Roberto Delgado and his wife were praying the rosary on the night of Jan. 7 when they heard two loud booms that shook their Sylmar home. Then came a flash of light so bright that in the dead of night they could briefly see out their window the rocks and gullies of the San Gabriel foothills behind their house.

Seconds later, Delgado said in an interview, the couple saw flames under two electric transmission towers owned by Southern California Edison — even more shocking because they had seen a fire ignite under one of those towers just six years before.

“We were traumatized,” he said. “It was almost the exact same thing.” In both fires, the family was forced to race to their car and flee with few belongings as the flames rushed through the brush toward their home, which survived both blazes.

Edison’s maintenance of its power lines is now under scrutiny in the wake of January’s devastating Eaton fire, which destroyed a wide swath of Altadena and killed 19 people. Video captured by eyewitnesses shows the Eaton fire igniting under Edison transmission towers.

A lawsuit making its way through Los Angeles County Superior Court is raising new questions about Edison’s role in the 2019 Saddle Ridge fire in Sylmar and whether the company was transparent about the cause of the blaze. The fire killed at least one person and destroyed or damaged more than 100 homes and other structures. Firefighters were able to contain the more recent Sylmar fire, called Hurst, before any homes were destroyed.

The lawyers contend that both fires were caused by the same problem: an improperly grounded transmission line running through the foothills of Sylmar that Edison failed to fix, which the company denies.

In a court filing, the lawyers included a deposition they took of an L.A. Fire Department captain who said he believed that Edison was “deceptive” for not informing the department that its equipment failed just minutes before the 2019 blaze ignited, and for having an employee offer to buy key surveillance video from that night from a business next to one of its towers.

Edison has flatly disputed the lawyers’ assertions, calling their claims about the 2019 fire an “exotic ignition theory” based on “an unproven narrative.”

Kathleen Dunleavy, a spokeswoman for Edison, said that the utility had complied with the requests of investigators looking into the two fires and that “there is no connection” between the incidents.

Dunleavy said Edison did not tell the fire department about the failure of its equipment in 2019 because it happened at a tower miles away from where the fire ignited. And she said it is common for any investigator to seek to obtain video that could aid in an investigation. “SCE’s investigator did not offer to buy surveillance video,” she said.

“We follow the law. Period,” she said.

Dunleavy said the company has completed tests that show the transmission line is safe. She declined to share the results and pointed to testimony by Edison’s expert in the case — Don Russell, a Texas A&M professor of electrical engineering — who said the line was properly grounded.

As for the Jan. 7 Hurst fire, the utility told regulators in a February letter that it believes its equipment “may be associated with the ignition” of the blaze. The letter said the company found two conductors on the ground under a Sylmar tower. The repairs, the letter said, included replacing equipment at several towers and more than three miles of cable.

Delgado and Perez say that on the night of the fire they heard two loud booms and a flash of light so bright they could briefly see out their window the rocks and gullies of the San Gabriel foothills.

Undergrounding of towers questioned

In dispute is whether the failure of steel equipment at the top of an Edison transmission tower on the night of Oct. 10, 2019, caused a massive power surge across the system, resulting in multiple towers becoming electrified and intensely hot.

The tower, where the steel part known as a y-clevis broke, sits just off the 210 freeway in Sylmar on land shared with a nursery. The Edison tower behind Delgado’s home where investigators say the 2019 fire ignited is more than two miles away from the nursery.

The attorneys said in court filing that Edison made a “cost-saving choice” when building the transmission line in 1970 to not include “any purposeful grounding devices” that would enable power surges to dissipate down the tower and into the earth. Instead, the company used “only insufficient concrete footings,” the lawyers said in their filing.

Mark Felling, an electrical engineer and paid expert in the case, testified that he found that the size of the cement footings under the towers along the line varied by a factor of 10. The size of the footings, he said,affects whether the tower is properly grounded.

Felling said he believed that a sudden power surge could cause some towers to become “electrified and potentially very hazardous.”

Edison has disputed that theory and said in court that the electrical surge caused by the failure of equipment at the tower by the nursery safely dispersed. The utility said it was scientifically impossible that the electrical surge caused a fire 2½ miles away.

“The undisputed material facts cannot support plaintiff’s theory that SCE caused the Saddleridge fire,” the company wrote in a motion this month, which asked the judge to dismiss the case. A hearing on the motion is scheduled for Oct. 6.

Edison’s motion included a copy of the L.A. Fire Department’s investigation, which included new details of how the company responded to fire investigators days after the 2019 fire.

Delgado said his rosary and prayers were important to surviving the fires.

Failure to report power surge

L.A. Fire investigator Robert Price arrived at the dirt road leading up to the hillside transmission line where the fire had ignited the night before to see the yellow crime scene tape lying on the ground and an Edison truck driving out, Price said in his report.

Price also wrote that Edison’s equipment recorded a fault that resulted in a surge of electricity about three minutes before Delgado reported the fire to 911 at 9 p.m. But the company did not tell the Fire Department about the fault, Price wrote.

Instead, L.A. Fire Capt. Timothy Halloran learned from a news report that Sylmar resident Jack Carpenter had recorded a large flash of light on his dashboard camera at 8:57 that night as he was traveling west on the 210 freeway.

Halloran traced the flash to a transmission tower built on land used by Ornelas Wood Recovery Nursery. Halloran interviewed employees at the nursery, who told him that an Edison employee had offered to buy the surveillance footage from the nursery’s camera, according to a deposition Halloran later provided to lawyers representing the victims.

A nursery employee also had taken photos of the broken steel equipment he found at the foot of the tower, according to Price’s report. The employee told Halloran that an Edison crew came the day after the fire and cleaned up the shattered pieces.

Halloran said in the deposition, according to a June court filing, that the company’s failure to report the fault and its offer to buy the nursery’s surveillance video made him believe that the company’s actions were “deceptive.”

Price said in his report that he also saw Edison crews cleaning the towers along the line three days after the fire’s start. An Edison employee told him that the utility cleans the towers once a year but had decided to clean them that day “because they were dirty from the smoke and fire,” Price wrote.

The cleaning did not prevent fire investigators from finding burn marks at the bottom of a second tower not far from where Delgado and his wife live, which Price said may be related to the “catastrophic failure” of equipment at the tower by the nursery.

In his final conclusion on the fire, Price wrote that it was “outside my expertise” to determine whether the failure of equipment at the tower above the nursery “could cause high voltage to travel back through the conductors … and cause a fire, possibly through the tower’s grounding system” more than two miles away.

“Therefore the cause will be undetermined,” Price wrote.

Dunleavy said that Edison had notified the California Public Utilities Commission about the fire before it began cleaning up the broken pieces of equipment found under the tower at the nursery. That cleanup and the company’s repairs, Dunleavy said, were needed to “ensure safety and reliability” of the line.

She added that it was common practice for utilities to wash down equipment after a fire before the system was reenergized.

According to an L.A. Fire investigator, Edison’s equipment recorded a fault that resulted in a surge of electricity about three minutes before Delgado reported the fire to 911 at 9 p.m.

State utility investigators find violations

Also investigating the 2019 fire in the days after its start was Eric Ujiiye at the Public Utilities Commission.

The commission’s safety staff investigates fires that may have been caused by electric lines to determine whether the utility violated safety regulations.

Ujiiye said in his report that he found that Edison violated five regulations, including failing to safely maintain its equipment at the tower by the nursery.

Even though Price’s investigation for the L.A. Fire Department stated that the cause is undetermined, Ujiiye said in his report that he believed that the failure of equipment at the tower by the nursery “could have led to a fire ignition” at the pylon more than two miles away.

The commission’s staff asked Edison to perform tests to show that the towers on the line were properly grounded. According to a written response from Edison, the utility objected to the request as “vague and ambiguous.” But the company agreed to do the tests, which would be observed by the commission inspectors.

Terrie Prosper, a spokeswoman for the commission, said that the agency’s staff was planning to meet with Edison at the transmission line to witness the tests. However, COVID-19 pandemic restrictions delayed that meeting and the requested undergrounding tests. She said that commission staff later learned that Edison had performed similar tests soon after the fire. Those test results “sufficed,” Prosper said, and the company “was not made to re-do the tests.”

Prosper said the commission did not fine or otherwise penalize Edison for the five violations because the LAFD report said the cause was undetermined. She said company had corrected the violations.

April Maurath Sommer, executive director of the Wild Tree Foundation, which has challenged Edison’s requests to have utility customers pay for fire damages, questioned the commission’s handling of the 2019 fire.

“You would think that the Public Utilities Commission would use fines to address really egregious behavior in the hope it would deter future behavior that causes catastrophic fires,” she said.

Maurath Sommer noted that Edison has been repeatedly found to have failed to cooperate with investigators looking into the cause of devastating fires. For example, commission investigators said in a report that the utility refused to provide photos and other details of what its employees found at the site where the Woolsey fire ignited in 2018. The Edison crew was the first to arrive at the scene of the fire that destroyed hundreds of homes in Malibu. Edison argued that the evidence was protected by attorney-client privilege.

Edison’s Dunleavy said the allegation by commission investigators was later resolved. “We take our obligation to cooperate with the CPUC seriously,” she said.

Prosper of the commission said, “Public safety is, and will remain, our top priority,”

Another fire in Sylmar

At about 10:30 on the night of Jan. 7, Katherine Twohy heard a loud crack and saw a bright flash. Edison’s transmission towers in Sylmar skirt around the edge of the Oakridge Mobile Home Park, where Twohy, a retired psychologist, lives.

“I was just coming in my back door and there was just this incredible flashing of white lights,” Twohy said. “Incredibly blue-white lights.”

She walked to her living room window where she can see two Edison towers, which are separated by more than a hundred yards. Twohy said she could see flames at the base of each one.

“The fires had made little circles around the base,” she said.

Twohy said she saw flames under the same towers the night the Saddle Ridge fire ignited in 2019.

“I thought, ‘Oh my god, it’s just like last time,’” Twohy said.

In court, lawyers representing victims of the 2019 fire have seized on Edison’s admission that its equipment may have sparked the Jan. 7 fire.

“The evidence will show that five separate fires ignited at five separate SCE transmission tower bases in the same exact manner” as the 2019 fire, they wrote in a June court filing.

Delgado’s home sits next to the dirt road leading up to the towers. The Jan. 7 fire melted his backyard fence but did little more damage. In the days after the fire, he found that some of the same Edison employees he spoke to in 2019 as a witness reappeared.

“I saw the exact same people from Edison show up,” he said. “I told them your towers almost killed my family again.”
