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 2023 are in compliance with 40 CFR Part 503 Federal Regulations, 15A NCAC 2T rules. All biosolids produced during the 2023 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 2023 calendar year, the average temperature and time for biosolids processed through the Class A thermophilic process was 139.71 F and 7 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, 2023 through December 31, 2023. The review confirms the following: Average daily wastewater flow 7.65 MGD Average daily dry tons biosolids recycled 2.7 Dry Tons Average volatile solids reduction thru anaerobic digestion 60.0% Average anaerobic (total) digestion time 39 Days FECAL COLIFORM JAN-FEB MAR -APR MAY-JUN JUL-AUG SEP-OCT NOV-DEC Class A max 145 107 95 107 92 86 Class A avg 31 53 70 46 27 80 PARAMETER JAN-FEB MAR -APR MAY-JUN JUL-AUG SEP-OCT NOV-DEC Percent Solids (%) 1.63 1.86 2.30 1.78 1.64 2.21 Arsenic (As) 6.13 <2.69 2.73 <2.69 3.82 <11.3 Cadmium (Cd) 1.18 0.634 0.713 <2.69 0.915 <1.13 Copper (Cu) 244 204 221 31.9 307 305 Lead (Pb) 9.75 7.1 9.52 <1.4 11.8 10 Mercury (Hg) 0.491 0.0968 0.413 0.0174 0.445 0.149 Molybdenum (Mo) 6.13 2.96 1.4 <1.4 5.23 <5.56 Nickel (Ni) 17.7 11.9 13.4 4.0 17.2 17.2 Selenium (Se) 9.2 <2.69 <2.69 <2.69 <3.05 <11.3 Zinc (Zn) 779 640 678 103 866 1000 Aluminum 57,800 24,400 65,200 6,850 55,200 65,200 Calcium 20,600 16,500 15,600 5,900 14,000 15,100 Magnesium 5,780 4,870 4,910 3,310 4,420 4,840 Potassium 11,500 8,920 8,040 6,070 6,830 6,610 Sodium 8,220 6,080 4,390 6,070 7,380 <5660 SAR 1.665 1.458 1.191 2.093 1.784 1.525 ORANGE WATER AND SEWER AUTHORITY (OWASA) MASON FARM WASTEWATER TREATMENT PLANT SIMPLIFIED ANAEROBIC DIGESTION PROCESS FLOW SCHEMATIC Primary Sludge & Waste Activated Sludge 4 4 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 PUMP 2nd STAGE TEMPERATURE RANGE (THERMOPHILIC TEMPERATURE) ANAEROBIC 135 F - 140 F DIGESTER #3 BATCH FEED & DISCHARGE, HEAT EXCHANGER & HOLD BATCH - REQ'D.
