HGB Attainment Demonstration SIP Revision for the 2008 Eight-Hour Ozone NAAQS

On December 15, 2016, the commission adopted the HGB Attainment Demonstration (AD) State Implementation Plan (SIP) Revision for the 2008 Eight-Hour Ozone Standard Nonattainment Area (Project No. 2016-016-SIP-NR). The AD SIP revision meets Federal Clean Air Act (FCAA) requirements and includes a photochemical modeling analysis, a weight of evidence analysis, a reasonably available control technology analysis, a reasonably available control measures analysis, a motor vehicle emissions budget for 2017, and a contingency plan. The AD SIP revision incorporates revisions to 30 Texas Administrative Code Chapter 115.

HGB Reasonable Further Progress SIP Revision for the 2008 Eight-Hour Ozone NAAQS

On December 15, 2016, the commission adopted the HGB Reasonable Further Progress (RFP) SIP Revision for the 2008 Eight-Hour Ozone Standard Nonattainment Area (Project No. 2016-017-SIP-NR). To meet FCAA requirements, the SIP revision includes an analysis of reasonable further progress toward attainment of the 2008 eight-hour ozone standard, demonstrating a 15% emissions reduction in ozone precursors from the 2011 base year through the 2017 attainment year, a 3% emissions reduction for contingency in 2018, and updated RFP motor vehicle emissions budgets.

• Appendix 9: Aircraft Emissions Inventory for Texas Statewide 2014 AERR Inventory and 2008 through 2040 Trend Analysis Years
• Appendix 10: Development of On-Road Emission Inventories for the Years 2011, 2017, and 2018

Emissions Inventory (EI) SIP Revision for the 2008 Eight-Hour Ozone Standard for the HGB and Dallas-Fort Worth (DFW) Areas

On July 2, 2014, the commission adopted the EI SIP revision for the 2008 Eight-Hour Ozone Standard (Non-Rule Project No. 2013-016-SIP-NR). This SIP revision satisfies the FCAA, §172 and §182 requirements for the HGB and DFW nonattainment areas under the 2008 eight-hour ozone standard. The SIP revision includes 2011 emissions inventories for ozone precursors (volatile organic compounds and nitrogen oxides) from point, area, on-road mobile, non-road mobile, and biogenic emissions source categories as the base year emissions inventories for the HGB and DFW areas.
