Hillary Clinton and U.S. election officials said they are concerned disinformation generated and spread by AI could threaten the 2024 presidential election [non-paywalled link]. WSJ: Clinton, a former secretary of state and 2016 presidential candidate, said she thinks foreign actors like Russian President Vladimir Putin could use AI to interfere in elections in the U.S. and elsewhere. Dozens of countries are running elections this year. "Anybody who's not worried is not paying attention," Clinton said Thursday at Columbia University, where election officials and tech executives discussed how AI could impact global elections.

She added: "It could only be a very small handful of people in St. Petersburg or Moldova or wherever they are right now who are lighting the fire, but because of the algorithms everyone gets burned." Clinton said Putin tried to undermine her before the 2016 election by spreading disinformation on Facebook, Twitter and Snapchat about "all these terrible things" she purportedly did. "I don't think any of us understood it," she said. "I did not understand it. I can tell you my campaign did not understand it. The so-called dark web was filled with these kinds of memes and stories and videos of all sorts portraying me in all kinds of less than flattering ways." Clinton added: "What they did to me was primitive and what we're talking about now is the leap in technology."

The US has seen a significant increase in student absenteeism since the pandemic closed schools four years ago, with an estimated 26% of public school students considered chronically absent in the last school year, up from 15% before the pandemic, according to data from 40 states and Washington, D.C. A report adds: The increases have occurred in districts big and small, and across income and race. For districts in wealthier areas, chronic absenteeism rates have about doubled, to 19 percent in the 2022-23 school year from 10 percent before the pandemic, a New York Times analysis of the data found. Poor communities, which started with elevated rates of student absenteeism, are facing an even bigger crisis: Around 32 percent of students in the poorest districts were chronically absent in the 2022-23 school year, up from 19 percent before the pandemic. Even districts that reopened quickly during the pandemic, in fall 2020, have seen vast increases.

The Palisades Nuclear Plant in Michigan has won a $1.5 billion conditional federal loan to reopen after being closed for decommissioning in 2022. Canary Media reports: If the loan is granted (subject to Holtec meeting closing conditions) and the 800-megawatt reactor located on Lake Michigan is repowered, it would be the first nuclear plant in the U.S. to reopen after being closed for decommissioning. Surprisingly, it would be just the second or third reactor to restart in the history of global civil nuclear power, according to Mycle Schneider, lead author of the World Nuclear Industry Status Report 2023, in an interview with Bulletin of the Atomic Scientists.

Holtec purchased Palisades a month after it shut down with plans to mothball the site, but plans changed. Now the firm, which specializes in nuclear waste management and decommissioning (as opposed to rebuilding and operating nuclear plants), intends to revive the plant instead. Holtec plans to get the power plant restarted by the end of 2025, a breathtakingly aspirational target given nuclear's history of missing construction and cost targets. The Palisades plant was closed by utility Entergy in May 2022 due to financial issues after operating for more than a half-century. And while the plant had a strong operational performance record in recent years, it also has a sobering history of shutdowns due to failures of critical equipment, as well as broken fuel rods and fuel-spill incidents. The site was shut down for the final time a few days ahead of schedule due to concerns about the reliability of a key piece of equipment.

When it was operating at its peak, the plant provided more than 600 high-paying jobs, many unionized. If restarted, the plant could drive up to $363 million in regional economic impact, according to Michigan Governor Gretchen Whitmer, a Democrat. That's why Whitmer and a bipartisan coalition of lawmakers back resurrecting the retired reactor. Local business owners and residents are "largely supportive" of the plan as well, according to local news site MLive. The state's 2024 budget devotes $150 million to the project. Still, the revival of the dormant Palisades faces its share of headwinds.

An anonymous reader shares a report: New York City announced a new permitting system for companies interested in testing autonomous vehicles on its roads, including a requirement that a human safety driver sit behind the steering wheel at all times. As cities like San Francisco continue to grapple with the problems posed by fully driverless for-hire vehicles, New York City is trying to get ahead of the problem by outlining what it calls "a rigorous permitting program" that it claims will ensure applicants are "ready to test their technology in the country's most challenging urban environment safely and proficiently."

"This technology is coming whether we like it or not," Mayor Eric Adams said in a statement to The Verge, "so we're going to make sure that we get it right." The requirements would exclude companies without previous autonomous vehicle testing experience in other cities. Applicants would need to submit information from previous tests, including details on any crashes that occurred and how often safety drivers have to take control of the vehicle (also known in California as "disengagements"). And in what is sure to be the most controversial provision, fully driverless vehicles won't be permitted to test on the city's public roads; only vehicles with safety drivers will be allowed.

Neil Irwin reports via Axios: The dearth of productivity growth over the last couple of decades has held back incomes in the U.S. and other rich countries, according to a report out Wednesday from the McKinsey Global Institute, the research arm of the global consultancy. Productivity growth has been weak in the U.S. and Western Europe since the 2008 global financial crisis, but things looked better among many emerging markets. The McKinsey report finds that global labor productivity growth was 2.3% a year from 1997 to 2022, a rapid rate that has increased incomes and quality of life in large parts of the world. China and India account for the largest portion of that surge -- half of overall global productivity improvement, with other emerging markets accounting for another 25%, led by Central and Eastern Europe and emerging Asian economies.

In the U.S., the report finds that the decline in capital investment following the 2008 financial crisis has resulted in a $4,500 lower per-capita GDP in 2022 than it would have if pre-crisis trends had continued. Rapid advances in manufacturing technology, especially for electronics, petered out in the same time period, subtracting another $5,000 from per-capita GDP. "Digitization was much discussed as the main candidate to rev up productivity again, but its impact failed to spread beyond" the tech sector, the authors write. The authors are optimistic that a confluence of factors will make the years ahead different.

The rise in global interest rates and inflation are evidence of stronger global demand. Many countries are experiencing labor shortages that may incentivize more productivity-enhancing investment. And artificial intelligence and related technologies create big opportunities. "Inflationary pressure and rising interest rates could be signs that we are leaving behind secular stagnation and entering an era of higher demand and investment," the report finds. "In corporate boardrooms around the world right now, there's a tremendous amount of conversation associated with [generative] AI, and I think there's a broad acknowledgment that this could very much transform productivity at the company level," Olivia White, a McKinsey senior partner and co-author of the report, tells Axios. "Another thing that's happening right now is the conversation about labor. Labor markets in all advanced economies, and the U.S. is really sort of top of the heap, are very, very tight right now. So there's a lot of conversation around what do we do to make the people that we have as productive as they can be?"

The U.S. State Department has offered up to $10 million for information on the "Blackcat" ransomware gang who hit the UnitedHealth Group's tech unit and snarled insurance payments across America. From a report: "The ALPHV Blackcat ransomware-as-a-service group compromised computer networks of critical infrastructure sectors in the United States and worldwide," the department said in a statement announcing the reward offer.

UnitedHealth said last week it was beginning to clear a medical claims backlog of more than $14 billion as it brought its services back online following the cyberattack, which caused wide-ranging disruption starting in late February. UnitedHealth's tech unit, Change Healthcare, plays a critical role in processing payments from insurance companies to practitioners, and the outage caused by the cyberattack has in some cases left patients and doctors out of pocket. The toll on the community health centers that serve more than 30 million poor and uninsured patients has been especially harsh.

The amount of hydropower generated in the Western US last year was the lowest it's been in more than two decades -- and 2024 isn't looking much better. From a report: Hydropower generation in the region fell by 11 percent during the 2022-2023 water year compared to the year prior, according to preliminary data from the Energy Information Administration's Electricity Data Browser -- its lowest point since 2001. That includes states west of the Dakotas and Texas, where 60 percent of the nation's hydropower was generated. These also happen to be the states -- including California, Nevada, Arizona, and New Mexico -- that climate change is increasingly sucking dry. And in a reversal of fortunes, typically wetter states in the Northeast -- normally powerhouses for hydropower generation -- were the hardest hit. You can blame extreme heat and drought for the drop in hydropower last year. This creates a vicious cycle: drought reduces the amount of clean energy available from hydroelectric dams. To avoid energy shortfalls, utilities wind up relying on fossil fuels to make up the difference. That leads to more of the greenhouse gas emissions causing climate change, which makes droughts worse.

An anonymous reader quotes a report from The Register: It's sanctions central at the US Treasury this week as a further 15 are slapped on organizations and individuals in Russia. The Treasury's Office of Foreign Assets Control (OFAC) designated 13 organizations and two individuals -- all concerning financial services organizations, including cryptocurrency exchanges that offered services to already-sanctioned dark web marketplaces in Russia, and those who helped run them. Five of the 13 freshly designated entities were also controlled by individuals who were already sanctioned. The latest round of trade restrictions were placed on those who are believed to have helped evade existing US sanctions.

"Many of the individuals and entities designated today facilitated transactions or offered other services that helped OFAC-designated entities evade sanctions," an OFAC statement read. "These designations build upon OFAC's February 23, 2024 action to target companies servicing Russia's core financial infrastructure and curtail Russia's use of the international financial system to further its war against Ukraine." They follow the initial seven sanctions announced on Monday, all relating to Chinese nationals and members of Beijing's APT31 offensive cyber outfit.

Earlier today, the U.S. and U.K. accused hackers linked to the Chinese state of being behind "malicious" cyber campaigns targeting political figures. The U.K. government also blamed China for a 2021 cyberattack that compromised the personal information of millions of U.K. voters. In response, PBS reports that the U.S. and British government announced sanctions against a company and two people linked to the Chinese government. From the report: Officials said those sanctioned are responsible for a hack that may have gained access to information on tens of millions of U.K. voters held by the Electoral Commission, as well as for cyberespionage targeting lawmakers who have been outspoken about the China threat. The Foreign Office said the hack of the election registers "has not had an impact on electoral processes, has not affected the rights or access to the democratic process of any individual, nor has it affected electoral registration." The Electoral Commission said in August that it identified a breach of its system in October 2022, though it added that "hostile actors" had first been able to access its servers since 2021. At the time, the watchdog said the data included the names and addresses of registered voters. But it said that much of the information was already in the public domain.

In Washington, the Treasury Department said it sanctioned Wuhan Xiaoruizhi Science and Technology Company Ltd., which it calls a Chinese Ministry of State Security front company that has "served as cover for multiple malicious cyberoperations." It named two Chinese nationals, Zhao Guangzong and Ni Gaobin, affiliated with the Wuhan company, for cyberoperations that targeted U.S. critical infrastructure sectors, "directly endangering U.S. national security." Separately, British cybersecurity officials said that Chinese government-affiliated hackers "conducted reconnaissance activity" against British parliamentarians who are critical of Beijing in 2021. They said no parliamentary accounts were successfully compromised.

Three lawmakers, including former Conservative Party leader Iain Duncan Smith, told reporters Monday they have been "subjected to harassment, impersonation and attempted hacking from China for some time." Duncan Smith said in one example, hackers impersonating him used fake email addresses to write to his contacts. The politicians are members of the Inter-Parliamentary Alliance on China, an international pressure group focused on countering Beijing's growing influence and calling out alleged rights abuses by the Chinese government.

Jessica Lyons reports via The Register: Vulnerabilities in common Electronic Logging Devices (ELDs) required in US commercial trucks could be present in over 14 million medium- and heavy-duty rigs, according to boffins at Colorado State University. In a paper presented at the 2024 Network and Distributed System Security Symposium, associate professor Jeremy Daily and systems engineering graduate students Jake Jepson and Rik Chatterjee demonstrated how ELDs can be accessed over Bluetooth or Wi-Fi connections to take control of a truck, manipulate data, and spread malware between vehicles. "These findings highlight an urgent need to improve the security posture in ELD systems," the trio wrote [PDF].

The authors did not specify brands or models of ELDs that are vulnerable to the security flaws they highlight in the paper. But they do note there's not too much diversity of products on the market. While there are some 880 devices registered, "only a few tens of distinct ELD models" have hit the road in commercial trucks. A federal mandate requires most heavy-duty trucks to be equipped with ELDs, which track driving hours. These systems also log data on engine operation, vehicle movement and distances driven -- but they aren't required to have tested safety controls built in. And according to the researchers, they can be wirelessly manipulated by another car on the road to, for example, force a truck to pull over.

The academics pointed out three vulnerabilities in ELDs. They used bench level testing systems for the demo, as well as additional testing on a moving 2014 Kenworth T270 Class 6 research truck equipped with a vulnerable ELD. [...] For one of the attacks, the boffins showed how anyone within wireless range could use the device's Wi-Fi and Bluetooth radios to send an arbitrary CAN message that could disrupt of some of the vehicle's systems. A second attack scenario, which also required the attacker to be within wireless range, involved connecting to the device and uploading malicious firmware to manipulate data and vehicle operations. Finally, in what the authors described as the "most concerning" scenario, they uploaded a truck-to-truck worm. The worm uses the compromised device's Wi-Fi capabilities to search for other vulnerable ELDs nearby. After finding the right ELDs, the worm uses default credentials to establish a connection, drops its malicious code on the next ELD, overwrites existing firmware, and then starts the process over again, scanning for additional devices. "Such an attack could lead to widespread disruptions in commercial fleets, with severe safety and operational implications," the researchers warned.

The U.S. Department of Transportation has announced it will conduct a review of the data practices of the country's ten largest airlines, amid concerns over potential misuse of customer information for upselling, overcharging, targeted advertising, and third-party data sales, as well as the security of systems handling sensitive data such as passport numbers. From a report: The probe will look at air carriers' policies and procedures to determine if they are safeguarding personal info properly, unfairly or deceptively monetizing it, or sharing it with third parties, the agency said yesterday. If they're indeed doing anything "problematic," they can look forward to scrutiny, fines, and new rules, says the DOT. "Airline passengers should have confidence that their personal information is not being shared improperly with third parties or mishandled by employees," said US Transportation Secretary Pete Buttigieg.

"This review of airline practices is the beginning of a new initiative by DOT to ensure airlines are being good stewards of sensitive passenger data." The ten airlines going under the magnifying glass are Delta, United, American, Southwest, Alaska, JetBlue, Spirit, Frontier, Hawaiian and Allegiant.

An anonymous reader shares a report: On Monday, the Biden administration announced that six new countries had joined an international coalition to fight the proliferation of commercial spyware, sold by companies such as NSO Group or Intellexa. Now, some investors have announced that they too are committed to fighting spyware. But at least one of those investors, Paladin Capital Group, has previously invested in a company that developed malware, according to a leaked 2021-dated slide deck obtained by TechCrunch, although the firm tells TechCrunch it "got out" of the firm some time ago.

In the last couple of years, the U.S. government has led an effort to limit or at least restrain the use of spyware across the world by putting surveillance tech makers like NSO Group, Candiru, and Intellexa on blocklists, as well as imposing export controls on those companies and visa restrictions on people involved in the industry. More recently, the government has imposed economic sanctions not only on companies, but also directly on the executive who founded Intellexa. These actions have put others in the spyware industry on alert. In a call with reporters on Monday that TechCrunch attended, a senior Biden administration official said that a representative from Paladin participated in meetings at the White House on March 7, as well as this week in Seoul, where governments gathered for the Summit for Democracy to discuss spyware.

Paladin, one of the biggest investors in cybersecurity startups, and several other venture firms published a set of voluntary investment principles, noting that they would invest in companies that "enhance the defense, national security, and foreign policy interests of free and open societies." "For us, it was an important first step in having an investor outline both recognition that investments should not be going towards companies that are undertaking selling products, and selling to clients that can undermine free and fair societies," the senior administration official said in the call, where journalists agreed not to quote the officials by name.

The Coalition for App Fairness, an industry body that represents Epic, Spotify, Match Group and Proton among others, issued the following statement following the U.S. announcing it had sued Apple: "With today's announcement, the Department of Justice is taking a strong stand against Apple's stranglehold over the mobile app ecosystem, which stifles competition and hurts American consumers and developers alike. The DOJ complaint details Apple's long history of illegal conduct -- abusing their App Store guidelines and developer agreements to increase prices, extract exorbitant fees, degrade user experiences, and choke off competition. The DOJ joins regulators around the world, who have recognized the many harms of Apple's abusive behavior and are working to address it. As this case unfolds in the coming years more must be done now to end the anticompetitive practices of all mobile app gatekeepers. It remains imperative that Congress pass bipartisan legislation, like the Open App Markets Act, to create a free and open mobile app marketplace."

The Justice Department sued Apple on Thursday, alleging the tech giant blocked software developers and mobile gaming companies from offering better options on the iPhone, resulting in higher prices for consumers. WSJ: The government's antitrust complaint, filed in a New Jersey federal court, alleges Apple used its control of the iPhone to prevent competitors from offering innovative services such as digital wallets and limited the functionality of hardware products that compete with Apple's own devices. The suit also claims that Apple makes it difficult for users to switch to devices that don't use Apple's operating system, such as Android smartphones.

"Consumers should not have to pay higher prices because companies violate the antitrust laws," Attorney General Merrick Garland said in a statement. Apple said it plans to vigorously defend against the lawsuit. "This lawsuit threatens who we are and the principles that set Apple products apart in fiercely competitive markets," an Apple spokesman said in a statement. "If successful, it would hinder our ability to create the kind of technology people expect from Apple -- where hardware, software, and services intersect." The case against Apple is the last shoe to drop on the big four tech giants by U.S. antitrust officials.

sinij shares a report from the New York Post: The Biden administration finalized its crackdown on gas cars Wednesday, with the Environmental Protection Agency announcing drastic climate regulations meant to ensure more than two-thirds of passenger cars and light trucks sold by 2032 are electric or hybrid vehicles. The EPA rule imposes strict limits on tailpipe pollution, limits the agency says can be met if 56% of new vehicles sold in the US are electric by eight years from now, along with 13% that are plug-in hybrids or other partially electric cars. That would be a huge increase over current EV sales, which rose to 7.6% of new vehicle sales last year, up from 5.8% in 2022. [...] The new rule slows implementation of stricter pollution standards from 2027 through 2029, before ramping up to near the level the EPA preferred by 2032. "Personal car ownership is about to get A LOT more expensive as it will have to carry the costs of deep discounts to entice EV sales," adds Slashdot reader sinij.

After securing billions in federal grants and loans, Reuters reports that the company is "planning a $100-billion spending spree across four U.S. states" to build and expand its chip manufacturing factories. From the report: The centerpiece of Intel's five-year spending plan is turning empty fields near Columbus, Ohio, into what CEO Pat Gelsinger described to reporters on Tuesday as "the largest AI chip manufacturing site in the world," starting as soon as 2027. Intel's plan will also involve revamping sites in New Mexico and Oregon and expanding operations in Arizona, where longtime rival Taiwan Semiconductor Manufacturing Co is also building a massive factory that it hopes will receive funding from President Joe Biden's push to bring advanced semiconductor manufacturing back to the United States. [...]

Gelsinger said about 30% of the $100-billion plan will be spent on construction costs such as labor, piping and concrete. The remaining will go towards buying chipmaking tools from firms such as ASML, Tokyo Electron, Applied Materials and KLA, among others. Those tools will help bring the Ohio site online by 2027 or 2028, though Gelsinger warned the timeline could slip if the chip market takes a dive. Beyond grants and loans, Intel plans to make most of the purchases from its existing cash flows.

"It will still take three to five years for Intel to become a serious player in the foundry market" for cutting-edge chips, said Kinngai Chan, an analyst at Summit Insights. However, he warned more investment would be needed before Intel could overtake TSMC, adding that the Taiwanese firm could remain the leader for "some time to come." Gelsinger has previously said a second round of U.S. funding for chip factories would likely be needed to re-establish the U.S. as a leader in semiconductor manufacturing, which he reiterated on Tuesday. "It took us three-plus decades to lose this industry. It's not going to come back in three to five years of CHIPS Act" funding, said Gelsinger, who referred to the low-interest-rate funding as "smart capital."

Major U.S. broadband internet providers must start displaying information similar to nutrition labels on food products to help consumers shop for services starting on April 10, under new rules from the Federal Communications Commission. From a report: Verizon Communications said it will begin providing the labels on Wednesday. The FCC first moved to mandate the labels in 2022. Smaller providers will be required to provide labels starting in October. The rules require broadband providers to display, at the point of sale, labels that show prices, speeds, fees and data allowances for both wireless and wired products. Verizon Chief Customer Experience Officer Brian Higgins said in an interview the labels will help consumers make "an equal comparison" between product offerings, speeds and fees.

Higgins said standardized labels across the industry "make it easier for customers to do a comparison of which provider is going to be the best fit for their needs." He said customers will still need to research various bundling offers across carriers. The labels were first unveiled as a voluntary program in 2016. Congress ordered the FCC to mandate them under the 2021 infrastructure law. "Consumers will finally get information they can use to comparison shop, avoid junk fees, and make informed choices about which high-speed internet service is the best fit for their needs and budget," FCC Chair Jessica Rosenworcel said.

The White House said Wednesday Intel has been awarded up to $8.5 billion in CHIPS Act funding, as the Biden administration ramps up its effort to bring semiconductor manufacturing to U.S. soil. From a report: Intel could receive an additional $11 billion in loans from the CHIPS and Science Act, which was passed in 2022. The awards will be announced by President Joe Biden in Arizona on Wednesday. The money will help "leading-edge semiconductors made in the United States" keep "America in the driver's seat of innovation," U.S. Secretary of Commerce Gina Raimondo said on a call with reporters. Intel and the White House said their agreement is nonbinding and preliminary and could change.

Intel has long been a stalwart of the U.S. semiconductor industry, developing chips that power many of the world's PCs and data center servers. However, the company has been eclipsed in revenue by Nvidia, which leads in artificial intelligence chips, and has been surpassed in market cap by rival AMD and mobile phone chipmaker Qualcomm.

An anonymous reader quotes a report from Ars Technica: The Biden administration on Tuesday warned the nation's governors that drinking water and wastewater utilities in their states are facing "disabling cyberattacks" by hostile foreign nations that are targeting mission-critical plant operations. "Disabling cyberattacks are striking water and wastewater systems throughout the United States," Jake Sullivan, assistant to the President for National Security Affairs, and Michael S. Regan, administrator of the Environmental Protection Agency, wrote in a letter. "These attacks have the potential to disrupt the critical lifeline of clean and safe drinking water, as well as impose significant costs on affected communities." [...]

"Drinking water and wastewater systems are an attractive target for cyberattacks because they are a lifeline critical infrastructure sector but often lack the resources and technical capacity to adopt rigorous cybersecurity practices," Sullivan and Regan wrote in Tuesday's letter. They went on to urge all water facilities to follow basic security measures such as resetting default passwords and keeping software updated. They linked to this list of additional actions, published by CISA and guidance and tools jointly provided by CISA and the EPA. They went on to provide a list of cybersecurity resources available from private sector companies.

The letter extended an invitation for secretaries of each state's governor to attend a meeting to discuss better securing the water sector's critical infrastructure. It also announced that the EPA is forming a Water Sector Cybersecurity Task Force to identify vulnerabilities in water systems. The virtual meeting will take place on Thursday. "EPA and NSC take these threats very seriously and will continue to partner with state environmental, health, and homeland security leaders to address the pervasive and challenging risk of cyberattacks on water systems," Regan said in a separate statement.

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.
