PG&E: Tower had broken part

Company says it found damage, ‘wear’ on nearly 100-year-old piece of equipment

SAN FRANCISCO >> Pacific Gas and Electric has told state regulators that it found damage — a broken hook that supports high voltage wires — and “wear” on a nearly 100-year old transmissi­on tower where the devastatin­g Camp fire started in the early morning of Nov. 8.

“A suspension insulator supporting a transposit­ion jumper had separated from an arm on the tower,” PG&E said in a letter sent to the California Public Utilities Commission Tuesday night. A “C hook” used to support the insulator broke away and “wear was found at the connection point.”

PG&E previously notified the PUC that the transmissi­on tower, located high on a ridge along the North Fork of the Feather River, had malfunctio­ned about 15 minutes before the blaze

was first reported, but the utility’s latest filing provides details of why the equipment failed.

A lawyer suing the utility said the admission shows that a lack of proper maintenanc­e is to blame for the fire that killed 86 people, destroyed the town of Paradise and burned nearly 19,000 structures. It was the most destructiv­e blaze in state history.

“The only explanatio­n for why the equipment failed on the 100-year-old transmissi­on tower was that PG&E had not properly

inspected and maintained it to ensure that it was safe,” said Mike Danko, who is representi­ng more than 400 plaintiffs suing the utility in San Francisco.

Nearly 20 separate lawsuits have been filed over the fire, most in Butte County, with more expected.

Danko said the tower was designed to withstand the wind speed of about 50 mph reported around the time of the fire. In 2012, five towers to the west and on the same Caribou-Palermo transmissi­on line, collapsed during a winter storm with winds as high as 55 mph. Those towers were replaced in 2016.

“High voltage transmissi­on

lines, when properly inspected and maintained, are supposed to be able to easily withstand wind like we had on Nov. 8,” he said.

A PG&E spokespers­on said the utility would not comment beyond what was in the letter.

Cal Fire has not released a cause of the fire, but this news organizati­on reported last week that Cal Fire investigat­ors had homed in on the tower in a rugged area near the tiny town of Pulga and the Poe Dam in the Feather River Canyon, collecting parts of the structure — identified as :27/222 in the report — for evidence.

The letter, sent late Tuesday night by PG&E Senior

Director of Regulatory Relations Meredith Allen to Elizaveta Malashenko of the PUC’s Safety Enforcemen­t Division, said the utility assisted Cal Fire with the collection of evidence from the tower while PUC staff observed.

PG&E also reported to the PUC that it found slight damage to a neighborin­g tower where an anchor that held down an insulator had become disconnect­ed. Neither tower has been repaired and the lines they support remain out of service.

The letter also discussed an investigat­ion into a second ignition point on a rural road a few miles from Pulga near the Concow Reservoir,

where a tree apparently fell into a wooden electric pole, knocking it down. The area was badly burned with few trees left standing.

PG&E said it found that “the pole and other equipment was on the ground with bullets and bullet holes at the break point of the pole and on the equipment.”

It was not clear Wednesday how or if the bullet holes contribute­d to the pole’s collapse or how old they are.

A PG&E employee who first reached the area after the fire was out “observed several snapped trees, with some on top of the downed wires,” the letter said.

It was also a PG&E employee who first reported the fire to 911, the letter said.

The call came in at 6:25 a.m. from the Rock Creek Powerhouse facility, about 9 miles north of Poe Dam on Highway 70.

“Just got a report of a fire off Poe Dam on Highway 70,” the unidentifi­ed worker told an emergency dispatcher, according to a recording KTVU posted Wednesday. “Yeah, on the railroad tracks. Under the transmissi­on line.”

More calls quickly came in, with one man telling the dispatcher: “I just want to give you a heads up, the winds are really whipping.”
