ICIA Environmental Quality December 02, 2019 Chris Grimes, Utilities Operations Manager Town of Fuyuay-Varina 401 Honeycutt Road Fuyuay-Varina, NC 27526 Subject: Compliance Evaluation Inspection Terrible Creek WWTP NPDES Permit Number NCO066516 Wake County Dear Mr. Grimes: Mitch Hayes of the Raleigh Regional Office conducted the subject inspection on November 26, 20I9. The assistance of Adam Stephenson, Operator in Responsible Charge (ORC), and yourself, back-up ORC, with this inspection was greatly appreciated. Below is a list of findings developed from the inspection and review of the permit. 1. The subject NPDES permit was issued January 01, 2016 and expired April 30, 20I9. The permit is currently under review. Please continue to operate under the last issued permit until a new permit is issued. 2. The 3.0 MGD Class WW-3 WWTP consists of the following units: three (3) EQ basins; influent pump station with six (6) pumps; mechanical coarse bar screens; 1l4- inch mechanical bar screens; grit cyclone and classifier; two (2) five -stage conventional BNR basins; two (2) secondary clarifiers; RAS pump station; two (2) Leopold Ultrascreen disk style filtration units; two (2) UV disinfection channels, each with two service and one redundant bank of UV lamps; ultrasonic effluent flow meter; cascade aeration; WAS pump station; one (1) aerated sludge holding tank; gravity belt thickeners; two (2) three belt filter presses; truck loading facility for off -site composting. 3. At the time of inspection, all units were in operation. The three EQ basins were empty. All six influent pumps were in operation. Screenings and grit are conveyed to a dumpster to be landfilled. The color of the influent in the BNR reaeration zone appeared to be chocolate brown. There was no foaming. Caustic is being fed to reduce total phosphorus. Weirs in both secondary clarifiers were clean with no obstruction. Effluent flowing off the weirs appeared clear. Sludge blanket depths in both secondary clarifiers were one foot. Both UV channels were in operation. Effluent flowing in the UV channels and at the outfall appeared clear with no foaming. Gravity belt thickeners and the belt filter presses were in operation. Sludge was being dewatered and loaded onto a tractor trailer truck. �L3 ( ;: 4 � s N::rth Caro ina Department cf Environmental Quality Div son of Water Resources Raleigh Reg onal office 3800 Barrett Drive 1628 Nla I Service Center I Raleigh, North Carolina 27699.1628 4. Discharge Monitoring Reports for the review period February 2018 through September 2019 for compliance with pen -nit limits and monitoring requirements. The following are noted: Enforcement case MV-2018-0013 for Quarterly monitoring violations for Total Zinc and Total Copper for March 2018. This case is still open. Enforcement case LV-2018- 0211 for ammonia nitrogen monthly average violation for April 2018. This case is closed. Enforcement case LV-2018-0236 for monthly and weekly ammonia nitrogen violations for May 2018. This case is closed. Enforcement case LV-2018-0299 for BOD weekly violation, exceeding permit flow limit, and exceeding weekly ammonia nitrogen limit for June 2018. This case is still open. 5. Commercial lab results, chain of custody records, and bench sheets were compared with data submitted on the Discharge Monitoring Report (DMR) for the month of September 2019. No discrepancies were noted. I would like to thank you and Adam Stephenson for you time and assistance with this inspection.
