Development of a technical guidance document for cover system design in cold regions
Bibliographic record
Abstract
The Contaminated Sites Programme of Indian and Northern Affairs Canada (INAC-CSP) is responsible for closure of contaminated sites on Crown land throughout the Canadian North. A significant percentage of the closure liabilities faced by Indian and Northern Affairs Canada (INAC) is associated with abandoned mines. Of these mine-related liabilities, at least one third involve the need to construct earthen cover systems over potentially reactive tailings and waste rock. INAC will be implementing cover systems at some sites in the very near future and therefore requires information on key physical, chemical, and biological processes that may affect long-term risk to these cover systems. This paper describes the technical guidance approach for cover systems in cold regions that is being developed by INAC with the assistance of a Technical Advisory Group (TAG). The focus of the paper is on the cover system design philosophy including the need to develop site specific closure objectives and criteria, mine closure planning and progressive reclamation, utilising attributes of cold regions, designing for sustainability, importance of final landform design, and assessment period and design life.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
