Comparison: State vs. Federal
• Rules. Colorado follows the federal regulations for handling, marking, treating, storing, and disposing of polychlorinated biphenyls (PCB) and PCB items. Colorado also follows federal requirements for random inspections at solid waste landfills to detect PCB waste. See the national sections PCB MANAGEMENT and INSPECTIONS for additional guidance. Colorado has additional requirements to limit the concentration in biosolids.
• Administration and enforcement. EPA Region 8 is responsible for enforcing the PCB regulations in Colorado. CDPHE oversees the PCB restrictions for solid waste disposal facilities and biosolids.
5 CCR 1002-64.14 and 5 CCR 1002-64.15
No person is allowed to distribute, market, or apply biosolids unless the concentration of PCBs in the biosolids is less than 50 milligrams per kilogram on a dry weight basis. Monitoring of biosolids for PCBs is not a requirement unless it is specified by the CDPHE's Water Quality Control Division. See the state section NPDES PERMIT for additional guidance.
