Re: Woodlake Country Club WWTP;NPDES Permit NC0061719
Moore County
Dear Mr.Hennessy:
In May 2018, Aqua North Carolina, Inc. (ANC) completed upgrades to the Woodlake Country Club
WWTP.ANC is formally requesting a minor permit modification to update the list of facility components
contained in the permit.The changes requested are listed in bold below.In addition,Ultraviolet Disinfection
(UV)was installed and is operational. Since recent changes to the disinfection rule no longer require that
UV facilities monitor for Total Residual Chlorine (TRC)unless a chlorine derivative is being utilized for
disinfection,we formally request that this requirement to monitor for TRC be made optional.
In addition to the facility upgrades,ANC has reviewed the existing permit and is requesting that monitoring
requirements be updated to reflect existing operations and recent compliance history. Per the permit cover
letter dated July 11, 2011, North Carolina Department of Environment and Natural Resources increased
fecal coliform and TRC monitoring requirements due to a poor compliance history prior to permit issuance.
Since that date, the compliance record at Woodlake has significantly improved and ANC has performed
significant upgrades at the facility. ANC requests that the monitoring requirements be reduced to reflect a
compliant Grade II WWTP and reduce fecal coliform monitoring to lx/week per the requirement. ANC
further requests that TRC be reduced unless a chlorine derivative is utilized, and the requirement would be
lx/week. Furthermore, it was noted that ANC is required to monitor for fluoride due to the discharge of
Water Treatment Plant residuals generated at ANC facilities. ANC does not feed fluoride at any water
treatment plants within North Carolina;therefore,we request that this monitoring requirement be removed
to reflect this requirement.
List of facility components that require updating:
- Manual bar screen
- Extended aeration system
- Secondary clarification
- Ultra-violet Disinfection
- Chlorination
- De-chlorination
- Post-aeration
- Aerobic sludge digester
