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 references DEMLR as the Division responsible for issuance of the permit. The Wilmington Regional Office received a complete, modified State Stormwater Management Permit Application for the subject project on July 16's, 2020. Staff review of the plans and specifications has determined that the project, as proposed, complies with the Stormwater Regulations set forth in Title 15A NCAC 02H.1000 (1995 Rules) as amended on January 1, 2017 (2017 Rules). We are hereby forwarding modified Permit No. SW8 970408 dated July 15'b, 2020, for the construction of the built -upon areas (BUA) and stormwater control measures (SCMs) associated with the subject project. This permit shall be effective from the date of issuance until March 12, 2022 and the project shall be subject to the conditions and limitations as specified therein and does not supersede any other agency permit that may be required. 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. Please refer to Attachment C for a detailed description of the current proposed major modification. This cover letter, attachments, and all documents on file with DEN LR shall be considered part of this permit and is herein incorporated by reference.
