The Texas Commission on Environmental Quality (TCEQ) has issued revisions to Oil and Gas General Operating Permits (GOP) 511 and 514. The revisions were needed to to address the applicability status of Wise County. Sites in Wise County are now covered under GOP 511 instead of GOP 514. The revised GOPs were proposed on January 27, 2017, and the public comment period closed on February 27, 2017.

Current permit holders are required to submit an application for a new authorization to operate (ATO) no later than October 12, 2017, if any of the emission units, applicability determinations, or the basis for the applicability determinations are affected by the revisions in the renewed GOPs. If the revisions in the GOPs do not affect a site, a new ATO is not required.
