UNITED PARCEL SERVICE - LOXLEY Stormwater Outfall, Robertsdale, Alabama

UNITED PARCEL SERVICE - LOXLEY is a stormwater outfall located at 17382 County Road 54 in Robertsdale, Baldwin County, Alabama. This facility manages stormwater runoff from a United Parcel Service logistics center, classified under NAICS 492110 for couriers and express delivery services. As a stormwater outfall, it discharges collected runoff into local waterways, subject to federal and state regulations. The facility operates under the US EPA National Pollutant Discharge Elimination System (NPDES) framework, specifically the Municipal Separate Storm Sewer System (MS4) permits. While Phase I MS4 permits cover large municipalities, Phase II permits apply to smaller entities like this industrial site. The outfall is designed to manage stormwater from impervious surfaces such as parking lots and roofs, reducing flood risk and pollutant transport. In the context of Baldwin County, Alabama, stormwater management is critical due to the region's humid subtropical climate with frequent heavy rainfall. The outfall helps mitigate localized flooding and controls the discharge of sediments, oils, and other pollutants common in logistics operations. This facility contributes to the broader stormwater infrastructure serving the Gulf Coast area, supporting both environmental compliance and community resilience.

This stormwater outfall discharges into the Mobile Bay watershed, a sensitive estuarine ecosystem. The region experiences high annual rainfall (over 60 inches), increasing runoff volumes from impervious surfaces. Urban and industrial catchments like this can introduce pollutants such as heavy metals, hydrocarbons, and sediments into receiving waters. Regulatory oversight under the Clean Water Act aims to protect water quality through NPDES permits, requiring best management practices for stormwater control.
