Thorpe,r,Wa er Quality Supervisor Washington Regional Office �J FROM: Alton R. Hodge / Environmental Engineer Water Quality Section SUBJECT: Non -Discharge Permit Application Resubmittal Kinnakeet Shores Dare County \ Mr. Bill Gilbert, of Bissell Triangle Associates, has resubmitted the Kinnakeet Shores project. The resubmittal has made the following changes: design flow from 0.5 MGD - to 0.05 MGD, disposal from spray bed - to rotary distributor, and no underdrain system. The rotary distributor is adjacent to an existing mobile home park with individual septic tanks as the wastewater treatment system. The proposed buffers are consistent with the regulations. However, I asked Ed Andrews, of Russnow, Kane, and Andrews, the consulting hydrogeologists, to address the septic tanks in the mobile home parks as they relate to groundwater moun-d under the rotary distributor. He did so by letter dated October 30, 1987. It is recommended that the permit be granted with the following special conditions: 1. Chlorine shall be maintained in the chlorinator at all times such that a minimum of 0.5 mg/1 of chlorine residual is maintained after 30 minutes of contact time. 2. The operation of the treatment plant shall be monitored as fo'1 lows : Parameter Sample Location Sampling Frequency Flow Influent or effluent Recording Continuous BODS Influent & effluent Composite *2/Monthly'.',", Suspended Solids Influent & effluent Composite *2/Monthly Fecal Coliform Effluent Grab *2/Monthly Residual Chlorine Effluent Grab Daily *2/monthly sampling frequency only during the months of May through September. During the remainder of the year, this parameter shall be monitored mont}ily. Gil Vi-n7.ani November 25, 1987 Page 2 3. Monitoring reports including the above information shall be submitted monthly to Regional Supervisor, Washington Regional Office, P. 0. Box 1507, Washington, North Carolina, 27889. Each report shall be due within 30 days following the end of the reporting period. 4. The length of time that the standby power unit is operated shall be monitored and reported in the monthly reports described above. The length of time that the standby power is operated due to power outage shall be reported separately from the time that the standby power is operated for the -purpose of routine exercising. 5. The treatment facility shall be operated such that the treatment facility achieves a minimum of 90% removal of BODS and Total Suspended Solids and shall meet a monthly average effluent limit of 20 mg/l of BODS and 10 mg/1 of Total Suspended Solids. 6. All treatment units described in this permit including the flow measuring and recording device, and the automatically activated standby power generator shall remain operational at all times. In the event of the failure of any unit or the bypass or over- flow of any wastewater, the Permittee shall notify the Division of Environmental Management, Washington Regional Office, as soon as possible, but in no case later than 48 hours after the occurrence.

Due to the location and proximity of natural sinks., the discharge of 50,000 GF'D will not adversely affect the neighboring septic tank discharges. If you have any questions please tall.
