  • VOCs Community Monitoring: Neighborhood Air

    Project suspended until further notice due to instrumentation issues. This project aims to monitor volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) in underserved communities in Utah’s Wasatch Front. By conducting regular surveys using a mobile laboratory, the Division of Air Quality (DAQ) can gather data at the neighborhood level. Utah communities including North…

  • Utah Point Source Halogen Emissions

    HB 220 – Emissions Reduction Amendments, was passed during the 2023 Utah Legislature General Session. The legislation was subsequently signed into law by Governor Cox. The legislation’s applicability is limited to Box Elder, Davis, Salt Lake, Weber, Tooele and Utah counties and directs the Utah Division of Air Quality (DAQ) to: The legislation also directs…

  • WestSide AirSense: Empowering communities through enhanced PM monitoring

    We want to learn more about the air pollution in underserved neighborhoods on the west side of Salt Lake Valley. To do this, we’re using affordable air quality sensors in those areas to measure levels of PM2.5 and PM10 particles. We are developing air quality maps and alerts to provide instant, local air quality information.…

  • 2020 Statewide Emissions Inventories

    The air emissions inventory is one means used by the state to assess the level of pollutants released into the air from various sources. For the 2020 statewide emissions inventory, pollutants are estimated by emissions source category and the data are available below. Inventory Data The data posted on this site will include only the…

  • Volkswagen Settlement Vehicle Awards Through the DERA Option

    The Diesel Emissions Reduction Act (DERA) is a federal appropriation from the Environmental Protection Agency (EPA) aimed at decreasing harmful diesel engine emissions. For almost 20 years, the EPA’s DERA program has supplied funding to the Department of Environmental Quality (DEQ) to retrofit, repower, and replace older diesel vehicles and equipment with cleaner, more modern…

  • Improving Smoke Detection and Quantifying the Wildfire Smoke Impacts on Local Air Quality Using Modeling and Machine Learning Techniques

    Though it can be easy to tell that wildfire smoke has negative impacts on urban air quality, there is no tool to quantitatively measure wildfire impacts, nor to identify whether exceedance days are due to wildfire smoke or other emissions. The first scope of this work will develop a new plume rise model to estimate…

  • Improved Vegetation Data for the Biogenic Emission Inventory of Wasatch Front

    The goal of this project is to improve numerical predictions of regional ozone and aerosol distributions in the Wasatch Front by developing more accurate estimates of biogenic volatile organic carbon (BVOC) emissions for the urban areas within the Northern Wasatch Front. Specifically, this project will upgrade modeled MEGAN (Model of Emissions of Gasses and Aerosols…
