All previous references to DWQ will remain in older permits issued prior to August 1, 2013 until they are modified. Please note that this permit will now reference DEMLR as the Division responsible for enforcement 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 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. The Division of Energy, Mineral and Land Resources received a complete 8-year Permit Renewal Application for the subject permit on March 24, 2023. The Division is hereby notifying you that permit SW8080 has been renewed, updated, and re-issued on April 4,2023, as attached. As requested, a copy of the current operation and maintenance agreement is also enclosed. Please be aware that the renewal and re-issuance of this stormwater permit does not imply that the site is currently in compliance. This permit shall be effective until May 9, 2030,which includes all available extensions,_and does not supersede any other agency permit that may be required. The project shall be subject to the conditions and limitations as specified therein. This permit does not impose new or increased stonnwater control requirements; it clarifies the rules and requirements of this program to provide you with a better understanding of your obligations under this permit. Failure to comply with these requirements will result in future compliance problems. Please note that this permit is not transferable except after notice to and approval by 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).

This system (check one): ❑ does ® does not incorporate a vegetated filter at the outlet. This system (check one): ❑ does ® does not incorporate pretreatment other than a forebay. Important maintenance procedures: — Immediately after the wet detention basin is established,the plants on the vegetated shelf and perimeter of the basin should be watered twice weekly if needed,until the plants become established (commonly six weeks). — No portion of the wet detention pond should be fertilized after the first initial fertilization that is required to establish the plants on the vegetated shelf. — Stable groundcover should be maintained in the drainage area to reduce the sediment load to the wet detention basin. — If the basin must be drained for an emergency or to perform maintenance,the flushing of sediment through the emergency drain should be minimized to the maximum extent practical. — Once a year,a dam safety expert should inspect the embankment. After the wet detention pond is established,it should be inspected once a month and within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County).
