Utah Clean Diesel Program

Diesel engines carry millions of children to school each day, power the movement of goods, help produce the food that we eat, help construct the homes and buildings in which we live and work, and help build the roads on which we travel. While diesel engines provide mobility and are critical to the nation's economy, exhaust from diesel engines contains pollutants that negatively impact human health and the environment.

Diesel engines are a major source of pollution. Specifically, they emit particulate matter (PM); nitrogen oxides (NOx)—which contribute to the formation of both PM2.5 and ground-level ozone; hydrocarbons (HC); and air toxics. These pollutants contribute to poor air quality in Utah and can cause serious health problems, especially for children, the elderly, and the chronically ill. Fortunately, many cost-effective solutions are available today that can dramatically reduce pollutants from diesel exhaust.

The Utah Division of Air Quality (UDAQ) established the Utah Clean Diesel Program to promote diesel emission reduction strategies. Since 2008, over $12 million in state and federal grants have helped public and private fleet owners in Utah reduce emissions from their diesel vehicles and equipment.

The UDAQ is accepting applications for eligible projects.
