Clement/Tyson,
Attached are the comments received in response to the Public Notice. As noted in DWR's letter, I will work on finalizing
the Approved JD so they can moved forward with finalizing their review. Please submit the JD Form that I emailed the
other day to assist me with finalizing that piece.
In regards to the comments received, please address WRC's comments relating to additional information regarding
sediment and erosion control measures for the tailings. With regards to their request and USFWS's request that
mitigation be increased to 2:1 for both stream and wetlands, I believe your NCSAM documents the lower mitigation
ratios with the exception of Stream S4. It has a medium rating and was likely degraded by past mining activities. Please
revise the ratio for this one to 1.5:1.
With regards to the specifics of the plans, my only question/comment is related to the 610 linear feet and 0.054 acre of
wetland that will be avoided next to Basin OL-2B. Looking at the stormwater/basin plans, it appears that water being
collected in Basin OL-2A will be collected and piped directly into OL-2B which won't discharge until the end of the
stream reach. My concern is that the hydrology of this channel/wetland will be negatively affected and essentially dry up
and no longer be jurisdictional and therefore should be considered an impact. Please review the plans for this section
and provide a response.
All responses/request for additional information should be received within 30 days to continue the review of this
application. Please contact me with any questions, thanks.
