Rules. The state has adopted by reference the U.S. Environmental Protection Agency's (EPA) Hazardous Waste Generator Improvements Rule, effective in Indiana as of December 26, 2019, which includes standards for generators accumulating hazardous waste on-site in tanks. Indiana follows the federal hazardous waste tank requirements for owners and operators of hazardous waste treatment, storage, and disposal facilities (TSDFs), including the organic air emissions standards.

In addition, TSDFs that use tanks must comply with additional permit application requirements and pay several state permit and facility fees. See the state section TSDF RESPONSIBILITIES to review these requirements and fees.

Administration and enforcement. The Indiana Department of Environmental Management's (IDEM) Compliance and Response Branch administers and enforces the hazardous waste tank rules in Indiana.
