Deck runoff.

(a) Flight deck washdowns are prohibited.

(b) Minimize deck washdowns while in port and in federally-protected waters.

(c) Prior to performing a deck washdown, exposed decks must be broom cleaned and on-deck debris, garbage, paint chips, residues, and spills must be removed, collected, and disposed of onshore in accordance with any applicable solid waste or hazardous substance management and disposal requirements.

(d) If a deck washdown or above water line hull cleaning will result in a discharge, it must be conducted with minimally-toxic and phosphate-free soaps, cleaners, and detergents. The use of soaps that are labeled toxic is prohibited. Furthermore, soaps, cleaners, and detergents should not be caustic and must be biodegradable. All soaps and cleaners must be used as directed by the label.

(e) Where feasible, machinery on deck must have coamings or drip pans, where necessary, to prevent spills and collect any oily discharge that may leak from machinery. The drip pans must be drained to a waste container for disposal onshore in accordance with any applicable oil and hazardous substance management and disposal requirements. The presence of floating solids, visible foam, halogenated phenol compounds, dispersants, and surfactants in deck washdowns must be minimized.

(f) Topside surfaces and other above water line portions of the vessel must be well maintained to minimize the discharge of rust (and other corrosion by-products), cleaning compounds, paint chips, non-skid material fragments, and other materials associated with exterior topside surface preservation. Residual paint droplets entering the water must be minimized when conducting maintenance painting. The discharge of unused paint is prohibited. Paint chips and unused paint residues must be collected and disposed of onshore in accordance with any applicable solid waste and hazardous substance management and disposal requirements.

(g) When vessels conduct underway fuel replenishment, scuppers must be plugged to prevent the discharge of oil. Any oil spilled must be cleaned, managed, and disposed of onshore in accordance with any applicable oil and hazardous substance management and disposal requirements.
