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 2009406. 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 June 15, 2022. The Division is hereby notifying you that permit SW8080744 has been renewed, updated, and re -issued on June 16, 2022, as attached. 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 November 5, 2028, 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 stormwater 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 flearings (OAH). The written petition must conform to Chapter 150B of the North Carolina General Statutes and must be filed with the OAH within thirty (30) 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.NCOAH.com. Unless such demands are made this permit shall be final and binding. If you have any questions concerning this permit, please contact Ashley Smith in the Wilmington Regional Office, at (910) 796-7215 or ashleym.smith@ncdenr.gov.
