 sewage into the sea is prohibited, except when : ' 



(a) the ship is discharging at a distance of more than ^* nautical miles 



from the nearest land, provided that sewage that has been stored in holding 

 tanks shall not be discharged instantaneously but at a moderate rate when the 

 ship is en route and proceeding at not less than 4 knots ; or 



(b) the ship has in operation .suitable .sewage treatnipnt equipment as defined 

 in Regulation 3(5) (a ) which can satisfy tlie following criteria : 



(i)' The total coliform count of the efHuent shall not exceed [10,000] per 

 litre,'" and 



(ii)'' The eflluent shall not produce visible floating solids in, nor cause dis- 

 coloration of, the surrounding water ; or 



(c) the ship is situated in the waters of a State and is discharging .sewage in 

 accordance with such less severe requirements as may be imposed by such State.'"

f"' Onp dplppatlon rtoubted whether^ the pipeline should in all cases be a mandatory re- 

 qiii' ement for the issue of a certificate. 



« One delegation siipKested that consideration should be given to inclusion of special 

 requirements for fixed platforms. 



" Some delepritions sugpested the insertion of the following: words at the besrinninff of 

 this sentence "Without prejudice to mor^ stringent regulations which a coastal State 

 may make [within the limits of national iurisdiction/in respect of areas under Its juris- 

 diction/in respect of waters under its jurisdiction]. 



* No clear majority could he reached with respect to any narticular distance from land. 

 Furthermore, the scientific information available indicated that, in view of the large 

 number of variable factors involved, it would not be possible to establish a pnrtic"lar 

 distance on a scientific basis only. It appears, however, that this would probably fall 

 wit''iii 12 miles from the nearest land. 



» Several delegations were of the opinion that the words "under test conditions" should 

 be inserted at the beginninc of the sub-paragraph. 



'" Some delegations proposed the inclusion of BOD as a criterion. Other delegations felt 

 th-'t the coliform criteria should not he included. 



11 Some delegations were of the opinion that the words "when in operation aboard ship" 

 should be inserted at the heginnine of tlie sub-paragraph. 



12 Some delegations felt that the text of this sub-paragranh might need to be reviewed 

 when the distance from the nearest land in sub-paragraph (a) of this Regulation has been 

 estalilished. Other delegations were of the opinion that this sub-paragraph should be deleted.
