Overview
Robertson Ready Mix is an operational stormwater outfall in Winfield, Alabama, USA. It manages runoff from an industrial concrete facility under local stormwater regulations.
Robertson Ready Mix is a stormwater outfall located at 480 Kirkwood Street in Winfield, Marion County, Alabama, United States. This facility manages stormwater discharge from a ready-mix concrete operation, a common industrial source of runoff containing sediment and alkaline materials. As a stormwater outfall in the United States, this facility operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) program. Industrial stormwater discharges are typically regulated through Multi-Sector General Permits (MSGP) or individual permits, requiring implementation of best management practices (BMPs) to control pollutants. The facility's location in a small urban area in Alabama suggests it may be subject to Phase II MS4 requirements if the municipality has a regulated storm sewer system. The environmental significance of this outfall lies in its potential to affect local water quality in Marion County. Stormwater from industrial sites can carry suspended solids, heavy metals, and other pollutants into nearby streams and rivers. Proper management of this outfall helps protect downstream water bodies from sedimentation and contamination, supporting the ecological health of the region.
Environmental context
Winfield, Alabama, is located in the Black Warrior River watershed, which drains into the Mobile Bay estuary. The region experiences a humid subtropical climate with frequent thunderstorms, leading to high stormwater runoff volumes. Industrial outfalls like Robertson Ready Mix must manage runoff to prevent erosion and pollutant transport, particularly sediment from concrete operations, which can impair aquatic habitats and increase turbidity in receiving waters.
Frequently asked questions
Robertson Ready Mix is located at 480 Kirkwood Street in Winfield, Marion County, Alabama, United States.
Robertson Ready Mix is a stormwater outfall that manages runoff from a ready-mix concrete facility, discharging treated or managed stormwater into local waterways under NPDES permit requirements.
Stormwater outfalls in Alabama are regulated under the Clean Water Act through the NPDES program, administered by the Alabama Department of Environmental Management (ADEM). Industrial facilities must obtain coverage under a Multi-Sector General Permit (MSGP) and implement stormwater pollution prevention plans (SWPPP).
Stormwater from concrete plants can contain high pH levels, suspended solids, and heavy metals. Proper management through sedimentation basins, pH adjustment, and erosion controls is essential to prevent harm to aquatic life and comply with water quality standards.
The NPDES program requires industrial facilities to obtain permits for stormwater discharges, implement best management practices (BMPs), monitor effluent, and submit reports to ensure compliance with water quality standards and protect receiving waters.
