The Tennessee Stormwater Control Ordinance (TACO) is a set of regulations established by the Tennessee Department of Environment and Conservation (DEC) to manage stormwater runoff and protect the quality of the state's water resources. The TACO applies to construction activities that disturb more than one acre of land or are part of a larger common plan of development. Under the TACO, builders and developers are required to implement Best Management Practices (BMPs) to control stormwater runoff and prevent erosion and sedimentation. These BMPs include practices such as sediment basins, silt fences, vegetative buffers, and stormwater detention ponds, which are designed to capture and treat stormwater before it is discharged into streams, rivers, and lakes. In addition to erosion and sediment control measures, the TACO also addresses the management of post-construction stormwater runoff. This involves the implementation of structural controls, such as previous pavement, rain gardens, and bioretention cells, which help capture and filter stormwater on-site, reducing the amount of pollution entering water bodies. The TACO also requires the submission of stormwater management plans and reporting of inspections to ensure compliance with the ordinance. These plans outline the site-specific BMPs and strategies for addressing stormwater runoff and pollution. Inspections and reporting help monitor the effectiveness of stormwater control measures and identify any necessary adjustments or improvements. There are different types of Tennessee Stormwater Control Ordinances that may apply based on the jurisdiction or local government agency. These ordinances may have variations in specific requirements, but the overarching goal remains to manage stormwater runoff and protect water quality. It is essential for builders, developers, and landowners to familiarize themselves with the specific TACO regulations applicable to their project location to ensure compliance with the law and to contribute to the preservation and enhancement of Tennessee's water resources.
