Reply:As set out in the Minister's Notice of Intent on Cleaner Vehicles, Engines and Fuels, the regulations set a limit of 15 ppm coming into effect in June 1, 2006. This level and timing are required to meet new vehicle emission standards that will be required for the 2007 model year.

Stakeholders representing the fuel industry commented on test methods for sulphur levels to use for compliance and reporting purposes. They also recommended that provisions for alternative test methods be included in the Regulations.

Many parties requested that the regulations include flexibility to allow use of alternative test methods for reporting purposes.

Reply: The final diesel regulations incorporate changes to the test methods:

For reporting purposes only, the regulations also allow ASTM 6428, ASTM 2622, ASTM D 1266 until December 31, 2003. After that date, the approach used in the Benzene in Gasoline Regulations for alternative test methods has been adopted: the final regulations allow use of alternative test methods for reporting purposes, provided that the test method is demonstrated by the regulatee to be equivalent to ASTM D 5453 using the comparison method ASTM D 4855.

Reply: The presence of higher sulphur products and crude in the

distribution system creates the potential for contamination of 15 ppm diesel fuel. In developing its regulations, the EPA examined how pipelines would have to be managed to minimize contamination of low-sulphur diesel fuel. The EPA found that more careful pipeline management, including larger product interface and increased volumes of re-blending contaminated batches would occur, resulting in additional pipeline and distribution system costs.

Canada will face these same types of issues with the introduction of 15 ppm diesel fuel. Natural Resources Canada, in consultation with other federal and provincial government departments and industry, is now considering the structure and terms of reference of a study to investigate the potential constraints of the existing distribution system and the possible effects in terms of distillate supply. The study has not yet been completed.

The EPA has determined that a level of 15 ppm sulphur in diesel fuel will be necessary for new on-road vehicle emission standards to be met. Therefore, the regulations stipulate a sulphur limit of 15 ppm for sales of on-road diesel fuel.

Under the regulations, the 15 ppm limit for sales in the northern supply area comes into effect one year later than in the rest of Canada. The CGSB , Sunoco and Imperial Oil suggested that the definition of "northern supply area" be based on specific geographic boundaries rather than using CAN/CGSB -3.5-99 zones.

Reply: The final diesel regulations have modified the definition of Northern Supply Area so it is based on geographic boundaries. The definition has also been revised to exclude primary roads in the North in order to address concerns expressed about potential misfuelling as discussed below. On this issue, there were subsequent consultations with the CTA, CPPI and the governments of Yukon, Northwest Territories, Quebec and Newfoundland. The resulting definition is a consensus of the above parties. Maps showing the Northern Supply Area are provided in Appendix 1.

Concerns were raised by the CVMA, EMA and the CTA regarding potential misfuelling in the North due to the later effective date for sales in the northern supply region.

Reply: The implementation date for sales in northern regions is September 1, 2007, reflecting fuel distribution and logistical difficulties in northern Canada. To address the concerns raised, the final regulations have modified the definition of Northern Supply Area to exclude Newfoundland and most primary roads in the North. Environment Canada believes that this will mitigate potential need for labelling of high sulphur diesel fuel in the North.

Reply:Potential for misfuelling of diesel on-road vehicles exists presently, as diesel fuel for off-road use can have a sulphur level higher than the existing limit for on-road diesel fuel. This situation will continue to exist when sulphur in on-road diesel fuel is reduced to 15 ppm. With the more stringent 15 ppm limit, there will be a greater risk of contamination from higher sulphur products resulting in the regulated limit being exceeded. As discussed above, this will require more careful pipeline and storage tank management an issue Natural Resources Canada will be studying .

A number of parties commented on the potential use of economic instruments to promote the early introduction of low sulphur on-road diesel fuel.

Reply: Environment Canada has worked with the National Round

Table on the Economy and the Environment (NRTEE), which has explored opportunities to apply fiscal instruments to complement the cleaner vehicles and fuels agenda, including the early introduction of low-sulphur diesel prior to 2006. The Cleaner Transportation Working Group under the NRTEE was not able to reach agreement on a recommendation regarding the use of a tax differential to accelerate the introduction of low-sulphur diesel.

In its final analysis, the Government of Canada determined that Regulations under CEPA are the most appropriate measure.

Reply:Environment Canada' s cost estimate is based on the EPA estimate which is an average cost of vehicles ranging from light heavy-duty trucks to heavy heavy-duty trucks and urban buses. Environment Canada recognizes that cost estimates vary depending on factors such as the cost of the fuel, the distance traveled, size of engine and the fuel consumption rate of the engine. Accordingly, the information provided by the CTA has been added to the RIAS.
