FE Warren Air Force Base, WY
RORE provided MMRP site investigation and Removal Action and RCRA removal actions on three separate munitions response areas (MRA) on over 700 acres at FEW AFB. This contract included a comprehensive site evaluation, 100% surface clearance, Digital Geophysical Mapping, Geophysical Analysis, anomaly investigation, MEC Disposal, MMPEH processing, and sampling and analysis of munitions constituents. RORE prepared and submitted a comprehensive report and provided recommendations as to whether further munitions response actions were required. RORE simultaneously managed the three MRAs; Hunnicutt Property (off-site), North of Housing, and the Base Lakes. RORE’s execution was sequenced to allow sufficient time for field work, data analysis, and QC concurrence before efficiently moving forward with the next phase of field work in each MRA. This approach allowed RORE to complete site activities 6 months ahead of schedule.
Moffett Field, CA
RORE prepared a Focused Feasibility Study, Proposed Plan, Record of Decision and Land Use Control Remedial Design for Installation Restoration Site 29 (Hangar 1) in accordance with the National Contingency Plan (NCP), CERCLA, U.S. Environmental Protection Agency (EPA) guidance, and Navy policy. These reports are being used to develop and document site management post-Removal Action activities at Hangar 1 and outline the need for no further cleanup action and the long-term management requirements at Hangar 1. Under this Task Order RORE is also performing community relations activities including mailing proposed plan to community members, publishing announcement in major local newspapers, and supporting Restoration Advisory Board (RAB) meetings.
Moffett Field, CA
RORE executed a Site Characterization and Soil Removal to investigate and remediate detected concentrations of polychlorinated biphenyls (PCBs) and petroleum hydrocarbons in soil at the site. The field investigation consisted of the of delineating the areal and vertical extent of PCB-contaminated soils using direct-push Geoprobe drill rig to collect soil and groundwater samples. RORE provided a recommendation report to Regional Water Quality Control Board (RWQCB) delineating impacted soil to be removed. Upon concurrence from the RWQCB, RORE excavated the impacted soil, and applied oxygen releasing compound (ORC) to the excavation bottom in order to expedite the natural attenuation of contaminants. Three groundwater monitoring wells were installed RORE performed four quarters of monitoring confirming the ORC’s effectiveness and complete removal of contaminants.
Naval Air Station North Island, San Diego, CA
RORE performed a Site Characterization and Technology Assessment for the NASNI Fuel Farm LNAPL groundwater plume to fill data gaps and validate low risk closure. RORE used Cone Penetrometer Testing/Rapid Optical Screening Tool (CPT/ROST) to provide in-situ contaminant concentrations. LNAPL recharge data and thickness measurements were collected at over 100 on-site wells. By also employing radiocarbon data in groundwater provided quality, technically defensible data, RORE to delineated the LNAPL plume. The data RORE generated facilitated the Navy’s justification for low-risk closure of the Fuel Farm, thereby eliminating the need for additional costly remediation system operation.
Marine Corps Base (MCB) Camp Pendleton, Oceanside, CA
RORE performs basewide compliance audits at 49 UST facilities for MCB Camp Pendleton. Work includes review of Federal, State, and local regulations applicable to UST facilities, a field audit of each facility utilizing the County of San Diego DEH Hazardous Materials Management Division UST Monitoring System Certification procedures, and preparation of a Compliance Audit Report. MCB Camp Pendleton has attained 100% compliance of base UST systems (i.e., 0% UST system deficiencies) since RORE’s 2007 and 2008 audits; this can be attributed primarily to an increased awareness and understanding of UST systems operation by base personnel and on-going system improvements.
Naval Air Weapons Station (NAWS) China Lake, CA
Under the direction of DTSC policy and environmental objectives, RORE has completed a VSI of more than 800 potential release areas (PRAs) throughout the NAWS China Lake footprint. PRAs inspected include aboveground storage tanks, underground storage tanks, hazardous waste accumulation areas, hazardous material storage areas, and miscellaneous areas (e.g., septic systems, equipment boneyards, and burn areas). The VSI is a requirement under the RCRA Part B Permit to inspect RCRA-regulated solid waste management units and areas of concern at the facility.
Riverbank Army Ammunition Plant (RBAAP), Riverbank, CA
RORE was contracted by USACE Sacramento District initially to prepare a RCRA Facility Investigation (RFI) for the RBAAP; based upon project performance, RORE was further contracted to provide a site inspection (SI), to develop innovative remedial alternatives, conduct remedial feasibility studies (FS), and develop and implement the Remedial Action Plan (RAP) to remediate PCB-contaminated pipelines and chromium VI and cyanide in soil and groundwater at the facility. RBAAP is a government-owned and contractor-operated (GOCO) facility with a RCRA Part B permit; it is also a BRAC and NPL site that requires long-term cleanup under CERCLA.
Navy Family Housing, San Diego, CA
RORE performed EBSs for more than 20 NAVFAC Southwest family housing and military sites (2,268 housing units) throughout San Diego and the surrounding area. The EBSs were completed for the Navy Public Private Venture (PPV) Program. The purpose of each EBS was to determine the environmental condition of each subject site and to evaluate the potential for environmental impact from past environmental releases of hazardous substances. ACM Surveys and/or LBP Surveys and Risk Assessments were conducted at more than 110 buildings in support of the project; this included surveys conducted at facilities designated as historical under the National Historic Preservation Act.
Naval Base Point Loma, San Diego, CA
RORE is performing non-time critical removal actions (NTCRAs) at IRP Sites 5, 9, and 23 at Naval Base Point Loma. The NTCRAs involve engineering remedial design, soil sampling, soil removal, soil cover installation, revegetation of native plant species, long-term inspection and maintenance, and preparation of detailed Work Plans and closure reports.
Naval Fuel Depot (NFD) Point Molate, Richmond, CA
RORE performs O&M activities at the Site 1 Seep Effluent System and Site 3 Groundwater Treatment Plant at NFD Point Molate. Initial work included preparation of project plans and documentation, establishment of a field office, and transition with the previous contractor. Ongoing O&M is performed and RORE is also tasked with providing technical presentations to the BRAC Cleanup Team and Restoration Advisory Board. Greater than 90% operability is currently achieved on the project, reflecting RORE’s proactive approach to technical problem solving.
Naval Base Coronado, CA
RORE is providing biovent system operations and ongoing monitoring and maintenance activities and remediation system decommissioning at underground storage tank sites at the Naval Air Station North Island (NASNI) Building 66 Area and Fuel Farm. The scoped work includes groundwater sampling and monitoring, operation and maintenance of the Building 66 bioventing system, light non-aqueous phase liquid (LNAPL) monitoring and recovery, and decommissioning of the LNAPL NASNI Fuel Farm recovery system and wells as needed. Decommissioning of the fuel recovery system consisted of decontaminating and removing aboveground LNAPL and air conveyance pipe (PVC/metal), demolition of concrete containment area, well vaults, two 12,000 gallon tanks and the oil and water separator.
