Quarry Improvements

Quarry Improvements

CEMEX has developed a new Quarry Operations Plan that utilizes some of the best environmental and business practices.  New equipment has also been purchased in order to reduce fugitive dust and track-out (dirt) onto Mitchell Canyon Road. Since modifications are evolving and being tested, we welcome your feedback.

Dust Reduction

• In addition to reducing the size of several stockpiles, some stockpiles have been moved from the borders of Mitchell Canyon Road to the interior of the quarry yard.
• Timed sprinklers are used to water stockpiles which also operate on weekends, and water truck applications are more frequent during dry and windy conditions.
• A Fugitive Dust Control Plan has been implemented that includes employee training, monitoring, and application of dust control measures including dust suppressant for onsite roads.

Track-Out Reduction

• As of late 2019, all trucks are required to enter a new wheel wash in order to dislodge dirt and mud from trucks prior to accessing our truck scale and exiting the site. (Watch this wheel wash video.)
• Improved methods and frequency of street sweeping and began the use of a larger more effective sweeper in the first quarter of 2020.

Landscaping

• New landscaping added to the quarry entrance.

• Additional landscaping, trees and berms will be added along Mitchell Canyon Road to screen views of quarry operations and reduce dust and noise.
