SCHILLINGER ROAD PIT Stormwater Outfall, Semmes, Alabama

SCHILLINGER ROAD PIT is a stormwater outfall located at approximately 2534 Schillinger Road in Semmes, Alabama, within Mobile County. This facility is part of the stormwater management infrastructure for the region, handling runoff from urban and industrial catchments. As a stormwater outfall, it discharges collected stormwater into local waterways, playing a key role in flood control and water quality management. The facility operates under the regulatory framework of the US Clean Water Act, specifically the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits. Given its location in Alabama, it likely falls under Phase II MS4 requirements for smaller municipalities. The NAICS code 212399 indicates the site may be associated with nonmetallic mineral mining, suggesting the pit could be a former quarry repurposed for stormwater detention. SCHILLINGER ROAD PIT contributes to local stormwater management by reducing peak flows and filtering pollutants before discharge. Its operational status ensures ongoing compliance with environmental regulations, protecting downstream water bodies in the Mobile Bay watershed. The facility's location in a growing suburban area underscores its importance in managing increased runoff from development.

The facility discharges into the Mobile Bay watershed, which is ecologically significant for its estuarine habitats and biodiversity. Urban runoff from Semmes and surrounding areas can carry pollutants such as sediment, nutrients, and heavy metals. The outfall's performance is critical to maintaining water quality in receiving streams, especially given the region's high rainfall and potential for flooding.
