American Farm Bureau Federation President Zippy Duvall commented recently on the Environmental Protection Agency’s announcement that it will revise Diesel Exhaust Fluid (DEF) guidelines for manufacturers of heavy trucks and off-road equipment. Manufacturers will be directed to update software in equipment that uses DEF to prevent them from losing power.

“Farm Bureau thanks the EPA and Administrator Zeldin for their common-sense approach to heavy trucks and off-road equipment that use Diesel Exhaust Fluid. When a vehicle runs out of DEF or there is an error in the software, it loses power, causing delays that could be the difference between getting a crop harvested or animals to their destination.

“EPA’s decision to grant a grace period to make repairs or refill DEF is the right thing to do. It keeps commerce moving and farmers in the field.”
