Lillian Borrone comments present the perspective of the Port Authority of New York and New Jersey on the National Research Council (NRC) report "Contaminated Marine Sediments in Ports and Waterways: Cleanup Strategies and Technologies" (March 1997). The NRC report is seen as an important step forward, because it gives the opportunity to reach resolution on strategies that have been talked about for a while in a piecemeal fashion. The report clearly and thoughtfully explains that treating dredged material as a resource can occur only when regulatory uncertainties are addressed and adequate public/private partnerships are developed. Richard Schwer comments present the perspective of the chemical industry on the National Research Council (NRC) report "Contaminated Marine Sediments in Ports and Waterways: Cleanup Strategies and Technologies" (March 1997). The chemical industry is supportive of the approaches taken by the NRC report and thinks that it points in the right direction, and that its systematic process for evaluating and addressing sediment problems will lead to sound management decisions. The comments by CL Missimer present the forest products industry perspective on the National Research Council (NRC) report "Contaminated Marine Sediments in Ports and Waterways: Cleanup Strategies and Technologies" (March 1997). Most of the contaminated sediment sites associated with the forest products industry are located in nonnavigational waters, making the primary objective risk reduction. Several questions are raised on reducing risk and remedial actions, and suggestions are made on how the NRC report could be extended to address these issues. The comments from Paul Ziemkiewicz present the coal industry perspective on the National Research Council (NRC) report "Contaminated Marine Sediments in Ports and Waterways: Cleanup Strategies and Technologies" (March 1997). The interest of the coal industry is as a user or recipient of these sediments. The sediments are used for mine grouting and surface applications. The issues with which the industry is concerned are regulatory coherence between federal and state agencies, liability issues, and quality assurance and quality control issues. The comments from Stephen Garbaciak present the inland waterways and lakes perspective on the National Research Council (NRC) report "Contaminated Marine Sediments in Ports and Waterways: Cleanup Strategies and Technologies" (March 1997). The comments concern uncertainty, and its role in a variety of issues related to dealing with contaminated sediments, for both remediation projects and navigational dredging.
