Federal regulators dismissed a complaint against Southern California Edison that accused the utility of failing to seek approval for changes to the San Onofre nuclear power plant that ultimately led to the facility’s permanent closure.
In a July 28 letter, the Nuclear Regulatory Commission said that because the plant is no longer in operation, the complaint filed by the environmental group Friends of the Earth does not need further consideration.
Friends of the Earth had claimed that Edison failed to request a license amendment for changes to the new but faulty steam generators. A small radiation leak in one of the steam generators led the utility to shut down the facility in January 2012.
