Sue,
The stream crossing were designed to minimize the impacts to the streams. The temporary stream crossings are
designed at a width only wide enough to allow construction equipment to pass of the temporary crossings. We extended
this "narrow' limits to a point where the excavator can turn and reach materials and soils. If we were to reduce the
impacts areas to 20' or 30' through the entire zone 1 stream buffer then we would have to carry soils by off road dump
trucks and that would create more damage to the surrounding sensitive areas like the zone 2 buffers and the wetlands.
It is impossible to construct the temporary stream crossing with large diameter pipes through a reduced width area. To
us this reduction in width of impact at the stream crossings is utilized to a point that it is practical for this project.
Thank You,

Ok, that makes sense why some were left out. Thanks for that clarification.

As to your other clarification, I see what you are saying, and I guess technically you are correct. I've never seen that
done before. It's a bit more of a headache to parse it out like that but we can manage. It does bring up the question
though: why are they able to decrease the construction corridor at the TOB and not decrease it through the entire
buffer area, or at least all of Zone 1? The rules say that activities are allowable provided there are no practical
alternatives. Your plan sheets sort of show there is a practical option for narrowing the corridor for a short
distance. What makes the difference between narrowing for 10 feet on either side and not 30 feet on either side of
TOB?

Hi Sue —
The stream crossings left off were impacts that are except from mitigation. My interpretation of an exhibit with
allowable buffer impacts shown was that I didn't need to show exempt impacts. I will include these crossings with the
next updated version of this exhibit.
I wanted to clarify a crossing like the one shown below (many of the crossings are similar to this). Would this Zone 1
buffer be classified as allowable or exempt? Through the Zone 1 buffer there is both a 45 ft PE width and 20 ft PE width,
as the PE is narrowed at the TOB crossing the stream.

Hi Amanda,
Now that I've had a chance to look over the buffer impact drawings I'm more confused about the buffer impact table
you previously provided.
In the table comments column there are statements of Zone 1 exempt, Zone 1 allowable for one impact location. It
can't be both in one location, it either falls under exempt or under allowable. The drawings you provided indicate most
of them are allowable but a few seem to have both shown and I can't understand why. Also, there are some impact
rows/locations shown on the table that aren't shaded on the drawings. Was that just an error or is there some reason
that some of the buffer impacts weren't shaded on the drawings?
If it would be easier to go over this by phone let's schedule a time so we can have the documents in front of us.

Hello Amanda,
Happy New Year. Thank you for revisions to this project which meet the Jordan Buffer Rules Table of Uses and footnote
requirements.
I have one additional request for this project. Would you please clearly show the allowable buffer impacts on the plan
sheets. Something similar to how you show the permanent and temporary wetland impacts in color. If you could please
shade the permanent and temporary buffer impacts separately for all allowable areas (I do not need this for exempt
activities, but if its easier for you to show those too please use a different color scheme). Please let me know if you have
any questions/concerns.
Thanks

Hi Sue & David —
Please find attached the updated plans for the Birch Creek Sewer Improvements. I have also included the wetland and
waterbody table as we updated some notes on those.
As we previously had issues with both WeTransfer and Dropbox, the plans are coming in 3 separate emails. This email
contains:
1. Birch Creek Sewer Improvements — Phase I (excluding the detail sheets)
David, the permanently maintained corridor and construction corridor have been shaded on these plans as well.
Happy Holidays!
Thanks,

Thank you for your PCN and attached information, dated and received 9/24/2019, for the above referenced project. I
have reviewed the information and need clarification before proceeding with verifying the use of Nationwide Permit 12
(Blocked http://saw-reg.usace.army.mi l/NWP2017/2017NWP12.pdf) and 18 ((Blockedhttp://saw-

reg.usace.army.mil/NWP2017/2017NWP18.pdf) . Please submit the requested information below (via e-mail is fine)
within 30 days of receipt of this Notification, otherwise we may deny verification of the use of the Nationwide Permit or
consider your application withdrawn and close the file:
1) Per NWP 12 General Conditions 23 (a) and (b) as well as 4.1.1, directional drilling/boring methods should be
used to the maximum extent practicable. If these methods are not practicable, clearly explain why;
The stream crossings will be used as permanent maintenance crossings to maintain the sewer lines. The
installation of the permanent crossings will impact the streams even if directional drilling/boring methods are
used.
2) Per the email from NCDWR on 10/2/2019, if any crossings are proposed to be re -aligned to comply with state
rules, please notify the Corps immediately along with a timeframe for re -submitting the information for our
review;
The type of stream/wetland impacts have not changed, however, the sewer has been re -aligned to comply with
Zone 1 buffer rules. We are still working on updating the plans with these changes, as well as wetland comments
mentioned below, and we will send those as soon as they are finished.
3) The following items pertain to the plan sheets C1-19 (Phase 1) and C1-5 (Phase 11):
a. Various wetland shapes are noticeably different on the survey than on the email -confirmed PJD you
submitted on 8/1/2019. Such wetlands include W-06, W22 (not shown on the plan sheets), S13 (not
shown on the plan sheets), W26, and W27. Please carefully review the plan sheets, ensure that the
wetland boundaries are shown accurately to what was verified by the Corps in the field, and explain any
discrepancies. Once all discrepancies have been accounted for, please update the PCN and other
relevant tables with proposed wetland impacts and compensatory mitigation;
Wetlands were reviewed and edits were made to correct wetlands that were missing survey flags. Any
other discrepancies are due to GPS error, the PJD was created using field GPS surveyed data and the
plans show field surveyed data. W022 and 5013, which were inadvertently missing from the first set of
plans, are now shown.
b. Please distinguish through shading or other means the permanently maintained corridor vs. the
construction corridor (i.e. temporary impacts only) within wetland areas;
An exhibit will be included with the plans that distinguishes between the permanently maintained
corridor vs. the construction corridor within the wetland areas.
c. "Stream Crossing 7" is a linear wetland rather than a stream. Please update the plans and PCN
accordingly;
Label on plans will be revised to show a Linear Wetland Crossing. This linear wetland crossing was not
included in any of the PCN stream impact tables, its impacts are totaled in the wetland table as TG-W24.
The profiles do not always show grades that indicate a stream channel (e. e.g. Stream Crossings 1, 3, and
8). Also, not all stream channel crossings show rip rap stabilization. Please ensure that all stream
crossings where rip rap is proposed are shown on the profile drawings;
Plans will show permanent crossings in profile view. Since the initial PCN submittal on September 24,
2019, updated survey files have been received and incorporated into the plans, all stream channels
should appear on the profile.
4) On the PCN and associated tables, please ensure that the permanent fill proposed for manholes in wetlands
extends the correct amount of decimal places to record the impact. Currently the impacts show "0.000."
The PCN impact table and ILF request have been updated to include the appropriate number of decimal places
for the permanent fill proposed for the two manholes in the wetlands.
5) The following items pertain to your compensatory mitigation proposal:

The Corps concurs that Wetland W19 is a PEM wetland and there would be no permanent conversion
impact to this resource as proposed. However, a portion of Wetland W03 is forested. Further, Wetland
W15 is a PSS wetland, and these wetland types are treated the same as forested by the Corps. As such,
please update the PCN and your compensatory mitigation proposal to account for permanent
conversion impacts to Wetlands W03 (a portion) and W15 (all);
The permanent conversion impact of the forested version of Wetland W03 was included in the original
ILF request. However, the form has been updated based on alignment changes per NC DWR comments
and to treat Wetland 15 (PSS) as a permanent conversion.
b. Will the wetland area proposed to be crossed via jack and bore still be cleared and permanently
maintained? If so, include this as a permanent maintenance impact in a forested wetland; compensatory
mitigation requirements apply;
The areas where we are using Bore & jack methods will not be cleared and maintained.
c. Note that the permanent fill impacts due to manholes (although small) would require compensatory
mitigation at 2:1 due to permanent loss;
Concur, the ILF form shows the fill impact for the two manholes and we understand that compensatory
mitigation will be at 2:1.
d. Note that all wetlands proposed for permanent conversion are considered Riparian, non-riverine
regarding wetland mitigation type. There are wetlands considered to be non -riparian by the Corps on
this project;
ILF request form has been updated per this comment.
e. Please update your NCDMS acceptance letter according to the above;
The ILF Request form revision will be sent to DMS and we will forward their response when it is received.
6) Given the potentially suitable habitat for small whorled pogonia and Schweinitz's sunflower within the project
area, please provide additional information to enable an effects determination for these species. Have surveys
been completed for either species? Unless a No Effect determination is warranted, consultation is required with
the USFWS pursuant to Section 7 of the Endangered Species Act. Please note that the Corps cannot verify the
use of a NWP until Section 7 consultation is complete;
An online project review request was submitted to US Fish and Wildlife Services on October 28, 2019 and they
have 30 days to respond. We will forward the response when it is received.
7) Please note that responses to the questions above may prompt additional information requests to allow full
evaluation of the proposed project.
Please let me know if you have any questions.
