RECOMMENDED CORRECTIVE ACTIONDevelop or revise existingprocedures to require posit ive verification of he expected systemstatus and configuration when working on a pipeline. These procedures shouldemphasize that plat maps should not be considered as-builts and are not to be usedin lieu o fother means o positive verification. Develop or revise existing procedures to require, as part of the design process, furtherinvestigation (e.g., field verification) of the system configuration when estimating a jobfor which as-builts are not available.

With this event in mind, review the current process for receiving, approving and storingjob folders, including as-builts, to assure that all job folders will be adequately filedand the necessary mapping changes made in a t imely manner. Develop and implement a process for a more detailed pre-job briefing, including adiscussion of what can go wrong and who is responsible for taking what action i it doesgo wrong, and ensuring that the appropriate equipment is available to handle potentialemergencies.

Mr. Sipe provided additional information after the presentation: The speed of the gas was not measured in the report. Sewer traps near the home could have dried out and gas may have entered through the toiletor sink mixing with air and accumulating at ceiling. f the gas encountered ignition source, you would expect a flame to propagate thru themixture and explode. The stove had a continuous pilot flame and could have been the ignition source.Mayor Burnett noted that PG&E is will provide another iteration of the report.Council members provided questions and comments regarding this report: Why were the following items not in the report: 14 individuals indicated they had knowledge but were not interviewed The City of Carmel was not included in the report. Why? Why was the City notified 39 minutes after the incident? The City could have provided an evacuation if they were notified sooner. There are serious items missing in this report regarding response time and communicationprotocol.Dennis Lee, Senior Utilities Engineer of the Public Utilities Commission, provided apresentation regarding their investigation, the timeline, and stated that there will be theopportunity for residents and council members to provide input to the Public UtilitiesCommission. He noted the following: We are looking at issues including response time, when the welders found the leak, and othertimeline items. A complete report will be provided by the end of summer 2014. You will have the opportunity to weigh in. Once the report is finalized it with either goes through a citation process or a formalproceeding.

Mayor Burnett opened the meeting to public comment at 4:23 PM Lucas Austin: Once they addressed the pressure in the pipe, what was pressure before thetapping? Regarding the timeline, they called the supervisor at 11: 6 AM and called 9 at

11:17 am. Why did they not call 9 first?Mayor Burnett closed public comment at 4:25 PMMr. Sipes: PG E stated that the pressure was not checked until the pipe was tapped, so they donot know the pressure prior to this.Mayor Burnett reopened public comment at 4: 8PM Judy Me McCullough, resident: My daughter was home and we were in the house when theincident happened. Why did we not receive evacuation orders? I now have a four inch PG Epipe with no meter on it. Did they perform an investigation before they did my pipes?

It is important to have trained PG E supervisors.Mayor Burnett closed public comment at 4:3 PMMayor Burnett noted this opportunity for Council members to provide additional questions thatmay e answered in the revised report.

with what happened above ground.o Are there shut off valves in the City? Are they by block, or what? Can they einstalled:o The plat map did not show relationship between sewer line and and the gas line.o Why did the video not give us this information? Councilmember Talmageo PG E needs to understand the community is concerned today when they see aPG E truck on their blocko When will we have as-built maps? We need assurance that you k now what isunderground.

Mayor Burnetto I would like regular monthly reports detailing response times, going forward.o Carmel residents and the Police Department were not interviewed.o We are more interested in following people, not molecules.o I was told y several residents that they smelled gas during that timeline.o The timeline needs to e explained- what went wrong? Why was 9 not calledearlier? n that 37 minutes they could have protected the public, they need to becalled immediately.PG E Issues:o Legal issues - what is the local law, and has that been met? I recommend thatPG E does that analysis.o Business practices - what is wrong with the PG E culture, we've had otherissues. There were steps along the way, other minds who decide not to call 911. Iadvise getting an outside firm to conduct an analysis of this issue.
