Comparison: State vs. Federal
• Rules. Colorado follows the federal regulations for identifying and classifying hazardous waste, but its waste determination rules are also more stringent than the federal rules in that Colorado has not adopted all the solid waste exclusions that are available under the federal rules, such as the conditional exclusions from the definitions of solid and hazardous waste for solvent-contaminated wipes and the hazardous waste exclusion for carbon dioxide streams in geological sequestration activities. The state also recognizes an additional exclusion from the solid waste definition pertaining to inert materials and not found under the federal rules. Rather than adopt the federal rules that conditionally exclude cathode-ray tubes (CRTs) from the definition of solid waste, Colorado allows CRTs to be managed under the state's universal waste regulations. See the state section UNIVERSAL WASTES for more information.
• Administration and enforcement. The hazardous waste determination rules in Colorado are administered and enforced by the Hazardous Materials and Waste Management Division of the Colorado Department of Public Health and Environment (CDPHE).
