be compliance sites. Please provide a list of all compliance surface water and
groundwater monitoring sites,including the GPS coordinates for each location.
Additionally, because you are providing data from other(non-compliance)
monitoring sites, please show the locations of these sites either on Figure 2-1
(differentiating them from compliance sites) or on a separate figure.
RESPONSE: A list of compliance monitoring points for both surface and groundwater is
provided in Tables 1 and 2 in Attachment 2 along with coordinates for each. A revised
Figure 2-1 also is provided, which shows the compliance monitoring points and other
monitoring locations. Note Figure 2-1 provides a site-wide view of the entire monitoring
area. Figures 2-1 a and 2-1 b (also included in Attachment 2) show the monitoring
locations within the permit area detail and the Carlton Tunnel, respectively.
3.1.3.1 Monitoring Program
• Page 8: The text lists 3 groundwater monitoring wells, including WCMW-02, WCMW-03,
and WCMW-06. However, only WCMW-03 and WCMW-06 are shown on Figure 2-1.
Please revise Figure 2-1 to show locations of all monitoring sites discussed in this
section.
RESPONSE: As noted above, a revised Figures 2-1, 2-1 a and 2-1 b are included in
Attachment 2.
3.1.4 Current Conditions
• Page 10: The text states that the Vindicator Valley drainage is shown on Figure 1-1.
However,this drainage is not labeled on Figure 1-1. Please revise Figure 1-1 to label
this drainage.
RESPONSE. A revised Figure 1-1 is provided in Attachment 2, which shows the
different drainages mentioned in the report.
• Page 11: The text indicates that multiple EMPs may exist for Vindicator Valley.
However, Figure 1-1 appears to show only EMP-012. Is EMP-012 the only EMP
associated with Vindicator Valley?
RESPONSE. The text of the report refers generally to the use of EMPs at the site
including EMP-012, which is located in Vindicator Valley. Note that EMPs are the
final terminus control for stormwater management at the site. Several BMPs are
installed upstream of the EMPs. Detailed stormwater designs have been conducted
for each drainage at the site and appropriate BMPs and EMPs installed. The
stormwater controls for Vindicator Valley Creek drainage were designed and
constructed pursuant to past permit amendments and captured in the site-wide
Stormwater Management Plan, a copy of which was included as Appendix 12 to the
Amendment 10/MLE2 permit. EMP ponds are constructed for twice the volume of
the 10 year/24 hour storm event. There are no changes proposed for Vindicator
Valley under Amendment IL As such, no additional stormwater designs were
considered.

4.1.1 Current Conditions
• Page 14: The text states that the Poverty Gulch drainage is shown on Figure 1-1.
However,this drainage is not labeled on Figure 1-1. Please revise Figure 1-1 to label
this drainage.
RESPONSE: A revised Figure 1-I is provided in Attachment 2 with the different
drainages mentioned in the report labeled.
