Leaks for petroleum storage tanks are one of the nation's leading causes of groundwater pollution.

To help address this problem, the Minnesota Legislature established the Petroleum Tank Release Cleanup Fund (Petrofund) which reimburses eligible applicants up to 90% of "reasonable and necessary" costs they incur in responding to a petroleum tank leak.

Petrofund Rules Notice

The rules governing the Petrofund program specify maximum environmental consultant and contractor costs to be reimbursed to eligible applicants for cleaning up petroleum contamination. To take inflation and/or deflation into account, mechanisms were drafted into the rules that allow for increasing or decreasing the maximum costs by increments of 10%. The dollar adjustment mechanisms are located in the following rule provisions:

  • Minn. Rule 2890.1900 provides for dollar adjustments to parts 2890.1300 to 2890.1600; and
  • Minn. Rule 2890.3900 provides for dollar adjustments to parts 2890.2600, 2890.2800 to 2890.3100, and 2890.3300 to 2890.3800.

Based on the rule criteria, the maximum costs found in these parts need to be increased by 10%. Based on the rule language, the new maximum reimbursement rates go into effect on July 1, 2017. The increases to the maximum reimburseable costs from each of the affected rule parts are identified in the following document.

The Petroleum Tank Release Compensation Board oversees the reimbursement program. It has five members: a petroleum industry representative, a person with claims adjusting experience, a public member, the Commissioner of the Pollution Control Agency, and the Commissioner of Commerce.

Statutes And Rules

The Petrofund Program is governed by Minnesota Statute 115C and Minnesota Rules 2890.

During the 2016 legislative session, the Petrofund 'sunset date' was extended from June 30, 2017 to June 30, 2022.


Abandoned Tank Program

Leaks from petroleum storage tanks are one of the nation's leading causes of groundwater pollution. To prevent further soil and groundwater contamination and to protect the safety of all Minnesotans, the state's Petroleum Tank Release Compensation Board (Petrofund Board) developed a new initiative to help landowners address the problem and cover the costs. In 2003 the Petrofund Board received authorization from the Minnesota Legislature to pay for the removal of abandoned underground storage tanks across Minnesota.
