have extended the waiver on the state’s biodiesel mandate by another month as
the biodiesel industry continues to work to correct problems with fuel being sold
in the state.
The St. Paul
Pioneer Press reported that representatives from the state’s
biodiesel industry met with officials Wednesday, Jan. 11, to ask for more time
to fix the problem.
Press reported that preliminary tests indicate that some batches of
biodiesel had high levels of glycerin, which caused gelling in cold weather and
clogged the fuel filters.
Industry officials say they don’t know where the bad batches
came from or how widespread the problem is, hence the request for more time.
The initial problem arose shortly after the state enacted a
mandate in October 2005 requiring that all diesel sold in the state be a 2
percent biodiesel blend. By November 2005, trucking and farming operations
across the state were reporting problems with clogged fuel filters and stalled
The state suspended the mandate in December 2005 and put
researchers to work on the problem. That suspension was scheduled to run out
Friday, Jan. 13. Now, it looks as though the industry will have until mid-February
to clean up the biodiesel supply.
