Clean Air Interstate Rule Program
The CAIR program addresses interstate pollution by capping annual NOX and SO2 emissions from applicable electric generating units in 27 states, including Texas, and the District of Columbia. The TCEQ allocates CAIR NOX allowances and the U.S. Environmental Protection Agency (EPA) handles all other CAIR rule requirements. Participation from applicable electric generating units is mandatory.
Rules related to the CAIR Program are found in 30 TAC Chapter 101, Subchapter H, Division 7.
