Livermore - Old 1st St. is an air monitoring station located at 2614 Old 1st St. in Livermore, California, United States. It is part of the California Air Resources Board (CARB) monitoring network, which supports federal and state air quality programs. The station is operational and contributes to the region's environmental monitoring infrastructure. The station operates under the regulatory framework of the U.S. EPA's Air Quality System (AQS), which sets standards for criteria pollutants such as ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide. As part of CARB's network, it likely measures multiple pollutants to assess compliance with National Ambient Air Quality Standards (NAAQS) and California's stricter state standards. The station's siting follows EPA guidelines to ensure representativeness of local air quality. Located in Alameda County, the station serves the Livermore Valley area, which experiences air quality challenges from transportation, industrial activities, and agricultural sources. Data from this station supports public health advisories and regulatory actions. Its long-term operation provides valuable trends for understanding air quality changes in the region.

The Livermore Valley is influenced by emissions from vehicles on Interstate 580 and local industrial sources, as well as agricultural activities in the surrounding areas. Air quality monitoring in this region focuses on ozone and particulate matter, which are common concerns due to the area's Mediterranean climate and topography that can trap pollutants. The station's data helps track compliance with state and federal standards and informs public health protection measures.
