        (5) In the case of tier II information which is not
    
in the possession of the SERC or local emergency planning committee and which relates to a hazardous chemical which a facility has stored in an amount less than 10,000 pounds present at the facility at any time during the preceding calendar year, a request from a person must include the general need for the information.
