Spill Impact Assessment: Crude Oil Pipeline ERCB License Number 3353-1
Bibliographic record
Abstract
Gibson Energy performed a liquid pipeline spill analysis on the approximately 1 kilometre long 168.3 mm Crude Oil pipeline near the Edmonton South Terminal. This pipeline crosses a sensitive tributary that drains into the North Saskatchewan River. The pipeline is currently not in operation, however is locked in with product. This spill analysis is unique in that the pipeline is under minimal pressure with no appreciable flow rate. As a result, the objective of this analysis was to illustrate the length of time required to perform drain down at various locations along the pipeline. The Spill Analysis consisted of modeling a potential liquid release scenario for overland flow modeling of a liquid release and reports both direct and indirect High Consequence Area (HCA) impacts. Additionally, data showing spill plume extents, final volumes and other GIS data was generated for map generation. This presentation will discuss the methods, data, parameters, and results of this analysis and the next steps in providing regulators sufficient information for a comprehensive contingency plan of the Edmonton terminal.

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.
