Uinta county / dust suppression 2026

The Federal Highway Administration awarded the Wyoming Department of Transportation $345,055 on January 23, 2026, under the Congestion Mitigation and Air Quality Improvement Program (CMAQ, CFDA 20.268) for dust suppression activities in Uinta County, Wyoming, with performance through March 31, 2029.

The project delivers application of chemical dust suppressant at various locations within Uinta County. The Wyoming Department of Transportation, functioning as a pass-through administrator, sub-awarded the funding to the County of Uinta (through the Uinta County Treasurer Division) on January 20, 2026, to execute the dust suppression work.

The CMAQ program provides flexible funding to state and local governments for transportation projects and programs that reduce transportation-related emissions in air quality nonattainment and maintenance areas for ozone, carbon monoxide, and particulate matter. Each state's apportionment is calculated based on a ratio specified in law, with a 2 percent set-aside for State Planning and Research. States with nonattainment or maintenance areas for fine particulate matter must dedicate 25 percent of CMAQ apportionment attributable to weighted population in those areas to projects targeting PM2.5 reductions, prioritizing benefits to disadvantaged communities or low-income populations where practicable. Funds are available for obligation for three years after the last day of the fiscal year for which they are authorized.
