New Air Pollution Laws have been developed for Utah, according to a Salt Lake Tribune article today.
Current standards allow communities a certain number of days when air exceeds 65 micrograms of these fine particles per cubic meter before the EPA requires added pollution cuts. The new standard would reduce the daily trigger to 35 micrograms of PM2.5 per cubic meter of air.
Every Utah county meets the current standard. But, based on air-pollution data collected by the state over the past three years, 10 counties - Cache, Box Elder, Weber, Davis, Morgan, Salt Lake, Summit Tooele, Utah and Juab - would exceed the 35-microgram limit.(The Tribune has nicely provided a context at the end of its article for PM2.5:
PM 2.5 PARTICLES are 1/40th the width of a human hair.
PM 2.5 is produced mainly from engines in cars and trucks.
FEDERAL OFFICIALS say tough new standards for the pollutant will prevent about 17,000 premature deaths each year.)
Many environmentalists, though, feel the standards need to be even more tough.

The bottom line is that not only do standards need to be strengthened, but more education is needed so that people significantly reduce their dependence on automobiles and revert to alternative forms of energy and transportation.
