EPEA APPROVALS AENV SIRS 90 – 96
94a What other reclamation activities occur after end of mine life (2039)?
Section 15.1
Response 94a The following reclamation activities will follow applicable regulatory guidelines,
approval conditions and approved reclamation plans:
1. Facility decommissioning (e.g. plant site, camp areas, ancillary facilities).
2. Recontouring landforms to maintain or create drainage, as outlined in the
Closure Drainage Plan. This includes constructing the end pit lakes, final
drainage channels, constructed wetlands, and outlet and inlet structures as
required. Some recontouring of terrestrial areas may be required to respond
to settlement of tailings materials, and to create appropriate slopes and
aspects to achieve land capability objectives.
3. Placement of suitable capping material (e.g., overburden), if required.
4. Reclamation material placement on the recontoured areas.
5. Revegetation of remaining landforms to target ecosites.
6. The continuation of monitoring programs (water quality, soil, vegetation,
wildlife, biodiversity), as necessary.
7. Applying for Reclamation Certification of reclaimed areas.
Request 94b How many years of reclamation work will need to occur after end of mine life?
Response 94b Shell estimates that the reclamation activities described in the response to AENV
SIR 94a will take approximately 10 years, except for monitoring and certification
activities that will take place over a period negotiated with Alberta Environment.
Request 94c At what year will Figure 29 of Volume 5 (final closure plan) be complete?
Response 94c Shell estimates that Figure 29 will represent the year 2049.
Question No. 95
Request Volume 2, SIR 402b, Page 23-18.
Shell provides a list of opportunities for progressive reclamation, including the
construction of overburden dumps from the outside to the middle to allow
reclamation of the outermost areas first. The response to SIR 402c and Figure
402-2 indicates no reclamation will occur until 2031, when the dykes of the
external tailings disposal area will occur (8 years prior to end of mine life). The
