National Park Service diesel vehicles on the North Carolina side of the Great Smoky Mountains National Park will be filling up with 50% biodiesel. This story in the Haywood County (NC) News says the biodiesel will go into about two dozen vehicles that burn 12,000 gallons a year:

“This biodiesel refueling project will help us achieve our long-term goal of stabilizing or improving air quality in the park,” said Dale Ditmanson, Park Superintendent. “We also see it as a great opportunity to lead by example as we host local school groups and millions of visitors from all across the country and world.”

The change is made possible through a couple of grants… one from the Clean Fuel Advanced Technology Project, managed by the North Carolina Solar Center and North Carolina State University… and one from specialty license plates in the state.
