SpecPro supports USACE at Yuma Proving Ground (YPG) with environmental remediation services to amend and expand previous investigations under the Resource Conservation and Recovery Act (RCRA) for the Muggins Mountain Open Burn/Open Detonation (OB/OD) Range
The primary aim is to ensure proper delineation of the CCYPG-35a boundary and support the facility’s closure under Arizona Department of Environmental Quality (ADEQ) oversight.
Relevant Tasks:
Boundary Investigation & Expansion Study
- Assess approximately 309 additional acres beyond the existing 392-acre OB/OD Range boundary (including MRS areas CCYPG-35a, b, and c).
- Use digital geophysics and structured sampling to detect Munitions and Explosives of Concern (MEC), Improved Conventional Munitions (ICM), and Material Potentially Presenting an Explosive Hazard (MPPEH).
- Determine whether munitions originate from historic OB/OD operations or test activities.
UXO and Geophysical Support
- Provide UXO-qualified personnel (UXOQP) for MEC surface clearance and safety oversight.
- Conduct Digital Geophysical Mapping (DGM) and anomaly avoidance techniques.
- Excavate and destroy MEC as required, including up to 100 dual-primed shots.
Groundwater Monitoring
- Complete construction and development of two monitoring wells (MW-2 and MW-3) up to 450 feet deep.
- Perform semi-annual groundwater sampling for munitions constituents, metals, and perchlorate.
- Analyze data using EPA methods and submit validated electronic deliverables.
Document Preparation and Reporting
- Amend and update key documents including:
- Uniform Federal Policy Quality Assurance Project Plan (UFP-QAPP)
- Explosives Siting Plan (ESP)
- Site Safety and Health Plan (SSHP)
- Supplemental RCRA Facility Investigation (SRFI) report
- Corrective Measures Study (CMS) addendum
- Post-Closure Care Plan (PCCP)
- Prepare RCRA Part B Class I Permit Modification Requests (PMRs) for boundary changes, CMS updates, and PCCP submission to ADEQ.
- Incorporate findings into a comprehensive SRFI addendum and CMS report.
- Maintain a full Administrative Record of all documents and data.
