When more than 12 nautical miles from the nearest land, any discharge of oil or oily mixtures into the sea from 

 a ship subject to APPS other than an oil tanker or from machinery space bilges of an oil tanker subject to APPS 

 is prohibited except when: 1) the oil or oily mixture does not originate from cargo pump room bilges; 2) the oil 

 or oily mixture is not mixed with oil cargo residues; 3) the ship is not within a Special Area (the study area is 

 not a Special Area for purposes of APPS); 4) the ship is proceeding en route; 5) the oil content of the effluent 

 without dilution is less than 100 parts per million (ppm); and 6) the ship has in operation oily- water separating 

 equipment, a bilge monitor, bilge alarm or combination thereof. 33 CFR 151.10(a). 



The restrictions on discharges 12 nautical miles or less from the nearest land are more stringent. When within 

 12 nautical miles of the nearest land, any discharge of oil or oily mixtures into the sea from a ship other than 

 an oil tanker or from machinery space bilges of an oil tanker is prohibited except when: 1) the oil or oily mixture 

 does not originate from cargo pump room bilges; 2) the oil or oily mixture is not mixed with oU cargo residues; 

 3) the oil content of the effluent without dilution does not exceed 15 ppm; 4) the ship has in operation oily-water 

 separating equipment, a bilge monitor, bilge alarm, or combination thereof; and 5) the oily-water separating 

 equipment is equipped with a 15 ppm bilge alarm. NOTE: In the navigable waters of the U.S., the CWA, section 

 311(b)(3) and 40 CFR 110 govern all discharges of oil and oily mbrtures. 33 CFR 151.10(b). 



A tank vessel subject to APPS may not discharge an oily mixture into the sea from a cargo tank, slop tank or 

 cargo pump bilge unless the vessel: 1) is more than 50 nautical miles from the nearest land; 2) is proceeding en 

 route; 3) is discharging at an instantaneous rate of oil content not exceeding 60 hters per nautical mile; 4) is an 

 existing vessel and the total quantity of oil discharged into the sea does not exceed 1/15000 of the total quantity 

 of the cargo that the discharge formed a part (1/30000 for new vessels); 5) discharges, with certain exceptions, 

 through the above waterline discharge point; 6) has in operation a cargo monitor and control system that is 

 designed for use with the oily mixture being discharged; and 7) is outside the Special Areas. 

 33 CFR 157.37. 



APPS is amended by the Marine Plastic Pollution Research and Control Act of 1987 (MPPRCA), which 

 implements Annex V of MARPOL 73/78 in the U.S. The MPPRCA and implementing regulations at 33 CFR 

 151.51 to 151.77 apply to U.S. Ships (except warships and ships owned or operated by the U.S.) everywhere, 

 including recreational vessels, and to other ships subject to MARPOL 73/78 while in the navigable waters or the 

 Exclusive Economic Zone of the U.S. They prohibit the discharge of plastic or garbage mixed with plastic into 

 any waters and the discharge of dunnage, hning and packing materials that float within 25 nautical miles of the 

 nearest land. Other unground garbage may be discharged beyond 12 nautical miles from the nearest land. Other 

 garbage ground to less than one inch may be discharged beyond three nautical miles of the nearest land. Fixed 

 and floating platforms and associated vessels are subject to more stringent restrictions. "Garbage" is defined as 

 all kinds of victual, domestic and operational waste, excluding fresh fish and parts thereof, generated during the 

 normal operations of the ship and Uable to be disposed of continuously or periodically except dishwater, 

 graywater and certain substances. 33 CFR 151.05. 



Oil Pollution Act of 1990 (OPA) (P.L. 101-380, 33 USC 2701 et seg.) 



The Oil Pollution Act of 1990 (OPA) creates a comprehensive prevention, response, Uability, and compensation 

 regime for dealing with vessel and faciUty-caused oil pollution. The OPA provides for environmental safegu2irds 

 in oil transportation greater than those existing before its passage by: setting new standards for vessel 

 construction, crew licensing, and manning; providing for better contingency planning; enhancing Federal response 

 capabiUty; broadening enforcement authority; increasing penalties; and authorizing multi-agency research and 

 development. A one biUion dollar trust fund is available to cover clean-up costs and damages not compensated 

 by the spiller. 



Title I creates a Uabihty and compensation regime for tank vessel and facihty-source oil pollution. Any party
