Six core capabilities. One contract.
End-to-end federal remediation from initial site characterization through final regulatory closure — no subcontractor coordination risk.
Capability 01
Mine Reclamation
Clawson-EnergySolutions JV has executed full-surface reclamation across more than 83 legacy uranium and coal mine sites on Navajo Nation lands. That depth covers every phase: waste pile delineation, excavation, characterization, transport, cell closure, recontouring, and final revegetation.
Our field systems are purpose-built for the region's logistics constraints. Sites with no paved access, no grid utilities, seasonal water scarcity, and strict cultural resource protection requirements are our baseline — not exceptions we work around.
Key Services
- Waste pile delineation and volumetric estimation
- Radiological screening and media characterization
- Waste cell excavation and disposal coordination
- Chain-of-custody manifest management
- Site recontouring and drainage design
- Native seed mix revegetation and establishment
- Cultural resource identification and avoidance
- Remote site logistics and crew welfare systems

Capability 02
Environmental Remediation & Radiological Cleanup
EnergySolutions' NRC broad-scope materials license (No. 39-35044-01) authorizes the JV to handle the full radiological remediation lifecycle — from initial field survey and dose-rate mapping through excavation under Radiation Work Permits, offsite transport, and disposal at a licensed facility. No subcontract for the licensed work; no split in the chain of custody.
The JV's Health Physics staff execute MARSSIM-compliant Final Status Surveys and provide the regulatory documentation package — dose assessment, release comparison, and survey data — required for NRC or EPA concurrence on site closure.
Key Services
- Radiological field surveys and dose-rate mapping
- Soil, water, and air sampling and lab analysis
- MARSSIM Final Status Survey execution
- Excavation under Radiation Work Permits
- Radiological control technician support
- Offsite transport with full chain-of-custody
- Disposal at NRC- and EPA-permitted facilities
- Regulatory closure documentation package
Capability 03
Hazardous Waste Management
Legacy mine sites typically contain mixed waste streams: radiologically impacted material, RCRA-listed and characteristic hazardous waste, and inert debris managed under separate regulatory frameworks. The JV handles all three — with licensed personnel, permitted transport arrangements, and approved disposal facilities for each stream — under a single contract.
Cradle-to-grave management begins at the point of generation: waste characterization sampling, profile approval from the receiving facility, DOT-compliant containerization and labeling, uniform hazardous waste manifest preparation, and licensed transporter coordination through final disposal documentation.
Key Services
- Waste characterization sampling and laboratory analysis
- Waste profile development and receiving facility approval
- DOT-compliant containerization, labeling, and placarding
- Uniform Hazardous Waste Manifest preparation and tracking
- Licensed transporter coordination and scheduling
- LDR land disposal restriction documentation
- Disposal at RCRA-permitted treatment and storage facilities
- Exception reports and regulatory agency notification
Capability 04
Decommissioning & D&D
Decontamination and decommissioning of radiologically impacted structures, equipment, and site infrastructure requires integrated Health Physics oversight from the first characterization survey through the NRC release survey. The JV executes D&D work under NRC materials license with in-house Radiation Protection Managers — maintaining continuous regulatory chain of custody across the full scope.
Work scope ranges from decontamination of process equipment and piping to full structural demolition of radiologically impacted buildings, with rubble survey, classification, and packaging for licensed disposal or release. Final Status Survey results are compiled into a regulatory closure package submitted to NRC or state agreement state authorities.
Key Services
- Baseline radiological characterization and dose assessment
- Surface decontamination of equipment and structures
- Demolition under Radiation Work Permits
- Rubble survey, classification, and waste packaging
- Radiation Protection Manager oversight throughout scope
- MARSSIM Final Status Survey and data reporting
- NRC license termination documentation support
- Dose-to-public release comparison and concurrence package
Capability 05
Construction Engineering
Clawson Excavating has moved earth on remote mine sites across Navajo Nation lands for more than two decades — building access roads into project areas with no existing infrastructure, installing drainage structures to prevent erosion and downslope contamination, and performing the precision recontouring work that defines whether a reclaimed site passes regulatory review.
That field depth translates to a construction operation that does not slow down when conditions get difficult: seasonal road closures, limited material sources, strict stormwater permit requirements, and cultural resource monitoring at every dig. Our equipment fleet and crew welfare systems are maintained for sustained remote deployment, not day-trips.
Key Services
- Access road design and construction
- Culvert and drainage structure installation
- Site grading and precision recontouring
- Soil borrow identification and fill management
- Stormwater pollution prevention (SWPPP) compliance
- Erosion and sediment control installation
- Remote-site logistics and crew deployment
- Cultural resource monitoring during excavation
Capability 06
Regulatory Compliance
Federal remediation programs operate under layered regulatory authority: NRC materials licenses, EPA RCRA corrective action orders, state environmental permits, NEPA environmental reviews, and tribal consultation requirements. The JV's regulatory team manages all of them — coordinating agency correspondence, preparing permit applications and license amendments, and maintaining the compliance documentation record that supports site closure approval.
Experience with both NRC and EPA frameworks — and the tribal consultation processes specific to Navajo Nation work — means the JV does not need to learn the regulatory landscape on the job. We have existing working relationships with the agencies and tribal offices that govern Four Corners remediation programs.
Key Services
- NEPA environmental assessment and EA/EIS support
- EPA and state RCRA permit applications and renewals
- NRC license applications, amendments, and decommissioning plans
- Biological resource and jurisdictional wetlands surveys
- Cultural resource identification, monitoring, and avoidance plans
- Tribal consultation coordination and documentation
- Compliance monitoring reports and inspection preparation
- Site closure and license termination documentation packages
