This is a permit renewal for a domestic wastewater treatment system. Like the facility for the
Emerald Point subdivision (NC0059579), this facility is in compliance with permit limits, although
some reported values for TRC, TN, and TP seem to be excessive. P&E recommends renewal with existing
limits. Region: Please comment on appropriateness of requiring dechlorination/TRC limit for this
facility.

I'ART IV e EVALUATION AND RECOMMENDATIONS
Carolina Water Service, Inc., has requested renewal of the Queens Harbor WWTP NPDES
permit. Only one of the aeration basins is being used at this time. The facility appeared to be well
run and maintained. There were suspended solids in the effluent during this inspection.
This package plant is similar to the facilities at Boiling Springs, Cleveland County. These
package plants are notoriously difficult to operate and are easily upset. As construction continues
around Lake Wylie it is apparent that connection to CMUD may become possible. This Office
recommends that connection to a regional sewer system should be requited as soon as regional sewer
is available.
This Office recommends renewal of this permit with the condition that connection with a
regional sewer system be done as soon as practicable.
