Sincerely, David Hux Director of Water Resources Enclosures Cc: Mark Swink; Field Operations Superintendent Sibyl Brotherton; Plant Supervisor/ORC Mark Swink; Field Operations Superintendent/ORC Certified Mail 7013 1710 0001 0546 5452 www.cityofshelby.com SYSTEM OVERVIEW The City of Shelby wastewater collection and treatment system serves a customer base of 8,276 residential, commercial, and industrial users. During last year the First Broad River Wastewater Treatment Plant (WWTP) collected and treated an average of 3.37 million gallons per day (MGD); included in this flow is wastewater from Kingstown and Fallston. The sewer collection system consists of gravity sewer lines, lift stations, and force mains that convey wastewater to the First Broad River WWTP. The City owns and maintains 213.7 miles of gravity sewer and force main lines with 19 lift stations. The City of Shelby also maintains five (5) lift stations for Fallston and three (3) for Kingstown. Aerial View of the First Broad River WWTP WHAT IS WASTEWATER? Wastewater is sewage from your home's sinks, toilets, bathtubs, and washing machines. People also create wastewater at work. Offices, businesses and manufac- turers create not only domestic wastewater but also can create wastewater combined with the discharge associated with manufacturing processes or services. The City of Shelby's collection system and lift stations direct the flow of the wastewater to the First Broad River WWTP for treatment. The First Broad River WWTP is located on South Lafayette Street. HOW DO WE TREAT WASTEWATER? Wastewater treatment plants clean our wastewater and prevent pollution from getting into the environ- ment. When wastewater enters our 6 MGD facility, bar screens catch and remove trash and large objects. Grit chambers then remove heavy particles like gravel, sand, seeds, and coffee grounds. The wastewater then flows through large settling tanks called clarifiers where heavy solids settle to the bottom and are re- moved. After the primary clarifiers, the liquid portion flows into the aeration basin where microorganisms break- down the pollutants. The wastewater then flows into final clarifiers where the microorganisms settle out and are returned to the basins. The flow is disinfected before the treated water is returned to the First Broad River. The solids, which have been removed from the process, are pumped to a holding tank where they are held until they are processed through our Compost Facility, where the solids are combined with bark mulch and treated for 30+ days. After processing, the compost is provided to the public for home use around trees and flowers. The product is also being used as fertilizer for pastures. COLLECTION SYSTEM MAINTENANCE The Field Operations Division maintains collection system pipes and lines in order to prevent sanitary sewer overflows (SSOs) and keep wastewater flowing through the collection system to the treatment plant for treatment. During this report year, 32.95 miles of sewer lines (15.9%) were cleaned by rodding/jetting/bucket cleaning, 7.21 miles of sewer lines were videoed to inspect sewer lines for problems, and the City acoustic tested 1 mile for blockages. During the year, Field Operations also conducted inspections of 148 exposed aerial crossings and also performed maintenance of sewer right-of-ways. Field Operations is responsible for installation of sewer connections and also perform repairs to problem- atic connections, lines and manholes. Smoke testing is also performed to determine sources of inflow and infiltration. Plant Maintenance conducts inspections of all lift stations and performs both preventative and corrective maintenance on the stations and the force mains. The City's lift stations are equipped with alarm systems and are served with back- up generation (either permanent or portable capabilities). Dumping waste into the City's manholes without permis- sion is illegal. Residents can report suspicious activity, sewer overflows and other sewer issues any time by dialing (704) 484-6866. COMPLIANCE SUMMARY The City of Shelby's First Broad WWTP has permit limits and monitoring requirements regulated by the North Carolina Department of Environmental Quality (NCDEQ). During the year thousands of samples are collected and analyzed to document compliance and to monitor plant operations. WASTEWATER TREATMENT PLANT COMPLIANCE No violations during 2017 NCDEQ requires all wastewater collection and treat- ment systems to annually report to its customers all sanitary sewer overflows, violations of state -issued permit limits and reporting requirements. The follow- ing overflows and violations occurred from January 2017 through December 2017.

ENVIRONMENTAL PROGRAMS AND SERVICE INITIATIVE As part of a commitment to support educational awareness and promote better learning, Shelby offers tours of the wastewater treatment plant to various interest groups. For a tour of the plant, contact the Wastewater Plant Supervisor at 704-484-6850. FATS, OILS and GREASE PROGRAM Grease is a leading cause of sewer blockages and over- flows in the sewer system and can lead to sewer back- ups into homes. The City urges residents to help our fight against grease: • Never pour grease Grease (FOG) Program seeks to reduce these occur- rences by education to the public on how to prevent grease from entering the sewer system. Special emphasis has been placed on food service es- tablishments, but we all need to do our part to keep grease out of the sewer system. For more information on our program, contact the Pretreatment Coordinator at 704-484-6850.
