POP — 8/30/14 - 8/31115 Client— Southern California Edison Total Value - $1.2.M Client Reference — Steven Vaughan, (949) 368.788, stevie.vaughan@sce.com Project Description — Project included scoping, costing and execution of environmental site characterization studies in support of the San Onofre Nuclear Generating Station decommissioning. San Onofre Nuclear Generating Station is about 220 acres consisting of 89 structures/building with an average age of 38 years old comprising 940,000 square feet. Work scope was broken into two phases: Phase I ESA or Historical Site Assessment (HSA) and follow-on Phase II ESA including a full-blown Site Characterization of the nature and extent of non -radiological chemical constituents of potential concern (COPCs) associated with historical site operations and incidental chemical spills. Evaluations were conducted through laboratory analysis of representative samples collected from surface, near -surface and subsurface soil and groundwater. The scope also included characterization of systems, components and structures for lead -based paint (LBP), lead -containing materials (LCM), PCBs, mercury and for asbestos. Surveys of suspect _BP and LCM were conducted in general accordance with the U.S. Department of Housing and Urban Development (HUD) Guidelines for the Evaluation and Control of Lead -Based Paint Hazards in Housing adopted for industrial and commercial applications. This was initially accomplished using a hand-held X-Ray Fluorescence (XRF) Spectrum Analyzer as a rapid field screening tool to measure the lead concentrations. Bulk paint chip samples were subsequently collected and analyzed by a fixed - base laboratory to confirm the XRF initial screening results. Bulk samples for lead and asbestos evaluations were sent to AmeriSci, an EPA accredited and State -certified laboratory for analysis. A total of 1,272 samples were collected for asbestos analysis. A total of 3,791 XRF measurements were made for lead evaluations which were supplemented with 260 paint chip samples for confirmation by laboratory analysis. The ultimate objective of the site characterization was to provide an estimate of the class of waste and volume of impacted materials ultimately targeted for demolition and removal during facility decommissioning. The non -radiological team's efforts were synchronized and were carried out seamlessly with the radiological team with common project objectives and goals. The project deliverables included the HSA and Site Characterization report including Objective Evidence Binders with all supporting documentation for SCE/NRC review and approval. Title — Contaminated Soil Removal and Site Characterization Location — Marine Corps Mountain Warfare Training Center Bridgeport, CA POP — 6/29/17 — 6/29118 Client— Naval Facilities Engineering Command Southwest (NAVFAC SW) Total Value - $386,670 Client Reference — Bipin Patel (619) 532-4814, bipinkumar.patel@navy.mil Project Description — Marine Corps Mountain Training Center (MCMWTC) Bridgeport is operated by the Department of the Navy (DON) on land managed by the US Forest Service (USFS) through an interagency memorandum of understanding (MOU). The facility is located on the northern flank of Pickle Meadow, California on the eastern slope of the Sierra Nevada, within the Bridgeport District of the Humboldt-Toiyabe National Forest. During construction and upgrading the helicopter refueling facility (Hot Fuel Point), petroleum hydrocarbon contamination was found in subsurface soil under the Hot Pit at MCMWTC Bridgeport. The goal of this project was to characterize and remove contaminated soil and conduct additional site characterization to confirm that the contaminated soil has successfully been removed. The Regional Water Quality Control Board (Lahontan Region) is the overseeing regulatory agencyforthis project. Following review of the KMEA's site characterization reports, the RWQCB concurred with KMEA's recommendations for case closure. KMEA produced complete and accurate reports of its site characterization work following th�roved planning documents and protocols. As such, the RWQCB was able to provide its consensus and concurrence with KMEA's "no further action" recommendation with minimum to no comments to be addressed following its review of the deliverables. The KMEA deliverables included tabulated summaries of analytical laboratory data from soil sampling conducted, illustrative site drawings showing investigation locations, analysis of data and screening of risks posed to human health and the environment along with a refinement of the site conceptual model based on the new data acquired for the project site. KMEA provided the following services towards the fulfilment of the project objectives: • Prepared the project planning documents including the Work Plan, Sampling Analysis Plan, Site Safety and Accident Prevention Plan and received approval from the Navy and the RWQCB to proceed City of Santa Ana Page 15 June 5, 2018 Various Environmental Services RFP NO.: 18-043
