Hi Katherine,
Please find the attached revised plans for contract 2. Additionally, please see below (client response in red):
The 50-foot LOD is necessary because the outfall depth of the sewer is deep (24"). Thus, they need bigger equipment
with larger reaches and larger tracks, including a heavy track hoe excavator, room to operate with trench box or other
shoring materials, and the necessity to excavate and store native soils adjacent to the trenched areas, to reduce impact
to wetlands and keep native soil profile. Additionally, if groundwater is high, they need room for pumps and hoses to
pump out groundwater (dewatering equipment).
Diameter
Total (LF)
24
11,200
18
3,600
14,800
Please find responses to your requests below:
Could you provide revisions or more information for the following:
The impacts for W1 on the PCN do not match the impacts listed on the attached set of plans. - I've looked at this
and found the following:
a. The temporary and permanent impact totals for W1 on the cover page are incorrect. Agree and
updating Table
b. The temporary impact total on page 16 for W1 is also incorrect. Updated. For 1321.82 SF Temp impact
on sheet 13, the AC conversion is incorrect (SF call out correct). Attached version address
c. The detail on page 13 for W1 impacts shows that some of the impacts listed are for contract 3. It looks
like they added the contract 3 temporary and permanent impacts on page 13 into the total for contract
2, except instead of adding 0.146 acres of temporary impact from contract 3, they added 0.0146.
Updated. For 1321.82 SF Temp impact on sheet 13, the AC conversion is incorrect (SF call out
correct). Attached version address
d. So, according the correct total impacts for W1 in Contract 2 are as follows:
i. Temporary - 0.1261 acres
ii. Permanent - 0.0353 acres
2. Similarly, the totals for wetland temporary and permanent impacts on the PCN don't match the plan set. -I've
looked at this and found the following:
a. With this adjustment the correct total wetland impacts for Contract 2 are very close to the previously
listed totals on the PCN, as follows:
b. Temporary - 2.7668 acres

c. Permanent — 0.7119 acres
d. Total Wetland Impact — 3.4787 acres
e. Please let me know if this seems right to you. Not updating as numbers work once the AC conversion
item was addressed.
f. S9 has zero impacts — should it be removed? It looks like the stream origin point is at the edge of the
LOD. Do you know when or who established that point? Will white out callouts to S9.
3. Please update the total linear feet of 24" and 18" pipe that will be installed with Contract 2. The narrative lists
the total for the whole project, which is fine but my authorization needs to include the pipe installation
authorized for only Contract 2. Summary breakdown table provided in e-mail above.
4. Also, to verify consistency with the regional conditions, please let me know the width of the LOD. Updated
drawings to show 50' LOD. Provided explanation for exceeding 40' wide on the phone call (Equipment to
install 24", depth of sewer and safe trench practice, storage of excavated native soil, and trench dewatering
equipment.
5. Please revise the plans to reflect the accurate impacts, please add dimensions to the LOD area (width), and date
the plans to reflect the revision. See Attached

Hi Erin,
We need accurate Plans of Record to be attached with the permit verification. Please revise the plans to reflect the
accurate impacts, please add dimensions to the LOD area (width), and date the plans to reflect the revision.

- Similarly, the totals for wetland temporary and permanent impacts on the PCN don't match the plan set.
- S9 has zero impacts — should it be removed? It looks like the stream origin point is at the edge of the LOD. Do

Hello,
I've received your materials but I'm still going through the application, the permit process is moving forward. I was
looking through the materials to see if I could find the width of the limit of disturbance to be sure it meets NWP Regional
Condition 10 (b). I see the width of the maintained easement is 10'. Is the width of the LOD listed on the plans
anywhere?
For reference:
Regional Condition 10.
b. The work area authorized by this permit, including temporary and/or permanent fills, will be minimized to the
greatest extent practicable. Justification for work corridors exceeding forty (40) feet in width is required and will be
based on pipeline diameter and length, size of equipment required to construct the utility line, and other
construction information deemed necessary to support the request. The permittee is required to provide this
information to the Corps with the initial PCN package.
Thanks,

Good morning,
After my initial review of the permit request I have a few comments and requests for more information.
1. 1 see the expired permit for all the impacts that were separated into 4 contracts. Please show on a separate
figure any parts of the project that were completed and the impacts associated. Awaiting additional figures
from the design engineer. Will send ASAP.
2. The narrative indicates there was some or all mitigation paid previously. Please send the executed Mitigation
Transfer Form showing what was purchased. If there were partial mitigation purchases please indicate which
impacts these were for. See the signed MTF and DMS receipt of payment attached.
3. Stream impacts in the ePCN do not match the impacts stated in the letter request dated November 3,
2023. Also, stream impacts should also be shown in acres as well as LF please. Impact numbers on the Cover
Letter have been updated to reflect the ePCN and the Impact Maps. See attached.
4. It is not clear if further mitigation is needed. The letter mentions splitting credits as needed based on availability
and I do not have an executed MTF. If more mitigation is required please obtain an updated acceptance letter
from the appropriate Bank or DMS. See the signed MTF and DMS receipt of payment attached.
5. Please submit a zoomed in project figure that shows only the area of Contract 2 with the impacts. Awaiting
additional figure from the design engineer. Will send ASAP.
6. There are several places the alignment could be straightened or slightly shifted to avoid impacts. Please provide
information as to why the alignment can't be tweaked for further minimization. I understand that a minimum
grade is needed, but please take a look at these and let me know if potential adjustments can be made.
Awaiting additional info from the design engineer. Will send ASAP.
a. Sheet 12 — Wetland WB: appears that straightening the alignment or angling differently could avoid the
tips of the wetland
b. Sheet 9—Wetland W18
c. Sheet 10—Wetlands W26-29
Sheet 11- Wetland WC: Shifting the alignment at the western manhole could avoid the wetland, also
there are temporary impacts wider than 10' in a small area. Why is that needed?
Thank you,
