What is the EPA Clean Air Markets Program?

The Clean Air Markets Program Division (CAMD), or simply "Clean Air Markets," answers scientific, general, policy, and regulatory questions about industry emissions. The program is designed to improve air quality and ecosystems by lowering outdoor concentrations of fine particles, mercury, ozone, and other significant air emissions. The most well-known of these programs are EPA's Acid Rain Program and the NOx Trading Programs, which reduce emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx)-- compounds produced by fossil fuel combustion.

TOXMAP's coal data includes all facilities in all programs covered in the AMPD's most recently completed calendar year whose primary or secondary fuel type is coal-related (e.g., Coal, Coal Refuse, and Petroleum Coke).
