In depth understanding of the facility operations and corporate philosophy enabled the development of a unique strategic plan that greatly reduced project costs.

Pneumo-Abex Aerospace Co., Oxnard, California. Project Director responsible for overall project strategy, regulatory negotiations and evaluation and implementation of investigation and remedial measures at this former aerospace manufacturing facility. The site activities were conducted under an Administrative Order and a lawsuit. This project required evaluation of past operating history, retrofitting and optimizing existing remediation system, implementing in situ remedial alternatives, and providing litigation support. Our services were directly responsible for savings of several millions of dollars and provided the client with strict cost control and project management measures.

Fuller-O’Brien Paints, San Francisco, California. Project manager for a soil and groundwater investigation at a paint manufacturing facility, under a RCRA 3008h Order. The facility operations dated back to the late 1800’s. The project involved the evaluation of past facility operations, closure of surface impoundments and SWMUs, remediation of lead and SVOC impacted soil and evaluation of ecological risks to sensitive wetland and bay margin environments. Innovative regulatory approach utilized the CAMU policy to stabilize impacted soils and save the client nearly a million dollars in remedial costs.

Remco Hydraulics, Willits, California. Project director responsible for implementing project strategy and conducting regulatory interface of soil and ground water investigation and remediation activities at the former pneumatic cylinder manufacturing and chrome plating facility. This NCP compliant RI/FS required implementation of Interim Remedial Measures, the development of an RI/FS workplan and the implementation of the approved workplan within a defined set of financial resources. We were successful in controlling the monthly costs to accommodate all of the required goals. The project involved intense legal issues, including citizen suits.

Lincoln Properties, Ltd., Stockton, California. Project manager responsible for all field oversight activities associated with an NCP compliant RI/FS at a prominent shopping center where chlorinated solvents from dry cleaning operations impacted the soil and groundwater beneath the site. Our services included providing litigation support that resulted in a guaranteed remediation at no out of pocket cost to our client. Additionally, the litigation resulted in all oversight costs being repaid to our client. These oversight responsibilities included the review of comprehensive project plans, extensive monitoring of the fieldwork (most of which was completed during night-time hours) and the evaluation of project data and remedial activities.

Solvent Blending Facility, Newark, California. Project manager on a former chemical blending facility impacted with chlorinated solvents. Project has included site investigation, remedial design, and treatment system operation and maintenance. Our involvement has saved the client tens of thousands of dollars by implementing a low cost, low

City of Lodi, Lodi, California. Worked as the client manager to the City Manager and City Attorney responsible for overall project deliverables, data collection, data synthesis and presentation, agency interactions, litigation support and community relations. Project involved determining the fate and transport of chlorinated solvents present in the City’s municipal supply well and pursuing the parties responsible for the cleanup. Responsibilities have included the identification of over 180 locations, with multiple historical owners and operators, that may have caused or contributed to the contamination, conducting the environmental investigation, and providing litigation support to the City of numerous matters.

EnviroForensics has represented both buyers and sellers to facilitate property transactions. Responsibilities have included developing cleanup costs and negotiating site remediation objectives with regulatory agencies, providing guaranteed cleanup financing, and maximizing the assets of environmentally impaired property. Many of the projects involved identifying historical owners and operators, and their insurers, working with legal counsel to conduct due diligence activities, conducting site investigation and cleanup activities, and conducting technical and fact finding research to develop project upside.

Global Insurance Recovery, National Program. Lead forensic and fact-finding expert on a global insurance litigation associated with eleven test cases from sites located across the United States. Project involved collecting information from all of the manufacturing facilities, evaluating the existing soil and ground water conditions, identifying significant spills and releases that impacted the environment, identifying key witnesses, reviewing depositions, and assisting counsel in the technical presentation of the case.

Innocent Landowners, Locations throughout United States. Lead technical and forensic expert on numerous contaminated properties that are owned by corporations, LLCs and LLPs that have not contributed to the environmental impact. The projects have involved evaluating the existing soil and groundwater conditions, the identification of responsible parties, collecting historical site information (e.g. waste handling practices, building plans, regulatory records), identifying key witnesses, and assisting legal counsel in building and supporting the technical merits of a case. The litigation would force the responsible parties to cleanup the site. These efforts maximize the value of the property while minimizing our clients out of pocket expenses and reducing their liability and exposure.
