DEPARTMENT OF ENERGY
Draft Environmental Impact Statement for the Hanford Site Tank
Waste Remediation System, Richland, Washington
AGENCY: U.S. Department of Energy and Washington State Department of
Ecology.
ACTION: Notice of availability (NOA).
-----------------------------------------------------------------------
SUMMARY: The Department of Energy (DOE), in cooperation with the
Washington State Department of Ecology (Ecology), announces the
availability of the draft Environmental Impact Statement (EIS) for the
Hanford Site Tank Waste Remediation System (TWRS). The draft EIS
addresses DOE's proposed strategies and reasonable alternatives for
management and disposal of radioactive, hazardous, and mixed waste
currently or projected to be stored in 177 underground storage tanks
and in approximately 60 active and inactive miscellaneous underground
storage tanks that were associated with Hanford's tank farm operations.
The EIS also addresses the management and disposal of approximately
1,930 radioactive cesium and strontium capsules currently on loan or
stored at the Hanford Site, if the capsules are determined to have no
further beneficial use. The Hanford Site is located near Richland,
Washington. Ecology and DOE signed a Memorandum of Understanding on
February 15, 1994 to co-prepare this EIS.
DATES: DOE and Ecology invite all interested parties to submit written
comments concerning the draft EIS during a comment period ending May
28, 1996. Written comments should be postmarked by May 28, 1996.
Comments
[[Page 16472]]
postmarked after that date will be considered to the extent

SUPPLEMENTARY INFORMATION:
Background
DOE issued a Notice of Intent to prepare the Hanford Tank Waste
Remediation System EIS on January 23, 1994 (59 FR 4052). Thereafter,
DOE and Ecology held five public scoping meetings in five locations in
Washington and Oregon to obtain public comment on the scope of the EIS.
The document number for this draft EIS is DOE/EIS-0189-D. The draft
EIS was prepared in accordance with the requirements of the National
Environmental Policy Act of 1969 (NEPA); the Council on Environmental
Quality regulations implementing NEPA, 40 Code of Federal Regulations
(CFR) Parts 1500-1508; and the DOE NEPA Implementing Procedures, 10 CFR
Part 1021.
Copies of the draft TWRS EIS have been distributed to Federal,
State, and local officials, Tribal Nations, as well as agencies,
organizations, and individuals who may be interested or affected. The
draft EIS and supporting technical reports also are available for
public review in DOE reading rooms and designated information
repository locations identified in this notice.
Public scoping comments were assessed and considered both
individually and collectively by DOE and Ecology. Some comments
resulted in modifications to the initial scope of the EIS as described
in the Notice of Intent. Scoping comments and DOE and Ecology responses
to those comments can be found in the Implementation Plan for the TWRS
EIS, issued December, 1995 (DOE/RL-94-88). The Implementation Plan is
available by contacting the persons listed in the ADDRESSES section of
this notice or in the DOE reading rooms and information repositories
identified in this notice.
Alternatives Considered
Tank waste alternatives discussed in the EIS are:
No Action--perform minimum activities required for safe
and secure management of Hanford's tank wastes with the current tank
farm configuration;
Long-Term Management--perform minimum activities required
for safe and secure management of Hanford's tank waste, including
upgrades to tank farms with the current single-shell tank farm
configuration and the replacement of the double-shell tanks twice
during a 100-year period;
In Situ Fill and Cap--retrieve and evaporate liquid waste
from the single-shell and double-shell tanks, then fill all tanks with
gravel and cover the tank farms with an earthen surface barrier,
disposing of all tank waste onsite;
In Situ Vitrification--retrieve and evaporate liquid waste
from the single-shell and double-shell tanks, then vitrify all of the
tank waste in place and cover the tank farms with an earthen surface
barrier, disposing of all tank waste onsite;
Ex Situ No Separations--retrieve all tank farm waste
practicable (assumed to be 99 percent), then either vitrify or calcine
the waste and package the treated waste form for onsite storage and
eventual offsite disposal at a high-level waste geologic repository;
Ex Situ Intermediate Separations--retrieve all tank farm
waste (99 percent) and separate the high-level and low-activity waste
streams using sludge washing and ion exchange, then vitrify the waste
streams in separate facilities and package the treated waste forms for
onsite disposal of immobilized low-activity waste and offsite disposal
of the immobilized high-level waste at a geologic repository;
Ex Situ Extensive Separations--retrieve all tank farm
waste (99 percent) and separate into high-level and low-activity waste
streams using sludge wash, ion exchange, caustic leach and acid
dissolution, then vitrify the waste streams in separate facilities and
package the treated waste forms for onsite disposal of the immobilized
low-activity waste and offsite disposal of the immobilized high-level
waste at a geologic repository;
Ex Situ/In Situ Combination--retrieve tank waste (50
percent assumed) based on the risk posed to human health or the
environment, separate the retrieved waste into high- level and low-
activity waste streams using sludge washing and ion exchange, then
vitrify the waste streams in separate facilities, and package the
treated waste forms for onsite disposal of the immobilized low-activity
waste and offsite disposal of the immobilized high-level waste at a
geologic repository, fill all tanks, including those with waste that
had not been retrieved, with gravel, cover the tanks with a barrier,
permanently disposing of the waste in-place. As a subalternative to
this alternative, DOE will examine the Ex Situ treatment of the largest
contributors to long-term risk, while limiting the volume of waste to
be treated; and
Phased Implementation--similar to the Ex Situ Intermediate
Separations alternative whereby Phase 1 consists of construction of two
commercial demonstration-scale facilities that would include one low-
activity waste separation and vitrification demonstration plant and one
low-activity and high-level waste vitrification demonstration plant
which operate for up to 10 years. These facilities could treat up to 30
percent of the tank waste by volume during the 10-year operating
period. In Phase 2, DOE would construct larger capacity separation and
vitrification plants, retrieve the remaining waste, separate
[[Page 16473]]
the waste into low-activity and high-level waste streams, vitrify the
waste in separate facilities, package the waste and dispose of the low-
activity waste onsite in near-surface vaults and the high-level waste
offsite at a geologic repository.
The radioactive cesium and strontium capsules produced from
reclaimed materials in tanks are currently classified as waste by-
product. The capsules may have potential commercial or other beneficial
use. If a beneficial use cannot be found, the capsules would become
subject to management and disposal actions as high-level waste. Cesium
and strontium capsule alternatives analyzed in the EIS are: No Action--
Continue existing operations and maintenance in the Hanford Site Waste
Encapsulation and Storage Facility for 10 years; Onsite Disposal--
overpack the cesium and strontium in canisters and store onsite
indefinitely in a newly constructed dry-well storage facility; Overpack
and Ship--overpack the cesium and strontium into canisters, which would
then be overpacked into larger canisters, and disposed of offsite at a
potential geologic repository; and Vitrify with Tank Waste--remove
capsule contents and vitrify with the high-level tank waste, and
dispose of offsite at a potential geologic repository.
The draft EIS identifies and compares the potential environmental
impacts associated with these alternatives for managing and disposing
of Hanford's radioactive, hazardous and mixed tank waste and
encapsulated cesium and strontium.
Preferred Alternatives
DOE's and Ecology's preferred tank waste alternative is the Phased
Implementation alternative. DOE and Ecology do not yet have a preferred
alternative for the Hanford Site's encapsulated cesium and strontium.
Invitation to Comment
DOE has completed the general distribution of the draft TWRS EIS
and has filed it with the Environmental Protection Agency, which will
publish a Notice of Availability elsewhere in the Federal Register. The
draft TWRS EIS will also be available to the public in the DOE reading
rooms and designated information repository locations identified in
this notice. DOE plans to issue the final TWRS EIS in July 1996 and a
Record of Decision by August 1996.
Persons interested in speaking at the hearings may register at the
hearing and will be called on to speak on a first-come first-served
basis. Written comments will also be accepted at the meetings, and
speakers are encouraged to provide written versions of their oral
comments for the record. Oral and written comments will be considered
equally in preparing the final EIS.
DOE and the Washington State Department of Ecology will also
conduct workshops and meetings in Washington or Oregon on the EIS for
organizations during the public comment period. The workshops and
meetings will provide an opportunity for interested persons and the
public to learn more about the alternatives and analysis presented in
the EIS. The dates of the workshops and meetings have not been
scheduled at this time. Interested persons should call 1-800-321-2008,
to schedule a workshop before May 7, 1996.
