Claiming that county planners are stalling efforts to expand its surface mining activities, Lehigh Southwest Cement Company on Feb. 25 announced that it’s suing Santa Clara County for failing to process its application for expansion.

Lehigh in May 2019 submitted an application to amend its reclamation plan, approved by the county Board of Supervisors in 2012, to increase total mining production at its quarry in the Cupertino foothills by approximately 600,000 tons per year. The county accepted the application as complete in November 2019, but Lehigh’s complaint alleges that the county has failed to move forward in processing it.
