How many jobs will be created by Sargent Quarry?
There will be 15 to 20 full-time employees at the Sargent Quarry site during full operation. In addition to direct employment, when considering the multiplier effect that occurs with a project of this type, Sargent Quarry will contribute to the creation of more than 200 local and regional jobs.
What will the impacts be from dust?
Every mining operation creates some amount of fugitive dust emissions associated with extraction and processing the mineral resource. Sargent Quarry will use the latest state-of-the-art best available control technology (BACT) to suppress, capture, and minimize potential fugitive dust emissions. Modern control technologies substantially reduce dust emissions and the all stationary onsite dust generation sources would be permitted and monitoring by the Bay Area Air Quality Management District (BAAQMD). An air quality impact analysis has been conducted for operations and determined that no significant environmental or health effects would be caused by the potential residual dust emissions that may be generated during project operations.
Will the project be seen from Highway 101?
Before mining begins at the Project site, a berm will be constructed along the east side of the site parallel to Highway 101 to screen views of processing plant facilities from Highway 101. Although processing facilities could still be visible from a few limited areas, any such visibility would be minimal.
What is the source of water for Sargent Quarry?
Sargent Quarry will utilize groundwater obtained from an existing on-site well for process water (rinsing and washing material) and dust control. At the plant site, 80 percent of the water used for processing will be recycled and reused with only 20 lost to evaporation and outgoing product.
What is included in the Reclamation Plan?
- 259 acres of annual grasslands would be created, providing California red-legged frog and California tiger salamander estivation habitat, burrowing owl habitat, American badger habitat;
- 47 acres of oak woodland would be created within portions of the annual grasslands, providing nesting, roosting, and foraging habitat for many common and special‐status bird species;
- 91 acres of coastal sage scrub and chaparral habitat would be created within portions of the annual grasslands, providing nesting, roosting, and foraging habitat for special‐status bird species and other animals;
- 1 acre of seasonal wetlands providing known California red-legged frog breeding habitat; and potential California tiger salamander breeding habitat; and,
- Over 11,000 linear feet of streams draining to both Sargent and Pescadero Creeks.
