Furthermore, since the Coast Guard is responsible for marking obstructions to navigation, Coast Guard officials are concerned that when an offshore platform has been negligently maintained, when the platform operator's identity is ambiguous, or when the operator is no longer financially able or willing to maintain navigation aids on structures, the Coast Guard will inherit these responsibilities by default. In their view, these eventualities, and See Coast Guard response to Federal Regi ster (49FR44924, 13 November 1984~.

The committee, therefore, considers the entire North American littoral as a potential submarine operating area.

Maintaining structures simply as sites for navigational aids is not cost-effective. Another concern, arguing for platform removal, is that a dense population of offshore platforms, which would be more likely if obsolete platforms were not removed, reduces the Coast Guard's flexibility for realigning traffic control schemes to address future developments.

The total worker safety risks will vary directly with the number of individual worker actions, the time necessary to carry them out, and the water depth at which they occur. Thus, the safety risks will be greater for dismantling and removing a large complex structure in deep water that cannot be removed as a single unit and for full removal of such a structure as compared to partial removal.
