NEWMONT <br /> GOLDCORR <br /> Adequacy Review No. 2, dated August 16, 2019: <br /> Report. <br /> 1. Section 2.11 — Drain Cover Fill: Please address the following discrepancy and provide <br /> clarification: <br /> a. 60,632 CY of DCF was placed within the Squaw Gulch VLF Phase 2A Part 1 <br /> area while Section 3.2.7 — Drain Cover Fill and Table 2 — Earthworks Testing <br /> Summary and Frequency both state 49,339 CY of DCF was placed. <br /> The correct volume of DCF placed within Squaw Gulch VLF Phase 2A Part 1 <br /> area is 60,632 CY. Attachment 8 includes the Earthworks Testing Summary <br /> and Frequency with the revised DCF quantity. <br /> Tables & Appendices: <br /> 2. Table 4 — Fill Temperature Monitoring Summary: Average fill temperature was recorded <br /> at 320F on 4123119 at 7:00, 511119 at 7.00, and 512119 at 7.00 and 8:00. Within 3.6 of the <br /> Technical Specifications, "Frozen" is defined as a mean temperature of thirty-two <br /> degrees Fahrenheit (32 OF) or less. Please address why SF and SLF placement <br /> occurred when fill material was frozen. <br /> Fill temperatures on the specified dates showing 32°F were reported as whole <br /> numbers. Attachment 9 includes the revised Fill Temperature Monitoring Summary <br /> with unrounded fill temperatures. <br /> 3. Table 12— Nuclear Gauge Moisture-Density Testing Summary— Soil Liner Fill: SLF-33- <br /> N and SLF-34-N both tested on 6112119 passed while SLF-33-N-RT and SLF-34-N-RT <br /> both tested on 6120119 failed. Please provide clarification on why the retest samples <br /> were taken following testing which passed and why the retest samples failed. <br /> The nuclear density test results for SLF-33-N, SLF-34-N and their corresponding <br /> retests were reported in error. Attachment 10 includes the revised Nuclear Gauge <br /> Moisture-Density Testing Summary. <br /> 4. Appendix D.3 — Underground Workings Remediation As-built Figures: Figure No. UG42 <br /> uses the 8 Underground Plug Installation Detail as depicted on Figure No. UGI. UG 42 <br /> shows two polygons defined as Concrete while UG1 involves a Concrete Plug and <br /> Cemented Rockfill. Please provide an additional detail regarding UG 42 or correct the <br /> polygons to indicate the Concrete Plug and Cemented Rockfill. <br /> Figure No. UG42 (Attachment 11) has been revised to reflect the remediation <br /> performed for the corresponding underground working. <br />
