Michael,

Thank you for your PCN, dated 4/21/2022, for the above referenced project. I especially appreciate the thorough description of on-site habitat, which will greatly ease my coordination
with USFWS. That said, there are a few areas of clarification needed before I can proceed with verifying the use of Nationwide Permit (NWP) 29 (https://saw-reg.usace.army.mil/NWP2021/NWP29.pdf
<https://urldefense.com/v3/__https://saw-reg.usace.army.mil/NWP2021/NWP29.pdf__;!!HYmSToo!fOH4RXalWi7_0pGznexc6ShciojwbN__-DQFVPSvwKs1QfROkb-ZGlUlbE-NPHRIU2Q-HS5eLmBmauYjt7hifBn5$>
). 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Permit or consider your application withdrawn and close the file: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. For the road crossing impact the PCN references rip rap, and plansheet “Perennial Wetland Impact Map” references “Road/Culvert Impact.” However, no culvert or rip rap is shown through
the wetland impact necessary to continue flow and circulation of waters of the US (i.e. Wetland WA) downslope. As currently designed the crossing may not comply with NWP 29 General
Condition 8, and may also result in additional indirect impacts (per NWP 29 District Engineer’s Decision part 2) to Wetland WA through alteration of hydrology downslope. Please revise
the plans accordingly;
2. The “Perennial Stream/ Wetland Impact Location Map, Rock Creek Station Apartments” shows a plunge pool discharge from a wet detention pond and what appears to be a rip rap pad extending
to the edge of Wetland WD. Please provide a zoomed-in detail plan showing this area in greater detail in order to facilitate our full evaluation of this project.

Sue, please advise as to the 401 requirements for this project so that, if an Individual 401 WQC is required we can implement our responsibilities under the EPA’s 2020 Clean Water Act
section 401 rule.

Please let me know if you have any questions.

Sincerely,

Dave Bailey

INSTALLATION NOTES:
1. REFER TO "NORTH CAROLINA DIVISION OF FOREST
RESOURCES" LITERATURE, INSTALLATION
MAINTENANCE GUIDELINES, & "NORTH CAROLINA
FORESTRY BMP MANUAL-2006".
2. USE A BULLDOZER, KNUCKLEBOOM LOADER, OR
SKIDDER TO INSTALL & REMOVE DRAGLINE MATS.
3. KEEP HEAVY EQUIPMENT OUT OF STREAM.
4. INSTALL WATER DIVERSION DEVICES (WATER
BARS, TURNOUTS, BROAD —BASED DIPS, ETC.) ON
BOTH SIDES OF THE MATS.
5. STABILIZE EXPOSED MINERAL SOIL WITH TREE
TOPS OR BRUSH DURING MAT INSTALLATION, AND
SEEDING/MULCH AFTER MAT REMOVAL.
6. INSTALL MATS TO CREATE A MINIMUM TEN FOOT
BRIDGE WIDTH.
MAINTENANCE NOTES:
1. KEEP MATS' SURFACE FREE OF MINERAL SOIL
AND DEBRIS THAT COULD ENTER STREAM.
2. PERIODICALLY CHECK MAT HARDWARE; RETIGHTEN
NUTS & CABLE CLAMPS AS NECESSARY TO
MAINTAIN BRIDGE STRENGTH AND INTEGRITY.
3. IMMEDIATELY REMOVE ANY DEBRIS WHICH ENTERS
THE STREAM AT THE CROSSING LOCATION.
REMOVAL NOTES:
1. CLEAN OFF BRIDGE SURFACE.
2. REMOVE MATS BY USING MAT CABLE LOOP OR
SKIDDER GRAPPLE.
3. PERMANENTLY STABILIZE DISTURBED PORTIONS
OF STREAM BANK AND APPROACH ROADS WITH
PERENNIAL GRASSES/MULCH (OR WETLAND MIX
WHEN APPLICABLE).
4. LEAVE APPROPRIATE WATER DIVERSION
STRUCTURES IN PLACE ON BOTH SIDES OF
STREAM.
