Long-Term Management Strategy for Dredged Material Disposal for Naval Facilities at Pearl Harbor, Hawaii
Abstract
The Naval Station (NAVSTA), Pearl Harbor, dredges a number of locations throughout the Pearl Harbor Naval Complex (PHNC) intermittently to maintain harbor operations. Up to the present time of all of the dredged material has been disposed in the ocean. Recent testing of some sediments has indicated that some of the material is unsuitable for ocean disposal because of potential impacts from contaminants present in the sediments. This finding necessitates evaluating other disposal alternatives that are practicable, economical, and environmentally sound and have high public acceptance. These alternatives should provide disposal solutions for the next 30 years and maintain the future viability of naval operations at Pearl Harbor. Investigations of alternatives require development of a long-term management strategy (LTMS) and evaluation of the environmental effects of various disposal alternatives. This report documents Phase I of a three-phase study to develop a workable LTMS for PHNC. This report includes a review of dredging volumes and frequencies; dredging and disposal equipment and techniques; environmental resources; and capacities, costs, and logistics of potential disposal alternatives. Ten disposal alternatives, including contained aquatic disposal, upland or nearshore confined disposal, and beneficial uses alternatives, are identified for material that is unsuitable for ocean disposal. A screening evaluation of the alternatives was performed to rank the alternatives. Based on the results of this Phase I effort, it is recommended that Phase II be initiated to evaluate the Waipio Peninsula and the Reef Runway disposal alternatives.
