When the agency requests a person to supply information about that person, the agency shall notify the person of the use that will be made of the information, which persons outside the agency might routinely be provided this information, which parts of the requested information are required and which are optional, and the consequences of a failure to provide the information requested. This notice may be given in these rules, on the written form used to collect the information, on a separate fact sheet or letter, in brochures, in formal agreements, in contracts, in handbooks, in manuals, verbally, or by other appropriate means. Notice need not be given in connection with discovery requests in litigation or administrative proceedings, subpoenas, investigations of possible violations of law, or similar demands for information.
