SIP Revisions: Houston-Galveston-Brazoria, May 23, 2007

Revisions to the Texas state implementation plan (SIP) developed for the Houston-Galveston-Brazoria (HGB) 1997 eight-hour ozone National Ambient Air Quality Standard (NAAQS) moderate nonattainment area.

Background

Effective June 15, 2004, Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, and Waller Counties were designated nonattainment in Phase I of the United States Environmental Protection Agency’s (EPA) implementation rule for the 1997 eight-hour ozone NAAQS (69 FR 23951, April 30, 2004) Exit the TCEQ. The HGB area was classified moderate nonattainment for the standard, with an attainment deadline of June 15, 2010. The TCEQ was required to submit a SIP revision for the 1997 eight-hour ozone NAAQS to the EPA by June 15, 2007. The EPA addressed the control obligations that apply to areas designated nonattainment for the 1997 eight-hour ozone NAAQS in the Phase II implementation rule (70 FR 71612, November 29, 2005) Exit the TCEQ.

On May 23, 2007, the commission adopted the 2007 HGB 1997 Eight-Hour Ozone Nonattainment Area SIP Revision and the 2007 HGB 1997 Eight-Hour Ozone Nonattainment Area RFP SIP Revision. The commission also adopted associated rule projects revising 30 Texas Administrative Code (TAC) Chapters 114 and 115 and repealing one of the nitrogen oxides (NOx) standards in the residential water heater rules in 30 TAC Chapter 117. On June 15, 2007, the TCEQ submitted the 2007 HGB 1997 Eight-Hour Ozone Nonattainment Area SIP Revision and the 2007 HGB 1997 Eight-Hour Ozone Nonattainment Area RFP SIP Revision to the EPA along with a request that the HGB area be reclassified from a moderate to a severe nonattainment area for the 1997 eight-hour ozone NAAQS, with an attainment deadline of June 15, 2019. (See the governor’s 2007 reclassification request letter.)

2007 HGB 1997 Eight-Hour Ozone Nonattainment Area SIP Revision

Adoption Date: May 23, 2007

Proposal Date: December 13, 2006

EPA Approval Date: RACT analysis and VMEP (78 FR 19599, April 2, 2013) Exit the TCEQ; RFP Plan, Motor Vehicle Emissions Budgets, and Revised 2002 Base Year Emissions Inventory (74 FR 18298, April 22, 2009) Exit the TCEQ

SIP Revision Summary: The 2007 HGB 1997 Eight-Hour Ozone Nonattainment Area SIP Revision was the first step in addressing the 1997 eight-hour ozone standard in the HGB area. This SIP revision included additional Voluntary Mobile Emissions Reduction Program (VMEP) commitments, a Reasonably Available Control Technology (RACT) analysis, and the Texas 2002 Periodic Emissions Inventory for the HGB 1997 eight-hour ozone nonattainment area. This 2007 HGB 1997 Eight-Hour Ozone Nonattainment Area SIP Revision incorporated amendments to 30 TAC Chapter 114 to add certain marine fuels to the Texas Low Emission Diesel (TxLED) rules and Chapter 115 to address under-estimated, unreported, or under-reported volatile organic compounds (VOC) emissions from storage tank floating roof landings, flash emissions, and from degassing storage tanks, transport vessels, and marine vessels with liquid heels. In an associated rulemaking project, 30 TAC Chapter 117 was reformatted and the 10 nanogram per Joule heat input (ng/J) NOx standard for residential water heaters was repealed in accordance with House Bill 965, 79th Legislature, 2005. The emission standard of 40 ng/J NOx was retained.

Adopted SIP Narrative and Appendices

Note: Revisions proposed to photochemical modeling and corroborative analysis in Chapters 2 and 3, the RACM analysis in Chapter 4 and Appendix C, and the contingency measures in Chapter 4 were removed before adoption to allow time for them to be more adequately addressed. (See the SIP Revisions: Houston-Galveston-Brazoria, March 10, 2010, December 7, 2011, and April 23, 2013 Web page.) The adopted appendices were re-lettered accordingly.
