The city of Mankato has again suspended the explosives permit for Jordan Sands, after blasting sent rocks outside of its Jefferson Quarry.
The Department of Public Safety says staff were in the quarry Tuesday morning conducting a routine inspection, when rocks up to a foot in diameter left the quarry property during blasting. Damage was reported to the siding of a home on Harper Street and a tree.
The Jefferson Quarry explosives permit was immediately suspended pending an investigation into the cause of debris on private property.
Jordan Sands representatives arrived at Jefferson Quarry to evaluate and determine damage extent.
