Brett Tiller – CEO/Principal Scientist

Professional Summary

Brett Tiller

Brett Tiller is a principal wildlife scientist/ecological assessment specialist with more than 25 years of experience characterizing wildlife populations, conducting biological resource reviews, and assessing ecological impacts from project operations (including hazardous chemical contamination) on aquatic and terrestrial ecosystems throughout the United States. Brett routinely oversees multi-disciplinary teams involving ecological risk assessments, biological and cultural resources management, site characterization of contaminants, and directs research and monitoring of wild mammals, birds, fish, macro-invertebrates, reptiles, and amphibian populations to document their life history characteristics, distributions, and abundance.

Brett also develops ecological mitigation plans to assure operational objectives are met while implementing conservation measures needed for ecological compliance and Endangered Species Act requirements. He frequently conducts informal and formal consultations with the U.S. Fish and Wildlife Service (USFWS), the National Oceanic and Atmospheric Administration (NOAA), and with Washington State Department of Fish and Wildlife (WDFW) representatives.

He has written or coauthored a number of peer-reviewed manuscripts and technical reports and presented this information to clients, regulators, stakeholders, to members of the public, and at national and international society meetings.

In 2005, Brett established Environmental Assessment Services (EAS), LLC, to pursue and develop advanced techniques for sampling and characterizing environmental media. His goal: deliver to his clients a reality check of environmental quality, and, likewise-a reliable foundation for operational and cleanup decision-making. EAS has since become the prominent small business collecting the relevant biological data in support of the U.S. Department of Energy's environmental cleanup mission at the Hanford Site. His extensive knowledge of shrub-steppe flora and fauna, as well as his understanding of Hanford security, infrastructure, and politics were key to the award of several sole-source contracts to his company.

Brett maintains an extensive health & safety program for EAS (consistent with 10CFR 851), manages projects, conducts field- and lab-based wildlife surveys, and oversees a large number of field and laboratory technicians, undergraduate and graduate students, scientific staff, and external consultants in environmental resource management and research. For 19 years, he has successfully maintained WDFW, USFWS, and NOAA scientific fish and wildlife collecting permits supporting hazardous waste site investigations.

Relevant Work Experience

EAS, Richland, Washington, CEO/Principal Scientist, 2005- Present

EAS Project Lead for several large programs:

  • Environmental Surveillance (ES), Ecological Monitoring & Compliance (EMC), and Cultural & Historic Resources Projects for Mission Support Alliance Project Lead supporting assisting in the development of ES procedures and EM&C monitoring plans and Threatened and Endangered (T&E) species management plans. Brett is also conducting and providing senior-level oversight of field studies on the Hanford Site. This work is part of the successful transition of the PSRP program to MSA.
  • Mapping contaminated groundwater upwellings as part of Remedial Investigation/Feasibility Studies for CH2M Hill Plateau Remediation Company
  • Ecological Compliance activities for the Hanford Site River Corridor Cleanup Contractor
  • Small mammal contaminant characterizations for Washington River Protection Systems
  • Field Sampling Events for the Umatilla Chemical Agent Disposal Facility’s Comprehensive Monitoring Program
  • Field Surveys and Sampling, for NOAA, to assess damage to the natural resources from the MC252 Deepwater Horizon Gulf of Mexico Oil Spill

Pacific Northwest National Laboratory, Richland, Washington, 1990-2004

While at Pacific Northwest National Laboratory, Brett was involved in characterizing natural resources throughout the country, developing new wildlife monitoring technologies, and assessing ecological impacts from federal operations such as the U.S. Department of Defense, U.S. Army Corps of Engineers, and U.S. Department of Energy (DOE).

He led the first comprehensive contaminant-based impact investigation on Hanford Site wildlife. This study, conducted in the early 1990s, focused on assessing possible causes of sterility observed in a portion of the male mule deer population. He also led the first study involving capture and tagging of American white pelicans (State endangered) in Washington State. The purpose of this study was to assess potential consumption of juvenile salmonids by the American white pelicans as the fish pass though a major hydroelectric facility, the McNary dam. This was a particularly sensitive investigation because both the predator and prey were listed as special status species.

Brett's work for DOE included developing sampling and analysis plans and collecting/processing environmental samples for analyses of contaminants in soil; native vegetation; agricultural products (fruits, vegetables, dairy products, honey, and wine); avian species (chukar, pheasants, quail, mallards, geese, and avocets); mammals (deer mouse, pocket mouse, harvest mouse, rabbits, mule deer, and elk); and fish (sculpin, suckers, bass, carp, and salmon); and mollusks. He frequently interfaced with, and presented his findings, to the client, regulators, stakeholders, and to members of the public. In addition to publications and peer-reviewed manuscripts, selected highlights of his work have been published annually in the Hanford Site Environmental Reports.
