For ease of reference we've included your original comment in gray italic. 1. The certification of Compliance issued on July 14, 2014 limits the amount of impervious area to 122,870 square feet with no allocation of future impervious area. Any increase over this approved amount is considered a major modification to the permit and requires the additional impervious area to be considered and permitted under the current rules. Please revise the application documents as necessary to document the change in the design storm for the additional impervious area. If extra volume is available in the wet detention pond, please consider adding a future impervious allocation, which will make future small increases in impervious area like this an easier permitting process. I have revised the calculations using the current BMP requirements for the new impervious area that will be added to the permit, additionally because the existing BMP has more volume than required for the existing and the additional boiler building impervious, I have added the impervious area that uses the remaining volume as future impervious area on the application. The revised calculations and the revised page 3 of the application are attached for your review. 2. Please provide calculations for how a drawdown time of 4.78 days was determined. According to the original calculations dated August 1996, in two days, the pond stage would be 4.78 feet. ECEIVE AUG 2 2 2014 BY: f The 4.78 days was reported in error, I have revised the drawdown calculations using the new treatment volume and the existing discharge structure's original design. The calculated treatment volume draws down in 2.5 days. The calculations are attached for your review.

Skvarla, III Secretary The Wilmington Regional Office received and accepted a modified State Stormwater Management Permit Application for the Electronics Communications Maintenance Building FC134 on May 1, 2014. A preliminary in- depth review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: The permit renewed and re -issued on July 14, 2014 limits the amount of impervious area to 122,870 square feet with no allocation of future impervious area. Any increase over this approved amount is considered a major modification to the permit and requires the additional impervious area to be considered and permitted under the current rules. Please revise the application documents as necessary to document the change in the design storm. If extra surface area and volume is available in the wet detention pond, please consider adding a future impervious allocation, which will make future small increases in impervious area like this an easier permitting process. 2. Please provide calculations for how a drawdown time of 4.78 days was determined. According to the original calculations dated August 1996, in two days, the pond stage would be 4.78 feet. Please remember that a change to one number may have a domino effect on other numbers. Please check all plans, calculations and forms to ensure that the numbers are consistent throughout. 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 August 22, 2014, or the application will be returned as incomplete. The return of a project will necessitate resubmission of all required items, including the application fee. If you need additional time to submit the information, please mail, email or fax your request for a time extension to the Division at the address and fax number at the bottom of this letter. The request must indicate the date by which you expect to submit the required information. The Division is allowed 90 days from the receipt of a completed application to issue the permit. 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.

In order to decentralize the existing steam system, new localized boilers will be added at locations either in or near each of the existing buildings. Any additional impervious surface added to areas that are outside an existing permitted area will be done with an NOI permit and will be provided under separate cover. This permit modification is for the construction of a proposed boiler building adjacent to FC134 located within French Creek (FC) areas of Camp Lejeun. FC134 is within an area that is covered by permit SW8960815, Electronic Communication Maintenance Building 2 although it was originally permitted with SW8901010. The permit was subsequently permitted with another project to add Concrete Paving and Loading Ramps and became SW8960815. This application also requests a name change from "Build 2" to "Facility FC134". Stormwater drains within the White Oak River Basin and outfalls Cogdels Creek, stream index # 19-23, SC; NSW waters. There doesn't appear to be any defined permitted project boundary and the new building will discharge to the existing wet detention pond constructed with SW8960815. This application will also be used to define the project boundary for the permit. This building will be constructed in a grass area and will result in 269 square feet of new BUA. The existing permit is a high density permit with a wet detention pond with no future BUA allocated. Review of the design calculations shows the wet pond has adequate capacity for this minor increase in BUA, as there is no change in the percent impervious of 60%. Attached is the permit modification, the revised O&M agreement and wet detention pond supplemental form.
