Cemex challenges termination of Lyons plant operations

Cemex has contested Boulder County’s decision to terminate its right to operate the Lyons cement plant and is calling for the decision to be reversed, citing ‘significant’ implications for the state and local employment. The dispute follows a notice from the Boulder Country Community Planning office in April 2024, attributing increased traffic as the primary reason for the termination. The county and the Colorado Department of Transportation began investigating the plant in 2022, after residents of the area complained.

Cemex stated in its response to Boulder County “The Department’s conclusion did not take into account the historical trucking of material to and from the Lyons cement plant, relying instead on a study Cemex voluntarily undertook for the Colorado Department of Transportation for a different purpose, and that considered only three days of traffic data in each of two consecutive years. The determination also failed to apply applicable precedent that a nonconforming use does not terminate when traffic occurring off-site changes.”

The Community Planning and Permitting Director will now review the additional evidence brought forth by Cemex and issue an additional determination. Depending on the outcome, Cemex will have the option to appeal the decision to the Boulder County Board of Commissioners. The closing of the Lyons plant would lead to the loss of 100 jobs and only two cement plants remaining in Colorado.
