(CNN) -- Exxon Mobil will pay all of the costs related to last week's oil spill in an Arkansas neighborhood, a company spokesman said Wednesday. Between 3,500 and 5,000 barrels of heavy crude leaked from a ruptured pipeline -- not 12,000 barrels, as previously reported, according to Exxon Mobil spokesman Alan Jeffers. The company has no timeline yet for when the cleanup around the two dozen homes in a Mayflower, Arkansas, subdivision would be completed, Jeffers said. Excavation of the contaminated soil is under way, weather permitting, he said. He did not have an estimate of the costs of the effort.
