Regulation To Mitigate the Misfueling
of Vehicles and Engines With Gasoline
Containing Greater Than Ten Volume
Percent Ethanol and Modifications to
the Reformulated and Conventional
Gasoline Programs
Environmental Protection
Agency (EPA).
ACTION: Proposed rule.
AGENCY:
EPA is proposing a regulatory
program to help mitigate the potential
for misfueling of certain engines,
vehicles and equipment with gasoline
containing greater than 10 volume
percent (‘‘vol%’’) ethanol up to 15 vol%
ethanol (E15). This proposal is in
conjunction with the Agency’s partial
waiver, pursuant to Clean Air Act
section 211(f)(4), which allows for the
introduction into commerce of gasolineethanol blends containing up to 15
vol% ethanol for use in model year 2007
and newer on-highway light-duty motor
vehicles. The E15 waiver is limited in
scope to a portion of the light-duty fleet,
and the proposed misfueling mitigation
program will help avoid the misfueling
of all other engines, vehicles, and
equipment with unapproved fuels. This
proposed rule would require all E15
gasoline fuel dispensers to have a label
if a retail station chooses to sell E15 and
seeks comment on separate labeling
requirements for fuel blender pumps
and fuel pumps that dispense E85.
Similar to the prohibition in section
211(f)(1), the proposed rule would
prohibit the use of gasoline containing
greater than 10 vol% ethanol in vehicles
and engines not covered by the partial
waiver for E15. In addition, the
proposed rule would require product
transfer documents specifying ethanol
content and Reid Vapor Pressure (RVP)
to accompany the transfer of gasoline
blended with ethanol and a national
survey of retail stations to ensure
compliance with the these
requirements. The proposed rule would
also modify the Reformulated Gasoline
(‘‘RFG’’) program by updating the
Complex Model to allow fuel
manufacturers to certify batches of
gasoline containing up to 15 vol%
ethanol.

I. Overview
In today’s action, the U.S.
Environmental Protection Agency (EPA
or the Agency) is proposing regulations
to mitigate the potential for misfueling
of vehicles and engines with gasoline
containing up to 15 vol% ethanol
(E15).1 These regulations are being
proposed in conjunction with today’s
action by EPA granting of a partial
waiver for ethanol blends up to 15 vol%
ethanol under section 211(f)(4) of the
Clean Air Act (CAA or the Act). This
partial waiver will allow the
introduction into commerce of E15 for
use in 2007 model year (MY) and newer
light-duty motor vehicles. In partially
granting the E15 waiver, EPA imposed
a number of conditions on the refiners
and renewable fuel producers subject to
the waiver. These conditions are
designed to help ensure that E15 is
introduced into commerce for use in
MY2007 and newer light-duty motor
vehicles and flexible-fueled vehicles,
and not for use in any other vehicles or
engines. Some of the regulatory
provisions proposed today parallel
those conditions and are expected to be
a more efficient way to help ensure that
the conditions of the E15 partial waiver
decision are met and to minimize in-use
emissions increases that might result
from misfueling vehicles and engines
with E15. The proposed safeguards
would also promote the successful
introduction of E15 into commerce.
We are proposing four requirements
as part of our misfueling mitigation
regulations. The first requirement,
consistent with the partial waiver being
granted today, is a prohibition against
using E15 in MY2000 and older motor
vehicles, heavy-duty gasoline engines
and vehicles, on and off-highway
1 For purposes of this preamble, E15 refers to
gasoline-ethanol blended fuels that contain greater
than 10 vol% and no more than 15 vol% ethanol
content.

Jkt 223001
motorcycles,2 and nonroad engines,
vehicles, and equipment.3 This
prohibition is similar in nature to the
prohibition on producers of fuels and
fuel additives under section 211(f)(1);
however, the prohibition in section
211(f)(1) only applies to these upstream
parties. The prohibitions proposed
today would apply at the retail level as
well as upstream. The conditions on the
partial waiver and the regulations
proposed today are similar in nature
and have a common goal—ensuring that
E15 is used in appropriate motor
vehicles covered by the partial waiver,
and is not used in other motor vehicles
and engines. Since the Agency is
deferring a decision for MY2001–2006
light-duty motor vehicles, we are not
proposing a prohibition with respect to
the fuel used in these motor vehicles at
this time. DOE testing of MY2001–2006
light-duty motor vehicles is ongoing and
EPA expects to make a waiver
determination for these vehicles shortly
after the results of the DOE testing are
available. If EPA does not grant an E15
waiver for MY2001–2006 light-duty
motor vehicles, then we would expect to
include the same prohibitions for these
MY motor vehicles in the final
rulemaking.
Second, we are proposing labeling
requirements for fuel pumps that
dispense E15 to effectively inform
consumers regarding the appropriate
fuel to be used in vehicles and engines.
Third, EPA proposes that product
transfer documents (PTDs) from
refiners, gasoline terminals, and
oxygenate blenders specify the ethanol
content or approved level of ethanol
addition, of the fuel being sold to retail
stations or wholesale purchaserconsumer to ensure that retail stations
and wholesale purchaser-consumers
know the level of ethanol content they
are buying so that, in turn, the retail
pumps can be properly labeled. Fourth,
EPA proposes a national survey
requirement on ethanol producers and
the blenders of E15 (e.g., refiners,
gasoline terminals, oxygenate blenders)
to ensure that retail station pumps are
in fact being labeled properly. EPA is
seeking comment on including an RVP
component to this national E15 labeling
survey to help ensure that summertime
RVP requirements are being met
throughout the gasoline distribution
chain. To avoid confusion for
consumers when pumps are not labeled,
the Agency is also seeking comment on

‘‘motorcycles.’’

vehicles, and equipment are referred to as ‘‘nonroad
products.’’

requiring the labeling of non-E15
pumps. The Agency has used such
misfueling mitigation strategies to
implement several fuel programs over
the past thirty years, including the
unleaded gasoline program, the RFG
program, and the diesel sulfur program.
The Agency believes that the misfueling
mitigation measures proposed in this
rulemaking, coupled with the E15
waiver and a substantial consumer
education and outreach effort by
industry, can be an effective strategy to
help reduce misfueling and the
associated emissions impacts while
enabling the use of E15 in appropriate
vehicles.
The misfueling mitigation program
proposed today generally mirrors the
misfueling conditions in today’s partial
waiver decision. While the waiver
provides an opportunity for a fuel or
fuel additive manufacturer to meet the
conditions, the Agency believes that the
proposed safeguards would provide the
most practical method of addressing the
purposes and satisfying the conditions
of today’s partial waiver decision.
These misfueling mitigation
regulations are proposed under CAA
section 211(c), based on the projected
emission increases that would be
avoided by deterring the use of E15 in
older motor vehicles, heavy-duty
gasoline engines and vehicles,
motorcycles and nonroad products.
Engineering judgment supported by test
data, where available, forms the basis
for our technical review and
conclusions. Our engineering
assessment described in Section VI
identifies a number of emissions related
concerns with the long-term use of E15
in MY2000 and older light-duty motor
vehicles, heavy-duty gasoline engines
and vehicles, motorcycles, and nonroad
products. For motor vehicles these
concerns include the potential for
catalyst deterioration or catalyst failure
as well as material compatibility issues
that could lead to extremely elevated
exhaust and evaporative emissions. For
nonroad products and for motorcycles
the misfueling concerns include not
only the potential for elevated exhaust
and evaporative emissions but also the
potential for engine failure from
overheating. While it is not possible to
quantify precisely the frequency at
which motor vehicles and nonroad
products might experience these
problems with the use of E15, we
believe that emissions related problems
could potentially occur with enough
frequency that the resulting emission
benefits from avoiding misfueling
would outweigh the relatively low cost
imposed by the proposed regulations.
This would justify the proposed rule,

even if a very low percentage of vehicle
and engines experiences problems.
As described below in Section VI and
in the E15 partial waiver decision
document,4 our assessment indicates
that manufacturers have designed at
least MY2007 and newer light-duty
motor vehicles to be durable for use on
gasoline blends up to E15. This
conclusion is primarily based on the
recently completed catalyst durability
test program conducted by the
Department of Energy (DOE) wherein
they tested 19 vehicle models
representative of the Tier 2 motor
vehicle fleet out to their full useful life.
The study found that Tier 2 motor
vehicles continued to meet their
emissions standards after operating on
E15 for full useful life mileage
accumulation. Additionally, according
to our analysis of the DOE test data, for
Tier 2 motor vehicles we found no
statistically significant increases in the
emissions of regulated pollutants for
motor vehicles operating on E15, and no
apparent material compatibility issues,
when compared to vehicles that were
operated on E0.5 These results confirm
our engineering assessment that
MY2007 and newer motor vehicle’s
emissions should be less sensitive to the
increased ethanol content in E15. This
engineering assessment is based on the
advances in motor vehicle materials and
technology in response to in-use
experience with E10 and the
requirement that motor vehicles comply
with a series of important new EPA
emission requirements over the years,
e.g., enhanced evaporative emission
standards and E10 durability testing,
supplemental FTP emission standards,
CAP2000 in-use durability
requirements, and the Tier 2 motor
vehicle standards themselves.
For MY2001–2006 light-duty motor
vehicles, it is currently less clear
whether they could experience
significant emission increases when
fueled on E15 like MY2000 and older
motor vehicles, or continue to function
properly like the newer 2007 and newer
motor vehicles. On the one hand we
believe that many of the same elements
for ethanol compatibility of MY2007
and newer light-duty motor vehicles
also apply to MY2001–2006 light-duty

motor vehicles (e.g., enhanced
evaporative emission standards, SFTP,
CAP2000). On the other hand, they were
not all required to demonstrate
evaporative emission system durability
on E10 or to upgrade their catalyst and
emission control systems to the extent
needed to comply with the Tier 2
standards. Furthermore, currently
available test data on these model year
vehicles is much more limited. DOE is
in the process of developing relevant
data for these model year vehicles.
Specifically, DOE is conducting catalyst
durability testing on six motor vehicle
models certified to NLEV standards and
two motor vehicles certified to Tier 1
standards scheduled to be completed in
November, 2010. Additionally, a study
of in-use motor vehicles by Rochester
Institute of Technology on E20 6
suggests such motor vehicles may
operate acceptably on E20—and by
interpolation E15. However, the mileage
accumulation of RIT test vehicles is
limited and the study is still ongoing
until November 2010. This additional
information, as well as information
gathered through comment on this
proposal and any final decision on a
section 211(f) waiver for MY2001–2006
light-duty motor vehicles, will be
considered in the decisions made for the
final rule.
In addition to misfueling mitigation
measures, today’s action also proposes
slight modifications to the Reformulated
Gasoline and Antidumping fuels
programs to open the way for refiners
and importers to produce and certify
gasoline containing up to 15 vol%
ethanol. To measure compliance with
the RFG and anti-dumping standards,
the emissions performance of gasoline is
calculated using a model, called the
Complex Model, which predicts the
emissions of each regulated pollutant
based on the measured values of certain
gasoline properties. For gasoline to be
sold in the U.S., it must comply with
the RFG and Antidumping standards
and refiners are required to certify that
their fuel meets the standards by using
the Complex Model. Currently, the
equations in the model are limited to an
oxygen content of no more than 4.0% by
weight in gasoline, which is the
maximum possible amount of oxygen in
E10. EPA is proposing to modify the
Complex Model to allow fuel
manufacturers to certify batches of E15
fuel.
Finally, EPA proposes to require that
Reid Vapor Pressure (RVP) be identified

on PTDs from fuel refineries to
oxygenate blenders for conventional
gasoline to ensure that EPA summertime
RVP requirements are met. This is
necessary because the waiver
announced today is for blends that meet
the summertime gasoline volatility
standards for conventional gasoline.7 In
order to introduce a fuel that meets both
the Federal summertime RVP standards
and contains between 10 and 15 vol%
ethanol, fuel refiners would have to
create a fuel or blendstock that has
approximately 1.0 psi lower RVP than a
fuel or blendstock intended for E10 due
to the interaction between gasoline
volatility and ethanol when blended.
Oxygenate blenders would need to
know the RVP of a blendstock or have
the intended ethanol content of a
blendstock be specified on the PTD to
ensure that they know the correct
amount of ethanol that should be
blended into a fuel. The Agency is not
proposing to change RFG PTD
requirements found at 40 CFR 80.77
since RVP is carefully controlled
throughout the distribution chain in
order to comply with summertime RFG
VOC emissions performance standards.
II. Background
A. Statutory Authority
CAA section 211(f)(1) makes it
unlawful for any manufacturer of any
fuel or fuel additive to first introduce
into commerce, or to increase the
concentration in use of, any fuel or fuel
additive for use in motor vehicles
manufactured after model year 1974
unless it is substantially similar to any
fuel or fuel additive utilized in the
certification of any model year 1975, or
subsequent model year, vehicle or
engine under section 206 of the Act.
Section 211(f)(4) of the Act provides
that upon application by any fuel or fuel
additive manufacturer, the
Administrator may waive the
prohibition of section 211(f)(1). A
waiver may be granted if the
Administrator determines that the
applicant has established that the fuel or
fuel additive, and the emission products
of such fuel or fuel additive, will not
cause or contribute to a failure of any
emission control device or system (over

otherwise prohibited fuel or fuel
additive if the applicant can
demonstrate that the fuel or fuel
additive will not cause or contribute to
engines, vehicles or equipment failing to
meet their emissions standards over
their useful life.
EPA previously issued a
‘‘substantially similar’’ interpretive rule
for unleaded gasoline which allows
oxygen content up to 2.7% by weight for
certain ethers and alcohols.8 E10
contains approximately 3.5% oxygen by
weight, which means E10 is not
‘‘substantially similar’’ to certification
fuel under the current interpretation. As
explained at 44 FR 20777 (April 6,
1979), E10 received a waiver of the
substantially similar prohibition by
operation of law since EPA did not grant
or deny a waiver request for a fuel
containing 90% unleaded gasoline and
10% ethyl alcohol within 180 days of
receiving that request. This waiver by
operation of law was based on the then
current terms of CAA section 211(f)(4),
which has subsequently been amended.
Section 211(c)(1) of the Act allows the
Administrator, by regulation, to ‘‘control
or prohibit the manufacture,
introduction into commerce, offering for
sale, or sale of any fuel or fuel additive
for use in a motor vehicle, motor vehicle
engine, or nonroad engine or nonroad
vehicle (A) if, in the judgment of the
Administrator, any fuel or fuel additive
or any emission product of such fuel or
fuel additive causes, or contributes, to
air pollution or water pollution
(including any degradation in the
quality of groundwater) that may
reasonably be anticipated to endanger
the public health or welfare, or (B) if
emission products of such fuel or fuel
additive will impair to a significant
degree the performance of any emission
control device or system which is in
general use, or which the Administrator
finds has been developed to a point
where in a reasonable time it would be
in general use were such regulation to
be promulgated.’’ Today’s proposed
misfueling regulations are based on this
authority in section 211(c)(1), as well as
our recordkeeping and information
collection authority under sections 208
and 114.
B. E15 Waiver Request
On March 6, 2009, Growth Energy and
54 ethanol manufacturers submitted an
application to EPA for a waiver under
section 211(f)(4) of the CAA. This
application sought a waiver for ethanolgasoline blends of up to 15 vol%
8 See
56 FR 5352 (February 11, 1991).
VerDate Mar<15>2010

Jkt 223001
ethanol.9 On April 21, 2009, EPA
published notice of the receipt of the
application, and, as required by CAA
section 211(f)(4) of the Act, EPA
requested public comment on all
aspects of the waiver application, to
assist the Administrator in determining
whether the statutory basis for granting
the waiver request for ethanol-gasoline
blends containing up to 15 vol%
ethanol had been met. (See 74 FR
18228).
In a separate action today, EPA
waived the prohibition in CAA section
211(f)(1) to allow introduction into
commerce of E15 for use in MY2007 and
newer light-duty motor vehicles,
including passenger cars, light-duty
trucks and medium duty passenger
vehicles (hereafter light-duty motor
vehicles). EPA is deferring a decision
concerning MY2001–2006 light-duty
motor vehicles, and has denied the
waiver for all other motor vehicles.10
EPA’s partial waiver decision is based
on a determination that E15 will not
cause or contribute to a failure of
MY2007 and newer light-duty motor
vehicles to achieve compliance with the
emissions standards to which they were
certified under section 206 of the CAA
over their useful lives. EPA is still
evaluating the effect of E15 on MY2001–
2006 light-duty motor vehicles to
determine whether a waiver of CAA
section 211(f)(1) is appropriate for use of
E15 in those motor vehicles. EPA also
decided that it could not make such a
determination and therefore was
denying the waiver for all other motor
vehicles, including MY2000 and older
light-duty motor vehicles. EPA requests
comment and additional information
regarding the use of E15 in MY 2000
and older motor vehicles.
EPA issued the partial waiver with
several conditions, some of which
would be fulfilled by the safeguards
being proposed today. The conditions
apply to the upstream parties subject to
the waiver (refiners, producers of
ethanol and oxygenate blenders that
introduce E15 into commerce), and are
designed to ensure that when E15 is
introduced into commerce, it will only
be used in the appropriate light-duty
motor vehicles. Some of the conditions
call for the ethanol blenders, fuel
manufacturers, and fuel additive
manufacturers (ethanol producers) to

content, E15 needs a waiver under CAA section
211(f)(4).

take various actions to control the
distribution and use of their product so
that E15 is only used in approved motor
vehicles. The partial waiver imposes
different conditions on the different
parties. Ethanol blenders, fuel
manufacturers, and ethanol producers
that introduce E15 into commerce are
all responsible for making sure that
appropriate labeling occurs on fuel
pumps to mitigate potential misfueling.
However, this condition, in particular,
may be difficult for these parties to
satisfy given their limited control over
actions taken at retail, which, as
discussed below, prompted today’s
proposal for fuel pump labels. All three
parties are also responsible for
conducting fuel pump labeling surveys
to ensure that pumps are properly
labeled and that the correct ethanol
blends are loaded into the appropriate
tanks at retail stations. Ethanol blenders
and fuel manufacturers must also use
PTDs to properly document information
regarding the ethanol blends to help
ensure proper blending and
distribution.
In June 2010 EPA received a request
from ADM to consider, within the
context of the E15 waiver application, a
waiver for E12 for all motor vehicles.11
As discussed in the E15 waiver decision
document, EPA concluded that there
was insufficient basis to support such a
waiver for motor vehicles or nonroad
products beyond the MY2007 and
newer model year light-duty motor
vehicles for which the E15 waiver was
being granted.
C. Reasons for the Proposed Actions in
This Rulemaking
The proposed rules would directly
prohibit or control the distribution and
use of E15. The rules would apply to
parties such as retail stations that are
not directly subject to the conditions on
the waiver. Collectively, these
provisions would mitigate misfueling
and maximize the likelihood that E15 is
only used in approved motor vehicles.
This would also promote the successful
introduction of E15 into commerce. The
specific provisions are discussed in
detail in Sections III–V.
In this action, the Agency is
proposing to use its authority to help
minimize the potential for emissions
increases associated with misfueling
with E15. Importantly, the proposed
safeguards would also assist the ethanol
producers and blenders in carrying out
the conditions of the waiver. EPA
realizes that ethanol blenders, fuel
manufacturers, and ethanol producers

Federal Register / Vol. 75, No. 213 / Thursday, November 4, 2010 / Proposed Rules
srobinson on DSKHWCL6B1PROD with PROPOSALS2
may have difficulty satisfying the
conditions outlined in the E15 partial
waiver decision, particularly the fuel
pump labeling requirements. Most retail
stations are independently owned and
operated, which may make it difficult
for the ethanol blenders, fuel
manufacturers, and ethanol producers to
ensure that labels are properly placed
on fuel pumps dispensing E15. Under
CAA section 211(f)(4), EPA is limited in
what kind of conditions it can place on
a waiver decision and on whom those
conditions may be placed. For example,
EPA placed the partial waiver
conditions on the ethanol blenders, fuel
manufacturers, and ethanol producers,
the parties subject to the prohibition in
section 211(f)(1), and not on the retail
stations. This makes it difficult to
ensure effective or complete pump
labeling and misfueling mitigation.
Without Agency action that requires the
provisions proposed in today’s
rulemaking (i.e. fuel pump labeling,
PTDs, and a national survey), the
conditions contained in the E15 partial
waiver decision would likely make the
distribution of E15 impracticable.
However, under CAA section 211(c),
EPA has the authority to adopt
appropriate controls or prohibitions on
the distribution and sale of fuels and
fuel additives to avoid emissions
increases. EPA’s proposed use of this
authority would also assist the ethanol
blenders, fuel manufacturers, and
ethanol producers in carrying out the
conditions of the partial waiver so the
conditions on the E15 partial waiver are
properly implemented. Today’s
rulemaking also provides EPA with
additional tools for regulatory oversight
of the ethanol blenders, fuel
manufacturers, and ethanol producers
introducing E15 into commerce.
D. Federalism Implications
As mentioned in Section II.A, the
proposed prohibition regarding use of
E15 in MY2000 and older vehicles,
heavy-duty gasoline engines and
vehicles, motorcycles, and nonroad
engines, vehicles, and equipment is
based on the authority in section
211(c)(1) of the Act, as well as our
recordkeeping and information
collection authority under sections 208
and 114. Section 211(c)(4)(A) of the
CAA provides that no State or political
subdivision thereof may prescribe or
attempt to enforce ‘‘for purposes of
motor vehicle emission control’’ any
control or prohibition ‘‘respecting any
characteristic or component of a fuel or
fuel additive’’ in a motor vehicle or
motor vehicle engine if EPA has
prescribed a control or prohibition
applicable to such characteristic or
VerDate Mar<15>2010
18:04 Nov 03, 2010
Jkt 223001
component of the fuel or fuel additive
under section 211(c)(1). This
prohibition applies to all States except
California, as provided in section
211(c)(4)(B). Also, section 211(c)(4)(A)
applies only to controls or prohibitions
respecting any characteristics or
components of fuels or fuel additives for
motor vehicles or motor vehicle engines,
that is, highway vehicles. Therefore, a
State control or prohibition would be
preempted under section 211(c)(4)(A),
only if it is ‘‘for the purposes of motor
vehicle emission control.’’ Further, even
if a State rule is established for purposes
of motor vehicle emission control, it
will not be preempted under section
211(c)(4)(A) unless it is for the same
‘‘characteristic or component of a fuel or
fuel additive in a motor vehicle or motor
vehicle engine’’ for which EPA has
prescribed a control or prohibition
under section 211(c)(1)(A). Today’s
action proposes a rule that would limit
the ethanol content in fuel used in
certain vehicles and engines as well as
proposes misfueling mitigation
measures to effectuate that limitation.
The Agency is not aware of any State
rules or laws that would be preempted
by today’s proposed rule if adopted.
States have not controlled ethanol
volumes in gasoline for purposes of
motor vehicle emission control. Also,
our rule would not require States to
change their existing labels. The rule as
proposed would impose no substantial
direct costs, nor would it have any
substantial direct effects on State or
local governments. EPA requests
comments on the issue of preemption of
State fuel programs.
Further, EPA consulted with State
and local officials early in the process
of developing the proposed action to
permit them to have meaningful and
timely input into its development. EPA
met with members of the National
Association of Clean Air Agencies
(NACAA) to discuss the nature of
today’s proposed rule. Additionally, we
provided State and local governments
an opportunity to provide comment on
the implementation of misfueling
mitigation measures for a partial E15
waiver in both the RFS2 NPRM (see 74
FR 25016) and the E15 waiver request
notice (see 74 FR 18228). We received
comments from only one State on this
issue in the RFS2 NPRM, and it
supported efforts for properly labeling
fuel pumps containing gasoline-ethanol
blends.
III. Misfueling Mitigation Measures
As explained above, CAA section
211(c) grants the Agency authority to
control or prohibit the distribution of a
fuel or fuel additive when it will
PO 00000
Frm 00007
Fmt 4701
Sfmt 4702
68049
significantly impair emission controls or
the emission products from that fuel
will cause or contribute to air pollution
that we reasonably anticipate may
endanger public health or welfare. As
more fully discussed in Section VI, we
are proposing to prohibit use of E15 in
MY2000 and older light-duty motor
vehicles, and in all heavy-duty gasoline
engines and vehicles, motorcycles and
nonroad products based on the
projected increased emissions that
would occur from using E15 in those
motor vehicles and nonroad products.
We are also proposing to prohibit
gasoline retail stations and wholesale
purchaser-consumer facilities from
selling E15 for use in these products if
pumps at those locations are not
properly labeled. Since the Agency is
deferring a decision for MY2001–2006
light-duty motor vehicles, we are not
proposing a prohibition for fuel used in
these motor vehicles at this time. DOE
testing of MY2001–2006 light-duty
motor vehicles is ongoing and EPA
expects to make a waiver determination
for these vehicles shortly after the
results of the DOE testing are available.
If EPA does not grant an E15 waiver for
MY2001–2006 light-duty motor
vehicles, then we would expect to
include the same prohibitions for these
MY motor vehicles in the final
rulemaking .12
EPA is proposing a misfueling
mitigation strategy to effectuate those
proposed prohibitions and to more
generally limit the use of E15 to
MY2007 and newer light-duty motor
vehicles as approved today in the E15
partial waiver decision. We believe that
there are four important components to
an effective misfueling mitigation
strategy for reducing the potential for
misfueling with E15. First, effective
labeling is a key factor. Labeling is
needed to inform consumers of the
potential impacts of using E15 in
vehicles and engines not approved for
its use, to mitigate the potential for
intentional and unintentional
misfueling of these vehicles and
engines. Labeling is also done at the
point of sale where the consumer most
likely will be choosing which fuel to
use. Second, retail stations and
wholesale purchaser-consumers need
assurance regarding the ethanol content
of the fuel that they purchase so they
can direct the fuel to the appropriate
storage tank and properly label their
fuel pumps. The use of proper
12 Even though we are not proposing an actual
prohibition for motor vehicles MY2001–2006, it is
still unlawful to use E15 in these motor vehicles
until an E15 waiver is granted for these motor
vehicles.

srobinson on DSKHWCL6B1PROD with PROPOSALS2
documentation in the form of PTDs has
proven to be an effective means of both
ensuring that retail stations know what
fuel they are purchasing and as a
possible defense for retail stations in
cases of liability in the event of a
violation of EPA standards. Third,
national labeling and fuel sampling
surveys are necessary to ensure that
retail stations are complying with
labeling requirements, ethanol blenders
are not blending more than the stated
amount of ethanol on PTDs, and
assuring downstream compliance for
fuel refiners. The Agency has used this
general strategy to implement several
fuel programs over the past thirty years,
including the unleaded gasoline
program, the RFG program, and the
diesel sulfur program. EPA solicits
comments on all of these provisions as
more fully described below.
The fourth component of an effective
misfueling mitigation strategy is
effective public outreach and consumer
education. Outreach to consumers and
stakeholders is critical to mitigate
misfueling incidents that can result in
increased emissions and vehicle or
engine damage. Consumers will need to
be engaged through a variety of media
to ensure that accurate information is
conveyed to the owners and operators of
vehicles and engines.
The misfueling mitigation program
proposed today generally mirrors the
misfueling conditions in today’s partial
waiver decision. While the waiver
provides an opportunity for a fuel or
fuel additive manufacturer to meet the
conditions, the Agency believes that the
proposed the measures would provide
the most practical method of meeting
the purposes of and satisfying the
conditions of today’s partial waiver
decision.
A. Labeling Requirements
Today’s rule proposes to require that
retailers and wholesale purchaserconsumers who choose to sell or
dispense E15 must label any dispensers
of this gasoline-ethanol blend. We are
also seeking comment on requiring that
dispensers of other gasoline-ethanol
blends that contain 10 vol% ethanol or
less to be labeled at such time as a retail
station chooses to dispense E15 to help
alleviate any confusion to consumers.
Additionally, we seek comment on
requiring labels for E85 pumps and
blender pumps.
1. E15 Labels
We are proposing requirements that
gasoline pumps dispensing E15 be
labeled. The label would have to
indicate that the fuel contains up to 15
vol% ethanol—that is, the fuel is a
VerDate Mar<15>2010
18:04 Nov 03, 2010
Jkt 223001
gasoline-ethanol blend that contains
greater than 10 vol% ethanol but not
more than 15 vol% ethanol. Retailers
and wholesale purchaser-consumers
who choose to sell E15 would be
required to label pumps dispensing E15,
clearly indicating that the fuel should
not be used in MY2000 and older motor
vehicles, motorcycles, heavy-duty
gasoline engines and vehicles, or any
nonroad products. However, EPA also
proposes that the label would be
modified if the E15 waiver is extended
to earlier model year vehicles and/or
nonroad products.
Based on the Agency’s experience
with fuel pump labeling for Ultra-Low
Sulfur Diesel (ULSD) and Low Sulfur
Diesel (LSD) (see 40 CFR 80.570), there
are four important elements to an
effective label for misfueling. The
Agency proposes that the language of
the E15 label would have four
components: (1) An information
component; (2) a legal approval
component; (3) a technical warning
component; and (4) a legal warning
component. Together, these four
components highlight the critical
information necessary to inform
consumers about the impacts of using
E15.
a. Information Component
The first component informs
consumers of the maximum ethanol
content the fuel may contain. For E15,
the Agency proposes that the
information component of the label
should contain two aspects, both an
acronym for the fuel (in this case E15)
and a description of what the acronym
means (in this case informing
consumers that the fuel may consist of
a range of ethanol up to a maximum of
15 vol% ethanol by volume). We
propose that this component of the label
read:
This fuel contains 15% ethanol maximum
We propose that this label be applied to
any fuel dispenser with greater than
10% ethanol but not more than 15 vol%
ethanol. Thus, in the case of any midgrade fuel that might be blended from
E10 and E15, it would also be required
to have the E15 label.
b. Legal Approval Component
The second component of the label
language would include information
that informs consumers of what vehicles
and engines are approved to use E15,
mirroring EPA’s decisions taken in the
waiver context. Since EPA granted a
partial waiver of E15 limiting its legal
use to MY2007 and later light-duty
motor vehicles, its use is only permitted
in these motor vehicles. Based on the
PO 00000
Frm 00008
Fmt 4701
Sfmt 4702
partial waiver, the Agency proposes that
this portion of the label read as follows:
Use only in:
2007 and newer gasoline cars
2007 and newer light-duty trucks
Flex-fuel vehicles.
As discussed elsewhere in today’s
proposal, if EPA decides to include
more model years in a subsequent
waiver decision based on the findings of
the testing program, then the model year
distinction on the label would also need
to be adjusted accordingly. We
anticipate this will occur before this
rulemaking is finalized, and we will
make that adjustment in the final rule.
Therefore, the proposed language could
read as follows:
Use only in:
2001 and newer gasoline cars
2001 and newer light-duty trucks
Flex-fuel vehicles.
c. Technical Warning Component
The third component of the label
language would alert consumers that
use of E15 in other engines, vehicles,
and equipment might cause damage to
these products. Our experience with
past labeling provisions supports the
need for both the legal and technical
warning so that consumers are informed
of the reason for the prohibition. As
discussed more fully in Section VI, it
appears that use of E15 in these
particular products may not only lead to
increased emissions but also has the
potential, even if limited in nature, to
lead to damage of motor vehicle and
nonroad product components. Without
this component to the label, consumers
may more likely be tempted to
misfuel—particularly if the price in the
marketplace for E15 is lower than E10.
Therefore, EPA proposes the following
language: ‘‘This fuel might damage other
vehicles or engines.’’
d. Legal Warning Component
The fourth component of the label
would inform consumers that using E15
in a vehicle or engine not approved for
E15 use violates Federal law. This is
similar to the approach used to mitigate
the use of LSD in 2007 and newer onhighway diesel engines. Based on that
experience, EPA believes that explicitly
notifying consumers that E15 is
prohibited by Federal law for use in
MY2000 and older motor vehicles,
heavy-duty gasoline engines and
vehicles, on and off-highway
motorcycles, and all nonroad products
will result in consumers being less
likely to misfuel.
Based on the language currently used
on the LSD label (see 40 CFR 80.570),
the Agency proposes that the label read
E:\FR\FM\04NOP2.SGM
04NOP2
Federal Register / Vol. 75, No. 213 / Thursday, November 4, 2010 / Proposed Rules
68051
label. This would draw consumer
attention to the label and help mitigate
both intentional and unintentional
misfueling. Therefore, we propose to
have the word ‘‘CAUTION!’’ appear at
the top of the label before the
information component. The Agency
also considered the use of the word
‘‘ATTENTION’’ instead of ‘‘WARNING’’
or ‘‘CAUTION.’’ We specifically seek
comment on using the term
‘‘CAUTION!’’ versus ‘‘WARNING’’ or
‘‘ATTENTION’’. In addition, the Agency
is also interested in whether using
‘‘STOP’’, with or without including a
depiction of a stop sign, would be an
appropriate way to draw consumers’
attention to the label. We seek comment
on whether there are other words that
would better convey the message to
consumers.
EPA seeks comment on all aspects of
the label language. For example, we
seek comment on whether any
additional label language should be
required or whether any language
should be removed. In particular, we
seek comment on ways to portray the
information in ways that are the most
concise and meaningful to consumers.
EPA proposes that the pump labels for
E15 be required to be placed on pumps
that will dispense E15 prior to any
commercial sale of E15.
One issue that arose from the labeling
provisions of the diesel sulfur program
was that the diesel sulfur labeling
provisions were written in a way that
allowed flexibility in color and design,
causing retailers difficulty with coming
up with a suitable design that satisfied
EPA labeling requirements at the least
possible cost. To help address this issue,
stakeholders met with EPA to discuss
standardized label designs that would
both satisfy EPA diesel sulfur
requirements and make it easier for
retail stations to procure labels. Labeling
templates were designed and made
available to retail stations to use. Based
on this experience, we are proposing
more explicit specifications for the E15
label, covering not only the content, but
also the appearance of the E15 pump
label.
In today’s rulemaking, we are
proposing similar appearance and
placement requirements for the E15
labels that were required for the diesel
sulfur program labels. We propose that
the titles of the labels (e.g., E15) must be
24-point, white, bold Arial font, the
‘‘CAUTION!’’ text should also be red,
uppercase 16-point bold type, the text in
the labels which describes the ethanol
content of the fuel must be 20-point
type and that all other required language
in the labels must be 14-point black,
Arial font. We propose that the word
‘‘prohibits’’ be in 14 point, black, bold,
italic, Arial font. All text should be
centered with the arrangement and
spacing of the text consistent with the
illustration. We further propose that the
label be 3.625’’ width by 3.125’’ height
and that the background for the area
which includes ‘‘CAUTION!’’, the title
(i.e. ‘‘E15’’), and the ethanol content (i.e.,
‘‘15% Ethanol Maximum) shall be 1inch wide and neon-orange in color,
except that a rectangular white
background large enough to encompass
‘‘CAUTION!’’ shall be superimposed on
this neon-orange background. While we
believe it is important to propose these
specific label appearance requirements
to aid in consumer recognition and
avoid unnecessary burden on retailers
in developing their own designs, we
also recognize that there is a great deal
of variation in the design of fuel pumps
and dispensers throughout the nation.
Consequently, we not only seek
comment on all visual aspects of our
proposed label, but also suggest that if
changes are deemed necessary,
regulated and other interested parties
work together to provide us with a
consensus recommendation in their
comments, if possible.
In addition to content and
appearance, the placement of the label
on the pump is also of concern given the
limited space available on the fuel
pump itself. In the diesel sulfur program

e. E15 Label Proposal

EP04NO10.000
srobinson on DSKHWCL6B1PROD with PROPOSALS2
as follows: ‘‘Federal law prohibits its use
in other vehicles and engines.’’
The Agency has traditionally had
‘‘WARNING’’ language appear before the
legal warning component to better draw
consumers’ attention to the prohibition
of using a fuel in certain vehicles and
engines (e.g. LSD in 2007 and newer
highway diesel vehicles). After
consultation with stakeholders, it was
suggested that the Agency should both
change ‘‘WARNING’’ to ‘‘CAUTION!’’
and place this language at the top of the
68052
Federal Register / Vol. 75, No. 213 / Thursday, November 4, 2010 / Proposed Rules
srobinson on DSKHWCL6B1PROD with PROPOSALS2
we required that labels must be placed
on the vertical surface of each pump
housing and on each side that has gallon
and price meters and that labels be on
the upper two-thirds of the pump in a
location where they are clearly visible
(see 40 CFR 80.570(d)). We propose the
same placement requirements for the
E15 labels. However, since most States
require labels for gasoline blended with
ethanol and the Federal Trade
Commission (FTC) requires labels
specifying minimum octane levels
across grades of gasoline, the addition of
the proposed E15 label may impact
placement of other labels required by
State or Federal law. Furthermore, FTC
has proposed a mid-level ethanol
gasoline-blend label (described below)
in addition to its octane label which
may further confuse consumers and
make E15 label placement difficult. The
Agency seeks comment on the proposed
placement of the E15 label in order to
most effectively mitigate misfueling,
while at the same time avoid
interference with other labels on the
pumps.
2. Additional Fuel Pump Labeling
Requirements
In addition to the E15 label proposed
above, the Agency is seeking comment
on three additional fuel pump labels
that would provide consistent labeling
across all gasoline fuel pumps. First, the
Agency seeks comment on requiring a
label on gasoline dispensing fuel pumps
that are dispensing fuels which contain
ethanol in concentrations up to 10 vol%
(‘‘E10 label’’).13 We further seek
comment on whether E10 labels should
be required at a retail station only if and
when E15 is made available for sale at
a particular retail station. Such an E10
label would have similar appearance
and location requirements to the E15
label and the required label language
would follow a similar form to that of
the E15 label so as to standardize labels
for consumers.
The purpose of such a label would be
to enhance the effectiveness of the E15
label to protect against consumer
misfueling and the associated emissions
impacts. Without such labels,
consumers may be confused regarding
whether an unlabeled pump was
appropriate for their vehicle or engine,
undercutting the effectiveness and
confidence in the E15 label. This
approach is consistent with the labeling
requirements we used in the diesel
sulfur program where we required the
use of labels specifying which type of
diesel fuel (low-sulfur diesel, ultra-low

the fuel contains no ethanol, it could be
labeled as such.

sulfur diesel, etc.) was being dispensed
from each pump dispensing diesel fuel.
However, since increasing the number
of labels will increase the total cost to
retail stations by requiring that all
gasoline dispensing fuel pumps at a
station be labeled, we seek comment on
the appropriateness of such a
requirement. The Agency seeks
comment on the following E10 label
language:
E10
(Contains up to 10% Ethanol)
For use in all gasoline vehicles and
engines.
The Agency also seeks comment on
requiring a label on pumps distributing
E85 fuel. E85 is fuel that contains up to
85 vol% ethanol and at least 15 vol%
gasoline, used by flex fuel vehicles
(FFVs).14 As we noted in the RFS2
NPRM, fuel retailers expressed concern
that if E85 were priced low enough to
encourage FFV owners to fuel on it
more frequently, then owners of nonFFVs would also be enticed to misfuel
on it (see 74 FR 24977). This could
cause the vehicles and equipment to
operate very poorly, increasing
emissions, as well as cause potential
long-term damage and long-term
emissions increases. We believe that in
most cases fuel pump labels warning
that the use of E85 in non-flex fuel
vehicles is illegal, can damage the
vehicle, and can void vehicle
manufacturer warranties may be a
sufficient disincentive to mitigate
intentional misfueling. Non-FFVs and
nonroad products were not designed for
operation on E85 and may experience
serious emissions increases, operability,
and driveability issues, particularly
with prolonged use (e.g. accelerated
catalyst deterioration, fuel system
component failures, etc.).
Such an E85 label would have similar
appearance and location requirements
to the E15 label (discussed above) and
the required label language would
follow a similar form to that of the E15
label. The Agency seeks comment on
the following E85 label language:
E85
(Contains up to 85% Ethanol)
For use in flex-fuel vehicles only.
WARNING
Federal law prohibits use in all other
vehicles and engines.
May damage these vehicles and engines.
comment on the label language for the
E85 label.
The Agency also seeks comment on
requiring labels for so-called blender
pumps. Blender pumps allow station
owners to blend E85 and gasoline in
their storage tanks to create intermediate
gasoline-ethanol blends. This allows
either station owners or potentially FFV
drivers to choose which gasolineethanol blend they prefer, based on
operating characteristics and price.
During both the RFS2 and E15 waiver
request comment periods, the Agency
received several comments asking us to
require labeling provisions for blender
pumps to address misfueling. Similar to
E85, consumers may misfuel their nonFFVs and engines on ethanol blends
greater than 10% (greater than 15% for
2007 and newer light-duty motor
vehicles) due to possible price
differences between intermediate
ethanol blends and gasoline. Non-FFVs
and nonroad products were not
designed for operation on such high
levels of ethanol and may experience
serious emission, operability, and
driveability issues, particularly with
prolonged use (e.g. accelerated catalyst
deterioration, fuel system component
failures, etc.).
Such a blender pump label would
have similar appearance and location
requirements to the E15 label (discussed
above) and the required label language
would follow a similar form to that of
the E15 label. The Agency seeks
comment on the following two blender
pump label language options. The first
option’s language addresses a situation
where a vehicle operator can ‘‘dial’’ their
own gasoline-ethanol blend level.
E15–E85
(Contains between 15% and 85% ethanol)
For use in flex-fuel vehicles.
WARNING
Federal law prohibits use in all other
vehicles and engines.
May damage these vehicles.
The second option’s language is to
provide for a specific blend of higher
than 15 vol% ethanol content within
this range, in which case the station
owner would replace the option 1’s
language with the specific value. The
language for option 2 would be as
follows:
We request comment on whether the
proposed labeling requirements would
provide sufficient warning to consumers
not to refuel non-flex-fuel vehicles with
E85. Additionally the Agency seeks
EXX
(Contains up to XX% Ethanol)
For use in flex-fuel vehicles.

to run on gasoline or gasoline-ethanol blends up to

pump setting is expected to dispense
that is greater than 15 vol% ethanol.
The blender pump labels would not
need to specify blends containing
between 10 and 15% ethanol because
any such fuel pumps would be required
to display the E15 label. However, since
a blender pump may dispense several
intermediate ethanol blends (e.g. E20,
E30, E40, etc.), the label should specify
a range of ethanol content from E15
through E85. Therefore, under this
second option the blender pump would
have multiple labels for each of the
blends that the pump dispenses.
3. Stakeholder Labeling Suggestions
In anticipation of this proposal, EPA
met with several stakeholders to discuss
the potential label language used for the
E15 label language. To date, the Agency
has received label language suggestions
from Growth Energy.15 AllSAFE and the
American Petroleum Institute provided
EPA with their public comments to the
FTC labeling proposal.16 Copies of these
labeling recommendations may be
viewed in the docket.17 We have
considered the suggestions in these
comments for our proposal, but
nevertheless seek comment on whether
and if so how to modify our label
proposals based on these and other
suggestions.

4. FTC Labeling Proposal
On February 26, 2010, the Federal
Trade Commission (FTC) issued a
proposed rulemaking that proposes
explicit requirements for gasolineethanol blends that contain more than
10 vol% ethanol and less than 70 vol%
ethanol (‘‘Mid-Level Ethanol blends’’)
(see 75 FR 12470). Since the FTC
labeling proposal did not contemplate
the granting of a waiver for E15, it
would have to be modified to be
consistent with our recent E15 partial
waiver decision. In addition, as
discussed above, we believe it is
important that the label contain certain
components and language necessary to
both inform and warn the consumer that
are not fully captured in the FTC labels.
Therefore, EPA is working with FTC
to develop coordinated labeling
requirements and seeks comment on
how best to achieve this outcome.
Preferably, one label would be
developed that meets EPA and FTC

labeling requirements, since imposing
separate labeling requirements may
confuse consumers and would
ultimately limit the effectiveness of
labeling to mitigate misfueling.
Requiring two separate labels would
also create issues concerning the
placement of the E15 label and may
impose an unnecessary burden on retail
stations. Finally, we also believe that to
ensure the effectiveness of all gasoline
pump labels, it is important that they be
of similar type and format (i.e. those for
E10, E15, E85, and blender pumps).
5. Labeling Requirements and Liability
for Misfueling
It is important to note that compliance
with the labeling requirements specified
in this rule does not protect responsible
parties from liability for misfueling.
Today’s regulations not only impose
labeling requirements but also a
prohibition of the sale or offer for sale
of E15 for use in unapproved engines,
vehicles, and equipment (see section
III.G below). Compliance with the
labeling requirement does not ensure
that the responsible parties have not
made prohibited sales. In addition, our
regulations do not address issues of
common law or contract liability
between private parties.
B. Product Transfer Document
Requirements
Product transfer documents (PTDs)
are customarily generated and used in
the course of business and are familiar
to parties who transfer or receive
blendstocks, base gasoline for oxygenate
blending and oxygenated gasoline. In
addition, EPA has historically put in
place certain requirements for PTDs for
reformulated gasoline blends and
blendstocks to help ensure downstream
compliance with our fuel standards. The
introduction of E15 into the marketplace
results in the need for additional
information on the PTDs that
accompany the transfer of gasoline and
the base gasoline/gasoline blendstocks
used for oxygenate blending, both for
reformulated gasoline and conventional
gasoline. The type of additional
information needed is different
upstream versus downstream of the
point of ethanol addition. We believe
that the additions discussed below to
existing PTDs are necessary to minimize
misfueling, to help ensure downstream
compliance with our fuel standards, and
thereby to support the introduction of
E15.
1. PTD Requirements Downstream of the
Point of Ethanol Addition
Downstream of the point where
ethanol blending takes place,
PO 00000
Frm 00011

information on the maximum ethanol
concentration in the ethanol blend is
needed to help ensure that fuel
shipments are delivered into the
appropriate storage tanks at retail and
fleet fueling facilities.18 Information on
the maximum Reid Vapor Pressure
(RVP) of E0, E10 and E15 blends is
needed on PTDs to help ensure that the
fuel is compliant with the applicable
summertime RVP requirements. The
RVP reported on the PTD for E10 and
E15 blends could be based on the
intended RVP that the manufacturer of
the blendstock for oxygenate blending
designed for as identified on the PTD for
the blendstock.19 Therefore, RVP testing
after the addition of ethanol would not
be necessary to provide the information
on RVP that would be required on the
PTD.
We are proposing that the following
statements would be included on the
PTDs for the various fuel blends:
For E0: ‘‘E0: Contains no ethanol.
The RVP does not exceed [Fill in
appropriate value]’’
For E10: ‘‘E10: Contains between 9 and 10
volume percent ethanol
The RVP does not exceed [Fill in
appropriate value]’’
For E15: ‘‘E15: Contains up to 15 volume
percent ethanol
The RVP does not exceed [Fill in
appropriate value]’’
For EXX: ‘‘EXX—Contains up to XX%
ethanol.
‘‘EXX’’ refers to fuels blends above E15
up to and including E85 and fuel blends
below 9 volume percent ethanol. The
maximum potential ethanol content of
the fuel would be required to be
specified on the PTD in the place of
‘‘XX’’.
We request comment on whether
additional language on E10 PTDs is
needed to inform parties that a blend
containing between 9 and 10 volume
percent ethanol which benefits from the
1 psi RVP waiver may not be
commingled with an E0 or E15 blend.20
We request comment on whether any
other additional information should be
18 Currently, ethanol blending typically takes
place at the terminal. Evaluations are underway
which may facilitate the shipment of ethanolgasoline blends by pipeline to terminals. Hence,
although the proposed PTD requirements regarding
maximum ethanol content currently would
typically apply to parties downstream of the
terminal, parties upstream of the terminal may need
to include information on maximum ethanol
concentration on product PTDs in the future.
19 This is dependent on the proper amount of
ethanol being added to the blendstock, and on the
product being segregated from all products with a
different RVP.

2. PTD Requirements Up to and
Including the Point of Ethanol Addition
srobinson on DSKHWCL6B1PROD with PROPOSALS2
Upstream of the point where E10 and
E15 blends are manufactured,
information is needed on the PTDs for
base gasoline or gasoline blendstock
used for oxygenate blending (BOB) 21 to
facilitate ethanol blender compliance
with the applicable EPA summertime
RVP requirements.22 This information
would need to include the maximum
potential RVP of the BOB and the
maximum ethanol concentration that
may be added to the BOB.
To satisfy these needs, we are
proposing that PTDs for BOBs for use in
the manufacture of ethanol blends that
are subject to summertime RVP controls
include the maximum RVP of the BOB.
We are also proposing that such PTDs
in non-RFG areas indicate what ethanol
concentration is suitable to be blended
with the BOB. The RFG requirements
found at 40 CFR 80.77 already contain
requirements that PTDs indicate what
oxygenate and oxygenate amount are
suitable to be blended with the
reformulated blendstocks for oxygenate
blending (RBOBs).
We are proposing that the following
statements would be included on the
PTDs for BOBs in non-RFG areas:
advantage of the 1psi allowance for E10
in order to help prevent downstream
violations of the RVP standards: ‘‘The
use of this gasoline to manufacture a
gasoline-ethanol blend with less than 9
vol% ethanol or E15 may cause an RVP
violation.’’ We request comment on
whether any additional information
should be provided on the PTDs for
BOBs.
3. General PTD Requirements
We are proposing that on each
occasion when any person transfers
custody and/or ownership of any
gasoline or base gasoline/gasoline
blendstock used for oxygenate blending,
the transferor would be required to
provide the transferee with an
appropriate PTD identifying the
gasoline/blendstock/base gasoline and
its characteristics (as defined below), as
well as such general information as the
names and addresses of the transferor
and transferee, the volume of product
being transferred, the location of the
product on the date of transfer, and
specific information described in this
preamble. We are proposing that all
parties would be required to retain PTDs
for a period of not less than five years
and would be required to provide them
to EPA upon request. Five years is the
normal record retention requirement for

C. Retail Fuel Dispenser Label and Fuel
Ethanol Content Survey
To help mitigate the potential for
misfueling, oversight of fuel retailer
compliance with the proposed E15
labeling requirements and of the actual
ethanol content of the dispensed fuel in
comparison to the information on the
label is needed. To provide adequate
oversight, EPA conditioned the E15
partial waiver on a requirement that
ethanol blenders, ethanol producers,
ethanol importers, petroleum refiners,
and petroleum importers participate in
a survey of compliance at fuel retail
facilities.23 The E15 partial waiver
decision specified that an EPAapproved survey plan is to be in place
prior to introduction of E15 to the
marketplace and that the results of the
survey must be provided to EPA for use
in its enforcement and compliance
assurance activities.
Today’s notice contains our proposal
on requiring a survey as part of a
misfueling mitigation program. This
proposal covers how the required
survey should be formulated and
conducted. As discussed in section
III.G., we are proposing that the survey
could be used to meet the periodic
sampling and testing elements of a
regulated party’s affirmative defenses to
presumptive liability in cases where
instances of noncompliance with the
applicable maximum ethanol content
specification are discovered. Should
EPA finalize the additional labeling
requirements that we requested
comment on in section III.A.2. of this
proposal, evaluation of retailer
compliance with these labeling
requirements would also be included in
the survey. Regardless of whether we
finalize labeling provisions, testing on
the ethanol content of the fuel delivered
from all non-FFV dispensers would
need to be included in the survey to
help mitigate misfueling.
The survey requirements that we are
proposing are based on an existing

survey of compliance with the EPA
labeling requirements for retail diesel
fuel dispensers, and with the maximum
allowable sulfur content of the diesel
fuel delivered from these dispensers
under EPA’s ULSD program. EPA
recently codified the requirements for
this diesel fuel survey in a direct final
rule that became effective on July 12,
2010.24 The reformulated gasoline (RFG)
program also utilizes a compliance
survey program to ensure seasonal RFG
area requirements are met for predicted
emissions performance based on average
area fuel parameters. Based on the
ULSD and RFG programs, we are
proposing two options for obligated
parties to satisfy the survey
requirement. Survey Option 1 allows
individual obligated parties to elect to
individually survey gasoline and retail
stations anywhere their fuel might be
sold. Survey Option 2 allows obligated
parties to form a consortium that
contracts an independent survey
association to conduct a national
ethanol content and E15 labeling
survey.
For Survey Option 1, we propose that
obligated parties choosing the
individual survey option must survey
labels and ethanol content at retail
stations wherever their gasoline may be
distributed if it may be blended as E15.
Prior to conducting such a survey a
survey plan would have to be approved
by EPA. We seek comment on all
aspects related to Survey Option 1.
For Survey Option 2, we propose that
the survey would consist of a
nationwide program of sampling and
testing designed to provide oversight of
all retail stations that sell gasoline.
Details of the proposed survey
requirements are similar to those
included in the ULSD and RFG
programs. We propose that the survey
organization would be required to
submit survey plans on an annual basis
that would be applicable from January
1 through December 31. We propose
that EPA would review the first survey
plan within two months of its receipt.
We propose that the survey organization
would be required to submit subsequent
survey plans to EPA for approval by
November 1 of the year proceeding the
calendar year in which the sampling
and testing program would be
implemented. The Agency also proposes
that proof that the amount of money
necessary has been paid to the surveyor
is sent to EPA no later than December
15 of the year proceeding the calendar
year in which the sampling and testing

program would be implemented. For the
first annual survey, we propose that
proof of payment be submitted to the
Agency no later than one month before
the sampling and testing program would
be implemented. We seek comment on
the deadlines for both the survey plan
and proof of payment for the survey for
the first survey and on subsequent
surveys.
We propose that the sampling and
testing program would ensure
comprehensive geographic coverage
nationally representative of gasoline
sold at retail outlets by providing
proportionate coverage of gasoline
across three sampling strata. These three
strata generally refer to: (1) Densely
populated areas, which include
Metropolitan Statistical Areas and the
reformulated gasoline control areas; (2)
transportation corridors, which are
based on interstate highways outside the
densely populated areas;25 and (3) rural
areas, which include all areas not
included in the previous two strata.
These areas would be subdivided into
clusters, generally based on groupings of
counties. The specific criteria used for
selecting sampling areas for each survey
plan would be subject to EPA approval.
We seek comment on all aspects of the
proposed elements that a survey plan
should include.
Comment is specifically requested on
the criteria which should be used to
determine the minimum sample size for
the survey. The sampling and testing
program would need to both accurately
estimate the proportion of retail stations
that are non-compliant with E15
labeling and ethanol content
requirements and provide a credible
deterrent to deliberate or inadvertent
violations of downstream enforcement
standards. For the ULSD survey
program, we require a minimum of
5,250 samples annually. For a national
survey looking at all gasoline retail
stations, we believe the minimum
number of samples needs to be greater
because there are more than three times
the number of retail stations that sell
gasoline compared with stations that
sell diesel. We propose that the survey
take a minimum of 7,500 samples
spread across four quarterly surveys. We
also propose a sample size equation
similar to the one used to determine
sample sizes for the ULSD survey
program (see equation in the proposed
regulations at 80.1502(b)(4)(v)(A)). This
equation bases sample size on the
25 Transportation corridors would include areas
immediately adjacent to the highways themselves
and a swath within several miles on each side of
the highway. For any given survey, a certain length

appropriate as a sampling unit or cluster.

proportion of retail stations that are
non-compliant. We seek comment on
both the minimum number of samples
and the method for determining samples
sizes.
Since initially E15 may be introduced
into commerce in a limited geographical
area, it may not be necessary to carry
out the full survey or to carry it out
nationwide. One way to potentially
resolve this issue would be to limit the
areas required to be surveyed to areas
that are known to have E15 being
distributed. Unfortunately, there are no
reliable real-time data that show when
E15 is first introduced into an area and
it could take awhile for the proposed
annual survey program to incorporate
these new geographic areas.
Additionally, the borders of such areas
are difficult to define and constantly
shift in response to market forces. This
approach also undermines one of the
stated purposes of the survey program,
namely that the survey program helps
deter either intentional or unintentional
violations by increasing the likelihood
of violators being randomly caught. If
EPA allows only certain areas to be
surveyed while excluding others, some
parties may manufacturer, blend, or
distribute E15 without properly
identifying the fuel as E15 or properly
labeling the fuel dispenser as dispensing
E15. By the time the survey program
caught up, motor vehicles and nonroad
products not approved for E15 use may
have been misfueled for a long time. On
the other hand, if there were ways to
properly identify areas that are
distributing E15 real time, then limiting
the survey to only those areas could
considerably reduce the cost of
compliance with the proposed survey
requirements. The Agency seeks
comment on ways to possibly limit
surveys to only those areas that have
E15 being introduced into commerce.
Another option to limit survey
requirements would be to require a
national survey, but have a lower
minimum sample size that gradually
increases over time. Since the proposed
approach for determining sample sizes
above 7,500 discussed above is based on
the proportion of retail stations that are
noncompliant with ethanol content and/
or E15 labeling requirements, if there is
very little E15 being introduced into the
marketplace, the proportion of
noncompliant retail stations would be
small. In this case, 7,500 samples may
be substantially higher than the number
of samples required by the proposed
method for determining sample sizes.
Since this is most likely to occur at the
beginning of the survey program, the
survey program could gradually
increase the annual minimum sample

size to reduce the burden to industry.
For example, the Agency may only
require a minimum of 2,000 samples the
first full survey year (2012), 4,000
samples in 2013, 6,000 samples in 2014,
and 7,500 samples in 2015. We seek
comment on this gradual minimum
sample size approach and all other
issues related to determining the
minimum number of samples for a
national ethanol content and E15
labeling survey.
We also are proposing that the
independent survey association would
ship fuel samples on the same day that
the sample was collected and that the
sample be analyzed for ethanol content
within 24 hours from the time the
samples were acquired. Although
having such a short delivery time for
fuel samples to be analyzed may
increase costs, this time period is both
consistent with other fuel survey
programs and would allow ethanol
content and E15 labeling violations
found by the survey to be corrected
quickly to mitigate misfueling. We seek
comment on the proposed amount of
time allowed for samples to be shipped
for the analysis of ethanol content.
For both survey options, we require
that survey plans would include a
methodology for determining when the
survey samples will be collected, the
locations of the retail outlets where the
samples will be collected, the number of
samples to be included in the survey,
procedures that would prevent the
advance notification of retail stations,
and how individual retail stations will
be determined for sampling. We propose
that samples at retail stations be taken
from all gasoline dispensers and have
the samples tested for ethanol content
and that retail stations be selected
randomly with the probability of
selection proportionate to the volume of
gasoline sold at the retail outlet. We also
propose that ethanol content be
measured in accordance with a test
method that meets the requirement of 40
CFR 80.46(g). We seek comment on
these requirements for survey plans and
whether any additional requirements
are necessary. We also seek comment on
all matters related to the national
ethanol content and E15 labeling survey
proposed today.
D. Program Outreach
Effective outreach to consumers and
stakeholders is often essential to the
successful implementation of
environmental protection programs. To
implement the RFS program, for
example, EPA provides training
seminars for stakeholders and manages
dedicated telephone and e-mail support
lines. Various industry representatives
VerDate Mar<15>2010
18:04 Nov 03, 2010
Jkt 223001
and organizations provided program
information and coordination to their
members and customers as well as to
facilitate the introduction of new
program requirements this past July.
In the case of E15, outreach to
consumers and stakeholders may be
critical to help mitigate misfueling
incidents that can result in increased
emissions or vehicle or engine damage.
The potential for E15 misfueling
incidents exists because consumers tend
to choose the lowest priced fuel, and
E15 may cost less than E10 since
ethanol currently tends to be less
expensive than gasoline.
A recent example of successful
outreach to consumers and stakeholders
is the coordinated work done in support
of the ULSD program. ULSD was a new
fuel with the possibility of consumer
misfueling that could result in engine
damage. With ULSD, the fuel industry
trade association API took the lead in
working with stakeholders to establish
the Clean Diesel Fuel Alliance (CDFA),
a collaboration of public and private
organizations designed to ensure a
smooth program transition by providing
comprehensive information and
technical coordination. The
organizations represented in the CDFA
include engine manufacturers, fuel
retailers, trucking fleets, DOE and EPA.
CDFA efforts to educate ULSD users
include developing technical guidance
and educational information, including
a Web site (https://www.clean-diesel.org),
as well as serving as a central point of
contact to address ULSD-related
questions.
The CDFA outreach model could
prove beneficial in this case. EPA
anticipates that all parties that may be
involved in bringing higher gasolineethanol blends to market would
participate in a coordinated industry-led
consumer education and outreach effort.
In the context of this program, potential
key participants include ethanol
producers, fuel manufacturers,
automobile, engine and equipment
manufacturers, States, nongovernmental organizations, parties in
the fuel distribution system, EPA, DOE,
and USDA. Potential education and
outreach activities a public/private
group could undertake include serving
as a central clearinghouse for technical
questions about E15 and its use,
promoting best practices to educate
consumers or mitigate misfueling
instances, and developing educational
materials and making them available to
the public.
Some stakeholders have also
suggested that a Web site be created to
inform consumers of the potential
impacts of E15 on older motor vehicles,
PO 00000
Frm 00014
Fmt 4701
Sfmt 4702
heavy-duty gasoline engines and
vehicles, motorcycles, and nonroad
products. Stakeholders have further
suggested that, if a unique misfueling
Web site is created, then EPA should
require the Web site address to be
displayed on the E15 label. EPA seeks
comment on the appropriateness of a
unique misfueling Web site and of
including such a Web site address on
the E15 label.
E. What other means of mitigating
misfueling were considered?
EPA believes that the proposed
misfueling mitigation approach will
effectively and sufficiently mitigate
misfueling based on our past
experience. The Agency employed a
similar and relevant misfueling
mitigation program when ULSD was
introduced in 2006. Retail stations and
wholesale purchaser-consumers were
required to have fuel dispenser labels
indicating whether the diesel being
dispensed was 500 ppm (low sulfur
diesel or LSD) or 15 ppm (ULSD).
MY2007 and newer on-highway diesel
vehicles and engines were required to
use ULSD and prohibited from using
LSD. At the beginning of the ULSD
program, we were aware of several
instances where consumers, after
checking the labels, had difficulty
finding ULSD in some areas. Consumers
were informed that misfueling would
result in significant engine damage. We
are not aware of any significant
instances when misfueling occurred
during this labeling program. This
indicates that EPA outreach and
information provided by the engine
manufacturers, Clean Diesel Fuel
Alliance, and other stakeholders, was
effective in educating consumers and
mitigating misfueling. Additionally, we
feel that product transfer document
requirements and the ULSD survey
program were vital in implementing and
enforcing this fuel transition. Based on
the success of the ULSD program, we
believe that similar requirements for
E15 will be sufficient and successful.
Some have argued that the ULSD
program example is not applicable in
this case since the MY2007 and newer
on-highway diesel vehicles and engines
were at risk from misfueling, whereas
for E15, it is primarily older motor
vehicles (i.e., MY2000 and older motor
vehicles) that are at risk. While EPA
believes that the potential for engine
repair costs applies in both cases, the
Agency also believes that similar
misfueling mitigation measures can be
effective for E15 as well. Coupled with
an effective outreach and public
education program, the proposed
mitigation measures should deter

srobinson on DSKHWCL6B1PROD with PROPOSALS2
Federal Register / Vol. 75, No. 213 / Thursday, November 4, 2010 / Proposed Rules
misfueling and encourage consumers to
pay close attention to the E15 labels.
Some have also argued that the ULSD
program is not applicable because the
ULSD program focused primarily on
commercial truck drivers, who may be
more cognizant of fuel choices due to
the potential impact on their
commercial investments, than the
general public. We believe that
consumers are also concerned about
their private vehicles, and that the
potential costs associated with
misfueling (discussed below in section
III.F) will have just as much of an
impact in informing consumer fuel
choices. As long as fuel dispensers are
properly labeled and consumers are
adequately informed of the associated
risks of misfueling nonroad products
and older motor vehicles on E15, we
believe the proposed misfueling
mitigation program will be effective.
While EPA believes that the
misfueling mitigation provisions
included in today’s proposal will
address potential misfueling concerns,
we recognize that these provisions are
not the only potential means for
addressing misfueling concerns. EPA
has received many suggestions for
mitigating misfueling. For example, API
conducted a scoping study, ‘‘Evaluation
of Measures to Mitigate Misfueling of
Mid- to High-Ethanol Blend Fuels at
Fuel Dispensing Facilities,’’ that
includes many of these suggestions.
That study may be found in the
docket.26
One suggestion in API’s study was to
have full service attendants at gas
stations that ensure E15 is only used in
appropriate motor vehicles. While such
a measure may be effective, its overall
effectiveness is unknown and it would
be a large burden on service stations to
employ service attendants for this
purpose. This option would come at an
extremely large cost, and there would
need to be significant training of new
employees. API estimates the average
annual cost per service station at
$67,500 and the annual nationwide cost
at $10.6 billion. Another suggestion was
to have separate islands at service
stations, with one for blends at E10 and
below, and one for mid- and highgasoline-ethanol blends. It was noted
that this measure would also likely
cause congestion at the pumps, be
inconvenient for the consumer, reduce
the number of pumps available for
higher-demand fuels, and not prevent
intentional misfueling. API estimates

Measures to Mitigate Misfueling of Mid- to HighEthanol Blend Fuels at Fuel Dispensing Facilities,’’

Jkt 223001
the cost of separate islands at $700 per
station and $40 million nationwide,
though they did not cost out the
consumer implications.
Another option discussed is a
measure in which keypads or
touchscreens would be made available
at each pump to allow consumers to
input data about their motor vehicle or
simply answer ‘‘yes’’ or ‘‘no’’ to the
question of whether their motor vehicle
is an FFV or non-FFV. If the motor
vehicle is appropriate for the fuel, then
the pump would allow fueling. If
existing dispensers do not already have
display screens, this strategy would
require retail stations to install keypads
or touchscreens at an approximate cost
of $5,000 for dispensers that may be
retrofitted, with the cost prohibitive for
dispensers that may not be retrofitted.
There may also be an additional cost per
station of $10,000—$20,000 to install a
central controller to accept motor
vehicle information. Such a strategy
may cause some congestion at the
pumps. Intentional misfueling would
not be prevented through such measure.
Also discussed in the report was a
strategy in which retail stations would
have a video or audio presentation play
when a mid- to high- gasoline-ethanol
blend pump is lifted from the dispenser.
The presentation would provide
information to the consumer about
E10+, which motor vehicles may fuel
with it, and why other motor vehicles
should not. Optionally, the consumer
could be required to confirm fueling
with E10+ at the end of the
presentation. The cost of such an
alternative for those stations without
display screens, is estimated to be
$5,000; if the existing dispenser could
not be retrofitted with a display screen,
there would be additional and
considerable costs incurred for
replacing a dispenser. Costs for this
option could be as high as $20,000 per
station.
API also suggested that a different
colored hand warmer or a different type
of nozzle grip for fuel pumps with E15+
may help alert consumers to the new
type of fuel without a large burden on
retail stations. Hand nozzles for E15+
would be a different color than for other
gasoline types, or would have a different
texture from other hand grips. To be
effective, one color or one type of grip
should be used for E15+ on a national
basis. Consumers would know by the
color and/or texture that those pumps
were for E15+. Some concerns about
this option are that it would not be
possible to distinguish nozzles that
dispense both E10 and E15, some
consumers may not notice the warmer
or grip, and this would not prevent
PO 00000
Frm 00015
Fmt 4701
Sfmt 4702
68057
intentional misfueling. However, API
believes that nozzle grips with different
textures would be noticeable to most
consumers, even those who do not read
the pump labels. Also, hand nozzle
grips are easy to install and replace as
needed. API has estimated the cost at $5
to $11 per nozzle with a national cost
of $800,000 to $1.6 million.
While many of the strategies
discussed in the API study may be
effective in communicating with the
consumer about E15, EPA believes that
the combination of pump labels,
regulatory prohibition on misfueling,
PTDs, a survey, and consumer outreach
will adequately mitigate misfueling by
consumers. The labels on the fuel
pumps will notify consumers that the
pump is for E15 and only certain MY
motor vehicles should use that fuel.
Consumer outreach will give the
consumer more in-depth information,
such as why older MY motor vehicles,
heavy-duty gasoline engines and
vehicles, motorcycles, and nonroad
products should not fuel with E15 and
what damage may occur from
misfueling. The PTDs will help ensure
that E15 is identified as such through
the distribution chain, which will help
prevent inadvertent mislabeling of fuel.
Finally, a survey will identify where
mislabeling (or no labeling) of E15 has
occurred so that appropriate labels are
used.
Other options that have been
suggested may be too expensive,
difficult to implement, and/or otherwise
not likely acceptable to consumers. As
such, EPA does not deem it appropriate
to include these options in today’s
proposal. We seek comment on any
other measures not proposed in the rule
that the regulated industries and other
interested parties feel may be necessary
to mitigate misfueling. We seek
comment on any other cost-effective
mitigation measures that may be
appropriate. If EPA considers requiring
any other mitigation measures that are
suggested by commenters in the final
rule, EPA will conduct appropriate
analyses of such measures, including
the impacts on small businesses, before
deciding whether to include such
mitigation measures in the final rule.
F. Cost of Compliance
The cost of compliance with the
provisions being proposed today
include the periodic capital costs of
labeling fuel dispensers, the onetime
costs of the PTD requirements, and the
annual cost of the survey requirements.
The cost of the proposed labeling
requirements is estimated at $1.04
million per year on an annualized basis.
The cost of the proposed PTD

requirements is estimated at $0.56
million per year on an annualized basis.
The cost of the proposed survey
requirements is estimated at $2.05
million per year. The total cost of all of
the proposed requirements is estimated
at $3.65 million per year. These
estimated costs are detailed in the
following sections. As discussed in
section III.F.4, we believe that these
costs will be more than offset by the
avoided costs of repairing engines/
vehicles that could otherwise have been
damaged by misfueling in the absence of
the implementation of the proposed
requirements.

1. Labeling Costs
Our estimate of the cost of the
proposed E15 fuel dispenser labeling
requirement includes the cost to the fuel
retailer of purchasing the label, the
administrative cost to ensure that all
gasoline dispensers are labeled
appropriately, and the labor cost to
replace fuel dispenser labels. Based on
our past experience with labeling
programs, the RFS2 NPRM and industry
input, the cost of an E15 label is
estimated to be $5.00 per label.27 There
are approximately 162,000 retail gas
stations in the U.S. according to
National Petroleum News.28 The RFS2
Final RIA estimates that there is an
average of 7.7 gasoline refueling
positions per retail station.29 Thus, for
a retail facility that has 8 refueling
positions, the total cost if all of the
dispenser labels are replaced would be
$40.00. A number of fuel retailers are
small businesses. However, we believe
that the minor cost of label replacement
would not represent a significant
additional burden to any fuel retailer.
Specifically, making the conservative
assumption that there will be the
maximum number of pumps (8) even for
small stations and assuming an 8 year
life before labels need to be replaced,
the annualized cost to a service station
is $5 per year. The amount of gasoline
sold at a small service station is
estimated to be approximately 60,000
gallons/month.30 Assuming an average
cost of gasoline at $2.31/gal (per the EIA
2009 national average regular grade

gasoline price) the annual revenue for a
small service station from its gasoline
sales is approximately $1.7 million.31
Thus, the cost of the labels represents
less than 0.001% of the total annual
revenue of a small gas station from its
gasoline sales.32
Although we are requesting comment
on whether all gasoline fuel dispensers
should be labeled,33 today’s notice only
includes proposed labeling
requirements for E15 fuel dispensers.
Nevertheless, we are assuming all
gasoline refueling positions would be
relabeled for the purposes of estimating
the costs of this proposal. This approach
provides a conservatively high estimate
of costs if only the proposed E15
labeling requirements are finalized. By
multiplying the average number of
gasoline refueling positions per retail
facility, by the number of fuel retailers,
and the cost per label, we arrived at an
estimated cost of $6.23 million to
replace all of the labels at gasoline
refueling positions at all fuel retailers in
the U.S. We assumed an 8 year label life
before it needs to be replaced.
Amortizing the periodic labeling costs
using a 7% cost of capital, we estimate
the annualized cost to comply with the
proposed labeling provisions to be
approximately $1.04 million per year.
We request comments on these
estimated costs.
proposed PTD requirements. We request
comment on these estimated costs.
3. Survey Costs
The estimated costs of the proposed
ethanol content and labeling survey are
based on experience with the existing
RFG and ULSD surveys and discussions
with industry. The RFG survey includes
all of the elements required in the
proposed nationwide survey except the
survey of compliance with the proposed
labeling requirements. We estimate that
the cost of adding the proposed survey
of compliance with the proposed
labeling requirements to the existing
RFG survey at $50,000 per year. The
cost to implement all of the proposed
survey provisions for conventional
gasoline is estimated at $2 million per
year. Thus, the total cost of the
proposed survey requirements is
estimated to be $2.05 million per year.35
We request comments on this estimate.
4. Avoided Motor Vehicle and Nonroad
Product Repair Costs
We believe that proposed labeling and
associated survey and PTD provisions
will be an effective tool at mitigating
unintentional misfueling based on our
experience with other labeling
provisions (such as ULSD). The
resulting prevention of misfueling will
not only minimize the potential
emission increases that could result (as

request comment on this assessment.
G. Compliance and Enforcement
srobinson on DSKHWCL6B1PROD with PROPOSALS2
1. What are the prohibited acts?
There is a long-standing prohibition,
under CAA section 211(f)(1), that fuel
manufacturers may not introduce
gasoline-ethanol blends containing
greater than 10 vol% ethanol into
commerce for use in non-flex-fuel
vehicles. The partial waiver modifies
this prohibition so that gasoline-ethanol
blends containing up to 15 vol%
ethanol may legally be introduced into
commerce by fuel manufacturers for use
in MY2007 and later light-duty motor
vehicles. The waiver does not apply to
any MY heavy-duty gasoline engine or
vehicle, motorcycle, or nonroad
product.
We are proposing that all parties
would be prohibited from selling,
introducing into commerce or causing
or allowing the sale or introduction into
commerce of gasoline that has an
ethanol content above 10 vol% ethanol
into MY 2000 and older light-duty
motor vehicles, any heavy-duty gasoline
engine or vehicle, any motorcycle, and
any nonroad product. We are also
proposing that fuel distributors who
transport or store a gasoline-ethanol
blend, base gasoline or blendstock for
ethanol blending would be prohibited
from increasing the ethanol content to
exceed the value noted on the PTD.37
Since the Agency is deferring a decision
for MY2001–2006 motor vehicles, we
are not proposing a prohibition for fuel
used in these motor vehicles at this
time. DOE testing of MY2001–2006
light-duty motor vehicles is ongoing and
EPA expects to make a waiver
determination for these vehicles shortly
after the results of the DOE testing are
available. If EPA does not grant an E15
waiver for MY2001–2006 light-duty
motor vehicles, then we would expect to
include the same prohibitions for these
MY motor vehicles in the final
rulemaking. Even though we are not
proposing an actual prohibition for
motor vehicles MY2001–2006, it is still
unlawful for fuel manufacturers to
introduce E15 into commerce for use in

these motor vehicles unless we grant an
E15 waiver for these motor vehicles.
In addition to this general misfueling
prohibition, there are several other
prohibited acts that we are proposing in
conjunction with the regulatory
provisions being proposed today. We
are proposing that retailers and
wholesale purchaser consumers would
be prohibited from dispensing E15
unless they comply with the proposed
dispenser labeling requirements in
section III.A. of today’s preamble. We
are proposing that ethanol blenders
would be prohibited from introducing
E15 into commerce without complying
with the proposed ethanol content
survey requirements in section III.C. of
today’s preamble.
In addition, there are several RVP
related prohibitions that exist today that
may need to be modified in light of E15.
There is an existing prohibition with
respect to exceeding applicable
summertime RVP requirements.38 We
are proposing to prohibit the
commingling of an E10 gasoline-ethanol
blend with either E0 or E15 due to
potential concerns about causing a
violation of summertime RVP
requirements unless the E10 blend had
not taken advantage of the 1 psi RVP
waiver. For the same reasons,
prohibitions on the commingling of
BOBs is necessary. Therefore we are
proposing certain prohibitions against
commingling conventional gasoline
BOBs similar to the prohibitions for
reformulated blendstocks for oxygenate
blending (RBOBs) in 40 CFR 80.78
under the RFG program. Specifically,
we are proposing to prohibit
commingling an E10 BOB (produced to
take advantage of the 1 psi RVP waiver)
with an E15 BOB unless the resulting
mixture is designated as an E10 BOB.
We request comment on whether other
modifications to these existing RVP
related regulatory requirements are
needed as a result of the introduction of
E15.
2. What are the proposed liability and
penalty provisions for noncompliance?
Today’s proposed rule contains
prohibition and liability provisions that
are similar to those of the other fuels
programs in 40 CFR Part 80.39 Under the
proposed regulation, regulated parties
would be liable for committing certain

section 80.23 (liability for lead violations); section

(liability for violation of RFG prohibited acts);
section 80.80 (penalties for RFG/CG violations);
section 80.395 (liability for gasoline sulfur
violations); section 80.405 (penalties for gasoline

prohibited acts, such as selling or
distributing gasoline-ethanol blends
with an ethanol content that exceeds the
maximum for the intended end-use
category of vehicles/engines, or causing/
contributing to others committing
prohibited acts. In addition, parties
would be liable for a failure to meet
certain affirmative requirements or
causing others to fail to meet their
affirmative requirements. All parties in
the fuel distribution system would be
liable for a failure to fulfill the
recordkeeping and PTD requirements.
a. Presumptive Liability
All EPA fuels programs include a
presumptive liability scheme for
violations of prohibited acts. Under this
approach, liability is imposed on two
types of parties: (1) The party in the fuel
distribution system that controls the
facility where the violation was found
or has occurred; and (2) those parties,
typically upstream in the fuel
distribution system from the initially
listed party (such as any distributor of
the fuel), whose prohibited activities
could have caused the program
nonconformity to exist.40 This
presumptive liability scheme has
worked well in enabling us to enforce
our fuels programs since it creates
comprehensive liability for essentially
all the potentially responsible parties.
The presumptions of liability may be
rebutted by establishing an affirmative
defense.
To clarify the inclusive nature of
these presumptive liability schemes,
today’s proposed rule would explicitly
include as prohibitions causing another
person to commit a prohibited act and
causing the presence of a nonconforming gasoline-ethanol blend
(such as a blend designated as
containing less than 15 vol% ethanol
which actually contains a greater
concentration of ethanol) to be in the
distribution system. This is consistent
with the provisions and implementation
of other fuels programs.
Today’s proposed rule, therefore,
provides that most parties involved in
the chain of distribution would be
subject to a presumption of liability for
committing prohibited actions and
causing violations by other parties. For
example, an ethanol blender could be
held presumptively liable for causing a
gasoline-ethanol blend that exceeds the
maximum ethanol content stated on the
product’s PTD to be present in the
distribution system unless the blender
provides an affirmative defense to
40 An additional type of liability, vicarious
liability, is also imposed on branded refiners under
these fuels programs.

demonstrate that it did not cause the
exceedance. An ethanol blender could
cause such an exceedance by adding too
much ethanol to a blend or making an
error on the PTD that they prepare. An
ethanol manufacturer could be held
presumptively liability for causing an
exceedance of the maximum ethanol
content requirements unless it could
demonstrate that the ethanol it
produced could not have caused the
downstream violation.41 Like other fuels
regulations, a refiner also would be
subject to a presumption of vicarious
liability for violations by any
downstream facility that displays the
refiner’s brand name, based on the
refiner’s ability to exercise control at
these facilities. Carriers, however,
would be liable only for violations
arising from product under their control
or custody and not for causing nonconforming gasoline to be in the
distribution system, except where
specific evidence of causation exists. A
carrier might cause an exceedance of the
ethanol content stated on the PTD for
product in its custody by commingling
products with dissimilar ethanol
contents. For example, a carrier might
cause the ethanol content of a product
designated as E15 to exceed 15 vol%
ethanol by transporting the product in a
tank truck that had previously
transported E85 that had not been
properly drained.

b. Affirmative Defenses for Liable
Parties
This proposal also includes
affirmative defenses for each party that
is deemed liable for a violation.
Additionally, all presumptions of
liability are rebuttable. The proposed
defenses are similar to the defenses
available to parties for violations of the
RFG and diesel sulfur regulations. We
believe that these defense elements set
forth reasonably attainable criteria to
rebut a presumption of liability. We are
proposing that the affirmative defense
require a party to demonstrate all of the
following: (1) The party did not commit
or cause the violation; (2) the party has
PTDs indicating that the fuel was in
compliance at its facility; and (3) except
for retailers and wholesale purchaserconsumers, the party conducted a
quality assurance program. For parties
other than tank truck carriers, we are
proposing that the quality assurance
program would be required to include
periodic sampling and testing of
gasoline-ethanol blends for their ethanol

cause a downstream exceedance of maximum
ethanol content requirements if they did not add
the required amount of denaturant.

content. For tank truck carriers, we are
proposing that the quality assurance
program would not need to include
periodic sampling and testing of the
gasoline-ethanol blend, but in lieu of
sampling and testing, the carrier would
be required to demonstrate evidence of
an oversight program for monitoring
compliance, such as appropriate
guidance to drivers on compliance with
applicable requirements and the
periodic review of records concerning
the quality of gasoline-ethanol blends
and their delivery.
With respect to the assessment of
liability for the introduction of E15 into
any engines, vehicles or equipment that
are not covered by the partial waiver for
use of E15, EPA would typically not
hold a self-service fuel retailer liable for
customer misfueling if the retailer has
labeled their dispensers appropriately
and did not condone or facilitate such
misfueling.
We are proposing that participation in
the ethanol content survey could be
used to meet some or all of the periodic
sampling and testing elements of a
regulated party’s (e.g. branded refiners,
ethanol blenders, and fuel distributors)
affirmative defenses to presumptive
liability in cases where instances of
noncompliance with the applicable
maximum ethanol content specification
are discovered.42 In addition to
participation in the survey, we are
proposing that ethanol blenders would
be required to periodically test the
accuracy of their equipment/methods
used to add ethanol to gasoline. We are
proposing that all other regulated
parties could satisfy all of the periodic
sampling and testing elements of their
affirmative defenses to presumptive
liability by participating in the survey.
As in other fuel regulations, branded
refiners would be subject to more
stringent standards for establishing a
defense because of the control such
refiners have over branded downstream
parties. Under today’s rule, in addition
to other presumptive liability defense
elements, we are proposing that branded
refiners would also be required to show
that the violation was caused by an
action by another person in violation of
law, an action by another person in
violation of a contractual agreement
with the refiner, or the action of a
distributor not subject to a contract with
the refiner for the transportation of the
gasoline.
Based on experience with other fuels
programs, we believe that a presumptive
liability approach would increase the

likelihood of identifying persons who
cause violations of the prohibited acts in
today’s proposal. We normally do not
have the information necessary to
establish the cause of a violation found
at a downstream facility. We believe
that those persons who actually handle
the fuel are in the best position to
identify the cause of the violation, and
that a rebuttable presumption of liability
would provide an incentive for parties
to be forthcoming with information
regarding the cause of the violation. In
addition to identifying the party that
caused the violation, providing
evidence to rebut a presumption of
liability would serve to establish a
defense for the parties that are not
responsible. Presumptive liability is
familiar to both the petroleum industry
and EPA, and we believe that this
approach would make the most efficient
use of EPA’s enforcement resources. For
these reasons we are proposing a
liability scheme based on a presumption
of liability. We request comment on the
proposed liability provisions.
c. Penalties for Violations
CAA section 211(d)(1) provides for
penalties for violations of the fuels
regulations. These penalty provisions
subject any person that violates any
requirement or prohibition of the rule to
a civil penalty of up to $27,500 for every
day of each such violation and the
amount of economic benefit or savings
resulting from the violation. Pursuant to
40 CFR 19.4, the amounts of civil
penalties for these violations increased
to $37,500 per day, plus the amount of
any economic benefit or savings
resulting from the violation, for
violations that occurred after January
12, 2009. Today’s proposal would
subject any person who violates any of
the proposed requirements or
prohibitions to a civil penalty up to
$37,500 for every day of each such
violation and the amount of the
economic benefit or savings resulting
from the violation.
We propose that a violation of the
requirements in today’s notice would
constitute a separate day of violation for
each day the gasoline giving rise to the
violation remains in the fuel’s
distribution system. The length of time
the gasoline in question remains in the
distribution system would be deemed to
be twenty-five days unless there is
evidence that the fuel remained in its
distribution system a lesser or greater
amount of time. These proposed penalty
provisions are similar to those in the
RFG, Tier 2 sulfur, and diesel sulfur
programs. We request comment on the
proposed penalty provisions.

IV. Other Measures To Ensure
Compliance
srobinson on DSKHWCL6B1PROD with PROPOSALS2
A. The 1.0 psi RVP Waiver for E10
Blends
One concern that was raised in the
comment periods on the E15 waiver and
RFS2 NPRM in addition to stakeholder
meetings prior to this proposal was
whether E15 would qualify for the
1.0 psi RVP waiver permitted under the
Clean Air Act (CAA) section 211(h) for
conventional gasoline. As discussed in
the partial waiver decision document,
we believe that E15 blends with higher
volatility would cause vehicles to
violate their evaporative emission
standards in-use. Consequently, the
waiver announced today is for E15
blends that meet the summertime
gasoline volatility standards for
conventional gasoline without any
1.0 psi RVP waiver, and the regulatory
provisions proposed today reflect this
decision. Furthermore, EPA interprets
section 211(h)(4) of the CAA as limiting
the 1.0 psi waiver to gasoline-ethanol
blends that contain 10 vol% ethanol,
including limiting the provision
concerning ‘‘deemed to be in full
compliance’’ to the same 10 vol%
blends. EPA implemented CAA section
211(h)(4) through 40 CFR 80.27(d)
which provides that gasoline-ethanol
blends that contain at least 9 vol%
ethanol and not more than 10 vol%
ethanol qualify for the 1.0 psi waiver of
the applicable RVP standard.
Nevertheless, we seek comment on
whether section 211(h) of the CAA
could be interpreted such that E15 is
eligible for the RVP provisions in
section 211(h)(4) and whether this
would have any impact on our E15
waiver decision.
In order to introduce a fuel that meets
both the Federal summertime RVP
standards and contains between 10 and
15 vol% ethanol, fuel refiners would
have to create a fuel or blendstock that
has approximately 1.0 psi lower RVP
than a fuel or blendstock intended for
E10 due to the interaction between
gasoline volatility and ethanol when
blended. Oxygenate blenders would
need to know the RVP of a blendstock
or have the intended ethanol content of
a blendstock be specified on the PTD to
ensure that they know the correct
amount of ethanol that should be
blended into a fuel. If an oxygenate
blender or retail station blended more
than 10 vol% ethanol into a fuel or
blendstock produced with the
expectation of taking advantage of the
1 psi waiver that applies to E10, the
resulting blend would be in violation of
summertime RVP standards.
VerDate Mar<15>2010
18:04 Nov 03, 2010
Jkt 223001
68061
Having E10 and E15 at different RVP
levels in-use also raises the potential
that mixtures of the two at retail would
cause the blend to exceed the
summertime RVP requirements. Many
retail stations only have two
underground storage tanks and those
tanks typically contain regular and
premium grade fuels. Since, in many
cases, midgrade gasoline is made by
blending regular and premium grade
gasoline, the possibility exists that a
midgrade fuel blended from a high-RVP
E10 fuel and a low-RVP E15 fuel would
exceed summertime RVP requirements.
This fuel would not receive the 1.0 psi
RVP waiver and selling such a fuel
would violate RVP requirements.
These RVP related complications
could be avoided by refiners producing
a lower RVP blendstock for E10 as well.
While there are cost and supply
considerations refiners and fuel
distributors may find it in their best
interest to do so given the flexibility it
affords. Regardless, the Agency believes
that it would be possible to help
alleviate some of these challenges with
the slight modifications to the PTDs and
the national fuel survey requirements
discussed in Section III of this proposal.
RFG already has similar requirements to
those that we are proposing in today’s
rulemaking, and given the effectiveness
we have had with the RFG program, we
believe that the proposed approach
would be an effective means of allowing
fuel manufacturers to ensure that the
correct amount of ethanol was blended
into the appropriate blendstock or
finished fuel with only slight additions
at minimal costs. We believe that these
PTD proposals are appropriate under
our authority under sections 208 and
114 of the Clean Air Act.
and help provide an affirmative defense
for upstream parties in the event of a
violation downstream. We seek
comment on whether RVP survey
requirements should be included as part
of the national ethanol survey proposed
in section III.C.
1. National RVP Survey
B. Credit for RFG Downstream
Oxygenate Blending
Pursuant to 40 CFR 80.69, refiners of
RBOB are permitted to take credit for
downstream oxygenate blending toward
compliance with RFG standards. To do
so the refiner must direct the
downstream oxygenate blender on the
PTD to add a particular type and
amount of oxygenate. However, these
provisions may require some
reconsideration. In light of the addition
of E15 to the RFG marketplace, it may
be more difficult to ensure that 15 vol%
ethanol is in fact added downstream if
the RBOB would also meet all other
finished gasoline specifications with the
addition of just 10 vol% ethanol.
Oxygenate blenders could also be left in
the untenable position of having a
supply of RBOB for E15 blending and an
inability to blend more than 10 vol%
In section III.C., we described our
proposal for a national E15 labeling and
ethanol content survey that is intended
to ensure that fuel pumps would be
properly labeled if retail stations chose
to sell E15. In order to determine if the
proposed labeling requirements are
being met and the ethanol content is
consistent with the label, fuel sampling
and testing would be required to
determine the ethanol content. Since
fuel refiners will have difficulty
ensuring that downstream summertime
RVP requirements are met in non-RFG
areas, adding testing for RVP to this
survey would be a low-cost 43 approach
to enforcing downstream RVP standards
43 Based EPA discussions with industry, the costs
of for RVP survey requirements as part of the E15
labeling survey would add approximately $200,000
dollars per year to the total costs of the survey.

2. RVP and E15 Underground Storage
Tank Transition
Another issue associated with the
RVP standards is the potential
comingling of a higher RVP E10 fuel
that received the 1.0 psi RVP waiver
with a lower RVP E15 that met
summertime RVP requirements in
underground storage tanks when a retail
station decides to transition from selling
E10 to E15. If the retail station does not
completely remove all E10 from a tank
before E15 is added to the tank, the
retail station would create a fuel that
violates RVP standards. The resulting
blend would be above 10 vol% ethanol
and would not qualify for the 1.0 psi
waiver, but would have an RVP above
the requirement for E0 and E15.
Section 211(t) of the Clean Air Act, as
amended by the Energy Policy Act of
2005, allows retail stations to blend
compliant RFG batches of non-ethanol
blended and ethanol-blended gasoline
in storage tanks twice a year as long as
the duration of the blended period is no
longer than 10 consecutive calendar
days. However, the authority granted to
the Agency for the transition of fuels in
underground storage tanks was
specifically limited to that case and we
do not believe this provision authorizes
a blending down of E10 and E15 over
time in non-RFG areas.
We seek comment on the issue of tank
transition from E10 to E15 fuels and if
there are ways that the Agency could
address this issue.

V. Modification of the Complex Model
A. Background of RFG Requirements
Reformulated gasoline (RFG) is
gasoline that is required to be sold in
certain parts of the country, and is
required to be reformulated to meet
certain performance standards for
emissions of smog forming and toxic air
pollutants. In 1990 Congress amended
the CAA to require that RFG be sold in
cities with the worst ozone pollution
problems. In addition, other cities with
significant smog problems were
provided the opportunity to voluntarily
opt-in to the RFG program. RFG is
currently used in portions of 17 States
and the District of Columbia. About
30% of gasoline sold in the U.S. is
reformulated. In the 1990 Amendments,
Congress also required that
conventional gasoline (CG, or non-RFG)
sold in the rest of the country become
no more polluting than gasoline sold in
1990. Often referred to as ‘‘antidumping’’, this requirement ensures that
refiners do not ‘‘dump’’ into
conventional gasoline fuel components
that are restricted in RFG and that
increase environmentally harmful
emissions.
EPA introduced the RFG program in
1995, as required by the CAA. The RFG
program established emissions
performance standards for volatile
organic compounds (VOCs), nitrogen
oxides (NOX), and toxics. These
standards are based on percent
reductions from the average emissions
of these pollutants in 1990 model year
vehicles operated on a specified
baseline gasoline. The program required
an oxygen minimum standard of 2.0%
by weight, however the Energy Policy
Act of 2005 removed that requirement.
For conventional gasoline, the program
establishes emissions standards for
exhaust toxics and NOX designed to
ensure that an individual refinery’s or
importer’s gasoline will not have higher
levels of these pollutants than the
refinery’s or importer’s 1990 gasoline.
Refiners of RFG must comply with the
RFG standards separately for each
VerDate Mar<15>2010

Jkt 223001
refinery. Refiners of conventional
gasoline may comply separately for each
refinery, or they may aggregate their
refineries. Importers comply with both
the RFG and conventional gasoline
standards for the aggregate of the
gasoline they import during the year.
B. The Complex Model
To measure compliance with the RFG
and anti-dumping standards, the
emissions performance of gasoline is
calculated using a model, called the
Complex Model, which predicts the
emissions level of each regulated
pollutant based on the measured values
of certain gasoline properties. These
properties are: Aromatics, olefins,
sulfur, Reid Vapor Pressure (RVP),
benzene, oxygen and distillation points,
as well as the content of ethanol, ETBE,
TAME and MTBE. Refiners and
importers are required to measure these
properties in each batch of gasoline they
produce or import, using a prescribed
test method, and calculate the emissions
level of each pollutant for each batch of
gasoline using the Complex Model. The
emissions level as computed by the
Complex Model is compared to the
baseline emissions for each pollutant,
and the percent reduction is then
calculated. The standards for VOC, NOX
and toxics are stated in terms of percent
reductions from the baseline. Thus, for
fuel to comply with the standards, the
percent reduction computed by the
Complex Model must be equal to or
greater than the standard for each
pollutant. Under the Clean Air Act,
baseline emissions must be based on
1990 vehicle technology, not current
fleets, nor off-road equipment.
For gasoline to be sold in the U.S., it
must comply with the standards.
Refiners are therefore required to certify
that their fuel meets the standards by
using the Complex Model. Currently,
the equations in the model are limited
to an oxygen content of no more than
4.0% by weight in gasoline, which is the
maximum amount of oxygen in gasoline
containing 10 vol% ethanol, or E10.44 In
order for refiners to produce gasoline
that will contain 15 vol% ethanol, the
model must be modified to predict the
effect of the additional oxygen.
The applicability of the Complex
Model to gasoline certification has
become limited as EPA’s more recent
clean gasoline standards take effect and
provide even greater emission
reductions beyond those of the RFG
44 Because
the percent by weight of oxygen in the
fuel varies depending on the density of the fuel, the
limit in the Complex Model is currently 4.0% by
weight to reflect the maximum amount of oxygen
associated with E10. In most fuels, however, this
volume is equivalent to 3.5% by weight oxygen.

program. The NOX emission
performance requirements for RFG and
conventional gasoline have not been
required since January 1, 2007 when the
Tier2 gasoline average sulfur standard of
30 ppm took effect (see 40 CFR
80.101(c)(3)(i)). Finally, beginning
January 1, 2011, the air toxics emission
standards for gasoline will be deemed
met by compliance with the new
MSAT2 nationwide benzene standard
for gasoline, the volatility standard, and
sulfur standard (see 40 CFR 80.41(e)(2)
and (3)). The result is that beginning
January 1, 2011, only the VOC equation
in the Complex Model will continue to
be binding and only for RFG. For
conventional gasoline, there are no VOC
performance standards; only RVP limits.
Thus, compliance with the antidumping regulations does not require
use of the Complex Model to evaluate
VOC emissions.
The one exception to this is small
refiners that take advantage of the
option for delayed compliance with the
MSAT2 benzene standard until January
1, 2015. They would still need the
Complex Model for air toxics emission
performance compliance during this
interim period. However, since no small
refiners are currently producing RFG, it
would only be for CG. For CG, since
refiners typically certify CG as E0, with
oxygenate blended downstream, they
should be unaffected by the increase in
ethanol content from E10 to E15.
Therefore, it appears that the only
equation that needs to be modified in
the Complex Model to allow refiners
and importers to certify gasoline
containing E15 after January 1, 2011 is
the VOC equation.
Because emissions performance at
issue is specified in the Act as the
emissions performance of 1990 vehicle
technology, we are not able to use
current emission test data on motor
vehicles using E15 gasoline as a basis
for evaluating appropriate changes to
the VOC equation. The test results from
today’s vehicle fleet would not
represent the 1990 vehicle technology
required to calculate the emission
baseline. Instead, we relied on a study
conducted in 1994 by Guerrieri, et al.,
that examined the exhaust emissions
from 1990 vehicles using gasoline with
ethanol levels varying from 0 to 40
volume percent.45 Figure V.B–1 shows
data reported by Guerrieri et al.46 The

effect between E10 and E15, the linear
regression results presented in the study
(also shown in Figure V.B–1) indicate a
decreasing trend in hydrocarbon
emissions with increased ethanol in
gasoline. Based on the study findings,
we are reasonably confident that the
average VOC emissions for ethanol
blends greater than E10 up to and
including E15 will be no worse than for
E10, for 1990 technology motor
vehicles. This outcome is consistent
with our engineering judgment. As
discussed in Section VI.C the general
trend across vehicles of all ages is that
the addition of ethanol to gasoline tends
to lower VOC emissions due to its
enleanment effect during open loop
operation.
Because the data available on 1990
vehicles is limited, we are not proposing
to change the Complex Model to
indicate decreasing VOC emissions with
increased ethanol content between E10
and E15. Instead, we are proposing to
modify the application of the Complex
Model equations to treat VOC exhaust
emissions at ethanol levels greater than
E10 and up to E15 the same as for E10.
We are therefore proposing in today’s
rule to modify the Complex Model to
allow up oxygen levels up to 5.8% by
weight to be input to the model but that
the VOC emissions effects would be
modeled the same as if it contained
4.0% by weight oxygen.47 This will
provide flexibility for the Complex
Model to be used over a broader range
of ethanol content. We request comment
on whether the data and rationale
discussed above are an appropriate basis
for the proposed adjustment to the
Complex Model to account for E15.

Light-duty motor vehicles (i.e.,
passenger cars and light-duty trucks)
have evolved significantly over time,
mainly in response to increasingly
tighter emission standards, but also to
improve fuel economy, vehicle
driveability, and vehicle durability. The
primary advancements in emissions
control have been in the control of the
air-to-fuel (A/F) ratio matched with
advancements in catalyst formulations
and designs with each new generation
of motor vehicles. Today’s motor
vehicles are far more sophisticated and
up to 99% less polluting than they were
in the 1970s while also more tolerant of
variables like fuel composition (i.e.,
RVP, oxygen content). However,

vehicles have not benefitted from these

mitigation measures?
In previous sections we proposed to
prohibit the use of E15 in MY2000 and
older motor vehicles, heavy-duty
gasoline engines and vehicles,
motorcycles, and all nonroad products
(which includes marine applications).
This section provides the technical
rationale supporting this decision. As
discussed below, it appears that the
unique physical and chemical
properties of ethanol may impact these
products when they are using gasolineethanol blends, particularly as many of
these products were not designed to
operate on such fuels. The potential
impacts could be the impairment of the

advancements in technology and could
experience combustion and material
compatibility problems leading to
increased emissions if operated on E15.
While motorcycles (highway and offhighway), heavy-duty gasoline engines
and vehicles, and nonroad products
have also evolved over time, since they
have not been regulated as long, and
have much more diverse applications,
they do not reflect the same level of
advanced technology across the board as
do today’s light-duty motor vehicles.
Consequently, their engines and
emission control systems may also be
impacted in ways that affect emission
performance if operated on E15.
On the other hand, the Agency
believes that newer light-duty motor
vehicles (vehicles designed to meet Tier
2 emissions standards) were designed
with significantly more robust emission
controls and fuel system components to
regularly use gasoline-ethanol blends.
For MY2001–2006 light-duty motor
vehicles, EPA does not have enough
data on which to base a decision at this
point in time. DOE testing of MY2001–
2006 light-duty motor vehicles is
ongoing and will factor into the
Agency’s decisions for the final rule.
The sections that follow discuss in
more detail the history of ethanol use in
the U.S., the chemical and physical
differences between ethanol and
gasoline, and how these differences,
especially combustion enleanment and
material compatibility, could impact
exhaust and evaporative components
and emissions. Specifically, we discuss
the ability of the following groups of
vehicles and engines to handle E15: (1)
MY2000 and older light-duty motor
vehicles; (2) heavy-duty gasoline
engines and vehicles; (3) motorcycles;

A. History of Ethanol Use in the U.S.
Any assessment of the impacts of E15
use in vehicles, engines, and equipment
must begin with an understanding of the
degree to which they were designed for
the use of low level gasoline-ethanol
blends. E10 is currently blended in
significant quantities in most gasoline
distributed and sold in most States, but
this was not always the case. Most auto
manufacturers today support the use of
E10 in their vehicles and engines since
their designs have evolved over time in
response to the growing use of E10
across the country. However, the total
fleet is made up of old and new
vehicles, engines, and equipment with
varying technologies and therefore
varying compatibility with gasolineethanol blends.
Ethanol and ethanol-gasoline blends
have a long history as automotive fuels
in the United States. Inexpensive crude
oil prices kept ethanol from making a
significant presence in the
transportation sector until the end of the
20th century when tax subsidies and
environmental programs helped to spur
growth. On November 9, 1978, the U.S.
passed the Energy Tax Act which
defined ‘‘gasohol’’ as a blend of gasoline
with 10% alcohol by volume (excluding
alcohol made from petroleum, natural

excise tax exemption to encourage its
use.48 While the ethanol tax subsidy has

conventional ethanol continues to

gallon credit.

ethanol expansion in the United States.
First, in the late 1980s and early 1990s,
ethanol was used as a gasoline
oxygenate (along with MTBE) to help
reduce carbon monoxide (CO) emissions
in various CO nonattainment areas.
Then, ethanol was used as part of the
requirements for reformulated gasoline
in the worst ozone nonattainment areas
beginning in the mid 1990s.
Tax subsidies and environmental
programs resulted in the growth of the
fuel ethanol market such that by the late
1990s, E10 represented slightly more
than 10% of gasoline nationwide. By
1999, 35 States were blending ethanol
into at least a portion of their gasoline.49
However, its use remained concentrated
in the Midwest, e.g., Illinois, Ohio, and
Minnesota. Ethanol did not begin
expanding significantly beyond the
Midwest until the early 2000s when
States started banning the use of Methyl
Tertiary-butyl Ether (MTBE) due to
groundwater concerns. Ethanol quickly
became the primary oxygenate in the
gasoline market. With the removal of the
RFG oxygen mandate by the Energy
Policy Act of 2005 (EPAct), MTBE was
removed from gasoline almost entirely
by 2006. Ethanol replaced MTBE,
broadening the fuel’s use into
California, the East Coast, and other
RFG areas. From 2000 to 2006, the share
of gasoline containing 10% ethanol by
volume (‘‘E10 market share’’) more than
doubled as shown in Figure VI.A.-1.
According to fuel survey and
certification data, ethanol is the only
oxygenate currently used in any
significant quantity today.

EISA volumes.50 While there are a
number of renewable fuels that can be
used to meet the RFS2 requirements,
EPA projects a large percentage will
come from ethanol. According to EIA,
ethanol comprised 9.4% of total U.S.
motor gasoline sales during the first half
of 2010.51 In other words, over 90% of
motor gasoline sold today is E10.
As E10’s market share has increased
over the last few years, its prevalence
has also expanded nationwide. A map
showing today’s estimated E10
penetration by State is provided in
Figure VI.A–2. This State-level
information, provided by HART Energy
Consulting, does not reflect California’s
recent shift from 5.7 to 10 vol% ethanol.
While vehicles, engines, and equipment
in the Midwest have been experiencing
E10 use for a number of years, this is not
the case in most of the country. Even in
much of the Midwest, E10 has become
the dominant fuel only recently. It took
many years for States to reach 25% E10
saturation and even longer for States to
reach 50% E10 saturation. As shown in
Figure VI.A–3, 23 States (including the
District of Columbia) just recently
reached 50% saturation between 2008
and 2009.52 Alaska is the only State
without significant ethanol blending.
According to HART, only 10% of
Alaska’s gasoline is currently comprised
of E10.

Since 2006, E10’s market share has
continued to rise. The increase can be
attributed primarily to rising crude oil
prices which led to very favorable
ethanol blending economics over most
of the past 4–5 years, but also to the
market certainty provided by the

B. Chemical and Physical Differences
Between Ethanol and Gasoline
Understanding the chemical and
physical differences between gasoline
and ethanol is helpful in determining
how increased ethanol concentrations in
gasoline may impact vehicle and engine
technologies and whether emission
differences may occur. Throughout most
of the 20th century, engines and
vehicles were designed to run on
gasoline. Engines can and have been
designed for the use of ethanol, and in
the case of FFVs, have been designed to
operate effectively on both.53 Over the
last couple of decades, manufacturers
have also taken varying steps to
redesign their gasoline engines to be
more compatible with blends of gasoline
and ethanol up to 10 vol%.
Gasoline is a complex mixture of
several hundred hydrocarbon molecules
(organic compounds containing carbon
and hydrogen) ranging in carbon
number from four to twelve that are
produced from various refinery streams.
In contrast, fuel ethanol contains only
one kind of molecule with two carbon
atoms. Alcohols such as ethanol are
derived from hydrocarbons by replacing
the hydrogen atoms in their parent
hydrocarbon (ethane is the parent of
ethanol) with one or more hydroxyl
groups containing oxygen and
hydrogen.
Gasoline quality specifications are
provided by ASTM D4814,54 while
ethanol quality specifications for
blending in gasoline are provided by
ASTM D4806.55 Several properties of
ethanol, as compared to typical gasoline
and toluene, are listed below in Table
VI.B–1. Since toluene is a common
hydrocarbon used as an octane enhancer
in gasoline, it is included below for
comparison purposes.56 Ethanol has
been used successfully in gasoline for
several decades as a volumetric fuel
extender due to its beneficial Research

Because gasoline is composed of
different molecules of different lengths,
it has a boiling range as well as a
distillation curve. On the other hand,
because ethanol is composed of a single
type of molecule, it has a single boiling
point and lacks the characteristic
distillation curve of gasoline. Functional
groups such as ethanol’s hydroxyl group
generally determine how a molecule
will behave.
The question with the use of E15 is
whether or not the vehicles, engines,
equipment, and products that are
designed for the properties of gasoline
and/or E10 are also designed for the
properties of E15. Some property
differences between E10 and E15 may
be dealt with in fuel blending such that
the base gasoline can be adjusted in
advance to accommodate the ethanol.
This adjustment will ensure that the
resulting blend meets a target
specification for properties such as
volatility and octane rating. On the
other hand, some property differences
between E10 and E15 are inherent to the
ethanol fraction and cannot be
accounted for by blending. For example,
the impact of E15 versus E10 on engine
combustion is a potential concern. How
a vehicle or engine adapts to combust
fuels with different ethanol
concentrations depends on the vehicle
hardware and software control
strategies. Vehicles and engines
operating on E15 may have hotter
exhaust temperatures than the same
vehicles and engines running on E10. In
addition, material compatibility is time,
temperature, and concentration
dependent. Some material effects with
E15 are possible that may not have been
experienced with E10 in the past.
The following sections describe in
greater detail the chemical and physical
differences of gasoline and ethanol,
particularly focusing on the effects of
these differences when ethanol is
blended with gasoline. This discussion
lays the foundation for vehicle and
engine specific discussion in sections
VI.C.–VI.I.
53 In the U.S., the most common FFVs are also
known as ‘‘E85’’ vehicles. They are designed to run
on gasoline or a blend of up to 85 vol% ethanol
(E85) and are equipped with modified components
designed specifically to be compatible with
ethanol’s chemical properties.

1. Impact on the A/F Ratio—
Combustion Enleanment
When gasoline is combusted in an
engine, the stoichiometric A/F ratio (i.e.,
the ideal ratio for complete combustion
of the fuel and air into carbon dioxide
and water vapor) is approximately 14.7
times the mass of air to fuel (14.7:1). For
gasoline, any mixture less than 14.7:1 is
E:\FR\FM\04NOP2.SGM
04NOP2
68068
Federal Register / Vol. 75, No. 213 / Thursday, November 4, 2010 / Proposed Rules
considered to be a rich mixture (excess
fuel), and any mixture more than 14.7:1
is a lean mixture (excess air/oxygen)
given ideal test fuel and complete
combustion. The addition of oxygenates
such as ethanol (with its hydroxyl
group) to gasoline alters the
stoichiometric A/F ratio and therefore
affects combustion. Engines/vehicles
equipped with feedback controls can
adjust the A/F ratio to stoichiometric
conditions—around 14.0:1 for E10 and
13.8:1 for E15 (the ratio is lower as
ethanol contains oxygen so less air is
needed). However, for gasoline engines
that do not have the ability to react to
the desired stoichiometric A/F ratio for
a different fuel (e.g., gasoline-ethanol
blends), combustion is enleaned. E10
would result in approximately 4%
enleanment when compared with
gasoline, E15 would result in
approximately 6% enleanment. This
means E10 and E15 have 4% and 6%
more oxygen, respectively, than the
stoichiometric A/F ratio.
Fuel metering components are sized
to deliver an A/F mixture that optimizes
emission performance, power output,
fuel economy, and durability. If an
engine is allowed to operate at a mixture
that is leaner than it is designed for (too
much oxygen for a given amount of
fuel), it may run at a somewhat higher
combustion temperature. This in turn
can lead to changes in exhaust
temperatures which may affect catalyst
durability, and, especially in the case of
nonroad products, engine durability,
causing an increase in emissions. In
addition, combustion instability from
lean mixtures, which can cause misfire,
can then lead to accelerated catalyst
performance degradation or damage.
2. Polarity and Affinity for Water
Water is one of the most polar
molecules (an uneven distribution of
charge with the hydrogen atoms being
positively charged and the oxygen atom
negatively charged) while ethanol is
only slightly polar and a hydrophilic
(meaning water loving) molecule
because of its hydroxyl group. Ethanol
dissolves in water when the two are
mixed together. Unlike ethanol, gasoline
is considered to be a non-polar and
hydrophobic hydrocarbon molecule
which means that it does not attract
water in the same way as ethanol does.
As a result, gasoline and water are only
very slightly soluble. If enough water is
added to straight gasoline, two layers
will form, known as phase separation: a
water layer and a gasoline layer.
Ethanol is soluble in gasoline though
to a lesser extent than it is in water. If
a gasoline-ethanol blend is saturated
with water, a reduction in ambient
temperature may cause the ethanol and
gasoline to separate into two layers.
However, the presence of ethanol in
gasoline will allow more water to be
absorbed by the gasoline-ethanol blend
before phase separation occurs. Some
level of water carried through the fuel
distribution system is generally
acceptable and likely unavoidable given
fuel exposure to moisture and humidity
in normal dispensing and storage, either
at the fuel station or on-board. However,
excessive water in the fuel can lead to
phase separation that can in turn cause
stalling or permanent damage to most
internal combustion engines.
3. Material Compatibility
The hydroxyl group of ethanol also
reacts with natural rubber materials.
Certain elastomers exposed to alcohols
may swell or soften and lose strength.62
Some plastics and fiberglass can become
brittle leading to cracks and leaks.63
Table VI.B.2.–1 shows the effects of
gasoline and ethanol on some of the
many elastomers that have been
developed.64 As noted from this table,
polyfluorocarbons have been shown to
be compatible with ethanol and ethanol
blends. As discussed below in VI.C.2.,
the physical interaction of ethanol with
certain elastomers also leads to
increased permeation of ethanol and
hydrocarbons through the walls of
components made from such materials.

could promote galvanic corrosion and
galvanic-couple effects between
electrochemically dissimilar alloys in
the fuel system.65, 66 The National
Ethanol Vehicle Coalition and the

demonstrated that aluminum is
sensitive to corrosion from ethanol. In
addition, water in gasoline-ethanol

materials (such as brass, cast iron,
copper, and various types of steel) as the

water/ethanol layer becomes acidic if
phase separation occurs.67 The presence
of water in the fuel distribution system
also provides a suitable habitat for the
growth of microbes which excrete acids
that in turn are also detrimental to
metallic fuel storage systems.68
Contaminants in water may also impact
additives used in finished fuel that are
designed to maintain the integrity of the
finished fuel.69, 70, 71 Because of these
corrosion concerns, actions are usually
taken to accommodate ethanol in
ethanol production, storage, and
distribution systems, as well as in
vehicles and engines. Such actions
include the careful selection of
materials and/or the use of appropriate
ethanol compatible coatings on
susceptible metal parts that come into
contact with the ethanol fuel, as well as
the use of corrosion and biocide
additives.

5. Solvency
Ethanol can also act as a solvent for
various materials. As such, ethanol has
historically been known to remove or
dissolve components built up in the fuel
storage, handling and delivery systems
(e.g. fuel tank, fuel lines, injectors, etc.).
Once these components are loosened or
partially dissolved, they are transported
through the fuel system, and if
excessive, may cause fuel filter, injector
plugging or other component problems,
all of which can lead to poor operability
and degraded emission performance.
Gasoline-ethanol blends may also pick
up contaminants from storage tanks and
delivery trucks. The amount of build-up
is related to a combination of fuel
composition properties and fuel usage
patterns (i.e., regular fuel usage versus
infrequent, etc.). Non-automotive
equipment may experience fuel filter
plugging related more to extended
storage periods where gasoline can
deteriorate and lead to more deposits
requiring a plugged fuel filter
replacement.

6. Volatility
Fuel volatility is a measure of a fuel’s
vapor pressure or its tendency to
vaporize. When ethanol is blended into
gasoline, the hydrogen bonding between
the ethanol molecules is weakened
significantly and the alcohol
‘‘depolarizes.’’ This results in higher
Reid Vapor Pressures (RVP) for gasoline
containing ethanol. Ethanol’s effects on
RVP have been well
documented,72, 73, 74 where low level
ethanol blends, in general, will increase
gasoline RVP by up to one pound per
square inch with the maximum effect
occurring at approximately 3 vol%
ethanol concentration. The RVP of the
base fuel will also influence just how
much increase will occur by the
addition of ethanol.75 Increases in RVP
result in increased vapor generation and
increased evaporative emissions.
Additionally, while ethanol at certain
levels may raise the general volatility of
the gasoline-ethanol blend, because of
ethanol’s single boiling point and high
latent heat of vaporization, the ethanol
fraction may cause combustion
difficulties and increased emissions
during the start of some spark-ignition
engines when the engines are cold,
particularly at colder start temperatures.
Further, once the engine is hot, the
single boiling point can also cause
difficulty in operating and starting a hot
engine as observed in older motor
vehicles when ethanol first became
available. The ethanol would reach its
boiling point in the fuel system and
result in what is known as ‘‘vapor lock.’’
C. Model Year 2000 and Older LightDuty Motor Vehicles
Ethanol impacts motor vehicles in
three primary ways. First, as discussed
in Section VI.B.1 above, ethanol enleans
the A/F ratio which leads to increased
exhaust gas temperatures and therefore
potentially incremental deterioration of
emission control hardware and
performance over time. Second, over
time, enleanment caused by ethanol can
ultimately lead to catalyst failure. Third,
ethanol can cause material compatibility

issues which may lead to other
component failure. Ultimately, all of
these impacts may lead to exhaust and/
or evaporative emission increases.
1. Enleanment
MY2000 and older light-duty motor
vehicles have much less sophisticated
emissions control systems compared to
today’s motor vehicles and, as described
below, may experience conditions that
lead to both immediate emission
increases and increases over time if
operated on E15. Vehicles produced
prior to the mid-1980s were equipped
primarily with carbureted engines. The
A/F ratio of the carburetor is preset at
the factory based on the expected
operating conditions of the engine such
as ambient temperature, atmospheric
pressure, speed, and load. As a result,
carburetors have ‘‘open loop’’ fuel
control which means that the air and
fuel are provided at a specified,
predetermined ratio that is not
automatically adjusted during motor
vehicle operation. As fuel composition
can vary, an engine with a carburetor
and open loop fuel control would never
know whether it achieved the desired
A/F ratio. Since the motor vehicles at
this time operated ‘‘open loop’’ all of the
time with no ability to react for changes
in the A/F ratio, the addition of ethanol
to the fuel tended to make the A/F ratio
leaner—closer to stoichiometry, which
had the immediate effect of reducing HC
and CO emissions, but increasing NOX
emissions. However, some of these older
open loop systems already operate at the
lean edge of combustion on current
commercial fuels so an increase in
ethanol may cause them to begin to
misfire resulting in HC and CO
increases.
As a result of the Clean Air Act, EPA
established standards and measurement
procedures for exhaust, evaporative, and
refueling emissions of criteria
pollutants. From 1975 into the 1980s,
motor vehicles became equipped with
catalytic converters, first with catalysts
capable of oxidizing HC and CO, and
then, in response to EPA’s ‘‘Tier 0’’
standards, with three-way catalysts that
also reduced NOX. Motor vehicles
produced in the 1980s and even more so
in the 1990s as a result of more stringent
California and Federal (e.g., ‘‘Tier 1’’)
standards evolved to incorporate more
sophisticated and durable emission
control systems. These systems
generally included an onboard
computer, oxygen sensor, and electronic
fuel injection with more precise closedloop fuel compensation and therefore

with the use of closed loop systems
through the late 1990s, the emission
control system and controls remained
fairly simple with a limited range of
authority and were primarily designed
to adjust for component variability (i.e.,
fuel pressure, injectors, etc.) and not for
changes in the fuel composition. During
this period, ethanol was only available
in very limited areas of the US so the
manufacturers’ designs of the emission
controls and the durability of emission
control hardware generally did not
account for the increased oxygen
content of ethanol. As a result, this
generation of vehicles certified to Tier 0
and early Tier 1 emission standards
operated leaner on ethanol, causing
immediate emission impacts (lower HC
and CO emissions, higher NOX
emissions) and may have also
deteriorated at different rates when
exposed to ethanol. These designs
continued to evolve during the early
period of the Tier 1 emission standards
as manufacturers and component
suppliers gained experience with
vehicles in-use. However, the largest
improvements to emission controls and
hardware durability came after 2000
with the introduction of several new
emission standards and durability
requirements forcing manufacturers to
better account for the implications of inuse fuels on the evaporative and exhaust
emission control systems.
While most motor vehicles are
operating today on E10, motor vehicles
operated on E15 will likely run even
leaner than those operated on E10
depending on the motor vehicle
technology and operating conditions.
Enleaned combustion leads to an
increase in the temperature of the
exhaust gases. This increase in exhaust
gas temperatures has the potential to
raise the temperatures of various
exhaust system components (e.g.,
exhaust valves, exhaust manifolds,
catalysts, and oxygen sensors) beyond
their design limits. However, based on
past experience, the most sensitive
component is likely the catalyst,
particularly in older motor vehicles
with early catalyst technology. Catalyst
durability is highly dependent on
temperature, time, and fuel gas
composition. Catalyst temperatures
must be controlled and catalyst
deterioration minimized during all
motor vehicle operation modes for the
catalyst to maintain high conversion
efficiency over the motor vehicle’s life.
This is particularly important during
high load operation of a motor vehicle
where high exhaust gas temperatures are
encountered and the risk for catalyst
deterioration is highest. Catalysts that
VerDate Mar<15>2010
18:04 Nov 03, 2010
Jkt 223001
exceed temperature thresholds will
deteriorate at rates higher than
expected, compromising the motor
vehicle’s ability to meet the required
emission standards over its full useful
life. Extended catalyst exposure to
higher exhaust temperatures can
accelerate catalyst thermal deactivation
mechanisms (e.g., sintering of active
precious metal sites, sintering of oxygen
storage materials, and migration of
active materials into inert support
materials). While this damage can occur
at a highly accelerated rate with a
sudden change in temperature (e.g.,
with a misfire allowing raw fuel to reach
the catalyst), it is more likely to occur
over time from elevated exhaust
temperatures as may be experienced
with frequent or even occasional
exposure to E15. This deterioration may
adversely affect a motor vehicle’s ability
to control emissions, particularly after
significant mileage accumulation.
Some motor vehicles may be able to
manage catalyst temperatures by
compensating for the oxygen in the fuel
under all operating conditions,
including high loads. This is achieved
by using a closed-loop fuel system that
measures the A/F ratio and makes the
appropriate corrections to maintain the
A/F ratio in the very tight ban of
operation around stoichiometry
necessary for optimum catalyst
performance and reductions in HC, CO,
and NOX emissions. The part of the
closed-loop fuel system that is
responsible for the correction to the
A/F ratio is referred to as ‘‘fuel trim.’’
The fuel trim adds or removes fuel to
the engine to maintain the required
A/F ratio. If the measured A/F ratio has
insufficient oxygen, or is ‘‘rich’’
compared to what the engine needs, the
fuel trim will instruct the fuel injectors
to inject less fuel, making the A/F ratio
‘‘leaner.’’ The opposite is true if the
measured A/F ratio has too much
oxygen and needs to inject more fuel for
a ‘‘richer’’ A/F ratio. The fuel trim is
generally comprised of two major parts,
short term fuel trim and long term or
adaptive learned fuel trim. Learned fuel
trim, also known as adaptive fuel trim,
can also be applied to open loop
operation such as high load or wide
open throttle to alleviate the catalyst
temperature increases caused by
operating on E15 fuel. However, while
this strategy was more common in later
model years closer to MY2000, it was
not consistently employed by all
manufacturers. Some manufacturer
models may have less range of authority
than others and some may require
longer periods of time to adapt. Hence,
control algorithms and calibrations used

by some manufacturers may be more
effective than others.
The fuel trim has a limited range of
adjustment in which it can continue to
update the A/F ratio and maintain the
fuel system at or near stoichiometry. For
MY2000 and older light-duty motor
vehicles, the fuel trim range is generally
more limited than the range for newer
light-duty motor vehicles, and MY2000
and older motor vehicles may use their
full range of fuel trim adjustment to
account for normal component
deterioration. Injectors, sensors and
changes to fuel pressure may shift with
time and aging to use all of the fuel
trim’s range of adjustment. The
additional oxygenate in E15 may
actually shift the A/F ratio more than
the earlier introduction of E10 if the
engine’s A/F ratio feedback cannot
compensate because it has reached its
adjustment limit. In short, MY2000 and
older motor vehicles are at risk of
having insufficient thermal margins to
accommodate ethanol blends up to E15
due to the limits of their fuel trim range.
Test data to confirm or refute
concerns over the use of E15 in older
vehicles is very limited in scope and
content. The available data do not prove
or disprove the concerns, although there
are several studies that support the
potential for long term durability issues
consistent with engineering theory.
Three studies—the CRC Screening
Study, DOE Pilot Study, and the Orbital
Study—discussed in section IV.A.
highlight in particular the concern with
MY2000 and older motor vehicles. The
CRC Screening Study (E–87–1) was a
test program developed to look at the
effects of mid-level ethanol blends on
U.S. vehicles.76 This screening study
was the first phase of a two-phase study
evaluating the effects of mid-level
ethanol blends on emission control
systems. The purpose of this first phase
of the study was to identify vehicles
which used learned fuel trims to correct
open loop air-fuel rations. Under the
test program a fleet of 25 test vehicles
was identified and acquired with six of
those vehicles being MY2000 and older.
The study collected vehicle speed,
oxygen sensor air-fuel-ratio, and catalyst
temperature data for four fuels (E0, E10,
E15, and E20). The results of the three
ethanol blended fuels compared to E0
showed that four of the six MY2000 and
older vehicles tested failed to apply
long-term fuel trim to open loop
operation in order to compensate for
increasing ethanol levels. And that these

same four vehicles exhibited increased
catalyst temperatures when operated on
E20 as compared to E0. While the
subsequent DOE Catalyst Study
concluded that this learned fuel trim
was not important for MY2007 and
newer motor vehicles because they are
durable (and therefore can handle E15)
as discussed in section IV.A, there was
no such follow on program for MY2000
and older motor vehicles so the
durability of these vehicles on E15 is
unknown.
Another study suggests that many
MY2000 and older motor vehicles may
also have emission exceedances if
operated on E15. In 2003, the Orbital
Engine Company issued a report on the
findings of vehicle testing it completed
to assess the impact of E20 on the
Australian passenger vehicle fleet.
While the Australian vehicles in this
study were not representative of U.S.
vehicles of the same model years, they
are similar to MY2000 and older U.S.
motor vehicles with respect to
technology and emission standards. The
testing program covered vehicle
performance and operability testing,
vehicle durability testing, and
component material compatibility
testing, on nine different vehicle makes
or models, five vehicles from MY2001
and four vehicles from MY1985 to
MY1993. Testing results showed
increases in exhaust gas temperature in
five of the nine vehicles tested with
three showing increases in catalyst
temperature. Enleanment was found to
occur in six of the nine vehicles tested,
with three having closed loop control—
the old vehicles without closed loop
control all displayed enleanment. In
general, the increase in exhaust gas
temperature was found to follow those
vehicles with enleanment. Furthermore,
one vehicle in the study experienced
catalyst degradation sufficient to make
the tested vehicle no longer meet its
applicable Australian emission
standards.
EPA recently received a report by
Ricardo 77 commissioned by the
Renewable Fuels Association
specifically discussing the potential
impacts of E15 on MY1994–2000 lightduty motor vehicles. However, as
discussed in the decision document, it
sheds little new light on the potential
emission impacts of E15 on MY2000
and older motor vehicles. While arguing
that many MY1994–2000 motor vehicles
may be designed to be compatible with
E15, it did so only for ‘‘properly
engineered’’ vehicles. Furthermore, it
acknowledged potential emission
increases in-use, but in the context of
the waiver decision highlighted that
they were likely within manufacturer
compliance margins. Finally, it drew
many of its conclusions only relative to
E10, not to E0.
Hence, based on the limited data
available and our engineering judgment,
we conclude that MY2000 and older
motor vehicles have the potential to
experience conditions when operated
on E15 which may ultimately lead to an
increase in emissions.

2. Material Compatibility
Data and information exist in the
literature regarding ethanol’s impacts on
motor vehicle material compatibility.
Engine, fuel system, and emission
control materials (metals, plastics, and
elastomers) must maintain their
integrity for motor vehicles to meet their
exhaust and evaporative emissions
standards. Material incompatibility can
result from the chemical reaction or
physical interaction between a fuel and
material with which it comes into
contact. This can lead to emissions
compliance problems not only
immediately upon using the new fuel or
fuel additive, but especially over time.
In most cases one would expect any
materials incompatibility to show up in
the emissions tests, but there may be
impacts that do not show up due to the
way the testing is performed or because
the tests simply do not capture the
effect. As a result, along with emissions
testing, materials compatibility is a key
factor in assessing the emissions
durability of a fuel or fuel additive.
Based on our engineering assessment,
it appears that manufacturers took
varying steps at different points in time
to transition the materials in their motor
vehicle designs to be E10 compatible.
Many in the mid-to-late 1980s took
steps for E10 compatibility at least for
the more immediate effects of ethanol
(e.g., the dissolving of certain
elastomers). Large parts suppliers began
testing materials on gasoline-ethanol
blends in the mid-to-late 1980s and
early 1990s, but practices varied with
manufacturer. At the same time, certain
areas have now had E10 for a number
of years and therefore motor vehicles in
these areas have experienced a much
higher frequency of ethanol exposure.
This has led many to argue that ethanol
is compatible for all motor vehicles in
the in-use fleet and therefore E15 should
PO 00000
Frm 00029
Fmt 4701
Sfmt 4702
68071
be too. However, since the effects would
be long term, it is difficult to assess
whether these motor vehicles
experienced any higher rates of
deterioration or component failure on
E10. Furthermore, material
compatibility with ethanol is time,
condition (e.g., temperature, pressure),
and concentration dependent, such that
problems may occur with E15 that did
not show up with E10.
Moving from E10 to E15 reflects a
50% increase in the volume of ethanol
present in gasoline. Therefore, since the
impacts of ethanol on materials are a
function of concentration, E15 has the
potential to have more significant
impacts than E10 if used in motor
vehicles not equipped for it. For
MY2000 and older motor vehicles, E15
use may result in degradation of
metallic and non-metallic components
in the fuel and evaporative emissions
control systems that can lead to highly
elevated hydrocarbon emissions from
both vapor and liquid leaks. Potential
problems such as fuel pump corrosion
or fuel hose swelling would likely be
worse with E15 than historically with
E10, especially if motor vehicles will be
operating exclusively on it. Since
ethanol historically comprised a much
smaller portion of the fuel supply (see
section VI.A.), in-use experience with
E10 was often discontinuous or
temporary, while material effects are
time and exposure dependent. Thus,
problems may surface with E15 that
have not surfaced historically in-use.
Additionally, leak detection diagnostics
did not appear until MY1996 and
enhanced evaporative test procedures
were not fully implemented until the
late 1990s.
In addition to potential vapor or
liquid leaks, ethanol is also known to
facilitate permeation through the
materials in the fuel system. Studies
have shown this to be a significant
source of increased emissions with
gasoline-ethanol blends, especially on
older motor vehicles. Following
additional testing requirements as part
of the Tier 2 motor vehicle emission
standards beginning in 2004, materials
in newer motor vehicles have been able
to mitigate the permeation effects of
ethanol in the fuel, as discussed in the
waiver decision document. However, as
shown in the Figure VI.C.2–1 below,
permeation emissions from older model
year vehicles may be very high with
ethanol blends.78

As part of its waiver application,
Growth Energy submitted a series of
studies completed by the State of
Minnesota and the Renewable Fuels
Association (RFA) that investigated
materials compatibility of motor vehicle
engines and engine components using
three test fuels: E0, E10, and E20
(‘‘Minnesota Compatibility Study’’).79

Results from the Minnesota study
were mixed depending on if the

E20 and E10 or E20 and E0. Some
materials were compatible with the
ethanol blends while some displayed
larger property changes with the ethanol
blends. Because of the immense variety

of materials available and the overlap in
use of the different materials over time,
the study could not test all materials in
the fleet, nor did it directly assign the
materials tested to a vehicle generation
or model year. Instead, the study
generalized that because ethanol was
available in some parts of the U.S., these
materials were likely E10 compatible.
However, these materials were used
prior to the widespread use of ethanol
and therefore conceivably prior to many
manufacturer’s requirement for
prolonged exposure to ethanol and
specifically not for gasoline-ethanol
blends above 10%. It is difficult to
quantify the overall impact of changes
in any material due to ethanol at E15 or
E20 levels and what those changes
would mean to the older motor vehicle
fleet, only that some portion of the fleet
may experience changes that could
result in accelerated component failures
beyond what would be expected on E0
or E10. In addition, it is important to
note that the Minnesota Compatibility
Study assessed component parts using
laboratory bench tests rather than
durability studies of whole motor
vehicle fuel systems simulating ‘‘real
world’’ motor vehicle use.

In addition to providing comments on
the Minnesota Compatibility Study as
discussed in the waiver decision
document, the Alliance commented that
engines need to be hardened for
resistance to ethanol. Use of gasolineethanol blends in unhardened engines
can result in bore, ring, piston and valve
seat wear. Deterioration of these
components can lead to compression
and power loss, misfire and catalyst
damage.
Based on our review of the literature
and industry comments on the E15
waiver request, we believe that MY2000
and older light-duty motor vehicles
have the potential for increased material
degradation with E15 use. In addition,
some MY2000 and older light-duty
motor vehicles may have been designed
for only limited exposure to E10 while
the oldest vehicles on the road pre-date
ethanol blends in the marketplace all
together. This potential for material
degradation may make the emissions
control and fuel systems more
susceptible to corrosion and chemical
reactions from E15 when compared to
the E0 certification fuels for these motor
vehicles and may ultimately increase
vehicle emissions, especially for
MY2000 and older motor vehicles.

3. Motor Vehicle Population and
Anticipated Emissions Impact
There is a long history of test
programs that have been carried out on
light-duty motor vehicles and trucks
that have quantified the immediate
emission impacts of blending ethanol
up to 10 vol% into gasoline. These test
programs, dating back to the earliest
days of gasoline-ethanol blends, have
found that the oxygen content of ethanol
enleans the A/F ratio in motor vehicles
during open-loop operation, causing a
decrease in HC and CO emissions, but
also results in a corresponding increase
in NOX emissions. These studies have
been used to develop emission models,
such as the EPA Predictive Models 86
incorporated into the Agency’s MOVES
model,87 that have been thoroughly peer
reviewed. The result is that for a typical
E10 blend of gasoline, exhaust NMHC
emissions have been found to decrease
by about 5%, and NOX emissions to
increase by about 6%, relative to E0.88
86 A detailed description of the development of
the EPA Predictive Models is available in a
Technical Support Document: ‘‘Analysis of
California’s Request for Waiver of the Reformulated
Gasoline Oxygen Content Requirement for
California Covered Areas’’, EPA420–R–01–016, June
2001.
87 The Agency’s MOVES model has undergone
extensive peer review and testing, and incorporates
the EPA Predictive Models.
88 These effects are based the EPA Predictive
Models and are generally consistent with

While the magnitude of impact may
vary by a few percent depending on the
motor vehicle technology and how other
fuel properties change when ethanol is
blended into gasoline, the relative
magnitude and direction of the impacts
remains consistent for typical fuels.89
The limited available data on E15
suggests that this trend continues, and
is slightly more pronounced due to the
higher ethanol content. However, these
emission impacts are not the focus of
this proposal as their magnitude tends
to be within vehicle compliance
margins (the difference between a
vehicle’s actual emission certification
level and the standard). Rather, for this
proposal, we have focused on long-term
durability issues associated with E15, as
discussed in more detail below. The
issue of immediate emission increases
for E15 is more properly addressed as
part of the anti-backsliding study and
rulemaking under section 211(v) of the
Act.
Sufficient data do not exist to predict
specific changes in emission rates for
the various motor vehicle technologies
due to long-term use of E15 blends.
However, with respect to exhaust
emissions, if a catalyst were to be
damaged to the point of having no
significant remaining functionality, we
could expect NOX emissions similar in
magnitude to those in untreated engineout exhaust (i.e., before treatment by the
catalyst). If, in this situation, the fuel
control system continued to operate in
closed-loop mode, NOX emission levels
in the range of 2–4 g/mi would be
expected, or approximately ten times
the typical emissions rate for a properly
operating 1990s-era motor vehicle and
about 60 times that of new cars today.90
Similarly, loss of catalyst function could
also cause significant HC emission
increases, where levels on the order of
conclusions of CRC E–74b report (e.g., Figure ES–
2). Fuels properties evaluated were based on market
averages and were as follows: E0 had aromatics
content of 29.5 vol%, a T50 of 215 °F, a T90 of 325
°F, and an RVP of 8.9 psi and E10 had aromatics
content of 24.9 vol%, a T50 of 202 °F, T90 of 325
°F, and an RVP of 8.9 psi. Other parameters not
mentioned here were assumed to be held constant
between the blends.
89 Results based on data mostly from vehicle
models that predated the Tier 2 emission standards,
so several recent test programs have been focused
on Tier 2 vehicles that will soon make up the
majority of the in-use fleet.

A vehicle not operating in closed-loop mode may
emit more or less NOX depending on combustion
behavior. During the 1990s, Federal emission
standards for NOX dropped from 1 g/mi to 0.4 g/
mi.

2 g/mi could be expected.91 This would
be equivalent to combined HC
emissions of 40 new cars today. While
this kind of complete failure would
likely be limited in nature, misfueled
motor vehicles may experience a
reduction in catalyst efficiency earlier
than intended, resulting in emissions
levels increased above current levels
and up to the uncontrolled engine-out
levels presented above.
Another area of concern related to
exhaust emissions is fuel pump
malfunction occurring due to material
incompatibility of higher ethanol
content with parts such as plastic pump
rotors, shaft seals or elastomeric tubing,
and increased corrosion of metallic or
electrical components. As described in
Section VI.B, ethanol increases the
electrical conductivity of fuel,
increasing the likelihood that galvanic
corrosion of metal parts would occur.
Before outright failure, malfunctioning
fuel pumps often provide inconsistent
fuel pressure for some period of time,
resulting in long crank (starting) times,
misfires, and other erratic engine
behavior. Should such conditions occur,
they may cause increases in exhaust
emissions and possible deterioration of
exhaust catalysts.
In addition to the potential for
exhaust emissions increases,
evaporative emissions are also expected
to increase, not only immediately due to
increased permeation (as discussed
above), but also due to long-term E15
use that may cause from increased
corrosion of metallic fuel system
components and accelerated
deterioration of elastomeric hoses and
seals. Corrosion may result in vapor or
liquid leaks, depending on where in the
fuel system the corrosion is located.
Many types of elastomers used in orings and fuel lines swell or crack when
exposed to ethanol, resulting in
increased permeation of vapor or liquid
leaks. Elastomeric seals on older motor
vehicles may already be brittle and
weakened from age. Exposure to E15
may produce accelerated failures of
these elastomeric components.
Though it is difficult to quantify the
impacts of these types of evaporative
component failures, a recent evaporative
emissions study produced some
relevant data. During the program, a
motor vehicle with a fuel system leak
due to an o-ring failure produced
between 23–26 times more gasoline
vapor during a pair of diurnal tests than

a properly-functioning new motor
vehicle meeting current standards.92
The study also placed very small
simulated leaks (essentially pin holes)
in gas caps of three motor vehicles,
representative of what could occur as a
result of tiny corrosion sites in the vapor
space of the fuel tank. Diurnal tests were
performed to compare the emissions
with and without the leaks. The
MY1996 motor vehicle produced 54
times more evaporative emissions with
the simulated leak, while the MY2001
and 2004 motor vehicles produced two
and three times more vapors,
respectively. The study authors point
out that the two newer motor vehicles
had tank vent systems designed to meet
onboard refueling vapor recovery
(ORVR) requirements, suggesting this
may mitigate the effect of vapor space
leaks.93
Thus, we may conclude that even
small vapor space leaks occurring in
older motor vehicles (before ORVR was
required) have the potential to result in
large increases in HC emissions.
For more discussion on potential
evaporative issues, refer to the Waiver
Decision document Section IV.A.3 that
was also released today.

projected population of motor
vehicles—passenger cars and light-duty
trucks in the fleet—by model year for

the total estimated 225 million cars and
trucks that operate on gasoline in the
fleet today,94 nearly 73 million or onethird are MY2000 and older light-duty
motor vehicles, and it is these motor
vehicles for which the effects of E15 are
uncertain but indicate the potential for
anywhere from small to significant
emission increases from the
deterioration of the emissions control
system over time. As discussed above, if
motor vehicles experience engine or
emission component failure, the
potential exists for very elevated
exhaust and/or evaporative system
emissions rates. If only a fraction of the
fleet were to experience problems with
E15, that would still be a large number
of motor vehicles with a potentially
significant impact on in-use emissions.

D. Heavy-Duty Gasoline Engines and
Vehicles
E. Motorcycles
Given its limited market, heavy-duty
gasoline engines and vehicles have not
been the focus of test programs and
efforts to assess the potential impacts of
E15 on such engines. From a historical
perspective, the introduction of heavyduty gasoline engine and vehicle
technology has lagged behind the
implementation of similar technology
for light-duty motor vehicles. Similarly,
emission standards for this sector have
lagged behind those of light-duty motor
vehicles, such that current heavy-duty
gasoline engine standards remain
comparable from a technology
standpoint to older light-duty motor
vehicle standards. Consequently, we
believe the discussion in Section VI.C.
for MY2000 and older motor vehicles
should also be applicable to the majority
of the in-use fleet of heavy-duty gasoline
engines and vehicles. Therefore, we are
proposing to prohibit the use of E15 in
heavy-duty gasoline engines and
vehicles. We seek comment on this
assessment.
Motorcycles come in many different
sizes, styles and applications. The
biggest distinction between motorcycle
types are that some are designed for
operation on-road and others are
designed for operation off-road. The
motorcycles designed for operation onroad are referred to as highway
motorcycles. Highway motorcycles can
range from small scooters equipped
with a 50 cubic centimeter (cc) single
cylinder two-stroke engine to a large
touring motorcycle equipped with a
multi-cylinder four-stroke engine with
an engine displacement exceeding 2,000
cc. Motorcycles designed for off-road
operation are referred to as off-highway
motorcycles and can differ significantly
from highway motorcycles in design
and appearance.
Motorcycles have been around for
well over 100 years. The fuel system
used to manage the A/F ratio for
motorcycles has been the carburetor. In
fact, the carburetor has been the fuel
control system of choice for highway
and off-highway motorcycles until the
last decade. Starting in the late 1990s,
92 Diurnal testing refers to a process for measuring
evaporative emissions where a vehicle is placed in
a sealed enclosure and the temperature varied over
multiple cycles to simulate ambient day and night
conditions in summertime. See Coordinating
Research Council Report No. E–77–2 for detailed
results (available at https://www.crcao.org).
93 Onboard refueling vapor recovery systems were
phased into production in light-duty motor vehicles
over MY1998–2000, and provide a relatively short,
large-diameter pathway for vapors to reach the
carbon canister where they are stored for
combustion during engine operation. See

some of the more expensive high
performance highway motorcycles
began to use electronic fuel injection
(EFI) to manage the A/F ratio. While EFI
is becoming more common today in
many highway motorcycles, there are
still many models that use carburetors.
Off-highway motorcycles have only
begun to use EFI in a very few
expensive competition models. The vast
majority of off-highway motorcycles
continue to use carburetors.
All internal combustion engines need
a system to cool the engine from the
excessive heat generated as part of the
combustion process. Without a cooling
system, the engine would quickly
overheat and fail. Motorcycles use two
types of engine cooling systems: liquidcooled and air-cooled. Liquid-cooled
systems are very similar to the systems
used by automobiles. A radiator stores
a liquid coolant that is distributed
throughout the engine which cools the
engine. The heated coolant is returned
to the radiator where it is cooled by air
from the moving motorcycle or from an
external fan. An air-cooled system is
similar to that used for most nonroad
engines and is less sophisticated than a
for detailed results (available at https://
www.crcao.org).
94 There are approximately 250 million cars and
trucks in the fleet today when diesels are included.

liquid-cooled system. An air-cooled
system uses a series of external ‘‘fins’’
located on the cylinders and cylinder
heads that help direct heat away from
the cylinder and cylinder head. Since
the engine in a motorcycle is exposed to
the atmosphere and not contained in an
engine compartment like an automobile,
the engine is exposed to passing air as
the machine is operated on the road or
trail. The passing air is channeled
through the fins and helps cool the
cylinder and cylinder head, which helps
cool the combustion chamber, reducing
the overall engine temperature. Aircooling is not nearly as effective at
controlling engine temperature as liquid
cooling. One of the strategies to help
with engine cooling for engines that rely
on air-cooling is to operate the engine at
an A/F ratio that is rich of
stoichiometry. The additional fuel helps
reduce combustion temperature,
keeping overall engine temperature
lower. For this reason, any increase in
the A/F ratio beyond that designed for
at the time of manufacturing, such as
the enleanment resulting from ethanol,
raises potential concerns.
In 1978, EPA issued HC and CO
emission standards for highway
motorcycles. There were no standards
for NOX emissions. To meet these
standards, the vast majority of
motorcycle models used the approach of
adjusting the A/F ratio rather than using
any unique emission control
technologies, such as catalytic
converters, EFI, and air injection. For
performance and durability purposes,
most motorcycles operated with an A/F
ratio that was considerably rich of
stoichiometry. The strategy used to
control HC and CO emissions was to
lean the A/F ratio from these rich values
traditionally used for maximum
performance. As with light-duty motor
vehicles, this strategy resulted in lower
HC and CO emissions, but caused an
increase in NOX emissions. Since there
were no NOX emission standards, the
increased NOX emissions were allowed.
This strategy also resulted in complaints
about vehicle performance and
driveability. As a result, a common
practice was for motorcycle owners to
change the A/F ratio on their own to a
richer setting that improved the
performance concerns, but also possibly
resulted in an exceedance of the
emissions standards. These emission
standards were unchanged until 2006
when more stringent standards for HC
and new standards for NOX were
introduced for MY2008.
Off-highway motorcycles were
unregulated until 2006. Beginning with
MY2006, off-highway motorcycles were
required to meet emission standards for
VerDate Mar<15>2010

Jkt 223001
HC, CO, and NOx emissions. In general,
the overall majority of motorcycles
designed from 1978 through 2006 either
used an A/F ratio leaner than desired for
maximum performance and durability
to comply with highway motorcycle
emission standards or ran rich, in the
case of off-highway motorcycles, to help
cool the engine and protect it from
overheating and failure. The practice of
motorcycle owners adjusting the A/F
ratio to a richer setting to improve
performance and driveability was even
more prevalent in the off-highway
motorcycle sector, especially for
competition motorcycles where
performance is an important attribute.
As E10 fuel has become more
prevalent in the marketplace, many
owners of off-highway and older
highway motorcycles have chosen to
either operate their motorcycles on E0
fuel whenever it is available or have
modified their A/F ratio to a richer
setting. In fact, the internet is full of
blogs of motorcycle owners discussing
concerns with operation on E10 fuel and
ways to avoid these concerns, including
how to change the A/F ratio setting. It
is a violation of the CAA to modify a
certified motorcycle from its certified
configuration. Changing the A/F ratio
from the certified setting would be
considered tampering, yet it is clear it
is practiced in-use.
For highway motorcycles designed to
already operate leaner to comply with
emission standards, the use of E15 fuel
would result in a further leaning of the
A/F ratio. These motorcycles were
designed with an optimized A/F ratio
setting taking into consideration the
delicate balance of emissions,
performance, and engine protection.
Since most of these motorcycles use
carburetors, the A/F ratio is not easily
adjusted to adapt to the increased
amount of oxygen in the A/F mixture.
The additional enleanment of the A/F
ratio could cause an increase in
combustion temperature and ultimately
engine temperature, potentially
resulting in an exceedance of the
emission standards and engine failure.
For off-highway motorcycles that have
typically been designed to operate rich
of stoichiometry for engine protection,
the enleanment of the A/F ratio could
cause an increase in engine temperature
beyond what the engine was designed to
accommodate and ultimately result in
engine failure. As a result of the
increased enleanment resulting from
E15 fuel, more motorcycle owners may
be tempted to adjust the A/F setting of
their motorcycles to protect vehicles
from potential damage resulting in
possible exceedances of the emissions
standards.

In either case, the use of E15 fuel
could cause engine damage and
emission increases for highway
motorcycles built prior to 2008 and for
all off-highway motorcycles, regardless
of age. For highway motorcycles built
after MY2008 there is the possibility
that some models may be able to
successfully accommodate the use E15
fuel. For MY2008 and beyond, there are
a number of models that use EFI and
catalytic converters. The systems are
similar to automotive closed-loop
catalyst systems. However, one of the
advantages to modern Tier 2 light-duty
emission control systems is that they
use very sophisticated fuel trim learning
systems that allow a very precise
‘‘learning and adapting’’ of changes to
the A/F ratio mixture. While many of
today’s motorcycle models use closedloop systems, they do not have the
advanced fuel trim control of today’s
motor vehicles, meaning they would
most likely not be able to accommodate
the enleanment of the A/F ratio in the
same manner as today’s motor vehicles.
Their closed-loop technology is more
similar to that of MY2000 and older
motor vehicles than to current motor
vehicles.
In light of the above, while there is no
actual E15 test data on motorcycles,
EPA believes that any operation of
highway or off-highway motorcycles on
fuel containing E15 could result in
engine damage and emission increases
for highway and off-highway
motorcycles. It also could have the
unintentional result of encouraging
motorcycle owners to violate the CAA
by tampering with the vehicles A/F ratio
setting to improve performance,
driveability, and protect the engine from
damage, while at the same time
significantly increasing hydrocarbon
and CO emissions. Therefore, we are
proposing to prohibit the use of E15 in
all motorcycles (highway and offhighway) but seek comment on our
assessment.
F. Nonroad Engines, Vehicles, and
Equipment (Nonroad Products)
1. Introduction
The nonroad product market is
extremely diverse which makes it
difficult to determine what the impacts
of E15 use might be. However, similar
to older motor vehicles, it appears that
nonroad products may experience
emissions increases related to
enleanment and material compatibility
issues if operated on E15. This is based
in large part on the history of the design
of nonroad products operating on E10 in
relation to the age of those products in
the field, and the implications of
E:\FR\FM\04NOP2.SGM
04NOP2
68076
Federal Register / Vol. 75, No. 213 / Thursday, November 4, 2010 / Proposed Rules
extrapolating this in-use operating
experience with E10 to E15.
The majority of nonroad products are
still carbureted, or have very simplistic
electronic fuel injection which cannot
adjust the engine A/F ratio, and do not
have any onboard diagnostics to
monitor engine performance before
components may fail. The experience of
consumers with E10 in nonroad
products in the 1980s pushed most
manufacturers to take some steps to
address enleanment and E10 material
compatibility issues at that time, either
with changes in engine design or
warnings in consumer owner manuals
(either to avoid ethanol blended fuels or
blends higher than 10%). However, the
design practices and recommendations
varied across the industry due to the
breadth of the nonroad market (as
highlighted in Table VI.F.1–1) and the
wide range of manufacturers,
applications, and markets. The design
practices also continued to evolve over
time in part due to emission
regulations.95 While a review of current
nonroad engine and equipment
manufacturer Web sites indicates a
general acceptance of E10 use with the
new products being produced today,
manufacturers continue to caution
against any higher level ethanol use,
and marine manufacturers still caution
against E10 use.96 In addition, nonroad
product manufacturers are clearly still
learning how to design for compatibility
with E10 as evidenced by a recent large
recall of snowblowers due to corroded
carburetors.97

In addition, as shown in Table
VI.F.1–2, consumers are still using a
considerable amount of older nonroad
products (e.g., marine engines) that are
not necessarily designed for E10 use. In
recognition of this situation, States such
as Minnesota, Missouri, Oregon, and
Washington that have mandated the use
of ethanol blends have also provided
exceptions to the mandate for sale of
ethanol free gasoline (E0) for a variety
of nonroad products. In addition,

compared to prior engines and limit the ability to
manually adjust the A/F ratio, so while newer
engines may use materials better suited for ethanol,
they may also be more susceptible to enleanment
concerns.

2. Enleanment
Given the relatively undeveloped
technological design of the nonroad
product fleet for purposes of emissions
control, one of the main concerns with
the use of E15 in nonroad products, as
for older motor vehicles, is the
increased temperatures caused by
enleanment of the A/F ratio. With
higher levels of ethanol, the
stoichiometric (ideal) A/F ratio becomes
lower (i.e., more fuel is needed for the
same amount of air) due to the increased
oxygen in the fuel; hence, the nonroad
products run leaner since they do not
adjust to the fuel oxygen content.
Engines designed to operate on nonethanol fuels (0 wt% oxygen) are
currently operating on E10, which
typically contains about 3.5–3.7 wt%
oxygen, and would operate on
approximately 5.5 wt% oxygen when
operating on E15. As evidenced by
various studies,99 enleanment has an
immediate impact on emissions, causing
HC and CO emissions to decrease and
NOX emissions to increase. However,
since the HC and NOX impacts are
directionally opposite, these immediate
impacts are of less concern than the
impacts of long-term operation and
durability. Leaner operation increases
cylinder and exhaust temperatures that
can lead to overheating of the engine. In
some cases this can lead to expansion of
the engine block and pistons and result
in a seized engine. Increased
combustion temperature can also result
in expansion and contraction of the
engine block and head metals which
leads to loosening of the head bolts.
With looser bolts, the gap between the
engine block and the head will open
and the head gasket can get damaged,
which in turn damages other engine
components (e.g., intake and exhaust
valves, manifolds, etc.) which can result
in increased emissions and potential
engine failure.
The likelihood that nonroad products
may experience such issues with E15 is
difficult to quantify. However, limited
testing by DOE 100 showed some engine
failures with E15, and this is not
entirely unexpected since nonroad
products are particularly prone to
enleanment for several reasons. First,
nonroad products remain primarily
carbureted and/or have open loop fuel

control.101 This means they do not have
the ability to self-adjust the A/F ratio inuse for the presence of ethanol in the
fuel. The amount of enleanment an
engine experiences in-use depends on
several factors, including manufacturing
variability, engine wear, and,
importantly for E15, the A/F ratio
setting of the engine in comparison to
the setting needed for the fuel the
engine is operating on. Engine
manufacturers set the A/F ratio settings
at the time of production based on a
number of factors including the
emission standards, expected
deterioration of emissions over time and
the emission certification fuels.102 Inuse engines are Federally certified on
E0, while engines certified to California
standards are certified on an MTBE
blend (the equivalent oxygen content of
about E6 or about 2.0 wt% oxygen).103
Thus, when nonroad products switch to
using E10 in the field, they operate
leaner than they were set to operate and
would operate leaner still on E15. Older
nonroad products may have more
headroom to tolerate enleanment from
ethanol than newer engines. This is
because manufacturers have tended to
set the A/F ratio for their newer engines
closer to stoichiometry (less rich) to
meet newer, more stringent emission
standards in recent years.104 Second, the
majority of nonroad products are aircooled (rely on fins designed into the
engine block to dissipate heat and some
have a fan to aid in cooling) and fuelcooled (rely on rich operation -excess
fuel—to cool certain engine components
like exhaust valves and manifolds).
Thus, they are much less forgiving of
temperature increases that might result
from enleanment. Third, nonroad
products frequently operate at wide
open throttle for much of their duty
cycle where exhaust temperatures are
highest.
Additionally, as enleanment occurs,
the potential for an engine to reach its
101 Of the nearly 1200 gasoline-fueled nonroad
engine families certified in 2010, only 36 are
estimated to have closed loop electronic fuel
injection, and most of those are large spark-ignited
nonroad engines.
102 Older nonroad products—those prior to
emission standards—tended to have A/F ratio
adjustment screws so knowledgeable consumers or
maintenance facilities could adjust the A/F ratio of
the engine if it operating poorly. Manufacturers
tended to remove or limit the capability for such
manual adjustments to meet emission standards.
103 Standards for some nonroad categories which
require evaporative emission certification on E10
and allow it as an option for exhaust are just
beginning to phase in.
104 Some engines have been under emission
regulation for 13 years while others are just falling
under emission regulation. In order to meet EPA
emission standards, engines have either been
enleaned and/or taken on engine designs of a more
efficient engine such as a 4 stroke engine.

lean limit is increased. A lean limit is
found when the typical emissions trend
for enleanment (decreased HC and CO
emissions and increased NOX
emissions) reverses and results in
increased HC and CO and decreased
NOX. The reversal of emissions at the
lean limit is a signal the engine is
starting to experience incomplete
combustion and is beginning to
experience misfires, hence the increases
in HC. This often results in engine
failure since the engine cannot operate
for an extended period of time under
this condition. Results from a DOE pilot
study on small SI nonroad products
confirmed the potential enleanment
concerns.105 Several engines failed prior
to reaching their full useful life, and the
emission results for one of these (a
consumer market trimmer) indicated
that it indeed may have exceeded its
lean limit when operating on E15.
Finally, as highlighted above in VI.C.,
catalysts are an emission reduction
technology that is sensitive to increases
in exhaust temperature that would
result from the use of E15. Although not
yet commonly found on nonroad
products, they began phasing-in on
small SI handheld engines in 2002. High
exhaust temperatures are already a
concern with these catalysts due to the
close location of the catalyst to the
combustion chamber (catalysts are
located within the muffler which is
commonly attached to the engine block).
The hotter combustion temperatures
from engine enleanment result in hotter
exhaust temperatures experienced by
the catalyst and can increase the
likelihood of catalyst washcoat
sintering. If sintered, the catalyst
becomes nearly useless. The likelihood
that an engine/catalyst setup would
reach this state is dependent on the
engine/catalyst design and the
production variability. Both of these
vary from engine manufacturer to
engine manufacturer and engine to
engine.
These potential enleanment problems
would also impact the emission
performance of engines operated on E15
over their full useful life. Unfortunately,
emissions data from nonroad products
operated over their full useful life on
E15 is very limited and currently is
known only to exist for the small sparkignition sector of nonroad engines. DOE
performed a pilot and durability study
on four small SI engine models operated

increase for E10) and for a consumer

consumer blower engines tested did not
make it to aging at full useful life on
E15. The blower engines did have
catalysts, however, the study was not
able to analyze its effectiveness over
time. If the catalyst on the blower was
to fail and the engine continued to
operate, then the engine could have
emitted almost the same emissions as
pre-regulation engines (e.g., 100–120 g/
kW-hr without a catalyst vs. 50 g/kW-hr
with a catalyst). Thus, while it was only
a small test sample, it is clearly
suggestive that exhaust emissions may
increase considerably with E15 over the
full useful life of the engines.
Furthermore, while the study was only
conducted on the small SI segment of
the nonroad market, the similarities
between it and most other segments of
the nonroad market would raise similar
concerns.

deterioration of materials could result in
loss of function of critical engine
components, which can result in
emissions increases from fuel leaks and
equipment failure. Nonroad products do
not have onboard diagnostics to detect
these conditions and report it to the user
prior to engine failure. Not much is
known about the use of E15 in nonroad
products in real world use. However,
concern exists because, as discussed
above in section VI.B., ethanol has
different material compatibility
characteristics than gasoline, and even
products operating adequately on E10
today may have issues with E15. In

addition, the vast range of nonroad
product designs and technologies over
the years indicates that material
incompatibility may exist in portions of
the in-use fleet when using E15.
Motor vehicle manufacturers, as
discussed in section VI.G, were driven
by both market forces and EPA emission
standards to redesign motor vehicles
and upgrade materials for continual use
of E10. This is not the case for nonroad
products. We are not aware of any
standard design practices self imposed
by industry in relation to the presence
of ethanol in gasoline either in the early
1980s with gasohol in the Midwest or in
the 2000s as gasoline-ethanol blends
expanded nationwide. As a result, it
appears that manufacturers used a
variety of approaches at different points
in time in response to market
conditions. One reason for this is that
the nonroad market serves a wide range
of consumers—the low cost consumer
quality and the higher cost professional
quality—and the target market may
govern how decisions are made.
Another reason is the vast diversity of
nonroad products as discussed above.
The wide range of engines, applications,
manufacturers, and markets leads to a
wide range of equipment design
practices. Finally, some manufacturers
of nonroad vehicles and equipment may
purchase another manufacturer’s engine
and modify it and/or its fuel system for
a different application (e.g. purchasing a
small SI engine and replacing the fuel
tank with a different design so it fits in
the equipment, or marinizing an
automotive engine for use as a marine
engine and recertifying). Since there
have been no evaporative requirements
for small SI engines until the Phase 3
standards (beginning in 2009), in prior
years the hoses and tanks could be
changed without concern.
Consequently, even engine fuel systems
designed for the presence of ethanol by
the original engine manufacturer may be
compromised by the vehicle/equipment
manufacturer. Thus, it is very difficult
to quantify the volume of nonroad
products in today’s fleet designed to
operate on E10 let alone E15. As shown
in Figure VI.A–1, since E10 now
represents more than 80% of the
gasoline market, it is clearly being used
in nonroad products today. However, as
shown in Figures VI.A–3 and VI.A–4 the
expansion of E10 nationwide is still a
relatively recent event and the effects
we are focused on are effects from
longer term use of the fuel.
Based on manufacturer Web sites and
owner’s manual recommendations, most
new nonroad products produced today
are designed to be compatible with E10.
The main exceptions are marine
PO 00000
Frm 00036
Fmt 4701
Sfmt 4702
applications (as well as aircraft, which
are not nonroad for purposes of section
211(c), but in some cases use the same
gasoline as nonroad products). The
transition appears to have occurred at
different points in time across the
market. However, this is not to say that
these engines have been designed to be
compatible with E15. The effects of
ethanol are time and concentration
dependent such that the effects of E15
may be more severe than E10 on
materials. Consequently, manufacturers,
while approving the use of E10 today,
now also warn against the use of any
higher gasoline-ethanol blends.
Unlike motor vehicles, most nonroad
products are used periodically and not
for daily tasks. Many of these products
are designed to be inexpensive
consumer products that last a relatively
short time or are used irregularly and for
short periods of time. However a
considerable fraction may remain in the
in-use fleet for a long time (10–40+
years). Table VI.F.1–2 shows an
estimated age distribution of nonroad
products in 2010. Marine engines are
separated in the table to illustrate the
fact that these products in particular
remain in the fleet for many years.
Consequently, even if nonroad products
today are designed by the manufacturer
for the presence of 10% ethanol in the
gasoline, a large number of pieces of
equipment still exist in the field from
model years when ethanol was not
present in gasoline, or was just
beginning to be introduced into the fuel
stream. Based on subsequent
experience, some of this equipment may
operate fine on E10, while others may
have complications due to the
enleanment or material incompatibility
effects of using ethanol.
There have been several attempts to
study the material compatibility of E15
use in nonroad engines, vehicles and
equipment. However, the broad range of
equipment and designs over time make
it extremely difficult to do any
definitive study on the nonroad sector
that would address the entire fleet. A
literature and information search
prepared by the University of Minnesota
Center for Diesel Research outlines a
number of the concerns with ethanol
that could be experienced with E15.
—Corrosion of steel is accelerated by the
presence of alcohols in the fuel, both
because the ethanol itself is considered
to be more corrosive but also because it
is a solvent that removes oils and
coatings from the surface that might
protect against corrosion. In addition,
ethanol attracts and mixes with water
which is also corrosive and tends to
create a slightly acidic solution,
especially over time.

—Elastomers exposed to higher
gasoline-ethanol blends over time can
increase in weight gain, swell, soften
and increase in hardness when dried
and as a result lose tensile strength,
causing fuel pumps and fuel lines to
fail. For fuel hoses, swelling and
softening creates a risk of failure of the
joints. The swelling and softening of Orings, seals and gaskets causes a risk of
damage or incorrect fit of the seal during
assembly of joints leading to fuel
leakage.
—Seals and gaskets on equipment that
have not been previously exposed to
higher alcohol fuels could deteriorate
and break down creating leakage.
—Fiberglass-reinforced plastic fuel
tanks, such as those on marine engines
and motorcycles, may also experience
problems depending on the type of resin
and how much the ethanol will
contribute to the corrosion of it.
—Materials such as lead/tin-coated steel
used in fuel tanks and aluminum fuel
system components require corrosion
inhibitors due to the presence of the
higher alcohol in E15.
In addition, four studies have been
reported which tested the effect of a
number of ethanol containing fuels
(E10, E20) on materials compatibility of
polymers, metal, and elastomers in
motor vehicles and nonroad engines.
While none of these studies reported on
E15, a number of reports gave
conditions seen on E10 and E20 and so
results for E15 can be interpolated. The
results of one technical assessment,
published in 2002,108 of E10 and E20 on
two 2-stroke engines indicated materials
compatibility concerns for E20 for both
engine types, including effects on some
polymeric materials that were deemed
unacceptable and E20 tarnishing and
corroding brass and aluminum parts.

by the University of Minnesota

elastomer materials,

vehicles and nonroad products found a
variety of impacts with E20 relative to
E10 or E0, including clear
incompatibility with some materials.
The existence of such materials on
equipment in the in-use fleet could lead
to increased emissions, fuel leaks, and
potentially engine failure from longer
term use of E15. The degree to which
such incompatible materials exist in the
in-use fleet is unknown, but it is clear
that they do exist based on in-use
experience with E10.112, 113
We are not aware of any testing that
has been done that might help quantify
the potential impact on emissions from
the types of engine problems that would
result from material compatibility
problems. However on July 14, 2010 the
United States Consumer Protection
Safety Commission (CPSC) and Health
Canada (HC) announced a recall of Toro
snowblowers stating that ‘‘Exposure to
ethanol in gasoline can cause the
carburetor needle to become corroded.
A corroded needle can stick in the open
position and allow fuel to leak from the
carburetor.’’ 114 Clearly fuel leaks would
result in a considerable increase in
evaporative emissions, and material
issues with carburetors, fuel pumps, and
other engine components could clearly
lead to significant changes in exhaust
emissions, if not engine survivability.
4. Phase Separation and Solvency/
Detergency
Two additional concerns with E10 use
in nonroad products are phase
separation and solvency/detergency (see
section VI.B.). However, if nonroad
products have already been operating on
E10, the degree to which these would be
a concern with E15 is unknown. Phase
separation occurs if a gasoline-ethanol
blend is saturated with water. Phase
separation is more likely in nonroad
products due to the fact that these
engines are typically used only
seasonally or occasionally throughout
the year and in the case of marine
applications, the equipment is generally
in a humid, water environment. In
addition, specifically for small SI
engines, some of the fuel systems are
open to the atmosphere through a direct
vent in the gas cap which exposes the
fuel to air and humidity. If phase

separation occurs, it has been reported
by repair shops to be acidic and result
in corroded carburetors and potential
fuel line leaks. However, while phase
separation has been and continues to be
a significant concern with E10, as
evidenced by ongoing guidance on
manufacturer literature 115 and nonroad
engine Web sites,116 the additional
ethanol in E15 would increase the water
tolerance of the blend and thereby
potentially reduce the frequency of
phase separation occurring.
Similarly, in areas that have
transitioned to E10, problems have
historically also shown up in repair
shops due to the solvency/detergency
characteristics of ethanol. Ethanol has
been known to dislodge sludge and
varnish in the fuel system, causing it to
clog fuel filters and carburetors.
However, if in-use engines have already
been operated on E10, the cleansing
effect of the ethanol may have already
occurred, and transitioning to E15 may
not result in any additional problems.
G. Model Year 2007 and Newer LightDuty Motor Vehicles
MY2007 and newer light-duty motor
vehicles are covered by EPA’s Tier 2
program which established dramatically
more stringent NOX standards. While
the program allowed the standards to
phase in from MY2004 through
MY2009, manufacturer certification data
show that gasoline-fueled motor
vehicles actually reached full
implementation with MY2007. MYs
2004–2006 included a mix of vehicles—
some Tier 2 and some non-Tier 2. Tier
2 motor vehicles are more
technologically advanced and robust
than cars built years ago, are fully
capable of running on E10, and must
have their evaporative emission systems
aged on E10 for durability purposes.
Sophisticated computer systems and
sensors constantly monitor the engine
and the exhaust to be sure that
everything (i.e., the A/F ratio mixture) is
kept at its optimum level. All auto
manufacturers now warrant their new
motor vehicles to operate on E10 or less.
As found in the E15 waiver decision
also published today, we believe on the
basis of testing performed and our own
engineering assessment, that these
MY2007 and newer Tier 2 light-duty
motor vehicles are durable and will
maintain their emission performance
when operated on E15.
To evaluate the impacts of E15 on
Tier 2 motor vehicles, DOE performed a

catalyst durability test program 117 on 19
Tier 2 motor vehicles from high sales
volume models produced by the various
light-duty vehicle manufacturers
throughout 2009 and 2010. The specific
purpose of the test program was to
evaluate the long term effects of E0, E10,
E15, and E20 on catalyst system
durability. However, a number of the
motor vehicles were also torn down and
evaluated for any other impacts E15
may have had, including material
compatibility in the fuel and
evaporative emission control systems.
As discussed in the waiver decision
document, program results indicate that
the changes manufacturers made
(calibration, hardware, etc.) to their
motor vehicles to comply with the Tier
2 standards have enabled the motor
vehicles to operate satisfactorily on E15,
including the ability of their catalysts to
withstand the additional enleanment
caused by E15.
The DOE test program was critical in
supporting the waiver decision.
However, it also serves to confirm our
engineering assessment of the ability of
light-duty motor vehicles to handle E15.
The emission standards that EPA has
implemented over time affecting motor
vehicles have become more and more
stringent (i.e., Tier 0 to Tier 1 to LEV1
and NLEV to Tier 2 and LEV2). In
addition, full useful life requirements
have increased and new test cycles have
been added. To comply with the
stringent Tier 2 standards,
manufacturers must minimize
deterioration of their vehicle emission
control systems over a vehicle’s full
useful life of 120,000 miles. By MY2004,
new test procedures took effect to better
represent actual consumer driving
habits and conditions. These additional
test cycles, coupled with the in-use
testing required under the Compliance
Assurance Program (CAP2000), pushed
manufacturers to develop more robust
emissions control systems (such as
systems using wide range oxygen
sensors) capable of withstanding the
higher temperatures experienced during
these more severe cycles without simply
relying on enriching of the A/F ratio,
causing emissions to rise. With each
new program, manufacturers were
required to improve the efficiency and
durability of emission control hardware
and the methods and control systems
governing hardware performance
causing newer motor vehicles to be able
to accommodate gasoline-ethanol blends
more so than older motor vehicles.

Perhaps the most critical changes
made over time were the changes to the
engine calibrations and catalyst systems
to accommodate changes in the A/F
ratio such as those that occur when
switching to operation on gasolineethanol blends. Evolution in emission
standards prompted corresponding
evolution in motor vehicle emission
control systems. In particular, catalyst
deterioration must be minimized and
catalyst temperatures controlled during
all vehicle operation modes for the
catalyst to work properly (i.e., for it to
maintain the necessary high efficiency
demanded by the Tier 2 standards). Tier
2 motor vehicles, especially the MY2007
and newer motor vehicles, have
improved hardware as well as more
sophisticated emission control systems
and strategies to help maintain catalyst
effectiveness, and an extended motor
vehicle operating range over which
emissions performance must be
maintained. MY2007 and newer motor
vehicles have the ability to precisely
adjust for changes in the A/F ratio and
ultimately maintain peak catalyst
efficiency under almost any condition,
such as exposure to oxygenated fuels
like those containing ethanol. To do so,
some manufacturers incorporated
learned or adaptive fuel trim into their
motor vehicle designs to modulate the
A/F ratio and alleviate catalyst
temperature increases even under open
loop conditions. Others, through careful
hardware selection and certain
calibration approaches, have motor
vehicle designs with higher thermal
margins to accommodate the effects of
enleanment with gasoline-ethanol
blends.
Prior to completion of the DOE
catalyst durability test program some
concern had been expressed that when
operated on E15, vehicles, even Tier 2
motor vehicles that did not apply
learned fuel trim, may experience
catalyst degradation and higher
emissions over time due to the higher
exhaust temperatures it may cause.
Several screening studies had measured
exhaust and catalyst temperature and/or
evaluated the ability of vehicles to apply
learned fuel trim to adjust for the
enleanment due to ethanol during open
loop operation.118, 119 They had found
that those vehicles that did not apply
learned fuel trim tended to experience
higher catalyst and exhaust

temperatures when operated on E15.
However, as evidenced by the DOE
catalyst durability test program, at least
for Tier 2 motor vehicles this does not
appear to be the case. Even those
vehicles that do not apply learned fuel
trim appear to have sufficient thermal
margins. Therefore, not only do all
manufacturers warrant their Tier 2
motor vehicles for operation on E10, but
as discussed in the waiver decision
document, we believe that they will also
operate properly on gasoline-ethanol
blends up to E15.
With respect to evaporative emissions
control, evaporative systems have had
leak detection diagnostic requirements
since at least MY2000 as a result of the
Agency’s Onboard Diagnostic (OBD)
program. In addition, CAP2000 which
took effect with MY2001 motor vehicles
placed more emphasis on the ‘‘in-use’’
performance of motor vehicle emission
controls with motor vehicles operating
nationwide on the different available
fuels. This emphasis on real world
motor vehicle testing prompted
manufacturers to consider different
available fuels, including gasolineethanol blends, when developing and
testing their emission systems.
However, even with the CAP2000
requirements, some materials issues
continued to arise during in-use
emissions testing. Consequently, as part
of the new Tier 2 standards, EPA added
the requirement that the evaporative
control system and all related
components (i.e. fuel tanks, fuel lines,
etc.) demonstrate durability over their
full useful life while operating on E10.
Due to this new requirement, materials
that would compromise evaporative
emission compliance over the full
useful life with exposure at E10 levels
were eliminated as options for fuel
system components. This requirement,
coupled with much more stringent
evaporative emission standards (over a
50% reduction for passenger cars and
light trucks), was phased-in with the
Tier 2 exhaust standards. Prior to Tier
2, materials are believed to have also
been selected for ethanol compatibility
but perhaps not for continuous exposure
over the full useful life. Based on
conversations with original equipment
manufacturer parts suppliers, it is our
understanding that in designing
materials for continuous E10 exposure,
they tested materials, components, and
systems using ethanol levels in excess of
20% to ensure compatibility with E10.
Consequently, Tier 2 motor vehicle
designs should also be designed to be
compatible with E15, and the results of
the DOE catalyst durability test program
served to confirm this belief.

H. Model Year 2001–2006 Motor
Vehicles
For MY2001–2006 motor vehicles,
both our engineering assessment and the
available data make it less clear whether
motor vehicles produced during those
model years could have emission
increases from long-term fueling with
E15 like MY2000 and older motor
vehicles or whether they would
continue to function properly like
MY2007 and newer motor vehicles. On
the one hand, we believe that many of
the same elements for ethanol
compatibility of MY2007 and newer
motor vehicles also apply to these motor
vehicles (e.g., designing to enhanced
evaporative emission standards, SFTP,
CAP2000). On the other hand, they were
not all required to demonstrate
evaporative emission system durability
on E10 or to upgrade their catalyst and
emission control systems to the extent
needed to comply with the Tier 2
standards. The NLEV standards that
began phasing in with MY2001 required
improvements in closed loop A/F ratio
control and catalyst efficiency, but the
Tier 2 standards represented a
considerable step change beyond NLEV.
Furthermore, as discussed below, while
there are some ongoing test programs
evaluating the effects of E15, we do not
yet have sufficient data that would serve
to confirm or deny any engineering
analysis of the situation, and in
particular to address the potential
concerns raised over those motor
vehicles that do not apply learned fuel
trim during open loop operation.
Two studies that might help inform
the situation are currently still in
process. The Rochester Institute of
Technology is conducting a study of 10
motor vehicles spanning MY1998–2004
on E20 and is operating roughly 300
motor vehicles in-use on E20.120 While
the results of this study to date suggest
vehicles may operate acceptably on
E20—and by interpolation E15—mileage
accumulation is limited, so its ability to
assess emission impacts over the FUL of
the vehicles is also limited. In addition,
since there are no control vehicles
operating on E0, comparisons of
emission effects are restricted. The
study is ongoing until November 2010.
In addition, DOE is in the process of
conducting catalyst durability testing on
six motor vehicles certified to NLEV
standards and two motor vehicles
certified to Tier 1 standards which will
also be completed by November. Since
the motor vehicles are older, they are

starting the test program with a
significant number of miles already
driven by consumers on E0. However, at
least 50,000 miles are being
accumulated on each motor vehicle, and
identical motor vehicles of the same
model are being tested on E0, E10, E15,
and E20.
I. Emissions Impact Summary and
Conclusions
As discussed above, the potential
exists for E15 use to cause long-term or
permanent increases in exhaust
emissions from MY2000 and older lightduty motor vehicles, heavy-duty
gasoline engines and vehicles,
motorcycles, and nonroad products, as a
result of accelerated deterioration of
engine and emission control
components. This deterioration can be a
result of changes in engine operation,
such as higher exhaust temperature, or
damage to materials not compatible
with E15. Similarly, evaporative
emission increases may occur
immediately due to increased
permeation or over time due to repeated
or on-going exposure of the fuel and
evaporative emission control systems to
E15. In some cases the potential
emission impacts could be quite
dramatic (i.e., more than an order of
magnitude) given the large differences
between controlled and uncontrolled
emissions on today’s light-duty motor
vehicles, heavy-duty gasoline engines
and vehicles, motorcycles, and nonroad
products. Consequently, the in-use
emissions increases and air quality
impact could be substantial for any of
these products that experience very
significant deterioration.
While it is not possible to quantify the
frequency at which all of these products
might experience problems with the use
of E15, the degree of emissions increases
associated with them, or the
effectiveness of the proposed misfueling
mitigation measures, we believe that the
emission related problems would occur
with enough frequency that the
resulting emission benefits from the
avoided misfueling would clearly
outweigh the relatively low cost
imposed by the proposed regulations.
The emission benefits are the emissions
increases from longer term use of E15
that would not occur because of this
misfueling mitigation program. This is
particularly the case considering the
significant consumer savings for
avoided repairs and replacement that, as
discussed in section III.F., would by
themselves be expected to exceed the
costs of the misfueling mitigation
measures.
For these reasons, the Agency
proposes to prohibit the use of gasoline

blended with greater than 10 vol%
ethanol in (1) MY2000 and older motor
vehicles, (2) heavy-duty gasoline
engines and vehicles, (3) motorcycles,
and (4) nonroad products. Today’s
prohibitions and other requirements are
intended to reduce emissions due to the
use of E15 in the group of vehicles or
engines reasonably expected to have
these adverse effects. The term
misfueling describes use of E15 in the
prohibited engines, vehicles and
equipment listed above. We are inviting
comment on whether this prohibition
should also apply for MY2001–MY2006
motor vehicles.
VII. What is our legal authority for
proposing these misfueling mitigation
measures?
As explained above, we are proposing
misfueling mitigation measures
pursuant to our authority under CAA
section 211(c)(1). This section gives EPA
authority to ‘‘control or prohibit the
manufacture, introduction into
commerce, offering for sale, or sale’’ of
any fuel or fuel additive (A) whose
emission products, in the judgment of
the Administrator, cause or contribute
to air pollution ‘‘which may be
reasonably anticipated to endanger
public health or welfare’’ or (B) whose
emission products ‘‘will impair to a
significant degree the performance of
any emission control device or system
which is in general use, or which the
Administrator finds has been developed
to a point where in a reasonable time it
would be in general use’’ were the fuel
control or prohibition adopted. Under
section 211(c)(1), EPA may adopt a fuel
control if at least one of the two criteria
above are met. We are proposing the
misfueling mitigation measures based
on both of these criteria. Under section
211(c)(1)(B), we believe that E15 would
significantly impair the emission
control systems used in MY2000 and
older light-duty motor vehicles, heavyduty gasoline engines and vehicles,
highway and off-highway motorcycles,
and all nonroad products. This leads us
to conclude, under section 211(c)(1)(A),
that the likely result would be increased
HC, CO and NOx emissions when these
particular engines, vehicles and
nonroad products use E15. The
following sections summarize our
analysis of each criterion.
A. Health and Welfare Concerns of Air
Pollution Caused by E15
We believe that the emissions
products of E15 contribute to air
pollution that can reasonably be
anticipated to endanger public health
and welfare. As described in Section

properties of ethanol may negatively
impact certain engines, vehicles and
equipment when those products use
gasoline-ethanol blends containing
increased amounts of ethanol,
particularly if those engines, vehicles
and equipment are not designed for
accommodating that increase. The result
is likely an increase in HC, CO and NOx
emissions from these engines, vehicles
and equipment (see Sections VI.C.–F.).
This potential increase in emissions of
these particular pollutants contributes
to air pollution levels that, for example,
can violate the NAAQS for ozone or PM.
Section 211(c)(2)(A) requires that,
prior to adopting fuel controls based on
a finding that the fuel’s emission
products contribute to air pollution that
can reasonably be anticipated to
endanger public health or welfare, EPA
consider ‘‘all relevant medical and
scientific evidence available, including
consideration of other technologically or
economically feasible means of
achieving emission standards under
[section 202 of the Act].’’ EPA’s analysis
of the evidence relating to the emissions
impact of emissions from E15 is
described in Section VI above, while the
evidence concerning the NAAQS is
discussed in the NAAQS rulemakings
themselves.
EPA has also satisfied the statutory
requirement to consider ‘‘other
technologically or economically feasible
means of achieving emission standards
under section [202 of the Act].’’ This
provision has been interpreted as
requiring consideration of establishing
emissions standards under section 202
prior to establishing controls or
prohibitions on fuels or fuel additives
under section 211(c)(1)(A). See Ethyl
Corp. v. EPA, 541 F.2d 1, 31–32 (DC Cir.
1976). In Ethyl, the Court stated that
section 211(c)(2)(A) calls for good faith
consideration of the evidence and
options, not for mandatory deference to
regulation under section 202 compared
to fuel controls. Id. at 32, n.66. For
MY2000 and older motor vehicles,
proposing emissions standards under
section 202 is not an option since
emissions standards promulgated under
section 202 only apply to new motor
vehicles. This is also true for the other
categories (heavy-duty gasoline engines
and vehicles, highway and off-highway
motorcycles, and all nonroad products)
to the extent these products are already
in the marketplace. Thus, for all of these
products, the proposed measures under
section 211(c)(1) are appropriate for
addressing misfueling. Additionally,
EPA has previously promulgated the
most technologically and economically
feasible HC, CO and NOX emissions
standards for all of these engines,
VerDate Mar<15>2010
18:58 Nov 03, 2010
Jkt 223001
vehicles and equipment, so new
emissions standards under section 202
for any of these products would not
achieve any additional protection
beyond those obtained through the
misfueling mitigation measures being
proposed today under section 211(c)(1).
It is therefore appropriate for EPA to
exercise its authority under section
211(c)(1)(A) and propose these
misfueling mitigation measures that will
likely reduce or eliminate the emissions
products from E15 that contribute to the
air pollution that endangers our public
health or welfare.
B. Impact of E15 Emission Products on
Emission Control Systems
EPA believes that E15 can
significantly impair the emissions
control technology in MY2000 and older
light-duty motor vehicles, heavy-duty
gasoline engines and vehicles, highway
and off-highway motorcycles, and all
nonroad products. As discussed in
Section VI above, ethanol enleans the
A/F ratio; this may lead to emissions
products that can cause increased
exhaust gas temperatures and, over
time, incremental deterioration of
emission control hardware and
performance. Enleanment can also lead
to catalyst failure. Additionally, ethanol
can cause material compatibility issues
which may lead to other component
failure. Ultimately, all of these impacts
would likely significantly impair the
emissions control systems or devices
and lead to exhaust and/or evaporative
emission increases.
Section 211(c)(2)(B) requires that,
prior to adopting a fuel control based on
a significant impairment to emission
control systems, EPA consider available
scientific and economic data, including
a cost benefit analysis comparing
emission control devices or systems
which are or will be in general use that
require the proposed fuel control with
such devices or systems which are or
will be in general use that do not require
the proposed fuel control. This
provision is not applicable to the
proposed misfueling mitigation
measures since a particular emission
control device or system is not required
for use with the measures being
proposed today. Instead, the misfueling
mitigation measures are being proposed
to protect existing controls on existing
engines, vehicles and equipment
already in the marketplace from the
detrimental impacts they may incur
when using E15.
Thus, EPA may exercise its authority
under section 211(c)(1)(B) and propose
these misfueling mitigation measures
since use of E15 would significantly
impair the emission control devices or
PO 00000
Frm 00040
Fmt 4701
Sfmt 4702
systems in MY2000 and older light-duty
motor vehicles, heavy-duty gasoline
engines and vehicles, highway and offhighway motorcycles, and all nonroad
products.
C. Effect of Misfueling Mitigation
Measures on the Use of Other Fuels or
Fuel Additives
Section 211(c)(2)(C) requires that,
prior to prohibiting a fuel or fuel
additive, EPA establish that such
prohibition will not cause the use of
another fuel or fuel additive ‘‘which will
produce emissions which endanger the
public health or welfare to the same or
greater degree’’ as the prohibited fuel or
fuel additive. Even assuming that this
proposal amounts to a prohibition, as
compared to a control, EPA does not
believe that the proposed misfueling
mitigation measures will result in the
use of any other fuel or fuel additive
that will produce emissions that will
endanger public health or welfare to the
same or greater degree as the emissions
produced by E15. In fact, the measures
being proposed today should lessen the
overall public health or welfare impacts
from the emissions from these products.
To the extent that EPA is proposing a
prohibition of using E15 in certain
engines, vehicles and equipment, such a
prohibition should serve to prevent or
reduce misfueling in those products and
avoid the increased detrimental effects
this provision seeks to protect against.
These products would instead use other
gasoline or gasoline-ethanol blends
currently available in the marketplace
and be able to meet their current
emissions standards. Thus, EPA may
propose these misfueling mitigation
measures under 211(c)(1) without
causing other public health or welfare
effects from the use of another fuel or
fuel additive.

XI. Statutory and Executive Order
Reviews
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.’’ This action may raise novel
legal or policy issues. 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.
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)
document prepared by EPA has been
assigned EPA ICR number 2408.01.
This proposed rule imposes some new
information collection burdens
regarding product transfer
documentation. Product transfer
documents, or PTDs, are commonly
used in the fuels distribution system
and are their use is a customary
business practice. This proposed rule is
expected to add a one-time burden to
program and implement new product
codes and statements, as well as a
continuing, small burden associated
with affixing (using) products codes and
statements. This proposed regulation
contains provisions requiring standard
product labels, which will not impose
any information collection burden on
regulated parties. We have also
estimated the burden associated with
parties who elect to use proposed
‘‘Survey Option 1.’’
For the proposed information
collection, we estimate that there will be
9,608 annual respondents; 2,009,226
annual responses; and 71,809 annual
hours. We estimate that annual cost of
this information collection to
respondents will be $5,098,427. The
average burden is 0.04 hours per
response. Burden is defined at 5 CFR
1320.3(b).
We estimate that the cost of adding
the proposed survey of compliance

srobinson on DSKHWCL6B1PROD with PROPOSALS2
(which requires sampling and testing)
with the proposed labeling requirements
to the existing RFG survey at $50,000
per year. The cost to implement all of
the proposed survey provisions for
conventional gasoline is estimated at $2
million per year. Thus, the total cost of
the proposed survey requirements is
estimated to be $2.05 million per year
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–2010–0448.
Submit any comments related to the ICR
to EPA and OMB. See 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 November 4, 2010 a
comment to OMB is best assured of
having its full effect if OMB receives it
by December 6, 2010. 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 today’s rule on small entities, small
entity is defined as: (1) A small business
as defined by the Small Business
Administration’s (SBA) regulations at 13
CFR 121.201; (2) a small governmental
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
VerDate Mar<15>2010
18:04 Nov 03, 2010
Jkt 223001
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. The small entities directly
regulated by this proposed rule are
petroleum refiners and importers,
ethanol producers, ethanol blenders,
gasoline terminals, gasoline stations
with convenience stores, and other
gasoline stations. While there are small
entities in each of these market sectors
as discussed in Section III.F., the cost
impact on any particular entity is
expected to be a tiny fraction of annual
revenues.
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.
Association of Clean Air Agencies
(NACAA) to discuss the nature of
today’s proposed rule. Additionally, we
provided State and local governments
an opportunity to provide comment on
the implementation of misfueling
mitigation measures for a partial E15
waiver in both the RFS2 NPRM (see 74
FR 25016) and the E15 waiver request
notice (see 74 FR 18228). We received
comments from only one State on this
issue in the RFS2 NPRM, and it
supported efforts for properly labeling
fuel pumps containing gasoline-ethanol
blends. Thus, Executive Order 13132
does not apply to this action. 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
action from State and local officials.
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. The total annual cost is
expected to be $6 million. Thus, this
rule is not subject to the requirements
of sections 202 or 205 of UMRA.
This rule 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. This
action primarily affects the private
sector, specifically petroleum refiners
and importers, ethanol producers,
ethanol blenders, gasoline terminals,
gasoline stations with convenience
stores, and other gasoline stations.
This action does not have Tribal
implications, as specified in Executive
Order 13175 (65 FR 67249, November 9,
2000). This rule will be implemented at
the Federal level and impose
compliance costs only on petroleum
refiners and importers, gasoline stations
with convenience stores, and other
gasoline stations. Thus, Executive Order
13175 does not apply to this action.
E. Executive Order 13132 (Federalism)
EPA believes that this action does not
have federalism implications. This rule
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 Executive Order 13132. Any
preemption of State or local controls
under section 211(c)(4)(A), based on
issuance of this rule under section
211(c)(1), would only apply to State or
local controls adopted for purposes of
motor vehicle emissions control.
EPA consulted with State and local
officials early in the process of
developing the proposed action to
permit them to have meaningful and
timely input into its development. EPA
met with members of the National

G. Executive Order 13045: Protection of
Children From Environmental Health
Risks and Safety Risks
EPA interprets EO 13045 (62 FR
19885, April 23, 1997) as applying only
to those regulatory actions that concern
health or safety risks, such that the
analysis required under section 5–501 of
the EO has the potential to influence the
regulation. This action is not subject to
EO 13045 because it does not establish
an environmental standard intended to
mitigate health or safety risks.
H. Executive Order 13211: Actions
Concerning Regulations That
Significantly Affect Energy Supply,
Distribution, or Use
This action is not a ‘‘significant energy
action’’ as defined in Executive Order
13211 (66 FR 28355 (May 22, 2001)),
because it is not likely to have a
significant adverse effect on the supply,
distribution, or use of energy. This
proposed rule would require a label to
be placed on E15 fuel dispensers, for
those stations that elect to sell E15. The
cost of the labels would average $6.45
per year per gasoline station. This is a
tiny fraction of the station’s annual
profit, and is not expected to
significantly affect energy distribution.

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. NTTAA directs EPA to provide
Congress, through OMB, explanations
when the Agency decides not to use
available and applicable voluntary
consensus standards.
This proposed rulemaking does not
involve technical standards. Therefore,
EPA is not considering the use of any
voluntary consensus standards.

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.
This action would affect all gasoline
stations that choose to sell E15 and
therefore will not affect any particular
area disproportionately.

Regulation To Mitigate the Misfueling of Vehicles and Engines
With Gasoline Containing Greater Than Ten Volume Percent Ethanol and
Modifications to the Reformulated and Conventional Gasoline Programs
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA is proposing a regulatory program to help mitigate the
potential for misfueling of certain engines, vehicles and equipment
with gasoline containing greater than 10 volume percent (``vol%'')
ethanol up to 15 vol% ethanol (E15). This proposal is in conjunction
with the Agency's partial waiver, pursuant to Clean Air Act section
211(f)(4), which allows for the introduction into commerce of gasoline-
ethanol blends containing up to 15 vol% ethanol for use in model year
2007 and newer on-highway light-duty motor vehicles. The E15 waiver is
limited in scope to a portion of the light-duty fleet, and the proposed
misfueling mitigation program will help avoid the misfueling of all
other engines, vehicles, and equipment with unapproved fuels. This
proposed rule would require all E15 gasoline fuel dispensers to have a
label if a retail station chooses to sell E15 and seeks comment on
separate labeling requirements for fuel blender pumps and fuel pumps
that dispense E85. Similar to the prohibition in section 211(f)(1), the
proposed rule would prohibit the use of gasoline containing greater
than 10 vol% ethanol in vehicles and engines not covered by the partial
waiver for E15. In addition, the proposed rule would require product
transfer documents specifying ethanol content and Reid Vapor Pressure
(RVP) to accompany the transfer of gasoline blended with ethanol and a
national survey of retail stations to ensure compliance with the these
requirements. The proposed rule would also modify the Reformulated
Gasoline (``RFG'') program by updating the Complex Model to allow fuel
manufacturers to certify batches of gasoline containing up to 15 vol%
ethanol.

I. Overview
In today's action, the U.S. Environmental Protection Agency (EPA or
the Agency) is proposing regulations to mitigate the potential for
misfueling of vehicles and engines with gasoline containing up to 15
vol% ethanol (E15).\1\ These regulations are being proposed in
conjunction with today's action by EPA granting of a partial waiver for
ethanol blends up to 15 vol% ethanol under section 211(f)(4) of the
Clean Air Act (CAA or the Act). This partial waiver will allow the
introduction into commerce of E15 for use in 2007 model year (MY) and
newer light-duty motor vehicles. In partially granting the E15 waiver,
EPA imposed a number of conditions on the refiners and renewable fuel
producers subject to the waiver. These conditions are designed to help
ensure that E15 is introduced into commerce for use in MY2007 and newer
light-duty motor vehicles and flexible-fueled vehicles, and not for use
in any other vehicles or engines. Some of the regulatory provisions
proposed today parallel those conditions and are expected to be a more
efficient way to help ensure that the conditions of the E15 partial
waiver decision are met and to minimize in-use emissions increases that
might result from misfueling vehicles and engines with E15. The
proposed safeguards would also promote the successful introduction of
E15 into commerce.
---------------------------------------------------------------------------
\1\ For purposes of this preamble, E15 refers to gasoline-
ethanol blended fuels that contain greater than 10 vol% and no more
than 15 vol% ethanol content.
---------------------------------------------------------------------------
We are proposing four requirements as part of our misfueling
mitigation regulations. The first requirement, consistent with the
partial waiver being granted today, is a prohibition against using E15
in MY2000 and older motor vehicles, heavy-duty gasoline engines and
vehicles, on and off-highway motorcycles,\2\ and nonroad engines,
vehicles, and equipment.\3\ This prohibition is similar in nature to
the prohibition on producers of fuels and fuel additives under section
211(f)(1); however, the prohibition in section 211(f)(1) only applies
to these upstream parties. The prohibitions proposed today would apply
at the retail level as well as upstream. The conditions on the partial
waiver and the regulations proposed today are similar in nature and
have a common goal--ensuring that E15 is used in appropriate motor
vehicles covered by the partial waiver, and is not used in other motor
vehicles and engines. Since the Agency is deferring a decision for
MY2001-2006 light-duty motor vehicles, we are not proposing a
prohibition with respect to the fuel used in these motor vehicles at
this time. DOE testing of MY2001-2006 light-duty motor vehicles is
ongoing and EPA expects to make a waiver determination for these
vehicles shortly after the results of the DOE testing are available. If
EPA does not grant an E15 waiver for MY2001-2006 light-duty motor
vehicles, then we would expect to include the same prohibitions for
these MY motor vehicles in the final rulemaking.
---------------------------------------------------------------------------
\2\ For purposes of this preamble on and off-highway motorcycles
are referred to collectively as ``motorcycles.''
\3\ For purposes of this preamble, nonroad engines, vehicles,
and equipment are referred to as ``nonroad products.''
---------------------------------------------------------------------------
Second, we are proposing labeling requirements for fuel pumps that
dispense E15 to effectively inform consumers regarding the appropriate
fuel to be used in vehicles and engines. Third, EPA proposes that
product transfer documents (PTDs) from refiners, gasoline terminals,
and oxygenate blenders specify the ethanol content or approved level of
ethanol addition, of the fuel being sold to retail stations or
wholesale purchaser-consumer to ensure that retail stations and
wholesale purchaser-consumers know the level of ethanol content they
are buying so that, in turn, the retail pumps can be properly labeled.
Fourth, EPA proposes a national survey requirement on ethanol producers
and the blenders of E15 (e.g., refiners, gasoline terminals, oxygenate
blenders) to ensure that retail station pumps are in fact being labeled
properly. EPA is seeking comment on including an RVP component to this
national E15 labeling survey to help ensure that summertime RVP
requirements are being met throughout the gasoline distribution chain.
To avoid confusion for consumers when pumps are not labeled, the Agency
is also seeking comment on requiring the labeling of non-E15 pumps. The
Agency has used such misfueling mitigation strategies to implement
several fuel programs over the past thirty years, including the
unleaded gasoline program, the RFG program, and the diesel sulfur
program. The Agency believes that the misfueling mitigation measures
proposed in this rulemaking, coupled with the E15 waiver and a
substantial consumer education and outreach effort by industry, can be
an effective strategy to help reduce misfueling and the associated
emissions impacts while enabling the use of E15 in appropriate
vehicles.
The misfueling mitigation program proposed today generally mirrors
the misfueling conditions in today's partial waiver decision. While the
waiver provides an opportunity for a fuel or fuel additive manufacturer
to meet the conditions, the Agency believes that the proposed
safeguards would provide the most practical method of addressing the
purposes and satisfying the conditions of today's partial waiver
decision.
These misfueling mitigation regulations are proposed under CAA
section 211(c), based on the projected emission increases that would be
avoided by deterring the use of E15 in older motor vehicles, heavy-duty
gasoline engines and vehicles, motorcycles and nonroad products.
Engineering judgment supported by test data, where available, forms the
basis for our technical review and conclusions. Our engineering
assessment described in Section VI identifies a number of emissions
related concerns with the long-term use of E15 in MY2000 and older
light-duty motor vehicles, heavy-duty gasoline engines and vehicles,
motorcycles, and nonroad products. For motor vehicles these concerns
include the potential for catalyst deterioration or catalyst failure as
well as material compatibility issues that could lead to extremely
elevated exhaust and evaporative emissions. For nonroad products and
for motorcycles the misfueling concerns include not only the potential
for elevated exhaust and evaporative emissions but also the potential
for engine failure from overheating. While it is not possible to
quantify precisely the frequency at which motor vehicles and nonroad
products might experience these problems with the use of E15, we
believe that emissions related problems could potentially occur with
enough frequency that the resulting emission benefits from avoiding
misfueling would outweigh the relatively low cost imposed by the
proposed regulations. This would justify the proposed rule,
[[Page 68047]]
even if a very low percentage of vehicle and engines experiences
problems.
As described below in Section VI and in the E15 partial waiver
decision document,\4\ our assessment indicates that manufacturers have
designed at least MY2007 and newer light-duty motor vehicles to be
durable for use on gasoline blends up to E15. This conclusion is
primarily based on the recently completed catalyst durability test
program conducted by the Department of Energy (DOE) wherein they tested
19 vehicle models representative of the Tier 2 motor vehicle fleet out
to their full useful life. The study found that Tier 2 motor vehicles
continued to meet their emissions standards after operating on E15 for
full useful life mileage accumulation. Additionally, according to our
analysis of the DOE test data, for Tier 2 motor vehicles we found no
statistically significant increases in the emissions of regulated
pollutants for motor vehicles operating on E15, and no apparent
material compatibility issues, when compared to vehicles that were
operated on E0.\5\ These results confirm our engineering assessment
that MY2007 and newer motor vehicle's emissions should be less
sensitive to the increased ethanol content in E15. This engineering
assessment is based on the advances in motor vehicle materials and
technology in response to in-use experience with E10 and the
requirement that motor vehicles comply with a series of important new
EPA emission requirements over the years, e.g., enhanced evaporative
emission standards and E10 durability testing, supplemental FTP
emission standards, CAP2000 in-use durability requirements, and the
Tier 2 motor vehicle standards themselves.

---------------------------------------------------------------------------
For MY2001-2006 light-duty motor vehicles, it is currently less
clear whether they could experience significant emission increases when
fueled on E15 like MY2000 and older motor vehicles, or continue to
function properly like the newer 2007 and newer motor vehicles. On the
one hand we believe that many of the same elements for ethanol
compatibility of MY2007 and newer light-duty motor vehicles also apply
to MY2001-2006 light-duty motor vehicles (e.g., enhanced evaporative
emission standards, SFTP, CAP2000). On the other hand, they were not
all required to demonstrate evaporative emission system durability on
E10 or to upgrade their catalyst and emission control systems to the
extent needed to comply with the Tier 2 standards. Furthermore,
currently available test data on these model year vehicles is much more
limited. DOE is in the process of developing relevant data for these
model year vehicles. Specifically, DOE is conducting catalyst
durability testing on six motor vehicle models certified to NLEV
standards and two motor vehicles certified to Tier 1 standards
scheduled to be completed in November, 2010. Additionally, a study of
in-use motor vehicles by Rochester Institute of Technology on E20 \6\
suggests such motor vehicles may operate acceptably on E20--and by
interpolation E15. However, the mileage accumulation of RIT test
vehicles is limited and the study is still ongoing until November 2010.
This additional information, as well as information gathered through
comment on this proposal and any final decision on a section 211(f)
waiver for MY2001-2006 light-duty motor vehicles, will be considered in
the decisions made for the final rule.

---------------------------------------------------------------------------
In addition to misfueling mitigation measures, today's action also
proposes slight modifications to the Reformulated Gasoline and
Antidumping fuels programs to open the way for refiners and importers
to produce and certify gasoline containing up to 15 vol% ethanol. To
measure compliance with the RFG and anti-dumping standards, the
emissions performance of gasoline is calculated using a model, called
the Complex Model, which predicts the emissions of each regulated
pollutant based on the measured values of certain gasoline properties.
For gasoline to be sold in the U.S., it must comply with the RFG and
Antidumping standards and refiners are required to certify that their
fuel meets the standards by using the Complex Model. Currently, the
equations in the model are limited to an oxygen content of no more than
4.0% by weight in gasoline, which is the maximum possible amount of
oxygen in E10. EPA is proposing to modify the Complex Model to allow
fuel manufacturers to certify batches of E15 fuel.
Finally, EPA proposes to require that Reid Vapor Pressure (RVP) be
identified on PTDs from fuel refineries to oxygenate blenders for
conventional gasoline to ensure that EPA summertime RVP requirements
are met. This is necessary because the waiver announced today is for
blends that meet the summertime gasoline volatility standards for
conventional gasoline.\7\ In order to introduce a fuel that meets both
the Federal summertime RVP standards and contains between 10 and 15
vol% ethanol, fuel refiners would have to create a fuel or blendstock
that has approximately 1.0 psi lower RVP than a fuel or blendstock
intended for E10 due to the interaction between gasoline volatility and
ethanol when blended. Oxygenate blenders would need to know the RVP of
a blendstock or have the intended ethanol content of a blendstock be
specified on the PTD to ensure that they know the correct amount of
ethanol that should be blended into a fuel. The Agency is not proposing
to change RFG PTD requirements found at 40 CFR 80.77 since RVP is
carefully controlled throughout the distribution chain in order to
comply with summertime RFG VOC emissions performance standards.

waiver.
---------------------------------------------------------------------------
II. Background
A. Statutory Authority
CAA section 211(f)(1) makes it unlawful for any manufacturer of any
fuel or fuel additive to first introduce into commerce, or to increase
the concentration in use of, any fuel or fuel additive for use in motor
vehicles manufactured after model year 1974 unless it is substantially
similar to any fuel or fuel additive utilized in the certification of
any model year 1975, or subsequent model year, vehicle or engine under
section 206 of the Act.
Section 211(f)(4) of the Act provides that upon application by any
fuel or fuel additive manufacturer, the Administrator may waive the
prohibition of section 211(f)(1). A waiver may be granted if the
Administrator determines that the applicant has established that the
fuel or fuel additive, and the emission products of such fuel or fuel
additive, will not cause or contribute to a failure of any emission
control device or system (over the useful life of the motor vehicle,
motor vehicle engine, nonroad engine or nonroad vehicle in which such
device or system is used) to achieve compliance with the emission
standards to which the vehicle or engine has been certified. In other
words, the Administrator may grant a waiver for an
[[Page 68048]]
otherwise prohibited fuel or fuel additive if the applicant can
demonstrate that the fuel or fuel additive will not cause or contribute
to engines, vehicles or equipment failing to meet their emissions
standards over their useful life.
EPA previously issued a ``substantially similar'' interpretive rule
for unleaded gasoline which allows oxygen content up to 2.7% by weight
for certain ethers and alcohols.\8\ E10 contains approximately 3.5%
oxygen by weight, which means E10 is not ``substantially similar'' to
certification fuel under the current interpretation. As explained at 44
FR 20777 (April 6, 1979), E10 received a waiver of the substantially
similar prohibition by operation of law since EPA did not grant or deny
a waiver request for a fuel containing 90% unleaded gasoline and 10%
ethyl alcohol within 180 days of receiving that request. This waiver by
operation of law was based on the then current terms of CAA section
211(f)(4), which has subsequently been amended.
---------------------------------------------------------------------------
\8\ See 56 FR 5352 (February 11, 1991).
---------------------------------------------------------------------------
Section 211(c)(1) of the Act allows the Administrator, by
regulation, to ``control or prohibit the manufacture, introduction into
commerce, offering for sale, or sale of any fuel or fuel additive for
use in a motor vehicle, motor vehicle engine, or nonroad engine or
nonroad vehicle (A) if, in the judgment of the Administrator, any fuel
or fuel additive or any emission product of such fuel or fuel additive
causes, or contributes, to air pollution or water pollution (including
any degradation in the quality of groundwater) that may reasonably be
anticipated to endanger the public health or welfare, or (B) if
emission products of such fuel or fuel additive will impair to a
significant degree the performance of any emission control device or
system which is in general use, or which the Administrator finds has
been developed to a point where in a reasonable time it would be in
general use were such regulation to be promulgated.'' Today's proposed
misfueling regulations are based on this authority in section
211(c)(1), as well as our recordkeeping and information collection
authority under sections 208 and 114.
B. E15 Waiver Request
On March 6, 2009, Growth Energy and 54 ethanol manufacturers
submitted an application to EPA for a waiver under section 211(f)(4) of
the CAA. This application sought a waiver for ethanol-gasoline blends
of up to 15 vol% ethanol.\9\ On April 21, 2009, EPA published notice of
the receipt of the application, and, as required by CAA section
211(f)(4) of the Act, EPA requested public comment on all aspects of
the waiver application, to assist the Administrator in determining
whether the statutory basis for granting the waiver request for
ethanol-gasoline blends containing up to 15 vol% ethanol had been met.
(See 74 FR 18228).
---------------------------------------------------------------------------
\9\ Since E15 has greater than 2.7 wt% oxygen content, E15 needs
a waiver under CAA section 211(f)(4).
---------------------------------------------------------------------------
In a separate action today, EPA waived the prohibition in CAA
section 211(f)(1) to allow introduction into commerce of E15 for use in
MY2007 and newer light-duty motor vehicles, including passenger cars,
light-duty trucks and medium duty passenger vehicles (hereafter light-
duty motor vehicles). EPA is deferring a decision concerning MY2001-
2006 light-duty motor vehicles, and has denied the waiver for all other
motor vehicles.\10\ EPA's partial waiver decision is based on a
determination that E15 will not cause or contribute to a failure of
MY2007 and newer light-duty motor vehicles to achieve compliance with
the emissions standards to which they were certified under section 206
of the CAA over their useful lives. EPA is still evaluating the effect
of E15 on MY2001-2006 light-duty motor vehicles to determine whether a
waiver of CAA section 211(f)(1) is appropriate for use of E15 in those
motor vehicles. EPA also decided that it could not make such a
determination and therefore was denying the waiver for all other motor
vehicles, including MY2000 and older light-duty motor vehicles. EPA
requests comment and additional information regarding the use of E15 in
MY 2000 and older motor vehicles.
---------------------------------------------------------------------------
\10\ See Partial Grant and Partial Denial of Clean Air Act
Waiver Application Submitted by Growth Energy to Increase the
Allowable Ethanol Content of Gasoline to 15 Percent; Decision of the
Administrator elsewhere in this issue of the Federal Register.
---------------------------------------------------------------------------
EPA issued the partial waiver with several conditions, some of
which would be fulfilled by the safeguards being proposed today. The
conditions apply to the upstream parties subject to the waiver
(refiners, producers of ethanol and oxygenate blenders that introduce
E15 into commerce), and are designed to ensure that when E15 is
introduced into commerce, it will only be used in the appropriate
light-duty motor vehicles. Some of the conditions call for the ethanol
blenders, fuel manufacturers, and fuel additive manufacturers (ethanol
producers) to take various actions to control the distribution and use
of their product so that E15 is only used in approved motor vehicles.
The partial waiver imposes different conditions on the different
parties. Ethanol blenders, fuel manufacturers, and ethanol producers
that introduce E15 into commerce are all responsible for making sure
that appropriate labeling occurs on fuel pumps to mitigate potential
misfueling. However, this condition, in particular, may be difficult
for these parties to satisfy given their limited control over actions
taken at retail, which, as discussed below, prompted today's proposal
for fuel pump labels. All three parties are also responsible for
conducting fuel pump labeling surveys to ensure that pumps are properly
labeled and that the correct ethanol blends are loaded into the
appropriate tanks at retail stations. Ethanol blenders and fuel
manufacturers must also use PTDs to properly document information
regarding the ethanol blends to help ensure proper blending and
distribution.
In June 2010 EPA received a request from ADM to consider, within
the context of the E15 waiver application, a waiver for E12 for all
motor vehicles.\11\ As discussed in the E15 waiver decision document,
EPA concluded that there was insufficient basis to support such a
waiver for motor vehicles or nonroad products beyond the MY2007 and
newer model year light-duty motor vehicles for which the E15 waiver was
being granted.

---------------------------------------------------------------------------
C. Reasons for the Proposed Actions in This Rulemaking
The proposed rules would directly prohibit or control the
distribution and use of E15. The rules would apply to parties such as
retail stations that are not directly subject to the conditions on the
waiver. Collectively, these provisions would mitigate misfueling and
maximize the likelihood that E15 is only used in approved motor
vehicles. This would also promote the successful introduction of E15
into commerce. The specific provisions are discussed in detail in
Sections III-V.
In this action, the Agency is proposing to use its authority to
help minimize the potential for emissions increases associated with
misfueling with E15. Importantly, the proposed safeguards would also
assist the ethanol producers and blenders in carrying out the
conditions of the waiver. EPA realizes that ethanol blenders, fuel
manufacturers, and ethanol producers
[[Page 68049]]
may have difficulty satisfying the conditions outlined in the E15
partial waiver decision, particularly the fuel pump labeling
requirements. Most retail stations are independently owned and
operated, which may make it difficult for the ethanol blenders, fuel
manufacturers, and ethanol producers to ensure that labels are properly
placed on fuel pumps dispensing E15. Under CAA section 211(f)(4), EPA
is limited in what kind of conditions it can place on a waiver decision
and on whom those conditions may be placed. For example, EPA placed the
partial waiver conditions on the ethanol blenders, fuel manufacturers,
and ethanol producers, the parties subject to the prohibition in
section 211(f)(1), and not on the retail stations. This makes it
difficult to ensure effective or complete pump labeling and misfueling
mitigation. Without Agency action that requires the provisions proposed
in today's rulemaking (i.e. fuel pump labeling, PTDs, and a national
survey), the conditions contained in the E15 partial waiver decision
would likely make the distribution of E15 impracticable. However, under
CAA section 211(c), EPA has the authority to adopt appropriate controls
or prohibitions on the distribution and sale of fuels and fuel
additives to avoid emissions increases. EPA's proposed use of this
authority would also assist the ethanol blenders, fuel manufacturers,
and ethanol producers in carrying out the conditions of the partial
waiver so the conditions on the E15 partial waiver are properly
implemented. Today's rulemaking also provides EPA with additional tools
for regulatory oversight of the ethanol blenders, fuel manufacturers,
and ethanol producers introducing E15 into commerce.
D. Federalism Implications
As mentioned in Section II.A, the proposed prohibition regarding
use of E15 in MY2000 and older vehicles, heavy-duty gasoline engines
and vehicles, motorcycles, and nonroad engines, vehicles, and equipment
is based on the authority in section 211(c)(1) of the Act, as well as
our recordkeeping and information collection authority under sections
208 and 114. Section 211(c)(4)(A) of the CAA provides that no State or
political subdivision thereof may prescribe or attempt to enforce ``for
purposes of motor vehicle emission control'' any control or prohibition
``respecting any characteristic or component of a fuel or fuel
additive'' in a motor vehicle or motor vehicle engine if EPA has
prescribed a control or prohibition applicable to such characteristic
or component of the fuel or fuel additive under section 211(c)(1). This
prohibition applies to all States except California, as provided in
section 211(c)(4)(B). Also, section 211(c)(4)(A) applies only to
controls or prohibitions respecting any characteristics or components
of fuels or fuel additives for motor vehicles or motor vehicle engines,
that is, highway vehicles. Therefore, a State control or prohibition
would be preempted under section 211(c)(4)(A), only if it is ``for the
purposes of motor vehicle emission control.'' Further, even if a State
rule is established for purposes of motor vehicle emission control, it
will not be preempted under section 211(c)(4)(A) unless it is for the
same ``characteristic or component of a fuel or fuel additive in a
motor vehicle or motor vehicle engine'' for which EPA has prescribed a
control or prohibition under section 211(c)(1)(A). Today's action
proposes a rule that would limit the ethanol content in fuel used in
certain vehicles and engines as well as proposes misfueling mitigation
measures to effectuate that limitation.
The Agency is not aware of any State rules or laws that would be
preempted by today's proposed rule if adopted. States have not
controlled ethanol volumes in gasoline for purposes of motor vehicle
emission control. Also, our rule would not require States to change
their existing labels. The rule as proposed would impose no substantial
direct costs, nor would it have any substantial direct effects on State
or local governments. EPA requests comments on the issue of preemption
of State fuel programs.
Further, EPA consulted with State and local officials early in the
process of developing the proposed action to permit them to have
meaningful and timely input into its development. EPA met with members
of the National Association of Clean Air Agencies (NACAA) to discuss
the nature of today's proposed rule. Additionally, we provided State
and local governments an opportunity to provide comment on the
implementation of misfueling mitigation measures for a partial E15
waiver in both the RFS2 NPRM (see 74 FR 25016) and the E15 waiver
request notice (see 74 FR 18228). We received comments from only one
State on this issue in the RFS2 NPRM, and it supported efforts for
properly labeling fuel pumps containing gasoline-ethanol blends.
III. Misfueling Mitigation Measures
As explained above, CAA section 211(c) grants the Agency authority
to control or prohibit the distribution of a fuel or fuel additive when
it will significantly impair emission controls or the emission products
from that fuel will cause or contribute to air pollution that we
reasonably anticipate may endanger public health or welfare. As more
fully discussed in Section VI, we are proposing to prohibit use of E15
in MY2000 and older light-duty motor vehicles, and in all heavy-duty
gasoline engines and vehicles, motorcycles and nonroad products based
on the projected increased emissions that would occur from using E15 in
those motor vehicles and nonroad products. We are also proposing to
prohibit gasoline retail stations and wholesale purchaser-consumer
facilities from selling E15 for use in these products if pumps at those
locations are not properly labeled. Since the Agency is deferring a
decision for MY2001-2006 light-duty motor vehicles, we are not
proposing a prohibition for fuel used in these motor vehicles at this
time. DOE testing of MY2001-2006 light-duty motor vehicles is ongoing
and EPA expects to make a waiver determination for these vehicles
shortly after the results of the DOE testing are available. If EPA does
not grant an E15 waiver for MY2001-2006 light-duty motor vehicles, then
we would expect to include the same prohibitions for these MY motor
vehicles in the final rulemaking .\12\
---------------------------------------------------------------------------
\12\ Even though we are not proposing an actual prohibition for
motor vehicles MY2001-2006, it is still unlawful to use E15 in these
motor vehicles until an E15 waiver is granted for these motor
vehicles.
---------------------------------------------------------------------------
EPA is proposing a misfueling mitigation strategy to effectuate
those proposed prohibitions and to more generally limit the use of E15
to MY2007 and newer light-duty motor vehicles as approved today in the
E15 partial waiver decision. We believe that there are four important
components to an effective misfueling mitigation strategy for reducing
the potential for misfueling with E15. First, effective labeling is a
key factor. Labeling is needed to inform consumers of the potential
impacts of using E15 in vehicles and engines not approved for its use,
to mitigate the potential for intentional and unintentional misfueling
of these vehicles and engines. Labeling is also done at the point of
sale where the consumer most likely will be choosing which fuel to use.
Second, retail stations and wholesale purchaser-consumers need
assurance regarding the ethanol content of the fuel that they purchase
so they can direct the fuel to the appropriate storage tank and
properly label their fuel pumps. The use of proper
[[Page 68050]]
documentation in the form of PTDs has proven to be an effective means
of both ensuring that retail stations know what fuel they are
purchasing and as a possible defense for retail stations in cases of
liability in the event of a violation of EPA standards. Third, national
labeling and fuel sampling surveys are necessary to ensure that retail
stations are complying with labeling requirements, ethanol blenders are
not blending more than the stated amount of ethanol on PTDs, and
assuring downstream compliance for fuel refiners. The Agency has used
this general strategy to implement several fuel programs over the past
thirty years, including the unleaded gasoline program, the RFG program,
and the diesel sulfur program. EPA solicits comments on all of these
provisions as more fully described below.
The fourth component of an effective misfueling mitigation strategy
is effective public outreach and consumer education. Outreach to
consumers and stakeholders is critical to mitigate misfueling incidents
that can result in increased emissions and vehicle or engine damage.
Consumers will need to be engaged through a variety of media to ensure
that accurate information is conveyed to the owners and operators of
vehicles and engines.
The misfueling mitigation program proposed today generally mirrors
the misfueling conditions in today's partial waiver decision. While the
waiver provides an opportunity for a fuel or fuel additive manufacturer
to meet the conditions, the Agency believes that the proposed the
measures would provide the most practical method of meeting the
purposes of and satisfying the conditions of today's partial waiver
decision.
A. Labeling Requirements
Today's rule proposes to require that retailers and wholesale
purchaser-consumers who choose to sell or dispense E15 must label any
dispensers of this gasoline-ethanol blend. We are also seeking comment
on requiring that dispensers of other gasoline-ethanol blends that
contain 10 vol% ethanol or less to be labeled at such time as a retail
station chooses to dispense E15 to help alleviate any confusion to
consumers. Additionally, we seek comment on requiring labels for E85
pumps and blender pumps.
1. E15 Labels
We are proposing requirements that gasoline pumps dispensing E15 be
labeled. The label would have to indicate that the fuel contains up to
15 vol% ethanol--that is, the fuel is a gasoline-ethanol blend that
contains greater than 10 vol% ethanol but not more than 15 vol%
ethanol. Retailers and wholesale purchaser-consumers who choose to sell
E15 would be required to label pumps dispensing E15, clearly indicating
that the fuel should not be used in MY2000 and older motor vehicles,
motorcycles, heavy-duty gasoline engines and vehicles, or any nonroad
products. However, EPA also proposes that the label would be modified
if the E15 waiver is extended to earlier model year vehicles and/or
nonroad products.
Based on the Agency's experience with fuel pump labeling for Ultra-
Low Sulfur Diesel (ULSD) and Low Sulfur Diesel (LSD) (see 40 CFR
80.570), there are four important elements to an effective label for
misfueling. The Agency proposes that the language of the E15 label
would have four components: (1) An information component; (2) a legal
approval component; (3) a technical warning component; and (4) a legal
warning component. Together, these four components highlight the
critical information necessary to inform consumers about the impacts of
using E15.
a. Information Component
The first component informs consumers of the maximum ethanol
content the fuel may contain. For E15, the Agency proposes that the
information component of the label should contain two aspects, both an
acronym for the fuel (in this case E15) and a description of what the
acronym means (in this case informing consumers that the fuel may
consist of a range of ethanol up to a maximum of 15 vol% ethanol by
volume). We propose that this component of the label read:
This fuel contains 15% ethanol maximum
We propose that this label be applied to any fuel dispenser with
greater than 10% ethanol but not more than 15 vol% ethanol. Thus, in
the case of any mid-grade fuel that might be blended from E10 and E15,
it would also be required to have the E15 label.
b. Legal Approval Component
The second component of the label language would include
information that informs consumers of what vehicles and engines are
approved to use E15, mirroring EPA's decisions taken in the waiver
context. Since EPA granted a partial waiver of E15 limiting its legal
use to MY2007 and later light-duty motor vehicles, its use is only
permitted in these motor vehicles. Based on the partial waiver, the
Agency proposes that this portion of the label read as follows:
Use only in:
2007 and newer gasoline cars
2007 and newer light-duty trucks
Flex-fuel vehicles.
As discussed elsewhere in today's proposal, if EPA decides to include
more model years in a subsequent waiver decision based on the findings
of the testing program, then the model year distinction on the label
would also need to be adjusted accordingly. We anticipate this will
occur before this rulemaking is finalized, and we will make that
adjustment in the final rule. Therefore, the proposed language could
read as follows:
Use only in:
2001 and newer gasoline cars
2001 and newer light-duty trucks
Flex-fuel vehicles.
c. Technical Warning Component
The third component of the label language would alert consumers
that use of E15 in other engines, vehicles, and equipment might cause
damage to these products. Our experience with past labeling provisions
supports the need for both the legal and technical warning so that
consumers are informed of the reason for the prohibition. As discussed
more fully in Section VI, it appears that use of E15 in these
particular products may not only lead to increased emissions but also
has the potential, even if limited in nature, to lead to damage of
motor vehicle and nonroad product components. Without this component to
the label, consumers may more likely be tempted to misfuel--
particularly if the price in the marketplace for E15 is lower than E10.
Therefore, EPA proposes the following language: ``This fuel might
damage other vehicles or engines.''
d. Legal Warning Component
The fourth component of the label would inform consumers that using
E15 in a vehicle or engine not approved for E15 use violates Federal
law. This is similar to the approach used to mitigate the use of LSD in
2007 and newer on-highway diesel engines. Based on that experience, EPA
believes that explicitly notifying consumers that E15 is prohibited by
Federal law for use in MY2000 and older motor vehicles, heavy-duty
gasoline engines and vehicles, on and off-highway motorcycles, and all
nonroad products will result in consumers being less likely to misfuel.
Based on the language currently used on the LSD label (see 40 CFR
80.570), the Agency proposes that the label read
[[Page 68051]]
as follows: ``Federal law prohibits its use in other vehicles and
engines.''
The Agency has traditionally had ``WARNING'' language appear before
the legal warning component to better draw consumers' attention to the
prohibition of using a fuel in certain vehicles and engines (e.g. LSD
in 2007 and newer highway diesel vehicles). After consultation with
stakeholders, it was suggested that the Agency should both change
``WARNING'' to ``CAUTION!'' and place this language at the top of the
label. This would draw consumer attention to the label and help
mitigate both intentional and unintentional misfueling. Therefore, we
propose to have the word ``CAUTION!'' appear at the top of the label
before the information component. The Agency also considered the use of
the word ``ATTENTION'' instead of ``WARNING'' or ``CAUTION.'' We
specifically seek comment on using the term ``CAUTION!'' versus
``WARNING'' or ``ATTENTION''. In addition, the Agency is also
interested in whether using ``STOP'', with or without including a
depiction of a stop sign, would be an appropriate way to draw
consumers' attention to the label. We seek comment on whether there are
other words that would better convey the message to consumers.
e. E15 Label Proposal
Taken together, the Agency proposes the following E15 label:
[GRAPHIC] [TIFF OMITTED] TP04NO10.000
EPA seeks comment on all aspects of the label language. For
example, we seek comment on whether any additional label language
should be required or whether any language should be removed. In
particular, we seek comment on ways to portray the information in ways
that are the most concise and meaningful to consumers. EPA proposes
that the pump labels for E15 be required to be placed on pumps that
will dispense E15 prior to any commercial sale of E15.
One issue that arose from the labeling provisions of the diesel
sulfur program was that the diesel sulfur labeling provisions were
written in a way that allowed flexibility in color and design, causing
retailers difficulty with coming up with a suitable design that
satisfied EPA labeling requirements at the least possible cost. To help
address this issue, stakeholders met with EPA to discuss standardized
label designs that would both satisfy EPA diesel sulfur requirements
and make it easier for retail stations to procure labels. Labeling
templates were designed and made available to retail stations to use.
Based on this experience, we are proposing more explicit specifications
for the E15 label, covering not only the content, but also the
appearance of the E15 pump label.
In today's rulemaking, we are proposing similar appearance and
placement requirements for the E15 labels that were required for the
diesel sulfur program labels. We propose that the titles of the labels
(e.g., E15) must be 24-point, white, bold Arial font, the ``CAUTION!''
text should also be red, uppercase 16-point bold type, the text in the
labels which describes the ethanol content of the fuel must be 20-point
type and that all other required language in the labels must be 14-
point black, Arial font. We propose that the word ``prohibits'' be in
14 point, black, bold, italic, Arial font. All text should be centered
with the arrangement and spacing of the text consistent with the
illustration. We further propose that the label be 3.625'' width by
3.125'' height and that the background for the area which includes
``CAUTION!'', the title (i.e. ``E15''), and the ethanol content (i.e.,
``15% Ethanol Maximum) shall be 1-inch wide and neon-orange in color,
except that a rectangular white background large enough to encompass
``CAUTION!'' shall be superimposed on this neon-orange background.
While we believe it is important to propose these specific label
appearance requirements to aid in consumer recognition and avoid
unnecessary burden on retailers in developing their own designs, we
also recognize that there is a great deal of variation in the design of
fuel pumps and dispensers throughout the nation. Consequently, we not
only seek comment on all visual aspects of our proposed label, but also
suggest that if changes are deemed necessary, regulated and other
interested parties work together to provide us with a consensus
recommendation in their comments, if possible.
In addition to content and appearance, the placement of the label
on the pump is also of concern given the limited space available on the
fuel pump itself. In the diesel sulfur program
[[Page 68052]]
we required that labels must be placed on the vertical surface of each
pump housing and on each side that has gallon and price meters and that
labels be on the upper two-thirds of the pump in a location where they
are clearly visible (see 40 CFR 80.570(d)). We propose the same
placement requirements for the E15 labels. However, since most States
require labels for gasoline blended with ethanol and the Federal Trade
Commission (FTC) requires labels specifying minimum octane levels
across grades of gasoline, the addition of the proposed E15 label may
impact placement of other labels required by State or Federal law.
Furthermore, FTC has proposed a mid-level ethanol gasoline-blend label
(described below) in addition to its octane label which may further
confuse consumers and make E15 label placement difficult. The Agency
seeks comment on the proposed placement of the E15 label in order to
most effectively mitigate misfueling, while at the same time avoid
interference with other labels on the pumps.
2. Additional Fuel Pump Labeling Requirements
In addition to the E15 label proposed above, the Agency is seeking
comment on three additional fuel pump labels that would provide
consistent labeling across all gasoline fuel pumps. First, the Agency
seeks comment on requiring a label on gasoline dispensing fuel pumps
that are dispensing fuels which contain ethanol in concentrations up to
10 vol% (``E10 label'').\13\ We further seek comment on whether E10
labels should be required at a retail station only if and when E15 is
made available for sale at a particular retail station. Such an E10
label would have similar appearance and location requirements to the
E15 label and the required label language would follow a similar form
to that of the E15 label so as to standardize labels for consumers.
---------------------------------------------------------------------------
\13\ If the fuel contains no ethanol, it could be labeled as
such.
---------------------------------------------------------------------------
The purpose of such a label would be to enhance the effectiveness
of the E15 label to protect against consumer misfueling and the
associated emissions impacts. Without such labels, consumers may be
confused regarding whether an unlabeled pump was appropriate for their
vehicle or engine, undercutting the effectiveness and confidence in the
E15 label. This approach is consistent with the labeling requirements
we used in the diesel sulfur program where we required the use of
labels specifying which type of diesel fuel (low-sulfur diesel, ultra-
low sulfur diesel, etc.) was being dispensed from each pump dispensing
diesel fuel.
However, since increasing the number of labels will increase the
total cost to retail stations by requiring that all gasoline dispensing
fuel pumps at a station be labeled, we seek comment on the
appropriateness of such a requirement. The Agency seeks comment on the
following E10 label language:
E10
(Contains up to 10% Ethanol)
For use in all gasoline vehicles and engines.
The Agency also seeks comment on requiring a label on pumps
distributing E85 fuel. E85 is fuel that contains up to 85 vol% ethanol
and at least 15 vol% gasoline, used by flex fuel vehicles (FFVs).\14\
As we noted in the RFS2 NPRM, fuel retailers expressed concern that if
E85 were priced low enough to encourage FFV owners to fuel on it more
frequently, then owners of non-FFVs would also be enticed to misfuel on
it (see 74 FR 24977). This could cause the vehicles and equipment to
operate very poorly, increasing emissions, as well as cause potential
long-term damage and long-term emissions increases. We believe that in
most cases fuel pump labels warning that the use of E85 in non-flex
fuel vehicles is illegal, can damage the vehicle, and can void vehicle
manufacturer warranties may be a sufficient disincentive to mitigate
intentional misfueling. Non-FFVs and nonroad products were not designed
for operation on E85 and may experience serious emissions increases,
operability, and driveability issues, particularly with prolonged use
(e.g. accelerated catalyst deterioration, fuel system component
failures, etc.).
---------------------------------------------------------------------------
\14\ FFVs are vehicles or engines that are designed to run on
gasoline or gasoline-ethanol blends up to E85.
---------------------------------------------------------------------------
Such an E85 label would have similar appearance and location
requirements to the E15 label (discussed above) and the required label
language would follow a similar form to that of the E15 label. The
Agency seeks comment on the following E85 label language:
E85
(Contains up to 85% Ethanol)
For use in flex-fuel vehicles only.
WARNING
Federal law prohibits use in all other vehicles and engines.
May damage these vehicles and engines.
We request comment on whether the proposed labeling requirements would
provide sufficient warning to consumers not to refuel non-flex-fuel
vehicles with E85. Additionally the Agency seeks comment on the label
language for the E85 label.
The Agency also seeks comment on requiring labels for so-called
blender pumps. Blender pumps allow station owners to blend E85 and
gasoline in their storage tanks to create intermediate gasoline-ethanol
blends. This allows either station owners or potentially FFV drivers to
choose which gasoline-ethanol blend they prefer, based on operating
characteristics and price. During both the RFS2 and E15 waiver request
comment periods, the
