Technical provisions are avoidance and minimization measures used to protect fish life. WAC 220-660-100 through 220-660-450 are common technical provisions for typical hydraulic projects. All projects will also be reviewed relative to the provisions of WAC 220-660-080. The department will require technical provisions relevant to the individual proposal and the site characteristics. The department will also include special technical provisions to address project-specific and site-specific conditions not adequately mitigated by the common technical provisions. The department may apply saltwater provisions listed in WAC 220-660-310 through 220-660-450, in addition to any project-specific and site-specific technical provisions, to a project in tidally influenced areas upstream of river mouths and the mainstem Columbia River downstream of Bonneville Dam.
