OIL TANKERS 



(1) "^"^ Every oil tanker shall operate under such methods as appropriate to

REGULATION 12. — METHODS FOR THE PREVENTION OF OIL POLLUTION FROM OIL 

 TANKERS WHILE OPERATING IN SPECIAL AREAS 



(1) Special Areas: 



(a) For the purposes of this Annex special areas shall include the Mediter- 

 ranean Sea, Baltic Sea and Black Sea. 



(b) Each Contracting Government of a State, the coastline of which borders 

 on any of the special areas defined in Regulation 1(10) of this Annex, shall take 

 appropriate measures in order to achieve the earliest adoption of the following 

 methods for preventing oil pollution in respect of areas under its jurisdiction "' 



(c) Eh-ery oil tanker while operating in any special area, as defined in Regula- 

 tion 1(10) of this Annex and listed in sub-paragraph (a) of this paragraph, shall 

 be subject to the applicable provisions of this Regulation. 



( 2 ) The Mediterranean Sea : ^ 



The oil pollution prevention by oil tankers in the Mediterranean Sea, recog- 

 nized as a special area, will be effected as follows : 



(a) oil tankers, while operating in the Mediterranean Sea, shall retain on 

 board all oil drainage and sludge, dirty ballast and tank washing waters and, 

 [if proceeding to oil loading terminals, repair ports, and sea water courses with a 

 low depth contour which may require ballast lightening], and shall discharge 

 them only to shore reception facilities to be provided [there], as appropriate, by 

 Contracting Governments. 



— PppendiDff on the decisions by the Conference on Repnlation 9 relating to n possible 

 inclusion of special discharsre criteria for non-persistent oil, this paragraph might require 

 mortification (see Footnote 14 under Regulation 9). 



'^ Several delegations were of the opinion that there should be no mandatory require- 

 ments for segregated ballast tankers and therefore the paragraph should be deleted. 



^•t Some delegations were of the opinion that the dates should be 1 January 1976, 1 .Janu- 

 ary 197R and 1 January 1979 respectively. The United States stated that the dates 

 indicated in the draft would fail to meet the objectives of the Conference decided by the 

 Assembly Resolution A.2.S7(VII) and Recommendation 92 of the Stockholm Conference. 



^ Some delegations suggested the deletion of the words "or the absence of a building 

 contract". 



^ Some delegations suggested that further consideration should be given to the possible 

 inclusion of wording such as "This requirement shall not apply to oil tankers which do 

 not normally carry water ballast in their cargo tanks and which in their particular route 

 and due to their design have the facility to dispose of their dirty ballast, tank washings 

 and slops in accordance with the discharge criteria and those operating in special areas." 



^ It was recognized that the words "under its jurisdiction" were inappropriate and 

 would require revision. In this connexion one delegation suggested the following alter- 

 native wording : 



"(b) Each Contracting Government of a State, the coastline of which borders on any 

 of the special areas defined in Regulation 1(10) of this Annex, shall take appropriate 

 measures within its jurisdiction to achieve the earliest adoption of the following methods 

 for preventing oil pollution." 



28 Some delegations were of the opinion that there should be one single set of require- 

 ments for all the special areas listed in sub-paragraph (1) (a) of this Regulation.
