Cleaning the house is what people do to remove clutter, garbage and dirt from where they live and put things where they belong to make the house look tidy. Air-dried coating means a coating that dries using air or forced hot air at temperatures up to 1940° F (900° C). Clean ballast means the ballast of a tank that, since the last time oil was transported in it, has been cleaned in such a way that the effluent from the tank, if discharged from a ship that is parked in clean and calm waters on a clear day, would not produce visible traces of oil on the surface of the water or in the adjacent shores. or cause a sludge or emulsion to be deposited beneath the surface of the water or on adjacent shores.
If the ballast is discharged through an oil discharge monitoring and control system approved by the Administration, tests based on that system to the effect that the oil content of the effluent did not exceed 15 parts per million will determine that the ballast was clean, despite the presence of visible traces. Cleaning the house can consist of sweeping the floor with a broom, cleaning carpets with a vacuum, cleaning clothes and storing them, and washing windows.
