Overview
Diamond Gasoline Stations is an operational stormwater outfall in Atmore, Alabama, managing runoff from a car wash facility under the US EPA NPDES MS4 program.
Diamond Gasoline Stations is a stormwater outfall located at 1421 S Main St in Atmore, Escambia County, Alabama, United States. The facility is operational and serves as a point of discharge for stormwater runoff from a car wash operation (NAICS 811192). As a stormwater outfall, it is part of the broader network of municipal separate storm sewer systems (MS4) regulated under the Clean Water Act. In Alabama, stormwater discharges are regulated through the National Pollutant Discharge Elimination System (NPDES) program, administered by the Alabama Department of Environmental Management (ADEM). Facilities like Diamond Gasoline Stations must comply with general permits for stormwater discharges associated with industrial activity. The outfall likely conveys runoff from impervious surfaces such as parking lots and building roofs, which can carry pollutants like oil, grease, and sediment. The environmental significance of this outfall lies in its potential impact on local water bodies. Atmore is located in the Gulf Coast region, where stormwater runoff can affect streams and rivers that drain into the Mobile Bay estuary. Proper management of stormwater quality is essential to protect aquatic habitats and comply with water quality standards. The facility's location in a small urban area means it contributes to the cumulative stormwater load in the region.
Environmental context
Atmore, Alabama, lies in the Gulf Coastal Plain, characterized by sandy soils and a humid subtropical climate with frequent heavy rainfall. Stormwater runoff from urban and industrial areas can carry pollutants such as hydrocarbons, heavy metals, and nutrients into local waterways. The Escambia County area drains into the Conecuh River and eventually the Mobile Bay estuary, a productive ecosystem sensitive to nutrient loading and sedimentation. Effective stormwater management is critical to prevent degradation of these water bodies and to comply with the Clean Water Act's total maximum daily load (TMDL) requirements.
