Land disturbance associated with the improvements will be approximately 17 acres. The owner is the United States Marine Corps. There are no wetlands located within the area of the development. Stormwater from the site will drain to SC;NSW waters located in the White Oak River Basin (Index # 19-16-4 .5). The project will be a high density utilizing a wet basin designed for 90% TSS removal to treat stormwater from the BEQ, parking lot, road and basketball courts. Proposed impervious for the site is 36%. Runoff from the buildings will discharge into a rainwater harvesting system and the overflow from the system will be directed into the wet basin. The project will have direct access onto Hoover Road and Wilson Drive. Water and sewer will be provided by the MCB.

I've noted below our response or actions regarding your comments for the referenced project. Enclosed please find the following items. Items: - one (1) copy of the revised Stormwater Management Calculations - two (2) copies of sheets C-130, C-505,Project Limits - revised page 3 of stormwater application - revised wet basin supplement I. changed SA/DA on calculations. This changed numbers that are located on sheet C-505 and the wetbasin supplement both of which were revised and included in this submittal. 2. added typical cross section to Project Limit Map. 3. I've added a 115 sf section of sidewalk near the intersection of Company St. B and Wilson Drive so when the future jogging trail is installed it doesn't require a modification to this permit to account for the sidewalk radius to make the connection. This addition caused numbers to change on C-505, application, calculations, and supplement. All which are enclosed. Graphically sheet C-130 changed to show the addition of the sidewalk. Please call if you have any questions.

A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: 1. Please review the SA/DA ratio used for the design of the wet detention pond. The SA/DA numbers used in the calculations are associated with an average depth of 4 ft, not the 3.5 ft that this pond has been designed for. 2. Please add a road cross-section detail to the plans. 3. Due to the minor nature of these comments, the express additional information fee has been waived for this request for additional information. 4. Please keep in mind that changing one number may change other numbers and require the calculations, supplements, and other supporting documentation to be updated. Verify all numbers are correct to ensure consistency in the application documents. Please note that this request for additional information is in response to a preliminary review. The requested information should be received in this Office prior to January 26, 2012, or the application will be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including the application fee. If you need additional time to submit the information, please email or fax your request for a time extension to the Division at the address and fax number at the bottom of this letter. Please note that a second significant request for additional information may result in the return of the project. If the project is returned, you will need to reschedule the project through the Express coordinator for the next available review date, and resubmit all of the required Items, including the application fee. The construction of any impervious surfaces, other than a construction entrance under an approved Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject to enforcement action pursuant to NCGS 143-215.6A.

Land disturbance associated with the improvements will be approximately 17 acres. The owner is the United States Marine Corps. There are no wetlands located within the area of the development. Stormwater from the site will drain to SC;NSW waters located in the White Oak River Basin (Index # 19-16-4 .5). The project will be a hybrid high density utilizing a wet basin to treat stormwater from the BEQ, parking lot and basketball courts. The jogging trail will set aside a project limit that will limit the impervious percentage to less than or equal to 24% and utilize sheet flow for treatment. Proposed impervious for the site is 36%. Runoff from the buildings will use splash blocks to direct the discharge into the collection system. The project will have direct access onto Hoover Road and Wilson Drive. Water and sewer will be provided by the MCB.

THIS PLAN TO BE UTILIZED AND REVIEWED ONLY IN CONJUNCTION WITH THE WRITTEN NARRATIVE, WHICH IS AN INTEGRAL PART OF THIS EROSION AND SEDIMENT CONTROL PLAN. 3. ALL SLOPES SHALL BE 3:1 OR FLATTER. 4. ALL ROOF DRAINS TO BE DIRECTED TO STORM DRAINAGE SYSTEM. 5. NO WETLANDS EXIST ON SITE. 6. SITE IS LOCATED ON MONTFORD LANDING ROAD AT CAMP LEJEUNE. 7. ANY BORROW MATERIAL REQUIRED WILL BE TAKEN FROM ANOTHER APPROVED SITE ON USMC BASE, CAMP LEJEUNE. ANY SURPLUS CUT MATERIAL WILL BE DISPOSED OF AT AN APPROVED SITE ON THE USMC BASE, CAMP LEJEUNE. 8. SWALES TO LINED WITH EXCELSIOR MATTING OR EQUIVALENT 1, 3, 6, 7, 8, 9, 10, 12, 14, 15, TD1, TD 2 2 CONSTRUCTION SCHEDULE- 1. Obtain approval of Plan and any necessary permits, and hold a pre -construction conference prior to commencing any work. 2. Flag work limits and stake -out roads and storm drainage structures for preliminary grading. 3. Install Gravel Construction Entrances. 4. Install sediment basins A & B, swales 12 &14, temp. div 1 & 2, skimmers and silt fencing as shown on plan prior to clearing and grubbing site. 5. Construct grass lined channels, and any other sediment control practices shown, prior to rough grading roadways, site and stockpiling topsoil as necessary. 6. Install utilities in roadway/parking lot, establish final grades and stabilize road/parking lot with stone base course. 7. Final grade, install non -municipal utilities as needed, and vegetatively stabilize areas where building construction is not imminent. 8. All erosion and sediment control Practices are to be inspected weekly and after any rainfall, and repaired as necessary. 9. Upon completion of construction, the roadway/parking lot is to be paved, and all areas permanently vegetatively stabilized with centipede sod. After site stabilization, Temporary measures are to be removed. 0 MAINTENANCE PLAN - 1. All meas rest be ins ,ected eekl and after any rainfall event anNneec�ed rep irs man rn ediately. 2. Sediment Basin to be cleaned out when the level of sediment accumulates to elevations listed on pond detail sheets. 3. Sediment to be removed from swales when they are approximately 50% filled or sediment level is with 1' of top of ditch bank. 4. Sediment to be removed from behind any Silt Fence and inlet protection devices when it becomes 0.5' deep. Fencing and inlet protection to be repaired as needed to maintain a barrier. 5. All sodded areas to be watered as needed to establish growth. Dead sod should be removed and new sod installed as needed. 6. Construction entrance to be maintained in such a manner as to prevent mud or sediment from leaving the construction site. Periodic topdressing with 2-inch stone may be required. Inspect after each rainfall and immediately remove all ON ctionable materials spilled, washed, or tracked onto public roadways. VEGETATIVE PLAN - 1. Permanent vegetation to be established in accordance with "North Carolina Erosion and Sediment Control Planning and Design Manual", Section 6.11, latest version. See Sheet C-508. 5 PLANNED EROSION AND SEDIMENT CONTROL PRACTICES - CE 1. TEMPORARY GRAVEL CONSTRUCTION ENTRANCE Practice 6.06 Shall be installed at the entrances to the project from an existing roadway. Drainage should be away from the road and erosion will be controlled with downstream practices. During wet weather it may be necessary to wash truck tires at these locations. 2. LAND GRADING Practice 6.02 Grading should be limited to areas as shown on the Plans. Cut and fill slopes shall be 3:1 or flatter except where specifically indicated. Care shall be taken during land grading activities not to damage existing trees that are identified as "to be preserved". SF 3. SEDIMENT FENCE Practice 6.62 Sediment fencing should be installed as shown on the Plan, to delineate and protect wetlands and specified areas, and around any temporary stockpile areas as necessary to prevent any graded interior areas from eroding onto adjacent lands or roadway, or into inlets, or as directed by Engineer or NCDENR/LQS personnel. GC 4. GRASS -LINED CHANNELS Practice 6.30 All overflow swales to be graded to design configuration, lined with centipede sod, to collect and convey site water as shown on Plan. After final project stabilization, swales to be re -graded, cleaned of siltation and lined with centipede sod to establish original design contours for stormwater conveyance. OP 5. OUTLET STABILIZATION Practice 6.41 Riprap aprons will be located at the downstream end of all discharge pipes to prevent scour. 6. CONSTRUCTION ROAD STABILIZATION Practice 6.80 Upon reaching final grade and after utilities have been installed, roadway/parking areas are to be stabilized by placing sub -base course of approved 4" mad stone or 6" ABC, as shown in the typical street cross-section detail on the Plan, to reduce erosion and dust during the remainder of building construction. SB 7. SEDIMENT BASIN Practice 6.61 The Sediment Basin is to be constructed first (see Construction Schedule) and is the primary Practice to prevent sediment from leaving the site. Detailed design and spillway configurations are specified in the detail sheet. SK 8. SKIMMER Practice 6.64 A sedimentation basin dewatering control device that withdraws water from the basins water surface, thus removing the highest quality water for delivery to the uncontrolled environment. IP 9. INLET PROTECTION Practice 6.51 A temporary measure of wire -mesh hardware cloth around steel posts supporting washed stone placed around the opening of a drop inlet. TD 10. TEMPORARY DIVERSIONS Practice 6.20 A temporary ridge or excavated channel or combination ridge and channel constructed across sloping land on a pre- determined grade to protect work areas from upslope runoff and to divert sediment -laden water to appropriate traps or stable outlets. ST 11. TEMPORARY SEDIMENT TRAP Practice 6.60 Sediment traps are to be installed as indicated on plan at the downstream end of swales as shown. Tp 12. TREE PROTECTION Practice 6.05 Restrict access to TPZ with tall, bright, protective fencing on areas indicated on plan.
