Pendleton - STATE OFFICE BLDG Air Monitoring Station, Oregon | USA

Pendleton - STATE OFFICE BLDG is an air monitoring station located at the State Office Building in Pendleton, Oregon, within Umatilla 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 criteria pollutants and other atmospheric parameters across the United States. The station operates under the regulatory framework of the Clean Air Act and EPA ambient air quality standards. Typical air monitoring stations in Oregon measure pollutants such as PM2.5, PM10, ozone, nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead. The station's siting in an urban area provides representative data for population exposure assessment. This monitoring station supports public health and environmental management by providing data used for air quality index reporting, regulatory compliance, and trend analysis. Its location in Pendleton, a city in eastern Oregon, helps characterize air quality in a region influenced by agriculture, transportation, and occasional wildfire smoke.

Pendleton is located in the Columbia Plateau ecoregion, characterized by semi-arid climate and agricultural land use. Air quality in the area can be affected by agricultural burning, dust from farming activities, and seasonal wildfires. The monitoring station's placement in an urban setting helps capture population-relevant exposures. Parameter coverage typically includes criteria pollutants, with potential for additional speciation depending on network priorities.
