however, it is unknown as to whether or not capacity exists in the municipal
collection system (see Part IV below).
C. Subsurface: Insufficient area, poor topography.
PART IV - EVALUATION AND RECOMMENDATIONS
Carolina Water Services Inc. requests the renewal of the NPDES permit for the
Saddlewood Subdivision WWTP. Changes in the WWTP components since the permit was last
reissued include the addition of dechlorination facilities. There have been no changes to the
permit since the last renewal.
Considering the low flow of the receiving stream, this facility has been targeted by the
Division for elimination since the early 90's. The permittee contends that with the small number
of homes (12) connected to this facility, that the capital cost to connect to the nearby sewer line is
prohibitive. The Division should encourage the permittee to utilize alternative methods of
funding (grants, etc.,) to augment the capital costs required to connect this WWTP to the nearby
collection system during the term of this permit renewal.
Pending a final technical review by the NPDES Unit, it is recommended that the permit
be renewed as requested.
