ACTION: Final rule. AGENCY: Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is approving a revision to the Texas State Implementation Plan (SIP) to meet the Reasonable Further Progress (RFP) requirements for the HoustonGalveston-Brazoria (HGB) moderate 2008 8-hour ozone nonattainment area (HGB area). EPA is approving the RFP demonstration, contingency measures, motor vehicle emissions budgets (MVEBs) and an updated 2011 base year emissions inventory. DATES: This rule is effective on March 15, 2019. ADDRESSES: The EPA has established a docket for this action under Docket ID No. EPA–R06–OAR–2017–0056.

SUMMARY: Ms. Wendy Jacques, 214–665–7395, jacques.wendy@epa.gov. SUPPLEMENTARY INFORMATION: Throughout this document ‘‘we,’’ ‘‘us,’’ and ‘‘our’’ means the EPA. FOR FURTHER INFORMATION CONTACT: ENVIRONMENTAL PROTECTION AGENCY I. Background The background for this action is discussed in detail in our April 25, 2018 proposal (83 FR 17964). In that document we proposed to approve the RFP demonstration, contingency measures, MVEBs and an updated 2011 base year emissions inventory for the HGB area. We received comments of support on the proposal from the Texas Commission on Environmental Quality and two relevant adverse comments from Environmental Integrity Project. Our response to the adverse comments are below. II. Response to Comments Comment: Environmental Integrity Project commented that (1) it is unclear whether episodic emissions of ozone forming pollutants resulting from unplanned startups, shutdowns, maintenance, upsets and other unauthorized emissions are included in the Emissions Inventory ozone season daily nitrogen oxide (NOX) and volatile organic compound (VOC) values upon which the RFP plan is based and (2) to the extent that these values used to develop the baseline and future year emissions inventories do not include episodic emissions the RFP plan fails as a matter of law because the emissions inventories fail to include all actual emissions. The commenter notes that these emissions are quantifiable since companies report these episodic emissions to be included in TCEQ’s emission inventory. The commenter also noted that researchers in the past have confirmed that these episodic emissions are important as they can sometimes result in large increases of ozone and are significant to the ozone problem in Houston and not including these episodic emissions in the RFP is erroneous. The commenter states that the RFP SIP must include a ‘‘comprehensive, accurate, current inventory of actual emissions from all sources.’’ Response: CAA section 182(a)(1) requires states with ozone nonattainment areas to submit a SIP revision with a comprehensive, accurate, current inventory of actual emissions from all sources in an ozone nonattainment area in accordance with guidance provided by the Administrator. CAA section 182(b)(1) requires ozone nonattainment areas classified as Moderate and above to submit a RFP SIP revision. To implement CAA emissions inventory requirements for the 2008 ozone NAAQS we promulgated ‘‘Emissions inventory requirements’’ at 40 CFR 51.1115. The emissions values are required to be an average day’s emissions for a typical ozone season work weekday (40 CFR 51.1115(c) and 40 CFR 51.1100(cc)). To implement the RFP requirements for the 2008 ozone NAAQS we promulgated ‘‘Requirements for reasonable further progress’’ at 40 CFR 51.1110. The values of the base year emissions inventory for RFP plans are to be an average day’s emissions for a typical ozone season work weekday (40 CFR 51.1110(b) and 40 CFR 51.1100(cc)). Texas submitted a 2011 base year emissions inventory SIP revision for the HGB area on July 16, 2014 and we approved it as meeting the emissions inventory requirements for the 2008 ozone standard on February 20, 2015 (80 FR 9204). The RFP demonstration updated the previously approved emissions inventory with better estimates of an average day’s emissions for a typical ozone season work weekday. A summary of the update to the 2011 base year emissions inventory is found in table 1.

EPA’s emission inventory guidance recommends including Startup, Shutdown, and Maintenance emissions in the RFP baseline and future year weekday ozone season day emission inventory values if the emissions can be reasonably and sufficiently quantified with regular and predictable emissions.1 Similarly, Texas emission inventory guidance is to include all authorized/planned 2 Startup, Shutdown and Maintenance emissions in the ozone season day emissions reported in annual emission inventories submitted by sources that are used by TCEQ for the RFP baseline and future year RFP inventories.3 In their RFP SIP, TCEQ included authorized/planned Start-up, Shutdown, and Maintenance (SSM) emissions from 2011 in their 2011 baseline inventory and also included authorized/planned emissions that occurred in 2014 in the 2014 inventory that they used to project the 2017 future RFP inventory. Since the amount and magnitude of authorized/planned events varies from day to day, Texas includes the average value of these emissions in the RFP average weekday inventory.4 So, Texas does include an estimate of authorized/planned Start-up, Shutdown, and Maintenance emissions. Texas does not include unplanned startups, shutdowns, maintenance, upsets and other unauthorized emissions in their RFP inventories. This is consistent with EPA’s guidance which states;5 ‘‘Since malfunctions are, 1 ‘‘Emissions Inventory Guidance for Implementation of Ozone and Particulate Matter National Ambient Air Quality Standards (NAAQS) and Regional Haze Regulations’’; EPA–454/B–17– 003, July 2017; pages 79–80. And ‘‘Emissions Inventory Guidance for Implementation of Ozone and Particulate Matter National Ambient Air Quality Standards (NAAQS) and Regional Haze Regulations’’, EPA–454/B–17–003; July 2017, page 19, Section 2.5.2. 2 The commenter discussed unplanned and unauthorized emissions and TCEQ guidance centers around authorized and non-authorized and does not use the unplanned/planned language. For this Response to Comment we are interpreting that the commenter was equating planned with authorized and unplanned with non-authorized. 3 TCEQ RG–360A/11 ‘‘2011 Emission Inventory Guidelines’’ pages 65–70 and TCEQ RG–360A/14, ‘‘2014 Emission Inventory Guidelines’’ pages 70–72. 4 Texas receives data on the hours that the emissions occurred for each occurrence and then totals the emissions during ozone season and divides by the total number of hours that these types of emissions occurred to yield an average emission rate (lb/hr that is translated to OSD) that is included in the RFP inventories. 5 ‘‘Emissions Inventory Guidance for Implementation of Ozone and Particulate Matter National Ambient Air Quality Standards (NAAQS) and Regional Haze Regulations’’; EPA–454/B–17– 003, July 2017; page 80. VerDate Sep<11>2014 16:46 Feb 12, 2019 Jkt 247001 by nature, unpredictable and given the myriad different types of malfunctions that can occur, malfunction emissions would be difficult to estimate and future-year malfunction events cannot be readily predicted. Thus, states are not obligated to include malfunction emissions in the base inventory for the NAA, ROP/RFP plans, or attainment projected inventory for the NAA. However, to the extent that malfunctions become a regular and predictable event, then such emissions should be quantified with regular and predictable emissions and included in emission inventories for planning purposes. The elimination of high emissions during routinely reoccurring malfunctions could potentially help achieve significant emissions reductions needed by a state in attaining the relevant NAAQS.’’ Malfunctions in EPA’s terminology are very similar to unplanned events in TCEQ’s regulatory structure. Because of the unpredictability and variability of unplanned and/or unauthorized emissions due to malfunctions, as explained in the EPA guidance it is reasonable that Texas did not include these emissions in its estimate of average ozone season weekday emissions. Although these unauthorized emissions are not appropriate to be included in the RFP plan, TCEQ recognizes the importance of emissions from startups, shutdowns, maintenance, and upsets/malfunctions. These episodic emissions (planned and unplanned) are quantified and included in the attainment demonstration modeling which better lends itself for utilization of day to day variation of emissions because daily emissions from specific historic episodes are modeled versus typical ozone season day weekday emissions used in the RFP inventories.6 Furthermore, based on the evolving knowledge about unplanned episodic emissions and the potential impacts on ozone levels, TCEQ has conducted a number of studies that have resulted in best management practice improvements for some point source categories to reduce episodic emission events.7 For example, TCEQ’s studies 6 EPA–R06–OAR–2017–0053–0004; ‘‘Appendix B: Emissions Modeling for the HGB Attainment Demonstration sip Revision for the 2008 Eight-Hour Ozone Standard’’ 7 For a discussion of the studies please see pages 248–251 of the Technical Support Document for the Houston Galveston Brazoria Modeling and Other Analyses Attainment Demonstration (HGB– MOAAD) at https://www.regulations.gov/ document?D=EPA-R06-OAR-2013-0387-0002. Also see documents available at https:// www.tceq.texas.gov/airquality/stationary-rules/ stakeholder/flare_stakeholder.html. PO 00000 Frm 00041 Fmt 4700 Sfmt 4700 3709 have included best management practice improvements for flaring, which is one of the sources related with malfunctions and that may have the potential to impact ozone levels. These best management practice improvements are expected to result in emission reductions, but EPA acknowledges that quantification of baseline and future year emission events and non-authorized/unplanned start-up, shutdown, and maintenance emissions (future year would be expected to be different than baseline) with the certainty required for a RFP SIP is not reasonably possible. In sum, Texas’s approach is consistent with our emissions inventory guidance regarding non-authorized/unplanned episodic/malfunction emissions. EPA believes these emissions can vary significantly and unpredictably from day to day and therefore it is acceptable these emissions not be included in the periodic emissions inventory required under 40 CFR 51.1115(b) or the emissions inventory for RFP purposes. We note Texas recognizes the importance of these emissions and has undertaken efforts to reduce episodic emissions. In conclusion, TCEQ has met the requirements of 40 CFR 51.1110, 40 CFR 51.1115 and sections 182(a)(1) and 182(b)(1) of the CAA. Comment: Environmental Integrity Project also stated that we may not rely on motor vehicle emissions reductions that we intend to discontinue. The comment stated that the single largest anticipated vehicle emissions reduction is from the Federal Motor Vehicle Control Program (FMVCP) and referred to an April announcement that we would work with the National Highway Traffic Safety Administration to revise the greenhouse gas (GHG) emissions standards and Corporate Average Fuel Economy (CAFE) standards for model year 2022 and 2025 light-duty vehicles. Response: EPA agrees that SIPs can only rely upon reductions that are enforceable for the purpose and years addressed by the SIP. However, it is incorrect that the RFP SIP relies on motor vehicle emissions reductions that we intend to discontinue. The RFP SIP addresses NOx and VOC emission levels for the year 2011 to 2018, and during that time period the SIP relies on NOx and VOC emission reductions that have already occurred. In the case of the contingency measure reductions, these are expected to occur in 2018 due to regulations that have been implemented. In addition, it is important to note that the SIP relies upon EPA’s emissions standard regulations which reduce criteria pollutant emissions. The GHG E:\FR\FM\13FER1.SGM 13FER1 3710 Federal Register / Vol. 84, No. 30 / Wednesday, February 13, 2019 / Rules and Regulations regulations cited by the commenter do not affect criteria pollutant emissions standards and are also not related to the years addressed by the SIP. III. Final Action We are approving the HGB RFP SIP revision submitted on December 29, 2016, to meet the RFP requirements for the HGB moderate 2008 8-hour ozone nonattainment area as well as an updated 2011 base year emissions inventory for the 2008 Ozone NAAQS. This action is being taken under section 110 of the Act. 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 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 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, 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). The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this action and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This action is not a ‘‘major rule’’ as defined by 5 U.S.C. 804(2). Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by April 15, 2019. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)

ACTION: Final rule. AGENCY: The Environmental Protection Agency (EPA) is approving a revision to the Indiana State Implementation Plan (SIP) to meet the base year emissions inventory, reasonable further progress (RFP), RFP contingency measure, nonattainment new source review (nonattainment NSR), volatile organic compound (VOC) reasonably available control technology (RACT), and motor vehicle inspection and maintenance (I/ M) requirements of the Clean Air Act (CAA) for the Indiana portion of the Chicago-Naperville, Illinois-IndianaWisconsin area (Chicago area) for the 2008 ozone national ambient air quality standard (NAAQS or standard). EPA is also approving the 2017 transportation conformity motor vehicle emissions budgets (MVEBs) for the Indiana portion of the Chicago area for the 2008 ozone NAAQS. EPA is approving the state’s submission as a SIP revision pursuant to section 110 and part D of the CAA and EPA’s regulations because it satisfies the emission inventory, RFP, RFP contingency measure, nonattainment NSR, VOC RACT, I/M, and transportation conformity requirements for areas classified as moderate nonattainment for the 2008 ozone NAAQS. This final action permanently stops the Federal Implementation Plan (FIP) clock triggered by EPA’s February 3, 2017 finding that Indiana failed to submit a marginal ozone nonattainment NSR plan. EPA proposed to approve these provisions on August 28, 2018 and received public comments. DATES: This final rule is effective March 15, 2019.

SUPPLEMENTARY INFORMATION: Throughout this document whenever ‘‘we,’’ ‘‘us,’’ or ‘‘our’’ is used, we mean EPA. I. What is being addressed in this document? This rule addresses revisions to the Indiana SIP submitted by the Indiana Department of Environmental Management (IDEM) on February 28, 2017 and supplemented on January 9, 2018. EPA is approving a number of nonattainment plan elements included in that submission, specifically a revised 2011 base year emissions inventory for VOC and oxides of nitrogen (NOX), a 15% RFP plan, a 3% RFP contingency measure plan, 2017 VOC and NOX motor vehicle emissions budgets, a nonattainment NSR certification, a VOC RACT certification, and an enhanced I/M certification. The background for this action is discussed in detail in EPA’s proposal, dated August 28, 2018 (83 FR 43825). As discussed in the proposal, final approval of Indiana’s nonattainment NSR certification permanently stops the FIP clock triggered by EPA’s February 3, 2017 finding that Indiana failed to submit a marginal ozone nonattainment NSR plan. II. What comments did we receive on the proposed rule? EPA provided a 30-day review and comment period for the August 28, 2018, proposed rule. The comment period ended on September 27, 2018. We received a number of anonymous comments that address subjects outside the scope of our proposed action, do not explain (or provide a legal basis for) how the proposed action should differ in any way, and make no specific PO 00000 Frm 00043 Fmt 4700 Sfmt 4700 3711 mention of the substantive aspects of the proposed action. Consequently, these comments are not germane to this rulemaking and require no further response. In addition, one commenter submitted several comments that do not suggest a change in or specific problems with our proposed action. Therefore, these comments also require no further response. III. What action is EPA taking? Based on the above and the information contained in EPA’s proposed rule, EPA is approving revisions to Indiana’s SIP pursuant to section 110 and part D of the CAA and EPA’s regulations because Indiana’s February 28, 2017 nonattainment plan submission and January 1, 2018, supplement satisfy the emissions inventory, RFP, RFP contingency measures, transportation conformity, VOC RACT, I/M, and nonattainment moderate area NSR requirements of the CAA for the Indiana portion of the Chicago area for the 2008 ozone NAAQS. Final approval of Indiana’s SIP as meeting these nonattainment NSR requirements of the CAA for the 2008 ozone NAAQS permanently stops the and FIP clock triggered by EPA’s February 3, 2017 finding that Indiana failed to submit a marginal ozone nonattainment NSR plan. 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 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 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 E:\FR\FM\13FER1.SGM 13FER1

I. Background

    The background for this action is discussed in detail in our April 
25, 2018 proposal (83 FR 17964). In that document we proposed to 
approve the RFP demonstration, contingency measures, MVEBs and an 
updated 2011 base year emissions inventory for the HGB area.
    We received comments of support on the proposal from the Texas 
Commission on Environmental Quality and two relevant adverse comments 
from Environmental Integrity Project. Our response to the adverse 
comments are below.

II. Response to Comments

    Comment: Environmental Integrity Project commented that (1) it is 
unclear whether episodic emissions of ozone forming pollutants 
resulting from unplanned startups, shutdowns, maintenance, upsets and 
other unauthorized emissions are included in the Emissions Inventory 
ozone season daily nitrogen oxide (NOX) and volatile organic 
compound (VOC) values upon which the RFP plan is based and (2) to the 
extent that these values used to develop the baseline and future year 
emissions inventories do not include episodic emissions the RFP plan 
fails as a matter of law because the emissions inventories fail to 
include all actual emissions. The commenter notes that these emissions 
are quantifiable since companies report these episodic emissions to be 
included in TCEQ's emission inventory. The commenter also noted that 
researchers in the past have confirmed that these episodic emissions 
are important as they can sometimes result in large increases of ozone 
and are significant to the ozone problem in Houston and not including 
these episodic emissions in the RFP is erroneous. The commenter states 
that the RFP SIP must include a ``comprehensive, accurate, current 
inventory of actual emissions from all sources.''
    Response: CAA section 182(a)(1) requires states with ozone 
nonattainment areas to submit a SIP revision with a comprehensive, 
accurate, current inventory of actual emissions from all sources in an 
ozone nonattainment area in accordance with guidance provided by the 
Administrator. CAA section 182(b)(1) requires ozone nonattainment areas 
classified as Moderate and above to submit a RFP SIP revision. To 
implement CAA emissions inventory requirements for the 2008 ozone NAAQS 
we promulgated ``Emissions inventory requirements'' at 40 CFR 51.1115. 
The emissions values are required to be an average day's emissions for 
a typical ozone season work weekday (40 CFR 51.1115(c) and 40 CFR 
51.1100(cc)).
    To implement the RFP requirements for the 2008 ozone NAAQS we 
promulgated ``Requirements for reasonable further progress'' at 40 CFR 
51.1110. The values of the base year emissions inventory for RFP plans 
are to be an average day's emissions for a typical ozone season work 
weekday (40 CFR 51.1110(b) and 40 CFR 51.1100(cc)).
    Texas submitted a 2011 base year emissions inventory SIP revision 
for the HGB area on July 16, 2014 and we approved it as meeting the 
emissions inventory requirements for the 2008 ozone standard on 
February 20, 2015 (80 FR 9204). The RFP demonstration updated the 
previously approved emissions inventory with better estimates of an 
average day's emissions for a typical ozone season work weekday. A 
summary of the update to the 2011 base year emissions inventory is 
found in table 1.

    EPA's rules and guidance call for an estimate of typical ozone 
season day (summer weekday) emissions to set the RFP baseline. EPA's 
emission inventory guidance recommends including Startup, Shutdown, and 
Maintenance emissions in the RFP baseline and future year weekday ozone 
season day emission inventory values if the emissions can be reasonably 
and sufficiently quantified with regular and predictable emissions.\1\ 
Similarly, Texas emission inventory guidance is to include all 
authorized/planned \2\ Start-up, Shutdown and Maintenance emissions in 
the ozone season day emissions reported in annual emission inventories 
submitted by sources that are used by TCEQ for the RFP baseline and 
future year RFP inventories.\3\ In their RFP SIP, TCEQ included 
authorized/planned Start-up, Shutdown, and Maintenance (SSM) emissions 
from 2011 in their 2011 baseline inventory and also included 
authorized/planned emissions that occurred in 2014 in the 2014 
inventory that they used to project the 2017 future RFP inventory. 
Since the amount and magnitude of authorized/planned events varies from 
day to day, Texas includes the average value of these emissions in the 
RFP average weekday inventory.\4\ So, Texas does include an estimate of 
authorized/planned Start-up, Shutdown, and Maintenance emissions.

and Particulate Matter National Ambient Air Quality Standards 
(NAAQS) and Regional Haze Regulations''; EPA-454/B-17-003, July 
2017; pages 79-80. And ``Emissions Inventory Guidance for 
Implementation of Ozone and Particulate Matter National Ambient Air 
Quality Standards (NAAQS) and Regional Haze Regulations'', EPA-454/
B-17-003; July 2017, page 19, Section 2.5.2.
    \2\ The commenter discussed unplanned and unauthorized emissions 
and TCEQ guidance centers around authorized and non-authorized and 
does not use the unplanned/planned language. For this Response to 
Comment we are interpreting that the commenter was equating planned 
with authorized and unplanned with non-authorized.
    \3\ TCEQ RG-360A/11 ``2011 Emission Inventory Guidelines'' pages 
65-70 and TCEQ RG-360A/14, ``2014 Emission Inventory Guidelines'' 
pages 70-72.
    \4\ Texas receives data on the hours that the emissions occurred 
for each occurrence and then totals the emissions during ozone 
season and divides by the total number of hours that these types of 
emissions occurred to yield an average emission rate (lb/hr that is 
translated to OSD) that is included in the RFP inventories.
---------------------------------------------------------------------------

    Texas does not include unplanned startups, shutdowns, maintenance, 
upsets and other unauthorized emissions in their RFP inventories. This 
is consistent with EPA's guidance which states;\5\ ``Since malfunctions 
are, by nature, unpredictable and given the myriad different types of 
malfunctions that can occur, malfunction emissions would be difficult 
to estimate and future-year malfunction events cannot be readily 
predicted. Thus, states are not obligated to include malfunction 
emissions in the base inventory for the NAA, ROP/RFP plans, or 
attainment projected inventory for the NAA. However, to the extent that 
malfunctions become a regular and predictable event, then such 
emissions should be quantified with regular and predictable emissions 
and included in emission inventories for planning purposes. The 
elimination of high emissions during routinely reoccurring malfunctions 
could potentially help achieve significant emissions reductions needed 
by a state in attaining the relevant NAAQS.'' Malfunctions in EPA's 
terminology are very similar to unplanned events in TCEQ's regulatory 
structure. Because of the unpredictability and variability of unplanned 
and/or unauthorized emissions due to malfunctions, as explained in the 
EPA guidance it is reasonable that Texas did not include these 
emissions in its estimate of average ozone season weekday emissions.
---------------------------------------------------------------------------

and Particulate Matter National Ambient Air Quality Standards 
(NAAQS) and Regional Haze Regulations''; EPA-454/B-17-003, July 
2017; page 80.
---------------------------------------------------------------------------

    Although these unauthorized emissions are not appropriate to be 
included in the RFP plan, TCEQ recognizes the importance of emissions 
from startups, shutdowns, maintenance, and upsets/malfunctions. These 
episodic emissions (planned and unplanned) are quantified and included 
in the attainment demonstration modeling which better lends itself for 
utilization of day to day variation of emissions because daily 
emissions from specific historic episodes are modeled versus typical 
ozone season day weekday emissions used in the RFP inventories.\6\ 
Furthermore, based on the evolving knowledge about unplanned episodic 
emissions and the potential impacts on ozone levels, TCEQ has conducted 
a number of studies that have resulted in best management practice 
improvements for some point source categories to reduce episodic 
emission events.\7\ For example, TCEQ's studies have included best 
management practice improvements for flaring, which is one of the 
sources related with malfunctions and that may have the potential to 
impact ozone levels. These best management practice improvements are 
expected to result in emission reductions, but EPA acknowledges that 
quantification of baseline and future year emission events and non-
authorized/unplanned start-up, shutdown, and maintenance emissions 
(future year would be expected to be different than baseline) with the 
certainty required for a RFP SIP is not reasonably possible.

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

    In sum, Texas's approach is consistent with our emissions inventory 
guidance regarding non-authorized/unplanned episodic/malfunction 
emissions. EPA believes these emissions can vary significantly and 
unpredictably from day to day and therefore it is acceptable these 
emissions not be included in the periodic emissions inventory required 
under 40 CFR 51.1115(b) or the emissions inventory for RFP purposes. We 
note Texas recognizes the importance of these emissions and has 
undertaken efforts to reduce episodic emissions. In conclusion, TCEQ 
has met the requirements of 40 CFR 51.1110, 40 CFR 51.1115 and sections 
182(a)(1) and 182(b)(1) of the CAA.
    Comment: Environmental Integrity Project also stated that we may 
not rely on motor vehicle emissions reductions that we intend to 
discontinue. The comment stated that the single largest anticipated 
vehicle emissions reduction is from the Federal Motor Vehicle Control 
Program (FMVCP) and referred to an April announcement that we would 
work with the National Highway Traffic Safety Administration to revise 
the greenhouse gas (GHG) emissions standards and Corporate Average Fuel 
Economy (CAFE) standards for model year 2022 and 2025 light-duty 
vehicles.
    Response: EPA agrees that SIPs can only rely upon reductions that 
are enforceable for the purpose and years addressed by the SIP. 
However, it is incorrect that the RFP SIP relies on motor vehicle 
emissions reductions that we intend to discontinue. The RFP SIP 
addresses NOx and VOC emission levels for the year 2011 to 
2018, and during that time period the SIP relies on NOx and 
VOC emission reductions that have already occurred. In the case of the 
contingency measure reductions, these are expected to occur in 2018 due 
to regulations that have been implemented. In addition, it is important 
to note that the SIP relies upon EPA's emissions standard regulations 
which reduce criteria pollutant emissions. The GHG

[[Page 3710]]

regulations cited by the commenter do not affect criteria pollutant 
emissions standards and are also not related to the years addressed by 
the SIP.

III. Final Action

    We are approving the HGB RFP SIP revision submitted on December 29, 
2016, to meet the RFP requirements for the HGB moderate 2008 8-hour 
ozone nonattainment area as well as an updated 2011 base year emissions 
inventory for the 2008 Ozone NAAQS. This action is being taken under 
section 110 of the Act.

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 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 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, 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).
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit a report containing this action and 
other required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2).
    Under section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by April 15, 2019. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this action for the purposes of 
judicial review nor does it extend the time within which a petition for 
judicial review may be filed, and shall not postpone the effectiveness 
of such rule or action. This action may not be challenged later in 
proceedings to enforce its requirements. (See section 307(b)(2).)
