Sec.  1700.4  Discharges requiring control.





    For the following discharges incidental to the normal operation of 

Armed Forces vessels, the Administrator and the Secretary have 

determined that it is reasonable and practicable to require use of a 

Marine Pollution Control Device for at least one class of vessel to 

mitigate adverse impacts on the marine environment:

    (a) Aqueous Film-Forming Foam: the firefighting foam and seawater 

mixture discharged during training, testing, or maintenance operations.

    (b) Catapult Water Brake Tank & Post-Launch Retraction Exhaust: the 

oily water skimmed from the water tank used to stop the forward motion 

of an aircraft carrier catapult, and the condensed steam discharged when 

the catapult is retracted.

    (c) Chain Locker Effluent: the accumulated precipitation and 

seawater that is emptied from the compartment used to store the vessel's 

anchor chain.

    (d) Clean Ballast: the seawater taken into, and discharged from, 

dedicated ballast tanks to maintain the stability of the vessel and to 

adjust the buoyancy of submarines.

    (e) Compensated Fuel Ballast: the seawater taken into, and 

discharged from, ballast tanks designed to hold both ballast water and 

fuel to maintain the stability of the vessel.

    (f) Controllable Pitch Propeller Hydraulic Fluid: the hydraulic 

fluid that discharges into the surrounding seawater from propeller seals 

as part of normal operation, and the hydraulic fluid released during 

routine maintenance of the propellers.

    (g) Deck Runoff: the precipitation, washdowns, and seawater falling 

on the weather deck of a vessel and discharged overboard through deck 

openings.

    (h) Dirty Ballast: the seawater taken into, and discharged from, 

empty fuel tanks to maintain the stability of the vessel.

    (i) Distillation and Reverse Osmosis Brine: the concentrated 

seawater (brine) produced as a byproduct of the processes used to 

generate freshwater from seawater.

    (j) Elevator Pit Effluent: the liquid that accumulates in, and is 

discharged from, the sumps of elevator wells on vessels.

    (k) Firemain Systems: the seawater pumped through the firemain 

system for firemain testing, maintenance, and training, and to supply 

water for the operation of certain vessel systems.

    (l) Gas Turbine Water Wash: the water released from washing gas 

turbine components.

    (m) Graywater: galley, bath, and shower water, as well as wastewater 

from lavatory sinks, laundry, interior deck drains, water fountains, and 

shop sinks.

    (n) Hull Coating Leachate: the constituents that leach, dissolve, 

ablate, or erode from the paint on the hull into the surrounding 

seawater.

    (o) Motor Gasoline and Compensating Discharge: the seawater taken 

into, and discharged from, motor gasoline tanks to eliminate free space 

where vapors could accumulate.

    (p) Non-Oily machinery wastewater: the combined wastewater from the 

operation of distilling plants, water chillers, valve packings, water 

piping, low- and high-pressure air compressors, and propulsion engine 

jacket coolers.

    (q) Photographic Laboratory Drains: the laboratory wastewater 

resulting from processing of photographic film.

    (r) Seawater Cooling Overboard Discharge: the discharge of seawater 

from a dedicated system that provides noncontact cooling water for other 

vessel systems.

    (s) Seawater Piping Biofouling Prevention: the discharge of seawater 

containing additives used to prevent the growth and attachment of 

biofouling organisms in dedicated seawater cooling systems on selected 

vessels.

    (t) Small Boat Engine Wet Exhaust: the seawater that is mixed and 

discharged with small boat propulsion engine exhaust to cool the exhaust 

and quiet the engine.

    (u) Sonar Dome Discharge: the leaching of antifoulant materials into 

the surrounding seawater and the release of seawater or freshwater 

retained within the sonar dome.

    (v) Submarine Bilgewater: the wastewater from a variety of sources 

that accumulates in the lowest part of the submarine (i.e., bilge).

    (w) Surface Vessel Bilgewater/Oil-Water Separator Effluent: the 

wastewater from a variety of sources that accumulates in the lowest part 

of the vessel (the bilge), and the effluent produced when the wastewater 

is processed by an oil water separator.

    (x) Underwater Ship Husbandry: the materials discharged during the 

inspection, maintenance, cleaning, and repair of hulls performed while 

the vessel is waterborne.

    (y) Welldeck Discharges: the water that accumulates from seawater 

flooding of the docking well (welldeck) of a vessel used to transport, 

load, and unload amphibious vessels, and from maintenance and freshwater 

washings of the welldeck and equipment and vessels stored in the 

welldeck.
