Newmont-Cripple Creek&Victor Gold Mine y■ <br /> Technical Specification No.02200.DOCX ■ <br /> Squaw Gulch VLF <br /> Project No.475.0106.006 <br /> June 15,2016 <br /> 10. The CQA Monitor will measure the ambient air temperature on an hourly basis. If <br /> the ambient air temperature is less than thirty-two degrees Fahrenheit for more <br /> than one hour over the preceding twenty-four (24) hours, the CQA Monitor will <br /> measure the temperature of the fill to determine if the fill is frozen. "Frozen" is <br /> defined as a mean temperature of thirty-two degrees Fahrenheit (321) or less.The <br /> CQA Monitor will measure the temperature at a depth of three (3) inches and six <br /> (6) inches, recording the lower of the two. Six (6) measurements will be taken per <br /> acre, and if the average is below thirty-two degrees Fahrenheit (32°F), the fill will <br /> be considered frozen. If the fill is determined to be frozen the CONTRACTOR may <br /> either remove and replace the frozen fill or wait until subsequent temperature <br /> monitoring indicates the fill is unfrozen at no cost to CC&V. <br /> 11. Overburden slopes shall be compacted using a method specification and graded to <br /> meet the grades and dimensions shown on the DRAWINGS. The Bedding Fill <br /> subgrade surface will be prepared as identified in Section 2200 of the <br /> SPECIFICATIONS. <br /> B. Structural Fill <br /> 1. Areas to receive Structural Fill will include, but are not limited to, slope reductions, <br /> and miscellaneous site grading. <br /> 2. CONTRACTOR shall condition Structural Fill to a moisture content that allows <br /> compaction to the required density and that results in a firm, unyielding surface <br /> capable of allowing the movement of vehicles and equipment over the surface <br /> without causing rutting or other deleterious effects. <br /> 3. CONTRACTOR shall place Structural Fill materials with less than 30 percent rock <br /> materials above 3/4-inch size in maximum 12-inch loose lifts, and compact to 95 <br /> percent of maximum dry density(ASTM D698). <br /> 4. CONTRACTOR shall condition, place and compact Structural Fill containing more <br /> than 30 percent rock materials above 3/4-inch size(rock fill) by a method <br /> compaction technique. The compaction equipment shall consist of a minimum 10- <br /> ton (static drum weight) vibratory smooth-drum compactor. The number of passes <br /> and loose lift thickness shall be subject to CERTIFYING ENGINEER's approval, at no <br /> additional cost to CC&V. The method SPECIFICATIONS may be changed at any time, <br /> at the discretion of CERTIFYING ENGINEER, based upon changes in material <br /> characteristics, field conditions, and/or compaction equipment. <br /> 5. Maximum rock size for rock fill shall be two-thirds of the compacted lift thickness, <br /> unless otherwise approved by MANAGER, DESIGN ENGINEER, and CERTIFYING <br /> ENGINEER. CONTRACTOR shall remove oversize materials from fills at no additional <br /> cost to CC&V. <br /> Page 11 <br />
