NOTES 3. 2. 1. ISLAND NEW DUMP PCN Additional Information: B.3d. This PCN addresses the need for written approval from NCDWR for the discharge of dredged material from two (2) CSRM project resulting from impacts associated with Hurricane Matthew, and three (3) projects involving maintenance dredging of coastal navigation channels (see below/maps attached). Maintenance dredging occurs on an as-needed basis to provide safe navigation to commercial, public, and private shipping and boating interests. Placement locations include oceanfront beaches, upland confined disposal facilities (CDFs), and unconfined bird nesting islands. The placement locations included in this PCN have been used in previous years and only occur on 3 to 5-year cycles. No new placement locations will be used pursuant to General Certifications approved in response to this PCN. 1. Ocean Isle and Wrightsville Beach CSRM projects: The projects involve the dredging of sandy material from the Shallotte Inlet borrow area and Masonboro Inlet and Banks Channel borrow areas with a hydraulic cutterhead suction dredge(pipeline), and pumping the material to the oceanfront beaches on Ocean Isle and Wrightsville Beaches, respectively. Beach placement activities on Ocean Isle Beach and Wrightsville Beach will be limited to the period of 16 November through 30 April for the protection of nesting sea turtles. The Corps is seeking authorization for these projects under GC 4099, Emergency Construction of Primary Dunes and Associated Excavation. See attached maps for project limits. 2. Wilmington Harbor Inner Ocean Bar: Maintenance dredging of Bald Head Island Channel 2 and Smith Island Channel. The dredging shall be accomplished by a hydraulic cutter suction dredge and/or a hopper dredge with pumpout capability (the environmental window for hopper dredging is 1 December – 31 March). Placement of beach quality (sand) dredged material will occur on Caswell and Oak Island Beaches, and will be limited to the period of 16 November – 30 April for the protection of nesting sea turtles. The Corps is seeking authorization for this project under GC 4095, Projects Eligible for USACE Regional General Permit 2878, Dredge and Discharge into Federally Authorized Navigation Channels. See attached maps for project limits. 3. Wilmington Harbor Anchorage Basin: Maintenance dredging of the Anchorage Basin, Between Channel, 32-ft Turning Basin, the North Carolina State Ports Authority (NCSPA) berth areas and Turning Basin Extension. The environmental work window for dredging the Upper Harbor channel reaches and state ports is 1 August – 31 January for the protection of juvenile shrimp and finfish. The Government furnished disposal area is the Eagle Island Cell No. 3 upland diked disposal area; the Corps is seeking authorization for this activity under GC 4090, Return Water from Upland Contained Disposal Areas. See attached maps for project limits. Dredged material (beach quality sand) from Horseshoe Shoal Channel shall be placed onto Ferry Slip and South Pelican Islands by control-of-effluent method; the environmental work window is 1 September – 31 March for the protection of nesting waterbirds. The Corps is seeking authorization for this under GC 4105, Activities Involving Control of Effluent Disposal. See attached maps for project limits. 4. Manteo et al. Interior Channels: Maintenance dredging of the Manteo Interior Channels, Rollinson Channel portions, Big Foot Slough, and Atlantic Harbor Channels. The dredging shall be performed by hydraulic pipeline dredge, and placement of dredged material will be on Islands H, D, L, MN, Parnell, Wells, Cora June, Big Foot, and New Dump Island. The Corps is seeking authorization for placement of beach quality material on all islands except upland diked island H under GC 4105, Activities Involving Control of Effluent Disposal. For all bird nesting disposal islands, the environmental window for placement of dredged material is 1 September – 31 March. For upland diked Island H, the Corps is seeking authorization under GC 4090, Return Water from Upland Contained Disposal Areas. See attached maps for project limits. B.3e. Projects addressed by this PCN will involve maintenance dredging of existing federally authorized navigation channels/borrow areas using hydraulic pipeline dredges and hopper dredges with pump out capability. Depending upon availability of dredge plant, dredges may be either commercial or government owned. The discharge of dredged material will be on CDFs, undiked disposal islands (bird islands), and oceanfront beaches. Material placed on oceanfront beaches and bird islands (via the control-of-effluent method) will be beach quality sand (</= 10% fine-grained sediments; fine-grained defined as less than 0.0625mm in size). Material placed in CDFs will usually contain greater than 10% fine-grained sediments (although in certain situations, beach quality sand may be placed for temporary storage in select CDFs). Each CDF will have one or more dewatering structures (spillways), constructed at a location far away enough from the point of dredge outfall to allow maximum settling of sediments. Each spillway structure is designed to allow surface water to flow into adjacent water bodies in compliance with the State’s turbidity water quality standards (twice daily turbidity reports are required to verify 25 NTUs or less). All work will be performed in compliance with all conditions of applicable permits/authorizations/CAMA consistency concurrences, in addition to all environmental commitments stated in relevant documents prepared by the Wilmington District in compliance with the National Environmental Policy Act (NEPA). 3.5b. USACE submitted PCN application signed and dated May 1, 2008 (and December 16, 2011) requesting use of GCs 3682, 3684, 3698, 3700 and 3703 for the same projects addressed above. March 14, 2012 letter from DWQ provided written approval to utilize said GCs for placement of dredged material on previous disposal sites. Each federally authorized navigation channel/borrow area in North Carolina has been analyzed in compliance with NEPA and has a corresponding Environmental Assessment/Finding of No Significant Impact or Final Environmental Impact Statement. The NC Division of Coastal Management consistency concurrences have been received for all USACE maintenance dredging/borrow projects and corresponding disposal/placement alternatives. Please contact Emily Hughes (910) 251-4635 for a list of these documents or to receive a copy. Many of these projects are maintained at least once every 3 -5 years. Placement/disposal locations for each dredging occurrence may vary but all have been used in the past.
