& Projects - Historic LLRW
Northern Transportation Route
the early 1990s, the LLRWMO identified a number of uranium ore-contaminated
sites along the Northern Transportation Route (NTR), a 2,200-km marine and
portage route used in the past to transport uranium ore and concentrates
from the Northwest Territories (NT) to the railway in northern Alberta.
NTR extends from the Port Radium Mine site on Great Bear Lake, via a system
of lakes and rivers (including Great Bear and Great Slave Lakes, and the
Great Bear, Mackenzie, Slave and Athabasca Rivers) south to Fort McMurray,
subsequent years the LLRWMO has completed radiation surveys at potential
transfer points along the NTR, removed and consolidated contaminated soil at
temporary storage sites along the route, from residential properties in Fort
Smith and Tulita, NT and from nine different remediated sites in Fort
McMurray, Alberta. The contaminated material was then placed in engineered
storage mounds where annual inspections are conducted by the LLRWMO as
necessary to ensure a safe environment for local residents.
LLRWMO continues to have an active interest in the remaining NTR sites to
ensure that the contaminated soils do not impact the public or the
LLRWMO achieved a major milestone in FY 2008-09 with the transfer of bagged
uranium-ore contaminated soil from a temporary interim storage stockpile in
Tulita, NT to a disposal site in the U.S.. The successful conclusion of the Tulita
Disposal Project fulfills a long-standing commitment by the Government of
Canada to remove historic LLRW from this community.
at Tulita begins, between
1993 and 2001, when pockets of uranium ore contaminated soils found in Tulita
were consolidated at a temporary storage location in the area of the old
landfill site near the community's airport.
2006, the LLRWMO packaged uranium impacted soil into 755 bulk bags in
anticipation of the transfer of the contaminated material to an acceptable
location for the long term.
2008, between September and November, 755 bulk bags containing an estimated
867 cubic metres of uranium-impacted soil was removed from Tulita and
transported by road and barge to a marine terminal in Hay River, NT. From
there, it was transported by rail to a licensed hazardous and radioactive
waste treatment and disposal facility in Idaho. The final shipment of the
waste was received at the U.S. facility in January 2009.
annual monitoring of LLRWMO-managed sites along the NTR continues with
monitoring and inspection of the
Fort Smith Landfill cell, the Fort Fitzgerald area and the Fort McMurray waste storage
facility ensuring that these
inventories have no impact on the public and the surrounding environment.
LLRWMO is currently participating with NRCan in discussions with local
communities on the final remediation of the Sawmill Bay (NT) site (a former
Distant Early Warning [DEW] Line site) and the Fort Fitzgerald (AB)
community. Both areas are impacted as a result of the transportation of
uranium ores to refinery operations in Port Hope (ON) between the 1930s and
