Chief Miguel stated that this gives a sense of all of the things that go into developing this risk analysis. He added that he believes it is important to note that because of this report and the attention paid to the report, PG&E has been in the Fremont, Pleasanton, and Livermore areas evaluating this infamous Line 107 to see if any problems can be identified. He noted that it will take some time before the assessment will be completed. Chief Miguel then introduced Deputy Fire Chief Joe Rodondi to display where the pipes run and to answer any questions about the transmission lines. Deputy Fire Chief Joseph Rodondi indicated that the PG&E report to the PUC talks about a $35 million improvement for an eight-mile segment of Line 107, which, according to the report, has the highest risk. He stated that this 500-psi line runs from the east to the southeast, just south of the Lawrence Livermore Laboratory, south of Mines Road, past Tesla Road, then turns south on Isabel Avenue extension by Pigeon Pass, and up over to Sunol.He added that there is another 500-psi line (Line 131) that runs north to south on the Isabel Breezeway. He noted that a segment of Line 131 was moved when Ruby Hill was built to skirt the development. He stated that this new section runs by the Isabel Bypass and skirts the perimeter past the east gate, which goes up and over Pigeon Pass into Sunol. Deputy Fire Chief Rodondi stated that there are two 200-psi transmission lines that come off of Line 131: one that runs on Isabel Expressway and down Stanley Boulevard into Pleasanton; and the second running east to west down the I-580 corridor. Commissioner Blank thanked both Fire Chief Miguel and Deputy Fire Chief Rodondi for their attendance and presentation. He then inquired if the 30-inch high pressure pipeline comes within 100 feet of certain homes in the Ruby Hill area. Deputy Fire Chief Rodondi replied that Line 131 skirts the perimeter property along the fence line of East Ruby Hill Boulevard, about 150 feet from some homes on East Ruby Hill Boulevard. Commissioner Blank stated that he understands, from the National Department of Transportation website, that there is a high pressure jet fuel line and an unleaded fuel line in Pleasanton. He recalled that a few years back, someone dug into an unleaded gas or jet fuel line in Concord. He inquired if steps were being taken to ensure these pipes are reviewed as they could be 50 years old. Deputy Fire Chief Rodondi said Kinder Morgan is the company that owns and operates the petroleum line that goes through Pleasanton. He noted that this was the same pipeline that was involved in the Contra Costa incident caused by a backhoe operator and welder which ignited some residual fuel in the line. He indicated that the line runs down the Iron Horse Trail and just on the other side of Pleasanton Garbage Service at the intersection of Busch Road and Valley Avenue, heads towards Stanley Boulevard, then south on Stanley Boulevard and west on Stanley Boulevard all the way out to the I-580 corridor, and finally heads south down to Milpitas.
