§ 2.337 Evidence at a hearing. Cross Reference
Link to an amendment published at 89 FR 67834 , Aug. 22, 2024.
( a ) *Admissibility.* Only relevant, material, and reliable evidence which is not unduly repetitious will be admitted. Immaterial or irrelevant parts of an admissible document will be segregated and excluded so far as is practicable.
( b ) *Objections.* An objection to evidence must briefly state the grounds of objection. The transcript must include the objection, the grounds, and the ruling. Exception to an adverse ruling is preserved without notation on-the-record.
( c ) *Offer of proof.* An offer of proof, made in connection with an objection to a ruling of the presiding officer excluding or rejecting proffered oral testimony, must consist of a statement of the substance of the proffered evidence. If the excluded evidence is in written form, a copy must be marked for identification. Rejected exhibits, adequately marked for identification, must be retained in the record.
( d ) *Exhibits.* Exhibits must be filed through the agency's E-Filing system, unless the presiding officer grants an exemption permitting an alternative filing method under § 2.302(g)(2) or (g)(3) or unless the filing falls within the scope of § 2.302(g)(1) as not being subject to electronic transmission. When an exhibit is not filed through the E-Filing system, the presiding officer may permit a party to replace with a true copy an original document admitted into evidence. Information that a party references through hyperlinks in an exhibit must be submitted by that party, in its entirety, either as part of the exhibit or as a separate exhibit, for that information to be included in the evidentiary record.
( e ) *Official record.* An official record of a government agency or entry in an official record may be evidenced by an official publication or by a copy attested by the officer having legal custody of the record and accompanied by a certificate of their custody.
( f ) *Official notice.* ( 1 ) The Commission or the presiding officer may take official notice of any fact of which a court of the United States may take judicial notice or of any technical or scientific fact within the knowledge of the Commission as an expert body. Each fact officially noticed under this paragraph must be specified in the record with sufficient particularity to advise the parties of the matters which have been noticed or brought to the attention of the parties before final decision and each party adversely affected by the decision shall be given opportunity to controvert the fact.
( 2 ) If a decision is stated to rest in whole or in part on official notice of a fact which the parties have not had a prior opportunity to controvert, a party may controvert the fact by filing an appeal from an initial decision or a petition for reconsideration of a final decision. The appeal must clearly and concisely set forth the information relied upon to controvert the fact.
( g ) *Proceedings involving applications* — ( 1 ) Facility construction permits . In a proceeding involving an application for construction permit for a production or utilization facility, the NRC staff shall offer into evidence any report submitted by the ACRS in the proceeding in compliance with section 182(b) of the Act, any safety evaluation prepared by the NRC staff, and any environmental impact statement prepared in the proceeding under subpart A of part 51 of this chapter by the Director, Office of Nuclear Reactor Regulation, or Director, Office of Nuclear Material Safety and Safeguards, as appropriate, or their designee.
( 2 ) Other applications where the NRC staff is a party. In a proceeding involving an application for other than a construction permit for a production or utilization facility, the NRC staff shall offer into evidence: ( i ) Any report submitted by the ACRS in the proceeding in compliance with section 182(b) of the Act;
( ii ) At the discretion of the NRC staff, a safety evaluation prepared by the NRC staff and/or NRC staff testimony and evidence on the contention or contested matter prepared in advance of the completion of the safety evaluation;
( iii ) Any NRC staff statement of position on the contention or contested matter provided to the presiding officer under § 2.1202(a); and
( iv ) Any environmental impact statement or environmental assessment prepared in the proceeding under subpart A of part 51 of this chapter by the Director, Office of Nuclear Reactor Regulation, or Director, Office of Nuclear Material Safety and Safeguards, as appropriate, or their designee if there is any, but only if there are admitted contentions or contested matters with respect to the adequacy of the environmental impact statement or environmental assessment.
( 3 ) Other applications where the NRC staff is not a party. In a proceeding involving an application for other than a construction permit for a production or utilization facility, the NRC staff shall offer into evidence, and (with the exception of an ACRS report) provide one or more sponsoring witnesses, for: ( i ) Any report submitted by the ACRS in the proceeding in compliance with section 182(b) of the Act;
( ii ) At the discretion of the NRC staff, a safety evaluation prepared by the NRC staff and/or NRC staff testimony and evidence on the contention or contested matter prepared in advance of the completion of the safety evaluation;
( iii ) Any NRC staff statement of position on the contention or contested matter under § 2.1202(a); and
( iv ) Any environmental impact statement or environmental assessment prepared in the proceeding under subpart A of part 51 of this chapter by the Director, Office of Nuclear Reactor Regulation, or Director, Office of Nuclear Material Safety and Safeguards, as appropriate, or their designee if there is any, but only if there are admitted contentions or contested matters with respect to the adequacy of the environmental impact statement or environmental assessment.
