Cripple Creek&Victor Gold Mining Company <br /> Squaw Gulch VLF Phase 2A Part 2 ■ <br /> Record of Construction Report <br /> 475.0106 032 <br /> September 30,2019 <br /> No laboratory compaction testing was performed on the SF placed within the Squaw <br /> Gulch VLF Phase 2 area, as all SF material contained more than 30 percent retained on <br /> the %-inch sieve. Density was achieved by placing the material in accordance with the <br /> method compaction specifications presented in Appendix D. <br /> 3.2.2. Leak Detection Fill <br /> The Squaw Gulch VLF Phase 2A Part 2 area was constructed by placing 14 cy of LDF. The <br /> particle size distribution and Atterberg limits testing frequencies were one sample for <br /> every 10,000 cy. One LDF sample was required to be tested for particle size and Atterberg <br /> limits. One LDF sample was tested with passing results. LDF laboratory testing is <br /> summarized in Table 6 and individual test results are presented in Appendix H.2. <br /> 3.2.3. Soil Liner Fill <br /> The Squaw Gulch VLF Phase 2A Part 2 area was constructed by placing 64,430 cy of SLF. <br /> The particle size distribution, Atterberg limits, laboratory compaction, and permeability <br /> testing frequencies were one sample for every 4,000 cy. A minimum of 17 SLF record <br /> samples were required to be tested for particle size distribution, Atterberg limits, <br /> laboratory compaction, and permeability testing. A total of 20 SLF record samples were <br /> tested with passing results. SLF laboratory testing is summarized in Table 7 and individual <br /> test results are presented in Appendix H.3. <br /> The nuclear density/moisture testing frequency for SLF is one test for every 500 cy. A <br /> minimum of 129 SLF nuclear density/moisture tests were required. A total of 171 SLF <br /> nuclear density/moisture tests were performed with passing results. The depth check <br /> frequency for SLF is two checks for every acre. A minimum of 80 SLF depth checks were <br /> required. A total of 110 SLF depth checks were performed with passing results. SLF <br /> nuclear density/moisture testing and SLF depth checks are presented in Tables 9 and 10, <br /> respectively. <br /> 3.2.4. Drain Cover Fill <br /> The Squaw Gulch VLF Phase 2A Part 2 area was constructed by placing 128,860 cy of DCF. <br /> The particle size distribution and Atterberg limits testing frequencies were one sample for <br /> every 20,000 cy. A minimum of six DCF samples were required to be tested for particle <br /> size and Atterberg limits. A total of seven DCF samples were tested with passing results. <br /> DCF laboratory testing is summarized in Table 8 and individual test results are presented <br /> in Appendix H.4. <br /> P:\Projects\Cert Report-Phase 2A Part 2\475.0106.032 CCV PHASE 2A Part 2 ROC REPORT docx <br /> Page 9 <br />
