This subsection does not prohibit the discharge of waste to a treatment works operated by a public utility or unit of local government in excess of the capacity of the treatment works by any person who holds a valid building permit issued prior to the date on which the public utility or unit of local government receives the notice required by subsection (c) of this section if the Commission finds that the discharge of waste will not result in any significant degradation in the quality of the waters ultimately receiving the discharge as provided in subsection (b) of this section.

The Commission may impose such conditions on permits issued under G.S. 143-215.1 as it deems necessary to implement the provisions of this subsection, including conditions on the size, character, and number of additional dischargers.
