WQ0021828 MASON FARM WASTEWATER TREATMENT PLANT ORANGE WATER & SEWER AUTHORITY - CHAPEL HILL, NC The Orange Water and Sewer Authority (OWASA) owns and operates the Mason Farm Wastewater Treatment Plant located in Chapel Hill, North Carolina (NC). This facility serves the Chapel Hill, Carrboro communities including the University of North Carolina at Chapel Hill; all of which are located in southeastern Orange County. The plant discharge is regulated by NPDES Permit NC0025241. The Class A land application program is regulated by Non - Discharge (Permit No. WQ0021828) issued by the State of North Carolina Department of Environmental Quality - Division of Water Resources. This report documents that the biosolids generated during calendar year 2022 are in compliance with 40 CFR Part 503 Federal Regulations, 15A NCAC 2T rules. All biosolids produced during the 2022 calendar year were of Class A quality, therefore no Class B was land applied. If there are any questions regarding this submittal, please contact me at your convenience.

The four anaerobic digestion tanks provide approximately 1,800,000 gallons of digestion capacity and are operated in series. Normally the first three anaerobic digesters are maintained in the thermophilic temperature range, in excess of 1250 F and the fourth anaerobic digester is operated in the mesophilic temperature range, less then 115' Fahrenheit. For the 2022 calendar year, the average temperature and time for biosolids processed through the Class A thermophilic process was 139.61 F and 11 hours. The digester operation -temperatures, recirculation and mixing rates are monitored continuously, in addition to gas production. Process control testing (VA/ALK ratios, pH and alkalinity, etc.) is checked routinely. Transfers into and out of the various digester tanks are monitored and recorded. The Mason Farm Wastewater Treatment Plant anaerobic digestion operating conditions have been carefully monitored for the period of January 1, 2022 through December 31, 2022. The review confirms the following: Average daily wastewater flow 7.2 MGD Average daily dry tons biosolids recycled 3.0 Dry Tons Average volatile solids reduction thru anaerobic digestion 60.1% Average anaerobic (total) digestion time 40 Days FECAL COLIFORM JAN-FEB MAR -APR MAY-JUN JUL-AUG SEP-OCT NOV-DEC Class A max 93 107 89 81 87 98 Class A avg 21 36 29 27 49 21 PARAMETER JAN-FEB MAR -APR MAY-JUN JUL-AUG SEP-OCT NOV-DEC Percent Solids (%) 2.03 1.6 1.95 2.20 2.60 2.01 Arsenic (As) <2.46 3.43 15.4 <4.55 4.27 <4.98 Cadmium (Cd) 1.13 0.94 5.13 1.09 1.02 0.0891 Copper(Cu) 223 251 166 163 302 257 Lead (Pb) <2.46 20.5 13.3 12 11.7 11.6 Mercury (Hg) .00985 0.01 0.108 <0.0182 0.0231 0.0383 Molybdenum (Mo) 5.12 5.84 20.5 <2.27 5.27 <2.49 Nickel (Ni) 11.4 14.4 10.3 10.0 14 15.1 Selenium (Se) 5.37 3.93 20.5 <4.55 6 <4.98 Zinc (Zn) 788 756 518 750 781 990 Aluminum 87700 49,500 31,800 44,000 52,700 56,200 Calcium 17389 19,400 13,700 17,500 17,700 24,900 Magnesium 5172 5,750 3,910 4,860 4,920 7,010 Potassium 8966 8,000 6,140 7,180 7,620 10,700 Sodium 5420 7,000 4,250 5,680 5,460 7,960 SAR 1.321 1.435 1.151 1.452 1.509 1.628 ORANGE WATER AND SEWER AUTHORITY (OWASA) MASON FARM WASTEWATER TREATMENT PLANT SIMPLIFIED ANAEROBIC DIGESTION PROCESS FLOW SCHEMATIC Primary Sludge & Waste Activated Sludge RDT = ROTARY DRUM THICKENER RDT RDT #1 #2 (COLD, THICKENED SLUDGE TO DIGESTION) n 1 ST STAGE TEMPERATURE RANGE (THERMOPHILIC TEMPERATURE) ANAEROBIC 135 F - 140 F [DIGESTER #4 CONTINUOUS OR BATCH FEED, HEAT EXCHANGER & BATCH DISCHARGE RECIRCULATION PUP M 2nd STAGE TEMPERATURE RANGE (THERMOPHILIC TEMPERATURE) ANAEROBIC 135 F - 140 F DIGESTER #3 BATCH FEED & DISCHARGE, HEAT EXCHANGER & HOLD BATCH - REQ'D.

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL -Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean -Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis ofAcrolein and Acrylonitrile by EPA Method 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes. TNI - The NELAC Institute. ANALYTE QUALIFIERS M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery. N2 The lab does not hold NELAC/TNI accreditation for this parameter but other accreditations/certifications may apply. A complete list of accreditations/certifications is available upon request. R1 RPD value was outside control limits.
