§ 789.51 Audits and investigations. ( a ) Audits and investigations are official examinations of books, records, documents, other writings, and information to ensure that the provisions of the Defense Production Act and other applicable statutes, this part, and official actions have been properly followed. An audit or investigation may also include interviews and a systems evaluation to detect problems or failures in the implementation of this part.
( b ) When undertaking an audit, investigation, or other inquiry, USDA will: ( 1 ) *Scope and purpose.* Define the scope and purpose in the official action given to the person under investigation; and
( 2 ) *Information not available.* Have ascertained that the information sought or other adequate and authoritative data are not available from any Federal or other responsible agency.
( c ) In administering this part, USDA may issue the following documents that constitute official actions: ( 1 ) *Administrative subpoenas.* An administrative subpoena requires a person to appear as a witness before an official designated by USDA to testify under oath on matters of which that person has knowledge relating to the enforcement or the administration of the Defense Production Act and other applicable laws, this part, or official actions. An administrative subpoena may also require the production of books, papers, records, documents, and physical objects or property.
( 2 ) *Demands for information.* A demand for information requires a person to furnish to a duly authorized representative of USDA any information necessary or appropriate to the enforcement or the administration of the Defense Production Act and other applicable statutes, this part, or official actions.
( 3 ) *Inspection authorizations.* An inspection authorization requires a person to permit a duly authorized representative of USDA to interview the person's employees or agents, to inspect books, records, documents, other writings, and information, including electronically-stored information, in the person's possession or control at the place where that person usually keeps them or otherwise, and to inspect a person's property when such interviews and inspections are necessary or appropriate to the enforcement or the administration of the Defense Production Act and other related laws, this part, or official actions.
( d ) The production of books, records, documents, other writings, and information will not be required at any place other than where they are usually kept if, prior to the return date specified in the administrative subpoena or demand for information, a duly authorized official of USDA is furnished with copies of such material that are certified under oath to be true copies. As an alternative, a person may enter into a stipulation with a duly authorized official of USDA as to the content of the material.
( e ) An administrative subpoena, demand for information, or inspection authorization will include the name, title, or official position of the person to be served, the evidence sought, and its general relevance to the scope and purpose of the audit, investigation, or other inquiry. If employees or agents are to be interviewed; if books, records, documents, other writings, or information are to be produced; or if property is to be inspected; the administrative subpoena, demand for information, or inspection authorization will describe the requirements.
( f ) Service of documents will be made in the following manner: ( 1 ) *In person.* Service of a demand for information or inspection authorization will be made personally, or by certified mail-return receipt requested at the person's last known address. Service of an administrative subpoena will be made personally. Personal service may also be made by leaving a copy of the document with someone at least 18 years old at the person's last known dwelling or place of business.
( 2 ) *Other than to the named individual.* Service upon other than an individual may be made by serving a partner, corporate officer, or a managing or general agent authorized by appointment or by law to accept service of process. If an agent is served, a copy of the document will be mailed to the person named in the document.
( 3 ) *Delivering individual and documentation.* Any individual 18 years of age or over may serve an administrative subpoena, demand for information, or inspection authorization. When personal service is made, the individual making the service must prepare an affidavit specifying the manner in which service was made and the identity of the person served, and return the affidavit, and in the case of subpoenas, the original document, to the issuing officer. In case of failure to make service, the reasons for the failure will be stated on the original document.
