In 1971, the local governments of the various municipalities and communities of Pueblo County, as well as other local agencies such as school districts and water works, entered into a cooperative arrangement through the mutual adoption of articles of association. This partnership became known as the Pueblo Area Council of Governments (PACOG). In 1979, PACOG established the Environmental Policy Advisory Committee (EPAC) as a citizens' advisory committee on environmental policy matters to both PACOG and local elected officials. EPAC was formally organized in 1980 pursuant to Title 40 of the Code of Federal Regulations, Part 25 (40 CFR Part 25). It was created in response to the U.S. Environmental Protection Agency's regulations for public participation through advisory committees receiving federal dollars under the Resource Conservation and Recovery Act, the Safe Drinking Water Act, or the Clean Water Act.
