US: The Board of County Commissioners of Boulder, Colorado, has denied Cemex USA’s application for a 15-year extension to its Dowe Flats quarry mining licence, following its expiry on 30 September 2022. Commissioner Claire Levy cited dust, traffic, noise and disturbances to wildlife as reasons behind the decision.
Cemex USA’s nearby Lyons cement plant has previously relied on the quarry for the supply of 760,000t/yr of limestone.
