Sherritt International Corporation responds to charges from Alberta Crown Prosecutor

Sherritt International Corporation (Sherritt), is reviewing the charges related to the Obed Mountain Mine release that were announced today by the Alberta Crown Prosecutor.

Sherritt has worked with provincial and federal regulatory authorities throughout the investigation to ensure all requirements set forth by the Environmental Protection Order (EPO), issued by Alberta Environment and Sustainable Resource Development (AESRD) in November 2013 have been met.

Sherritt sold Coal Valley Resources Inc. (CVRI) and its holdings, including the Obed Mountain Mine, in a transaction finalized in April 2014. As part of this cooperation, Sherritt and CVRI have met all requirements set forth by the EPO, including remediation, sampling and testing. Results from sampling and testing are posted on a weekly and monthly basis on the Obed website.

Sherritt is committed to understanding the circumstances that contributed to the release and working with regulators to take the necessary steps to prevent any recurrence.

Water sampling and monitoring ongoing under summer progam; new reports available on Obed website

  • The Final Impact Report was submitted for approval on May 28th, 2015.  Currently awaiting supplemental information requests and feedback from the Alberta Energy Regulator (AER).
  • An amended Human Health Risk Assessment was filed on the website following feedback from Alberta Health.
  • An update to the draft Remediation Plan has been submitted to the AER for review and input. Accompanying this report was an executive summary that describes the proposed activities of the Remediation Sub Plans.
  • An amendment to the Long-Term Sampling and Monitoring Plan was approved by the AER. The amendment reduces the frequency of sampling at some sites from twice weekly to monthly.
  • Water sampling and monitoring data continues to be posted on a weekly and monthly basis under Data Collection.

Human Health Risk Assessment, Impact Assessment Report and Remediation Activities Report and Plan now available on Obed website

  • An updated human health risk assessment was reviewed by Alberta Health, comments have been incorporated and it is now posted on the Obed website. Based on data interpretation to date, no adverse effects are predicted for the scenarios evaluated.
  • Visual inspections are being carried out on sediment traps, silt curtains and streams. A work plan is under developed to remove sediment from these locations, which will be sampled and recorded. The Alberta Energy Regulator (AER) monitors results.
  • A site inspection under the Environmental Protection Order (EPO) was carried out by the AER on April 21, 2015.
  • An additional sampling program was completed on ponds that discharge into Baseline Creek.
  • The latest Impact Assessment Report has been released and indicates no residual, measurable effects on water or sediment quality in Obed area creeks or the Athabasca River. The report also notes that re-vegetation and weed control measures will assist in vegetation recovery; that wildlife surveys have confirmed the presence of mammals, carnivores, hares and rodents; and that the release had measurable but minor effects on fish and fish habitat in upper Apetowun Creek (now stabilized or partially recovered).
  • A comprehensive update on remediation activities carried out between November 2013 and August 2014 is available in the Remediation Activities Report and Plan. This document also contains descriptions of ongoing fieldwork.
  • Sampling and monitoring programs are ongoing as per the Long-Term Sampling and Monitoring Plan spring / summer EPO requirements.
