  • Clean School Bus Program

    As early as April 2022, up to $1 billion will be available nationwide for the purchase of alternative fuel and electric school buses through the Environmental Protection Agency (EPA). EPA may provide up to 100% of the cost for new replacement buses and charging or fueling infrastructure. Sign-up for alerts at EPA.gov/CleanSchoolBus FAQ’s Questions? Lisa…

  • Northern Wasatch Front Ozone Emissions Inventory

    Use the Interactive Inventory to explore different emission sectors and sources (SCCs). What is summertime ozone? You’re probably familiar with the Wasatch Front’s wintertime PM2.5 pollution, but Utah’s urban center also experiences harmful air pollution – ozone – during the summertime. Ozone is a highly reactive gas that causes damage to human lung tissue. Ground-level…

  • Particulate Chloride in the Urban Environment

    The University of Utah will conduct a study intended to significantly reduce uncertainties regarding the temporal, spatial, and particle size distributions of particulate chloride. Through source apportionment, the study will also identify the dominant sources of this important halogen. These results will provide important emission inventory constraints for future air quality modeling efforts performed by…

  • Impacts of the Great Salt Lake on Summer Ozone Concentrations Along the Wasatch Front

    The University of Utah is conducting a study to determine the meteorological factors that contribute to elevated surface ozone near the Great Salt Lake. The core task for this project is to evaluate from ozone observations and meteorological observations and model analyses the timing of buildup in ozone in the southern Farmington Bay region and…

  • Development of Top-down Hydrocarbon Emission from Oil and Gas Production in the Uintah Basin

    Utah State University and the University of Utah will use a method known as top-down emission estimation to refine volatile organic compound emissions from oil and gas production based on long-term surface level measurements of methane and hydrocarbons in the Uintah Basin. The objective of this project is to improve the Utah Division of Air…

  • Development of a WRF-based Urban Canopy Model for the Greater Salt Lake City Area

    Brigham Young University will conduct a two-year project that will utilize state-of-the-science meteorological modeling with land use descriptions of the Great Salt Lake area to characterize impacts of urban growth on local meteorological conditions. Model methodology and usage will be documented so air quality modelers can use existing or self-developed future results for additional urban…

  • Assessing Wintertime Ozone Prediction Sensitivity to Photochemical Mechanism

    Ramboll and the Utah State University – Bingham Research Center (BRC) will conduct a study to thoroughly investigate wintertime ozone prediction sensitivity in the Uinta Basin among two current photochemical mechanisms using a consistent modeling platform. Recent air quality modeling conducted by BRC using different modeling systems indicates that the Regional Atmospheric Chemistry Mechanism (RACM)…

  • Ethylene Oxide in Utah

    Ethylene Oxide (EtO) is an air toxic pollutant of emerging concern. At typical ambient concentrations, EtO is an odorless and colorless gas that is used in the sterilization of materials, such as medical equipment and spices. EtO is also an ingredient in chemical products, such as antifreeze, textiles, plastics, detergents and adhesives. EtO inhalation can…

  • Requirements Prior to Demolition

    DEFINITION: “Demolition Project” Utah Administrative Code (UAC) defines a “Demolition Project” as the wrecking, salvage, or removal of any load-supporting structural member of a regulated facility together with any related handling operations, or the intentional burning of any regulated facility. This includes the moving of an entire building, but excludes the moving of structures, vehicles, or…
