Reasonably Available Control Measures (RACM) Process Ozone SIP
Utah’s Division of Air Quality examines and develops administrative rules to reduce ozone forming emissions of NOx and VOCs using a Reasonably Available Control Measures (RACM) approach, as required by the Clean Air Act. This page provides an overview of how this approach works and what emission reduction rules the state has already adopted. RACM…

#NoMowDays and Other Ways to Trim Your Grass and Your Emissions
Utah’s ozone and wildfires making it hard to breathe? Try #NoMowDays, switch to electric, upgrade your gas can, and mow later in the day for better air. Utah DEQ has some important tips that can help you reduce your emissions from an unlikely source–your gas-powered lawn mower.

Fireworks, Air Quality, and Wildfires, Oh My!
Fireworks are beautiful, but they also produce high concentrations of smoke and particulates (PM) that can harm our air quality and cause wildfires.

Dry Cleaning Using Perchloroethylene (perc) Rule and Guidance Documents
Perchloroethylene (PCE), also known as “perc,” is the most commonly used chemical solvent in dry cleaners. Dry cleaners in Utah using PCE are subject to federal and state regulations. 40 CFR 63 Subpart M sets national standards for reducing hazardous air pollutant (HAP) emissions, specifically PCE, from new and existing commercial dry cleaning facilities to…

Lead
Lead is a heavy metal found naturally in the environment and manufactured products such as lead-acid batteries, lead-based paints, leaded glass, solder, chemicals, and older water distribution systems with lead pipes, solders, and fittings. Lead is a persistent chemical that accumulates in soils, aquatic systems, sediments, and some plants, animals, and other organisms. Since 1990,…

Lead in Air
Lead is a toxic metal that was once used regularly in motor fuel, paint, ceramics, glassware, and other consumer products. The phase-out of leaded gasoline significantly reduced vehicle emissions and lead levels in the environment, but it is still used in some aviation fuels and used or produced in a variety of industrial processes. The…

Identifying and Quantifying the Impact of Wildfires and Dust Events on Utah’s Air Quality
Wildfires and dust storms are considered “exceptional events” in air quality modeling because they are not reasonably controllable or preventable, are caused by human activity that is unlikely to recur at a particular location, or are a natural event. Exceptional events can unpredictably increase concentrations of pollutants like particulate matter (PM) and ozone precursors, especially…

Improving Volatile Organic Compound Emission Estimates for the Uintah Basin
This study builds on last year’s effort to improve the speciation of volatile organic compound (VOC) emissions from oil and gas wells in the Uintah Basin. Better speciation profiles will yield a better emission inventory for the basin and will help focus emission reduction strategies. Principal Investigators: Trang Tran, Huy Tran (USU) Funded by Science…

Characterizing Air Quality Impacts from Exceptional Events along the Wasatch Front
This study, led by researchers at BYU, will use particulate matter (PM) sampling to identify regional dust sources that impact local air quality and public health, as well as model how dust sources might change in the future. Principal Investigators: Dr. Greg Carling (BYU) Funded by Science for Solutions Research Grant: $150,000

Improving WRF/CMAQ Model Performance using Satellite Data Assimilation Technique for the Uintah Basin
This study will test if satellite observations of vegetation and land use can be used to improve photochemical model performance in the Uintah basin. An improved model will help inform emission reduction strategies and regulatory action. Principal Investigators: Huy Tran, Trang Tran (USU) Funded by Science for Solutions Research Grant: $38,392

TRAX Air Quality Observation Project (Blue Line)
The TRAX air quality project continues to measure PM2.5 and ozone from TRAX light rail trains, and will add measurements to the Blue line. All data is publicly available and posted in near real-time on the MesoWest website. Principal Investigators: Daniel Mendoza, Logan Mitchell, John Horel, John Lin (UU) Funded by legislative appropriation: $44,000
