Shell Oil Company agreed to pay $4 million to resolve allegations that it received reimbursement from a state environmental cleanup fund even though it had also received payments from its insurers for the same cleanup sites. The alleged false claims by Shell and its joint venture, Motiva Enterprises, LLC, involved cleanup projects at more than a hundred gasoline stations both companies operated throughout Massachusetts. Under the state’s Underground Storage Tank Petroleum Product Cleanup Fund program (UST Fund), claimants must disclose if they sought reimbursement from another source, including insurance, for expenses they submit to the UST Fund. According to the Massachusetts Attorney General, Shell recovered payments from its insurers for past and future costs of remediating environmental damage at certain gas stations in Massachusetts, but did not disclose these payments to the UST Fund until February 2012.
