This Draft Environmental Assessment and Initial Study (Draft EA/IS) for the proposed Trinity River Sediment and Wood Augmentation Project (Augmentation Project, Project, or Proposed Action) has been prepared by the U.S. Department of the Interior (DOI), Bureau of Reclamation (Reclamation), and Trinity River Restoration Program (TRRP, Program) to meet the requirements of the National Environmental Policy Act (NEPA) and California Environmental Quality Act (CEQA). An EA provides coverage for NEPA, and IS provides coverage for CEQA. The North Coast Regional Water Quality Control Board (Regional Water Board) will act as the project CEQA lead. Reclamation’s TRRP is the lead agency under NEPA and the Cooperating Agency is Bureau of Land Management’s (BLM) Redding Field Office. The primary objective of the Augmentation Project is to enhance river conditions for salmon and steelhead, including federal- and state-listed species and stocks, by creating more spawning and rearing habitat in the mainstem Trinity River. This objective is met through the placement of sediment and wood into the river at strategic locations. The federal agencies worked with the Regional Water Board to analyze the potential impacts of the proposed activities under NEPA (40 Code of Federal Regulations [CFR], Section 1508.9(a)), and CEQA (California Public Resources Code Sections 21000 et seq.).
