Title 33 › CHAPTER 9 — PROTECTION OF NAVIGABLE WATERS AND OF HARBOR AND RIVER IMPROVEMENTS GENERALLY › SUBCHAPTER III — NEW YORK HARBOR, HARBOR OF HAMPTON ROADS, AND HARBOR OF BALTIMORE › § 446
Each harbor supervisor must appoint inspectors and deputy inspectors and give them authority to enforce this subchapter and the Act of August 18, 1894 (28 Stat. 338) and to find and punish people who break those laws. Those officers can arrest people who break these rules, with or without a warrant, but they cannot arrest without a warrant unless the crime happens in their presence. Anyone arrested must be taken right away before a U.S. magistrate, judge, or court. They can board and seize scows or towboats illegally dumping or moving banned material under sections 443–448 and hold the vessels until a court orders their release. They may detain witnesses to dumping (who can be freed on bond), follow towboats towing prohibited loads to the dumping site, and enter gas, oil, and other factories to check for harmful discharges into tidal waters if there is good reason to believe section 441 is being violated.
