Overview
Henry Marine Service, Inc. operates a stormwater outfall in Mobile, Alabama, managing runoff from a ship building and repairing facility under US EPA NPDES MS4 regulations.
Henry Marine Service, Inc. manages a stormwater outfall located at 887 Cochrane Causeway in Mobile, Alabama. This facility handles stormwater runoff from an industrial site classified under NAICS 336611 (Ship Building and Repairing), operating within the Mobile urban area. As a stormwater outfall, it discharges collected runoff into local waterways, subject to federal and state permitting requirements. The facility operates under the US EPA National Pollutant Discharge Elimination System (NPDES) framework, which governs stormwater discharges from industrial activities. In Alabama, the Alabama Department of Environmental Management (ADEM) administers the NPDES program, requiring facilities like Henry Marine Service to obtain Multi-Sector General Permits (MSGP) for stormwater discharges. The facility's industrial classification suggests potential exposure to pollutants typical of shipbuilding operations, including metals, oils, and solvents. Located in Mobile County, the outfall discharges into the Mobile River system, which flows into Mobile Bay. This region supports diverse aquatic habitats and is subject to water quality standards under the Clean Water Act. Proper management of stormwater runoff is critical to minimize impacts on downstream water bodies, particularly given the industrial nature of the catchment area.
Environmental context
The facility discharges stormwater into the Mobile River system, which drains into Mobile Bay, an ecologically significant estuary. The catchment area is industrial, with shipbuilding activities contributing potential pollutants such as heavy metals, hydrocarbons, and sediments. Regulatory oversight under the Clean Water Act and ADEM permits aims to control these discharges to protect water quality and aquatic life.
