Files in this subseries relate to the Colorado Water Pollution Control Commission (WPCC) whose name was later changed to the Water Quality Control Commission (WQCC). Original folder titles used these acronyms interchangeably as they refer to the same commission. For the convenience of researchers, files were rearranged alphabetically followed by any files that began with dates or numbers, listed numerically under a general WPCC/WQCC acronym. The Colorado Water Quality Control Commission was created in the 1960s to regulate pollutants in the state's surface and groundwater. The commission develops water quality standards based on the policy recommendations of the state legislature as authorized by the Colorado Water Quality Control Act. Norman Evans, director of ERC/CWRRI, was a member of the commission from 1966 until the 1980s. Files in this subseries contain meeting minutes, information on statewide water quality issues, case histories involving municipal sanitation and industrial pollution, federal and state legislation, river data on major Colorado watersheds, pollution standards and classifications, commission regulations, and water quality management plans for several local governments, among other miscellaneous files.
