There are just a couple of potentially minor items that must be addressed before I am able to approve the modification(s). Please address the following items: 1. The BUA table provided on plan sheets EX-1.1 through EX-1.5 for the SW8 970847 modification was not updated and is inconsistent with the rest of the submitted documentation. For example, this table still indicates that the total existing BUA is 377,233 square feet, however, it was previously confirmed that the total existing BUA per the permit is 307,537 square feet.

The pre/post development BUA and drainage area was not quantified for the redevelopment area proposed within SW8 970847, as requested in Item 3.i. of the November 8, 2021 letter. The response received on November 12, 2021 indicates that "The reason no changes were shown is that no changes are being made. The area is proposed to be milled and overlaid...." Section IV.10 of the application, however, provides BUA information for both "Existing" and proposed "Parking" BUA, 52,058 square feet and 10,000 square feet, respectively, for a total of 62,058 square feet.

Please note, the approval of all three projects (SW8 970219, SW8 970847 and SW8 210708) are contingent on each other and cannot be approved until the above information is provided. Please also note, I will be on vacation starting December 17, 2021. Since the above items are relatively minor, I have begun drafting the permits and can likely issue them if the requested information is received prior to me leaving for vacation.

While the 1.0" design storm can be used to calculate the runoff from the previously approved built -upon area (BUA), any increase in BUA must be accounted for at the 1.5" design storm. In this case, permit no. SW8 970847 approved a total of 307,537 square feet of BUA, which can be accounted for using the 1.0" design storm. Section IV.10 of the application indicates that 383,995 square feet of BUA is now proposed for this project. The increase of 76,458 square feet would need to be accounted for at the 1.5" design storm. Please revise the calculations to ensure the correct design storm is being used to calculate the minimum required storage volume and ensure it is represented consistently throughout the entire application package. RE: Our understanding of previous discussions that were had with Christine Hall had indicated that modifications of the existing permits should be done under the original permit guidelines. That the permits didn't need to be updated to meet new requirements since they were designed and developed under a previous and existing permit. However, updated calculations are provided in this resubmission package to indicate the additional required storage resulting from the additional area being analyzed at 1.5" rather than 1.0".

DEHNR Water Quality Section final review comments dated 7 Nov 97 on the Stormwater Management permit application for the referenced, DEHNR Stormwater Project No. SW8 970847 The following changes have been made to the stormwater management plan as the result of a meeting held at the NCDENR Division of Water Quality Wilmington office on 19 Nov 97 with Ms. Linda Lewis: (l. The forebay has been enlarged to exceed the minimum 20% of the total first 1" volume of runoff as follows; i Total first 1" runoff volume = 31,468 cu. ft. (from original calculations) Revised forebay volume = 8,000 cu. ft. % of first 1" runoff volume=_(8,000/31,468)_X 100%= 25% _ 2. The 0.9 acre drainage area along the Access Rd. adjacent to the van pad will be allowed to drain into the existing canal with the inclusion of the 2.2 acres from the existing off -site parking lot into the pond. This arrangement is described in the previously submitted Stormwater Management Pond paragraph of the Narrative accompanying the calculations. There is no change to the plans. 3. Future development must include considerations for stormwater management for the southern portion of the access road as well as the remaining tract. The drainage system shown on sheet C4 is reconfigured to accommodate this requirement. 4. Two copies each of sheets C4, C7, and C 13 are attached with a copy of this memo and forwarded to Ms. Lewis at the NCDENR Division of Water Quality office in Wilmington. It is our understanding that the stormwater management plans will be approved upon successful review of this submittal. PLEASE REFER TO ORIGINALLY APPROVED APPLICATION.

The state has given us permission to plant shrubs along the pond slopes to reduce line of sight for the geese. In order for us to do this we had to submit 0&M addendums, which I dropped off to you this afternoon. The state has already approved the 0&Ms and has requested that Carl sign the documents for their files.

SW8 960509, SW8 970847, SW8 970927, SW8 080653 and SW8 090117 Onslow County Dear Mr. Baker: Dee Freeman Secretary The Division of Water Quality (DWQ) received a request from Lauren Acosta, Camp Lejeune Environmental Office, to assist in a study to reduce Bird/Wildlife Aircraft Strike Hazard (BASH) incidents at the Air Station. DWQ was asked to consider allowing the use of low profile, low maintenance shrubs on the aquatic shelf of selected permitted wet detention ponds that have high geese usage. The study approach proposes to decrease geese usage of the ponds by planting shrubbery that will create cover for geese predators and steepen the takeoff/landing angles for the geese. Basically the theory states that if the geese have to walk through high vegetation, where predators could be hiding, to access a nearby feeding area, or if the angle of takeoff and landing is too steep, then the geese may not find the pond a favorable habitat. The study calls for the installation of four shrub species on the outer edge of the aquatic shelf, Baccharis hamilifolia, Itea virginica, Lindera benzoin, and Ilex glabra. According to the documentation submitted with the request, these species were chosen for the following reasons 1. The height should not exceed 4-5 feet above the top of the pond bank; 2. The fruits are not a significant food source for geese; 3. They can adapt to wet or dry growing conditions and low soil nutrients; and, 4. They are available for a December 2011 /January 2012 planting period.

Baker, Deputy Public Works Officer USMCB Camp Lejeune December 19, 2011 Page 2 The Division is approving your request as proposed, subject to the following conditions: 1. Use as many non -deciduous shrub species as possible to avoid adding additional floating debris to the pond. 2. Provide the Division with a copy of the final report of the study's conclusions. 3. Upon receipt of this approval letter send signed and dated copies of each "BASH Mitigation — Stormwater Plantings Operation and Maintenance Agreement Addendum" to DWQ. This agreement will be placed into the file for each Stormwater project listed above and will become an enforceable part of that permit. 4. Notify the Division immediately of any compliance issues or nuisance maintenance conditions that arise as a result of the use of these shrubs. 5. If the Division concludes that the use of the shrubbery creates a compliance issue or leads to nuisance maintenance conditions, then the Division may require that the shrubs be removed and the pond be restored to its original design condition.
