Abstract:

This manual will be used in the implementation of Section 103 of Public Law 92-532, the Marine Protection, Research, and Sanctuaries Act of 1972. Procedures are presented for evaluation of potential environmental impacts of the discharge of dredged material into ocean waters, an evaluation that is required in considering permit applications for the transportation of dredged material for ocean dumping. The manual transmitted herewith represents a multidisciplinary effort of both agencies to develop procedurally sound, routinely implementable guidance for complying with the technical requirements of the Federal Register. The procedures given in the manual are applicable to evaluation of the potential ecological effects of dumping from hopper dredges, barges, and scows. The requirements of the Register are discussed, and detailed guidance is provided on sediment and water sample collection, preparation, and preservation chemical analysis of the liquid phase bioassays of liquid, suspended particulate, and solid phases estimation of bioaccumulation potential and the estimation of initial mixing. The manual is particularly important in forming a foundation to be augmented by more meaningful and comprehensive evaluation procedures and guidelines as these evolve from current and future environmental research.
