N.C. Gen. Stat. § 159-95
The general design and plan of any revenue bond project undertaken for water systems or facilities or sewage disposal systems or facilities shall be subject to the approval of the Commission for Public Health or the State Environmental Management Commission to the same extent that such projects would be if they were not financed by revenue bonds, and the provisions of the revenue bond order shall be consistent with any requirements imposed on the project by the Commission for Public Health or the State Environmental Management Commission. No revenue bond project for the acquisition or construction of systems or facilities for the generation, production, or transmission of gas or electric power may be undertaken by the State or a municipality unless the State or municipality, as the case may be, shall first obtain a certificate of convenience and necessity from the North Carolina Utilities Commission.
