Klamath River Renewal Project California Environmental Quality Act (CEQA) and California and Oregon 401 Water Quality Certifications Technical Support Document

The primary objective of this Technical Support Document is to provide the California State Water Resources Control Board (SWRCB) and the Oregon Department of Environmental Quality (ODEQ) the information they require to prepare the Clean Water Act Section 401 Water Quality Certifications (401 Certifications) for the Lower Klamath Project, also referred to as the Klamath River Renewal Project (Project). The 401 Certifications are required before the Federal Energy Regulatory Committee (FERC) can issue a final surrender order for the Project. In addition, this document provides the latest available technical and field information developed by the Klamath River Renewal Corporation and its consultants (KRRC), for SWRCB’s use in preparation of an Environmental Impact Report (EIR) consistent with the California Environmental Protection Act (CEQA). The SWRCB and ODEQ communicated their specific information needs via letters dated August 24, 2017 and July 19, 2017, respectively. Copies of the Additional Information Request letters can be found in Appendix A.
