State utility regulators will investige whether the contractor that caused a fatal explosion in downtown Sun Prairie last summer broke state law.
The Public Service Commission’s investigation will ask if V-C Tech broke state law — by not calling Digger’s Hotline before starting to install fiber optic lines last July 10th.
The resulting explosion destroyed five buildings, damaged many others, and a killed firefighter. Federal regulators have already fined V-C Tech and Bear Communications. Sun Prairie police found there was no criminal wrongdoing.
