All previous references to DWQ will remain in older stormwater 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 issuance of the permit. The Wilmington Regional Office received a complete 8 year Stormwater Management Permit Renewal Application for the subject project on July 1, 2021. The Division is hereby notifying you that permit SW8 130111 has been renewed on July 9, 2021, and shall be effective until February 6, 2029. For your records, please find enclosed a renewed, updated, and re -issued permit and a copy of the renewal application. Please keep this permit on file at all times. Please note that the renewed, updated, and re -issued permit does not impose new or different terms; it merely restates some of the previous terms to provide you with a better understanding of your obligations under the permit. The renewal and reissuance of this stormwater permit does not imply that the site is currently in compliance with the terms and conditions of this state stormwater permit. The plans originally approved on February 6, 2013, will remain in full force and effect in accordance with the regulations set forth in Title 15A NCAC 2H.1000.

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: — The drainage area will be carefully managed to reduce the sediment load to the infiltration basin. — Immediately after the infiltration basin is established, the vegetation will be watered twice weekly if needed until the plants become established (commonly six weeks). — No portion of the infiltration basin will be fertilized after the initial fertilization that is required to establish the vegetation. — The vegetation in and around the basin will be maintained at a height of approximately six inches. After the infiltration basin is established, it will be inspected once a quarter and within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County).
