Approval and Promulgation of Air Quality Implementation Plans;
Pennsylvania; Removal of Allegheny County Requirements Applicable to
Motor Gasoline Volatility in the Allegheny County Portion of the
Pittsburgh-Beaver Valley Area
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing to
approve a state implementation plan (SIP) revision submitted by the
Commonwealth of Pennsylvania, on behalf of the Allegheny County Health
Department (ACHD), on March 19, 2019. This revision seeks removal from
the Pennsylvania SIP of Allegheny County requirements limiting
summertime gasoline volatility to 7.8 pounds per square inch (psi) Reid
Vapor Pressure (RVP), which were originally adopted to
[[Page 17763]]
reduce ozone precursor pollution to address nonattainment of the 1-hour
ozone national ambient air quality standard (NAAQS) in the Allegheny
County portion of the Pittsburgh-Beavery Valley ozone nonattainment
area (hereafter referred to as the Pittsburgh-Beaver Valley Area). In
December 2018, EPA issued a final approval of the Pennsylvania
Department of Environmental Protection's (PA DEP) request to remove
from the SIP the PA DEP requirements limiting the summer RVP of
gasoline in the Pittsburgh-Beaver Valley Area. As part of that action,
EPA also approved the accompanying demonstration prepared by
Pennsylvania that shows that the emission impacts from removal of the
program will not interfere with the area's ability to attain or
maintain any NAAQS. EPA is proposing that this prior approved
noninterference demonstration also serves to support Pennsylvania's
request to remove the separate program imposed by Allegheny County
requiring summer 7.8 psi RVP gasoline and that removal of this
substantially similar, local low-RVP program will not interfere with
the area's ability to attain or maintain the NAAQS. This action is
being taken under the Clean Air Act (CAA).
DATES: Written comments must be received on or before May 28, 2019.

I. Background
A. Federal Gasoline Volatility Controls Under the CAA
Under section 211(c) of the CAA, EPA promulgated regulations on
March 22, 1989 (54 FR 11868) that set maximum Federal limits for the
RVP of gasoline sold during regulatory control periods that were
established on a state-by-state basis in the final rule. The regulatory
control periods applied during the summer months when peak ozone
concentrations were expected. That rule, referred to as Federal Phase I
RVP standards, constituted the first phase of a two-phase nationwide
program that was designed to reduce the volatility of commercial
gasoline during the high ozone season. Depending on the state and
month, Federal Phase I gasoline RVP was not to exceed 10.5 psi, 9.5
psi, or 9.0 psi between calendar years 1989 through 1991. On June 11,
1990 (55 FR 23658), EPA promulgated more stringent Phase II Federal
gasoline volatility standards. These requirements established maximum
RVP standards of 9.0 psi or 7.8 psi, depending on the state location
and the area's initial ozone attainment designation with respect to the
1-hour ozone NAAQS. Phase II was applicable starting in 1992 and
remains in effect, except in areas that have more stringent SIP-
approved RVP control programs in place. These Federal volatility
regulations are codified at 40 CFR 80.27, with the delineation between
areas designated as Federal 9.0 psi RVP volatility attainment areas
codified at 40 CFR 80.27(a)(2)(i), and those areas designated as
Federal 7.8 psi RVP volatility nonattainment areas at 40 CFR
80.27(a)(2)(ii).
The 1990 amendments to the CAA established a new section, 211(h),
to address fuel volatility. Section 211(h)(1) requires EPA to
promulgate regulations making it unlawful to sell, offer for sale,
dispense, supply, offer for supply, transport, or introduce into
commerce gasoline with an RVP level in excess of 9.0 psi during the
high ozone season. Section 211(h)(2) prohibits EPA from establishing a
volatility standard more stringent than 9.0 psi in an attainment area,
except that the Agency may impose a lower (more stringent) standard in
any former ozone nonattainment area redesignated to attainment.
Under Federal Phase II gasoline volatility requirements, which were
promulgated December 12, 1991 (56 FR 64704), EPA modified the Phase II
volatility regulations to make them consistent with section 211(h). The
modified regulations prohibited the sale of gasoline, beginning in
1992, with RVP above 9.0 psi in all areas designated attainment for
ozone. Under the revised Phase II standards published on June 11, 1990
(55 FR 23658), areas are subject to either a 9.0 psi RVP standard, or
to a newly added 7.8 psi ozone season limitation applicable to some
states.
Under these Federal Phase II RVP requirements, the Commonwealth of
Pennsylvania was required to meet a Federal 9.0 psi RVP standard during
the summer RVP control period--except for the Philadelphia Area, which
was at that time was designated as severe ozone nonattainment and as
such was subject to more stringent gasoline requirements of the
reformulated gasoline program established under CAA section 211(k).
[[Page 17764]]
However, Pennsylvania and Allegheny County were later granted a
Federal ``preemption waiver'' under authority of CAA section
211(c)(4)(C), which allows a state to adopt their own more stringent,
state-specific fuel program (or ``boutique'' fuel program) as part of
the Federally-approved SIP. It was this Federal fuel preemption waiver
that enabled Pennsylvania (and Allegheny County) to adopt a more
stringent gasoline volatility program in the Pittsburgh-Beaver Valley
area, as described in more detail in this rulemaking action.
B. History of State and Local Gasoline Volatility Controls Applicable
to the Pittsburgh-Beaver Valley Area
On November 15, 1990, the CAA amendments of 1990 were signed into
law. On November 6, 1991, EPA designated and classified the Pittsburgh-
Beaver Valley Area as moderate nonattainment for the 1979 1-hour ozone
NAAQS, which included: Allegheny, Armstrong, Beaver, Butler, Fayette,
Washington, and Westmoreland Counties. As one of a number of measures
aimed to bring the Pittsburgh-Beaver Valley Area into ozone attainment,
Pennsylvania adopted (among other measures) gasoline RVP limits,
through separate but substantially similar PA DEP and ACHD rules
limiting summertime gasoline volatility in the Pittsburgh-Beaver Valley
Area to 7.8 psi RVP. PA DEP initially adopted a gasoline RVP limit rule
in the November 1, 1997 Pennsylvania Bulletin (27 Pa.B. 5601, effective
November 1, 1997), which is codified in Subchapter C of Chapter 126 of
the Pennsylvania Code of Regulations (25 Pa. Code Chapter 126,
Subchapter C). On April 17, 1998, Pennsylvania submitted this state-
adopted rule to EPA as a formal revision to its approved SIP. EPA
approved Pennsylvania's RVP SIP revision in the June 8, 1998 Federal
Register (63 FR 31116) and codified in the Code of Federal Regulations
at 40 CFR 52.2020(c)(1).
As the local air pollution control agency for Allegheny County, the
ACHD subsequently adopted a substantially similar summertime gasoline
volatility limit rule (Allegheny County Order No. 16782, Article XXI,
sections 2102.40, 2105.90, and 2107.15; effective May 15, 1998, amended
August 12, 1999). On March 23, 2000, PA DEP formally submitted a SIP
revision to EPA (on behalf of ACHD) to incorporate ACHD's gasoline RVP
summertime requirements identified above into the Pennsylvania SIP. EPA
approved that SIP revision, establishing an independent ACHD gasoline
RVP limit, on April 17, 2001 (66 FR 19724), effective June 18, 2001.
PA DEP amended its RVP limit rule in April 2017 to suspend
summertime gasoline RVP limits, formerly applicable to all seven
counties in the Pittsburgh-Beaver Valley Area.\1\ ACHD subsequently
revised its own RVP limit rule (Article XXI, Sec. Sec. 2105.90, and
2107.15 of the Rules and Regulations of the Allegheny County Health
Department; amended February 21, 2019, effective March 3, 2019),
suspending applicability of ACHD's RVP requirements upon the effective
date of EPA's removal of the revised Article XXI sections from the
Allegheny County portion of the Pennsylvania SIP. On March 19, 2019, PA
DEP submitted this SIP revision (on behalf of ACHD) to EPA to request
removal of the ACHD's RVP rule requirements from the Pennsylvania SIP.
This request to remove the ACHD RVP program requirements from the SIP
is the subject of EPA's current rulemaking action.
---------------------------------------------------------------------------
\1\ See Pa Code, Title 26, Chapter 126, Subchapter C (relating
to motor vehicle and fuels programs, gasoline volatility
requirements), effective January 22, 2019. (Pa Bulletin, Vol. 48,
No. 14; April 7, 2018). This rule amended Sec. 126.301 (relating to
compliant fuel requirement) to make Chapter 126, Subchapter C no
longer applicable to the Pittsburgh-Beaver Valley Area upon the
effective date of approval by EPA of the removal of Chapter 126,
Subchapter C as a Federally-enforceable control measure in the
Commonwealth's SIP. EPA approved Pennsylvania's SIP request to
remove the PA DEP RVP requirements of Chapter 126 in a final rule
published December 20, 2018 (83 FR 65301).
---------------------------------------------------------------------------
II. What prompted ACHD to suspend locally adopted gasoline volatility
requirements applicable to Allegheny County?
A. Pennsylvania Legislature Directs PA DEP To Suspend State Gasoline
Volatility Controls Applicable to the Pittsburgh-Beaver Valley Area
In the 2013-14 session, the Pennsylvania General Assembly passed,
and Governor Corbett signed into law, Act 50 (Pub. L. 674, No. 50 of
May 14, 2014), that amended the Pennsylvania Air Pollution Control Act
to direct PA DEP to initiate a process to repeal PA DEP's Pittsburgh-
Beaver Valley Area gasoline RVP requirements. That process culminated
with PA DEP's submission on May 2, 2018 of a SIP revision requesting
that EPA remove from the Pennsylvania portion of the SIP the Pa. Code
RVP provisions of Chapter 126, Subchapter C gasoline RVP limits and
also approve PA DEP's CAA 110(l)-required noninterference demonstration
showing that repeal of PA DEP's RVP requirements would not interfere
with the Pittsburgh-Beaver Valley Area's attainment of any NAAQS.
Pennsylvania's analysis showed that the emissions impact from repeal of
the 7.8 psi RVP summer limit (to be replaced by the Federal 9.0 psi
summertime gasoline RVP requirement) would be fully offset through
substitution of commensurate benefits from another enacted emission
reduction measure reducing emissions from area sources in the
Pittsburgh-Beaver Valley Area, as well as reductions from permanent
shutdown of a glass manufacturing facility in Allegheny County. For
further information on the Commonwealth's supporting demonstration
showing removal of the RVP program from the Pittsburgh-Beaver Valley
Area will not interfere with the area's ability to meet Federal NAAQS,
as well as EPA's analysis of that demonstration, please refer to EPA's
December 20, 2018 (83 FR 65301) final rule approving Pennsylvania's
removal of PA DEP's Chapter 126 low-RVP program from the seven counties
comprising the Pittsburgh-Beaver Valley Area and the docket for that
action.
B. ACHD Amendment of Allegheny County Gasoline Volatility Requirements
Rule To Suspend Local RVP Requirements Applicable to Allegheny County
ACHD subsequently revised its own RVP limit rule (Article XXI,
Sec. Sec. 2105.90, and 2107.15 of the Rules and Regulations of the
Allegheny County Health Department; amended February 21, 2019,
effective March 3, 2019), suspending applicability of ACHD's gasoline
RVP requirements upon the effective date of EPA's removal of the
revised Article XXI sections from the Allegheny County portion of the
Pennsylvania SIP.
The revised ACHD gasoline volatility regulation contains an added
provision suspending the requirements that ban the sale or transfer of
gasoline in Allegheny County non-compliant with a 7.8 psi RVP limit
(between May 1 through September 15). Per ACHD's revised rule (as
amended February 21, 2019), the County's 7.8 psi summer limit and
related requirements (at Article XXI, Sec. Sec. 2105.90 and 2107.15)
will no longer be applicable upon the effective date of EPA's final
action approving removal of the RVP program from the Allegheny County
portion of the Pennsylvania SIP. Upon the effective date of EPA final
action to approve the Commonwealth's request to remove the Allegheny
County 7.8 psi RVP program requirements from the SIP, all state and
local RVP limits for the Pittsburgh-Beaver Valley would be rescinded,
reverting the entire
[[Page 17765]]
Pittsburgh-Beaver Valley Area to the applicable Federal Phase II RVP
requirements.\2\
---------------------------------------------------------------------------
\2\ See EPA's Phase II Volatility Regulations published June 11,
1990 (55 FR 23658), as amended December 12, 1991 (56 FR 64704). EPA
amended Federal Phase II volatility regulations to make them
consistent with CAA section 211(h), prohibiting the sale of gasoline
(beginning in 1992) with RVP above 9.0 psi in all areas designated
attainment for ozone. For areas designated nonattainment, the
regulations retained the original Phase II standards established by
the June 1990 Phase II rule.
---------------------------------------------------------------------------
III. What is the historic reason for adoption of gasoline volatility
control and the status of air quality in the Pittsburgh-Beaver Valley
Area?
The gasoline volatility limit was originally adopted by
Pennsylvania as part of a suite of measures to address ground level
ozone pollution in the Pittsburgh-Beaver Valley Area, which has
historically been designated nonattainment for the ozone NAAQS. Since
passage of the CAA in 1990, portions of the Pittsburgh-Beaver Valley
Area have also been designated nonattainment for the daily and annual
averaging period fine particulate matter (PM2.5) NAAQS.
Since the low-RVP gasoline program affects primarily volatile organic
compounds (VOCs) and nitrogen oxides (NOX) emissions, and to
some degree directly emitted PM2.5 emissions, our
consideration of the impact of removal of this rule on air quality
focuses primarily on those NAAQS to which emission from this program
contribute (either directly or as NAAQS precursor emissions).
A. The Status of the Pittsburgh-Beaver Valley Area With Respect to the
Ozone NAAQS
On November 6, 1991 (56 FR 56694), EPA designated and classified
the Pittsburgh counties of Allegheny, Armstrong, Beaver, Butler,
Fayette, Washington, and Westmoreland Counties as nonattainment for the
1-hour ozone NAAQS promulgated by EPA in 1979. On April 9, 2001,
Pennsylvania submitted a request to redesignate the Pittsburgh-Beaver
Valley Area to attainment of the 1979 1-hour ozone NAAQS, along with a
maintenance plan to demonstrate that the area would continue to attain
for a 10-year period--a plan which relied, in part, on emissions
reductions attributable to the 7.8 psi RVP summertime gasoline
volatility control program. Subsequently, EPA determined that the
Pittsburgh-Beaver Valley Area had attained the 1979 1-hour ozone NAAQS
by its extended attainment date and approved the Commonwealth's 1-hour
redesignation request and maintenance plan SIP revision on November 19,
2001 (66 FR 53094).
On July 18, 1997 (62 FR 38856), EPA issued a revised NAAQS for
ozone, strengthening the primary and secondary standards to 0.080 parts
per million (ppm) and changing the averaging time from 1-hour to 8-
hours. In May of 2012, EPA classified the Pittsburgh-Beaver Valley Area
as moderate nonattainment under section 181 of the CAA.\3\ On April 4,
2013, EPA determined that the Pittsburgh-Beaver Valley Area had
attained the 1997 8-hour ozone NAAQS by its applicable attainment date
(based on air monitoring data for the 2007-2009 period) and warranted a
clean data determination. This latter determination suspended certain
CAA planning requirements for the Area, including requirements for an
attainment demonstration, associated reasonable further progress plan,
contingency measures, reasonably available control measure (RACM)
analysis, and other CAA part D planning requirements for moderate ozone
nonattainment areas, for as long as the area continued to monitor
attainment of the NAAQS.
---------------------------------------------------------------------------
\3\ In 2012, EPA finalized revisions to the 2004 Phase 1
Implementation Rule for the 1997 8-hour ozone NAAQS that specified
requirements to meet the 1997 ozone NAAQS. (77 FR 28424, May 14,
2012). The revisions were EPA's response to a December 22, 2006
decision in South Coast Air Quality Management District v. EPA, 472
F.3d 882 (D.C. Cir. 2006), directing EPA to classify areas under
Part D of the CAA. As a result, EPA reclassified the former subpart
1 nonattainment areas, like the Pittsburgh Beaver Valley Area, under
subpart 2. The 1997 8-Hour Ozone NAAQS was eventually revoked on
April 6, 2015.
---------------------------------------------------------------------------
On March 27, 2008 (73 FR 16436), EPA strengthened the 8-hour NAAQS
from 0.080 to 0.075 ppm. On May 21, 2012 (77 FR 30088), EPA designated
and classified the Pittsburgh-Beaver Valley Area as marginal
nonattainment for the 2008 8-hour ozone NAAQS. On March 6, 2015 (80 FR
12264), EPA published its ozone implementation rule for the 2008 ozone
NAAQS, which established the date of July 20, 2016 as the deadline for
marginal areas to attain the 2008 8-hour ozone NAAQS. On December 6,
2016 (81 FR 87819), EPA determined that the Pittsburgh-Beaver Valley
Area had attained the 2008 ozone NAAQS by that July 20, 2016
deadline.\4\ The Pittsburgh-Beaver Valley Area continues to attain the
2008 ozone NAAQS for the most recent 2016-2018 three-year monitoring
period.
---------------------------------------------------------------------------
\4\ On February 16, 2018, the D.C. Circuit Court issued an
opinion on the EPA's regulations implementing the 2008 ozone NAAQS,
known as the 2008 Ozone SIP Requirements Rule. South Coast Air
Quality Mgmt. Dist. v. EPA, No. 15-1115 (D.C. Cir. Feb. 16, 2018).
The D.C. Circuit Court found certain provisions from the 2008 Ozone
SIP Requirements rule unreasonable including EPA's provision for a
``redesignation substitute.'' The D.C. Circuit Court vacated these
provisions and found redesignations must comply with all required
elements in CAA section 107(d)(3) and thus found the ``redesignation
substitute'' which did not require all items in CAA section
107(d)(3)(E) violated the CAA and was thus unreasonable. The D.C.
Circuit Court also vacated other provisions relating to anti-
backsliding in the 2008 Ozone SIP Requirements Rule as the Court
found them unreasonable. Id. The D.C. Circuit Court found other
parts of the 2008 Ozone SIP Requirements Rule unrelated to anti-
backsliding and this action reasonable and denied the petition for
appeal on those. Id.
---------------------------------------------------------------------------
On October 1, 2015 (80 FR 65291), EPA promulgated a revised ozone
NAAQS of 0.070 ppm. On November 6, 2017 (82 FR 54232), EPA issued final
2015 ozone NAAQS designations for most U.S. counties, designating all
seven Pittsburgh-Beaver Valley Area counties as ``attainment/
unclassifiable.''
Pennsylvania's April 19, 2019 SIP submittal for removal of the RVP
program in Allegheny County relies upon a demonstration of
noninterference, per the requirements of CAA section 110(l), that was
originally submitted by PA DEP as part of its May 2, 2018 SIP revision
for removal of the state RVP program in the larger Pittsburgh-Beaver
Valley Area--a substantially similar state RVP requirements rule that
geographically overlaps Allegheny County's rule. EPA approved
Pennsylvania's May 2, 2018 SIP noninterference demonstration as part of
our December 20, 2018 approval of that SIP revision (83 FR 65301). This
SIP-approved 110(l) demonstration includes EPA updated photochemical
grid modeling results for the 2008 ozone NAAQS (See Appendix H of
Pennsylvania's May 2, 2018 SIP revision, which is also appended for
reference as Appendix H to the March 19, 2019 SIP requesting removal of
Allegheny County's RVP program), based on updated electric generating
unit data for 2017.\5\ This forecast data predicts that the Pittsburgh-
Beaver Valley Area will continue to attain the 2008 ozone NAAQS and
will remain in attainment of the 2015 ozone NAAQS by 2023.

---------------------------------------------------------------------------
B. The Status of the Pittsburgh-Beaver Valley Area With Respect to the
Fine Particulate Matter NAAQS
On October 17, 2006, EPA published a revised 24-hour
PM2.5 NAAQS (71 FR 61144). On November 3, 2009, EPA
[[Page 17766]]
designated the Pittsburgh-Beaver Valley Area as nonattainment for the
2006 PM2.5 NAAQS (74 FR 58688) under CAA part D, subpart 1.
On June 2, 2014, EPA reclassified the Pittsburgh-Beaver Valley Area as
moderate nonattainment under CAA part D, subpart 4 (79 FR 31566),
including all of Beaver, Butler, Washington, and Westmoreland Counties
and portions of Allegheny, Armstrong, Greene, and Lawrence Counties. On
May 2, 2014, EPA determined that the Pittsburgh-Beaver Valley Area was
in attainment of the 2006 annual and 24-hour PM2.5 NAAQS
based on 2010-2012 ambient monitoring data (79 FR 25014). On October 2,
2015 (80 FR 59624), EPA approved a request from Pennsylvania to
redesignate the Pittsburgh-Beaver County Area to attainment of the 1997
annual and 2006 24-hour PM2.5 NAAQS.
On January 15, 2013, EPA published revised annual and 24-hour
PM2.5 NAAQS (78 FR 3086). On April 7, 2015, EPA designated
Allegheny County as moderate nonattainment of the 2012 annual
PM2.5 NAAQS (80 FR 18535).\6\ Allegheny County continues to
be nonattainment for the 2012 annual PM2.5 NAAQS.
---------------------------------------------------------------------------
\6\ This action corrects an initial final designations action
for the 2012 PM2.5 NAAQS, which was signed by EPA on
December 18, 2014 and published January 15, 2015 (80 FR 2206). This
correction included more recently available data for use in
designating certain areas of the country.
---------------------------------------------------------------------------
IV. What is EPA's analysis of the Commonwealth's submittal?
State/local control of motor gasoline is preempted by CAA section
211(c)(4)(A), except in cases where EPA has granted a preemption waiver
under 211(c)(4)(B) or (C) as part of a SIP approval. As such a SIP-
approved, Federally preempted CAA 211(c)(4) ``boutique fuel'' program,
Allegheny County's RVP control program is not a mandatory measure
required to address nonattainment under Part D of Subchapter 1 of the
CAA. Nor are boutique fuels subject to ``anti-backsliding'' as it
relates to a revoked NAAQS (e.g., the 1979 1-hour or 1997 ozone NAAQS)
in the case where EPA adopts a more stringent NAAQS (e.g., the 2015
ozone NAAQS), since state/locally-adopted boutique fuels are not an
``applicable requirement'' that must be retained as a SIP obligation
(in certain situations) where a NAAQS has been revoked by EPA.\7\ Nor
does section CAA section 193, applicable to pre-1990 implemented or
required rules, apply because this boutique fuel rule was neither
required or enacted prior to that date.
---------------------------------------------------------------------------
\7\ For instance, in the case of the 2008 Ozone Implementation
Rule (40 CFR part 51, subpart AA), applicable requirements for
purposes of anti-backsliding are defined at 40 CFR 51.1100(o).
---------------------------------------------------------------------------
Therefore, EPA's primary consideration for determining the
approvability of Pennsylvania's request to rescind the requirements for
a gasoline volatility control program is whether this requested action
complies with section 110 of the CAA, specifically section 110(l).\8\
Section 110(l) of the CAA requires that a revision to the SIP not
interfere with any applicable requirement concerning attainment and
reasonable further progress (as defined in section 171), or any other
applicable requirement of the CAA. EPA evaluates each SIP revision for
CAA 110(l) noninterference compliance on an individual basis. EPA
interprets CAA section 110(l) as applying to all NAAQS that are in
effect, including those that have been promulgated, but for which EPA
has not yet made designations.
---------------------------------------------------------------------------
\8\ CAA section 193, with respect to removal of requirements in
place prior to enactment of the 1990 CAA Amendments, is not relevant
because Pennsylvania's RVP control requirements in the Pittsburgh-
Beaver Valley Area were not included in the SIP prior to enactment
of the 1990 CAA amendments.
---------------------------------------------------------------------------
In the absence of an attainment demonstration that shows no
interference with any applicable NAAQS or requirement of the CAA under
section 110(l), EPA believes it is appropriate to allow states to
substitute equivalent emissions reductions to compensate for any
potential emission increases caused by a change to a SIP-approved
program, so long as net actual emissions to the air do not increase.
``Equivalent'' emission reductions mean reductions which are equal to
or greater than those reductions achieved by the control measure
approved in the SIP, which in this case is 7.8 psi RVP gasoline. To
show that compensating emission reductions are equivalent, modeling or
adequate justification must be provided. The compensating, equivalent
or greater reductions must represent real, new emissions reductions
achieved in a contemporaneous time frame to the change of the existing
SIP control measure, in order to preserve the status quo level of
emissions in the air. In addition to being contemporaneous, the
equivalent emissions reductions must also be permanent, enforceable,
quantifiable, and surplus to be approved into the SIP.
In its May 2, 2018 SIP revision, PA DEP submitted a section 110(l)
demonstration that relies upon emission reductions from another
emission control measure (and a permanently shutdown stationary source)
to fully offset any potential increase in emissions that would
otherwise result from removal of the SIP approved 7.8 psi RVP
summertime gasoline requirement in the Pittsburgh-Beaver Valley Area.
Specifically, PA DEP demonstrated that emission reductions in the
Pittsburgh-Beaver Valley Area from the 7.8 psi RVP program are fully
offset by: (1) Reductions from an adopted, implemented Pennsylvania
regulation relating to the use and application of adhesives, sealants,
primers, and solvents at 25 Pa. Code Section 129.77 and (2) the
permanent shutdown of a facility in the Pittsburgh-Beaver Valley Area.
The substitute emissions reduction measures were demonstrated to be
quantifiable, permanent, surplus, enforceable, and contemporaneous
(i.e. occurring at approximately the same time as cessation of the low-
RVP fuel program). Upon removal of the state 7.8 psi summertime RVP
program, the Federal 9.0 psi RVP limit becomes the applicable fuel
volatility control program in the Area.
EPA approved the Commonwealth's CAA 110(l) noninterference
demonstration supporting removal of the 7.8 psi RVP gasoline program in
the Pittsburgh-Beaver Valley Area on December 20, 2018 (83 FR 65301).
The PA DEP's 7.8 psi RVP control program for the entire Pittsburgh-
Beaver Valley Area (under Pa Code Chapter 126) is similar in legal
substance to that of Allegheny County's 7.8 psi RVP program (under
Article XXI of the County's Rules and Regulations). Because of the
similarity of the two programs, the March 19, 2019 SIP revision
requesting removal of ACHD's 7.8 psi RVP program from the SIP relies
upon the Commonwealth's prior approved noninterference demonstration to
show that removal of the ACHD program will not interfere with
attainment (or other CAA applicable requirements) of any NAAQS in the
Pittsburgh-Beaver Valley Area. The March 19, 2018 SIP revision contains
a copy of the PA DEP's earlier demonstration, for reference, without
changing the substance of that prior demonstration. Because of the
similarity between the ACHD county low-RVP rule and the areawide PA DEP
low-RVP rule, EPA agrees with this approach to demonstrating that
removal of ACHD's 7.8 psi RVP program for Allegheny County will not
require additional evaluation for CAA 110(l) noninterference beyond the
showing made by PA DEP for the 7.8. psi RVP program suspension in the
Pittsburgh-Beaver Valley Area.

V. Impacts on the Boutique Fuels List
Section 1541(b) of the Energy Policy Act of 2005 required EPA, in
consultation with the U.S. Department of Energy, to determine the
number of fuels programs approved into all SIPs as of September 1, 2004
and to publish a list of such fuels. On December 28, 2006 (71 FR
78192), EPA published the list of boutique fuels, as it existed at that
time. EPA maintains the current list of boutique fuels on its website
at: https://www.epa.gov/gasoline-standards/state-fuels. The final list
of boutique fuels was based on a fuel type approach. CAA section
211(c)(4)(C)(v)(III) requires that EPA remove a fuel from the published
list if it is either identical to a Federal fuel or is removed from the
SIP in which it is approved. Under the adopted fuel type approach, EPA
interpreted this requirement to mean that a fuel would have to be
removed from all SIPs in which it was approved prior to being removed
from the list (71 FR 78195).
The 7.8 psi RVP fuel program (as required by Allegheny County
Article XXI), as approved into Pennsylvania's SIP, is a fuel type that
is included in EPA's boutique fuel list, as shown in a state-by-state
listing of boutique fuels (71 FR 78198-99). The list of states and
areas where federal 7.8 psi and 9.0 psi low-RVP gasoline are currently
required can also be referenced on EPA's Gasoline Reid Vapor Pressure
web page (https://www.epa.gov/gasoline-standards/gasoline-reid-vapor-pressure). On that list, Allegheny County, Pennsylvania is currently
listed as a partial area boutique fuel program for Pittsburgh,
Pennsylvania. Subsequent to the final effective date of EPA's approval
of Pennsylvania's March 19, 2019 SIP revision to remove Allegheny
County's Rules and Regulations, Article XXI RVP requirement from the
SIP, EPA will update the State Fuels and Gasoline Reid Vapor Pressure
web pages with the effective date of the SIP removal. After the
effective date of the final action on the March 19, 2019 SIP revision,
EPA will remove the 7.8 psi RVP fuel type for Pennsylvania from the
list of boutique fuels.
VI. What Action is EPA taking?
EPA has reviewed Pennsylvania's March 19, 2019 SIP revision
requesting removal of the Allegheny County low-RVP rule and related
requirements from the Pennsylvania SIP. EPA is proposing to approve
Pennsylvania's March 19, 2019 SIP revision request to remove gasoline
RVP-related provisions of Article XXI of the ACHD's Rules and
Regulations from the Allegheny County portion of the Commonwealth's
SIP--including Part E, Subpart 9, section 2105.90 (related to gasoline
volatility) and Part G, section 2107.15 (related to test methods for
gasoline RVP).
EPA is proposing to remove Allegheny County's 7.8 psi RVP
requirements from the approved SIP, as codified at 40 CFR
52.2020(c)(2). This proposed removal from the approved Pennsylvania SIP
is supported by a CAA noninterference demonstration prepared by PA DEP
in support of the May 2018 SIP revision that requested removal of the
Commonwealth's 7.8 psi RVP program in the larger Pittsburgh-Beaver
Valley Area--the removal of which EPA approved in the final rule
published December 20, 2018 (83 FR 65301). In the March 19, 2019 SIP
revision submitted by PA DEP on behalf of ACHD, ACHD references this
demonstration, which analyzes the suspension of 7.8 psi gasoline for
the entire Pittsburgh-Beaver Valley Area, including Allegheny County.
With this action, EPA is also proposing to approve the Commonwealth's
use of the previously approved CAA 110(l) demonstration from its May 2,
2018 submission to demonstrate that removal of the Allegheny County
low-RVP gasoline program does not interfere with the Commonwealth's
ability to attain or maintain any NAAQS in the Pittsburgh-Beaver Valley
Area. Our approval of the May 2, 2018 SIP submittal is in accordance
with requirements for SIP actions under CAA section 110.
EPA is soliciting public comments on the issues discussed in this
document. Since EPA already approved the Commonwealth's technical
demonstration considering the emissions impact of the removal of 7.8
psi RVP programs from the Pittsburgh-Beaver Valley Area (as part of its
December 2018 approval of Pennsylvania's request to remove the PA DEP
RVP requirements in the same area), EPA is not soliciting public
comment on the technical merits of that approved demonstration. Any
comments received will be considered by the Agency before EPA takes
final action.
VII. Statutory and Executive Order Reviews
Under the CAA, the Administrator is required to approve a SIP
submission that complies with the provisions of the CAA and applicable
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in
reviewing SIP submissions, EPA's role is to approve state choices,
provided that they meet the criteria of the CAA. Accordingly, this
action merely approves state law as meeting Federal requirements and
does not impose additional requirements beyond those imposed by state
law. For that reason, this proposed action:
Is not a ``significant regulatory action'' subject to
review by the Office of Management and Budget under Executive Orders
12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21,
2011);
Is not an Executive Order 13771 (82 FR 9339, February 2,
2017) regulatory action because SIP approvals are exempted under
Executive Order 12866.
Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
Is certified as not having a significant economic impact
on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.);
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);
Does not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
Is not an economically significant regulatory action based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
Is not subject to requirements of Section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272
note) because application of those requirements would be inconsistent
with the CAA; and
Does not provide EPA with the discretionary authority to
address, as appropriate, disproportionate human health or environmental
effects, using practicable and legally permissible methods, under
Executive Order 12898 (59 FR 7629, February 16, 1994).
In addition, this proposed rule to approve Pennsylvania's request
to remove ACHD's gasoline volatility regulatory requirements from the
Pennsylvania SIP does not have tribal implications as specified by
Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP
is not approved to apply in Indian country located in the state, and
EPA notes that it will not impose substantial direct costs on tribal
governments or preempt tribal law.
