E.P.A. begins 3 Navajo uranium mine cleanups in September / Work on the plans expected to total over $7 million

SAN FRANCISCO - This month, the E.P.A. is beginning 3 uranium mine clean up actions on the Navajo Nation. The work, expected to cost $7.15 million, is part of the EPA's 5 year project to address uranium contamination on the Navajo Nation and is being done in partnership with the Navajo Nation's E.P.A.. Backing for all 3 actions is from responsible parties, rather than the Superfund trust fund. The 3 cleanups will take place in Cove, Arizona; Casamero Lake, New Mexico; and near Church Rock, New Mexico. The E.P.A. expects to complete the cleanups by November.

The 1st cleanup in the Cove area is expected to cost $1.5 million and take 4 to 6 weeks. Uranium mining in Cove Chapter, which lasted from the 1940s to the 1980s, included 2 transfer stations where uranium-bearing ore from the mines was stockpiled before trucks took the ore to the Shiprock Mill for processing. The transfer stations still contain some leftover uranium-tainted ore. Because this residual ore is hazardous, the public should avoid these areas until the cleanup is complete. E.P.A. will remove the contaminated soil at Cove from one transfer station to another, where it will be sealed and stabilized. The area will be fenced and warning signs will be posted until a permanent disposal location can be selected. During the cleanup process, E.P.A. will conduct air quality monitoring to ensure that residents in the immediate area -- including the students at Cove Day School -- are protected from any dust from the excavation.

Near Casamero Lake, New Mex., E.P.A. will clean up contaminated soil left by the Section 32 Mine. That cleanup will cost an estimated $1.65 million and will include consolidating scattered contaminated soils on the main mine waste pile. Once that process is completed, the contaminated soils will be secured using a soil sealant, or temporary clean soil cover. The location will also be fenced until a final disposal decision is reached.

North of Church Rock, E.P.A. will oversee work by General Electric/United Nuclear Corporation and Rio Algom Mining to clean up soils and a road located near the Northeast Church Rock Mine, the biggest underground uranium mine in the U.S, and the Quivira mine which is located approximately 1/4 mile to the northeast. The UNC mine was operated from 1967 to 1984 and produced approximately 9.8 million pounds of uranium. The Quivira Mine was operated between 1976 and 1985 and produced 3.1 million pounds of uranium. This fall's $4 million dollar work at the 2 areas near the Northeast Church Rock and Quivira mines precedes a larger $44 million cleanup of the Northeast Church Rock Mine expected to begin in 2016, contingent upon federal agency approvals.
