Comparison: State vs. Federal
• Rules. Maryland's listed hazardous wastes include the federal list plus some additional sludges and residues, as well as materials that contain polychlorinated biphenyls (PCBs). See the national section LISTED WASTES for more information.
If a waste cannot be identified in one of the federal or 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.
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. MDE does not have EPA authority to delist Resource Conservation and Recovery Act hazardous wastes. However, EPA Region 3 encourages persons seeking a delisting to contact MDE for assistance. A copy of the petition must be sent to MDE. See the national section DELISTING PETITIONS for more information.
