The U.S. Environmental Protection Agency (EPA) recently announced changes to diesel emissions system requirements, providing flexibility around diesel exhaust fluid (DEF) monitoring systems. The update is intended to reduce unnecessary equipment shutdowns caused by sensor failures, a concern that has impacted both transportation fleets and application equipment in recent years.

This change is expected to improve operational efficiency during the busy spring season, particularly for ag retailers managing tender trucks and application equipment. While compliance with emissions standards remains important, the added flexibility should help reduce downtime and improve reliability during critical field operations.
