated emissions
for the majority of equipment within the non-road sector using the
EPA's NONROAD 2005 model. The NONROAD model estimates emissions for
diesel, gasoline, liquefied petroleum gasoline, and compressed natural
gas-fueled non-road equipment types. The non-road model does not
estimate emissions from aircraft, locomotives, or commercial marine
vessels, and so the states used other EPA recommended methods to
estimate emissions from these sectors.
5. Biogenic Emission Sources
Biogenic (naturally occurring) emissions occur from plants, trees,
grasses and crops. EPA developed a computer model, referred to as the
Biogenic Emissions Inventory System (BEIS v. 3.12), to estimate VOC
emissions from this source category, and calculates biogenic emissions
for all counties in the country. EPA recommends that states use EPA's
biogenic emission estimates, and Connecticut, Massachusetts, and Rhode
Island all relied on EPA's emission estimates for this sector.
B. Summary of 2002 Base Year Inventories
The 2002 VOC and NOX base year inventories prepared by
Connecticut, Massachusetts, and Rhode Island are shown below in Tables
2a through 2e. EPA has concluded that these states have adequately
derived and documented the 2002 base year VOC and NOX
emissions for these areas.

C. What action is EPA taking on these inventories?
We are proposing approval of the 2002 base year inventories listed
in Tables 2a through 2e above.
III. Reasonable Further Progress Plans
A. What is a reasonable further progress plan, and why are these states
required to prepare one?
A reasonable further progress (RFP) plan illustrates how an ozone
nonattainment area will make emission reductions of a set amount over a
given time period. Section 182(b)(1) of the CAA required moderate and
above ozone nonattainment areas to develop plans to reduce VOC
emissions by 15 percent over a six year time period beginning with the
date of enactment of the 1990 amendments to the Act, which occurred on
November 15, 1990. EPA's Phase 2 rule interpreted how this requirement
would apply to areas designated as moderate (or higher) nonattainment
of the 1997 8-hour ozone standard, and did so in a number of ways. See
40 CFR part 51 subpart X. Of relevance for Connecticut, Massachusetts,
and Rhode Island is what the Phase 2 rule required for areas with
attainment dates greater than 5 years from designation that previously
accomplished a 15% reduction in VOC emissions pursuant to one-hour
ozone nonattainment requirements, as all three of these states meet
these criteria. For such areas, the Phase 2 rule indicates that RFP
will be met if the area can demonstrate a 15% reduction in ozone
precursor emissions (VOC and/or NOX)
[[Page 57225]]
will occur between 2002 and 2008.\4\ See 40 CFR 51.910(b)(2)(ii)(A)-
(B). If the area uses NOX reductions to meet part or all of
this requirement, it must satisfy EPA guidance concerning the
conditions under which NOX control may be substituted for,
or combined with, VOC control in order to maximize the reduction in
ozone pollution. The most current such guidance is EPA's December 1993
``NOX Substitution Guidance.'' Therefore, the RFP plans
submitted by Connecticut, Massachusetts, and Rhode Island were
evaluated against these criteria. These states prepared RFP plans for
each of the nonattainment areas shown in Table 1 above. We note that
Connecticut's plan for the NY-NJ-CT area only accounts for emission
reductions from within the Connecticut portion of the area.
---------------------------------------------------------------------------
\4\ If the area wishes to use NOX reductions to meet
part or all of this 15% requirement, the calculation is not done by
measuring the overall percent of combined VOC and NOX
reductions, but rather by separately calculating the percent of VOC
reductions and the percent of NOX reductions, and adding
those percentages together.
---------------------------------------------------------------------------
As noted above, Connecticut, Massachusetts, and Rhode Island
submitted final, adopted RFP plans to EPA between January 31 and April
30, 2008. Although the Phase 2 rule required that these plans be
submitted by June 15, 2007, the states submitted draft plans to EPA
shortly after the due date, and as discussed in this document the plans
meet EPA's approval requirements for RFP plans developed to help meet
the 1997 8-hour ozone NAAQS.
Each of these state's RFP plans rely to some degree on
NOX emission reductions to achieve the overall 15 percent
reduction in ozone precursor emissions. Available modeling indicates
that NOX emission reductions are clearly beneficial in
Connecticut, Massachusetts, and Rhode Island, and so as outlined in
EPA's NOX Substitution Guidance, use of NOX
emission reductions to meet RFP requirements is appropriate.
The manner in which states are to determine the required level of
emission reductions is similar to the procedure explained in the
guidance document entitled, ``Guidance on the Adjusted Base Year
Emissions Inventory and the 1996 Target for the 15% Rate of Progress
Plans'' (EPA-452/R-92-005). Adjustments to this procedure pertaining to
proper accounting of the non-creditable emission reductions from the
pre-1990 Federal motor vehicle control program (FMVCP) are noted within
Appendix A of the Phase 2 rule (70 FR 71696, as corrected by 71 FR
58498).
B. What action is EPA taking on these plans?
We are proposing approval of the RFP plans submitted by
Connecticut, Massachusetts, and Rhode Island for the moderate
nonattainment areas shown in Table 1 above, as revisions to these
states' implementation plans. Note that regarding the NY-NJ-CT moderate
area, we are proposing action today only on the Connecticut portion of
the RFP plan.
C. What emission levels must Connecticut, Massachusetts, and Rhode
Island achieve by 2008?
Tables 3a-3e below contain a summary of the RFP calculations as
performed by Connecticut, Massachusetts, and Rhode Island for their
moderate ozone nonattainment areas. Some of the 2002 base year
inventory values shown in Step 1 of Tables 3a-3e are slightly higher
than those shown in Tables 2a-2e due to adjustments each state made to
their RFP SIPs to account for emissions banking and trading programs.
These adjustments are described elsewhere in this proposal. The
emission target levels are shown in step 6 of Tables 3a-3e. The
emission targets represent the maximum amount of emissions that can
occur in 2008 given the state's selected mix of VOC and NOX
percent reductions as noted in step 4 of the calculations. The RFP
plans submitted by Connecticut, Massachusetts, and Rhode Island
indicate that the projected, controlled emissions for 2008 shown in
Step 7 of Tables 3a-3e are below the 2008 emission target levels shown
in step 6, with the exception of Rhode Island's VOC emissions. To
remedy this small shortfall, Rhode Island allocated surplus
NOX emissions reductions that were available as shown in
Table 3e.

to cover VOC shortfall).
Step 7: Projected, controlled 2008 115.4.............................. 55.3.
emissions.
----------------------------------------------------------------------------------------------------------------
Note that in Tables 3a-3e above, all of the projected, controlled
2008 emission levels shown in step 7 are lower than the corresponding
2008 emission target levels shown in step 6, with the exception of the
Providence area's VOC emissions which are 1.5% higher than the 2008 VOC
target. In light of this, Rhode Island allocated an additional 1.5%
NOX reduction (which translates to 1.1 tons) to cover this
shortfall. Thus, Rhode Island has set its 2008 NOX target to
57.8 tons/day rather than 58.9 tons/day. In essence, Rhode Island has
selected a 16.6% reduction in NOX emissions and a 1.5%
increase in VOC emissions, resulting in a combined reduction of 15.1%.
EPA's guidance to states on the development of RFP plans does not
directly address the situation found in Rhode Island's RFP plan, where
surplus reductions for one ozone precursor were used to cover an
increase in emissions for the other precursor. For example, EPA's Phase
2 implementation rule provides that moderate areas such as Rhode Island
with attainment dates more than 5 years from the date of designation,
``(A) Shall provide for a 15 percent emission reduction from the
baseline year within 6 years after the baseline year. (B) May use
either NOX or VOC emissions reductions (or both) to achieve
the 15 percent emission reduction requirement. Use of NOX
emissions reductions must meet the criteria in section 182(c)(2)(C) of
the Act.'' 40 CFR 51.910(b)(2)(ii). EPA's NOX Substitution
Guidance, which EPA issued pursuant to section 182(c)(2)(C), does not
specifically address offsetting an increase in one precursor with
surplus reductions from another precursor. Thus, we reviewed the facts
of this specific case and, as explained below, have determined that the
submitted plan is consistent with the CAA requirements.
First, EPA's December 1993 NOX substitution guidance
provides the criteria that must be met in order for NOX
emission reductions to be used in RFP plans as provided by section
[[Page 57227]]
182(c)(2)(C) of the Act. The guidance directs states to ensure that
such substitution is done only to the extent that the modeled
attainment demonstration for the area indicates that this substitution
is appropriate. For example, section 2 of the guidance provides that,
``This linkage provides assurance that the RFP reductions are
consistent with the SIP attainment demonstration. States are required
to justify substitution by illustrating ``consistency'' between the
cumulative emission changes emerging from the RFP/substitution proposal
and the emission reductions in the modeled attainment demonstration.''
Rhode Island worked in conjunction with the other states within the
ozone transport region (OTR) to perform the urban airshed modeling that
the state included within its attainment demonstration, and on
development of recommended control strategies to reduce VOC and
NOX emissions in the Northeast such that the ozone NAAQS
would be met by 2009. This modeling exercise showed that both VOC and
NOX emission reductions would be needed to reach the area's
attainment goals. The resulting suite of federal and state control
measures indicate that NOX emission reductions figured
prominently in the area's attainment strategy. This is most clearly
seen by the fact that NOX emissions were projected to
decline by a greater extent than VOC emissions between the base year
and attainment year across the OTR. This illustrates that Rhode
Island's use of NOX emission reductions within its RFP plan
is appropriate.
Second, the increase in VOC emissions between 2002 and 2008 is an
artifact of EPA's RFP calculation procedure; the state's actual VOC
emissions in 2008 were predicted to be lower than they were in 2002. In
explanation, as shown in step 2 of Table 3e above, Rhode Island's 2002
anthropogenic VOC emissions were 119.2 tons per summer day (tpsd).
However, EPA's RFP calculation procedure requires that emission
reductions from the pre-1990 federal motor vehicle control program
(FMVCP) that will accrue between 2002 and 2008 be subtracted from the
2002 anthropogenic baseline because the Act, at section
182(b)(1)(D)(i), provides such reductions are not creditable for
purposes of meeting RFP requirements. This subtraction is shown in step
3 of Table 3e above, and resulted in the 2002 baseline being lowered by
5.5 tpsd to 113.7 tpsd. Since no VOC reductions were planned for in the
RFP plan, 113.7 tpsd is also the state's target level of emissions for
VOCs. As shown in step 7 of Table 3e, Rhode Island's 2008 VOC emissions
were estimated to be 115.4 tpsd. This is higher than the VOC target
emission level of 113.7 tpsd by 1.7 tpsd, but is lower than the state's
actual 2002 anthropogenic baseline emissions of 119.2 tpsd by 3.8 tpsd.
The preceding comparison is not intended to diminish the significance
of the Act's prohibition against crediting reductions due to the pre-
1990 FMVCP towards RFP. Rather, this analysis simply clarifies that
this is not a situation where a state proposes to rely on a larger-
than-15% decrease in NOX emissions to offset an actual
increase in VOC emissions; rather, here Rhode Island has in fact
reduced its VOC emissions from the baseline.
Third, in 2009, Rhode Island adopted and implemented VOC control
measures on consumer and commercial products and architectural and
industrial maintenance coatings. The effective date for these two rules
was June 4, 2009, and since the RFP plan covers the time period between
2003 to 2008 Rhode Island did not factor reductions from these rules
into their RFP analysis. However, these rules are now in effect and are
currently acting to lower VOC emissions beyond that shown in the RFP
analysis. Thus, while Rhode Island could not take credit for these
emission reductions as part of the RFP plan for 2003 to 2008,
additional reductions in VOC emissions have occurred in the state since
then.
Last, but by no means of least importance, Rhode Island is
currently in attainment of the 1997 8-hour ozone standard, and EPA
published a clean data determination for the area on June 3, 2010 (75
FR 31288). In addition, on July 28, 2010 (75 FR 44179), EPA published a
notice of proposed rulemaking indicating that this area attained the
1997 8-hour ozone standard by its attainment date of June 15, 2010.
Thus, our primary basis for approving the RFP plan is to approve the
2008 motor vehicle emission budgets contained within the plan as the
plan is not necessary to ensure that the state makes reasonable further
progress towards the 1997 standard it has already attained.
In light of these circumstances, EPA has determined that it is
appropriate to propose approval of Rhode Island's RFP plan.
D. To what extent do the RFP plans reduce ozone precursor emissions?
The Connecticut, Massachusetts, and Rhode Island RFP plans indicate
that ozone precursor emissions will be substantially reduced between
2002 and 2008, allowing each state to exceed the 15% ozone precursor
emission reduction obligation over this time frame. Compared to 2002
emission levels, the RFP plans and associated modeling showed that VOC
emissions were expected to decline by 19% in Connecticut, 16% in
Massachusetts, and 3% in Rhode Island by 2008. Additionally,
NOX emissions were expected to decline by 25% in
Connecticut, 37% in Massachusetts, and 24% in Rhode Island over this
timeframe. These percent reductions include reductions from the pre-
1990 FMVCP program shown in step 3 of Tables 3a-3e.
E. Are banked emissions properly accounted for within these RFP plans?
Although the initial RFP plan submittals made by Connecticut,
Massachusetts, and Rhode Island did not account for banked emissions,
each state made subsequent amendments to their plans that incorporated
banked emissions into the RFP analysis.
Many states operate emissions banking and trading programs. These
programs allow facilities that agree to permanently cease, or
alternatively agree to permanently reduce their emissions to levels
below allowable levels, to generate emission reduction credits (ERCs)
that can be sold or traded to other facilities. ERCs are often
purchased by facilities seeking emission offsets to meet the
requirements of the new source review (NSR) program. State air agencies
facilitate and monitor these transactions by creating and maintaining
an emissions bank where ERCs are stored until they are purchased. Since
ERCs represent emissions that may occur at some point in the future,
and RFP plans contain both base year and future year emission estimates
as well as maximum allowable (target level) emissions for the
nonattainment area as a whole, banked emissions need to be accounted
for in a state's RFP analysis.
On October 14, 2009, Connecticut submitted a revision to the RFP
plan which it had originally submitted to EPA on February 1, 2008. The
revision consisted of the incorporation of a small number of banked
NOX ERCs into the state's RFP analysis. The inclusion of the
banked ERCs into the RFP analysis did not alter the state's conclusion
that it easily meets RFP requirements. The emission estimates within
Tables 3a and 3b above reflect the revised calculations contained
within Connecticut's October 14, 2009 submittal to EPA.
On October 23, 2009, Massachusetts submitted a revision to the RFP
plan which it had originally submitted to EPA on January 31, 2008. The
revision consisted of the incorporation of a small
[[Page 57228]]
amount of banked VOC, and a larger amount of banked NOX ERCs
into the state's RFP analysis. As with Connecticut, the inclusion of
Massachusetts' banked ERCs into the RFP analysis did not change the
state's conclusion that it readily meets RFP. Tables 3c and 3d above
contains the revised RFP calculations contained within Massachusetts'
October 23, 2009 submittal.
On October 19, 2009, Rhode Island submitted a revision to the RFP
plan which it had submitted to EPA on April 30, 2008. The revision
consisted of the incorporation of banked VOC ERCs into the state's RFP
analysis. As with the above mentioned submittals from Connecticut and
Massachusetts, Rhode Island's revised plan continues to show that the
state meets its RFP emission reduction obligations, and these revised
estimates are reflected in Table 3e above.
F. What are the pollution control programs that accomplish this change
in emissions?
Many post-1990 Federal mobile source control programs which are
creditable towards meeting RFP took effect between 2002 and 2008, and
they are responsible for the bulk of the VOC and NOX
emission reductions that occurred over this time frame in Connecticut,
Massachusetts, and Rhode Island. For example, within the on-road mobile
sector the Federal Tier 2 motor vehicle control program and controls
for heavy duty diesel vehicles and fuels were significant programs that
helped to reduce emissions during this period of time. Within the non-
road sector, Federal controls on diesel engines and the Phase 2
standards for gasoline powered handheld and non-handheld equipment
began, which helped reduce emissions from that sector.
In addition to Federal measures for mobile source emissions, state-
adopted control measures also acted to reduce VOC and NOX
emissions between 2002 and 2008. In Connecticut, state-adopted rules
limiting emissions from portable fuel containers, architectural and
industrial maintenance (AIM) coatings, pressure-vacuum (PV) valves at
gasoline service stations, and requirements for solvent cleaning fluids
were adopted between 2002 and 2008, and will help to reduce VOC
emissions in the state. The portable fuel container and PV valves at
gasoline station rules have been approved by EPA into the state's SIP.
(See 71 FR 51761). The AIM and solvent cleaning rules have not yet been
approved by EPA into the State's SIP, but we are proposing approval of
them in other parts of this document and intend to approve them prior
to, or in conjunction with, our final rulemaking action on
Connecticut's RFP plan. Additionally, in May of 2003, Phase 2 of the
state's limits for emissions from municipal waste combustors began, and
this program will reduce NOX emissions from that sector.
This program has also been approved into the state's SIP. (See 66 FR
63311).
Connecticut's NOX budget program began in 2002 and so
emission reductions from the program are reflected in the state's 2002
base year inventory. Connecticut's Clean Air Interstate Rule (CAIR)
rule has taken the place of its NOX budget program beginning
in 2009. On July 11, 2008, the United States Court of Appeals for the
District of Columbia issued an opinion vacating and remanding EPA's
CAIR rule. See North Carolina v EPA, 531 F.3d 896 (DC Cir. 2008).
However, on December 23, 2008, the court granted rehearing in part and
remanded the rule back to EPA for revision without vacatur. 550 F.3d
1176 (DC Cir. 2008). Accordingly, CAIR is to be implemented as it was
originally intended until EPA revises the rule to address the court's
remand.\6\ Therefore, the NOX reductions achieved by
Connecticut's NOX budget program continue as the state has
transitioned to its CAIR program. Connecticut's CAIR program was
approved by EPA on January 24, 2008 (73 FR 4105).
---------------------------------------------------------------------------
\6\ On August 2, 2010 (75 FR 45210), EPA proposed the Transport
Rule to address the flaws in CAIR noted by the Court.
---------------------------------------------------------------------------
For the on-road mobile sector, in 2004, Connecticut adopted an
enhanced motor vehicle inspection and maintenance (I&M) program
including on-board diagnostics (OBD-2) requirements. EPA approved
Connecticut's I&M program with OBD-2 requirements into the state's SIP
on December 5, 2008 (73 FR 74019).
Massachusetts claimed emission reduction credit within its RFP plan
for the NOX emission reductions achieved by the state's
NOX SIP Call Trading program, as that program's
implementation date was in 2003. Massachusetts submitted its
``NOX Allowance Trading Program'' (also referred to as the
NOX Budget or the NOX SIP Call trading program)
to EPA as a SIP revision request, and EPA approved the rule into the
Commonwealth's SIP. Amendments to the rule were incorporated into the
state's SIP on December 3, 2007. (72 FR 67854). EPA's December 3, 2007
action also approved the Commonwealth's CAIR, which replaced the
state's NOX Budget program beginning in 2009. Therefore,
NOX emissions from sources covered by the Commonwealth's
NOX Allowance trading program will remain constrained after
2008 as the state implements its CAIR control program.
Massachusetts expects to reduce on-road mobile source emissions by
its state-run Low Emissions Vehicle (LEV) program. Massachusetts
submitted the adopted LEV program to EPA, and EPA approved it into the
state's SIP on December 23, 2002 (67 FR 78179).
At the time Rhode Island developed its RFP SIP, it was in the
process of adopting a number of control measures for stationary sources
of VOC emissions that were set to take effect in 2009, and so emission
reductions from these measures were not incorporated into the state's
RFP plan because measures in such plans need to have an impact by 2008.
Rhode Island was not required to participate in EPA's CAIR program.
Accordingly, Rhode Island's RFP plan shows that it meets the 15%
emission reduction obligation by relying exclusively on emission
reductions between 2002 and 2008 in the mobile source sector.
Additionally, the state shows that it can meet its obligation by
relying only upon NOX emission reductions. These emission
reductions occur as a result of the post-1990 Federal mobile source
control measures, as mentioned above, the state's adoption of a motor
vehicle I&M Program, and the state-adopted Low Emissions Vehicle
program. EPA has approved both of these programs into the Rhode Island
SIP. (See 66 FR 9661, and 65 FR 12476, respectively.)
G. Is EPA proposing approval of any state control measures in this
action?
We are proposing to approve three VOC control measures from
Connecticut, two of which were included in the state's February 1, 2008
SIP submittal to EPA. These rules consist of a solvent metal cleaning
rule, an architectural and industrial maintenance (AIM) coatings rule,
and an asphalt paving rule submitted on January 8, 2009. The solvent
metal cleaning and AIM coatings rules have compliance dates in May of
2008, and so achieve emission reductions that help Connecticut
demonstrate compliance with its RFP obligation. The asphalt paving rule
has a May 1, 2009 compliance date and was submitted to help the state
demonstrate that it meets the Clean Air Act section 182(b)(2)
requirement that sources in the state use reasonably available control
technology (RACT) to control air pollution. We are not proposing action
on Connecticut's overall RACM or RACT submittals at
[[Page 57229]]
this time. Additional information about each of these rules is provided
below.
Metal cleaning rule. Connecticut's February 1, 2008 SIP submittal
to EPA included an amendment to its existing SIP approved metal
cleaning rule, located at section 22a-174-20 of the Regulations of
Connecticut State Agencies (``Control of organic compound emissions,
loading of gasoline and other volatile organic compounds''), paragraph
(l) (``Metal cleaning''). The amended rule adds a limit on the vapor
pressure of solvents used in cold cleaning and other requirements to
further limit emissions of VOCs from metal cleaning operations. These
requirements are consistent with the Ozone Transport Commission's
(OTC's) 2001 model rule for solvent cleaning. The compliance date for
the rule was May 1, 2008.
AIM coatings rule. Connecticut's February 1, 2008 SIP submittal
included a new rule, section 22a-174-41 (``Architectural and industrial
maintenance coatings''), that limits VOC emissions from AIM coatings.
The state's rule establishes VOC content limits consistent with those
developed in 2001 within a model rule created by the OTC. The limits in
the state's rule are as stringent as, or more stringent than, those
contained in the Federal AIM rule adopted by EPA in December 1998 (40
CFR part 59, subpart D). The compliance date for most of the regulated
product categories was May 1, 2008. EPA notes that we are relying on
the federal enforceability of section (g)(3)(A)(iii) referenced in that
section of the rule.
Asphalt paving rule. On January 8, 2009, Connecticut submitted an
amendment to its existing SIP-approved section 22a-174-20 (``Control of
organic compound emissions, loading of gasoline and other volatile
organic compounds''), paragraph (k) (``Restrictions on VOC emissions
from cutback and emulsified asphalt''). The amended regulation includes
a seasonal ban on the use of cutback asphalt and a reduction in the
acceptable VOC content of emulsified asphalt. The compliance date for
the rule was May 1, 2009.
Connecticut held a public hearing on the first two rules mentioned
above on June 27, 2006, and held a hearing on the asphalt paving rule
on May 1, 2007. EPA reviewed draft versions of these rules and provided
comments to Connecticut during the public hearing process, and
Connecticut responded adequately to our comments. We are proposing
approval of Connecticut's revised solvent metal cleaning and asphalt
paving rules, and its new AIM coatings rule, so that they may become
part of the state's federally enforceable SIP.
H. Have these states met their contingency measure obligation?
Section 172(c)(9) of the CAA requires, in part, that nonattainment
areas provide for contingency measures ``to be undertaken if the area
fails to make reasonable further progress, or to attain the national
primary ambient air quality standard by the attainment date applicable
under this part.'' EPA has long interpreted the Act to require that
contingency measures must provide reductions of 3 percent of the
emissions from the adjusted base year inventory (57 FR 13498, 13510-
13511). States may choose to meet this requirement by consuming surplus
emission reductions shown in their RFP target level calculations, if a
surplus exists. However, pursuant to a guidance memorandum issued by
EPA on November 8, 1993,\7\ any measures that are already required are
not creditable as contingency measures. Connecticut, Massachusetts, and
Rhode Island each chose to meet the contingency obligation using
surplus emission reductions as noted in the target level calculations.
---------------------------------------------------------------------------
\7\ ``Clarification of Issues Regarding the Contingency Measures
that are due November 15, 1993 for Moderate and Above Ozone
Nonattainment Areas.''
---------------------------------------------------------------------------
Connecticut and Massachusetts can both readily show that ample
surplus emission reductions exist, and that they have implemented
controls not otherwise required. In Connecticut's case, 2008 VOC
emissions are projected to be 5.7% lower than the target, and
NOX emissions 16.5% lower than the target in the Greater
Connecticut area. For the Connecticut portion of the NY-NJ-CT area,
these surpluses are 8.3% for VOC, and 14.5% for NOX.
Connecticut has adopted a number of rules that are not otherwise
required by the CAA that it could count towards its contingency
obligation, such as its AIM coatings, automobile refinishing, and
solvent cleaning rules. For Massachusetts, 2008 VOC emissions are
projected to be 10.6% lower than the target, and NOX
emissions 22.6% lower in the Eastern Massachusetts area. For the
Western Massachusetts area, these surpluses are 10.8% for VOC, and
27.6% for NOX. The state's low emission vehicle program,
which achieves both VOC and NOX emission reductions, is an
example of a rule the state adopted that was not otherwise required by
the CAA.
Rhode Island projects that it will have a 3.6% NOX
surplus that it claims can be devoted towards meeting the RFP
contingency requirement. Given the state's reliance on Federal measures
to reduce emissions between 2002 and 2008, the state has not
demonstrated that it can meet the contingency requirement via
reductions from already-adopted NOX rules not otherwise
required by the CAA. However, Rhode Island could remedy this by relying
on the additional VOC control programs for stationary sources that it
adopted in 2009, which included rules establishing emission limits for
consumer and commercial products, and on architectural and industrial
maintenance coatings. A public hearing on these proposed rules was held
on February 20, 2009, and they were promulgated as final state
regulations May 15, 2009, with an effective date of June 4, 2009. Rhode
Island submitted these regulations to EPA as SIP revisions, but EPA has
not yet approved into the Rhode Island SIP. Section 8.3 of Rhode
Island's attainment demonstration submittal alludes to the possibility
of using reductions from these measures as an alternative means of
meeting the RFP contingency obligation. We are therefore proposing to
approve use of emission reductions from these stationary source
measures (which, as noted above, have taken effect under state law but
have not yet been approved into Rhode Island's SIP) as meeting the
state's contingency plan requirement. Section 8.3 of Rhode Island's
attainment demonstration submittal stated that reductions from these
regulations were expected to reduce VOC emissions by 2009 by 5.0 tons/
day. This would cover the 3% contingency obligation, as 3% of the
state's 2002 RFP inventory for VOCs, which is 119.2 tons/day, equals
3.6 tons/day. EPA would need to approve these two rules into Rhode
Island's SIP prior to, or in conjunction with, our taking final action
on the state's RFP plan.
I. Are transportation conformity budgets contained in these plans?
Section 176(c) of the CAA, and EPA's transportation conformity rule
at 40 CFR part 93 subpart A, require that transportation plans,
programs, and projects conform to state air quality implementation
plans. Conformity to a SIP means that transportation activities will
not cause or contribute to new air quality violations, worsen existing
violations, or delay timely attainment of the NAAQS. States are
required to establish motor vehicle emission budgets in any control
strategy SIP that is submitted for attainment and maintenance of the
NAAQS. The RFP plans submitted by Connecticut,
[[Page 57230]]
Massachusetts, and Rhode Island are control strategy SIPs, and they
contain 2008 motor vehicle budgets for VOCs and NOX by
nonattainment area. Table 4 contains these VOC and NOX
transportation conformity budgets in units of tons per summer day:
Table 4.--Conformity Budgets in the Connecticut, Massachusetts, and
Rhode Island RFP Plans

------------------------------------------------------------------------
EPA issued letters on June 2, 2008 to Connecticut, March 7, 2008 to
Massachusetts, and June 16, 2008 to Rhode Island in which we stated
these budgets were adequate for use in transportation conformity
determinations. Additionally, EPA published announcements of these
adequacy findings in the Federal Register on June 12, 2008 for
Connecticut (73 FR 33428), March 18, 2008 for Massachusetts (73 FR
14466), and June 30, 2008 for Rhode Island (36862). In today's action,
we are proposing approval of the 2008 conformity budgets for VOC and
NOX for the areas shown in Table 4 above.
Connecticut and Rhode Island increased their projected 2008 motor
vehicle emission estimates slightly to provide a buffer to their
transportation
