The Environmental Protection Agency (EPA) is conditionally approving revisions to the Texas New Source Review (NSR) State Implementation Plan (SIP) to establish the Texas Minor NSR Flexible Permits Program, submitted by the Texas Commission on Environmental Quality (TCEQ). The conditional approval is predicated on a commitment from TCEQ in a letter dated December 9, 2013, to adopt certain minor clarifications to the Flexible Permit Program by November 30, 2014. The EPA is finalizing this action under section 110 of the Clean Air Act (CAA).
