Morehead City Harbor is a federal navigation waterway in Morehead City in southeastern North Carolina, approximately 3 miles from the Atlantic Ocean through Beaufort Inlet. ANAMAR was contracted by USACE Wilmington District to perform an MPRSA Section 103 Tier I sediment evaluation for the North Carolina State Ports Authority facilities and portions of the inner and outer harbor, and a Tier III sampling and analysis report and sediment evaluation for other portions of the outer harbor and U.S. Coast Guard Station Fort Macon. The project purpose is to maintain navigation efficiency and safety within Morehead City Harbor. ANAMAR provided all necessary information to determine the suitability of dredged material for ocean disposal at the Morehead City ODMDS.
Areas to be dredged were divided into six project-specific dredging units (DUs), with four associated with the Tier I analysis and two associated with the Tier III analysis. Each DU represented defined associated basins, channel reaches, or ranges based on expected sediment characteristics. Field sampling for the Tier III analysis was conducted in April 2017 and involved collection of vibracore and grab sediment samples and site water. ANAMAR coordinated and directed field operations and worked closely with USACE and EPA to design sampling and analysis schemes, collect samples, and subcontract coring services and laboratory analysis. ANAMAR reviewed all data and produced a Tier I evaluation and Tier III testing report summarizing the analytical results, along with a sediment evaluation for use by USACE in obtaining concurrence from EPA.
