Some tense moments late yesterday (Thurs.) in Spirit Lake. Spirit Lake Fire Chief Pat Daly says some residents had to be evacuated from their homes and the area cordoned off after crews working on the Erie Avenue project accidentally severed a natural gas main in the area of 20th Street and Erie Avenue. "We got the call about 4:45. They hit about a six inch main. The gas company was there, they were trying to figure out how to get it patched. They didn't have the stuff for the six inch so we waited there like two hours and then they were bringing in a crew from Council Bluffs. They left Council Bluffs at 9:00 last night and were supposed to be three to fours to get here then they were going to fix it." Daly says the main had about 700 to 800 pounds of pressure in it, causing a lot of gas to leak into the air. Fortunately he says there no extenuating circumstances that could have cause something really bad to happen.
