## I. Executive Summary

What actions are evaluated in this Technical Support Document?

This technical support document (TSD) reviews portions of four separate revisions to the General Air Quality Definitions of the Texas State Implementation Plan (SIP) , submitted on June 10, 2005; August 16, 2007; April 6, 2010; March 11, 2011; and May 26 , 2011 . This review will determine if the changes to the general air quality definitions applicable to the Texas SIP are consistent with the requirements of the Clean Air Act and EPA ’s policy and guidance.

June 10, 2005

 On May 25, 2005, the Texas Commission on Environmental Quality (TCEQ) adopted revisions to 30 TAC Chapter 101, Subchapter A, Section 101.1 to update the general air quality definitions to do the following: 1) substant ively revise the definition s of “maintenance area”, “maintenance plan” and “nonattaintment area” to address the one

- hour and eight

- hour ozone nonattainment designations to reflect the classifications under the existing one

- hour standard and to add the clas sifications under the new eight

- hour ozone standard , 2) substantively revise the definition of “VOC” by deleting the existing list of compounds and by referring to the federal definition in 40 CFR §51.100(s), except paragraphs (2)

- (4), as amended on Nove mber 29, 2004 (69 FR 69290

- 69304). The federal definition includes a special case for the compound t

- butyl acetate, which will not be considered a VOC for emission limitation or content purposes but will be considered a VOC for emissions reporting and inv ento ries and photochemical modeling and 3) multiple non

substantive changes to correct for readability, conformity with the drafting standards in the Texas Legislative Council Drafting Manual , November 2004, and consistency with other commission rules.

 The Chairman of the TCEQ, Ms. Kathleen Hartnett White

, submitted these provisions as a SIP revision in a letter dated June 10 2005, for rule project number 2005

- PR.

 EPA has acted on subsequent revisions to the definitions of “maintenance area”, “maint enance plan” and “nonattainment area” and “VOC”; effectively superceding the June 10, 2005 submittal of revised definitions. But we have yet to address the non

- substantive revisions submitted on June 10, 2005. August 16, 2007

 On July 25, 2007, the TCEQ ado pted revisions to 30 TAC Chapter 101, Subchapter A, Section 101.1 to update the general air quality definitions to do the following: 1) modify the opening paragraph to specify that the definitions apply to all Texas air quality rules, 2) revise the definit ions of “cold solvent cleaning,” “conveyorized degreasing,” and “open

- top vapor degreasing” by deleting the word “metal” so that the processes also apply to cleaning non

metal parts, 3) delete the definitions for “hazardous waste management facility” and

“ hazardous waste management unit” because references to these definitions were not found elsewhere in the air rules, 4) renumber the subsequent definitions because of the deletions, 5) revise the definition of “high

- volume low

- pressure spray guns” to specif y that the operating pressure of the equipment is measured at the air cap, 6) adopt the definition of “nitrogen oxides” from Chapter 117 because it is a common term throughout the Texas air quality rules, 7) modify the definition of “standard conditions”, and 8) modify the definition of “visible emissions”.

- 053

- 101

o Revisions to the Discrete Emission Credit Banking and Trading Program (referred to as the Discrete Emission Reduction Credit (DERC) Program) at 30 TAC Chapter 101, Subchapter H, Division 4 . EPA approved the re visions to the DERC Program on May 18, 2010 at 75 FR 27644.

o Revisions to the Sy stem Cap and Trade (SCT) Program at 30 TAC Chapter 101, Subchapter H, Division 5

. The TCEQ withdrew the SCT Program from our consideration as a SIP revision by letter on May 1, 2001. Further, on March 28, 2012, the TCEQ adopted the repeal of the SCT Program. Therefore, the SCT Program as revised on August 16, 2007 is no longer before us for review.

 EPA has acted on all portions of the August 16, 2007 submittal with the exceptio n of the revisions to the general defi ni tions at 30 TAC 101.1.

April 6, 2010

 On March 10, 2010, the TCEQ adopted revisions to 30 TAC 101.1 to update the general air quality definitions for “reportable quantity” and “volatile organic compound”.

 EPA approved the definition of “volatile organic compound” as corrected on December 28, 2011 at 76 FR 81371.

What is not included in this review?

This TSD will only review the revisions to the general air quality rules at 30 TAC 101.1 that have been submitted as a SIP revision. Where the TCEQ also adopted and submitted revisions to other parts of the Texas SIP, those revisions will be addressed in separa te rulemakings for the following reasons.

 Revisions to the HECT Program at 30 TAC Sections 101.390

– 101.394, 101.396, 101.399

– 101.401 adopted on March 10, 2010 and submitted as a revision to the Texas SIP on April 6, 2010. The HECT program revisions are severable from the general air quality definitions at 101.1 because they are not germane to the entirety of the Texas air quality control rules and program; rather, the HECT program addresses a specific subset of highly reactive VOCs in Harris County.

## II. Technical Evaluation of the SIP Submittals

The following table provides a line by line comparison of the SIP

- approved Definitions at 30 TAC 101.1 and each subsequent revision adopted and submitted as a revision to the Texas SIP. EPA’s analysis of the approvability of the revision is provided in italicized font immediately following any amendment that is more substantive than renumbering.

## III. Conclusion

The above analysis demonstrates that the following revisions to 30 TAC 101.1 are fully approvable:

 All non

- substantive revisions to 30 TAC 101.1 adopted on May 25, 2005 and submitted as a SIP revision on June 10, 2005 as part of Rule Project Number 2005

- 00 9

- 116

- PR. Note that EPA previously approved subsequent substantive revisions to “maintenance area”, “nonattainment area”, and “VOC”. Our later approval of subsequent revisions to these specific definitions supercede the 2005 submitted revisions.

 All revisi ons to 30 TAC 101.1 adopted on July 25, 2007 and submitted as a SIP revision on August 16, 2007 as part of Rule Project Number 2006

- 053

- 101

- PR.

 The revisions to “reportable quantity” and “volatile organic compound” adopted on March 10, 2010 and submitted a s a SIP revision on April 6, 2010, have been superceded by EPA’s approval of the revisions to the same definitions adopted on February 9, 2011 and submitted on March 11, 2011.

 The revisions to 30 TAC 101.1 “maintenance area”, “nonattainment area”, “reporta ble quantity”, and “volatile organic compound” adopted on February 9, 2011 and submitted on March 11, 2011, with corrections submit ted on May 26, 2011, have already been approved by EPA.

 However, our December 28, 2011, approval did not address the renumbe ring of the other definitions that had been adopted July 25, 2007 and carried forward into subsequent SIP submittals. Therefore, the renumbering through the March 11, 2011 SIP submittal is fully approvable.
