(a) The Defense Nuclear Facilities Safety Board (Board) is an independent federal agency in the executive branch of the United States Government.

(b) The Board's enabling legislation authorizes it to conduct safety investigations pursuant to the Atomic Energy Act of 1954, as amended (42 U.S.C. 2286a(b)(2)).

(a) The Board shall investigate any event or practice at a Department of Energy defense nuclear facility which the Board determines has adversely affected, or may adversely affect, public health and safety.

(b) The purpose of any Board investigation shall be:

(1) To determine whether the Secretary of Energy is adequately implementing standards (including all applicable Department of Energy orders, regulations, and requirements) at Department of Energy defense nuclear facilities;

(2) To ascertain information concerning the circumstances of such event or practice and its implications for such standards;

(3) To determine whether such event or practice is related to other events or practices at other Department of Energy defense nuclear facilities; and

(4) To provide to the Secretary of Energy such recommendations for changes in such standards or the implementation of such standards (including Department of Energy orders, regulations, and requirements) and such recommendations relating to data or research needs as may be prudent or necessary.

(a) The Board may initiate a preliminary safety inquiry or order a formal safety investigation.

(b) A preliminary safety inquiry means any inquiry conducted by the Board or its staff, other than a formal investigation. Where it appears from a preliminary safety inquiry that a formal safety investigation is appropriate, the Board's staff will so recommend to the Board.

(c) A formal safety investigation is instituted by an Order of Safety Investigation issued either after a recorded notational vote of Board Members or after convening a meeting in accordance with the Government in the Sunshine Act and voting in open or closed session, as the case may be.

(d) Orders of Safety Investigations will outline the basis for the investigation, the matters to be investigated, the Investigating Officer(s) designated to conduct the investigation, and their authority.

(e) The Office of the General Counsel shall have primary responsibility for conducting and leading a formal safety investigation. The Investigating Officer(s) shall report to the Board.

(f) Following a notational vote and in accordance with the Government in the Sunshine Act, the Board or an individual Board Member authorized by the Board may hold such closed or open hearings and sit and act at such times and places, and require the attendance and testimony of such witnesses and the production of such evidence as the Board or an authorized member may find advisable, or exercise any other applicable authority as provided in the Board's enabling legislation. Each Board Member shall have full access to all information relating to the matter under investigation, including attendance at closed hearings.

(g) Subpoenas in formal safety investigation hearings may be issued by the Chairman only after a notational vote of the Board. The Chairman may designate another Board Member to issue a subpoena. Subpoenas shall be served by any person designated by the Chairman, or otherwise as provided by law.

(h) A determination of a decision or action authorized to the Board by these procedures shall only be made after a notational vote of the Board with each Board Member having one vote.

(a) Any person may request that the Board perform a preliminary safety inquiry or conduct a formal safety investigation concerning a matter within the Board's jurisdiction.

(b) Actions the Board may take regarding safety investigation requests are discretionary.

(c) The Board will offer to protect the identity of a person requesting a safety investigation to the maximum extent permitted by law.

(d) Board safety investigations are wholly administrative and investigatory in nature and do not involve a determination of criminal culpability, adjudication of rights and duties, or other quasi-judicial determinations.

(a) Information obtained during the course of a preliminary safety inquiry or a formal safety investigation may be treated as confidential, safety privileged, and non-public by the Board and its staff, to the extent permissible under existing law. The information subject to this protection includes but is not limited to: Identity of witnesses; recordings; statements; testimony; transcripts; emails; all documents, whether or not obtained pursuant to Board subpoena; any conclusions based on privileged safety information; any deliberations or recommendations as to policies to be pursued; and all other related investigative proceedings and activities.

(b) The Board shall have the discretion to assert the safety privilege when safety information, determined by the Board as protected from release, is sought by any private or public governmental entity or by parties to litigation who attempt to compel its release.

(c) Nothing in this section voids or otherwise displaces the Board's legal obligations with respect to the Freedom of Information Act, the Government in the Sunshine Act, or any procedures or requirements contained in the Board's regulations issued pursuant to those Acts.

(a) The Investigating Officer(s) may give a promise of confidentiality to any individual who provides evidence for a safety inquiry or investigation to encourage frank communication.

(b) A promise of confidentiality must be explicit.

(c) A promise of confidentiality must be documented in writing.

(d) A promise of confidentiality may be given only as needed to ensure forthright cooperation of a witness and may not be given on a blanket basis to all witnesses.

(e) A promise of confidentiality must inform the witness that it applies only to information given to the Investigating Officer(s) and not to the same information if given to others.

(a) A safety investigation under this rule is not a judicial or adjudicatory proceeding.

(b) No person or entity has standing to intervene or participate as a matter of right in any safety investigation under this regulation.

The Investigating Officer(s) appointed by the Board may take informal or formal statements, interview witnesses, take testimony, request production of documents, recommend issuance of subpoenas, recommend taking of testimony in a closed forum, recommend administration of oaths, and otherwise perform any lawful act authorized under the Board's enabling legislation in connection with any safety investigation ordered by the Board.

(a) Section 2286c(a) of the Atomic Energy Act of 1954, as amended, requires the Department of Energy to fully cooperate with the Board and provide the Board with ready access to such facilities, personnel, and information as the Board considers necessary, including ready access in connection with a safety investigation.

(b) Each contractor operating a Department of Energy defense nuclear facility under a contract awarded by the Secretary is also required, to the extent provided in such contract or otherwise with the contractor's consent, to fully cooperate with the Board and provide the Board with ready access to such facilities, personnel, and information of the contractor as the Board considers necessary in connection with a safety investigation.

(c) The Board may make a written request to persons or entities relevant to the safety investigation to preserve pertinent information, documents, and evidence, including electronically stored information, in order to preclude alteration or destruction of that information.

(a) Any person who is compelled to appear in person to provide testimony or produce documents in connection with a safety investigation is entitled to be accompanied, represented, and advised by an attorney. Subpoenas in safety investigations shall issue only under signature of the Chairman or any Member of the Board designated by the Chairman. Attendance and testimony shall be before the Board or a Member authorized by the Board.

(b) If an executive branch agency employee witness is represented by counsel from that same agency, counsel shall identify who counsel represents to determine whether counsel represents multiple interests in the safety investigation.

(c) Counsel for a witness may advise the witness with respect to any question asked where it is claimed that the testimony sought from the witness is outside the scope of the safety investigation, or that the witness is privileged to refuse to answer a question or to produce other evidence. For these permissible objections, the witness or counsel may object on the record to the question and may state briefly and precisely the grounds therefore. If the witness refuses to answer a question, then counsel may briefly state on the record that counsel has advised the witness not to answer the question and the legal grounds for such refusal. The witness and his or her counsel shall not otherwise object to or refuse to answer any question, and they shall not otherwise interrupt any oral examination.

(d) When it is claimed that the witness has a privilege to refuse to answer a question on the grounds of self-incrimination, the witness must assert the privilege personally.

(e) Any objections made during the course of examination will be treated as continuing objections and preserved throughout the further course of testimony without the necessity for repeating them as to any similar line of inquiry.

(f) Counsel for a witness may not interrupt the examination by making any unnecessary objections or statements on the record.

(g) Following completion of the examination of a witness, such witness may make a statement on the record, and that person's counsel may, on the record, question the witness to enable the witness to clarify any of the witness's answers or to offer other evidence.

(h) The Board or any Member authorized by the Board shall take all measures necessary to regulate the course of an investigative proceeding to avoid delay and prevent or restrain obstructionist or contumacious conduct or contemptuous language.

(i) If the Board or any Member authorized by the Board finds that counsel for a witness, or other representative, has refused to comply with his or her directions, or has engaged in obstructionism or contumacy, the Board or Member authorized by the Board may thereupon take action as the circumstances may warrant.

(j) Witnesses appearing voluntarily do not have a right to have counsel present during questioning, although the Board or Member authorized by the Board, in consultation with the Office of the General Counsel, may permit a witness appearing on a voluntary basis to be accompanied by an attorney or non-attorney representative.

(a) If counsel representing a witness appears in connection with a safety investigation, counsel shall state on the record all other persons or entities counsel represents in that investigation.

(b) When counsel does represent more than one person or entity in a safety investigation, counsel shall inform the Investigating Officer(s) and each client of counsel's possible conflict of interest in representing that client.

(c) When an Investigating Officer(s), or the Board, as the case may be, in consultation with the Board's General Counsel, has concrete evidence that the presence of an attorney representing multiple interests would obstruct or impede the safety investigation, the Investigating Officer(s) or the Board may prohibit that attorney from being present during testimony.

(d) The Board shall issue a written statement of the reasons supporting a decision to exclude counsel under this section within five working days following exclusion. The Board shall also delay the safety investigation for a reasonable period of time to permit retention of new counsel.

(a) Witnesses shall be sequestered during interviews, or during the taking of testimony, unless otherwise permitted by the Investigating Officer(s) or by the Board, as the case may be.

(b) No witness, or counsel accompanying any such witness, shall be permitted to be present during the examination of any other witness called in such proceeding, unless permitted by the Investigating Officer(s) or the Board, as the case may be.

(a) Counsel appearing before the Board or the Investigating Officer(s) must conform to the standards of ethical conduct required of practitioners before the Courts of the United States.

(b) The Board may suspend or deny, temporarily or permanently, the privilege of appearing or practicing before the Board in any way to a person who is found:

(1) Not to possess the requisite qualifications to represent others; or

(2) To have engaged in unethical or improper professional conduct; or

(3) To have engaged in obstructionism or contumacy before the Board; or

(4) To be otherwise not qualified.

(c) Obstructionist or contumacious conduct in an investigation before the Board or the Investigating Officer(s) will be grounds for exclusion of any person from such safety investigation proceedings and for summary suspension for the duration of the investigation.

(d) At the time of the finding the Board shall issue a verbal or written statement of the reasons supporting a decision to suspend or exclude counsel for obstructionism or contumacy.

(e) A witness may have a reasonable amount of time to retain replacement counsel if original counsel is suspended or excluded.

At any time during the course of an investigation, any person may submit documents, statements of facts, or memoranda of law for the purpose of explanation or further development of the facts and circumstances relevant to the safety matter under investigation.

(a) Official transcripts of witness testimony, whether or not compelled by subpoena to appear before a Board safety investigation, shall be recorded either by an official reporter or by any other person or means designated by the Investigating Officer(s) or the Board's General Counsel.

(b) Such witness, after completing the compelled testimony, may file a request with the Board's General Counsel to procure a copy of the official transcript of that witness's testimony. The General Counsel shall rule on the request, and may deny for good cause.

(c) Good cause for denying a witness's request to procure a transcript may include, but shall not be limited to, the protection of a trade secret, non-disclosure of confidential or proprietary business information, security-sensitive operational or vulnerability information, safety privileged information, or the integrity of Board investigations.

(d) Whether or not a request is made, the witness and his or her attorney shall have the right to inspect the official transcript of the witness's own testimony, in the presence of the Investigating Officer(s) or his designee, for purposes of conducting errata review.

(e) Transcripts of testimony are otherwise considered confidential and privileged safety information, and in no case shall a copy or any reproduction of such transcript be released to any other person or entity, except as provided in paragraph (b) above or as required under the Freedom of Information Act or the Government in the Sunshine Act, or any procedures or requirements contained in Board regulations issued pursuant to those Acts.

(a) The Board will complete a final report of the safety investigation fully setting forth the Board's findings and conclusions.

(b) The final report of the safety investigation is confidential and protected by the safety privilege, and is therefore not releasable.

(c) The Board, in its discretion, may sanitize the final report of the safety investigation by redacting confidential and safety privileged information so that the report is put in a publically releasable format.

(d) Nothing in this section voids or otherwise displaces the Board's legal obligations with respect to compliance with the Freedom of Information Act, the Government in the Sunshine Act, or any procedures or requirements contained in the Board's regulations issued pursuant to those Acts.

(a) If a formal safety investigation results in a finding that an event or practice has adversely affected, or may adversely affect, public health and safety, the Board may take any appropriate action authorized to it under its enabling statute, including, but not limited to, making a formal recommendation to the Secretary of Energy, convening a hearing, or establishing a reporting requirement.

(b) If a safety investigation yields information relating to violations of federal criminal law involving government officers and employees, the Board shall expeditiously refer the matter to the Department of Justice for disposition.

(c) If in the course of a safety investigation, a safety issue or concern is found to be outside the Board's jurisdiction, that safety issue or concern shall be referred to the appropriate entity with jurisdiction for disposition.

(d) Statements made in connection with testimony provided to the Board in an investigation are subject to the provisions of 18 U.S.C. 1001.
