Treasury reserves the right to decline to provide a response in any case. Except in the case of any confidential business or trade secret information, Treasury will make written requests for interpretations and responses publicly available at the Treasury Department Library, on the Treasury Web site, or through other means as soon as practicable after the response has been provided. Treasury will handle any subsequent request for information that had been designated by a requester as confidential business or trade secret information in accordance with Treasury's Freedom of Information Act regulations at 31 CFR part 1.
