Remedial Design

Initial Study/Mitigated Negative Declaration (IS/MND) for the Pier 39–43½ Remediation Project, San Francisco, California Assisted with development of an IS/MND for a project designed to remove contaminated sediment from San Francisco Bay. The lead agency was the San Francisco Bay Regional Water Quality Control Board (Water Board). CEQA regulations were interpreted and incorporated for evaluation of a wide range of potential environmental impacts.

Planning and Permitting

CEQA and Permitting for Various Sewer Rehabilitation Projects, Marin County, California Provided CEQA, permitting, and biological support for Ross Valley Sanitary District on several infrastructure projects in Marin County. Aided in the development of the IS/MND, CEQA addenda, and Categorical Exemption/Notice of Exemption documents for various sewer rehabilitation projects. Specific areas of environmental analysis included aesthetics, geology and soils, hazardous materials, noise, public services, and recreation. In addition, conducted required natural resource surveys to identify biological resources present within the project site and conducted required analyses and reporting related to local, state, and federal jurisdiction over the project site and significance of project-related impacts to biological resources. Prepared a project-specific biological resource analysis to analyze potential for significant impacts to biological resources that may result from the remediation project.
Woolsey Road Riparian Restoration Project, Windsor, California Conducted a forensic wetland delineation and supported the preparation of the corresponding report.
Port of San Francisco Sediment Remediation Project (Piers 37–43½), San Francisco, California Supported adherence to CEQA requirements and permitting for a project involving multiple pier areas along the San Francisco Waterfront. The project will include dredging and capping of PAH-contaminated sediment with the Water Board as the lead agency for CEQA. Permitting agencies include the U.S. Army Corps of Engineers, Water Board, and San Francisco Bay Conservation and Development Commission with consultations on essential fish habitat and endangered species with the California Department of Fish and Wildlife, NOAA/National Marine Fisheries Service, and U.S. Fish and Wildlife Service.

Conducted document review and research of relevant historical reports. Wrote the Level I site assessment, compiled all necessary components, and coordinated with the client for review and approval.

Cost Allocation

Portland Harbor Superfund Site Allocation, Portland, Oregon Supported cost allocation efforts for the Portland Harbor Superfund site. Conducted historical research focused on relevant properties within the Superfund site.

Human Health Risk Assessment

Human Health Risk Assessment for Former Creosote-Based Wood Treatment Facility, North Carolina Contributed to a large baseline risk assessment to address releases of pentachlorophenol, carcinogenic PAHs, petroleum hydrocarbons, and dioxins and furans during historical operations at a former wood treatment facility. Assisted with the evaluation of human health endpoints for exposure to impacted soils and groundwater related to residential, commercial, and recreational land uses, and summarized resulting cancer risks and noncancer hazards.
Redevelopment Projects, Multiple Sites in California Contributed to human health risk assessments for multiple redevelopment projects in California. Contaminated sites included pesticide-impacted agricultural land, several industrial sites affected by volatile organic compounds, and other sites impacted by hazardous chemicals. Assisted in the evaluation of human health risks via direct contact and vapor intrusion into buildings.
