I. Background

On July 28, 2016, Texas Commission on Environmental Quality (TCEQ) submitted a SIP revision to EPA for review and approval. The SIP revisions include amendments to 30 TAC Section 101.1 and 101.10 in 30 TAC Chapter 101, General Air Quality Rules, Subchapter A, General Rules and corresponding revisions to the State Implementation Plan (SIP). The submitted revisions are described below:

1. Definitions Updates—TAC Chapter 101, Section 101.1

EPA periodically revises the list of negligibly reactive compounds to add or delete organic volatile compounds (VOC) from regulation on the basis that these compounds make a negligible contribution to tropospheric ozone [1] formation. Section 302(s) of the CAA specifies that the EPA has the authority to define the meaning of “VOC,” and hence what compounds shall be treated as VOCs for regulatory purposes. The policy of excluding negligibly reactive compounds from the VOC definition was first set forth in the “Recommended Policy on Control of Volatile Organic Compounds” (42 FR 35314, July 8, 1977) and was supplemented most recently with the “Interim Guidance on Control of Volatile Organic Compounds in Ozone State Implementation Plans” (Interim Guidance) (70 FR 54046, September 13, 2005). The EPA uses the reactivity of ethane as the threshold for determining whether a compound has negligible reactivity. Compounds that are less reactive than, or equally reactive to, ethane under certain assumed conditions may be deemed negligibly reactive and therefore suitable for exemption from the regulatory definition of VOC. Compounds that are more reactive than ethane continue to be considered VOCs for regulatory purposes and therefore are subject to control requirements. The selection of ethane as the threshold compound was based on a series of smog chamber experiments that underlay the 1977 policy.

The EPA lists compounds that it has determined to be negligibly reactive in its regulations as being excluded from the definition of VOC. (40 CFR 51.100(s)). The specific organic compounds that will be excluded from TCEQ's definition of VOC that is in the SIP with this revision include: trans-1,3,3,3-tetrafluoropropene; 2,3,3,3-tertrafluropropene,[2] HCF2 OCF2 H (HFE-134); HCF2 OCF2 OCF2 H (HFE-236cal2); HCF2 OCF2 CF2 OCF2 H (HFE-338pcc13); HCF2 OCF2 OCF2 CF2 OCF2 OCF2 H (H-Galden 1040x or H-Galden ZT 130(or150 or 180)),[3] trans- 1-chloro-3,3,3-trifluoroprop-1-ene,[4] and 2-amino-2-methyl-1-propanol,[5] Texas is updating its SIP to be consistent with current EPA definitions to provide clarity and consistency for owners and operators of sources subject to TCEQ rules regarding VOC control.

2. Emission Inventory Requirements in TAC Chapter 101, Section 101.10

A. Lead Reporting Threshold

On February 6, 2015 (80 FR 8787), the EPA finalized revisions to 40 Code of Federal Regulations (CFR) Part 51, Subpart A, Air Emissions Reporting Rule (AERR) and in 40 CFR 51.122 that lowered the lead (Pb) point source reporting threshold to 0.5 tons per year (tpy). The purpose of this change was to match requirements of the Pb Ambient Air Monitoring Requirements rule (75 FR 81126), which required monitoring agencies to install and operate source-oriented ambient monitors near Pb sources emitting 0.50 tpy or more by December 27, 2011. With this action, the EPA lowered the point source threshold for Pb emissions to 0.5 tons per year (tpy) of actual emissions. The current TCEQ emissions inventory (EI) reporting rule at 30 TAC Section 101.10 in the SIP (and previous version of the AERR) language requires a source to submit an EI if it has 10 tpy or more of actual or 25 tpy or more of potential lead emissions. Currently, the data needed to meet the new EPA lead reporting threshold requirement are collected under TCEQ's special inventory [6] which requires TCEQ to annually identify and contact these sources for an inventory. This revision for lowering the lead reporting threshold aligns 30 TAC Section 101.10 with the reporting requirements in the EPA's AERR (40 CFR part 51) and would require sources to self-identify and report a full and complete EI annually if they emit 0.5 tpy or more of lead.

B. Off-Shore Emission Inventory Reporting Requirement

Under the current SIP, sources within 25 statute [7] miles from the shoreline are required to submit an EI if the source meets one of the reporting threshold in 30 TAC Section 101.10. TCEQ proposed amendment shortens the applicable distance for a site on waters from 25 statute miles to 9.0 nautical [8] miles (10.4 statute miles) from the shoreline.[9] Texas' territorial waters only extend 9.0 nautical miles. At this time, no sites located between 9.0 nautical miles and 25 statute miles from the shoreline are reporting EIs to Texas. If a site existing between 9.0 nautical miles and 25 statute miles from shore should be required to report in the future, this site would be captured in a federal EI. This revision to align Texas rules with the current federal regulations found in 40 CFR part 51 will clarify requirements in 30 TAC Section 101.10 and change applicability to sources that are within 9.0 nautical miles of the shoreline in accordance with state and federal jurisdiction over offshore sources.

C. Definition and Terminology Revisions

a. 30 TAC Section 101.10(a) requires an inventory to be submitted on forms or other media. The commission adopted amendment removes the redundant phrase “forms or other” from this subsection. The phrase “media” succinctly covers this requirement.

b. Currently, the data needed to meet the new EPA lead reporting threshold requirement as discussed previously are collected under the special inventory requirement in the SIP's subsection (b)(2) and (3). The amendment in TCEQ's revision makes the requirement clear to the community and does not require the agency to rely on the special inventory provision to collect data that is reported annually.

c. All owners or operators of accounts continuing to meet the SIP's reporting requirements in subsection (a) are required to annually update their EI. The amendment adds subsection (a)(5) to the list of applicability requirements listed in subsection (b)(2) that are required to submit an annual emissions inventory update (AEIU). This addition includes the adopted inclusion of the new lead reporting requirement to this existing requirement.

d. An amendment in subsection (a)(5) to change the units from “tons” to “tpy” to more clearly define the period over which the emissions are calculated. An annual time-period has always been assumed for this applicability by the State and EPA but the amendment is to clarify.

e. The term “microns” is changed to “micrometers' in the adoption to align language in 30 TAC Section 101.10(b)(1) with the reporting rule in AERR. In applied sciences, a micron is commonly accepted alternative term to micrometer, and thus, the adopted amendment has no effect on the population of sources required to report an EI or on the methodology for estimating emissions.

f. Particulate matter with aerodynamic diameter less than or equal to 2.5 micrometers (PM2.5) is added to the list of contaminants that shall be reported in the EI under subsection (b). The list includes the phrase “any other contaminants”, PM2.5 is subject to the NAAQS and is already required for inclusion in an EI. However, specifically listing PM2.5 clarifies the reporting requirement and does not change any existing reporting requirement to the agency.

g. A second certifying statement has been added as 30 TAC Section 101.10(d)(2). Texas Health and Safety Code (THSC), Section 382.0215(f) requires that an owner or operator that is required to submit an EI and had no emissions events during the reporting year must include as part of the inventory a statement to this effect. The EI update process and reporting forms already include this certifying statement. An EI cannot be considered completed or for electronically submitted accounts, submitted without either completing this certification or submitting emissions event data. The amendments do not change this practice nor the wording in the certifying statement on the EI; it only includes the existing practice, which is required by THSC Section 382.0215 and reflected in 30 TAC Section 101.10.

II. The EPA's Evaluation

On July 28, 2016, TCEQ submitted SIP revisions to EPA for review and approval. The revisions amend Emission Inventory and General Air Quality rules in 30 TAC Chapter 101. The amended rules will incorporate EPA's latest finalized definitions of VOC compounds, align the lead reporting threshold with the AERR, shorten the distance from the shoreline for applicable offshore sources to report an emission inventory, and revise terminology and definitions for clarity and consistency with the EPA's AERR. These changes are consistent with section 110 of the CAA and meet the regulatory requirements pertaining to the SIPs.

III. Final Action

Pursuant to section 110 of the CAA, EPA is approving the SIP revisions TCEQ submitted to EPA regarding the above revisions to 30 TAC Chapter 101 Emissions Inventory and General Definitions update. These revisions are consistent with section 110 of the CAA and meet the regulatory requirements pertaining to SIPs.Start Printed Page 26598

EPA is publishing this rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipate no adverse comments. However, in the proposed rules section of this Federal Register publication, EPA is publishing a separate document that will serve as the proposal to approve the SIP revision should relevant adverse comments be filed. This rule will be effective September 6, 2017 without further notice unless the Agency receives relevant adverse comments by July 10, 2017. If EPA receives relevant adverse comments, EPA will publish a timely withdrawal of the rule in the Federal Register and inform the public that the rule will not take effect.

IV. Incorporation by Reference

In this action, we are proposing to include in a final rule regulatory text that includes incorporation by reference. In accordance with the requirements of 1 CFR 51.5, we are proposing to incorporate by reference revisions to the Texas regulations as described in the Final Action section above. We have made, and will continue to make, these documents generally available electronically through www.regulations.gov and/or in hard copy at the EPA Region 6 office.

V. 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).

Samuel Coleman was designated the Acting Regional Administrator on May 24, 2017 through the order of succession outlined in Regional Order R6-1110.13, a copy of which is included in the docket for this action.

Footnotes

1.  Tropospheric ozone, commonly known as smog, is formed when VOCs and nitrogen oxides (NOX) react in the atmosphere in the presence of sunlight. Because of the harmful health effects of ozone, the EPA and state governments limit the amount of VOCs that can be released into the atmosphere. VOCs are those organic compounds of carbon that form ozone through atmospheric photochemical reactions. Different VOCs have different levels of reactivity. That is, they do not react to form ozone at the same speed or do not form ozone to the same extent. Some VOCs react slowly or form less ozone; therefore, changes in their emissions have less and, in some cases, very limited effects on local or regional ozone pollution episodes. It has been the EPA's policy that organic compounds with a negligible level of reactivity should be excluded from the regulatory VOC definition so as to focus VOC control efforts on compounds that do significantly increase ozone concentrations. The EPA also believes that exempting such compounds creates an incentive for industry to use negligibly reactive compounds in place of more highly reactive compounds that are regulated as VOCs.
