SUBJECT: Additional Information for the Section 404 Individual Permit Application
and Request for Modification to the Section 401 Water Quality Certification
for the proposed NC 24/27 Troy Bypass from west of SR 1138 (Dairy Road) to
just east of Little River, Montgomery County, Division 8. WBS Element No.
34352.1.1, TIP No. R -0623.
REFERENCE: R -0623 Individual Permit Application, dated March 10, 2014
NCDWR Project No. 2014 -0285, Certification No. 3992, dated May 23, 2014.
Dear Madam:
The purpose of this letter is to provide additional information for the Section 404 Individual
Permit application and request a modification to the North Carolina Division of Water Resources
Certification for the above referenced project. The additional information and modification is to
account for additional permanent stream impacts including bank stabilization, decrease in
temporary stream impacts, and additional permanent wetland excavation and hand clearing to the
project since the submittal of the above permit application. Utility impacts also were changed,
resulting in slightly less temporary impacts (see attached revised utility drawings). Also, please
find attached the revised NCEEP acceptance letter. Please replace the current permit drawings
with the new revised drawings (Revised Permit Drawing Sheets 12, 40, 41, 42, 43, 90, and 91 of
91) and revised utility drawings (Revised Utility Drawing Sheets 1 -5 of 5) attached' with this
letter.
Changes in stream impacts for Permit Sites 11 and 11A are associated with the recent design
change of the proposed pipe to box culvert. Permanent stream impacts (fill) will decrease from
322 linear feet to 319 linear feet for Permit Site 11 while bank stabilization will increase from 15
linear feet to 47 linear feet. Temporary stream impacts at Permit Site 11 will decrease from 83
linear feet to 56 linear feet. Permanent stream impacts (fill) will increase from 91 linear feet to
105 linear feet at Permit Site 11A while bank stabilization will increase from 0 linear feet.to 6
linear feet. Temporary stream impacts at Permit Site 11A will decrease from 41 linear feet to 21
linear feet. These revised impacts for Permit Sites 1 1 and 11 A are shown in the attached Revised
Permit Drawing Sheets 40 -43 of 91, and 90 of 91, and in Table 1 below in bold and italicized
font.

Notes- Totals are rounded based upon sum of actual impacts *The wetland at Permit Site 9 is an isolated
and therefore, a non -404 regulated wetland Mitigation for this site will only be required by NCDWR
at 2:1 ratio.
Revised compensatory mitigation requirements for R -0623 are summarized below in Table 3.
This project will permanently impact 4,916 feet of warm water streams. Of these 4,916 feet,
there are 347 feet of bank stabilization that do not require mitigation by the USACE, resulting in
4,569 feet of stream impacts requiring USACE mitigation.
The USACE is requiring 2:1 mitigation for 3,128 feet and requiring 1:1 mitigation for 1,441 feet
of stream impacts. NCDWR is requiring 1:1 mitigation for 3,176 feet. Therefore, the total
USACE mitigation requirement exceeds the NCDWR requirement. The mitigation requirements
of 4,569 feet of permanent warm water strearn impacts will be provided by the NCEEP for
R -0623 (Table 3)
This project will also permanently impact 1.23 acres of wetlands. The wetland at Permit Site 9
(0.03 acres) does not require mitigation by USACE due to its isolated status. However, this
wetland will require mitigation by -NCDWR at 2:1 ratio. The overall USACE mitigation
requirement is 1.20 acres at 2:1 ratio while the overall NCDWR mitigation requirement is 1.23
acres at 2:1 ratio. The NCDWR wetland mitigation requirement exceeds the USACE
requirement. The mitigation requirements of 1.20 acres of permanent riparian wetland impacts
and 0.03 acres of permanent non- riparian wetland impacts will be provided by the NCEEP for
R -0623 (Table 3).

Dear Mr. Hancock:
Subject: EEP Mitigation Acceptance Letter:
R -0623, Troy Bypass — NC 24 / 27 from SR 1138 (Dairy Road) to East of the Little River, Montgomery
County
The purpose of this letter is to notify you that the Ecosystem Enhancement Program (EEP) will provide the
compensatory stream and wetland mitigation for the subject project. Based on the information supplied by you on July 25,
2014, the impacts are located in CU 03040104 of the Yadkin River basin in the Southern Piedmont (SP) Eco- Region, and are
as follows:

*Some of the stream and wetland impacts may be proposed to be mitigated at a 1:1 mitigation ratio. See permit application
for details on the mitigation ratio proposal. EEP is proposing to provide riparian wetland mitigation for all wetland impacts
associated with this project.
This mitigation acceptance letter replaces the mitigation acceptance letters issued on February 25 and March
7, 2014. In accordance with the directive from the February 8, 2011 IRT meeting, non - riparian wetland impacts located in the
mountains and piedmont areas of North Carolina will be accepted as requested but mitigated utilizing riparian wetland
mitigation credits. EEP commits to implementing sufficient compensatory warm stream mitigation and riparian wetland
mitigation credits to offset the impacts associated with this project as determined by the regulatory agencies in accordance
with the N.C. Department of Environment and Natural Resources' Ecosystem Enhancement Program 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 EEP.
If you have any questions or need additional information, please contact Ms. Beth Harmon at 919- 707 -8420.
Sincerely,
JamtAssetanagemeni
