WASHINGTON, D.C. - Today, during a Senate Environment and Public Works Committee hearing, U.S. Senator Pete Ricketts (R-NE) advocated for legislative efforts providing regulatory relief and clarity for diesel engines operating in cold-weather environments.
"Diesel engines are an important part for many vehicles, including in the agricultural industry. In states like Nebraska, where we experience cold … and highly variable weather, these systems face additional operational challenges," said Ricketts. "Nebraska agriculture producers report that emissions-related issues, particularly with DEF systems, account for a majority of their machinery repairs… A major grievance is that when a DEF sensor fails or the system malfunctions, it often triggers 'limp mode,' where a tractor or combine loses power and speed, causing critical delays during planting or harvesting."
"I applaud the Trump administration's EPA who has recognized this challenge by publishing guidance that allows greater flexibility and longer warning periods before derates occur," said Ricketts.

The witnesses were Ryan Anderson, Commissioner, Alaska Department of Transportation and Public Facilities; Todd Fornstrom, President, Wyoming Farm Bureau Federation; and John Walke, Director for Clear Air Programs and Senior Attorney, Natural Resources Defense Council.
