All containers shall be constructed of non‑absorbent and rust‑proof material, and kept clean and free from foreign matter. Burlap bags or similar absorbent material shall not be used for transporting shellstock to the depuration facility nor for the removal of shellstock from the facility.

Baskets shall be of a design to allow water to flow freely over the shellstock in the depuration tanks. Shellstock shall not be placed more than three inches deep in the baskets. Baskets shall be stacked in a manner to allow free circulation of water. There shall be at least three inches clearance separating containers of shellfish in tanks and between the containers and the bottom and sides of the tank. Containers used for depuration purposes shall not be used for any other purpose and no containers or other equipment shall be placed in the depuration tanks.

After each 24 hours the sea water in the tanks shall be drained out and the shellstock hosed down thoroughly with water from a supply approved by the Division under Rule .0413 of this Subchapter. All waste matter must be flushed out of the tank. Immediately after hosing, the tanks shall again be filled with treated sea water.
