surfaces throughout the entire Rose Red Quarry. Simply put, drilled and blasted <br /> rock will have minimal movement during blasting and a lack of fail-able material <br /> and void space beneath the blast zone precludes dynamic loading from occurring <br /> onsite. However, slope stability analysis for the surface quarry operation is <br /> discussed on page 5 of the report"Geotechnical Analysis of the Colorado Rose <br /> Red Granite Quarry" dated November 2018. <br /> c. DRMS Response 4: The Division is currently reviewing the Geotechnical <br /> Analysis. If Additional adequacy review issues are identified, they will be <br /> forwarded to you as soon as possible.
