Comparison: State vs. Federal
• Rules. Arkansas listed hazardous wastes parallel the federal list found at 40 CFR 261. See the national section LISTED WASTES for more information.
If a waste cannot be identified in one of the state hazardous waste lists, it still might be hazardous because it exhibits one or more characteristics of hazardous waste—ignitability, corrosivity, reactivity, or toxicity. See the national sections CHARACTERISTIC WASTE and HAZWASTE DETERMINATION (CLASSIFICATION) for additional information on hazardous waste identification and classification.
The EPA provides an exclusion (delisting) procedure, allowing persons to demonstrate that a listed waste from a particular generating facility should not be regulated as a hazardous waste. Arkansas has EPA authority to delist hazardous wastes. However, Arkansas does not provide for a state delisting program. To delist a waste in Arkansas, an applicant must first obtain a final delisting decision from EPA Region 6. See the state section DELISTING PETITIONS for more information.
• Administration and enforcement. ADEQ's Hazardous Waste Division administers and enforces the hazardous waste program in Arkansas.
