Transport Canada has issued a bulletin on the interim measures regarding compliance with IMO Tier III nitrogen oxides emissions standards set out in the Vessel Pollution and Dangerous Chemicals Regulations highlighting that it will not require compliance with the IMO Tier III NOx emissions standards until January 1, 2017.
In early fall of 2015, marine engine suppliers indicated that engine manufacturers based in the US were not producing IMO Tier III compliant marine diesel engines under 750 kW that would be available by January 1, 2016
This bulletin applies to all ships, installing a small marine diesel engine with a power rating between 130 kilowatts and 750 kilowatts, that are subject to subsection 110.3 (4) of the Regulation.
Interim measures
Transport Canada will not require compliance with the IMO Tier III nitrogen oxides emissions standards set out in subsection 110.3 (4) of the Regulations, until January 1, 2017, IF the marine diesel engine with a power ratings between 130 kilowatts and 750 kilowatts:
- Meets the IMO Tier II nitrogen oxides emissions standards set out in subsection 110.2 (3) of the Regulations;
OR
2. Complies with the United States Environmental Protection Agency Tier 3 emission standards for marine diesel engines set under Title 40, section 1042.101, of the Code of Federal Regulations of the United States for Category 1 engines.
While these interim measures are in place, Transport Canada will analyze issues of the IMO Tier III standards as they apply to:
- the availability of compliant engines;
- current emission abatement technologies; and
- the technical challenges.
This analysis will help make informed decisions in the future, on how best to apply the IMO Tier III standards under the Regulation.
