Air Quality Levels Controlled by City Street Sweeping Efforts
By Doug Marsh, Street Superintendent
The City of Steamboat Springs area had been designated as “non-attainment” in1993 for the National Ambient Air Quality Standards for PM10 (airborne particulate matter with an aerodynamic diameter of 10 microns or less). The Air Pollution Control Division of the Colorado Department of Public Health and Environment and the City of Steamboat Springs developed standards for reducing PM10, thus reaching attainment, with a State Implementation Plan in 1996.
