I. Background
Ozone is a gas composed of three
oxygen atoms. Ground-level ozone is
generally not emitted directly from a
vehicle’s exhaust or an industrial
smokestack but is created by a chemical
reaction between nitrogen oxides (NOX)
and volatile organic compounds (VOC)
in the presence of sunlight and high
ambient temperatures. VOC and NOX
emissions often are referred to as
‘‘precursors’’ to ozone formation. Thus,
ozone is known primarily as a
summertime air pollutant. Motor
vehicle exhaust and industrial
emissions, gasoline vapors, chemical
solvents and natural sources can emit or
contain NOX and/or VOC. Urban areas
tend to have high concentrations of
ground-level ozone, but areas without

significant industrial activity and with
relatively low vehicular traffic are also
subject to increased ozone levels
because wind carries ozone and its
precursors hundreds of miles from their
sources. In 1979, under section 109 of
the Clean Air Act (CAA or the Act), the
EPA established the primary and
secondary National Ambient Air Quality
Standards (NAAQS) for ozone at 0.12
parts per million (ppm) averaged over a
1-hour period (44 FR 8202, February 8,
1979). In 1997, we revised the primary
and secondary NAAQS for ozone to set
the acceptable level of ozone in the
ambient air at 0.08 ppm, averaged over
an 8-hour period (62 FR 38856, July 18,
1997). In 2008, we further revised the
primary and secondary ozone NAAQS
to 0.075 ppm, averaged over an 8-hour
period (73 FR 16436, March 27, 2008).
In 2015, we again revised the primary
and secondary ozone NAAQS to 0.070
ppm, averaged over an 8-hour period
(73 FR 16436, March 27, 2008). For
additional information on ozone, visit
https://www.epa.gov/ozone-pollution.
Stage II vapor recovery is an air
pollution control technology for
automobiles and other on-road mobile
sources. When an automobile or other
vehicle is brought into a gas station to
be refueled, the empty portion of the gas
tank on the vehicle contains gasoline
vapors, which are VOCs. When liquid
gasoline is pumped into the partially
empty gas tank in the vehicle the vapors
are displaced out of the tank as the tank
fills with liquid gasoline. Where air
pollution control technology is not
used, these vapors are emitted into the
air. In the atmosphere, these VOCs can,
in the presence of sunlight, react with
NOX and VOCs from other sources to
form ozone. The Stage II system consists
of special nozzles and coaxial hoses at
each gas pump that capture vapor from
the vehicle’s fuel tank and route them
to underground or above ground storage
tanks during the refueling process. Stage
II vapor recovery systems are
specifically installed at gasoline
dispensing facilities and capture the
refueling fuel vapors at the gasoline
pump nozzle. The system directs the
displaced vapors back to the
underground storage tank at the gasoline
dispensing facility to prevent the vapors
from escaping to the atmosphere.
Onboard refueling vapor recovery
(ORVR) is another emission control
system that can capture fuel vapors from
vehicle gas tanks during refueling.
ORVR systems are carbon canisters
installed directly on automobiles to
capture the fuel vapors displaced from
the gasoline tank before they are
released to the atmosphere. The fuel
vapors captured in the carbon canisters

are then combusted in the engine when
the automobile is started and operated
after refueling.
Stage II vapor recovery systems and
vehicle ORVR systems were initially
both required by the 1990 Amendments
to the CAA, with Stage II requirements
applying to certain nonattainment areas.
Under CAA section 182(b)(3) ozone
nonattainment areas classified as
moderate and above were required to
adopt Stage II requirements. CAA
section 202(a)(6), requires an onboard
system of capturing vehicle refueling
emissions, commonly referred to as an
ORVR system. In 1994, the EPA
promulgated ORVR standards (59 FR
16262, April 6, 1994). Section 202(a)(6)
of the CAA required that the EPA’s
ORVR standards apply to light-duty
vehicles manufactured beginning in the
fourth model year after the model year
in which the standards were
promulgated, and that ORVR systems
provide a minimum evaporative
emission capture efficiency of 95
percent.1 ORVR equipment has been
phased in for new light duty vehicles
(passenger vehicles) beginning with
model year 1998 and starting with
model year 2001 for light-duty trucks
and most heavy-duty gasoline powered
vehicles. Since 2006, ORVR has been a
required emissions control on nearly all
new gasoline-powered highway vehicles
having less than 14,000 pounds gross
vehicle weight rating. CAA section
202(a)(6) provides discretionary
authority to the Administrator, by rule,
to revise or waive the application of the
Stage II requirements for areas classified
as Serious, Severe, or Extreme for ozone,
as appropriate, after such time as the
Administrator determines that onboard
emissions control systems are in
widespread use throughout the motor
vehicle fleet.
On May 16, 2012, the EPA issued a
national rulemaking making the finding
that ORVR systems are in ‘‘widespread
use’’ and determined that emission
reductions from ORVR alone are
essentially equal to and will soon
surpass the emission reductions
achieved by Stage II alone (see 77 FR
28772 at 28772). In the May 16, 2012
action, we noted that each year, nonORVR-equipped vehicles continue to be
replaced with ORVR-equipped vehicles
and Stage II and ORVR systems capture
the same VOC emissions and thus, are
redundant. Id. The EPA also determined
that ORVR systems are in widespread
use and waived the Stage II requirement
for gasoline dispensing facilities if doing

certain ozone nonattainment areas, ORVR
requirements apply to vehicles everywhere.

so did not interfere with attaining or
maintaining the ozone standards. Id. at
28776–28779. The EPA also noted that
any state currently implementing Stage
II vapor recovery programs may submit
SIP revisions that would allow for the
phase-out of Stage II vapor recovery
systems including a CAA section 110(l)
analysis showing that its removal did
not interfere with attaining or
maintaining the ozone standards. Id.
The Portland/Vancouver area was
designated an interstate ozone
nonattainment area in 1978. On
November 15, 1990, the CAA
Amendments of 1990 were enacted.
(Pub. L. 101–549, 104 Stat. 2399,
codified at 42 U.S.C. 7401–7671q).
Under section 181(a)(1) of the 1990
CAA, the area was further classified as
a ‘‘Marginal’’ ozone nonattainment area.
This interstate nonattainment area
consisted of the southern portion of
Clark County, Washington, and portions
of Multnomah, Clackamas, and
Washington Counties in Oregon. In
1997, the EPA redesignated the
Portland/Vancouver area to attainment
(62 FR 27204, May 19, 1997). The
Portland/Vancouver area was
designated as ‘‘unclassifiable/
attainment’’ due to the data showing the
area was below the new NAAQS for
subsequent updates, including the 1997
8-hour ozone NAAQS (69 FR 23857,
April 30, 2004), the 2008 8-hour ozone
NAAQS (77 FR 30088, May 21, 2012),
and the 2015 8-hour ozone NAAQS (82
FR 54232, November 16, 2017).
The Portland/Vancouver area was not
subject to Stage II requirements under
the 1990 Clean Air Act Amendments as
it was classified as Marginal
nonattainment for the 1-hour NAAQS
for ozone, rather than Moderate or
above. However, SWCAA in
coordination with the Washington
Department of Ecology submitted
SWAPCA 491 ‘‘Emission Standards and
Controls for Sources Emitting Gasoline
Vapors’’ (state effective November 21,
1996, subsequently renamed to SWCAA
491) which contained Stage II
requirements as a SIP-strengthening
measure approved concurrently with
redesignation of the Portland/Vancouver
area to attainment (see proposed
rulemaking, 62 FR 10501, March 7,
1997, at page 10507). On August 11,
2015 (80 FR 48033), the EPA approved
SWCAA’s maintenance plan update for
the Vancouver portion of the Portland/
Vancouver area that specifically
anticipated and modeled widespread
use of ORVR and the full
decommissioning of Stage II in the
modeling demonstration of continued
attainment through 2015. The SWCAA

II. SWCAA’s SIP Revision
On June 22, 2023, SWCAA, in
coordination with the Washington
Department of Ecology as the Governor’s
designee for revisions to the SIP,
submitted the current version of
SWCAA 491 ‘‘Emission Standards and
Controls for Sources Emitting Gasoline
Vapors’’ (state effective February 7,
2020) for EPA approval. Since the EPA’s
last approval of SWCAA 491, SWCAA
revised the regulations four times.
Effective June 24, 2000, SWCAA
updated the regulations to revise
applicability of the Stage II vapor
recovery program, which is now
replaced by the applicability provisions
of the current SWCAA 491. Other
changes to SWCAA 491, effective June
24, 2000, are generally SIPstrengthening in nature including the
addition of gasoline marine vessel
loading and unloading vapor control
requirements, which are now contained
in the current version of SWCAA 491.
The exact revisions in 2000 are in
redline/strikeout format included in the
docket for this action under WSR 00–
11–149. Effective March 18, 2001 (WSR
01–05–067), SWCAA made minor
changes to SWCAA 491 to reflect the
name change from ‘‘Southwest Pollution
Control Authority’’ to ‘‘Southwest Clean
Air Agency.’’ Effective June 18, 2017
(WSR 17–11–080), SWCAA
consolidated all agency fees into a
single location and updated the cross
reference in SWCAA 491–030
accordingly. We note that the 2000,
2001, and 2017 revisions to SWCAA 491
were not previously submitted as
updates to the SIP. However, to the
extent these revisions are retained in the
current version of SWCAA 491
submitted for approval, we are
proposing to determine that these
relatively minor changes since our last
update to the SIP in 1997 are
approvable.
The most substantive changes to
SWCAA 491 since the EPA’s last
approval are detailed in WSR 20–03–
031, state effective February 7, 2020.
Among other changes, this revision to
SWCAA 491 included the following:
added a requirement to install enhanced
conventional (ECO) nozzles; added a
requirement that low permeation hoses
be installed on higher volume gasoline
dispensing facilities without balance
type Stage II vapor recovery equipment
by no later than January 1, 2023; added
a requirement for annual testing of Stage

Jkt 259001
I vapor recovery systems; 2 added a
requirement that new or upgraded
gasoline storage tanks be equipped with
Stage I enhanced vapor recovery
equipment; removed a requirement that
gasoline dispensing facilities install
Stage II vapor recovery equipment;
allowed removal from service of Stage II
vapor recovery equipment compatible
with ORVR on or after January 1, 2023;
allowed removal from service of Stage II
vapor recovery equipment incompatible
with ORVR on or after January 3, 2020;
required removal from service of Stage
II vapor recovery equipment
incompatible with ORVR no later than
January 1, 2023; and revised the
applicability threshold for low flow
nozzles to align SWCAA rules with
Federal rules. In the SIP submittal,
SWCAA provided a demonstration that
VOC emission reductions from
enhanced conventional nozzles and low
permeation hoses will outweigh the
annual emissions impact of removing
Stage II requirements. Therefore,
SWCAA requested removal of Stage II
vapor recovery system requirements in
the SIP for SWCAA’s jurisdiction.
III. The EPA’s Evaluation of the
Revision
The EPA’s primary consideration for
determining the approvability of
SWCAA’s revisions to remove Stage II
vapor control requirements and provide
for decommissioning of Stage II
equipment within SWCAA’s
jurisdiction is whether these revisions
comply with section 110(l) of the Act.
Section 110(l) requires that a revision to
the SIP not interfere with any applicable
requirement concerning attainment and
reasonable further progress (RFP), or
any other applicable requirement of the
Act. The EPA can approve a SIP
revision that removes or modifies
control measures in the SIP once the
state or local agency makes a
‘‘noninterference’’ demonstration that
such removal or modification will not
interfere with attainment of the NAAQS,
RFP, or any other CAA requirement.
The EPA reviewed SWCAA’s
submittal with the revised SWCAA 491
regulatory text as well as the
accompanying analysis of emissions
impacts. We propose to determine that
SWCAA’s June 22, 2023, SIP revision
addresses the EPA’s Widespread Use for
Onboard Refueling Vapor Recovery and
Stage II Waiver (77 FR 28772) and is
consistent with the EPA’s ‘‘Guidance on
Removing Stage II Gasoline Vapor
2 Stage I vapor recovery is a system in which
gasoline vapors are forced from the storage tank into
a vapor-tight gasoline tank truck or vapor collection
and control system through direct displacement by
the gasoline loaded into the storage tank.

Control Programs from State
Implementation Plans and Assessing
Comparable Measures’’ (EPA–457/B–
12–001, August 7, 2012).3 In accordance
with the EPA 2012 Guidance on
Removing Stage II, SWCAA submitted a
demonstration that the Stage II
decommissioning will not interfere with
attainment or maintenance of the ozone
NAAQS. This demonstration was based
on an analysis of precursor VOC
emissions from removal of Stage II
controls at GDFs, as well as emission
reduction benefits from other changes to
the regulations such as requirements for
enhanced conventional nozzles and low
permeation hoses. SWCAA estimated
emissions impacts using the guidance
methodologies from the EPA 2012
Guidance showing an overall benefit to
air quality and a reduction of VOC
emissions upon full implementation of
the rule requirements in 2023. SWCAA
estimated the impact on emissions from
decommissioning Stage II in its
jurisdiction by using EPA approved
equations from the same 2012 guidance,
to assess compliance with CAA 110(l).
A detailed spreadsheet with the
equation calculations and supporting
inputs is included in the docket for this
action.
The demonstration indicates that the
emissions benefit of retaining Stage II
requirements is rapidly diminishing
with vehicle fleet turnover and ORVR
penetration. As discussed in the EPA
2012 Guidance, the EPA has developed
equations to assist states in evaluating
the emissions consequences of phasing
out existing Stage II programs. These
equations may be used to calculate an
‘‘increment,’’ which identifies the areawide emission control gained from
Stage II installations as ORVR
technology phases in. For example,
using the equations in the EPA 2012
Guidance, SWCAA calculated the
increment declining from 4.0% in 2020
to 1.1% in 2023 for Clark County, the
most populous county in SWCAA’s
jurisdiction. Projecting these increments
to full implementation of the rule in
2023, the removal of Stage II vapor
recovery systems would result in
minimal increases in VOC emissions of
18.31 tons per year (tpy) for SWCAA’s
entire jurisdiction. Additionally,
SWCAA calculated the emission
reduction benefits of enhanced
conventional nozzles and low
permeation hoses. These emission
reduction benefits are estimated to be
33.84 tpy, outweighing the emissions
increase from decommissioning Stage II

requirements. Overall, the 2020
regulatory changes are projected to
result in a net reduction of 15.99 tpy
VOC with full implementation of the
rule. In addition, the EPA expects that
market saturation of ORVR-equipped
vehicles will remain static or increase in
the years after 2023, meaning the air
quality benefits of these changes will
continue into the future.
Lastly, the removal of Stage II is
consistent with the current maintenance
plan update for the Vancouver portion
of the Portland/Vancouver ozone area
(80 FR 48033, August 11, 2015). As
previously discussed, this maintenance
plan update was approved by the EPA
in 2015. The associated modeling,
included in the docket for this action,
anticipated the decommissioning of
Stage II in the projection of continued
ozone attainment for the 1997 8-hour
ozone NAAQS.4 For the 2008 and 2015
ozone NAAQS, all counties within
SWCAA’s jurisdiction are designated
attainment/unclassifiable. We believe
that removal of Stage II vapor recovery
systems would have a negligible impact
on ozone levels which are offset by the
emission reduction benefits of other
requirements in the revised SWCAA
491. Thus, we proposed to determine
that approval of the SIP revision would
not interfere with any applicable
requirement concerning attainment and
maintenance of any ozone standard and
is compliant with CAA section 110(l).

IV. Proposed Action
We are proposing to find that
SWCAA’s demonstration for removal of
Stage II equipment meets section 110(l)
of the Act. Therefore, we are proposing
to approve and incorporate by reference
SWCAA 491 ‘‘Emission Standards and
Controls for Sources Emitting Gasoline
Vapors’’ state effective February 7, 2020.
This version of the regulation removes
from the Washington SIP the
requirement for Stage II vapor recovery
systems in SWCAA’s jurisdiction and
adds additional VOC controls such as
the installation of enhanced
conventional nozzles and low
permeation hoses, as well as other
historic changes since the EPA’s last
approval as discussed in section II of
this preamble.

discussed in section IV of this preamble.
The EPA has made, and will continue

VI. Statutory and Executive Order
Reviews
Under the Clean Air Act, the
Administrator is required to approve a
SIP submission that complies with the
provisions of the Clean Air Act 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 Clean Air Act. 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 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 14094 (88 FR
21879, April 11, 2023);
• 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 subject to Executive Order
13045 (62 FR 19885, April 23, 1997)
because it approves a state program;
• Is not a significant regulatory action

Executive Order 12898 (Federal
Actions To Address Environmental
Justice in Minority Populations and
Low-Income Populations, 59 FR 7629,
February 16, 1994) directs Federal
agencies to identify and address
‘‘disproportionately high and adverse
human health or environmental effects’’
of their actions on minority populations
and low-income populations to the
greatest extent practicable and
permitted by law. EPA defines
environmental justice (EJ) as ‘‘the fair
treatment and meaningful involvement
of all people regardless of race, color,
national origin, or income with respect
to the development, implementation,
and enforcement of environmental laws,
regulations, and policies.’’ EPA further
defines the term fair treatment to mean
that ‘‘no group of people should bear a
disproportionate burden of
environmental harms and risks,
including those resulting from the
negative environmental consequences of
industrial, governmental, and
commercial operations or programs and
policies.’’
The Southwest Clean Air Agency did
not evaluate environmental justice
considerations as part of its SIP
submittal; the CAA and applicable
implementing regulations neither
prohibit nor require such an evaluation.
EPA did not perform an EJ analysis and
did not consider EJ in this action. Due

Consideration of EJ is not required as
part of this action, and there is no

SUPPLEMENTARY INFORMATION:
Executive Summary
Why we need to publish a rule. Under
the Act, when we determine that any
species is an endangered or threatened
species, we are required to designate
critical habitat, to the maximum extent
prudent and determinable. Designations
of critical habitat can be completed only
by issuing a rule through the
Administrative Procedure Act
rulemaking process (5 U.S.C. 551 et
seq.).
What this document does. We
propose to designate critical habitat for
the Sacramento Mountains checkerspot
butterfly, which is listed as an
endangered species under the Act.
The basis for our action. Under
section 4(a)(3) of the Act, if we
determine that a species is an
endangered or threatened species we
must, to the maximum extent prudent
and determinable, designate critical
habitat. Section 3(5)(A) of the Act
PO 00000
Frm 00016
Fmt 4702
Sfmt 4702
54263
defines critical habitat as (i) the specific
areas within the geographical area
occupied by the species, at the time it
is listed, on which are found those
physical or biological features (I)
essential to the conservation of the
species and (II) which may require
special management considerations or
protections; and (ii) specific areas
outside the geographical area occupied
by the species at the time it is listed,
upon a determination by the Secretary
that such areas are essential for the
conservation of the species. Section
4(b)(2) of the Act states that the
Secretary must make the designation on
the basis of the best scientific data
available and after taking into
consideration the economic impact, the
impact on national security, and any
other relevant impacts of specifying any
particular area as critical habitat.
Information Requested
We intend that any final action
resulting from this proposed rule will be
based on the best scientific and
commercial data available and be as
accurate and as effective as possible.
Therefore, we request comments or
information from other governmental
agencies, Native American Tribes, the
scientific community, industry, or any
other interested parties concerning this
proposed rule. We particularly seek
comments concerning:
(1) Specific information on:
(a) The amount and distribution of
Sacramento Mountains checkerspot
butterfly habitat;
(b) Any additional areas occurring
within the range of the species in Otero
County, New Mexico, that should be
included in the designation because
they (i) are occupied at the time of
listing and contain the physical or
biological features that are essential to
the conservation of the species and that
may require special management
considerations, or (ii) are unoccupied at
the time of listing and are essential for
the conservation of the species;
(c) Special management
considerations or protection that may be
needed in critical habitat areas we are
proposing, including managing for the
potential effects of climate change; and
(d) To evaluate the potential to
include areas not occupied at the time
of listing, we particularly seek
comments regarding whether occupied
areas are adequate for the conservation
of the species. Additionally, please
provide specific information regarding
whether or not unoccupied areas would,
with reasonable certainty, contribute to
the conservation of the species and
contain at least one physical or
biological feature essential to the

Emission Standards and Controls for Sources Emitting Gasoline Vapors
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) proposes to approve
a revision to the Washington State Implementation Plan (SIP) for the
Southwest Clean Air Agency (SWCAA) jurisdiction as it relates to the
ozone National Ambient Air Quality Standard. This proposed revision
updates SWCAA's requirements in the SIP for Stage I and Stage II vapor
recovery systems at gasoline dispensing facilities including:
decommissioning existing Stage II systems incompatible with onboard
refueling vapor recovery systems on or before January 1, 2023; allowing
removal from service of Stage II vapor recovery equipment compatible
with onboard refueling vapor recovery on or after January 1, 2023; and
removing the requirement for Stage II vapor recovery at new
installations. The proposed revisions to the SIP also include, among
other changes, revised requirements for installation of enhanced
conventional nozzles, installation of low permeation hoses, and annual
testing based on facility throughput. SWCAA's submittal, in
coordination with the Washington Department of Ecology, incudes a
demonstration that such removal of Stage II requirements is consistent
with the Clean Air Act and EPA guidance.

SUPPLEMENTARY INFORMATION: Throughout this document whenever ``we,''

I. Background
Ozone is a gas composed of three oxygen atoms. Ground-level ozone
is generally not emitted directly from a vehicle's exhaust or an
industrial smokestack but is created by a chemical reaction between
nitrogen oxides (NOX) and volatile organic compounds (VOC)
in the presence of sunlight and high ambient temperatures. VOC and
NOX emissions often are referred to as ``precursors'' to
ozone formation. Thus, ozone is known primarily as a summertime air
pollutant. Motor vehicle exhaust and industrial emissions, gasoline
vapors, chemical solvents and natural sources can emit or contain
NOX and/or VOC. Urban areas tend to have high concentrations
of ground-level ozone, but areas without
[[Page 54260]]
significant industrial activity and with relatively low vehicular
traffic are also subject to increased ozone levels because wind carries
ozone and its precursors hundreds of miles from their sources. In 1979,
under section 109 of the Clean Air Act (CAA or the Act), the EPA
established the primary and secondary National Ambient Air Quality
Standards (NAAQS) for ozone at 0.12 parts per million (ppm) averaged
over a 1-hour period (44 FR 8202, February 8, 1979). In 1997, we
revised the primary and secondary NAAQS for ozone to set the acceptable
level of ozone in the ambient air at 0.08 ppm, averaged over an 8-hour
period (62 FR 38856, July 18, 1997). In 2008, we further revised the
primary and secondary ozone NAAQS to 0.075 ppm, averaged over an 8-hour
period (73 FR 16436, March 27, 2008). In 2015, we again revised the
primary and secondary ozone NAAQS to 0.070 ppm, averaged over an 8-hour
period (73 FR 16436, March 27, 2008). For additional information on
ozone, visit https://www.epa.gov/ozone-pollution.
Stage II vapor recovery is an air pollution control technology for
automobiles and other on-road mobile sources. When an automobile or
other vehicle is brought into a gas station to be refueled, the empty
portion of the gas tank on the vehicle contains gasoline vapors, which
are VOCs. When liquid gasoline is pumped into the partially empty gas
tank in the vehicle the vapors are displaced out of the tank as the
tank fills with liquid gasoline. Where air pollution control technology
is not used, these vapors are emitted into the air. In the atmosphere,
these VOCs can, in the presence of sunlight, react with NOX
and VOCs from other sources to form ozone. The Stage II system consists
of special nozzles and coaxial hoses at each gas pump that capture
vapor from the vehicle's fuel tank and route them to underground or
above ground storage tanks during the refueling process. Stage II vapor
recovery systems are specifically installed at gasoline dispensing
facilities and capture the refueling fuel vapors at the gasoline pump
nozzle. The system directs the displaced vapors back to the underground
storage tank at the gasoline dispensing facility to prevent the vapors
from escaping to the atmosphere.
Onboard refueling vapor recovery (ORVR) is another emission control
system that can capture fuel vapors from vehicle gas tanks during
refueling. ORVR systems are carbon canisters installed directly on
automobiles to capture the fuel vapors displaced from the gasoline tank
before they are released to the atmosphere. The fuel vapors captured in
the carbon canisters are then combusted in the engine when the
automobile is started and operated after refueling.
Stage II vapor recovery systems and vehicle ORVR systems were
initially both required by the 1990 Amendments to the CAA, with Stage
II requirements applying to certain nonattainment areas. Under CAA
section 182(b)(3) ozone nonattainment areas classified as moderate and
above were required to adopt Stage II requirements. CAA section
202(a)(6), requires an onboard system of capturing vehicle refueling
emissions, commonly referred to as an ORVR system. In 1994, the EPA
promulgated ORVR standards (59 FR 16262, April 6, 1994). Section
202(a)(6) of the CAA required that the EPA's ORVR standards apply to
light-duty vehicles manufactured beginning in the fourth model year
after the model year in which the standards were promulgated, and that
ORVR systems provide a minimum evaporative emission capture efficiency
of 95 percent.\1\ ORVR equipment has been phased in for new light duty
vehicles (passenger vehicles) beginning with model year 1998 and
starting with model year 2001 for light-duty trucks and most heavy-duty
gasoline powered vehicles. Since 2006, ORVR has been a required
emissions control on nearly all new gasoline-powered highway vehicles
having less than 14,000 pounds gross vehicle weight rating. CAA section
202(a)(6) provides discretionary authority to the Administrator, by
rule, to revise or waive the application of the Stage II requirements
for areas classified as Serious, Severe, or Extreme for ozone, as
appropriate, after such time as the Administrator determines that
onboard emissions control systems are in widespread use throughout the
motor vehicle fleet.
---------------------------------------------------------------------------
\1\ Unlike Stage II, which is a requirement only in certain
ozone nonattainment areas, ORVR requirements apply to vehicles
everywhere.
---------------------------------------------------------------------------
On May 16, 2012, the EPA issued a national rulemaking making the
finding that ORVR systems are in ``widespread use'' and determined that
emission reductions from ORVR alone are essentially equal to and will
soon surpass the emission reductions achieved by Stage II alone (see 77
FR 28772 at 28772). In the May 16, 2012 action, we noted that each
year, non-ORVR-equipped vehicles continue to be replaced with ORVR-
equipped vehicles and Stage II and ORVR systems capture the same VOC
emissions and thus, are redundant. Id. The EPA also determined that
ORVR systems are in widespread use and waived the Stage II requirement
for gasoline dispensing facilities if doing so did not interfere with
attaining or maintaining the ozone standards. Id. at 28776-28779. The
EPA also noted that any state currently implementing Stage II vapor
recovery programs may submit SIP revisions that would allow for the
phase-out of Stage II vapor recovery systems including a CAA section
110(l) analysis showing that its removal did not interfere with
attaining or maintaining the ozone standards. Id.
The Portland/Vancouver area was designated an interstate ozone
nonattainment area in 1978. On November 15, 1990, the CAA Amendments of
1990 were enacted. (Pub. L. 101-549, 104 Stat. 2399, codified at 42
U.S.C. 7401-7671q). Under section 181(a)(1) of the 1990 CAA, the area
was further classified as a ``Marginal'' ozone nonattainment area. This
interstate nonattainment area consisted of the southern portion of
Clark County, Washington, and portions of Multnomah, Clackamas, and
Washington Counties in Oregon. In 1997, the EPA redesignated the
Portland/Vancouver area to attainment (62 FR 27204, May 19, 1997). The
Portland/Vancouver area was designated as ``unclassifiable/attainment''
due to the data showing the area was below the new NAAQS for subsequent
updates, including the 1997 8-hour ozone NAAQS (69 FR 23857, April 30,
2004), the 2008 8-hour ozone NAAQS (77 FR 30088, May 21, 2012), and the
2015 8-hour ozone NAAQS (82 FR 54232, November 16, 2017).
The Portland/Vancouver area was not subject to Stage II
requirements under the 1990 Clean Air Act Amendments as it was
classified as Marginal nonattainment for the 1-hour NAAQS for ozone,
rather than Moderate or above. However, SWCAA in coordination with the
Washington Department of Ecology submitted SWAPCA 491 ``Emission
Standards and Controls for Sources Emitting Gasoline Vapors'' (state
effective November 21, 1996, subsequently renamed to SWCAA 491) which
contained Stage II requirements as a SIP-strengthening measure approved
concurrently with redesignation of the Portland/Vancouver area to
attainment (see proposed rulemaking, 62 FR 10501, March 7, 1997, at
page 10507). On August 11, 2015 (80 FR 48033), the EPA approved SWCAA's
maintenance plan update for the Vancouver portion of the Portland/
Vancouver area that specifically anticipated and modeled widespread use
of ORVR and the full decommissioning of Stage II in the modeling
demonstration of continued attainment through 2015. The SWCAA
maintenance plan update and the
[[Page 54261]]
modeling demonstration are included in the docket for this action.
II. SWCAA's SIP Revision
On June 22, 2023, SWCAA, in coordination with the Washington
Department of Ecology as the Governor's designee for revisions to the
SIP, submitted the current version of SWCAA 491 ``Emission Standards
and Controls for Sources Emitting Gasoline Vapors'' (state effective
February 7, 2020) for EPA approval. Since the EPA's last approval of
SWCAA 491, SWCAA revised the regulations four times. Effective June 24,
2000, SWCAA updated the regulations to revise applicability of the
Stage II vapor recovery program, which is now replaced by the
applicability provisions of the current SWCAA 491. Other changes to
SWCAA 491, effective June 24, 2000, are generally SIP-strengthening in
nature including the addition of gasoline marine vessel loading and
unloading vapor control requirements, which are now contained in the
current version of SWCAA 491. The exact revisions in 2000 are in
redline/strikeout format included in the docket for this action under
WSR 00-11-149. Effective March 18, 2001 (WSR 01-05-067), SWCAA made
minor changes to SWCAA 491 to reflect the name change from ``Southwest
Pollution Control Authority'' to ``Southwest Clean Air Agency.''
Effective June 18, 2017 (WSR 17-11-080), SWCAA consolidated all agency
fees into a single location and updated the cross reference in SWCAA
491-030 accordingly. We note that the 2000, 2001, and 2017 revisions to
SWCAA 491 were not previously submitted as updates to the SIP. However,
to the extent these revisions are retained in the current version of
SWCAA 491 submitted for approval, we are proposing to determine that
these relatively minor changes since our last update to the SIP in 1997
are approvable.
The most substantive changes to SWCAA 491 since the EPA's last
approval are detailed in WSR 20-03-031, state effective February 7,
2020. Among other changes, this revision to SWCAA 491 included the
following: added a requirement to install enhanced conventional (ECO)
nozzles; added a requirement that low permeation hoses be installed on
higher volume gasoline dispensing facilities without balance type Stage
II vapor recovery equipment by no later than January 1, 2023; added a
requirement for annual testing of Stage I vapor recovery systems; \2\
added a requirement that new or upgraded gasoline storage tanks be
equipped with Stage I enhanced vapor recovery equipment; removed a
requirement that gasoline dispensing facilities install Stage II vapor
recovery equipment; allowed removal from service of Stage II vapor
recovery equipment compatible with ORVR on or after January 1, 2023;
allowed removal from service of Stage II vapor recovery equipment
incompatible with ORVR on or after January 3, 2020; required removal
from service of Stage II vapor recovery equipment incompatible with
ORVR no later than January 1, 2023; and revised the applicability
threshold for low flow nozzles to align SWCAA rules with Federal rules.
In the SIP submittal, SWCAA provided a demonstration that VOC emission
reductions from enhanced conventional nozzles and low permeation hoses
will outweigh the annual emissions impact of removing Stage II
requirements. Therefore, SWCAA requested removal of Stage II vapor
recovery system requirements in the SIP for SWCAA's jurisdiction.
---------------------------------------------------------------------------
\2\ Stage I vapor recovery is a system in which gasoline vapors
are forced from the storage tank into a vapor-tight gasoline tank
truck or vapor collection and control system through direct
displacement by the gasoline loaded into the storage tank.
---------------------------------------------------------------------------
III. The EPA's Evaluation of the Revision
The EPA's primary consideration for determining the approvability
of SWCAA's revisions to remove Stage II vapor control requirements and
provide for decommissioning of Stage II equipment within SWCAA's
jurisdiction is whether these revisions comply with section 110(l) of
the Act. Section 110(l) requires that a revision to the SIP not
interfere with any applicable requirement concerning attainment and
reasonable further progress (RFP), or any other applicable requirement
of the Act. The EPA can approve a SIP revision that removes or modifies
control measures in the SIP once the state or local agency makes a
``noninterference'' demonstration that such removal or modification
will not interfere with attainment of the NAAQS, RFP, or any other CAA
requirement.
The EPA reviewed SWCAA's submittal with the revised SWCAA 491
regulatory text as well as the accompanying analysis of emissions
impacts. We propose to determine that SWCAA's June 22, 2023, SIP
revision addresses the EPA's Widespread Use for Onboard Refueling Vapor
Recovery and Stage II Waiver (77 FR 28772) and is consistent with the
EPA's ``Guidance on Removing Stage II Gasoline Vapor Control Programs
from State Implementation Plans and Assessing Comparable Measures''
(EPA-457/B-12-001, August 7, 2012).\3\ In accordance with the EPA 2012
Guidance on Removing Stage II, SWCAA submitted a demonstration that the
Stage II decommissioning will not interfere with attainment or
maintenance of the ozone NAAQS. This demonstration was based on an
analysis of precursor VOC emissions from removal of Stage II controls
at GDFs, as well as emission reduction benefits from other changes to
the regulations such as requirements for enhanced conventional nozzles
and low permeation hoses. SWCAA estimated emissions impacts using the
guidance methodologies from the EPA 2012 Guidance showing an overall
benefit to air quality and a reduction of VOC emissions upon full
implementation of the rule requirements in 2023. SWCAA estimated the
impact on emissions from decommissioning Stage II in its jurisdiction
by using EPA approved equations from the same 2012 guidance, to assess
compliance with CAA 110(l). A detailed spreadsheet with the equation
calculations and supporting inputs is included in the docket for this
action.
---------------------------------------------------------------------------
\3\ The guidance document is available at: https://www3.epa.gov/ttn/naaqs/aqmguide/collection/cp2/20120807_page_stage2_removal_guidance.pdf.
---------------------------------------------------------------------------
The demonstration indicates that the emissions benefit of retaining
Stage II requirements is rapidly diminishing with vehicle fleet
turnover and ORVR penetration. As discussed in the EPA 2012 Guidance,
the EPA has developed equations to assist states in evaluating the
emissions consequences of phasing out existing Stage II programs. These
equations may be used to calculate an ``increment,'' which identifies
the area-wide emission control gained from Stage II installations as
ORVR technology phases in. For example, using the equations in the EPA
2012 Guidance, SWCAA calculated the increment declining from 4.0% in
2020 to 1.1% in 2023 for Clark County, the most populous county in
SWCAA's jurisdiction. Projecting these increments to full
implementation of the rule in 2023, the removal of Stage II vapor
recovery systems would result in minimal increases in VOC emissions of
18.31 tons per year (tpy) for SWCAA's entire jurisdiction.
Additionally, SWCAA calculated the emission reduction benefits of
enhanced conventional nozzles and low permeation hoses. These emission
reduction benefits are estimated to be 33.84 tpy, outweighing the
emissions increase from decommissioning Stage II
[[Page 54262]]
requirements. Overall, the 2020 regulatory changes are projected to
result in a net reduction of 15.99 tpy VOC with full implementation of
the rule. In addition, the EPA expects that market saturation of ORVR-
equipped vehicles will remain static or increase in the years after
2023, meaning the air quality benefits of these changes will continue
into the future.
Lastly, the removal of Stage II is consistent with the current
maintenance plan update for the Vancouver portion of the Portland/
Vancouver ozone area (80 FR 48033, August 11, 2015). As previously
discussed, this maintenance plan update was approved by the EPA in
2015. The associated modeling, included in the docket for this action,
anticipated the decommissioning of Stage II in the projection of
continued ozone attainment for the 1997 8-hour ozone NAAQS.\4\ For the
2008 and 2015 ozone NAAQS, all counties within SWCAA's jurisdiction are
designated attainment/unclassifiable. We believe that removal of Stage
II vapor recovery systems would have a negligible impact on ozone
levels which are offset by the emission reduction benefits of other
requirements in the revised SWCAA 491. Thus, we proposed to determine
that approval of the SIP revision would not interfere with any
applicable requirement concerning attainment and maintenance of any
ozone standard and is compliant with CAA section 110(l).

\4\ Consistent with EPA guidance, SWCAA evaluated compliance
with the 1997 8-hour ozone NAAQS because the former 1-hour ozone
NAAQS was replaced by the 1997 8-hour standard. See 62 FR 38856
(July 18, 1997) and 75 FR 24542 (May 5, 2010).
---------------------------------------------------------------------------
IV. Proposed Action
We are proposing to find that SWCAA's demonstration for removal of
Stage II equipment meets section 110(l) of the Act. Therefore, we are
proposing to approve and incorporate by reference SWCAA 491 ``Emission
Standards and Controls for Sources Emitting Gasoline Vapors'' state
effective February 7, 2020. This version of the regulation removes from
the Washington SIP the requirement for Stage II vapor recovery systems
in SWCAA's jurisdiction and adds additional VOC controls such as the
installation of enhanced conventional nozzles and low permeation hoses,
as well as other historic changes since the EPA's last approval as
discussed in section II of this preamble.
V. Incorporation by Reference
In this document, the EPA is proposing to include in a final rule,
regulatory text that includes incorporation by reference. In accordance
with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by
reference SWCAA 491 discussed in section IV of this preamble. The EPA
has made, and will continue to make, these documents generally
available through https://www.regulations.gov and at the EPA Region 10
Office (please contact the person identified in the FOR FURTHER
INFORMATION CONTACT section of this preamble for more information).
VI. Statutory and Executive Order Reviews
Under the Clean Air Act, the Administrator is required to approve a
SIP submission that complies with the provisions of the Clean Air Act
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 Clean Air Act.
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 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 14094 (88 FR 21879, April 11, 2023);
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 subject to Executive Order 13045 (62 FR 19885,
April 23, 1997) because it approves a state program;
Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001); and
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 Clean Air Act.
In addition, the SIP is not approved to apply on any Indian
reservation land or in any other area where EPA or an Indian tribe has
demonstrated that a tribe has jurisdiction. In those areas of Indian
country, the rule does not have tribal implications and will not impose
substantial direct costs on tribal governments or preempt tribal law as
specified by Executive Order 13175 (65 FR 67249, November 9, 2000).
Executive Order 12898 (Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations, 59 FR 7629,
February 16, 1994) directs Federal agencies to identify and address
``disproportionately high and adverse human health or environmental
effects'' of their actions on minority populations and low-income
populations to the greatest extent practicable and permitted by law.
EPA defines environmental justice (EJ) as ``the fair treatment and
meaningful involvement of all people regardless of race, color,
national origin, or income with respect to the development,
implementation, and enforcement of environmental laws, regulations, and
policies.'' EPA further defines the term fair treatment to mean that
``no group of people should bear a disproportionate burden of
environmental harms and risks, including those resulting from the
negative environmental consequences of industrial, governmental, and
commercial operations or programs and policies.''
The Southwest Clean Air Agency did not evaluate environmental
justice considerations as part of its SIP submittal; the CAA and
applicable implementing regulations neither prohibit nor require such
an evaluation. EPA did not perform an EJ analysis and did not consider
EJ in this action. Due to the nature of the action being taken here,
this action is expected to have a neutral to positive impact on the air
quality of the affected area. Consideration of EJ is not required as
part of this action, and there is no information in the record
inconsistent with the stated goal of E.O. 12898 of achieving
environmental justice for people of color, low-income populations, and
Indigenous peoples.
