Overview

DOE began operations on October 1, 1977. The functions of DOE’s predecessor organizations (the Energy Research and Development Administration, Federal Energy Administration, and Federal Power Commission) and some energy-related functions of other federal agencies were transferred to DOE under the Department of Energy Organization Act.

The Council on Environmental Quality (CEQ) NEPA regulations (40 CFR Parts 1500-1508) became binding on federal agencies on July 30, 1979. The regulations stated (§1505.1) that agencies “shall adopt … implementing procedures under section 102(2) [of NEPA] to achieve the requirements of sections 101 and 102(1).” In 1979, DOE established 10 CFR Part 1021 through a rulemaking that adopted the CEQ NEPA regulations. From 1979 to 1992, DOE promulgated its NEPA implementing procedures as “guidelines,” which also listed classes of actions that normally do not have potential to cause significant environmental impacts (categorical exclusions or “CXs”) and those that normally require preparation of an EA or EIS. In 1992, DOE revoked the DOE NEPA guidelines and replaced them with revised and expanded DOE NEPA regulations at 10 CFR Part 1021. 

Beginning in 1978, an order, National Environmental Policy Act Compliance Program, established DOE’s internal assignment of responsibilities for complying with NEPA and associated implementing regulations and guidelines. Each revision of the DOE NEPA order cancelled the previous version. In December 2017, DOE Policy 451.1 cancelled the DOE NEPA order.

Listed below, in chronological order, are links to documents showing the development of DOE's NEPA regulations, internal procedures, and policies. "Archived" indicates that the document is not currently applicable.

1990-02-02 Policy: Secretary of Energy Notice SEN 15 90, National Environmental Policy Act (archived)

This Secretary of Energy Notice directed revisions to DOE NEPA compliance procedures “to correct the deficiencies and accomplish the objectives discussed in” a “10 point initiative to ensure that all Departmental activities are carried out in full compliance with the letter and spirit of environmental statutes and regulations.”

The notice directed changes in DOE NEPA procedures and authorities to be incorporated in a revision of the DOE NEPA Order. The notice ended use of a “memorandum to file” (under DOE O 5440.1B, a determination “that a proposed action, although not categorically excluded in [the DOE NEPA guidelines], clearly will not have significant environmental effects and therefore does not warrant preparation of an [EA or EIS]”). Other changes provided for the Assistant Secretary for Environment, Safety and Health to review determinations for proposals listed in Section D of the guidelines, make EA and EIS determinations for proposals not listed in Section D, and approve EAs and EISs; require each headquarters office with NEPA responsibilities and each operations office to designate a NEPA Compliance Officer; require a mitigation action plan for implementing any commitments made in an EIS/Record of Decision or an EA/Finding of No Significant Impact for which the FONSI is based, in significant part, on the mitigation commitment.

The notice directed revising the DOE NEPA guidelines and reissuing the guidelines as regulations. Changes to be incorporated in the rule revision included: revising and expanding CXs that minimize “the necessity for subjective judgment”; eliminating a “catch all” CX (“Actions that are substantially the same as other actions for which the environmental impacts have already been assessed in a NEPA document and determined by DOE to be clearly insignificant and where such assessment is still valid”); requiring a public scoping meeting for every EIS and a public hearing on every draft EIS; developing and updating site wide EISs; notifying host states and, as appropriate, adjacent states of determinations to prepare a NEPA document and providing a review opportunity before DOE approval of an EA (broadened during the rulemaking to include tribes); making a supplement analysis available to the public; requiring a mitigation plan for certain EISs and EAs.

SEN 15 90 was cancelled via DOE N 251.18 (1996 11 04), following incorporation of provisions into the DOE NEPA regulations (57 FR 15122; 1992-04-24) and order (DOE O 5440.1D; 1991-02-22).

1994-06-13 Policy: Secretarial Policy Statement on the National Environmental Policy Act (archived)

The policy statement directed changes in DOE NEPA procedures “to streamline the NEPA process, minimize the cost and time for document preparation and review, emphasize teamwork, and make the process more useful to decision makers and the public.” 

Among other changes, the policy directed the delegation of full authorities for EAs to Heads of Field Organizations; instituted an annual NEPA planning summary; initiated NEPA guidance on contract statements of work, public participation, and recommendations for the preparation of EAs and EISs; established a requirement to designate a DOE NEPA Document Manager for each project requiring NEPA review; provided for reliance on the CERCLA process to address NEPA values and public participation for certain actions; initiated a NEPA contracting quality improvement team and stated provisions for contract reform, such as a requirement to evaluate contractor performance; and established a NEPA metrics program and quarterly summary on lessons learned. 

The policy statement was implemented through delegations of EA authorities, issuance of guidance documents, revision of the DOE NEPA Order (DOE O 451.1; 1995-09-11), and initiation of DOE NEPA Lessons Learned Quarterly Report in December 1994.
