The City of zings . vlountain serves apopulation of approximately 10,933 people and4,565 water Customers which consist of an average of 4,289 Residential and 276 Commercial. The Collection System operates under the permit #1WQCS00036 issued by the State of North Carolina. On average the City collects 1,697,00o gallons of wastewater (55°o Domestic/Commercial and45% industrial Process) each day and transports it through 113 miles of gravity collection lines, 37 miles of force mains and 35 pumping stations, and approximately 2,26o covered manholes, to the Pilot Creek -Wastewater Treatment Plant. The City's goal is to have zero spills and overflows from its Collection System. Unfortunately, because pumping stations are mechanical devices and-sewer collection systems are subject to clogs from grease, roots, construction debris and Litter, all systems are subject to spills and overflows. 7IPage WAS7TWATER COLLECTION' In order to help prevent spills and overflows, the City uses television equipment to visibly inspect lines and routinely flushes lines to help prevent future problems. Since June 2019, the collection department has cleaned 2o5,o89 feet of sewer lines and5,328 feet of lines have been videoed: In addition, a Sewer Overflow Response Plan has been prepared that identifies equipment, supplies and on-call employees that are available to help mitigate spills andprocedures to follow should an overflow occur. The City of_Kings Mountain 'Wastewater Collection System have had 9 spills between July 2019 and June 2020. The City of_Kings Iviountain s Collections Department has replaced the Beason Creek pump station going from woo gpm to moo gpm. new bar was also installed at this location. The Collection Department replaced 8o feet of 24 inch sewer main lines and installed two new manholes. Wage PUBLIC NOTICES Residents can help minimize future overflow events by reporting unauthorized uncovering of sewer manholes, improper disposal of materials into manholes, vandalism of manhole structures, any observed overflow or spills, and strong sewage odor in or around sewer lines to the City of icings Mountain at 704-734- 0333 The City of icings Mountain's website contains a flyer for the public stating the harm of pouring oil and grease into drains which lead to the collection system.

The (NPDES) Permit Number for this facility is .NCoo2o737. This facility is located off'U.S. Highway 74 Bypass, West of zings Mountain (Cleveland County). PROCESS DESCR.IPTIOX 'When wastewater is dischargedfrom a home, industry, etc.,flow travels through miles of underground lines by gravity or conveyed by pumps. This process is called a Collection System. Once the wastewater enters the facility it contains organic and inorganic material which, at this time, consist of approximately forty percent (45%) Industrial 'Wastewater. The wastewater is lifted approximately thirty two (32)foot by one of two (1 of 2) Spiral Screw Pumps. Wastewater then travels through a (Mechanical Step Feed) Bar Screen, where debris is removed; compacted, and discharged into a dumpster for disposal It then travels through a ParshallFlume with a twenty four (24) inch throat, which includes a staff gauge, and a flow meter, allfor measuring the incoming flow. ..4 24 12 IPage hour circular chart,p3-Imeter is also install-eclat the Influent. As the wastewater travels through the throat of the ParshallFlume a flow proportional refrigerated twenty four (24) hour composite sample is collected for analysis. The wastewater then enters a Splitter Box (Diversion Box) that splits the flow into three (3) Aeration Basin's based on their design flow. Sodium Hydroxide (50% Caustic Soda), is added at the diversion box to adjust the incoming pH and alkalinity to the aeration basins. Once the fresh wastewater enters the aeration basin the organic material is consumed by the microorganism. The aeration basins are equipped with floating diffusers, which supplies oxygen and mixing for the microorganism to survive. The detention time in these basins are approximately four (4) to seven (7) days. This process is called activated sludge. The activated sludge then enters at the center well of the secondary circular clarifier(s), which is where the microorganism settle at the bottom to digest the organic material that was consumed in the aeration basin. The detention time in these clarifier(s) are approximately two (2) to four (4) hours. i4s the activated sludge settles in the clarifier's, aportion of it is either returned to the head of the aeration basin 13 IPage (RilS) or wasted(1/17 AS) to the aerobic holding tank for disposal by pumps. As the treated wastewater leaves the clarifiers, it then enters a Chlorine Contact Basin, where Chlorine Gas is injected to kill the disease causing bacteria (Fecal Conform), before leaving the facility. These contact chambers are equipped with baffles (walls) to provide enough contact time. The flow exit's these chambers over a rectangular weir or a 'V Notch weir, which has a staff gauge and a flow meter that sends a signal to a totalizer. As the three (3) effluent flows combine into a manhole, Sulfur Dioxide Gas is injected to remove the residual chlorine. The flow continues to travel to the plants effluent flow proportional twenty four (24) hour refrigerated composite sampler, where a sample is collectedfor laboratory analysis. . new flow meter has been installed at the final effluent of the facility. This facility is also equipped with a waste pump station that has two (2) grinder pumps that conveys the floatable solids from the clarifiers back to the head of the Influent. .Also included is a wash water pump station that pumps treated wastewater to the Belt Filter press 14 IPage which is used to operate our 2.2 meter XCamp Press. This xlamp Press is used to dewater the waste activated sludge. This press produces a dry sludge cake of approximately 15 to 18 0. A. dry polymer is used in the polymer system that mixes with the waste sludge to form a floc so the water can drain through the pores in the belts. The disposalprocess includes two (2) aerobic holding tanks which are gravity fed to the disposal sludge pump station. These pumps convey the waste sludge to the belt filter press for operation. Once the dry cake leaves the belt filter press, it travels up a conveyor belt, through a hopper, into a tandem truck and is hauled to the Cleveland County Landfill-for final disposal. This is a lined landfill. 15 IPage 'VIOLATIONS OR DEFICIENCIES FOR PILOT CREE.x 1471WVTP JULy ol, 2019 - J'WJ' E30, 2020 MONTH/YEAR RESULTS JI Ly 2019 NONE A1,1G UST 2019 .Arsenic violations SEPTE.MBER 2o19 NONE OCTOBER 2019 CC2 & N3-C3 NO'VEJVIBER 2019 NONE DECEMBER 2019 NONE J N U.ARy 2020 Inspection- #3 weirs need replaced and dead spots found in aeration basins.
