Amends GS 130A-343 by amending one of the ways in which a manufacturer of a wastewater system for on‑site subsurface use may apply and be considered for innovative system status to now provide that if the wastewater system has not been evaluated or approved as a provisional system, but has been approved (was, evaluated) under protocol established by a nationally recognized certification body (was, by a nationally recognized certification body for at least two consecutive years) has been found to perform acceptably based on the criteria of the protocol, and is designed and will be installed in a manner consistent with the system evaluated and approved by the nationally recognized certification body, the manufacturer may apply to have the system approved as an innovative wastewater system. Adds the requirement that the Department of Health and Human Services approve the application and issue an innovative wastewater system approval in accordance with rules adopted by the Commission for Public Health upon verifying (1) the nationally recognized certification body's approval and (2) that the design and installation plans are consistent with that approval.
