The law extends 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 May 12, 2014, the Division of Energy, Mineral and Land Resources (DEMLR) received a complete permit Name/Ownership Change Form from Clancy & Theys Construction Company for the subject project.

As indicated on the Name/Ownership Change form, you have acknowledged that you have not received copies of the permit, which includes the application and supplement forms, the approved plans and copy of the required Operation and Maintenance agreement from the previous permittee.

The Division is hereby notifying you that permit SW8 011102 has been transferred on July 28, 2014 and to remind you that this permit shall be effective until February 20, 2016, which includes the extensions.

When using the Division SAMA 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. 1n 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°/0 TSS removal. II.

WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the vegetated filter if one is provided. This system (check one) ❑ does X does not incorporate a vegetated filter at the outlet. This system (check one) ❑ does X does not incorporate pretreatment other than a forebay. Form SWU-102 Rev 3.99 Page 2 of 4 Maintenance activities shall be performed as follows: I . 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 4,875 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.
