EC 12J
Charlotte, NC 28202
The revised Environmental Control Monitoring Plan (ECMP; Revision 2) for the North Starter Landfill
(NSLF) (3619-INDUS), located in Gaston County, North Carolina, is enclosed for review and approval, and
proposed to supersede the previously revised and approved ECMP Revision 1 dated February 26, 2021.
This ECMP has been updated primarily to incorporate the following items:
• Construction drain sampling locations (ALN-NSLF-CD1 and ALN-NSLF-CD2);
• Leachate basin leak detection monitoring location (ALN-LDSC); and
• Revised constituents and analytical methods in accordance with harmonized list approved by
the Section in a letter dated March 20, 2023.
The leachate basin leak detection monitoring location was incidentally missed in previous ECMP
versions.
NSLF construction drain design and installation was approved by the Section in a letter dated March 9,
2022. The construction drain began producing discharge in June 2022 and currently remains
operational, although drain flow is anticipated to cease sometime in 2025 based on groundwater
modeling information provided to the Section on March 2, 2022.
Other minor revisions to this ECMP include updated aerial photography, water level contours, and well
locations on Drawing 3, as well as updated leachate force main piping (as depicted in the NSLF Permit to
Construct Modification approved January 26, 2023).

North Starter Landfill (3619-INDUS) Revision 2, June 28, 2023
Environmental Controls Monitoring Plan
1.0 Introduction
This Environmental Controls Monitoring Plan (Plan) for the Duke Energy Allen Steam Station (Allen,
Station, Site) establishes locations and procedures for monitoring early detection of solid waste or
leachate potentially released to the environment from the North Starter Landfill (NSLF, landfill) and
leachate impoundment (leachate basin).
The landfill is situated partially within the Retired Ash Basin (RAB) 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 (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 Active Ash Basin (AAB), RAB, and RAB Ash Landfill.
The leachate basin is designed and constructed in accordance with NCAC 15A 13B .1680. Per NCAC
15A 13B .1680(e)(6), this Plan is intended to satisfy the requirements of a groundwater monitoring
system "consistent with or equivalent to" the requirements for the landfill unit per NCAC 15A 13B
.1631(e).
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 25-acre landfill is located partially within the western portion of the RAB, west
of the Powerhouse and south of Plant Allen Road (Drawing 1). The NSLF is bound by Plant
Allen Road to the north, the RAB to the south and east (specifically the Distribution of Residual
Solids [DORS] Fills to the east), and upland areas to the west (Drawing 2).
The approximate 3-acre leachate basin is located within the northwestern portion of the AAB
and bounded by the RAB to the north, AAB to the east and south, and upland areas to the
west (Drawing 2).
Leachate is conveyed from the landfill to the leachate basin via a forcemain piping network.
The leachate basin ties into an existing 36-inch wastewater forcemain where it is comingled
with Plant wastewater and subsequently sent to the Lined Retention Basin (LRB) for
treatment. Flows from the LRB are discharged to the Catawba River (Lake Wylie) through
Outfall 006 in accordance with NPDES Permit NC0004979 (Drawing 2). The landfill and
leachate basin engineered base liner are designed with a leak detection system (LDS) for
monitoring integrity of the liner system.

North Starter Landfill (3619-INDUS)
Environmental Controls Monitoring Plan
Revision 2, June 28, 2023
The RAB, which partially underlines the landfill, received CCR via sluice lines beginning in
1957 until 1973. In 1973, the AAB was constructed and placed into operation. The AAB
received CCR via sluice lines beginning in 1973. The AAB ceased receipt of fly ash in 2008
and ceased receipt of bottom ash in 2019. Additional details are as follows:
In 2008, the facility converted from a wet fly ash handling system to a dry fly ash handling
system. Since 2008, fly ash has been disposed in the on -Site RAB Ash Landfill.
Sluicing of bottom ash to the AAB continued until early 2019 when the facility converted to
a dry bottom ash collection system.
All CCR material is currently handled dry. Allen currently operates as peak -demand station,
which means it produces power (and by consequence, CCR) only when the grid demand is
exceptionally high, such as periods of above -average high temperatures in the summer and
below -average low temperatures in the winter.
The ash basins have contributed CCR-related constituents to groundwater at the Site. Since
the NSLF is situated partially over an area of known effects from the historical ash basin
operations, potential influence from the NSLF will be indistinguishable from existing CCR
effects in groundwater.
Groundwater from beneath and in the vicinity of the ash basins is sampled and analyzed
according to the NCDEQ approved monitoring plan which meets the requirements of the Coal
Ash Management Act (CAMA).
Groundwater associated with the NSLF and CCR Multiunit 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 Allen 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, the deep (transition
zone) flow zone, and the bedrock flow zone.
The ash basins, DORS fills, RAB Ash Landfill, NSLF, and leachate basin are contained within
former perennial stream valleys (flow compartment) (Drawing 1). Groundwater within the flow
compartment is a flow -through system. Groundwater enters the system from the upgradient

Environmental Controls Monitoring Plan
Revision 2, June 28, 2023
end near the NSLF and flows laterally through the central portion of the system and downward
near the dam, or downgradient end. A groundwater divide is located primarily west of the Site
and roughly follows topography along South Point Road and topographic highs north of the
RAB along Plant Allen Road to the Discharge Canal, and south of the AAB near Reese Wilson
Road. The topographically controlled flow direction provides natural hydraulic control of
constituent migration from the ash basins and adjacent sources within the flow compartment.
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 NSLF, leachate basin, AAB, RAB, and RAB Ash Landfill is provided as
Drawing 3. The primary flow path of the groundwater remains generally west to east 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 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
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 the landfill sump identified as ALN-
NSLF-LDS1, as well as in the vicinity of the leachate basin identified as ALN-LDSC
(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.

North Starter Landfill (3619-INDUS)
Environmental Controls Monitoring Plan
Revision 2, June 28, 2023
The landfill is designed for leachate to flow to one sump. 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;
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)
Page 4 of 11

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 138 .0602)
Surface water quality monitoring is not required for the landfill.
Stormwater is directed via channels around the perimeter of the landfill to a
NPDES permitted wastewater unit or NPDES permitted outfall.
This Plan will be reviewed if the path of stormwater leaving the landfill area will
be altered or permit status for receiving NPDES wastewater unit(s) will change.
The Division will be consulted to determine if surface water monitoring
requirements should be revised for monitoring of stormwater leaving the landfill
area.
2.2.1.2 Construction Drain Outlet — Monitoring
Construction drain outlet water samples are collected and analyzed on a semi-
annual basis from sample locations designated as ALN-NSLF-CD1 and ALN-
NSLF-CD2. ALN-NSLF-CD1 and ALN-NSLF-CD2 are at the terminus of
discharge pipes located south of the southeastern corner of the NSLF. The
construction drain outlet sample locations are shown on Drawing 2.
At the time of this Plan revision (Revision 2), ALN-NSLF-CD1 is sealed off with a
blind flange and is not anticipated to be utilized for construction drain discharge
for the remaining duration of construction drain operation. Therefore, construction
drain discharge samples are anticipated to be routinely collected from ALN-
NSLF-CD2; however, in special cases, construction drain discharge flows could
be switched to ALN-NSLF-CD1 if needed. Only one construction drain discharge
pipe is anticipated to be operational at a time.
Construction drain 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 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
Page 5 of 11

North Starter Landfill (3619-INDUS) Revision 2, June 28, 2023
Environmental Controls Monitoring Plan
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 (pg/L), except for field
parameters;
■ laboratory method detection limits, and;
■ comparison to appropriate 02B Standards with exceedances shown in
bold.
2.2.2.2 Construction Drain Outlet — Reporting
Construction drain 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.
Construction drain outlet samples ALN-NSLF-CD1 and ALN-NSLF-CD2 are
within an NPDES-permitted wastewater unit and pass through an NPDES
permitted outfall downstream; therefore, sample results from the construction
drain outlet will not be compared to water quality standards.
Construction drain 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:
o analytical results reported in micrograms per liter (pg/L), except for field
parameters
o laboratory method detection limits.

defined in Section 2.3 of this Plan, that location will have a note indicating the
reason a sample was unable to be obtained
3.0 Sampling and Analysis
Surface water, construction drain outlet flow, and leachate samples will be collected and analyzed as
described in this section.
3.1 Water Quality
3.1.1 Surface Water— Sampling and Analysis

This section will be revised if surface water quality monitoring is required in
Section 2.2.1.
Page 7 of 11

North Starter Landfill (3619-INDUS) Revision 2, June 28, 2023
Environmental Controls Monitoring Plan
3.1.2 Construction Drain Outlet — Sampling and Analysis
Construction drain outlet samples will be collected semi-annually from ALN-NSLF-CD1
and ALN-NSLF-CD2. The construction drain outlet sampling locations are 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
Leachate samples will be collected semi-annually from the sump sampling port (ALN-NSLF-
LCS1), and a comprehensive leachate sample will be collected (ALN-LCSC) from downstream
of the NSLF and SSLF, 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.
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;
Page 8 of 11

North Starter Landfill (3619-INDUS)
Environmental Controls Monitoring Plan
Revision 2, June 28, 2023
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
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.
3.7 Validation of Laboratory Data
The laboratory will perform a validation review of the submitted samples and analytical results
to confirm that the laboratory QA/QC requirements are acceptable.
4.0 Environmental Controls Monitoring Reporting
4.1 Environmental Controls Monitoring Report Submittal
A semi-annual report of monitoring results for the landfill and leachate base liner LDS, water
quality, and leachate will be submitted to the Division within 120 days following the date of
sampling.
The report will include, at a minimum:
• a completed NCDEQ Environmental Monitoring Report Form (Appendix II);
• a figure that includes relevant facility features and monitoring locations sampled as a part
of this Plan;
• engineered base liner leak detection system monitoring results for the landfill and leachate
basin;
• sampling and analysis data including:
o monitoring data sheets;
o field calibration forms;
o COC records;
o laboratory QA data, and;
o data validation checklists
an Electronic Data Deliverable (EDD) spreadsheet in required Division format for analysis
data;

Duke Energy
Landfill Sample Collection Guideline
1.0 General Information
1.1 Introduction
Revision 1, December 14, 2020
This Sample Collection Guideline (Guideline) describes the general processes which
Duke Energy or their designee should follow for collection of a 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 sample.
1.2 Sampling General Requirements
In addition to the information provided in this Guideline, all personnel collecting
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 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.
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
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);

Duke Energy
Landfill Sample Collection Guideline
Revision 1, December 14, 2020
• collected at locations identified in the Environmental Controls Monitoring Plan
(ECMP) 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;
• field analysis data and methods;

Duke Energy Revision 1, December 14, 2020
Landfill Sample Collection Guideline
• field observations during sampling event
• name(s) of sample collectors(s), and;
• 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;
• 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 using the Grab Sample Method are:

Duke Energy
Landfill Sample Collection Guideline
Revision 1, December 14, 2020
1. Slowly submerge the container opening, neck first, into the sample media.
2. Invert the bottle so the neck is upright and pointing towards the direction of flow (if
applicable). Allow media 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 using an intermediate vessel or container are:
• Rinse the intermediate vessel with ample amounts of media prior to collecting the
first sample.
• Use an intermediate vessel or unpreserved container collect the 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 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 Custody of Sample
For the purpose of this Guideline, a sample is considered in custody if it is:

Duke Energy Revision 1, December 14, 2020
Landfill Sample Collection Guideline
• 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 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 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 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.
