I. Background
On March 12, 2008, the EPA revised both the primary and secondary
NAAQS for ozone to a level of 0.075 parts per million (ppm) to provide
increased protection of public health and the environment (73 FR 16436,
March 27, 2008).\1\ The 2008 ozone NAAQS retains the same general form
and averaging time as the 0.08 ppm NAAQS set in 1997 but is set at a
more protective level. Specifically, the 2008 ozone NAAQS is attained
when the 3-year average of the annual fourth-highest daily maximum 8-
hour average ambient air quality ozone concentrations is less
[[Page 11914]]
than or equal to 0.075 ppm. See 40 CFR 50.15.\2\
---------------------------------------------------------------------------
\1\ For a history of the ozone NAAQS, please visit https://www.epa.gov/ground-level-ozone-pollution/table-historical-ozone-national-ambient-air-quality-standards-naaqs. For information on
EPA's periodic review of the ozone NAAQS, please visit https://www.epa.gov/naaqs/ozone-o3-air-quality-standards.
\2\ The current NAAQS for ozone is an 8-hour standard of 0.070
ppm, finalized in 2015 (October 26, 2015, 80 FR 65292). This action
does not address the 2015 ozone NAAQS.
---------------------------------------------------------------------------
Both the DFW and HGB areas were designated as nonattainment for the
2008 ozone NAAQS (77 FR 30088, May 21, 2012). The DFW area consists of
Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall,
Tarrant and Wise counties. The HGB area consists of Brazoria, Chambers,
Fort Bend, Galveston, Harris, Liberty, Montgomery and Waller counties.
On December 23, 2014, the D.C. Circuit Court issued a decision
rejecting, among other things, our attainment deadlines for the 2008
ozone nonattainment areas, finding that we did not have statutory
authority under the CAA to extend those deadlines to the end of the
calendar year. NRDC v. EPA, 777 F.3d 456, 464-69 (D.C. Cir. 2014).
Consistent with the court's decision we modified the attainment
deadlines for all nonattainment areas for the 2008 ozone NAAQS, and set
the attainment deadline for all 2008 moderate ozone nonattainment
areas, including the DFW area as July 20, 2018, and the HGB area
(initially classified as marginal) as July 20, 2015 (80 FR 12264, March
6, 2015). The HGB area qualified for a 1-year extension of the
attainment deadline and we revised the attainment deadline to July 20,
2016 (81 FR 26697, May 4, 2016). The HGB area did not meet the revised
attainment deadline of July 20, 2016, and we reclassified the area to
moderate (81 FR 90207, December 14, 2016). The DFW and HGB areas did
not meet the moderate area attainment deadline and were accordingly
reclassified as serious (84 FR 44238, August 23, 2019).\3\ Section 182
of the CAA outlines SIP requirements applicable to ozone nonattainment
areas in each classification category. The serious area classification
triggers additional requirements, including NNSR and enhanced vehicle
I/M. See CAA section 182(c) and 40 CFR 51.350.
---------------------------------------------------------------------------
\3\ The attainment deadline for a serious area classification is
9 years after the initial designation as nonattainment, which in
this case is July 20, 2021. See 40 CFR 51.1103 and 84 FR 44238.
---------------------------------------------------------------------------
On May 13, 2020, the Texas Commission on Environment Quality (TCEQ
or State) submitted to EPA a SIP revision for each of the DFW and HGB
serious ozone nonattainment areas. In those SIP revisions, the State
describes how the DFW and HGB areas meet the enhanced vehicle I/M
program and NNSR requirements for serious ozone nonattainment areas
using existing measures already approved into the SIP. These two SIP
revisions are available in the docket for this action, at
www.regulations.gov, docket number EPA-R06-OAR-2020-0343.
II. The TCEQ Submittals and EPA's Evaluation
The two Texas SIP revisions include a statement certifying that the
DFW and HGB areas meet the serious area requirements for enhanced I/M
and nonattainment NSR for the 2008 eight-hour ozone NAAQS. In addition,
the SIP revisions provide a brief history of the enhanced I/M and NNSR
programs in the Texas SIP. The SIP revisions also state that, (1) the
vehicle I/M program in the DFW and HGB ozone nonattainment areas meet
the federal requirements for areas classified as serious or above; and
(2) because the Texas SIP includes nonattainment NSR requirements, the
requirements for nonattainment NSR are met for the DFW and HGB serious
ozone nonattainment areas.
Enhanced Vehicle Inspection and Maintenance
Section 182(c)(3) of the CAA requires states with ozone
nonattainment areas classified as serious or worse to implement an
enhanced program to reduce hydrocarbon emissions and nitrogen oxides
(NOX) \4\ emissions from in-use motor vehicles registered in
each urbanized area in the nonattainment area. The Federal rules
addressing I/M program requirements are provided at 40 CFR part 51,
subpart S and further defined at 40 CFR 51.350 (Applicability). Under
these requirements, serious ozone nonattainment areas in urbanized
areas with 1980 Census-defined urbanized populations of 200,000 or more
are required to adopt enhanced I/M programs (40 CFR 51.350(a)(2) and
(4)).
---------------------------------------------------------------------------
\4\ NOX and Volatile Organic Compounds (VOC) are
precursors to ozone formation.
---------------------------------------------------------------------------
The Texas SIP includes 30 TAC Section 114.2 (Inspection and
Maintenance Definitions) and 30 TAC Section 114.50 (Vehicle Emissions
Inspection Requirements) except for 30 TAC Section 114.50(b)(2).\5\
Under these provisions Brazoria, Fort Bend, Galveston, Harris, and
Montgomery counties in the HGB area are included in the I/M program,
and Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall,
and Tarrant counties in the DFW area are included in the I/M program.
The program requires that gasoline powered light-duty vehicles, and
light and heavy-duty trucks between two and twenty-four years old, that
are registered or required to be registered in the I/M program area,
including fleets, are subject to annual inspection and testing. These
programs were adopted and approved as meeting the applicable
requirements of the I/M rules in response to the area designations
under the one-hour ozone standard and later the 1997 8-hour standard.
The size of the HGB nonattainment area did not change with the
implementation of the 2008 ozone standard. As a result, EPA's previous
finding that the program covers the necessary vehicle population is
still appropriate. See 70 FR 58119, 58132 (October 5, 2005) and 71 FR
52670 (September 6, 2006). Wise County was added to the DFW
nonattainment area under the 2008 standard. Wise County, however, is
not required to be included in the I/M program as the current I/M
program in the DFW area sufficiently covers a non-urbanized area
population greater than the urbanized area in Wise County. To verify,
we evaluate the extent of area coverage for I/M, as defined at 40 CFR
51.350(b)(2): ``Outside of ozone transport regions, programs shall
nominally cover at least the entire urbanized area, based on the 1990
census.\6\ Exclusion of some urban population is allowed as long as an
equal number of non-urban residents of the MSA containing the subject
urbanized area are included to compensate for the exclusion.'' Based on
the 1990 census, the urban population of the DFW area covered by the I/
M program (which consisted of 9 counties: Collin, Dallas, Denton,
Ellis, Johnson, Kaufman, Parker, Rockwall and Tarrant) was 3,198,259
and the urban population of Wise County was 8,735. Thus, the population
of the entire urbanized area was 3,206,994 (3,198,259 + 8,735). The
urban and non-urban population of the 9-county DFW area was 3,885,415.
By subtracting the population of the entire urbanized area (3,206,994)
from the urban and non-urban populations of the 9-county DFW I/M area
(3,885,415-3,206,994 = 678,421), more than an equal number of non-urban
residents in the 9-county DFW area are included in the I/M
[[Page 11915]]
program to compensate for the exclusion of the urbanized population of
8,735 in Wise County.\7\ Thus, Wise County need not implement an I/M
program.
---------------------------------------------------------------------------
\5\ We did not approve 30 TAC Section 114.50(b)(2) as part of
the Texas SIP as (1) it placed an additional reporting burden upon
commanders at Federal facilities regarding affected Federal vehicles
that is not imposed upon any other affected non-federal vehicle; and
(2) the additional reporting requirement is not an essential element
for an approvable I/M program, since affected Federal vehicles are
also subject to the same reporting requirements as other affected
non-federal vehicles. See 66 FR 57261, 57262 (November 14, 2001).
\6\ Texas is not included in the Ozone Transport Region (OTR),
which is defined at CAA section 184(a).
\7\ All population data in this paragraph are from the 1990
Census. The 1990 Census report for Texas is in the docket for this
rulemaking.
---------------------------------------------------------------------------
Therefore, since the provisions in the Texas SIP already include
the I/M requirements specified by the CAA for serious ozone
nonattainment areas, we are proposing to approve this portion of the
two SIP revisions.
Nonattainment NSR
The applicable NNSR requirements for the various ozone
nonattainment classifications are described in CAA section 182 and
further defined in 40 CFR part 51, subpart I (Review of New Sources and
Modifications). Under these requirements new major sources or major
modifications at existing sources in an ozone nonattainment area must
comply with the lowest achievable emission rate and obtain sufficient
emission offsets.\8\ For serious ozone nonattainment areas, major
sources are defined as any stationary source or group of sources
located within a contiguous area and under common control that emits,
or has the potential to emit, at least 50 tons per year (tpy) of
NOX or VOC (see CAA sections 182(c) and 182(f), and 40 CFR
51.165). The emission offset ratio required for serious ozone
nonattainment areas is 1.2 to 1 (see CAA section 182(c)(10).
---------------------------------------------------------------------------
\8\ Offsets are the ratio of total emissions reductions of
NOX or VOC to the emissions increase of such air
pollutant.
---------------------------------------------------------------------------
The EPA-approved Texas SIP already includes 30 TAC Section 116.12
(Nonattainment and Prevention of Significant Deterioration Review
Definitions) and 30 TAC Section 116.150 (New Major Source or Major
Modification in Ozone Nonattainment Area).\9\ These provisions require
new major sources or major modifications at existing sources in the DFW
and HGB areas to comply with the lowest achievable emission rate and
obtain emission offsets at the serious classification ratio of 1.2 to
1.
---------------------------------------------------------------------------
\9\ See 60 FR 49781, September 27, 1995 and subsequent revisions
at 77 FR 65119, October 25, 2012 and 79 FR 66626, November 10, 2014.
---------------------------------------------------------------------------
Therefore, since the provisions in the Texas SIP already include
the NNSR requirements specified by the CAA for serious ozone
nonattainment areas, we are proposing to approve this portion of the
two SIP revisions.
III. Proposed Action
We are proposing to approve portions of two revisions to the Texas
SIP submitted on May 13, 2020, that describe how CAA requirements for
vehicle I/M and NNSR are met in the DFW and HGB serious ozone
nonattainment areas for the 2008 ozone NAAQS.
IV. Statutory and Executive Order Reviews
Under the CAA, 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 CAA. Accordingly, this
action merely proposes to approve 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 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);
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, 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 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).
