MADISON — Effective Oct. 1, Hancock Lumber began the “indefinite curtailment of production at the company’s Madison Lumber Mill location and consolidation of that business into its Casco, Bethel, and Pittsfield mill operations,” according to a statement issued by the company on Wednesday. Erin Plummer, chief marketing officer for Hancock Lumber, said the Madison log yard will remain open to help support the procurement of eastern white pine. “This decision is in response to site-specific challenges and changing market conditions,” said Plummer, based out of the Hancock’s Casco, Maine office. She said “Hancock Lumber remains committed to the forest products industry as it has since 1848.” Hancock purchased Madison Lumber in October 2022. A source emailed the Sun on Wednesday, saying that “they have completely shut down the sawmill.”
