Becker, President Aqua North Carolina, Inc. 202 MacKenan Court Cary,NC 27511 RECEIVED/DENRJDWR JUN 2 7 2018 Subject: Compliance Evaluation Inspection - Neuse River Village Collection System Water Reng Serces Deemed Collection System Permit WQCSD0185 Permitting Section Wake County Dear Mr. Becker: On June 21, 2018, Vanessa Manuel from the Raleigh Regional Office conducted an inspection of Aqua's wastewater collection system to evaluate compliance with North Carolina Administrative Code Section 15A NCAC 02T .0403 (Permitting by Regulation). The cooperation and assistance of the following individuals during the inspection were greatly appreciated: Peter Rhodes, Regional Field Supervisor; Bobby Ball, current Operator in Responsible Charge (ORC); Chris McDonald, future ORC; Brandon Chance; Thomas Vial; and Amanda Owens, Environmental Compliance Manager. The wastewater collection system consists of one duplex pump station, one high priority sewer line and 10 manholes. The approximate feet of gravity sewer and force main have not been documented. The items below show what conditions were noted during the inspection: 1. Reported Sanitary Sewer Overflows. During the period July 1, 2016, through June 20, 2018, there were no documented SSOs from the Neuse River Village Collection System. 2. Grease Control Program. Aqua has developed and implements an educational fats, oils and grease program that includes at least bi-annual distribution of educational material targeted at residential users. 3. Pump Stations Inspected. The inspector's observations noted in the next 5 items refer to the Neuse River Village Lift Station that was inspected. Overall, the pump station was well maintained. The wet well was free of excessive debris and grease, and the inspector did not observe any signs of recent overflow. The pump station is not equipped with a permanent generator. The Neuse River Village Lift Station is equipped with a quick hookup for a portable generator. The collection system operators inspect the pump station at least weekly. 4. Pump Station Signage. The pump station has signage clearly and conspicuously posted that identifies the pump station,provides an emergency 24-hour contact telephone number(s), and provides instructions for notification if the visual alarm illuminates and/or the audible alarm sounds, or if an emergency is apparent. 5. Pump Station Restricted Access. The pump station sites, equipment and components were observed to have restricted access. • State of North Carohna I Environmental Quality I Water Resources I Raleigh Regional Office 1628 Mail service Center I Raleigh,North Carolina 27699-1628 919 791-4200 �,• :-�Ai`-._r :s��'k;- dK.F:i�. ".?..v. r . , � , Aqua North Carolina, Inc.—Neuse River Village Collection System,WQCSD0185 June 22, 2018 6. Pump Stations Automatic Polling Feature. The pump station is equipped with a telemetry system that allow the collection system operators routine contact with the pump station from a central location to check the operational status of the system. 7. Pump Station High Water Alarms. The pump station is equipped with an audible and visual high- water alarm. During the inspection, these alarms functioned properly. 8. Pump Station Inspection Program. Aqua has developed and implements a routine inspection of the pump station that includes the following maintenance activities: cleaning and removing debris from the pump station area and wet well; inspecting all valves; inspecting pumps and other mechanical equipment; and verifying the proper operation of the alarms, telemetry system and auxiliary equipment. The inspector reviewed the inspection logs of the pump station and observed adequate entries of the date and time of the operator's inspection, observations made, and any maintenance, repairs, or corrective actions taken. 9. Cleaning Sewer Lines. Aqua has developed and implements a program for cleaning the sewer lines. The ORC informed the inspector 1,425 feet of sewer line was cleaned during April and October 2017 and June 2018. 10. Overflow Response Plan. Aqua has developed and maintains an Overflow Response Plan that includes 24-hour contact numbers, response time, equipment list and spare parts inventory, access to cleaning equipment, access to construction crews, sources of emergency funds, site sanitation and cleanup materials, and post-SSO assessment. 11. SSO Records. Aqua has maintained adequate records pertaining to SSOs and sewer complaints for the three-year period ending May 31, 2018. Although there has not been an SSO from the subject collection system in the last two years, Aqua's records documented overflows in 2014 and 2015. 12. Sewer Collection System Map. Aqua has developed and maintains an up-to-date comprehensive map of its sewer collection system. The paper-based and electronic maps include pipe size,pipe material, pipe location, flow direction, number of active service taps, and pump station location. 13. Inspection of High Priority Sewer. As required by 15A NCAC 02T .0403(a)(5), an inspection of all high priority sewer lines shall be performed at least once every six-months. The high priority sewer line, which crosses a streambed, is located at the corner of the access road off Misty River Drive and the road to the wastewater treatment plant. The exposed 8-inch sewer line appears to be constructed of ductile iron with flanged joints. The pipeline appeared to be sufficiently supported and free of evidence of leakage and visible damage. This office was not aware of this high priority sewer line during past inspections of the Neuse River Village Collection System. Please ensure the sewer line is inspected at least once every six-months. Photographs of the pipeline is included as Attachment A. 14. Right-of-ways and Easeirents. As required by 15A NCAC 02T .0403(a)(9), right-of-ways and easements are maintained in the full easement width for personnel and equipment accessibility surrounding the sewer collection system.
