Abstract
The Ontario Ministry of the Environment (MOE) has identified the need to develop and/or update air quality standards for priority contaminants. The Ministry’s Standards Plan, which was released in October, 1996 and revised in October, 1999, identified candidate substances for which current air standards will be reviewed. Once all consultations have been completed, all substances will be incorporated into the Regulation as standards (as opposed to guidelines). n-Butanol was identified as a high priority compound for review based on its pattern of use in Ontario and recent toxicological information that has been published subsequent to the development of the existing standard in 1986. A review of scientific and technical information relevant to setting an air quality standard for n-butanol has previously been provided to stakeholders for their comments. This document provides the rationale for recommending Ambient Air Quality Criteria (AAQC) and half-hour Point of Impingement (POI) standards for n-butanol. n-Butanol, commonly referred to as butyl alcohol, is a colourless, flammable liquid with a rancid, sweet odour. n-Butanol occurs naturally as a product of fermentation of

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.
