The General Manager of a company that produces and sells renewable fuel and fuel credits was sentenced on March 13 to serve 37 months in prison to be followed by a three-year term of supervised release for his role in a scheme that generated over $7 million in fraudulent EPA renewable fuels credits and sought over $6 million in fraudulent tax credits connected to the purported production of biodiesel.
Royce Gillham worked at a biofuel company based in Fort Pierce, Florida, that claimed to turn various feedstocks into biodiesel. However, when reporting the number of gallons they produced to the IRS and EPA, Gillham and his employer vastly overstated their production volume in an effort to generate more credits. When auditors sought more information from the company, Gillham and his co-conspirators provided false information about their fuel production and customers.
