Road 821 and the Grassy Valley monitoring well access road. Revised Exhibit S is included in
Attachment 8.
• 27. Please identify all permanent man-made structures within 200 feet of the affected lands
associated with these two areas of AM14 proposed affected land expansion. Please verify
if any structures within 200 feet of these areas are already accounted for in the existing
AM11/AM13 Exhibit S or demonstrate compliance with Rule 6.4.19 for any new structures.
Please note,for new structures,the Operator must first attempt and demonstrate
compliance with Rule 6.4.19(a) prior to evaluating the structure as a part of Rule 6.4.19(b).
Exhibit S, Section 1, Paragraph 3 states that two structures were identified within 200 feet of the area
that is affected by the changes under this Amendment 14, i.e., the employee parking area along County
Road 821 and the Grassy Valley monitoring well access road. These structures include a historical
headframe and are located on Tenderfoot Hill, northwest of the main mine site (see Drawing C-1 a,
Plate 1 of 4). A signed and notarized Structure Agreement was included with this exhibit in the
Amendment 14 submittal and is provided again in Attachment 8. No permanent manmade structures
were identified within 200 feet of the Grassy Valley monitoring well access road, and no other new
structures within 200 feet of the affected lands boundary have been identified. This paragraph was
revised for clarity to state that two structures were identified within 200 feet of the employee parking
area, and no structures were identified within 200 feet of the Grassy Valley monitoring well access road.
Exhibit U—Designated Mining Operation Environmental Protection Plan (Rule 6.4.21):
28. Within Section 2, it states that information related to the High-Grade Mill (HGM)facilities,
including chemical use and storage, is included in this Exhibit to describe the
environmental protection protocols used until and through decommissioning. In
conjunction with previous items in this review, it is understood that HGM is not currently
in use. Please clarify if the HGM is intended to be used again until the commencement of
construction of VLF2 Phase 4 expansion. If the mill is intended to be used, a recertification
• of the Mill including its liner system as an EPF will be required.
The HG Mill remains inactive. Prior to construction of the planned VLF Expansion, CC&V intends to
maintain operational flexibility and may utilize the existing HGM facilities to process HG ore. Prior to
resuming HGM operation, CC&V will work with DRMS to ensure safe, compliant and effective startup
of the facility.
29. Please identify any changes to Table U-1: Designated Chemicals and Table U-2:
Environmental Protection Facilities from the approved AM13 (including adequacy review
revisions)tables and the AM14 submittal.
No substantive changes were made to Table U-1 or Table U-2 from the approved AM13. Additional
acronyms were defined in Table U-1 for clarity. No changes were made to Table U-2.
30. Within Section 6 it states that the additions of VLF 1 Phase 6 and VLF 2 Phase 4 are
considered expansions to the existing approved VLF1 and VLF2 EPF, respectively.While
that may be true,a Facilities Evaluation of the expansions must be provided. Please
provide a revised Section 6 of Exhibit U addressing items a through f of Rule 6.4.21(7)for
both the VLF1 Phase 6 and VLF2 Phase 4 Expansions. The revised section should also
include more details regarding construction including area preparation, installation etc.
VLF 1 Phase 6 and VLF2 Phase 4 are expansions to already approved EPFs. The site-specific
conditions, designated chemicals, geological and geochemical settings, monitoring systems and
procedures, and response procedures are consistent with the already approved EPFs. Table U-2 in
Exhibit U, the Environmental Protection Plan, provides detailed information regarding each EPF,
including designated chemical usage and monitoring frequencies. Spill response details are provided
• in the Emergency Response Plan, provided as Appendix 12 to the original Amendment 14 permit
application. Additionally, locations and configurations of monitoring systems for VLF1 Phase 6 and
