  • Assessing Global Background Ozone Transport Pathways to the Northern Wasatch Front

    This project uses high-resolution modeling to explore how international and regional ozone is transported into the Northern Wasatch Front. By analyzing vertical transport patterns, the study will provide a mechanistic understanding of ozone levels in the area, supporting regulatory planning. The findings are crucial for refining air quality models and informing future policy demonstrations.

  • Utah Oil and Natural Gas Regulations

    In December 2023, EPA issued a final rule to reduce emissions of methane and other air pollutants from existing and new crude oil and natural gas operations, including oil and natural gas production, processing, transmission, and storage. The rule, referred to as Subpart OOOOb, includes new Standards of Performance, outlines new requirements to reduce VOC…

  • SmokeReadyUtah: Building smoke-ready communities through air quality monitoring, health messaging and targeted interventions

    SmokeReadyUtah provides support for underserved urban and rural communities to handle wildfire smoke. This program provides indoor and outdoor air quality monitoring along with enhanced health messaging and targeted interventions, providing communities and schools with the information they need to minimize their exposure to wildfire smoke. The project will be completed in March 2027 and…

  • Utah Summer Ozone Study (USOS)

    The National Oceanic and Atmospheric Administration (NOAA) is leading a large-scale campaign that will increase our understanding of ozone chemistry and emissions sources. During the Utah Summer Ozone Study (USOS), NOAA will be deploying two mobile labs and an aircraft that contains an exhaustive suite of instrumentation to measure the meteorology and ozone precursors that…

  • Marginal Conventional Well Closure Grant

    A subset of the Methane Emissions Reduction Program under the Inflation Reduction Act The U.S. Environmental Protection Agency (EPA) and Department of Energy (DOE) awarded the Utah Department of Environmental Quality’s (DEQ) Division of Air Quality (DAQ) $2.7 million to reduce methane emissions from marginal (low-producing) oil and gas wells in the Uinta Basin. Grant funds…

  • Northern Wasatch Front Serious Ozone SIP Technical Support Documentation

    The Utah Division of Air Quality (UDAQ) is currently developing the Northern Wasatch Front (NWF) Serious State Implementation Plan (SIP) for the 2015 8-hour ozone National Ambient Air Quality Standard. The following tabs contain the technical support documentation (TSD) pertaining to the development of the SIP and associated administrative rules. These are draft documents and…

  • VOCs Community Monitoring: Neighborhood Air

    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 Salt Lake, Bountiful, Woods Cross, Poplar Grove, and several…

  • 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…

  • Beehive Emission Reduction Plan

    Utah’s Beehive Emission Reduction plan to reduce statewide greenhouse gas emissions through EPA’s Climate Pollution Reduction Grant program Comprehensive Plan Engagement Opportunities The Comprehensive Plan will build upon the existing Priority Plan and extend our efforts to reduce emissions and improve air quality through 2050. This plan will include strategies to address emissions across all…

  • Charge Your Yard Incentive Program for Businesses

    The Charge Your Yard business program offers incentives for yard care businesses that primarily operate in Davis, Salt Lake, Tooele, Utah, and Weber counties to switch from gas-powered to electric yard equipment. Looking for the incentive program for residents? Charge Your Yard for Residents Yard care businesses:Get $3,000 to exchange your gas-powered equipment for electric!…

  • The Salt Lake Regional Smoke, Ozone and Aerosol Study (SAMOZA)

    The University of Washington, Utah State University and the University of Montana will conduct a detailed study of ozone (O3) and fine particulate matter (PM2.5) in the Salt Lake Valley (SLV). Using new VOC observations, plus existing measurements of NOx, CO and PM2.5, they will use a variety of analyses to understand O3 formation and…

  • 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…
