In the wake of  Lehigh Hanson’s announcement last year that it was ending cement production at its quarry west of Cupertino, Santa Clara County is looking to make the decision to permanently end the nearly-century-old cement kiln’s operations legally binding.

Lehigh, which has played a large role in construction projects across the Bay Area since 1939, has been a point of contention in recent years as residents and environmentalists have spoken out with concerns about the noise and pollution emitted from the plant.
