8. Within Exhibit C,under the heading 6.3.3(I)(e),the application states there will be 3-6 pit excavations <br /> with access routes. The Exhibit E Mining Plan Map Detail 1 map also identifies a permit area roads, <br /> totaling 530 feet. Please discuss the construction and reclamation details of the access roads and <br /> provide the maximum width of the roads. <br /> Response: Please see attached revised Exhibit C, 6.3.3(1)(e). <br /> 9. Within Exhibit C, under the heading 6.3.3(1)(f),the application states the work area around the <br /> excavation will be benched to accommodate overburden.Please provide further details clarifying this <br /> statement.A cross-sectional diagram may be needed to depict the proposal. <br /> Response: Please see attached revised Exhibit C, 6.3.3(1)(f). The statement regarding benched overburden <br /> has been removed from Exhibit C, 6.3.3(1)(f). <br /> 10. Additionally under the heading 6.3.3(1)(f),the application states sloping or benching for excavations <br /> greater than 20 feet deep shall be designed by a registered professional engineer. In accordance with <br /> Rule 6.5(2),please provide engineering stability analyses for these slopes. Please also discuss the <br /> mining slope configurations and details for excavations less than 20 feet deep. <br /> Response: I have been unable to find a geo-tech engineer in this area(including Colorado Springs)willing <br /> and or available to provide a stability analyses report for excavations greater than 20 feet deep. <br /> See attached revised Exhibit C 6.3.3(1)(f)The statement regarding sloping or benching has <br /> been removed and a statement that excavations will not exceed 20 feet has been added. Also a <br /> statement was added regarding sloping up to 20 feet in depth will be followed in accordance <br /> with OSHA Section V, Chapter 2. <br /> Regarding Rule 6.5(2) <br /> We commit to items I &2 below while also factoring in items 3 &4 below. <br /> 1. I have proposed that excavations will not exceed 20 feet in depth. <br /> 2. I have added the statement(Exhibit C 6.3.3(1)(f)that sloping of excavated area will be in compliance <br /> with U.S. Dept. of Labor, OHSA Section V: Construction Operations, Chapter 2. Excavations: Hazard <br /> Recognition in Trenching and Shoring,with regard to sloping excavated areas. <br /> https://www.osha.gov/dts/osta/otm/otm—v/otm—v-2.html <br /> More specifically: <br /> IV. Determination of Soil Type <br /> V. Test Equipment and Methods for Evaluating Soil Type. (A pocket penetrometer will also be <br /> used to measure the compressive strength of the soil to assist in determining safe sloping.) <br /> VIII. Sloping and Benching. <br /> IX. Spoil <br /> 3. The existing surface slopes are not excessively steep. <br /> 4. The anticipated soil types are Stable Rock,Type A and B. <br /> Page 3 of 8 <br />
