WESTROCK VALLEY WAREHOUSE Stormwater Outfall, Valley, Alabama | USA

WESTROCK VALLEY WAREHOUSE is a stormwater outfall located at 1479 Valley Industrial Blvd., Valley, Alabama, in Chambers County. The facility is operational and manages stormwater runoff from an industrial catchment, with NAICS codes 322212 (Paperboard Mills) and 333993 (Packaging Machinery Manufacturing). As a stormwater outfall, it discharges collected runoff into local waterways, subject to the US Clean Water Act and NPDES MS4 permit requirements. In the United States, stormwater outfalls like this one are regulated under Phase II of the NPDES MS4 program, which requires permits for small municipal separate storm sewer systems in urbanized areas. The facility's industrial catchment means it may be subject to additional industrial stormwater permitting under EPA's Multi-Sector General Permit (MSGP) or individual permits. The outfall's location in an industrial park suggests a focus on managing runoff from impervious surfaces and potential pollutant loads. The environmental significance of this outfall lies in its role in conveying stormwater from an industrial area to receiving waters. Proper management helps prevent flooding, erosion, and pollution of local streams. The facility contributes to the community's stormwater infrastructure, supporting compliance with local and federal regulations aimed at protecting water quality in Alabama's watersheds.

The facility is located in Valley, Alabama, within the Chattahoochee River watershed. The region experiences a humid subtropical climate with frequent heavy rainfall, increasing the risk of stormwater runoff carrying pollutants from industrial areas. Discharge from this outfall may affect local water bodies, which are subject to Total Maximum Daily Load (TMDL) requirements for pollutants like sediment and nutrients. The industrial catchment, including paperboard and packaging manufacturing, necessitates robust stormwater management to prevent contamination of receiving waters.
