n.— «While the U.S. Coast Guard has been given the authority to regulate ballast water discharges through what was originally the Non-Indigenous Aquatic Nuisance Prevention and Control Act of 1990, Cox said the regulatory “scheme” has been ineffective, primarily because of a rule that allows ships to declare that “they have no ballast on board, or commonly referred to as NOBOB ships.» —“Hearing on invasive species focuses on ship’s ballast” by Tom Watts Macomb Daily (Mount Clemens, Mich.) Sept. 10, 2005. (source: Double-Tongued Dictionary)
