Persons actually or potentially affected by the Act or regulations in this Part may request an interpretation of the Act or regulations by writing to the Terrorism Risk Insurance Program Office, Room 1410, Department of the Treasury, 1500 Pennsylvania Ave. NW., Washington, DC 20220, giving a detailed explanation of the facts and circumstances and the reason why an interpretation is needed. A requester should segregate and mark any confidential business or trade secret information clearly. Treasury in its discretion will provide written responses to requests for interpretation. 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.
