Mr. J.M. Mills, P.E.
Division Engineer, Division 7
North Carolina Department of Transportation
1584 Yanceyville Street
Greensboro, North Carolina, 27415
Dear Mr. Mills:
JUN 0 3 2004
WATER QUALITY SECTION
You have our approval, in accordance with the attached conditions and those listed below, to impact 40
linear feet of an unnamed tributary to Rock Creek (20 feet of new pipe and 20 feet of rip-rap) in order to
pave, increase lane width and improve traffic safety on SR 1126 (Isley Rd.) in Alamance County. The
project shall be constructed in accordance with your application dated May 4, 2004 (received May 6,
2004).
After reviewing your application, we have decided that this fill is covered by General Water Quality
Certification Nos. 3404 and 3366, corresponding to the U.S. Army Corps of Engineers Nationwide Permit
Numbers 14 and 33. 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 Division of Water Quality (Division) and
submit a new application. If the property is sold, the new owner must be given a copy of this approval
letter and certifications, 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 if total impacts to streams (now or in the
future) exceed 150 linear feet, compensatory mitigation may be required as described in 15A NCAC 2H
.0506 (h) (6) and (7). For this approval to remain valid, you must adhere to the conditions listed in the
attached certification and any additional conditions listed below.
Erosion and sediment control practices must be in full compliance with all specifications
governing the proper design, installation and operation and maintenance of such Best
Management Practices in order to protect surface waters standards:
a. The erosion and sediment control measures for the project must be designed, installed,
operated, and maintained in accordance with the most recent version of the North Carolina
Sediment and Erosion Control Planning and Design Manual.

b. The design, installation, operation, and maintenance of the sediment and erosion control
measures must be such that they equal, or exceed, the requirements specified in the most
recent version of the North Carolina Sediment and Erosion Control Manual. The devices
shall be maintained on all construction sites, borrow sites, and waste pile (spoil) projects,
including contractor-owned or leased borrow pits associated with the project.
c. For borrow pit sites, the erosion and sediment control measures must be designed, installed,
operated, and maintained in accordance with the most recent version of the North Carolina
Surface Mining Manual.
d. The reclamation measures and implementation must comply with the reclamation in
accordance with the requirements of the Sedimentation Pollution Control Act.
2. No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the
footprint of the impacts depicted in the Preconstruction Notice Application. All construction
activities, including the design, installation, operation, and maintenance of sediment and erosion
control Best Management Practices, shall be performed so that no violations of state water quality
standards, statutes, or rules occur.
3. Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum
extent practicable. If placement of sediment and erosion control devices in wetlands and waters is
unavoidable, they shall be removed and the natural grade restored within six months of the date that
the Division of Land Resources has released the project.
4. Riparian vegetation must be reestablished within the construction limits of the project by the end of
the growing season following completion of construction.
5. Stormwater should be directed to vegetated buffer areas, grass lined ditches or other means
appropriate to the site for the purpose of pre-treating stormwater runoff, and must not be routed
directly into streams. Mowing of existing vegetated buffers is strongly discouraged, so that they may
be utilized for stormwater sheet flow.
6. Where practicable, culverts that are less than 48-inch in diameter should be buried to a depth equal to
or greater than 20% of their size to allow for aquatic life passage. Culverts that are 48-inch in
diameter or larger should be buried at least 12 inches below the stream bottom to allow natural stream
bottom material to become established in the culvert following installation and to provide aquatic life
passage during periods of low flow. These measurements must be based on natural thalweg depths.
This may require increasing the size of the culvert to meet flow conveyance requirements. If any of
the existing pipes are perched, they shall be removed and replaced, and re-installed correctly, unless
demonstrated that this is topographically unfeasible. All waters must flow through without freefalling
or damming on either end of the culverts during low flow conditions, to maintain aquatic life and/or
fish passage.
7. The dimension, pattern and profile of the stream above and below the crossing should not be modified
by widening the stream channel or reducing the depth of the stream.
8. Disturbed floodplains and streams should be restored to natural geomorphic conditions.
9. Use of rip-rap for bank stabilization is to be minimized; rather, native vegetation is to be planted
when practical. If rip-rap is necessary, it must be limited to the stream bank below the high water
mark, and vegetation must be used for stabilization above high water. Any rip-rap used must not
interfere with aquatic life passage during low flow conditions.
10. If concrete is used, work must be accomplished so the wet concrete does not contact the stream water.
This will lessen the change of altering the stream's water chemistry and causing a fish kill.
11. Heavy equipment must be operated from the banks rather than in the stream channel in order to
minimize sedimentation and reduce the likelihood of introducing other pollutants into the stream.
12. All mechanized equipment operated near surface waters must be regularly inspected and maintained
to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic
materials.

13. The presence of equipment in the channels must be minimized. Under no circumstances must rock,
sand or other materials be dredged from the wetted stream channel under authorization of this permit,
except in the immediate vicinity of the culverts.
14. Temporary dewatering sites must be restored to preexisting conditions unless more natural
geomorphic conditions can be provided.
15. All work shall be performed during low flow conditions.
16. 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 401 /Wetlands
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, which conforms to Chapter 150B of the North Carolina General Statutes to the Office of
Administrative Hearings, 6714 Mail Service Center, Raleigh, N.C. 27699-6714. This certification and its
conditions are final and binding unless you ask for a hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water
Act. If you have any questions, please contact Sue Homewood at 336-7714600 extension 252 or at
[e-mail].

SUBJECT: Alamance County, Replacement of culvert on Isley Road (SR 1126) crossing an
unnamed tributary of Rock Creek. W.O. Number 7C.001045
To Whom It May Concern:
The North Carolina Department of Transportation (NCDOT) proposes to replace a culvert on Isley
Rd (SR 1126). The proposed work is being done in conjunction with a secondary road paving
project in order to reduce future maintenance needs and increase traffic safety. This activity will
result in impacts to a UT of Rock Creek. The NCDOT anticipates that the pipe replacement activity
will be authorized under Nationwide Permit (NWP) 14 and 33. This application is intended as a
request for Nationwides 14 Ind 33 from the US Army Corps of Engineers. We are also requesting
written authorization from NC Division of Water Quality to replace the pipes under General Water
Quality Certificate # 3404 (NWP 14) and notification under #3366 (NWP 33). The following
information is being provided to satisfy Condition 1 of General Water Quality Certificate # 3404 and
#3366.

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.
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.ne.us/iicwetlands/strmgide,litml.
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 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) with the NCWRP's written agreement. Check the box indicating that
you would like to pay into the NCWRP. Please note that payment into the NCWRP must be
reviewed and approved before it can be used to satisfy mitigation requirements. Applicants
will be notified early in the review process by the 401/Wetlands Unit if payment into the
NCWRP is available as an option. For additional information regarding the application
process for the NCWRP, check the NCWRP website at thttp:020.enr.state.nc.us/wm/index.htn,. If
use of the NCWRP is proposed, please check the appropriate box on page three and provide

Construction Sequence and Erosion Control Plan for Replacement of
Pipe with Pipe Using a Pump Around - Alamance County, Isley Road
SR 1126
Work to begin as soon as practicable following authorization.
Construction is anticipated to take 4 weeks.
1. Install a rock silt dam downstream of the work area to prevent incidental sediment
loss.
2. Install ABC aggregate or a less intrusive dewatering device to allow dewatering of
the work area.
3. Install pumps to divert flow around the work area.
4. Remove one existing line of 40' long X 48" pipe.
5. Excavate to sufficient depth to allow burial at a minimum depth of 9.6 inches, place
base stone, and single line of 60' long X 48" pipe.
6. Backfill the new line of pipe and place rip rap only as needed.
7. Starting from the downstream end, remove the dewatering device and restore the
natural stream contours.
8. Notify landscape department for final seeding.
9. Silt fences to be placed as site conditions require.
10. A 10' X 15' dirt bag will be used to remove excess water in the hole where the new
pipe is being replaced.
11. Site conditions and weather may alter these plans.
12. A method less intrusive than a pump around system may be utilized if site conditions
allow.
