Graham County, NC System Description: Treatment system consists of a 5,000 gallon septic tank, flow equalization pump station, two (2) Bioclere trickling filter/settling tanks in series, two (2) automatic backwash sand filters and two (2) Ultraviolet Light Disinfection Systems. The effluent will be dispose d of by a surface drip irrigation system for a forested area on the property. An auto-dialer is provided to notify the operator of high water alanns, drip system failure, pump failures, or a power outage. The influent wastewater enters the septic tank where solids, trash and grit will be settled out and anaerobically digested. The septic tank will also act as sludge storage for the system. The wastewater flows from the septic tank to the flow equalization pump station by gravity and is pumped to the Bioclere trickling filters on a timed dose basis to minimize peak flows. The chemical feed system is connected to the flow equalization flow meter and should be adjusted as necessary to maintain pH at 7-8 in the effluent. The Bioclere trickling filters consist of a baffled settling tank under a plastic media trickling filter. Each Bioclere unit contains two dosing pumps that alternate pumping flow to the trickling filter. A third pump in each unit returns sludge collected in the settling tank to the septic tank. From the Bioclere Units the wastewater flows by gravity into the automatic backwash filter feed tank. The sand filters use suction lift pumps to draw water from the filter feed tank to the filters and then direct flow to the ultraviolet light disinfection system. Backwash is initiated automatically for the sand filters when the filter pressure is high. Backwash water is drawn from the filter backwash tank and is directed to the septic tank for treatment. The turbidimeter draws a continuous sample from the ultraviolet light system channel to detennine turbidity. If turbidity exceeds 10 NTU then the turbidimeter sends a signal to the automatically actuated valves to direct flow to the reject storage tank. Treated wastewater meeting the 10 NTU standard is directed to the filter backwash tank and overflows by gravity to the drip system dosing tank. The drip system dosing tank is connected to the effluent storage tanks (4 - 15,000 gallon tanks) by a gravity line that allows flow to fill both the effluent storage tanks and the dosing tank equally. The dosing tank will pump the flow through the drip system hydraulic unit which contains automatically actuated valves controlled by the drip system control panel. The drip hydraulic unit will direct flow to two (2) of the four (4) system zones simultaneously when dosing and will record flow irrigated in the zones. The drip system will automatically flush the drip lines one zone at a time based on the number of doses discharged. Water flushed through the drip lines will be returned the septic tank for treatment. Drip system shall not be utilized during freezing temperatures or precipitation events. General Maintenance: All components of the system should be inspected at a minimum on a weekly basis. Inspections shall include verification that all pumps are operational. Any pumps that are not perfonning properly should be repaired or replaced as quickly as possible. Determine Operations and Maintenance Plan Pg. 1 if water levels are normal and storage capacity remaining. If water levels are abnormal verify appropriate valves are open and lines are not clogged. pH levels should be monitored and chemical feed system for pH adjustment calibrated as necessary to maintain 7-8 pH in the system. Treatment Units Maintenance Descriptions A. Septic Tank Maintenance: Septic tank shall be pumped by a septage hauler a minimum of one (1) time per year. During septic tank pumping the effluent filter shall be removed and inspected. Effluent filter should be cleaned or replaced as necessary. B. Flow Equalization Pump Station Maintenance: Pump flow rates should be monitored if any significant decrease in flow occurs pump should be pulled and inspected for wear. Wetwell should be pumped down and hosed out a minimum of once per year to prevent solids accumulation. C.- . Treatment System Refer to manufacturer's recommendations for maintenance of Aquapoint Bioclere Trickling Filters, Automatic Backwash Sand Filters, and Ultraviolet Light Disinfection System. D. Drip Irrigation System Drip irrigation system shall be inspected visually a minimum of once per week. Operator shall walk the field and check for any wet areas or other signs of damaged lines a minimum of once per quarter. Operator should monitor flows to each zone carefully and note any increases that may indicate damaged lines or decreases in flow that could indicate a clogging problem. Operations and Maintenance Plan Pg. 2 DocuSign Envelope ID: 2BA80534-958A-404B-AF45-2A59FBE2063F INSTRUCTIONS •All the equipment in the system shall be maintained by the Operator in accordance with the manufacturer’s manuals and guidelines including annual reports. •Manufacturer’s manuals and guidelines are kept at the Operating Control Building. •All reporting required as per the permit shall be submitted to NC DEQ in a timely manner. •In the event of a spill or surfacing of liquids within the development, the owner or Operator shall take the following actions: 1.Report the time of the spill or notifications of the spill to NCDEQ. 2.Report the location of the spill to NCDEQ. 3.Determine if the spill is either untreated sewage or treated effluent and report to NCDEQ. 4.Notify the hazard waste containment company and place on stand-by. 5.Determine the cause of the spill and make repairs as soon as possible. ______________________ Operating and Management Plan Environmental Inc. will be the Responsible Operator in Charge, ORC, for the entire project. Tim Barbee will work as a factory-certified sub-contractor for them on the American Manufacturing surface-drip portion of the system. He will perform scheduled inspections on this portion of the system and will provide written documentation of inspections, repairs, adjustments, etc. that are made or that will be required to be made Environmental Inc will perform operations and maintenance on the septic tanks, treatment tanks, flow equalization tanks, pump tank, sand filters, UV lights, turbidity meter, generator, and general maintenance on the equipment building. (The following numeration refers to the January 9, 2023 letter from Lauren Raup-Plummer of the North Carolina Department of Environmental Quality. Tim Barbee will be responsible for the drip system pumps and floats located in the pump tank, the headworks unit and control panel for the drip system located in the equipment building, and the surface drip-dispersal tubing and field hardware located on the hillside between the tankage area and the lower lake road. Item F. 1. c: Done by surveyor. This information is very accurate as shown on the original permit drawings from 2007. Item F. 1. d: Anticipated maintenance will include having to repair tubing that is damaged by rodents, tree limbs that fall, etc. Over time, floats, pumps, solenoid valves, etc. will fail. Operator will keep a sufficient amount of tubing, blanking, connection hardware, solenoid valves, flow meter, pump, and floats in stock . Routine maintenance will include checking all of these system components as well as flushing field lines. Item F. 1. e: Environmental Inc will keep all tanks, monitor wells, and the equipment building locked. Bollards or rocks will be placed in strategic locations to prevent vehicular traffic from being able to drive over the tank area. Access to the nature trail will be restricted immediately in the event there is a short-term major failure of the disposal system due to a large tree uprooting, etc. that damages or destroys a portion of the system. Item F. 1. f: Environmental Inc. has a plan in place for a major sewage spill and contact phone numbers to all the necessary responding agencies are provided above.
