What happened

Boulder County’s planning office has reversed its 2024 termination of the controversial Lyons CEMEX cement plant’s right to operate, throwing a lifeline to one of Colorado’s three cement manufacturers while infuriating neighbors and environmental advocates…

Why it matters

Boulder County Community Planning and Permitting Director Dale Case on Tuesday rescinded a previous county notice of termination to CEMEX, saying that previous studies had overstated truck traffic to and from the plant on Colorado 66.

Common ground

The county’s 2024 termination had ruled that increases in CEMEX traffic violated nonconforming use provisions in its land use permit.
