NEWMONT <br /> DBMS Comment(italics): <br /> 70. Section 2.2 Climate. The narrative states 4.1 inches of'precipitation is used for the 100-year. 24- <br /> hour event. NO.4.4 .4tlas 14 indicates 4.26 inches is the more appropriate value. Please provide a <br /> source for the 4.1 inches. <br /> Newmont Response: <br /> As approved in TR-101. the 100-year 24-hour precipitation value is referenced from NOAA Atlas 14 <br /> Volume 8 Version 2 to be 4.1 inches <br /> DBMS Comment(italics): <br /> 71. Section 2.3 - Underground Workings. This section states it is anticipated that the underground <br /> workings within the footprint of 4 LF2 Phase will he removed during the development of the Schist <br /> Islands Pit. Please commit to documenting and remediating all underground workings encountered <br /> at the final buildout of the Schist Island prior to hackfilling to ensure no voids are created in the <br /> huckfill material underneath Phase 3 VLF2. <br /> Newmont Response: <br /> Language in Section 2.3 of the Geotechnical Exhibit has been updated to reflect that CC&V will remediate <br /> and document known and identified underground workings. <br /> DRMS Comment(italics): <br /> -2. Section 3.2, p. 3, 3th pa�aph. Was the depth to groundwater in BH-03 measured after the <br /> completion ofdrilling? If'so, what was the measured level" <br /> Newmont Response: <br /> The groundwater was not measured at the end of drilling the borehole. The water was estimated based on <br /> samples recovered and interpretations in the field. There was no recovery on the sample at 35 ft depth. <br /> Boring logs and photos of the core recovered at BH-05 are included in Attachment 13. <br /> DBMS Comment(italics): <br /> 3. Section 4.1, p. 2nd paragraph. The Division is concerned about the comment that pit huckfill <br /> material is not within the scope of this design. If this comment refers to backfill in the developing <br /> Schist Island Pit, then the Division will require a backfill program similar to that perfortned for the <br /> mill platform constructed on the southeast side o1.1"LF2. Ifthis refers to 'Jill"placed previously (15 <br /> to 20 years ago) with the development of the SGOS_4 in the vicinitvofinvestigative boreholes BH01 <br /> - BH-05 (reference December 5, 2019 VLF2 Phase 3 Issued.for Permitting Drtat,ing .403), more <br /> discussion is required to assure the Division proper.subgrade treatment will be performed prior to <br /> installing liner in this area. <br />
