Good Things are Happening in Durham
Section 4 – Operations Plan for Composting
(15 NCAC 13B.1406)
4.1 General Facility Operations
4.1.1 Composting Overview
Composting is the controlled aerobic decomposition of organic materials by microorganisms into a stable, mature soil-like end product (compost). The City of Durham compost facility uses the
turned windrow method of composting, wherein organic materials are mixed and formed into
triangular-shaped windrows and turned periodically to reaerate the windrow, release heat and
moisture, and to maintain porosity. 4.1.2 Contact and Facility Information
Any questions or correspondence regarding the Durham facility should be directed to:
Donald Long Director, Department of Solid Waste Management City of Durham 1833 Camden Avenue Durham, NC 27704
Tel: (919) 560-4186
Fax: (919) 560-1228
Email: Donald.Long@durhamnc.gov The compost facility is open Mondays through Fridays from 7:30AM until 4:00 PM. On
Saturdays, the facility is open from 7:30AM to 12 Noon.
4.1.3 Access Control Access to the Durham compost facility is limited to normal operating hours (see above). Outside
of normal operating hours, the entire Waste Disposal Center is closed, with locked gates and
video camera security at several points. The entire facility is fenced off to prevent unauthorized
access. 4.1.4 Signage
Several signs containing the information required by NC DEQ-DWM have been placed near the
public entrance to the City's Waste Disposal Center, indicating hours of operation, permit numbers and acceptable and non-acceptable wastes.
4.1.5 Fire Management
Fires can start in composting facilities through three primary mechanisms: spontaneous
combustion in compost piles that have excessively low moisture content, carelessly discarded cigarettes/cigars, and fires caused by internal combustion engine malfunctions. Fire potential will
Good Things are Happening in Durham
be reduced at the Durham Compost facility by careful attention to moisture content in the
windrows, sizes of storage piles (less than 12 feet high by 25 feet wide and 200 feet long),
enforcing a "no-smoking" rule at the facility, and preventive maintenance procedures on
equipment . Fire extinguishers at the compost facility will be used in the event of equipment-related fires. In the event of fire, the local fire department will be called. Also, the City has installed two City fire hydrants to aid the Fire Department with quick access to a water source if
needed.
4.1.6 Health & Safety The facility will be operated to ensure the health and safety of City staff, contractor staff and the
general public at all times. Open burning is prohibited at the site and any fire observed will be
handled using the facility's fire management procedures. Fire extinguishers will be carried on all
mobile equipment for use in the event of a fire involving a piece of equipment. All personnel at the compost facility will be trained in the safety procedures of the facility and of the City. The City of Durham has several health and safety policies currently in effect. These include:
S201 - Safety and Health Policy S202 - Monthly Safety Inspections of City Facilities S203 - Response to OSHA Complaints and Routine Inspections
S204 - First Aid Kits
S206 - On-the-job Accident Report S301 - General Safety Rules
S-204-1- Employee Drives License Policy FLT-100 - Operation of City Vehicles and Motorized Equipment HRM-714-1 -Alcohol and Drug Testing Requirements for COL Holders
All operations at the Durham Compost facility will be conducted in accordance with these
policies. 4.1.7 Recordkeeping Program
The Durham compost facility will maintain the following records in its operational records:
• Daily records of incoming yard waste • Quantities of unacceptable wastes received (in Ions) and the ultimate disposition of those
wastes
• Estimated composition of the windrow
• Dates of initial windrow formation • Turning dates • Approximate dates when the curing process began.
• Temperature monitoring records for regulatory compliance
• Compost quality analytical laboratory test results, and
• Disposition of product that did not meet regulatory standards.
An example of an operational log form is included in Table 3.
Good Things are Happening in Durham
Good Things are Happening in Durham
An annual report for the period from July 1 to June 30 shall be submitted by the City to the DEQ
Division of Waste Management by August 1 of each year. The report shall include:
1. The facility name, address and permit number;
2. The total quantity (in tons) and type of waste received at the facility during the year
covered by the reports, including tons of waste received from local governments of
origin;
3. The total quantity (in tons) and type of waste processed into compost during the year
covered by the report;
4. The total quantity (in tons) and type of compost produced at the facility, by product
classification, during the year covered by the report;
5. The total quantity (in tons) and type of compost removed for use or disposal from the
facility, by product classification, along with a general description of the market during
the year covered by the report; and
6. Temperature monitoring records to verify compliance with 15A NCAC 138.1406(10).
Monthly reports, which contain daily logbook entries, as well as a copy of the annual report, will
be kept in the official operating record in the City’s Solid Waste Management offices.
Good Things are Happening in Durham
4.2.1 Waste Receipt
Incoming waste shall consist only of yard waste, which is leaves, grass clippings, stems, pruning materials, small brush and biodegradable paper yard waste bags generated in residential and commercial lawn and garden care in the City of Durham, and clean wood waste including
pallets. The waste is to be received and weighed at the scale house, and checked for unacceptable
wastes. Any unacceptable wastes shall be removed by the customer and disposed of in the
designated disposal container at the Recycling Center. Uncontaminated yard waste shall then be unloaded by the compost facility customer at the Waste Receipt Area.
At the Compost facility, the site operator will conduct a second inspection of the incoming yard
waste. Vehicles containing unacceptable waste will be rejected. Any extraneous unaccepted
waste found while unloading or after the customer has left the site shall be placed into a dumpster at the composting facility.
Incoming yard waste will be stockpiled in the Waste Receipt Area on a daily basis. On a daily
basis, facility operators will push the waste, using front end loaders, into windrows, each a
maximum of approximately 12' high by 25' .wide by 200' long, spaced approximately 25' apart to allow room for fire-fighting equipment. Approximately four (4) storage piles will fit in the designated area after allowing for fire lanes.
4.2.2 Feedstock Preparation
At least every week an outside contractor will come in to grind up the accumulated waste in the designated Grinding Area. Ground up material will then be formed into piles for temporary
storage. Under average conditions, the contractor will have to grind about 213 cubic yards per
day. The contractor will have to form two (2) temporary storage piles, each 25' wide x 12' high x
200' long. As these piles will only hold about 1.5 weeks of yard waste grinding quantities, that material which is not diverted to the Windrow Area #1 for composting will be moved off-Site for use as boiler fuel or transferred to out-of-state landfills.
The contractor will grind all the incoming materials together. In the Spring, with the higher
percentage of grass clippings in the yard waste, the natural ratio of high-carbon brushy material to high-nitrogen grass clippings should be about 2:1. If the site operators observe higher amounts of grass clippings in a load; they will "pre-mix" those clippings with previously-ground brushy
material to help maintain the acceptable C:N ratios. In other seasons, with lesser grass clippings,
this step will not likely be needed. The compost recipes used by the City call for the use of small
amounts of urea fertilizer to adjust C:N ratios.
Good Things are Happening in Durham
4.2.3 Active Composting
Composting will be done with the turned windrow method, where the windrows will be built with front end loaders and where windrows will be turned with a front end loader (FEL).
Windrows will be turned a minimum of one (1) time in a 3-day consecutive period once windrow
temperatures have reached 131° F (in accordance with the requirements of 15A NCAC
138.1406(10). Windrows will be turned weekly after that. Aeration in the windrows will be provided by turning and the passive "chimney'' effect of air movement in a windrow with adequate porosity (35-50% free air space). Total windrow residence time is planned to be about
six (6) months for both composting and curing.
4.2.4 Curing
At some point in the future, the City may elect to purchase a windrow straddle-type turner to turn windrows and to optimize processing capacity on the compost pad.
Curing will be done "in-place", that is, the material will be left in the windrow after the active
composting phase is complete. Windrows that have finished composting will be combined for curing to utilize the volumetric shrinkage that occurs during composting to free up additional pad area for active composting.
4.2.5 Screening
Screening will be done by the Contractor with a vibratory screen. Screening rejects ("overs") will be stored in maximum 10' high piles in the Product Storage Area and will be used for internal
purposes by the City of Durham.
Good Things are Happening in Durham
4.2.6 Product Storage
Following final curing and screening, finished compost product is stored in the Product Storage Area. This area is sized to hold six (6) months accumulation of product inventory. "Overs” will be stored in an adjacent storage area.
Both the Product Storage Area and the Screened Overs Storage Area will be about 20' wide by
120' long and consist of a maximum ten (10)-foot tall pile of material covering the storage area. There is no need to windrow this finished material. If the "overs" contain more than 6% inerts, the "overs" will be disposed of at the Transfer Station. The percentage of inerts in the "overs"
will be determined by the methodology specified in 15A NCAC 13B.1408 (a)(5).
4.2.7 Process Monitoring Moisture Moisture content of the yard waste compost will be monitored periodically three times a week
with a "squeeze test". A handful of the fresh mix is squeezed into a ball in the hand; if water
drips out it is too wet. If it crumbles apart after being squeezed, it is too dry. In the event of the
material being too wet, the City will increase windrow turning frequency to enhance moisture evaporation. If the mix is too dry, the City will add moisture by either a water truck or by using potable water. The on-site storm water pond is not to be used for watering windrows.
Temperature
Temperatures are monitored in the composting windrows using a Reotemp™ 36" compost thermometer. Temperatures are monitored Mondays through Fridays (except for holidays) for at
least the first seven to ten days after windrowing to ensure that temperatures meet regulatory
requirements. Temperature data is recorded on the Operational Log (see Table 3). Any
windrow not meeting the 15A NCAC 138.1406 (10) requirement of 55° C. (131 F) or greater for three consecutive days will be torn down and the contents remixed with freshly ground yard waste, thus restarting the composting process.
4.2.8 Staffing
The City will provide an attendant to oversee the facility and seek to retain a private contractor to handle most of the work in processing yard wastes and composting material.
4.3 Environmental Management
4.3.1 Surface Water Control
Surface water control is needed to ensure that rainfall-induced runoff that may be contaminated
with waste materials at a composting facility does not cause water quality problems in nearby
streams. Surface water control will be achieved with an extended detention or bio-retention
pond. This pond will be inspected by Facility staff daily.
Good Things are Happening in Durham
Inspection requirements will address the following at a minimum:
• Inspect plantings • Settling, woody growth, animal burrowing, and signs of piping in the
embankment
• Signs of seepage on the downstream face of the embankment
• Condition of wet detention basin floor, perimeter of the wet detention basin, and grass cover on the embankment • Excessive erosion or sedimentation in or around the basin
• Riprap displacement or failure
• Principal and emergency spillway meet design plans for operation
• Outlet controls, inlet controls, debris racks, and mechanical and electrical equipment • Inlet and outlet channel conditions
• Stability of slopes
• Safety features of the facility
• Access for maintenance equipment • Signs of trespass or unauthorized traffic • Sediment build-up
4.3.2 Odors
Odors (and air quality) will be managed in accordance with 15A NCAC 20, Air Pollution Control Requirements, to minimize fugitive emissions and odors. Odors and dust are the two
main air quality issues associated with composting. Odors will be minimized by careful attention
to incorporating grass clippings into windrows within 24 hours of receipt, ensuring good porosity
in compost windrows, and keeping moisture levels at appropriate levels. In the case of unusual odor conditions, a 6" blanket of finished compost will be placed over the windrows for absorption of odors. This will be accomplished by using a hydrostatic mulch blower and hose to
apply an even layer of compost over the piles.
The key to controlling odors in composting is effective process control and composting management. The City of Durham will be certified as Technically Competent in Composting by the North Carolina Composting Council and will use this training to ensure minimal odors are
present at the facility. To minimize the potential for an offensive odor episode, the staff will
make sure that windrows stay aerobic, that no putrescible solid waste is present in the windrows,
and that windrows are turned on a regular schedule consistent with the Operating Plan. Should an off-site nuisance, odor event occur, the City will provide an emergency phone number
for local residents to call. A 6" blanket of finished compost will be distributed over the windrows
for absorption of odors. This will be accomplished by using a hydrostatic mulch blower and hose
to apply an even layout of compost over the piles. The staff will then review operational logs
and/or daily reports to determine what caused the odor event to occur.
Good Things are Happening in Durham
4.3.3 Vectors
Vectors (i.e. flies, mosquitoes, rodents, etc.) are a potential problem with mismanaged yard waste composting operations. Proper windrow management by regular turning will prevent rodents from nesting in windrows and by turning windrows, fly larvae and eggs are exposed to
the higher interior temperatures of the windrows. Windrows should be turned weekly to break
fly reproductive cycles. Mosquitoes and similar insects that breed in pools of standing water can
be controlled by proper pad slope and drainage (at least 2%). 4.3.4 Dust
Dust will be controlled by avoiding screening activities in dry, windy conditions. A water truck
is available for dust suppression in severely dry weather. 4.3.5 Severe Weather Conditions
Operations at the compost facility will be covered by the City of Durham Adverse Weather Plan,
which calls for cessation of waste collection activities during severe weather events. The solid waste transfer station, however, tries to remain in operation during most weather events. The compost facility is open whenever the Transfer Station is open. The Durham Solid Waste
Adverse Weather Plan is provided in Appendix D.
4.4 Equipment Maintenance All City equipment used in Solid Waste Operations is routinely maintained for proper
performance with a very thorough Preventive Maintenance Program.
4.5 Site Maintenance Maintaining the Durham YWCF site in a good operational condition, is an important part of
successful composting operations. Areas where site maintenance is important are: repairing
eroded and rutted areas, maintaining site access roads, and in making sure the storm water pond
operates properly. Facility staff will conduct a "walk-around" inspection of the whole facility every morning.
Problems will be noted in the operational log and repair work will be scheduled as soon as
practicable. Eroded or rutted areas in the compost pad will be repaired with compacted fill dirt.
Rutted area in the gravel access roads will be repaired with fresh gravel. For observed problems with the storm water pond, a qualified contractor will be called in.

Section 5 – Operations Plan for Wood Waste Processing (NEW)
5.1 General Facility Operations
5.1.1 Wood Waste Processing Overview
Wood waste is collected from residential customers in the City of Durham, from private haulers and from the County of Durham. Generally, the wood waste consists of limbs, grass, leaves,
branches, and controlled amounts of tree trunks (smaller sizes). The City contracts with a vendor
who grinds this material up and places them in windrows according to specifications outlined in
permit to operate 3204-COMPOST-1991.
5.1.2 Contact Information and Hours of Operation
Contact information has been listed in section 1 and is the same throughout this application. The Wood Waste processing area is open for operation from 7:30am to 4:30pm Monday through Friday and Saturday from 7:30am to 12:00pm. The facility is closed on Sunday and all City
observed holidays.
5.1.3 Access Control
Access to the Compost /Yard Waste facility is limited to normal operating hours (see above).
Outside of the normal operating hours, the entire facility is closed, with locked gates and a video
camera security system as specific points. The entire facility is fenced off to prevent unauthorized access.
5.1.4 Signage
Several signs containing the information required by NC DEQ SWS have been placed near the public entrance to the Waste Disposal Center main entrance indicating hours of operation, permit
number, and acceptable and non-acceptable wastes.
5.1.5 Fire Management
Fire potential will be reduced at the City wood waste processing area by carefully attending to
the moisture content and temperature of the windrows, sizes of storage piles, enforcing a “no-
smoking” rule, and preventive maintenance. In addition, two active fire hydrants and two
charged fire extinguishers remain ready for possible fire emergencies. Fire extinguishers will be
Good Things are Happening in Durham
located on all equipment used in the area. In the event of fire, the local fire department will be
called.
5.1.6 Safety and Health
The facility will be operated under established safety and health policies, rules, and regulations
by all applicable jurisdictions. First aid kits are on site in the scale house and will be available
for minor injuries or incidents.
5.1.7 Recordkeeping
Recording keeping will be conducted and kept by spreadsheets on the computer systems in the scale house. Typical records that will be kept are:
Incoming wood waste tonnage
Unacceptable waste received in tons and the disposition of the waste
Temperature and moister observations of the windrows Outbound designation of wood waste
processing
Any issues with the pond liner, fencing, security, or other noticeable events.
An annual report for the period from July 1 to June 30 shall be submitted by the City to the DEQ
Division of Waste Management by August 1 of each year. The report shall include all
information as requested on the form which will be available prior the reporting time. A listing
here of the information to be given to DEQ is being reserved as the forms are changed from year to year. Monthly reports, which contain daily logbook entries, as well as a copy of the annual report, will be kept in the official operating record in the City’s Solid Waste Management
offices.
5.2 Wood Waste Processing Operation
5.2.1 Wood Waste Receipt and Preparation
The only feedstock that will enter the facility and be dumped for wood waste processing is materials consisting of limbs, grass, leaves, branches and small controlled amounts of tree trunks. Larger hydraulic vehicles will be allowed to drive to the site and dump the materials in
the receiving areas noted as area #2 for bushy brush and area #3 for leaves, grass, and similar
material. Area #1, will receive the hand unloading customer’s wood waste material. The
material from area #1 will then be transported by City staff to the appropriate area for proper processing.
At least twice a week, the contractor will come in and grind the accumulated waste in the
designated receiving area and grinding area. Ground up material will then be formed into
windrows. The contractor will have to windrows, each 25’ wide X 12’ high X 200 feet long.
Good Things are Happening in Durham
The windrows are to be 25’ apart to allow for firefighting equipment an access. Approximately
four (4) windrows will fit in the designated area after allowing for fire lanes.
5.2.2 Process Monitoring
Moisture:
The moisture content of the ground wood waste material will be conducted with a “squeeze test.”
A handful of the freshly ground material is squeezed into a ball in the hand; if water drips out of it, then it is too wet. If it crumbles apart after being squeezed, it is too dry. In the event of the material being too wet, the City and or contractor will increase windrow turning frequency to
enhance moisture evaporation. If he mix is too dry the City and or contractor will add moisture
by either water truck or by using potable water. The on-site pond is NOT to be used for watering
windrows. This moister test will be done once a day at the same time either the 8am or the 3pm temperature reading is being conducted (see temperature below).
Temperature:
Temperatures are monitored in the windrows using a reliable 36” compost thermometer.
Temperature will be monitored three days a weeks; twice a day at 8am and 3pm (or as close to the times as possible) using the thermometer. Temperatures are recorded on the spreadsheets kept in the scale house. (See attachment section) Windrows temperature must be in accordance
with 15A NCAC 13B.1406 (10) requirement of 55 degrees Celsius (131+). Typically, these
windrows do not stay in the facility for more that 3-5 days before the contractor removes them
off site. 5.2.3 Staffing
The City will provide a full time equipment operator to oversee the wood waste processing site.
This staff member in the absence of the contractor will “push” up wood waste in preparation for
grinding. In cases where customers dump erroneous material in the area, the staff member will ensure that this waste is removed and placed in the non-wood waste material container. The weight of this non-wood waste material will be reported each month to the Waste Disposal
Manager.
5.3 Environmental Management
5.3.1 Surface Water Control
Surface water control is needed to ensure that rainfall-induced runoff that may be contaminated with wood waste material from processing does not cause water quality problems in nearby streams.
Surface water control will achieved with a bio retention pond. The pond will be inspected by the
City staff once a day, three times a week. The City staff will monitor the pond level to ensure
that its maximum level should remain at or lower than 303.0 monitoring range. The pond liner shall be maintained at the freeboard of the pond.
Good Things are Happening in Durham
5.3.2 Pond Discharge
The City operates under a NPDES local discharge permit (NCG110092), issued and regulated by
NC DEMLR, which allows the pond to drain into the City sewer system. It is a requirement of NC DEMLR to have the pond tested every three months. The details of the testing are contained within the discharge permit. The discharge system is a syphon/pump driven flow
system with a flow meter attached as one of the requirements for the City Water Management
department. Inspection requirements will address the following minimum:
Pond level at 303.0 or lower
Liner damage below the freeboard
No smoking signage
Fire Safety equipment/Fire hydrants
Security fence around the property
Ponds grab samples four (4) times a year. (chemical testing)
5.3.3 Odors
Wood waste processing does not produce the odors that have been experienced with actual Composting. Odors will be monitored, however windrows will not be sitting in the site for more than a five day period before being removed.
5.3.4 Severe Weather Conditions Operation at the wood waste processing facility will be covered by the City of Durham
Emergency Weather Plan, which calls for cessation of waste collection activities during severe
weather events. However, the Solid Waste Transfer Station tries to remain in operation during
most weather events.
5.4 Maintenance
5.4.1 Site Maintenance Maintaining the City of Durham Yard Waste Compost/Wood Waste Processing site in a good
operational condition is an important part of successful composition operations. Areas where
site maintenance is important are: repairing eroded and rutted areas, maintaining site access
roads, and in making sure the pond operates properly. City staff will conduct a “walk-around” inspection of the whole facility every morning. Any
issues noted will be recorded on the temperature/ moister log used by the City employee. Should
the site access road and wood waste pads need repairs, the Contractor will complete the repairs
as per in force contract. Major issues with the pond will be dealt with by qualified personnel.
Good Things are Happening in Durham
5.4.2 Equipment and Equipment Maintenance
The City shall have a bull track dozier on site for pushing up newly dumped wood waste material. The equipment will be able to navigate through dry and wet conditions. It will be maintained by a City operator and if major repairs are needed, it will be repaired by the City’s
Fleet Management department. All City equipment is on a preventive maintenance schedule.
No other equipment belonging to the City will be utilized in the wood waste processing area. However, the contractor will have various necessary heavy equipment in the area to conduct the processing. For example, the contractor may have, on site at any given time to process wood
waste; a grinder machine, a track loader, a rubber tire loader, an excavator, and a semi-tractor
trailer for removing material. This equipment is used to grind and haul wood waste material.
It is a safety requirement that all heavy equipment vehicles used to process wood waste have an on board fire extinguisher or built in fire suppression system.
5.4.3 Land Scape
The City staff will be responsible for cutting grass, weed control, testing of the pond, and all
related reporting.
