Holz, Manager 106 Manatee Street Cape Carteret, NC 28584 Subject: Permit Renewal Post -Construction Stormwater Management Permit No. SW8080717 H & S Hotel Carteret County Dear Mr. Holz: Effective August 1, 2013 the Post -Construction Stormwater Management Program has been transferred from the Division of Water Quality ("DWQ") to the Division of Energy, Mineral and Land Resources ("DEMLR" ). 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 November 17'", 2022. The Division is hereby notifying you that permit SW8080717 has been renewed, updated, and re -issued on January 3rd, 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 December 30', 2029, 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 thisprogram to provide you with a better understanding of your obligations under this permit. Failure to comply withthese 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). 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. ®E,QZ� North Carolina Department of Environmental Quality I Division of Energy, Mlneraland land Resources Wilmington Regional Office 1 127 Cardinal Drive Extension I Wilmington, North Carolina 28405 rvwm cer+wrae 910.796.7215 State Stormwater Permit No. SW8080717 Page 2 of 2 If you have any questions concerning this permit, please contact Aisia Freeman in the Wilmington Regional Office, at phone # (910) 796-73 18 or Aisia.freeman@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 after the filter strip is established, any newly planted vegetation will be watered twice weekly if needed until the plants become established (commonly six weeks). — Once a year, the filter strip will be reseeded to maintain a dense growth of vegetation — Stable groundcover willbe maintained in the drainage area to reduce the sediment load to the vegetation. — Two to three times a year, grass filter strips will be mowed and the clippings harvested to promote the growth of thick vegetation with optimum pollutant removal efficiency. Turf grass should not be cut shorter than 3 to 5 inches and may be allowed to grow as tall as 12 inches depending on aesthetic requirements (NIPC, 1993). Forested filter strips do not require this type of maintenance. — Once a year, the soil will be aerated if necessary. — Once a year, soil pH will be tested and lime will be added if necessary. After the filter strip is established, it will be inspected quarterly and within 24 hours after every storm event greater than 1.0 inch (or 1.5 inches if in a Coastal County). Records of operation and maintenance will be kept in a known set location and will be available upon request. Inspection activities shall be performed as follows.
