Southern California Edison is asking state regulators not to reopen the settlement agreement over the closed San Onofre nuclear power plant, the Los Angeles Times reports. In a filing Thursday, the utility argued it would cause "serious harm to the public" if reopened. The California Public Utilities Commission approved a $4.7-billion settlement agreement last year. Consumer advocates turned against the settlement after it was revealed there had been unreported communication between members of the Public Utilities Commission regarding the shutdown of the plant.
