Research for the Pebble Project Environmental Baseline Document (EBD), which represents one of the most comprehensive environmental study programs ever conducted for a natural resource project in Alaska, was undertaken by more than 40 widely recognized and respected independent companies and research firms.

  • 100+ scientific experts
    • Engineering groups, laboratories, technicians and support services
  • Selected for specific areas of expertise and Alaskan experience

The EBD was written and certified by third-party study authors associated with the main categories of environmental research, with the exception of the introductory chapter, which was written by The Pebble Partnership.
