Dockage for vessels or other floating equipment under repair at piers not currently required for other purposes, available only, shall be charged at the rate of three-fourths the full dockage per day, or any fraction of a day, providing such repair is considered major repair and is performed by a repair firm. To prevent misunderstanding, this rate shall be assessed only with prior approval of the department. Without such prior approval full dockage shall be charged.
