This week’s blog is from 2015 and highlights the popular woodstove exchange program. Last week, The Utah Department of Environmental Quality (DEQ) released the 2020 registration schedule for the overwhelmingly popular grant program to convert operating wood-burning fireplaces to cleaner-burning natural gas or electric. Online registration will take place across the Wasatch Front and Cache …

This month, researchers finished gathering data for the Wasatch Front Ammonia and Chloride Observations (WaFACO) study. This study hopes to find the sources and role that ammonia plays in the formation of air pollution in Northern Utah.
Read MoreThe Uinta Basin lies in the northeast corner of Utah and is bounded on the north by the Uinta Mountains, on the south by the Tavaputs Plateau, on the west by the Wasatch Range, and on the east by elevated terrain that separates it from Piceance Basin in Colorado. Duchesne and Uintah Counties occupy most …
Read MorePM2.5 UDAQ began monitoring PM2.5 in Vernal in December 2006. During the 2006-07 winter season, PM2.5 levels exceeded the new PM2.5 health standard that became effective in December 2006. The PM2.5 levels in Vernal were similar to other areas in northern Utah that experience wintertime inversions. The State of Utah is in the process of …
Read MoreWhile it might not seem like hair spray, carpet cleaner, or air fresheners contribute to Utah’s PM2.5 problem, they do.
Read MoreSerious Area PM2.5 State Implementation Plan (SIP) Development PM2.5 PM10 Current Air Quality PM2.5 Trend Plots Utah Clean Air Partnership (UCAIR) Particulate matter (PM), also known as particle pollution, is a complex mixture of small solid particles and liquid droplets in the air. Some particulate matter, like soot, smoke, dust, or dirt, is large enough …
Read MoreUnder normal atmospheric conditions, air is warmer near the ground and colder at higher altitudes. In a temperature inversion, the situation “inverts,” and cold air at the surface gets trapped under a layer of warmer air. During the winter, snow-covered valley floors reflect rather absorb heat, preventing the normal vertical mixing of warm and cold …
Read MorePM2.5 particulates are fine, inhalable particles or droplets with a diameter of 2.5 microns or smaller. These fine particulates, which are about 30 times smaller than the width of a human hair, can travel deeply into the lungs and cause both short-term and long-term health effects. While larger PM10 particulates can compromise respiratory and cardiac …

Read MoreNonattainment designation is determined by the EPA when an area or areas within a state persistently exceed the National Ambient Air Quality Standards. The EPA has designated "nonattainment areas" for Particulate Matter having an aerodynamic diameter of 2.5 microns (μm) or less (PM2.5). The three EPA designated areas include: Provo, Utah Logan, Utah and Franklin …

The Department of Environmental Quality and its divisions and boards are committed to using the public notice and comment process to improve the decisions they make.

Read MorePM2.5 data has been collected at most monitoring stations since 2000. Like PM10, maximum values also tend to occur during wintertime inversions. Also like PM10, trends are somewhat difficult to evaluate because weather plays such a large role in the data collected from year-to-year. This is why the standard is evaluated over a three year …
