Comparison: State vs. Federal

Rules. Maryland follows the federal rules for the chemical alteration of corrosive wastes known as the elementary neutralization of hazardous wastes. See the national section NEUTRALIZATION OF WASTES for a summary of the federal requirements for neutralizing hazardous wastes. However, Maryland's exemption for ENUs from the hazardous waste treatment, storage, and disposal facility requirements is stricter than the federal counterpart since an ENU owner or operator is exempt unless the unit is used to treat waste from off-site.

Note: The waste may still be hazardous if it has other characteristic properties such as ignitability or toxicity. See the state section CHARACTERISTIC WASTE for more information.

Administration and enforcement. MDE administers and enforces the federal hazardous waste neutralization rules in Maryland.
