N.C. Gen. Stat. § 162A-75
Prior to the time final plans are made for the location and construction of any sewerage system, the district board shall present preliminary plans for such improvement to the county, municipal or regional planning board for their consideration, if such facility is to be located within the planning jurisdiction of any such county, municipal or regional planning group. The district board shall make every effort to cooperate with the planning agency, if any, in the location and construction of a proposed facility authorized under this Article. Any district board created under the authority of this Article is hereby directed, wherever possible, to coordinate its plans for the construction of sewerage system improvements with the overall plans for the development of the planning area, if such district is located wholly or in part within a county, municipal or regional planning area; provided, however, that the approval of any such county, municipal or regional planning board as to any such plan of the district shall not be required.
