What size project must sediment basins be built over?

Sediment basins are designed to control sediment runoff from construction sites, helping to protect water quality and the environment. In North Carolina, the regulation stipulates that these basins must be implemented for projects that disturb 1 acre or greater of land. This threshold is important because even seemingly small disturbances can contribute significantly to sedimentation in nearby water bodies, particularly during storms. By establishing sediment basins for projects meeting or exceeding this size, the state aims to minimize erosion and the transport of pollutants into waterways, promoting responsible land management practices. Maintaining strict guidelines for projects of this size is crucial for effective stormwater management and environmental protection in North Carolina.
