Sec.  1700.5  Discharges not 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 not reasonable or practicable to require use of a 

Marine Pollution Control Device to mitigate adverse impacts on the 

marine environment:

    (a) Boiler Blowdown: the water and steam discharged when a steam 

boiler is blown down, or when a steam safety valve is tested.

    (b) Catapult Wet Accumulator Discharge: the water discharged from a 

catapult wet accumulator, which stores a steam/water mixture for 

launching aircraft from an aircraft carrier.

    (c) Cathodic Protection: the constituents released into surrounding 

water from sacrificial anode or impressed

current cathodic hull corrosion protection systems.

    (d) Freshwater Lay-up: the potable water that is discharged from the 

seawater cooling system while the vessel is in port, and the cooling 

system is in lay-up mode (a standby mode where seawater in the system is 

replaced with potable water for corrosion protection).

    (e) Mine Countermeasures Equipment Lubrication: the constituents 

released into the surrounding seawater by erosion or dissolution from 

lubricated mine countermeasures equipment when the equipment is deployed 

and towed.

    (f) Portable Damage Control Drain Pump Discharge: the seawater 

pumped through the portable damage control drain pump and discharged 

overboard during testing, maintenance, and training activities.

    (g) Portable Damage Control Drain Pump Wet Exhaust: the seawater 

mixed and discharged with portable damage control drain pump exhaust to 

cool the exhaust and quiet the engine.

    (h) Refrigeration and Air Conditioning Condensate: the drainage of 

condensed moisture from air conditioning units, refrigerators, freezers, 

and refrigerated spaces.

    (i) Rudder Bearing Lubrication: the oil or grease released by the 

erosion or dissolution from lubricated bearings that support the rudder 

and allow it to turn freely.

    (j) Steam Condensate: the condensed steam discharged from a vessel 

in port, where the steam originates from port facilities.

    (k) Stern Tube Seals and Underwater Bearing Lubrication: the 

seawater pumped through stern tube seals and underwater bearings to 

lubricate and cool them during normal operation.

    (l) Submarine Acoustic Countermeasures Launcher Discharge: the 

seawater that is mixed with acoustic countermeasure device propulsion 

gas following a countermeasure launch that is then exchanged with 

surrounding seawater, or partially drained when the launch assembly is 

removed from the submarine for maintenance.

    (m) Submarine Emergency Diesel Engine Wet Exhaust: the seawater that 

is mixed and discharged with submarine emergency diesel engine exhaust 

to cool the exhaust and quiet the engine.

    (n) Submarine Outboard Equipment Grease and External Hydraulics: the 

grease released into the surrounding seawater by erosion or dissolution 

from submarine equipment exposed to seawater.
