Under the Renewable Fuel Standard the EPA has imposed a ‘buyer beware’ approach to the purchase and sale of RINs. This creates a liability for any buyer of RINs, making them responsible for purchases of invalid RINS, even if done inadvertently. The liability includes the replacement cost of invalidated RINs as well as civil fines and penalties imposed by the EPA. The EPA has already prosecuted millions of US$ worth of fraudulent RIN transactions, yet fraud continues to be a significant risk. Parhelion has created a solution to this risk.
