C-0706 May 26, 2020 DEMLR - Stormwater Program Department of Environmental Quality 1612 Mail Service Center Raleigh, NC 27699-1612 Re: NCG020000 Notice of Intent - General Permit Application, French Creek Borrow Pit Reclamation, Permit #67-43, Marine Corps Base Camp Lejeune, NC Gentlemen: The base is in the process of reclaiming the above -referenced borrow pit which has ceased all operations. It will be necessary to dewater the borrow pit in order to excavate further the limited areas that will have insufficient water depth. The dewatering operations would only continue long enough to accomplish the work in these areas. Any excavated materials will remain on site to grade the required slopes. The French Creek borrow pit operated for over 20 years and conducted dewatering operations. The dewatering of the borrow pit discharged to the adjoining closed and reclaimed borrow pit to the east, where that water then discharged to Cowhead Creek. The current plan is to discharge the French Creek borrow pit in the same manner. The same contractor who operated the French Creek mine dewatering operation previously will be conducting the dewatering operations this time as well. The French Creek borrow pit exists at groundwater elevation with no significant off -site flow coming in. The area around the borrow pit is all natural with no type of operations in the area. The anticipated water level lowering is four feet in order to accomplish the work. The wetland areas to the south along Cowhead Creek area are not anticipated to be impacted due to the limited depth of groundwater lowering and geographical separation. In addition, the dewatering discharge will be running along these same wetland areas as a part of Cowhead Creek. Due to the limited groundwater drawdown, no other groundwater impacts are anticipated at the adjoining base areas. Should you have any questions regarding this project, please do not hesitate to give me a call.

The modification is to allow the temporary stockpiling of off -site generated soil material from construction sites within the existing permit boundary for the entire life of the permit as indicated on the 8 1/2 x 11 mine map and in the supplemental information both received by the Land Quality Section on August 16, 2012. A copy of the modified permit is enclosed. The conditions in the modified permit were based primarily upon the initial application. Modifications were made as indicated by the modification request and as required to insure compliance with The Mining Act of 1971. The expiration date, mine name and permit number shall remain the same as before the modification.
