Overview
HOLLAND 345 is a stormwater outfall located in Birmingham, Alabama, United States. It operates under the US EPA NPDES MS4 permit framework for managing urban runoff.
HOLLAND 345 is a stormwater outfall located at 480 Republic Circle in Birmingham, Jefferson County, Alabama, United States. As a stormwater outfall, it serves as a discharge point for stormwater runoff from the surrounding urban catchment, which includes industrial and residential areas. The facility is operational and falls under the regulatory oversight of the US EPA's National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) program, which governs stormwater discharges in urbanized areas. In Alabama, stormwater management is regulated by the Alabama Department of Environmental Management (ADEM) under the NPDES MS4 permit program. Phase II MS4 permits apply to smaller municipalities like Birmingham, requiring stormwater management plans to reduce pollutant discharges to the maximum extent practicable. The outfall likely conveys runoff from a mixed urban and industrial catchment, which may include pollutants such as sediment, heavy metals, and hydrocarbons. Typical stormwater outfalls in this region are designed to handle peak flows from rainfall events and may include basic treatment features like detention basins or oil-water separators. The environmental significance of HOLLAND 345 lies in its role in managing stormwater quality and quantity in the Birmingham area. Discharges from this outfall may ultimately reach local water bodies such as Village Creek or the Black Warrior River, which are subject to water quality standards under the Clean Water Act. Proper operation and maintenance of the outfall are essential to prevent flooding and minimize pollutant loads to receiving waters, supporting the ecological health of the region's aquatic ecosystems.
Environmental context
The Birmingham area experiences a humid subtropical climate with frequent thunderstorms and heavy rainfall, leading to significant stormwater runoff. Urban and industrial land uses in the catchment contribute pollutants such as sediment, nutrients, and metals. Discharges from HOLLAND 345 may affect local streams and rivers, which are subject to Total Maximum Daily Load (TMDL) requirements for impaired water bodies. The facility operates under NPDES MS4 permit conditions aimed at controlling runoff through best management practices.
