The Indiana Erosion and Sediment Control Ordinance is a regulatory framework established by the state of Indiana to minimize erosion and sedimentation caused by construction activities. This ordinance aims to protect the quality of Indiana's water resources by implementing the best management practices (BMPs) that prevent soil erosion and sediment runoff into nearby water bodies. By implementing the Indiana Erosion and Sediment Control Ordinance, construction and development projects in Indiana must adhere to specific guidelines and practices to control erosion and sedimentation. These guidelines include the installation of erosion control measures, such as sediment basins, silt fences, or straw bales, to effectively contain sediment during construction activities. Site stabilization measures, such as the use of grass or cover crops, are also essential to prevent soil erosion once construction is complete. The Indiana Department of Environmental Management (IDEM) is responsible for overseeing adherence to the Erosion and Sediment Control Ordinance. They provide guidance and resources to individuals, developers, and contractors to ensure compliance and the proper implementation of erosion control measures. IDEM also conducts inspections and may issue enforcement actions or penalties for non-compliance. There are different types of ordinances related to erosion and sediment control in Indiana, including: 1. Construction General Permit (CAP): This permit applies to projects that disturb one acre or more of land. It includes specific requirements and best management practices for erosion and sediment control during construction. 2. Municipal Separate Storm Sewer System (MS4) Permit: This ordinance applies to municipalities that have stormwater discharge systems. MS4 permits address stormwater runoff issues, including erosion and sediment control, within urban areas. 3. Local Level Ordinances: Some local jurisdictions in Indiana may have their own erosion and sediment control ordinances that align with or enhance the state requirements. These local ordinances may have additional specifications or site considerations tailored to their specific region. Adhering to the Indiana Erosion and Sediment Control Ordinance is crucial to maintaining the health of Indiana's water bodies and ecosystems. It promotes environmentally responsible construction practices that minimize the negative impacts of erosion and sedimentation, ensuring sustainable development in the state.
