Overview
OPP FACILITY is a stormwater outfall in Opp, Alabama, United States. It operates under the US EPA NPDES MS4 permit framework for stormwater discharge management.
OPP FACILITY is a stormwater outfall located at 601A Highway 52 East in Opp, Covington County, Alabama, United States. As a stormwater outfall, it serves as a discharge point for stormwater runoff from the surrounding urban and industrial catchment areas. The facility is operational and falls under the regulatory oversight of the US Environmental Protection Agency's National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) program. In the United States, stormwater outfalls like OPP FACILITY are subject to Phase II MS4 permit requirements for small municipalities, which mandate the development of stormwater management programs to reduce pollutant discharges. The facility's location in Alabama places it within a region where stormwater management is critical due to the state's frequent rainfall events and the potential for runoff to impact local water bodies. Typical stormwater outfalls in this area may incorporate best management practices such as detention basins, vegetated swales, or filtration systems to control flow and improve water quality. The environmental significance of OPP FACILITY lies in its role in conveying stormwater from the Opp urban area to receiving waters. Proper operation and maintenance of the outfall help mitigate flooding risks and reduce the transport of pollutants like sediment, nutrients, and heavy metals into downstream ecosystems. The facility contributes to the community's resilience against storm events and supports compliance with Clean Water Act objectives for protecting water quality.
Environmental context
The OPP FACILITY stormwater outfall discharges into local waterways in Covington County, Alabama, a region characterized by a humid subtropical climate with high annual rainfall. Stormwater runoff from urban areas in Opp can carry pollutants such as sediment, oil, grease, and nutrients, potentially impacting the ecological health of receiving streams. The facility operates under the US EPA NPDES MS4 permit framework, which requires implementation of stormwater management practices to minimize these impacts and protect water quality.
Frequently asked questions
OPP FACILITY is located at 601A Highway 52 East in Opp, Covington County, Alabama, United States.
OPP FACILITY is a stormwater outfall that discharges stormwater runoff from the Opp urban area into local waterways, helping manage flood risks and convey runoff.
OPP FACILITY operates under the US EPA National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permit program, which requires stormwater management to reduce pollutant discharges.
In Alabama, stormwater management is governed by the Alabama Department of Environmental Management (ADEM) under the NPDES MS4 program. Permittees must develop stormwater management plans that include public education, illicit discharge detection, construction site runoff control, and pollution prevention.
Common pollutants in stormwater runoff include sediment, nutrients (nitrogen and phosphorus), heavy metals, oil and grease, pesticides, and pathogens. These can degrade water quality and harm aquatic ecosystems.
