Lehigh Southwest Cement Plant & Permanente Quarry Public Meeting

Santa Clara County Supervisor Joe Simitian held the annual Lehigh Southwest Cement Plant and Permanente Quarry Public Meeting with various oversight agencies at the Cupertino Community Hall on Wednesday, March 27.

Upon returning to the Board of Supervisors in 2013, Supervisor Simitian asked the County to step up its oversight role of the site by increasing on-site inspections and organized annual coordination meetings involving local, state, and federal agencies with jurisdiction over Lehigh operations. This annual public meeting is held as part of this ongoing effort. 

Oversight agencies participating this year included: City of Cupertino, Santa Clara Valley Water District (Valley Water), Bay Area Air Quality Management District, San Francisco Bay Regional Water Quality Control Board, and Santa Clara County’s County Counsel, Department of Environmental Health, and Department of Planning and Development.

Thanks to the City of Cupertino for hosting.
