Box 1807 Salisbury, NC 28145 NORTH CAROLINA Environmental Quality Subject: Approved Minor Modification Stormwater Permit No. SW8130913 Stevenson Chevy Swansboro Onslow County Dear Ms. Stevenson: On July 27, 2020, the Wilmington Regional Office of the Division of Energy, Mineral and Land Resources received and accepted a complete minor modification application for changes to the approved plans for Stormwater Management Permit Number SW8 130913. It has been determined that the nature of the proposed change meets the definition of a minor modification in that it does not result in an increase in the size of the permitted stormwater control measure (SCM) and does not increase the amount of built -upon area. Please refer to Attachment C for a detailed description of the current proposed minor modification and a list of all the past modifications approved during the effective period of the permit. We are forwarding you an approved copy of the modified plans for your files. Please replace the old approved plan sheet(s) with the new one(s). Please replace the previously issued permit with the revised permit, dated October 13, 2020, attached. This revised 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. Please be aware that all terms and conditions of the permit issued on October 11, 2013 and modified as attached, remain in full force and effect. Please also understand that the approval of this minor modification to the subject State Stormwater Permit is done on a case -by -case basis. Any other changes to this project must be approved through this Office prior to construction. The approval of this minor modification does not preclude the permittee from complying with all other applicable statutes, rules, regulations or ordinances which may have jurisdiction over the proposed activity, and obtaining a permit or approval prior to construction. If you have any questions concerning this matter, please contact Garrett Zorda in the Wilmington Regional Office at (910) 796-7215 or garrett.zorda@ncdenr.gov.

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. Important maintenance procedures: - Immediately following construction of the stormwater wetland, bi-weekly inspections will be conducted and wetland plants will be watered bi-weekly until vegetation becomes established (commonly six weeks). - No portion of the stormwater wetland will be fertilized after the first initial fertilization that is required to establish the wetland plants. Stable groundcover will be maintained in the drainage area to reduce the sediment load to the wetland. --- Once a year, a dam safety expert should inspect the embankment. After the stormwater wetland is established, I will inspect it monthly and within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County).

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. I, John O Stevenson , 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 Stevenson Chevrolet (Swansboro) The following covenants are intende o eapure ongoing compliance with State Stormwater Management Permit Number�1V, as issued by the Division of Water Quality u under the Stormwater Management e atrons. 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 Water Quality. 5. Alteration of the drainage as shown on the approved plan may not take place without the concurrence of the Division of Water Quality. 6. The maximum allowable built -upon area per lot is 366 452 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 Total 366.452 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. Z 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 runoff 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 Water Quality and receive a permit prior to construction. 9. The project and each lot will maintain a 30** foot wide vegetated buffer between all impervious areas and surface waters. **50 foot for projects located in the 20 coastal counties.
