Environmental Restoration
Cemex is committed to maintaining good stewardship of the San Joaquin River, wildlife, and surrounding lands.
Protecting Local Habitat and Wildlife
The CEMEX Rockfield Modification Project proposes updating the Reclamation Plan, which serves as a blueprint for restoring land that is no longer mined to open space, even as mining operations continue elsewhere on the property. The plan will restore 470 acres of open space, including riparian zones, ponds, lakes, trails, and native vegetation, supporting local wildlife, habitats, and outdoor activities.
The project also aligns with the San Joaquin River Parkway Master Plan, which envisions natural habitat and wildlife coexisting with mining operators. There will be no mining in the San Joaquin River or along its banks, nor does the project permit it. Moreover, the project does not limit existing access to the Parkway or river and in fact proposes potential easements that could extend the existing trail system around the quarry.
The CEMEX Rockfield Modification Project calls for updating the reclamation of both the Plant Site and the Quarry Site. Such plans serve as an environmental blueprint for how the sites will be restored when the supply of aggregate is depleted.
This transition will occur in stages.
Stage 1
In approximately 30 years, the processing operations will move from the Plant Site to the Quarry Site.
Stage 2
The old Plant Site will be graded, and the area surrounding the reclaimed pond will be planted with native vegetation to benefit local wildlife and enhance the habitat.
Stage 3
Even while mining is actively underway, the Quarry Site will be similarly graded and reclaimed once its aggregates reserves are depleted.
WHC Certification
The Rockfield facility has received annual WHC Certification® from Tandem Global (formerly Wildlife Habitat Council). WHC Certification is the world’s leading voluntary sustainability standard designed for broad-based biodiversity enhancement and conservation education activities on corporate landholdings, with certified programs in 47 U.S. states and 19 countries.
