Brilliant Powerplant Expansion Project – Fish and Habitat Mitigation and Compensation Plan
Author: Brilliant Expansion Power Corporation
This document provides an introduction to the Brilliant Dam Expansion Project, followed by detailed information on project construction (including mitigation and monitoring plans) and project operations (e.g., load factoring, minimum flows, reduced tailwater levels).
See summary sections in report (Sections 2.6 and 3.6)
Reflecting the general and specific mitigative design measures identified in this Plan, no long term negative effects to fish and fish habitats are expected as a result of project construction activities. Notwithstanding the best efforts of the Owner and the Contractor to eliminate all construction effects, some temporary minor negative effects to aquatic environments will occur during construction. These are expected to be offset in the long term by habitat enhancement features (i.e., the crenulations and the new tailrace eddy) that have been incorporated into the design of the tailrace excavation.
The committed operations and management measures, procedures, and prescriptions will serve, with one exception, to eliminate the risk of detrimental long-term effects on fish or fish habitat and will provide long-term benefits as described. The exception is the potential mortality of fish entrained through the new BEP turbine. For the reasons provided in the PAC and agreed to by the agencies, this impact cannot be mitigated and will result in a long-term residual negative project effect.
