DNR Investigates Air Pollution Incidents At Wausau Factory

Officials at the 3-M Corporation factory say corrective steps have been implemented after pollution control devices at the Wausau location failed to operate for several hours in April.  D-N-R investigators are taking a closer look.  The Minnesota-based company also didn’t report emissions in 2016 and 2017, as it was supposed to.  A spokesperson says new equipment has been installed to keep the April incident from happening again.  Staff members have received additional training.
