Brownfields Redevelopment and Hazardous Site Management
Representative Projects
DEW-Line Risk Assessments, Alaska
Oversaw risk assessments at eight distant early warning (DEW)-Line sites on the North Slope of Alaska for US Air Force Center for Environmental Excellence. The project involved field sampling and site characterization, interim remedial action, human health and ecological risk assessment, remedial investigation and feasibility studies. *top
Analysis of RCRA Hazardous Wastes Containing PCBs, Washington, DC
Provided project management assistance to US EPA's Office of Solid Waste on a project designed to determine the types and quantities of RCRA hazardous wastes containing PCBs being land disposed. This project involved characterization of the wastes, identification of their sources and determination of current waste management practices. *top
Training Program in RCRA and CERCLA Cleanup Processes, Ohio
For the Department of Energy, designed and conducted a training program for facility personnel addressing CERCLA and RCRA cleanup processes in order to provide a framework for strategic environmental planning and ensure legally sufficient cleanup. Reviewed facility EMS documents as well as Superfund and RCRA assessments and other guidance documents. Through the training course, provided a thorough understanding of underlying Superfund requirements, discussed statutory definitions, provided overviews of removal actions and risk assessments, and reviewed document control procedures and methods of gap analysis and integration of cleanup processes. *top
Tribal CERCLA Support, Oregon
Providing support to the Confederated Tribes of Grand Ronde, Siletz, Umatilla, and Warm Springs to address injuries to tribal resources at the Portland Harbor, Taylor Lumber and McCormick and Baxter National Priorities List sites. Reviewing site investigation information at the three sites to identify where tribal resources have been threatened or harmed. Assisting the tribes in prioritizing cleanup actions at the Portland Harbor sites. Evaluating proposed remediation alternatives to determine effectiveness. Representing the tribes at key site meetings and conference calls. Reviewing and providing comment on key documents, including site characterizations, environmental evaluations, proposed plans, work plans, project memoranda, remedial investigation/feasibility studies, quality assurance plans, operation and maintenance plans, health and safety plans, contingency plans, records of decision, remedial design documents, remedial action plans and human health and ecological risk assessments. *top
Analysis and Oversight of the RI/FS for the White King/Lucky Lass Superfund Site, Oregon
Provided review and oversight of field investigations, remedial investigation (RI), risk assessment, treatability studies and a feasibility study (FS) for the cleanup of a Superfund site in Northeastern Oregon. Of particular concern were sediments in ponds dominating the mining sites. *top
Site Assessment and Brownfields Redevelopment under MTCA and CERCLA, Washington
Assisting the City of Aberdeen, the Washington State Department of Ecology and US EPA in cleaning up a Brownfields site on the state Hazardous Sites List. The site is contaminated from historical use as a woodwaste, dredge spoil and garbage landfill and from truck maintenance. Analyzed recent and historical data in the RI/FS, conducted human health and ecological risk assessments, reviewed cleanup levels and completed a feasibility study to identify remedial approaches to the localized soil and groundwater contamination. Also leading a community outreach program to educate the community about the cleanup process and to garner support for a redevelopment project that will enhance the local economy. *top
Tribal Assistance in the NPL Listing Process and Sediment Standards Development, Washington
Working with the Confederated Tribes of the Colville Reservation to address contamination in the upper Columbia River watershed. The site has been contaminated by historic and current discharges from mines, milling operations, smelters and a pulp and paper mill. Several fish consumption advisories have been issued and the bioaccumulation of toxics has impacted tribal fisheries resources. Providing support to the Tribes for all phases of the CERCLA process at the upland sites and contaminated sediment sites. This effort includes reviewing preliminary assessments and site investigation reports; helping the Tribes navigate the NPL listing process; reviewing Sampling and Quality Assurance Plans; providing analysis of sediment, soil and water data collected by US EPA and others; meeting with and negotiating with regulators; recommending studies to complete a thorough ecological and human health risk assessment; and providing advice on the remedial investigation data collection process to set the stage for a natural resource damage assessment. *top
Technical Support Regarding Hazardous Waste Facility Cleanup and Closure, Washington
Assisting the Georgetown Community Council with the cleanup and closure of a hazardous waste treatment and storage facility in the Georgetown neighborhood of Seattle. Reviewing and commenting on technical analyses, sampling plans, interim measure work plans and facility assessments. The major contaminants of concern are volatile organic compounds in groundwater and indoor air, including vinyl chloride and benzene. *top
Biological Opinion and Systems Operation Review, Washington
On behalf of the Confederated Tribes of the Colville Reservation, prepared comments for submittal to the Bureau of Reclamation regarding the Tribes' comments and concerns with a biological opinion/systems operation review of proposed changes to operations at Grand Coulee Dam. The proposed changes involved altering the drawdown amount and schedule for the reservoir (Lake Roosevelt) behind the dam. Analyzed impacts on tribal fisheries and contaminated sediments in the lake and investigated the effects on air quality during drawdown when contaminated bank sediments are exposed to sun and wind. Coordinated comments of various tribal members, consultants and lawyers. *top
Asarco RI/FS and Risk Communication, Washington
Provided project oversight assistance from the initial investigations through the Record of Decision. The project included field investigations and sampling, data management, remedial investigation, risk assessment, treatability studies, consideration of applicable or relevant and appropriate requirements (ARARs) and the feasibility study. Also assisted in preparing materials for and participating in public meetings regarding risks and benefits of potential cleanup strategies. Based on the results of the communication efforts, a strategy was developed for the required monitoring and cleanup at the site. *top
Site-Specific Risk Assessments and Risk Communication
Provided management assistance on a number of site-specific risk assessment projects for private clients in the United States and Canada. Projects involved exposure assessments, toxicity assessments and risk characterization along with discussion of uncertainties in the evaluation, and presentations to involved stakeholders. Projects also included site-specific investigations, determination of contaminants of concern, development of conceptual site models, assessment of sampling plans and calculation of site-specific cleanup requirements to satisfy regulatory and health-based requirements. *top
