SAN FRANCISCO (AP) — A wildfire in California wine country that may have been caused by a high-voltage transmission line called into question Pacific Gas & Electric's strategy of selectively cutting off power in windy weather to prevent blazes, and could force it to resort to even bigger blackouts affecting millions as early as this weekend.The repeated shut-offs and the prospect of longer and more widespread ones brought anger down on the utility from the governor and ordinary customers."We will hold them to account," warned Gov. Gavin Newsom, who has repeatedly blasted PG&E — the nation's largest utility — for what he calls years of mismanagement and underinvestment that have left its grid less resilient.Twice over the past two weeks, PG&E has cut power to large areas of Northern and Central California to reduce the risk of its equipment sparking fires. Nearly 2 million people lost electricity earlier this month, and then as many as a half-million this week.But PG&E's decision to shut down distribution lines but not long-distance transmission lines may have backfired this time when a blaze erupted near the Sonoma County wine country town of Geyserville.The fire burned at least 49 buildings and 34 square miles (65 square kilometers) and prompted evacuation orders for some 2,000 people. No serious injuries were reported.PG&E said a live, 230,000-volt transmission line near Geyserville had malfunctioned minutes before the fire erupted Wednesday night, and a broken "jumper" wire was found on a transmission tower.PG&E CEO Bill Johnson said it was too soon to say whether the faulty equipment sparked the fire. He said the tower had been inspected four times in the past two years and appeared to have been in excellent condition.But PG&E stock plummeted 31 percent on the news. And the blaze could mean wider blackouts ahead."It's kind of a logical next step to say, 'Well, if our high-voltage transmission lines are at risk, we've got to shut those down too,'" said Alan Scheller-Wolf, professor of operations management and an energy expert at Carnegie Mellon University.PG&E, he said, "can't win."With dangerously high winds in the forecast this weekend, the utility said it is planning another major shutdown that could hit 2 million people throughout the region starting Saturday night and last up to two days.The preparations came as firefighters simultaneously battled flames in both Northern and Southern California: the fire amid Sonoma County's vineyards, and a wind-whipped blaze that destroyed at least six homes in the Santa Clarita area near Los Angeles and led to evacuation orders covering an estimated 50,000 people.The possible link between the wine country fire and a PG&E transmission line contained grim parallels to the catastrophic fire last year that tore through the town of Paradise, killing 85 people and destroying thousands of homes in the deadliest U.S. fire in a century. State officials concluded that fire was sparked by a PG&E transmission line.The line that failed this week is newer and should have been more robust, said Michael Wara, director of the climate and energy program at Stanford University. Its failure will probably make PG&E more cautious, which means more widespread blackouts, he said."There's going to be more collateral damage," Wara said.Turning off big transmission lines reduces the stability of the electrical grid, leading to bigger outages, Wara said. Transmissions lines also take longer to re-energize because everything connected to them must be inspected, he said.PG&E's CEO has said it will take about a decade before widespread outages aren't necessary.Minimizing blackouts will require PG&E to harden its grid with stronger poles and newer equipment less likely to fall or spark. Cameras, weather sensors and a more segmented grid would allow the company to target blackouts to areas in the most danger.PG&E began resorting to large-scale shut-offs after its equipment was blamed for several blazes in recent years that killed scores of people, burned thousands of homes and ran up billions of dollars in claims that drove the utility into bankruptcy, where it is still trying to put its finances in order.The repeated and sometimes lengthy blackouts have frustrated Californians contending with uncertainty, spoiled food and disrupted plans. Many have complained about poor communication from the power company."I feel like we're being held hostage for their failings and their incompetence," said Logan Martin, 55, of Santa Rosa.This year's fire season in California has so far been mild, with fewer deaths and fewer acres burned following two years of deadly conflagrations.Experts say it is impossible to know how much the blackouts contributed to that, but PG&E has cited numerous instances of wind damage to its equipment that it said could have caused fires if the lines had been electrified.Losing power doesn't put a huge burden on firefighters, but they need to know outages are coming so they can install generators where needed, such as pumps for retardant, said Thom Porter, chief of the California Department of Forestry and Fire Protection.Firefighters sometimes draw water from rural water systems that use electrical pumps, but there have been no reports of problems getting water to fight either of the major blazes burning in California now.___Cooper reported from Phoenix.

San Diego is weighing major new rules that would ban people from living in their cars near schools and homes.The proposal would block anyone from living in their cars within 500 feet of a school or residence, and also prohibit them from living in their cars on most other city streets between 6 p.m. and 6 a.m.San Diegans living in their cars have had free reign since a judge ruled in August that its current laws were too vague. That's led to concerns from some residents in beach areas, who say they have seen people drinking in cars, as well as urinating and defecating on neighborhood streets. "I used to feel very safe walking around throughout La Jolla, Pacific Beach and everything, and there's a lot of times I don't feel as safe as I used to," said Sarah Bonesteel, a Crown Point resident. The issue of in-car living has grown along with San Diego's high housing costs. The car is one of the last pieces of shelter a homeless person may possess, Mayor Kevin Faulconer noted Tuesday. At a news conference, the mayor announced that the city would open an additional parking lot for people to legally sleep in their cars. It will be in the overflow lot across from SDCCU Stadium, providing access to housing and other services."The goal for every person or family staying here will be to access resources to get back into long-term housing," Faulconer said. Meanwhile, the city's Public Safety and Livable Neighborhoods Committee will consider the citywide restrictions Wednesday. Ann Menasche, a senior attorney with Disability Rights California, called the proposed rules draconian and said the fault is with the city. "They created the crisis by the policies of the city, and now they want to blame the victims of the crisis for the crisis itself," she said. "This is going nowhere."The new parking lot for sleeping overnight should open in about 45 days. 1874

SAN FRANCISCO (AP) — A California state audit found that the University of California wrongly admitted at least 64 wealthy students over the past six years as "favors to donors, family, and friends."California State Auditor Elaine Howle also found in the audit released Tuesday that campus staff falsely designated 22 of the applicants as student-athlete recruits because of donations from or as favors to well-connected families.The University of California, Berkeley, admitted 42 less-qualified applicants based on connections to staff, leadership, and donors.The audit was conducted in response to the national college admissions scandal that embroiled prestigious universities around the country, athletic coaches and dozens of wealthy parents. 756

  

SAN DIEGO (KGTV): The San Diego Sheriff's Department has a new tool to help keep deputies safe as they fight the war on drugs.The department just bought 15 TruNarc devices. The hand-held scanners can detect and identify drugs without the deputies having to come into physical contact.Previously, to determine what kind of drug was present at a crime scene, law enforcement would have to scoop a small amount into a kit for testing. The TruNarc uses laser technology to scan through plastic bags.This technology has become increasingly important with the rise of drugs like Fentanyl. Just a microscopic amount can cause an overdose, which has made first responders wary of handling it.The TruNarc can identify more than 200 different drugs and takes less than 2 minutes to complete the scan and give a presumptive result.San Diego Sheriff's Deputies used it earlier this month when they encountered an unconscious man in San Marcos. He was covered in white powder. Deputies called for the scanner and found the powder was Fentanyl. They called for a hazmat team to clean the scene. Officials with the department say the device likely saved the man's life, as he was able to get the medical help he needed. They say it also may have saved the officers, who didn't have to touch the man or the powder until after the scene had been made safe.The devices cost ,400 each. A grant from the Honorary Deputy Sheriff's Association helped pay for them. One has been given to each sub-station around the county. There is also one at every jail and another at the High-Intensity Drug Trafficking Area office. 1617

  

San Diego Democratic delegate Jess Durfee has attended the last four of his party's conventions to select the presidential nominee.Some days, he spends more than 15 hours attending meetings, luncheons and waiting for major speeches on the floor."There is nothing like attending a convention," he says.There is also nothing like the Democratic National Convention for 2020, which begins Monday. It's going all virtual in the midst of the Coronavirus outbreak. It starts with a keynote speech from Sen. Bernie Sanders, and will conclude Thursday when Joe Biden officially accepts the presidential nomination. Durfee used to attend with his San Diego counterparts. This year he was supposed to go to the convention in Milwaukee. Instead, he'll be joining from his home office in University Heights. "We would normally be seeing one another, even having breakfast together... We'd grab a couple of tables, and say 'these are San Diego tables, get away,'" he said, jokingly.The same virtual format will apply for the Republican National Convention, happening next week. Thad Kousser, a political scientist at UC San Diego, says these conventions are essentially one long political ad. The business of the party is not the priority - it's getting voters excited for November."The big question here is whether America will want to watch something that looks like the Zoom meetings many of us have been in all day," he said. But Kousser said there is intense political interest that could push up viewership. In 2016, 26 million people tuned in for the opening night of the Democratic National Convention.Durfee said if there is a drop off in viewership for the Democrats, he expects the same issue next week when the Republicans hold their convention. 1752
