A former Democratic political boss in East St. Louis is facing at least 15 more months in federal prison on environmental infractions -- on top of the 21 months he's already serving in a vote-fraud scheme.

Charles Powell Junior has pleaded guilty in US District Court in East St. Louis to a conspiracy charge and a charge of failing to notify authorities before removing asbestos.

Powell admitted he had been hired to renovate the Spivey Building in East St. Louis and that he had hired another man.

According to court documents, both men knew the building contained asbestos but improperly removed and disposed of asbestos-covered pipes and other asbestos-containing material in 2002. Powell once headed East St. Louis' Democratic Party.
