1. Sewage treatment
Sewage treatment systems and holding tanks must have adequate capacity. All sewage discharges ashore or at sea must be documented as to date, location, and quantity.

2. Oxides of nitrogen (NOx)
· For engines over 130 kW (175 hp), either comply with emission limits specified in MARPOL Annex VI or develop an appropriate emission reduction plan.
· Develop and implement procedures for use and maintenance of equipment required for emission control, such as catalytic converters.

3. Garbage handling and disposal
Develop procedures for collection, segregation, processing, and disposal, including the use of compactors, incinerators, or other devices. Impose compliance with the incineration requirements set forth in MARPOL, Annex VI, limiting airborne emissions.

4. Ballast water
Mandates precautionary measures to minimize translocation of non-native organisms in ballast water.

5. Hull antifouling systems
Sets allowable leaching rate of anti-fouling systems containing tributyltin (TBT) until January 2008, and prohibits application of TBT after January 2003.

6. Oil pollution prevention
· Require compliance with MARPOL, Annex I, Regulations for the Prevention of Pollution by Oil, which prohibits the discharge of oil or oily waste (including oily bilge or ballast water).
· Develop and implement procedures for handling all oil and oily waste, including loading, storage, and transfer as well as recovery of any oil spilled on deck.

7. Refrigeration systems
· Prohibit the use of refrigerants known to harm the environment, in accordance with the Montreal Protocol on Substances that Deplete the Ozone Layer.
· Develop procedures to control the loss, leakage, venting, and disposal of all refrigerants. (By taking the position that leakage of any refrigerant is potentially harmful, LR is actually more stringent than the Montreal Protocol.)

8. Oxides of sulfur (SOx)
· Limit the sulfur content of oil fuels used onboard, consistent with the quality of fuel available in the area of operation.
· Develop an oil-fuel management system, to include testing and documenting the sulfur content of fuel taken aboard.

9. Firefighting  systems
Prohibit the use of halon or halo-carbons.
