General Statement: Under the general direction of a Senior Toxicologist of the Human and Ecological Risk Office (HERO), the Staff Toxicologist independently provides expert scientific support in the areas of toxicology, human and ecological risk assessment and exposure assessment, along with a variety of more difficult tasks directly related to toxicology and risk assessment. Specific duties are outlined below, but are not limited to:
Specific Activities: Essential (E) / Marginal (M) Functions
40% (E) Risk Assessment Review - Independently prepare, review and evaluate complex Health Risk Assessments (HRA) and/or Ecological Risk Assessments (ERA), their work plans and selection of remedial alternatives to ensure the DTSC mission to protect human health and the environment is adequately evaluated and addressed. Interpret and apply public health and/or environmental standards to assess public health risks and ecological hazard from exposure to multiple media (e.g. soil, water, air, biota) contaminated with chemicals from varied types of sites and/or releases to ensure that all potential exposure pathways are considered and/or evaluated. Independently write technical memorandum clearly identifying specific site characterization or risk assessment issues, discovered during review, that require further investigation or evaluation before the characterization and/or risk assessments are considered complete. Independently write technical memoranda and provide technical consultation to DTSC Project Managers explaining rationale for HERO recommendations based on one or more specialized areas in toxicology or a closely related field; laboratory and testing procedures for toxicological investigations; principles and procedures of risk assessment; and provisions of laws, rules and regulations pertaining to the use, processing and handling of toxic substances. Provide written recommendations for complex HRA and ERA risk assessment documents, including Preliminary Endangerment Assessments (PEAs), work plans, site characterization investigations, confirmation sampling reports and feasibility studies to ensure completeness, accuracy and effective communication of quantitative predictive human health and ecological assessments. Provide technical direction to responsible parties and consultants outlining the selection of representative species in a specific environment to obtain toxicity and habitat information, by the evaluation of ecological databases and application of ecological analyses for potentially impacted sites. Independently prepare written assessments and employ categorization strategies to evaluate the human health and ecological impacts of hazardous substance releases into the environment and determine what remedial actions, permit conditions or ingredient substitutions are necessary to protect human health and the environment.
30% (E) Hazard Assessment - Independently review and evaluate existing toxicological information such as acute and chronic toxicity, indicators of carcinogenicity, port-of-entry effects and the array of observed and potential toxic endpoints in support of DTSC novel programs such as the Green Chemistry Initiative (GCI) Toxicity Information Clearinghouse and the GCI Safer Consumer Products. Provide technical review of toxicity criteria and hierarchical classifications proposed for inclusion in California regulations in support of such programs to DTSC teams and CalEPA teams. Ability to search, evaluate and summarize toxicity and/or exposure data extracted from Federal (e.g., U.S.EPA ACToR, U.S. EPA IRIS) and International (e.g., European Union REACH, European Union ECETOC, Nordic Countries SPIN) databases to support DTSC and CalEPA teams. Independently review and evaluate the ability of innovative techniques such as in vitro testing, in silico estimation, quantitative structure activity relationships (QSARs) and computational toxicology to provide data of sufficient quality and certainty to meet DTSC novel project needs such as: 1) assess potential health impacts of site specific hazardous substance releases and/or categorization of human health or ecological hazard associated with general releases to the environment; 2) provide hazard characterization of consumer products with potential human health and/or ecological impacts; and, 3) prepare expedited assessments during acts of chemical or biological terrorism in order to determine health-protective cleanup goals that allow re-entry or re-use of vital State facilities.
10% (E) Interagency Coordination - Participate in intra- and extra-Department investigation, coordination, team meetings, work groups and Federal (e.g., U.S. EPA, U.S. F&WS) and California (e.g., OEHHA, Regional WQCB and California DFW) advisory groups to develop and maintain knowledge of current strategies and techniques necessary to provide screening and categorization of potential adverse effects on human health and ecological systems; Evaluate appropriate data gathered from interagency coordination and similar toxicological resources to provide manager a written summary of essential data that could affect application to human health and/or ecological risk assessments.
5% (E) Cost Recovery and Enforcement Support - Prepare more difficult risk assessment findings and risk based remedial decisions made by DTSC to support case development, cost recovery decisions, and prosecution of hazardous waste offenders, enforcement investigations, and acts of chemical or biological terrorism. Present findings in administrative hearings or in court proceedings. May testify and an expert witness in hearings and court procedures.
5% (E) Public Communication - Prepare and present human health and ecological risk assessment findings and summaries to the general public, news media, local and state agencies, other concerned or interested parties, at public meetings.
5% (M) Conduct Project Activities - Conducts, coordinates and prepares reports for the Senior Toxicologist on project status, budgets, resource projections, and other reports as necessary; adds new sites and maintains schedules and information on existing sites in DTSC’s EnviroStor database: identifies possible project delays and actual delays, determines cause and provides proposed solutions to the Senior Toxicologist; prepares highlights/briefings for upper management on important projects; and maintains current daily log.
5% (M) Training - Provide human health and ecological risk assessment training to DTSC and other agency staff to provide project managers with an understanding of the most current principles and practices of risk assessment to enable them to independently make informed decisions on technically less complex issues and recognize sensitive species and habitats, and human health risks as appropriate. Participate in drafting technical bulletins and guidance where indicated.
