Summary

Defines key words used in this part of the law. It explains what kinds of harbors and work the rules cover. "Deep-draft harbor" means a harbor approved to be dug deeper than 45 feet, except projects approved under section 202. "Eligible operations and maintenance" means federal work to operate, keep up, repair, or rehab navigation projects, including maintenance dredging to keep width and depth, building and running dredged-material disposal sites, removing contaminated sediments that affect federal channels, and fixing harms caused by federal O&M. For the Saint Lawrence Seaway, it means the same kinds of work needed to keep that Seaway operated and in repair. It does not include buying land, easements, rights-of-way, or doing required relocations. "General cargo harbor" means harbors approved under section 202 and harbors built deeper than 20 feet but not deeper than 45 feet. "Harbor" means any channel or harbor used to move commercial cargo by commercial ships, but it does not include inland harbors, the Saint Lawrence Seaway, local access or berthing channels, channels built or kept by private parties, or any part of the Columbia River except the channels downstream of Bonneville Lock and Dam. "Inland harbor" means a navigation project mainly for commercial vessels on inland waters and does not include Great Lakes projects, tidal projects, projects deeper than 20 feet, local access or berthing channels, or projects built or kept by private parties. "Nominal depth" means the stated project depth, including any extra depth needed so vessels can pass safely at mean low tide. "Non-Federal interest" has the meaning given in 42 U.S.C. 1962d–5b and includes interstate agencies and port authorities set up by compacts between states with Congress’s consent under Article I, section 10 of the Constitution. "United States" includes the several States, the District of Columbia, Puerto Rico, the Virgin Islands, Guam, American Samoa, the Trust Territory of the Pacific Islands, the Northern Mariana Islands, and any other territory or possession under U.S. jurisdiction.
