SIOUX CITY, Iowa (AP) — Federal officials say BNSF railroad has agreed to clean up 2 million pounds of broken glass from televisions and computer monitors that contains lead at a property it bought in Sioux City, Iowa, several years ago. The Environmental Protection Agency says the glass from cathode ray tube monitors was left at the site by a recycling company that owned the land before BNSF bought it in 2014.

The EPA says the cleanup will take about four months to complete. The EPA says the Sioux City site is one of six locations in Iowa and Nebraska where Recycletronics left roughly 16.9 million pounds of glass from CRT monitors behind.
