EPA provided a 30

- day comment period on our proposed rulemaking, ending on January 23, 2014. We received two comment letters, generally supportive of our proposed rulemaking. Our final approval notice provides responses to the comment s from the Texas Pipeline Association. The comments received from the Texas Commission on Environmental Quality (TCEQ) prompted us to review our proposed approval and clarify statements made in our analysis.

The TCEQ provided further information about the public notice process used for the Standard Permit for Oil and Gas Facilities at 30 TAC Section 116.620. The TCEQ noted that “the commission adopts standard permits in an open meeting, for which notice is posted at least seven days in advance and which pro vides an additional opportunity for public comment on the standard permit.”

In our proposed rulemaking, EPA proposed to find that the SIP

- approved public participation requirements at 30 TAC Section 116.603 are applicable to the Oil and Gas Standard Permit at 30 TAC Section 116.620 . This statement was in error. 30 TAC Section 116.603 is the public notice process used for the development of a non

- rule Standard Permit (such as the Non

- Rule Oil and Gas Standard Permit for the Barnett Shale) and is similar to, but separate from the public notice process used in the development of the Standard Permits that are adopted by rule (such as the Oil and Gas Standard Permit at 30 TAC 116.620)

. For the Oil and Gas Standard permit at 30 TAC Section 116.620, the Standard permit was developed and public noticed using the statutory requirements at Texas Government Code

, Chapter 2001, Subchapter B

, as authorized by the Texas Clean Air Act, Chapter 382 of the Texas Health and Safety Code. These provisions require public notice of the proposed Standard Permit in the Texas Register ; a 30

- day comment period on the proposed Standard Permit ; and that the TCEQ adopts rule standard permits in a public meeting, which provides an additional opportunity for public comment. Our analysis of the SIP submittals in the proposal and TSD demonstrated that the TCEQ followed all necessary procedural requirements for the development of a SIP revision as specified in 40 CFR 51.102 and 51.104, including public notice requirements such as providing a 30

- day comment period and holding a public hearing . This process is consistent with the Minor NSR requirements for public notice at 40 CFR 51.161. We find that the public participa tion process that TCEQ used for the Oil and Gas Standard Permit as currently submitted meets the Minor NSR requirements at 40 CFR 51.161.
