The waste facility is undergoing a complete redesign since last permit renewal. The facility has added a 417,000 gallon clarifier, polishing basin, new effluent meter vault and dechlorinating station. A new 12" discharge line will empty into existing discharge point. The sludge at the bottom of clarifier will be wasted to new sand drying beds and hauled to the landfill. Enclosed is the design layout for this new plant. The backwash flow averages 100,000 gallons per day. A copy of our sludge management plan is enclosed. This new plant is at 75% completion with a finish date for February 2018. If you need any further information, please do not hesitate to contact me at (252)- 444-6420.

Ownership Status: Federal ❑ State ❑ Private ❑ Public Page 1 of 4 Version 6/2017 NPDES PERMIT APPLICATION - SHORT FORM C - WTP For discharges associated with water treatment plants 5. Type of treatment plant: ❑ Conventional (Includes coagulation, flocculation, and sedimentation, usually followed by filtration and disinfection) ® Ion Exchange (Sodium Cycle Cationic ion exchange) ® Green Sand Filter (No sodium recharge) ❑ Membrane Technology (RO, nanofiltration) Check here if the treatment process also uses a water softener 6. Description of source water(s) (i.e. groundwater, surface water) Castle Hayne Aquifer (Groundwater) - High in iron, manganese, and hardness 7. Describe the treatment process(es) for the raw water: Water from the aquifer is pumped from the well into two aeration basms. As the water cascades down through the aerator, it removes hydrogen sulfide and starts oxidation process. Next the water is injected with sodium permanganate to further oxidize the iron so greensand filters in the plant can remove it. Water leaves the filters to enter the ion exchange softeners to remove calcium & magnesium hardness. After leaving the softeners, it is blended with filter water to give desired hardness. Next it is injected with zinc orthophosphate for corrosion control, then sodium hypochlorite and ammonia to form chloramines. After processing it is then stored in a 1.0 MG ground storage tank before being sent to the system. S. Describe the wastewater and the treatment process(es) for wastewater generated by the facility: Our wastewater consists of iron, manganese, chlorides, magnesium, and calcium that both the greensand filters and ion exchanged softeners have removed The water leaves the water treatment plant, going through an influent meter to the 417,000 gallon clarifier. The sludge settles, leaving clean water on top that is decanted back to a 60,000 gallon (original) basin to settle more, leaves there, metered and then injected with calcium thiosulfate for chlorine removal, Out through a 12" line to a discharge point located on map. The sludge produced is gathered in the bottom of the clarifier with sludge arm, where we waste out the material with solids handling pumps to be applied to 6 drying beds. The water filters out, and then is pumped back up to the clarifier. Remaining sludge is dried, then removed by equipment and hauled to the landfill. 9.
