A Florida man has pleaded guilty for his role in a scheme that generated over $7 million in fraudulent Environmental Protection Agency (EPA) renewable fuels credits and sought over $6 million in fraudulent tax credits connected to the purported production of biodiesel.

According to court documents, Royce Gillham was the general manager of a biofuel company based in Fort Pierce, Florida, that produced and sold renewable fuel and fuel credits and claimed to turn various feedstocks into biodiesel. When reporting the number of gallons 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.

Gillham pleaded guilty to conspiring to commit wire fraud and to filing false claims. A sentencing date has not yet been scheduled. He faces a maximum penalty of five years in prison and a $250,000 fine for the conspiracy count. A federal district court judge will determine whether to accept the plea agreement after considering the U.S. Sentencing Guidelines and other statutory factors.

The IRS Criminal Investigation (IRS-CI) and EPA’s Criminal Investigation Division (EPA-CID) investigated the case.
