JET-PEP #23 Stormwater Outfall, Decatur, Alabama | United States

JET-PEP #23 is a stormwater outfall located at 2506 Highway 20 West in Decatur, Alabama, within Morgan County. This facility manages stormwater runoff from an area associated with NAICS codes 447110 and 457110, which correspond to gasoline stations and related retail operations. As a stormwater outfall, it discharges collected runoff into local waterways, playing a key role in managing urban and industrial stormwater in the region. The facility operates under the regulatory framework of the US Clean Water Act, specifically through the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits. Decatur, as part of the Tennessee Valley, is subject to Phase II MS4 requirements for small municipalities, which mandate stormwater management programs to reduce pollutant discharges. The outfall likely serves an industrial or commercial catchment, given the NAICS codes, and may be subject to additional industrial stormwater permitting. Environmental significance of JET-PEP #23 lies in its role in controlling runoff from impervious surfaces and potential pollutant sources. The facility helps mitigate flooding and water quality impacts in the Tennessee River watershed, which receives discharges from the Decatur area. Proper operation of this outfall supports compliance with local water quality standards and protects downstream aquatic habitats.

The Decatur area lies within the Tennessee River basin, a region with significant industrial and agricultural activity. Stormwater runoff from commercial and industrial sites can carry pollutants such as hydrocarbons, heavy metals, and sediments. The facility's discharge may affect water quality in receiving streams, particularly during heavy rainfall events. Regulatory oversight under the NPDES MS4 program aims to control these impacts through best management practices and monitoring.
