Director Division of Water Quality August 1, 2006 Mr. Travis Tyndall, Manager Inland Properties Group, LLC 2894 Belgrade-Swansboro Road Maysville, NC 28555 Subject: Approved Plan Revision Morada Bay Sections 1, 2 and 3 Stormwater Project No. SW8 040919 Mod. Carteret County Dear Mr. Tyndall: On May 9, 2006, the Wilmington Regional Office received a plan revision for Stormwater Management Permit Number SW8 040919. Additional information needed to complete the review was received on August 1, 2006. The proposed revisions include the deletion of curb outlet swales 1, 2, and 5. The runoff from these areas will be redirected into Swales 3 & 4. It has been determined that a formal permit modification is not required for the proposed changes. We are forwarding you an approved copy of the revised plans for your files. Please replace the old approved plan sheets with the new ones. Please be aware that all terms and conditions of the permit issued on September 19, 2005, remain in full force and effect. Please also understand that the approval of this revision to the approved plans for the subject State Stormwater Permit is done on a case -by -case basis. Any other changes to this project must be approved through this Office prior to construction. The issuance of this plan revision does not preclude the permittee from complying with all other applicable statutes, rules, regulations or ordinances which may have jurisdiction over the proposed activity, and obtaining a permit or approval prior to construction. If you have any questions concerning this matter, please do not hesitate to call me at (910) 796-7335.
