Cross State Air Pollution Rule
The Cross-State Air Pollution Rule (CSAPR) is a federal implementation plan to reduce the interstate transport of air
pollutants across state boundaries. The federal CSAPR programs replace the Clean Air Interstate Rule programs
(CAIR). A December 2008 court decision kept the requirements of CAIR in place temporarily, but directed EPA to issue
a new rule to implement the Clean Air Act requirements concerning interstate transport of air pollution. The CSAPR
is designed to implement these Clean Air Act requirements and respond to the court's concerns. CSAPR takes effect
January 1, 2015; CAIR will be implemented through the 2014 compliance periods, and then replaced by the CSAPR.
Because the CAIR programs no longer exist, the Division of Air Quality intends to repeal the CAIR provisions set
forth in 45CSR39, 45CSR40 and 45CSR41 during the 2016 session of the West Virginia Legislature.
