The South Dakota Stormwater Control Ordinance is a set of regulations implemented to manage and control stormwater runoff in the state of South Dakota. This ordinance is designed to protect water quality, reduce pollution, and prevent flooding caused by stormwater runoff. The primary objective of the South Dakota Stormwater Control Ordinance is to minimize the adverse impacts of development and other land use activities on the quality of surface water and the functioning of stormwater infrastructure. It requires developers, construction companies, and property owners to implement the best management practices (BMPs) to capture, treat, and effectively manage stormwater runoff. The South Dakota Department of Environment and Natural Resources (DEER) is responsible for enforcing this ordinance and ensuring compliance. They provide guidelines and technical support to help stakeholders understand and meet the requirements of the ordinance. There are various types of the South Dakota Stormwater Control Ordinance that address different aspects of stormwater management. These may include: 1. Construction Site Stormwater Runoff Control: This component focuses on managing stormwater runoff at construction sites to prevent erosion, sedimentation, and pollutant discharge into nearby water bodies. It requires implementing erosion and sediment control measures, such as silt fences, sediment basins, and stormwater ponds. 2. Post-Construction Stormwater Management: This ordinance targets developed areas after construction is complete. It aims to mitigate the impacts of increased impervious surfaces by implementing stormwater management systems, such as bioretention basins, permeable pavements, or underground detention structures. The goal is to mimic natural hydrological processes and reduce runoff volume and pollutant loads. 3. Illicit Discharge Detection and Elimination: This component focuses on identifying and eliminating unauthorized discharges into storm drains and water bodies. It includes measures to prevent illicit connections from sanitary sewers, industrial facilities, or hazardous waste sites into stormwater systems. 4. Pollution Prevention and Good Housekeeping: This ordinance emphasizes the importance of maintaining and managing stormwater infrastructure, particularly in industrial and commercial areas. It requires regular inspections, maintenance, and implementation of pollution prevention measures to ensure proper functioning of stormwater control facilities. By implementing the South Dakota Stormwater Control Ordinance and its various components, the state aims to protect water resources, maintain healthy ecosystems, and promote sustainable development practices. Compliance with this ordinance is crucial for creating a cleaner and safer environment for current and future generations of South Dakotans.
