(i) Specifically required by statute or Executive Order to be kept secret;

(ii) Commercial or financial information obtained from a person or firm on a privileged or confidential basis; or

(iii) Personnel, medical, social, psychological, academic achievement and similar files where disclosure would be a clearly unwarranted invasion of personal privacy; and

(2) Disclosure is prohibited by statute or Executive Order or sound grounds exist for using the exemption given in paragraph (b)(1) of this section.

(c) A request to inspect or copy reports and information must be in writing and reasonably describe the reports and information requested. The request may be delivered or mailed to the contractor. Within 10 working days after receiving the request, the contractor must determine whether to grant or deny the request and immediately notify the request of the determination.
