DOE Idaho site reaches 20-year cleanup milestone
IDAHO FALLS, ID- In two decades of Superfund cleanup
work, the U.S. Department of Energy's Idaho site has removed
hundreds of thousands of cubic yards of radioactive and
hazardously contaminated soils, excavated radioactive waste
buried since the 1950s, removed three nuclear reactors and
hundreds of buildings, completely closed three major nuclear
facilities and removed thousands of unexploded ordnance
shells and fragments.
Last month marked the 20-year anniversary of the signing
and implementation of a cleanup agreement between DOE, the
U.S. Environmental Protection Agency and the state of Idaho.
In two decades, the cleanup agreement known as the Federal
Facility Agreement and Consent Order has never been revised
and DOE's cleanup contractors have met all but four of the
literally hundreds of milestones outlined in the document.
The missed milestones were subsequently renegotiated.
"We've made great progress in cleaning up the Idaho site,
further protecting the Snake River Plain Aquifer," said
James Cooper, deputy manager for DOE Idaho's Cleanup
Project. "The visible progress in just the last five years
is staggering."
American Recovery and Reinvestment Act funds,
appropriated in 2009, helped the Idaho Cleanup Project
accelerate many legacy projects by several years. At the
beginning of the Site's cleanup mission, it was believed
that cleanup of hundreds of radioactive, hazardous and
debris sites would take until 2035 or later to complete. DOE
accelerated the cleanup mission of the Site, with the bulk
of work predicted for completion within the next several
years, saving taxpayers billions of dollars.
The Idaho National Laboratory was added to the EPA's
Superfund National Priorities List in 1989 due to the
890-square-mile Site's potential impact on the underlying
Snake River Plain Aquifer, a Lake Erie-sized body of water
that runs underground from Ashton to Thousand Springs,
Idaho. Prior to becoming a Superfund site, INL discharged
contamination into unlined ponds, had leaks from its
facilities and underground storage tank piping and injected
water directly into the aquifer. Although INL implemented
common industrial disposal techniques at the time, those
activities threatened the aquifer.
Of most concern was the potential impact to the aquifer
beneath the Radioactive Waste Management Complex, where
barrels and boxes of radioactive and hazardous waste were
buried from 1952 until 1970 within a 97-acre area known as
the Subsurface Disposal Area. Since 1996, solvent vapors
that were released from the barrels and boxes as they
degraded over time have been removed by a series of vacuum
extraction units that suck the vapors from the ground and
destroy the solvents by heating up the material in the same
manner as an automobile catalytic converter. Crews have been
digging up the waste since January 2005.
Cleanup at the Subsurface Disposal Area also continues.
The project is anticipated to be completed ahead of
schedule, with a soil cap placed over the entire landfill.
The cap will prevent any remaining pollutants from migrating
deeper in to the subsurface or the aquifer.
"We've continually picked up the pace of waste exhumation
since we were awarded the cleanup contract in 2005," said
CH2M-WG Idaho, LLC., president and CEO Tom Dieter. "Being
able to begin cap construction several years ahead of
schedule will save taxpayers hundreds of millions of
dollars."
A cap will also be installed over the Tank Farm located
at the Idaho Nuclear Technology and Engineering Center,
formerly known as the Chem Plant. About 900,000 gallons of
radioactive and hazardous liquid waste remains in three
300,000-gallon tanks within the Tank Farm. The tanks will be
emptied by December 2012, and filled with a cement grout.
"Many of these cleanup projects are undertaken with
protection of the aquifer being the top priority," said
Cooper. "All contaminated sites that have impacted the
aquifer have either been addressed or are currently being
addressed. That's encouraging news."
CH2M-WG Idaho, LLC, (CWI) is a partnership comprised of
CH2MHill and the URS Corporation that directs the Idaho
Cleanup Project at the Department of Energy's Idaho Site
located 45 miles west of Idaho Falls. The 7-year, $2.9
billion project, funded through the U.S. Department of
Energy's Office of Environmental Management, focuses on
early risk reduction and protection of the Snake River Plain
Aquifer.
