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 widening, improve and pave Mountain Trail Rd in Alamance County.
• 116 linear feet of new piping impacts to three unnamed tributaries to Cane Creek (56 feet of new pipe impacts and 60
feet of rip-rap impacts); and
• Temporary dewatering impacts of approximately 50 square feet at each location.
The project shall be constructed in accordance with your application dated April 17, 2006 and additional information
dated received June 2, 2006. 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 respectively. 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 federal permit. This condition supercedes
condition No. 19 in the General Certification 3404, and condition No. 12 in General Certification 3366.
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.

IX. 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 NC`'VRP 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
littp://h2o.enr.state.ne.us/ncwetiands/strni,Ride.litnil.
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 approximately 19 linear feet No Outstanding Resource Waters federally protected
species or their habitats or essential fishery habitats occur in the project area. The project is

Construction Sequence and Erosion Control Plan for Replacement of
Pipe with Pipe Using a Pump Around - Alamance County, Mountain
Trail Road
Work to begin as soon as practicable following authorization.
Construction is anticipated to take 2 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 existing line pipe.
5. Excavate to sufficient depth to allow burial at a minimum depth of one foot or 20 %
of the pipe diameter.
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. If necessary, 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.
