Plans are also attached. New Hanover County received a permit for the initial project on November 29, 2001 (CAMA/D&F #151-01). The ACE AID # was SAW- 1999-01052. DWR Project # 000008. The permit has been kept active and modified several time over the years. Maintenance events with beach nourishment were approved in 2007, 2010, and 2012 and 2015. The 2015 event was authorized by DCM through a minor modification on December 11, 2015 for the dredging of 45,251 cubic yards of material from the Atlantic Intracoastal Waterway (AIWW) crossing and 429,439cy from Mason Inlet and Mason Creek (a total volume of 474,690 cy), with the associated beach nourishment along 10,500 linear feet of Figure 8's shoreline. Mr. Layton Bedsole, acting on behalf of New Hanover, has requested a modification of the permit to allow for another maintenance event this coming winter with associated beach nourishment on Figure 8. Surveys provided show the channel has migrated south within the inlet and as proposed, up to 450,000 cubic yards of material would be excavated from the AIWW crossing, Mason Inlet and Mason Creek. Please note water depths shown on the plans are relative to NAVD88 and not Mean Low Water (MLW). Please let me know if you have any questions or concerns by August 30, if possible.

Wilmington, NC 28405 Email Transmittal: heather. coats(kncdenr.gov Re: Mason Inlet Relocation Project Minor Modification Request, Permit Number 15 1 -01 Expiration Date, 31 December 2020 FY2020 Maintenance Event Ms. Coats, New Hanover County (NHC), in concert with the Mason Inlet Preservation Group (MIPG), is requesting a minor modification to Major Permit Number 15 1 -01 expiration date 31 December 2020. NHC is requesting a minor modification allowing a Mason Inlet Relocation Project (MIRP) maintenance event. The scope will include potential dredging needs within the authorized reaches of the Atlantic Intracoastal Waterway (AIWW) crossing, the Mason Creek reach east through the Banks Channel confluence and ending with Mason Inlet. The maintenance event will realign the system's thalweg within the authorized template corridor. The MIRP's most recent relocation maintenance event occurred in 2016. The Project Reaches, Spring 2019 Bathymetrics and June Aerial figures depict the MIRP's components, most recent surveyed elevations and most recent aerial. The FY2020 maintenance event is substantiated by authorization triggers: (1) migration of the northern bank approaching the southern engineered corridor and (2) a minimum shoaled template volume of 300,000 cubic yards (cy). Based on the attached bathymetrics, 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 or additional shoaling, the placement area on north Wrightsville Beach may also be accessed. Neither beneficial reuse area will receive more than the authorized average of 50 cy/linear foot placed. As previously managed since 2002, the eastern most maintenance has been landward of the Colregs demarcation line. Currently, the Colregs line is approximately along the 4+00 survey transect. Market forces have historically determined dredge plant size and capability in terms of potential ocean -certified dredge plant usage and their operational rates. A preconstruction meeting will be held prior to initiating the maintenance relocation (environmental dredging window of 15 November 2019 — 31 March 2020). Spring 2019 Bathymetrics (Gahagan & Bryant) June 2019 Aerial (Lana Mgt. Group) NHC appreciates the guidance and support provided by the Division and the consideration of our permit's minor modification request. The NCDCM minor modification fee of $100.00 will be hand delivered to the Wilmington Regional Office.

Plans are also attached. New Hanover County received a permit for the initial project on November 29, 2001 (CAMA/D&F #151-01). The ACE AID # was SAW- 1999-01052. DWR Project # 000008. The permit has been kept active and modified several time over the years. Maintenance events with beach nourishment were approved in 2007, 2010, and 2012 and 2015. The 2015 event was authorized by DCM through a minor modification on December 11, 2015 for the dredging of 45,251 cubic yards of material from the Atlantic Intracoastal Waterway (AIWW) crossing and 429,439cy from Mason Inlet and Mason Creek (a total volume of 474,690 cy), with the associated beach nourishment along 10,500 linear feet of Figure 8's shoreline. Mr. Layton Bedsole, acting on behalf of New Hanover, has requested a modification of the permit to allow for another maintenance event this coming winter with associated beach nourishment on Figure 8. Surveys provided show the channel has migrated south within the inlet and as proposed, � North Carolina Wildlife Resources Commission 0 Gordon Myers, Executive Director MEMORANDUM TO: Heather Coats Division of Coastal Management North Carolina Department of Environmental Quality FROM: Maria T. Dunn, Coastal Coordinator Habitat Conservation Division DATE: September 13, 2019 SUBJECT: CAMA Minor Modification for New Hanover County and Mason Inlet Preservation Group, Permit No. 151-01, New Hanover County, North Carolina. Biologists with the North Carolina Wildlife Resources Commission (NCWRC) reviewed the minor modification with regard to impacts on fish and wildlife resources. The project site is located within the Mason Inlet complex, including Wrightsville Beach and Figure Eight Island. Our comments are provided in accordance with provisions of the Coastal Area Management Act (G. S. 113A-100 through 113A-128), as amended, Sections 401 and 404 of the Clean Water Act, as amended, and the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 US.C. 661 et seq.). The applicants propose a Mason Inlet Relocation Project (MIRP) maintenance event. Dredging would occur within the authorized reaches of the AIWW crossing, the Mason Creek reach east through the Banks Channel confluence, and Mason Inlet. The event would realign the system's thalweg within the authorized template corridor. The last event occurred in 2016. Material removed from the system would be placed within the 10,000' placement area on Figure Eight Island, though placement on Wrightsville Beach may occur depending on weather or shoaling. A pre -construction meeting would occur prior to initiating the maintenance event_ Dredging activities and material placement on the beach would adhere to an April 1— November 15 moratorium. The NCWRC has reviewed the minor modification request and does not believe the proposal will have significant impacts on wildlife resources as long as all conditions on the permit are upheld, including the April 1— November 15 moratorium. Only beach compatible material should be placed on the shore. If at any time during the operation incompatible material is placed, it must be removed and the beach remediated outside the moratorium dates. Since the submission of the proposal, Hurricane Dorian passed through the area. We strongly recommend the applicants consider the proposal and how conditions may have changed If the proposal must be amended, we request notification and updated information. We appreciate the opportunity to review and comment on this permit application_ If you need further assistance or additional information, please contact me at (252) 948-3916.
