Environmental Protection Agency 40 CFR Parts 52 and 97 [EPA-R06-OAR-2016-0611; FRL-10001-85-Region 6] AGENCY: Environmental Protection Agency (EPA). ACTION: Supplemental notice of proposed rulemaking. SUMMARY: In this supplemental notice of proposed rulemaking (SNPRM), the Environmental Protection Agency (EPA) is supplementing the proposal published on August 27, 2018 to affirm the Agency's October 2017 Federal Implementation Plan (FIP), which partially approved the 2009 Texas Regional Haze State Implementation Plan (SIP) submission and promulgated a Federal Implementation Plan (FIP) for Texas to address certain outstanding Clean Air Act (CAA) regional haze requirements. The October 2017 FIP established the Texas SO 2 Trading Program, an intrastate trading program for certain electric generating units (EGUs) in Texas, as a Best Available Retrofit Technology (BART) alternative for sulfur dioxide (SO 2 ). In response to certain comments received on the August 2018 proposal to affirm the October 2017 FIP, we are proposing revisions to the Texas SO 2 Trading Program, including provisions for penalties on the total annual SO 2 emissions from sources covered by the rule exceeding a proposed assurance level. DATES: Comments must be received on or before January 13, 2020.
