(Radio Iowa) – The Marengo company that was the site of an explosion and fire in December has complied with a judge’s order to give the Iowa Department of Natural Resources a list of chemicals present at the time. The Attorney General’s Office says C-6-Zero attempted to submit the list by the deadline but the company was delayed by technical issues. The A-G’s Office says it has obtained the list Friday and had passed it to the D-N-R.
