The AER is reviewing the applications together with the supporting documents.

This notice also sets out the deadline for filing a statement of concern under the section How to File a Statement of Concern.

Description of the Applications
CST Coal has applied under the CCA, EPEA and WA: 

  • to expand the No. 8 Surface Coal Mine to include a new mining pit (Saddle Pit) and access road;
  • to expand the existing Saddle Dump (SDP2) external mine discard dump; and 
  • to update water management plans and drainage control features associated with the new mine development areas that will integrate into the existing water management and drainage system.

The expansion is expected to yield approximately 2.3 million tonnes of metallurgical coal over a 5-year period, and result in an additional surface disturbance area of approximately 40 hectares (ha). The mine employs conventional open pit mining techniques using truck and shovel methods and is located about 20 kilometres (km) north of the hamlet of Grande Cache, Alberta.
