EPA Proposes Guidance for Underground Storage Tanks

November 18, 2010

As part of its commitment to help ensure that biofuels, such as ethanol and biodiesel, are safely stored in underground storage tanks (USTs), the U.S. Environmental Protection Agency (EPA) released draft guidance for UST owners and operators who wish to store these fuels.  EPA is requesting comments on the proposed guidance that clarifies how an UST owner or operator can comply with the federal compatibility requirement for UST systems storing gasoline containing greater than 10 percent ethanol, and diesel containing a percent of biodiesel yet to be determined.  After reviewing comments, EPA intends to issue the final guidance in early 2011.
