SUPPLEMENTARY INFORMATION:

Purpose and Need for Action

    One of the most urgent and difficult technical tasks facing the DOE 
is to assess the effects of aging on the weapons that remain in the 
nation's nuclear stockpile, and to ensure the continuing safety of 
those weapons. Because the President has decided not to build any new 
nuclear weapons for the foreseeable future, but instead to continue to 
rely upon a smaller stockpile of existing but aging weapons as a 
nuclear deterrent, DOE must ensure that the weapons remaining in the 
stockpile are safe, secure and reliable. Under the Atomic Energy Act, 
this mission rests with DOE and essentially requires DOE to certify 
that the weapons will not accidentally detonate during storage and 
handling, that the weapons would thwart any attempts for unauthorized 
use, and that they would function as designed in the event of 
authorized use.
    To fulfill this mission, DOE needs to collect diagnostic 
information regarding the condition of the weapons which remain in the 
enduring stockpile. Some of these weapons are approaching the end of 
their design life, and DOE is not certain how they may be affected by 
the aging process. One important type of information that is currently 
lacking concerns the three-dimensional condition of the various 
internal components of aging weapons. These are often shielded by thick 
and dense materials. Multiple view hydrodynamic testing (experiments to 
look at the flow of adjacent materials as they are driven by high 
explosives) and dynamic testing (experiments to study other effects of 
high explosives), combined with computer modeling, provide the only 
means of obtaining this data in the absence of nuclear testing. The 
President has endorsed hydrodynamic testing as the preferred means of 
conducting experiments in support of stockpile stewardship and 
maintenance. Hydrodynamic testing has become more important since the 
United States moratorium on nuclear testing was extended. A future 
Comprehensive Test Ban Treaty, moreover, would foreclose the 
acquisition of additional performance and safety data through nuclear 
testing.

Proposed Action

    DARHT would be a specialized high energy X-ray machine that would 
take three-dimensional, sequential and high-resolution X-ray pictures 
of the dynamic behavior of dense materials that are being shocked and 
compressed by high explosives. DARHT would be used to evaluate the 
nonnuclear behavior of nuclear weapons components and would provide the 
nation with a significantly improved diagnostic capability to evaluate 
and assess the safety and reliability of the existing nuclear weapons 
stockpile. DARHT would consist of an existing support lab, a new firing 
site, and the necessary infrastructure, all located at Technical Area 
15 at LANL. DARHT would be used to detonate high explosives, and to use 
very high-speed, tightly-focused radiographic (X-ray) photography to 
determine the motions (dynamic experiments) or flow (hydrodynamic 
tests) of the explosive-driven materials. Two X-ray machines at right 
angles to each other (dual-axis lines of sight) would be powered by two 
16 million electron volt (MeV) electron accelerators, each housed in a 
building about 225 feet long. By using two machines, DARHT would be 
able to provide three-dimensional, sequential information on 
occurrences within millionths of a second during a test. The 
accelerators' small beam size would allow DARHT to provide a very high-
quality resolution of the radiographic image. This resolution is 
necessary to resolve the fine details of the material flowing in these 
experiments.
    DARHT experiments would variously involve radioactive materials 
(primarily depleted uranium), beryllium and other hazardous materials, 
and other metals. Additionally, experiments involving plutonium 
contained in steel vessels may be conducted. DARHT would not test 
materials that could result in nuclear yield, or a nuclear detonation. 
Experiments at DARHT would be expected to result in metal fragments and 
other airborne debris being deposited up to 750 meters from the open-
air explosives testing (standard operating procedures would require the 
evacuation of this area before any experiments were conducted).
    In addition to testing the nonnuclear behavior of nuclear weapons 
components, DARHT would be used to evaluate conventional weapons 
systems, explosives-driven materials for non-weapons uses, and high-
velocity impact phenomena. The facility would also be used to support 
non-proliferation and counter-proliferation efforts, such as 
experiments intended to disable a terrorist-designed or proliferant-
designed nuclear weapon. Although DARHT could be used to collect 
information relevant to the design of new weapons, no new weapons are 
anticipated to be designed in the foreseeable future.
    Design of DARHT began in the early 1980's. Memoranda to File, 
describing the environmental impacts of constructing and operating 
DARHT, were completed in 1983 and 1987. DARHT construction began in 
1988 with the Radiographic Support Laboratory, which was completed in 
1990. The Radiographic Support Laboratory is currently being used to 
support the development of the accelerator equipment that is planned to 
be used in DARHT. In May 1994, DOE began construction of the 
Hydrodynamic Firing Site. Approximately 20 percent of the Hydrodynamic 
Firing Site construction work (e.g., site preparation, foundation 
pouring) has been completed. Current schedules call for the 
Hydrodynamic Firing Site construction to be completed, and the first X-
ray machine to be operating, in 1997 at a cost of approximately $86 
million, and the second X-ray machine, if approved, would begin 
operation in 2000. The total estimated project cost of DARHT in its 
final two-axis configuration is $124 million; to date, approximately 
$44 million has been spent or obligated on the project.
    In response to public concern, the DOE has decided to prepare this 
EIS at this time to allow for a full dialogue between DOE and the 
State, tribes, other agencies and the general public regarding the 
environmental impacts of completing and operating DARHT, and the 
impacts of other alternatives. The EIS will also assist in ensuring 
that appropriate mitigation measures are developed if DARHT is 
completed and put into operation. Construction and related work on the 
facility will continue during the preparation of the EIS.

Proposed Alternatives

    DOE has tentatively identified the following alternatives for 
analysis in the EIS and seeks public comment on their adequacy, 
inclusiveness, and reasonableness:

(1) Proposed action

    Under this alternative, DOE would complete construction and operate 
the DARHT facility as currently planned. This alternative would provide 
a state-of-the-art diagnostic capability for ensuring the safety, 
security and reliability of the aging nuclear weapons stockpile. If 
DARHT becomes operational, operation of the Pulsed High Energy 
Radiation Machine Emitting X-Rays (PHERMEX) facility, an existing 
facility at LANL also located at Technical Area 15, near the DARHT 
site, will be phased out.

(2) No Action (status quo) Alternative

    Under this alternative, DARHT would not be completed and DOE would 
continue to operate the Pulsed High Energy Radiation Machine Emitting 
X-Rays and the Flash X-Ray facility at the Department's Lawrence 
Livermore National Laboratory Site 300 located near Livermore, 
California. The Pulsed High Energy Radiation Machine Emitting X-Rays, a 
single-axis radiographic facility, was built in the mid-1960's and has 
been used continuously since that time. It uses a pulsed power 
accelerator to power the X-ray machine, and does not have the small 
beam size (tight focus) planned for DARHT, thereby precluding the high-
resolution images that DARHT would provide. Flash X-Ray, also a single-
axis radiographic facility, was built in 1982 and has been used 
continuously since that time. It uses a linear induction accelerator to 
power the X-ray machine and also does not have the small beam size 
planned for DARHT.

(3) Containment Alternative

    Under this alternative, DOE would modify the construction and/or 
operation of DARHT to contain some or all airborne emissions of 
fragments or other debris. Under one approach, the X-ray pictures would 
be taken through the walls of a containment vessel. Another approach 
would be to construct a building to enclose and contain the explosive 
experiments; X-ray pictures would be taken within the containment 
building. These two approaches may be considered separately or 
together, for some tests or for all tests.

(4) Institutional Control Alternative

    Under this alternative, DOE would complete and operate DARHT, but 
would limit use of the facility to exclude any applications involving 
experiments with plutonium.

(5) Single-Axis Alternative

    Under this alternative DOE would complete construction of the 
Hydrodynamic Firing Site but would operate only a single axis of DARHT 
with one accelerator. This alternative would provide an improved 
technical capability over present accelerators with a single view 
(i.e., the Pulsed High Energy Radiation Machine Emitting X-Rays and 
Flash X-Ray).

(6) Upgrade Alternative

    Under this alternative DOE would upgrade the present Pulsed High 
Energy Radiation Machine Emitting X-Rays capability with the new 
technology developed for DARHT.
    DOE does not intend, in this EIS, to analyze alternatives or issues 
beyond the construction and operation of DARHT that relate to the 
nation's nuclear weapons policies, the DOE mission of stockpile 
stewardship and management, the need for hydrodynamic testing or 
dynamic testing that are part of the stockpile stewardship and 
management program, the mission of LANL, or continued operation of 
other facilities at LANL. To the extent that these matters are under 
the purview of DOE, they will be considered in the Programmatic EIS on 
Stockpile Stewardship and Management or the LANL Sitewide EIS, as 
discussed below in the section on related NEPA reviews.

Proposed Issues

    The EIS will identify and analyze the direct, indirect and 
cumulative effects resulting from the completion and operation of 
DARHT. DOE has tentatively identified the following environmental and 
socioeconomic issues for consideration in the EIS and seeks public 
comment on the adequacy and inclusiveness of these issues:
     Natural ecosystems, including air quality, surface and 
groundwater quality, and plants and animals.
     Cultural resources, including archeological sites, 
historic resources, other facilities and infrastructure at LANL, and 
actual and potential uses of the site including Native American 
cultural, traditional and religious uses; DOE has previously identified 
Native American archeological sites in the vicinity of DARHT and has 
conducted mitigating activities.
     Economic impacts, including those from constructing, 
equipping and operating DARHT.
     Socioeconomic impacts, including any disproportionately 
high and adverse impacts on minority and low income populations.
     Health and safety impacts to on-site workers, other LANL 
personnel, local communities and tribes, and the general population of 
northern New Mexico.
     Other construction and operational impacts, such as 
transportation of people and materials.
     Waste management considerations, including the eventual 
decontamination and decommissioning of the facility after the end of 
its useful life (approximately 30 years).
     Health and safety, environmental, and other impacts 
related to the transport, storage and use of hazardous and radioactive 
materials and generation of X-ray radiation.
     Other relevant issues identified by DOE or the State, 
tribes, other agencies, or the public through this scoping process.

Related NEPA Reviews

    The Department is currently preparing to undertake two related NEPA 
reviews. The planned LANL Sitewide EIS (59 FR 40889, August 10, 1994) 
will consider the cumulative impacts of operations and planned 
activities foreseen within the next 5 to 10 years. The planned 
Stockpile Stewardship and Management Programmatic EIS (59 FR 54175, 
October 28, 1994) will evaluate activities required to maintain a high 
level of confidence in the safety, reliability, and performance of 
nuclear weapons in the absence of nuclear testing, and to be prepared 
to test weapons if so directed by the President.

Classified Material

    The Department will review classified material while preparing this 
EIS. Within the limits of classification, DOE will provide to the 
public as much information as possible. If DOE needs to generate 
classified material to explain the purpose and need, use, materials, or 
impacts from this project, that material will be segregated into a 
classified appendix.

Public Involvement Opportunities

    DOE will develop a stakeholder involvement plan to guide the public 
review aspects of this EIS. To assist with developing the stakeholder 
involvement plan, DOE requests suggestions by the public on how this 
EIS process should be conducted, including suggestions regarding the 
type, format and conduct of public involvement opportunities.
    Through this Notice, DOE formally invites the State, tribes, other 
government agencies and the public to comment on the scope of the EIS. 
DOE will offer informational briefings to tribal governments, local 
(county and municipal) governments, and the State of New Mexico.
    A second formal opportunity for comment will be provided after DOE 
issues the draft EIS, expected in mid-1995. Public hearings will be 
held in conjunction with that comment period. DOE will inform the 
State, tribes, local governments, other agencies and the general public 
of its final decisions at the time the Record of Decision is issued, 
expected in October 1995.
    In addition to formal opportunities for comment, any person may 
submit comments at any time during the NEPA review process; however, to 
ensure that comments are considered at specific points in the NEPA 
review, and to best assist DOE, the public is encouraged to comment 
during the formally established comment periods.
    Copies of DARHT design and other background documents, written 
comments, records of public meetings, and other materials related to 
the development and analyses of the EIS have been and are being placed 
in the Los Alamos National Laboratory Community Reading Room, 1450 
Central Avenue, Suite 101, Los Alamos, New Mexico 87544. For 
information on the availability of specific documents and hours of 
operation, please contact the reading room at (505)665-2127 or
