NPDES WW Permit No. NCO032239
Onslow County
Dear Permittee:
The North Carolina Division of Water Resources conducted an inspection of the Regalwood WWTP on
12/08/2021. This inspection was conducted to verify that the facility is operating in compliance with the
conditions and limitations specified in NPDES WW Permit No. NC0032239. 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 Helen Perez with the Water
Quality Regional Operations Section in the Wilmington Regional Office at 910-796-7215 or via email at

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
A routine compliance inspection of the Regalwood WWTP was conducted on December 8, 2021. The
purpose of the evaluation was to verify that the facility is operating in compliance with the conditions
and limitations specified in Permit NC0032239. Greg Spillman, Anthony Futrell and staff were present
during the inspection.
This older 0.125-MG facility consists of an originally designed 0.065-MG contact stabilization basin
and a 0.060-MG extended aeration basin, both with clarifiers. Currently, flows averages
approximately 0.073-MG. The contact stabilization basin has been changed to operate as an
extended aeration basin. Effluent from the clarifier units flows to a polishing pond for further solids
removal and then discharges to the Northeast Creek.
A review of violations for this permit cycle shows:
10/17 daily TSS
10/19 daily Enterococci
05/20 monthly flow
06/20 monthly flow
10/20 daily BOD
11/20 frequency for BOD, Enterococci, ammonia, TP, TSS
12/20 daily BOD
02/21 daily BOD
04/21 daily, monthly BOD & daily Enterococci
A technical assistance visit was requested by Carolina Water Service staff in June of this year to
discuss issues with COD from de -chlorination influencing BOD and possibly other composite
parameters. As sugested, floats have been adjusted to allow volume to build up in the EQ during the
day providing a more consistent and continuous 24-hour flow pace, and dosing of the dechlorination
chemical has been adjusted so that TRC values produced are in the 20-35 ug/I range to reduce any
COD impact.
The current permit expires on June 30, 2022 and a renewal application is due by December 31,
2021. The facility is compliant with NPDES Permit NC0032239. Please review the comment sections
of the inspection report for more details.
