Minnesota Extends Biodiesel Waiver Until Feb. 10

innesota officials are giving the state’s biodiesel industry another month to fix problems with the fuel that led to clogged fuel filters this winter, the Associated Press reported Thursday.

The state’s Commerce Department said a state law requiring diesel fuel to contain at least 2% biodiesel will not go back into effect until Feb. 10, extending an emergency waiver that would have expired Friday, AP reported.

The soybean-based fuel is blamed for clogging fuel filters, particularly in cold weather. (Click here for previous coverage.)
