The objective of the CSI was to gather information necessary to determine compliance with the requirements and limitations of their NPDES/SPDES permit No. NY0030074. 2.0 KEY PARTICIPANTS Listed below are key inspection participants and contact information, grouped by organization. U.S. Environmental Protection Agency Molly Hillenbrand, Lead Inspector Hillenbrand.molly@epa.gov, 732-321-4452 Robert Morrell, Geologist Village of Liberty Wastewater Treatment Plant Mark Kellam, Working Supervisor/ Operator mskellam12754@gmail.com, 845-866-1909 3.0 FACILITY DESCRIPTION 3.1 General Information The Village of Liberty WWTP is located at Willow Lane, Liberty, NY 12754 and began operations in 1985. The facility has a treatment design capacity of 2 million gallons per day (MGD) with the average flow through the plant of 0.6 MGD. The sewer connections receive wastewater from residential, commercial, and industrial sources from the Village of Liberty and an adult care facility from the surrounding Town of Liberty. The Village of Liberty WWTP employs one full-time city operator and two contracted H2O Innovation employees. The facility operates 24 hours a day, 7 days a week, with business hours Monday through Friday from 6:30 to 3:00 pm. The Village of Liberty WWTP facility is categorized as Standard Industrial Classification (SIC) 4952 - Sewerage Systems and the North American Industry and Classification System (NAICS) 221320 - Sewage Treatment Facilities. 3.2 Process Information Influent wastewater entering the headworks is intercepted by a manual bar screen to prevent large matter from entering the treatment system. Following the manual bar screen, the flow continues to the Parshall flume. The approaching flow through the Parshall flume is measured by an ultrasonic flow sensor. The wastewater continues to a mechanical bar screen to remove rags and large matters followed by aerated grit chambers allowing heavy solids to Page 2 of 5 Village of Liberty WWTP, Liberty, NY NPDES/SPDES No. NY0030074 Inspection Dates: 9/6-9/7/2023 settle out. Proceeding the aerated grit chambers, the wastewater passes through a fine screen removing material greater than 6 mm in diameter. Following fine screening, the wastewater continues to one of the two oxidation ditches. Polyaluminium chloride (PAC) is added at the oxidation ditch for phophorous removal. From the oxidation ditch, wastewater proceeds to one of the two circular secondary clarifiers. The clarified wastewater continues to Ultraviolet (UV) Disinfection Systems. Effluent is disinfected seasonally between May 15 to October 15. The treated wastewater enters a post aeration basin and is discharged to the Middle Mongaup River, located across Route 17 at Outfall 001. Grit removed from the grit removal system are collected in a dumpster and disposed of by TAM Enterprises. Solids removed from the screening processes are disposed of at the local landfill. Filtrate from screening and grit removal continues to the plant for treatment. Sludge from the secondary clarifiers is either returned to the oxidation ditch as Return Activated Sludge (RAS) or pumped into the holding tank as Waste Activated Sludge (WAS). Sludge is conveyed to the belt filter press for dewatering. The dewatered sludge is collected and disposed of by TAM enterprises. 3.3 Facility Self-Monitoring Information Permit compliance samples are collected by plant personnel. Plant personnel perform on-site analysis for temperature, settleable solids, and pH. Sample analyses for 5-Day Carbonaceous Biochemical Oxygen Demand (CBOD5), Total Suspended Solids (TSS), ammonia, Total Kjeldahl Nitrogen (TKN), total phosphorous and fecal coliforms are contracted to Sullivan County Labs, 86 Queen Mountain Rd, Ferndale, NY 12734. 4.0 EPA SAMPLING/INSPECTION ACTIVITIES 4.1 Sampling Activities An ISCO automatic composite sampler was set up at the effluent (Outfall 001) monitoring location. The automatic composite sampler was packed with ice to ensure sample preservation and programed to collect 96 sample aliquots during the 24-hour sampling period. The 24-hour composite sample was collected and analyzed for CBOD5, TSS, TKN, and total phosphorous. On-site grab samples were collected at Outfall 001 and analyzed for pH, temperature, settleable solids, and Total Residual Chlorine (TRC). Five direct-grab samples were also collected for fecal coliforms. In addition, an ISCO automatic composite sampler was set up at the influent monitoring location. The automatic composite sampler was packed with ice to ensure sample preservation and programed to collect 96 sample aliquots during the 24-hour sampling period. The 24-hour composite sample was collected and analyzed for CBOD5 and TSS. All sample containers, preservation techniques and holding times were in accordance with USEPA requirements specified in 40 CFR Part 136. All samples were transported on ice to the USEPA Laboratory in Edison, New Jersey for analysis. A chain of custody form Page 3 of 5 Village of Liberty WWTP, Liberty, NY NPDES/SPDES No. NY0030074 Inspection Dates: 9/6-9/7/2023 recorded sampling and handling activity (Attachment 1). Flow data was obtained directly from the Village of Liberty's WWTP instrumentation. The facility representative declined the EPA offer for split samples. 4.2 Inspection Activities A NPDES CSI was conducted at the Village of Liberty WWTP located at Willow Lane, Liberty, NY 12754. The inspectors met with Mark Kellam the working supervisor/operator with the Village of Liberty WWTP. Inspector credentials were presented, and contact information was exchanged. Inspectors explained to the facility's representative that the inspection was to determine if the facility is in compliance with their SPDES permit, NY0030074. A physical inspection occurred, assisted by facility staff, to observe and evaluate the wastewater treatment process, sampling and flow monitoring equipment, and effluent and influent monitoring locations. Observations and concerns were communicated to facility staff throughout the inspection and reiterated during the closing conference. Inspection findings observed through the facilities physical inspection are listed in Section 6.2. 4.3 Deviations and/or Environmental Conditions At the time of the inspection the manual bar screen at the head of the influent line was being replaced. In addition, the facility was in the process of upgrading/ installing a belt filter press. 5.0 ANALYTICAL RESULTS Village of Liberty WWTP September 6-7, 2023 Parameter Flow CBOD5 CBOD5 * CBOD5 % Removal * CBOD5 * TSS TSS * TSS % Removal * TSS Location Inf.
