This community information site has been established to provide timely and relevant information following a breach of a containment pond at the Obed Mountain Mine.
- Remediation activity has commenced along the Apetowun Creek, where solids are being recovered with excavators and trucks. Ongoing sampling is being conducted to track clean-up progress on sediment deposited by the release.
- Newly designed sediment traps have been installed adjacent to the Apetowun Creek and a new silt fence has been installed where the Plante Creek enters the Athabasca River.
- Clearing efforts are ongoing to prepare access to work sites at approved locations along the creeks. Activities are focused on stripping and stockpiling the cover soil, and installing mulch and swamp matting to stabilize these areas for crews and equipment.
- As surveys of the creeks continue, additional approval applications are being prepared and submitted for access to other sites.
- Remediation work is also underway on areas around the creeks. This includes bank re-sloping, and applying rip-rap material and erosion control measures in vulnerable areas. In addition, repairs are being carried out on affected culverts and the designs have been enhanced from the original installations to provide for fish passage.
- Approvals needed under the Water Act for remediation activities have been granted to allow for further work.
- Third-party specialists recently completed a second series of soil and sediment tests around the mine site and creek area. The test results and a summary of the findings are posted on under the “Data” tab at www.obed.ca.
- Company representatives participated in a public forum held with First Nations, Métis, government representatives, scientists and the general public at the University of Alberta on February 27, 2014. The purpose of the forum was to share the findings of an independent scientific review of the Obed Mountain Mine remediation plans. The review was conducted by leading water scientists engaged by ESRD through the University of Alberta Water Initiative.
- Independent experts are conducting a comprehensive review of the water quality, soil and sediment data for the current monitoring program.
- A site tour was recently conducted for representatives of the University of Alberta and Alberta Environment and Sustainable Resource Development (AESRD).
- Activities continue in preparation for winter remediation work, and certain approvals have been granted for locations along the Plante and Apetowun Creeks. Winter field work is anticipated to commence shortly, with a focus on recovering sediment and constructing sediment traps, in advance of spring run-off.
- Reconstruction of an erosion channel created by the release is completed. This effort involved re-sloping and stabilizing the earth, and installing rock checks for sediment control.
- An additional sediment sampling program along the Apetowun Creek was conducted, and the samples are currently being analyzed by a third-party laboratory.
- Feedback has been provided by AESRD on certain plans submitted under the Environmental Protection Order. This feedback will be incorporated into the final versions for approval, and dialogue on planning continues with AESRD.
