Superfund record of decision (EPA Region 10): USDOE Idaho National Engineering Laboratory, operable units 5-05, 6-01, and 10 no action sites, Idaho Falls, ID, December 1, 1995
The Idaho National Engineering Laboratory (INEL) has been subdivided into 10 waste area groups for investigation pursuant to the Federal Facility Agreement and Consent Order between the DOE, EPA and IDHW. The major components of the selected remedy for both sites are: Containment by capping with an engineered barrier constructed primarily of native materials; For BORAX-I implementation will include consolidation of surrounding contaminated surface soils for containment under the engineered cover; Contouring and grading of surrounding terrain to direct surface water runoff away from the caps; Periodic above-ground radiological surveys following completion of the caps to assess the effectiveness of the remedial action; Periodic inspection and maintenance following completion of the caps to ensure cap integrity and surface drainage away from the barriers; Access restrictions consisting of fences, posted signs, and permanent markers; Restrictions limiting land use to industrial applications for at least 100 years following completion of the caps; and Review of the remedy no less often than every five years until determined by the regulatory agencies to be unnecessary.
