A contractor building the town’s wind turbine has been cited by the Occupational Safety and Health Administration for two alleged violations. Lumus Construction Inc. of Wilmington received two fines totaling $3,080, one because the agency said the size of the openings on a platform where workers stand on the tower was too wide and the other due to allegations of missing bolts on the turbine ladder. The contractor settled with OSHA for $2,420. The alleged violations were found when the safety organization investigated a December 2012 accident in which a worker fell 24 feet from the tower into the turbine. OSHA spokesman Andre Bowser said that accident, which the worker survived, triggered the investigation, but the fines were unrelated to it.
