The Environmental Protection Agency (EPA) is urging machinery manufacturers to update their equipment to prevent shutdowns when diesel exhaust fluid runs out, Administrator Lee Zeldin said Monday.
Zeldin announced during a visit to the Iowa State Fair that EPA was issuing new guidance pressing equipment manufacturers to ensure vehicles already in use can receive software changes to prevent “sudden and severe power loss” from lack of diesel exhaust fluid.

EPA regulations already require that new diesel on-road trucks must be engineered to avoid power loss caused by a lack of diesel exhaust fluid. Often, vehicles experiencing diesel exhaust fluid problems are reduced within hours to going as slowly as five miles per hour, according to a press release. Such power reductions were likely meant to ensure compliance with the agency’s Tier 4 Emission standards.
"It is unacceptable that farmers, truckers, construction workers, and many other small businesses continually experience failures of diesel-powered equipment when they need it most—costing millions of dollars in lost productivity,” Zeldin said.
