Comparison: State vs. Federal
• Rules. Colorado has developed geographically specific temperature standards for effluent discharges. These standards generally follow federal guidelines. The state's permit program is known as the Colorado Pollutant Discharge System (CPDS) program instead of the National Pollutant Discharge Elimination System (NPDES). Every CDPS applicant must report quantitative data for every outfall for both winter and summer temperatures.
• Administration and enforcement. CDPHE's WQCD is responsible for implementing and enforcing all thermal discharge regulations in Colorado.
WATER QUALITY STANDARDS
Under the Colorado Water Quality Control Act, the WQCD has classified and established surface water quality standards for specific state waters, including temperature criteria on a site-specific basis.
