93B Interpretation of this Part

In this Part:

damage to a vessel or its equipment does not include:

(a) deterioration resulting from failure to maintain the vessel or equipment; or
(b) defects that develop during the normal operation of the vessel or equipment.

Grade A treated sewage means sewage that has been treated and complies with the standard set out in Part 2 of Schedule 7 to the Transport Operations (Marine Pollution) Regulation 2008 of Queensland.

Note: The standards for Grade A treated sewage are the implementation of Resolution of MEPC.2(IV) MARPOL 73/78 made for the purposes of Annex IV of MARPOL 73/78.

Grade B treated sewage means sewage that has been treated and complies with the standard set out in Part 3 of Schedule 7 to the Transport Operations (Marine Pollution) Regulation 2008 of Queensland.

Grade C treated sewage means sewage that has been treated and complies with the standard set out in Part 4 of Schedule 7 to the Transport Operations (Marine Pollution) Regulation 2008 of Queensland.

Note: The standards are:

Note: For Grade A treated sewage

Note: Thermotolerant coliforms—the relevant level of the thermotolerant coliform count of the samples of treated sewage taken during the test period must not be more than 250 thermotolerant coliforms/100 mL, most probable number, as determined by a multiple tube fermentation analysis or an equivalent analytical procedure.

Note: Suspended solids—the relevant level of the total suspended solids content of the samples of treated sewage taken during the test period must not be more than 50 mg/L above the suspended solids content of ambient water used for flushing purposes.

Note: Biochemical oxygen demand—the relevant level of the 5 day biochemical oxygen demand of the samples of treated sewage taken during the test period must not be more than 50 mg/L.

Note: For Grade B treated sewage

Note: Thermotolerant coliforms—the relevant level of the thermotolerant coliform count of the samples of treated sewage taken during the test period must not be more than 150 thermotolerant coliforms/100 mL, most probable number, as determined by a multiple tube fermentation analysis or an equivalent analytical procedure.
