India Drops Plan To Require Approval For AI Model Launches

Par : BeauHD
15 mars 2024 à 20:50
An anonymous reader quotes a report from TechCrunch: India is walking back on a recent AI advisory after receiving criticism from many local and global entrepreneurs and investors. The Ministry of Electronics and IT shared an updated AI advisory with industry stakeholders on Friday that no longer asked them to take the government approval before launching or deploying an AI model to users in the South Asian market. Under the revised guidelines, firms are instead advised to label under-tested and unreliable AI models to inform users of their potential fallibility or unreliability. The March 1 advisory also marked a reversal from India's previous hands-off approach to AI regulation. Less than a year ago, the ministry had declined to regulate AI growth, identifying the sector as vital to India's strategic interests. The new advisory, like the original earlier this month, hasn't been published online, but TechCrunch has reviewed a copy of it. The ministry said earlier this month that though the advisory wasn't legally binding, it signals that it's the "future of regulation" and that the government required compliance. The advisory emphasizes that AI models should not be used to share unlawful content under Indian law and should not permit bias, discrimination, or threats to the integrity of the electoral process. Intermediaries are also advised to use "consent popups" or similar mechanisms to explicitly inform users about the unreliability of AI-generated output. The ministry has retained its emphasis on ensuring that deepfakes and misinformation are easily identifiable, advising intermediaries to label or embed content with unique metadata or identifiers. It no longer requires firms to devise a technique to identify the "originator" of any particular message.

After 114 Days of Change, Broadcom CEO Acknowledges VMware-Related 'Unease'

Par : BeauHD
15 mars 2024 à 22:50
In a blog post Thursday, Broadcom CEO and President Hock Tan acknowledged the discomfort VMware customers and partners have experienced after the sweeping changes that Broadcom has instituted since it acquired the company nearly four months ago. "Of course, we recognize that this level of change has understandably created some unease among our customers and partners," writes Tan. "But all of these moves have been with the goals of innovating faster, meeting our customers' needs more effectively, and making it easier to do business with us." Ars Technica reports: Tan believes that the changes will ultimately "provide greater profitability and improved market opportunities" for channel partners. However, many IT solution provider businesses that were working with VMware have already been disrupted. For example, after buying VMware, Broadcom took over the top 2,000 VMware accounts from VMware channel partners. In a March earnings call, Tan said that Broadcom has been focused on upselling those customers. He also said Broadcom expects VMware revenue to grow double-digits quarter over quarter for the rest of the fiscal year. [...] In his blog post, Tan defended the subscription-only licensing model, calling it "the industry standard." He said VMware started accelerating its transition to this strategy in 2019, (which is before Broadcom bought VMware). He also linked to a February blog post from VMware's Prashanth Shenoy, VP of product and technical marketing for the Cloud, Infrastructure, Platforms, and Solutions group at VMware, that also noted acquisition-related "concerns" but claimed the evolution would be fiscally prudent.

Lyft and Uber To Cease Operations In Minneapolis After New Minimum Wage Law

Par : BeauHD
15 mars 2024 à 23:30
The city council of Minneapolis on Thursday voted 10-3 to allow rideshare drivers to be paid the local minimum wage of $15.57 an hour, overriding the mayor's veto of the bill. As a result, Lyft and Uber said they will cease operations in the city. From a report: Lyft said in a statement the bill was "deeply flawed" and that the ordinance makes its "operations unsustainable." "We support a minimum earning standard for drivers, but it should be done in an honest way that keeps the service affordable for riders," said a Lyft spokesperson. Uber said in a statement obtained by CNN that it's "disappointed the council chose to ignore the data and kick Uber out of the Twin Cities, putting 10,000 people out of work and leaving many stranded." The ordinance mandates rideshare drivers make at least $1.40 per mile and $0.51 per minute within Minneapolis. However, the analysis Frey referred to showed lower numbers -- $0.89 per mile and $0.49 per minute -- to make minimum wage. The mayor is imploring local politicians to come up with a solution before May 1. The rideshare services say that user prices would double if they stayed in the city.

An anonymous reader quotes a report from BleepingComputer: McDonald's restaurants are suffering global IT outages that prevent employees from taking orders and accepting payments, causing some stores to close for the day. The outages started overnight and are impacting restaurants globally, including those in the USA, Japan, Australia, Canada, the Netherlands, Italy, New Zealand, and the UK. "We are aware of a technology outage, which impacted our restaurants; the issue is now being resolved," McDonald's said in a statement to BleepingComputer. "We thank customers for their patience and apologize for any inconvenience this may have caused. Notably, the issue is not related to a cybersecurity event." In an updated statement, McDonald's says that the outage was caused by a third-party provider during a configuration change. "Many markets are back online, and the rest are in the process of coming back online. This issue was not directly caused by a cybersecurity event; rather, it was caused by a third-party provider during a configuration change."

Apple Acquires Startup DarwinAI As AI Efforts Ramp Up

According to Bloomberg, Apple has acquired Canada-based AI startup DarwinAI for an undisclosed sum. Macworld reports: Apple has reportedly folded the DarwinAI staff into its own AI team, including DarwinAI co-founder Alexander Wong, an AI researcher at the University of Waterloo who "has published over 600 refereed journal and conference papers, as well as patents, in various fields such as computational imaging, artificial intelligence, computer vision, and multimedia systems." According to its LinkedIn profile, DarwinAI is "a rapidly growing visual quality inspection company providing manufacturers an end-to-end solution to improve product quality and increase production efficiency." In layman's terms, that means Apple is likely interested in DarwinAI to streamline its manufacturing to be more efficient. That's something that could save Apple a ton of money in annual costs. Far more interesting to our consumer devices, however, is Bloomberg's report that DarwinAI's tech can be used to make AI models more efficient in general. Apple has been said to want any generative AI features to run on the device rather than the cloud, so models will need to be as small as possible and DarwinAI could definitely help there. Last month, Apple CEO Tim Cook said the iPhone maker sees "incredible breakthrough potential for generative AI, which is why we're currently investing significantly in this area. We believe that will unlock transformative opportunities for users when it comes to productivity, problem solving and more."

Days before Reddit's upcoming initial public offering (IPO), the company announced that the FTC has launched an inquiry into the company's licensing of user data to AI companies. Reddit says that it's "not surprised" by the FTC's inquiry, given the novel nature of these agreements. Axios reports: Reddit says it received a letter on Thursday, March 14, in which the FTC said it's "conducting a non-public inquiry focused on our sale, licensing, or sharing of user-generated content with third parties to train AI models." The FTC also is expected to request a meeting with Reddit, plus various documents and information. Reddit isn't the only company receiving these so-called "hold letters," according to a former FTC official who spoke with Axios on background.

Tech Layoffs Highest Since Dot-Com Crash

16 mars 2024 à 02:10
Alex Koller reports via CNBC: Since the start of the year, more than 50,000 workers have been laid off from over 200 tech companies, according to tracking website Layoffs.fyi. It's a continuation of the predominant theme of 2023, when more than 260,000 workers across nearly 1,200 tech companies lost their jobs. Alphabet, Amazon, Meta and Microsoft have all taken part in the downsizing this year, along with eBay, Unity Software, SAP and Cisco. Wall Street has largely cheered on the cost-cutting, sending many tech stocks to record highs on optimism that spending discipline coupled with efficiency gains from artificial intelligence will lead to rising profits. PayPal announced in January that it was eliminating 9% of its workforce, or about 2,500 jobs. All told, 2023 was the second-biggest year of cuts on record in the technology sector, behind only the dot-com crash in 2001, according to outplacement firm Challenger, Gray & Christmas. Not since the spectacular flameouts of Pets.com, eToys and Webvan have so many tech workers lost their jobs in such a short period of time. Last month's job cut count was the highest of any February since 2009, when the financial crisis forced companies into cash preservation mode. CNBC spoke to a dozen people who have been laid off from tech jobs in the past year or so about their experiences navigating the labor market. Some spoke on the condition that CNBC not use their names or write about the details of their situation. Taken together, they paint a picture of an increasingly competitive market with job listings that include exacting requirements for qualification and come with lower pay than their prior gigs. It's a particularly confounding situation for software developers and data scientists, who just a couple of years ago had some of the most marketable and highly valued skills on the planet, and are now considering whether they need to exit the industry to find employment.

First Large Offshore US Wind Farm Delivers Power To Local Grid

Par : BeauHD
16 mars 2024 à 03:30
An anonymous reader quotes a report from NPR: America's first commercial-scale offshore wind farm is officially open, a long-awaited moment that helps pave the way for a succession of large wind farms. Danish wind energy developer Orsted and the utility Eversource built a 12-turbine wind farm called South Fork Wind 35 miles (56 kilometers) east of Montauk Point, New York. New York Gov. Kathy Hochul went to Long Island Thursday to announce that the turbines are delivering clean power to the local electric grid, flipping a massive light switch to "turn on the future." Interior Secretary Deb Haaland was also on hand. Achieving commercial scale is a turning point for the industry, but what's next? Experts say the nation needs a major buildout of this type of clean electricity to address climate change. Offshore wind is central to both national and state plans to transition to a carbon-free electricity system. The Biden administration has approved six commercial-scale offshore wind energy projects, and auctioned lease areas for offshore wind for the first time off the Pacific and Gulf of Mexico coasts. New York picked two more projects last month to power more than 1 million homes. This is just the beginning, Hochul said. She said the completion of South Fork shows that New York will aggressively pursue climate change solutions to save future generations from a world that otherwise could be dangerous. South Fork can generate 132 megawatts of offshore wind energy to power more than 70,000 homes. "It's great to be first, we want to make sure we're not the last. That's why we're showing other states how it can be done, why we're moving forward, on to other projects," Hochul told The Associated Press in an exclusive interview before the announcement. "This is the date and the time that people will look back in the history of our nation and say, 'This is when it changed,'" Hochul added. South Fork will generate more than four times the power of a five-turbine pilot project developed earlier off the coast of Rhode Island, and unlike that subsidized test project, was developed after Orsted and Eversource were chosen in a competitive bidding process to supply power to Long Island. Orsted CEO Mads Nipper called the opening a major milestone that proves large offshore wind farms can be built, both in the United States and in other countries with little or no offshore wind energy currently. Another large U.S. offshore wind farm began producing energy in January, with plans to eventually power 62 turbines, enough to generate electricity for 400,000 homes.

Scientists Reveal Never-Before-Seen Map of the Milky Way's Central Engine

Par : BeauHD
16 mars 2024 à 07:00
With funding from NASA, researchers from Villanova University have obtained a never-before-seen view of the central engine at the heart of our galaxy. Space.com reports: The new map of this central region of the Milky Way, which took four years to assemble, reveals the relationship between magnetic fields at the heart of our galaxy and the cold dust structures that dwell there. This dust forms the building blocks of stars, planets, and, ultimately, life as we know it. The central engine of the Milky Way drives this process. That means a clearer picture of dust and magnetic interactions builds a better understanding of the Milky Way and our place within it. The team's findings also have implications beyond our galaxy, offering glimpses of how dust and magnetic fields interact in the central engines of other galaxies. "The center of the Milky Way and most of the space between stars is filled with a lot of dust, and this is important for our galaxy's life cycle," David Chuss, research team leader and a physics professor at Villanova University, told Space.com. "What we looked at was light emitted from these cool dust grains produced by heavy elements forged in stars and dispersed when those stars die and explode." [...] Chuss and colleagues received funding from NASA to investigate this dusty central zone using the Stratospheric Observatory for Infrared Astronomy (SOFIA), which was a telescope that circled the globe at an altitude of 45,000 feet (13,716 meters) aboard a Boeing 747 plane. The project's Far-Infrared Polarimetric Large Area CMZ Exploration (FIREPLACE) created an infrared map that spans around 500 light-years across the center of the Milky Way over nine flights. Using measurements of the polarization of the radiation emitted from dust that is aligned with magnetic fields, the intricate structure of those magnetic fields themselves was inferred by the team. This was then overlaid onto a three-color map that shows warm dust with a pink hue and cool dust clouds in blue. The image also shows radio-wave-emitting filaments in yellow. "This is a journey, not a destination, but what we've found is this is a very complicated thing. The directions of the magnetic field vary all across the clouds at the center of the Milky Way," Chuss explained. "This is the first step in trying to figure out how the field that we see in the radiowaves across these large organized filaments may relate to the rest of the dynamics of the center of the Milky Way." Chuss explained that this complicated picture of magnetic fields was something that he and the FIREPLACE team had expected to see with the new SOFIA map; the observations agreed with smaller-scale infrared and radio wave observations previously made of the heart of the Milky Way. Where this new map, however, really comes into its own is the sheer scale. It manages to reveal some never-before mapped regions. The fine detail woven into it is stunning as well. A preprint version of the SOFIA data is available on arXiv.

Is AI Ruining Etsy?

Emily Dreibelbis reports via PCMag: Etsy's reputation as a haven for small, independent creators has come into question as tools like Midjourney have made it easy to list art without disclosing that it's been AI-generated, and shoppers are not happy. "The fact that it's AI isn't listed anywhere," says one Reddit user who purchased a stock photo on Etsy that seemed suspiciously low cost with glowing reviews. "I was so mad at myself for not noticing it was AI before purchasing." [...] "Being avid user of Etsy, I really enjoy supporting small businesses and the talent that goes into their work," the buyer tells PCMag in a private message. "Shops such as we discussed selling massive amounts of AI-generated images take away from genuine sellers who put hours into perfecting their craft." Etsy's seller policy does not mention artificial intelligence. The platform is still determining the place AI-generated works have on the site, a source tells PCMag. Complicating matters, some sellers take AI-generated images and modify them, adding a hint of human artistry. Etsy also has a policy regarding when sellers can claim an item is "handmade," but it also does not mention AI and appears virtually unenforceable. [...] Beyond the legalities, Etsy shoppers debate the ethical and economic implications. One argues it devalues the work, citing an ancient example of explorer Mansa Musa handing out fake gold during his travels, inflating the overall supply and tanking the market. If anyone can create art at the push of a button, what defines an artist's work? And what role does Etsy play in answering that question?

Florida Man Sues G.M. and LexisNexis Over Sale of His Cadillac Data

An anonymous reader quotes a report from the New York Times: When Romeo Chicco tried to get auto insurance in December, seven different companies rejected him. When he eventually obtained insurance, it was nearly double the rate he was previously paying. According to a federal complaint filed this week seeking class-action status, it was because his 2021 Cadillac XT6 had been spying on him. Modern cars have been called "smartphones with wheels," because they are connected to the internet and packed with sensors and cameras. According to the complaint, an agent at Liberty Mutual told Mr. Chicco that he had been rejected because of information in his "LexisNexis report." LexisNexis Risk Solutions, a data broker, has traditionally kept tabs for insurers on drivers' moving violations, prior insurance coverage and accidents. When Mr. Chicco requested his LexisNexis file, it contained details about 258 trips he had taken in his Cadillac over the past six months. His file included the distance he had driven, when the trips started and ended, and an accounting of any speeding and hard braking or accelerating. The data had been provided by General Motors -- the manufacturer of his Cadillac. In a complaint against General Motors and LexisNexis Risk Solutions filed in the U.S. District Court for the Southern District of Florida, Mr. Chicco accused the companies of violation of privacy and consumer protection laws. The lawsuit follows a report by The New York Times that, unknown to consumers, automakers have been sharing information on their driving behavior with the insurance industry, resulting in increased insurance rates for some drivers.

5-Year Study Finds No Brain Abnormalities In 'Havana Syndrome' Patients

An anonymous reader quotes a report from CBC News: An array of advanced tests found no brain injuries or degeneration among U.S. diplomats and other government employees who suffer mysterious health problems once dubbed "Havana syndrome," researchers reported Monday. The National Institutes of Health's (NIH) nearly five-year study offers no explanation for symptoms including headaches, balance problems and difficulties with thinking and sleep that were first reported in Cuba in 2016 and later by hundreds of American personnel in multiple countries. But it did contradict some earlier findings that raised the spectre of brain injuries in people experiencing what the State Department now calls "anomalous health incidents." "These individuals have real symptoms and are going through a very tough time," said Dr. Leighton Chan, NIH's chief of rehabilitation medicine, who helped lead the research. "They can be quite profound, disabling and difficult to treat." Yet sophisticated MRI scans detected no significant differences in brain volume, structure or white matter -- signs of injury or degeneration -- when Havana syndrome patients were compared to healthy government workers with similar jobs, including some in the same embassy. Nor were there significant differences in cognitive and other tests, according to findings published in the Journal of the American Medical Association.

Sony Reportedly Pauses PSVR 2 Production Due To Low Sales

According to Bloomberg, Sony has paused production of its PlayStation VR 2 virtual reality headset, as sales have "slowed progressively" since its February 2023 launch. Road to VR reports: Citing people familiar with the company's plans, Sony has produced "well over 2 million units" since launch, noting that stocks of the $550 headset are building up. The report alleges the surplus is "throughout Sony's supply chain," indicating the issue isn't confined to a single location, but is spread across different stages of Sony's production and distribution network. This follows news that Sony Interactive Entertainment laid off eight percent of the company, which affected a number of its first-party game studios also involved in VR game production. Sony entirely shuttered its London Studio, which created VR action-adventure game Blood & Truth (2019), and reduced headcount at Firesprite, the studio behind PSVR 2 exclusive Horizon Call of the Mountain. Meanwhile, Sony is making PSVR 2 officially compatible with PC VR games, as the company hopes to release some sort of PC support for the headset later this year. How and when Sony will do that is still unknown, although the move underlines just how little confidence the company has in its future lineup of exclusive content just one year after launch of PSVR 2.

BitTorrent Is No Longer the 'King' of Upstream Internet Traffic

Par : BeauHD
19 mars 2024 à 00:02
An anonymous reader quotes a report from TorrentFreak: Back in 2004, in the pre-Web 2.0 era, research indicated that BitTorrent was responsible for an impressive 35% of all Internet traffic. At the time, file-sharing via peer-to-peer networks was the main traffic driver as no other services consumed large amounts of bandwidth. Fast-forward two decades and these statistics are ancient history. With the growth of video streaming, including services such as YouTube, Netflix, and TikTok, file-sharing traffic is nothing more than a drop in today's data pool. [...] This week, Canadian broadband management company Sandvine released its latest Global Internet Phenomena Report which makes it clear that BitTorrent no longer leads any charts. The latest data show that video and social media are the leading drivers of downstream traffic, accounting for more than half of all fixed access and mobile data worldwide. Needless to say, BitTorrent is nowhere to be found in the list of 'top apps'. Looking at upstream traffic, BitTorrent still has some relevance on fixed access networks where it accounts for 4% of the bandwidth. However, it's been surpassed by cloud storage apps, FaceTime, Google, and YouTube. On mobile connections, BitTorrent no longer makes it into the top ten. The average of 46 MB upstream traffic per subscriber shouldn't impress any file-sharer. However, since only a small percentage of all subscribers use BitTorrent, the upstream traffic per user is of course much higher.

Indiana Becomes 9th State To Make CS a High School Graduation Requirement

Par : BeauHD
19 mars 2024 à 00:45
Longtime Slashdot reader theodp writes: Last October, tech-backed nonprofit Code.org publicly called out Indiana in its 2023 State of Computer Science Education report, advising the Hoosier state it needed to heed Code.org's new policy recommendation and "adopt a graduation requirement for all high school students in computer science." Having already joined 49 other Governors who signed a Code.org-organized compact calling for increased K-12 CS education in his state after coming under pressure from hundreds of the nation's tech, business, and nonprofit leaders, Indiana Governor Eric J. Holcomb apparently didn't need much convincing. "We must prepare our students for a digitally driven world by requiring Computer Science to graduate from high school," Holcomb proclaimed in his January State of the State Address. Two months later -- following Microsoft-applauded testimony for legislation to make it so by Code.org partners College Board and Nextech (the Indiana Code.org Regional Partner which is also paid by the Indiana Dept. of Education to prepare educators to teach K-12 CS, including Code.org's curriculum) -- Holcomb on Wednesday signed House Bill 1243 into law, making CS a HS graduation requirement. The IndyStar reports students beginning with the Class of 2029 will be required to take a computer science class that must include instruction in algorithms and programming, computing systems, data and analysis, impacts of computing and networks and the internet. The new law is not Holcomb's first foray into K-12 CS education. Back in 2017, Holcomb and Indiana struck a deal giving Infosys (a big Code.org donor) the largest state incentive package ever -- $31M to bring 2,000 tech employees to Central Indiana — that also promised to make Indiana kids more CS savvy through the Infosys Foundation USA, headed at the time by Vandana Sikka, a Code.org Board member and wife of Infosys CEO Vishal Sikka. Following the announcement of the now-stalled deal, Holcomb led a delegation to Silicon Valley where he and Indiana University (IU) President Michael McRobbie joined Code.org CEO Hadi Partovi and Infosys CEO Vishal Sikka on a Thought Leader panel at the Infosys Confluence 2017 conference to discuss Preparing America for Tomorrow. At the accompanying Infosys Crossroads 2017 CS education conference, speakers included Sikka's wife Vandana, McRobbie's wife Laurie Burns McRobbie, Nextech President and co-CEO Karen Jung, Code.org execs, and additional IU educators. Later that year, IU 'First Lady' Laurie Burns McRobbie announced that Indiana would offer the IU Bloomington campus as a venue for Infosys Foundation USA's inaugural Pathfinders Summer Institute, a national event for K-12 teacher education in CS that offered professional development from Code.org and Nextech, as well as an unusual circumvent-your-school's-approval-and-name-your-own-stipend funding arrangement for teachers via an Infosys partnership with the NSF and DonorsChoose that was unveiled at the White House. And that, Schoolhouse Rock Fans, is one more example of how Microsoft's National Talent Strategy is becoming Code.org-celebrated K-12 CS state laws!

Hertz CEO Resigns After Blowing Big Gamble On EVs

Press2ToContinue quotes a report from the Gateway Pundit: Stephen Scherr, chief executive officer of Hertz Global Holdings Inc. and a member of its board of directors, will step down on March 31, following the car rental company's largest quarterly loss since 2020 after a risky bet on electric vehicles. According to Fox Business, Scherr is working with Gil West, former chief operating officer of Delta Airlines and General Motors' Cruise unit, to ensure a smooth transition. West will officially start his new role at Hertz on April 1. Scherr, 59, joined Hertz two years ago as the company was emerging from bankruptcy and putting a big focus on EVs during that time. Hertz soon discovered that EVs are more expensive to maintain than they had initially thought. Scherr reportedly told investors that Hertz's profits experienced a $348 million loss, which he blamed EVs for. In January, Hertz announced its plan to offload 20,000 electric vehicles from its U.S. fleet throughout 2024, and switch back to gas cars. In November, the Associated Press reported on a Consumer Reports survey that found EVs from the 2021 to 2023 model years are significantly less reliable than gasoline-powered vehicles. A whopping eighty percent less reliable, according to the AP, particularly with battery and charging systems, as well as fit issues with body panels and interiors. Car dealers and manufacturers are reportedly also struggling to sell EVs despite using deep discounts and promotional tactics. In 2021, Hertz announced plans to order 100,000 Tesla vehicles by the end of 2022. It later said it would buy "up to" 65,000 Polestar EVs for its rental fleet over the next five years.

Nvidia Reveals Blackwell B200 GPU, the 'World's Most Powerful Chip' For AI

Par : BeauHD
19 mars 2024 à 02:02
Sean Hollister reports via The Verge: Nvidia's must-have H100 AI chip made it a multitrillion-dollar company, one that may be worth more than Alphabet and Amazon, and competitors have been fighting to catch up. But perhaps Nvidia is about to extend its lead -- with the new Blackwell B200 GPU and GB200 "superchip." Nvidia says the new B200 GPU offers up to 20 petaflops of FP4 horsepower from its 208 billion transistors and that a GB200 that combines two of those GPUs with a single Grace CPU can offer 30 times the performance for LLM inference workloads while also potentially being substantially more efficient. It "reduces cost and energy consumption by up to 25x" over an H100, says Nvidia. Training a 1.8 trillion parameter model would have previously taken 8,000 Hopper GPUs and 15 megawatts of power, Nvidia claims. Today, Nvidia's CEO says 2,000 Blackwell GPUs can do it while consuming just four megawatts. On a GPT-3 LLM benchmark with 175 billion parameters, Nvidia says the GB200 has a somewhat more modest seven times the performance of an H100, and Nvidia says it offers 4x the training speed. Nvidia told journalists one of the key improvements is a second-gen transformer engine that doubles the compute, bandwidth, and model size by using four bits for each neuron instead of eight (thus, the 20 petaflops of FP4 I mentioned earlier). A second key difference only comes when you link up huge numbers of these GPUs: a next-gen NVLink switch that lets 576 GPUs talk to each other, with 1.8 terabytes per second of bidirectional bandwidth. That required Nvidia to build an entire new network switch chip, one with 50 billion transistors and some of its own onboard compute: 3.6 teraflops of FP8, says Nvidia.

EPA Bans Chrysotile Asbestos

Par : BeauHD
19 mars 2024 à 03:30
An anonymous reader quotes a report from the Associated Press: The Environmental Protection Agency on Monday announced a comprehensive ban on asbestos, a carcinogen that kills tens of thousands of Americans every year but is still used in some chlorine bleach, brake pads and other products. The final rule marks a major expansion of EPA regulation under a landmark 2016 law that overhauled regulations governing tens of thousands of toxic chemicals in everyday products, from household cleaners to clothing and furniture. The new rule would ban chrysotile asbestos, the only ongoing use of asbestos in the United States. The substance is found in products such as brake linings and gaskets and is used to manufacture chlorine bleach and sodium hydroxide, also known as caustic soda, including some that is used for water purification. [...] The 2016 law authorized new rules for tens of thousands of toxic chemicals found in everyday products, including substances such as asbestos and trichloroethylene that for decades have been known to cause cancer yet were largely unregulated under federal law. Known as the Frank Lautenberg Chemical Safety Act, the law was intended to clear up a hodgepodge of state rules governing chemicals and update the Toxic Substances Control Act, a 1976 law that had remained unchanged for 40 years. The EPA banned asbestos in 1989, but the rule was largely overturned by a 1991 Court of Appeals decision that weakened the EPA's authority under TSCA to address risks to human health from asbestos or other existing chemicals. The 2016 law required the EPA to evaluate chemicals and put in place protections against unreasonable risks. Asbestos, which was once common in home insulation and other products, is banned in more than 50 countries, and its use in the U.S. has been declining for decades. The only form of asbestos known to be currently imported, processed or distributed for use in the U.S. is chrysotile asbestos, which is imported primarily from Brazil and Russia. It is used by the chlor-alkali industry, which produces bleach, caustic soda and other products. Most consumer products that historically contained chrysotile asbestos have been discontinued. While chlorine is a commonly used disinfectant in water treatment, there are only eight chlor-alkali plants in the U.S. that still use asbestos diaphragms to produce chlorine and sodium hydroxide. The plants are mostly located in Louisiana and Texas. The use of asbestos diaphragms has been declining and now accounts for less than one-third of the chlor-alkali production in the U.S., the EPA said. The EPA rule will ban imports of asbestos for chlor-alkali as soon as the rule is published but will phase in prohibitions on chlor-alkali use over five or more years to provide what the agency called "a reasonable transition period." A ban on most other uses of asbestos will effect in two years. A ban on asbestos in oilfield brake blocks, aftermarket automotive brakes and linings and other gaskets will take effect in six months. The EPA rule allows asbestos-containing sheet gaskets to be used until 2037 at the U.S. Department of Energy's Savannah River Site in South Carolina to ensure that safe disposal of nuclear materials can continue on schedule. Separately, the EPA is also evaluating so-called legacy uses of asbestos in older buildings, including schools and industrial sites, to determine possible public health risks. A final risk evaluation is expected by the end of the year.
