(a) To implement the provisions of the National Environmental Policy Act (NEPA), 42 U.S.C. 4321 et seq., the Council on Environmental Quality Regulations for Implementing the Procedural Provisions of NEPA, 40 CFR 1500-1508, and the Department of Defense Instruction on Environmental Planning and Analysis, DODINST 4715.9, and to assign responsibilities within the Department of the Navy (DON) for preparation, review, and approval of environmental documents prepared under NEPA.

(b) The policies and responsibilities set out in this part apply to the DON, including the Office of the Secretary of the Navy, and Navy and Marine Corps commands, operating forces, shore establishments, and reserve components. This part is limited to the actions of these elements with environmental effects in the United States, its territories, and possessions.

(a) Action proponent. The commander, commanding officer, or civilian director of a unit, activity, or organization who initiates a proposal for action, as defined in 40 CFR 1508.23, and who has command and control authority over the action once it is authorized. For some actions, the action proponent will also serve as the decision-making authority for that action. In specific circumstances, the action proponent and decision maker may be identified in Navy Regulations, other SECNAV Instructions, operational instructions and orders, acquisition instructions, and other sources which set out authority and responsibility within the DON.

(b) Environmental Impact Statement (EIS). An environmental document prepared according to the requirements of Council on Environmental Quality (CEQ) regulations (40 CFR parts 1500-1508) for a major action that will have a significant effect on the quality of the human environment.

(c) Environmental Assessment (EA). A concise document prepared according to the requirements of 40 CFR parts 1500-1508 that briefly provides sufficient evidence and analysis for determining whether to prepare an EIS. An EA aids compliance with NEPA when no EIS is necessary and facilitates preparation of an EIS when one is necessary.

(d) Categorical Exclusion (CATEX). A published category of actions that do not individually or cumulatively have a significant impact on the human environment under normal circumstances, and, therefore, do not require either an environmental assessment or an environmental impact statement.

(e) Record of Decision (ROD). An environmental document signed by an appropriate official of the DON. A ROD sets out a concise summary of the final decision and selected measures for mitigation (if any) of adverse environmental impacts of the alternative chosen from those considered in an EIS.

(f) Finding of No Significant Impact (FONSI). A document that sets out the reasons why an action not otherwise categorically excluded will not have a significant impact on the human environment, and for which an EIS will not therefore be prepared. A FONSI will include the EA or a summary of it and shall note any other environmental documents related to it. A FONSI may be one result of review of an EA.

(a) It is the DON policy regarding NEPA, consistent with its mission and regulations and the environmental laws and regulations of the United States, to:

(1) Initiate the NEPA processes at the earliest possible time to be an effective decision making tool in the course of identifying a proposed action.

(2) Develop and carefully consider a reasonable range of alternatives for achieving the purpose(s) of proposed actions.

(3) Assign responsibility for preparation of action specific environmental analysis under NEPA to the action proponent. The action proponent should understand the plans, analyses, and environmental documents related to that action.

(b) NEPA is intended to ensure that environmental issues are fully considered and incorporated into the Federal decision making process. Consequently, actions for which the DON has no decision-making authority and no discretion in implementing the action, such as those carried out under a non discretionary mandate from Congress (e.g., congressional direction to transfer Federal property to a particular entity for a particular purpose that leaves DON no discretion in how the transfer will be implemented) or as an operation of law (e.g., reversionary interests in land recorded at the time the property was obtained and that provide no discretion in whether to trigger the reversion or how the reversion will be implemented), require no analysis or documentation under NEPA or its implementing regulations.

(a) The Assistant Secretary of the Navy (Installations and Environment) (ASN (I&E)) shall:

(1) Act as principal liaison with the Office of the Secretary of Defense, the Council on Environmental Quality, the Environmental Protection Agency, other Federal agencies, Congress, state governments, and the public with respect to significant NEPA matters.

(2) Direct the preparation of appropriate environmental analysis and documentation and, with respect to those matters governed by SECNAV Instruction 5000.2 series, advise the Assistant Secretary of the Navy (Research Development and Acquisition) (ASN (RD&A)) concerning environmental issues and the appropriate level of environmental analysis and NEPA documentation needed in any particular circumstance.

(3) Except for proposed acquisition-related actions addressed in paragraph (b)(2) of this section, review, sign, and approve for publication, as appropriate, documents prepared under NEPA.

(4) Establish and publish a list of categorical exclusions for the DON.

(b) The Assistant Secretary of the Navy (Research, Development and Acquisition (ASN (RD&A)) shall, in accordance with SECNAV Instruction 5000.2 series:

(1) Ensure that DON acquisition programs, research programs, and procurements comply with NEPA.

(2) Review, sign, and approve for publication, as appropriate, environmental documents prepared under NEPA for proposed acquisition or research and development related actions.

(c) The General Counsel of the Navy and the Judge Advocate General of the Navy shall:

(1) Ensure that legal advice for compliance with environmental planning requirements is available to all decision-makers.

(2) Advise the Secretary of the Navy, the Chief of Naval Operations, and the Commandant of the Marine Corps as to the legal requirements that must be met, and the conduct and disposition of all legal matters arising in the context of environmental planning.

(d) The Chief of Naval Operations (CNO) and the Commandant of the Marine Corps (CMC) shall:

(1) Implement effective environmental planning throughout their respective services.

(2) Prepare and issue instructions or orders to implement environmental planning policies of the DON. Forward proposed CNO/CMC environmental planning instructions or orders to ASN (I&E) and, when appropriate, ASN (RD&A) for review and comment prior to issuance.

(3) Make decisions on environmental assessments as to whether a Finding of No Significant Impact is appropriate or preparation of an environmental impact statement is required.

(4) Ensure that subordinate commands establish procedures for implementing mitigation measures described in NEPA documents.

(5) Provide coordination as required for the preparation of NEPA documents for actions initiated by non-DON/DOD entities, state or local agencies and/or private individuals for which service involvement may be reasonably foreseen.

(6) Bring environmental planning matters that involve controversial issues or which may affect environmental planning policies or their implementation to the attention of ASN (I&E) and, where appropriate, ASN (RD&A) for coordination and determination.

(7) Notify ASN (I&E), and when appropriate, ASN (RD&A) of any proposed EIS, and of any EA that may involve potentially sensitive public interest issues. EIS notification shall occur prior to commencing NEPA document preparation or receiving any public or regulatory agency involvement. EA notification shall be made as soon as it becomes apparent that potentially sensitive public issues are involved.

(a) The fact that a proposed action is of a classified nature does not relieve the proponent of the action from complying with NEPA and the CEQ regulations. Therefore, environmental documents shall be prepared, safeguarded and disseminated in accordance with the requirements applicable to classified information. When feasible, these documents shall be organized in such a manner that classified portions are included as appendices so that unclassified portions can be made available to the public. Review of classified NEPA documentation will be coordinated with the Environmental Protection Agency (EPA) to fulfill requirements of section 309 of the Clean Air Act (42 U.S.C. 7609 et seq.).

(b) It should be noted that a classified EA/EIS serves the same “informed decisionmaking” purpose as does a published unclassified EA/EIS. Even though the classified EA/EIS does not undergo general public review and comment, it must still be part of the information package to be considered by the decisionmaker for the proposed action. The content of a classified EA/EIS (or the classified portion of a public EA/EIS) will therefore meet the same content requirements applicable to a published unclassified EA/EIS.

(a) An EIS must be prepared for proposed major Federal actions that will have significant impacts on the human environment. The agency decision in the case of an EIS is reflected in a ROD.

(b) Where a proposed major Federal action has the potential for significantly affecting the human environment, but it is not clear whether the impacts of that particular action will in fact be significant, or where the nature of an action precludes use of a categorical exclusion, an EA may be used to assist the agency in determining whether to prepare an EIS. If the agency determination in the case of an EA is that there is no significant impact on the environment, the findings will be reflected in a FONSI. If the EA determines that the proposed action is likely to significantly affect the environment (even after mitigation), then an EIS will be prepared. An EA also may be used where it otherwise will aid compliance with NEPA.

(c) CEQ regulations (40 CFR 1508.18(a)) define major federal actions subject to evaluation under NEPA to include, among other things, “new and continuing activities”. The term new activities is intended to encompass future actions, i.e., those which are not ongoing at the time of the proposal. The term continuing activities which may necessitate the preparation of a NEPA document will be applied by the Department of Navy to include activities which are presently being carried out in fulfillment of the Navy mission and function, including existing training functions, where:

(1) The currently occurring environmental effects of which have not been previously evaluated in a NEPA document, and there is a discovery that substantial environmental degradation is occurring, or is likely to occur, as a result of ongoing operations (e.g., a discovery that significant beach erosion is occurring as a result of continuing amphibious exercises, new designation of wetland habitat, or discovery of an endangered species residing in the area of the activity), or

(2) There is a discovery that the environmental effects of an ongoing activity are significantly and qualitatively different or more severe than predicted in a NEPA document prepared in connection with the commencement of the activity.

(d) Where emergency circumstances require immediate action, for the protection of lives and for public health and safety, which could result in significant harm to the environment, the activity Commanding Officer or his designee shall report the emergency action to CNO (OP-44E)/CMC (LFL) who will facilitate the appropriate consultation with CEQ as soon as practicable.

(e) A categorical exclusion (CATEX), as defined and listed in this part and 40 CFR 1508.4, may be used to satisfy NEPA, eliminating the need for an EA or an EIS. Extraordinary circumstances are those circumstances for which the DON has determined that further environmental analysis may be required because an action normally eligible for a CATEX may have significant environmental effects. The presence of one or more of the extraordinary circumstances listed in paragraph (e)(1) of this section does not automatically preclude the application of a CATEX. A determination of whether a CATEX is appropriate for an action, even if one or more extraordinary circumstances are present, should focus on the action's potential effects and consider the environmental significance of those effects in terms of both context (consideration of the affected region, interests, and resources) and intensity (severity of impacts).

(1) Before applying a CATEX, the decision maker must consider whether the proposed action would individually or cumulatively:

(i) Adversely affect public health or safety;

(ii) Involve effects on the human environment that are highly uncertain, involve unique or unknown risks, or which are scientifically controversial;

(iii) Establish precedents or make decisions in principle for future actions that have the potential for significant impacts;

(iv) Threaten a violation of Federal, State, or local environmental laws applicable to the DON; or

(v) Involve an action that may:

(A) Have more than an insignificant or discountable effect on federally protected species under the Endangered Species Act or have impacts that would rise to the level of requiring an Incidental Take Authorization under the Marine Mammal Protection Act irrespective of whether one is procured;

(B) Have an adverse effect on coral reefs or on federally designated wilderness areas, wildlife refuges, marine sanctuaries and monuments, or parklands;

(C) Adversely affect the size, function, or biological value of wetlands and is not covered by a general (nationwide, regional, or state) permit;

(D) Have an adverse effect on archaeological resources or resources listed or determined to be eligible for listing on the National Register of Historic Places (including, but not limited to, ships, aircraft, vessels, and equipment) where compliance with Section 106 of the National Historic Preservation Act has not been resolved through an agreement executed between the DON and the appropriate historic preservation office and other appropriate consulting parties; or

(E) Result in an uncontrolled or unpermitted release of hazardous substances or require a conformity determination under standards in 40 CFR part 93, subpart B (the Clean Air Act General Conformity Rule).

(2) If a decision is made to apply a CATEX to a proposed action that is more than administrative in nature, the decision must be formally documented per existing Navy and Marine Corps policy. For actions with a documented CATEX where one or more extraordinary circumstances are present, a copy of the executed CATEX decision document (e.g., Record of CATEX or Decision Memorandum) must be forwarded for review to Navy Headquarters or Marine Corps Headquarters, as appropriate, before the action is implemented. With the exception of actions that fall under paragraph (e)(1)(v)(A) of this section, the requirement to send the documented CATEX to headquarters for review will end on January 6, 2022.

(f) Subject to the criteria in paragraph (e) of this section, the following categories of actions are excluded from further analysis under NEPA. The CNO and CMC shall determine whether a decision to forego preparation of an EA or EIS on the basis of one or more categorical exclusions must be documented in an administrative record and the format for such record.

(1) Routine fiscal and administrative activities, including administration of contracts;

(2) Routine law and order activities performed by military personnel, military police, or other security personnel, including physical plant protection and security;

(3) Routine use and operation of existing facilities, laboratories, and equipment;

(4) Administrative studies, surveys, and data collection;

(5) Issuance or modification of administrative procedures, regulations, directives, manuals, or policy;

(6) Military ceremonies;

(9) Training of an administrative or classroom nature;

(10) Routine personnel actions;

(11) Routine movement of mobile assets (such as ships, submarines, aircraft, and ground assets for repair, overhaul, dismantling, disposal, homeporting, home basing, temporary reassignments; and training, testing, or scientific research) where no new support facilities are required;

(12) Routine procurement, management, storage, handling, installation, and disposal of commercial items, where the items are used and handled in accordance with applicable regulations (e.g., consumables, electronic components, computer equipment, pumps);

(13) Routine recreational and welfare activities;

(14) Alterations of and additions to existing buildings, facilities, and systems (e.g., structures, roads, runways, vessels, aircraft, or equipment) when the environmental effects will remain substantially the same and the use is consistent with applicable regulations;

(15) Routine movement, handling, and distribution of materials, including hazardous materials and wastes that are moved, handled, or distributed in accordance with applicable regulations;

(16) New activities conducted at established laboratories and plants (including contractor-operated laboratories and plants) where all airborne emissions, waterborne effluent, external ionizing and non-ionizing radiation levels, outdoor noise, and solid and bulk waste disposal practices are in compliance with existing applicable Federal, state, and local laws and regulations;

(17) Studies, data, and information gathering that involve no permanent physical change to the environment (e.g., topographic surveys, wetlands mapping, surveys for evaluating environmental damage, and engineering efforts to support environmental analyses);

(18) Temporary placement and use of simulated target fields (e.g., inert mines, simulated mines, or passive hydrophones) in fresh, estuarine, and marine waters for the purpose of non-explosive military training exercises or research, development, test, and evaluation;

(19) Installation and operation of passive scientific measurement devices (e.g., antennae, tide gauges, weighted hydrophones, salinity measurement devices, and water quality measurement devices) where use will not result in changes in operations tempo and is consistent with applicable regulations;

(20) Short-term increases in air operations up to 50 percent of the typical operation rate, or increases of 50 operations per day, whichever is greater. Frequent use of this CATEX at an installation requires further analysis to determine there are no cumulative impacts;

(21) Decommissioning, disposal, or transfer of naval vessels, aircraft, vehicles, and equipment when conducted in accordance with applicable regulations, including those regulations applying to removal of hazardous materials;

(22) Non-routine repair and renovation, and donation or other transfer of structures, vessels, aircraft, vehicles, landscapes, or other contributing elements of facilities listed or eligible for listing on the National Register of Historic Places;

(23) Hosting or participating in public events (e.g., air shows, open houses, Earth Day events, and athletic events) where no permanent changes to existing infrastructure (e.g., road systems, parking, and sanitation systems) are required to accommodate all aspects of the event;

(24) Military training conducted on or over nonmilitary land or water areas, where such training is consistent with the type and tempo of existing non-military airspace, land, and water use (e.g., night compass training, forced marches along trails, roads, and highways, use of permanently established ranges, use of public waterways, or use of civilian airfields);

(25) Transfer of real property from the DON to another military department or to another Federal agency;

(26) Receipt of property from another Federal agency when there is no anticipated or proposed substantial change in land use;

(28) Disposal of excess easement interests to the underlying fee owner;

(29) Initial real estate in grants and out grants involving existing facilities or land with no significant change in use (e.g., leasing of federally owned or privately owned housing or office space, and agricultural out leases);

(30) Renewals and minor amendments of existing real estate grants for use of Government-owned real property where no significant change in land use is anticipated;

(31) Land withdrawal continuances or extensions that establish time periods with no significant change in land use;

(32) Grants of license, easement, or similar arrangements for the use of existing rights-of-way or incidental easements complementing the use of existing rights-of-way for use by vehicles (not to include significant increases in vehicle loading); electrical, telephone, and other transmission and communication lines; water, wastewater, storm water, and irrigation pipelines, pumping stations, and facilities; and for similar utility and transportation uses;

(33) New construction that is similar to or compatible with existing land use (i.e., site and scale of construction are consistent with those of existing adjacent or nearby facilities) and, when completed, the use or operation of which complies with existing regulatory requirements (e.g., a building within a cantonment area with associated discharges and runoff within existing handling capacities). The test for whether this CATEX can be applied should focus on whether the proposed action generally fits within the designated land use of the proposed site;

(34) Demolition, disposal, or improvements involving buildings or structures when done in accordance with applicable regulations including those regulations applying to removal of asbestos, PCBs, and other hazardous materials;

(35) Acquisition, installation, modernization, repair, or operation of utility (including, but not limited to, water, sewer, and electrical) and communication systems (including, but not limited to, data processing cable and similar electronic equipment) that use existing rights of way, easements, distribution systems, and facilities;

(36) Decisions to close facilities, decommission equipment, or temporarily discontinue use of facilities or equipment, where the facility or equipment is not used to prevent or control environmental impacts;

(39) Pre-lease upland exploration activities for oil, gas, or geothermal reserves, (e.g., geophysical surveys);

(40) Installation of devices to protect human or animal life (e.g., raptor electrocution prevention devices, fencing to restrict wildlife movement onto airfields, and fencing and grating to prevent accidental entry to hazardous areas);

(41) Reintroduction of endemic or native species (other than endangered or threatened species) into their historic habitat when no substantial site preparation is involved;

(42) Temporary closure of public access to DON property to protect human or animal life;

(43) Routine testing and evaluation of military equipment on a military reservation or an established range, restricted area, or operating area; similar in type, intensity, and setting, including physical location and time of year, to other actions for which it has been determined, through NEPA analysis where the DON was a lead or cooperating agency, that there are no significant impacts; and conducted in accordance with all applicable standard operating procedures protective of the environment;

(44) Routine military training associated with transits, maneuvering, safety and engineering drills, replenishments, flight operations, and weapons systems conducted at the unit or minor exercise level; similar in type, intensity, and setting, including physical location and time of year, to other actions for which it has been determined, through NEPA analysis where the DON was a lead or cooperating agency, that there are no significant impacts; and conducted in accordance with all applicable standard operating procedures protective of the environment;

(45) Natural resources management actions undertaken or permitted pursuant to agreement with or subject to regulation by Federal, state, or local organizations having management responsibility and authority over the natural resources in question, including, but not limited to, prescribed burning, invasive species actions, timber harvesting, and hunting and fishing during seasons established by state authorities pursuant to their state fish and game management laws. The natural resources management actions must be consistent with the overall management approach of the property as documented in an Integrated Natural Resources Management Plan (INRMP) or other applicable natural resources management plan;

(46) Minor repairs in response to wildfires, floods, earthquakes, landslides, or severe weather events that threaten public health or safety, security, property, or natural and cultural resources, and that are necessary to repair or improve lands unlikely to recover to a management-approved condition (i.e., the previous state) without intervention. Covered activities must be completed within one year following the event and cannot include the construction of new permanent roads or other new permanent infrastructure. Such activities include, but are not limited to: Repair of existing essential erosion control structures or installation of temporary erosion controls; repair of electric power transmission infrastructure; replacement or repair of storm water conveyance structures, roads, trails, fences, and minor facilities; revegetation; construction of protection fences; and removal of hazard trees, rocks, soil, and other mobile debris from, on, or along roads, trails, or streams;

(47) Modernization (upgrade) of range and training areas, systems, and associated components (including, but not limited to, targets, lifters, and range control systems) that support current testing and training levels and requirements. Covered actions do not include those involving a substantial change in the type or tempo of operation, or the nature of the range (i.e., creating an impact area in an area where munitions had not been previously used);

(48) Revisions or updates to INRMPs that do not involve substantially new or different land use or natural resources management activities and for which an EA or EIS was previously prepared that does not require supplementation pursuant to 40 CFR 1502.9(c)(1); and

(49) DON actions that occur on another Military Service's property where the action qualifies for a CATEX of that Service, or for actions on property designated as a Joint Base or Joint Region that would qualify for a CATEX of any of the Services included as part of the Joint Base or Joint Region. If the DON action proponent chooses to use another Service's CATEX to cover a proposed action, the DON must obtain written confirmation the other Service does not object to using its CATEX to cover the DON action. The DON official making the CATEX determination must ensure the application of the CATEX is appropriate and that the DON's proposed action was of a type contemplated when the CATEX was established by the other Service. Use of this CATEX requires preparation of a Record of CATEX or Decision Memorandum.

(a) The timing of the preparation, circulation, submission and public availability of environmental documents is important in achieving the purposes of NEPA. Therefore, the NEPA process shall begin as early as possible in the decisionmaking process.

(b) The EPA publishes a weekly notice in the Federal Register of environmental impact statements filed during the preceding week. The minimum time periods set forth below shall be calculated from the date of publication of notices in the Federal Register. No decision on the proposed action may take place until the later of the following dates:

(1) Ninety days after publication of the notice of availability for a draft environmental impact statement (DEIS). Draft statements shall be available to the public for 15 days prior to any public hearing on the DEIS (40 CFR 1506.6(c)(2)).

(2) Thirty days after publication of the notice of availability for a final environmental impact statement (FEIS). If the FEIS is available to the public within ninety days from the availability of the DEIS, the minimum thirty day period and the minimum nintey day period may run concurrently. However, not less than 45 days from publication of notice of filing shall be allowed for public comment on draft statements prior to filing of the FEIS (40 CFR 1506.10(c)).

As soon as practicable after the decision to prepare an EIS is made, an early and open process called “scoping” shall be used to determine the scope of issues to be addressed and to identify the significant issues to be analyzed in depth related to the proposed action (40 CFR 1501.7). This process also serves to deemphasize insignificant issues, narrowing the scope of the EIS process accordingly (40 CFR 1500.4(g)). Scoping results in the identification by the proponent of the range of actions, alternatives, and impacts to be considered in the EIS (40 CFR 1508.25). For any action, this scope may depend on the relationship of the proposed action to other existing environmental documentation.

(a) Environmental documentation and analyses required by this rule should be integrated as much as practicable with any environmental studies, surveys and impact analyses required by other environmental review laws and executive orders (40 CFR 1502.25). When a cost-benefit analysis has been prepared in conjunction with an action which also requires a NEPA analysis, the cost-benefit analysis shall be integrated into the environmental documentation.

(b) CEQ regulations encourage the use of tiering whenever appropriate to eliminate repetitive discussions of the same issues and to focus on the actual issues ripe for discussion at each level of environmental review (40 CFR 1502.20). Tiering is accomplished through the preparation of a broad programmatic environmental impact statement discussing the impacts of a wide ranging or long term stepped program followed by narrower statements or environmental assessments concentrating solely on issues specific to the analysis subsequently prepared (40 CFR 1508.28).

(1) Appropriate use of tiering: Tiering is appropriate when it helps the lead agency to focus on issues which are ripe for decision and exclude from consideration issues already decided or not yet ripe. (40 CFR 1508.28(b).) The sequence of statements or analyses is:

(i) From a broad program, plan, or policy environmental impact statement (not necessarily site specific) to a subordinate/smaller scope program, plan, or policy statement or analysis (usually site specific) (40 CFR 1508.28 (a)).

(ii) From an environmental impact statement on a specific action at an early stage (such as need and site selection) to a supplement (which is preferred) or a subsequent statement or analysis at a later stage (such as environmental mitigation) (40 CFR 1508.28(b)).

(iii) In addition to the discussion required by these regulations for inclusion in environmental impact statements, the programmatic environmental impact statement shall also discuss:

(A) A description of the subsequent stages or sites that may ultimately be proposed in as much detail as presently possible;

(B) All of the implementing factors of the program that can be ascertained at the time of impact statement preparation;

(C) All of the environmental impacts that will result from establishment of the overall program itself that will be similar for subsequent stages or sites as further implementation plans are proposed; and

(D) All of the appropriate mitigation measures that will be similarly proposed for subsequent stages or sites.

(iv) The analytical document used for stage or site specific analysis subsequent to the programmatic environmental impact statement shall also be an environmental impact statement when the subsequent tier itself may have a significant impact on the quality of the human environment or when an impact statement is otherwise required. Otherwise, it is appropriate to document the tiered analysis with an environmental assessment to fully assess the need for further documentation or whether a FONSI would be appropriate.

(2) [Reserved]

Close and harmonious planning relations with local and regional agencies and planning commissions of adjacent cities, counties, and states, for cooperation and resolution of mutual land use and environment-related problems should be established. Additional coordination may be obtained from state and area-wide planning and development “clearinghouses”. These are agencies which have been established pursuant to Executive Order 12372 of July 14, 1982 (3 CFR, 1982 Comp., p. 197). The clearinghouses serve a review and coordination function for Federal activities and the proponent may gain insights on other agencies' approaches to environmental assessments, surveys, and studies in relation to any current proposal. The clearinghouses would also be able to assist in identifying possible participants in scoping procedures for projects requiring an EIS.

The importance of public participation (40 CFR 1501.4(b)) in preparing environmental assessments is clearly recognized and it is recommended that commands proposing an action develop a plan to ensure appropriate communication with affected and interested parties. The command Public Affairs Office can provide assistance with developing and implementing this plan. In determining the extent to which public participation is practicable, the following are among the factors to be weighed by the command:

(a) The magnitude of the environmental considerations associated with the proposed action;

(b) The extent of anticipated public interest; and

(c) Any relevant questions of national security and classification.

(a) The ASN (I&E) may delegate his/her responsibilities under this instruction for review, approval and/or signature of EISs and RODs to appropriate Executive Schedule/Senior Executive Service civilians or flag/general officers. ASN (I&E), CNO, and CMC may delegate all other responsibilities assigned in this instruction as deemed appropriate.

(b) The ASN (RD&A) delegation of authority for approval and signature of documents under NEPA is contained in SECNAV Instruction 5000.2 series, which sets out policies and procedures for acquisition programs.

(c) Previously authorized delegations of authority are continued until revised or withdrawn.
