Camp Navajo MEC Surface Clearance
ERRG recently completed a MEC surface clearance at Camp Navajo, on approximately 459 acres of former Open Burn/Open Detonation (OB/OD) area located near Bellemont, Arizona. The project included transportation of MEC items to an explosive storage magazine, identification of munitions debris and the performance of blow in place (BIP) procedures on ordnance items that were deemed unsafe to move. ERRG continuously exceeded the required production rate of clearing thirty five-200-foot by 200-foot grids per week, averaging 10.3 grids per day (51.5 per week). ERRG completed the entire project in ten (10) weeks with no failures.
URS/PG&E Soil and Groundwater Remediation at Hunters Point Power Plant
ERRG, as a team subcontractor to URS Corporation, will assist Pacific Gas and Electric Company in the remediation of soil and groundwater at former Hunters Point Power Plant. ERRG will excavate contaminated soil from ‘hot spots’ identified in the Remedial Action Plan and load the soil into trucks for disposal at approved facilities. Residual petroleum hydrocarbons in groundwater affecting two areas will be remediated in-situ by mixing a chemical oxidant with the petroleum hydrocarbons. After the hot spots are excavated and backfilled and petroleum hydrocarbons are oxidized, ERRG will grade and pave the surfaces to limit contact with historic fills.
Presidio Trust Building 208 Remedial Unit
ERRG was recently awarded a new project from the Presidio Trust. In addition to site prep activities, including work plans, storm water controls, and fencing, ERRG will decommission a storm utility drain, demolish 480 square feet of pavement at Building 208, and demolish 330 square feet of sidewalk. Once the decommissioning and demolition activities are completed, ERRG will recycle the concrete, brick and asphalt. Site work will also include the excavation, transportation, and disposal on 6,000 tons of Non-Hazardous, Non-RCRA Hazardous, and RCRA Hazardous waste. Final site activities will include backfilling, placement of a geotextile fabric and pavement replacement.
