ACTIVE UST FACILITIES are those where
there is at least one tank at the facility that is not closed in place or
removed and is regulated under Part 211, Underground Storage Tank
Regulations, of the Natural Resources and Environment Protection Act, 1994 PA
451, as amended (Act 451). There may be closed tanks and/or active
non-regulated tanks (such as heating oil tanks) at the facility.
CLOSED UST FACILITIES are those where all tanks at the facility that are regulated under Part 211 of Act 451 are closed. There may be non-regulated active tanks at the facility, such as heating oil tanks or tanks that are smaller than the regulatory cutoff. A CLOSED UST FACIILITY DOES NOT MEAN THAT THE RELEASE(S) ASSOCIATED WITH THE TANKS AT THE UST FACILITY ARE CLOSED. Please check the information under the leaking underground storage tank tab at the top of this page to see if the release(s) associated with the facility are open or closed.
