Folsom-Natoma St. Air Monitoring Station, Folsom, California

Folsom-Natoma St. is an air monitoring station located at 50 Natoma Street in Folsom, California, within Sacramento County. Operated by the Sacramento County Air Pollution Control District (APCD), this station contributes to the unofficial Photochemical Assessment Monitoring Stations (PAMS) network, focusing on ozone precursor monitoring. The station operates under the regulatory framework of the U.S. EPA's Ambient Air Quality Standards (NAAQS) and the Air Quality System (AQS). As part of the PAMS network, it measures criteria pollutants and volatile organic compounds (VOCs) to support ozone formation studies. The station's siting in an urban area ensures representative sampling of population exposure. Environmental monitoring at this station supports local air quality management and public health protection. Data collected helps assess compliance with federal standards and informs emission reduction strategies in the Sacramento region. The station's continuous operation provides valuable long-term trends for policy development.

The Folsom-Natoma St. station monitors air quality in the Sacramento Valley, an area with periodic ozone exceedances due to vehicle emissions and meteorological conditions. As part of the PAMS network, it measures ozone precursors like VOCs and nitrogen oxides, which are critical for understanding photochemical smog formation. The station's urban location provides representative data for population exposure assessment.
