HEIDELBERG MATERIALS SOUTHEAST AGG LLC - LEEDS PLANT is a stormwater outfall located at 1704 Parkway Drive SE, Leeds, Alabama, in Jefferson County. The facility is operational and serves as a point of discharge for stormwater runoff from industrial aggregate operations, including NAICS codes 327320 (Ready-Mix Concrete Manufacturing) and 327390 (Other Concrete Product Manufacturing). As a stormwater outfall, it is part of the broader stormwater management infrastructure for the site. The facility operates under the regulatory framework of the US Clean Water Act, specifically the National Pollutant Discharge Elimination System (NPDES) program. Stormwater discharges from industrial activities are typically regulated under NPDES Multi-Sector General Permits (MSGP) or individual permits. The site's industrial classification suggests potential pollutants include sediment, concrete washout, and other construction-related materials. Best management practices (BMPs) such as sediment basins, silt fences, and vegetative buffers are commonly employed to control runoff quality. The environmental significance of this outfall lies in its role in managing stormwater runoff from an industrial aggregate facility. Proper stormwater management helps prevent erosion, sedimentation, and contamination of local waterways. The outfall likely discharges to a nearby waterbody, potentially affecting water quality in the region. Compliance with NPDES permit conditions is critical to minimize environmental impact and protect aquatic ecosystems.
