Terms, Abbreviations, and Acronyms for Ocean Ranger Program
15 PPM Alarm: An alarm that activates when the effluent passing though oilfiltering
equipment exceeds 15 parts per million (ppm) of oil.
Agent: Vessel representative hired by the ship's owners. Ship's agent may be
tasked with various jobs such as: ensuring proper vessel documentation and
compliance.
Alaska Waters: For wastewater from large cruise ships means all waters within
the boundaries of the state together with all of the waters of the Alexander
Archipelago even if not within the boundaries of the state.
Alexander Archipelago Waters: These are the “inside waters” of Southeast
Alaska, even when more than 3 nm from land. Please see the list in the General
Permit or statutes for a complete description of boundaries.
Automatic Stopping Device: Is a control mechanism that ensures discharge of
an oily water separator is stopped when the oil content of the effluent exceeds 15
parts per million (PPM). The automatic stopping device may be initiated by the
operation of the oil content meter.
AWTS: Advanced Wastewater Treatment System. A wastewater treatment
system designed to treat wastewater to both MSD and secondary treatment
standards. The secondary treatment standards require a higher removal of solids
and nutrients (as measured by BOD) than a basic MSD. Most AWTS systems
contain mechanical separation of solids by filtering or settling, a biological
process to digest organic wastes, and a UV or ozone system to kill bacteria
without using chlorine.
Bacteria: (Singular: bacterium) Microscopic living organisms that can aid in
pollution control by metabolizing organic matter in sewage, oil spills or other
pollutants. However, bacteria in soil, water or air can also cause human, animal
and plant health problems.
Ballast: Used to improve the stability and control the draft of a ship.
BAT: Best Available Technology. The best available economically achievable
performance for control of pollutants. This can include changes to process
operations and internal controls.
Black Oil: A viscous and black or very dark brown colored oil. Depending on the
quantity spilled, oil tends to quickly spread out over the water surface to a
thickness of about one-millimeter.
