Start with sample jars, culvert flow notes and mill operating cards. It is the source used to decide how a discharge sample can be compared when flow changes across a shift; it is not the decision itself. The rule only works if the source describes conditions at the west discharge culvert.

Known: the current file counts 50 samples with a time, flow and operating condition attached, compared with 45 in the prior window. The board publishes options with paid time, water use or cost shown separately. The entries have dates and a named clerk.

Disputed: The mill tests at the end of a run. Residents ask for a sample during the rinse as well as after it. One side emphasizes the posted total; the other points to the culvert flow rises after the late furnace rinse.

Why it matters: the decision determines which residents can rely on the service and which staff must carry out the change. The file does not settle that by itself.

Next: The Year fifth, cooling weeks window 2 file remains open for its scheduled decision. The sample desk will collect paired jars before and after the rinse.
