The Project is located on a combination of lands administered by BLM and the California State Lands Commission (CSLC), as well as lands on the Ewiiaapaayp Indian Reservation and some private parcels. The BLM is the lead agency for complying with the National Environmental Policy Act (NEPA); the California Public Utilities Commission (CPUC) is the lead agency for complying with the California Environmental Quality Act (CEQA) for the Environmental Impact Review.

PanGIS is provided professional archaeologists for full-time environmental compliance services during all ground disturbance, all construction activities near ESAs, and in other areas determined appropriate for full-time monitoring. The archaeological monitors are qualified archaeologists who are familiar with the types of historical and prehistoric resources that could be present in the Project and were directly supervised by principal archaeologists. All monitors were required to complete an electronic daily monitoring log.  PanGIS staff were also responsible for maintaining the geospatial data for the Project, which is updated daily on tablets used by all field archaeologists. Tablets are loaded with Arc Collector which allow staff to record, map and safeguard cultural resources.
