  • Section IX, Control Measures for Area and Point Sources, Part A.31, Fine Particulate Matter

    Read about Utah DEQ’s regulatory interests in Section IX, Control Measures for Area and Point Sources, Part A.31, Fine Particulate Matter.

  • Wood-Burning Restrictions Go into Effect November 1

    The Utah Department of Environmental Quality’s Division of Air Quality (DAQ) reminds residents that wood-burning restrictions go into effect November 1, 2018, and urges Utahns to use online and mobile tools to monitor daily PM2.5 levels.

  • Request for Proposals (RFP):
    Science for Solutions Research Grant

    Opens: November 20, 2023Closes: February 2, 2024 The Utah Division of Air Quality (UDAQ) is seeking proposals for air quality research projects that help achieve UDAQ’s goals and priorities for the upcoming 2025 fiscal year (FY). See the following section for a description of 2025 FY goals and priorities. Coinciding with this announcement, UDAQ expects…

  • Air Toxics Lead and Asbestos Section (ATLAS)

    The ATLAS (Air Toxics Lead and Asbestos Section) deals with asbestos and lead-based paint. Learn about the Utah Division of Air Quality’s involvement with these topics here.

  • Asbestos Program

    Asbestos is a natural mineral fiber that is mined from the Earth. It was used in many common building materials for its strength and durability, insulation properties, and fire resistance. Today, asbestos materials look much different. Asbestos is found in many building materials, including but not limited to, drywall systems, textures, plasters, pipe insulation, metal…

  • ULend Program

    The ULend program is a collaborative approach for fixing compliance issues before they become a regulatory problem. The program focuses on small oil and gas producers who might not be able to afford the kind of expensive equipment that could help them identify and repair leaks early.

  • ULend Optical Gas Imaging Loan Program

    ULend is a partnership between Utah DEQ, TriCounty Health, and USU to make a leak detection camera available for use by Utah’s oil and gas industry.

  • Jordan Narrows Gap Ammonia Transport Study

    This study will provide key meteorological support for the chemistry observations taken during the upcoming 2018-­-2019 winter season that are focused on the ammonia transport and air mass exchange between the Salt Lake and Utah Valleys. Principal Investigators: Sebastian W. Hoch, Erik Crosman (UU) Funded by Science for Solutions Grant: $19,510

  • Wasatch Front Ammonia and Chloride Observations (WaFACO)

    The objective of this study is to define the spatio-temporal behavior of atmospheric ammonia (NH3) and hydrochloric acid (HCl) along the Wasatch Front across both summer and winter seasons. This objective will be accomplished through three tasks developed in consultation with UDAQ and the U.S. EPA. These tasks include 1) networked NH3 and HCl observations,…

  • Daily Wintertime PM2.5 Speciation at Hawthorne and Smithfield

    For the primary purposes of better validating Utah DAQ’s photochemical modeling, UDAQ will do more frequent speciation of wintertime PM2.5 filters. EPA’s Chemical Speciation Network (CSN) requirements specify either one-in-three or one-in-six day speciation of PM2.5 at three Utah locations (Hawthorne, Bountiful, and Lindon).

  • TRAX Air Quality Observation Project

    Utah’s Wasatch Front experiences poor air quality episodes during both summer and winter due to its unique weather, topography, and pollutant emissions. During winter, inversions trap unhealthy concentrations of fine particulate matter (PM2.5), while high pressure during summer leads to elevated ozone (O3) levels.

  • Aethalometer Study for Estimating Compliance
    with Wood-burning Ban

    The University of Utah Department of Chemical Engineering will collaborate with UDAQ to estimate the contributions of wood burning to wintertime PM2.5 levels using aethalometer data from four locations and from mobile aethalometer measurements. The goal of this study is to identify and understand levels of wood burning and compliance with wood-burning restrictions during the…

  • Composition of Volatile Organic Compound Emissions From Oil and Gas Wells in the Uinta Basin

    The Utah Division of Air Quality (UDAQ) is leading a new effort to improve estimates of the speciation of organic compound emissions from Uinta Basin oil and gas wells. Utah State University (USU) will work with UDAQ to collect and analyze pressurized gas and liquid samples from oil and gas well separators, as well as…

  • Bountiful City Dichloromethane and Formaldehyde Source Apportionment Study

    A source apportionment campaign, with an emphasis on determining the source of dichloromethane in Bountiful City, will be conducted between December 2018 and January 2019. Supporting measurements of PM2.5 concentration and composition will be provided as part of this effort. Principal Investigators: Kerry Kelly (UU), Jaron Hansen (BYU) Funded by Science for Solutions Grant: $80,067
