Subject: Modification Request for Section 404 Individual Permit, Section 401 Water Quality
Certification and Neuse Riparian Buffer Authorization for Interstate 40 Widening and
Improvements from I-440/US 64 (Exit 301) to just north of SR 1525 (Cornwallis Road),
including improvements to NC 42 and SR 1010 (Cleveland Road) in Wake and Johnston
Counties, Federal Aid Project No. IMNHF-040-4(139)301; TIP Numbers 1-5111 and 1-4739,
Division 5. Debit$570 from WBS Element 42346.3.1.
Dear Mr.Williams:
As you are aware, the North Carolina Department of Transportation (NCDOT) applied for permits for
the subject project on May 7,2019,and modifications on December 20,2019,May 28,2020,and August
31, 2020. The Corps of Engineers issued the Section 404 permit for the project on September 6, 2019,
and modifications on February 11, June 11, and October 1, 2020, respectively. The North Carolina
Division of Water Resources issued the 401 Water Quality Certification for the project on July 10, 2019
(NCDWR Project No. 20190593) and modifications on January 22, June 3, and September 16, 2020,
respectively. This correspondence is to request modifications to Sites 1,4,44,47,and 48.
Site 1: There will be a reduction in stream impacts, as the contractor will not replace 2 @ 42"pipes,per
NCDOT preference. Additionally,the noise wall will now be shortened along with the berm ditch.
• 13 linear feet decrease in permanent stream impacts
• 14 linear feet decrease in temporary stream impacts
• 1,334 square feet decrease in Allowable buffer zone 1 impacts
• 856 square feet decrease in Allowable buffer zone 2 impacts
Attached are the following revised permit drawings depicting the affected area, all of which have a
revision date of November 19,2021:
• Permit Drawing 3: Ditch detail sheet
• Permit Drawing 9:plan sheet 4 without contours
• Permit Drawing 10: plan sheet 4 with contours
• Buffer Drawing 5: buffer plan sheet 4

Site 4: Noise wall installation required a stormwater drainage system shift beyond the cut/fill line and
outside of the noise wall(Plan Sheet 7),which resulted in moving the noise wall further to the east(Plan
Sheet 8). Therefore, additional buffer impacts are proposed.
• 1,187 square feet increase in Allowable buffer zone 1 impacts
• 973 square feet increase in Allowable buffer zone 2 impacts
• 614 square feet increase in Mitigable buffer zone 2 impacts
Attached are the following revised permit drawings depicting the affected area, which have a revision
date of either November 19,2021 or January 6,2022:
• Buffer Drawing 7: plan sheet 7
• Buffer Drawing 8: plan sheet 8
• Buffer Drawing 45: buffer summary table
Site 44: The following three modifications area proposed.
1) Wetland WEP(1)impacts were not accounted for originally while buffer impacts in the same area
were permitted. Since this entire area was needed for construction access and for installation of
erosion control measures, mechanized clearing in wetlands is now proposed for the portion of
this wetland within the ROW.
2) Outlet of SEQ: Design adjustments eliminated the need for a 54"WSP trenchless installation at
-L- 115+00 to STA 118+00 by keeping stormwater along west bound side of the highway. The
resulting pipe systems were slightly shortened during the field adjustment so that they would
better align with the stream channel and prevent instability to the stream bank. Additionally due
to construction accessibility and existing channel instability, rip rap was extended to the ROW
line.
3) In the upstream of SEQ (-L- RT east bound side), there was a temporary channel change
previously permitted. But based on site conditions, the contractor and Division agreed that the
site would be more stable if the stream was left in the temporary channel as opposed to shifting
back to the original, thus the temporary stream impacts are now permanent. No additional
increases to surface waters,wetlands,nor buffers are proposed in this area.
• 0.01 acre increase in mechanized clearing in wetland
• 11 linear feet increase of permanent bank stabilization
• 11 linear feet decrease of temporary stream impacts
Attached are the following revised permit drawings depicting the affected area, all of which have a
revision date of November 19,2021:
• Permit Drawing 7: Ditch detail sheet
• Permit Drawing 91: plan sheet 42 without contours
• Permit Drawing 92: plan sheet 42 with contours
Sites 47 and 48: Based on field conditions, the contractor had to adjust the pipe placement which
necessitated a larger PDE to allow for installation of a berm (requested by NCDOT Central Hydraulics
Unit). This made stream SLW at site 48 a total take, increased buffer impacts at Site 47, and removed
temporary stream impacts from site 47 due to the new limits of riprap (the temporary stream impacts
became permanent - location of bank stabilization of permanent impact now starts where stream is no
longer realigned).
Site 47:
• 35 linear feet increase of permanent stream impacts
• 24 linear feet decrease of permanent bank stabilization
• 11 linear feet decrease of temporary stream impacts
• 270 square feet increase of Allowable buffer zone 1 impacts
• 981 square feet increase of Allowable buffer zone 2 impacts

Site 48:
• 69 linear feet increase of permanent stream impacts
• 51 linear feet decrease of temporary stream impacts
Attached are the following revised permit drawings depicting the affected area, all of which have a
revision date of either November 19 or December 14, 2021:
• Permit Drawing 7: ditch detail sheet
• Permit Drawing 96: plan sheet 45 without contours
• Permit Drawing 97: plan sheet 45 with contours
• Permit Drawing 124: summary table
• Permit Drawing 125: summary table
• Buffer Drawing 51: buffer summary table
• Buffer Drawing 52: wetlands in buffer impact summary table
Compensatory Mitigation
These changes resulted in a total increase of 10 feet of stream impacts, including changes at Sites 1, 44,
47 and 48. For riparian buffers, there are 614sq. feet of additional impacts in buffer Zone at Site 4. Site
44 also has an additional 0.01 acre of mech clearing in wetlands.
NCDOT has requested the appropriate additional mitigation from the N.C. Division of Mitigation
Services, and a copy of their acceptance letter is attached.
REGULATORY APPROVALS
Section 404: NCDOT requests modification to the USACE Individual 404 Permit for the project as
required for the above-described activities.
Section 401: We are also requesting modification of the Section 401 Individual Water Quality
Certification and Neuse Riparian Buffer Authorization from NCDWR. We are providing this request to
NCDWR, for their approval. Authorization to debit the$570.00 Permit Application Fee from TIP No. I-
5111/I-4739/WBS 42346.3.1 is hereby given.
A copy of the permit modification request and its distribution list will be posted at
https://xfer.services.ncdot.gov/pdea/PermApps/.

*Some of the additional stream impacts may be proposed to be mitigated at a 1:1 mitigation ratio.See permit application for details.
DMS will provide the amount of mitigation as determined by the regulatory agencies.
All buffer mitigation requests and approvals are administrated through the Riparian Restoration Buffer
Fund. The NCDOT will be responsible to ensure that appropriate compensation for the buffer mitigation will be
provided in the agreed upon method of fund transfer. Upon receipt of the NCDWR's Buffer Authorization
Certification,DMS will transfer funds from the NCDOT 2984 Fund into the Riparian Restoration Buffer Fund.
Upon completion of transfer payment,NCDOT will have completed its riparian buffer mitigation responsibility
for the additional buffer mitigation required for TIP Number 1-5111 /1-4739. Subsequently,DMS will conduct
a review of current NCDOT ILF Program mitigation projects in the river basin to determine if available buffer
mitigation credits exist. If there are buffer mitigation credits available,then the Riparian Restoration Buffer
Fund will purchase the appropriate amount of buffer mitigation credits from NCDOT ILF Program.
This mitigation acceptance letter replaces the mitigation acceptance letter issued on April 26,2019
and January 15,May 27,and September 11,2020. DMS commits to implementing additional sufficient
stream,wetland and buffer mitigation credits to offset the impacts associated with this project as determined by
the regulatory agencies using the delivery timeline listed in Section F.3.c.iii of the In-Lieu Fee Instrument dated
July 28,2010. If the above referenced impact amounts are revised, then this mitigation acceptance letter will no
longer be valid and a new mitigation acceptance letter will be required from DMS.
If you have any questions or need additional information,please contact Ms. Beth Harmon at 919-707-
8420.
