Dear Mr. Mills:
You have our approval, in accordance with the attached conditions and those listed below, to incur the following impacts
in order to replace an undersized pipe on SR 1826 (Dilworth Rd) in Guilford County.
• 20 linear feet of piping impacts;
• up to 20 linear feet of rip rap for bank stabilization; and
• Temporary dewatering impacts of approximately 50 linear feet at each location.
This project has been determined to be exempt from the Randleman Lake Water Supply riparian area protection
requirements per 15A NCAC .02B .0250(2)(e).
The project shall be constructed in accordance with your application dated April 4, 2005. After reviewing your
application, we have decided that this fill is covered by General Water Quality Certification Nos. 3495, 3404 and 3366,
corresponding to the U.S. Army Corps of Engineers Nationwide Permit Numbers 13, 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 completion of 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 chance 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.

Subject: Dilworth Rd (SR 1826) - Guilford County, Pipe Replacement
State Project Number 33295.1.1
To Whom It May Concern:
The North Carolina Department of Transportation (NCDOT) proposes to replace an undersized pipe on
Dilworth Road in Guilford County, north of High Point, with a larger pipe. This activity will result in
impacts to an UT to the West Fork of Deep River. This project is in the Randleman Lake Water Supply
Watershed. However, DOT is requesting to utilize the "No Practical Alternative" option (15A NCAC
02B.0250 (2) (e) in order to complete the project. It is the department's opinion that the project has
been designed to have minimal disturbance, to provide maximum nutrient removal and erosion
protection, to have least adverse effects on aquatic life and habitat, and to protect water quality to the
maximum extent practical through the use of best management practices: The road will be closed
during construction with offsite detours. The NCDOT anticipates that the pipe replacement activity and
extension will be authorized under Nationwide Permits (NWP) 13, 14 and 33. This application is
intended as a request for written authorization from the US Army Corps of Engineers for the
Nationwides 13, 14 and 33. This package is also being forwarded to the NC Division of Water Quality
notification as prescribed under General Water Quality Certifications #3399 (NW 13), #3404 (NW 14)
and #3366 (NW 33). The following information is being provided to satisfy conditions of the
Nationwide Permits and General Water Quality Certifications.

Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
Pipe replacement activities are necessary to maintain travel safety. Impacts will be minimized
by strict enforcement of Best Management 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
Page 5 of 8
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
larking 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/ncwet]ands/strmgide.htm1.
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 approximately 20 linear feet. No Outstanding Resource Waters, federally protected
species or their habitats, or essential fishery habitats occur in the project area.

Construction Sequence and Erosion Control Plan for Pipe Replacement
Guilford County - Dilworth Road - SR 1826
1. Install a rock silt dam (underlain with filter fabric) downstream of work area to prevent
incidental sediment loss.
2. Install ABC aggregate or a less intrusive dewatering device to allow dewatering of work area.
3. If necessary install pumps to divert flow around work area.
4. Remove one existing line of 40' x 60" CMP.
5. Excavate to sufficient depth to allow l' burial of pipe replacement, place bass stone and
install single line of 60' x 95" x 67" CSPA.
6. A 10' X 15' siltbag will be used to remove any excess water in work area.
7. Backfill new pipe and place rip rap for bank stabilization, if necessary.
8. Silt dams removed from downstream end then upstream end with natural stream contour
restoration.
9. Notify landscape department for final seeding.
10. Silt fences to be placed, as site conditions require.
11. A less obtrusive method than a pump around system may be utilized if site conditions allow.
12. Site conditions and weather may alter these plans.
