A plant in Independence will be closing this spring. The Buchanan County Economic Development Office says L & M Radiator has been affected by the global downturn in the demand for mining equipment. The Minnesota-based company makes large heat exchange radiators for large equipment like oil rigs and mining dump trucks, with Caterpillar among its major customers. L & M began operations in Independence in 2005, with an expansion in 2011. At their peak a couple years ago, L & M employed about one-hundred twenty-five people locally. Employment levels have dropped over the last six months. Twenty-five employees will be affected by the shutdown in March, with possible job offers at other plants. Buchanan County Economic Development Executive Director Nate Clayberg says he’s optimistic that when the industry bounces back, L & M Radiator might consider re-opening the Independence plant.
