§ 1700.37 Underwater ship husbandry.

(a) For discharges from vessels that are less than 79 feet in length:

(1) To the greatest extent practicable, vessel hulls with an antifouling hull coating must not be cleaned within 90 days after the antifouling coating application.

(2) Vessel hulls must be inspected, maintained, and cleaned to minimize the removal and discharge of antifouling coatings and the transport of fouling organisms. To the greatest extent practicable, rigorous vessel hull cleanings must take place in drydock or at a land-based facility where the removed fouling organisms or spent antifouling coatings can be disposed of onshore in accordance with any applicable solid waste or hazardous substance management and disposal requirements.
