TX044.50 Approval and Promulgation of Implementation Plans - Texas - Excess Emissions During Startup, Shutdown, Maintenance (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the TX044.50 Approval and Promulgation of Implementation Plans - Texas - Excess Emissions During Startup, Shutdown, Maintenance (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 The EPA is finalizing its proposal to partially approve and partially disapprove a revision to the Texas State Implementation Plan (SIP) submitted by the Texas Commission on Environmental Quality (TCEQ) in a letter dated January 23, 2006 (the January 23, 2006 SIP submittal). Today's action finalizes our May 13, 2010 proposal that concerned revisions to 30 Texas Administrative Code (TAC) Chapter 101, General Air Quality Rules, Subchapter A General Rules; and Subchapter F Emissions Events and Scheduled Maintenance, Startup, and Shutdown Activities. We are finalizing our proposed approval of those portions of the rule that are consistent with the federal Clean Air Act (the Act or CAA), and finalizing our proposed disapproval of those portions of the rule that are inconsistent with the Act. More specifically, we are finalizing our proposed disapproval of provisions that provide for an affirmative defense against civil penalties for excess emissions during planned maintenance, startup, or shutdown activities and related provisions that contain nonseverable cross-references to the affirmative defense provision. A disapproval of these provisions means that an affirmative defense is not available in an enforcement action in Federal court to enforce the SIP for violations due to excess emissions during planned maintenance, startup, or shutdown activities. We are taking this action under section 110 of the Act.

We are approving the nonsubstantive renumbering of the rules for all five counties. We also are approving the substantive changes to the rules for Ellis County, based on a determination that the rules for Ellis County meet the NO X Reasonably Available Control Technology (RACT) requirements for cement kilns operating in the Dallas Fort Worth (D/FW) 1997 8-hour ozone nonattainment area.

TX082.28 Approval and Disapproval and Promulgation of Implementation Plans - Texas - Infrastructure and Interstate Transport Requirements for the 1997 (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the TX082.28 Approval and Disapproval and Promulgation of Implementation Plans - Texas - Infrastructure and Interstate Transport Requirements for the 1997 (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 The EPA is partially approving and partially disapproving submittals from the state of Texas pursuant to the Clean Air Act (CAA or Act) that address the infrastructure elements specified in the CAA section 110(a)(2), necessary to implement, maintain, and enforce the 1997 8-hour ozone and 1997 and 2006 fine particulate matter (PM 2.5) national ambient air quality standards (NAAQS or standards). We are determining that the current Texas State Implementation Plan (SIP) meets the infrastructure requirements for the 1997 8-hour ozone and the 1997 and 2006 PM 2.5 NAAQS at 110(a)(2)(A), (B), (E), (F), (G), (H), (K), (L), (M), and portions of (C), (D)(ii) and (J). We are determining that the current Texas SIP does not meet the infrastructure requirements for the 1997 8-hour ozone and the 1997 and 2006 PM 2.5 NAAQS at 110(a)(2) for portions of (C), (D)(ii) and (J). The EPA is also partially approving and partially disapproving SIP revisions submitted by the state of Texas for the purpose of addressing the provisions of CAA section 110(a)(2)(D)(i) for the 1997 8-hour ozone NAAQS and the 1997 and 2006 PM 2.5 NAAQS. These SIP revisions address the requirement that the Texas SIP have adequate provisions to prohibit air emissions from adversely affecting another state's air quality through interstate transport. The EPA is partially approving and partially disapproving the provisions of these SIP submissions that emissions from sources in Texas do not interfere with measures required in the SIP of any other state under part C of the CAA to prevent significant deterioration of air quality, with regard to the 1997 8-hour ozone NAAQS and the 1997 and 2006 PM 2.5 NAAQS. The partial disapprovals herein are because Texas has stated it cannot issue permits for and does not intend to regulate greenhouse gas (GHG) emissions. The EPA is also approving SIP revisions that modify the Texas SIP for Prevention of Significant Deterioration (PSD) to include nitrogen oxides (NO X) as an ozone precursor. This action is being taken under section 110 and part C of the Act.
