Hi all,
I know several members of the IRT are in the field this week and may not have time to review the Liberty Rock
revised technical approach. I think it's best to stick to the Folly Swamp discussion for Friday since it's a pending
bank site, I'd rather not mix a DMS site discussion with one of our project manager's meetings. I think it would
be beneficial if everyone could review the Liberty Rock information provided by Angela and provide written
comments to me by December 30, 2020. That way it goes through the 15-day review period. I'll forward all
comments received in a memo to Wildlands so they have a path to move forward. Please indicate whether
you are comfortable with the revised approach. Given the holidays, please let me know if you need additional
review time.
Thanks, and I hope everyone is well,
Kim

Since we are having a discussion with Wildlands on Friday (9am) for Folly Swamp would it be appropriate to
add this site on for additional discussion with the IRT? Just wanted to minimize time before we consider and
provide Wildlands with a response. J

Attached is a technical memorandum showing the change in restoration approach for Liberty Rock Mitigation
Site based on our virtual meeting and subsequent design site visits. Please let me know If you have any further
questions for us and if we are approved to move forward with this approach.
Thank you,

MEMORANDUM FOR RECORD
January 5, 2021
SUBJECT: Liberty Rock Mitigation Project - NCIRT Comments during 15-Day Updated Technical
Memo Review
PURPOSE: The comments listed below were received during 15-day comment period in accordance
with Section 332.8(o)(9) of the 2008 Mitigation Rule in response to the NCDMS Technical Proposal
Update Review.
NCDMS Project Name: Liberty Rock Mitigation Site, Randolph County, NC
USACE AID#: SAW-2020-00047
15-Day Comment Deadline: January 4, 2021
USACE Comments, Kim Browning:
We agree with the revised proposal. The IRT requests copies of the mussel survey memos each time
they are conducted, and will need to be reviewed prior to construction. We also request that we are
notified prior to construction so we can schedule an IRT site visit.
WRC Comments, Travis Wilson:
We have reviewed memo and had some internal discussion and are in agreement with the information
outlined. Obviously moving forward there will need to be additional coordination associated with
specific issues such as identifying the relocation reaches etc. But we are in agreement with the new
approach and it accurately captures our IRT discussions and WRC comments.
However what is still unclear is if Wildlands has the necessary mussel survey data to use during design.
Wildlands needs a thorough survey of the reach that will be retained in place, plus some minimal
additional upstream area in case adjustments are necessary for the tie in point. That survey information
is important to identify sensitive areas that are currently providing habitat for mussels populations and
can be accounted for during design and construction . We are not sure what level of mussel survey
was conducted by their consultant, so it's possible they may have the necessary information we just
aren't aware. Once that information is available WRC would like to see the results of the survey. Again,
It's not necessary to have survey information for the reach that will be abandoned as those mussels, if
present, will be relocated. If you have any additional questions please give me a call.

EPA Comments, Todd Bowers:
I have reviewed the technical memo concerning enhancement work, mussel habitat protection and the
monitoring schedule for the mussels as well as revised credits for the work at Liberty Rock. I will defer
to the wildlife agencies to provide critical input as far as the mussels are concerned with this site as it
their purview and area of expertise. With that I have no further concerns or comments as it pertains to
the Liberty Rock mitigation site technical Memo Option 3 dated 14 December 2020. Wildlands appears
to have offered a reasonable and sound approach to providing functional uplift as well as gaining extra
credit for wider riparian buffers and monitoring of important mussel species. Thank you for the
opportunity to provide feedback on the aforementioned technical memo.
DWR Comments, Erin Davis:
DWR requests that the IRT get copies of the mussel survey memos (not just WRC), ideally as an
appendix to the annual monitoring reports if the timing lines up.
USFWS Comments, Kathy Matthews:
Emily and are comfortable with the proposal also, as long as the surveys are completed as required,
and survey data and reports are shared with the USFWS. If a federally -listed species is documented,
we would like to know that ASAP.
