Construction of the Final Groundwater Remedy

Phase 1 Construction Project Initiation Meeting held October 2, 2018

A Phase 1 Construction initiation meeting was held on October 2, 2018, in Needles, California. Over eighty individuals participated in the initiation meeting, including representatives from DOI, DTSC, the U.S. Fish and Wildlife Service, Native American Indian Tribes (Fort Mojave Indian Tribes, Chemehuevi Tribe, Cocopah Indian Tribe, and the Colorado River Indian Tribes), and key construction contractors involved in the initial construction activities. The initiation meeting covered initial construction activities and schedules, PG&E’s health & safety expectations, DOI’s and DTSC’s expectations, and perspectives of the Tribes.
