40 CFR Part 52

[EPA-R10-OAR-2019-0574, FRL-8814-01-R10]


Approval and Promulgation of Air Quality Implementation Plans; 
Washington; Low Emission Vehicle Program

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve a revision to the Washington State Implementation Plan (SIP) 
pertaining to adoption by reference of a Low Emission Vehicle (LEV) 
program by the State of Washington. The Clean Air Act (CAA) grants 
authority to the EPA to adopt federal standards relating to the control 
of emissions from new motor vehicles, and generally preempts states 
from doing so. However, the CAA provides California the ability to 
adopt and enforce its own new motor vehicle emission standards, as long 
as the EPA approves California's standards via a preemption waiver. The 
CAA also allows other states to adopt California's new motor vehicle 
emission standards for which the EPA has granted such a waiver 
providing other relevant criteria are met. Washington adopted 
California's LEV emission standards in 2005, effective with new 
vehicles sold in model year 2009. Washington subsequently amended its 
new motor vehicle emissions program to incorporate California's LEV 
updates to its program. The purpose of this SIP revision is to 
implement programs to reduce vehicle emissions that contribute to 
formation of ground level ozone and fine particulate matter. Washington 
did not submit provisions related to greenhouse gas emissions from new 
motor vehicles or zero-emission vehicles requirements for inclusion in 
the SIP. The EPA is proposing to approve Washington's LEV SIP revision, 
as it relates to criteria pollutants, in accordance with the 
requirements of the CAA.

I. Background

A. What action is the EPA proposing?

    The EPA is proposing to approve a SIP revision submitted by 
Washington on September 30, 2019 requesting inclusion of the state's 
adopted and implemented California LEV standards as part of the 
Washington SIP. None of Washington's LEV rules are currently in the 
SIP. Under section 177 of the CAA, states with plan provisions approved 
under CAA part D (such attainment or maintenance plans for ozone and 
particulate matter described below) and other criteria in section 177 
are met, may adopt California's standards in lieu of otherwise 
applicable federal new motor vehicle emission standards.
    Washington's LEV rules are applicable to subject, new motor 
vehicles sold or titled in Washington beginning with model year 2009. 
Subject vehicles include passenger cars, light duty trucks, and medium 
duty passenger vehicles.\1\ Washington first adopted California LEV 
standards as state regulation, Chapter 173-423 Washington 
Administrative Code (WAC), in 2005 effective with the sale and titling 
of new vehicles beginning in model year 2009. Washington did not submit 
a request to the EPA to incorporate the program as a SIP revision at 
the time. However, to strengthen the SIP particularly with respect to 
ozone control, Washington formally submitted the state's LEV program 
regulations to the EPA on September 30, 2019 for approval and inclusion 
in the SIP. Further detail on Washington's LEV program is provided in 
section I.E. of this preamble. We are proposing to approve Washington's 
SIP revision because it will update the SIP with the current Washington 
LEV rules, and because such LEV rules satisfy the criteria under 
section 177 of the CAA.
---------------------------------------------------------------------------

    \1\ Effective June 11, 2020, the Washington State Legislature 
modified the LEV program to include all medium duty vehicles 
beginning with model year 2025 and adopted California's zero 
emission vehicle standards. See Revised Code of Washington 
70A.30.010. However, these recent statutory changes are not part of 
the 2019 rule package submitted for approval at this time.
---------------------------------------------------------------------------

B. Washington's Air Quality With Respect to the Federal National 
Ambient Air Quality Standards for Ozone and Fine Particulate Matter

1. Washington Ozone Attainment Status
    The CAA, as amended in 1990, requires the EPA to set National 
Ambient Air Quality Standards (NAAQS) for ambient air pollutants 
considered harmful to public health and the environment. The EPA 
establishes NAAQS for six principal air pollutants, or ``criteria'' 
pollutants, which include: Ozone, carbon monoxide, lead, nitrogen 
dioxide, particulate matter, and sulfur dioxide (SO2). The 
CAA establishes two types of NAAQS. Primary standards provide public 
health protection, including protecting the health of sensitive 
populations such as asthmatics, children, and the elderly. Secondary 
standards protect public welfare, including protection against 
decreased visibility and damage to animals, crops, vegetation, and 
buildings. The CAA also requires the EPA to periodically review the 
standards to ensure that they provide adequate health and environmental 
protection, and to update those standards as necessary.
    Ozone is formed in the atmosphere by photochemical reactions 
between ozone precursor pollutants, including volatile organic 
compounds (VOCs) and nitrogen oxides (NOX) in the presence 
of sunlight. In order to reduce ozone concentrations in the ambient 
air, the CAA directs areas designated as nonattainment to apply 
controls on VOC and NOX emission sources to reduce the 
formation of ozone.
    On November 6, 1991 (56 FR 56694), the EPA designated the Portland-
Vancouver area and the Seattle-Tacoma area as marginal nonattainment 
under the 1979 1-hour ozone NAAQS. For the 1-hour ozone NAAQS, 
attainment is defined when the expected number of days per calendar 
year, with maximum hourly average concentration greater than 0.12 parts 
per million (ppm) is equal to or less than 1. The EPA approved the 
state's CAA section 175A maintenance plan for the Portland-Vancouver 
area and redesignated the area to attainment on May 19, 1997 (62 FR 
27204). Similarly, the EPA approved the state's CAA section 175A 
maintenance plan for the Seattle-Tacoma area and redesignated the area 
to attainment on September 26, 1996 (61 FR 50438). The EPA later 
revoked the 1-hour ozone NAAQS effective June 15, 2005 (70 FR 44470).
    The EPA did not designate any nonattainment areas in Washington for 
subsequent updates to the ozone NAAQS, specifically designations for 
the 1997 8-hour ozone NAAQS (84 FR 23857, April 30, 2004), the 2008 
revision to the 8-hour ozone NAAQS (77 FR 30088, May 21, 2012), and the 
2015 revision to the 8-hour ozone NAAQS (82 FR 54232, November 16, 
2017). While there were no new ozone nonattainment areas designated in 
the state, Washington generally adopts pro-active measures to prevent 
nonattainment.
2. Washington Fine Particulate Matter Attainment Status
    Fine particulate matter (PM2.5) can be emitted directly 
or formed secondarily in the atmosphere. The main precursors of 
secondary PM2.5 are SO2, NOX, ammonia, 
and VOCs. Sulfates are a type of secondary particle formed from 
SO2 emissions of power plants and industrial facilities. 
Nitrates, another common type of secondary particle, are formed from 
NOX emissions of power plants, automobiles, and other 
combustion sources.
    On July 18, 1997, the EPA promulgated the first air quality 
standards for PM2.5 (62 FR 38652). The EPA promulgated 
primary and secondary annual standards at a level of 15 micrograms per 
cubic meter ([mu]g/m\3\),

[[Page 46171]]

based on a 3-year average of annual mean PM2.5 
concentrations. In the same rulemaking, EPA promulgated primary and 
secondary 24-hour standards of 65 [mu]g/m\3\, based on a 3-year average 
of the 98th percentile of 24-hour concentrations. All areas in 
Washington met the 1997 PM2.5 standards, with all counties 
classified as unclassifiable/attainment.
    On October 17, 2006 (71 FR 61144), the EPA revised the 
PM2.5 NAAQS, retaining the annual average NAAQS at 15 [mu]g/
m\3\ but revising the 24-hour NAAQS to 35 [mu]g/m\3\. On November 13, 
2009 (74 FR 58688), the EPA designated the Tacoma area as nonattainment 
for the 24-hour PM2.5 NAAQS. On February 10, 2015 (80 FR 
7347), the EPA approved the CAA section 175A maintenance plan for the 
Tacoma area and redesignated the area to attainment. Attainment was 
achieved primarily through wood stove emission reduction measures. 
However, projected declines in mobile source precursor emissions from 
ongoing vehicle fleet turnover also played a role in demonstrating 
continued attainment of the NAAQS.
    Lastly, on January 15, 2013, the EPA promulgated a revised primary 
annual PM2.5 NAAQS (78 FR 3086), strengthening the standard 
from 15 [micro]g/m\3\ to 12 [micro]g/m\3\. Nonattainment area 
designations for the 2012 primary annual PM2.5 standard were 
published on January 15, 2015 (80 FR 2206), with all counties in 
Washington classified as unclassifiable/attainment.

C. Federal Motor Vehicle Emission Standards

    To reduce air pollution from motor vehicles, which contribute to 
higher levels of ambient air pollution such as ozone and 
PM2.5, motor vehicles sold in the United States are required 
by the CAA to be certified to meet federal motor vehicle emission 
standards. States are generally prohibited from adopting vehicle 
standards, except for California, which was granted an exception by the 
CAA to continue to issue its own vehicle emission standards. Section 
209 of the CAA requires that, among other criteria for a waiver of 
preemption, California must demonstrate to the EPA that its newly 
adopted standards will be in the aggregate, at least as protective of 
public health and welfare as applicable federal standards.
    The CAA also authorizes other states to adopt California emission 
standards for which the EPA has granted California such a waiver of 
preemption. Under section 177 of the CAA, states with CAA part D 
attainment or maintenance plans are authorized to adopt California's 
standards in lieu of federal vehicle standards, provided they do so 
with at least two model years lead time prior to the effective date of 
the standards, and provided that the EPA has issued a waiver of 
preemption to California for such standards.

D. California LEV Program

    In 1990, California's Air Resources Board (CARB) adopted LEV 
standards applicable to light and medium duty vehicles and phased in 
beginning with model year 1994 vehicles. In 1999, California adopted a 
second generation of LEV standards, known as LEV II, which were phased 
in beginning model year 2004. The EPA waived federal preemption for 
California's LEV II program on April 22, 2003 (68 FR 19811).
    In 2012, California approved a new, more stringent LEV program 
called the Advanced Clean Cars Program, or the LEV III program. 
California codified the LEV III requirements for criteria pollutant 
control in Title 13 of the California Code of Regulations, Division 3, 
section 1961.2. The program was phased in beginning with vehicles 
certified in model year 2015 and applied to light duty vehicles, light 
duty trucks, and medium duty passenger vehicles. On June 9, 2013 (78 FR 
2112), the EPA granted a federal preemption waiver for California's 
Advanced Clean Cars Program.\2\
---------------------------------------------------------------------------

    \2\ We note that California's LEV III requirements for 
greenhouse gas exhaust emission standards codified in sections 
1961.1 and 1961.3 were not submitted for approval as part of 
Washington's adoption by reference of the California LEV rules, nor 
were provisions related to zero emission vehicles (ZEV).
---------------------------------------------------------------------------

E. Washington LEV Program

    In 2005, the Washington Legislature first adopted California's LEV 
program under Revised Code of Washington (RCW) 70A.30.010. Washington's 
adoption in 2005 applied to passenger cars, light duty trucks, and 
medium duty passenger vehicles, excluding other medium duty vehicles 
and California's ZEV requirements.\3\ The legislature directed the 
Washington Department of Ecology (Ecology) to develop regulations 
implementing the adoption of California's LEV program, which Ecology 
codified in Chapter 173-423 Washington Administrative Code (WAC). 
Chapter 173-423 WAC became effective December 31, 2005 and applied to 
all 2009 and subsequent model years.\4\ However, Washington did not 
submit the 2005 version of its LEV program regulations as a SIP 
revision request to EPA at that time. Ecology subsequently amended its 
LEV program regulations to incorporate by reference updates to the 
applicable California's LEV program requirements codified in California 
Code of Regulations Title 13, Division 3.\5\
---------------------------------------------------------------------------

    \3\ Effective June 11, 2020, the Washington State Legislature 
modified the LEV program to include all medium duty vehicles 
beginning with model year 2025 and adopted California's zero 
emission vehicle standards. However, these recent statutory changes 
are not part of the 2019 rule package submitted for approval at this 
time.
    \4\ See Washington State Register (WSR) 05-24-044 included in 
the docket for this action.
    \5\ See WSR 09-03-077, 12-24-033, 16-12-099, and 19-02-056 
included in the docket.
---------------------------------------------------------------------------

II. Summary of the September 2019 Washington LEV SIP Revision

    On September 30, 2019, Washington submitted a SIP revision 
requesting that the EPA amend the SIP to incorporate the state LEV 
requirements under Chapter 173-423 WAC. Washington's LEV program 
includes California's LEV III standards for criteria pollutant control, 
which Ecology first incorporated by reference on November 28, 2012, 
effective December 29, 2012.\6\ Under section 177 of the CAA, states 
with CAA Part D attainment or maintenance plans, such as Washington, 
may adopt California's standards in lieu of federal vehicle standards, 
provided they do so with at least two model years lead time prior to 
the effective date of the standards, and provided that the EPA has 
issued a waiver of preemption to California for such standards. As 
noted above, Washington adopted the California LEV standards in 2005 
applying to model year 2009 vehicles, meeting the two-year lead time 
requirement under section 177 of the CAA. As discussed above, the 
California LEV II standards adopted by Washington in 2005 had already 
received an EPA federal preemption waiver in 2003. Therefore, 
Washington met all CAA section 177 requirements for initial adoption of 
the California LEV standards. Subsequent updates, such as adoption of 
California's LEV III, which also received a federal preemption waiver, 
also met the two-model year lead time requirement. Since the adoption 
of California's LEV III program in 2012, there have been no major 
changes to Washington's LEV program for criteria pollutants; however, 
Ecology has periodically updated the incorporation by reference in 
Chapter 173-423 WAC to maintain consistency with the California motor 
vehicle emission standards.
---------------------------------------------------------------------------

    \6\ See WSR 12-24-033 included in the docket.
---------------------------------------------------------------------------

    Washington submitted, and the EPA is proposing to approve and 
incorporate by reference into the SIP, Chapter 173-

[[Page 46172]]

423 Low Emission Vehicles with one important caveat. Washington did not 
submit provisions related to California's greenhouse gas motor vehicle 
emission standards.\7\ A strikeout version of Chapter 173-423 WAC with 
the greenhouse gas provisions excluded from our proposed approval is 
included in the docket for this action.\8\ These exclusions are also 
noted in the table of regulations proposed for approval in section III. 
of this preamble. Lastly, as discussed in section I.E. of this 
preamble, Chapter 173-423 WAC does not include California's zero 
emission vehicle requirements.\9\
---------------------------------------------------------------------------

    \7\ See National Ambient Air Quality Standards: Infrastructure 
State Implementation Plan for 2015 Ozone and 2010 Sulfur Dioxide, 
Appendix B.
    \8\ See 301_proposed IBR_Chapter 173-423 WAC_strike through.pdf.
    \9\ On May 10, 2021, Ecology announced intent to start 
rulemaking to revise Chapter 173-423 WAC to include zero emission 
vehicles for passenger cars, light duty trucks, and medium duty 
vehicles; zero emission vehicles for medium and heavy duty trucks 
(Advanced Clean Trucks); and low emission vehicle requirements for 
medium duty vehicles.
---------------------------------------------------------------------------

III. The EPA's Proposed Action

    As previously noted, under section 177 of the CAA, states with CAA 
part D attainment or maintenance plans, such as Washington, are 
authorized to adopt California's standards in lieu of federal vehicle 
standards. Washington first adopted the California standards effective 
December 31, 2005; however, the state did not submit the LEV rules for 
approval in the SIP at the time. In 2019, Washington submitted the LEV 
rules to strengthen the SIP with respect to ozone control statewide, 
including current maintenance areas.\10\ We are proposing to approve 
Washington's request because it meets the requirements of section 177 
of the CAA. Specifically, the EPA is proposing to approve and 
incorporate by reference into the Washington SIP at 40 CFR 52.2470(c), 
Table 1--Regulations Approved Statewide, the regulations listed in the 
table below.

IV. 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 the regulations shown in section III 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).

V. 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 Act and 
applicable federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). 
Thus, in reviewing SIP submissions, the EPA's role is to approve state 
choices, provided that they meet the criteria of the Clean Air Act. 
Accordingly, this proposed 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);
     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);

[[Page 46173]]

     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 the requirements would be inconsistent 
with the Clean Air Act; and
     Does not provide the 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).
    The SIP is not approved to apply on any Indian reservation land in 
Washington except as specifically noted below and is also not approved 
to apply in any other area where the EPA or an Indian tribe has 
demonstrated that a tribe has jurisdiction. In those areas of Indian 
country, the proposed 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). Washington's SIP is approved to apply on non-trust land 
within the exterior boundaries of the Puyallup Indian Reservation, also 
known as the 1873 Survey Area. Under the Puyallup Tribe of Indians 
Settlement Act of 1989, 25 U.S.C. 1773, Congress explicitly provided 
state and local agencies in Washington authority over activities on
