### 66241 Federal Register / Vol. 81, No. 187 / Tuesday, September 27, 2016 / Proposed Rules

1 The area would be eligible for the second 1-year extension if the area’s 4th highest daily maximum 8-hour value, averaged over both the original attainment year and the first extension year, is at or below 0.075 ppm. 2 2014 and 2015 are the last two full years of complete air quality data prior to the July 20, 2016,
attainment date. **SUPPLEMENTARY INFORMATION :**  Throughout this document wherever ‘‘we,’’ ‘‘us,’’ or ‘‘our’’ is used, we mean the EPA.

I. Background

In 2008 we revised the 8-hour ozone primary and secondary NAAQS to a level of 0.075 parts per million (ppm) annual fourth-highest daily maximum 8- hour average concentration, averaged over three years to provide increased protection of public health and the environment (73 FR 16436, March 27, 2008). The HGB area was classified as a ‘‘Marginal’’ ozone nonattainment area for the 2008 8-hour ozone NAAQS and initially given an attainment date of no later than December 31, 2015 (77 FR 30088, May 21, 2012). The HGB area consists of Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery and Waller counties.

On December 23, 2014, the D.C. Circuit 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 ozone nonattainment areas, including the HGB area as July 20, 2015 (80 FR 12264, March 6, 2015). As the HGB area qualified for a 1-year extension of the
attainment deadline we revised the attainment deadline to July 20, 2016 (81 FR 26697, May 4, 2016).

Classifications for ozone nonattainment areas range from ‘‘Marginal’’ (for areas with monitored ozone levels just exceeding the level of the NAAQS) to ‘‘Extreme’’ (for areas
with monitored ozone levels well above the levels of the NAAQS). CAA section 182 stipulates the specific attainment planning and additional requirements that apply to each ozone nonattainment
area based on its classification. CAA section 182, as interpreted by the EPA’s implementation regulations at 40 CFR 51.1108–1117, also establishes the timeframes by which air agencies must
submit SIP revisions to address the applicable attainment planning elements, and the timeframes by which
ozone nonattainment areas must attain the relevant NAAQS.

CAA section 181(b)(2) requires us to (1) determine whether the HGB area attained the 2008 ozone NAAQS by the attainment deadline, (2) reclassify the
HGB area if the attainment deadline is not met, and (3) publish a Federal Register notice within 6 months of the attainment deadline identifying the new
classification if the area failed to attain by the attainment deadline. The
determination of attainment is based on the area’s ‘‘design value’’ (DV), which for the 8-hour ozone NAAQS is the highest 3-year average of the annual fourth highest daily maximum 8-hour average ozone concentration of all regulatory monitors in the area. The 2008 ozone NAAQS is met when the DV is less than or equal to 0.075 ppm based on complete, consecutive calendar years of certified, quality assured ambient air monitoring data (40 CFR 50.15; 40 CFR 50, appendix P). A determination of attainment by the attainment deadline of July 20, 2016 is based on data from the consecutive calendar years of 2013–

2015.

II. EPA Analysis

Ozone air quality data from monitoring sites in the HGB area is presented in Table 1. This data has been quality assured and certified by the
State of Texas. The data is available in the EPA Air Quality System (AQS)
database and also in the electronic
docket for this action. The Manvel monitoring site (48–039–1004) recorded the highest 2013–2015 design value (0.080 ppm), which is also the DV for the area. Although the HGB air trends show overall progress in reducing ozone concentrations over the past 15 years, the HGB area is not eligible for an additional one-year attainment date
extension 1 because, at 0.078 ppm, the average of the 2014 and 2015 2 annualfourth highest daily maximum eighthour average ozone concentrations for the monitor in the area is greater than 0.075 ppm, the data for 2014–2015 indicates the area does not qualify for a second 1-year extension of the attainment deadline (40 CFR 51.1107).

3 See 40 CFR 51.112(a)(3)

.

4 See 81 FR 26697, May 4, 2016

. CAA section 181(b)(2)(A) provides that a marginal nonattainment area shall be reclassified by operation of law upon a determination by the EPA that such area failed to attain the relevant NAAQS by the applicable attainment date. Based on quality-assured ozone monitoring data from 2013–2015, as shown in Table 1, the new classification applicable to the HGB area would be the next higher classification of ‘‘moderate’’ under the CAA statutory scheme. Moderate nonattainment areas are required to attain the standard ‘‘as expeditiously as practicable’’ but no later than six years after the initial designation as nonattainment (which, in the case of the HGB area, is July 20, 2018). The attainment deadlines associated with each classification are prescribed by the CAA and codified at 40 CFR 51.1103.

In determining the deadline for the Moderate area SIP revisions, the EPA has discretion, per CAA section 182(i), to adjust the statutory deadline for submitting required SIP revisions for reclassified Moderate ozone nonattainment areas. CAA section 182(i) requires that reclassified areas meet the applicable plan submission requirements ‘‘according to the schedules prescribed in connection with such requirements, except that the Administrator may adjust any applicable deadlines (other than attainment dates) to the extent such adjustment is necessary or appropriate to assure consistency among the required submissions.’’ Under the Moderate area plan requirements of CAA section 182(b)(1) and 40 CFR 51.1108, states with ozone nonattainment areas classified as Moderate are provided 3 years (or 36 months) from the date of designation to submit a SIP revision complying with the Moderate ozone nonattainment plan requirements. For areas designated nonattainment for the 2008 ozone NAAQS and originally classified as Moderate, that deadline was July 20, 2015, a date that has already passed.

The EPA, therefore, interprets CAA section 182(i) as providing the authority to adjust the applicable deadlines for the HGB area ‘‘as necessary or appropriate to assure consistency among the required submissions.’’ In determining a SIP submission deadline, we note that pursuant to 40 CFR 51.1108(d), for each nonattainment area the state must provide for implementation of all control measures needed for attainment no later than the beginning of the attainment year ozone season. The attainment year ozone season is the ozone season immediately preceding a nonattainment area’s attainment date, in this case it is the 2017 ozone season (40 CFR 51.1100(h)). The ozone season is the ozone monitoring season as defined in 40 CFR part 58, appendix D, section 4.1, table D–3. For the purpose of this HGB area reclassification, January 1st is the beginning of the ozone monitoring season. Therefore, the beginning of the Moderate attainment year ozone season for the HGB area is January 1, 2017. This date is also the latest date that would be compatible with the deadline for Moderate area reasonably available control technology (RACT) to be in place (i.e., begin no later than January 1 of the 5th year after the effective date of designation for the 2008 ozone NAAQS, which is, in this case, January 1, 2017). 3 Also, January 1, 2017 is the SIP submission deadline the EPA established for all other Marginal nonattainment areas in the country that were recently reclassified to Moderate. 4

Accordingly, the EPA proposes that the required SIP revisions be submitted by Texas no later than January 1, 2017. This deadline also calls for implementation of applicable controls no later than January 1, 2017. Texas must submit a Moderate Area SIP that addresses the CAA’s Moderate nonattainment area requirements as described in 40 CFR 51.1100. Those requirements include, (1) An attainment demonstration (CAA section 182(b) and 40 CFR 51.1108); (2) reasonable further progress (RFP) reductions in volatile organic compound (VOC) and nitrogen oxide (NO X) emissions (CAA sections 172 (c)(2) and 182(b)(1) and 40 CFR 51.1110); (3) provisions for reasonably available control technology (RACT) (CAA section 182(b)(2) and 40 CFR 51.1112(a)–(b)) and reasonably available control measures (RACM) (CAA section 172(c)(1) and 40 CFR 51.1112(c)); and (4) contingency measures to be implemented in the event of failure to meet a milestone or attain the standard (CAA 172(c)(9)); (5) a vehicle inspection and maintenance program (CAA section 181(b)(4) and 40 CFR 51.350); and (6)
NO X and VOC emission offsets at a ratio of 1.15 to 1 for major source permits (CAA section 182(b)(5) and 40 CFR 51.165 (a)) See also the requirements for
moderate ozone nonattainment areas set forth in CAA section 182(b) and the general nonattainment plan provisions required under CAA section 172(c).

Should the State’s analysis find that
the area will not meet the Moderate area attainment deadline of July 20, 2018, the State can seek a voluntary reclassification to a higher classification category, which would provide additional time for attainment. We believe that voluntary reclassification for areas that are not likely to attain by their attainment date is an appropriate
action that will facilitate focus on developing the attainment plans required (80 FR 12264, 12268, March 6, 2015). A voluntary reclassification to
the Serious classification would set an attainment deadline of July 20, 2021 (40 CFR 51.1103).

III. Proposed Action

In accordance with CAA 181(b)(2), we are proposing to determine that the HGB
ozone nonattainment area failed to attain the 2008 ozone NAAQS by the applicable attainment deadline of July 20, 2016, and to reclassify the area as Moderate. We are also proposing that
Texas must submit to us the SIP
revisions to address the Moderate ozone nonattainment area requirements of the CAA by January 1, 2017.

The EPA acknowledges that for the HGB area reclassified from Marginal to Moderate nonattainment, meeting the SIP submittal deadline of January 1, 2017 may be challenging. The EPA is working closely with TCEQ to support their SIP submittal in a timely manner. As discussed previously in section II of this notice, January 1, 2017 is a SIP
submission deadline that is consistent for all Marginal nonattainment areas
that are reclassified to Moderate for the 2008 ozone NAAQS, and is consistent
with the timeframes in the CAA as codified in the EPA’s implementing regulations.

IV. Statutory and Executive Order
Reviews

A. Executive Order 12866: Regulatory Planning and Review and Executive Order 13563: Improving Regulation and Regulatory Review

This action is not a significant regulatory action and was therefore not submitted to the Office of Management and Budget for review.

B. Paperwork Reduction Act (PRA)

This proposed action does not impose
an information collection burden under the PRA because it does not contain any
information collection activities.

C. Regulatory Flexibility Act (RFA)

I certify that this action will not have a significant economic impact on a
substantial number of small entities under the RFA. This action merely proposes to determine that the HGB area failed to meet an ozone NAAQS attainment deadline, reclassify the area
and set the date when a revised SIP is
due to EPA.

D. Unfunded Mandates Reform Act (UMRA)

This action does not contain any
unfunded mandate as described in UMRA, 2 U.S.C. 1531–1538, and does not significantly or uniquely affect small governments. The action imposes no enforceable duty on any state, local or tribal governments or the private sector.

E. Executive Order 13132: Federalism

This action does not have federalism implications. It will not have substantial direct effects on the states, on the relationship between the national government and the states, or on the distribution of power and responsibilities among the various levels of government.

F. Executive Order 13175: Consultation
and Coordination With Indian Tribal

Governments

This action does not have tribal implications as specified in Executive Order 13175. This action does not apply on any Indian reservation land, any
other area where EPA or an Indian tribe
has demonstrated that a tribe has jurisdiction, or non-reservation areas of Indian country. Thus, Executive Order 13175 does not apply to this action.

G. Executive Order 13045: Protection of
Children From Environmental Health Risks and Safety Risks

EPA interprets Executive Order 13045 as applying only to those regulatory
actions that concern environmental health or safety risks that the EPA has reason to believe may disproportionately affect children, per the definition of ‘‘covered regulatory
action’’ in section 2–202 of the
Executive Order. This action is not subject to Executive Order 13045 because it merely proposes to determine
that the HGB area failed to meet an ozone NAAQS attainment deadline, reclassify the area and set the date when
a revised SIP is due to EPA.

H. Executive Order 13211, Actions That Significantly Affect Energy Supply,
Distribution or Use

This action is not subject to Executive Order 13211, because it is not a significant regulatory action under
Executive Order 12866.

I. National Technology Transfer and
Advancement Act

This rulemaking does not involve
technical standards. J. Executive Order 12898: Federal
Actions To Address Environmental Justice in Minority Populations and Low-Income Populations

EPA believes the human health or environmental risk addressed by this action will not have potential disproportionately high and adverse
human health or environmental effects on minority, low-income or indigenous populations. This action merely proposes to determine that the HGB area failed to meet an ozone NAAQS attainment deadline, reclassify the area
and set the date when a revised SIP is
due to EPA.
