About the Clean Air Technology Center

The Clean Air Technology Center (CATC) serves as a resource on all areas of emerging and existing air pollution prevention and control technologies, and provides public access to data and information on their use, effectiveness and cost. In addition, the CATC will provide technical support, including access to EPA’'s knowledge base, to government agencies and others, as resources allow, related to the technical and economic feasibility, operation and maintenance of these technologies.

RACT/BACT/LAER Clearinghouse

The CATC maintains an air pollution control technology database called the RACT/BACT/LAER Clearinghouse (RBLC). The RBLC provides data on air pollution control technology determinations made primarily by federal, state, local and tribal permitting agencies. The RBLC contains case-by-case air pollution control technology determinations that can help you identify appropriate technologies to mitigate or treat most air pollutant emission streams. The RBLC was designed to help permit applicants and reviewers make pollution prevention and control technology decisions for stationary sources of air pollution and includes data submitted by 50 states and territories in the U.S. on over 200 different air pollutants and 1,000 industrial processes.
