Each utility shall:
(7) During July and August of each year, consumption for each customer for the twelve-months ending June 30 of such year and the prior year shall be reviewed. If it is found that the customer has either increased or decreased his annual consumption based on the two prior years' consumption to the point it would place him on a different rate schedule, the customer shall be automatically reclassified to the proper rate schedule effective the following September 1. In determining consumption, periods of involuntary curtailment shall be excluded.
Each customer reclassified under this rule shall be notified of the change in rate schedule, along with a copy of the tariff sheets applicable to his old and new rate schedules, at least twenty-one days prior to the effective date of the change.
