This inspection was conducted to verify that the facility is operating in compliance with the conditions and limitations specified in Non-discharge Permit No. WQ0005763. The findings and comments noted during this inspection are provided in the enclosed copy of the inspection report entitled "Compliance Inspection Report". There were no significant issues or findings noted during the inspection and therefore, a response to this inspection report is not required. If you should have any questions, please do not hesitate to contact Melanie Kemp with the Water Quality Regional Operations Section in the Asheville Regional Office at 828-296-4500 or via email at melanie.kemp@deq.nc.gov.

Stan Bryson, TWSA Wastewater Treatment Plant Operations Superintendent, was present for the inspection. Overall, the facility was operating in compliance with non-discharge permit WQ0005763. A mix of residuals from multiple TWASA plants (#1, #2, #3, and Whittier) are stored in 2 digestors on site. Plant #1 is the only facility that accepts septage as well, which enters the plant at the barscreen. After being thickened in the digestor, the sludge is mixed with a polymer before being belt pressed (flow is measured going into the belt press). From there, residuals are mixed in a batch hopper and cycled in batches through the dryer. Steam from the dryer goes through a condenser. An internal thermometer is collecting temperature readings from the dryer to ensure VAR requirements are met (alternative 8 is utilized). From there, dried residuals are stored in a silo before being distributed. Samples are collected from the silo before distribution. The dryer was offline for many months in 2023, and residuals that could not be processed were landfilled. Processed residuals are mostly provided to a few local farmers for land application. Distribution records were available for review. Bench sheets, hauling records, and residuals sampling data was available for review. The facility sampled source residuals for TCLP in November 2022 (required to perform annually). Dried tons are calculated by estimating the weight of each dried load of residuals based on % solids readings. Typically, the calculated dried tons totals do not match the estimated tons distributed to the public when provided in the annual report. A review of the 2022 Annual Residuals Report will be provided separately.

Are GW samples from all MWs sampled for all required parameters? Are there any GW quality violations? Is GW-59A certification form completed for facility? Is a copy of current permit on-site? Are current metals and nutrient analysis available? Are nutrient and metal loading calculating most limiting parameters? a. TCLP analysis? b. SSFA (Standard Soil Fertility Analysis)? Are PAN balances being maintained? Are PAN balances within permit limits? Has land application equipment been calibrated? Are there pH records for alkaline stabilization? Are there pH records for the land application site? Are nutrient/crop removal practices in place? Do lab sheets support data reported on Residual Analysis Summary? Are hauling records available? Are hauling records maintained and up-to-date? # Has permittee been free of public complaints in last 12 months? Has application occurred during Seasonal Restriction window? The 2023 residuals data was reviewed and is in compliance, thus far. TCLP samples were collected in November 2023. The 2022 Residuals Annual Report was reviewed prior to the inspection and a seperate inspection report will be provided. Comment: Pathogen and Vector Attraction Yes No NA NE a.

Bench-top Aerobic/Anaerobic digestion results In 2022, 7 fecal coliform samples were analyzed and were below limits. The same protocol will be followed in 2023. Comment: Treatment Yes No NA NE Check all that apply Aerobic Digestion Anaerobic Digestion Alkaline Pasteurization (Class A) Alkaline Stabilization (Class B) Compost Drying Beds Other A hot oil dryer dries the solids after being belt pressed. They are then stored in a silo.Comment: Sampling Yes No NA NE Describe sampling: Bacteria and %solids/metals/nutrient samples are collected from the silo prior to distribution. Samples are collected from each dryer run to ensure compliance with VAR alternative 8 and PFRP (heat drying). Is sampling adequate? Is sampling representative? The dryer was not operational for the first few months of 2023. Solids that could not be stored were sent to a certified landfill in Georgia. Comment: Page 4 of 4
