Title 33 › CHAPTER 36 — WATER RESOURCES DEVELOPMENT › SUBCHAPTER II — HARBOR DEVELOPMENT › § 2241
Defines key words used in this part about harbors and their upkeep. Deep-draft harbor: a harbor allowed to be built more than 45 feet deep, except projects covered by section 202. Eligible operations and maintenance: federal work to keep harbors working, such as repairs, maintenance dredging to keep width and nominal depth, building and running dredged-material disposal sites, removing contaminated sediments, and fixing harms caused by federal navigation work; for the Saint Lawrence Seaway it means similar upkeep needed to keep it in operation and in reasonable repair. Eligible operations and maintenance do not include buying lands, easements, rights-of-way, or doing required relocations. General cargo harbor: a harbor covered by section 202 or any harbor allowed to be built deeper than 20 feet but not more than 45 feet. Harbor: any U.S. channel or harbor that can carry commercial cargo by commercial ships, but not inland harbors, the Saint Lawrence Seaway, local access or berthing channels, channels or harbors built or kept by nonpublic parties, or parts of the Columbia River upstream of Bonneville lock and dam. Inland harbor: a navigation project mainly used by commercial vessels for inland water cargo, but not projects on the Great Lakes, not tidal projects, not projects authorized deeper than 20 feet, not local access or berthing channels, and not projects built or kept by nonpublic parties. Nominal depth: the official stated depth for a navigation project, including any extra depth that must be kept so ships can pass safely at mean low tide. Non-Federal interest: has the meaning in 42 U.S.C. 1962d–5b and includes interstate agencies and port authorities set up by compacts between states with Congress’s approval. United States: all areas within U.S. territorial boundaries, including the several States, the District of Columbia, the Commonwealth of 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.
