Dear Mr. Kormanik
Enclosed please find two copies of the revised Erosion Control Plan per your review comments in the letter
dated September 2, 2014The revisions are addressed as follows:
1. The outflow from the dual 15 inch diameter culverts are both directed into the proposed skimmer
sediment basin. We have adjusted the grading at the pond to show this as well as indicated a note
on the plans to ensure this will occur.
2. The southwest comer of the site within the gravel operations area currently drains into the proposed
skimmer sediment basin. That is our intent. To ensure this occurs we have extended the silt fence
along the southern property line and provided a construction note indicating the intent.
3. We have added the Table of Permit Stabilization Requirements as requested.
4. Per your request, a copy of this Erosion Control and Stormwater Pollution Plan & Application
package has been forwarded to Bradley Bennett with NCDENR regarding our current NCGO1000
General Construction Stormwater Permitting.
If you should have any questions or need any additional information during you review please contact me.

Introduction
Southern Shavings Company, Inc. in an effort to comply with the State of North
Carolina Department of Environment and Natural Resources Division of Water Quality
standards and regulations has engaged LandWorks Engineering to prepare all
necessary erosion and stormwater control plans, calculations and applications on its
behalf for the Fallston Production Facility which was opened in December of 2008.
Currently Southern Shavings operates under NCNPDES NCG210000 General
Stormwater Permit issued for the Site in 2010.
Project Description
On July 29, 2014 the North Carolina Department of Environment and Natural Resources
(NCDENR) Land Quality Section visited the Southern Shavings Company an existing a
shavings production facility located at 317 Jim Cline Road in Fallston, NC. At this
facility, pine trees or cedar trees as raw material are manufactured into shavings, taken
off site to Cherryville, NC to be packaged into bales and sold as bedding materials for
horses and other animals.
Trees are the only raw material stored at the site. The logs come into the facility
on log trucks are weighed and are off loaded with a knuckle boom truck into one of three
timber storage and staging areas. During NCDENR's visit the areas around the tree
storage area what is referred to as the "operations area"was observed to be disturbed
and muddy due to the wet weather and the and the heavy equipment used to transport
the logs into the trough for processing. During the wet season the high traffic operations
area becomes contaminated with soil and appears very muddy. The remainder of the
site approximately 7.8 acres is undeveloped and consists of wooded and field grass
areas.
Ryan Kormanik with NCDENR inspected the site and determined that corrective action
was necessary by the facilities owner to control stormwater runoff and sediment from
leaving the site for protection of the downstream watershed. The described corrective
action needed includes:
1. Submit an adequate Erosion and Sedimentation Control Plan for approval,
covering all areas disturbed or to be disturbed.
2. Install Erosion and Sediment Control devices sufficient to retain sediment on the
tract.
To comply with the NCDENR report Landworks has designed a skimmer
sediment basin below the disturbed area on site that will collect and treat the stormwater
runoff flowing on to and through the site. Treatment will consist of capturing, storing and
releasing the stormwater over two -five days allowing any soil/silt particles to settle out
prior to release. The treatment ponds have been designed in accordance with
Stormwater Best Management Practices, the NPDES General Permit NCG210000
and the NC Erosion and Sedimentation Control Planning and Design Manual.
Site Characteristics & Soils Information
The site consists of two parcels totaling 11.81 acres. The site falls gently from
right to left over its 450 ft. frontage and front to back over its 1040 ft depth. On the rear
of the property there is an unnamed tributary to Magness Creek. A 30 foot undisturbed
buffer exists of the unnamed creek tributary as it travels through the property. Site
Soils consist of predominantly Cecil Sandy Clay Loam (CaB2) 2-8% slopes, transitioning
to Pacolet Sandy Clay Loam (PaC2) 8-15% slopes and finally Chewacla Loam (ChA) 2-
8% slopes as you reach the creek.
The site has a gravel entrance driveway and a gravel operations/unloading and
employee parking area around the manufacturing facility. During the wet season the
high traffic gravel area in the operations area becomes contaminated with soil and
appears muddy. The site consists of two drainage areas one to the northwest and one
to the southeast. Both extend off the property to the north and encompass a portion of a
paved parking lot and building serving Alive Apparel Inc. The northwest drainage area
is 3.52 acres and has a 29.8% impervious area. The southeast drainage area is 3.42
acres and 16.4% impervious. The stormwater outfalls on the site have been evaluated
for the presence of non stormwater discharges and there is no evidence of any non-
stormwater discharges from the site.
With the sites exposure being limited to the short term storage of harvested logs,
the primary pollutant anticipated within the stormwater is sediment transported from the
gravel/mud parking area or any disturbed areas on the site. Landworks has designed a
stormwater/sediment ponds to capture, treat and slowly release the Stormwater runoff
from the site.
Construction of the stormwater treatment facilities and erosion control measures
on the site shall be in accordance with North Carolina Department of Environment and
Natural Resources (NCDENR) BMP and erosion control standards and specifications.
Stormwater Runoff and Drainage
The site has a 8.74 acre drainage area toward the south west corner of the
property before discharge into an unnamed tributary to Magness Creek a INS IV
watershed. Stormwater runoff travels in a sheet flow condition from a parking lot and
roof north of the site and then overland flow through a grass field onto the site.
A new intercept channel was designed to collect and convey the undisturbed
drainage area above the site (3.24 acres) and safely discharge it before it becomes
contaminated with sediment traveling through the operational area on -site.
The storm drain piping shall be High Density Polyethylene (HDPE) meeting
ASHTO specifications M 294. All storm drainage construction means and methods shall
be constructed in accordance with North Carolina Department of Transportation
(NCDOT) installation and Material specifications. Storm drain piping was installed in
accordance with the manufacturers written installation instructions.
TR55 was used to calculate the storm water run-off. A Composite CN-value for
each drainage basin area was calculated as 80 off site and 76 on the main site. The
storm drainage system was designed to safely collect and convey the 25 year, 24 hr.
storm event with a 10 minute time of concentration. A rainfall depth of 528 in/hr
corresponds to this storm event, according to National Oceanic and Atmospheric
Administration (NOAA). Storm drainage and ditches on the site were designed to collect
& convey a 25-year storm runoff event safely through the site. This additional storm
capacity will provide improved safety by adding redundancy should a large storm event
occur at the site. All culvert collection areas will be equipped with inlet protection and all
culvert discharge locations will be outfitted with rip rap plunge pool energy dissipaters
which assures that the water will be properly treated prior to entering the piping. The
plunge pools are rip -rap stones in a bowl shape which decrease the outlet velocity by
capturing the storm water in a collection area prior to allowing the storm water to sheet
flow along its natural course.
Note: Permanent Stormwater Treatment facilities shall be inspected on a semi-annual
schedule. Any repairs or deficiencies shall be corrected immediately. A record log shall be
maintained on the site by the owner and will record any deficiencies and the corrective
measures taken.

Introduction
Southern Shavings Company, Inc. in an effort to comply with the State of North
Carolina Department of Environment and Natural Resources Division of Water Quality
standards and regulations has engaged LandWorks Engineering to prepare all
necessary stormwater control plans, calculations and applications on its behalf for the
Fallston Production Facility which was opened in December of 2008 for the collection,
treatment and discharge of stormwater to the surface waters of North Carolina in
compliance with NPDES General Permit NCG210000
Project Description
Southern Shavings Company has constructed a shavings production facility on 317 Jim
Cline Road in Fallston, NC. At this facility, pine trees or cedar trees as raw material are
manufactured into shavings, taken off site to Cherryville, NC to be packaged into bales
and sold as bedding materials for horses and other animals. Trees are the only raw
material stored at the site. The logs come into the facility on log trucks are weighed and
are off loaded with a knuckle boom truck into one of three timber storage and staging
areas. There are two locations for pine logs and one location for cedar logs, each can
hold approximately 60 tons of raw material. The stored material is used depending upon
the demands of the Cherryville processing/packaging plant. The stockpiles are
constantly being replenished with new stock as the oldest logs are manufactured into
shavings. Typically the stock rotates every seven days.
The manufacturing of shavings takes place as timber logs are fed into a trough and cut
to an 8 ft. length. The logs are then dropped into a set of boxes that move back and forth
over four (4) shavers that make shavings from the logs. The shavings are carried by a
series of conveyor belts to a drier where the shavings and any saw dust resulting from
the shavings process are air dried. From there the air dried shavings and saw dust are
sent to a shaker table where the saw dust is separated from the shavings. The saw dust
is sent back to the burner as fuel for the air drying process and the wood shavings are
blown into storage trailers on the site. The full storage trailers are hauled to the
Cherryville Facility for processing, packaging and delivery to customers.
Southern Shavings Company was first alerted to the need for an Industrial Stormwater
permit by Dee Browder from NCDENR Mooresville Office in the May of 2010. It is
important to note that the facility has only raw product (trees) stored outside. No finished
product is stored outside and there is no other significant exposure within the site
boundaries.
To comply with the NPDES Stormwater regulations we are proposing construction of two
water quality treatment areas that will collect and treat the stormwater runoff flowing
through the site from the first inch of rainfall. Treatment will consist of capturing, storing
and releasing the stormwater over two -five days allowing any soil/silt particles to settle
out prior to release. The treatment ponds have been designed in accordance with
Stormwater Best Management Practices.
Site Characteristics S Soils Information
The site consists of two parcels totaling 11.81 acres. The site falls gently from
right to left over its 450 ft. frontage and front to back over its 1040 ft depth. On the rear
of the property there is an unnamed tributary to Magness Creek. A 30 foot undisturbed
buffer exists of the unnamed creek tributary as it travels through the property. Site
Soils consist of predominantly Cecil Sandy Clay Loam (CaB2) 2-8% slopes, transitioning
to Pacolet Sandy Clay Loam (PaC2) 8-15% slopes and finally Chewacla Loam (ChA) 2-
8% slopes as you reach the creek.
The site has a gravel entrance driveway and a gravel operations/unloading and
employee parking area around the manufacturing facility. Please note: During the wet
season the high traffic gravel area in the operations area becomes contaminated with
soil and appears muddy. The remainder of the site approximately 8.2 acres is
undeveloped and consists of undisturbed woods and field grass areas.
The site consists of two drainage areas one to the northwest and one to the
southeast. Both extend off the property to the north and encompass a portion of a paved
parking lot and building serving Alive Apparel Inc. The northwest drainage area is 3.52
acres and has a 29.8% impervious area. The southeast drainage area is 3.42 acres and
16.4% impervious. The stormwater outfalls on the site have been evaluated for the
presence of non stormwater discharges and there is no evidence of any non-stormwater
discharges from the site.
With the sites exposure being limited to the short term storage of harvested logs,
the primary pollutant anticipated within the stormwater is sediment transported from the
gravel/mud parking area or any disturbed areas on the site. Landworks has designed
two stormwater/sediment ponds (one serving each drainage area) to capture treat and
slowly release the Stormwater runoff from the site.
Construction of the stormwater treatment facilities and erosion control measures
on the site shall be in accordance with North Carolina Department of Environment and
Natural Resources (NCDENR) BMP and erosion control standards and specifications.
Stormwater Runoff and Drainage
The site has two drainage areas both draining toward the south west corner of
the property before discharge into an unnamed tributary to Magness Creek a WS IV
watershed. Stormwater runoff travels in a sheet flow condition from a parking lot and
roof north of the site and then overland flow through a grass field onto the site.
The storm drain piping shall be High Density Polyethylene (HDPE) meeting
ASHTO specifications M 294. All storm drainage construction means and methods shall
be constructed in accordance with North Carolina Department of Transportation
(NCDOT) installation and Material specifications. Storm drain piping was installed in
accordance with the manufacturers written installation instructions.
TR55 was used to calculate the storm water run-off. A Composite CN-value for
each drainage basin was calculated as 76. With a ten (10) minute time of concentration.
The storm drainage system was designed to safely collect and convey the 25 year, 24
hr. storm event with a 10 minute time of concentration. A rainfall intensity of 6.0 in/hr
corresponds to this storm event, according to Natural Resources Conservation Service
(NRCS). Storm drainage and ditches on the site were designed to collect & convey a
25-year (NRCS) storm runoff event safely through the site. This additional storm
capacity will provide improved safety by adding redundancy should a large storm event
occur at the site. All culvert collection areas will be equipped with inlet protection and all
culvert discharge locations will be outfitted with rip rap plunge pool energy dissipaters
which assures that the water will be properly treated prior to entering the piping. The
plunge pools are rip -rap stones in a bowl shape which decrease the outlet velocity by
capturing the storm water in a collection area prior to allowing the storm water to sheet
flow along its natural course.
Note: Stormwater Treatment facilities shall be inspected on a semi-annual schedule. Any
repairs or deficiencies shall be corrected immediately. A record log shall be maintained on
the site by the owner and will record any deficiencies and the corrective measures taken.

These volumes are achieved when the water depth in each pond = 1 ft.
The stormwater in the pond will slowly infiltrate into the Cecil Sandy Clay Loam soil.
However, in accordance with BMP Design requirements, we want to ensure that the pond drains
down within 2-5 days.
So using the falling head Eqn. we will design an orifice to drawdown the storage of the ponds in
2 days.

Cut a 1-1/4 inch diameter hole at the base of the pond riser. Install a 12" sq. x patio block
directly adjacent to the hole to keep vegetation from blocking the orifice
Surround the riser with a ring of #57 washed stone to filter out suspended sediment from the
stormwater prior to discharge.
The runoff from the first inch of rainfall is safely captured and treated prior to release.
Emergency Spillway Design (safely pass the runoff from the 25 year event)
Both ponds have similar inflow rates and volumes so to keep things simple both ponds will use a
similar design incorporating an 18" dia riser pipe with an 18" dia outlet pipe.
For the 25 year event at each pond
Weir Eqn: Q=CIhT1.5
1=3.1416xpipe dia. =3.14x 1.5=4.71 ft.
16.61=3x4.71 xhT1.5
Sloving for h
h = (16.61/14.13)T0.666
h = 1.0 ft over riser during a 25 year storm event
similarly h = 0.92 ft. during the 10 year event.
All stormwater runoff from the 25 year event safely passes over the riser and through the
outlet pipe in the pond, while providing 1 foot of freeboard around the pond perimeter.
Anti -Flotation / Bouvanev Calculations
Diameter of Riser = 18 inches
Weight of Riser = 90#
Weight of atrium dome grate = 20#
Weight of water = 62.4#/cubic foot
Height of water displaced = 1 foot.
Weight of saturated soil = 120 4/cubic foot
Weight gravel = 120 #/cubic foot
Upward Force T
weight of displaced water =n X diameter X height of riser X weight of water
3.1416 x 1.5 ft.x 1 ft. x 62.4 #/cf = 294.05 #
Downward Force j
Weight of riser pipe and trash rack +weight of washed stone in invert extension (n X

Factor of safety against uplift = 392.74/294.05 = 133 therefore OK
Qualitative Monitoring Requirements
With the sites exposure being limited to the short term storage of harvested logs, the
primary pollutant anticipated within the stormwater is sediment transported from the
any disturbed areas on the site. Both bio-retention ponds outfalls will require
Qualitative Monitoring. Qualitative monitoring which requires a visual
inspection of each stormwater outfall regardless of representative outfall status
and shall be performed as specified below in Table 4. Qualitative monitoring is
for the purpose of evaluating the effectiveness of the Stormwater Pollution
Prevention Plan (SPPP) and assessing new sources of stormwater pollution. No
analytical tests are required. Qualitative monitoring of stormwater outfalls must
be performed during a representative storm event.

I Monitoring Location: Qualitative monitoring shall be performed at each
stormwater discharge outfall (SDO) regardless of representative outfall status.
If the permittee's qualitative monitoring indicates either that existing stormwater
BMPs are ineffective, or that significant stormwater contamination is present, the
permittee shall investigate potential causes, evaluate the feasibility of corrective
actions, and implement those corrective actions appropriate. A written record of the
permittee's investigation, evaluation, and response actions shall be kept in the
Stormwater Pollution Prevention Plan.
Qualitative monitoring is for the purposes of evaluating the effectiveness of the
stormwater Pollution Prevention Plan (SPPP), assessing new sources of stormwater
pollution, and prompting the permittee's response actions to pollution. If the
permittee repeatedly fails to respond effectively to correct problems identified by
qualitative monitoring, or if the discharge causes or contributes to a water quality
standard violation, DWQ may:
• require that the permittee revise, increase, or decrease the monitoring
frequency for the remainder of the permit;
• rescind coverage under the General Permit, and require that the permittee
apply for an individual stormwater discharge permit;
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures; or
• require that the permittee implement site modifications to qualify for the No
Exposure Exclusion.
Qualitative monitoring will be performed twice per year, in accordance with the
schedule in Table 2. A minimum of 60 days must separate Period 1 and Period
2 monitoring dates, unless monthly sampling has been instituted under a Tier Two
response as part of other analytical
monitoring requirements in this permit.
Reporting Requirements
Discharge Monitoring Reports
Samples analyzed in accordance with the terms of this permit shall be
submitted to the Division on Discharge Monitoring Report forms
provided by the Director. Submittals shall be delivered to the Division
no later than 30 days from the date the facility receives the sampling
results from the laboratory.
When no discharge has occurred from the facility during the report
period, the permittee is required.to submit a discharge monitoring
report, within 30 days of the end of the six-month sampling period,
giving all required information and indicating "NO FLOW" as per
NCAC T15A 0213 .0506.
The permittee shall record the required qualitative monitoring
observations on the SDO Qualitative Monitoring Report form provided
by the Division, and shall retain the completed forms on site. Visual
monitoring results should not be submitted to the Division, except
upon DWQ's specific requirement to do so.
