Introduction
In 1999, the Burlington City council agreed to allocate funds to construct a small-scale compost
facility at the South Burlington WWTP capable of processing 5.5 dry tons of biosolids per day.
Although the compost facility would not be large enough to compost 100% of the daily sludge
production of the wastewater plant, it would be large enough to answer some important questions such
as:
1. Could the City produce a quality and compliant compost at a reasonable cost?
2. Is the local demand for compost enough to warrant an expansion of the compost
operations?
3. How will the cost of processing compost to a Class A residual compare to the cost of
hauling Class B sludge from year-to-year?
Construction on the compost facility began in 2001 and the first sludge was dewatered in 2002. The
compost facility operated in a ‘test’ mode in the time between the completion of construction and the
time the permit to operate a compost facility was received from the NC Department of Environment
and Natural Resources in September of 2003.
This annual report has been assembled as a condition of the Distribution of Residual Solids ( 2T )
Permit, #WQ0021632.

II. PROCESS DESCRIPTION
The goal of the Compogro compost facility is to consistently produce a Class A EQ material that is
suitable for a variety of uses on land that has no post-application restrictions. Class A residuals have
the greatest degree of pathogen reduction and are considered to be very safe. All domestic residuals
which are to be distributed to the public for use for landscaping must meet one of the alternatives for
Class A pathogen reduction found in 40 CFR Part 503.30.
Class A pathogen reduction must meet one of the following criteria:
1.A fecal coliform density must be less than 1,000 MPN (most probable number) per gram of
total solids (dry weight)
OR
2. A Salmonella sp. bacteria must be less than 3 MPN per 4 grams of total solids (dry weight)
https://synagro-my.sharepoint.com/personal/rroth_synagro_com/Documents/Desktop/NC/Burlington/2022 Burlington Class A Renewal/Add Info Req/In depth Compost Facility Narrative.doc
- 3 -
The City of Burlington has selected the former criteria (fecal coliform <1,000 MPN) as the preferred
method to determine compliance with the pathogen reduction requirements. This is achieved by
following the time and temperature guidelines in 40 CFR 503.
In addition to the pathogen reduction requirements, Compogro must also meet all of the Vector
Attraction Reduction (VAR) requirements of Class A residuals. All domestic residuals which are to be
distributed to the public for landscaping must meet one of the alternatives for vector attraction
reduction listed in 40 CFR 503.33. The City achieves compliance by following the time and
temperature guidelines provided by the USEPA.
The City of Burlington Compogro Compost facility has developed a system for building aerated piles
and collecting and recording data necessary to ensure that all the requirements of Class A compost are
being achieved.
III. RECORDKEEPING PROCEDURES
A record of the aerated static pile temperatures is enclosed to demonstrate that the piles meet the
required temperatures for the designated time to achieve pathogen reduction and vector attraction
reduction. The document is titled Compost Pile Temperature’s. Aerated static piles are assigned an
identifying number that establishes the date that the pile was built, and the blower that was used to
aerate the pile. The format is year, month, day, and blower number. For example, the number
030109-07 would indicate that the pile was started on January 9, 2003 and was aerated using blower 7.
Each pile is monitored for temperature with at least four thermometers. We are satisfying the 40 CFR
503 pathogen reduction requirements by keeping the compost above 131 degrees F for three (3)
https://synagro-my.sharepoint.com/personal/rroth_synagro_com/Documents/Desktop/NC/Burlington/2022 Burlington Class A Renewal/Add Info Req/In depth Compost Facility Narrative.doc
- 4 -
consecutive days (72 hours minimum). We are satisfying the 40 CFR 503 vector attraction reduction
requirements by keeping the compost above 104 degrees F and an average of greater than 113 degrees
F for a minimum of fourteen (14) consecutive days. In reviewing these logs you will see that we are
maintaining the aerated static piles for longer than 21 days, and keeping the temperatures elevated for
longer than the regulations require. The piles on the Compost Pile Temperature log sheet were
followed onto the curing piles and into the finished compost product piles.
The City has included copies of residuals analyses for the finished compost product from American
Testing Technologies Inc. All of the results support the EQ designation of the compost and are
included in a separate section of this report.
IV. “COMPOGRO” COMPOST SAMPLING PROCEDURES
The Static Aerated Piles
The aerated static piles are constructed under a roof to protect the pile from wind and rain. Before
building the pile, the base or bed is made with a 4 inch perforated airline placed down the center of the
bed. The airline is connected to a blower creating positive or negative pressure so that air can be
forced or pulled through the compost pile. The blowers are controlled by timers that turn themon or
off as needed to supply airflow to the piles. After thebiosolids and amendment (wood chips and
leaves) are mixed together, the mixture is placed on the 4 inch perforated pipeto build the static
aerated pile and to begin the composting process. The mixture of biosolids and amendment is then
covered with a six to eight (6 – 8) inch blanket of amendment to insulate the pile.
After building a pile, a minimum of four (4) thermometers with 48-inch probes are placed at various
locations and depths throughout the pile to monitor the temperatures of the compost pile. The
https://synagro-my.sharepoint.com/personal/rroth_synagro_com/Documents/Desktop/NC/Burlington/2022 Burlington Class A Renewal/Add Info Req/In depth Compost Facility Narrative.doc
- 5 -
temperaturesare recorded daily to track the composting process. Results are entered into a database to
track each pile with a unique identifier to make sure it meets the regulatory requirements. The
thermometers are left in place during the time required to achieve compliance with the time and
temperature requirements for the process to further reduce pathogens (PFRP) and for vector attraction
reduction. We have not had any trouble reaching the prescribed time and temperature requirements in
our static piles.
Curing and stabilization
After our static compost piles have met the requirements for time and temperature, the compost is
moved to the curing pile for a minimum of 21 days for further stabilization. We keep one thermometer
in the curing pile (which can be a combination of several aerated static piles) and record those
temperatures as well. We have found that the curing process often requires more than 21 days and may
take as many as 50 days.
Sampling Finished Compost for Fecal Coliform, Metals and Nutrients
After the curing process is completed the material is screened to separate the reusable amendment
from the compost. At this point the finished compost is ready to be sampled and analyzed for fecal
coliform to demonstrate successful pathogen reduction. The finished compost pile is sampled for fecal
coliform in the following manner.
A core sampler is disinfected for use to collect the samples. The core sampler is used to take core
samples within the compost pile at different depths and locations through out the compost pile to get a
good composite sample of the product. We collect four (4) cores in a sealable plastic bag or sterile
https://synagro-my.sharepoint.com/personal/rroth_synagro_com/Documents/Desktop/NC/Burlington/2022 Burlington Class A Renewal/Add Info Req/In depth Compost Facility Narrative.doc
- 6 -
fecal bottle to make one composite sample, and collect a minimum of three (3) composite samples for
each batch of finished compost. That means that we are taking samples of twelve (12) different
locations in the pile.
The fecal samples are collected in sterile fecal bags and are sent directly to the lab for analysis. The
samples are hand delivered to the Cityof Burlington wastewater lab (Certificate No. 188). A dry
solids analysis and the fecal test require about four days turnaround from sample collection to
reporting of the data. Sample results are recorded and laboratory reports are maintained in the files.
Similar sampling techniques are used to collect samples for nutrient and metals analyses. Those
samples are contained in the sealable plastic bags and sent to American Testing Technologies, Inc. in
Akron, Ohio. A sample is also collected and sent to the NCDA&CS. This data will be used to
formulate the information sheets that are given to the purchaser of the compost. These analyses will
be performed within 60 days of distribution of the finished product, and the results will be maintained
on file.
Test for Re-growth of Fecal Coliform
If the compost is not distributed within 60 days of an acceptable analysis, the pile will be resampled
for fecal coliform using the same technique described above prior to distribution.

Operations and Maintenance Plan
Operational Functions
The operational function of this program involves belt pressing sludge from the South
Burlington Wastewater Treatment Plant by Compost Facility staff and mixing the cake material
with woodchips and leaves to make permit compliant Class A compost that can be sold to the
public. This requires;
Having reliable operational equipment in place
Having trained staff
Belt pressing sludge to make cake material
Having amendment onsite to mix with cake
Collecting all permit required sampling
Record keeping
Safety Measures
The City of Burlington has an established safety program in place that employees are
refreshed yearly on.
This facility is inspected yearly by the City of Burlington’s Safety Director and all findings
are addressed and corrected to his satisfaction.
Signage is employed to warn the public or any visitors of dangers, exits and restricted
areas.
The entrance to our Compost loading area is closed off with a cable that is controlled by
facility staff
The loading area is marked and while loading is taking place the public remain inside
their vehicles.
When loading is complete, the buyer must cover the load with a tarp or other type of
cover to prevent loss of compost during transport.
There are no keys left in equipment after hours of operation.
The breaker for the Kuhn mixer is off in the control building at all times unless we are
making compost.
Our compost area is protected from fire by a dry sprinkler system that is inspected
yearly by an outside contractor. All issues are corrected as soon as possible by this
contractor.
Before the sale of compost is complete, all buyersare provided with a Utilization
Agreement which includes agronomic analysis. This agreement lists all the permit
requirements and conditions that the end user must follow.
Equipment Maintenance Schedule
General MaintenanceofCompost equipment is handled by Compost Facility employees
on an as needed basis. Complex maintenance or repair is handled by the Water Resources
Dept. Plants Maintenance Division. All maintenance on our John Deere loader and Freightliner
tandem dump truck is scheduled by the City of Burlington’s Equipment Services Division while
maintenance on the Erin Screener is handledby an outside contractor once per year.
Sampling
The City of Burlington’s Residuals Management Coordinator or his designee will schedule
and collect all permit required samples and follow all Chain of Custody.All sample data and
records are kept onsite at the Compost Facility.
Nutrient and Metal samples will be collected as required for permit compliancefrom
each finished compost pile and sent to contract laboratories for analysis.
TCLP will be collected once per yearand sent to a contract laboratory for analysis.
3 composite samples with each composite sample consisting of 4 core samples will be
collected on each finished compost pile to run fecal coliform analysis to determine if the
