3.1. Description of Need The City of Rock Hill (City) owns and operates the Manchester Creek Wastewater Treatment Plant (MCWWTP) located at 310 Red River Road, Rock Hill, SC. The MCWWTP is authorized to discharge treated wastewater into the Catawba River in compliance with all terms outlined in NPDES Permit No. SC0020443. As part of the routine operation of the MCWWTP, biosolids are generated and must be disposed of in accordance with state and federal regulations. Dewatering is performed using two (2) 2002 2.0 Meter BDP model 3DP belt filter presses. Current biosolids disposal is permitted through incineration via contract with the Water and Sewer Authority of Cabarrus County (WSACC) (Monday – Friday, 8:00 am - 2:00 pm) and through landfilling at one of two Republic Landfill sites (Concord, NC and Union County, SC). The City also has disposal options at the Anson Landfill located in Polkton, NC. In FY21, approximately 11,200 tons of biosolids were sent to WSACC, and approximately 6,200 tons were sent to Anson. McGill picks up approximately 2-4 trucks/week. MCWWTP is currently under construction and will be for the term of this contract. Some activities will impact the dewatering building and the processes housed within it. Advanced notice for coordination of such activities will be provided to the selected contractor in order to continue dewatering operations. The City currently contracts services for the operation of the two City-owned belt filter presses for biosolids dewatering and disposal at the WSACC, Republic, Anson County, and McGill landfills. The contractor is responsible for the transportation of materials to all landfills except McGill. The City of Rock Hill will determine when or if an additional belt filter press is needed for processing biosolids. It is also at the City's discretion to determine if longer hours and/or additional loads are needed. 3.2. Services Required A.
