Approval and Promulgation of Air Quality Implementation Plans; 
Ohio; Control of Gasoline Volatility

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: EPA is approving a State Implementation Plan (SIP) revision 
submitted by the State of Ohio on February 14, 2006, and October 6, 
2006, establishing a lower Reid Vapor Pressure (RVP) fuel requirement 
for gasoline distributed in the Cincinnati and Dayton 8-hour ozone 
nonattainment areas. Ohio has developed this fuel requirement to reduce 
emissions of volatile organic compounds (VOC) in accordance with the 
requirements of the Clean Air Act (CAA). EPA is approving Ohio's fuel 
requirement into the Ohio SIP because EPA has found that the 
requirement is necessary for the Cincinnati and Dayton areas to achieve 
the 8-hour ozone national ambient air quality standard (NAAQS). This 
action is being taken under section 110 of the CAA. On March 29, 2007, 
the EPA published a Notice of Proposed Rulemaking (NPRM) proposing to 
approve the SIP revision. During the comment period EPA received a 
number of comments both supporting and opposing the approval of the 
fuel requirement.
    This document summarizes the comments received, EPA's responses, 
and finalizes the approval of Ohio's SIP revision to establish a RVP 
limit of 7.8 pounds per square inch (psi) for gasoline sold in the 
Cincinnati and Dayton 8-hour ozone nonattainment areas.

DATES: This final rule is effective on May 31, 2007.

SUPPLEMENTARY INFORMATION: Throughout this document whenever ``we,'' 
``us,'' or ``our'' is used, we mean EPA. This supplementary information 
section is arranged as follows:

I. What is the background for this action?
II. What is our response to comments received on the notice of 
proposed rulemaking?
III. What action is EPA taking?
IV. Statutory and Executive Order Review

I. What is the background for this action?

    On April 15, 2004, the EPA designated 5 counties in the Cincinnati, 
Ohio area (Hamilton, Butler, Clinton, Warren and Clermont counties--
Cincinnati-Hamilton, OH-KY-IN) and 4 counties in the Dayton, Ohio area 
(Clark, Greene, Miami, and Montgomery counties--Dayton-Springfield, OH) 
as nonattainment for the 8-hour ozone standard. Both areas have been 
designated Basic nonattainment with respect to the 8-hour ozone 
standard and they are required to attain the

[[Page 29270]]

standard as expeditiously as practicable, but no later than June 2009.
    As part of the State of Ohio's (Ohio) efforts to bring these areas 
into attainment, the State is adopting and implementing a broad range 
of ozone control measures including control of emissions from auto 
refinishing operations, the reduction of VOC emission from portable 
fuel containers, the adoption of industrial solvent degreasing rules, 
and the implementation of a 7.8 pound per square inch (psi) RVP fuel 
program.
    Ohio originally proposed to replace the State's vehicle inspection 
and maintenance (I/M) program in Cincinnati and Dayton, which was 
discontinued by the State on December 31, 2005, with the requirement to 
supply 7.8 psi RVP gasoline to these areas starting in 2006. However, 
the State modified its original request and asked that EPA act on the 
state's fuel waiver request to allow the use of 7.8 psi RVP gasoline in 
both areas. On February 14, 2006, Ohio submitted the fuel waiver 
request as a SIP revision. The submittal included adopted amended rules 
under Ohio Administrative Code Chapter 3745-72 ``Low Reid Vapor 
Pressure Fuel Requirements'' to require the use of 7.8 psi RVP gasoline 
in the Cincinnati and Dayton areas beginning on June 1, 2006.
    Soon after the State's February 14, 2006 submittal, the American 
Petroleum Institute (API) appealed the State's 7.8 psi RVP rule on the 
basis that there was insufficient time to implement the rule and that 
EPA had not yet issued a waiver under section 211(c)(4)(C) of the CAA, 
as amended. EPA conducted an informal survey of gasoline suppliers and 
determined that there was not enough 7.8 psi RVP gasoline to supply the 
Cincinnati and Dayton nonattainment areas during the 2006 ozone season. 
As part of the State's settlement with API on its appeal, Ohio agreed 
to revise the rule to delay the effective date of the rule until twelve 
months following the approval of a fuel waiver by EPA in order to 
ensure that there is sufficient time for the regulated community to 
prepare for the change.
    On July 10, 2006, the Ohio Environmental Protection Agency (OEPA) 
adopted amended rules under the Ohio Administrative Code Chapter 3745-
72 ``Low Reid Vapor Pressure Fuel Requirements'' to modify the 
implementation date for the required use of 7.8 psi RVP gasoline in the 
Cincinnati and Dayton areas to be one year after the approval of a fuel 
waiver under CAA amendments section 211(c)(4)(C). Public hearings on 
the amended rules were held on June 2, 2006, in Columbus, Ohio and the 
rules became effective at the state level on July 17, 2006.
    The OEPA submitted these amended low-RVP rules to EPA as a revision 
to the SIP on October 6, 2006. As part of the October 6, 2006 
submittal, OEPA included additional technical support for the SIP 
revision, including documentation supporting the State's request to 
waive the CAA preemption of State fuel controls pursuant to section 
211(c)(4) of the CAA.
    On March 29, 2007, EPA proposed approval of the State's SIP 
revision to establish a 7.8 psi low-RVP fuel program in the Cincinnati 
and Dayton 8-hour ozone nonattainment areas. (See 72 FR 14729). As 
detailed in the proposed approval, EPA found the low-RVP fuel program 
necessary pursuant to Section 211(c)(4)(C) of the CAA. In addition, EPA 
also proposed approval of the State's SIP revision as consistent with 
the provisions of the Energy Policy Act (EPAct).

II. What is our response to comments received on the notice of proposed 
rulemaking?

    During the comment period for the March 29, 2007, proposal we 
received several comments from 16 commenters including the API and the 
Regional Air Pollution Control Agency (RAPCA) of Dayton, Ohio. Six of 
the commenters, including RAPCA, were in favor of the proposed fuel and 
supported EPA approval. A number of commenters also submitted adverse 
comments that were outside the scope of the proposal (e.g., approval of 
reformulated gasoline, corn ethanol). A summary of the relevant 
portions of the adverse comments received on the proposed rule and 
EPA's response to these comments is presented below. EPA does not view 
the adverse comments we received as a basis to disapprove the SIP 
revision. We believe the SIP revision meets the applicable requirements 
of the CAA, and we are approving it.
    Comment: API states ``API supports Ohio's revision to the rule,'' 
providing for low RVP gasoline as of one year after EPA approval of the 
rule. API then states, ``However, it would be unlawful for USEPA to 
approve this SIP revision.'' API thus implicitly recommends that EPA 
not approve Ohio's rule.
    Response: EPA appreciates API's support for Ohio's rule change 
allowing one year lead time from EPA final approval. However, EPA 
disagrees with API's contention that approving Ohio's rule would be 
unlawful, and EPA disagrees with API's recommendation that EPA not 
approve Ohio's rule. The discussion below addresses API's more specific 
comments.
    Comment: API repeats some of the modeling uncertainties that EPA 
noted in its proposed rulemaking, and concludes that ``EPA should 
require that States seeking approval under 211(c)(4)(C) submit accurate 
modeling and back-up analysis as part of the waiver request. Providing 
it later with an attainment demonstration is too late to be useful for 
EPA's fuel waiver analysis.''
    Response: EPA must make judgments as to whether it has the best 
available modeling information and whether the information is of 
adequate quality to support the conclusion being reached. ``EPA has 
undoubted power to use predictive models so long as it explains the 
assumptions and methodology used in preparing the model and provides a 
complete analytic defense should the model be challenged.'' Appalachian 
Power Company v. EPA, 251 F.3d 1026, 1051 (D.C. Cir. 2001) (internal 
citations omitted). EPA also recognizes that any modeling analysis, and 
any projection of future conditions, inherently has uncertainties. 
``That a model is limited or imperfect is not, in itself a reason to 
remand agency decisions based upon it.'' Id. ``It is only when the 
model bears no rational relationship to the characteristics of the data 
to which it is applied that [courts] will hold that the use of the 
model is arbitrary and capricious.'' Appalachian Power Company v. EPA, 
135 F.3d 791, 802 (D.C. Cir. 1998) (internal citations omitted). Thus, 
in this instance EPA believes that it is using the best available 
modeling information, that the information is of adequate quality to 
find low RVP fuel necessary, and that the commenter has provided no 
rationale for EPA to believe otherwise. Further, regardless of what 
information the state provides, directly or indirectly, EPA's 
obligation is to use available information to judge whether a fuel 
program is necessary. EPA agrees that information that Ohio is 
preparing for submittal with its attainment demonstration will not be 
available for EPA's fuel waiver analysis, but notes that such 
information is not required for purposes of making a necessity finding 
under either section 211(c)(4)(C)(i) or EPA's August 1997 ``Guidance on 
Use of Opt-in to RFG and Low RVP Requirements in Ozone SIPs.'' EPA 
believes that the modeling information already available is adequate 
for finding low RVP fuel necessary.
    Comment: API states that the State of Ohio has not made its 
``necessity'' showing because there are non-fuel measures (e.g., E-
check) that are

[[Page 29271]]

reasonable and practicable. API points out that OEPA has already 
adopted and implemented E-check for Dayton-Cincinnati, thus, proving 
that this control measure is both reasonable and practicable. API also 
contends that EPA provides no independent analysis or review of the 
non-fuel measures and that ``it appears that EPA did not review the 
reasons OEPA gives for why E-check is not reasonable or practicable, as 
they do not comment in their proposal on OEPA's rationale''.
    Response: EPA agrees with API's conclusion that E-check is a 
reasonable and practical control measure. However, EPA views the issue 
of whether E-check is reasonable or practicable as irrelevant in making 
a ``necessity'' determination because Cincinnati and Dayton's E-check 
program is currently part of the existing SIP and, thus, is still a 
required control measure in both areas regardless of whether the 
program is currently operating or not. In addition, the modeling 
analysis used in demonstrating ``necessity'' reflects the emission 
reductions associated with the E-check as if the program was still 
operating. EPA has concluded that even with the implementation of all 
non-fuel control measures determined to be reasonable and practicable, 
including E-check, additional VOC reductions are necessary to achieve 
the ozone NAAQS. Further, EPA concluded, based on the information 
available to us, that no other reasonable and practicable non-fuel 
measures were available to the State that would achieve these needed 
emission reductions in a timely manner. Thus the Agency concludes that 
the 7.8 psi RVP fuel program is necessary for attainment of the 
applicable ozone NAAQS.
    EPA disagrees with API's assertion that EPA did not review and take 
into consideration the reasons OEPA outlined in the State's submittal 
regarding why the State considered E-check to be unreasonable or 
impracticable. As provided above, EPA reviewed OEPA's rationale but 
determined that it was irrelevant in making the necessity demonstration 
because E-check is a required program in Ohio's SIP. Regarding API's 
concern that EPA did not provide an independent analysis or review of 
the non-fuel measures, EPA provided the opportunity for the public to 
review and comment on all aspects of Ohio's submittal including the 
evaluation of the non-fuel measures considered by the State. EPA did 
not receive any specific comments questioning either the list of non-
fuel measures considered or the results of the State's analysis. EPA 
believes that the State's assessment adequately identifies and 
evaluates non-fuel measures.
    Comment: An anonymous commenter urges that EPA not approve the 7.8 
RVP gasoline requirement due to deficiencies in the showing that low 
RVP fuel is necessary. First, the commenter objects to the estimation 
of the emission reduction between 2008 and 2009 by calculating one 
seventh of the emission reduction between 2002 and 2009, since 
commenter believes that an ``analysis of whether [pertinent emission 
reductions are] linear'' would show that emission reductions occur 
disproportionately in early years of control programs and only 
minimally later. Second, the commenter observes that the Dayton and 
Cincinnati nonattainment areas are subject to a requirement `` `to 
submit an attainment demonstration that relies on photochemical grid 
modeling,' '' and the commenter believes that ``a completed attainment 
demonstration seems to be necessary'' to ``properly determine whether a 
low-RVP fuel is necessary.'' Third, the commenter believes that ``a 
`weight of evidence' analysis is needed with such modeling.'' The 
commenter concludes that ``USEPA should fully evaluate the necessity of 
such lower RVP fuel in accordance with section 211(c)(4)(C) of the 
Clean Air Act.''
    Response: EPA used the best available information to evaluate 
whether Ohio's low RVP fuel program is necessary. First, the most 
significant VOC emission reductions between 2002 and 2009 are from 
mobile sources, which are yielding relatively linear emission 
reductions resulting from a steady rate of replacement of old dirtier 
vehicles with new cleaner vehicles. (Emissions for NOX 
declined more than the average 2002 to 2009 rate in the early days of 
the NOX SIP Call program and can be expected to decline at 
less than that rate in the future, but EPA's approximation of necessary 
emission reductions applied only to VOC emissions.) EPA considered this 
situation in deciding to apply an assumption of approximately linear 
reductions, and EPA continues to believe that the best available 
information is based on an assumption that VOC emissions are undergoing 
a basically linear decline.
    Second, Dayton and Cincinnati are indeed subject to a requirement 
for attainment demonstrations, for which EPA recommends use of 
photochemical grid modeling, but, under section 211(c)(4)(C)(i), EPA 
may make a necessity finding ``even if the plan for the area does not 
contain an approved demonstration of timely attainment.'' The 
attainment plans are not due until June 15, 2007, and even though this 
requirement applies in the relatively near future, EPA has no 
obligation to delay action on Ohio's fuel request waiting for either 
that date or Ohio's actual submittal. EPA believes it has adequate 
information already to evaluate the necessity of the fuel restrictions 
requested by Ohio.
    Third, EPA indeed recommends ``weight of evidence'' analyses as a 
supplement to attainment demonstrations in some cases. However, just as 
section 211(c)(4)(C) provides that an approved attainment demonstration 
is not a prerequisite for making necessity findings, EPA believes that 
complete ``weight of evidence'' analyses are not a prerequisite for 
making necessity findings. EPA expects that Ohio will submit weight of 
evidence analyses at the same time it submits its attainment 
demonstrations. In the meantime, in the absence of a complete submittal 
by Ohio addressing the potential for model under-prediction as well as 
over-prediction, EPA believes that the best assessment of the necessity 
of a low RVP fuel program in Southwest Ohio is based directly on the 
available modeling information. In summary, EPA concludes that an 
evaluation in accordance with section 211(c)(4)(C) using the best 
available information indicates that Ohio's requested low RVP fuel is 
necessary in Southwest Ohio.
    Comment: A commenter questions whether the benefits of low RVP 
gasoline will be significant. The commenter observes that there are 130 
billion tons of air above the Cincinnati/Dayton area, so that an 
emission reduction of 5.2 tons per day would only reduce concentrations 
by 0.000000004 percent. Finally, the commenter recommends use of a 
``Grease Gator'', marketed by Solvent Systems, for cleaning parts 
without emitting VOC.
    Response: Human health is impaired even at very low air pollutant 
concentrations. The ozone standard is 0.08 parts per million, or 
0.000008 percent of the molecules in ambient air. EPA set the air 
quality standard at this ``trace'' level based on studies showing that 
even seemingly negligible concentrations of ozone can adversely affect 
human health. Typical VOC concentrations sufficient to cause violations 
of this standard are in the same fraction of a part per million range, 
attributable in the Cincinnati/Dayton area to emissions of about 300 
tons per day. Given the low concentrations at which ozone impairs 
health, the implementation of low RVP gasoline will provide a 
significant fraction of the reduction of VOC emissions needed in this 
area. It should be noted, however, that in reviewing

[[Page 29272]]

this SIP revision EPA is limited to determining whether the legal 
criteria for approval are met. The issue before us here is whether the 
criteria for approval in 211(c)(4)(C) are met, and we have determined 
they have been met. EPA appreciates the recommendation of a parts 
cleaning system with zero VOC emissions.
    Comment: Several commenters raised concerns with the concept of 
further expanding the use of boutique fuels. One commenter goes on to 
say that such expansion will further reduce refinery capacity/
efficiency, is likely to cost consumers more, and has the potential to 
cause the Ohio areas to face a gasoline shortage in the event of a fuel 
disruption scenario. Another commenter is concerned that having special 
blends in different parts of the country will cause shortages.
    Response: Due to the heightened concern over supply and price 
issues and the potential for boutique fuel programs to exacerbate these 
issues, Congress directly addressed the issue of boutique fuels in 
several ways in the Energy Policy Act of 2005 (EPAct). EPAct placed 
further restrictions on EPA's authority to approve a state fuel program 
in the SIP. Under EPAct, EPA may approve a state fuel program for a SIP 
only if a fuel is already approved in a SIP for a state in that 
Petroleum Administration for Defense Districts (PADD), and the approval 
does not increase the total number of state fuels on EPA's list of 
fuels. Further, where there is room on the list, prior to approval of a 
new fuel, EPA, with Department of Energy consultation, must find no 
adverse impact on fuel supply and distribution in either the affected 
area or contiguous areas. The 7.8 psi RVP fuel that we are approving 
today is not a new fuel because it is already approved in at least one 
SIP (Indiana, (61 FR 4895, (February 9, 1996)) in the PADD where Ohio 
is located. EPA therefore, does not believe that it is required to make 
a finding of no adverse impact effects of a 7.8 psi RVP fuel on fuel 
supply and distribution in either Dayton and Cincinnati or the 
contiguous areas. EPA also believes that this rule fully complies with 
the applicable EPAct requirements. Further, although we received 
comments from API on this action, none of the comments received from 
the industry side raise any concerns with the industry's ability to 
adequately and efficiently supply the 7.8 psi RVP fuel to the affected 
areas. Further, API's comments state that ``API and OEPA reached an 
agreement on April 4, 2006, that 7.8 RVP fuel will not be required in 
Dayton-Cincinnati until one year after final approval by U.S.EPA. API 
supports this revised rule as in the best interest of the State of Ohio 
and its citizens''.

III. What action is EPA taking?

    EPA is approving a SIP revision submitted by the State of Ohio on 
February 14, 2006, and October 6, 2006, establishing a 7.8 psi RVP fuel 
requirement for gasoline distributed in the Cincinnati and Dayton 8-
hour ozone nonattainment areas. This action is effective on May 31, 
2007. EPA is approving Ohio's fuel requirement into the SIP because EPA 
has found that the requirement is necessary for Southwest Ohio to 
achieve the 8-hour NAAQS for ozone. EPA's approval is consistent with 
the boutique fuel provisions of section 211(c)(4)(C) enacted in EPAct.
    EPA finds that there is good cause for this action to become 
effective by May 31, 2007. The May 31, 2007 effective date for this 
action is authorized under 5 U.S.C. 553(d)(3) which allows an effective 
date less than 30 days after publication ``as otherwise provided by the 
agency for good cause found and published with the rule.'' The purpose 
of the 30-day waiting period prescribed in 553(d) is to give affected 
parties a reasonable time to adjust their behavior and prepare before 
the final rule takes effect. Today's rule, approves Ohio's SIP revision 
requiring the use of 7.8 psi RVP gasoline in the Cincinnati and Dayton 
areas one year after EPA approval of the fuel waiver request under 
section 211(c)(4)(C) of the CAA. RVP control requirements are summer 
control programs that are generally implemented during the summer ozone 
season beginning on June 1. Making this rule effective before the 
beginning of the summer ozone season, will allow the regulated industry 
to avoid having to address multiple RVP requirements during the 2008 
ozone season. In addition, as noted above, the regulated industry has 
had advance notice of this requirement, and the API has agreed to a 
settlement with provisions for the 7.8 psi RVP fuel in these areas 
twelve months following the approval of a fuel waiver by EPA. For these 
reasons, EPA finds good cause under 5 U.S.C. 553(d)(3) for this action 
to become effective on May 31, 2007.

IV. Statutory and Executive Order Reviews

Executive Order 12866: Regulatory Planning and Review

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this 
action is not a ``significant regulatory action'' and, therefore, is 
not subject to review by the Office of Management and Budget.

Executive Order 13211: Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use

    Because it is not a ``significant regulatory action'' under 
Executive Order 12866 or a ``significant regulatory action,'' this 
action is also not subject to Executive Order 13211, (``Actions 
Concerning Regulations That Significantly Affect Energy Supply, 
Distribution, or Use'' (66 FR 28355, May 22, 2001).

Regulatory Flexibility Act

    This action merely approves state law as meeting Federal 
requirements and imposes no additional requirements beyond those 
imposed by state law. Accordingly, the Administrator certifies that 
this rule will not have a significant economic impact on a substantial 
number of small entities under the Regulatory Flexibility Act (5 U.S.C. 
601 et seq.).

Unfunded Mandates Reform Act

    Because this rule approves pre-existing requirements under state 
law and does not impose any additional enforceable duty beyond that 
required by state law, it does not contain any unfunded mandate or 
significantly or uniquely affect small governments, as described in the 
Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4).

Executive Order 13175: Consultation and Coordination With Indian Tribal 
Governments

    This rule also does not have tribal implications because it will 
not have a substantial direct effect on one or more Indian tribes, on 
the relationship between the Federal Government and Indian tribes, or 
on the distribution of power and responsibilities between the Federal 
Government and Indian tribes, as specified by Executive Order 13175 (65 
FR 67249, November 9, 2000).

Executive Order 13132: Federalism

    This action also does not have Federalism implications because it 
does 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 (64 FR 43255, August 
10, 1999). This action merely approves a state rule implementing a 
Federal standard, and does not alter the relationship or the 
distribution of power

[[Page 29273]]

and responsibilities established in the Clean Air Act.

Executive Order 13045: Protection of Children From Environmental Health 
and Safety Risks

    This rule also is not subject to Executive Order 13045 ``Protection 
of Children from Environmental Health Risks and Safety Risks'' (62 FR 
19885, April 23, 1997), because it is not economically significant.

National Technology Transfer Advancement Act

    In reviewing SIP submissions, EPA's role is to approve state 
choices, provided that they meet the criteria of the Clean Air Act. In 
this context, in the absence of a prior existing requirement for the 
state to use voluntary consensus standards (VCS), EPA has no authority 
to disapprove a SIP submission for failure to use VCS. It would thus be 
inconsistent with applicable law for EPA, when it reviews a SIP 
submission, to use VCS in place of a SIP submission that otherwise 
satisfies the provisions of the Clean Air Act. Thus, the requirements 
of section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (15 U.S.C. 272 note) do not apply.

Paperwork Reduction Act

    This rule does not impose an information collection burden under 
the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 
et seq.).

Congressional Review Act

    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. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2). 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 24, 2007. 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).)

    (138) On February 14, 2006, and October 6, 2006, the State of Ohio 
submitted a revision to the Ohio State Implementation Plan. This 
revision is for the purpose of establishing a gasoline Reid vapor 
pressure (RVP) limit of 7.8 pounds per square inch (psi) for gasoline 
sold in the Cincinnati and Dayton 8-hour ozone nonattainment areas
