Highvale Mine Decommissioning & Reclamation Plan and 10-year Renewal

Active coal mining at TransAlta’s Highvale Mine ceased at the end of December 2021 with the end of coal-fired generation at the Keephills and Sundance power plants. Operations at the Highvale Mine shifted to full-time reclamation in January 2022 with plans to have the Highvale Mine fully reclaimed by 2046.

TransAlta Corporation (“TransAlta”) will be submitting under the Environmental Protection and Enhancement Act (“EPEA”) a combined Decommissioning Plan and Final Reclamation Plan for the Highvale Mine to the Alberta Energy Regulator (“AER”) in June 2022. At the same time, TransAlta will file a 10-year Renewal for the Highvale Mine under EPEA, the Water Act and the Coal Conservation Act.
