The request shall include a statement of the alleged inaccuracy or incompleteness in the record, its materiality, and shall specify any proof or corroboration available.

The agency shall furnish the applicant with a list of all the noncriminal justice agencies to which the incorrect record has been disseminated from an automated system in the past two years unless it interferes with the conduct of an authorized investigation.
