EPA worked closely with regulatory partners to structure a risk-based air toxics program integrated between EPA and state, local and tribal agencies. While EPA has issued national standards to address air toxics risks, in many cases these risks are more appropriately addressed at the state, local and tribal level.

In February 2000, EPA created the Integrated Air Toxics State/Local/Tribal Program Structure Workgroup to obtain advice on how to structure a program encompassing federal, state, local, and tribal authorities. This workgroup was created under the Clean Air Act Advisory Committee, which EPA chartered in 1990 through the Federal Advisory Committee Act (referred to as "FACA" subcommittee workgroup). The group's final report was released in September 2000 and included recommendations for developing such a program, as well as critical issues which would need to be addressed in developing the program.

In September 2001, EPA issued the Workplan for the National Air Toxics Program and Integrated Air Toxics State/Local/Tribal Program Structure which provides an overview of the activities EPA has recommended or is planning to address during the technology and risk-based phases of the national program.
