DERA provides funding to encourage technoloies that reduce emissions from diesel vehicles and equipment by up to 90 percent.
It is a program with strong bipartisan support. Authored by a Republican, it passed in 2005 with a 92-to-1 vote in the Senate.
The legislation had “the strong support of the Bush Administration,” the companies and trade associations wrote in their letter to Pruitt. The George W. Bush administration requested funding for the program in every year’s budget after it was first authorized. And it is the “only EPA program for which all regions sought additional funding,” the group said.
