Who Needs NC Subsurface Operator Certification?

Last verified Oct 8, 2026

In North Carolina, any system that Table XXXII of 15A NCAC 18E .1301(b) assigns to a certified operator, including LPP (Type IV) and advanced pretreatment (Types V and VI), must be run by a Management Entity that is or employs a certified operator. Rule .1304(a) sets the minimum: the operator “shall, at a minimum, be certified as a subsurface operator in accordance with G.S. 90A, Article 3, and 15A NCAC 08G.” The certificate is issued by the Water Pollution Control System Operators Certification Commission (WPCSOCC).

For proprietary advanced pretreatment, the Management Entity also needs the manufacturer’s written authorization. The path is a training school (NC State lists a 3-day school at $750), an exam ($101.00 including certificate), an annual $53.00 renewal per certification paid by December 31, and six contact hours of approved training each year.

What do the rules require of the Management Entity?

Rule .0105(58) defines the Management Entity and says it “may be the owner, a public Management Entity, a certified operator, a management company, or an entity that employs certified operators. The Management Entity is or employs the operator in responsible charge for the wastewater system.”

Rule .0303(f): “The Management Entity, or its employees, shall hold a valid and current certificate or certifications as required for the system from the Water Pollution Control Systems Operators Certification Commission.”

Rule .1304(a) allows more for complex systems: “Operators of systems classified as Type V or VI in Table XXXII in Rule .1301(b) of this Section may be required to have additional certifications by the Department.”

The statute backs this up. G.S. 90A-44: “No person shall perform the duties of a water pollution control system operator in responsible charge without being duly certified under the provisions of this Article.” G.S. 90A-38(b) carves out conventional systems: “No certificate shall be required under this Article to operate a conventional septic tank system.”

What changes for proprietary systems?

Rule .1302(c): “For proprietary advanced pretreatment systems, the contract shall be with either the manufacturer, manufacturer’s representative, or a Management Entity authorized in writing by the manufacturer or manufacturer’s representative to operate the system.” For non-proprietary advanced pretreatment, the contract is with “an operator certified in accordance with Rule .0303(e) of this Subchapter for the classification indicated on the OP.”

Rule .1712(a): “Designers, installers, and Management Entities shall be authorized in writing by the manufacturer when required in the PIA Approval.” Under Rule .1712(b), manufacturers give the Department and LHDs a list of authorized Management Entities and “update this list annually.” Being certified does not put you on that list; the manufacturer’s authorization does. See the contract rule.

How do you get certified?

15A NCAC 08G .0407: “An applicant for certification as a Subsurface Water Pollution Control System Operator shall have successfully completed approved training for subsurface water pollution controls system operators.” The applicant must also meet one of four conditions: one year of experience operating a subsurface system, a two- or four-year degree with six basic science courses, a private homeowner operating only their own system, or a valid Grade II or higher biological operator certification. DEQ’s exam page adds that applicants must “be 18 years old and hold a High school diploma or GED equivalent.”

NC State’s school page states: “Completion of the training school is a prerequisite for the certification examination.” Exams are “administered by the staff of the Water Pollution Control System Operators Certification Commission (WPCSOCC) on a quarterly basis at five locations throughout North Carolina,” and “The examination application and fee must be submitted directly to the WPCSOCC 30 days prior to the desired examination date.”

How does renewal work?

G.S. 90A-46.1: “A certificate issued under this Part expires on 31 December of the year in which it is issued or renewed.” 08G .0701(a)(2): “Each operator shall provide documentation of six contact hours of Commission approved training during each year following the year of initial certification.” DEQ’s renewal page adds: “You need to have your 6 Continuing Education credits to use the online payment.” Under 08G .0701(b), a certificate invalid for two or more consecutive years requires passing the exam again.

Who must be designated for each system?

15A NCAC 08G .0201 requires owners to designate an operator in responsible charge (ORC) and a Back-up ORC, “with the exception of no Back-up ORC is required for systems whose minimum visitation requirements are twice per year.” For subsurface systems, the Operator Designation Form goes “to the local health department for owners of subsurface systems.”

Is this the same as an installer or inspector certificate?

No. NC State’s page states: “The Subsurface Wastewater Operator School is an entirely separate certification program from the Onsite Wastewater Contractor (Installer/Inspector) certification.” Installers and inspectors are certified under G.S. 90A, Article 5.
