Summary

The Environmental Protection Agency (EPA) is proposing to extend the attainment dates for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM10) in Salt Lake and Utah Counties, Utah, due to their continued failure to meet the National Ambient Air Quality Standards (NAAQS) for PM10.
