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.
Sincerely,
Michael Myers

NOTES: On September 11, 2019 the operator contacted Delta Systems and reported an issue with
the effluent turbidity meter. 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.
Sincerely,
TJJohnson

pumps each with an influent flow meter and one aerator
• Two 31,500-gallon anoxic chambers each with two 3 hp mixers
• Two 189,000-gallon aeration basins each with two 10 hp aerators
+ Two 3I,500-gallon clarifiers each with one variable speed sludge return pump
• 1- 75,400-gallon sludge holding basin with one variable speed decanting pump
one 7.5 hp aerator
• 10,730-gallon chlorine contact chamber with two variable speed chlorine injection
pumps, 15,800-gallon mud well with two 200 GPM return pumps
• Two 90 square foot tertiary filters
• 13,800 gallon clear well with four 675 GPM backwash pumps
• Dual banks of ultraviolet modules each with 10 bulbs
• I- 6,850-gallon dechlorination chamber with two air diffusers

• The continued operation of 3.5 MG clay lined five day upset pond with a 400
GPM dual submersible pump station and audible/visual alarms and a 21.3 MG
clay lined central storage pond with dual 2,000 GPM flooded suction pumps.
The treated wastewater is then sent to spray irrigation zones which are located throughout
the property's common areas.

11. Performance
