EXPERIENCE SUMMARY

Dr. Ozaki has been active in environmental consulting for the past twenty years. He is a public health specialist engaged in health risk assessment work for hazardous waste sites. He developed and managed LevineFricke's Risk Group and is currently the Director of the Public Health Risk Assessment Services at (SOMA). His experience includes providing both technical and management support for EPA Superfund endangerment assessments and baseline risk assessments in Region IX, as well as for State Superfund baseline risk assessments in California, and other states. He has prepared site-specific quantitative multimedia risk assessments as part of the RI/FS process for various sites on EPA's National Priorities List (NPL). As part of these evaluations, Dr. Ozaki has performed data evaluations in order to identify chemicals of concern, developed toxicological profiles, performed exposure assessments and quantified the risks associated with the site. Dr. Ozaki has also provided technical support to the EPA in Region X on a multimedia exposure assessment model to verify soil remediation at Federal-lead hazardous waste sites. His work included the preparation of algorithms required to quantify risk at various stages of remediation.

Dr.Ozaki has also prepared various types of quantitative risk assessments for regulatory compliance purposes at both the State and Federal levels. They include permitting requirements for the construction of cogeneration and municipal solid waste facilities; development of soil remediation levels (SRL) for various hazardous materials including: volatile organic compounds (VOCs), inorganic metals, agricultural chemicals, polychlorinated biphenyls (PCB), petroleum hydrocarbons; and preparation of documentation of remediation. Recently, he has prepared a quantitative risk assessment for a client who requested a regulatory compliance evaluation under the Safe Drinking Water and Toxic Enforcement Act of 1986. The project involved an extensive data adequacy evaluation, the identification of chemicals known to the State to be a carcinogen or a reproductive toxicant that were discharged on-site by the client, preparation of a source release inventory, the development of a work plan to collect air samples and the preparation of a quantitative risk assessment.

Dr. Ozaki has completed a large number of baseline risk assessments for California Bond Sites (California Superfund sites) and other PRP-lead sites in California. These risk assessments demand technical expertise and attention to detail specific to guidelines and policy issues particular to various regulatory agencies in the State of California. Dr. Ozaki's experience has established him as an effective consultant in representing client needs and presenting technical data in compliance with regulatory agency requirements.

As an important agricultural producing State, risk issues related to the use of agricultural chemicals is a concern. Dr. Ozaki has applied his experience in the risk evaluation of pesticides, herbicides, fungicides, and algicides in performing risk assessment of agricultural chemical-affected lands. The use of former agricultural lands for residential, commercial, and industrial development has prompted the California Department of Health Services (DHS) through the Department of Toxic Substances Control to look closely at potential health affects due this type of development. This concern has carried over to the California Environmental Protection Agency (Cal EPA). The absence of regulatory guidelines specific to agricultural chemicals have placed increasing emphasis on technical expertise in addressing Cal EPA concerns. Dr. Ozaki has been very effective in working with Department of Toxic Substances Control and with various county and municipal health departments in performing these types of risk assessments.

Dr. Ozaki has performed over 50 environmental regulatory compliance audits primarily in California and throughout the United States. Clients have included companies from within the following industries: high tech electronics, electronics manufacturing, communications, metal plating, automobile, lumber and wood treatment, nuclear manufacturing and power generation. Several audits were also performed for the U.S. Department of Energy and Department of Defense. Dr. Ozaki has also performed real estate acquisition and divestiture audits for the presence of hazardous and toxic materials. Dr. Ozaki was member of an auditing team that performed an extensive, year-long RCRA audit of a large DOE nuclear reservation in the Pacific Northwest. He has also performed OSHA-type audits at NPL-listed sites under the various Superfund contracts.

Dr. Ozaki has been the Regional Health and Safety Officer for two major environmental consulting companies in the San Francisco Bay area and the Corporate Health and Safety Director for another. He has extensive experience in the health and safety aspects of hazardous waste management and remediation programs in a large variety of both governmental and private industry projects throughout the United States. For two years, Dr. Ozaki has also served as the Regional Health and Safety Director for EPA Region X, under the REM II Superfund Program.

Dr. Ozaki's experience includes:
