PG&E Fulfills Two Additional NTSB Recommendations By Further Enhancing
Pipeline Integrity Management Program
CPUC Safety and Enforcement Division Also Confirms Safety of Gas Transmission
Line 147 in San Carlos
SAN FRANCISCO, Nov. 18, 2013
SAN FRANCISCO, Nov. 18, 2013 /PRNewswire/ -- The National Transportation and
Safety Board (NTSB) has notified Pacific Gas and Electric Company (PG&E) that
the utility has fulfilled two additional safety recommendations in response to
the 2010 pipeline accident in San Bruno. The two completed actions are:
oIntegrity Management Program: PG&E reviewed every aspect of its
Transmission Integrity Management Program (TIMP) and implemented a revised
program to better evaluate and address threats to its natural gas pipeline
system. As part of this effort, the company updated the model and risk
methodology that considers all defect and leak data for the life of each
pipeline, and an improved self-assessment process. Based on the new
integrity management enhancements, PG&E conducted a revised threat
assessment with a methodology that incorporates additional data on
high-consequence, populated areas. A copy of the assessment was submitted
to the California Public Utilities Commission (CPUC) and the Pipeline and
Hazardous Materials Safety Administration. PG&E's TIMP is a comprehensive
program for assessing and managing the integrity of gas transmission
pipelines and taking appropriate action to address any risks.
oThreat Assessment: PG&E has completed a threat assessment review of its
gas transmission system using the revised methodology established in its
TIMP. PG&E uses threat assessment and identification to assess and rank
the risks associated with gas pipes located throughout the transmission
PG&E has now fulfilled nine of the 12 total actions recommended by the NTSB.
Of the three remaining safety recommendations, the NTSB considers PG&E's
progress "open-acceptable response," which means acceptable pending
"We continue to make real, measurable progress as we strive to become the
safest and most reliable gas operator in the nation," said Nick Stavropoulos,
executive vice president of PG&E's gas operations. "We are pleased to have
completed nine out of 12 NTSB recommendations, but there is still more work to
be done. We are focused on fulfilling the remaining three recommendations, as
well as doing much more beyond these steps to improve our gas system."
The seven previously completed NTSB recommendations are MAOP validation, work
clearance procedures, public awareness plan, records, emergency procedures,
9-1-1 notification and toxicology tests.
Additionally, the company has received concurrence from the CPUC Safety and
Enforcement Division that Line 147 in San Carlos is safe to operate.
Separately from the NTSB recommendation close-outs, the CPUC Safety and
Enforcement Division (SED) provided concurrence in a November 14 report that
gas transmission line 147, which is located in the city of San Carlos, can
safely operate at a Maximum Operating Pressure (MOP) of 330 pounds per square
"We are pleased that the Safety and Enforcement Division agrees with us that
Line 147 is safe to operate," said Sumeet Singh, senior director of integrity
management for PG&E's gas operations. "This is an important step to make sure
we're continuing to serve our Peninsula customers with safe and reliable gas
