DANIEL SMITH !hector NORTH CAROLINA Environmental Quality March 11, 2020 Dave Mumford - Park Superintendent NCDENR Division of Parks and Recreation 13304 Creedmoor Road Wake Forest, NC 27587 Subject: Permit No.WQ0005426 Holly Point State Recreation Area Wastewater Irrigation System Wake County Dear Mr. Mumford, Staff of the NC Division of Water Resources (DWR), Water Quality Regional Operations Section inspected the subject wastewater irrigation system on March 5, 2020. I wish to thank Curtis Tyree and Brian Murphy for their help during the inspection. The purpose of the visit was to conduct a compliance inspection of the system as part of the permit renewal process. Curtis Tyree is the ORC and Vinny Shea is the Backup. Brian Murphy will also be backup. The facility is permitted to treat 6295 gpd and it treated 300 to 4500 gpd in 2019. The facility is permitted to irrigate 33.8" lyr to the sprayEields. Twelve month floating totals ranged from 7 to 22" !year in 2019. There are basket strainers in each lift station that are cleaned once a month in summer. Volume of influent is calculated by pump run times and pump rates of each of the 4 lift stations and the main lift station. The pump rate of each lift station is calibrated yearly. The concrete and steel in the lift stations has degraded over the years of service. There is a plan to rebuild all the lift stations at Holly Point, Rollingview and Sandling Beach SRA's. Several lift stations were checked during the inspection. All was in working order except that the visual high level alarm on the dump station worked, but the audible alarm was broken. Staff will have it repaired. The treatment facility is surrounded by a fence and a locked gate. The facultative lagoon had a freeboard of 2.5 feet and the storage lagoon had a freeboard of 2.9 feet. The lagoons are concrete lined. The berms and vegetation were in good condition. The aerator is in working order but has been turned off for winter. A simple check for lagoon sludge depth a year or two ago showed very little sludge accumulation. The concrete chlorine contact chamber was in good condition. A homemade chlorinator using a garden hose running water into a perforated container of chlorine tablets has been working well to produce a 1 or 2 ppm chlorine residual. The in line totalizer flow meter has been calibrated. North Carolina Department of Envirunmcntal Quality ' Division of Water Resot.— Raleigh Itc9ional Officc 13800 Barrett Drive Raleigh, North Carolina?Tb09 90_791.4200 One zone of the sprayfield was irrigated during the inspection. One seal on the aluminum pipe system needed replacing and several heads were partially clogged. Seals periodically need to be replaced and are kept in stock. The ORC reports that heads are found to be clogged with frog bones after every spray event and that they are cleared frequently. There is a plan to attempt to exclude frogs from the open chlorine contact chamber with a wall around the perimeter, or with additional screens near the outlet. Wells were in good condition and are sampled by Statesville Analytical. Records have been submitted complete and on time. Facility records were in good order. On the day of the inspection, the facility appeared to be operating in compliance with permit conditions.
