Federal regulators are auditing the California Public Utilities Commission\u2019s compliance with natural gas pipeline safety regulations. \u201cWe look forward to assuring the [Pipeline & Hazardous Materials Safety Administration] that the CPUC handles its responsibilities with integrity and lawfulness, and that our enforcement cases against PG&E are well underway, with an amended staff recommendation,\u201d said Terrie Prosper commission spokesperson. She noted that the ongoing audit is a routine annual review by the federal agency. The City of San Bruno, the site of a Pacific Gas & Electric pipe blast in September 2010, welcomed the review. It also touted the Pipeline & Hazardous Materials agency\u2019s July 19 letter telling San Bruno it takes its pipeline safety concerns \u201cvery seriously.\u201d It continued, \u201cWhen the audit report is finalized and we have reviewed [CPUC] president Peevey's response, PHMSA will determine whether further actions or proceedings should be taken in this matter.\u201d San Bruno Mayor Jim Ruane said he was \u201chopeful about this first step to improving the State\u2019s ability to regulate pipeline infrastructure and create a new regulatory model for California.\u201d San Bruno also has been pushing for a more stringent penalty on PG&E by the CPUC. Last week, the commission\u2019s Consumer Safety & Protection Division filed a revised $2.25 billion penalty proposal, under which all of the money would come from shareholders and utility equity (Current, July 19, 2013).
