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 Salt Lake, Bountiful, Woods Cross,

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: Complete an air emissions inventory of point sources that emit halogens

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. Interested community members can get involved

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 latest version of the 2020 Emissions Inventory.

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 alternatives. Utah has chosen DERA as one of

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 the sources of PM2.5 in the SLV during the summertime season. In addition, they will conduct photochemical modeling and statistical/machine learning analyses to improve our understanding of O3 photochemistry. We expect to gain significant new policy-relevant insights on what controls high concentrations of O3 in the SLV during both smoke-influenced and non-smoke conditions.

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 the plume injection heights for larger wildfires, which will improve simulations of smoke transport and downwind air pollution concentrations. The second scope of this work is to use CTM (chemical transport model) ensemble simulations to determine wildfire smoke contributions to local air quality using source apportionment techniques. The last scope of this work is to develop a fast-response tool to identify federal standards (NAAQS) exceedance days with large contributions from wildfire smoke.

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 from Nature) BVOC emission estimates by analyzing high-resolution satellite imagery using machine learning, object-based classifications that are calibrated and assessed by field observations. Such techniques have already successfully been applied in Texas and California. These techniques will improve MEGAN landcover inputs for the Wasatch Front region including time-varying Leaf Area Index (LAI), growth form fractions (tree, shrub, crops, herbaceous plants) and tree species composition (e.g., relative abundance of oaks, poplars, pines, spruce, etc). The benefit of this project will be an improved MEGAN emission model for the Wasatch Front that is available for use in air quality models that are critical for our scientific understanding and the development of effective regulatory strategies.
