PRYOR FIELD AIRPORT AUTHORITY Stormwater Outfall, Athens, Alabama

PRYOR FIELD AIRPORT AUTHORITY operates a stormwater outfall located at 7046 US HIGHWAY 31 in Athens, Limestone County, Alabama. As an airport-related facility, it manages stormwater runoff from impervious surfaces such as runways, taxiways, and parking lots. The outfall discharges into local waterways, and its operations are subject to the National Pollutant Discharge Elimination System (NPDES) permitting framework under the Clean Water Act. Stormwater outfalls at airports like this one typically require permits under the NPDES program, often as part of a larger Municipal Separate Storm Sewer System (MS4) or industrial stormwater permit. The facility's NAICS code 488119 (Other Airport Operations) indicates it falls under industrial stormwater regulations. Management practices may include detention basins, oil-water separators, and regular monitoring to control pollutants such as sediment, deicing chemicals, and fuel residues. The environmental significance of this outfall lies in its potential impact on receiving waters in the Tennessee River basin. Proper stormwater management at airports is critical to prevent contamination from aviation-related activities. The facility's compliance with NPDES permit conditions helps protect local water quality and aquatic habitats.

The stormwater outfall at PRYOR FIELD AIRPORT AUTHORITY discharges into local waterways that are part of the Tennessee River watershed. This region experiences a humid subtropical climate with significant rainfall, increasing the potential for runoff-related pollution.
