Lehigh Hanson will permanently shut down the cement plant at its Permanente complex, located west of Cupertino, Calif., reported local media.
The facility has not operated its cement kiln since April 2020, but will continue other ongoing operations, such as material distribution, as long-term strategies for the property are evaluated.
Although the cement plant has made many valuable contributions to the region since opening in 1958, it has recently been a source of controversy. In the past decade, the plant has reportedly received more than 2,100 environmental violations, with more than 100 considered serious, local media stated.
Lehigh plans to develop and submit a new reclamation plan amendment application to Santa Clara County, which has land use regulatory authority over the site.
