A. Overall:
1. The 8-inch effluent force main on parcel 747-13.75 containing the storage lagoon and spray fields
that are associated with this permit shall be permitted in this application rather than the
Summerhouse WWTP (Permit No. WQ0029945) because this modification is adding flow and a
new source to this facility. A response to this item is not needed.
2. Upon reviewing monitoring reports for this facility, it was noted that the Holly Ridge WWTF had
an average daily flow (ADF) of 214,876 gallons per day (GPD) in 2023, which exceed 90% of the
224,673 GPD permitted capacity for the disposal system. As this application is adding a new source
