The Environmental Protection Agency (EPA) Region 6 Regional Administrator is considering an alternative interpretation regarding affirmative defense provisions in State Implementation Plans (SIPs) of states in EPA Region 6 that departs from the EPA's 2015 policy on this subject. In accordance with the Federal Clean Air Act (Act or CAA), the EPA Region 6 is proposing to make a finding that the affirmative defense provisions in the SIP for the state of Texas applicable to excess emissions that occur during certain upset events and unplanned maintenance, startup, or shutdown activities are narrowly tailored and limited to ensure protection of the National Ambient Air Quality Standards (NAAQS) and other CAA requirements, and would be consistent with the newly announced alternative interpretation if adopted. Accordingly, the EPA Region 6 also is proposing to withdraw the SIP call issued to Texas that was published on June 12, 2015.
