Design Capacity
The specific compost process that is to be used is the windrow method. An initial pile will be constructed
with a triangular cross section utilizing one day's dewatered septage and/or grease production.The
windrows must be maintained at a temperature of 131 degrees F and will be turned a minimum of 5 times
in 15 days.
The windrows will be 8 feet high, 50 feet in length and 16 feet wide. The total additional length of
compost to be laid out each day is up to approximately 68 feet. The amount of new woodchips (or other
bulking material) required to construct a one -foot thick pad for the compost is approximately 2.3 7 cubic-
yards/day.. Unscreened compost is required in the amount of approximately 4.4 cubic yards/day to cover
the pile 18 inches thick. Capacity calculations for the overall facility are as follows when assuming 1,500
lbs. per cubic yard dry weight of wet compost for 15 day cycles at 131 OF. The compost facility, capacity
will be up to approximately 19,165 wet tons of compost a year.

Compost Recipes
The various blends and mixtures of compost are developed based on proprietary mixes and blends
developed by Earth Farms LLC depending on the feedstocks available and the specific end uses.
The compost blends are made from a mixture of hardwood tree waste, land clearing debris, yard and leaf
waste, dewatered grease trap wastes, and vegetative wastes from food operations. The ground yard waste,
hardwood tree waste, and land clearing debris is added to increase carbon levels. The table below is used
to define characteristics of raw materials that may be incorporated in compost mixture.
Typical ratio used are:
• 1-6 Dewatered Grease Trap waste to Carbon source
• 1- 6 Dewatered Septage to Carbon source
• 1- 4 Food and Vegetative waste, or food waste to Carbon Source

Proportioning of Feedstocks
The compost is manufactured from a mixture of Substrate (the non-putrescible materials) like hardwood
and softwood chips and sawdust, ground yard waste, etc. with the feedstock (the putrescible materials)
like animal bedding, FOG wastes, pre and post -consumer food waste, vegetative/agribusiness wastes.
All the Feedstock (putrescible material) are mixed and blended with a suitable Substrate (the non-
putrescible materials) in the concrete mixing pit on the day of arrival to prevent nuisance problems.
The substrate materials (Wood chips, yard waste etc.) for staging purposes are stored in the raw material
storage areas for subsequent use as needed.
Feedstocks and Substrates are measured and added into the mixing pit in increments of 5 cubic yards
using a front -loader to achieve the required ratio. Feed stocks and substrates are mixed by combining
feedstocks and substrates directly on top of each other in the concrete, water sealed mixing pit. And then
flips and mixes the compost mixture by rolling and fluffing material with the front loader bucket.
The blended compost materials are then transported and placed on a windrow compost production pad
area.
On the pad the windrows continue the composting process that takes approximately 30 days, the
windrows are regularly turned (Mixed) to meet and maintain required time, temperature and turns as

required by our permit. At the end of the composting process, once compost has met all time, temperature
and turns required the PFRP/VAR compliant compost is moved to the finished compost, storage pad area
for curing. The finished compost is stored on the curing pad for further curing and stabilization.
Process Flow Diagram
Process Duration
On day of arrival, the non-putrescible materials are stored in the raw material storage areas for subsequent
use as needed for staging purposes.
On day of arrival Feedstocks are offloaded into one of the mixing pits, and then the pit operator using a 5
Cubic Yard front -loader blends the feedstock with the Substrate at the required ratios.
Then mixes the compost blend by rolling and fluffing material with the front loader bucket.
The materials are then transported by loader and placed on the windrow pads.
The windrow compost process continues in these open windrows for approximately 30 days for
placement to product.
At the end of the composting process, the PFRP/VAR compliant compost is moved by a loader and or
dump truck onto the finished compost storage pad for curing. The finished compost is to be stored on the
South and East end of the composting area for future use approximately 180 days.
Composting Method
�� earth
,farms
ORGANICS
COMPOST d TOPSOIL PRODUCTS
Once formed into a windrow, compost must come to temperate at 130 degrees Fahrenheit for a minimum
of three days. Temperature of piles is monitored daily using a 36-inch temperature probe that is inserted
into the mid center of the windrow every 20-30ft. the temperature of each windrow is recorded in a log
each time it is taken. Once temperature is held at a minimum of 130 degrees, not to exceed 170 degrees
for a minimum of three days, the CAT Loader is utilized to turn the windrow in its entirety. This process
repeats every three days, for a minimum of five times over a 21-day period. Once PFRP is successfully
completed, compost is moved from windrows and placed in a static curing pile for no more than 180 days.
Surface Water Control Features
The composting pad is graded at a 2% grade slope to ensure natural drainage, evaporation of surface
water. All stormwater and run-off are contained and managed by windrow pad earthworks berms. No
stormwater or run-off exits the pads. The water is collected via sump pump, back into the SDTF process,
where it is treated for permitted land application. Run-off of any exterior water is prevented due to pad
earthworks. Landscape buffers berms are placed around operating pads to prevent potential run-off water.
Compost windrows are positioned parallel to the grade on the pads in a manner to prevent the
contamination of completed windrows.
Process and Contact Water
The site plan indicates that compost production areas/pads are sloped toward a runoff collection area.
Excess runoff will be returned to the compost windrow areas as liquid or lime stabilized and land applied.
Content of the collection area or shallow basin are removed as needed and are normally incorporated back
into compost batch as a liquid and nitrogen source or are allowed to evaporate. Any addition of run-off
water back to the windrow is carried out in the primary loading of the windrow and results in an
additional full processing and heat cycle which results in the Process to Further Reduce Pathogen (PFRP)
to be repeated.
Compost Amendments
No amendments outside of soil and sand are added to compost.
Dust and Air Emissions
A water truck with a fan like sprayer on the rear of the truck will pump and spray roads to reduce dust on
roads and pathways.

Composting Process
The composting process at the Earth Farms Zebulon Compost Facility is depicted on the site plan
showing the processing area, the concrete mixing pad, the compost production windrows, the curing area,
and may be described as follows:
• Dry raw materials such as yard clearing waste, wood chips, and bedding material are received and
stored prior to use in "dry material" storage areas.
• These materials are combined with a daily delivery of wet raw materials and the dewatered
materials generated on -site.
• The dry materials are placed directly into the mixing pit and the wet or processed septage/grease
trap materials are placed over the top of the material, these materials are mixed and blended using
a loader at the required ratio's.
• These materials are mixed in the mixing pit.
• The proper ratio of material introduced onto the mixing pit is determined by the number of
"buckets" of material placed by the loader.
• The bulk mixing operation thoroughly combines the raw material and "mixed" raw materials are
transferred to the compost production area.
• After initial treatment in the compost windrows for PFRP and VAR compliance, the compost is
removed to the initial storage area, where it is allowed to complete the compost curing process.
• The critical flow duration in the active windrow is 15 days at required temperature with 5
consecutive turnings as required in rule.
• Typical time in an active windrow will be 4 to 6 weeks to allow for temperature to rise from
ambient to thermophilic.
• Curing and storage may require between 2 and 4 months depending on the season and the end
use.
• Mixing and blending will be accomplished in a 24-to-48-hour duration.
Screening for Unacceptable Waste
All incoming loads of waste will be screened by the site lead. Visual inspections will be made by these
personnel to ensure that any waste brought to site is acceptable. If large batches of food waste, both pre
and post -consumer, are brought onsite, mechanical inspection may be necessary to determine that the load
does not consist of unacceptable waste. No unacceptable waste will be permitted to be stored on site.
Waste generator will be informed of unacceptable waste and asked to remove it from site. Any plastic or
other inorganic contamination found in incoming waste, that is removed is placed in dumpster and taken
to landfill for final disposal.

Special Feedstock or Residual Handling
Earth Farms Zebulon accepts and processes grease trap waste and septage. This is dewatered on site at our
SDTF-32-03 and SDTF-36-15.
This feedstock is derived through the following process. The incoming septage and Grease trap waste is
brought in via pump truck and offloaded at our onsite SDTF dewatering facility in Durham. The waste is
pumped into a bar screen to remove any inorganic foreign objects. Once passing through bar screen,
waste flows into a "grit box" to remove any rock grit, or trash items. Once ran through grit box, the the
waste is pH adjusted, and treated with polymer then pumped into dewatering treatment boxes. The water
that filters out of the dewatering boxes and is pumped to the sewer system to be treated at Durham POTW
water treatment facility. The solids cake left in the dewatering boxes transported from the SDTF in
Durham to this composting site in Zebulon and offloaded into the mixing pit and used as a Feedstock in
the compost blend where it is mixed with substrate material in the mixing pit.
Amendments and Grinding
No amendments are added to the compost. Once fully cured and screened some of the final finished
compost is mixed with loose Dirt, sand, stone chips etc. to make different garden blends or topsoil blends.
Currently no grinding on shredding of material occurs to prepare material for composting.
Pile Sizes
Feedstock, curing, and final product storage piles will be no more than 50ft wide and 30ft high. They will
be monitored for temperature, moisture, and contamination. Composting windrows will be no more than
8ft in height, 16t in width and will generally be between 50-100yds long, contained within permitted
areas. The rows will be separated by 15 ft to allow access for water trucks and front-end loader.
PFRP Compliance
Temperature will be monitored closely at 20%, 40%, 60%, and 80% of windrow length in all active
windrows and recorded daily. Metabolic or biological activity increases with increasing temperature. The
optimum temperature range for composting is between 130 degrees Fahrenheit and 160 degrees
Fahrenheit once the process has begun. As stated in the North Carolina Solid Waste Compost Rules
section .1406, the facility shall maintain the compost process at a temperature above 131 degrees
Fahrenheit for 15 consecutive days or longer, with 5 turnings and the average temperature during that
time shall be higher than 131 degrees Fahrenheit to ensure the highest level of pathogen reduction. If
windrow material does not reach operating temperature, investigate windrow for moisture content,
porosity, and thoroughness of mixing. Compost managed at the required temperatures will favor
destruction of pathogens.
Probe Thermometer and Calibration
The temperature monitoring probes consist of 36- to 48-inch-long dial stem thermometers. Temperature
monitoring shall be accomplished at the 24-to-30-inch depth at each monitoring location. A probe type
dial stem thermometer (as manufactured by REOTEMP) with a 36" stainless steel stem will be needed to
monitor the temperature of the compost. Ice Calibration Method. Fill a tall glass to the top with ice cubes.
Add pre -chilled water to just below the top of the ice. Stir for about 15 seconds. Insert the thermometer
stem or probe 2" into the center of the ice bath and stir gently for another 15 seconds, keeping the stem
surrounded by the ice cubes and moving constantly. An accurate thermometer will read 32°F. Don't let
earth

ORGANICS
COMPOST d TOPSOIL PRODUCTS
the thermometer rest against the ice or you'll get a low reading. Don't let the thermometer rest against the
glass or you'll get a high reading. Don't measure the temperature of the clear water below the ice, as it
may not be 32DF. Adjust fixture on the back of the temperature probe if gauge is not reading at exactly
32DF. Record date, time, and parameters of calibration in Windrow log and site logbook.
Observation of Moisture, Oxygen, Porosity, and C.NLevels
Laboratory analysis of compost is conducted every 120 days. The laboratory analysis investigates
moisture content, 02 levels, porosity, C:N ratio, pathogen reduction, metal analysis and germination. The
sample is a composite sample of finished compost. The sample is collected under sanitary,
uncontaminated conditions using sterilized equipment and environments. The sample is overnighted to
A&L Great Lakes laboratory for examination and is tested within 24 hours of receipt. Additionally,
Solvita testing may be conducted when needed onsite to determine ammonia and carbon levels indicating
maturity and stability. Regular daily on site hand squeeze tests are done to estimate moisture content.
Aeration
Aeration is achieved at multiple points throughout the composting process. Mixing the compost with
CAT front end loader is necessary to ensure that all particles are exposed to high temperatures to
inactivate potentially pathogenic microorganisms. The mixing aerates and redistributes air pockets to
ensure proper oxygen levels for the composting process. The mixing is complete by rotation of the
composting mass. Mixing in the windrow with the turner assures that all particles in the compost mass are
exposed to the required temperatures for the required period. Composting is dependent on the amount of
oxygen supplied by aeration. Aeration will be executed dependent on PFRP and temperature reading.
Active windrows and active curing piles will be monitored and either turned by the turner (windrows) or
rotated and turned by the loader (curing piles), windrows are turned approximately every three days or as
amended by temperature and moisture conditions.
Compost Testing
Laboratory analysis of compost is conducted every 120 days. The laboratory analysis investigates
moisture content, 02 levels, porosity, C:N ratio, pathogen reduction, metal analysis and germination. The
sample is a composite sample of finished compost. The sample is collected under sanitary,
uncontaminated conditions using sterilized equipment and environments. The sample is overnighted to
A&L Great Lakes laboratory for examination and is tested within 24 hours of receipt. Additionally,
Solvita testing is conducted on a monthly basis onsite to determine ammonia and carbon levels indicating
maturity and stability. Regular daily on site hand squeeze tests are done to estimate moisture content. The
sample should be processed within the hold time required by the lab testing procedure, and this is usually
24 hours. The sample that is collected for metals analysis is to be collected and composited over a six-
month period (or every 20,000 tons produced) from each batch of compost. See Rule .1407(b)(4) for
procedure.
End Use
Finished compost will be utilized as a component of bioretention mix in stormwater systems, as a medium
for plant growth, as a landscape material and for agricultural, horticultural, or silvicultural substrate. Sold
to Landscaping companies as Compost, or as Topsoil, or ad a Garden blend. All compost materials will
earth

ORGANICS
COMPOST d TOPSOIL PRODUCTS
be certified as PFRP and representative samples of the material will be tested as accomplished by NCDA
for organic matter, nutrient, regulated metal, and salt levels.
Disposal Contingency Plan
In the event that product is deemed to be of "poor" quality, the compost will be added back to new
production of compost and undergo the composting process over again. This includes PFRP, temperature,
oxygen, and moisture monitoring and screening. If any material was determined to be undesirable and
not suitable to be reprocessed, it would be taken to landfill for disposal. High quality and compliant
product that meets all requirements is removed from site and taken to market by either truck and trailer or
by dump truck. It is in a stable and mature state when removed from the property. Compost or compost
products are loaded onto truck by front wheel loaders. The material is tarped in the bed of the truck and
hauled off.
Record Keeping
Per Rule .1406 (1)(b), Rule .1406 (19)(c), and Rule .1408, a copy of the permit, plans, and operational
reports are maintained at Earth Farms at all times. Annual training documents for facility staff, including
a review of the operations plan and permit documents are maintained on site. Temperature log forms, and
PFRP tracking forms are kept in an orderly manner and kept on site at all times.
Surface and Process Water Control
A small bermed area at the low point on the pad collects any surface water from the compost windrow
pads. Any water that collects against the berm will be removed as needed and will normally be
incorporated back into compost batch. The addition of any collected pad surface water to any compost
windrows to add moisture will restart the PFRP process at the time the pad surface water is added to the
compost. Pad surface water can also be lime stabilized and land applied.
Documentation to Local Fire Protection Agency
Fire Prevention Plan
Temperature, moisture, and pile size will be monitored and remediated, if necessary, in order to prevent
fires. Site monitors windrows for hot spots and if any are identified they are addressed before they can
develop into a fire. In the event of an accidental fire, the local fire emergency services will be
immediately contacted for assistance. If employee safety is not compromised, water truck and excavation
equipment will be utilized to assist in putting out the fire. Any fire will be reported to the Solid Waste
Section within 24 hours, followed by a written notification of the details of the fire within 15 days of the
incident.
Sanitary Operating Conditions
Vector and nuisance conditions will be addressed by maintaining proper cover over windrows to prevent
vector attraction. Facility is located in rural, agricultural area, and due to the size of the property any noise
nuisance is greatly limited. Dust control, if needed, will be achieved by wetting roadways and other
surfaces generating dust. At the end of each operating day, the unloading area will be cleared, and all

feedstocks will be processed/mixed or properly stored. Listed below are some maintenance practices that
will be implemented to ensure the maintenance and cleanliness of the facility. Do not allow any
equipment that exceeds design load limits on or within twenty feet of the pads. Maintain all electrical and
mechanical equipment in good operating condition by following electrical codes and manufacturers
recommendations. Inspect and repair grounding rods, switches, wiring, and all vehicles and equipment
involved in the process. Fences, railings, roofing, and/or warning signs must be maintained to provide
warning and prevent unauthorized entry. Keep the area around the composting facility mowed and free of
tall weeds and brush. Repair any vehicular, vandalism or animal damage. Inspect and maintain runoff
control structures. Clean and maintain compost production areas as required to maintain a pleasant work
environment. Clean and dry any spills, from wet material immediately to sustain safe work environment.
Contingencies for Wind, Heavy Rain, and Extreme or Unusual Conditions
Wind:
• Windy conditions should have little effect on composting operation since windrows are in open
areas.
However, in windy conditions, special attention must be given to the temperature of windrows,
and care must be taken during the loading of raw materials (especially light materials) .
It is anticipated that the local topography and perimeter tall tree vegetation will tend to block a
great deal of the wind from the facility. However, if windy conditions are demonstrated to have a
detrimental effect on the continued processing of the compost, the impacted tasks will be halted
until the wind subsides.
Freezing Conditions:
Operation in freezing conditions requires more frequent inspection of the pads to ensure that any
rainwater is not able pool on the concrete pads or windrow areas.
Additional caution in operation of the turner loader is necessary during conditions where ice may
have formed on the site frozen raw materials should not be added to the mix.
• Windrows generate heat and prevent freezing.
Extended Power Failure:
• Operations during an extended power failure may be accomplished using portable generator.
Temperature monitoring of the composting windrows during a power failure must be continued,
and any compost which does not meet the temperature criteria must be reprocessed.
• Most of the composting equipment is diesel powered, like the windrow turner, screeners, loaders
etc. So power failure will have little impact on operations.
Fire:
In the case of a fire, immediately notify the local fire department.
If employee safety is not compromised, the company pump truck may be utilized to extinguish
fire.
• Compost is monitored for hot spots and if identified are addressed by site personnel.

Equipment Breakdown:
In the event of a breakdown of the compost equipment, delivery of raw materials from the onsite
treatment facilities should be suspended until the equipment is repaired or replaced and material
passes all VAR and PFRP requirements.
Site Safety Procedures
Upon entering the site, the speed limit is 15mph. Heavy Equipment has the right of way. All vehicles and
equipment when not in motion or in use must be placed in the "park" position and parking brake applied.
All personnel, employees, patrons, and guests must wear reflective gear at all times while on the Earth
Farms property. When operating in conjunction with vehicles, loaders will sound horn upon approach and
exit. When passing at pinch points, all vehicles will sound with a horn blast and the opposite vehicle will
sound horn in response. Spill kits and hazardous disposal kits will remain in place and ready around site
at any potential safety hazards. First aid kits and Eye wash stations are available. All staff participate in
monthly LMS safety training, and regular tail gate safety meetings are held to discuss relevant topics.
EH&S Director from Wind River Environmental does routine site visits and inspections. Site manager
does monthly site inspection including EH&S topics and areas.
Cease Operation Procedures
Per Rule .1410, if the compost facility ceases operations, Earth Farms shall meet the following
conditions:
1. All feedstock and unfinished compost materials shall be removed from the site and taken to a
permitted solid waste or composting facility within 180 days.
2. Finished compost materials left onsite shall comply with G.S. 130A-309.05.
3. Earth Farms shall notify the Division in writing upon completion of the requirements.
Odor Control

Odor Migration
Activity such as mixing, and movement of in process compost and feedstocks should be schedule to
minimize the impact of odors. Accomplish these activities early in the workday to take advantage of
rising air currents. Avoid doing these activities on hot, still days or holidays and weekends. Typical windy
conditions or early morning hours are better times to conduct such activities. Monitor the wind direction
and postpone activities that may release significant odors when the wind is blowing towards the most
sensitive neighbors. Facility is located in mostly agricultural area with buffer and distance from nearest
residential homes. Composting can continue year-round, even during cold weather. Seasonal and weather
variation may require operational adjustments that compensate for the change in weather conditions. Cold
weather can slow the compositing process by increasing the heat loss transfer rate form the composting
operation into the atmosphere, but the insulation layer should mitigate most of this transfer. The lower
temperature reduces the microbial activity, especially near the surface. This, in turn, decrease the amount
of heat generated. Warm weather enhances water loss due to evaporation from the windrows. Water
should be added if material become too dry (moisture content drops below 40%). Again, the loss should
not be excessive from the windrow, and controls can be implemented by scheduling turning operation or
adding moisture as required. In event excess liquid accumulates on the site because of rain and wet
weather. That excess liquid will be collected, lime stabilized, and land applied.
Odor Monitoring and Data
Composting site lead conducts site inspections to monitor and address the many routine site management
and maintenance requirements. This includes monitoring for any change or increase in odor. In the event
of odor complaints, an Earth Farms representative will immediately investigate the matter and take every

Odor Control Design and Best Management Practices
The standing SOP (standard operating procedure) for our site consist of a multifaceted list of checks. This
check list takes many factors into consideration when receiving feedstocks (especially new ones), turning
windrows, and mixing materials. The list consists of:
• Wind direction
• Rain falls
• Moisture content
• Time of day
• Overall odor strength of feedstock
• Any other inhibiting weather conditions
Personnel are trained by an experienced, USCC trained manager or supervisor to ensure full
understanding of the processes and potential fault points. Feedstocks are received and checked by
compost technician. Characteristics that are checked when receiving feedstocks are: permit permitting
material, viscosity, moisture level, and smell. Feedstocks are only received during business hours so that
mixing can occur immediately. Avoiding overly wet feedstocks and compost. The use of relatively coarse
co -composting materials that allow oxygen diffusion into the pile can help avoid odor problems. Activity
such as mixing, and movement of in process compost and feedstocks should be schedule to minimize the
impact of odors. Accomplish these activities only early in the workday to take advantage of rising air
currents. Avoid doing these activities on hot, still days or holidays and weekends. Windy conditions or
early morning hours are better times to conduct such activities. Monitor the wind direction and postpone
activities that may release significant odors when the wind is blowing towards the most sensitive
neighbors. All the putrescible material is mixed and blended with a suitable substrate on the concrete pit
on the day of arrival to reduce nuisance vectors. Compost piles are monitored daily for moisture content.
When needed, water can be added via water truck to rows. Aeration is done through turning the windrows
with the loader. The windrows will be turned at least 5 times within a period of 15 days while the rows
are above 131 F°. Any standing water is collected via pump truck.. Minimize dust, which can transport
odors. As and when needed covering the upper third of the windrow with either 3 to 6 inches of finished
compost, 3 to 6 inches of a stable compost, or a carbon rich material such as woodchips. Odor control
Capping piles with fresh carbon source and/or finished compost. All the putrescible material is mixed and
blended with a suitable substrate in the concrete pit on the day of arrival to reduce nuisance vectors.
Sufficiently turning piles on a regular schedule and ensuring that they are properly aerated. Turning is
done during low prevailing wind speeds. All standing rainwater will be collected and managed as they
arise. Moisture levels, temperature, and pH levels will be monitored daily.
