Dear Mr. Mills:
You have our approval, in accordance with the attached conditions and those listed below, to place permanent fill
material in 20 linear feet, 20 linear feet of temporary fill, and 20 linear feet of rip rap for the purpose of widening
and paving of SR 1107 in Alamance County. The project shall be constructed in accordance with your application
dated July 29, 2002. After reviewing your application, we have decided that this fill is covered by General Water
Quality Certification Number 3375. This certification corresponds to the Nationwide Permit 14 issued by the Corps
of Engineers. In addition, you should acquire any other federal, state or local permits before you proceed with your
project including (but not limited to) Sediment and Erosion Control, Non-Discharge and Water Supply Watershed
regulations. This approval will expire with the accompanying 404 permit, unless otherwise specified in the Water
Quality Certification.
This approval is valid solely for the purpose and design described in your application (unless modified below).
Should your project change, you must notify the DWQ and submit a new application. If the property is sold, the
new owner must be given a copy of this Certification and approval letter, and is thereby responsible for complying
with all the conditions. If total wetland fills for this project (now or in the future) exceed one acre, or of total
impacts to streams (now or in the future) exceed 150 linear feet, compensatory mitigation may be required as
described in 15A NCAC 211.0506 (h) (6) and (7). For this approval to remain valid, you must adhere to the
conditions listed in the attached certification.
1.) Upon completion of the project, the NCDOT shall complete and return the enclosed "Certification of
Completion Form" to notify DWQ when all work included in the 401 Certification has been completed. The
responsible party shall complete the attached form and return it to the 401Wetlands Unit of the Division of
Water Quality upon completion of the project.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must
act within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition that conforms
to Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, P.O. Box 27447,

Practices for the protection of wetland and surface waters restrictions against the staging of
equipment in or adjacent to waters of the US, and coordination (including a pre-construction
meeting) with the Division Environmental Officer.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
1'<igc 5 of 8
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetlands/strmizlde.html.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
A finding of insignificant impact is anticipated; therefore, a mitigation plan is not provided.
Cumulative impacts are less than 150 feet. The maximum amount of impact to a single
stream is 40 linear feet. No Outstanding Resource Waters, federally protected species or
their habitats, or essential fishery habitats occur in the project area. The project is not located
in a High Quality Water.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
(919) 733-5208 to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the
following information:

Construction Sequence and Erosion Control Plan for Replacement of
Pipe with Pipe Using a Diversion - Alamance County, SR 1107
Work to begin as soon as practicable following authorization.
Construction is anticipated to take 4 weeks.
1. Prior to beginning pipe removal and installation, drill holes and place supporting bolts
in one end of a single line of 60' long 117" X 79" CM pipe arch.
2. nstall a rock silt dam downstream of the proposed diversion channel outlet to prevent
incidental sediment loss from the diversion channel.
3. Dig a diversion channel to dewater the construction area. The diversion channel will
be approximately the same width as the existing channel.
4. Line the diversion channel with poly-fabric to prevent sediment loss.
5. Install ABC aggregate or a less intrusive dewatering device to force flow into the
diversion channel.
6. Breach the inlet and outlet dams of the diversion channel.
7. Remove one existing line of 40' long 72" CM pipe.
8. Excavate to sufficient depth to allow burial of the pipes to 1', place base stone, and
two lines of 60' long 117" X 79" CM pipe arch.
9. Backfill the new lines of pipe and place rip rap only as needed.
10. Prior to removing the diversion place cofferdams to divert flow into the pipe without
the sill.
11. Starting from the downstream end, remove the dewatering structure and restore the
natural stream contours.
12. Place ABC aggregate at each end of the diversion channel forcing flow through the
pipe without the sill.
13. Dewater the diversion channel, backfill with suitable material, and compact the
backfilled material.
14. Construct mold and pour concrete sill in the appropriate line of pipe.
15. Following setting of the concrete sill remove the cofferdams.
16. Notify landscape department for final seeding.
17. Silt fences to be placed as site conditions require.
18. A 10' X 15' dirt bag will be used to remove excess water in the hole where the new
pipe is being replaced.
19. Site conditions and weather may alter these plans.
20. A pump around system or rock silt screen may be utilized in place of a diversion
channel if conditions allow.
