BASELINE MATERIALS Stormwater Outfall, Perdido, Alabama | Industrial Runoff Management

BASELINE MATERIALS is a stormwater outfall facility located in Perdido, Baldwin County, Alabama, United States. The facility is operational and serves an industrial catchment area, with NAICS codes indicating activities in mining and construction material sectors (e.g., crushed stone, sand, gravel, clay, and other nonmetallic minerals). As a stormwater outfall, the facility manages runoff from industrial operations, which is regulated under the US EPA NPDES MS4 program. In Alabama, the Alabama Department of Environmental Management (ADEM) administers the NPDES permit program, including stormwater permits for industrial activities. The facility's discharge is subject to compliance with the Clean Water Act, including effluent limitations and monitoring requirements. The environmental significance of BASELINE MATERIALS lies in its role in controlling stormwater runoff from industrial sites, which can contain sediments, metals, and other pollutants. Proper management helps protect local water bodies, such as those in the Mobile Bay watershed, from degradation. The facility's location in a rural area of Baldwin County underscores the importance of stormwater controls in preserving water quality for downstream ecosystems.

The facility is located in Baldwin County, Alabama, within the Mobile Bay watershed. This region features a humid subtropical climate with high rainfall, increasing the potential for stormwater runoff. Industrial activities such as mining and construction material processing can generate pollutants like sediment, heavy metals, and hydrocarbons. Effective stormwater management is critical to prevent impairment of local streams and rivers, which ultimately drain into Mobile Bay, an ecologically important estuary.
