What is considered bulk oil storage capacity?

The revised rule recognizes that oil is sometimes stored in bulk and sometimes used operationally.  A bulk storage container is any container storing oil at a facility.  Bulk oil storage containers may include, but are not limited to tanks, containers, drums, and mobile or portable totes.  Operational use includes oil-filled electrical equipment and manufacturing equipment.  Operational use of oil is not subject to the rule's bulk storage requirements.  (See §112.8 for bulk storage requirements).  The shell capacity of the container (maximum volume) must be considered and not the actual amount of product stored in the container (operational volume).
