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.

An autopsy is expected to be performed Wednesday on the 23-month-old girl who was reportedly abducted in Pennsylvania over the weekend and later found dead, a district attorney said.Nalani Johnson was reportedly taken Saturday. Her body was found Tuesday in a Pennsylvania park. Authorities hope that an autopsy can provide some clues about what happened to the toddler in between."Until we have some more information regarding the cause and manner of death, we really can't give you much at this point," Indiana County District Attorney Patrick Dougherty said at a news conference Tuesday.Nalani's father, Paul Johnson, says that a woman he was involved with drove off with his daughter Saturday after an argument, according to a criminal complaint filed by Allegheny County police. That woman, Sharena Nancy, has been charged with the kidnapping of a minor, interference with custody of children and concealment of whereabouts of a child.Nancy, 25, is being held without bail at the Allegheny County Jail, and her preliminary hearing is scheduled for September 16.CNN hasn't been able to identify or reach an attorney for Nancy.Her father's storyJohnson and Nancy were at the start of an "intermittent romantic relationship" that began over social media a few months prior to the incident, Allegheny County Police Superintendent Coleman McDonough said a news conference earlier on Tuesday.Johnson said he, his daughter and a friend spent several hours with Nancy the day that Nalani was reportedly abducted, according to the criminal complaint. Nancy was driving them all in a car when an argument ensued, the complaint said.Johnson said he got out of the car, but when he went to get his daughter from the car seat, Nancy drove off with her, the complaint said.Johnson told detectives he tried calling Nancy's cellphone multiple times, but she never picked up, so he called 911 around 5 p.m. ET, the complaint said.Police stopped Nancy's car around 7:30 p.m. but did not find Nalani inside, according to the complaint. Nancy was arrested during that stop.Johnson told police that the car Nancy was driving had Uber and Lyft stickers on it. Representatives of Uber did not immediately respond to CNN's request for comment.Dana Davis, a communications manager for Lyft, told CNN that while this incident did not happen on the Lyft platform, they have banned Nancy from driving with Lyft, adding that the allegations were "deeply disturbing."Her alleged kidnapper's storyNancy's version of events, detailed in the complaint, differs from Johnson's.She told authorities that Johnson sold the little girl for ,000 and that she was completing the drop off, the complaint said.Johnson showed her a picture of a black woman she was supposed to meet about 20 minutes from a gas station in Monroeville along US Route 22 with Nalani, according to the complaint.Nancy told detectives, the complaint said, that she encountered a silver SUV with out-of-state license plates parked on the side of the road and did as she had been instructed, passing the toddler and the car seat over to a woman standing next to the car and then driving off. Nancy told police she saw a second woman inside the SUV, the complaint said.Nancy said she then drove around, smoked cigarettes and talked on the phone with her husband, the complaint said.McDonough said Tuesday they have no evidence to corroborate Nancy's version of events, adding that Johnson and his family have been cooperative with the ongoing investigation. 3509

Barstool Sports founder Dave Portnoy made it clear he has no interest in seeing his employees unionize. On Monday, Portnoy threatened to fire any employee who makes contact with a writer for Live Science about information on unionizing. In a tweet on Monday, Portnoy wrote, "If you work for @barstoolsports and DM this man I will fire you on the spot." This tweet was in response to a tweet from Rafi Letzter who wrote, "If you work for Barstool and want to have a private chat about the unionization process, how little power your boss has to stop you, and how you can leverage that power to make your life better: my DMs are open."According to the National Labor Relations Board, Portnoy's tweet could potentially break labor regulations. One of the examples the labor board lists for potential violations of the law is, "Threatening employees with loss of jobs or benefits if they join or vote for a union or engage in protected concerted activity."Portnoy's tweet has also drawn backlash from Democratic Rep. Alexandria Ocasio-Cortez. She responded to Portnoy's tweet. "If you’re a boss tweeting firing threats to employees trying to unionize, you are likely breaking the law &can be sued,in your words, 'on the spot.' ALL workers in the US have the protected freedom to organize for better conditions," she tweeted.The exchange between Portnoy and Ocasio-Cortez even drew the attention from Donald Trump Jr. Picking a fight with 1450

BLOOMINGTON, Minnesota — A family visiting the Mall of America last week has since been spending time at the Children's Minnesota Hospital with its 5-year-old son, who is recovering after being the randomly chosen victim of a heinous crime.Police said a man unknown to the family grabbed the 5-year-old boy and threw him over the third-floor balcony inside the mall, allowing him to forcefully fall 40 feet to the ground.The child survived and is undergoing intensive health care — he has been hospitalized since the incident April 12.The man who has admitted to harming the boy is 24-year-old Emmanuel Deshawn Aranda, who said he had been looking for someone to kill. He told police he was tired of being rejected by women at the mall and this act was out of that anger.The child's mom told authorities at the scene the family was outside of the Rainforest Cafe when Aranda approached them and picked up the child without warning.The man had already been banned from the Mall of America in his past: He was twice convicted in 2015 for assaults he committed at the shopping center.Aranda is charged with attempted homicide.A 1142
