Mr. Speaker, in response to a) The navy has the following program in place to ensure that emissions from the diesel engines used by the Victoria-class submarines are minimized:
1. Inspections of the Victoria-class submarines are conducted approximately once a year through the marine diesel inspection program. These inspections include electronic engine analysis, to ensure that the engines operate at peak performance and that engine emissions are minimized.
In response to b) "Alternative" fuels have not been considered for submarine use due to their minimal availability and the inherent risk to submarine operations.
Like all Canadian naval vessels, the Victoria-class submarines use a high quality marine diesel fuel that meets the requirements for naval engines and is suitable for interchange with other navies when necessary. In June 2007, Environment Canada regulations came into force reducing the amount of sulphur permissible in marine fuels to 500 parts per million. Fuel procured for the Canadian navy meets this limit, and much of it is far below this limit. It should be noted that the previous specified limit was 5000 parts per million. This change means that emissions of sulphur oxides are now much less.
In response to c) The following projects will ensure that the Victoria-Class submarines’ air conditioning and refrigerant systems are more ozone friendly:
1. The navy will be converting the chilled water system to a more ozone friendly refrigerant, specifically, a gas known as R134a. Since this conversion requires major equipment to be removed from the submarine, it must occur during extended docking work periods. The first vessel to be converted will be HMCS Chicoutimi. The project is expected to cost $5 million for all four submarines.
2. RS-24 is a non-ozone depleting refrigerant blend recently developed as a temporary replacement for R12. Investigations are underway to determine the possibility of using this refrigerant in the submarines as an interim measure to replace R12 while the full conversion project described above is developed and implemented. The expected cost of this project is $200,000 for all four submarines.
3. The Navy is also converting the food refrigerant systems on the Victoria-Class submarines. This conversion will be scheduled during minor maintenance periods and is expected to be complete by 2010. This project is expected to cost $3 million for all four submarines.
In response to d) There is no mandated deadline to replace the fire extinguishing agent halon on the Victoria-class submarines: however, the halon replacement project is expected to be completed by 2012. Under the halon replacement project, halon will be replaced with another fire extinguishing agent on all four submarines by 2012. The estimated cost is approximately $5 million for all four submarines. The mandated deadline for the replacement of R12 refrigerant is 01 Jan 2015; however, the Department of National Defence is working towards having R12 replaced by 01 Jan 2010.
In response to e) In addition to the upgrades mentioned above, under the maritime environmental protection program, the Department of National Defence intends to install oily water separators in order to ensure the oil content of discharged waste water meets the International Maritime Organization regulated limit. The cost of the installations are expected to be approximately $1.5 million for all four submarines.
