Mid -South received an Authorization to Construct for a 0.10 MGD WWTP on Feb. 25, 1987. The renewed permit should be issued with effluent limits for 0.10 MGD (current design flow) and 0.13 MGD (current permitted flow). The facility discharges into a zero flow stream (7Q10 and 30Q2 flow = 0 cfs) and should be required to cease discharge when an alternative becomes available. At the current time there does not appear to be any alternative to discharge.

PO Box 127 Sherrills Ford, NC 28673 Dear Mr. Weber: 03- o`t- kZ r c,E�VEII APR301991 S11PPr B�Aµftl Subject: NPDES Modification Application NCO065749 Mid -South Water Systems/Ashe. Plantation Mecklenburg County Your application for a NPDES Permit to discharge an additional 0.070 MGD (0.200 MGD total) of treated wastewater into Duck Creek from an existing wastewater treatment facility located at Ashe Plantation was received on April 25, 1989. Our Mooresville Regional Office has performed a site investigation, and the Division has completed its review of the permit application. Our review has determined that the receiving stream designated by you has no natural flow on at least seven (7) consecutive days during a ten (10) year period and at least thirty (30) consecutive days during a two (2) year period. We refer to this stream as having a zero 7Q10 and 30Q2 flow. The North Carolina Administrative Code, Section 2B .0206 (d)(2) specifically prohibits new or expanded discharges under such flow conditions. Therefore, your request for a NPDES permit is hereby denied. Several wastewater treatment and disposal alternatives may be available in order to obtain approval for this project. Locating your discharge further downstream or on a larger stream that can accept your wastewater without having to degrade water quality , utilizing a ground absorption system which is handled under the jurisdiction of the local health department, or connecting to a publicly -owned treatment works are alternatives which should be evaluated. We stand ready to discuss these alternatives with you in detail and to assist you in any way we can in selecting a suitable means of wastewater disposal. Pollution Prevention Pays P.O.
