At first, teachers at Sky Valley Education Center simply evacuated students and used fans to clear the air when the fluorescent lights caught fire or smoked with noxious fumes. When black oil dripped onto desks and floors, they caught leaks with a bucket and duct-taped oil-stained carpets.Then came the tests that confirmed their suspicions about the light ballasts.“Sure enough ... it was PCB oil,” said Cynthia Yost, who was among teachers who sent pieces of carpet and classroom air filters to a lab. Tests found elevated levels of the toxic chemicals, used as coolant in the decades-old ballasts that regulated electrical current to the lamps.Millions of fluorescent light ballasts containing PCBs probably remain in schools and day care centers across the U.S. four decades after the chemicals were banned over concerns that they could cause cancer and other illnesses. Many older buildings also have caulk, ceiling tiles, floor adhesives and paint made with PCBs, which sometimes have been found at levels far higher than allowed by law.Yet the Environmental Protection Agency has not attempted to determine the scope of PCB contamination or assess potential health risks, in large part because of lack of funding, political pressure and pushback from industry and education groups, according to dozens of interviews and thousands of pages of documents examined by The Associated Press.Members of Congress who promised three years ago to find money to help address PCBs and other environmental problems in the nation’s schools never introduced legislation.And an EPA rule that would have required schools and day cares to remove PCB-containing ballasts moved slowly under the Obama administration, then was quashed by President Donald Trump within days of his inauguration.That was the final straw for Tom Simons, a former EPA regulator who worked for years on the rule and said getting rid of ballasts was the least the EPA could do to protect children.“We thought it was a no-brainer: There are millions out there. These things are smoking and dripping, so let’s put this through,” said Simons, who retired shortly after Trump took office.___For decades, the presence of PCBs in schools flew under the radar.States, cities and environmental agencies focused on removing them from lakes, rivers and toxic waste sites because most exposure to PCBs is believed to come from people’s diet, including fish from contaminated waterways, and because PCBs do not break down easily. Studies have linked them to increased long-term risk of cancer, immune and reproductive system impairment and learning problems.PCBs, or polychlorinated biphenyls, are mixtures of compounds manufactured by Monsanto Co. and widely used as coolants and lubricants in electrical equipment until they were banned in 1979.By then they were in transformers, air conditioners, adhesives, carbonless copy paper and billions of fluorescent light ballasts in schools, hospitals, homes, offices and commercial and industrial buildings. They also were ubiquitous in the environment and building up in human bodies.Nobody worried about schools.Then a 2004 study by Harvard health professor Robert Herrick identified the widespread use of PCBs as a plasticizer in caulk in schools built before 1980, estimating that as many as 14 million students and 26,000 schools could be affected. The EPA had not been aware of its use in caulk before then, Simons said.The EPA later found that the chemicals can move from building materials into the air and dust, where they can be inhaled or ingested. They also can be absorbed by walls and other surfaces as an ongoing source of exposure.Regulators also discovered that old fluorescent light ballasts remained a potentially widespread source of PCB contamination. The EPA had allowed the ballasts to remain in use because chemicals were in enclosed capacitors that experts thought would last only about 12 years. But it turns out they can last a half century or longer, said Simons.The older they are, the more likely ballasts will leak, catch fire or smoke. And that has happened repeatedly in schools, office buildings, restaurants and factories in recent years, according to reports reviewed by the AP.But the EPA has mostly voluntary guidelines, including recommended indoor air limits for PCBs that it says should protect children from health problems.The agency does not require — or encourage — schools to test for PCBs, so few do. If they are found in materials such as caulk, schools could be forced to undertake expensive cleanups when many are struggling to keep basic infrastructure intact and meet educational needs. Drawing attention to the issue also risks alarming parents.PCBs are illegal in building materials in concentrations exceeding 50 parts per million — a threshold set by the EPA decades ago based on how much contaminated material could affordably be removed rather than health risks.Rather than fostering “a very confusing and fearful situation,” the EPA should recommend that schools test classroom air for PCBs, then identify and address specific sources if the results are elevated, said Keri Hornbuckle, a civil and environmental engineering professor at the University of Iowa and one of the nation’s top researchers of PCBs in schools.“There is a good reason PCBs were banned, so ... let’s remove the worst cases and where (kids) are most vulnerable and have the highest exposure,” she said. “But you have to have the data.”Whether PCBs are addressed often is determined by ZIP code.In California’s wealthy Santa Monica-Malibu School District, parents, including model Cindy Crawford, sued to force the district to address PCBs after tests of caulk found levels up to 11,000 times the 50 ppm threshold. The district ultimately agreed to get rid of PCBs. It has torn down a middle school and continues to remove them from other buildings.In Hartford, Connecticut, the ending was far different. John C. Clark Elementary and Middle School, in a largely low-income African American neighborhood, was permanently closed in 2015 after PCBs were found and the city could not afford to remove them. The city has sued Monsanto and a company that manufactured caulk to recover the costs.“It was the crown jewel of the neighborhood,” Steven Harris, a former city council member and grandfather, said as he walked the deserted school grounds. “Our school board is doing the best they can. The reality is we don’t have a lot of money. And it’s going to take money to fix this problem.”Monsanto, now owned by Bayer Crop Sciences, has denied responsibility in lawsuits involving several school districts, saying it did not manufacture the building materials or components that contained PCBs.Concerns over schools like Hartford’s are one of the issues that ultimately kept the EPA from taking stronger steps to address PCBs.The agency, which originally recommended that schools test for the chemicals, was warned by the Association of California School Administrators that forcing schools to remove PCBs could create “a civil rights issue” if low-income minority schools could not afford it. What’s more, many of those schools have other environmental problems — including lead, asbestos and mold — that could be higher priorities.So instead, the EPA developed guidance that promotes vigilant cleaning and better ventilation and suggests schools could cover materials suspected of containing PCBs until the buildings are renovated or razed.But the recommendations were released quietly on the agency website to avoid publicity that might frighten the public, according to former EPA officials who said the agency was hamstrung by a problem that could cost billions of dollars. There are no rules requiring school officials to tell parents if they find or suspect their buildings have PCBs.Judith Enck, administrator of the EPA’s Region 2 under Obama, said the EPA bowed to intense political pressure.“The debate was never based on science and health. It was ‘We don’t want the grief from schools, and it’s a lot of work and we have other priorities,’” said Enck, who led an effort to get ballasts out of New York City schools. “I disagreed.”A bill introduced in 2010 by three New York congressmen aimed at funding school PCB cleanups was withdrawn after New York City officials agreed to replace aging ballasts.

Britain's exit from the European Union will happen and should happen, President Donald Trump said Tuesday during a news conference alongside outgoing UK Prime Minister Theresa May.Praising his British counterpart as doing a good job in handling Brexit, Trump said the planned divorce would be good for the UK."It wants to have its own borders. It wants to run its own affairs. This is a very, very special place, and I think it deserves a special place," Trump said.The President also described a pair of British politicians as "negative."Asked about Labour Party leader Jeremy Corbyn, Trump at first seemed to misunderstand, launching into an attack on London Mayor Sadiq Khan.Trump said the London mayor "should be positive, not negative.""He's a negative force, not a positive force," Trump said. "I think he should focus on his job."Asked again to respond to Corbyn, who spoke at a demonstration earlier in the day, Trump said he declined a meeting request from the opposition leader."He wanted to meet today or tomorrow," Trump said. "I decided I would not do that."He said he believed Corbyn to be "somewhat of a negative force."Trump is visiting Whitehall at a difficult moment. May is stepping down as head of her party at the end of the week, entering a lame duck period as the conservatives select a new leader. In some ways, her talks with Trump will be purely symbolic since she'll soon hand over her myriad troubles, principally the Brexit matter, to a successor.But White House and British officials have maintained the talks will be substantive, given the general continuity in UK foreign policy between prime ministers and the long list of shared concerns between the two countries.That includes Iran, which the UK still hopes will adhere to the Obama-era nuclear deal that Trump scrapped, and the Chinese telecom giant Huawei, which the US is working to prevent from establishing 5G networks in Europe and elsewhere.However much Trump has warmed to May, he's been far warmer toward two of her vocal critics: Boris Johnson, a former mayor of London who once served in May's cabinet before resigning in protest; and Nigel Farage, a Brexit campaigner who makes semi-regular appearances on Fox News.Trump phoned Johnson on Tuesday and offered a one-to-one meeting with the former London mayor, a British official told CNN's Pamela Brown.The 20-minute phone call was friendly and productive, the official said.Johnson thanked the President for the invitation, but declined the meeting to focus on a political event that was happening at the same time, the official said. The President understood.Johnson, a contender to replace May as prime minister, said he looked forward to catching up at a later date.A day of stately ceremony and ungenerous feuding behind him, Trump moved on to the business of transatlantic diplomacy on Tuesday with meetings focused on trade, security and Britain's pained exit from the European Union.Trump's royal engagements with Queen Elizabeth II, the centerpiece of his state visit here, are over, and for a short span midday his host will be the beleaguered Prime Minister Theresa May, with whom he will sit for group talks alongside other aides before convening a joint news conference.Trump and May started the day jointly hosting a breakfast of business chiefs at the Tudor-era St. James's Palace, joined by the President's daughter and senior adviser Ivanka Trump and a dozen or so executives from American and British firms.At the start of the session, Trump said it had been an "honor" working with his British counterpart and joked she should delay her departure as prime minister until a new trade deal is struck."It's an honor to have worked with you," Trump told May. "Stick around. Let's do this deal."The US President will later tour the underground warren of rooms from which Winston Churchill ran his war efforts, a paean to a British leader Trump has long revered and hoped to emulate, at least in photographs.Instead of taking his armored motorcade from point to point in London this week, Trump has relied on his Marine One helicopter -- even for short distances -- avoiding protests on the city's streets. London Mayor Sadiq Khan, who Trump insulted on Twitter as he was landing at Stansted Airport on Monday, has allowed demonstrators to fly a giant balloon depicting Trump as a baby in a diaper.Only small gatherings materialized on Monday, but larger protests were expected on Tuesday. The Labour leader Jeremy Corbyn was expected to address one of the demonstrations.Watch the full press conference below: 4582
