VAN DER VAART Energy, Mineral and Land Resources ENVIRONMENTAL QUALITY April 12, 2016 Mr. David Sneeden, General Manager Oak Ridge Properties at Olde Point, LLC 519 Market Street Wilmington, NC 28401 Subject: State Stormwater Management Permit No. SW8141108 Oak Ridge Properties at Olde Point High Density Subdivision Alternative Design Project Pender County Dear Mr. Sneeden: Semwy TRACY DAVIS Dimdor The Wilmington Regional Office received a complete, modified State Stormwater Management Permit Application for Oak Ridge Properties at Olde Point on April 12, 2016. Staff review of the plans and specifications has determined that the project, as proposed, will comply with the Stormwater Regulations set forth in Session Law 2008-211 for a minor modification, and Title 15A NCAC 2H.1000. We are forwarding modified Permit No. SW8 141108 dated April 12, 2016, for the construction, operation and maintenance of the BMP's and built -upon area associated with the subject project. The modifications covered by this permit include: 1. Changes the previously approved BUT from a wet detention pond to an alternative design lateral infiltration basin with a crushed limestone Permeable Reactive Barrier. The BMP will be studied and monitored by Dr. William Hunt, P.E., of North Carolina State University to determine if the BUT can meet the state's pollutant removal requirements and be used for future projects. 2. Reallocates the BUA assigned to the lots. 3. Splits Lot 4 into Lots 4 and 4A. 4. Construction on Lots 4 and 4A is permitted under this master permit. This permit shall be effective from the date of issuance until Februalry 3.2023. 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, and the procedures for changing ownership, transferring the permit, and renewing the permit. Failure to establish an adequate system for operation and maintenance of the stormwater management system, to record deed restrictions, to transfer the permit, or to renew the permit, will result in future compliance problems. Please note that per Section L7 of the permit, the proposed construction on Lots 4 and 4A is NOT approved until after a copy of the recorded deed restrictions is submitted to the Division. 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 (3 0) 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.NCOAII.com.

I will keep a maintenance record on this BMP. This maintenance record will be kept in a log in a known set location. Any deficient BMP elements noted in the inspection will be corrected, repaired or replaced immediately. These deficiencies can affect the integrity of structures, safety of the public, and the removal efficiency of the BMP. If this BMP is used as a sediment control device, then prior to being put into service any excess sediment shall be removed. The filter media shall not be placed in the basin until after all sediment is removed, the upstream drainage area is stabilized and the BMP is ready to be utilized for its intended purpose. After the lateral infiltration basin is established, it should be inspected once a month and within 24 hours after every storm event greater than 1.0 inches (1.5 inches if in a Coastal County). Records of operation and maintenance should be kept in a known set location and must be available upon request. Inspection activities shall be performed as follows.

Once operational the system will be studied by academic staff from North Carolina State University for a period of 2 yeras. During this study period the system shall be monitored periodically to quantify the removal of pollutants and for the ability of the BMP to treat stormwater runoff. Due to the fact that the proposed system is heavily dependent on the functionin media the following additional maintenance items shall be performed. EG . During inspections of the systern as prescribed in the third parag h t! this documen the BMP filter media shall be inspected. BY: 2. Particular attention shall be paid to the ability of the media to allow t e dewatering of the BMP occur after a storm event. 3. The inability of the media to allow the runoff to pass through the system shall be determined by comparing the design storm size and the calculated draw down time. If the temporary storage of the BMP does not draw down within a reasonable time then the source of the clog shall be identified. If the source of the clogging is determined to be the filter media then steps to alleviate the clogging shall be performed. 4. If the source of the clogging is determined to be at the surface of the material then then the surface should be cleared of any trash, debris or vegetation. After any obtrusive material is removed the surface of the media shall be raked to break up any clumps of sediment in the media surface. 5. If the surface of the media is inundated with sediment then a layer of filter media shall be removed and replaced with new media to a depth determined by a field sampling of the material. This field sampling shall include but not be limited to removing a small portion of the material to determine the depth of sediment accumulation. 6. The above steps and methodology shall be amended as needed with input from the academic staff studying the BMP and input from a design professional. nECEIVED Bg DEC 14 2015 BY: Permit Number: {to be provided by DWQ} I acknowledge and agree by my signature below that I am responsible for the performance of the maintenance procedures listed above.

Deed restrictions and protective covenants are necessary to ensure that the development maintains a built -upon area consistent with the design criteria used to size the stormwater control facility. 1, _David Sneeden , acknowledge, affirm and agree by my signature below, that I will cause the following deed restrictions and covenants to be recorded prior to the sale of any lot within the project known as _Oak Ridge Properties at Olde Point 1. The following covenants are intended to ensure ongoing compliance with State Stormwater Management Permit Number_SW8 141108 , as issued by the Division of Energy, Mineral and Land Resources under the Stonnwater Management Regulations. 2. The State of North Carolina is made a beneficiary of these covenants to the extent necessary to maintain compliance with the stormwater management permit. 3. These covenants are to run with the land and be binding on all persons and parties claiming under them. 4. The covenants pertaining to stormwater may not be altered or rescinded without the express written consent of the State of North Carolina, Division of Energy, Mineral and Land Resources. 5. Alteration of the drainage as shown on the approved plan may not take place without the concurrence of the Division of Energy, Mineral and Land Resources. 6. The maximum allowable built -upon area per lot is _See attached square feet. *Note: If the BUA per lot varies, please substitute the following statement for the one above and provide a complete listing of the proposed BUA for each lot: The maximum built -upon area per lot, in square feet, is as listed below: Lot # BUA Lot # BUA Lot # BUA Lot # BUA _See attached This allotted amount includes any built -upon area constructed within the lot property boundaries, and that portion of the right-of-way between the front lot line and the edge of the pavement. Built upon area includes, but is not limited to, structures, asphalt, concrete, gravel, brick, stone, slate, coquina and parking areas, but does not include raised, open wood decking, or the water surface of swimming pools. 7. All runoff from the built -upon areas on the lot must drain into the permitted system. This may be accomplished through a variety of means including roof drain gutters which drain to the street, grading the lot to drain toward the street, or grading perimeter swales to collect the lot r%1noff and directing them into a component of the stormwater collection system. Lots that will naturally drain into the system are not required to provide these additional measures. 8. The owner of each lot, whose ownership is not retained by the permittee, is required to submit a separate stormwater permit application to the Division of Energy, Mineral and Land Resources and receive a permit prior to construction. 9.
