HAMMOND | A Griffith man has pleaded guilty to discharging pollution through the Hammond Sanitary District's water treatment works without a permit, the U.S. attorney announced Friday.
In November 2011, private company owner Ronald Holmes and company manager Stewart Roth were federally charged with illegally discharging wastewater into Hammond Sanitary District sewers from a closed facility, Hammond federal court records show.
Holmes, of Griffith, recently pleaded guilty to the felony pollution discharge count, prosecutors said. His sentencing is scheduled for March 14. Private company NH Environment Group Inc. also pleaded guilty to a misdemeanor count related to the case, federal prosecutors said in a prepared statement Friday.
Roth, the former manager of the Hammond Sanitary District, filed a plea agreement in federal court last year, admitting to violating the U.S. Clean Water Act, court records show. In the filing, Roth agreed to cooperate with federal authorities in other environmental investigations.
