REGAN Secretary LINDA CULPEPPER Director NORTH CAROLINA Environmental Quality July 8, 2020 Mr. Shederick Mole NCDENR - Division of Parks and Recreation 280 State Park Road Apex, NC 27502 Subject: Permit No.WQ0000488 Jordan Lake State Recreational Area - Vista Point Wastewater Irrigation Chatham County Dear Mr. Mole, Staff of the NC Division of Water Resources (DWR), Water Quality Regional Operations Section inspected the subject wastewater irrigation system on June 26, 2020. I wish to thank William Baker for his 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. The site was not visited in person. All records were reviewed. The ORC answered questions about the operation and condition of the facility. The facility is closed due to the corona virus. All lift stations have new pumps, controls, power supplies and telemetry installed. The lift station alarms, controls, floats and alternating relays are checked weekly even though the facility is not in use. The pumps, alarms, controls, floats are reportedly in working order. The lift station by the bathhouse was raised in 2019 to prevent it from flooding. There is a small float operated pump station with an alarm for the building at the WWTP. The facultative wastewater lagoon had a freeboard of 2.9 ft and the storage lagoon had a freeboard of 3.6 ft. The berm mowed and is surrounded by a locked fence. Sludge was last removed from the lagoon in February, 2014. The aerator is reportedly in working order. A tank of liquid chlorine and pump are kept in the building on site. The chlorine is injected into fresh water which runs through a pipe into the wet well. The pumps, controls, floats and valves are reportedly in working order. The effluent meter is reportedly in working order. A flow rate/pressure indicator is also present and can be used to detect clogs or breaks in the sprayfield.
