Clean Air Interstate Rule Program

The CAIR program addresses interstate pollution by capping annual NO_X and SO₂ emissions from applicable electric generating units in 27 states, including Texas, and the District of Columbia. The TCEQ allocates CAIR NO_X allowances and the U.S. Environmental Protection Agency (EPA) handles all other CAIR rule requirements. Participation from applicable electric generating units is mandatory.

On August 21, 2012, the U.S. Court of Appeals for the District of Columbia Circuit issued an order vacating CSAPR. The court also ordered the EPA to continue to administer CAIR while the EPA works to replace CAIR.

Rules related to the CAIR Program are found in 30 TAC Chapter 101, Subchapter H, Division 7.
