FILLIN STATION Stormwater Outfall in Wagarville, Alabama | United States

FILLIN STATION is a stormwater outfall located at 21621 HWY 43 in Wagarville, Washington County, Alabama, United States. As a stormwater outfall, it serves as a discharge point for stormwater runoff from the surrounding area, likely including the nearby highway and commercial facilities such as gas stations (NAICS codes 447110 and 457110). The facility is operational and falls under the regulatory oversight of the US EPA's National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) program. In the United States, stormwater outfalls are regulated under Phase I and Phase II MS4 permits, which require operators to develop stormwater management programs to reduce pollutant discharges to the maximum extent practicable. The facility's location in a small town suggests it may be part of a small MS4, subject to Phase II requirements. The NAICS codes indicate potential industrial activity, which may require additional stormwater pollution prevention plans under the Clean Water Act. The environmental significance of FILLIN STATION lies in its role in managing stormwater runoff from a mixed urban and industrial catchment. Discharges from such outfalls can impact local water quality, particularly if they enter impaired water bodies. The facility's compliance with permit conditions is critical to protecting downstream ecosystems and meeting water quality standards in Alabama.

The stormwater outfall at FILLIN STATION discharges runoff from an area that includes highway infrastructure and commercial facilities, which can contribute pollutants such as sediment, oil, grease, and heavy metals. The local environmental context in Washington County, Alabama, includes sensitive water bodies that may be subject to Total Maximum Daily Load (TMDL) requirements. Effective stormwater management is essential to prevent degradation of these waters and to comply with the Clean Water Act.
