SHERMAN INDUSTRIES - MONTEVALLO PLANT Stormwater Outfall, Montevallo, Alabama

SHERMAN INDUSTRIES - MONTEVALLO PLANT is a stormwater outfall located at 6824 Highway 25 in Montevallo, Shelby County, Alabama. This facility manages stormwater runoff from an industrial site classified under NAICS 327320 (ready-mix concrete manufacturing). The plant is operational and falls under the regulatory oversight of the US EPA's National Pollutant Discharge Elimination System (NPDES) program. As a stormwater outfall, the facility is subject to NPDES permitting requirements for industrial stormwater discharges. The Clean Water Act mandates that such outfalls implement best management practices (BMPs) to control pollutants. In Alabama, the Alabama Department of Environmental Management (ADEM) administers the NPDES program, ensuring compliance with water quality standards. The plant's environmental significance lies in its role in managing stormwater from concrete manufacturing, which can involve pollutants like sediment and pH imbalances. Proper operation helps protect local water bodies, including nearby streams and the Cahaba River watershed. The facility contributes to regional stormwater management in Shelby County, an area experiencing urban growth.

The facility is located in the Cahaba River watershed, a biologically diverse region in Alabama. Stormwater runoff from industrial sites like this can carry sediment, heavy metals, and other pollutants if not properly managed. The area's clay soils and rolling topography can increase runoff volumes during heavy rains, making effective stormwater control critical for protecting downstream water quality.
