Authored expert reports, led expert teams, and provided project management and client communication for allocation of sediment cleanup and natural resource damages. Represented client as technical expert in online (COVID-era) mediation meetings with averse parties. Supported clients by compiling a multi-disciplinary expert team, converging expertise in air modeling, fingerprinting, sediment transport, and analysis of sewer discharges. Also led the development of allocation strategies, prepared attorney-directed documents, communicated key findings to clients, and oversaw keyword tagging of more than 30,000 documents within a document repository. Topics included historical pulp and timber mills, sewer conveyances, vessel operations, and chemical forensics of PAHs, PCBs, and dioxins. Supported clients in NRD settlement by deciphering trustees’ model and presenting key facts about municipal discharges to certain footprints, leading to an agreement well below the original proposal.

Provide on-call technical support to end client for harbor-related and other environmental matters.
Superfund Cleanup and NRDA Allocation, Portland, Oregon Serving as principal in charge and leading expert team to develop technical reports for allocation within a sediment site involving in excess of 100 participating and nonparticipating parties.  As lead expert on more than 10 reports, working closely with counsel, developed historically relevant opinions for 1940s to 1970s era steel mill, examining several other, often overlooked source areas, including streets, sewers, upstream parties, and lesser-known industries.  Managing a team of 20+ experts and several support staff to produce expert reports and reply documents over an overlapping deliverable schedule within three phases each for six river segments.  Contributed to several expert reports in addition to those prepared as lead author.

Tasks to generate client deliverables include writing and reviewing expert team’s reports and developing mass loading estimates and release score methodology in collaboration with technical staff and counsel.  Reviewed and responded to opinions advanced by averse party experts, under a tight time frame, involving rapid synthesis of petitions submitted by other parties.  Deliverable preparation also included collaboration with industry expert, extensive photographic research, forensic evaluations for PCBs and dioxins/furans, and topographic and chemical examination of fill materials.

Early supporting tasks during sitewide RI/FS and pre-design investigation stages included development of sampling strategy and technical review with an eye toward the client’s perspective of work products produced by common consultants. These products include data compilation, chemistry interpolation, sediment deposition evaluations, cost estimates, and historical summaries. Compiled and synthesized relevant information to respond to disclosure questionnaires and supplemental information requests and to generate comments on allocation team-generated deliverables. Evaluated trustees’ NRD proposal relative to sediment chemistry, sources, and operational history to prepare response documents, cross-checking trustee calculations and responding to incorrect assumptions, with more than 50 percent reduction in damages allocated to client. Communicated findings to end client and attorneys and participated in multiple collaborative teams with counsel.

Sediment Investigation

Superfund RI/FS, Record of Decision, Predesign Support, Portland, Oregon Reviewed, on behalf of an industrial client, RI/FS and pre-design evaluation documents prepared for two PRP groups and EPA. Provided detailed review and comments on EPA’s proposed plan and record of decision, for the client individually and as part of a PRP Group. Supported development of predesign sampling scope and data evaluations to document current site conditions and inform the conceptual site model and remedial approach. Provided input on associated sampling plans, EPA communication materials, remedial design guidance, and data reports by common consultants.
Lower Duwamish Waterway Predesign Studies, Seattle, Washington Interviewed waterway users to identify highly trafficked areas of the site and berthing areas. Compiled lines of evidence for natural recovery designations in surface sediments. Evaluated changes in sediment chemistry to support natural recovery evaluations in order to revise prior feasibility study designations with new data. Updates to recovery category designations were considered with respect to new information gathered after the feasibility study. Also evaluated changes in sediment chemistry to support natural recovery evaluations. Communicated findings to client and directly to EPA and U.S. Army Corps of Engineers.
Various CERCLA Site Support Worked on various Integral teams writing nature and extent text, developing cost estimates, managing field sampling preparation, and overseeing map and data table production. Work has involved communication among members of multiple teams and contractors as well as completion of quality assurance steps for deliverables. Sites include Berry’s Creek (New Jersey), San Jacinto River Waste Pits (Texas), Passaic River (New Jersey), and Frenchtown Mills (Montana).

Project Management

Former Wood Treating Site, Remedial Action Optimization, Springfield, Missouri Managed technical team developing work plans to collect data related to pump-and-treat remedy optimization and offsite migration from a former creosote wood treating facility. Three work plans were under development simultaneously to respond to stakeholder and neighboring property concerns and to address source control. Managed data collection and resident communications related to vapor intrusion, lawn soils, and stormwater basin water levels. Under a related scope, provided contract project management services to the client for contractor work products, required reporting to the state agency, internal team meeting planning and reporting, and agency/stakeholder meeting planning.
MTCA Evaluations at Neighboring, Downgradient Properties, Woodinville and Port Angeles, Washington For two separate clients, evaluated impacts to downgradient properties defined as a part of an MTCA site.
