With the publication of its report on alternatives to incineration,
a blue ribbon panel outlines a rational approach for DOE to follow
in structuring a comprehensive research, development, demonstration,
and deployment (RDD&D) program to move forward the technologies
the panel identifies as promising.
The panel was born out of an out-of-court settlement between DOE and
environmental activist groups who sued the department in September
1999 over the departments plan to build an incinerator at the
Idaho National Engineering and Environmental Laboratory (INEEL)
for treating radioactive mixed waste. The groups bringing the suit
were concerned about the potential for release of plutonium. Under
the terms of the settlement, DOE agreed to reconsider its plan to
build a new incinerator and create an independent panel to investigate
emerging technological alternatives to incineration. The panel issued
its report in December 2000.
The Blue Ribbon Panel on Emerging Technological Alternatives to Incineration,
which was established as a task force of the Secretary
of Energy Advisory Board, was charged to evaluate technologies
to treat low-level, alpha low-level, and transuranic (TRU) wastes
containing polychlorinated biphenyls and hazardous constituents, including
the up to 14,000 cubic meters of such waste that DOE had planned to
incinerate at the Advanced Mixed Waste Treatment Facility at INEEL.
The panel was also asked to evaluate whether these technologies could
be implemented in a manner timely enough to enable DOE to comply with
a consent order requiring it to remove from Idaho 65,000 cubic meters
of INEEL waste by the end of 2018.
The nine-member panel was composed of five members appointed by the
Secretary of Energy, one member appointed by each of the governors
of Idaho and Wyoming, and two members appointed by public interest
groups. During five formal meetings over six months, the panel was
briefed on applicable regulations, inventory, and characteristics
of the mixed transuranic waste stored at INEEL, and DOEs research
and development plans on alternatives to incineration. A five-member
subpanel, reporting to the full panel, also reviewed information on
technology options submitted by firms and other parties that responded
to a panel-issued Request for Information (RFI). Also, as part of
its deliberations, the panel considered comments it heard from the
public, who were invited to attend each of the five formal meetings.
The panel adopted seven criteria in evaluating viable technology
options. These criteria were specified in the August 2000 RFI:
Environmental, Safety, and Health
Risk Considerations
Stakeholder and Regulatory Interests
Functional and Technical Performance
Operational Reliability
Pre- and Post-Treatment Requirements
Economic Viability
Maturity
The panel also identified five general categories of technology options:
Thermal treatment without
incineration
Aqueous-based chemical oxidation
Dehalogenation
Separation (soil washing, solvent extraction, and thermal desorption)
Biological treatment
Focusing on technology criteria and categories and considering the information
on technology options generated by the RFI and from other sources, the
panel identified the following alternatives to incineration as the most
promising in terms of their maturity; robustness; secondary wastes;
and risk to workers, the public, and the environment. Three of the four
most promising technologies fall into the thermal treatment
without incineration category:
Steam reforming
Thermal/vacuum desorption
DC arc melter
Plasma torch
The panel also identified a number of technologies that show promise
but have unresolved technical issues that put them on a longer path
to deployment:
Mediated electrochemical oxidation
Microwave decomposition
Supercritical water oxidation
Solvated electron dehalogenation
Recognizing that none of the technologies it reviewed are ready now
to treat TRU waste, the panel urged DOE to commit to securing funding
for a comprehensive RDD&D program to move forward the technologies
the panel identifies as promising. A system approach will
allow viable technologies to be combined into workable systems for treating
a wider range of mixed waste. The technologies identified as most mature
have a good chance of being ready, with adequate DOE funding, in time
to meet DOEs deadline with the state of Idaho.
While the panel was supportive of DOEs plans to conduct comparative
and integrated testing of candidate technologies, it argued that such
a testing program must use the actual materials to be treated. The
panel also stated that a comprehensive testing program would require
funding levels much higher than DOE has budgeted. The panel supported
a budget that would provide approximately $91 million to the
Transuranic and Mixed Waste Focus Area over the four fiscal years
beginning in 2001. The panel questioned whether currently budgeted
funding levels would be adequate to ensure that technologies will
be ready to meet DOEs legally enforceable deadlines.
The panel also urged that DOE commit to deploying the technologies
that prove themselves during proof testing and not abdicate to commercial
interests its responsibility for solving DOEs mixed waste problems.
In conjunction with an extensive testing program for near-term problems,
the panel strongly supported increased and continuing basic scientific
and development work over the longer term to address problems for
which there are no currently acceptable solutions. Finally, the panel
recommended that DOE broaden stakeholder outreach beyond the departments
site-based citizen advisory boards by making sufficient, specific
budgetary provision for technical assistance to citizen committees.
DOE should ensure that these citizen committees have ongoing involvement
in the RDD&D process.
The panel called for a 2001 conference to begin a national dialogue
on alternative technologies to incineration. The panel recommended
that a broad base of participants be invited, including state, local,
and tribal governments and national environmental, labor, and other
groups having interests, commitment, and expertise on the issues.
DOE began the planning process for this national stakeholder forum
by convening a special session during a recent DOE-sponsored conferenceDeveloping
Strategies to Accelerate Federal Agency Environmental Cleanupheld
near Salt Lake City in April 2001. Approximately 40 stakeholders,
DOE staff, and other interested parties discussed an effective approach
for achieving the goals of the national forum recommended by the panel.
Although the panel disbanded with the publication of its report, the
Environmental Management Advisory
Board, recognizing the significance of developing publicly acceptable
alternatives to incineration, has established a new EMAB committee.
The Alternative Technologies to Incineration Committee will facilitate
stakeholder comment and communications on issues related to emerging
alternative technologies to incineration for the treatment of mixed
TRU and low-level wastes. The first meeting of the ATIC was June 13,
2001.
