Clean Air Interstate Rule Program

This market-based cap-and-trade program is for applicable electric generating units in Texas and other states.

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.

Hot TopicThe 2013 New Unit Pool Allocations and the 2017 General Pool Allocations are available under the Allocations section.

Hot TopicOn 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. Exit the TCEQ
