Nuclear operators and regulators are continuing to pay close attention to theevents that have occurred at the Fukushima nuclear facility in Japan. PG&Eremains committed to operating safely and maintaining the trust and confidenceof its communities and customers. TheU.S. nuclear industry operates undersome of the most rigorous regulatory requirements of any industry in the country.

All nuclear plants in America are designed to withstand the most severeearthquakes and flooding that may plausibly occur at their location, based onhistorical records and exacting geologic assessments.

As the only utility in the country with a dedicated seismic research department,PG&E has long made earthquake safetyalong with all other safety issuesatop priority. Diablo Canyon was designed and constructed with seismic safety inmind and components of thefacility were tested to withstand probable groundmotions resulting from nearby faults. As part of PG&E's licenses to operate theplant, the utility has a Long Term Seismic Program which continually evaluatesseismic issues and applies new information to help assure that the facility isseismically safe. PG&E continuously partners with the United States Geological

Survey (USGS) to update the utility's understanding of earthquake hazards alongthe Central Coast and throughout the service area.Based on the latest available evidence, the Nuclear Regulatory Commission(NRC) has concluded that it is "highly unlikely that a similar combination ofevents such as those which occurred in Japan could occur in the United States,including at the Diablo Canyon (Power Plant)" and said it "does not believe theseismic hazards associated with the Diablo Canyon and San Onofre plants canbe directly compared to the events at Fukushima." (Please see attachment formore information.)Nonetheless, PG&E is undertaking state-of-the-art 3D seismic studies in the areaas part of its ongoing earthquake safety research. PG&E applied for funding forthese studies prior to the events in Fukushima. As part of its approval, theCalifornia Public Utilities Commission (CPUC) determined the studies will bereviewed by an independent peer review panel. Under an agreement with theNRC, PG&E will finish these important studies before final action is taken on thelicense renewal application.Extending Diablo Canyons operating license will save PG&E's customers billionsof dollars and provide reliable electricity needed to power the stateseconomy. Diablo Canyon powers more than 3 million homes in California,contributes more than $640 million each year to the San LuisObispo County economy and has operated safely for more than 25 years.For more specific information on the seismicity of the Diablo Canyon Power Plantarea, please see the below link to the Shoreline Fault Zone Report. http://www.pge.com/myhome/edusafety/systemworks/dcpp/shorelinereport/
