REGAN secretary TRACY DAVIS Director The Wilmington Regional Office received a complete, State Stormwater Management Permit Application for the subject project on July 31, 2017. Staff review of the plans and specifications has determined that the project, as proposed, will comply with the Stormwater Regulations set forth in Title 15A NCAC 211.1000 effective January 1, 2017. We are forwarding modified Permit No. SW8 140906 dated August 1, 2017, for the construction, operation and maintenance of the stormwater control measures (SCMs), built -upon areas, as well as the stormwater collection system and/or vegetated conveyance system associated with the subject project. Please replace the previously approved plan sheets with the attached modified and approved versions. This permit shall be effective from the date of issuance until October 14, 2022 and shall be subject to the conditions and limitations as specified therein, and does not supersede any other agency permit that may be required. Please pay special attention to the permit conditions regarding the operation and maintenance of the SCMs, stormwater collection system, and/or vegetated conveyances; the limitation of built -upon area; modification of the project; the procedures for changing ownership of and/or transferring the permit; and the need to renew the permit. Please also pay attention to the permit conditions that requires the recordation of deed restrictions and protective covenants, easements, and the maintenance agreement, which must all be provided along with certification upon completion of the project. Failure to comply with these requirements will result in future compliance problems. The following modifications are included and covered by this permit: 1. October 14, 2014 Permit: This permit covered redevelopment of a portion of the 40.856ac project area. It permitted one infiltration basin. 2. August 1, 2017 Permit: a. Summary: Circumstances have required that the 2014 design be reconfigured. The modified permit will redevelop the area previously -permitted in 2014 and it will redevelop additional area, but the project area will remain 40.856ac. The project uses two sand filters for stormwater treatment. The two sand filters as well as additional area are located inside the drainage area for a dry pond. The dry pond does not receive impervious area treatment credit because it is not a primary SCM per 15A NCAC 02H .1002(46). It provides peak flow detention as required by 15A NCAC 02H .1003(5).

Redevelopment: This project meets the two redevelopment requirements: ! i. Net Increase in Impervious Area is Treated: As summarized in Section I(1) and in Table 1 of Attachment B, the project treats the net increase in impervious area as required by 15A NCAC 02H .1003(3)(d). ii. Equal or Better Stormwater Control: In the 1988 pre-existing condition, stormwater was conveyed offsite via a series of pipes and channels without treatment. The system to be constructed collects a significant portion of that water for treatment. Other areas have also been disconnected so that water from impervious surfaces sheet flows over vegetated areas. If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to request an adjudicatory hearing by filing a written petition with the Office of Administrative Hearings (OAH). The written petition must conform to Chapter 150B of the North Carolina General Statutes and must be filed with the OAH within thirty (30) days of receipt of this permit.

The project also contains a dry pond which is permitted as a secondary SCM, which is for hydraulic benefits and not total suspended solids removal per.1002(46) and .1003(5). This permit is issued in compliance with the provisions of Title 15A NCAC 2H .1000 effective January 1, 2017 (the "stormwater rules") and the approved stormwater management plans, application, supplement(s), specifications, and other supporting data (the "approved plans and specifications") as attached and/or on file with and approved by the Division of Energy, Mineral and Land Resources (the "Division" or "DEMLR") and considered an enforceable part of this permit. This permit shall be effective from the date of issuance until October 14, 2022 and shall be subject to the following specified conditions and limitations: I. DESIGN STANDARDS This permit is effective only with respect to the management and volume of stormwater described in the approved plans and specifications. The maximum amount of built -upon area (BUA) allowed for the entire project is summarized in Attachment B, Tables 1 and 2. The total allocated impervious area is 267,530 square feet to be constructed on the site. The dry pond does not receive impervious area treatment credit because it is not a primary SCM per 15A NCAC 02H .1002(46). The dry pond provides peak flow detention as required by 15A NCAC 02H .1003(5). As shown in Attachment B Table 2, the dry pond is able to accommodate an additional 54,450 square feet of future impervious area via a future permit modification (if the 54,450 square feet is also treated by a primary SCM). Therefore, the total impervious area is 321,980 square feet (which is equal to the 267,530 square feet allocated plus the potential 54,450 square feet of future impervious.) Additionally, there was 181,038sf of impervious area in place prior to 1988 as demonstrated on the permitted plans an in Attachment B Table 1. Since the total allocated impervious area for the project is 267,530sf the project must treat at least (267,530sf-181,038sf=) 86,492sf of impervious area. As shown in Attachment B Table 1, the project provides two sand filters which treat 63,162sf and 61,855sf (total=125,017sf). Therefore, this project meets the 15A NCAC 02H .1003(3)(d) requirement. Page 1 of 5 State Stormwater Management Permit No. SW8 140906 2. The drainage areas for the on -site stormwater systems will be limited to the amounts of built - upon area indicated in this permit and the approved plans and specifications. The runoff from all built -upon area within the permitted drainage areas of this project must be directed into the permitted stormwater control measures. The stormwater control measures labeled Sand Filter 1 and Sand Filter 2 have been designed using the runoff treatment method to handle the runoff from 63,162 and 61,855 square feet of built -upon area, respectively. This permit does not provide any allocation of built -upon area for future development in the drainage area of either sand filter. 3. A 50-foot wide vegetative setback must be provided and maintained adjacent to all surface waters, measured horizontally from the normal pool elevation of impounded structures, from the top of bank of each side of streams or rivers, and from the mean high waterline of tidal waters, perpendicular to the shoreline in accordance with the stormwater rules and the approved plans and specifications. 4. The stormwater control measure(s) is(are) permitted based on the design criteria presented in the sealed, signed and dated supplement and as shown in the approved plans and specifications. These stormwater control measures must be provided and maintained at the design condition_ The approved supplement is incorporated by reference into this permit. 5. The peak flow from the 10-year storm event shall not cause erosion downslope of the stormwater outlet discharge point. 6. The sand filter shall be maintained in a manner that results in a drawdown of at least two inches per hour at that sand surface. II. SCHEDULE OF COMPLIANCE The project shall be constructed in accordance with the conditions of this permit and the approved plans and specifications. 2. The on -site stormwater system shall be entirely constructed, vegetated, and operational prior to the construction of any development, per the approved plans and specifications. 3.

Tahla 1 Table 2 Pre-1988 Impervious Remaining: This is the total of the 1988 impervious area remaining within the pond area + Total Outside of the Pond Area = 15,696 + 105,718 = 121,414 sf See also Table 2 New Impervious: Total Impervious — Existing to Remain = 267,530—121,414=146,116 sf See Also Table 2 Outside of the Dry Pond DA Allocated Impervious = total project — dry pond total = 267,530—143,748=123,782 sf Existing Built Upon Area to Remain Outside of Dry Pond DA = Total untreated — proposed untreated=123,782 — 14,006 — 4,058=105,718 sf Other numbers have been filled in to help complete the story.

There will be two tables. Table 1 shows the redevelopment summary. Table 2 shows the impervious area summary. Both tables are referenced in the permit. Table 2 will also replace the table in the application, scanned below. The table in the application shows that there are 54,450sf of "future" impervious that can be allocated at a later date. Over the past few days we have determined that that "future" is to the dry pond, but not to the sand filters (as opposed to being potentially outside of the dry pond... I just wasn't sure about that originally). So, hopefully that is more clearly reflected in Table 2. The table in the application also didn't address the total 40.856ac project area, and so hopefully this table shows that that whole area is included but there is no future allocation for it. The final two numbers that I cannot figure out are: 1. 135,735sf. If there are 15,696sf of "existing remaining" to the dry pond but not to a sand filter, and there is 69,332sf of "existing remaining" outside of the dry pond, then those numbers total to 85,028sf rather than 135,736sf? 2. 131,794: If there are 143,748 total to the dry pond, and of that amount 15,696 is "existing", then the difference of those two numbers (the amount that is "new impervious") is 128,052 rather than 131,794. I have attached the Excel file as well. I just need to get these numbers to balance out. Then, the table in the application needs to be updated (just crossed out and Table 2 will become the new table in the application). And, if any data on the plans or otherwise in the package needs to be updated then we need to do that as well.

This is the "Request for Additional Information Letter", which will be handled via email in lieu of a formal letter. 1. Attached Table: Please see the attached table "2017 07 addinfo 140906" for a summary of the items needed. This table is cross-referenced with the regulations supporting the requests. This table also references the two items below. Rec-_ived, -thank you. Redevelopment [per 15A NCAC .1003(3)(d)]: This is a redevelopment project that will treat impervious area in excess of the pre-1988 amount per 15A NCAC 02H .1003(3)(d). Redevelopment projects have two requirements per 15A NCAC 02H .1002(41) and GS143-214.7: a. Requirement #1: Treat the net increase in impervious from pre-1988 i. Amount of Redevelopment: You will redevelop 181,038sf (and treat above that amount). Since the total impervious for the site is 297,515sf you will have to treat at least (297,515sf- 181,038sf=) 116,741sf of impervious area. You have two sand filters which treat 63,162sf and 61,855sf (total=125,017sf), and so you have met the .1003(3)(d) requirement. We will confirm the numbers but that appears to be the only action item here. If we need to do anything else, please advise. Please just confirm numbers. ii. Pre-1988 (1981) Map: Please provide two full-sized plans showing that there was 181,038sf of impervious area before State Stormwater permitting began in 1988. Map will be provided referencing information on the data source (digitized from aerial dated xxxxxxxx). iii. Numeric Summary: I have developed the following summary based on my review of the documents which I would like to include in the permit text. If corrections are needed, please advise. (The two tables provided in this email are provided in the Excel file containing the words "excel_BUA". We will review, verify and/or correct the numbers. It sounds like this will be in the permit language only and we don't need to place this on any plans or calculations documents. Please confirm. Please just confirm numbers.

Please show the soil type (A/B/C/D) in the calculations in support of the CN values. Appendix A of the report contains the soils information including the name of the soil and HSG classification. The CN's used are based off of the previously prepared/approved report. Except for areas that don't drain to our SCM's, the site is composed'of 2 different soils, both of which would have been represented in the previously approved Tripp documents with established CN's, which were used in our calculations. Can we use these by reference? If we don't and we have differing data sources (and we all know that there can be some variances between sources), it opens the door for calculations that show different existing conditions flows even if we do nothing, which seems to have a lot of potential to create confusion on a site with existing permitting history and these only relate to the pervious areas. Feel free to call if it may be helpful to discuss. I had not meant to make this difficult. I was really just looking to have "Type A" soils in the text of the calculations. I wasn't looking for cross- referenced sources. e. Please show the thickness of the concrete on the bottom of sand filter #2 in order to show the "bottom" elevation of the sand filter. We will add this dimension to the sections. 11 Please remember to confirm that any revised information is presented consistently throughout the application documents including calculations, supplements, narrative, and plans. Please also remember to provide two hard copies and one electronic copy of any updated documents per 15A NCAC 02H.1042(2). The requested information should be received in this Office prior to July 20, 2017, or the application will be returned as incomplete. If the project is returned and you wish to re -submit to the Express Program, you will need to reschedule the project through the Express Coordinator for the next available review date and will need to resubmit all required items at that time, including the application fee. If additional time is needed to submit the requested information, please email your extension request to the Division at the email address provided below. The request must indicate the date by which the requested information is expected to be submitted, which shall be no later than 5 business days past the original due date.

The current (2014) permit covers the entire tract that the National Guard owns, as shown by the land inside the green line "below" Control Tower Drive. (Just to clarify, I want to make sure that you understand that that whole project area will need to be re -permitted in tomorrow's application. You probably already realize that, but I just want to make sure since I don't see the project area on the plan from this morning.) I then overlaid the drainage area for the infiltration basin that was permitted in 14 2014 in diagram 2 (it isn't a perfect overlay, but you get the idea.) From the file, it looks like the area that is covered mainly by proposed sand filter #2 (the DA on the left in diagram 1) is constructed per the 2014 plans because the infiltration basin is certified. It looks like you all plan to reconfigure that area, take out the infiltration basin, and use a sand filter. The area that goes to sand filter #1 is being redeveloped from area that was not previously permitted to be redeveloped. Diagram 3 is on file from the 2014 permit. It shows the impervious area that was in place in 1981. (State Stormwater permitting began in 1988, and so the 2014 engineer submitted that to establish that he didn't have to treat all of the impervious area on the tract.) In 2014, the engineer showed that his drainage area contained impervious area that was in place well before 1988, but since it drained to the infiltration basin he treated all of the impervious area in the basin. (As I am sure you know, that is because all impervious in a drainage area has to be accounted for in order to ensure that it can all "fit" in the treatment facility). There was a small section of impervious area, as shown in Diagram 4, that he could not collect (likely because the driveway had to meet the crown of an existing road.) In retrospect, I probably should have quantified that amount of impervious in the permit. But, I did not (probably because it was so small). I have been trying to figure out the best way to document the redevelopment of this site, especially since they have been (and may continue to) make regular changes to the permit. Per .1002(41) and GS143-214.7, redevelopment must have impervious that is equal or less than the previous project and provide equal or better stormwater treatment. If the footprint of impervious is being increased, then the project falls under .1003(3)(d) and it needs a high -density permit for the net increase of impervious area. I have talked with other staff here to determine the best way to go about this. There are at least two ways, but there may be others. The most complete method would be to quantify the impervious area inside the entire project area using a pre-1988 map. Then, demonstrate that permit modifications do not exceed that amount, and that they provide equal or better treatment of impervious area. Or, the other way to do this is to compare pre-1988 with the proposed design on a drainage -area basis without addressing the entire site. We will have to work this out tomorrow.

We appreciate every effort to move up the review date. Normally we would not request this but we are receiving FY13 funds ($15M) for the construction of a new National Guard Readiness Center to be constructed on the same land as the current which was damaged by Act of Nature (Hurricane Irene 2011). Due to this being FY13 funds, they must be awarded by 30SEP2017 or they expire and the project will not happen. The timeline we are up against is the EN reviews must be completed and the 30 day period also completed prior to 17 AUG 2017 in order not to delay the already stringent timeline. This new NCNG Readiness Center will additionally be an economic asset to the Wilmington area. Again, we certainly appreciate any effort to get this review completed as soon as possible.

Hi LTC Moody: After hearing third -hand about your situation, I wanted to reach out to you directly. We make every effort to accommodate client schedules, but reviews are scheduled based on when the complete requests are received in our system and are spaced to allow the individual attention that is needed to expedite the Express Permit application reviews. We have a very limited staff available to conduct Express Reviews. In this case, after conversing via emails with Ms. Dudick, this review was already moved up once in our scheduling by more than a week by switching with the NGRC project in Jacksonville. I have now reached out to additional staff to see if they can accommodate your request, and I will let you know when our office is able to review your project. I will be in touch soon.

The review meeting is scheduled so that the reviewer is able to put their attention on that particular project immediately, but it is a balancing act between ongoing Express reviews in house already with the reviewer and when the reviewer will be able to issue the permit from the latest Express submittal. The 30 days covers the reasonable assumption that two rounds of additional information will be needed from the applicant to complete the review. The more complete the application, the faster the overall turnaround for permit issuance. I'll be in touch on Monday with a date that a reviewer will be able to meet concerning the Express Review. Let me know of any other issues.

This is the "Request for Additional Information Letter", which will be handled via email in lieu of a formal letter. 1. Attached Table: Please see the attached table "2017 07 addinfo 140906" for a summary of the items needed. This table is cross-referenced with the regulations supporting the requests. This table also references the two items below. Received, thank you. Redevelopment [per 15A NCAC .1003(3)(d)]: This is a redevelopment project that will treat impervious area in excess of the pre-1988 amount per 15A NCAC 02H .1003(3)(d). Redevelopment projects have two requirements per 15A NCAC 02H .1002(41) and GS143-214.7: a. Requirement #1: Treat the net increase in impervious from pre-1988 i. Amount of Redevelopment: You will redevelop 181,038sf (and treat above that amount). Since the total impervious for the site is 297,515sf you will have to treat at least (297,515sf- 181,038sf=)116,741sf of impervious area. You have two sand filters which treat 63,162sf and 61,855sf (total=125,017sf), and so you have met the .1003(3)(d) requirement. We will confirm the numbers but that appears to be the only action item here. If we need to do anything else, please advise. Please just confirm numbers. ii.

Can we use these by reference? If we don't and we have differing data sources (and WE all know that there can be some variances between sources), it opens the door for calculations that show different existing conditions flows even if we do nothing, which seems to have a lot of potential to create confusion on a site with existing permitting history and these only relate to the pervious areas.

Redevelopment projects have two requirements per 15A NCAC 02H .1002(41) and G5143-214.7: a. Requirement #1: Treat the net increase in impervious from pre-1988 i. Amount of Redevelopment: You will redevelop 181,038sf (and treat above that amount). Since the total impervious for the site is 297,515sf you will have to treat at least (297,515sf-181,038sf=) 116,741sf of impervious area. You have two sand filters which treat 63,162sf and 61,855sf (total=125,017sf), and so you have met the .1003(3)(d) requirement. ii.

The current (2014) permit covers the entire tract that the National Guard owns, as shown by the land inside the green line "below" Control Tower Drive. (Just to clarify, I want to make sure that you understand that that whole project area will need to be re -permitted in tomorrow's application. You probably already realize that, but I just want to make sure since I don't see the project area on the plan from this morning.) I then overlaid the drainage area for the infiltration basin that was permitted in 2014 in diagram 2 (it isn't a perfect overlay, but you get the idea.) From the file, it looks like the area that is covered mainly by proposed sand filter #2 (the DA on the left in diagram 1) is constructed per the 2014 plans because the infiltration basin is certified. It looks like you all plan to reconfigure that area, take out the infiltration basin, and use a sand filter. The area that goes to sand filter #1 is being redeveloped from area that was not previously permitted to be redeveloped. Diagram 3 is on file from the 2014 permit. It shows the impervious area that was in place in 1981. (State Stormwater permitting began in 1988, and so the 2014 engineer submitted that to establish that he didn't have to treat all of the impervious area on the tract.) In 2014, the engineer showed that his drainage area contained impervious area that was in place well before 1988, but since it drained to the infiltration basin he treated all of the impervious area in the basin. (As I am sure you know, that is because all impervious in a drainage area has to be accounted for in orderto ensure that it can all "fit" in the treatment facility). There was a small section of impervious area, as shown in Diagram 4, that he could not collect (likely because the driveway had to meet the crown of an existing road.) In retrospect, I probably should have quantified that amount of impervious in the permit. But, I did not (probably because it was so small). I have been trying to figure out the best way to document the redevelopment of this site, especially since they have been (and may continue to) make regular changes to the permit. Per .1002(41) and GS143-214.7, redevelopment must have impervious that is equal or less than the previous project and provide equal or better stormwater treatment. If the footprint of impervious is being increased, then the project falls under .1003(3)(d) and it needs a high -density permit for the net increase of impervious area. I have talked with other staff here to determine the best way to go about this. There are at least two ways, but there may be others. The most complete method would be to quantify the impervious area inside the entire project area using a pre-1988 map. Then, demonstrate that permit modifications do not exceed that amount, and that they provide equal or better treatment of impervious area. Or, the other way to do this is to compare pre-1988 with the proposed design on a drainage -area basis without addressing the entire site. We will have to work this out tomorrow. 11 Thanks, Kelly Diagram I w Diagram 2 Diagram 3 •43 ■ ■ 12 I, 130 .t -4C) Diagram 4 Carves }iaww Gw4 A4fW Waft tam NHC GiS a r -----Original Message ----- From: Gollings, Jamie E.

Hi LTC Moody: After hearing third -hand about your situation, I wanted to reach out to you directly. We make every effort to accommodate client schedules, but reviews are scheduled based on when the complete requests are received in our system and are spaced to allow the individual attention that is needed to expedite the Express Permit application reviews. We have a very limited staff available to conduct Express Reviews. In this case, after conversing via emails with Ms. Dudick, this review was already moved up once in our scheduling by more than a week by switching with the NGRC project in Jacksonville. I have now reached out to additional staff to see if they can accommodate your request, and I will let you know when our office is able to review your project. I will be in touch soon.

The quickness of the review is directly proportional to the completeness of the initial permit application packet that is brought to and discussed in the submittal meeting. The review meeting is scheduled so that the reviewer is able to put their attention on that particular project immediately, but it is a balancing act between ongoing Express reviews in house already with the reviewer and when the reviewer will be able to issue the permit from the latest Express submittal. The 30 days covers the reasonable assumption that two rounds of additional information will be needed from the applicant to complete the review. The more complete the application, the faster the overall turnaround for permit issuance. I'll be in touch on Monday with a date that a reviewer will be able to meet concerning the Express Review. Let me know of any other issues.

This is the "Request for Additional Information Letter", which will be handled via email in lieu of a formal letter. 1. Attached Table: Please see the attached table "2017 07 addinfo 140906" for a summary of the items needed. This table is cross-referenced with the regulations supporting the requests. This table also references the two items below. Received, thank you. Redevelopment [per 15A NCAC .1003(3)(d)]: This is a redevelopment project that will treat impervious area in excess of the pre-1988 amount per 15A NCAC 02H .1003(3)(d). Redevelopment projects have two requirements per 15A NCAC 02H .1002(41) and GS143-214.7: a. Requirement #1: Treat the net increase in impervious from pre-1988 f. Amount of Redevelopment: You will redevelop 181,038sf (and treat above that amount). Since the total impervious for the site is 297,515sf you will have to treat at least (297,515sf- 181,038sf=) 116,741sf of impervious area. You have two sand filters which treat 63,162sf and 61,855sf (total=125,017sf), and so you have met the .1003(3)(d) requirement. We will confirm the numbers but that appears to be the only action item here. If we need to do anything else, please advise. Please just confirm numbers. ii. Pre-1988 (1981) Map: Please provide two full-sized plans showing that there was 181,038sf of impervious area before State Stormwater permitting began in 1988. Map will be provided referencing information on the data source (digitized from aerial dated xxxxxxxx). iii. Numeric Summary: I have developed the following summary based on my review of the documents which I would like to include in the permit text. If corrections are needed, please advise. (The two tables provided in this email are provided in the Excel file containing the words "excel_BUA". We will review, verify and/or correct the numbers. It sounds like this will be in the permit language only and we don't need to place this on any plans or calculations documents. Please confirm. Please just confirm numbers.

Please show the soil type (A/B/C/D) in the calculations in support of the CN values. Appendix A of the report contains the soils information including the name of the soil and HSG classification. The CN's used are based off of the previously prepared/approved report. Except for areas that don't drain to our SCM's, the site is composed of 2 different soils, both of which would have been represented in the previously approved Tripp documents with established CN's, which were used in our calculations. Can we use these by reference? If we don't and we have differing data sources (and we all know that there can be some variances between sources), it opens the door for calculations that show different existing conditions flows even if we do nothing, which seems to have a lot of potential to create confusion on a site with existing permitting history and these only relate to the pervious areas. Feel free to call if it may be helpful to discuss. I had not meant to make this difficult. I was really just looking to have "Type A" soils in the text of the calculations. I wasn't looking for cross- referenced sources. e. Please show the thickness of the concrete on the bottom of sand filter #2 in order to show the "bottom" elevation of the sand filter. We will add this dimension to the sections. Please remember to confirm that any revised information is presented consistently throughout the application documents including calculations, supplements, narrative, and plans. Please also remember to provide two hard copies and one electronic copy of any updated documents per 15A NCAC 02H.1042(2). The requested information should be received in this Office prior to July 20, 2017, or the application will be returned as incomplete. If the project is returned and you wish to re -submit to the Express Program, you will need to reschedule the project through the Express Coordinator for the next available review date and will need to resubmit all required items at that time, including the application fee. If additional time is needed to submit the requested information, please email your extension request to the Division at the email address provided below. The request must indicate the date by which the requested information is expected to be submitted, which shall be no later than 5 business days past the original due date. 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.

The current (2014) permit covers the entire tract that the National Guard owns, as shown by the land inside the green line "below" Control Tower Drive. (Just to clarify, I want to make sure that you understand that that whole project area will need to be re -permitted in tomorrow's application. You probably already realize that, but I just want to make sure since I don't see the project area on the plan from this morning.) I then overlaid the drainage area for the infiltration basin that was permitted in 2014 in diagram 2 (it isn't a perfect overlay, but you get the idea.) From the file, it looks like the area that is covered mainly by proposed sand filter #2 (the DA on the left in diagram 1) is constructed per the 2014 plans because the infiltration basin is certified. It looks like you all plan to reconfigure that area, take out the infiltration basin, and use a sand filter. The area that goes to sand filter #1 is being redeveloped from area that was not previously permitted to be redeveloped. Diagram 3 is on file from the 2014 permit. It shows the impervious area that was in place in 1981. (State Stormwater permitting began in 1988, and so the 2014 engineer submitted that to establish that he didn't have to treat all of the impervious area on the tract.) In 2014, the engineer showed that his drainage area contained impervious area that was in place well before 1988, but since it drained to the infiltration basin he treated all of the impervious area in the basin. (As I am sure you know, that is because all impervious in a drainage area has to be accounted for in order to ensure that it can all "fit" in the treatment facility). There was a small section of impervious area, as shown in Diagram 4, that he could not collect (likely because the driveway had to meet the crown of an existing road.) In retrospect, I probably should have quantified that amount of impervious in the permit. But, I did not (probably because it was so small). I have been trying to figure out the best way to document the redevelopment of this site, especially since they have been (and may continue to) make regular changes to the permit. Per .1002(41) and GS143-214.7, redevelopment must have impervious that is equal or less than the previous project and provide equal or better stormwater treatment. If the footprint of impervious is being increased, then the project falls under .1003(3)(d) and it needs a high -density permit for the net increase of impervious area. I have talked with other staff here to determine the best way to go about this. There are at least two ways, but there may be others. The most complete method would be to quantify the impervious area inside the entire project area using a pre-1988 map. Then, demonstrate that permit modifications do not exceed that amount, and that they provide equal or better treatment of impervious area. Or, the other way to do 7 this is to compare pre-1988 with the proposed design on a drainage -area basis without addressing the entire site. We will have to work this out tomorrow.

We appreciate every effort to move up the review date. Normally we would not request this but we are receiving FY13 funds ($15M) for the construction of a new National Guard Readiness Center to be constructed on the same land as the current which was damaged by Act of Nature (Hurricane Irene 2011). Due to this being FY13 funds, they must be awarded by 30SEP2017 or they expire and the project will not happen. The timeline we are up against is the EN reviews must be completed and the 30 day period also completed prior to 17 AUG 2017 in order not to delay the already stringent timeline. This new NCNG Readiness Center will additionally be an economic asset to the Wilmington area. Again, we certainly appreciate any effort to get this review completed as soon as possible.

Hi LTC Moody: After hearing third -hand about your situation, I wanted to reach out to you directly. We make every effort to accommodate client schedules, but reviews are scheduled based on when the complete requests are received in our system and are spaced to allow the individual attention that is needed to expedite the Express Permit application reviews. We have a very limited staff available to conduct Express Reviews. In this case, after conversing via emails with Ms. Dudick, this review was already moved up once in our scheduling by more than a week by switching with the NGRC project in Jacksonville. 1 have now reached out to additional staff to see if they can accommodate your request, and I will let you know when our office is able to review your project. I will be in touch soon.

The quickness of the review is directly proportional to the completeness of the initial permit application packet that is brought to and discussed in the submittal meeting. The review meeting is scheduled so that the reviewer is able to put their attention on that particular project immediately, but it is a balancing act between ongoing Express reviews in house already with the reviewer and when the reviewer will be able to issue the permit from the Iatest.Express submittal. The 30 days covers the reasonable assumption that two rounds of additional information will be needed from the applicant to complete the review. The more complete the application, the faster the overall turnaround for permit issuance. I'll be in touch on Monday with a date that a reviewer will be able to meet concerning the Express Review. Let me know of any other issues.

This table also references the two items below. Response: Refer to the attached annotated version of the table for item -by -item responses included in the table. Redevelopment [per 15A NCAC .1003(3)(d)]: This is a redevelopment project that will treat impervious area in excess of the pre-1988 amount per 15A NCAC 02H .1003(3)(d). Redevelopment projects have two requirements per 15A NCAC 02H .1002(41) and GS143-214.7: a. Requirement #1: Treat the net increase in impervious from pre-1988 i. Amount of Redevelopment: You will redevelop 181,038sf (and treat above that amount). Since the total impervious for the site is 297,515sf you will have to treat at least (297,515sf-181,038sf=) 116,741sf of impervious area. You have two sand filters which treat 63,162sf and 61,855sf (total=125,017sf), and so you have met the .1003(3)(d) requirement. OResponse: In review of the numbers above, we believe there was a misunderstanding of w- the numbers provided. After further review, the total impervious for the proposed condition of the site has been determined to be 267,530 sf (includes 2014 additions and 2017 changes). Therefore, (267,530 sf-181,038 sf =) 86,492 sf of impervious must be treated. As stated above, this requirement is met with the 125,017 sf impervious treated by the sand filters and dry pond. ii. Pre-1988 (1981) Map: Please provide two full-sized plans showing that there was 181,038sf of impervious area before State Stormwater permitting began in 1988. ✓Ieesponse: This mapping is now including in the drawin€ III.

This is the "Request for Additional Information Letter", which will be handled via email in lieu of a formal letter. 1. Attached Table: Please see the attached table "2017 07 addinfo 140906" for a summary of the items needed. This table is cross-referenced with the regulations supporting the requests. This table also references the two items below. 2. Redevelopment [per 15A NCAC .1003(3)(d)]: This is a redevelopment projectthat will treat impervious area in excess of the pre-1988 amount per 15A NCAC 02H .1003(3)(d). Redevelopment projects have two requirements per 15A NCAC 02H .1002(41) and GS143-214.7: a. Requirement #1: Treat the net increase in impervious from pre-1988 i. Amount of Redevelopment: You will redevelop 181,038sf (and treat above that amount). Since the total impervious for the site is 297,515sf you will have to treat at least (297,515sf- 181,038sf=) 116,741sf of impervious area. You have two sand filters which treat 63,162sf and 61,855sf (total=125,017sf), and so you have met the .1003(3)(d) requirement. ii. Pre-1988 (1981) Map: Please provide two full-sized plans showing that there was 181,038sf of impervious area before State Stormwater permitting began in 1988. iii. Numeric Summary: I have developed the following summary based on my review of the documents which I would like to include in the permit text. If corrections are needed, please advise. (The two tables provided in this email are provided in the Excel file containing the words "excel BUA".

The current (2014) permit covers the entire tract that the National Guard owns, as shown by the land inside the green line "below" Control Tower Drive. (Just to clarify, I want to make sure that you understand that that whole project area will need to be re -permitted in tomorrow's application. You probably already realize that, but I just want to make sure since I don't see the project area on the plan from this morning.) I then overlaid the drainage area for the infiltration basin that was permitted in 2014 in diagram 2 (it isn't a perfect overlay, but you get the idea.) From the file, it looks like the area that is covered mainly by proposed sand filter #2 (the DA on the left in diagram 1) is constructed per the 2014 plans because the infiltration basin is certified. It looks like you all plan to reconfigure that area, take out the infiltration basin, and use a sand filter. The area that goes to sand filter #1 is being redeveloped from area that was not previously permitted to be redeveloped. Diagram 3 is on file from the 2014 permit. It shows the impervious area that was in place in 1981. (State Is Stormwater permitting began in 1988, and so the 2014 engineer submitted that to establish that he didn't have to treat all of the impervious area on the tract.) In 2014, the engineer showed that his drainage area contained impervious area that was in place well before 1988, but since it drained to the infiltration basin he treated all of the impervious area in the basin. (As I am sure you know, that is because all impervious in a drainage area has to be accounted for in order to ensure that it can all "fit" in the treatment facility). There was a small section of impervious area, as shown in Diagram 4, that he could not collect (likely because the driveway had to meet the crown of an existing road.) In retrospect, I probably should have quantified that amount of impervious in the permit. But, I did not (probably because it was so small). I have been trying to figure out the best way to document the redevelopment of this site, especially since they have been (and may continue to) make regular changes to the permit. Per .1002(41) and GS143-214.7, redevelopment must have impervious that is equal or less than the previous project and provide equal or better stormwater treatment. If the footprint of impervious is being increased, then the project falls under .1003(3)(d) and it needs a high -density permit for the net increase of impervious area. I have talked with other staff here to determine the best way to go about this. There are at least two ways, but there may be others. The most complete method would be to quantify the impervious area inside the entire project area using a pre-1988 map. Then, demonstrate that permit modifications do not exceed that amount, and that they provide equal or better treatment of impervious area. Or, the other way to do this is to compare pre-1988 with the proposed design on a drainage -area basis without addressing the entire site. We will have to work this out tomorrow.

Hi LTC Moody: After hearing third -hand about your situation, I wanted to reach out to you directly. We make every effort to accommodate client schedules, but reviews are scheduled based on when the complete requests are received in our system and are spaced to allow the individual attention that is needed to expedite the Express Permit application reviews. We have a very limited staff available to conduct Express Reviews. In this case, after conversing via emails with Ms. Dudick, this review was already moved up once in our scheduling by more than a week by switching with the NGRC project in Jacksonville. I have now reached out to additional staff to see if they can accommodate your request, and I will let you know when our office is able to review your project. I will be in touch soon.

The quickness of the review is directly proportional to the completeness of the initial permit application packet that is brought to and discussed in the submittal meeting. The review meeting is scheduled so that the reviewer is able to put their attention on that particular project immediately, but it is a balancing act between ongoing Express reviews in house already with the reviewer and when the reviewer will be able to issue the permit from the latest Express submittal. The 30 days covers the reasonable assumption that two rounds of additional information will be needed from the applicant to complete the review. The more complete the application, the faster the overall turnaround for permit issuance. I'll be in touch on Monday with a date that a reviewer will be able to meet concerning the Express Review. Let me know of any other issues.

Cc: Weaver, Cameron Subject: RE: [Non-DoD Source] RE: National Guard Readiness Center Wilmington Express Review Jamie, I overlaid the county GIS with the plan you sent me this morning in the first diagram below. The current (2014) permit covers the entire tract that the National Guard owns, as shown by the land inside the green line "below" Control Tower Drive. (Just to clarify, I want to make sure that you understand that that whole project area will need to be re -permitted in tomorrow's application. You probably already realize that, but I just want to make sure since I don't see the project area on the plan from this morning.) I then overlaid the drainage area for the infiltration basin that was permitted in 2014 in diagram 2 (it isn't a perfect overlay, but you get the idea.) From the file, it looks like the area that is covered mainly by proposed sand filter #2 (the DA on the left in diagram 1) is constructed per the 2014 plans because the infiltration basin is certified. It looks like you all plan to reconfigure that area, take out the infiltration basin, and use a sand filter. The area that goes to sand filter #1 is being redeveloped from area that was not previously permitted to be redeveloped. Diagram 3 is on file from the 2014 permit. It shows the impervious area that was in place in 1981. (State Stormwater permitting began in 1988, and so the 2014 engineer submitted that to establish that he didn't have to treat all of the impervious area on the tract.) In 2014, the engineer showed that his drainage area contained impervious area that was in place well before 1988, but since it drained to the infiltration basin he treated all of the impervious area in the basin. (As I am sure you know, that is because all impervious in a drainage area has to be accounted for in order to ensure that it can all "fit" in the treatment facility). There was a small section of impervious area, as shown in Diagram 4, that he could not collect (likely because the driveway had to meet the crown of an existing road.) In retrospect, I probably should have quantified that amount of impervious in the permit. But, I did not (probably because it was so small). I have been trying to figure out the best way to document the redevelopment of this site, especially since they have been (and may continue to) make regular changes to the permit. Per .1002(41) and GS143-214.7, redevelopment must have impervious that is equal or less than the previous project and provide equal or better stormwater treatment. If the footprint of impervious is being increased, then the project falls under .1003(3)(d) and it needs a high -density permit for the net increase of impervious area. I have talked with other staff here to determine the best way to go about this. There are at least two ways, but there may be others. The most complete method would be to quantify the impervious area inside the entire project area using a pre-1988 map. Then, demonstrate that permit modifications do not exceed that amount, and that they provide equal or better treatment of impervious area. Or, the other way to do this is to compare pre-1988 with the proposed design on a drainage -area basis without addressing the entire site. We will have to work this out tomorrow.

Hi LTC Moody: After hearing third -hand about your situation, I wanted to reach out to you directly. We make every effort to accommodate client schedules, but reviews are scheduled based on when the complete requests are received in our system and are spaced to allow the individual attention that is needed to expedite the Express Permit application reviews. We have a very limited staff available to conduct Express Reviews. In this case, after conversing via emails with Ms. Dudick, this review was already moved up once in our scheduling by more than a week by switching with the NGRC project in Jacksonville. I have now reached out to additional staff to see if they can accommodate your request, and I will let you know when our office is able to review your project. I will be in touch soon.

Redevelopment: This is a redevelopment project that will treat impervious area in excess of the pre-1988 amount per 15A NCAC 02H .1003(3)(d). Redevelopment projects have two requirements per 15A NCAC 02H .1002(41) and GS143-214.7: a. Requirement #1: Treat the net increase in impervious from pre-1988 i. Amount of Redevelopment: You will redevelop 181,038sf (and treat above that amount). Since the total impervious for the site is 297,515sf you will have to treat at least (297,515sf-181,0385f=) 116,741sf of impervious area. You have two.sand filters which treat 63,162sf and 61,855sf (total=125,017sf), and so you have met the .1003(3)(d) requirement. ii. Numeric Summary: I have developed the following summary based on my review of the documents which I would like to include in the permit text. If corrections are needed, please advise. Redevelopment Summary Impervious Area Treated: 123,017 Sand Filter #12: 63,162 Sand Filter #22: 61,855 Impervious Required to Treat': (=297,515-181,03Rsf) 116,477 July X, 2017, Impervious Total: 297,515 Pre-1988 Impervious Remaining 180,774 New Impervious 116,741 Pre-1988 Impervious Total: 181,038 1per 15A NCAC 02H .1003(3)(d) 2Neither sand filter has "future" area available. b.

The current (2014) permit covers the entire tract that the National Guard owns, as shown by the land inside the green line "below" Control Tower Drive. (Just to clarify, I want to make sure that you understand that that whole project area will need to be re -permitted in tomorrow's application. You probably already realize that, but I just want to make sure since I don't see the project area on the plan from this morning.) I then overlaid the drainage area forthe infiltration basin that was permitted in 2014 in diagram 2 (it isn't a perfect overlay, but you get the idea.) From the file, it looks like the area that is covered mainly by proposed sand filter #2 (the DA on the left in diagram 1) is constructed per the 2014 plans because the infiltration basin is certified. It looks like you all plan to reconfigure that area, take out the infiltration basin, and use a sand filter. The area that goes to sand filter #1 is being redeveloped from area that was not previously permitted to be redeveloped. Diagram 3 is on file from the 2014 permit. It shows the impervious area that was in place in 1981. (State Stormwater permitting began in 1988, and so the 2014 engineer submitted that to establish that he didn't have to treat all of the impervious area on the tract.) In 2014, the engineer showed that his drainage area contained impervious area that was in place well before 1988, but since it drained to the infiltration basin he treated all of the impervious area in the basin. (As I am sure you know, that is because all impervious in a drainage area has to be accounted for in order to ensure that it can all "fit" in the treatment facility). There was a small section of impervious area, as shown in Diagram 4, that he could not collect (likely because the driveway had to meet the crown of an existing road.) In retrospect, I probably should have quantified that amount of impervious in the permit. But, I did not (probably because it was so small). I have been trying to figure out the best way to document the redevelopment of this site, especially since they have been (and may continue to) make regular changes to the permit. Per .1002(41) and GS143-214.7, redevelopment must have impervious that is equal or less than the previous project and provide equal or better stormwater treatment. If the footprint of impervious is being increased, then the project falls under .1003(3)(d) and it needs a high -density permit for the net increase of impervious area. I have talked with other staff here to determine the best way to go about this. There are at least two ways, but there may be others. The most complete method would be to quantify the impervious area inside the entire project area using a pre-1988 map. Then, demonstrate that permit modifications do not exceed that amount, and that they provide equal or better treatment of impervious area. Or, the other way to do this is to compare pre-1988 with the proposed design on a drainage -area basis without addressing the entire site. We will have to work this out tomorrow.

We appreciate every effort to move up the review date. Normally we would not request this but we are receiving FY13 funds ($15M) for the construction of a new National Guard Readiness Center to be constructed on the same land as the current which was damaged by Act of Nature (Hurricane Irene 2011). Due to this being FY13 funds, they must be awarded by 30SEP2017 or they expire and the project will not happen. The timeline we are up against is the EN reviews must be completed and the 30 day period also completed prior to 17 AUG 2017 in order not to delay the already stringent timeline. This new NCNG Readiness Center will additionally be an economic asset to the Wilmington area. Again, we certainly appreciate any effort to get this review completed as soon as possible.

Hi LTC Moody: After hearing third -hand about your situation, I wanted to reach out to you directly. We make every effort to accommodate client schedules, but reviews are scheduled based on when the complete requests are received in our system and are spaced to allow the individual attention that is needed to expedite the Express Permit application reviews. We have a very limited staff available to conduct Express Reviews. In this case, after conversing via emails with Ms. Dudick, this review was already moved up once in our scheduling by more than a week by switching with the NGRC project in Jacksonville. I have now reached out to additional staff to see if they can accommodate your request, and I will let you know when our office is able to review your project. I will be in touch soon.

The quickness of the review is directly proportional to the completeness of the initial permit application packet that is brought to and discussed in the submittal meeting. The review meeting is scheduled so that the reviewer is able to put their attention on that particular project immediately, but it is a balancing act between ongoing Express reviews in house already with the reviewer and when the reviewer will be able to issue the permit from the latest Express submittal. The 30 days covers the reasonable assumption that two rounds of additional information will be needed from the applicant to complete the review. The more complete the application, the faster the overall turnaround for permit issuance. I'll be in touch on Monday with a date that a reviewer will be able to meet concerning the Express Review. Let me know of any other issues.
