Many businesses use storage tanks in their day-to-day operations to store liquids or gases, such as flammable and combustible petroleum products and hazardous substances. There are two types of storage tanks based on how they are installed -- underground storage tanks and aboveground storage tanks.
Tanks made of steel can corrode and leak over time, and any tank can impact the environment and affect Hoosiers if it is not properly installed, operated, and maintained. Leaking tanks and their associated piping can release dangerous vapors into buildings or contaminate soil, surface water, and ground water.
Federal and state regulations for underground storage tanks (USTs) and aboveground storage tanks (ASTs) promote the safe storage and handling of flammable and combustible liquids to minimize the possibility of releases and to reduce fire hazards. The Office of Land Quality (OLQ) helps businesses understand what IDEM regulates and how to achieve compliance. OLQ also enforces Indiana’s UST regulations, ensures adequate cleanup of contamination from leaks and spills, and manages a registration database for ASTs.
Tank owners and operators who meet their environmental responsibilities will safeguard our environment, protect public health, and protect their assets by avoiding the cleanup and liability costs associated with contaminated sites.
OLQ is currently updating several processes, rules, and forms associated with storage tank activities, so the content of this website is subject to change. Please contact IDEM if you have any questions about the information within.
