NOW AVAILABLE: Draft EA-IS for Sites Reservoir now available for public comment **Document description clarified**

From the Bureau of Reclamation:

The Bureau of Reclamation (Reclamation), as the Lead Agency pursuant to the National Environmental Policy Act (NEPA) and the Sites Project Authority (Authority), as the Lead Agency pursuant to the California Environmental Quality Act (CEQA) have prepared an Environmental Assessment/Initial Study (EA/IS) for the 2022-2024 Sites Reservoir Geologic, Geophysical, and Geotechnical Investigations.

Reclamation and the Authority are proposing to conduct geologic, geophysical, and geotechnical investigations in Glenn, Colusa, and Yolo Counties.  The purpose of the activity is to conduct field investigations and surveys to obtain data and information needed to formulate and refine the engineering design and to assist in the preparation of permit applications for the proposed Sites Reservoir and associated facilities in western Sacramento Valley. The investigations include up to 70 pavement cores, 258 augers and borings, and 33 cone penetration tests at varying depths. In addition, approximately 70 piezometers would be installed at select auger or boring locations. Non-invasive geophysical surveys would occur at each investigation location.  Non-invasive geologic surveys would also occur at various locations in the proposed Project Area.

A Proposed Mitigated Negative Declaration for the investigations is also available on the Sites Project Authority’s website at sitesproject.org/environmental-review.

Public comment period extends through June 21, 2022.
