Using the Harbor Maintenance Trust Fund for its intended purpose will end the dredging crisis on the Great Lakes declared a stone shipper at a briefing for the Great Lakes delegation in Washington, DC on April 2 hosted by Great Lakes Maritime Task Force. “We need approximately $200m to clear the dredging backlog on the Great Lakes,” said Thomas Buck, President and Chief Executive Officer of Carmeuse Lime & Stone. “The fund collects $1.1b annually, but only spends $700m. That leaves a surplus of nearly $5b. Carmeuse Lime & Stone operates three large stone quarries that ship via the Great Lakes. In 2008, those quarries loaded 14 million tons of aggregate and fluxstone into Great Lakes freighters.
