SETRPC 43 Jefferson Co Airport Air Monitoring Station, Port Arthur, Texas

SETRPC 43 Jefferson Co Airport is an air monitoring station located at Jefferson County Airport in Port Arthur, Texas, United States. It is part of the state's ambient air monitoring network, overseen by the Texas Commission on Environmental Quality (TCEQ). The station contributes to the U.S. EPA's Air Quality System (AQS) network, which tracks criteria pollutants and other atmospheric parameters. The station operates under the regulatory framework of the U.S. Clean Air Act, which mandates monitoring of pollutants such as ozone, particulate matter, carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead. TCEQ maintains a network of stations across Texas to ensure compliance with National Ambient Air Quality Standards (NAAQS). The station's location at an airport allows for representative sampling of urban and transportation-related emissions. Port Arthur is an industrial city with significant petrochemical and refining activities, making air quality monitoring critical for public health and environmental management. Data from this station supports local air quality assessments, regulatory compliance, and community awareness. The station's operational status and recent sampling (as of June 2025) indicate ongoing contribution to regional air quality surveillance.

The station's siting at an airport provides representative monitoring of emissions from aviation and surrounding industrial sources. Parameter coverage typically includes criteria pollutants and meteorological parameters, though specific instrumentation may vary. The station supports the TCEQ's goal of maintaining a robust monitoring network to assess air quality trends and protect public health in the Beaumont-Port Arthur industrial corridor.
