Schilsky, Owner Schilsky Chiropractic Center 445 A Western Blvd Jacksonville, NC 28540 Subject: State Stormwater Management Permit No. SW8 020502 Schilsky Chiropractic Center High Density Subdivision Wet Detention Pond Project Onslow County Dear Mr. Schilsky: seawffly TRACY DAVIS Dhedor Effective August 1, 2013, the State Stormwater program was transferred from the Division of Water Quality (DWQ) to the Division of Energy, Mineral and Land Resources (DEN LR). All previous references to DWQ will remain in older stormwater permits issued prior to August 1, 2013 until they are modified. Please note that this permit references DEMLR as the Division responsible for issuance of the permit. . The Wilmington Regional Office received a complete, modified State Stormwater Management Permit Application for Schilsky Chiropractic Center on December 7, 2016. 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 2H.1000. We are forwarding modified Permit No. SW8 020502 dated February 24, 2016, for the construction, operation and maintenance of the BMP's and built -upon area associated with the subject project. This permit shall be effective from the date of issuance until October 16,2016 and shall be subject to the conditions and limitations as specified therein. Please pay special attention to the conditions listed in this permit regarding the Operation and Maintenance of the BMP(s), recordation of deed restrictions, certification of the BMP's, procedures for changing ownership, transferring the permit, and renewing the -Ar permit. Failure to establish an adequate system for operation and maintenance of the stormwater management system, to record deed restrictions, to certify the BMP's, to transfer the permit, or to renew the permit, will result in f dure compliance problems. The following modifications are included and covered by this permit: 1. This permit originally approved 58,669 square feet of built -upon area for the First Citizen Bank based on the information presented in Permit No. SW8 010522. However, it was later discovered that Permit No. SW8 010522 was for a First Citizens Bank located several miles down the road. The First Citizens Bank associated with this project was permitted under SW8 000937, which allocated 60,755 square feet of built -upon area. This modification adds 2,086 square feet of built - upon area to the of1she lot for the First Citizens Bank as well as corrects the permit number associated with the Frist Citizens Bank project. 2. The modified permit does not.impose new or different terms, it merely restates some of the previous terms to provide you with a better understanding of your obligations under the permit. 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. You should contact the OAH with all questions regarding the filing fee (if a filing fee is required) and/or the details of the filing process at 6714 Mail Service Center, Raleigh, NC 27699-6714, or via telephone at 919-431-3000, or visit their website at www.NCOAH.com. Unless such demands are made this permit shall be final and binding.

VAN DER VAART Secretary TRACY DAVIS f j Director LAI o� Branch Manager First Citizens Bank 2555 Western Boulevard Jacksonville, NC 28546 Subject: State Stormwater Management Permit No. SW8 000937 First Citizens Bank 2555 Western Boulevard Project served by an Offsite System Onslow County Dear Branch Manager: On December 15, 2000, the Wilmington Regional Office of the former Division of Water Quality issued a high--density-wet-detention -pond-permit to Thomas-B. Morriss -VP --of First -Citizens Bank; -for the subject project. It has come to the attention of the Division that on October 18, 2002, this particular project was intended to be included as offsite drainage area in the Schilsky Office Park permit (SW8 020502). This allowed the Bank's previously permitted wet pond to be filled in because the runoff from the Bank's built -upon area would be treated in the Schilsky Office Park pond. Due to a clerical error, the Bank's existing permit was not corrected at that time to reflect a change in the regulated activity from high density wet detention to Offsite. This error was recently discovered when a letter requesting that the permit be renewed was sent to the Bank. Further investigation revealed that the permit application for the Schilsky Office Park referenced the wrong permit number for the First Citizens Bank of SW8 010522. The First Citizens Bank actually covered by the SW8 010522 permit is located several miles east of your location at 302 Western Boulevard, near White Street. To further complicate matters, the SW8 010522 Bank permit allocated a maximum of 58,669 sf of Built -upon area (BUA), which is the amount that was covered in the Schilsky permit as part of the permitted Offsite BUA treated in that pond. However, the correct permit for the First Citizens Bank located at 2555 Western Boulevard is SW8 000937. Unfortunately, the SW8 000937 permit allowed a maximum of 60,755 sf of BUA to be constructed. Since the Schilsky permit only covered 58,669 square, the difference of 2,086 square feet needs to be addressed. Please be advised that on December 7, 2015, the Division received a modified permit application for Schilsky Office Park to account for that additional 2,086 square feet of BUA. The original bank permittee, Mr. Thomas Morris, was advised of this situation in a June 12, 2015 letter sent by the Division, but he has not responded to date. The Division is concerned that either the mailing address is no longer valid, or Mr. Morris has retired or moved on. In either case, the Division would appreciate it if the Branch Manager could forward this letter to the appropriate person within the First Citizens Bank hierarchy who has the authority to handle situations with government -required permits. The Division is also requesting that the First Citizens Bank individual acknowledge these events and authorize the Division to change the regulated activity for SW8 000937 to "Offsite" so that the permit can be reissued. Please respond to this letter by February 15, 2016.

At the time Schilsky Office Park was permitted, the Bank already existed and had its own pond. On our database, there are 2 First Citizens banks located on Western Boulevard. Apparently, the permit associated with the Bank at the other end of Western Blvd. (SW8 010522) was incorrectly identified as being the permit for the bank within the Schilsky Office Park, which had a BUA of 58,669 sf. Who made this determination (Division or consultant) is not clear in the file. This incorrect existing BUA amount was simply drafted over into the Schilsky permit as being Offsite. However, when you look at the approved plans for SW8 010522 it is immediately clear that the Bank under that permit is not located in the Schilsky Office Park. The correct permit number for the existing Bank in Schilsky Office Park is SW8 000937 which has 60,755 sf of permitted BUA associated with it. If you want to take a look at these files and the approved plans, please set up a file review appointment through Cameron. The only wriggle room I see is that perhaps the 60755 sf number includes the entrance road into the Office Park since it was shown on the approved 000937 plan, and that the same entrance road may have been counted again as "street" area or "existing" area in the 020502 permit. If you can confirm what the actual BUA amount is for the 000937 Bank, using the approved 000937 plan, and excluding the entrance road, that would help.

All previous references to DWQ will remain in older stormwater permits issued prior to August 1, 2013 until they are modified. Please note that this letter references DEMLR as the Division responsible for issuance of the permit. On August 5, 2009, the Governor signed Session Law 2009-406. This law impacted any development approval issued by the former Division, of Water Quality under,Article 21 of Chapter 143 of the General Statutes, which was current and valid at any point between January 1, 2008, and December 31, 2010. The law extended the effective period of any stormwater permit that was set to expire during this time frame to three (3) years from its current expiration date. On August 2, 2010, the Governor signed Session Law 2010-177, which granted an extra year for a total of four (4) years extension. Accordingly, the subject permit shall now be effective from the date of issuance until October 18, 2016. Please retain a copy of this letter with your permit. Per 15A NCAC 2H.1003(h) (the stormwater rules), applications for permit renewals shall be submitted 180 days prior to the expiration date of the permit and must be accompanied by- a processing fee, which is currently set at $505.00. Please note that you will need to complete and submit a renewal application prior to April 18, 2016. If the property covered by the permit has been/will be sold or legally transferred to another entity or if the project name or permit holder has changed its name and/or mailing address, it is your responsibility as the permittee to submit a completed and signed Name/Ownership change form to DEMLR at least 30 calendar days prior to making the changes. Both the renewal application form and the permit transfer forms are available on our website at: http://Portal.ncdenr.orn/web/ir/state-stormwater-forms docs. Please note that the subject permit will also need to be corrected and modified. The 2002 permit included a First Citizens Bank as offsite drainage area. Unfortunately, the referenced permit number, SW8 010522, is incorrect. The correct permit number for that particular bank site located at 2555 Western Boulevard, is SW8 000937. Even more unfortunate, the amount of offsite BUA accounted for in the SW8 020502 permit for this bank is based on the SW8 010522 permitted BUA of 58,669 square feet. The BUA associated with the correct bank permit is 60,755 square feet. The pond will need to be reevaluated to account for this additional 2,086 sf of BUA. Since we are unable to ascertain who was at fault regarding this permit number error, you will not be charged a permit modification fee.

The Division has not received a response from you regarding the concerns outlined in that letter. Please note that ^er echedule of Compliance Condition II.14 of your permit, if the Director notifies you that the site does not meet one or more of the minimum requirements of the permit, then you are required to provide a written time schedule for modifying the site to meet the minimum requirements within the time frame specified in the notice. You must provide a written time schedule for addressing the permit compliance issues outlined in this letter by November 16. 2016. If you do not provide the requested written time schedule by that date, then per NCGS 143-215, you may be assessed a civil penalty of not more than $25,000 for failing to act in accordance with the terms, conditions or requirements of the stormwater permit. Furthermore, your failure to respond to the Division's letters could also be considered as abandonment of -the permit, which may allow the Director of the Division of Energy, Mineral and Land Resources to revoke the permit for just cause as set forth in NCAC 02H.1011. Revocation of the permit will mean that the project is no longer covered by a valid stormwater permit and therefore, the local government will not be able to issue any building permits until a new permit is issued. Ifa new permit has to be issued, the existing wet ponds will need to be redesigned and retro-fitted to meet current design standards.

This is to certify that the permitted facility has been installed in accordance with the permit, the approved plans, specifications and supporting documentation. If you have not already provided a Designer's Certification to our office, please include a copy with your permit renewal request and processing fee. A copy of the certification form is enclosed for your convenience.

Request that we completely collect and direct all storm water for the rear parking lot of Chiropractic office on lot 2A as approved on storm water plans. As previously reviewed and pictures forwarded the water had been redirected to the catch basin on the plan behind the dumpster pad at the rear of the Schilsky Chiropractic office; however, you felt that the redirection of the storm water was still allowing for seepage over the rip rap swale that was in place. Since this point I have added significant amounts of small 57 stone to prevent storm water seepage. 2. As it relates to deficiency item number two, you commented about the gravel parking lot extension to the existing parking area that was not noted on the original storm water plan. Please be reminded as per our discussion that this gravel parking lot is no longer owned by me and I have no control over this property and any attempt to remove this gravel parking lot extension could potentiate legal ramifications against me from the current land owner. I am aware however, that he is currently preparing a site plan and storm water plan for the property and will be clearing that property as soon as this storm water compliance concern is resolved. It is my understanding then that you will accept his modification permit request and he will be able to move forward with his site work which will ultimately remove the existing gravel parking lot that is on his property. 3&4. In regards to restoring pond number one, which is located on lot four, back in to compliance and good working order. This has taken place and all grades have been restored: stabilization, matting, and seeding have been put in place. Repair of the berm between the forbay and retention pond has occurred. Depths have been assessed and are within normal limits and the pond has been put under contract with Coastal Retention Pond Services and Mr. Tim Early to maintain the pond and keep it in good working order. This therefore also resolves item four which requested that we create a schedule for inspection and on -going maintenance of the storm water system. According to the signed operation and maintenance agreement enclosed, Mr. Early has prepared that document and is currently active on maintaining the pond inspection schedule. Lastly, you had documented a concern related to the wetland area half -way through the cul-de-sac being filled. I have submitted documentation from John Pierce to the US Army Corp of Engineers which validates the approval to fill that wetland area back in 2004. All documentation is attached. If I can be of any further assistance in this matter please do not hesitate to contact me directly at 910-340-7285. 1pr. Randy M.
