SAN FRANCISCO (AP) — California utility regulators say they found no problems after investigating complaints from welders who claimed welds on Pacific Gas & Electric Co.'s pipelines had not been properly inspected.
The California Public Utilities Commission on Wednesday said staff thoroughly investigated reports from two welders with the United Association of Plumbers, Pipe Fitters and Steamfitters, who raised the concerns after working on tests of PG&E pipelines in 2011.
CPUC's Consumer Protection and Safety Division said they found no instances in which welds were not inspected in compliance with state and federal laws. Regulators concluded PG&E is evaluating defects when they are found.
A Sept. 9, 2010 explosion on a PG&E transmission line killed eight people and destroyed 38 homes in the San Francisco suburb of San Bruno.
