An R} Company NC Dept of Environmental Quality OCT 2 5 2019 Raleigh Regional Office Subject: NOTICE OF VIOLATION & NOTICE OF INTENT TO ENFORCE NOV-2019-PC-0658 Permit No. WQ0028552 Briar Chapel Development Reclaimed Water Generation & Irrigation System, Conjunctive Reclaimed Water Utilization, Non -Conjunctive Reclaimed Water Utilization, and Wastewater Irrigation System Chatham County Dear Mr. Bolich: OId North State Water Company appreciates the opportunity to respond to the Notice of Violation issued on September 23, 2019 by the Division of Environmental Quality. Please find enclosed our response regarding an inspection by Mr. Rick Trone from the Raleigh Regional Office. This response will provide additional information and it is our hope that this additional information is sufficient, and that the Division will decide not to pursue further action. REQUESTED RESPONSE: 1. Please verify that the information on the attached ORC assignment table is correct and submit the appropriate forms to the Water Pollution Control SOCC to update this information as needed: ■ Please find attached an updated ORC Designation List Form for William Lamm. 2. Please provide a schedule for the inspection and replacement of the odor control media at the wastewater treatment plant. ■ Carbon media was replaced on July 9, 2019 as well as the blower motor which was replaced on July 31, 2019. Based on manufacturers recommendations we have initiated an annual air monitoring program to evaluate "breakthrough" on the media. If breakthrough of the individual compound is noted, the media will be scheduled for replacement. Please explain the presence of excessive foam and turbidity in the clarifiers at the wastewater treatment plant. ■ On the morning of the visit, an electrical issue caused the RAS pump breaker to trip resulting in the loss of solids. The ORC started the RAS pump back and flow was diverted to the upset pond and retreated. The ORC started the RAS pump back up when he arrived and attempted to clean the sludge as well as he could. 4. Please explain why the chlorine feed hose was not providing chlorine to the chlorine contact chamber for disinfection ■ As you may be aware, disinfection is via UV disinfection with chlorine as a backup and used for algae control at the plant. A five foot piece of 318 inch neoprene tubing failed had to be replaced on the chlorine pump. Attached please find the closed work order confirming completion. Please ensure that the turbidity meter is operating properly and provide this office with proof the meter is functioning by submitting laboratory analyses or confirmation readings with another calibrated flow meter. ■ The turbidity meter is operating properly. Please find attached the proof of calibration for the turbidity meter performed with a calibrated flow meter by Delta Systems on September 13, 2019. 6. Please explain why the missing NDMR data have not been reported, and what the facility plans to do to ensure these violations are corrected. ■ The missing NDMR data is related to the use of a new form in October 2018 that did not allow for input of turbidity and reclaimed water production. We have contacted DEQ central office and have received an updated NDMR form and are currently submitting amended NDMRs to report this data. 7, Please provide DWR with a copy of the most recent Annual Report summarizing the performance of the wastewater treatment and utilization facility. ■ Please find the 2018 Annual Report attached. 8. PIease provide a copy of the most recent soil analyses for each irrigation field in Phase 1-B. ■ The irrigation field in Phase 1-B has not been constructed or certified. ONSWC is currently evaluating the need far this field and if not needed, we will notify the Division. 9. Please provide copies of the operator's logs for the wastewater treatment system and the reclaimed water distribution system for the period of January 1, 2018 to September 15, 2019. Please find attached the operators logs for the period of January 1, 2018 through September 15, 2019. 10. Please describe efforts that Old North State Water Company has taken to address the excessive odors coming from the wastewater treatment plant and the reclaimed water storage pond and distribution system. • The odors emaciating from the WWTP are significantly less than from similar facilities. While ONSWC understands the sensitivity, the use of the word "excessive" is not an accurate description. ONSWC has completed numerous upgrades to minimize the impact of the facility and address odors. These upgrades include: 1. Covering of the equalization basin and bar screen. 2. Scrubbing of the air generated on the equalization basin and bar screen. 3. Installation of aeration units on the reclaimed water holding ponds. 4. Installation of additional aeration units on the reclaimed water holding pond. 5. Addition of a chlorine feed on the reclaimed water system. 6. Installation of flushing valves on the reclaimed distribution system. 7. Changes to operating procedures designed to minimize odors generated. Please contact us if additional information is needed. While the violation was unfortunate, we feel that a civil penalty would not be prudent as we have acted in a responsible manner to address these issues. We hope that the Division recognizes the significant amount of resources that are devoted to this system. Therefore, we request that the Division consider these efforts when deciding on further enforcement. We are committed to full compliance with all the permits of the Briar Chapel Permit Number WQ0028552.

The meter below was calibrated for turbidity and had the recommended program and verification checks.

A technician was sent to the plant on September 13, 2019. It appears the sensor slipped into some sediment at the bottom of the effluent basin. The unit was removed from the water, cleaned with special attention to the sensor window. The unit was then put back in the water above the sediment and secured in place. At this time the unit appeared to be working properly and the technician did not see the need to calibrate it at this time. The next scheduled calibration is February 2020. If there are any questions or concerns, please contact me at the number listed below.
