State Implementation Plan (SIP) - Regional Haze

To reduce haze, and to meet requirements of the Clean Air Act, U.S. EPA in April 1999 issued a regional haze rule aimed at protecting visibility in 156 federal areas. The rule seeks to reduce the visibility impairment caused by many sources over a wide area. Additional information about the regional haze rule can be found on U.S. EPA's website.
