The U.S. Environmental Protection Agency says toxic waste emissions have gone up in the U.S. Virgin Islands but dropped across Puerto Rico.
The agency says four facilities in the U.S. Virgin Islands released nearly 763,000 pounds (346,000 kilograms) of waste last year. It blamed the 13 percent increase on air and water emissions from the state-owned water and power company and on the Hovensa oil refinery on the island of St. Croix.
The EPA said Thursday that 115 facilities in Puerto Rico released nearly 5,290,000 pounds (2.4 million kilograms) of waste in 2010. The EPA noted that the 15 percent drop in emissions in Puerto Rico is attributed in part to an oil refinery closure.
