Underground Storage Tanks (UST)

According to the EPA, an underground storage tank system (UST) is a tank or connected piping that is at least 10% underground. EPA UST regulations aim to prevent releases and leaks of hazardous material from underground storage tank systems. The laws typically apply to UST systems that store petroleum, yet other specific hazardous substances are covered.

Deciding whether to replace a fuel storage tank requires sophisticated, cost-benefit analysis. At the Institute for Environmental Assessment, Inc. (IEA), our consultants provide underground storage tank removal design and soil testing, management, and monitoring services to minimize the risk of spills during removal. IEA also provides assistance with required Minnesota Pollution Control Agency (MPCA) coordination and tank closeout documentation.

IEA assists clients with the management of underground and aboveground storage tanks (UST & AST). Our tank removal design, soil testing, and removal support services closely prepare and monitor removals to help our clients comply with UST regulations.
