Erosion and sediment control practices must be in full compliance with all specifications governing the proper design, installation and operation and maintenance of such Best Management Practices in order to protect surface waters standards: a. The erosion and sediment control measures for the project must be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Sediment and Erosion Control Planning and Design Manual. b. The design, installation, operation, and maintenance of the sediment and erosion control measures must be such that they equal, or exceed, the requirements specified in the most recent version of the North Carolina Sediment and Erosion Control Manual.

No changes to the structural stormwater practices shall be made without written authorization from the Division of Water Quality. Stormwater easements shall be recorded for a distance of at least 10 feet on each side of all stormwater conveyances on all lots containing these structures including future access for maintenance.
