A. Overall:
The Applicant's description of the proposed Phase I facilities regarding dual facilities for essential
treatment units (i.e., Comment A.I in the Response Letter dated April 3, 2023) does not meet 15A
NCAC 02U .0402(c). The submitted Engineering Calculations show the effluent from the first
textile filter unit does not meet the monthly average five-day biochemical oxygen demand (BOD5)
of 10 mg/L before the polishing filter unit. If either the first textile filter unit or the polishing filter
unit was to go offline for maintenance or repairs in this configuration, Type 1 reclaimed water
effluent standards would not be met per 15A NCAC 02U .0301(b).
Please either revise the application package:
a. To show a piping configuration for the first textile filter unit that allows continued operation
while it is isolated for repairs; or
b. To install the second Phase II textile filter unit with the Phase I facilities.
Additionally, can the UV units in series operate individually if one were to go offline for
maintenance or repairs?
2. In regards to the Applicant's response to Comment A.2 in the Response Letter dated April 3, 2023,
the permitted flow is the most restrictive of the treatment capacity and the disposal capacity. For
the proposed Phase I facilities, the treatment capacity is 10,000 GPD (per the submitted
Engineering Calculations) and the disposal capacity remains unchanged at 20,000 GPD between
the existing drip and spray fields. A review of recent NDMRs shows the average monthly flow for
the existing facility is well below 10,000 GPD.
If the second Phase II textile filter unit is not installed with the Phase I facilities, the permitted flow
for this permit renewal with major modification will be 10,000 GPD. No response is required.
Maria Schutte of the Mooresville Regional Office has concerns about the location of the sampling
port, which is currently proposed on the effluent side of the polishing filter unit prior to UV
disinfection. She would prefer to see it moved to the effluent side of UV disinfection prior to
irrigation. There is a potential for fecal coliform spikes in monitoring data with the sampling port
in its current location. If the sampling port will not be moved, what will be done operationally to
remedy this?
