REMEDIATION OF COAL WASTE PILE IN
Bibliographic record
Abstract
During the late 1800’s to early 1900’s, a coal processing plant operated in the community of Union Bay on Vancouver Island. Waste coal was deposited onto the foreshore and today this waste pile occupies approximately 13 hectares of leased Crown Land on the waterfront. The waste pile is also bounded on one side by a fish-bearing creek, with an environmentally sensitive buffer zone along its length. Under oxidizing, moist conditions, acid may be produced by sulphides in coal waste materials and can cause heavy elements and low pH conditions to be released into groundwater. Concerns have arisen over the acid generating potential of the Union Bay waste pile, its potential impacts on foreshore and aquatic ecology, and the selection of appropriate mitigating options that will address the concerns of multiple stakeholders. Over the years, the waste pile has become a popular community park and a renowned destination for biking enthusiasts. The future land use of the pile has thus become an important and sensitive community issue.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
