Annex 2 - FORM OF CERTIFICATE OF TYPE APPROVAL FOR SEWAGE TREATMENT PLANTS AND APPENDIX (MEETING RESOLUTION MEPC.227(64), EXCEPT FOR PARAGRAPH 4.2 OF THE ANNEX TO THIS RESOLUTION)

This is to certify that the sewage treatment plant, type ............................................................ ,

having a designed hydraulic loading of ............ cubic metres per day, (m³/day), an organic loading of ............ kg per day biochemical oxygen demand without nitrification (BOD₅ without nitrification) and of the design shown on drawings Nos. ..........................................................

manufactured by ......................................................................................................................

has been examined and satisfactorily tested in accordance with the International Maritime Organization resolution MEPC.227(64) (except for paragraph 4.2) to meet the operational requirements referred to in regulations 9.1.1 of MARPOL Annex IV, as amended.

The tests on the sewage treatment plant were carried out

ashore at^footnote ................................................................................................................................

on board at^footnote ..............................................................................................................................

and completed on ....................................................................................................................

The sewage treatment plant was tested and produced an effluent which, on analysis, produces:

• .1 a geometric mean of no more than 100 thermotolerant coliforms/100 ml;

• .2 a geometric mean of total suspended solids of 35 Qi/Qe mg/l if tested ashore or the maximum total suspended solids not exceeding (35 plus x) Qi/Qe mg/l for the ambient water used for flushing purposes if tested on board;

• .3 a geometric mean of 5-day biochemical oxygen demand without nitrification (BOD₅ without nitrification) of no more than 25 Qi/Qe mg/l;

• .4 a geometric mean of chemical oxygen demand (COD) of no more than 125 Qi/Qe mg/l; and

• .5 pH between 6 and 8.5.

The Administration confirms that the sewage treatment plant can operate at angles of inclination of 22.5° in any plane from the normal operating position.

Details of the tests and the results obtained are shown on the appendix to this Certificate.

A plate or durable label containing data of the manufacturer's name, type and serial numbers, hydraulic loading and date of manufacture should be fitted on each sewage treatment plant.

A copy of this certificate should be carried on board any ship equipped with the above described sewage treatment plant.
