The United States Coast Guard today issued proposed rules that revise several elements of U.S. marine pollution prevention regulations for vessels. Comments from the interested public must be filed not later than 10 October 2000.

Many of the proposals are intended to reconcile U. S. requirements with prevailing international standards on the same subjects.  Interested members are encouraged to review the changes in detail and to convey comments to  or in Washington.  A simplified summary of the changes follows: 

1.      Maximum Permissible Rate of Discharge.   The proposal reduces the maximum allowable rate of discharge of oil and oily mixtures from cargo and slop tanks and bilges from 60 litres/nm to 30 litres/nm. 

2.      Maximum Permissible Oil Content of Effluent.  Proposes to conform U. S. regulations governing oil content of effluent from tanker bilges to MARPOL 73/78 allowance of 15 ppm. 

3.      Automatic Cut-Off Equipment for Certain Vessels.  Proposes to conform U.S. requirements to MARPOL 73/78 standards automatic cut-off devices for effluent that exceeds 15ppm on vessels greater than 10,000 grt (and vessels over 400 grt that do not have segregated ballast tanks. 

4.      Alarms, Filters, and Automatic Stop Devices.  U.S. regulations proposed to be revised to conform to MARPOL 73/78 requirements for pre-6 July 1993-delivered vessels. 

5.      Maximum Term of IOPP Certificates.  Proposes to change to 5 years the term of IOPP Certificates for U.S.-inspected vessels to conform to IMO’s Harmonised System of Surveys and Certification and to reflect changes in the inspection cycle for U.S. Certificates of Inspection (COIs).  

6.      Damage Stability for Tank Vessels.  Proposes new raking damage assumptions for double hull tank vessels over 20,000 dwt. 

7.      Intact Stability Design Requirements.  Proposes amendment of U.S. regulations to conform intact stability design standards to MARPOL requirements intended to reduce lolling during simultaneous ballast and cargo operations. 

8.      Garbage Disposal Records.  Proposes to revise U.S. regulations to conform to MARPOL 73/78 requirement of garbage disposal records for vessels of 400 grt and above.  

9.      Reception Facility Placards at Ports and Terminals.  Proposes a placard requirement that would guide users to U.S. Coast Guard Captain of the Port in order to report insufficiencies at reception facilities. 

10.   Dispensation for Certain U.S.-Flag Ships from Requirement of Shore Connections That Meet International Standards.  Current U.S. regulations required U.S. vessels to employ fittings that meet international standards when discharging oily mixtures to shoreside reception facilities.  These sections are revised to permit smaller vessels whose service is confined to U.S. domestic trades to use connections that are compatible with U.S. reception facilities.  

11.   Definitional Changes.  The proposal adds or refines existing definitions of a number of terms including “oil”, petroleum oil”, “oily mixtures”, “fuel oil”, “oily rags”, and “cargo oil residue”. 

The foregoing summary is quite general and should be used only as a notice of the subject matters addressed.  The text of the proposal appears at 65 Federal Register, No. 153 at pages 48548 through 48564 (August 8, 1948).  Copies of the proposal rules have been forwarded to the Intertanko Safety, Technical and Environmental Committee (ISTEC) for evaluation. Additional copies can be obtained from Jonathan Benner by inquiry to him in Washington, D.C. at +1 202.659.6656 or
