Minnesota regulators have temporarily suspended a new and more stringent standard for biodiesel use due to shortages of the product, says the Star Tribune.
On May 1, the amount of biofuel that must by state law be blended into diesel jumped from 10% to 20%. But production at one of the state's two main biodiesel plants — Minnesota Soybean Processors in Brewster, MN — has been shut down since earlier this month for a turnaround.
With the plant idled, the Minnesota Department of Commerce on Monday issued a "waiver" for B20 — diesel that contains 20% biofuel by volume — until June 30.
