Description of the Applications
TransAlta has applied for the Highvale Mine No. 1769: 

  • To amend and renew EPEA Approval No. 00011187-03-00, as amended, to change from an operating approval to a reclamation and closure approval;
  • To renew WA Approval Nos. 00240557-01-00, as amended, and 00079264-01-00, and to approve amended plans for the decommissioning of regulated dams, restoration of watersheds, establishment of sustainable end pit lakes and closure wetlands, and recovery of groundwater levels;
  • Under the CCA and Coal Conservation Rules (CCR) to:
    • Renew the active pit Licences for Pit 05 (C 2016-6, C 2016-6A, and C 2016-6B) and Pit 06 (C 2016-7 and C 2016-7A) for ash excavation; 
    • Consent to abandon existing coal mine Licences C 2016-4 and C 2016-4A (for Pit 03), C 2016-5 (for Pit 04), C 2016-8 (for Pit 07 ), C 2016-9 and C 2016-9A (for Pit 08), and C 2015-4 (for Pit 09); 
    • Consent to abandon existing external dump Licenses C 2015-5(for the Pit 09 external dump), C 93-30(the east external discard dump), and C 93-29 (the west external discard dump); and
    • Amend the Mine Permit C 88-8 to remove the undisturbed 900 ha around Pit 09.

Active coal mining at Highvale Mine ceased at the end of December 2021 and the Highvale Mine plans to have active reclamation completed by 2046. The applications reflect the change in mine plans as the decision to close the Highvale Mine earlier than the originally planned closure date of 2061 has been made due to the transition from coal based electrical generation to natural gas based generation. 

The Highvale Mine is located in portions of Townships 050, 051 and 052, Ranges 03, 04 and 05, West of the 5th Meridian, near Wabamun, Alberta, as detailed in the application materials.
