Director Mr. Kirk Bradley Eco Tip West, LLC PO Drawer 9 Sanford, NC 27331 NORTH CAROLINA Environmental Quality June 3, 2022 Subj ect: Compliance Evaluation Inspection Eco Tip West WWTP NPDES Permit No. NC0001899 Chatham County Dear Mr. Bradley: On March 11, 2022, Cheng Zhang of the Raleigh Regional Office (RRO) conducted a compliance evaluation inspection of the subject facility. The assistance provided by Ms. Amanda Grenier, the operator in responsible charge (ORC), was greatly appreciated as it facilitated the inspection process. The inspection report is attached. The following observations were made: Eco Tip West WWTP is permitted to discharge at a rate of 0.244 MGD of wastewater from Outfall 001 into Haw River, classified WS-IV waters in the Cape Fear River Basin, and stormwater, steam condensate, and overflow from two fire ponds from Outfall 002 into Shaddox Creek, classified WS-IV waters in the Cape Fear River Basin. 1. The current permit became effective on March 1, 2022. Many treatment components listed in the permit either are not present/demolished (such as sanitary bar screen, grinder, and lift station, coagulant addition system, conventional water treatment plant with chemical addition systems, and the 18500 gallons clarifier), or are abandoned and no longer in service (process wastewater lift station and 1,200 gallons mixing/neutralization chamber with automatic pH control). 2. The facility stopped production in 2015 and has been in the process of demolition since. There has been no process wastewater generated from the facility. There was a process cooling water (containing ethylene glycol and antimony) spill in March 2014, spilled material was contained in the stormwater pond. Discharge from the stormwater pond to Outfall 002 was stopped (valve at the discharge pipe was closed) since the spill. Water from the stormwater pond is pumped to the spill pond adjacent to the aeration basin. Water from the spill pond is treated in the following treatment units: aeration basin, secondary clarifier, polishing pond, contact chamber and discharged to Outfall 001. It was noted that the original effluent pipe has been clogged significantly (with capacity of less than 20 gallons/minute). When flow exceeds the capacity, effluent has to be pumped (with a portable pump) to the water intake station (using the existing water intake pipe) and then to Outfall 001 through layflat hose. It was noted that at the time of inspection the two surface aerators were not operable. There was hardly any activated sludge in the aeration basin.

It was noted that monitoring at Outfall 002 resumed since January 2019. However, aluminum and zinc were analyzed only once (in January 2022) at the time of inspection. It was also noted that upstream and downstream monitoring at Outfall 001 has not been conducted since December 2017. 4. The ORC maintains a daily logbook. Lab results, chain -of -custody forms, and DMRs were complete and current, kept in good order and ready for review. July 2021 and January 2022 DMR data were compared to lab bench sheets; no data transcription errors were noted. Effluent flow meters were calibrated quarterly. Since CWT related process wastewater is no longer generated at the site, monitoring of parameters listed in Part I A. (2.) is not needed. 5. Field lab parameter (Certificate No. 5024) calibration and analysis records were reviewed during the inspection. 6. It appears that the main purpose to keep the facility in operation is to slowly mix/dilute the contaminated water contained in the stormwater pond with stormwater and let it discharge into the Haw River. Therefore, it is strongly recommended that the facility include antimony in the monthly monitoring at Outfall 001. Please respond in writing to RRO within 30 days of receipt of this letter regarding Items 2, 3, and 6. If you have any questions regarding the attached reports or any of the findings, please contact Cheng Zhang at: (919) 791-4200 (or email: cheng.zhang@ncdenr.gov).

Many treatment components listed in the permit are either not present/demolished (such as sanitary bar screen, grinder, and lift station, coagulent addition system, conventional water treatment plant with chemical addition systems, and the 18500 gallons clarifier), or abandoned and no longer in service (process wastewater lift station and 1,200 gallons mixing/neutralization chamber with automatic pH control). Very small amount of sanitary sewage is generated on site (two toilets/sinks from the operation building and a modular building. It appears that the main purpose to operate the plant is to treat the contaminated water from the stormwater pond resulted from a process cooling water (containing thylene glycol and antimony) spill in March 2014. Water from the stormwater pond is pumped to the spill pond and mixed with stormwater, water from the spill pond is pumped to the aeration basin and then to the clarifier, effluent from the clarifier goes to the polishing pond, final effluent goes to the contact chamber, is either discharged by gravity or pumped to Outfall 001. The original effluent pipe has been clogged significantly (with capacity of less than 20 gallons/minute). When flow exceeds the capacity, effluent has to be pumped (with a portable pump) to the water intake station (using the existing water intake pipe) and then to Outfall 001 through layflat hose. It was noted that at the time of inspection both surface aerators were not operable. There were very little amount of biosolids/sludge in the aeration basin. Discharge from the stormwater pond was stopped (valve at the discharge pipe was closed) since the spill in March 2014. Upstream/downsteam monitoring at Outfall 001 has not been performed since December 2017. The flow meter attached to the effluent pump has not been calibrated annually.
