McMinnville - McMinville High School (MHS) Air Monitoring Station, McMinnville, Oregon

McMinnville - McMinville High School (MHS) is an air monitoring station located at 615 NE 15th Street in McMinnville, Oregon, within Yamhill County. Operated by the Oregon Department of Environmental Quality, this station is part of the broader US EPA Air Quality System (AQS) network, which monitors ambient air quality across the United States. As a fixed-site monitor, it provides localized data on pollutant concentrations, supporting regulatory compliance and public health assessments. The station operates under the framework of the Clean Air Act and EPA monitoring regulations, which mandate criteria pollutant measurements such as ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide. While specific parameters measured at this site are not detailed, typical high school stations in Oregon focus on ozone and PM2.5 due to regional concerns. The Oregon DEQ ensures siting representativeness and data quality through standard operating procedures and periodic audits. This monitoring station serves the McMinnville community by providing air quality data that informs local health advisories and regulatory decisions. Its location at a high school allows for exposure assessment in a sensitive population area. The data contributes to regional air quality trends and supports the EPA's mission to reduce air pollution and protect human health and the environment.

McMinnville is located in the Willamette Valley, a region known for agricultural activities and occasional wildfire smoke events that can elevate particulate matter levels. The station's placement at a high school provides representative sampling of urban background air quality, capturing emissions from local traffic and industrial sources. Monitoring criteria pollutants like ozone and PM2.5 is critical for assessing compliance with National Ambient Air Quality Standards (NAAQS) and protecting vulnerable populations, including schoolchildren.
