(a) DOE shall determine, under the procedures in the CEQ Regulations and this part, whether any DOE proposal:

(1) Requires preparation of an EIS;

(2) Requires preparation of an EA; or

(3) Is categorically excluded from preparation of either an EIS or an EA.

(b) Notwithstanding any other provision of these regulations, DOE may prepare a NEPA document for any DOE action at any time in order to further the purposes of NEPA. This may be done to analyze the consequences of ongoing activities, support DOE planning, assess the need for mitigation, fully disclose the potential environmental consequences of DOE actions, or for any other reason. Documents prepared under this paragraph shall be prepared in the same manner as DOE documents prepared under paragraph (a) of this section.

(a) DOE shall make its NEPA documents available to other Federal agencies, states, local governments, American Indian tribes, interested groups, and the general public, in accordance with 40 CFR 1506.6, except as provided in § 1021.340 of this part.

(b) Wherever feasible, DOE NEPA documents shall explain technical, scientific, or military terms or measurements using terms familiar to the general public, in accordance with 40 CFR 1502.8.

(c) DOE shall notify the host state and host tribe of a DOE determination to prepare an EA or EIS for a DOE proposal, and may notify any other state or American Indian tribe that, in DOE's judgment, may be affected by the proposal.

(d) DOE shall provide the host state and host tribe with an opportunity to review and comment on any DOE EA prior to DOE's approval of the EA. DOE may also provide any other state or American Indian tribe with the same opportunity if, in DOE's judgment, the state or tribe may be affected by the proposed action. At DOE's discretion, this review period shall be from 14 to 30 days. DOE shall consider all comments received from a state or tribe during the review period before approving or modifying the EA, as appropriate. If all states and tribes afforded this opportunity for preapproval review waive such opportunity, or provide a response before the end of the comment period, DOE may proceed to approve or take other appropriate action on the EA before the end of the review period.

(e) Paragraphs (c) and (d) of this section shall not apply to power marketing actions, such as rate-setting, in which a state or American Indian tribe is a customer, or to any other circumstances where DOE determines that such advance information could create a conflict of interest.

DOE shall prepare and circulate EISs and related RODs in accordance with the requirements of the CEQ Regulations, as supplemented by this subpart. DOE shall include in draft and final EISs a disclosure statement executed by any contractor (or subcontractor) under contract with DOE to prepare the EIS document, in accordance with 40 CFR 1506.5(c).

(a) DOE shall publish an NOI in the Federal Register in accordance with 40 CFR 1501.7 and containing the elements specified in 40 CFR 1508.22 as soon as practicable after a decision is made to prepare an EIS. However, if there will be a lengthy period of time between its decision to prepare an EIS and the time of actual preparation, DOE may defer publication of the NOI until a reasonable time before preparing the EIS, provided that DOE allows a reasonable opportunity for interested parties to participate in the EIS process. Through the NOI, DOE shall invite comments and suggestions on the scope of the EIS. DOE shall disseminate the NOI in accordance with 40 CFR 1506.6.

(b) If there will be a lengthy delay between the time DOE has decided to prepare an EIS and the beginning of the public scoping process, DOE may publish an Advance NOI in the Federal Register to provide an early opportunity to inform interested parties of the pending EIS or to solicit early public comments. This Advance NOI does not serve as a substitute for the NOI provided for in paragraph (a) of this section.

(c) Publication of the NOI in the Federal Register shall begin the public scoping process. The public scoping process for a DOE EIS shall allow a minimum of 30 days for the receipt of public comments.

(d) DOE shall hold at least one public scoping meeting as part of the public scoping process for a DOE EIS. DOE shall announce the location, date, and time of public scoping meetings in the NOI or by other appropriate means, such as additional notices in the Federal Register, news releases to the local media, or letters to affected parties. Public scoping meetings shall not be held until at least 15 days after public notification. Should DOE change the location, date, or time of a public scoping meeting, or schedule additional public scoping meetings, DOE shall publicize these changes in the Federal Register or in other ways as appropriate.

(e) In determining the scope of the EIS, DOE shall consider all comments received during the announced comment period held as part of the public scoping process. DOE may also consider comments received after the close of the announced comment period.

(f) A public scoping process is optional for DOE supplemental EISs (40 CFR 1502.9(c)(4)). If DOE initiates a public scoping process for a supplemental EIS, the provisions of paragraphs (a) through (e) of this section shall apply.

(a) The public review and comment period on a DOE draft EIS shall be no less than 45 days (40 CFR 1506.10(c)). The public comment period begins when EPA publishes a Notice of Availability of the document in the Federal Register.

(b) DOE shall hold at least one public hearing on DOE draft EISs. Such public hearings shall be announced at least 15 days in advance. The announcement shall identify the subject of the draft EIS and include the location, date, and time of the public hearings.

(c) DOE shall prepare a final EIS following the public comment period and hearings on the draft EIS. The final EIS shall respond to oral and written comments received during public review of the draft EIS, as provided at 40 CFR 1503.4. In addition to the requirements at 40 CFR 1502.9(b), a DOE final EIS may include any Statement of Findings required by 10 CFR part 1022, “Compliance with Floodplain and Wetland Environmental Review Requirements,” or a Statement of Findings may be issued separately.

(d) DOE shall use appropriate means to publicize the availability of draft and final EISs and the time and place for public hearings on a draft EIS. The methods chosen should focus on reaching persons who may be interested in or affected by the proposal and may include the methods listed in 40 CFR 1506.6(b)(3).

(a) DOE shall prepare a supplemental EIS if there are substantial changes to the proposal or significant new circumstances or information relevant to environmental concerns, as discussed in 40 CFR 1502.9(c)(1).

(b) DOE may supplement a draft EIS or final EIS at any time, to further the purposes of NEPA, in accordance with 40 CFR 1502.9(c)(2).

(c) When it is unclear whether or not an EIS supplement is required, DOE shall prepare a Supplement Analysis.

(1) The Supplement Analysis shall discuss the circumstances that are pertinent to deciding whether to prepare a supplemental EIS, pursuant to 40 CFR 1502.9(c).

(2) The Supplement Analysis shall contain sufficient information for DOE to determine whether:

(i) An existing EIS should be supplemented;

(ii) A new EIS should be prepared; or

(iii) No further NEPA documentation is required.

(3) DOE shall make the determination and the related Supplement Analysis available to the public for information. Copies of the determination and Supplement Analysis shall be provided upon written request. DOE shall make copies available for inspection in the appropriate DOE public reading room(s) or other appropriate location(s) for a reasonable time.

(d) DOE shall prepare, circulate, and file a supplement to a draft or final EIS in the same manner as any other draft and final EISs, except that scoping is optional for a supplement. If DOE decides to take action on a proposal covered by a supplemental EIS, DOE shall prepare a ROD in accordance with the provisions of § 1021.315 of this part.

(e) When applicable, DOE will incorporate an EIS supplement, or the determination and supporting Supplement Analysis made under paragraph (c) of this section, into any related formal administrative record on the action that is the subject of the EIS supplement or determination (40 CFR 1502.9(c)(3)).

(a) No decision may be made on a proposal covered by an EIS during a 30-day “waiting period” following completion of the final EIS, except as provided at 40 CFR 1506.1 and 1506.10(b) and § 1021.211 of this part. The 30-day period starts when the EPA Notice of Availability for the final EIS is published in the Federal Register.

(b) If DOE decides to take action on a proposal covered by an EIS, a ROD shall be prepared as provided at 40 CFR 1505.2 (except as provided at 40 CFR 1506.1 and § 1021.211 of this part).

(c) DOE RODs shall be published in the Federal Register and made available to the public as specified in 40 CFR 1506.6, except as provided in 40 CFR 1507.3(c) and § 1021.340 of this part.

(d) No action shall be taken until the decision has been made public. DOE may implement the decision before the ROD is published in the Federal Register if the ROD has been signed and the decision and the availability of the ROD have been made public by other means (e.g., press release, announcement in local media).

(e) DOE may revise a ROD at any time, so long as the revised decision is adequately supported by an existing EIS. A revised ROD is subject to the provisions of paragraphs (b), (c), and (d) of this section.

DOE shall prepare and circulate EAs and related FONSIs in accordance with the requirements of the CEQ Regulations, as supplemented by this subpart.

(a) When to prepare an EA. As required by 40 CFR 1501.4(b), DOE shall prepare an EA for a proposed DOE action that is described in the classes of actions listed in appendix C to subpart D of this part, and for a proposed DOE action that is not described in any of the classes of actions listed in appendices A, B, or D to subpart D, except that an EA is not required if DOE has decided to prepare an EIS. DOE may prepare an EA on any action at any time in order to assist agency planning and decisionmaking.

(b) Purposes. A DOE EA shall serve the purposes identified in 40 CFR 1508.9(a), which include providing sufficient evidence and analysis for determining whether to prepare an EIS or to issue a FONSI. If appropriate, a DOE EA shall also include any floodplain/wetlands assessment prepared under 10 CFR part 1022 and may include analyses needed for other environmental determinations.

(c) Content. A DOE EA shall comply with the requirements found at 40 CFR 1508.9. In addition to any other alternatives, DOE shall assess the no action alternative in an EA, even when the proposed action is specifically required by legislation or a court order.

(a) DOE shall prepare a FONSI only if the related EA supports the finding that the proposed action will not have a significant effect on the human environment. If a required DOE EA does not support a FONSI, DOE shall prepare an EIS and issue a ROD before taking action on the proposal addressed by the EA, except as permitted under 40 CFR 1506.1 and § 1021.211 of this part.

(b) In addition to the requirements found at 40 CFR 1508.13, a DOE FONSI shall include the following:

(1) Any commitments to mitigations that are essential to render the impacts of the proposed action not significant, beyond those mitigations that are integral elements of the proposed action, and a reference to the Mitigation Action Plan prepared under § 1021.331 of this part;

(2) Any “Statement of Findings” required by 10 CFR part 1022, “Compliance with Floodplain/Wetlands Environmental Review Requirements”;

(3) The date of issuance; and

(4) The signature of the DOE approving official.

(c) DOE shall make FONSIs available to the public as provided at 40 CFR 1501.4(e)(1) and 1506.6; DOE shall make copies available for inspection in the appropriate DOE public reading room(s) or other appropriate location(s) for a reasonable time.

(d) DOE shall issue a proposed FONSI for public review and comment before making a final determination on the FONSI if required by 40 CFR 1501.4(e)(2); DOE may issue a proposed FONSI for public review and comment in other situations as well.

(e) Upon issuance of the FONSI, DOE may proceed with the proposed action subject to any mitigation commitments expressed in the FONSI that are essential to render the impacts of the proposed action not significant.

(f) DOE may revise a FONSI at any time, so long as the revision is supported by an existing EA. A revised FONSI is subject to all provisions of this section.

(a) When required to support a DOE programmatic decision (40 CFR 1508.18(b)(3)), DOE shall prepare a programmatic EIS or EA (40 CFR 1502.4). DOE may also prepare a programmatic EIS or EA at any time to further the purposes of NEPA.

(b) A DOE programmatic NEPA document shall be prepared, issued, and circulated in accordance with the requirements for any other NEPA document, as established by the CEQ Regulations and this part.

(c) As a matter of policy when not otherwise required, DOE shall prepare site-wide EISs for certain large, multiple-facility DOE sites; DOE may prepare EISs or EAs for other sites to assess the impacts of all or selected functions at those sites.

(d) DOE shall evaluate site wide NEPA documents prepared under § 1021.330(c) at least every five years. DOE shall evaluate site-wide EISs by means of a Supplement Analysis, as provided in § 1021.314. Based on the Supplement Analysis, DOE shall determine whether the existing EIS remains adequate or whether to prepare a new site-wide EIS or supplement the existing EIS, as appropriate. The determination and supporting analysis shall be made available in the appropriate DOE public reading room(s) or in other appropriate location(s) for a reasonable time.

(e) DOE shall evaluate site-wide EAs by means of an analysis similar to the Supplement Analysis to determine whether the existing site-wide EA remains adequate, whether to prepare a new site-wide EA, revise the FONSI, or prepare a site wide EIS, as appropriate. The determination and supporting analysis shall be made available in the appropriate DOE public reading room(s) or in other appropriate location(s) for a reasonable time.

(a) Following completion of each EIS and its associated ROD, DOE shall prepare a Mitigation Action Plan that addresses mitigation commitments expressed in the ROD. The Mitigation Action Plan shall explain how the corresponding mitigation measures, designed to mitigate adverse environmental impacts associated with the course of action directed by the ROD, will be planned and implemented. The Mitigation Action Plan shall be prepared before DOE takes any action directed by the ROD that is the subject of a mitigation commitment.

(b) In certain circumstances, as specified in § 1021.322(b)(1), DOE shall also prepare a Mitigation Action Plan for commitments to mitigations that are essential to render the impacts of the proposed action not significant. The Mitigation Action Plan shall address all commitments to such necessary mitigations and explain how mitigation will be planned and implemented. The Mitigation Action Plan shall be prepared before the FONSI is issued and shall be referenced therein.

(c) Each Mitigation Action Plan shall be as complete as possible, commensurate with the information available regarding the course of action either directed by the ROD or the action to be covered by the FONSI, as appropriate. DOE may revise the Plan as more specific and detailed information becomes available.

(d) DOE shall make copies of the Mitigation Action Plans available for inspection in the appropriate DOE public reading room(s) or other appropriate location(s) for a reasonable time. Copies of the Mitigation Action Plans shall also be available upon written request.

(a) Notwithstanding other sections of this part, DOE shall not disclose classified, confidential, or other information that DOE otherwise would not disclose pursuant to the Freedom of Information Act (FOIA) (5 U.S.C. 552) and 10 CFR 1004.10(b) of DOE's regulations implementing the FOIA, except as provided by 40 CFR 1506.6(f).

(b) To the fullest extent possible, DOE shall segregate any information that is exempt from disclosure requirements into an appendix to allow public review of the remainder of a NEPA document.

(c) If exempt information cannot be segregated, or if segregation would leave essentially meaningless material, DOE shall withhold the entire NEPA document from the public; however, DOE shall prepare the NEPA document, in accordance with the CEQ Regulations and this part, and use it in DOE decisionmaking.

(a) In accordance with 40 CFR 1500.4(k) and (o), 1502.25, and 1506.4, DOE shall integrate the NEPA process and coordinate NEPA compliance with other environmental review requirements to the fullest extent possible.

(b) To the extent possible, DOE shall determine the applicability of other environmental requirements early in the planning process, in consultation with other agencies when necessary or appropriate, to ensure compliance and to avoid delays, and shall incorporate any relevant requirements as early in the NEPA review process as possible.

For DOE programs that involve another Federal agency or agencies in related decisions subject to NEPA, DOE will comply with the requirements of 40 CFR 1501.5 and 1501.6. As part of this process, DOE shall cooperate with the other agencies in developing environmental information and in determining whether a proposal requires preparation of an EIS or EA, or can be categorically excluded from preparation of either. Further, where appropriate and acceptable to the other agencies, DOE shall develop or cooperate in the development of interagency agreements to facilitate coordination and to reduce delay and duplication.

(a) Emergency actions. DOE may take an action without observing all provisions of this part or the CEQ Regulations, in accordance with 40 CFR 1506.11, in emergency situations that demand immediate action. DOE shall consult with CEQ as soon as possible regarding alternative arrangements for emergency actions having significant environmental impacts. DOE shall document, including publishing a notice in the Federal Register, emergency actions covered by this paragraph within 30 days after such action occurs; this documentation shall identify any adverse impacts from the actions taken, further mitigation necessary, and any NEPA documents that may be required.

(b) Reduction of time periods. On a case-by-case basis, DOE may reduce time periods established in this part that are not required by the CEQ Regulations. If DOE determines that such reduction is necessary, DOE shall publish a notice in the Federal Register specifying the revised time periods and the rationale for the reduction.

(c) Other. Any variance from the requirements of this part, other than as provided by paragraphs (a) and (b) of this section, must be soundly based on the interests of national security or the public health, safety, or welfare and must have the advance written approval of the Secretary; however, the Secretary is not authorized to waive or grant a variance from any requirement of the CEQ Regulations (except as provided for in those regulations). If the Secretary determines that a variance from the requirements of this part is within his/her authority to grant and is necessary, DOE shall publish a notice in the Federal Register specifying the variance granted and the reasons.
