Our cameras were allowed into the hot zone 24 hours after a PG&E pipe exploded destroying many lives and homes.
The California Public Utilities Commission announced Sunday it's ordered Pacific Gas and Electric to inspect its entire natural gas system. The order is a direct result of the deadly explosion in San Bruno Thursday night that killed at least four people and injured dozens of others.
The ordered inspections came on the same day hundreds of San Bruno residents were allowed back into their homes. In call, 315 houses were given the green light to be reoccupied following detailed structural inspections.
The order was made to ensure the integrity of PG&E's natural gas pipeline system, according to a press release from the CPUC. The CPUC is a state agency that covers not just the Bay Area, but the entire state.
CPUC President Michael Peevey said in the Sunday afternoon release he wanted to assure residents that immediate action will be taken. "We will direct PG&E to immediately begin an inspection of its natural gas transmission system, as well as to take other immediate actions to ensure safety and to assist in our investigation,” Peevey said.
Other than using the word "immediate" in the release, no timeline of the inspections was given.
Specific directions to PG&E:
Thursday's explosion created a crater 167 feet long and 26 feet wide, according to NTSB Vice Chairman Christopher Hart. "This really emphasizes the magnitude of what occurred here," Hart said.
Concern about whether similar pipes are under their homes had Bay Area residents flocking to websites that list such things.
The pipe that exploded was a "Class 3." Class 3 pipes are in areas with more than 47 homes per linear mile of pipe within 220 yards on either side of the pipeline.
The gas inside was odorized to make it detectable. People in the area have told reporters they smelled gas in the days and weeks prior to Thursday. But PG&E officials have said so far they haven't been able to find any reports to verify that.
On Friday, the CPUC established a toll-free number and an email address for anyone who has information on a natural gas smell in the San Bruno area in the weeks prior to the explosion and fire. The number is 800-789-0550 and the email address is SBFire@cpuc.ca.gov.
The specific section of gas pipeline that ruptured was ranked as high-risk because it ran through a highly populated area.
The Associated Press obtained documents that showed that PG&E submitted paperwork to regulators that said a section of the same gas line, but about two and half miles from the blast site, was within "the top 100 highest risk line sections" in the utility's service territory.
The 30-inch pipe was installed in 1948 and was slated to be swapped for new 24-inch pipe. That project never happened.
Thursday's explosion launched a 28-foot underground pipe about 100 feet into the air and onto the street.
His team is already at work. but we won't know for months what they found. The NTSB said he estimates it would be 14 to 18 months before they issue the final report and recommendations. Chhatre and team will be the only source of information about the investigation. The NTSB has instructed PG&E, the Pipeline and Hazardous Materials Safety Management Administration, the California Public Utilities Commission and other organizations to not entertain requests from media.
