Martin Pit 31.07 -87.35 Stormwater Outfall, Atmore, Alabama | US EPA NPDES MS4

Martin Pit 31.07 -87.35 is a stormwater outfall located off Racetrack Rd in Atmore, Alabama, within Escambia County. As a stormwater outfall, it functions as a discharge point for collected stormwater runoff, typically from urban or industrial catchments. 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, which governs stormwater discharges in the United States. The facility's NAICS codes (212321 and 212399) indicate an association with construction sand and gravel mining, as well as other nonmetallic mineral mining and quarrying. This suggests the outfall may serve an industrial catchment related to mining activities, which can influence the characteristics of stormwater runoff, including sediment load and potential contaminants. Stormwater outfalls in such contexts are typically designed to manage runoff volume and quality, often incorporating best management practices (BMPs) to mitigate environmental impacts. In the broader context of Alabama's stormwater management, this outfall contributes to local flood control and water quality protection. Discharges from industrial catchments are subject to additional NPDES permitting requirements under the Clean Water Act, including stormwater pollution prevention plans (SWPPPs). The facility's location in Escambia County, near the Conecuh River watershed, underscores its role in managing runoff that could affect downstream water bodies.

The outfall is located in Escambia County, Alabama, within the Gulf Coastal Plain region. The area's climate features heavy rainfall events, particularly during hurricane season, which can generate significant stormwater runoff. The outfall likely discharges into a local water body that may be part of the Conecuh River watershed, which ultimately flows into the Gulf of Mexico. Industrial catchments, such as those associated with mining, can contribute sediment and other pollutants to stormwater, necessitating effective management to protect water quality and aquatic habitats.
