Approval and Promulgation of Air Quality Implementation Plans;
Maine; Approval of Fuel Control Program under Section 211(c)
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: EPA is approving a State Implementation Plan (SIP) revision
submitted by the State of Maine on March 10, 1999, establishing a lower
Reid Vapor Pressure (RVP) fuel requirement for gasoline distributed in
southern Maine which includes York, Cumberland, Sagadahoc, Kennebec,
Androscoggin, Knox, and Lincoln Counties. Maine has developed these
fuel requirements to reduce emissions of volatile organic compounds
(VOC) in accordance with the requirements of the Clean Air Act (CAA).
EPA is approving Maine's fuel requirements into the Maine SIP because
EPA has found that the requirements are necessary for southern Maine to
achieve the national ambient air quality standard (NAAQS) for ozone.
DATES: This direct final rule is effective on July 13, 1999 without
further notice, unless EPA receives adverse comment by June 14, 1999.
If adverse comment is received, EPA will publish a timely withdrawal of
the direct final rule in the Federal Register and inform the public
that the rule will not take effect.

SUPPLEMENTARY INFORMATION:
I. Background
Under the Clean Air Act Amendments of 1990, southern Maine was
divided into three separate ozone nonattainment areas: the Portland
area which is comprised of York, Cumberland and Sagadahoc Counties; the
Lewiston-Auburn area which is comprised of Androscoggin and Kennebec
counties; and the Knox and Lincoln County area. Each of these areas was
classified as moderate nonattainment for ozone. The ozone attainment
deadline for these areas was initially November 15, 1996. Just downwind
from these areas, the largely rural counties of Hancock and Waldo were
designated nonattainment and classified as marginal.
To bring these areas into attainment, the State has adopted and
implemented a broad range of ozone control measures including stage II
vapor recovery on larger facilities, numerous stationary and area
source VOC controls, an inspection and maintenance (I/M) program, and
the California low emission vehicle program. In addition, the State
participated in the federal reformulated gasoline (RFG) program from
January 1, 1995 until March 10, 1999 in southern Maine. These measures
resulted in significant air quality improvements in southern Maine.
Following adoption of the new ozone NAAQS (described below), EPA
has determined that the 1-hour ozone standard no longer applies in
certain
[[Page 26307]]
areas of the country that were meeting the 1-hour ozone NAAQS (63 FR
31014, 63 FR 39432). In Maine, EPA made this determination for all
areas outside the Portland area (63 FR 31014). On December 17, 1998,
EPA proposed to make this determination for the Portland area (63 FR
69598).
On July 18, 1997, EPA adopted a new 8-hour ozone standard (62 FR
38856). The new standard defines the new ozone air quality standard
which all areas must meet to protect the public health. EPA is required
to determine the attainment status of areas with respect to the new
standard by July 18, 2000. Current monitoring data for Cumberland,
Sagadahoc, York and Hancock counties indicate that these areas are not
attaining the 8-hour ozone standard. Thus, despite significant progress
toward attaining the 1-hour standard, EPA believes that additional
reductions of ozone precursors will be required for these areas to meet
the new standard.
On October 13, 1998, Maine's Governor requested that EPA allow the
State to discontinue its participation in the federal RFG program, in
accordance with the ``opt-out'' procedures set forth in 40 CFR 80.72.
At the same time, the Governor committed to ensure that the State adopt
a control program which achieved VOC reductions equivalent to those
required under the RFG program, specifically identifying fuel controls
as the primary replacement options. EPA approved the Governor's opt-out
request effective March 10, 1999.
On February 24, 1999, the Maine Board of Environmental Protection
(BEP), after a public hearing and comment period, adopted a low-RVP
gasoline rule that set limits on the RVP of gasoline sold during the
summer months in these seven counties in southern Maine. The rule
establishes a phased approach with an ultimate RVP standard of 7.2
pounds per square inch (psi). Specifically, the rule provides that,
beginning May 1, 1999 through September 15, 1999, regulated gasoline
must have an RVP no greater than 7.8 psi. Beginning May 1, 2000 through
September 15, 2000, and each May 1 through September 15 thereafter, no
gasoline may be sold with an RVP greater than 7.2 psi. The State's low-
RVP rule is codified in Chapter 119 of the Maine Department of
Environmental Protection's regulations, entitled ``Motor Vehicle Fuel
Volatility Limit.''
The Department of Environmental Protection, on behalf of the BEP,
submitted its low-RVP rule to EPA as a revision to the SIP on March 10,
1999, the effective date of Maine's ``opt-out'' of the RFG program. On
April 8, 1999, Maine submitted additional technical support for the SIP
revision, including materials supporting the State's request to waive
Clean Air Act preemption of state fuel controls pursuant to section
211(c)(4) of the Act.
By this low-RVP rule, Maine is ensuring that it replaces the VOC
benefits that RFG had been required to achieve. These emission
reductions were critical to Maine's attainment of the 1-hour ozone
standard in several areas. Further, given currently available
monitoring data demonstrating that some of these areas are not meeting
the new 8-hour ozone standard, EPA believes that these reductions will
help achieve that standard.
II. Reid Vapor Pressure
Reid Vapor Pressure is a measure of a gasoline's volatility at a
certain temperature and is a measurement of the rate at which gasoline
evaporates and emits VOC; the lower the RVP, the lower the rate of
evaporation. The RVP of gasoline can be lowered by reducing the amount
of its volatile components, such as butane. Lowering RVP in the summer
months can offset the effect of summer temperature upon the volatility
of gasoline, which, in turn, lowers emissions of VOC. Because VOC is a
necessary component in the production of ground level ozone in
hotsummer months, reduction of RVP will help areas achieve the NAAQS
for ozone and thereby produce benefits for human health and the
environment.
The primary emission benefits from low-RVP gasoline come from
reductions in VOC evaporative emissions; exhaust emission reductions
are much smaller. Because oxides of nitrogen (NOX) are a
product of combustion, they will not be found in evaporative emissions,
and low-RVP gasoline will have little or no effect on NOX.
III. State Submittal
The fuel program for southern Maine covering York, Cumberland,
Sagadahoc, Kennebec, Androscoggin, Knox, and Lincoln Counties
establishes limits on gasoline properties that reduce emissions of VOC.
The rule controls the RVP of gasoline sold in this area in two steps.
Beginning May 1, 1999 through September 15, 1999, the gasoline sold
must have an RVP no greater than 7.8 psi, and from May 1, 2000 through
September 15, 2000, and each May 1 through September 15 thereafter, no
gasoline may be sold with an RVP greater than 7.2 psi. These same
counties in Maine had previously participated in the federal RFG
program.
IV. Clean Air Act Requirements
In determining the approvability of a SIP revision, EPA must
evaluate the proposed revision for consistency with the requirements of
the CAA and EPA regulations, as found in section 110 and part D of the
CAA and 40 CFR part 51 (Requirements for Preparation, Adoption, and
Submittal of Implementation Plans).
For SIP revisions addressing certain fuel measures, an additional
statutory requirement applies. CAA section 211(c)(4)(A) prohibits state
regulations respecting a fuel characteristic or component for which EPA
has adopted a control or prohibition under section 211(c)(1), unless
the state control is identical to the federal control. Section
211(c)(4)(C) provides an exception to this preemption if EPA approves
the state requirements in a SIP. Section 211(c)(4)(C) states that the
Administrator may approve preempted state fuel standards in a SIP:
only if [s]he finds that the State control or prohibition is
necessary to achieve the national primary or secondary ambient air
quality standard which the plan implements. The Administrator may
find that a State control or prohibition is necessary to achieve
that standard if no other measures that would bring about timely
attainment exist, or if other measures exist and are technically
possible to implement, but are unreasonable or impracticable.
EPA's August, 1997 ``Guidance on Use of Opt-in to RFG and Low RVP
Requirements in Ozone SIPS'' gives further guidance on what EPA is
likely to consider in making a finding of necessity.
V. EPA Evaluation
A. General SIP Requirements
As discussed below, EPA has evaluated the submitted SIP revision
and has determined that it is consistent with the requirements of the
CAA and EPA regulations. EPA has found that the March 10, 1999, SIP
revision, as supplemented by the additional technical support submitted
on April 8, 1999, conforms to EPA's completeness criteria in 40 CFR
part 51, appendix V.
The SIP submittal contains: (1) Chapter 119, Maine Department of
Environmental Protection regulations, as adopted by the Maine Board of
Environmental Protection on February 24, 1999 and effective on March 9,
1999; (2) documentation of the public notice dated December 22, 1998,
and a transcript of the public hearing regarding the amendment of
Chapter 119, dated January 20, 1999; (3) evidence of State legal
authority; and (4) application for waiver of federal
[[Page 26308]]
preemption. Information regarding prohibitions on the sale of non-
conforming gasoline, test procedures and sampling for the SIP revision
can be found in Chapter 119 of the Maine Department of Environmental
Protection regulations, and Maine statutes on enforcement and penalties
can be found at Title 38 of Maine Revised Statutes Annotated (M.R.S.A.)
Sections 348 and 349. EPA has concluded that these provisions confer on
the State the requisite authority to enforce compliance with the 7.2
psi (and initial 7.8 psi) RVP limit.
B. Section 211(c)(4)(C)
1. Federal Preemption
CAA section 211(c)(4)(A) preempts certain state fuel regulations by
prohibiting a state from prescribing or attempting to enforce any
control or prohibition respecting any characteristic or component of a
fuel or fuel additive for the purposes of motor vehicle emission
control if theAdministrator has prescribed under section 211(c)(1) a
control or prohibition applicable to such characteristic or component
of the fuel or fuel additive, unless the state prohibition is identical
to the prohibition or control prescribed by the Administrator.
EPA first proposed to regulate summertime gasoline RVP pursuant to
211(c)(1) of the Act in 1987 (52 FR 31274). EPA's gasoline RVP proposal
resulted in a two-phased final regulation that Congress incorporated
into the CAA at section 211(h). Phase I of the regulation took effect
in 1990 (54 FR 11868) for the years 1990 and 1991. Phase II of the
regulation became effective in 1992 (55 FR 23658). These regulations
are found in 40 CFR 80.27. Under the regulations, the continental
United States is divided into two control regions, Class B and Class C.
Generally speaking, the Class B states are the warmer southern and
western states, and Class C states are the cooler northern states. The
Phase II regulation limits the volatility of gasoline sold during the
high ozone season to 9.0 psi RVP for Class C areas and 7.8 psi RVP for
Class B ozone nonattainment areas. Maine is a Class C state and is
therefore required under the federal rule to meet the 9.0 psi RVP
standard. See 40 CFR 80.27(a)(2).
Because Maine's fuel requirement for the southern Maine area
limiting summertime RVP to 7.2 psi is not identical to the federal fuel
standards applicable to the fuel characteristic RVP (i.e., federal
phase II volatility limit of 9.0 psi), Maine's requirement is preempted
unless it is approved into the Maine SIP.
2. Necessity
A state may prescribe and enforce an otherwise preempted low-RVP
requirement only if the EPA approves the control into the state's SIP.
In order to approve a preempted state fuel control into a SIP, EPA must
find that the state control is necessary to achieve a NAAQS. In order
to demonstrate the necessity of a fuel control, the state must show
either that no other measures exist to bring about timely attainment,
or that such measures, while technically possible, are unreasonable or
impracticable. Thus, to determine whether Maine's low-RVP rule is
necessary to meet the ozone NAAQS, EPA must consider whether there are
other reasonable and practicable measures available to produce the
needed emission reductions for ozone control.
With the State's decision to opt-out of the federal RFG program,
additional VOC reductions are necessary to ensure that the Portland
area continues to meet the 1-hour ozone standard and to help the entire
area achieve the new 8-hour ozone standard. The Portland area has
measured air quality meeting the 1-hour standard by a slim margin
(i.e., the design value for the area was 0.124 ppm, just below the
0.125 ppm standard). Given the narrow margin of attainment, it is clear
that the VOC reductions provided by participation of the seven counties
of southern Maine in the federal RFG program were critical to the
Portland area's achievement of the ozone NAAQS.
For purposes of demonstrating necessity, EPA has used the VOC
reductions provided by RFG as an estimate of the emission reductions
that are necessary for southern Maine to achieve the ozone NAAQS. EPA
believes this estimate of necessary reductions is conservative in that
it is based on the reductions needed for attainment of the 1-hour ozone
standard rather than the reduction needed for the new 8-hour standard.
Current monitoring data in Cumberland, Hancock, York and Sagadahoc
counties suggest that additional reductions will be necessary for the
state to achieve the new 8-hour standard.
In its 15-percent rate of progress plan for the Portland area,
Maine had estimated that RFG would achieve 6.96 tons of VOC reduction
per summer day. This figure was calculated using only vehicle miles
traveled in the three-county Portland area. The sale of RFG in the
surrounding four counties further benefitted the Portland area due to
driving patterns into and around the Portland area and the geographic
proximity of these surrounding counties.
With this estimate of the VOC reductions necessary to achieve the
ozone NAAQS, the State evaluated an extensive list of non-fuel
alternative controls to determine if reasonable and practicable
controls could be implemented to provide sufficient VOC reductions in a
timely manner. The State analyzed potential control measures by
reviewing previously prepared emission inventories to determine if
other non-fuel control measures could be adopted, and used to replace
the VOC reductions that RFG had achieved. They reviewed all the source
categories that comprised the emission inventory, and evaluated control
measures on each source category. For a variety of reasons, most
control measures were either already implemented, or were found to be
unreasonable or impracticable for achieving reductions in advance of
the 1999 and/or 2000 ozone season.
As one example, the State evaluated the possibility of further
controlling gasoline refueling, or ``stage II,'' emissions. The State
does have a stage II program for larger facilities, but expanding the
geographic coverage, and requiring smaller facilities (i.e., gas
stations) to comply would yield among the most additional VOC
reductions of any control strategy that the State reviewed. The State
concluded that first, a legislative change, as well as a regulatory
change, would be necessary to further control emissions from this
source category. Further, the actual installation of these controls
would take a number of additional months, which would be beyond the
time frame that Maine needed to secure the emission reductions. For
these reasons, the State concluded that further stage II controls were
not a practical measure for achieving VOC emission reductions in
advance of the summer of 1999. EPA believes implementation of such
controls would be difficult and impractical to achieve these reductions
even by the summer of 2000. Other control measures were similarly
evaluated, and determined to be either technically impossible or
unreasonable and impracticable.
The State's analysis identified several non-fuel alternative
controls that could conceivably be implemented by the summer of 2000
the time frame for complete adoption of the phased low-RVP standard. At
best, adoption of all available measures would result in about 4.5 tons
per day (tpd) reduction (assuming stage II could be
[[Page 26309]]
implemented) which is 2.46 tpd less than the estimated necessary VOC
reductions. Thus, even with implementation of all reasonable and
practicable non-fuel control measures, additional VOC reductions are
necessary.
Maine's low-RVP rule will achieve approximately 7 tpd of VOC
reductions once fully implemented beginning the summer of 2000 (based
on vehicle miles traveled in the Portland area). Due to the driving
patterns and proximity of the surrounding four counties, EPA believes
RVP controls in these areas will further benefit the Portland area. EPA
believes these emission reductions are necessary to achieve the
applicable ozone NAAQS in southern Maine. EPA is basing today's action
on the information available to the Agency at this time, which
indicates that adequate reasonable and practicable non-fuel measures
are not available to the State that would achieve these needed emission
reductions, and protect Maine's air quality in a timely manner. Hence,
EPA is finding that the RVP standards are necessary for attainment of
the applicable ozone NAAQS, and EPA is approving them as a revision to
the Maine SIP.
Final Action
EPA has evaluated the submitted SIP revision and has determined
that it is consistent with the CAA and EPA regulations. EPA has also
found that this two-step low-RVP fuel control measure is necessary to
achieve the ozone NAAQS in southern Maine pursuant to the CAA.
Therefore, EPA is approving the Maine low-RVP rule as submitted on
March 10, 1999 into the Maine SIP.
EPA is publishing this action without prior proposal because the
Agency views this as a noncontroversial amendment and anticipates no
adverse comments. Further, the State has requested approval of this
action in advance of this summer season. However, in the proposed rules
section of this Federal Register publication, EPA is publishing a
separate document that will serve as the proposal to approve the SIP
revision should relevant adverse comments be filed. This rule will be
effective July 13, 1999 without further notice unless the Agency
receives relevant adverse comments by June 14, 1999.
If EPA receives such comments, then EPA will publish a notice
withdrawing the final rule and informing the public that the rule will
not take effect. All public comments received will then be addressed in
a subsequent final rule based on the proposed rule. EPA will not
institute a second comment period on the proposed rule. All parties
interested in commenting on this action should do so at this time. If
no such comments are received, the public is advised that this rule
will be effective on July 13, 1999 and no further action will be taken
on the proposed rule.
Nothing in this action should be construed as permitting or
allowing or establishing a precedent for any future request for
revision to any State implementation plan. Each request for revision to
the State implementation plan shall be considered separately in light
of specific technical, economic, and environmental factors and in
relation to relevant statutory and regulatory requirements.
VI. Administrative Requirements
A. Executive Order 12866
The Office of Management and Budget (OMB) has exempted this
regulatory action from Executive Order (E.O.) 12866, entitled
``Regulatory Planning and Review.''
B. Executive Order 12875
Under E.O. 12875, EPA may not issue a regulation that is not
required by statute and that creates a mandate upon a state, local, or
tribal government, unless the Federal government provides the funds
necessary to pay the direct compliance costs incurred by those
governments, or EPA consults with those governments. If EPA complies by
consulting, Executive Order 12875 requires EPA to provide to the Office
of Management and Budget, a description of the extent of EPA's prior
consultation with representatives of affected state, local, and tribal
governments, the nature of their concerns, copies of written
communications from the governments, and a statement supporting the
need to issue the regulation. In addition, E.O. 12875 requires EPA to
develop an effective process permitting elected officials and other
representatives of state, local, and tribal governments ``to provide
meaningful and timely input in the development of regulatory proposals
containing significant unfunded mandates.''
Today's rule does not create a mandate on state, local or tribal
governments that does not already exist as a matter of State law. EPA
is simply approving a state regulation under the Clean Air Act.
Accordingly, the requirements of section 1(a) of E.O. 12875 do not
apply to this rule.
C. Executive Order 13045
Protection of Children from Environmental Health Risks and Safety
Risks (62 FR 19885, April 23, 1997), applies to any rule that: (1) is
determined to be ``economically significant'' as defined under E.O.
12866, and (2) concerns an environmental health or safety risk that EPA
has reason to believe may have a disproportionate effect on children.
If the regulatory action meets both criteria, the Agency must evaluate
the environmental health or safety effects of the planned rule on
children, and explain why the planned regulation is preferable to other
potentially effective and reasonably feasible alternatives considered
by the Agency.
This rule is not subject to E.O. 13045 because it is not
``economically significant'' as defined under E. O. 12866, and does not
involve an action that addresses environmental or safety risks.
D. Executive Order 13084
Under E.O. 13084, EPA may not issue a regulation that is not
required by statute, that significantly uniquely affects the
communities of Indian tribal governments, and that imposes substantial
direct compliance costs on those communities, unless the Federal
government provides the funds necessary to pay the direct compliance
costs incurred by the tribal governments, or EPA consults with those
governments. If EPA complies by consulting, Executive Order 13084
requires EPA to provide to the Office of Management and Budget, in a
separately identified section of the preamble to the rule, a
description of the extent of EPA's prior consultation with
representatives of affected tribal governments, a summary of the nature
of their concerns, and a statement supporting the need to issue the
regulation. In addition, Executive Order 13084 requires EPA to develop
an effective process permitting elected officials and other
representatives of Indian tribal governments ``to provide meaningful
and timely input in the development of regulatory policies on matters
that significantly or uniquely affect their communities.''
Today's rule does not significantly or uniquely affect the
communities of Indian tribal governments. This action does not involve
or impose any requirements that affect Indian Tribes. Accordingly, the
requirements of section 3(b) of E.O. 13084 do not apply to this rule.
E. Regulatory Flexibility Act
The Regulatory Flexibility Act (RFA) generally requires an agency
to conduct a regulatory flexibility analysis of any rule subject to
notice and comment rulemaking requirements unless the
[[Page 26310]]
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 not-for-profit enterprises, and small
governmental jurisdictions. This final rule will not have a significant
impact on a substantial number of small entities because SIP approvals
under section 110 and subchapter I, part D of the Clean Air Act do not
create any new requirements but simply approve requirements that the
State is already imposing. Therefore, because the Federal SIP approval
does not create any new requirements, I certify that this action will
not have a significant economic impact on a substantial number of small
entities. Moreover, due to the nature of the Federal-State relationship
under the Clean Air Act, preparation of flexibility analysis would
constitute Federal inquiry into the economic reasonableness of state
action. The Clean Air Act forbids EPA to base its actions concerning
SIPs on such grounds. Union Electric Co., v. U.S. EPA, 427 U.S. 246,
255-66 (1976); 42 U.S.C. 7410(a)(2).
F. Unfunded Mandates
Under sections 202 of the Unfunded Mandates Reform Act of 1995
(``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA
must prepare a budgetary impact statement to accompany any proposed or
final rule that includes a Federal mandate that may result in estimated
costs to State, local, or tribal governments in the aggregate, or to
the private sector, of $100 million or more. Under section 205, EPA
must select the most cost-effective and least burdensome alternative
that achieves the objectives of the rule and is consistent with
statutory requirements. Section 203 requires EPA to establish a plan
for informing and advising any small governments that may be
significantly or uniquely impacted by the rule.
EPA has determined that this final approval action does not include
a Federal mandate that may result in estimated costs of $100 million or
more to either State, local, or tribal governments in the aggregate, or
to the private sector. This Federal action approves pre-existing
requirements under State or local law, and imposes no new requirements.
Accordingly, no additional costs to State, local, or tribal
governments, or to the private sector, result from this action.
G. Submission to Congress and the Comptroller General
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of the Congress and to the Comptroller General of the
United States. EPA will submit a report containing this rule and other
required information to the U.S. Senate, the U.S. House of
Representatives, and the Comptroller General of the United States prior
to publication of the rule in the Federal Register. This rule is not a
``major rule'' as defined by 5 U.S.C. 804(2).
H. Petitions for Judicial Review
Under section 307(b)(1) of the Clean Air Act, petitions for
judicial review of this action must be filed in the United States Court
of Appeals for the appropriate circuit by July 13, 1999. Filing a
petition for reconsideration by the Administrator of this final rule
does not affect the finality of this rule for the purposes of judicial
review nor does it extend the time within which a petition for judicial
review may be filed, and shall not postpone the effectiveness of such
rule or action. This action may not be challenged later in proceedings
to enforce its requirements. (See section 307(b)(2).) EPA encourages
interested parties to comment in response to the proposed rule rather
than petition for judicial review, unless the objection arises after
the comment period allowed for in the proposal.
