2.0 SITING REQUIREMENTS
The New Hanover County Landfill is the location for the small Type 3 compost facility. The Landfill is
located in an unincorporated area of New Hanover County having a County parcel ID R01500-002-
001-001 and a recorded acreage of 701.54 acres. The Landfill is bordered by Fishing Creek to the
north, US Highway 421 to the west, the Northeast Cape Fear River to the east, and a manufacturing
facility (Invista) to the south.
The portion of the Landfill property that contains the compost facility is roughly 80 feet by 90 feet,
located east of Cell 413, roughly 400 feet north of our future convenience site (will be operational in
September 2023), and roughly 450 feet south of the leachate treatment lagoon. The location of the
facility is in close proximity to groundwater monitoring wells 65-04-Z and 65-04-E, which are

immediately to the north and south of the location, respectively. The compost facility location within
the Landfill property is shown on the Facility Site Plan included in Appendix A.
2.1 REGULATORY BUFFER REQUIREMENTS
Regulatory buffer requirements, as stated in rule 15A NCAC 13B .1404, for a small Type 3 compost
facility include:
1. If the facility is located in a floodplain it shall not restrict the flow of the 100-year flood,
reduce the temporary storage capacity of the floodplain, or result in washout of solid waste,
so as to pose a hazard to human life, wildlife, land, or water resources.
2. A 100-foot buffer shall be maintained between all property lines and compost areas for Type
3 and 4 facilities, 50-foot for Type 1 or 2 facilities.
3. A 500-foot buffer shall be maintained between compost areas and residences or dwellings
not owned and occupied by the permittee, except that Type 1 and Small Type 2 and 3
facilities shall maintain a 200-foot buffer.
4. A 100-foot buffer shall be maintained between all wells and compost areas, except
monitoring wells.
5. A 50-foot buffer shall be maintained between perennial streams and rivers and compost
areas.
6. A compost facility shall be located in accordance with 15A NCAC 02B .0200, Classification
and Water Quality Standards Applicable to Surface Waters in North Carolina.
7. All portions of a compost facility located over a closed -out disposal area shall be designed
with a pad adequate to protect the disposal area cap from being disturbed, as defined in Part
(a)(10)(C) of this Rule, and there shall be no runoff from the pad onto the cap or side slopes
of the closed out area.
8. A 25-foot minimum distance shall be maintained between compost areas and swales or
berms.
Buffer requirement 1 and 7 above are not applicable, the compost facility is not located within a
floodplain and is not located on a closed -out disposal area. Refer to attached FEMA FIRM in
Appendix A for the location of the facility and floodplain. The compost facility location exceeds
applicable regulatory buffer distance requirements.
3.0 DESIGN PLAN
Compost of feedstock will be accomplished using Daritech Inc. in -vessel composting system. This
system has the benefit of containing any leachate and odors generated during the compost process,
decreasing the time to meet Process to Further Reduce Pathogens (PFRP)1 criteria, and requires a
smaller footprint than other methods. A schematic of the compost facility is provided as Exhibit 1.
The following sections 3.1 - 3.3 provide a description of the compost components.
1 Process to Further Reduce Pathogens (PFRP). Maintaining a minimal temperature of 131 degrees F (55
degrees Celsius) for at least three days.

3.1 COMPOST FEEDSTOCK
-ommel Screen
Jversize Material I
Approximately 25 tons per week (1,300 tons/year) or 1,400 cubic yards of the following materials
are expected to be processed into Class A compost at the facility:
• Ground yard waste and land clearing debris
• Ground unpainted/untreated lumber and pallets
• Pre- and post -consumer food waste, including meat and poultry products and spent
brewery waste
• Land clearing (inert) debris
• Vegetable and fruit produce waste
• Soiled animal bedding and animal dung/manure
• Animal carcasses
Feedstock will be from select sources providing the compost in -vessel system prescribed
composition of 500 pounds of food and vegetable and fruit produce waste mixed with approximately
800 pounds of ground yard waste and woody material. No analytical testing of the feedstock occurs,
only analytical testing on the finished compost product.

3.2 COMPOST OPERATION
Compost operations will follow the prepared Operations Plan included in Appendix B. In summary, as
a compost feedstock collection vehicle enters the New Hanover County Landfill, it is weighed using
the Landfill's entrance scales and assessed for contamination. The Landfill is selective as to the
type and source of the feedstock. Once accepted, the collection vehicle is directed to the compost
facility to unload. The material again is assessed for contamination during the unloading. Feedstock
is then blended to the appropriate ratios in order to maintain consistency in blends among batches.
Each batch is fed into the in -vessel compost unit and processed (aerated and agitated mechanically)
to attain a minimum temperature of 131OF for at least three (3) days. The batch is then transported
to covered curing bunkers for Vector Attraction Reduction (VAR)2 (each bunker's approximate
dimensions are 12-foot depth x 10 foot wide x 6-foot high. The material remains in the curing
bunkers for at least 14 days at a minimum temperature of 1040F (averaging 1130F). Periodically,
the curing piles are turned over using a wheeled loader or skid -steer to maintain optimum pile
temperatures. After attaining VAR, the compost is transported to a separate bunker for further
curing and storage before release to the public. The in -vessel system, feedstock blending, and
curing bunkers are on a concrete pad and covered with a roof, conveying precipitation away from
compost materials and equipment. A visual representation of the compost process is provided as
Exhibit 2.
The compost facility operator maintains a Managing Composting Programs Certification from
SWANA. The operator also received equipment -specific training during a 10-day hands-on training
provided by the compost equipment manufacturer. The facility operator is onsite during composting
operations or available by phone. Operator certification(s) is kept with the facility records.
The final product is classified as Grade A compost, meeting the requirements of 15A NCAC 13B
.1407. To meet this classification, every six months the finished compost product is analyzed for the
metals listed in 40 CFR 503.13(b)(3) and fecal coliform per 40 CFR 503.32(a)(3). Composite
samples are submitted for laboratory analysis by collecting 1-2 quarts of a representative sample
(taken from 8-10 locations) in a sealable plastic bag. For reference, laboratory analysis performed
on finished compost in 2021 and 2022 is provided in Appendix C.
2 Vector Attraction Reduction (VAR). Temperature above 104 degrees F (40 degrees Celsius) for 14 days or
longer and the average temperature for that time shall be higher than 113 degrees F (45 degrees Celsius).

Exhibit 2. Compost Process Diagram
3.3 STORMWATER AND LEACHATE MANAGEMENT
The in -vessel compost equipment, mixing bunker, and compost curing bunkers are under roof, not
exposed to precipitation. The entire compost facility is located on a concrete pad (dimensions
roughly 80 by 90-feet) and the pad is slightly sloped towards the center to capture any stormwater
runoff from the roofs and exposed concrete pad. The pad is elevated above the surrounding terrain
so no stormwater run-on occurs. The stormwater drains into a recessed trench drain with removable
slotted grating. The drain is designed to handle up to 3,243 gallons per minute of flow. Stormwater
from the trench drain discharges into a stormwater swale located outside the eastern side of the
concrete pad. This swale conveys stormwater to an existing stormwater pond located on the Landfill
property.
The feedstock storage and mixing bunkers are potential sources of leachate. These bunkers are
under a roof so leachate would be from the feedstock itself or from added process liquids. To
minimize leachate from the mixing of the feedstock food and vegetable and fruit produce waste, the
mixing bunker is lined with double -ground yard waste to absorb the bulk of free liquids. The mixing
bunker is bordered on three sides by stackable concrete blocks to prevent free liquids from exiting
the mixing area.

4.0 OPERATION PLAN
Operation Plan is included as Appendix B.
5.0 ODOR CONTROL PLAN
An Odor Control Plan is not regulatory required for a small Type 3 compost facility. However, odors
will be controlled by using the in -vessel composting system and maintaining a manageable amount
of putrescible compost feedstock at the facility.
6.0 FINANCIAL ASSURANCE
The facility is exempt from having financial assurance, since the compost facility is owned and
operated by a local government.

2.0 COMPOST OPERATION LOCATION
The compost facility is located within the New Hanover County Landfill property, east of Cell 4B,
roughly 400 feet north of our future convenience site (will be operational in September 2023), and
roughly 450 feet south of the leachate treatment lagoon. The portion of the Landfill property that
contains the compost facility is roughly 80 feet by 90 feet.
The Landfill is a permitted and operational solid waste management facility, operating under North
Carolina Department of Environmental Quality (NCDEQ) Division of Waste Management (DWM), Solid
Waste Section (SWS) facility permit number 6504. The physical address for the Landfill is 5210 U.S.
Highway 421 North, Wilmington, North Carolina 28401.
2.1 SITE SECURITY AND ACCESS CONTROL
The compost facility is located away from the areas generally accessible to the public within the
Landfill property, and either security fencing or natural woodlands and wetlands border the property.
The Landfill entrance/exit main gate is locked between the hours of 5:00 p.m. and 6:30 a.m. on
weekdays; and from 12:00 p.m. on Saturday until 6:30 a.m. on Monday. Security cameras at the
Landfill's main gate record traffic in and out of the Landfill.
3.0 COMPOST OPERATION DESCRIPTION
The process for composting is in -vessel method. This method has the benefit minimizing leachate
and odors generation during the composting process, decreasing the time needed to attain Process
to Further Reduce Pathogens (PFRP)1, and uses a smaller footprint than other methods.
Compost feedstock collection vehicles enter the
New Hanover County Landfill where they are
weighed using the Landfill's entrance scales and
assessed for contamination. The Landfill is
selective as to the type and source of the
feedstock. Once accepted, the collection vehicle
is directed to the compost facility to unload. The
material again is assessed for contamination
during the unloading. Feedstock will be from
select sources providing the compost in -vessel
system prescribed composition of 500 pounds of
food and vegetable and fruit produce waste mixed
with approximately 800 pounds of ground yard
waste and woody material.
FOOD WASTE
COMPOSTING AREA
Place small amounts of food waste in the plastic
food
food waste barrels provided. For larger amounts,
dump food waste directly into the mixing pit.

'
Do not touch or limb in, on, or around
`
composting equipment.
When adequate amounts of feedstock are available, feedstocks are coarse blended within the
mixing bunker with the use of a skid steer with a spilt bucket attachment. The coarse blending allows
the dryer feedstock to absorb the free liquids typically found in the food and vegetable and fruit
1 Process to Further Reduce Pathogens (PFRP). Maintaining a minimal temperature of 131 degrees F (55
degrees Celsius) for at least three days.

produce waste. Once blended, the feedstock is transferred
to the mixer and allowed to dwell until the desired
consistency is met. In many cases, the operator will add a
drying/bulking agent (ground yard debris) to the mixer to
reduce total moisture in the mix. The mix is checked regularly
using the hand squeeze method until the batch is ready for
loading. Once the batch is ready for loading, the operator will
start composter rotation, in -feed auger, and in -feed conveyor.
Once all systems are functioning, the operator will raise the
mixer feed gate to the desired height and begin discharging
the batch onto the feed conveyor. The operator will visually
monitor the material flow on the feed conveyor to detect and
remove obvious contaminants, such as plastic bags, large
sticks, pieces of gravel, etc.
The feed conveyor empties onto the feed auger, which forces Mixing Bunker
the material directly into the composter. If any foreign
objects jam the auger, it will automatically reverse itself up to six times before signaling an alarm to
the system. This alarm stops the feed conveyor and must be acknowledged and rectified by the
operator prior to continuing feeding operations.
Once the raw feedstock is in the
composter, the operator repeats
the above steps until the
composter is full. The composter
has roughly 60 cubic yards of
capacity, so it may take several
days to completely fill the vessel.
In between feeding operations, the
operator will lower the mixer metal
cover to protect the material from
rainwater as well as reduce vectors
ING -zhw and minimize any potential odors.
Mixer. In -Feed Conveyor/Auger & Composter While the in -vessel composter is in
operation, the operator shall
monitor and record the temperatures within the vessel. To achieve PFRP, the compost is treated in -
vessel. The operator monitors composter turning, temperature, and airflow to attain a continues
minimum temperature of 1310 F for at least three (3) days. Once the temperature and duration
criteria is achieved, the compost will have achieved PFRP and will be placed in bunkers to begin the
Vector Attractant Reduction (VAR)2 phase. The operator can then add additional feedstock to the
2 Vector Attraction Reduction (VAR). .

composter. Prior to adding additional
material to the composter, the operator
engages the trommel screen and discharge
conveyor. The incoming (raw) feedstock
displaces the uncured compost out from the
vessel and onto the trommel screen.
The trommel screen is designed to separate
large sticks, rocks, and other undesirable
material from the uncured compost. The
screened uncured compost discharges onto
the stacking conveyor, which transfers the
material to an area on the pad near the
curing bunkers.
The screened, uncured compost is then
moved into one of the curing bunkers to
begin the VAR (Vector Attractant Reduction)
phase. Once fourteen (14) consecutive days
of temperatures above 1040F (with an
average temperature of 1130F) have been
attained, the compost will have achieved
VAR and will be stored in bunkers for at least
2 weeks for additional curing. Piles will be
turned weekly to ensure adequate oxygen is
present in the mix. Progress will be recorded
on both paper forms as well as on signage
mounted at the entrance to each bunker.

Equipment maintenance consists of regular lubrication of motors, drive wheels, and drive chains as
outlined in the owner's manual. Four different types of lubricants/oils are stocked on -site in a
storage building.
ABC -rated fire extinguishers are mounted on building posts near the control panel, trommel screen,
and mixing and curing bunkers. These extinguishers are regularly inspected and maintained by a
third party. Electrical disconnects are also installed for each subsystem as well as a main facility
disconnect.
3.2 COMPOST FEEDSTOCK
Approximately 25 tons per week (1,300 tons/year) or 1,400 cubic yards of the following materials
are expected to be processed into Class A compost at the facility:
• Ground yard waste and land clearing debris
• Ground unpainted/untreated lumber and pallets
• Pre- and post -consumer food waste, including meat and poultry products and spent
brewery waste
• Land clearing (inert) debris
• Vegetable and fruit produce waste
• Soiled animal bedding and animal dung/manure
• Animal carcasses
Feedstock will be from select sources providing the
composting in -vessel system prescribed composition of 500
pounds of food and vegetable and fruit produce waste mixed
with approximately 800 pounds of ground yard waste and
woody material. The feedstock should be assessed by the
operator before unloading. Deliveries and operator
assessment should be recorded in the delivery log in
Appendix B.
Mixing Bunker - Putrescible Waste
Delivery Location
Ground wood and yard waste feedstock will
be maintained in separate piles in an area
adjacent to the compost facility within
concrete bunkers. Putrescible wastes, such
as pre and post -consumer food, food

processing, and produce wastes will be temporarily stored in the mixing bunker with dry ground yard
waste before the blending process. Once blending is completed, the feedstock will be transferred to
the mixer/in-vessel composter. Dry ground yard waste is added to the mixing bunker to soak up any
liquids from putrescible wastes.
3.3 TEMPERATURE CONTROL
In -vessel composter temperature is controlled by four variables: moisture content of the feedstock,
feedstock formula, rotation (turning), and air flow. Moisture content is measured for a selected
feedstock by use of on -site drying ovens and desiccants to calculate percent moisture content, with a
target of 45-50% moisture content.
Moisture content is managed using additional drying agents (such as ground yard debris or ground
wood waste) in the mixer (in the case of material that has a high moisture content), or by adding
water or additional food waste if the moisture content is too low.
The in -vessel composter accomplishes turning automatically, with rotation speed controlled by the
operator. The system can be programmed to turn the composter automatically at pre-set times and
intervals by simple entries into the control panel.
Airflow is accomplished by a negative -draft fan that pulls outside air over the raw compost and vents
the stale air and humidity outside of the vessel. This serves to introduce fresh oxygen into the
process to maintain a healthy environment for beneficial bacteria. The fan is controlled by the
operator, but can be set to run automatically through operator inputs into the control panel.
Temperatures are displayed real-time on the control panel. Manual temperature readings can also
be taken (using a thermocouple probe) through ports built into the composter. Regular temperature
readings (a minimum of daily) are recorded on forms available to the operator and kept on file for
each batch.
3.4 MONITORING
Temperatures will be measured and recorded daily during the PFRP process (while materials are in -
vessel) until the batch has maintained 131OF or greater for at least three (3) days before being
moved to the curing bunkers. While the material is in -vessel, temperatures either are taken via
access ports using a 48-inch temperature probe (fully inserted into the vessel) or are provided on a
continuous basis electronically on available touch -screen systems. Temperatures will be recorded on
a daily basis using the log provided in Appendix B.
Moisture content can be checked at three stages during the composting process: after blending,
after exiting the in -vessel system, and after the material has cured for 7 days. Moisture content can
be assessed using the landfill's desiccator or drying oven, available in the on -site laboratory.
Moisture content can also be checked in the field using a standard paint -filter test, though this
method is not the preferred method.
To meet the criteria for vector attraction reduction (VAR), the curing piles will be maintained at a
minimum temperature of 1040F (average temperature of 1130F) for 14 days. During this time,
temperatures will be taken on a daily basis and recorded using a 48-inch temperature probe
inserted at least 24-inches into the pile, with a preferred depth of 24 to 36-inches. Due to the
Operation Plan for an In -Vessel
Composting System www.scsenQineers.com
Page 7

compact nature of the curing bunkers and small size of each batch, temperatures will be taken from
two areas within each curing pile, 48-inches apart.
3.5 COMPOST PRODUCT TESTING
The final product is classified as Grade A compost for public distribution. To meet this designation,
the finished compost product is sampled and analyzed by a laboratory for the metals listed in 40 CFR
503.13(b)(3) and for fecal coliform twice a year. The metals listed and their limits on a dry weight
basis in milligrams per kilogram (mg/kg) is Arsenic (41), Cadmium (39), Copper (1500), Lead (300),
Nickel (420), Selenium (100), and zinc (2800). The compost fecal coliform limit listed in 40 CFR
503.32(a)(3) is less than 1000 Most Probable Number per gram of total solids dry weight.
The sample collected for metals and fecal coliform analysis shall be a representative composite of
the compost produced, comprised of at least three individual samples of equal volume. The metals
analysis composite sample shall be accumulated over a six-month period while fecal coliform is
sampled within the period required by the testing method. The samples shall be collected from the
interior of compost piles, two to six -feet from a piles outer surface. Approved analytical testing
methods are provided in EPA publication SW-846 (Test Methods for Evaluating Solid Waste:
Physical/Chemical Methods Compendium), the U.S. Department of Agriculture/U.S. Composting
Council publication "Test Methods for the Examination of Composting and Compost", or other
methods approved by the North Carolina Department of Environmental Quality Division of Waste
Management.
4.0 STAFFING AND TRAINING
Effective November 2019, the compost facility is required to have an operator, supervisor, or
manager trained in compost operations via a North Carolina Department of Environmental Quality
(NCDEQ) Division of Waste Management (DWM) approved course. Approved courses and
certifications are provided by the Compost Research & Education Foundation, Solid Waste
Association of North America (SWANA), and US Compost Council Certification Commission.
In addition to the certified operator, another employee shall been cross -trained as a backup. The
operator shall be onsite during composting operations or available by phone. Operator
certification(s) shall be kept with the facility records.
On at least an annual basis, compost facility operator and staff shall review the contents of the
Operation Plan and permit documents. This review shall be documented and kept with the facility
records.
5.0 RECORD KEEPING AND REPORTING
The following records shall be available for inspection by North Carolina Department of
Environmental Quality (NCDEQ) Division of Waste Management (DWM) personnel during the facility's
normal business hours and shall be sent to the DWM upon request:
1. daily operational records that include temperature data (length of the composting period)
and quantity of material processed;
2. analytical results of compost testing;

6. operator training records and certifications; and
7. fires that occur at the compost facility shall be reported to the DWM orally within 24 hours
of the incident and in writing within 15 days of the incident.
These records shall be maintain by the Facility owner/operator for no less than five years.
An annual report for the period July 1 to June 30 shall be submitted to the DWM by August 1 of each
year and shall contain: (1) the facility name, address, and permit number; (2) the total quantity in
tons, with sludge values expressed in dry weight, and the type of waste received at the facility during
the year covered by the report, including tons of waste received from local governments of origin; (3)
the total quantity in tons of compost produced at the facility during the year covered by the report;
(4) the total quantity in tons of compost removed for use or disposal from the facility during the year
covered by the report; (5) monthly temperature monitoring to support section .1406 of the NC
Administrative Code Title 15A Subchapter 13B (15A NCAC 13B .1406); and (6) the results of
analytical testing required by 15A NCAC 13B .1407.
6.0 STORMWATER AND LEACHATE MANAGEMENT
6.1 STORMWATER MANAGEMENT
The in -vessel compost equipment, feedstock mixing
bunker, and compost VAR bunkers are under roof, not
exposed to precipitation. The entire compost facility is
located on a concrete pad (dimensions roughly 80 by 90-
feet) and the pad is slightly sloped towards the center to
capture any stormwater runoff from the roofs and
exposed concrete pad. The stormwater drains into a
recessed trench drain with removable slotted grating.
The drain is designed to handle up to 3,243 gallons per
minute of flow. Stormwater from the trench drain
discharges into a stormwater swale located outside the
eastern side of the concrete pad. Concrete Pad with Recessed Trench
The trench drain and grate shall be inspected by facility Drain
staff periodically for any clogging potential and if a
potential exists, the trench drain and grate should be cleaned. Identified potential stormwater
contaminants from the facility is the accumulation of dirt and debris on the exposed concrete pad.
To minimize this, the concrete pad should be swept regularly to remove any dirt and debris.
6.2 LEACHATE MANAGEMENT
The feedstock mixing bunker is a potential source of leachate. This bunker is under a roof so
leachate would be from the feedstock itself or from added process liquids. To minimize leachate
from the mixing of the food and vegetable and fruit produce waste, the mixing bunker should be
Operation Plan for an In -Vessel
Composting System www.scsenQineers.com
Page 9

lined with double -ground yard waste to absorb the bulk of free liquids. The mixing bunker is
bordered on three sides by stackable concrete blocks to prevent free liquids from exiting the mixing
area. The garage door to the mixing bunker will be closed during periods of inactivity as well as
during heavy rainfall events. In the event leachate leaves the confines of the bunker, it should be
collected and transported to the onsite Ieachate treatment lagoon.
Other possible sources of Ieachate and actions to be taken to minimize include:
Mechanical mixer is sealed to prevent any liquids from leaving the mixer and the metal
top should be lowered over the mixer feed opening when loading is not occurring.
The composter is sealed to prevent any free liquids from exiting the unit. Any Ieachate
within the unit is evaporated during the PFRP process and removed from the vessel by
means of the equipment negative draft fan. In the unlikely event of any Ieachate building
up within the unit, several sealed access ports can be removed to drain free liquids into a
container for transport to the onsite Ieachate treatment lagoon.
7.0 CONTINGENCY PLAN
7.1 WEATHER -RELATED CONTINGENCIES
In the event of extreme weather conditions (such as heavy rainfall or electrical storms), operations at
the compost facility will be curtailed until conditions improve. Prior to curtailment, all putrescible
feedstock will be covered with weighted tarps and equipment shut down. If the event of an extended
period of heavy rainfall, all putrescible waste will be removed from the site and disposed of within
the Landfill.
If severe weather is predicted (such as hurricanes or tornados), all operations will cease and
deliveries of feedstock will be canceled. Any putrescible feedstock within storage areas/bunkers will
be removed and disposed of within the Landfill. Mobile equipment will be parked in sheltered areas
and shut down. Compost equipment will be shut down via the control panel and de -energized using
the manual electrical disconnects.
7.2 EQUIPMENT FAILURE -RELATED CONTINGENCIES
In the event of equipment failure, the operator will determine whether the affected system affects
continuation of operations while repair/replacements are scheduled and performed. For example, if
the stacking conveyor's belt is torn, the operator may elect to continue mixing/blending operations.
Mechanical failures with the skid steer do not affect the ability of the operator to continue utilizing
the in -vessel system normally, and would not affect those operations. Replacement parts for the in -
vessel composter are generally available within 2-5 business days, and a County employee that is a
full-time mechanic is on staff and available to assist with troubleshooting and minor repairs. The
composter vendor is also able to troubleshoot the system remotely and provide advice and feedback.
In the event of a prolonged period of downtime, deliveries of putrescible feedstock will be postponed
and any stored material will be transferred to the Landfill for disposal.

3. Analysis
The samples were analyzed using Waters Acquity UPLC equipped with Xevo TQ MS (LC/MS/
MS "Kili").
For solid chemical material (SCM) samples, a 1 - 2g nominal aliquot was weighed and spiked
with Extraction Standard (ES). The sample was then sonicated and centrifuged.
Cleanup procedures were performed on the supernatant and then extracted via SPE. Each final
sample extract was transferred to an autosampler vial and spiked with Injection Standard (IS),
prior to analysis.
4. Calibration
In the initial calibration the reported analytes exhibited R A 2 of >_ 0.99. The reported analytes in
the calibration standards, continuing calibration (concal) and Initial Calibration Verification (ICV)
met the 30% accuracy criterion for native analytes.

:1 General Reporting Notes — Data Qualifiers
E N I HALM'
The following are general reporting notes that are applicable to all Enthalpy Analytical, LLC -
Wilmington, NC data reports, unless specifically noted otherwise.
General Data Qualifiers
• B — The analyte was found in the method blank, at a concentration that was at least 10% of the
concentration in the sample.
• Cxx — Two or more congeners co -elute. In EDDs, C denotes the lowest IUPAC congener in a co -
elution group and additional co-eluters for the group (`xx') are shown with the number of the
lowest IUPAC co-eluter.
• E — The reported concentration exceeds the calibration range (upper point of the calibration
curve). For HRMS data, this condition does not imply additional measurement uncertainty. For
LC-MS/MS data, these values should be considered as having measurement uncertainty higher
than values within the calibration range.
• EDL — Estimated Detection Level. Specific to Dioxin/Furan tests and equivalent to MDL
• EMPC — Estimated Maximum Possible Concentration Specific to Dioxin/Furan tests to indicate
the signal/noise ratio wass not sufficient for peak identification (the determined ion -abundance
ratio was outside the allowed theoretical range), or where there was a co -eluting interference.
Indicates that a peak was identified but did not meet the method specified ion -abundance ratio.
• IR — The ion ratio between the primary and secondary ions was observed to be outside the
method criteria therefore the actual analyte concentration cannot be accurately determined as
defined by DoD QSM Table B-15.
• J —The analyte has a concentration below the minimum calibration level (LOQ value) but greater
than the LOD. These values should be considered as having measurement uncertainty higher than
values within the calibration range
• L - Indicates that an analyte has a concentration below the Minimum Detection Limit (MDL).
The reported concentration is not recommended for regulatory use as the analyte signal may have
a signal-to-noise ratio less than the criteria deemed necessary to be considered a detected analyte.
• LOD — Limit of Detection: For reports conforming to the DOD ELAP QSM, this is the QSM-
defined LOD. For reports conforming to TNI requirements (but not DOD ELAP QSM
requirements), this value is the minimum detection limit (MDL). The LOD is adjusted for sample
weight or volume.
• LOQ — Limit of Quantiation: For reports conforming to the DOD FLAP QSM, this is the QSM-
defined LOQ. For reports conforming to TNI requirements (but not DOD ELAP QSM
requirements), this value is the reporting limit (RL). The LOD is adjusted for sample weight or
volume.
• <LODQ — Analyte was not found at a concentration high enough to be reported as detected. It is
reported as less than the LOD, and the LOD is given in the parentheses.

General Reporting Notes — data Qualifiers
LN I HALPY
• ND — Indicates a non -detect.
• NR — Indicates a value that is not reportable due to issues observed in sample preparation or
analysis.
• PR— The associated congener(s) is(are) poorly resolved.
• QI — Indicates the presence of a quantitative interference.
• RL — Reporting Limit. Lowest reportable value. The level is higher than the MDL.
• SI — Denotes "Single Ion Mode" and is utilized for PCBs where the secondary ion trace has a
significantly elevated noise level due to background PFK. Responses for such peaks are
calculated using an EMPC approach based solely on the primary ion area(s) and may be
considered estimates.
• U — The analyte was not detected.
• V / Q — The labeled standard recovery is not within method control limits.
• X — Results from re-injection/repeat/second-column analysis.
Lab Identifiers/ Data Attributes
• AR — Indicates use of the archived portion of the sample extract.
• CU — Indicates a sample that required additional clean-up prior to HRMS injection/processing.
• D — Dilution Data. Result was obtained from the analysis of a dilution. The number that follows
the "D" indicates the dilution factor.
• DE — Indicates a dilution performed with the addition of ES (Extraction Standard) solution.
• DUP — Designation for a duplicate sample.
• MS — Designation for a matrix spike.
• MSD — Designation for a matrix spike duplicate.
• RJ — Indicates a reinjection of the sample extract.
• S — Indicates a sample split. The number that follows the "S" indicates the split factor.
• R — Indicates a re -extraction of the sample.

3. Analysis
The sample was analyzed using Waters Acquity UPLC equipped with Xevo TQ MS (LC/MS/MS
"Aragorn").
For solid chemical material (SCM) samples, a 1-2g nominal aliquot was weighed and spiked with
Extraction Standard (ES). The sample was then sonicated and centrifuged.
Cleanup procedures were performed on the supernatant and then extracted via SPE. Each final
sample extract was transferred to an autosampler vial and spiked with 150 pL of Injection
Standard (IS), prior to analysis.
4. Calibration
In the initial calibration, the reported analytes exhibited R"2 of >_ 0.99. The reported analytes in
the calibration standards, continuing calibration (concal) and Initial Calibration Verification (ICV)
met the 30% accuracy criterion for native analytes. _.

Client ID. 2022-23305
5. QC Notes
The QC sample analyses passed all method criteria.
The samples were extracted within the 28-day from collection holding time and analyzed within
the 28-day from extraction to analysis holding time required by the method.
Sample received above 6 °C, client notified in order acknowledgement documentation.
6. Reporting Notes
Sample was initially screened by direct inject analysis to determine extraction mass for analysis.
One gram of sample was vortexed in methanol. An aliquot of the methanol solution was fortified
with ES and IS then conditioned with a methanol:water solution prior to injection.
The results presented in this report are representative of the samples as provided to the
laboratory.
Solid results are reported on a dry weight basis. To achieve nominal 1-2g sample aliquot, a
percent solid analysis was performed to determine dry weight. "As Is" results are available upon
request.
These analyses met the requirements of the TNI Standard. Any deviations from the
requirements of the reference method or TNI Standard have been stated above.
Enthalpy Analytical, LLC in Wilmington NC is accredited by the Louisiana Department of
Environmental Quality to the 2009 TNI Standard under certificate number 05075.

aak 4— General Reporting Notes — Data Qualifiers
LN 1'I- ALI'Y
The following are general reporting notes that are applicable to all Enthalpy Analytical, LLC -
Wilmington, NC data reports, unless specifically noted otherwise.
General Data Qualifiers
* B - The analyte was found in the method blank, at a concentration that was at least i 01,io of the
amount in the sample.
• Cxx - Two or more congeners co -elute. In EDDs, C denotes the lowest IUPAC congener in a co -
elution group and additional co-eluters for the group (`xx') are shown with the number- of the
lowest IUPAC co-eluter.
• E - The reported concentration exceeds the calibration range (upper point of the calibration
curve). For HRMS data, this condition does not imply additional measurement uncertainty. For
LC-MS!MS data, these values should be considered as having measurement uncertainty higher
than values within the calibration range.
• EDL - Estimated Detection Level: The EDL is unique to isotope dilution methods and reflects
the conditions of analysis at the time of analysis, including the equipment used. Where the MDL
is a static value, the EDL is a dynamic value.
• EMPC - Estimated Maximum Possible Concentration: EMPC is specific to Dioxin/Furan tests to
indicate the determined ion -abundance ratio was outside the allowed theoretical range (usually
due to being near the detection limit, although it can very rarely be caused by a co -eluting
interference). The EMPC concentration is adjusted to reflect the value at the theoretical ion -
abundance ratio.
• IR - The ion ratio between the primary and secondary ions was observed to be outside the
method criteria. The analyte concentration may be inaccurate due to interference.
• J - The analyte has a concentration below the minimum calibration level (LOQ value) but greater
than the LOD. These values should be considered as having measurement uncertainty higher than
values within the calibration range
• L - Indicates that an analyte has a concentration below the Minimum Detection Limit (MDL).
The reported concentration is not recommended for regulatory use as the analyte signal may have
a signal-to-noise ratio less than the criteria deemed necessary to be considered a detected analyte.
• LOD - Limit of Detection: For reports conforming to the DOD ELAP QSM, this is the QSM-
defined LOD. For reports conforming to TNI requirements (but not DOD ELAP QSM
requirements), this value is the minimum detection limit (MDL). The LOD is adjusted for sample
weight or volume.
• LOQ - Limit of Quantitation: For reports conforming to the DOD ELAP QSM, this is the QSM-
defined LOQ. For reports conforming to TNI requirements (but not DOD ELAP QSM
requirements), this value is the reporting limit (RL). The LOQ is adjusted for sample weight or
volume.

"! 1 General Reporting Motes — Data Qualifiers
N fl-IALVY
• <LODQ — Analyte was not found at a concentration high enough to be reported as detected. It is
reported as less than the LOD, and the LOD is given in the parentheses.
• <LOQO — Anaiyte was not found at a concentration high enough to be reported as above the
QSM-defined LOQ or TNI defined Reporting Limit. It is reported as less than the LOQ, and the
LOQ is given in the parentheses.
• ND — Indicates a non -detect.
• NR — Indicates a value that is not reportable due to issues observed in sample preparation or
analysis.
• PR — The associated congener(s) is(are) poorly resolved.
• QI — Indicates the presence of a quantitative interference.
• RL — Reporting Limit. Lowest reportable value. The level is higher than the MDL.
• SI — Denotes "Single Ion Mode" and is utilized for PCBs where the secondary ion trace has a
significantly elevated noise level due to background PFK. Responses for such peaks are
calculated using an EMPC approach based solely on the primary ion area(s) and may be
considered estimates.
• U — The analyte was not detected.
• V / Q — The labeled standard recovery is not within method control limits.
• X — Indicates the result is from re-injection/repeat/second-column analysis.
Lab Identifiers/ Data Attributes
• AR — Indicates use of the archived portion of the sample extract.
• CU — Indicates a sample that required additional clean-up prior to HRMS injection/processing.
• D — Dilution Data. Result was obtained from the analysis of a dilution. The number that follows
the "D" indicates the dilution factor.
• DE — Indicates a dilution performed with the addition of ES (Extraction Standard) solution.
• DUP — Designation for a duplicate sample.
• MS — Designation for a matrix spike.
• MSD — Designation for a matrix spike duplicate.
• R — Indicates a re -extraction of the sample.
• RJ — Indicates a reinjection of the sample extract.
