Care should be taken during transition periods close to the upper flow boundary to avoid frequent switching of priorities between spill and generation. Routine maintenance and testing. All units at all projects must undergo maintenance and associated testing. The testing necessitates deviation from the 1 percent peak efficiency band for periods of from 15 minutes to 8 hours. Scheduling of maintenance testing will be coordinated through the process outlined in B.4 above, to ensure that it is conducted during times of low fish passage within a day to minimize impacts on fish.
