The revised Environmental Control Monitoring Plan (ECMP; Revision 2) for the Industrial Landfill No.1 (INDUS-
1812), located in Catawba County, North Carolina, is provided for review and approval, and proposed to
supersede the previously revised and approved ECMP from December 2020.
This ECMP has been updated to incorporate the Phase 2, Cell 5 landfill underdrain sample (MSS-LF-UD1) and
include the leachate basin leak detection monitoring location (MSS -LB -LDS). The underdrain was an approved
design modification for the construction of Cell 5. Construction of the underdrain was completed in October 2021
and the underdrain has been operational since. The leachate basin leak detection monitoring location was
incidentally missed in previous versions. The leachate basin is still under construction; completion of construction
and start of operations is anticipated to occur in mid-2022.

Environmental Controls Monitoring Plan
1.0 Introduction
This Environmental Controls Monitoring Plan (Plan) for the Duke Energy Marshall Steam Station
(Marshall/Plant/Site) establishes locations and procedures for monitoring early detection of solid waste
or leachate potentially released to the environment from the Industrial Landfill No. 1 — Phases 1 and 2
(landfill/ILF) and leachate impoundment (leachate basin).
The landfill is situated partially within an area that was formerly used for the storage or disposal of coal
combustion residuals (CCR).
The landfill is designed and constructed in accordance with North Carolina General Statute (NCGS)
130A 295.4 for Combustion Products Landfills. This Plan is intended to satisfy the requirements of a
groundwater monitoring plan required by North Carolina Administrative Code Title 15A Subchapter 13B
(NCAC 15A 13B) .0504(1)(g)(iv) (proposed .0504 (c)(8)(D)) in accordance with NCGS 130A 295.4(c)
which states in part "compliance with performance of the landfill to prevent releases of waste to the
environment may be determined based on leakage rate rather than monitoring well data". Additionally,
groundwater monitoring, required by the US Environmental Protection Agency (USEPA) Title 40 Code
of Federal Regulations Part 257 Subpart D (CCR Rule), is in accordance with 40 CFR §257.91(d)
which states "the owner of operator of multiple CCR units may install a multiunit groundwater
monitoring system instead of separate groundwater monitoring systems for each CCR unit". The landfill
is part of a multiunit system with the ash basin.
The leachate basin is designed and constructed in accordance with NCAC 15A 13B .1680. This Plan is
intended to satisfy the requirements of a groundwater monitoring system required by NCAC 15A 13B
.1680(e)(6) which states in part that "an alternative monitoring system approved by the Division" can be
used to satisfy the monitoring requirements.
Prior to completion of landfill closure, this Plan will be evaluated and North Carolina Department of
Environmental Quality (NCDEQ) Division of Waste Management (Division) will be consulted to
determine if this Plan should be revised for post closure monitoring of landfill performance.
1.1 Site Description
The approximate 67.1-acre landfill (Phase 1 and 2) is located north of the Marshall power
block and generally bounded by the property line to the north, vacant land and closed
asbestos and debris landfill areas (1804-INDUS) to the east, and CCR Structural Fill CCB0031
(previously known as the PV Structural Fill), the MAR-145 industrial stormwater pond, and
historic ash basin to the south and west (Drawing 1). The Division issued the initial ILF Permit
to Operate on March 7, 2011. Phase 1 is constructed over the CCR Structural Fill CCB0072
(Landfill Phase I Subgrade). Phase 2 of the landfill is immediately south of Phase 1. Phase 1,
Phase 2, and Structural Fill CCB0072 are situated adjacent to and partially over an upstream
area of the historic ash basin waste boundary.
The leachate basin is located south of the ILF bounded by the historic ash basin on the north,
east, and south and the CCR Structural Fill CCB0031 on the west (Drawing 2). The leachate
is conveyed from the landfill to the leachate basin via a forcemain piping network. The
leachate basin discharges to the Lined Retention Basin (LRB) where it is comingled with other
Marshall wastewater for treatment (Drawing 2). The LRB discharges through a permitted
National Pollutant Discharge Elimination System (NPDES) outfall.

Industrial Landfill No. 1 1812-INDUS Revision 2, December 13, 2021
Environmental Controls Monitoring Plan
The landfill and leachate basin engineered base liners include a leak detection system (LDS)
that monitors the integrity of the primary flexible membrane liner. A network of drainage
features manage stormwater from the landfill and adjacent area, which is routed to a permitted
outfall. No stormwater from the landfill area flows off the Site property or enters a surface
water prior to passing through a permitted outfall.
The historic ash basin, which partially underlies the landfill and is adjacent to the leachate
basin, received CCR via sluice lines beginning in 1965 until early 2019. In 1984, Marshall
converted from wet to dry fly ash handing. In 2019 bottom ash was converted from wet to dry
handling and all ash sluicing ceased. Duke Energy is authorized to discharge wastewater from
the ash basin to Lake Norman (Outfall 002) in accordance with NPDES Permit NC0004987.
Groundwater from beneath and in the vicinity of the ash basin and leachate basin is sampled
and analyzed according to the NCDEQ approved monitoring plan which meets the
requirements of the Coal Ash Management Act (CAMA).
The landfill and ash basin are monitored together, as a multiunit unit in accordance with the
requirements of 40 CFR 257.91(d). CCR Rule groundwater monitoring networks are certified
by a qualified professional engineer in accordance with 40 CFR 257.91(f) and subject to
additional modifications if wells are abandoned due to construction or ash basin closure
activities. Groundwater is sampled and analyzed semi-annually according to the requirements
of 40 CFR 257.93.
The CAMA and CCR Rule groundwater monitoring programs include routine monitoring and
reporting.
The majority of waste intended for placement throughout the life of the landfill consists of CCR,
predominantly fly ash and bottom ash. The approved waste stream can be found in the
Operations Plan.
1.2 Site Geology and Hydrogeology
The groundwater system in the natural materials (shallow/deep/bedrock) at Marshall is
consistent with the regolith-fractured rock system and is characterized as an unconfined,
interconnected aquifer system indicative of the Piedmont Physiographic Province in which the
site is contained. The groundwater system at the site is divided into the following three layers
to distinguish the interconnected groundwater system: the shallow flow zone, deep (transition
zone) flow zone, and the bedrock (competent bedrock) flow zone.
The ash basin, landfill, leachate basin, closed historic landfills, and CCR Structural Fills are
contained within a former perennial stream valley (flow compartment) (Drawing 1).
Groundwater within the flow compartment is a flow -through system. Groundwater enters the
system from the upgradient end near the landfill and flows laterally through the middle regions
and downward near the dam, or downgradient end. Groundwater divides are located west and
north of the landfill, concurrent with topographic ridges along Sherrills Ford Road to the west
and Island Point Road to the north. The topographically controlled flow direction provides
natural hydraulic control of constituent migration from the ash basin and adjacent sources
within the flow compartment.

Industrial Landfill No. 1 1812-INDUS Revision 2, December 13, 2021
Environmental Controls Monitoring Plan
A recent potentiometric surface of the uppermost aquifer created by water level values from
direct measurements obtained from the CAMA and CCR Rule monitoring networks for the
area that includes the landfill, ash basin, leachate basin, closed historic landfills, and CCR
Structural Fills is provided as Drawing 3. The primary flow path of the groundwater remains
generally northwest to southeast within the flow compartment. This recent potentiometric
surface should not be used to estimate future groundwater conditions since ash basin closure
by excavation has the potential to alter groundwater elevation and flow.
2.0 Monitoring Network
Performance of the landfill and leachate basin engineered liner systems will be evaluated for control of
releases to the environment based on the flow rate within the engineered base liner LDS (described
below). Groundwater downgradient of the landfill and leachate basin is monitored in accordance with
CAMA and the CCR Rule groundwater monitoring programs and therefore not addressed in this Plan.
Leachate is sampled from the leachate collection system upstream of the leachate basin to primarily
provide analytical data to assist in evaluating potential water quality exceedances or Response Action
Plan requirements and determine if the landfill or leachate basin performance is a contributor of
constituents in the environment.
2.1 Engineered Base Liner System Leak Detection Monitoring
2.1.1 Engineered Base Liner System Leak Detection — Monitoring (NCGS 130A
295.4(b) and NCAC 15A 13B .0602(e)(6))
Leak detection system monitoring is conducted on a routine basis as defined in the
Operations Plan. A LDS is incorporated into the design of the landfill and leachate
basin engineered base liner systems to monitor performance to prevent a release to the
environment. LDS monitoring occurs in the vicinity of each landfill sump and leachate
basin sump, identified as MSS-LF-LDS1 through MSS-LF-LDS6 and MSS -LB -LDS on
Drawing 2.
The landfill, in accordance with NCGS 130A 295.4(b), and leachate basin in accordance
with NCAC 15A 13B .1680(e)(2) are constructed with a base liner system that includes a
primary and secondary geomembrane liner. The primary and secondary liners are
separated by a geocomposite drainage layer to create a leak detection layer. The
geocomposite provides enough capacity to convey liquid that enters the leak detection
layer to a sump area (lowest elevation in an area of the liner system) where it is
collected for removal by mechanical pumping. Removal of liquid from the leak detection
layer in addition to the combination of a geosynthetic clay liner (GCL) and compacted
soil liner beneath the secondary liner reduces the potential for liquid to enter the
environment. The quantity of liquid removed from the leak detection layer is measured
and recorded.
Details and calculations for the engineered base liner systems are included in the
Engineering and Facility Plan. The presence of liquid in a leak detection layer is typical
and anticipated from but not limited to:
• water remaining in the geonet or sump from initial construction;
Page 3 of 11

Industrial Landfill No. 1 1812-INDUS Revision 2, December 13, 2021
Environmental Controls Monitoring Plan
condensed liquid accumulated after installation of the overlying primary
geomembrane, and;
• flow through defects in the primary geomembrane.
Design of the liner LDS includes defining the rate at which water entering the leak
detection layer is not typical under normal operations. The Engineering and Facility
Plan includes the method used to define an Initial Response Leakage Rate (IRLR) and
Action Leakage Rate (ALR) for the leak detection layer. The ALR represents the
maximum sustained flow rate that would be expected in the leak detection layer under
normal conditions. The IRLR is generally a fraction of the ALR and represents the initial
threshold where action would be required. The IRLR and ALR monitoring rates for the
landfill and Ieachate basin are provided below as defined in the Operations Plan.

A Response Action Plan for the landfill and Ieachate basin is included in the Operations
Plan Section 2.4.3 and the list of required actions if the IRLR or ALR is exceeded are
provided in the Operations Plan Section 2.4.4 to comply with NCGS 130A 295.4(c).
The purpose of the Response Action Plan and list of actions is to define the necessary
steps in the event liquid in the leak detection layer exceeds the IRLR and/or ALR. Leak
detection layer flow rates are monitored, recorded, and compared to the defined IRLR
and ALR.
2.1.2 Engineered Base Liner System Leak Detection - Reporting
Average monthly flow rates with comparison to leakage rates will be provided to the
Division in the semi-annual landfill Environmental Controls Monitoring Report.
Information provided in the report will consist of:
a summary of average monthly flows from each LDS sump (Drawing 2), with
comparison to the IRLR and ALR, will be provided in tabular form for the semi-annual
reporting timeframe (through the month when sampling defined in this Plan occurs)
and;
if exceedances of the IRLR and/or ALR are identified in the reporting timeframe, a
summary of actions in accordance with the Response Action Plan will be provided.
The summary will generally include:
o date of the Division notification
o cause of exceedance (if known or summary of evaluation efforts to date)
o corrective action implemented or planned (if applicable)

2.2 Water Quality
2.2.1 Water Quality Monitoring
2. 2.1.1 Surface Water — Monitoring (NCAC 15A 13B .0602)
Surface water quality monitoring is not required for Phases 1 and 2 of the landfill.
Surface water (non -contact stormwater) will be directed via channels around the
perimeter of the landfill to a NPDES wastewater unit or permitted Stormwater Outfall.
This Plan will be reviewed if the path of stormwater leaving the landfill area will be
altered or permit status for receiving unit(s) will change. The Division will be consulted to
determine if surface water quality monitoring requirements should be revised for
monitoring of stormwater leaving the landfill area.
2.2.1.2 Underdrain Outlet — Monitoring
Underdrain outlet water samples are collected and analyzed on a semi-annual basis
from a sample location designated as MSS-LF-UD1. The underdrain is located in the
upper southwest corner of Phase 2. The underdrain outlet sample location is shown on
Drawing 2.
Underdrain outlet water samples are analyzed for the constituents summarized on Table
1.
2.2.2 Water Quality Reporting
2.2.2.1 Surface Water — Reporting
Surface water reporting is currently not required for the landfill (see Section 2.2.1). This
Plan will be revised to include the following general language in this section, as
applicable, if surface water monitoring becomes required in Section 2.2.1:
• surface water analytical results will be compared to respective Classifications and
Water Quality Standards Applicable to Surface Waters and Wetlands of North
Carolina as defined in Title 15A NCAC Subchapter 02B (02B Standards)
surface water results will be provided to the Division in the semi-annual landfill
Environmental Controls Monitoring Report. Information provided in the report will
consist of:
o a copy of the laboratory report(s);
o a copy of the sampling log(s);
o a table of analytical results and field parameters that will include:
■ results reported in micrograms per liter (ug/L), except for field parameters;
Page 5 of 11

Industrial Landfill No. 1 1812-INDUS Revision 2, December 13, 2021
Environmental Controls Monitoring Plan
■ laboratory method detection limits, and;
■ comparison to appropriate 02B Standards with exceedances shown in bold.
2.2.2.2 Underdrain Outlet — Reportinq
Underdrain outlet analytical results will not be compared to any water quality standards
for flow that:
• outlets inside the boundary of a NPDES permitted wastewater unit and/or;
• passes through a NPDES permitted outfall before entering surface water.
Underdrain outlet sample MSS-LF-UD1 is within the NPDES permitted
wastewater unit and is passes through a NPDES permitted outfall downstream,
therefore, sample results from the underdrain outlet will not be compared to any
water quality standards.
Underdrain outlet analytical results will be provided to the Division in the semi-annual
landfill Environmental Controls Monitoring Report. Information provided in the report will
consist of:
• a copy of the laboratory report(s);
• a copy of the sampling log(s);
a table of analytical results and field parameters that will include: analytical results
reported in micrograms per liter (pg/L), except for field parameters
o analytical results reported in micrograms per liter (pg/L), except for field
parameters
o laboratory method detection limits.
2.3 Leachate
2.3.1 Leachate - Monitoring
Discrete leachate samples will be collected and analyzed on a semi-annual basis from
each sump, MSS-LF-LCS1 through MSS-LF-LCS6, located in the vicinity of each
corresponding sump header. A comprehensive leachate sample will also be collected
and analyzed on a semi-annual basis from MSS-LF-LCSC, located along the force main
downstream of all six landfill cells, prior to discharging to the leachate basin.
Leachate sample locations are shown on Drawing 2.
Leachate will be analyzed for the constituents summarized on Table 1.
2.3.2 Leachate - Reporting
Leachate analytical results will not be compared to any water quality standards.

3.0 Sampling and Analysis
Leachate samples will be collected and analyzed as described in this section.
3.1 Water Quality
3.1.1 Surface Water— Sampling and Analysis
Surface water sampling and analysis is currently not required for the landfill (see
Section 2.2.1).
This Section will be revised if surface water monitoring becomes required as defined in
Section 2.2.1.
3.1.2 Underdrain Outlet — Sampling and Analysis
Underdrain outlet samples will be collected semi-annually from MSS-LF-UD1. The
underdrain outlet sampling location is defined in Section 2.2 of this Plan. Constituents
to be analyzed along with their respective analytical methods are listed in Table 1.
3.2 Leachate — Sampling and Analysis
On a semi-annual basis, discrete leachate samples will be collected from each sump sampling
port (MSS-LF-LCS1 through MSS-LF-LCS6) and a comprehensive leachate sample (MSS-LF-
LCSC) will be collected from the force main downstream of all six landfill cells, prior to
discharging to the leachate basin. The leachate sampling locations are defined in Section 2.3
of this Plan. Constituents to be analyzed along with their respective analytical methods are
listed in Table 1.
3.3 Field Collection Procedures
Sampling will be conducted at the locations defined in this Plan and in general conformance
with procedures provided in Appendix I.
Page 7 of 11

Industrial Landfill No. 1 1812-INDUS Revision 2, December 13, 2021
Environmental Controls Monitoring Plan
3.4 Analytical Procedures
The main analytical laboratory used in this program is the Duke Energy Central Laboratory
Services: NC Wastewater (#248) Certification.
Vendor laboratories that meet EPA and NC certification requirements may be used for
analyses with approval by Duke Energy.
The analytical procedures used for this Plan are listed in Table 1. The laboratory must report
any detection of any constituent (as revised in the October 27, 2006 NCDEQ Division
memorandum and February 23, 2007, addendum).
The laboratory certificates -of -analyses will, at a minimum, include:
• Narrative: The narrative will include a brief description of the sample group (number and
type of samples, field and associated lab sample identification numbers, preparation and
analytical methods used). The data reviewer will also include a statement that all holding
times and Quality Control (QC) criteria were met, samples were received intact and
properly preserved, with a brief discussion of any deviations potentially affecting data
usability. This includes, but is not limited to: test method deviation(s), holding time
violations, out -of -control incidents occurring during the processing of QC or field samples
and corrective actions taken, and repeated analyses and reasons for the reanalysis
(including, for example, contamination, failing surrogate recoveries, matrix effects, or
dilutions). The narrative will be signed by the laboratory director or authorized laboratory
representative, signifying that all statements are true to the best of the reviewer's
knowledge, and that the data meet the data quality objectives as described in this Plan
(except as noted). One narrative is required for each sample group.
• Original Chain -of- Custody Form;
• The laboratory will list all analytes for which the samples were analyzed;
• Dilution factors with a narrative of the sample results, including the reasons for the dilution
(if any);
• Blank Data: If organic analyses is required, the laboratory will report the results of any
method blanks, reagent blanks, trip blanks, field blanks, and any other blanks associated
with the sample group. For inorganic analyses, the laboratory will provide the results of
any preparation or initial calibration blanks associated with the sample group, and;
• QC Summary: The laboratory will provide summary forms detailing laboratory QC sample
results, which include individual recoveries and relative percent differences (if appropriate)
for the following Quality Assurance (QA)/QC criteria: surrogates, MS analyses, MSD
analyses, laboratory control samples, and sample duplicate analyses. QC control limits will
also be reported; if any QC limits are exceeded, a flag or footnote will be placed to indicate
the affected samples.
Additional QA data and/or other pertinent data may be reported as requested.
3.5 Quality Assurance and Quality Control Program
Duke Energy laboratory QC checks used by vendor laboratories are described in each
laboratory's generic Quality Assurance Plan and procedures manual. Using the Duke Energy
Page 8 of 11

Industrial Landfill No. 1 1812-INDUS Revision 2, December 13, 2021
Environmental Controls Monitoring Plan
laboratory QC checks, the vendor laboratories demonstrate the ability to produce acceptable
results using the methods specified.
QC checks used by the Duke Energy laboratory for sampling procedures and laboratory
analyses are conducted for each sampling event. These QC checks consist of the preparation
and submittal of field blanks, trip (travel) blanks, and/or field replicates for analysis of each of
the parameters at frequencies described in the laboratory(s) procedures manuals.
The field QC blanks and replicates that may be included as QC checks are described below.
The specific type and number of blanks used as listed below may vary depending on the
sampling event and will be determined by the Duke Energy field sampling personnel:
Field Blanks: A field blank consists of a sample container filled in the field with organic -
free, deionized, or distilled water prepared and preserved in the same manner as the
samples. The field blank is transported to the laboratory with the samples and analyzed
along with the field samples for the constituents of interest to check for contamination
imparted to the samples by the sample container, preservative, or other exogenous
sources. Field blanks are typically utilized for each sampling event. The field blanks are
typically analyzed for major anions and cations and metals.
Trip Blanks: If any samples are being analyzed for volatile organic compounds, a trip
blank is required. A trip blank is a sample container filled with organic -free water in the
laboratory that travels unopened with the sample bottles. The trip blank is returned to the
laboratory with the field samples and analyzed along with the field samples for parameters
of interest.
Field Replicates: A field replicate is a duplicate sample prepared at the sampling
locations from equal portions of the sample aliquots combined to make the sample. Both
the field replicate and the sample are collected at the same time, in the same container
type, preserved in the same way, and analyzed by the same laboratory as a measure of
sampling and analytical precision.
3.6 Validation of Field Data Package
The field data package includes the field records and measurements developed by the
sampling team personnel. The field data package validation will be performed by Duke Energy
personnel. The procedure for validation consists of the following:
• a review of field data contained on the Monitoring Data Sheets for completeness;
• verification that equipment blanks, field blanks, and trip blanks (if required) were properly
prepared, identified, and analyzed;
• a check of the Field Sampling Calibration Form for equipment calibration and instrument
conditions, and;
• a review of the COC Record for proper completion, signatures of field personnel and the
laboratory sample custodian, dates and times, and for verification that the correct analyses
were specified.

Duke Energy
Leachate Sampling Collection Guideline
1.0 General Information
1.1 Introduction
Revision 0, September 29, 2020
This Leachate Sample Collection Guideline (Guideline) describes the general
processes which Duke Energy or their designee should follow for collection of a
leachate sample at operational and closed Duke Energy landfills located at fossil
power plants (Plant/ Site).
The principal purpose of a sampling and analysis program is to provide data that
accurately reflect the quality of the media being investigated which begins with
assurance that the composition of field samples remains unaltered before laboratory
analysis. This Guideline provides information pertaining to preparation for, and field
collection of, a leachate sample.
1.2 Leachate Sampling General Requirements
In addition to the information provided in this Guideline, all personnel collecting
leachate samples from a Site will:
• be knowledgeable of general field collection procedures including operation of
equipment to be utilized, preservatives, and storage temperature requirements,
and familiar with this sampling procedure;
• wear personal protective equipment (PPE) required by the Site or based on field
conditions (may include a high visibility vest, hard hat, eye protection, gloves, and
protective footwear);
• be familiar with preservatives and/or storage temperatures required for the
parameters to be analyzed;
• confirm that receiving laboratory is aware of, and prepared to, accept the samples
prior to mobilizing for field collection;
• use new, clean, non -powdered latex or nitrile gloves at each sample collection
location;
• checked all equipment to ensure that it is in working order and if necessary,
calibrated;
• decontaminate reusable sampling equipment prior to collection of a leachate
sample;
• record detailed field notes in a logbook or dedicated field form to include sample
information (e.g. site name, time and date sample was collected, sample code,
personnel, weather etc.), and;
• document the chain of custody for each sample collected.
Leachate samples will be:
• collected in certified pre -clean containers appropriate for the laboratory analyte
which are labeled in accordance with Section 2.0, and supplied or recommended
Page 1 of 5

Duke Energy
Leachate Sampling Collection Guideline
Revision 0, September 29, 2020
by the laboratory performing the analysis, filled to the brim to avoid the inclusion of
air in the sample, unless there is a 'fill -to' mark (typically in pre -preserved bottles);
• collected at locations identified in the Compliance Monitoring Plan (CMP) unless
an alternate location is authorized by Waste and Groundwater Programs Subject
Matter Expert (SME) for the Site;
documented as "Insufficient Flow" and not sampled if a location is experiencing a
low flow condition that would preclude collection without entrainment of sediment,
and;
• stored in iced coolers, out of direct sunlight and delivered to the laboratory with
minimum delay; ideally on the same day and preferably within 24 hours of
sampling.
2.0 Labeling, Documentation, and Records
2.1 Sample Container Labeling
2.1.1 Prior to field mobilization
Field sample containers should be labeled and organized prior to mobilization for
field collection unless an emergent event precludes the ability to pre -label
containers.
2.1.2 At sample collection location
As samples are collected, field personnel record the date and time of collection
and initials of sampler on the container label and records that information on the
Monitoring Data Sheet and the Chain -of -Custody Record and Analysis Request
Form (example included as an attachment to this Guideline).
2.2 Field Documentation
Field documentation for each sample is recorded on the Field Monitoring Data
Sheets, Field Sampling Calibration Form, and Chain -of -Custody Record and Analysis
Request Form (COC Record). These sheets are arranged in sequential order and
filed by project and date.
Notations are made during field collection to document the following information:
• identification of location;
• date and time of collection;
• collection method;
• types of containers used;
• identification of Quality Control (QC) samples (if applicable);
• preservative(s) used;
• parameters for analysis;
Page 2 of 5

Duke Energy
Leachate Sampling Collection Guideline
• field analysis data and methods;
• field observations during sampling event
• name(s) of sample collectors(s), and;
Revision 0, September 29, 2020
• climatic conditions including an estimate of air temperature.
2.3 Chain -of -Custody Record
The COC Record accompanies the sample(s), traces sample possession from time of
collection to delivery to the laboratory(s), and clearly identifies which sample
containers have been designated for each requested parameter. The COC Record
includes the following information:
• sample identification number;
• signature of collector;
• date and time of collection;
• sample type (e.g., leachate);
• identification of location;
• number of containers;
• parameters requested for analysis;
• preservative(s) used;
• signature of all persons involved in the chain of possession, and;
• inclusive dates of possession.
3.0 Sample Collection
3.1 Grab Sample Method
The Grab Sample Method is simple and effective for a homogeneous sample matrix.
The use of unpreserved sample containers for direct grab sampling is encouraged
since the same container can be submitted for laboratory analysis after appropriate
preservation. This procedure reduces sample handling and eliminates potential
contamination from other sources.
Sampling personnel will use the container provided or recommended by the
laboratory for collecting samples that will be analyzed for oil and grease, volatile
organic compounds (VOCs), and microbiological samples.
Sample containers with premeasured amounts of preservative shall not be used to
collect field samples using this method.
If homogeneity is not apparent, based on known flow or vertical variations (not
assumed), then use other collection protocols.
General steps field collection of leachate using the Grab Sample Method are:
Page 3 of 5

Duke Energy Revision 0, September 29, 2020
Leachate Sampling Collection Guideline
1. Slowly submerge the container opening, neck first, into the sample media
(leachate).
2. Invert the bottle so the neck is upright and pointing towards the direction of flow (if
applicable). Allow leachate to flow slowly into the container until filled.
3. Return the filled container quickly to the surface.
4. Pour out a few mL of sample away from and downstream of the sampling location.
This procedure allows for the addition of preservatives and sample expansion. Do
not use this step for volatile organics or other analytes where headspace is not
allowed in the sample container.
5. add preservatives (if applicable), securely cap container, label, and complete field
notes.
If sample containers are attached to a pole via a clamp, submerge the container and
follow steps 3 — 5 but omit steps 1 and 2.
3.2 Unpreserved Container or Intermediate Vessel
If the sample cannot be collected directly into the sample container (e.g.: Grab
Sample Method) to be submitted to the laboratory, or if the laboratory provides pre -
preserved sample containers, use an unpreserved sample container or an
intermediate vessel (e.g., beakers, buckets or dippers) to collect the sample. Vessels
must be constructed appropriately, including any poles or extension arms used to
access the sample location.
General processes for field collection of leachate using an intermediate vessel or
container are:
Rinse the intermediate vessel with ample amounts of leachate water prior to
collecting the first sample.
• Use an intermediate vessel or unpreserved container collect the leachate sample
as outlined in the Grab Sample Method, Section 3.1.
• Use a pole mounted intermediate vessel or unpreserved container of appropriate
construction to sample at unsafe distances collect the leachate sample as outlined
in the Grab Sample Method, Section 3.1.
3.3 Peristaltic Pump and Tubing
This technique is not acceptable for Oil and Grease, EPH, VPH or VOCs. Extractable
organics can be collected through a peristaltic pump if flexible interior -wall Teflon,
polyethylene or PP tubing is used in the pump head.
The most portable pump for this technique is a 12-volt peristaltic pump. Use
appropriately precleaned, silicone tubing in the pump head and attach polyethylene,
Tygon, etc. tubing to the pump to fill the sample container.
4.0 Custody and Laboratory Receipt
4.1 Leachate Sample Custody
Page 4 of 5

Duke Energy
Leachate Sampling Collection Guideline
Revision 0, September 29, 2020
For the purpose of this Guideline, a sample is considered in custody if it is:
• in actual possession of the responsible person;
• in view, after being in physical possession, or;
• locked or sealed in a manner so that no one can tamper with it, after having been
in physical custody; or in a secured area, restricted to authorized personnel.
Samples are maintained in the custody of sampling personnel throughout the duration
of field collection. At the end of each day and prior to the transfer of the samples the
COC Record information is completed for each sample.
Upon transfer of leachate sample custody from sampling personnel to a currier or
receiving laboratory, the COC Record is:
signed by sampling personnel, including date and time.
if a currier is used for transporting the leachate sample, the COC Record is:
signed by the currier accepting the sample for transport, including date and time.
Upon arrival at the receiving laboratory the COC Record is:
signed and dated by the designee immediately following receipt by the
laboratory.
4.2 Laboratory Receipt
The laboratory maintains a sample -tracking record that follows the leachate sample
through each stage of processing. Sample tracking records maintain the date of
sample extraction or preparation, and analysis. The sample tracking records are used
to verify compliance with holding time limits during data validation and reviewed in
laboratory audits.
