Uinta Basin Particulate Matter

PM2.5 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 …

Inversions

Under 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 …

PM10 State Implementation Plans and Maintenance Plans

Nonattainment Areas In 1987, the EPA set new air-quality standards for PM10 of 150µg/m3 over a 24-hour period and an average of 50 µg/m3 annually. Utah was initially unable to meet the 24-hour standard and was required to prepare State Implementation Plans for Salt Lake and Utah County. Ogden City was designated nonattainment on September …
