Travis Kline is a Senior Principal Toxicologist based in Washington, D.C. with more than 25 years of experience focused on human health risk assessment and applied toxicology.
Travis has authored and provided critical review of hundreds of chemical and radiological human health and ecological risk assessments, addressing a comprehensive set of target constituents at a wide variety of federal facilities (e.g., DOD, DOE, FAA) and private sector industries, including ports and harbors, airports, mining, mid-stream oil and gas, specialty chemical manufacturing, and consumer product manufacturing. Travis has specialized expertise in the assessment of dioxins/furans, PAHs and PCBs. Travis has developed novel approaches to the characterization of problematic exposures to dioxin and dioxin-like constituents, PAH exposures, and the characterization of exposures to pesticides and chlorinated solvents. Travis currently provides expert risk assessment support for litigation actions, including cost allocation, for large, multi-PRP CERCLA sites, such as the Portland Harbor Superfund site. Travis is the primary author of the health-mediated cost allocation for a large multi-PRP sediment Superfund site in New Jersey. Travis has expertise in vapor intrusion assessment and is active on investigations surrounding problematic constituents (e.g., subchronic inhalation exposure to TCE) and emerging contaminants, such as PFAS. Travis consults with specialty chemical manufacturers to address TCSA requirements, product development challenges, and data gap assessments, with specialized expertise in plasticizer and phthalate exposure, focusing on endocrine disruption and reproductive/developmental endpoint assessment. Travis is also active on consumer product safety assessments, including Prop. 65 hazard assessments, SDS development, and product stewardship services (e.g., Hazard and Safety Assessments, Regulatory Review, GSH Classification, CPSC labeling).
Travis was selected by U.S. EPA to chair the external peer review of the Human Health Risk Assessment Protocol for Hazardous Waste Combustion Facilities. He authored Puerto Rico's Risk-Based Corrective Action Program Manual and New Mexico's Soil Screening Guidance; oversaw beta-testing of Virginia's Unified Risk Assessment Modules ; and developed U.S. EPA's activity-based sampling and provisional toxicity criteria for asbestos exposures. An invited lecturer at U.S. EPA's National Forum on Vapor Intrusion, he has instructed continuing education courses for the American Bar Association, and served as technical advisor to update U.S. EPA's Delisting Risk Assessment Software (DRAS). He authored the first state- or federally-promulgated Alternative Assessment Report for bisphenol-A. Travis' recent support on behalf of Eastman Chemical Company to clarify neurotoxicological implications and respiratory sensitization for a non-orthophthalate plasticizer was nominated for a Presidential Green Chemistry Award.
