				  Department of Health and Hospitals. The empty depuration tanks shall then be
				  flushed with potable water to remove all filth and waste matter. The depuration
				  tanks shall be sanitized with an approved sanitizing agent prior to being
				  refilled with shellfish and treated sea water. When wet storage is practiced
				  the tanks shall be drained, flush, and sanitized a minimum of once every seven
				  days.
