As air quality continues to be a focus across Colorado, Weld County is sharpening its efforts in 2025 to support cleaner air and informed communities. Through partnerships, public outreach and policy analysis, Weld County’s Air Quality Program is taking proactive steps to address key environmental challenges and help residents stay engaged in ongoing air quality conversations at both the local and state levels.

What We're Working On

Weld County’s Air Quality Program is focused on:

  • Sharing simple, helpful information about air and environmental health.
  • Letting residents know when and how they can take part in local and state air quality decisions.
  • Promoting discounts and programs, such as those for electric lawn tools.
  • Working with scientists, schools and other governments to find real solutions.
  • Applying for grants to fund future air quality work.

 

This Year’s Focus: Ozone, Air Toxics and Nitrogen

Ozone: The Front Range, including Weld County, is not currently meeting federal ozone health standards. That means state and local agencies are actively evaluating control strategies to reduce ozone-forming pollutants. In addition, the U.S. Environmental Protection Agency (EPA) is reviewing the national ozone standard. We’re working with others to explore ways to reduce ozone pollution and keeping up with new research that helps explain what’s driving the problem in our region.

Air Toxics: Colorado is starting a multi-year effort to create rules for air toxics including benzene and formaldehyde. Weld County’s air quality team want to make sure these rules protect people’s health, are based on good science and help residents understand what these substances mean for their health.

Nitrogen: Weld County is part of a statewide effort to understand how nitrogen pollution from farms and cars affects nature, air quality, and visibility. We’re looking at how nitrogen contributes to other air issues like ozone fine particulate matter (PM2.5).

Staying Involved

As lawmakers consider new environmental bills this year, Weld County will follow the discussions, share our perspective, and let you know how you can share yours. The air quality team serves as a technical resource to help our local leaders understand how proposed changes might affect the county and support informed decision-making.

By sharing knowledge and working together, we’re making sure Weld County has a strong voice in shaping cleaner air and healthier communities.
