Comparison: State vs. Federal

Rules. Colorado follows the federal rules for surface impoundments, including the organic air emissions standards. It has additional requirements for interim-status surface impoundments regarding certifications. In addition, owners and operators of hazardous waste treatment, storage, and disposal facilities (TSDFs) that use surface impoundments must comply with additional permit application requirements and pay several state permit and facility fees. See the state section TSDF PERMITS for more information.

Administration and enforcement. CDPHE's Hazardous Materials and Waste Management Division administers and enforces the surface impoundment requirements in Colorado.
