SIOUX CITY, Iowa (AP) — Federal prosecutors for Iowa say a contractor who put workers at risk of exposure to asbestos has been sentenced to two years’ probation.

The U.S. Attorney’s Office for the Northern District of Iowa says 61-year-old Steven Weaver, of Algona, was sentenced Wednesday in Sioux City’s federal courthouse after pleading guilty in October to one count of violating clean air work practice standards.

Prosecutors say Weaver admitted he was an experienced contractor and building inspector who failed to thoroughly inspect for asbestos before beginning a renovation of a former Kossuth County Home he had bought in 2013.

When the Environmental Protection Agency discovered piping in the basement contained asbestos, it instructed Weaver to report to the Iowa Department of Natural Resources. But Weaver didn’t and continued the renovation in late 2014.

Weaver was also fined $10,000 and ordered to pay nearly $1,600 in legal costs.
