The Department of Energy is adding another type of radioactive waste to those that won't be sent to Hanford until the vitrification plant is fully operational.
Tuesday, DOE prepared a statement saying that even though its agreement with the states of Washington and Oregon did not cover greater-than-class-C low level radioactive waste, "this waste will not be imported to Hanford for the duration of the moratorium that defers the importation of waste to Hanford."
Greater-than-class-C low, or GTCC, waste is more radioactive than the waste Hanford now is burying in its landfill for radioactive waste, the Environmental Restoration Disposal Facility.
As part of a proposed settlement with the states over a lawsuit brought against DOE, DOE had agreed to recommend in a draft environmental study not to import certain kinds of waste to Hanford until the vit plant is operating to treat high level radioactive tank waste. That's expected to be about 2022. Federal law requires the environmental study before a final decision on the moratorium is made.
The proposed moratorium originally requested by the state of Washington covered only those wastes that DOE had already made a decision to send to Hanford. They included low-level radioactive waste, some mixed with hazardous chemicals, that could be buried in a Hanford landfill for low-level waste. They also included transuranic waste, typically waste contaminated with plutonium, that DOE had planned to send to Hanford for storage.
It did not cover GTCC radioactive waste because DOE has not made a decision yet on where it will be sent for disposal, according to the state of Washington. A separate environmental study is being done on that, which considers Hanford among several other sites.
The waste includes both waste from commercial operations, such as decommissioning nuclear power plants and sterilizing medical equipment, and some DOE waste from nonweapons work that is contaminated with manmade isotopes heavier than uranium.
Why the proposed settlement agreement did not include a moratorium on importing GTCC waste was an issue at the first public hearing on the settlement agreement Monday night in Hood River. Tuesday night a second public hearing was planned in Portland and a message on a Hanford-themed internet board urged people to attend what it called a hearing on GTCC waste.
DOE emphasized the meetings have nothing to do with GTCC waste because it is not part of the proposed agreement with the states.
A third meeting will be Thursdayat the Hampton Inn in Richland to discuss the settlement agreement. The agreement would extend deadlines for emptying radioactive waste from leak-prone underground tanks and for treating the waste to dates that DOE and the state of Washington believe are realistic. The meeting will start with an open house at 6 p.m. followed by the formal meeting at 7 p.m.

Feds make decision about Hanford contaminated soil
RICHLAND — The federal government has made the first decision on how to clean up contaminated soil in the heart of Hanford, settling on a combination of methods planned to protect the environment.
The soil, contaminated with plutonium, is within the central 10 square miles of Hanford that will be permanently used for radioactive and hazardous waste disposal. Land use plans call for no one to ever live there and the area will be cleaned up only to industrial standards.
"This decision balances public sentiment for digging deeper with a science-based cleanup action that will protect human health and the environment," said Matt McCormick, manager of the Department of Energy Hanford Richland Operations Office, in a statement. "This decision was based on the anticipated future use of this area of the Hanford Site."
Some vit plant legal deadlines at risk, DOE reports
Some vit plant legal deadlines at risk, DOE reports
The Hanford vitrification plant is in jeopardy of not meeting deadlines recently agreed to in a court-enforced consent decree, a DOE official said Monday.
The announcement by David Huizenga, Department of Energy acting assistant secretary for environmental management, came with the release of a new Construction Project Review report that discusses likely increases to the
$12.2 billion cost of the project. The plant is being built to turn radioactive waste left from weapons production of plutonium into a stable glass form for disposal.
"With the continuation of unresolved technical issues, identification of new risks and realization of existing risks exceeding opportunities, successful completion of the project within the approved project cost of $12.26 billion is a formidable challenge," the report stated.
New cost for Hanford cleanup projected at $112 billion
New cost for Hanford cleanup projected at $112 billion
The new price tag for completing the remainder of Hanford nuclear reservation cleanup, plus some post-cleanup oversight, is $112 billion.
That is down $3 billion from last year, according to projections in the annual Hanford Lifecycle Scope, Schedule and Cost Report.
The drop primarily is because of work accomplished last year using Department of Energy annual budget money and the final year's spending of Hanford's federal economic stimulus money.
Study to look at putting natural gas pipeline under Columbia River
Study to look at putting natural gas pipeline under Columbia River
The Department of Energy is proceeding with an environmental study of building a natural gas pipeline that would travel under the Columbia River to the center of the Hanford nuclear reservation.
Cascade Natural Gas Corp. has been awarded a task order worth up to $5 million to provide technical expertise and other support to DOE to prepare the legally required study, called an environmental impact statement. Cascade also would potentially provide the natural gas as the licensed supplier in the Hanford area.
The project could help meet DOE goals of reducing fuel costs, greenhouse gas emissions and dependence on foreign fuel sources, according to a notice in the Federal Register on Monday.
Hanford regulators will postpone some cleanup deadlines
Hanford regulators will postpone some cleanup deadlines
Hanford regulators have agreed to let some interim environmental cleanup deadlines slide at the nuclear reservation to focus on the highest priority work, given the realities of the federal budget.
The changes are expected to allow work to continue to demolish the Plutonium Finishing Plant, which the Department of Energy heard during public comments should be a priority.
The new plan also retains the focus on completing cleanup along the Columbia River by 2015 and cleaning up contaminated ground water beneath Hanford.
