What percentage of the Gravel being mined is silica? What are the particle size and concentration of fugitive dust that will be released into the surrounding neighborhood 600 yards away? Will there be dust monitoring on site? If so where will results be posted? Why didn't the city require the mining company follow the Boulder County fugitive dust best practices? https://www.bouldercounty.org/environment/healthy-home/dust-health-concerns/
Practices such as :
1. Apply water to ground prior to, during, and after earthmoving operations.
2. Clear vegetation only from areas you will work right away.
3. Avoid overloading haul vehicles; the freeboard should not be less than 3 inches high.
4. Empty loader slowly and while dumping keep the bucket close to the ground.
5. Add surface Gravel and apply water to haul roads
6. Post and enforce lower speed limits on haul roads (10-15mph)
And many more techniques.

The
city does not have information regarding the amount of silica dust.
Please reach out to the contact email for Aggregate as they have the technical
expertise to provide answers to these questions. The city does have conditions
of approval for the gravel mine operation which are located on sheet 3 of the
approved plan. Specifically, condition #11 requires the operator to cease
loading and hauling operations when sustained wind speeds reach 30 MPH or
higher. Condition #13 requires the operator to obtain permits from Public Works
that relate to construction activity and condtion #14 requires the operator to
comply with state fugitive dust standards. The site will be monitored and
inspected by both city Public Works inspectors as well as state mining
inspectors. Alternatively, residents can contact the city’s Code
Enforcement division at (303) 651-8695 to report a suspected violation of the
standards.
Do you know if this development will begin gravel mining this year? Can I be added to an update e-mail regarding this project?

It is the city’s understanding that Aggregate Industries plans to start the mining in 2020. At this time the city does not have a specific schedule from Aggregate. We would recommend you reach out to the email address for Aggregate directly at us-c-irwinthomasinfo@lafargeholcim.com and ask to be added to their email list for more specific information about their project and scheduling.
Is the information contained within the website the most current/up to date?
