EPA to award up to $3.5 million for Clean Diesel projects in Colorado and Utah

Contact Information: 
Richard Mylott (

DENVER (September 30, 2020) – Today, U.S. Environmental Protection Agency (EPA) announced that state and local partners in Colorado and Utah will receive up to $3.5 million in grant funding to reduce harmful diesel emissions from school and transit buses, trucks and construction equipment. This announcement follows a press conference in Minnesota on Tuesday, in which EPA Administrator Andrew Wheeler announced over $73 million in grants and funding expected to be awarded to support numerous clean diesel programs and projects across the country at the state and local level. Over $50 million in Diesel Emissions Reduction Act (DERA) National Grants Program funding is expected to be awarded to implement projects aimed at reducing diesel emissions from the nation’s existing fleet of old, dirty engines and vehicles. Additionally, EPA anticipates providing approximately $23.5 million under DERA’s 2020 State Grants program to 48 states and four territories to implement their own diesel emissions reduction programs.

“EPA is proud to support our partners as they deliver cleaner air benefits to local communities across the country,” said EPA Administrator Andrew Wheeler. “New diesel engines operate cleaner than older engines, and for each dollar invested in clean diesel projects, communities get $13 in cumulative health benefits.”

“EPA’s DERA grants are a tried-and-true way to secure direct reductions of tailpipe emissions from older vehicles,” said EPA Regional Administrator Greg Sopkin. “We are pleased to extend these resources to partners who have identified opportunities to reduce human exposure to harmful pollutants and improve air quality in our communities.”

Under President Trump, the combined emission of criteria pollutants and their precursors dropped 7%. In the past three years, we saw the following drops in emissions of criteria and precursor pollutants: 

  • Nitrogen Oxides (NOx) ↓ 10 % 
  • Particulate Matter 2.5 (PM 2.5) ↓ 1 %
  • Sulfur Dioxide (SO2) ↓ 16%
  • Carbon monoxide (CO) ↓ 6%
  • Volatile Organic Compounds (VOC) ↓ 3%

Over the last three years during the Trump Administration, EPA will have awarded about $300 million in grants and rebates to modernize the diesel fleet and speed the turnover to cleaner on- and off-road heavy-duty trucks and equipment. Much of this assistance has been provided to help better protect areas of poor air quality and areas of highly concentrated diesel pollution, such as ports and distribution centers.

To support the Administrator’s clean air goals, the agency anticipates awarding these grants once all legal and administrative requirements are satisfied. So far in 2020, EPA has finalized awards for 41 clean diesel projects and programs. The agency anticipates completing additional awards throughout the rest of the year. The following grants have been finalized as of Monday, September 28:
