  Regulation: Ontario Milk Act — propane run-out as regulatory exposure on dairy
  show body at this version

  Confidence: Verified.

  Cross-citation between Ontario raw-milk regulation and propane-supply continuity on dairy operations. Frames why a propane run-out at a dairy parlour is a regulatory matter, not just a customer-service issue.

  Authority

  • Ontario Milk Act, R.S.O. 1990, c. M.12
  • Milk Industry — Plants Regulation, R.R.O. 1990, Reg. 761

  The Milk Act and Reg. 761 require defined sanitary standards for raw milk produced for shipment. Pickup is refused if CIP (clean-in-place) cleaning has not occurred to spec.

  OMAFRA bulk-tank requirement

  Milk must reach 1–4°C within two hours of first milking (OMAFRA bulk-tank cooling guidance).

  Why this is a propane regulation, not a fuel regulation

  A propane run-out that disables the parlour CIP wash creates direct regulatory exposure under the Milk Act:

  1. CIP wash cycle requires start 71–77°C, return ≥49°C (see op-dairy-parlour-propane-load-profile).
  2. Without hot wash, the milk pickup truck refuses load — DFO Grade A standard infraction.
  3. The infraction is regulatory, not contractual. The Milk Act sets the standard; pickup refusal is the enforcement mechanism.
  4. Bulk-tank cooling itself is electric, but the wash that has to happen before the next milking is propane-dependent. If the wash doesn't run hot enough, the milk truck doesn't load.

  Operational implication

  The economic asymmetry: a single missed milk pickup can cost many times the price of an emergency propane fill. Keep-full + telemetry on a dairy account is regulatory risk management, not premium service. See op-livestock-telemetry-keep-full-considerations.
