(Story courtesy of Edmunds AutoObserver ) Reports of details in the new tentative four-year labor agreement between General Motors Co. and the United Auto Workers union indicate provisions of the proposed contract include a commitment from GM to reopen its Spring Hill, TN, assembly plant. The Spring Hill site, originally built to assemble vehicles exclusively for GM’s now-defunct Saturn division, was mothballed in late 2009 as GM was executing a massive restructuring.

Reports from Detroit, unconfirmed by GM, cite sources as saying the restarted Spring Hill plant will build a new vehicle and also engage in supplemental production for in-demand vehicles. The plant last built the Chevrolet Traverse fullsize crossover, assisting in production with the Traverse’s “home” plant in Lansing, MI. It is not yet known when the plant would be restarted, but it likely would be staffed with a mix of new and veteran workers. The UAW rank-and-file membership still must approve the tentative contract, which would be in effect until fall of 2015.
