502.13—Exemptions.
In the event any document or record requested hereunder should contain material which is exempt from disclosure under this section, any reasonably segregable portion of the record will, notwithstanding that fact, and to the extent feasible, be provided to any person requesting it, after deletion of the portions which are exempt under this section.
