The regulatory agency that oversees underground petroleum storage tanks in Indiana is the Office of Land Quality, of IDEM. There are two agencies that oversee aboveground storage tanks: IDEM and the Indiana Department of Homeland Security, State Fire Marshal Office. There also can be local municipal agencies that will have jurisdiction. The regulations and responsibilities of each agency can be very confusing. With aboveground outside or inside storage of flammable and combustible liquids, it is recommended to contact each agency to verify you are currently complying with their applicable regulations.
