The course is designed to provide an overview of mining and NEPA and is geared towards how tribes can participate in the NEPA process. Part 1 will educate participants on the major steps in mine development, exploration, types of hardrock mining, and mineral processing. Presenters will provide an engaging look into the world of hardrock mining. Participants will walk away with a basic understanding of the types of mining and gain a common language to communicate about mining in their geographic area of interest. Participants are encouraged to ask questions.

You may be interested in the May 12 archive of Part 1 from this course on Mining Fundamentals, the May 24 archive of Part 2 on Mining Environmental Concerns and Issues and the June 8 archive of Part 3 on Regulatory Process & How the Public and Tribes can Engage.

Patty McGrath has 30 years of mining experience; including seven years as a metallurgical engineer at the beginning of her career and 23 years in environmental regulation (19 years with EPA and 4 years in consulting and industry). Patty has expertise in the application of the National Environmental Policy Act, Clean Water Act, and federal consultation laws (Endangered Species Act, National Historic Preservation Act) to mining projects (from exploration through closure) from both the regulatory agency and industry perspective. She has knowledge of and experience with State regulation of mining practices as well. While mine environmental review and permitting is her specialty, Patty also has experience on the cleanup side having managed and participated in teams evaluating and cleaning up sites under CERCLA. Her work has required extensive coordination with federal and state agencies, consultation with tribal governments, and communication with the public and stakeholders. During her time with EPA, Patty managed the EPA Region 10 Mining Team and co-lead EPA's National Mining Team and was involved in developing regional and national regulation and guidance. She is currently the permitting manager for Donlin Gold LLC..

Patty has a B.S. in Metallurgical Engineering from the Colorado School of Mines and an M.S. in Environmental Engineering from California Polytechnic State University.
