Cone, Vice President Blue Gem, Inc. 1846 Banking Street Greensboro, NC 27408 Subject: Stormwater Management Permit No. SW8 991201 Permit Transfer / Permit Extension / Approved Plan Revision Porter's Neck South Plaza (aka Gold's Gym) High Density Commercial Project New Hanover County Dear Mr. Cone: John E. Skvada, III Secretary 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 (DEMLR). Please note that the attached updated and transferred permit now 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 Division of Energy, Mineral and Land Resources 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 up 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 an extension of up to four (4) years. On February 7, 2014, the Division of Energy, Mineral and Land Resources (DEMLR) received a completed Name/Ownership Change Form for the subject project. A file review and site inspection had previously been performed on November 4, 2013 by DEMLR staff which noted several deficiencies. On October 29, 2014, the consultant submitted revised plans and a certification that the required repair work and plan revisions had been completed. The revised plans show the removal of 587 square feet of previously permitted sidewalk to cover the addition of 587 square feet of building. The site was reinspected on December 9, 2014 and as noted, in the enclosed inspection report, the site is currently in compliance with the terms and conditions of the state stormwater permit. As indicated on the Name/Ownership Change form, you have acknowledged receipt of a copy of the permit, which includes the application and supplement forms, a copy of the designer's certification, a copy of the approved plans and a copy of the required Operation and Maintenance agreement from the previous permittee. By acknowledging receipt of the permit, and by signing the Name/Ownership Transfer form, you have accepted the responsibility for complying with the terms and conditions outlined in the permit. The Division is hereby notifying you that permit SW8 991201 has been transferred on December 10, 2014 and to remind you that this permit shall be effective until May 24, 2024, which includes all the extensions. For your records, please find enclosed a copy of the updated permit, a copy of the most recent inspection report, and a copy of the signed Name/Ownership Change form. Please keep this cover letter and permit on file at all times. This project is subject to the conditions and limitations as specified in the updated permit. Please pay special attention to the conditions listed in this permit regarding the Operation and Maintenance of the BMP(s), recordation of deed restrictions, 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.

When using the Division SA/DA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non- standard table entries. 2. In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide 90% TSS removal. The NCDENR BMP manual provides design tables for both 85%TSS removal and 90% TSS removal. II.

Fonn SWU-102 Rev 3.99 Page 2 of 4 Maintenance activities shall be performed as follows: After every significant runoff producing rainfall event and at least monthly: a. Inspect the wet detention system for sediment accumulation, erosion, trash accumulation, vegetated cover, and general condition. b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within 2 to 5 days as designed. 2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative cover to maintain a maximum height of six inches, and remove trash as needed. 3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain proper functioning. 4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed of in an appropriate manner and shall not be handled in a manner that will adversely impact water quality (i.e. stockpiling near a wet detention basin or stream, etc.). The measuring device used to determine the sediment elevation shall be such that it will give an accurate depth reading and not readily penetrate into accumulated sediments. When the permanent pool depth reads 4.5 feet in the main pond, the sediment shall be removed. When the permanent pool depth reads 2.25 feet in the forebay, the sediment shall be removed.
