Overview
DIRT PIT 17-03-08-0-001-013.00 is a stormwater outfall located in Cullman, Alabama, United States. It operates under the US EPA NPDES MS4 permit framework.
DIRT PIT 17-03-08-0-001-013.00 is a stormwater outfall located at 1802 Warnke Rd NW in Cullman, Cullman County, Alabama, United States. The facility is operational and serves as a discharge point for stormwater runoff from an area associated with mining activities (NAICS codes 212319, 212399, 213115). As a stormwater outfall, it is part of the municipal separate storm sewer system (MS4) and is subject to National Pollutant Discharge Elimination System (NPDES) permitting under the Clean Water Act. The facility operates within the regulatory framework of the US EPA's NPDES MS4 program, which requires permits for stormwater discharges from municipal systems. Phase I and Phase II MS4 permits apply to large and small municipalities, respectively, and include requirements for stormwater management plans, best management practices (BMPs), and monitoring. Given its location in Cullman, a smaller city, it likely falls under Phase II MS4 regulations. Stormwater outfalls like this one play a critical role in managing runoff from urban and industrial areas, helping to prevent flooding and reduce pollutant loads to receiving waters. The environmental significance of this outfall depends on the quality of the discharge and the sensitivity of the receiving water body. Proper operation and maintenance are essential to protect local water resources and comply with regulatory standards.
Environmental context
The facility is located in Cullman, Alabama, within the Tennessee River basin. The region experiences a humid subtropical climate with significant rainfall, leading to substantial stormwater runoff. The outfall discharges into a local water body that may be impaired by pollutants such as sediment, nutrients, and metals from urban and industrial sources. The surrounding area includes mining operations, which can contribute to elevated levels of suspended solids and heavy metals in runoff. Compliance with NPDES permit limits is critical to prevent degradation of water quality and protect aquatic ecosystems.
