• Rules. Maryland has adopted the U.S. Environmental Protection Agency's (EPA) Hazardous Waste Generator Improvements Rule, effective in Maryland as of May 3, 2021, which includes standards for generators accumulating hazardous waste on-site in tanks. To the federal tank rules, Maryland has added state requirements in connection with waste analysis and trial tests, returning a repaired tank system to service, inspections, and organic air emissions standards. Owners and operators of permitted hazardous waste tanks are responsible for paying permit fees.
