A commercial waste company has agreed to spend $252,000 removing chemical waste from 60 schools in Massachusetts and Rhode Island to settle claims that it violated hazardous waste rules. The Environmental Protection Agency had accused Northland Environmental of violating federal and state environmental rules by not properly identifying and storing hazardous chemicals. To settle the claim, the company has agreed to remove outdated and unwanted chemicals from the schools for free. The company will also purchase safety equipment for school science labs. The schools are all within 50 miles of Northland’s Providence facility. The company also agreed to pay a $58,278 fine. The EPA said Northland quickly fixed the problems at its facility once they were identified. The company did not immediately respond to a message.
