Cleanup Contamination from Underground Storage Tanks

Press Enter to show all options, press Tab go to next option

Leaks pollute the ground, water and indoor air.

We require cleanup at current and historic underground storage tank (UST) sites. We issue permits for cleanup and tank removal. We also provide guidance on how to get started.

USTs store fuel and other liquids. Leaks can happen at gas stations, industrial sites, schools and hospitals. These sites are harmful to our health, the environment and our economy.
