On April 9, Senate Environment and Public Works Chairman Barbara Boxer (D-CA) and Rep. Ed Markey (D-MA) sent a letter to Nuclear Regulatory Commission (NRC) Chairman Allison Macfarlane on the San Onofre nuclear facility. The letter urged the NRC to complete its investigation on the installation of faulty steam generators, to not take any action that could lead to restarting of the facility before the review is complete, and to include a public comment section in the investigation. The members also opposed a proposal by Southern California Edison to shortcut the license amendment process by declaring that operations at 70 percent would not involve significant risks.
