Overview
D & D Engines of Huntsville, Inc. is a stormwater outfall located in Hazel Green, Alabama, United States. It operates under the US EPA NPDES MS4 permit framework for stormwater discharges.
D & D Engines of Huntsville, Inc. is a stormwater outfall facility situated at 14044 A Highway 231 North in Hazel Green, Madison County, Alabama. As a stormwater outfall, it manages runoff from an industrial catchment, likely associated with the motor vehicle parts and supplies sector (NAICS 423140). The facility is operational and falls under the regulatory oversight of the US EPA's National Pollutant Discharge Elimination System (NPDES) program, specifically the MS4 permit requirements for industrial stormwater discharges. In Alabama, stormwater outfalls are regulated under the Alabama Department of Environmental Management (ADEM) which implements the NPDES program. Facilities like this one must obtain coverage under a Multi-Sector General Permit (MSGP) or an individual permit, depending on the nature of their operations and discharge characteristics. The facility's location in a suburban area near Huntsville suggests potential impacts on local water bodies, which are subject to monitoring and best management practices to control pollutants. The environmental significance of this outfall lies in its contribution to the overall stormwater management in the Tennessee Valley region. Proper operation and maintenance of stormwater controls are essential to protect receiving waters from pollutants such as sediment, oil, grease, and heavy metals commonly associated with industrial activities. Compliance with permit conditions helps safeguard water quality in downstream ecosystems.
Environmental context
The facility is located in the Tennessee Valley region of northern Alabama, an area characterized by a humid subtropical climate with significant rainfall, leading to substantial stormwater runoff. The outfall likely discharges to a tributary of the Tennessee River, which is a major water body supporting diverse aquatic life and recreational uses. Industrial stormwater runoff from facilities like this can introduce pollutants such as metals, hydrocarbons, and suspended solids, posing risks to water quality and aquatic habitats. Regulatory oversight under the NPDES program aims to mitigate these impacts through pollution prevention plans and monitoring.
