This inspection was conducted to verify that the facility is operating in compliance with the conditions and limitations specified in NPDES WW Permit No. NC0021865. A summary of the findings and comments noted during the inspection are provided in the enclosed copy of the inspection report. The Compliance Evaluation inspection was conducted by Division of Water Resources staff from the Wilmington Regional Office. The following violation(s) were noted during the inspection: Inspection Area Description of Violation Record Keeping No documentation of submittal of Annual Wastewater Reports in Division's database nor on its Laserfiche system. A Calendar Year or Fiscal Year report is required for the WWTP and for it collection system or a combined report. Aeration Basins The wastewater leak at the back -end of the original aeration basin is still leaking as was noted during the May 2019 inspection. The Town needs to hire a consultant to determine best way to evaluate and repair it. Remedial actions should have already been taken to correct these problems and prevent further occurrences in the future. The Division of Water Resources may pursue enforcement action for this and any additional violations of State law.

NCO021865 I11 12I 21/07/29 117 18 i c i Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) Town is reminded to submit a formal letter indicating what was done to permanently seal the discharge from the surge basins (old polishing ponds) by end of August to meet Special Condition A(5). Also, the Town needs to have a manner to access file reports to compare to lab analysis reports during an inspection. This can be accessing the a-DMR on -site or having printed copies available. Below are the major issues that needs to be addressed and will be included on a Notice of Violation: 1. Town still has not been filing its Annual Wastewater Performance Reports to the Division. 2. The wastewater leak at the back -end of the original aeration basin is still leaking as was noted during the May 2019 inspection. The Town needs to hire a consultant to determine best way to evaluate and repair it.

Permit has special conditions regarding use of surge basins & required freeboard and abandonment of the old outfall line from surge basins. Staff indicated they located a gravity return to treatment from surge basin closest to rest of facility, thus maintaining its freeboard should not be an issue.

A CY or FY report is required for the WWTP and for it collection system or a combined report A review of the Town's website shows the CY 2018 report for WWTP dated June 2019 as the only report being available. This issue was pointed out following the last WWTP inspection in May 2019 and probably prompted creation of the report found. The issue was also pointed out after the collection system inspection in July 2019. Laboratory Are field parameters performed by certified personnel or laboratory? Are all other parameters(excluding field parameters) performed by a certified lab? # Is the facility using a contract lab? # Is proper temperature set for sample storage (kept at less than or equal to 6.0 degrees Celsius)?
