GOODLAND, Kan. (AP) — Crews from Black Hills Energy are fixing a ruptured gas line that forced evacuations of homes and businesses in downtown Goodland. Authorities were unable to say how many people remained out of their homes Wednesday night. The evacuation zone covered a few city blocks. The Sherman County Sheriff's Department said in a news release that some residents were allowed to return and the evacuation zone was adjusted about 90 minutes after the leak was discovered around 3 pm Wednesday. No fires, injuries or explosions were reported. The American Red Cross sent volunteers and food from Hays to shelter people overnight if necessary. The sheriff's office says the rupture was apparently caused by workers using a boring machine.
