Docket No. EPA-R06-OAR-2011-0332 

1 

This is an addendum to the Technical Support Document (TSD) for the proposed action on SIP 

Revisions to the Texas SIP relating to Antibacksliding of Major NSR SIP Requirements for the OneHour Ozone National Ambient Air Quality Standards NAAQS; Major Nonattainment NSR (NNSR) SIP 

Requirements for the 1997 8-Hour Ozone NAAQS; and Major NSR Reform Program. This document 

identifies revisions to the TSD which is posted in the docket as document EPA-R06-OAR-2011-0332-

0008. These changes relate to a SIP submittal that the Texas Commission on Environmental Quality 

(TCEQ) submitted on August 29, 2012, that finalizes changes that TCEQ proposed on February 22, 

2012, and which EPA parallel processed in the June 20, 2012 proposal at 76 FR 36964. This revision 

also includes other changes that were made to the TSD (including the correction of typographical 

errors). 

The TSD posted in the docket as document EPA-R06-OAR-2011-0332-0008, is amended as described 

below 

1. Table 1 on pages 3 and 4 is revised as follows: 

a. The sixth column of the second row is revised to remove the references to 30 TAC 116.610 and 

116.617. These references were removed because this action does not address these rules. 

b. The sixth column of the fourth row is revised to remove the reference to 30 TAC 116.601. This 

reference was removed because this action does not address this rule. 

c. The second through sixth columns in the fifth row are revised to include the revisions that TCEQ 

adopted July 25, 2012. These revisions were proposed February 22, 2012, and parallel processed. 

d. The third through fifth columns of the sixth row are revised to conform to the revisions described 

in paragraph 1.c above 

e. Footnote (e

) following Table 1 is removed and footnote (f) is redesignated to footnote (e) to 

conform to the revisions described in paragraphs 1.c and d above. 

f. As revised, Table 1 reads as follows:

3. On page 15, footnote 10 is revise by replacing “51.166(w)(2)(ii)” with “51.166(w)(6)(ii).” This 

revision corrects a typographical error in the original TSD. 

4. On page 26, the last sentence in the first complete bullet on that page is revised by replacing 

“practically enforceable” with “practical enforceability.” This revision corrects a typographical 

error in the original TSD. 

5. On page 26, the last sentence in the second complete bullet on that page is revised by replacing 

“practically enforceable” with “practical enforceability.” This revision corrects a typographical 

error in the original TSD. 

6. General Comment. 

a. Throughout the TSD and the Appendix thereto, there are references to TCEQ’s revisions that 

were proposed February 22, 2012. TCEQ requested that EPA parallel process these proposed 

revisions in order to expedite the SIP approval process. In response to this request, EPA 

reviewed and proposed to approve the two revisions that were submitted March 11, 2011, and 

(through parallel processing) the revisions that TCEQ proposed on February 22, 2011. See 77 FR 

36964 (June 20, 2012). On July 25, 2012, the TCEQ adopted as final the revisions that it had 

proposed for on February 22. 2012. The final rules are that same as the proposed rule. The final 

rules became effective under State law on August 16, 2012. On August 29, 2012, TCEQ 

submitted these final rules to EPA for approval into the Texas SIP. 

The references in the TSD to the February 22, 2012, proposal were included prior to the final 

adoption of the proposed changes. We are not making revisions to the TSD to incorporate the 

dates of the final adoption and submittal of these changes because the changes are the same as 

the proposal and do not change the basis for the proposed and final approval. However, the 

information concerning the final adoption and submittal of the final rule are in the docket and are 

discussed in the final action.

b. EPA also received comments on the June 20, 2012, proposed rulemaking. These 

comments are posted in the docket and are discussed in the final action. Because the 

comments do not change the proposed action or the basis for the proposed action, we are 

not revising the TSD to address these comments.
