Grant awards will be capped at 50 percent of the incremental purchase or retrofit cost per vehicle, with a maximum total of $25,000 per vehicle. The incremental purchase cost is defined as the difference between a vehicle eligible for these grants and one powered by traditional fuels, such as diesel or gasoline.
Eligible vehicles must weigh 14,000 pounds or more and be fueled with compressed natural gas or liquefied natural gas. Bi-fuel vehicles are also eligible. For this first year, grant applications are due Feb. 1, 2013. Grants will be awarded in late March 2013.
