FERC. Condit's license was last reviewed in 1991, when it failed approval, and expired in 1993. From 1993 until 2011, PacifiCorp operated the plant under annual license extensions while it sought approval from FERC for the decommissioning. In December 2005, PacifiCorp filed an appeal of FERC's 1991 license rejection under the Bush administration's 2005 energy bill, which allows power producers to challenge licensing requirements retroactively. PacifiCorp explained the appeal as a backup plan in case decommissioning application failed. {| class="wikitable" |+ Specifications |- |FERC number | 2342 |- |Dam type | Gravity dam, long, high |- |Location | Mile 3.3 (km 5.3) |- |Concrete used for construction | 30,000 cubic yards (23,000 m³) |- |Floodgates | Five Tainter, two sluice, one hinged crest gate |- |Pipeline | dia, long, wood stave |- |Penstocks | 2 x dia x , steel and wood stave |- |Turbines | 2 x Francis |- |Tailrace | concrete lined, |- |Maximum generating capacity | 14.7 MW |- |Maximum turbine hydraulic capacity | 1400 ft³/s (40 m³/s) |- |Hydraulic head | |- |Operation modes | peaking or baseload, depending on available flow |- |Normal lake maximum elevation above SL | 295.2 |- |Reservoir capacity | |- |Useful reservoir storage capacity | |- |Surface area | |- |Average annual energy production (1936–1989) | 79,700 MWh |- |Annual operating costs | $400,000 |- |Annual power benefits | $2,896,000 |- |Annual value of power at consumer rates | $4.8 million ($0.06/kWh) |} Decommissioning FERC proposals After PacifiCorp's license application failed in 1993, FERC prepared an environmental impact statement that proposed installation of a state-of-the-art fish passage system as conditions for license renewal. The enhancements were to include fish ladders to allow upstream migrations of spawning salmon, and other modifications of the dam and operating procedures to allow a 95% survival rate of downstream migrating salmon. These conditions were based on National Marine Fisheries Service requirements. FERC's report also reviewed options to decommissioning the project, which it estimated would cost twice as much as the fish passage system. The investment needed to comply with the new requirements was estimated at $30 to $50 million, while at the same time reducing the amount of water available for power production. PacifiCorp decided the project was no longer economically viable, and began negotiations for decommissioning. In 1999, PacifiCorp announced an agreement had been reached, at which point they applied to FERC for approval.
