Pierre River Mine Project

GENERAL AENV SIRS 1 – 5
Question No. 5
Request Volume 2, SIR 13, Revised Table 13-1, Page 15-4.
Section 10.1
This table provides comments on the updated Waste Disposal Methods for the
Pierre River Expansion Site. Two items in particular are proposed to be
disposed of at the Regional Municipality of Wood Buffalo sewage lagoon
facilities namely, filtered sewage cake and bar screenings. The address provided
was the Regional Municipality of Wood Buffalo’s civic address. The Regional
Municipality must be consulted for this service and there is no indication that
this has been done.
5a Provide confirmation from the Regional Municipality that they have been
appropriately consulted regarding this specific question and that this is an
acceptable practice and an acceptable solution for disposing of filtered sewage
cake and bar screenings generated by the Project.
Response 5a Personnel from the Fort McMurray Wastewater Facility, the new facility to
replace the current sewage lagoon, confirmed acceptance of current and future
sludge material from Shell’s facilities. They also confirmed that bar screenings
would be better-suited for disposal in a landfill. Therefore, bar screenings will be
placed in the on-site Class II Landfill.
Table 4-2 of the May 2009 Pierre River Mine, Supplemental Information,
Volume 1, has been updated with the new bar screening disposal method or
location. The revised table is reproduced here as Table AENV 5-1.
