The Minnesota Department of Transportation is making plans to remove and dispose of trees found in Olmsted County that are infected with the emerald ash borer.
MnDOT has confirmed an infestation found in trees located near Interstate 90 and Highway 63 south of Rochester.
That means Olmsted County will be joining Winona, Houston, Hennepin and Ramsey counties in a state and federal quarantine. The quarantine is in place to help prevent the E-A-B from spreading outside a known infested area into new areas.
It is designed to limit the movement of any items that may be infested with the bug, including ash trees and ash tree limbs, as well as all hardwood firewood.
Since the E-A-B is not very active this time of year, the tree removal will not take place until October.
