Underground Storage Tanks

Many businesses utilize underground storage tanks for products such as gasoline, diesel fuel, and other liquid chemicals. Environmental damages and safety risks can result from improper installation and maintenance as well as degradation of the tanks over time. The design, construction, installation and maintenance of underground storage tanks that store regulated substances are licensed under Part 211, Underground Storage Tank Regulations, of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended (NREPA) by the Michigan Department of Licensing and Regulatory Affairs (LARA). Those underground storage tanks that require corrective actions due to a release are regulated under Part 213, Leaking Underground Storage Tanks, of NREPA by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). This data layer shows the locations of known underground storage tanks in Michigan including those that have a record of a release. This data is regularly updated.
