By Mary Ellen Podmolik | A former president and business manager of the International Union of Operating Engineers Local 150 was charged Monday with violating federal labor law for actions involving his buffalo farm in Maryland.

William E. Dugan, 76, formerly of Mount Prospect and now of Hancock, Md., was charged with a misdemeanor in U.S. District Court in Chicago for allegedly demanding and accepting in April 2005 livestock feeders valued at more than $900 for his farm from a company that employed Local 150’s members. The company is not identified in court documents.

Dugan is scheduled to appear for arraignment at a later date.
