San Bruno politicians and others called for a halt to non-public negotiations held over the last month between Pacific Gas & Electric and victims of the September 2010 natural gas blast in San Bruno. They were joined this week by the Utility Reform Network and backed by the city councils of San Bruno and San Francisco. They are urging the removal of the appointed negotiator for the settlement talks. On Oct. 24, the San Bruno City Council called for California Public Utilities Commission president Mike Peevey to resign. The leader of the negotiations, former U.S. Sen. George Mitchell, \u201crepresents a large insurance carrier that potentially may be required to pay costs incurred by PG&E related to the San Bruno explosion,\u201d alleged The Utility Reform Network. The organization and the cities of San Bruno and San Francisco contend that because of that connection, Mitchell should not be involved in the negotiation details. Public hearings at the California Public Utilities Commission on the settlements for affected parties were placed on hold this month.
