Three major oil companies have agreed to repay Minnesota $7.4 million after an investigation found they tapped a state fund to pay for underground tank cleanups while also getting reimbursed by their insurance carriers, the state Commerce Department said Tuesday.
The department said Chevron, ExxonMobil and ConocoPhillips agreed to return the money to the Petroleum Tank Release Cleanup Fund, also known as the Petrofund, that helps pay for cleaning up property contaminated by underground storage tanks.
"The big oil companies, in essence, double-dipped by getting Petrofund dollars as well as the insurance proceeds," Commerce Commissioner Mike Rothman said in an interview.
The companies denied any wrongdoing, including misrepresentation, saying they were "factually and legally entitled" to payments from the state fund regardless of any insurance recoveries, according to the settlement.
Chevron spokesman Brent Tippen rejected the commissioner's claim that the company double-dipped, saying in an e-mail that the company acted in good faith.
Phillips 66, which recently was spun off from ConocoPhillips, agreed to pay the most, $4.9 million. Chevron agreed to pay $1.97 million, and ExxonMobil $550,000. Phillips 66 said only that it had resolved the matter. ExxonMobil did not respond to a request to comment.
Rothman said Petrofund officials, who are part of the Commerce Department, first suspected that companies were getting double reimbursements for cleaning up property polluted by leaking gas station storage tanks.
Those concerns triggered a 15-month department investigation of payments ranging from 1988 to 2012, he said.
