(2) The agency order or the applicant's request stated grounds for confidential treatment which fall within one of the exemptions described in paragraphs (1) through (9) of 5 U.S.C. 552(b).

(b) Upon receipt of a request for disclosure of information treated as confidential under paragraph (a) of this section, the Commission will determine in accordance with 5 U.S.C. 552 whether the information is exempt. 5 U.S.C. 552(b). If it determines the information is not exempt, the information will be made public.
