• Rules. After a facility determines that its waste is a solid waste and is neither excluded from the definitions of solid or hazardous waste nor exempt from an applicable waste regulation, the owner and operator must determine if the waste is a hazardous waste. The first step in this process is determining if the waste is a listed hazardous waste. See the state sections HAZWASTE DETERMINATION (CLASSIFICATION) and LISTED WASTES for more information.
Whether or not a waste meets a hazardous waste listing description, the facility must still determine if the waste exhibits a characteristic of hazardous waste. Maryland follows the federal hazardous waste regulations at 40 CFR 261 that define a waste that exhibits the characteristics of ignitability, corrosivity, reactivity, or toxicity as a hazardous waste. See the national section CHARACTERISTIC WASTE for further guidance
• Administration and enforcement. MDE administers and enforces Maryland's rules for identifying the characteristics of hazardous waste.
