EPA Issues Draft Compatibility Guidelines for Ethanol

EPA developed proposed guidance clarifying how underground storage tank (UST) owners and operators can comply with EPA’s compatibility requirement (in 40 CFR §280.32) when storing certain biofuels, such as ethanol-blended fuels greater than 10 percent ethanol and biodiesel-blended fuels containing an amount of biodiesel to be determined. This proposed guidance is now available in the November 17,2010 Federal Register at
www.gpo.gov/fdsys/pkg/FR-2010-11-17/pdf/2010-28968.pdf. When final, the guidance will provide UST owners and operators with greater clarity in demonstrating compatibility of their tank systems with these fuels.

EPA is seeking input by Dec. 17, 2010.
