GUILFORD COLLEGE
COMPOST APPLICATION RENEWAL (4/6/18)
To whom it may concern;
Guilford College has operated two "in -vessel" small composting units known as "Earth Tubs" since early
2010. These units are currently operated under permit #41-25. The college also operates an approved
curing yard located approximately 800 feet to the north of the two Earth Tubs.
The purpose of this letter is to state that Guilford College wishes to renew its existing permit for a Small
Type III Compost Facility (permit # 41-25) allowing the continued use of the two Earth Tubs and curing
yard to create compost for top -dressing during turf renovations, enhancing the campus grounds and
building fertility on the college farm. This goal is part of the larger sustainability effort at Guilford
College. Beyond the aforementioned goals, this facility allows Guilford College to divert significant
volumes of food waste from the landfill and minimizes the use of petroleum based non -organic
fertilizers.
During the past five years improvements have been made to the Earth Tub facility. Each unit has been
placed on concrete slabs and both have been plumbed to a 125 gallon below ground leachate collection
vessel. All records are maintained on a computer data base.
The facility has been inspected as required and has submitted required reports since receiving its permit
to operate. The facility operates under the area inspected by John Patrone.
Each Earth Tub batch receives up to 3500 pounds of post and pre -consumer food waste from dinning
services located on campus. Leaves collected on campus and sawdust generated by a saw milling
operation also located on -campus and are the primary source of carbon. Clean sawdust generated by
the Theater Department Scene Shop is sometimes utilized as well. Clean wood chips provided by a local
tree service company (Davey Tree) and by our own brush chipper are the only other sources of carbon.
Total food waste processed by both Earth Tubs amounts to approximately 40,000 pounds annually.
The Earth Tubs are managed by me along with some student work-study and occasional assistance from
members of the grounds crew. My contact information is as follows:
David H. Petree Office: 336 316-2904 Cell: 336 451-6638
Guilford College
5800 West Friendly Avenue
Greensboro, NC, 27410

The operational plan for the Earth Tubs Is as follows: Up to three times weekly during periods when the
dinning service is operating, dinning staff bring from the kitchen pre and post -consumer food waste in
covered 30 gallon Rubbermaid containers to the caf6 dock. Each container is weighed. A rubber -tired
front end loader is used to transport the food pulp to the Earth Tubes. The contents are spread in even
layers and covered with saw dust and leaves. Clean wood chips are used as a filter base material.
Layering continues until the unit is deemed full. Monitoring of the temperature with a Reotemp probe
thermometer begins after the unit is full. It typically takes up to two weeks to fill one Earth Tub and
perhaps another week to reach 131 degrees.
When temperatures inside the vessel exceed 130 degrees we begin turning and aerating the material
inside using the rotating auger of the Earth Tub. Turning continues at least twice weekly until all PFRP
and VAR requirements are meet. Presence of actinomycetes is noted when observed. The lenghty
duration of time at high temperature far exceeds the requirements set by rule .2406 (72 hours above
130 degrees), but produces a very high quality material. All leachate is collected in a 125 gallon below
ground vessel and is piped into the city sewer system (see attached letter from City of Greensboro
Storm Water Division).
The contents of each Earth Tub are emptied into a front-end loader and transported to the curing yard
where it is mixed with leaves to generate larger quantities of material. Each wind row is typically less
than 50 cubic yards. Temperatures are monitored until all PFRP and VAR requirements are met. Each
windrow is allowed to cure for approximately four to six months, or until temperatures cool. Material
destined for use on the campus grounds is passed through a compost screener to remove wood chips or
other un-composted debris. This material is re -introduced back Into a new windrow. Cured compost for
use on the college farm is typically not screened.
i have included a copy of the most current inspection report performed by John Patrone.
Please notify me if additional information is required. Thank you for your attention to this matter.
Sincerely,
David H. Petree

Re: Composting Facility
Dear Mr. Petree,
April 18, 2016
You have requested to discharge approximately 1.500 gallons per year of compost
leachate drained from two Earth Tubs for composting at Guilford College. The goal is to
achieve 10016 disposal of .food service waste. Food service waste is supplemented with
other gardening / landscaping waste.
This is regulated by the state as a Type3 composting facility. Tony Gallagher
[phone] NCDENR. Solid Waste Division oversees this facility. It would appear
that this leachate could be beneficially reused on the campus grounds. The additional
regulatory hurdles required make on -site reuse impractical at this time.
The City of Greensboro authorizes Guilford College to dispose of this leachate to the
sanitary sewer via an existing fixture or private cleanout. No access is granted via
manholes or other public fixtures and no material will be. discharged to public storm
drains or conveyances..
Thank you for your help in protecting the City of Greensboro collection. system and
treatment works and the waters of the State.

Mixing
Turn on the auger motor and rotate the cover to shred and mix the new organic material into the active compost Two revolutions of the
rotating cover are required to mix the outside and center of the Earth Tub, The auger will shred and mix a ton or more of compost in 10-15
minutes. During active composting, the Earth Tub should be mixed at least two times per week.
Aerobics and odor control
Maintaining aerobic conditions and controlling temperatures are essential for fast, effective composting and odor control. The aeration system
draws air through the compost and forces the exhaust air through our biofdtration air purification system to remove odors. The overall
cleanliness of the in -vessel design allows the Earth Tub to be placed in commercial settings close to where waste is generated.
Waste reduction
Heat generated in the Earth Tub rapidly breaks down the food scraps. The volume reduction is typically 50% or higher. After 2-3 weeks of
active composting, open the discharge door and remove the compost product The compost can be cured for 20-40 days for further stabilization
if you are blending it into a soil mix.
Key features
• Easy to operate
• Rapid process reduces compost volume quickly
• Heavy-duty plastic construction
• Minimal need for bulking agent
• Short time required for mixing/loading
• Temperature controlled system
• Insulated for cold weather operation
• Thorough compost mixing
• Bio-filter odor control system

8. Each earth tub contains about 3,000 lbs of food waste, 385 lbs of leaves, 120 lbs of wood chips, and 112 lbs of
sawdust.
9. The earth tubs are piped to a 125-gallon buried leachate storage tank. Mr. Petree stated that leachate from the
tank is pumped via transfer pump into an adjacent municipal sewer stormwater drain.
10. The City of Greensboro — North Carolina has authorized the disposal of leachate from the Guilford College small
type III SWC facility to the sanitary sewer. The SWS has accepted the authorization (see file copy letter dated
April 18, 2016 and response email dated April 21. 2016).
11. To achieve process to further reduce pathogens (PFRP), temperature in the earth tubs is required to be > 131' F
for three days. To meet vector attraction reduction (VAR), temperature in the earth tubs is required to be
maintained for an additional 11 days at > 104' F with the average temperature > 113' F.
12. Material remains in the earth tubs for at least 14 days, meeting both PFRP and VAR requirements.
13. Compost removed from the earth tubs is combined into windrows. Two or three tubs of material are incorporated
