California Approves B20 Biodiesel in Underground Storage Tanks

Effective October 1, California becomes the final state to approve the storage of biodiesel in underground storage tanks. Through a concerted effort of the National Biodiesel Board (NBB), the California Advanced Biofuels Alliance, and several member companies the last major hurdle regarding the storage of biodiesel in underground storage tanks has satisfied the State Water Board. NBB CEO, Donnell Reghagen stated that the amended regulations allow for double-walled UST owners and operators the ability to store B20 to comply with regulations. 

“This is a major victory towards biodiesel’s mainstream integration into the California fuel supply,” said Rehagen. “We recognize the huge potential for biodiesel to supply California with a better and cleaner fuel and applaud state regulators for working closely with us to clear this final hurdle that will allow for more low-carbon biodiesel to make its way to consumers and fleets all across the state.”

The use of biodiesel will make use of the state’s Low Carbon Fuel Standard and further reduce greenhouse gases. The California Air Resources Board states that the use of biodiesel will reduce the amount by 50 percent, and as much as 80 percent when compared to petroleum.

Concerns were raised that any degradation of UST materials could allow diesel fuel to compromise the water supply despite that it degrades quickly in water.The California State Water Resources Control Board amended the regulations on August 6th stating that diesel containing up to B20 meets the standard for ASTM standards for double-walled USTs. 

“This change represents a huge milestone for consumers in California, who will now have increased access to B20 in a state where protecting the environment is greatly valued,” said Tyson Keever of biodiesel producer SeQuential and Crimson Renewable Energy. “Our company is driven to make a positive impact on reducing carbon emissions, to stimulate local economies, and to reduce dependence on fossil fuels, and this new regulation will amplify our ability to do all three.”
