Our Recent Projects

Fort Ord

KEMRON, as the prime contractor, completed a five-and-a-half-year task order for CERCLA MEC (Munitions and Explosives of Concern) and HTRW (Hazardous, Toxic, and Radioactive Waste) remediation at multiple sites at the former Fort Ord, a 28,000-acre BRAC facility. KEMRON’s work spanned various services, including asbestos and lead-based paint surveys, demolishing 33 base structures, operating the construction/demolition debris section of the OU 2 Landfill, performing erosion control projects, building access roads, conducting biological monitoring, managing MEC clearance in 14 vernal ponds, maintaining administrative records, managing complex databases and GIS interfaces, and providing 770 days of anomaly avoidance/construction support.

Vegetation Clearing: KEMRON conducted both mechanical and manual cutting over 641 acres for planned prescribed burns. Manual cutting included significant brush clearing and tree limbing up to 8 feet above ground. All manually-cut vegetation was collected and stockpiled for chipping, supporting various erosion control projects.

Surface MEC Remediation: Following vegetation clearance, KEMRON completed surface MEC removal on 1,525 acres. In BLM Area B, KEMRON provided security during clearance operations as public access had been previously allowed in these areas. No QC failures were experienced during surface MEC removal.

Digital Geophysical Mapping (DGM): KEMRON completed DGM on 1,830 acres using a towed array comprised of three EM61-MK2 sensors. In areas of special biological concern, such as vernal ponds, a single EM61-MK2 sensor in person-portable mode was used.

Advanced Geophysical Classification (AGC): KEMRON championed the use of AGC, successfully completing eight AGC projects, making Fort Ord one of the leading sites for AGC application. The estimated total cost savings using AGC at Fort Ord was just over $1 million. AGC data was collected in both dynamic and cued mode, utilizing four different AGC sensors. The reduction from total anomalies to targets of interest ranged from 55% to 91%, with KEMRON removing 1,460 MEC or MEC-like items during the eight AGC studies.

Subsurface MEC Clearance: KEMRON performed subsurface MEC clearance on 162 acres along trails, road realignments, containment lines for prescribed burns, and to evaluate targets for AGC. Boundary markers were installed to delineate areas with subsurface MEC clearance along roads and trails.

MPPEH Management: KEMRON removed/detonated 7,173 MPPEH (Material Potentially Presenting an Explosive Hazard) items through numerous demolition operations using both consolidated shots and blow-in-place (BIP). KEMRON managed 218 tons of MD (Munitions Debris) and 218 tons of range-related debris for recycling or disposal at the OU2 landfill. MD was inspected for radium dials according to the Radiation Safety Plan due to the removal of armored personnel carriers with radium dials under a previous task order.

Prescribed Burns: In collaboration with the USACE Sacramento District and the Presidio of Monterey Fire Department, KEMRON successfully conducted prescribed burns in Units B and C in BLM Area B. The purpose was to facilitate future MEC investigation and remediation by removing dense chaparral vegetation, as outlined in the Habitat Management Plan. There were 241 total burn acres, with the remaining area serving as fuel breaks. KEMRON prepared the fuel breaks via mastication and surface MEC removal to ensure the safety of ground personnel during the burn and post-burn monitoring. This complex operation involved over 100 personnel and was conducted without any safety incidents, earning commendations from USACE and POMFPD.

Basewide Range Assessment: KEMRON conducted extensive incremental soil sampling, analyzing 231 samples for lead and explosives in eight units of the former Impact Area. One location in Unit 33 contained lead above the cleanup level, prompting the collection and analysis of 36 additional step-out samples to refine the extent of contamination.

Site Inspection: KEMRON conducted field reconnaissance in three units in the eastern portion of the Impact Area with steep terrain, using LiDAR and historical information to evaluate potential areas of munitions usage.

Technical Documents: KEMRON prepared 103 technical documents reviewed by EPA Region 9 and the California Department of Toxic Substances Control (DTSC). These documents included the ROD for BLM Area B, RI/FS Report, RD/RA Work Plans, and Explosives Safety Submissions. Additionally, KEMRON analyzed and reported data from surface MEC removal and DGM in 25 Technical Memoranda. RA Completion Reports were prepared to document all remedial actions. KEMRON also prepared the fourth Five-Year Review in accordance with CERCLA.

Throughout this large and complex MEC removal project, KEMRON adapted its approach to maintain the schedule while ensuring high-quality performance. This included completing required vegetation clearance and subsurface MEC clearance to support planned prescribed burns each year before the burn season and adding additional UXO technicians as needed to meet the BRAC schedule. The project extended six months to cover an additional burn season.
