SUBJECT: Revision to On-hold Letter Response for Section 401 Water Quality
Certification and Jordan Lake Watershed Riparian Buffer Authorization
Application for the replacement of Bridge No. 161 over North Prong Stinking
Quarter Creek on SR 1124 (Stafford Mill Road), Alamance County, North
Carolina. Federal Aid Project No. BRZ — 1124 (5), TIP No. B-4401.
REFERENCE: 1) N.C. Ecosystem Enhancement Program Mitigation Acceptance Letter, dated
February 19, 2013.
2) Application for Section 401 Water Quality Certiiication and Jordan Lake
Watershed Riparian Buffer Authorization and Notice of Intent to Use Section
404 Nationwide Permits 3 and 13, dated February 20, 2013.
3) NCDWQ On-hold Letter, dated February 25, 2013.
4) Revised N.C. Ecosystem Enhancement Program Mitigation Acceptance
Letter, dated March 12, 2013.
5) NCDOT Response to NCDWQ On-hold Letter, dated March 15, 2013.
Per your comments via email and phone correspondence regarding the N.C. Department of
Transportation's (NCDOT) March 15, 2013 response to the N.C. Division of Water Quality's
(NCDWQ) on-hold letter, NCDOT has revised the permit application packet to address the issues
that you had identified. Revisions include the following:
• The Stormwater Management Plan (SMP) has been updated to sufficiently discuss the
stormwater design of the project and to provide additional information about both the
existing and proposed stormwater ditches.
• The buffer drawings were revised because, after NCDWQ was supplied with complete
information regarding the existing and proposed stormwater ditches, it was determined

that the buffer impacts resulting from the two proposed lateral base ditches should be
considercd "Allowable". Therefore, the portions of the ditches that run through the
`Bcidge" buffer impact zone were ceverted baek to being natched "Allowable° and these
impacts wcre listed separately on the Buffer Impact Summary Shcct. 'I'he impacts from
the ditches where thcy run through the "Road Crossing" buffer impact zone are
superseded by the "Mitigable° Road Crossing impacts; therefore, those impacts were
included as Road Crossing and no ditch impacts are shown or calculated for those
portions of the ditches.
The Pre-Construction Notification (PCN) has becn updated to reflect these changes.
Due to the abovc changes to the buffer impac[s, the amount of buffer mitigation required
has been reduced from the numbers provided in our on-hold response packet and the N.C.
Ecosystem Enhancement Peogram (EEP) revised Mitigation Accepta�ce Letter. 7'he
buffer mitigation required has reverted back to the numbers presented in the original
permit applicatio� and the o�iginal EEP Mitigation Acceptance Lettec Please refer to the
original EEP Mitigation Acceptance Letter when reviewing this packet. NCDO"I' is
coordinating with EEP.
The wetland and stream permit drawings and the impacts presented in them have not changed
since the submission of the original permit application.
Please find enclosed revised versions of thc PCN, SMP, and buffer drawings and a copy of the
original EEP Mitigation Acceptance Letter. We believe that this new informaAOn addresses all of
your concems regarding the project and respectfully request that you proceed with processing the
permit application.
A copy of this revision to [he on-hold response packet will be posted on the NCDOT Website aC

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
An off-site detour will be employed; A special cut ditch with a Class B rip-rap pad at its terminus will be installed between

ditch underlain with filter fabric will be installed between STA. 16+40 and STA. 18+50 LT. At the ditch's origin will be a an
18-inch reinforced concrete pipe; at its terminus will be Class I rip-rap underlain with filter fabric starting at the end of the
ditch and extending to/onto the streambank; A PSRM-lined lateral base ditch will be installed between STA. 16+90 and
STA. 17+40 RT.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
NCDOT Best Management Practices for Bridge Demolition and Removal will be implemented during the removal of the
existing bridge; Best Management Practices for the Protection of Surface Waters will be employed; Additionally, since this
project is located within the Jordan Lake Watershed and buffer rules apply, Design Standards in Sensitive Watersheds
will be employed.

Dear Dr. Thorpe:
Subject: EEP Mitigation Acceptance Letter:
B-4401, Replace Bridge Number 161 over North Prong Stinking Quarter Creek on SR 1124
(Stafford Road), Alamance County
The purpose of this letter is to notify you that the Ecosystem Enhancement Program (EEP) will
provide the buffer initigation for the subject project. Based on the information supplied by you on February
15, 2013, the buffer impacts are located in CU 03030002 of the Cape Fear River basin (Haw Ann) in the
Central Piedmont (CP) Eco-Region and are as follows:
Buffer Impacts (in square feet)
Buffer River Basin CU Location Eco-Region
Zone i Zone 2 TOTAL
Impacts CapeFear— 03030002 CP 305.0 3,138.0 3,443.0
Haw Ann
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 NCDWQ's Buffer Authorization
Certiflcation, EEP 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 TIP number B-4401. Subsequently, EEP will conduct a review of current NCDOT ILF
Program initigation projects in the river basin to determine if available buffer mitigation credits exist. If there
are buffer initigation credits available, then the Riparian Restoration Buffer Fund will purchase the appropriate
amount of buffer mitigation credits from NCDOT ILF Prograin.
If you have any questions or need additional infonnation. please contact Ms. Beth Hannon at 919-
707=8420.
