Decontamination & Decommissioning of Radiological Facilities
New World Environmental, Inc. (NWE)
was contracted by the Navajo Nation
Environmental Protection Agency (NNEPA) to perform remediation, removal, packaging, and transportation of waste, Final Status Survey (FSS) of land areas, and reclamation of impacted areas at the NNEPA Highway 160 Project Site
(Site), located near Tuba City, AZ.
Remediation activities included the following tasks:
Removal action of radioactive and other contaminated soil, soil-like material, and other
Packaging of Class 7 (Radioactive) waste for shipment.
Shipment of Class 7 and non-classified Radioactive waste to the Grand Junction.
Disposal Cell (GJDC).
Characterization of the excavation for other waste constituents, such as Resource
Conservation and Recovery Act (RCRA) metals.
Final Status Surveys of the excavated land areas to ensure compliance with U.S. EPA surface
and subsurface criteria for Uranium Mill Tailings Radiation Control Act (UMTRCA) limits.
Reclamation actions in accordance with the NNEPA Site Reclamation Plan.
On-site Radiological Laboratory
In order to meet the Highway 160 Project Data Quality Objectives (DQOs), NWE deployed to the site a mobile laboratory in order to provide both comprehensive and scientifically defensible data that supported meeting the release criteria. The project required collection and analysis of soil and other materials in addition to radiological surveys or scanning.
The Project objectives that led to the decision to deploy the onsite laboratory were:
Excavate "low-level" residual radioactive material mixed with soil at the Highway 160 Project site that exceeded the 2 pCi/g limit as stated in the contract with the Navajo Nation.
Conduct surveying and sampling activities before, during and after remediation activities to determine that mitigation efforts had been met.
Ensure that the operations did not spread, or did not facilitate the spread, of contamination.
Protect the health of any and all personnel at the site, the general public and related
Monitor for airborne radioactive materials.
Prepare excavated materials for transportation in accordance with U.S.
Department of Transportation regulations and the DOE GJDS requirements as set in the
Coordinate project deadlines and objectives with all agencies involved: Department of Energy, Department of Energy Contractors, Waste Facility Management and our Client, NNEPA
Direct subcontractors' tasks and manage critical task deadlines
