PHI INC. - THEODORE BASE Stormwater Outfall, Theodore, Alabama

PHI INC. - THEODORE BASE is a stormwater outfall located at 6000A Deakle Road in Theodore, Mobile County, Alabama, United States. The facility is operational and serves as a point of discharge for stormwater runoff from the surrounding area, which includes industrial and urban land uses typical of the Gulf Coast region. The facility operates under the regulatory framework of the US Clean Water Act, specifically the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits. As a stormwater outfall, it is part of a network designed to manage runoff and prevent flooding while protecting water quality in receiving waters. The NAICS codes associated with the facility (481211 and 481212) indicate connections to nonscheduled air transportation and scheduled air transportation, suggesting the outfall may serve an airport or aviation-related industrial area. The environmental significance of this outfall lies in its role in managing stormwater runoff from an industrial catchment in Mobile County, which drains into the Mobile Bay estuary. Proper stormwater management is critical in this region to reduce pollutant loads and protect aquatic habitats. The facility's compliance with NPDES permits ensures that discharges meet water quality standards, supporting the ecological health of local waterways.

The Theodore area is part of the Mobile Bay watershed, a biologically productive estuary that supports diverse marine life and commercial fisheries. Stormwater runoff from industrial and urban areas can carry pollutants such as sediments, heavy metals, and hydrocarbons, posing risks to water quality. Regulatory oversight through NPDES MS4 permits aims to mitigate these impacts through best management practices and monitoring.
