Portland - Parkrose Deliverance Tabernacle (PDT) Air Monitoring Station, Portland, Oregon

Portland - Parkrose Deliverance Tabernacle (PDT) is an air monitoring station located at 5740 NE Portland Hwy in Portland, Multnomah County, Oregon. It is part of the United States' extensive air quality monitoring network, which operates under the US EPA Air Quality System (AQS) framework. The station is operated by the Oregon Department of Environmental Quality and is currently operational. The station monitors ambient air quality in the Portland metropolitan area, a region with diverse emission sources including transportation, industrial activities, and residential heating. Under the Clean Air Act, such stations typically measure criteria pollutants such as ozone, particulate matter (PM2.5 and PM10), nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead. The data collected supports compliance with National Ambient Air Quality Standards (NAAQS) and informs public health advisories. As part of the Oregon DEQ's monitoring network, this station provides critical data for assessing air quality trends and ensuring regulatory compliance. The Portland area has historically faced challenges with ozone and particulate matter, making continuous monitoring essential for protecting public health and the environment. The station's location in a residential and commercial area helps characterize population exposure to air pollutants.

The Portland metropolitan area experiences a mix of air pollution sources, including vehicle emissions, industrial facilities, and wood smoke from residential heating. The region's topography and weather patterns can trap pollutants, leading to elevated concentrations during inversions. Monitoring stations like this one are sited to capture representative ambient conditions and support the EPA's AQS network. The data helps track compliance with NAAQS and informs local air quality management strategies.
