Utah continues to make significant progress towards understanding and addressing the causes of seasonal air pollution. Increased public awareness and legislative funding for research have provided important support for the Division of Air Quality (DAQ) in its ongoing efforts to reduce pollution, improve air quality, and protect public health. DAQ works to ensure that the …Read More
On Wednesday, Jan. 6, 2021, we sat down with Utah DEQ’s Division of Air Quality Monitoring Manager Bo Call to learn about how Utah’s air quality is monitored, how it’s improving and what it will look like this inversion season.Read More

Understanding Utah’s Air Quality Here is a quick overview of the chemicals we look for when monitoring the air and the sources of these pollutants. PM2.5 PM2.5 is the main component of Utah’s wintertime air pollution. PM2.5 refers to microscopic particles, or particulate matter (PM), that have a diameter of less than 2.5 micrometers—smaller than pollen …Read More
The U.S. EPA announced on Tuesday, Nov. 10, its intent to redesignate the Salt Lake City and Provo “non-attainment” areas to “attainment” for the 2006 24-hour fine particulate matter (PM2.5) National Ambient Air Quality Standard (NAAQS) under the Clean Air Act.Read More

The Utah Clean Diesel Program offers incentives for fleet owners to voluntarily reduce emissions from heavy-duty diesel engines. There are multiple funding opportunities available for eligible vehicles and equipment. Government and private fleet operators are encouraged to apply.Read More
Asbestos has been used since ancient times. In mid-century America, it was used in countless residential and industrial construction products. Learn more about the health risks and how to safely deal with asbestos on remodeling and demolition jobs.Read More
Utah State University scientists will improve estimates of the magnitude and composition of emissions from natural gas-fueled artificial lift engines in the Uinta Basin. Recent ambient air measurements have implicated natural gas-fueled engines as a large source of reactive organics, including formaldehyde, ethylene, propylene, and other compounds. The results from this project will allow Utah DAQ to better understand and model this source of ozone-forming pollution in the Uinta Basin and develop science-based, effective emissions reduction strategies for wintertime ozone.

The University of Utah will conduct vertical ozone profile measurements from ground level to the mid-stratosphere to develop a better understanding of ozone layers and evolution over Utah. Data collected by drones and balloons will provide information on the vertical distribution of ozone and nitrous dioxide (NO2) among other gases. This data will be used by UDAQ to inform policy and decision makers.

Wildfires can significantly enhance summertime ozone and aerosol concentrations, which can degrade air quality and have adverse effects on human health. While air quality has improved across much of the U.S., the Western U.S. has seen a recent increase in wildfire activity. This project will assess the contribution of regional fires and long-range smoke transport to poor air quality in the Salt Lake Valley. This study will also improve our understanding of how wildfires interact with urban plumes, improve air quality modeling capabilities, and guide the implementation of effective regulatory policies.

The Great Salt Lake Basin is meteorologically and chemically distinct from other regions in the U.S. It is subject to both persistent cold air pools in complex terrain that lead to winter air pollution and potentially large inputs of natural and anthropogenic sources of halogen species. This project will investigate the role of these halogen sources in regulating the severity of winter fine particulate matter (PM2.5). Results from this study will improve estimates of halogen emissions and enhance Utah DAQ’s understanding of winter PM2.5 chemistry.
