Underground Storage Tanks (UST) Update Rulemaking

In Minnesota, there are about 18,000 regulated USTs currently in use. The tanks are regulated by the UST program. UST regulations were first implemented by MPCA in 1988 primarily to prevent releases of petroleum products and hazardous substances from gas stations and other facilities into the environment. The regulations were subsequently amended to address federal language changes.

The existing underground tank rule is designed to prevent improper design, installation, use, maintenance, and closure of UST systems which includes the tanks, piping, and dispensers. There is a need to revise the UST regulations to incorporate U.S. Environmental Protection Agency changes to the UST program as well as to update outdated portions of the regulations due to changes in technology since the 1980s. Program knowledge gained during the last 20 years will be used to update and revise the regulations to make targeted changes to improve implementation and prevent UST releases.

The proposed revisions will consider the topics listed below:

  • adding secondary containment requirements for new and replaced tanks and piping;
  • adding operator training requirements for UST system owners and operators;
  • adding periodic operation and maintenance requirements for UST systems;
  • removing certain deferrals;
  • adding new release prevention and detection technologies;
  • updating codes of practice; and
  • editorial and technical corrections.

The MPCA may consider other things that come up, but only as time and resources allow.
