Common use of Introduction and Overview Clause in Contracts

Introduction and Overview. On February 18, 2010, the United States, the States of California and Oregon, PacifiCorp, Indian tribes, and a number of other stakeholders signed the Klamath Hydroelectric Settlement Agreement (KHSA). The original KHSA was subsequently amended and signed in April and November 2016; the amendments did not affect the interim measures. The amended KHSA lays out the process for transferring ownership of PacifiCorp’s Klamath Hydroelectric Project to an independent dam removal entity (DRE) and then eventual decommissioning and removal of four dams on the Klamath River (i.e., X.X. Xxxxx, Copco 1, Copco 2, and Iron Gate dams) by the DRE following approvals from the Federal Energy Regulatory Commission. The KHSA includes provisions and detailed actions for the interim operation of the dams and mitigation activities prior to removal of the dams or the termination of KHSA. One of these measures titled: Interim Measure 15 - Water Quality Monitoring states that PacifiCorp shall fund ($500,000 per year) long-term baseline water quality monitoring to support water quality improvement activities, dam removal studies, permitting studies (as necessary), and form a long-term record to assess trends and other potential changes in the basin. This includes funding for blue-green algae (cyanobacteria) and cyanobacteria toxin monitoring, to protect public health. This plan addresses the eleventh year of monitoring under Interim Measure 15 (hereafter referred to as IM 15). Since the goals and objectives of IM 15 remain the same and the sampling entities and locations are basically unchanged since monitoring began in 20091, this document provides a brief summary of the of IM 15 goals and objectives, sampling strategies, and any updates and/or changes to the sampling from previous plans. Detailed discussions on goals, objectives and the rationale for the parameters sampled can be found in the previous study plans, available on the Klamath Basin Monitoring Program (KBMP) website (xxxx://xxx.xxxx.xxx under the Collaboration tab on the Home page). This website hosts all of the IM 15 study plans and results. These study plans are also available on the PacifiCorp Klamath Hydroelectric Project website (xxxx://xxx.xxxxxxxxxx.xxx/es/hydro/hl/kr.html). This study plan outlines the parameters to be sampled, their frequency and location by sampling entity for the monitoring period from February through December 2019. The IM 15 monitoring includes monitoring of the Klamath River mainstem (including reservoirs) from Upper Klamath Lake downstream through the estuary (Figure 1). The long-term baseline water quality monitoring includes 22 monitoring sites that have been sampled under this planning process since 2009. Two baseline sites near X.X. Xxxxx reservoir were dropped from sampling in 2017 (see Section 5.2.3). The cyanobacteria and toxin monitoring includes 18 monitoring sites. Site coordinates for all sites regardless of program are presented in Appendix A. The water quality parameters, locations, sampling frequency, and sampling methods for the 2019 IM 15 program represents consensus amongst the following participants: PacifiCorp, North Coast Regional Water Quality Control Board (NCRWQCB), Oregon 1 Note that in 2009, sampling was done under an interim settlement agreement. Department of Environmental Quality (ODEQ), Karuk Tribe, Yurok Tribe, U.S. Bureau of Reclamation (BOR), and the United States Environmental Protection Agency, Region 9 (EPA).

Introduction and Overview. On February 18, 2010, the United States, the States of California and Oregon, PacifiCorp, Indian Native American tribes, and a number of other stakeholders signed the Klamath Hydroelectric Settlement Agreement (KHSA). The original KHSA was subsequently amended and signed in April and November 2016; the amendments did not affect the interim measures. The amended KHSA lays out the process for transferring ownership of PacifiCorp’s Klamath Hydroelectric Project to an independent dam removal entity (DRE) and then eventual decommissioning and removal of four dams on the Klamath River (i.e., X.X. Xxxxx, Copco 1, Copco 2, and Iron Gate dams) by the DRE following approvals from the Federal Energy Regulatory CommissionCommission (FERC). In November 2022, FERC issued a surrender order for the Lower Klamath Project. On December 1, 2022, the Klamath River Renewal Corporation (KRRC, the DRE), California, and Oregon became co-licensees for the Lower Klamath Project. The property was transferred concurrently with the license. This transfer started the actual dam removal process envisioned in the amended KHSA. Starting in early spring 2023, there will be an extensive amount of work on the Lower Klamath project in advance of reservoir drawdown and dam removal scheduled to take place in 2024. The KHSA includes provisions and detailed actions for the interim operation of the dams and mitigation activities prior to removal of the dams or the termination of KHSA. One of these measures titled: Interim Measure 15 - Water Quality Monitoring states that PacifiCorp shall fund ($500,000 per year) long-term baseline water quality monitoring to support water quality improvement activities, dam removal studies, permitting studies (as necessary), and form a long-term record to assess trends and other potential changes in the basin. This includes funding for blue-green algae (cyanobacteria) and cyanobacteria toxin monitoring, to protect public health. This plan addresses the eleventh fourteenth and final year of monitoring under Interim Measure 15 (hereafter referred to as IM 15). Since the goals and objectives of IM 15 remain the same and the sampling entities and locations are basically unchanged since monitoring began in 20091, this document provides a brief summary of the of IM 15 goals and objectives, sampling strategies, and any updates and/or changes to the sampling from previous plans. Detailed discussions on goals, objectives and the rationale for the parameters sampled can be found in the previous study plans, available on the Klamath Basin Monitoring Program (KBMP) website (xxxx://xxx.xxxx.xxx under the Collaboration tab on the Home page).

This study plan outlines the parameters to be sampled, their frequency and location by sampling entity for the monitoring period from February April through December 20192023. The IM 15 monitoring program includes monitoring of the Klamath River mainstem (including reservoirs) from Upper Klamath Lake downstream through the estuary (Figure 1).
