| Brownfields Redevelopment Projects, Port of Oakland, California: Program Manager for two consecutive as-needed contracts to provide a wide variety of environmental compliance services to the Port of Oakland. Over 60 projects completed to-date, including 11 investigations for redevelopment projects at the Oakland International Airport, a Maritime berth, and two industrial properties that have since been redeveloped as parks. Investigations entailed designing and implementing soil and groundwater sampling to provide the data needed for evaluating risk during and after redevelopment and/or for predetermining soil disposal options during development. Risk assessments conducted in accordance with the SFWB’s Environmental Screening Level (ESL) Tier 1 and Tier 2 risk assessment guidance. All work conducted on time and on or under budget and to the Port of Oakland and SFWB’s satisfaction. Brownfield Site Investigation and Risk Assessment, Fortune 100 Semiconductor Manufacturer, Santa Clara, California: Program Manager for this client for the past twelve years. Our initial investigations at this undeveloped site were follow-up to previous sampling that had identified metals contamination. Conducted several phases of soil sampling to determine the nature, extent and likely source of the contamination. Also performed air modeling to assess the need for Proposition 65 warning, and determined that no such warning was warranted. Based on soil investigation results, presented data to the California Department of Toxic Substances Control (DTSC) and negotiated a Voluntary Cleanup Agreement (VCA) for our client. Work under the VCA included risk assessment, Removal Action Workplan (RAW), RAW implementation, and public participation activities. Through the risk assessment, conducted in accordance with Preliminary Endangerment Assessment (PEA) and other DTSC guidance, demonstrated that the RA could be limited to institutional controls to ensure the existing clean cover remains intact. Cost for implementing this alternative was $1M less than other alternatives. RAW approved by DTSC and the public. Prepared all public participation documents and the deed restriction, and prepared and implemented Operations and Maintenance (O&M) and Soil Management Plans. Brownfield Environmental Investigation and Risk Management, Former US Army Disciplinary Barracks, Lompoc, California: Program Manager for investigation and risk evaluation of this former Army facility targeted for redevelopment by the federal Bureau of Prisons (BOP). Sites included two landfills, a vehicle wash rack/grease rack area, an incinerator, and a skeet range. Work scope included soil, soil gas, ground water, and surface water investigations; human health and ecological risk assessment following USEPA guidance; preliminary evaluation of remedial options for two of the areas; and, negotiations with the U.S. Army, BOP, USEPA, Central Coast Water Board (CCWB), and County of Santa Barbara for No Further Action on the remaining sites. Environmental Investigation and Risk Screening, DOE-funded Research Facility, Davis, California: Managed investigation of 3-acre dog pens used in radiological testing for almost 30 years. Diffuse, low-level radionuclide, metal, and pesticide contamination presented difficult challenge for investigation design and risk management planning. Used field screening methods, a phased investigation approach, statistical methods, and risk-based action levels to cost-effectively demonstrate that No Further Action is required for the dog pens soil. Project required frequent presentations to and negotiations with multiple stakeholders with varied interests, including USEPA, Central Valley Water Board (CVWB), DTSC, Department of Health Services (DHS), and University of California at Davis, all of which approved the plans. Hydrogeology Projects, City and County of San Francisco, California: Provided site characterization and environmental compliance expertise on several projects under an as-needed environmental services contract for this client and assisted in negotiations with the SFWB, CVWB and DTSC on several surface water, ground water and sediment issues related to these projects. One project involved the proposed dredging of sediment with high copper levels from a reservoir and placement of the sediment near another surface water feature. Regulatory concerns were addressed through sediment and water quality sampling and biological and human health risk assessment. Hydrogeologic Investigation, DOE-funded Research Facility, East Bay, San Francisco, California: Managed investigation of 120-acre research facility in California Coast Range. Worked jointly with team of scientists from the facility. Over 100 Solid Waste Management Units (SWMUs) and other Areas of Concern with a wide range of potential contaminants were identified and investigated. Investigation methods included wipe sampling, surface soil and water sampling, active and passive soil gas surveys, geophysical surveys, soil borings, and nested well installation. RCRA Facility Assessment and RCRA Facility Investigation workplans completed.
