This story from Biodiesel Magazine says the money is from donors from all over the state:

The initial idea of the fundraiser was for donors to pledge five dollar amounts, signifying the approximate cost of a gallon of biodiesel. Iowans across the state, including biodiesel producers, marketers, and railroad companies all contributed to the effort.

Julie Vyskocil, a biofuels specialist with the Iowa Renewable Fuels Association, said the support received from the biodiesel industry and Iowans, demonstrating their concern for a fellow Iowa community in need, was overwhelming. “Donating biodiesel was a unique and practical way that we could help Parkersburg,” Vyskocil said. “Iowa is the leader in renewable fuels production and it seemed fitting to donate fuel produced in the state of Iowa that would be necessary in the rebuilding process.”

The money will go toward buying biodiesel that runs the equipment that continues to cleanup and rebuild the town. If you remember the photo on the left from right after the storm happened at the end of May, the town doesn’t look like that anymore. But there’s still plenty of work to do. It’s nice to know that biodiesel will be part of that effort.
