The America First Policy Institute (AFPI) has expressed support for new guidance from the Environmental Protection Agency (EPA) regarding Diesel Exhaust Fluid (DEF). The updated guidance was developed with input from industry leaders and workers. It aims to prevent unexpected equipment shutdowns, provide drivers and farmers more time to address issues, and help maintain schedules for freight and farm operations, while still protecting air quality.
Oliver McPherson-Smith, PhD, Vice Chair of Energy & Environment at AFPI, stated: “The administration’s policy of energy dominance means letting Americans use the machines that keep the country running without needless breakdowns. This common sense solution puts control back in the hands of operators and keeps equipment working. It helps transportation and energy do what they do best: create jobs and opportunity.”
Ambassador Kip Tom, Vice Chair for Rural Policy at AFPI, added: “When a tractor dies in the middle of planting or harvest, it’s not just an inconvenience—it can ruin a season’s work. By stopping sudden engine slowdowns, the EPA is helping the 1.9 million family farms that feed America, saving an estimated $727 million a year and keeping our producers on time, in the field, and on the road.”
The EPA’s DEF guidance is expected to benefit both transportation and agricultural sectors by reducing costly delays due to machinery breakdowns.
