MIDDLEPORT is an air monitoring station located at the Middleport STP facility on North Hartland Road in Middleport, New York. Operated under the New York State Department of Environmental Conservation, this station is part of the state's ambient air quality monitoring network, which supports compliance with the US EPA's Air Quality System (AQS) and the National Ambient Air Quality Standards (NAAQS). The station's last reported sample date is September 30, 2025, indicating ongoing data collection. As a regulatory monitoring site, MIDDLEPORT likely measures criteria pollutants such as ozone, particulate matter, nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead, in accordance with EPA monitoring requirements. The station's location in a mixed urban-rural area of Niagara County provides representative data for assessing regional air quality and population exposure. The New York State DEC operates a network of over 100 monitoring stations statewide, with this station contributing to long-term trend analysis and regulatory compliance. The environmental significance of MIDDLEPORT lies in its role in tracking air quality in western New York, an area influenced by industrial activities, transportation corridors, and weather patterns from Lake Ontario. Continuous monitoring helps identify pollution episodes, support health advisories, and inform emission reduction strategies. The station's data also contributes to the EPA's national air quality database, supporting research and policy development.

The MIDDLEPORT air monitoring station operates within the US EPA's regulatory framework, which mandates monitoring of criteria pollutants to protect public health and the environment. The station's siting in Niagara County provides representative data for a region with mixed industrial, agricultural, and residential land uses. Key environmental considerations include parameter coverage (criteria pollutants vs. speciation), siting representativeness relative to population and emission sources, and reporting continuity to ensure robust trend analysis. The station's affiliation with the New York State DEC network ensures adherence to EPA quality assurance protocols.
