  • Methodology: Vehicle Miles Traveled Compared to 2-Stroke Lawn Equipment Use

    Comparison infographics for ChargeYourYard.utah.gov and the 2-stroke rule were created using the following methodology, using NOx + Volatile Organic Compounds emission for an average 2019 model year passenger vehicle in the Northern Wasatch Front geographic area. Emission Modeling System For Passenger Car: For Lawn & Garden 2-Stroke Equipment: Formulas Used

  • Reducing 2-Stroke Lawn Equipment Emissions

    Lawn care businesses: Get paid to go electric! Why it matters While our cars have gotten cleaner and cleaner in recent years thanks to modern emission controls and catalytic converters, 2-stroke engines have not kept pace with these improvements.  In fact, using a gas-powered leaf blower for one hour is the same as driving the…

  • Inland Port Monitoring

    The Utah Department of Environmental Quality (DEQ) has been tasked with establishing baseline conditions for stormwater and air quality within the statutorily defined area of Utah Inland Port (UIP) Authority. In addition, DEQ has been a part of land remediation and clean-up efforts at the North Temple Landfill Redevelopment site. Data collected by DEQ through…

  • Lead-Based Paint Program

    Lead in older homes Lead-Based Paint (LBP) was banned for use in houses in 1978, however, in houses built before 1978, there is a possibility that lead-based paint is still present. Dust from lead-based paint is the leading cause of lead poisoning in children which is a serious and preventable environmental health problem for both…

  • 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)…
