The Winona City Council Monday approved 3 of the 4 ordinances to the city's frac sand moratorium that's set to expire in March.

The council unanimously approved air quality monitoring, moisture testing and setbacks from residential properties but failed to agree on proposed language for a transportation impact analysis.

3rd Ward Council member Pam Eyden says she supports requiring an analysis on any operation with over 20% of the traffic on local streets not letting the city engineer decide if one's needed.

When asked if the ordinance might have a negative effect on vehicles being allowed to use designated truck routes, Assistant Assistant City Planner Carlos Espinosa said that it would only trigger a traffic study.

The ordinance was tabled and will be brought back in two weeks to the next council meeting.            

The three ordinances that passed include increasing the setback from any sand mining activities to a structure from 1,000 feet to 2,000 feet, mositure testing level would be increased from 1.5% to 2.5% to better decrease blowing sand and cutting the hours of mining operations from 6:00 a.m. to 10:00 p.m. to 6:00 a.m. to 9:00 p.m.
