The Oklahoma Erosion and Sediment Control Ordinance is a set of regulations implemented by the state of Oklahoma to address the issues of erosion and sediment control in construction sites and land development projects. This ordinance aims to prevent soil erosion, sedimentation, and the pollution of water bodies, ensuring the protection of natural resources and maintaining the overall environmental quality. One type of Oklahoma Erosion and Sediment Control Ordinance is the General Construction Permit for Stormwater Discharges. This permit applies to construction activities that disturb one acre or more of land or are part of a larger common plan of development that disturbs one acre or more. It requires project developers to implement Best Management Practices (BMPs) to prevent erosion and control sedimentation during construction. Another type of Oklahoma Erosion and Sediment Control Ordinance is the Municipal Separate Storm Sewer System (MS4) Permit. This permit applies to municipalities or other entities that operate a separate storm sewer system collecting and discharging stormwater. It requires these entities to establish an erosion and sediment control program that includes public education, construction site inspections, and the enforcement of erosion and sediment control measures on construction sites within their jurisdiction. The Oklahoma Erosion and Sediment Control Ordinance mandate the implementation of various erosion and sediment control measures, such as the use of silt fences, sediment basins, erosion control blankets, and sediment traps. It also emphasizes the importance of properly managing stormwater runoff through effective drainage design and installation of erosion control devices. It should be noted that compliance with the Oklahoma Erosion and Sediment Control Ordinance is essential for developers and contractors to obtain necessary permits for their construction projects. Failure to adhere to these regulations may result in penalties, citations, or even the halt of construction activities until the necessary erosion and sediment control measures are implemented to ensure compliance. In summary, the Oklahoma Erosion and Sediment Control Ordinance encompasses regulations designed to prevent soil erosion, sedimentation, and water pollution during construction activities. The General Construction Permit for Stormwater Discharges and the Municipal Separate Storm Sewer System (MS4) Permit are two components of this ordinance, each addressing different aspects of erosion and sediment control. Proper compliance and implementation of erosion control measures are crucial for construction projects in Oklahoma to protect natural resources and maintain environmental quality.
