BLAIR – Nearly a block long line of flashing lights on the south side of the Washington County Court House at this time. Dispatch staff are evacuating as a safety measure. Dispatch operations will be handled by Omaha during the interim. A natural gas leak was detected earlier this evening, and narrowed down to the berm area of the annex and parking lot. Blair Fire and Rescue, Black Hills Energy, and City of Blair personnel are working on locating the gas line, digging up and repairing the leak at this moment. Please avoid South Street from 16th to 15th.
