The site is an active mine and mining will continue at the site. Also, in conjunction with
this proposed large, Type 4 composting facility, a permit will be obtained to treat
petroleum contaminated soils.
j 2.0SITE SITING
The proposed Large Type 4, Davidson Compost Facility is located on two parcels of land
totaling 128 acres. The land is located about 1700 feet north of Hwy 64 on Cunningham
Road and about 4 miles south of Thomasville (See Figure 1 in Attachment A and
Property Deed in Attachment B). The land is within an active mine (Davidson Mine II,
Permit No. 29-06), and mining has been conducted since the 1960's by Cunningham
Brick. Land cleared and leveled by the mining activities will be used for the composting
areas. Approximately 2.1 acres of land will be used for the composting activities and 1.3
acres of land will be used for amendment storage.
Page2
Based on the USGS Quadrangle Map (Figure 1) and the USDA Soil Survey of Davidson
County (Figure 2), streams are present on the property. Past mining activities, especially
before the 1980's, had resulted in some stream disturbance in portions of the property.
Two culverts with road crossings have been installed in the past.
Per the USDA Soil Survey of Davidson County (Figure 2), Georgeville, Badin and
Oakboro soils are primarily present on the property. Georgeville and Badin soils have
seasonally high groundwater levels greater than 6 ft below groundsurface. Oakboro soils,
located along a perennial (Conrad Hill Branch) and intermittent streams, have a
seasonally high groundwater table of 1 to 2 feet and frequently floods.
Bedrock is present at relatively shallow depths and in accordance with the Geological
Map of North Carolina; the site is within the Carolina Slate Belt, Cid Formation. Bedrock
materials typically consist of Meta Mudstone and Meta Argillite with some inclusions of
Meta Sandstone and Meta Conglomerate. Based on visual observation of the mine
excavation a Meta Mudstone is predominate at the active mine areas.
The property containing two parcels is under Davidson County Jurisdiction. The property
is presently zoned Rural Agricultural District 3, and will be rezoned Heavy Industrial.
The confirmation letter from Davidson County will be provided once the property is
rezoned.
The facility is located outside of the 100-year flood plain (See Figure 3, Attachment A).
For the Type 4 composting facility, the compost areas are at least 174 ft from property
lines, 683 ft from the nearest residence, and at least 50 ft from an unnamed intermittent
stream and Conrad Hill Branch. Both streams are designated Class C. The facility is
located in the upland topography where no wetlands are located. No water supply wells
are present on the property. Public water supply is available to the surrounding areas.
Based on visually observations of the surrounding area, there are no water supply wells
within 800 ft. of the proposed compositing activities. The separately submitted maps
illustrate the various buffer distances discussed above.
Stormwater runoff is covered by the general permit NCG 020271. Also stormwater
runoff will be covered by the general composting permit NCG240000. All stormwater
will drain to erosion/stormwater structures approved through the mining program.
At the mined locations, shale is exposed at groundsurface. The composting will be
conducted on a 1.5 ft thick soil liner that has a coefficient of permeability slower than 1 x
10-7 cm/sec, a 6 inch thick protective layer will be placed over the soil liner.
Page3
I 3.0 Design Plan
Since the proposed facility is new, client or exact source of materials are only tentatively
known. No materials will be colleted from the general public. Feed stocks tentatively will
include pre and post consumer food waste from restaurants, biosolids from waste water
treatment plants, animal manure, lotions, perfume and tobacco waste. Amendments will
include sawdust, shredded yard waste, wood chips, and carbon black and alum, although
alum will primarily be used for the treatment of petroleum contaminated soils.
The facility will have the capacity to treat 14,670 cubic yards at any given time.
Treatment and curing on the composing pads will be approximately 60 days (2 months).
Yearly capacity is estimated at 14670 cubic yards/2 months x 12 months= 88,020 cubic
yards. On a weight basis, assuming a material density of 1.15 tons/cubic yard, annual
capacity is estimated at 101,223 tons. Estimation of incoming materials on an average
monthly basis is difficult to predicate at this time, without knowing the exact source and
client needs.
Prior to acceptance of biosolids, alum, lotions, perfume, and carbon black, analytical
testing will be conducted on the material annually received from each source. Analytical
testing will be per Table 1 in Attachment A.
Feed stock and amendments will be blended to achieve a Carbon to Nitrogen (C:N) ration
of 20 to 30. A Carbon Hydrogen Nitrogen (CHN) analyzer or similar analytical methods
will be used to determine the C:N ratio for each material. Prior to blending, the moisture
content and dry density of each material will be determined. The blending proposition by
weight will be based on the following equation:
R= 01 (C1x(lOO-M1) + 02 (C2x(lOO-M2) + 03 (C3x(lOO-M3) + .. .
Qi (N1x(lOO-M1) + Q2 (N2x(lOO-M2) + Q3 (N3x(lOO-M3) + .. .
In which: R=C/N ratio of compost mixture Qn = mass of material n ("as is", or "wet
weight") Cn=carbon (%) or material n, Nn= nitrogen(%) or material n, and Mn= moisture
content(%) of material n.
Prior to full production activities, a pilot test will be conducted to verify appropriate
compost feasibility for each new source of material.
Figure 4 in Attachment A provides a process flow diagram for the entire facility. The
trucks transporting the material to the facility are weighted. The trucks then dump the
alum, biosolids, lotions and perfume directly on the compost pads. Carbon black will be
kept in the shipping containers (barrels and super sacks) until the blending time. Saw
dust and wood chips may also be dumped directly on the compost pad, but may also be
stored separately. Yard waste will be stored separately until about 6000 cubic yards is
accumulated and then the material will be ground to smaller sizes. An independent
Page4
contractor will be hired to grind the yard waste once sufficient quantities are
accumulated.
As shown on the separately submitted site plan the compost and storage areas will be
graded to promote gravity drainage to sediment/stormwater basins. With the exception of
the yard waste, sawdust and wood chips, all other feed stocks and amendments will be
stored under a tarp to prevent direct rain contact. The composting pads will have broad
swales between each pad which can convey the 25-year rain event. In addition to the
existing general mine stormwater permit NCG020271, the facility will have a general
composting stormwater permit NCG240000.
The haul roads leading to the various site locations are also used for mine access. These
roads are surfaced with a combination of brick and No. 57 stone to provide all-weather
access. To provide all-weather access around the storage and composting areas, the shale
excavated at the mine will be used to cover the ground. The shale will also be used as a
protective layer for the soil liner at the compost pads.
The majority of amendments and feed stock will be covered by a tarp and will prevent
wind loss of material. Haul roads and any exposed ground areas will be wetted as needed
to minimize fugitive dusting.
Odors will primarily be controlled by maintaining the compost in aerobic conditions.
Odors will also be controlled by blanketing the compost pile with previously composted
material or with sawdust and wood chips.
Maintaining a temperature of less than 190° F will be the primary means of preventing
fires. Smoldering areas of the compost pile, and the stored sawdust and mulch are
indicative of the beginning of a fire. Smoldering areas will be uncovered and dosed with
water. The sediment/stormwater ponds will be used as the source of water. The fire
department will be notified for additional help in extinguishing fires
! 4.0 OPERATION PLAN
Attachment C contains the Operation Plan.
5.0 STORMWATER DISCHARGE AND SEDIMENT AND EROSION CONTROL
PLAN
The facility is presently permitted as a mine. The mine permit is in the process of being
modified for inclusion of the composting activities. A stormwater permit will also be
obtained for the composting activities.

I 2.0 Material Acceptance
Material acceptance is based on the facility type or generator of material; chemical/metals
in the material and material characteristics that determine hazardous/non-hazardous
material; and compatibility of the material for composting.
Being familiar with the type of facility or generator will provide insight as to whether
materials should be accepted from such facility. Interviews with the generator, review of
MSDS information, and an understanding of the generator's process will help in
determining if the waste is non-hazardous and compatible for composting. This
screening process will also help in determining additional analytical testing requirements.
Amendments will generally not require testing except for carbon black and alum sludge.
Feed stocks that can not be verified as non-hazardous or are biosolids from waste water
treatment plants will require the following TCLP testing:

In addition to the Hazardous material screening, all feed stocks and amendments except
wood and yard waste will be tested for the following metals. The noted metal limits are
general based on Table 3 of 40 CPR 503.18. The actual results from the materials will be
used to estimate final limits of the blended material. The estimated final metals

Moisture content: 50% to 60%
Ph: 6 to 8
Once the blended compost formula has been developed, a pilot scale evaluation may be
warranted. The pilot scale composting activity will aid in determining aerobic
composting rate, test actual blending proportions, verify suitable fee air space or voids in
the blended material.
I 3.0 STANDARD OPERATING PROCEEDURES
Both the non-hazardous material and the biosolids are transported by truck to the facility
and weighed. No material shall be unloaded until proper documentation is present. All
loads shall be tarped with contents not exceeding six inches below the top of the trailer
edge. The office manager is responsible for preparing and providing waste manifests and
Chain of Custody documentations for the drivers.
Page 5
The trucks then unload the material directly on the appropriate pad. For the biosolids an
initial layer of sawdust or mulch is placed on the pad before placement of the biosolids.
Since this is a mine, truck drives are not allowed to leave their trucks.
Bulking agents such as sawdust are added to the biosolids immediately once placed on
the pad. The blended material is shaped with an end load in elongated 20 foot high piles
and covered with a weighted tarp. Temperature of the material is maintained between 131
to 170 degrees Farenheight for at least 21 days. The material is aerated at least twice
during this time period, but aeration can be more frequent depending on the temperature
of the material. The aeration is accomplished with a skat, endloader or power screen. All
unloading and aeration of the material is conducted during clear weather conditions. (No
activities are conducted during precipitation or eminent precipitation.) The compost
material will cure for about 40 days.
After vector pathogen reduction is achieve by fecal coliform reduction of less than 100
CFU (average), the material is load on a truck and transported to the petroleum and non-
hazardous contaminated material stockpile and blended at a 1: 10 ratio (biosolids:
contaminated soils), sold in bulk or used to reclaim the inactive mine areas.
j 4.0 COMPOST PAD SPECIFICATIONS
At least 1.5 feet of well compacted clay soil with a coefficient of permeability (k) slower
than lx107 cm/sec is provided at the compost pads. A six inch protective soil layer will
be place over the liner. Direct precipitation contact is prevented by placement of a tarp
over the material being treated. The tarp is provided over the material generally for most
of the time. The material is only uncovered during aeration and bending activities or
when loading and unloading the material. Stormwater drainage is provided by diversion
ditches upslope and in between the compost pads. The water is diverted to a basin prior to
discharging from the site. The diversion ditches can divert the runoff from a 25-year rain
event.
The compost pad shall be constructed in three (3) six inch compacted lifts. For each lift,
a permeability test and density test will be conducted every 330 ft. of pad. The soil shall
be compacted to at least 95 % of standard Proctor maximum dry density (ASTM D-698).
The permeability of the soil shall be determined by ASTM D5084.
j 5.0 COMPOST MONITORING
Dailey temperature of the compost material will be conducted every 100 lineal feet of the
compost. For biosolids, once the material has been treated, fecal coliform testing shall be
conducted every 300 lineal feet of the compost windrow.

! 6.0 INSPECTION
Daily Observations also include the following:
1. Equipment Leaks
2. 250 gallon Diesel AST Leaks and spillage
3. Debris and litter
4. Temperature of sawdust and mulch piles
5. Loss or erosion of amendments stored on the site
One weekly, or after a runoff producing rain event, and general facility area is observed.
j 7.0 RECORD KEEPING
Each new compost pile is assigned a number for tracking purposes. For the biosolids, the
following is recorded.
1. Source of biosolids
2. Percent solids in the biosolids
3. Calculated dry tons ofbiosolids
4. Cubic yards of amendments added
5. Daily Temperature readings and Length of Treatment
6. Date material is blended with contaminated soil
7. Date material is on-site land applied
8. Weather conditions and date when biosolids are transported to facility,
aerated, blended with contaminated soil, and on-site land applied.
Also, records are maintained for all surface water and monitoring well sampling. All
records are maintained on file for a period of at least 5 years.
j 8.0 SPILL CONTINGENCY
Anticipated spills can include the following:
1. Biosolids, Petroleum Contaminated Soil, and amendments released from
trucks
2. Fluids released from truck engines and diesel tanks
3. Leachate from biosolids compost piles
4. Spills and releases from the 250 gallon diesel AST
I I-
Page7
Truck releases can be minimized by ensuring the driver knows where to drive on the site
by providing signs and employees directing the driver to the proper locations. The truck
tailgate should also be checked to ensure adequate seal and no loss of material is
occurring. Trucks should also be checked for any hydraulic fluid, oil, and petroleum leaks
from the engine and tank when it enters the site. On-site equipment should be checked at
the beginning of each day for any ground staining caused by engine and truck leaks.
Leachate from biosolid compost piles is minimized by placement of a layer of sawdust or
mulch on the compost pad before unloading the biosolids. Blending the biosolids with
sawdust and mulch also greatly reduces the likelihood of leachate from occurring.
Damaged Tarps should be replaced immediately.
A barrier is provided around the 250 gallon AST to prevent accidental collision with the
equipment and private vehicles. During equipment filling and during resupply filling of
the tank, the employee is to be present at all times. Integrity of the tanks should be
checked on a daily basis.
Biosolids and contaminated soil loss from the truck can be hand-shoveled back into the
truck or into the endloader bucket and placed into the appropriate compost pile. Large
releases will need to be removed with the endloader.
j 9.0 FIRE PREVENTION
Fires can occasionally occur in sawdust, mulch, and biosolid piles if the temperature
inside the pile is allowed to reach 180° F. Smoldering areas of the pile are indicative of
the beginning of a fire. The pile should be broken up and covered with soil to prevent a
fire. Should a fire occur, call 911 for the fire department.
j 10.0 ODOR CONTROL
Biosolid composting can produce odors especially during hot weather conditions.
Whenever possible, the biosolid pile should be aerated when the winds are in an easterly
and northerly direction away from any residential dwellings for more than Yz mile.
Keeping the material covered will help but a thin layer of sawdust or mulch covering the
pile can also help reduce odors.
