Pierre River Mine Project

GENERAL AENV SIRS 1 – 5
Section 10.1
Request 3b Present and discuss options for alternative landfill sites that are located further
from the Athabasca River and which would reduce the potential for
contamination of the river.
Response 3b See the response to AENV SIR 3a.
Request 3c Describe the design features planned for the class II landfills which ensure waste
seepage will not contaminate groundwater and will not reach the Athabasca
River.
Response 3c Basic engineering has not been finalized on these landfills. Therefore, no
information is available on their design features. As stated in the response to
AENV SIR 3a, Shell will adhere to the appropriate Alberta codes and standards
for designing Class II landfills and monitoring for any potential groundwater
contamination.
Question No. 4
Request Volume 1, Section 4, Table 4-2, Page 4-8.
Table 4-2 describes the various waste categories and disposal methods planned
for the Pierre River Mine. One of the waste categories is domestic garbage, food
remnants and food contaminated waste to be deposited in the class II landfill.
4a What design features and mitigation measures will Shell employ to ensure that
the landfills will not attract wildlife? Has Shell considered fencing the landfills
to prevent access by wildlife?
Response 4a A portion of the Class II Landfill will be designated for domestic waste (food
remnants and food-contaminated waste) and will be fenced to prevent wildlife
access.
Request 4b What is meant by the column title ‘storage location’ in Table 4-2? For example,
when ‘bin’ is listed as the storage location, as it is for domestic garbage, does
that mean all domestic garbage will be placed in some sort of vessel, and then
dumped in the landfill? Clarify how waste materials will be handled at the
landfill sites.
Response 4b The storage location refers to how the waste material will be stored or
transported. As in the example, bin refers to the receptacle in which waste
material will be held before being taken to a landfill for final disposal. Waste
material will be handled at Shell’s on-site landfills according to the Code of
Practice for Landfills.
