The EPA/Navy CERCLA Remedial Action Technology Guide is a collection of (1) engineering bulletins produced by EPA's Technical Support Branch in Cincinnati, Ohio, and (2) remedial action technical data sheets produced by the Naval Energy and Environmental Support Activity (NEESA) in Port Hueneme, California. These documents comprehensively summarize the latest information obtainable on many of the best available remedial technologies. The intent is to convey information (based on previous applications) to help RPMs, engineers in charge, on-scene coordinators, Navy resident officers in charge of construction, and contractors decide if a technology should be used at a hazardous waste site and, if so, what are the relevant design, implementation, and cost considerations. Addenda will be issued periodically to update the original bulletins and technical data sheets, and other technologies may be added.
