 130A-343. Approval of on-site subsurface wastewater systems.(a) Definitions. - As used in this section:(1) "Accepted wastewater dispersal system" means any subsurface wastewater dispersal system, other than a conventional wastewater system, that: (i) has been previously approved as an Innovative wastewater dispersal system or is a wastewater dispersal system specifically identified in a rule adopted by the Commission; (ii) has been in general use in this State as a wastewater dispersal system for more than five years; and (iii) has been approved by the Commission for general use or use in one or more specific applications. An Accepted wastewater dispersal system may be approved for use in applications for which a conventional wastewater system is unsuitable. The Commission may impose design, operation, maintenance, monitoring, and management requirements on the use of an Accepted wastewater dispersal system that it determines to be appropriate.(2) Recodified as subdivision (a)(7).(3) "Conventional wastewater system", "conventional sewage system", or "conventional septic tank system" means a subsurface wastewater system that consists of a traditional septic or settling tank and a gravity-fed subsurface dispersal field that uses washed natural stone or gravel of approved size and grade and piping to distribute effluent to soil in one or more nitrification trenches and that does not include any other appurtenance.(4) Repealed by Session Laws 2015-286, s. 4.15(a), effective October 22, 2015.(5) "Innovative wastewater system" means any wastewater system, other than a conventional wastewater system or a provisional wastewater system, or any technology, device, or component of a wastewater system that: (i) has been demonstrated to perform in a manner equal or superior to a conventional wastewater system; (ii) is constructed of materials whose physical and chemical properties provide the strength, durability, and chemical resistance to allow the system to withstand loads and conditions as required by rules adopted by the Commission; and (iii) has been approved by the Department for general use or for one or more specific applications. An innovative wastewater system may be approved for use in applications for which a conventional wastewater system is unsuitable. The Department may impose any design, operation, maintenance, monitoring, and management requirements on the use of an innovative wastewater system that it determines to be appropriate. A wastewater system approved by a nationally recognized certification body and in compliance with the ongoing verification program of such body may submit a sampling protocol for innovative system approval that reduces the data sets required for such approval by fifty percent (50%). Such an application shall include all of the data associated with the nationally recognized certification body's verification of the system's performance.(6) "Nationally recognized certification body" means a third-party certification body for wastewater systems or system components that is accredited by an entity widely recognized in the United States such as the American National Standards Institute, the Standards Council of Canada, or the International Accreditation Service, Inc.(6a) "Prefabricated permeable block panel system" is a series of units for onsite wastewater dispersal manufactured of cementitious materials of coarse and fine lightweight expanded shale aggregate along with Portland cement, connected together by plastic pipe. The unit shall be of rigid design, constructed and installed to withstand load requirements without collapse, compression, or deflection.(7) "Provisional wastewater system" means any wastewater system or any technology, device, or component of a wastewater system that, on the basis of (i) research acceptable to the Department or (ii) approval of the wastewater system by a nationally recognized certification body for a period that exceeds one year for research, testing, or trial use under actual field conditions in this State pursuant to a protocol that has been approved by the Department.(b) Adoption of Rules Governing Approvals. - The Commission shall adopt rules for the approval and permitting of innovative, conventional, provisional, and accepted wastewater systems. The rules shall address the criteria to be considered prior to issuing an approval for a system, requirements for preliminary design plans and specifications that must be submitted, methodology to be used, standards for monitoring and evaluating the system, research evaluation of the system, the plan of work for monitoring system performance and maintenance, and any additional matters the Commission determines are necessary for verification of the performance of a wastewater system or system component.(c) Procedure for Modifications or Revocations. - The Department may modify, suspend, or revoke the approval of a wastewater system if the Department determines that the approval is based on false, incomplete, or misleading information or if the Department finds that modification, suspension, or revocation is necessary to protect public health, safety, or welfare. The Department shall provide a listing of all approved innovative, provisional, and accepted wastewater systems to the local health departments annually, and notify the local health departments within 30 days of any modification or revocation of an approval of a wastewater system or system component.(d) Evaluation Protocols. - The Department shall approve one or more nationally recognized protocols for the evaluation of wastewater systems. Any protocol approved by the Department shall specify a minimum number of sites that must be evaluated and the duration of the evaluation period. At the request of a manufacturer of a wastewater system, the Department may approve an alternative protocol for use in the evaluation of the performance of the manufacturer's wastewater system. A protocol for the evaluation of a wastewater system approved by the Department pursuant to this section is a scientific standard within the meaning of G.S. 150B-2(8a)h.(e) Repealed by Session Laws 2015-286, s. 4.15(a), effective October 22, 2015.(f) Provisional Systems. - A manufacturer of a wastewater system may apply to the Department to have the system provisionally approved for use in this State. Any wastewater system approved based on its approval by a nationally recognized certification body must be designed and installed in a manner consistent with the system evaluated and approved by the nationally recognized certification body. The manufacturer shall submit a proposal for evaluation of the system to the Department. The proposal shall contain procedures for obtaining specified information necessary to achieve innovative status upon completion of the provisional status. The proposal for evaluation shall include the design of the system, a description of any laboratory or field research or testing that will be used to evaluate the system, a description of the research or testing protocol, and the credentials of the independent laboratory, consultant, or other entity that will be conducting the research or testing on the system. The proposal may include an evaluation of research and testing conducted in other states to the extent that the research and testing involves soil types, climate, hydrology, and other relevant conditions that are comparable to conditions in this State and if the research or testing was conducted pursuant to a protocol acceptable to the Department. The manufacturer shall enter into a contract for an evaluation of the performance of the controlled demonstration wastewater system with an independent laboratory, consultant, or other entity that has expertise in the evaluation of wastewater systems and that is approved by the Department. The manufacturer may install up to 200 provisional wastewater systems on sites that are suitable for a conventional wastewater system and that have a repair area of sufficient size to allow installation of a conventional wastewater system, an approved innovative wastewater system, or an accepted wastewater system if the provisional wastewater system fails to perform properly. If the provisional wastewater system is intended for use on sites that are not suitable for a conventional wastewater system, the Department may approve the installation of the provisional wastewater system if the Department determines that the manufacturer can provide an acceptable alternative method for collection, treatment, and dispersal of the wastewater. The Department shall approve applications for provisional systems based on approval by a nationally recognized certification body within 90 days of receipt of a complete application. A manufacturer that chooses to remove its product from the nationally recognized standard during the provisional approval may continue its application in this State pursuant to requirements and procedures established by the Department.(g) Innovative Systems. - A manufacturer of a wastewater system for on-site subsurface use may apply for and be considered for innovative system status by the Department in one of the following ways:(1) If the wastewater system has been approved as a provisional wastewater system pursuant to subsection (f) of this section, the manufacturer may apply to have the system approved as an innovative wastewater system based on successful completion of the evaluation protocols established pursuant to subsection (d) of this section.(2) If the wastewater system has not been evaluated or approved as a provisional wastewater system pursuant to subsection (f) of this section, the manufacturer may apply to the Department to have the system approved as an innovative wastewater system on the basis of comparable research and testing conducted in other states. The manufacturer shall provide the Department with the data and findings of all evaluations of the performance of the system that have been conducted in any state by or on behalf of the manufacturer. The manufacturer shall also provide the Department with a summary of the data and findings of all other evaluations of the performance of the system that are known to the manufacturer.(3) If the wastewater system has not been evaluated or approved as a provisional system pursuant to subsection (f) of this section, but has been evaluated under protocol established 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.Within 30 days of receipt of the initial application, the Department shall either (i) notify the manufacturer of any items necessary to complete the application or (ii) notify the manufacturer that its application is complete.
