Dunn, Coastal Coordinator Habitat Conservation Division DATE: March 9, 2017 SUBJECT: Public Notice for Village of Bald Head Island, Frying Pan Shoals Project, Brunswick County, North Carolina. SAW -2012-00040 Biologists with the North Carolina Wildlife Resources Commission (NCWRC) reviewed the public notice with regard to impacts on fish and wildlife resources. 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 U.S.C. 661 et seq.). The Village of Bald Head Island is proposing to perform groin fillet maintenance and beach nourishment along the shoreline of Bald Head Island, including West Beach and South Beach, with material dredged from Frying Pan Shoals. This site proposal would be for the current request as well as future nourishment events. An approximate 460 -acre source site has been identified on the western side of Frying Pan Shoals, approximately I mile offshore of Bald Head Island. Sediment identified would be excavated by cutter head dredge and pumped to shore, providing an overall site capacity of 5.2 million cubic yards. Within this borrow area is a 9.73 exclusion zone to address historic properties / cultural resources. Physical monitoring of the dredge borrow site would be monitored immediately after construction, annually for three years, and biennially afterward. The footprint of each monitoring survey would include the entire permitted site as well as the area of excavation within and any changes in morphology to the Frying Pan Shoals formation. This current proposal is stated to be phase two of the terminal groin installation project. Although we understand that the initial proposal included nourishment to accompany the groin, information should be Mailing Address: Habitat Conservation • 1721 Mail Service Center • Raleigh, NC 27699-1721 Telephone: (919) 707-0220 • Fax: (919) 707-0028 Bald Head Island, Frying Pan Shoals Page 2 March 9, 2017 provided to show the need for the nourishment after structure construction. It may be that the structure has not been in place long enough to accurately model sediment transport and need for nourishment. This is of importance due to environmental impacts to the sediment borrow source and oceanfront beaches during nourishment activities. Frying Pan Shoals provides important marine fishery habitat. Removal of material from this area may alter these habitat areas significantly. Although the NCWRC generally voices concern with impacts to more anadromous, estuarine, and inland fish species, we strongly encourage the applicant and permitting agencies to coordinate with and incorporate concerns and management practices recommended by state and federal marine resource agencies. Independent of source material location and sediment compatibility, projects that affect oceanfront beaches and natural inlet processes such as beach nourishment, inlet dredging, inlet relocation and the construction of hardened structures on or along beaches may adversely affect nesting sea turtles and shorebird foraging and nesting areas. Due to the scope of this project and the documented use of the beaches by sea turtles and shorebirds, the NCWRC has the following comments and recommendations: — The NCWRC has an established sea turtle nesting moratorium that reduces the potential for unintended impacts to nesting sea turtle species that frequent the coast of North Carolina. To avoid impacts to these species, all work on the oceanfront shoreline, including mobilization and demobilization for all beach nourishment events should be conducted outside of the sea turtle nesting season which runs from May 1 until November 15, or until the last known sea turtle nest has hatched. — Oceanfront beaches on Bald Head Island provide suitable nesting, foraging and roosting areas for multiple shorebird species. Nesting birds are sensitive to increased human activity and other disturbances around their nesting areas. To limit unintended impacts to nesting bird species in and near the project area, all work should adhere to the shorebird nesting period from April 1 until August 31. — Survey and monitoring reports should be provided to the appropriate parties in a timely manner and consultation should be done with regulatory and resources agencies prior to ceasing or changing any survey or monitoring activity. — As stated in our comments provided during the review of the terminal groin application, regular nourishment events could potentially impact benthic invertebrate populations Benthic invertebrates are an important food source for foraging birds, both resident and migratory, during both the breeding and nonbreeding seasons. Regular beach nourishment events, such as every five years, can reduce benthic populations when populations are not given appropriate time for recovery.
