G- FIBFMD APR 1 12023 Dr. Sergei Chernikov, Environmental Engineer III North Carolina Department ❑f Environmental Quality Division of Water Resources WQ Permitting Section - NPDES 1617 Mail Service Center Raleigh, North Carolina 27699-1617 Dear Dr. Chernikov, Marine Corps Base Camp Lejeune (MCE CAMLEJ) is requesting a major modification to the National Pollutant Discharge Elimination System (NPDES) permit No. NCO063029 to incorporate two new waste streams to our Advanced Wastewater Treatment Plant (WWTP). The proposed intermittent waste stream additions will treat for Per- and Polyfluoroalkyl Substances (PFAS) and are detailed in Enclosure (1), which provides Sections F.13-F.15 of NPDES Form 2A Additional Information and system diagrams for each new system. The permit modification fee is provided as Enclosure (2). Following acceptance of this permit modification, MCB CAMLEJ will operate these systems to reduce combined perfluorooctanoic acid and perfluorooctane sulfonic acid detections to below 70 parts per trillion, or any future regulatorily established level. MCS CAMLEJ will notify NCDEQ prior to the discharge of waste from the new PFAS treatment systems to the WWTP and will provide analytical data as requested. Questions regarding this permit renewal should be forwarded to Mr. Travis Voorhees, Environmental Quality Branch, Environmental Management Division, G-F, at (910)451-9518.
