TACTICAL WATER PURIFICATION SYSTEM TESTING The facility may discharge effluent from a mobile tactical water purification system (TWPS) as needed under the following conditions: • The separated treated water stream and the saline brine stream must be combined prior to discharging back to the original water source. Page 9 of 17 DocuSign Envelope ID: E8C5C154-058F-4CE6-AEED-86EE54D3F373 Permit NCO063029 • Any backwash from the reverse osmosis element and the microfiltration filter must be collected and treated at the Camp Lejeune Advanced Wastewater Treatment Plant, in accordance with the terms and conditions of this permit. • The only chemical allowed to be added to the water during TWPS testing is an antiscalant. It must be captured in the backwash waste stream. • The objective of the training exercise is to practice operating the mobile water purification unit, rather than generating potable water for actual consumption. • The chlorine injection system included with each TWPS unit will be exercised bypassing water, rather than liquid calcium hypochlorite, into the TWPS product water. • The permittee must discuss any deviations from these conditions with the Division prior to discharge. • Written notification of proposed TWPS testing must be made to the Division's Wilmington Regional Office, Surface Water Protection Section at least two weeks prior to the testing. This notification must include the location and dates scheduled for the testing. A. (8.) REACTIVATION OF DISCHARGE [G.S. 143-215.1(a)] The permittee shall notify the DWR (NPDES Complex Permitting Supervisor and Water Quality Wilmington Regional Office Supervisor), in writing, at least 30 days prior to resuming operation and discharge to Wastewater Treatment Plant from either RCRA groundwater pump and treat remediation systems identified as AS-4141 or Rapid Refueler Aggressive Fluid Vapor Recovery. Upon notification, the Permittee shall provide analytical results which confirm the combined PFOS/PFOA detections are below 70 parts per trillion (ppt) or any other Local, State or Federal regulatory established level. A. (9.) BIOCIDES [G.S. 143-215, 143-215.1] The permittee shall obtain approval from the Division prior to the use of any biocide in the cooling water discharged to this facility. Approval should be requested at least 90 days in advance of the planned use of any biocide which may be toxic to aquatic life (other than previously approved compounds). The request should be submitted to the Aquatic Toxicology Unit of the Division's Environmental Sciences Section at the following address: NC DEQ / DWR / Water Sciences Section 1621 Mail Service Center Raleigh, North Carolina 27699-1621 Consult the Aquatic Toxicology Unit for specific items that should be submitted with each request (such as Biocide Worksheet Form 101, MSDS documentation, etc.). Concentrations of chromium, copper or zinc added to biocides shall not exceed applicable water quality standards (or action levels) in the receiving stream. These concentrations should be calculated using the Biocide Worksheet Form 101 with the Supplemental Metals Analysis Worksheet. A. (10.)
