14'
A temporary permeable barrier erected on small disturbed areas to capture sediment from sheet flow. Itb made of
filter fabric buried at the bottom, stretched and supported by steel posts.
Planning:Silt fence will be installed along the perimeter of pond access road when crossing an existing blue-line-stream
field ditch. Narrow width of fenced area will allow only shallow pools to form behind fence while promoting deposition
ofsedimentandpreventingsedimentat|Pnintoadiacentvvet|ands. EndsoffenceVvi|| becudeduphil| in ^]vpatternt$
prevent end flow. Stabilized outlets will be provided to protect the fence system and release storm flow that exceeds
the design.
Design considerations:Silt fence will be constructed of extra-strength synthetic filter fabric. Height of fence will not
exceed 2 feet above natural ground level, and will be constructed from a continuous roll to minimize joints. All joints
will be fastened at a support post with 4 feet minimum of overlap. Extra-strength filter fabric will be fastened to road
side of steel posts(installed 2 feet deep)every 6 feet(every 8 feet if using standard strength filter fabric with wire mesh
backing)and fastened with wire ties. Trench will be excavated along inside of fence approximately 4 inches wide by 8
inches deep,into which 12 inches of fabric will be placed along the bottom and side of the trench. Trench will be
backfi||ed and compacted.
Maintenance: Inspect sediment fence every week and after each rainfall. Make any required repairs immediately.
Replace any collapsed,damaged,or decomposed fence promptly. Remove all fencing materials and unstable sediment
deposits and bring the area to grade and stabilize it after the contributing drainage area has been properly stabilized.

Construction Road Stabilization Details
Practice Standards and Specifications 6.80
Alvin Road Mine
Grimesland,NC
Pitt County
Definition: The stabilization of temporary construction access routes,on-site
vehicle transportation routes,and construction parking areas.
Purpose: To control erosion on temporary construction routes into Eure Sand
Mine.
Planning Considerations: Improperly planned and maintained construction roads can become a
continual erosion problem.Situate construction roads to reduce erosion
potential.When practical,install permanent paved roads and parking
areas and use them for construction traffic early during the construction
operation to minimize site disruption.
Design Criteria: Road Grade—A maximum grade of 10%to 12%is recommended,
although grades up to 15%are possible for short distances.
Road Width-12 feet minimum for one-way traffic
—20 feet minimum for two-way traffic
Side Slope of Road Embankment-2:1 or flatter
Ditch Capacity—Roadside ditch and culvert capacities-10-year peak
runoff.
Stone Surface—Use a 6-inch course of"ABC'or"base course"or larger
as specified in NC Department of Transportation Standard Specifications
for Roads and Structures,as needed.
Construction Specifications: 1. Clear roadbed and parking areas of all vegetation, roots,and other
objectionable material.
2. Ensure that road construction follows the natural contours of the
terrain if it is possible.
3. Locate processing areas on naturally flat areas, if they are available.
Keep grades sufficient for drainage, but generally not more than 2-3%.
4. Provide surface drainage,and divert excess runoff to stable areas by
using water bars or turnouts.

S. Keep cuts and fills at 2:1 or flatter for safety and stability and to
facilitate establishment of vegetation and maintenance.
6. Spread a 6-inch course of"ABC' crushed stone evenly over the full
width of the road and smooth to avoid depressions.
7. Where seepage areas or seasonally wet areas must be crossed,
install subsurface drains or geo-textile fabric cloth before placing the
crushed stone.
S. Vegetate all roadside ditches,cuts,fills,and other disturbed areas or
otherwise appropriately stabilize as soon as grading is complete.
9. Provide appropriate sediment control measures to prevent off-site
sedimentation.
Maintenance: Inspect construction roads and parking areas periodically for condition
of surface.Top-dress with new gravel as needed. Check road ditches
and other seeded areas for erosion and sedimentation after runoff-
producing rains. Maintain all vegetation in a healthy,vigorous condition.
Sediment-producing areas should be treated immediately.

Berm Construction Details
Alvin Road Mine
Grimesland, INC
Pitt County
Narrow-based berm
The narrow-based berm is the most common berm having a top of 2 feet(0.6 m)and side slopes of two
horizontal: 1 vertical.This berm is the most economical to build as it requires the least material.The
steep side slopes of this type of berm eliminate the possibility of working on it with farm machinery.

NEW BERM EXISTING
GRADE
Berm Construction
The berm construction comprises of the scraping back of the topsoil from the area where the berm and
storage basin is to be built.A subsoil material,free of stones, rubble, stumps etc. and with at least 10%
clay should be used to construct the berm.The material for the berm may be obtained from the area
behind or in front of the berm location or moved from a borrow pit located elsewhere on the farm.An
earth mover will be required to move material from a pit located a distance away while a bulldozer
would be used if material is located in the berm area.
The berm material is to be placed in layers and compacted as each layer is added. After the berm has a
final shape the sides of the berm should also be compacted.
Emergency Overflow
To provide for larger-than designed peak flows,an overflow system is used, namely:
• "The level-top vegetated berm crest"which provides for very flat berm top so that the water will
overflow along the berm length in a thin layer so as not to create erosion problems.

Purpose: To reduce erosion in overflow drainage outlet during major rainstorms by reducing velocity of flow, and
provide sediment control.
Siting: To be placed at lower end of sand mine disturbed area perimeter berm (8ft x 3ft sand berm).
Aggregate Size:NC DOT Class B stone lined with NC DOT#5 or#57 stone on upper side.
Construction Specifications: Keep center stone section 6 inches below top of sand berm. Place sediment control stone
minimum 1ft thick on upstream side of berm at weir. Provide 9ft long stone apron on lower side of berm to flush with
surrounding grade.
Maintenance: Inspect check dams weekly and after significant rainfall and repair immediately if needed. Clean out
limbs, sediment and other debris that could clog the weir. Add stones to check dam to maintain correct height.
Maintain vegetative ground cover on berm, repair berm erosion as needed.

PROFILE
CHECK DAM DETAIL
A rock embankment located to capture sediment in a naturally formed drainage feature. The purpose of a rock dam is
to trap sediment on the construction site, and prevent off-site sedimentation in streams, lakes and drainageways.
Planning: Used where it is desirable to have the top of the structure serve as the overflow outlet. A long weir crest is
designed to keep flow depth shallow and discharge velocity low. Inside face of the dam will be covered with gravel to
reduce rate of seepage so that a sediment pool will form during runoff, draining slowly through the dam.
Design considerations:
• Maximum height—weir elevation 6 feet above ditch grade.
• Embankment—top width 2 feet minimum, side slopes maximum 2:1 upstream slope, maximum 3:1 downstream
slope. Rock abutments will extend to an elevation at least 1 foot above the spillway.
• Outlet protection—rock apron minimum 1.5 feet thick will extend downstream from the toe of the dam a
distance equal to the height of the dam to prevent channel erosion.
• Rock fill—rock will be well graded erosion resistant stone with a minimum dsosize of 12 inches, Class II
downstream layer of riprap and Class I upstream layer of riprap.
Maintenance: Check sediment basin after each rainfall, remove sediment when sediment accumulates to Y2 the height
of the dam. Check structure for erosion or rock displacement weekly or after each significant (1/2 inch or greater)
rainstorm and repair immediately.

DESCRIPTION
A structure in a water management system that conveys water, controls the direction or rate of flow, maintains a desired
water surface elevation or measures water. Water height control structure is standard structure used by agricultural and
horticultural farms in North Carolina to raise or lower water height in ditches and ponds per need (NRCS). Water height
control structure to be installed in the south berm of the sedimentation pond at the Alvin Road Mine. Overflow to be
directed down stabilized ditch to nearby blue-line stream, eventual outflow to Tar River.

PURPOSE
To convey water from one elevation to a lower elevation within, to, or from a water conveyance system, such as a ditch,
channel, canal, or pipeline designed to operate under open channel conditions. Typical structures: drops, chutes,
turnouts, surface water inlets, head gates, pump boxes, and stilling basins(NRCS). This water management system will
be used to maintain a maximum water surface elevation in the sedimentation pond at the Alvin Road Mine, Alvin Road,
Grimesland, NC. Sedimentation pond is a part of the dewatering management system of the Alvin Road Mine, used to
remove settleable matter and turbidity from mine dewatering wastewater.
CONSTRUCTION
Structure consists of 26' x 3' horizontal galvanized steel culvert running under the sedimentation pond berm. A vertical 6'
half pipe 52"x 30" is attached on the north end of the culvert with stacked flash boards allowing adjustable height of the
water level in the sedimentation pond. Water flows over the flash boards and into the discharge pipe and down the rip-rap
stabilized ditch.
Overflow ditch is lined with riprap for 20 feet down its length. Existing slopes adjacent to the culvert are heavily grassed
with natural grass and weeds with no erosion present.
MAINTENANCE
Structures will be checked and necessary maintenance, including removal of debris, shall be performed after major
storms and at least semi-annually.

Riprap lined apron located at end of mine dewatering overflow pipes(3)to prevent scour and
undermining in existing ditch,and to absorb the impact of the water flow and reduce the velocity to
non-erosive levels, before flow reaches wetlands.
Riprap Apron Size: Overflow pipe discharges directly into well-defined channel. The apron will extend
across the channel bottom and up the channel banks to the top of the bank. Length of apron will be 20-
feet downstream to maintain velocity control of maximum 2.0 feet per second.
Grade: Apron will have zero grade and no overfill at end of apron.
Alignment: Apron will be straight throughout entire length if possible. If curve is necessary to align the
apron with the receiving channel,the curve will be located in the upstream section of the riprap.
Materials: Riprap will consist of a well graded mixture of NCDOT Class A(2"to 6")stone or slag.
Thickness: Minimum thickness of riprap will be 1.5 times the maximum stone diameter.

Filter: Operator plans to install a layer of heavy duty silt fence filter cloth between the riprap and the
underlying soil to prevent soil movement into or through the riprap. Filter cloth will extend to the top of
both channel banks,and edges will overlap 12 inches. Upstream end will be buried 12 inches and
downstream end will be buried if necessary.
Maintenance: inspect riprap outlet structures weekly and after significant rainfall events to see if any
erosion around or below the riprap has taken place,or if stones have become dislodged. Repair all
damage immediately. Maintain all vegetation adjacent to the channel in healthy condition to prevent
scour or erosion during out-of-bank flow. Control weeds and brush growing in the riprap by cutting.
