NOTE: A minor modification application processing fee of $100 was received by DCM for this project. PAT MCCRORY Governor DONALD R. VAN DER VAART Secretary Environmental Quality MEMORANDUM TO: Heather Coats Assistant Major Permits Coordinator FROM: Robb Mairs Field Representa tive, Wilmington THRU: Debra Wilson 9 DCM, District Manager, Wilmington DATE: October 20, 2015 SUBJECT: Minor modification request, State Permit No. 151-01, New Hanover County, Mason Inlet Relocation Project (MIRP) Mr. Layton Bedsole, Shore Protection Coordinator with the New Hanover County Engineering Department, is requesting a Minor Modification to State Permit No. 151-01 to allow maintenance excavation within the reaches of the US Army Corps of Engineers (USACE) AIWW as well as Mason Creek east through the Mason Inlet reach. As noted in the provided USACE July 22, 2015 notification, the AIWW maintenance dredging is in accordance with Federal Permit Action ID No. 199901052, Condition 17 of the MIRP. Based on the provided Spring 2015 bathymetric surveys, approximately 32,000 cubic yards (cy) of material is within the AIWW crossing and approximately 421,000 cy within Mason Creek through the Inlet reach would be hydraulically removed from the shoaled areas within the project templates. Mr. Bedsole states that New Hanover County (NHC) and the Mason Inlet Preservation Group (MIPG) anticipate beneficial reuse of the shoaled sand within the 10,000 linear foot placement area along the southern portion of Figure "8" Island. Mr. Bedsole also states that if necessary based on the recent weather events associated with Hurricane Joaquin, the placement area on the north end of Wrightsville Beach may also be necessary. Further, he states that neither beneficial use would receive more than an average of 50 cy per linear foot placed. State Permit No. 151-01 was originally issued to New Hanover County on November 28, 2001 and was recently modified on November 5, 2013, which authorized the removal of the permit condition that addresses the biological monitoring requirements for the Mason Inlet Relocation Project. This recent modification conditioned that the requirement by the applicant has been satisfied and that additional biological monitoring under State Permit No. 151-01 is no longer required. This permit was subject to extension by the Session Law 2009-406, as amended by Session Law 2010-177, the Permit Extension Act. The new expiration date for State Permit No. 151-01 is December 31, 2015 (Please see Project Narrative and attachments).

This office has no objections to the modification of State Permit No. 151-01.

Wilmington, NC 28405 Re: Mason Inlet Relocation Project Permit Minor Modification Request, Permit Number 15 1 -01 Expiration Date, 31 December 2015 Maintenance Event Dear Mr. Mairs, New Hanover County (NHC), in concert with the Mason Inlet Preservation Group (MIPG), is requesting a North Carolina Division of Coastal Management (NCDCM) permit minor modification allowing a Mason Inlet Relocation Project (MIRP) maintenance event. This maintenance event includes the Atlantic Intracoastal Waterway (AIWW) crossing's maintenance dredging as well as Mason Creek east through the Mason Inlet reach. As noted in the attached USACE 22 July 2015 notification, the AIWW maintenance dredging mandate is in accordance with Action ID. 199901052, Condition 17 of the MIRP. Based on the attached Spring 2015 monitoring transects, the AIWW crossing holds approximately 32,000 cubic yards (cy) of shoaled sand and approximately 421,000 cy within Mason Creek east through the Mason Inlet reach. Considering the USACE's AIWW crossing mandate and the shoaled volume within the remaining inlet complex, dredge plant mobilization and estimated shoaled yardage suggests an inlet maintenance event encompassing all authorized reaches. NHC and MIPG anticipate beneficial reuse of the shoaled sand within the 10,000-foot linear placement area on Figure Eight Island. However if necessary based on weather events (Joaquin), the placement area on north Wrightsville Beach may also be necessary. Neither beneficial reuse area will received more than an average of 50cy/lf placed. The following June 2015 aerial figure depicts the MIRP's component reaches. Routinely, the eastern most maintenance has been landward of the Colregs demarcation line. Currently, the 2015 Colregs line is approximately along the 5+00 survey transect. Market forces have historically determined dredge plant size and capability in terms of ocean -certified dredge plant usage and their operational rates. NHC anticipates a hydraulic pipeline dredge plant similar to the USACE's routinely contracted plants for maintenance dredging at the shallow draft AIWW inlet crossings. RECEIVED DCM WILMINGTON, NC 0 C T 0 2 2015 A preconstruction meeting will be held locally prior to initiating the maintenance dredging. NHC appreciates the guidance and support provided by the Division and its consideration of our permit minor modification request. The NCDCM permit minor modification fee of $100.00 will be hand delivered to the Wilmington Regional Office.

Green Meadows Drive Wilmington, NC 28403 Wilmington, NC 28405 Engineering Firm #P-0743 The project area was surveyed by GBA during May\June 2015 utilizing RTK GPS techniques referenced to the survey monument "Satelite". The information depicted on the attached figures represents the results of the survey made on the date indicated and can only be considered as indicating general conditions at that time. The survey was referenced horizontally to the North Carolina State Plane NAD83 in survey feet and vertically to NAVD88 in survey feet. The relationship between NAVD88 and the tidal datums of MLW and MHW is shown in the figure below.
