AIR ERCB SIRS 40 – 45
Question No. 45
Section 6.1
Request Volume 1, Section 11.1, Page 11-29, Supplemental Information Responses.
Shell states, “As stated in EIA, Volume 3, Air Quality, Noise and Environmental
Health, Section 3.1.5.2, vehicles in the mine fleet will meet applicable emissions
standards at the time of purchase.” Shell used Tier 4 emission standards to
develop a regional emissions profile and this was modeled for the assessment of
predicted acid input (PAI).
45a Does Shell commit to purchasing mine fleet vehicles that meet Tier 4 emission
standards if these standards have not been implemented in Canada at the time of
purchase?
Response 45a As stated in EIA, Volume 3, Section 3.1.5.2, vehicles in the mine fleet will meet
applicable emission standards at the time of purchase. As Tier 4 emission
standards are directed at the equipment manufacturers, they dictate when these
products will become available in the United States and Canada. If Tier 4
emission standards are not adopted in Canada, it is unlikely that manufacturers
will produce Tier 4-compliant product lines solely for US markets. Shell expects
that Tier 4-compliant mobile equipment manufactured for both Canada and the
US will become available in alignment with the timelines set out by the US.
Environmental Protection Agency (US EPA).
Shell will commit to the purchase of Tier 4-compliant equipment only if these
products are made available in both the US and Canada.
Request 45b If not, explain why Shell will not make the commitment.
