When Is the NC Operator Inspection Report Due?

In North Carolina, the Management Entity (the operator or company under contract to run the system) must send a copy of each inspection report to the owner, the local health department (LHD), and the manufacturer within 30 days of the system inspection. The rule is 15A NCAC 18E .1304(c). The 30 days run from the inspection date, so each visit required by Table XXXII creates its own deadline.

The report must include “results of the VIP with respect to compliance criteria as specified in the RWTS or PIA Approval and effluent sampling.” VIP is the manufacturer’s Visual Inspection Protocol. Separately, .1304(g) requires the Management Entity to “submit the inspection report to the Department centralized data management system”; that paragraph does not state a deadline. Sampling results go to the owner, LHD, Department, and the proprietary manufacturer under .1302(e).

What does the rule actually say?

15A NCAC 18E .1304(c) reads:

“The Management Entity shall provide a copy of the inspection report, including results of the VIP with respect to compliance criteria as specified in the RWTS or PIA Approval and effluent sampling, to the owner, LHD, and manufacturer within 30 days of the system inspection.”

Three points follow from that text:

1. The trigger is the inspection. The clock starts on the date of the system inspection, not at the end of a quarter or year.
2. Three recipients, one deadline. Owner, LHD, and manufacturer copies are all due within the same 30 days.
3. The duty belongs to the Management Entity. Rule .0105(58) defines it as the party “who has primary responsibility for the operation of a wastewater system,” which “is or employs the operator in responsible charge.”

Paragraph (c) names the “manufacturer” without qualification. For a non-proprietary system with no manufacturer, confirm the expected recipients with your LHD.

Which NC reports have deadlines?

Report	Rule	Recipients	Timing in the text
Inspection report (VIP results, effluent sampling)	.1304(c)	Owner, LHD, manufacturer	Within 30 days of the system inspection
Inspection report, state database	.1304(g)	Department centralized data management system	Not stated
Sampling results	.1302(e)	Owner, LHD, Department, proprietary advanced pretreatment manufacturer	Not stated
Identical component replacement performed as maintenance	.1301(h)	Owner and LHD	Within 30 days of when the activity occurs
Inspection shows repairs are needed	.1304(d)	LHD	Within 48 hours
Type IIIb or IIIh compliance inspection by a private Management Entity	.1305(d)	Owner and LHD	Every five years

What goes into the report?

The rules build the report from the inspection steps in .1302(d) for advanced pretreatment systems:

• Flow first. Under .1302(d)(4), “the actual flow shall be recorded in accordance with the RWTS or PIA Approval by the Management Entity prior to the visual inspection of the system.”
• VIP results. The VIP covers “a visual inspection and evaluation of all critical treatment components and of the effluent in the field for solids, clarity, color, and odor,” plus field tests of “pH, turbidity, and dissolved oxygen content and, for TS-II systems, alkalinity” (.1302(d)(3)(A)).
• Compliance status. The VIP includes “compliance criteria to determine system compliance status and proposed responses to conditions observed” (.1302(d)(3)(B)).
• Field parameters. For systems approved for field parameters, “The results shall be recorded in the written report” (.1709(e)).
• All samples. Under .1302(d)(5)(D), “All sample results collected shall be reported.”

The contract also governs reporting. Rule .1303(b)(1) requires it to include “specific requirements for operation, maintenance, and associated reporting.” See Does an NC aerobic system need a maintenance contract?.

What does the LHD do with the report?

Rule .1305(c) states that an authorized agent “shall review the performance and inspection reports submitted in accordance with Rule .1304(c) of this Section and perform an on-site compliance inspection of the systems as required in Table XXXII.” If a system is not malfunctioning but is out of compliance, .1305(e) directs the authorized agent to “issue a written notice of non-compliance to the owner.” Late or missing reports leave the LHD without the record it reviews.

How often does the 30-day clock run?

Once per required inspection. Table XXXII sets the minimum frequency by system type, for example 2/year for Type IVa (LPP distribution) and quarterly in the first year for Type Vc RWTS at 1,500 gpd or less. See How often are NC systems inspected?, the free calculator, and the North Carolina hub. When an inspection finds that repairs are needed, a shorter clock applies; see What must an NC operator do when repairs are needed?.
