.2 existing passenger ships, other than those specified in sub-paragraph .3 below, when operating in Baltic Sea Special Area and intending to discharge treated sewage effluent into the sea on or after 1 June 2021; and
.3 1 June 2023 for existing passenger ships en route directly to or from a port located outside Baltic Sea Special Area and to or from a port located east of longitude 28˚10' E within the special area that do not make any other port calls within the special area and intending to discharge treated sewage effluent into the sea."

2 – Definitions

5 Paragraph 2.1 is replaced by the following:

"2.1 Annex IV – the revised Annex IV of the International Convention for the Prevention of Pollution from Ships, 1973, as modified by the 1978 and 1997 Protocols (MARPOL), as amended by resolutions MEPC.115(51), MEPC.200(62) MEPC.216(63), MEPC.246(66), MEPC.265(68) and MEPC.274(69)."

4 – Technical specification

6 Paragraphs 4.4 and 4.5 are deleted.

5 – Testing considerations

7 The last sentence of paragraph 5.4.2 is replaced by the following:

"The forms of the Certificate of Type Approval and its appendix are set out in the annexes 1 and 2 to these Guidelines."

Annex – FORM OF CERTIFICATE OF TYPE APPROVAL FOR SEWAGE TREATMENT PLANTS AND APPENDIX
8	The existing annex is renumbered as annex 1 and the title is replaced with the following:

CIPHER	FOR SEWAGE TREATMENT PLANTS

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.
