Winona will become the first city in Minnesota to monitor frack sand and diesel emissions along a truck route when two new monitors begin operations soon.
Two monitors have been installed on the roof of the Family YMCA building and are calibrating. The equipment is expected to begin registering data sometime this week.
The data will be collected for a year and will be used as a baseline of how much frack sand and diesel emissions are in the air along one of the busiest truck routes in the city from trucks coming off the interstate bridge.
The Minnesota Pollution Control Agency paid for the monitors, which cost about $60,000.
