Wisconsin UST & LUST Overview
Wisconsin's regulatory program for petroleum storage tanks is divided between two agencies - The Department of Commerce and the Department of Natural Resources.
The Department of Commerce [exit DNR] is responsible for:
- Tank standards for both underground and aboveground tank systems
- Wisconsin's tank registration database
- Wisconsin's fund for reimbursement of environmental cleanup costs (PECFA)
- Oversight of cleanups at petroleum tank discharges that do not include high risk factors.
The Department of Natural Resources (DNR) is responsible for:
- Establishing investigation and remedial action requirements for contamination in the NR 700 series of environmental rules.
- Oversight of cleanups at petroleum tank discharges that include high risk factors. High risk factors are:
a) confirmed contamination in a water supply well above an NR 140 preventive action limit,
b) confirmed free petroleum product with a thickness of .01 feet or more,
c) groundwater contamination above an NR 140 enforcement standard within 1000 feet of a well operated by a public utility,
d) groundwater contamination above an NR 140 enforcement standard within 100 feet of any other water supply well,and
e) groundwater contamination above an NR 140 enforcement standard in fractured bedrock.
Jurisdiction of sites where risk factors have not yet been determined is with DNR. Jurisdiction of sites where petroleum contamination is co-mingled with non-petroleum contamination is also with DNR. Completed LUST site investigation reports should be sent directly to Commerce or to DNR, depending on the risk factors that are identified during the investigation. When site investigation reports are sent to Commerce, send DNR a copy of the cover letter so that we know the site jurisdiction has changed.
