Northern Dynasty and Pebble Partnership have invested more than $150 million over seven years to create one of the most extensive environmental databases ever assembled for a resource development project in North America.
Areas studied include climate, surface and ground water hydrology, water quality, wetlands, fish and aquatic habitat, wildlife and terrestrial habitat, land and water use, socioeconomics and subsistence. This substantial database has been used extensively in engineering design and will be used to inform the upcoming permitting process and the development of an Environmental Impact Statement.
