Local Emergency Planning Committees (LEPC) were established by the Federal Emergency Planning and Community Right-To-Know Act, as Title III of the Superfund Amendments and Reauthorization Act of 1986. This legislation requires local planning by businesses and response agencies whenever hazardous materials are involved.

The purpose of the LEPC is to encourage and support hazardous materials emergency planning efforts at the state and local levels and to provide the public and local governments with information concerning potential chemical hazards present in their communities.

Any business which uses, manufactures, stores or transports hazardous materials is required to have procedures for safe handling of these materials as well as emergency response procedures. Fire departments and other response agencies are also required to have procedures for hazardous materials spills.​
