Steam Injection Well Control Incident Update #4

Jun 6, 2024 | Announcement

Stakeholder Update from Harvest Operations Corp.
June 06, 2024

Dear Community Members,

Harvest has established the impact area footprint, cleaning up the most heavily impacted areas continues. Harvest is working on the remediation plan for the remaining areas. In following the previous Stakeholder updates, we will highlight the changes that have occurred in the following four categories.

Site Clean-up Activities
  • Clearing and mulching of the heavily impacted vegetation is complete. The woody debris and shrubs were mulched and used to stabilize the waste disposal.
  • Hauling and disposal of waste stored on lease is complete until well maintenance operations finishes, and the remaining lease cleaning is done.
  • Cleaning of the third-party equipment and on-site infrastructure continues in prioritized order.
  • free-standing water & fluids have been removed and are being monitored an maintained as required.
Wildlife Management
  • Wildlife hazing continues on a 12-hour day shift basis. Hazing is provided on-site by site operations, and off-site in the release area with hazing crews equipped with Argos. This has so far been successful in the deterring the Caribou
  • Wildlife deterrents are being maintained and moved around every 2-3 days to disrupt any patterns wildlife has established around the perimeter of the moderately impacted vegetation.
  • Retention ponds are been drained and are being monitored to ensure a less desirable environment for birds maintained.
Vegetation Impact
  • Harvest, in consultation with the AER, have assessed and classified the area into four grades of impact; very lightly misted, lightly misted, moderately misted, and severely misted areas.
    – Very lightly misted area is affecting approximately 7,371,768 m2
    – Lights misted area is affecting approximately 1,230,723 m2
    – Moderately misted area is affecting approximately 496,447 m2
    – Severely misted area is affecting approximately 137,467 m2
    – Approximate release area boundary is 9,239,449 m2
  • Harvest met with the AER on-site on May 27th to inspect, discuss and clarify the impacted areas and remediation plan objectives. A Remedial Action Plan outlining how the remaining cleaning will be conducted is in development
  • We are working to preserve as much vegetation as possible, and this detail will be part of the remedial plan that we was developing. This means vegetation removal along cutlines and open areas should be conducted using hand tools to mitigate further disturbance. Maintenance of the of the moss layer is imperative.
Watercourse Impact
  • The unnamed water course is intermittent an unconfirmed within the wetland complex. due to recent heavy rainfall conditions, the nearby wetland complex currently has water present throughout the ephemeral watercourse.
  • Sampling and analysis from the watercourse confirmed no impacts were present in the water.

Going forward Harvest will not be publishing a regularly scheduled update as the work has become normalized, and progress will be focused for the next few weeks on disposal, mulching, assessing impacts, and developing a remedial plan. Future updates will be provided when there is a milestone update to communicate.
