APPROVAL of 401 Water Quality Certification
Dear Mr. Gray:
You have our approval, in accordance with the attached conditions, to place fill in 140 linear feet of streams and to flood 820 linear
feet of streams in order to create a farm pond on your property in Iredell County, as described in your application received by the Division
of Water Quality on November 1, 2002. After reviewing your application, we have determined that this fill is covered by General Water
Quality Certification Number 3362, which can be downloaded from our web site at http://h2o.enr.state.nc.us . This Certification allows you
to use Nationwide Permit Number 39 when it is issued by the U.S. Army Corps of Engineers. In addition, you should get any other
federal, state or local permits before you go ahead with your project including (but not limited to) Sediment and Erosion Control, Non-
Discharge and Water Supply Watershed regulations. You should send an application to the Division of Land Resources for their review of
your project under dam safety rules as well as erosion and sediment control. Also this approval will expire when the accompanying 404
permit expires unless otherwise specified in the General Certification.
This approval is only valid for the purpose and design that you described in your application. If you change your project, you must
notify us in writing and you may be required to send us a new application for a new certification. If the property is sold, the new owner
must be given a copy of the Certification and approval letter and is thereby responsible for complying with all conditions. If total wetland
fills for this project (now or in the future) exceed one acre, compensatory mitigation may be required as described in 15A NCAC 2H .0506
(h). For this approval to be valid, you must follow the conditions listed in the attached certification and the additional condition listed
below:
1. You are required to return the attached Certification of Completion form to notify DWQ when all work included in the 401 Certification has
been completed.
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 telephone Alan Johnson in DWQ's Mooresville Regional Office at 704-663-1699 or Cyndi Karoly in Raleigh at 919-733-
9721.
Sincerely,

Comments:
The applicant has rete sted that a dam be constructed for the purpose of establishing a 3 acre farm
pond, Because this farm (dairy) meets the requirements as a concentrated feedlot, it is inspected
annually by this office, T he stream to be impacted is located in a pasture. There are no wetlands.
The clam has been desig ned by the Soil and Water Conservation District Engineer. The footprint of
the dam in the stream is to be 140 ft, or less. The 960 ft_ stated in the application includes the length
of stream channel "impa cted" from flooding. The Soil and Water staff have been informed to contact
the Corp of Engineers re garding tthe_project. No problems are anticipated.

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.
Page 9 of 12
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
httu://h2o.enr.state.nc.us/ncwetlands/strmgide 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.
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 NCWR.P, check the NCWRP website at ba.//h2o.enr.state nc us/wWriindex htm. If
use of the NCWRP is proposed, please check the appropriate box on page three and provide
the following information:
Amount of stream mitigation requested (linear feet):
Amount of buffer mitigation requested (square feet):
Amount of Riparian wetland mitigation requested (acres):
Amount of Non-riparian wetland mitigation requested (acres):
Amount of Coastal wetland mitigation requested (acres):

RE: Approval to Construct
J. Reid Gray Farm Pond Dam
Iredell County
Yadkin-Pee Dee River Basin
Dear Mr. Gray:
This letter is in response to plans, specifications and design data submitted
under transmittal letter dated April 8, 2002 and received by this office on June 5,
2002 for the construction of the referenced dam, which is located on a tributary to
Buffalo Shoals Creek in Iredell County. These plans and specifications were
prepared under the supervision of Mr. Samuel C. Bingham, PE, with the Natural
Resource Conservation Service. Also, check number 5981 for $200.00 was
received as the initial plan review fee.
This letter constitutes approval of your proposal to construct the subject dam
according to the plans and specifications received by this Division on June 5,
2002 with the following stipulations:
1. The Natural Resources Conservation Service shall supervise the project
construction.
2. During construction the Division of Land Resources may require such
progress reports as are deemed necessary.
3. Upon completion of the project, The Natural Resource Conservation
Service shall inspect the completed work and upon finding (a) that the
work has been done as specified, and (b) that the dam is safe, shall file
with the Division of Land Resources two sets of "as-built" drawings and a
certificate stating that the work has been completed in accordance with
the approved plans, specifications and other requirements.

4. Applicable NRCS (SCS) standards for the installation of seepage
diaphragms for conduits through dams shall be met.
6. Stream flow shall be piped or otherwise diverted around or through the
construction site without being contaminated with sediment.
7. The North Carolina Division of Water Resources has determined that this
project is subject to NC Administrative Code 15A 2K .0500 Minimum
Stream Flows to Maintain Aquatic Habitat. The project is under study by
the Division of Water Quality (DWQ) to locate any existing point
discharges downstream and determine if a minimum release will be
required. When the Division of Land Resources receives a determination
from DWQ, stipulations reflecting it may be included in the permit to
impound or subsequent amendments.
8. Land disturbing activities in the impoundment area shall be limited to
those necessary for construction of the dam until a permit to impound is
issued and impoundment begins such that sediment will be retained in the
impoundment.
8. You must notify Mr. G. Douglas Miller, PE, Regional Engineer, Land
Quality Section, 919 North Main Street, Mooresville, North Carolina
28115, and telephone number [phone], ten days before the start of
construction.
In addition, we suggest you contact the US Army Corps of Engineers to
determine if a Section 404 permit will be required. Also, the Water Quality
Division of this Department may require a Section 401 permit.
I am enclosing a copy of a cost certification form and an explanation of the final
processing fee calculation. An additional fee will be required when the engineer's
certification is submitted if the construction cost exceeds $10,001.00. In any
event, the cost certification must be completed and returned with the engineer's
certification before an approval to impound can be processed.
Mr. Gray
September 23, 2002

The Dam Safety Law of 1967 requires that project construction commence within
one year from the date of this approval, or the approval is void.

NOTE: This specification is intended to give guidance in ~
controlling erosion while installing this practice.
EROSION AND SEDIMENT CONTROL MEASURES
Erosion and sediment control measures shall include the following:
a. Staging of Farth Work Activitlela
The excavation and moving of soil materials shall be
scheduled so that the smallest possible areas will be bare
and unprotected from erosion for the shortest time feasible.
Construction Sequence
1. Clear Embankment and spillway Site
2. Complete cutoff trench on Right Abutment nearly to Stream
3. Construct coffer dam upstream of dam to block water
4. Complete cutoff trench across stream and leave temporary
channel for stream flow
5. Remove Coffer Dam
6. Complete rest of Cutoff Trench
7. Construct Principal Spillway Trench
8. Lay pipe
9. Construct Riser and Plunge Pool
10. Construct Drainage Diaphragm and backfill at least 2
feet over pipe
11. Turn stream flow through pipe
12. Construct dam and emergency spillway
13. Complete seeding
14. Clear pool area
b. Con rn1 of Sediman frnm Oitnff Tr nrh Dpwatp-ring
Sediment from dewatering shall be controlled by ponding water
in flood plain below dam or pumping water into an excavated
pit.
C. DiV rRlon4
Diversions shall be used to divert water away from disturbed
areas and also located as needed to provide optimum erosion
control during vegetative establishment period. An example
is a diversion located uphill of a borrow area slope. A
typical diversion is 1.5 ft deep and shaped to easily mow.
The Natural Resources Conservation Service will determine
location of diversions.
d. Vage a ion
within 7 days of final grading, vegetative work shall be
completed.

SPECIFICATIONS FOR CONSTRUCTION OF PONDS AND RESERVOIRS
Clearing: All trees and brush shall be removed from the impoundment area before any water is -
impounded. Whenever practical, this clearing should be delayed until after the dam is built to
hold erosion and downs tream-sedimentation to a minimum. Studs may be removed or trees may be -
sawed off as low as practical and stumps left standing.
The foundation of the impoundment structure (dam) shall be cleared of all trees,
stumps, roots, brush, sod, and debris. All stumps and all roots exceeding one (1) inch in
diameter shall be removed to a minimrm depth of one (1) foot. Satisfactory disposition will
be made of all debris.
After clearing is completed the foundation area shall be loosened thoroughly and
roughly leveled, with suitable equipment, before placement of any embankment material.
Cutoff Trench: A cutoff trench shall be excavated as shown on the plans. The cutoff trench
shall be backfilled in thin layers, not to exceed 8 inches in depth. All standing water shall
be removed from the trench before backfilling is started.
Embankment Construction: The material placed in the embankment shall be free of sod, roots,
stones over 6 inches in diameter, and other objectionable materials. The fill material shall
be placed and spread over the entire fill in layers not to exceed 8 inches in thickness. Con-
struction of the fill shall be undertaken only at such times that the moisture content of the
fill material will permit a reasonable degree of compaction.
Fill Materials: Borrow areas will be designated on the plans and assigned priority (1, 2, 3,
etc.). All fill material shall be taken from these designated areas. SCS technicians will
advise the contractor regarding the maximum depth of cut in each borrow area. The contractor
will not exceed this depth. In the event this depth is exceeded in the impoundment area, it
shall be the responsibility of the contractor, without additional" cost to the landowner, to
cover the exposed area with a minimum of 2 feet of impervious material.
Riser b Conduit Pipe: When it is indicated on the plans that a riser and conduit pipe are re-
quired, they must be installed as a complete unit. The inlet of the riser shall be protected.
by an inverted bucket-type, or an equally effective type, of trash rack. The conduit shall be
placed on a firm foundation. Selected backfill material shall be placed around the riser and
conduit pipe in layers not exceeding 4 inches and each successive layer thoroughly compacted.
Anti-Seep Collars:. Anti-seep collars will be of materials and dimensions, and located as shown
in the plans where specified.
Vegetated Spillwav(s): Spillway(s) will be excavated in undisturbed earth to the dimensions,
grades, slopes, and location as shown in the plans and as staked upon the ground.
Pollution Control During Construction: Stripping of embankment and borrow areas shall be dole
as they are needed in a normal sequence of construction. Use temporary mulch protection on all
disturbed areas that are subject to erosion and will not have substantial additional work per-
formed for 30 days or more. Temporary stream crossing structures will be used where fording of
streams will cause excessive sediment pollution. Protection against pollutants such as
chemicals, fuel, lubricants, sewage. etc., will be provided during construction.
Vegetation: All exposed embankment. spillway, and borrow area shall be seeded to an adapted
type of vegetation as soon as possible after construction.
Special Provisions:

CONSTRUCTION SPECIFICATION
FABRIC FILTER CLOTH - -
1. SCOPE
This work shall consist of furnishing all materials, equipment and
labor necessary for the installation of geotextile fabric filter
cloth under rock riprap and as a load stabilizer under surfacing
materials on roadbeds and other heavy use areas.
2. MATERIALS
Fabric filter cloth shall be manufactured from synthetic long chain
or continuous polymeric filaments or yarns such as polypropylene,
polyethylene, polyester, polyamide, or polyvinyl idene -chloride. The
fabric filter cloth shall. be formed into a stable network of
filaments or yarns that retain their relative position to each
other, are inert to commonly encountered chemicals, and are
resistant to ultraviolet light exposure, heat, hydrocarbons, mildew,
rodents and insects. The fabric filter cloth shall be free of any
chemical treatment or coating that might significantly reduce its
permeability and shall have no flaws or defects that would
significantly alter its physical properties.
Fabric filter cloth shall be of the. non-woven type and shall conform.
to the physical properties listed in Table 1, based on the average
roll minimum value. Non-woven fabric filter cloth shall be
manufactured from randomly oriented fibers bonded together by the.
needle punched process.
Prior to installation of any fabric filter cloth, the Contractor
shall furnish the Contracting Officer the following information:
(1) Name of product and manufacturer.
(2) Product description, chemical composition, and copies of
typical laboratory test values.
(3) Statement of compliance attesting that the fabric filter
cloth meets the chemical, physical, and manufacturing

S . PLACEMENT
The fabric filter cloth shall be placed on the approved prepared
surface at the locations and in accordance with the details shown on
the drawings. The fabric shall be unrolled along the placement area-
and loosely laid (not stretched) in such a manner that it will
conform to the surface irregularities when the stone or other
material is placed on it. No cuts will be permitted in the fabric
panel unless otherwise specified. The panel may be folded and
overlapped to permit proper placement in the designated areas.
The orientation of the width and length of the fabric panels shall
be as shown on the drawings. The fabric length shall be placed
parallel to the direction of water flow unless otherwise indicated
on the drawings. The overlaps of panels and end roll details shall
be as specified. The minimum overlap shall be 18 inches.
Securing staples shall be placed along the edge of the panel and at
abrupt changes in contour to adequately secure the fabric filter
cloth to the soil surface. At overlaps, securing staples shall be
inserted through both layers along a line through the approximate
midpoint of the overlap. Securing pins shall be placed along a line
approximately two inches in from the edge of the outer limits of the
completed filter cloth area at intervals not greater than 12 feet.
Additional staples shall be installed as necessary to prevent any
slippage of the fabric, regardless of location. Staples shall be
machine made of No.-11 gauge or larger new steel wire formed into a
"U" shape. The size when formed shall not be less than 6-inches.in
length with a throat of not less than 1 inch in width. Staples
normally used for securing erosion control netting may be acceptable

Laying the Ductile Iron Pipe
The pipe conduit shall be placed on a firm foundation to the
lines and grades shown on the plans. Installation shall be
performed in a skillful and workmanlike manner in accordance
with the manufacturer's recommendations and the following
requirements.
The contractor may elect to overfill the conduit foundation
and the adjoining area prior to laying the pipe. The amount
of overfill will be limited to two feet vertically above the
planned pipe grade. Excavations for the conduit trench
shall have a minimum bottom width of four feet with 3:1 or
flatter side slopes.
Prior to laying the pipe, a bedding trench shall be prepared
for the pipe by filling approximately two inches above grade
with a compacted material. The foundation area for the pipe
shall then be excavated to approximately one inch below the
planned invert elevation for the pipe. As it is critical
that this area is properly shaped to conform to the pipe,
the shaping shall be performed by hand unless the engineer
approves an alternative method. Also, a template equivalent
to the outside diameter of the pipe (with screed), shall be
used to check the shaped area to insure that it conforms to
the pipe diameter.
One inch of select impervious moist material shall be placed
in the shaped bedding trench immediately prior to placing
the pipe.
The pipe shall then be placed to line and grade and firmly
and uniformly bedded in the bedding trench throughout its
entire length with select impervious moist fill material.
The area supporting the joints shall be over excavated as
necessary to allow for assembly and to insure that the pipe
barrel is uniformly supported by the soil bedding. Select
moist backfill material shall be placed and hand compacted
around the pipe conduit at approximately the same rate on
both sides of the pipe. Compaction around the bottom half
of the pipe must be firm to fill all voids, but extreme
caution must be exercised to prevent damage, movement,
uplift or defection of the pipe.

GRAY'S FARM POND
VEGETATION ESTABLISHMENT -
Grading and Shaping
Construct diversions above spillway cut slopes to prevent run off from draining across the
side slopes. NRCS Conservationist will make final construction inspection before
seedbed is prepared.
Seedbed Preparation
Rip and disk all disturbed areas 6" deep. Incorporate 3 tons of lime, 1000 lbs. of 10-10-
10 and 500 lbs of 0-20-0 into the soil. Uniformly apply 50 lbs. tall fescue per acre.
Seeding should be completed as soon as possible after construction. Immediately (same
day) mulch with 100 bales of small grain straw per acre. Reseed any tilled or gullied
areas that may develop. A nurse crop should be seeded with fescue. NRCS will
determine whether cool season (25 lbs. rye grain/acre) or warm season (sudex sedan)
nurse crop is needed.

What Is a Critical
Erosion Area?
A critical erosion area is any erod-
ing, sediment-producing area such
as excessively eroding cropland,
cuts, fills, streambanks, landfills,
roadbanks, dams, spillways, bor-
row areas, and denuded or gullied
areas where vegetative stabilization
is difficult by ordinary methods.
Erosion Ar
Permanent Ground
Cover
United States Department of Agriculture
Soil Conservation Service
Raleigh, North Carolina
Stabilizing these areas will reduce
damage from sediment and runoff
to downstream areas, and improve
wildlife habitat and visual resources
Soils
Usually the soil material on which
seeding or planting is to be done is
infertile, poor in structure and ag-
gregation, low in organic matter
and may be highly acid. This ma-
terial is highly susceptible to ero-
sion due to slow water intake and
rapid runoff. To aid in overcom-
ing these conditions, organic mat-
ter can be applied in the form of
manure, lime applied where
needed, and appropriate commer-
cial fertilizers added. On most
sites, four inches of loamy topsoil
applied to the site before seeding

OPERATIONS AND MAINTENANCE PLAN FOR FARM POND
OWNER Q i f oC y
The purpose of this plan is to provide guidelines for carrying out the routine
maintenance work needed to keep this pond operating as planned. Routine main-
tenance is considered to be normal good care of the pond. Good maintenance
adds to beauty, usefullness, and permanence.
In addition severe storms that cause flow in-the vegetated spillway will likely
call for maintenance, such as, replacing and compacting soil in washes or gullies.,
reestablishment of vegetation, removal of debris and the like. When such work is
necessary, the Soil Conservation Service, if requested, will provide technical
assistance to help with the repair. This type of maintenance should be done as
soon as possible after damage is discovered.
The routine maintenance of this pond involves the following:
1. Maintenance of a vegetative cover on the dam and in the spillway:
Fes cm,e (Type of Vegetation) is being established on
these areas. Beginning in 7_<)1o3 (Year) and each year thereafter,
the dam and spillway should be fertilized with --?n C) pounds of
/O-ZO-Zo per acre to maintain a vigorous stand.
2. Removal of logs, brush, or other trash from the entrance of the pipe
spillway, the grass spillway, and the face of the dam: This should be
done after each rise in the pond surface that deposits such material.
Unless this material is removed, the pipe spillway is likely to become
clogged and the vegetation killed in the affected areas.
3. Control of weeds, brush, and trees in the grass spillway on the dam and
in the outlet channel for a short distance below the pipe outlet: This
may be done by mowing, spraying, or chopping, or-a combination of all
three. This will need to be done at least once each year and possibly
twice in years favorable to heavy growth-of vegetation. You may check
with the local Extension Agent or SCS office for the latest information
on spray material and the best time to-apply them.
4. If the dam and §pillway are to be grazed, be sure to remove all live-
stock when grass has been grazed down to a height of 4 inches. Also,
remove livestock when the dam and spillway are wet and soft. Severe
damage can be done by livestock at such times.
5. Protection of the Grass Spillway: The spillway can be severely damaged
by uncontrolled vehicular traffic. Trails or ruts made by such traffic
could become large gullies when outflow occurs in the spillway. If ruts
or trails appear to be forming, stop all traffic within the spillway
area.
