1.0 INTRODUCTION
On behalf of the City of Charlotte (City), Geosyntec Consultants of NC, PC
(Geosyntec) has prepared this Water Quality and Landfill Gas Monitoring Plan for the
City of Charlotte’s Former York Road Landfill. This report presents the detailed plans
to monitor landfill gas (LFG) as well as groundwater and surface water at the former
landfill. This document replaces and consolidates the Water Quality Monitoring Plan
(WQMP; Delta, 2004) and the Landfill Gas Monitoring Plan (LGMP; HDR, 2011)
previously in place for the Former York Road Landfill.
1.1 Site Description and History
The Former York Road Landfill (herein referred to as the “Site”) is an approximately
400-acre Site located along West Tyvola Road and South Tryon Street (Highway 49) in
Charlotte, Mecklenburg County, North Carolina (Figure 1). The Site was operated as
an unlined municipal solid waste landfill from 1968 to 1986, with the last expansion
occurring in 1983 (under North Carolina Department of Environmental Quality
[NCDEQ] Facility Permit Number 60-03, Appendix A). The landfill waste placement
area consisted of approximately 168 acres, which was divided into six cells referred to
as Landfill Areas A through F. The precise locations of waste placement boundaries are
uncertain and have been estimated by others, as shown in Figure 2. The former landfill
was developed with the construction of West Tyvola Road, a golf course, and a
recreational park following closure in 1986. Today, the Site is utilized by the
Renaissance Park Golf Course and Renaissance Park, which include recreational
facilities for golf, softball, soccer, biking, and disc golf. In July 2016, some of the
athletic fields at Renaissance Park (including the softball and soccer facilities) were
closed to public use as a result of the effects of the former landfill on upkeep of the
fields. Other facilities including the golf course, bike trails, and disc golf courses
remain in operation.
1.2 Regulatory Authority
The North Carolina Department of Human Resources, Division of Health Services
released a closure letter for the York Road Landfill under title 10 North Carolina
Administrative Code (NCAC) 10G, Section .0500 rules on 21 August 1987. These
regulations were transferred and recodified into title 15A NCAC 13B Section .0500,
effective April 1990. Subsection .0510 for Closure Conditions states:
Water Quality and Landfill Gas Monitoring Plan
Former York Road Landfill, Charlotte, North Carolina
February 2017

GC5699A\Water Quality and Landfill Gas Monitoring Plan 2 02.2017
(c) When a solid waste disposal site has been closed in accordance with the
requirements of the Division, future necessary maintenance and water quality
monitoring shall be the responsibility of the owner and the operator and shall be
specified in the closure letter.
Current requirements for municipal solid waste landfill facilities (MSWLFs) are
codified in NCDEQ Solid Waste Rule 15A NCAC 13B Section .1601(c)(1) which
states:
(c) Applicability. Owners and operators of new and existing landfill facilities
including a MSWLF unit(s) shall conform to the requirements of this Section as
follows:
(1) Municipal solid waste landfill units which did not receive solid waste after
October 9, 1991 shall comply with the Solid Waste Permit, the Conditions of
the Permit, and Rule .0510 [referenced above].
The closure letter (Appendix B) was written under the old rules and does not specify
LFG monitoring requirements. The Facility Permit (Appendix A) also does not specify
provisions for LFG. Therefore, this monitoring plan has been developed taking into
account the regulations applicable to MSWLF landfills which received waste after
October 9, 1993 which require the following under 15A NCAC 13B Section
.1626(4)(a):
(a) Owners or operators of all MSWLF units must ensure that:
(i) The concentration of methane gas generated by the facility does not
exceed 25 percent of the lower explosive limit for methane in
facility structures (excluding gas control or recovery system
components); and
(ii) The concentration of methane gas does not exceed the lower
explosive limit for methane at the facility property boundary.
These regulations also require a routine methane monitoring program with a minimum
monitoring frequency of quarterly. These regulations, though not believed to be
specifically applicable to the Site, have been considered in the development of LFG
monitoring procedures in this document.

GC5699A\Water Quality and Landfill Gas Monitoring Plan 3 02.2017
NCDEQ Solid Waste Management Rules for groundwater (15A NCAC 13B. Sections
.0600, Rule .0601 and .1630 through .1637) specify groundwater monitoring systems,
sampling analysis requirements, detection and assessment monitoring, and corrective
measures. Surface water monitoring requirements are specified in 15A NCAC 13B.
Section .0600, Rule .0602. This monitoring plan has been developed in consideration
of the abovementioned rules for water quality monitoring.
Additionally, several guidance documents and memoranda were used in the
development of this monitoring plan. Guidance documents reviewed include Solid
Waste Section Guidelines for Groundwater, Soil, and Surface Water Sampling
(NCDENR, 2008), Division of Waste Management Solid Waste Section Landfill Gas
Monitoring Guidance (NCDENR, 2010), and Environmental Monitoring Data for
North Carolina Solid Waste Management Facilities (NCDENR, 2007).
1.3 Hydrogeologic and Geologic Setting
The Site is located within the Charlotte Belt of the Piedmont Physiographic Province.
The topography of the Piedmont Province is generally characterized by gently rolling
hills ranging in elevation from approximately 300 to 1,200 feet (ft) above mean sea
level (MSL), and the Site elevation ranges from approximately 580 to 680 ft above
MSL. Geologically, the province is comprised primarily of crystalline metamorphic
rocks (schists and gneiss, and to a lesser extent, phyllite and slate) of Precambrian to
Paleozoic age. These units are often highly deformed with multiple fracture and
foliation planes, which promote anisotropic groundwater flow. The occurrence and
movement of groundwater at the Site is typical of the Piedmont formation, and
generally occurs within two hydrogeologic units. A shallow hydrogeologic unit
typically occurs within the soils and saprolite (weathered residuum which mantles
bedrock). A deeper hydrogeologic unit is generally associated with secondary porosity
(fractures or open spaces) within the crystalline bedrock. A transition zone of fractured
bedrock occurs between saprolite and bedrock and is generally referred to as partially
weathered rock (PWR).
Groundwater flow in the shallow hydrogeologic unit is controlled by local topographic
features, where recharge occurs in upland areas and discharge occurs in drainage
features, such as streams, rivers, or lakes. Recharge to the shallow hydrogeologic unit
is primarily the result of infiltrating precipitation. Groundwater flow in the deeper
water-bearing zone is controlled by the distribution and degree of interconnection of
Water Quality and Landfill Gas Monitoring Plan

openings in the rock. A potentiometric surface map showing groundwater elevations
measured in March 2016 and inferred potentiometric contours is included on Figure 3
as a demonstration of typical groundwater elevations and flow directions at the Site.
In addition to groundwater, three surface water streams cross the Site: Sugar Creek (SC)
and two unnamed tributaries referred to as the north tributary (NT) and the south
tributary (ST). The locations of these surface water features are depicted on Figure 2.

2.0 LANDFILL GAS MONITORING PLAN
LFG monitoring is conducted due to potential explosion and asphyxiation hazards
which can be associated with methane gas. As organic material in a landfill
decomposes, it releases LFG which is approximately 50% methane (CH4) and
approximately 50% carbon dioxide (CO2), with some nitrogen (<5%) and other
compounds. As a landfill ages, peak methane production commonly tapers off and LFG
concentrations decrease, which often occurs over the course of 20 to 50 years or more.
LFG can migrate in the subsurface by diffusion and pressure gradients, and may find
preferential pathways through unsaturated soil. In this way, methane can reach the
surface through structures, buildings, or cracks in the surface cover. LFG can
accumulate beneath or inside these structures and reach explosive or asphyxiating
levels. Asphyxiation occurs through the displacement of oxygen by carbon dioxide and
methane or other gases such as hydrogen sulfide, creating an oxygen-deficient
environment. An oxygen-deficient environment is defined by the Occupational Safety
and Health Administration (OSHA) to have oxygen concentrations below 19.5% by
volume rather than ambient concentrations of 21%.
Methane is an explosive gas which combusts when a certain balance of methane and
oxygen, as well as a source of ignition, are present. Methane gas has a lower explosive
limit (LEL) of 5% by volume, below which the gas is generally too dilute for an
explosion. The upper explosive limit (UEL) for methane is 15% by volume, above
which there is generally insufficient oxygen present for the methane to ignite.
However, when concentrations are above the UEL there is a transition zone at some
point where the gas is present within the explosive limits. Therefore, methane
concentrations above the LEL indicate a potential hazard.
This LFG monitoring plan was developed to evaluate the presence of LFG in and
around the Site and to assess the following criteria:
1. The concentration of methane gas generated by the facility does not exceed 25
percent of the lower explosive limit for methane in facility structures (excluding
gas control or recovery system components); and

2. The concentration of methane gas does not exceed the LEL for methane at the
facility property boundary.

The following sections describe LFG control systems in place and monitoring activities
to be carried out at the Site.

2.1 Active Extraction Systems
Two methane extraction systems are active on the Site: one in the golf clubhouse, and
one along the northeast boundary, which are designed to limit LFG migration off-Site or
into facility structures. A third system is planned for construction along the northeast
boundary to supplement performance of the existing northeast boundary system. The
following sections describe these systems and their operation.
2.1.1 Golf Clubhouse Methane Vent System
The golf clubhouse venting system (also referred to as the Renaissance Park Pro Shop
methane vent system) is designed to vent methane from below the clubhouse gravel
base. The system also draws dilution air through the subsurface to prevent methane
migration toward the clubhouse. The input of ambient air reduces the applied vacuum
and dilutes the air beneath the building slab. The currently operating system was
installed in 1996 as described in the Project Final Report – Methane Remediation
System Construction (Law, 1996).
2.1.1.1 System Components
The clubhouse methane vent system is powered by a five horsepower Rotron
regenerative blower. Eight vertical vapor extraction points are connected through seven
manifolds and 31 horizontal polyvinyl chloride (PVC) pipes beneath the clubhouse
floor slab. An additional nine perforated vertical passive air infiltration vents are
distributed along the northern and southern walls of the clubhouse. The clubhouse
venting system layout is shown in Figure 4.
System components include:
1. 5 hp AMETEK-Rotron Regenerative Blower (Model EN707F72MXL);
2. 40 Gallon PRM Combination Moisture Knockout and Particulate Filter (MS-
80);
3. PRM Moisture Knockout High Level Switch;
4. System Restart Timer Interlocked with Moisture Knockout High Level Switch;
5. Control and Separate Breaker Panel;
Water Quality and Landfill Gas Monitoring Plan

GC5699A\Water Quality and Landfill Gas Monitoring Plan 7 02.2017
6. Vacuum Relief Valves (One AMETEK-Rotron diaphragm and one AMETEK-
Rotron mechanical relief valve);
7. Ashcroft Vacuum Gauge (0-60”H20);
8. AMETEK-Rotron 70-350 CFM Airflow Meter (Model FM30C350Q);
9. Panel Mounted AMP/Airflow Meter;
10. AMETEK-Rotron Blower Exhaust Muffler (Model 515185); and
11. Ashcroft Blower Discharge Pressure Gauge (0-60”H20).

Two building exhaust fans are located on the lower level of the clubhouse in the main
room and in the southern side room with associated powered louvers. The fan in the
southern side room is tied into the clubhouse methane alarm system (described in
Section 2.2) to activate when a methane alarm is triggered.

2.1.1.2 System Operation
For system operation, all breakers within the breaker panel should be set to the “ON”
position. In the control panel to the right of the breaker box, the “HAND-OFF-AUTO”
switch should be set to the “AUTO” position. The system can also be run with the
switch set to “HAND” for short periods but in this position the system will bypass the
high moisture separator knockout switch, and “HAND” mode is therefore not
recommended for regular use. To put the system in “HAND” mode the “START”
button must be pushed after setting the switch position. The “STOP” button or setting
the switch to “OFF” will turn the system off.
The “AUTO” position runs independently of the “START” and “STOP” buttons. The
system will shut down if the switch is positioned to “OFF” or if enough moisture
accumulates in the moisture knockout to trip the high moisture level switch. It will
restart automatically after gravity draining. Power loss, tripped breakers, or mechanical
failure may also turn the system off. If attempts to reset a breaker don’t work, or if
there is a mechanical failure, an electrician or a mechanical technician should be
contacted, respectively. To perform work on the system, turn the control panel switch
to “OFF” and turn off all breakers. The breaker panel should also be locked and tagged.
2.1.2 Northeast Boundary Methane Vent System
The northeast boundary methane vent system consists of active extraction wellpoints
screened within a gravel-filled trench connected to a blower system. It is intended to
Water Quality and Landfill Gas Monitoring Plan

February 2017

GC5699A\Water Quality and Landfill Gas Monitoring Plan 8 02.2017
capture methane prior to potential off-Site migration at the northeast property boundary
adjacent to Landfill Area D. The system was installed in 1990 and modified in 1995
and 2008.
2.1.2.1 System Components
The gravel-filled interceptor trench system is approximately 1,400 feet long and 17 feet
deep. The current configuration of the system includes extraction of subsurface vapors
from a series of 10 wellpoints installed within the gravel trench. These extraction wells
are connected via Landtec wellheads to a HDPE header pipe to the blower system
located within a fenced enclosure at the southeast end of the trench. A condensate drain
with a P-trap to provide a vacuum break from the system header is in place to drain
condensate to the subsurface.
Primary blower system components include:
1. 7.5 hp AMETEK-Rotron Regenerative Blower (Model EN808BA72XL);
2. 40 Gallon PRM Combination Moisture Knockout and Particulate Filter (MS-
80);
3. PRM Moisture Knockout High Level Switch;
4. System Restart Timer Interlocked with Moisture Knockout High Level Switch;
5. Vacuum Relief Valves (One AMETEK-Rotron diaphragm and one AMETEK-
Rotron mechanical relief valve);
6. Ashcroft Vacuum Gauge (0-60”H20) on Blower Piping;
7. AMETEK-Rotron Blower Exhaust Muffler (Model 515185).

2.1.2.2 System Operation
The northeast boundary vent system is operated by turning the power disconnect switch
to “ON”. This switch is located outside the enclosure and should be locked in place.
The system can be shut down by turning the switch to “Off” and locking it. It will also
shut down when the moisture knockout tank fills, tripping the high level moisture
switch and triggering gravity drainage after which the system will automatically restart.
Power loss and mechanical failure can also cause system outages and these shut downs
should be addressed by an electrician or mechanical technician.

GC5699A\Water Quality and Landfill Gas Monitoring Plan 9 02.2017
The locations of system extraction wells and the blower system are shown in Figure 5.
System operation can be reconfigured by adjusting wellhead valves to redistribute
vacuum within the trench. During recent years, the system wells have been configured
to focus vacuum on the central portion of the trench where relatively higher methane
readings were observed. Extraction wells SU-05, -06, -07, -02, -08, and -09 have been
operating, while the valves remain closed on SU-03R, -10, -01, and -11.
System performance is monitored by measuring vacuum levels, flow rates, and landfill
gas component concentrations at wellheads and at the system blower. Additionally,
vacuum levels at probes adjacent to the trench can be monitored to assess subsurface
influence, although vacuum influence outside the trench has not typically been
observed.
2.1.3 Planned LFG Migration Control System
Construction and operation of an additional active LFG migration control system along
the northeast boundary is planned, with startup anticipated in the first half of 2017.
Occasional detections of methane in off-Site subsurface probes near the northeast
boundary have indicated that methane migration past the existing NE boundary
extraction trench system may occasionally occur. Measurements and observations in
the vicinity of the extraction trench have indicated that a methane migration pathway
may be present in the subsurface between the bottom of the trench (approximately 17
feet below ground surface [ft bgs]) and the water table (approximately 30 ft bgs),
indicating that the existing extraction trench system is likely not providing vacuum
influence in this zone. The planned LFG migration control system will extract from
wellpoints screened at depths below the bottom of the trench and the water table.
2.1.3.1 System Components
The planned LFG migration control system will consist of 26 perimeter control (PC)
wells placed in a line along the NE boundary parallel to the existing NE boundary
methane vent system. Design drawings for the planned LFG Migration Control System
are included as Appendix C. The PC wells will connect to a header pipe supplied with
vacuum from a blower at the northwest end of the system.
Primary blower system components will include:
1. 20 hp Roots URAI 59 DSL Rotary Positive Displacement Blower;
Water Quality and Landfill Gas Monitoring Plan

February 2017

GC5699A\Water Quality and Landfill Gas Monitoring Plan 10 02.2017
2. Aluminum air-water separator and inlet vacuum filter
3. Exhaust silencer;
4. Vacuum relief valve;
5. Cellular telemetry;
6. 8 ft x 10 ft wood utility building enclosure with sound-attenuating insulation.
2.1.3.2 System Operation
The system is designed to operate continuously at a vacuum level of approximately 12
inches of mercury (in Hg) with a flow rate between 300 and 350 SCFM. The LFG
migration control system is designed to be operated concurrently with the existing
trench methane vent system, extracting vapors from depths lower than the bottom of the
extraction trench. System shutdown will occur when a high-level alarm in the moisture
separator is triggered, allowing the condensate to drain before restarting. Remote
monitoring of system status may be conducted through the integrated cellular telemetry
and sensors.
System monitoring and maintenance will be performed on a quarterly basis.
Monitoring activities include vacuum, flow, temperature, and gas composition
measurement at each wellhead and at the blower system. Additionally, nearby LFG
probes may be monitored for vacuum and gas composition at assess system
performance. The system blower requires quarterly maintenance including oil changing
and lubrication according to manufacturer recommendations. Adjustment of vacuum
can be made using the gate valve at each PC wellhead to focus vacuum as appropriate to
optimize performance. A condensate drain located at the southeast end of the system
header allows for gravity drainage of condensate from system piping. Access to the
drain is provided from a cleanout port inside a manhole at the drain location.
2.2 Landfill Gas Detection Systems
Methane detectors and alarms are present in several structures in and around the Site.
Combustible gas and methane detectors are installed in several on-Site and off-Site
buildings to provide continuous monitoring points and to alert building occupants
and/or the authorities in the event of methane detection. Three hard-wired alarm
systems are present at the Site in the golf course clubhouse, golf course maintenance
building, and softball field concessions building. These systems include Underwriters’
Laboratories (UL)-approved Macurco GD-2A combustible gas detectors installed in the
Water Quality and Landfill Gas Monitoring Plan
Former York Road Landfill, Charlotte, North Carolina
February 2017

GC5699A\Water Quality and Landfill Gas Monitoring Plan 11 02.2017
golf course clubhouse (19), the golf course maintenance building (8), and the softball
field concessions building (7). These three systems are wired to control panels that alert
monitoring services to dispatch authorities in the case of an alarm, and alert occupants
with audible alarms and warning lights.
Additionally, plug-in Macurco GD-21 methane detectors are installed in the on-Site
softball ticket booth (1 detector), on-Site golf course chemical storage building (1
detector), and off-Site Leatherman maintenance building (2 detectors). Two plug-in
First Alert Model GCO1CN methane alarms are located inside the off-Site John
Crosland School. Figures in Appendix D show the locations of combustible gas and
methane detectors within these buildings.
The LFG detection systems are inspected quarterly during LFG monitoring activities by
visually confirming alarm status. Additionally, annual inspection and testing of the
three hard-wired alarm systems is conducted annually by a low-voltage electrical
contractor (LEI Systems, Charlotte, NC).
2.3 Landfill Gas Monitoring Procedures
LFG concentrations are measured at designated locations including subsurface probes,
floor drains, and ambient air readings near surface structures. The procedures in this
LFG monitoring program were developed according to rules set forth in 15A NCAC
13B .1626(b). Specifically, considerations of soil, hydrogeologic, and hydraulic
conditions, as well as the locations of facility structures and property boundaries were
taken into account. Furthermore, experience from historical LFG monitoring conducted
at the Site was considered and incorporated into this plan.
2.3.1 Monitoring Schedule
Seventy-one LFG monitoring probes or extraction wells are included in the LFG
monitoring plan, and construction details for these probes are included in Table 1.
Quarterly LFG monitoring will be carried out at locations focused around the northeast
boundary and the South Tryon Street Corridor. Additionally, LFG monitoring probes
spaced at approximately 500 ft will be installed and monitored along the northern and
western Site boundaries. The LFG sampling schedule, including these LFG probes,
select Site structures as discussed below, and active extraction system components is
presented in Table 2.
Water Quality and Landfill Gas Monitoring Plan
Former York Road Landfill, Charlotte, North Carolina
February 2017

GC5699A\Water Quality and Landfill Gas Monitoring Plan 12 02.2017
LFG monitoring locations along the northeast boundary are shown on Figure 5. On-
Site and in the vicinity of the northeast boundary, seven passive methane probes will be
monitored (identified with a “MP” prefix), as well as ten extraction wells associated
with the northeast boundary extraction system (SU-01 through SU-11), and three in-
waste passive extraction wells (EW-1, EW-2, and EW-3). Thirteen off-Site subsurface
probes (identified with “BP” and “S” prefixes) near the 5146 Parkway Plaza Blvd (John
Crosland School) and 5260 Parkway Plaza Blvd buildings will be monitored to assess
the potential for off-Site LFG migration.
LFG monitoring locations along the South Tryon Street Corridor are shown in Figure 6.
Twenty on-Site LFG monitoring probes will be monitored along the southern property
boundary (with numerical identifiers and “RW” prefixes), as well as four off-Site LFG
monitoring probes (identified with “P” prefixes) across South Tryon Street, and one
LFG monitoring probe near the golf course maintenance building.
Along the northern Site boundary, eight LFG monitoring probes will be monitored
quarterly (40 through 47)1. Along the Sugar Creek boundary, five LFG monitoring
probes (31 through 35)1 and one groundwater monitoring well (DMW-05) will be
monitored for LFG quarterly. DMW-05 is screened partially in the vadose zone,
allowing for LFG monitoring in addition to groundwater sampling. These locations are
shown on Figure 7A.
LFG will also be monitored quarterly at selected Site structures where the potential for
gas to accumulate may exist. These include 40 light poles and five scoreboards located
around the Renaissance Park softball and soccer fields. Historical settlement has been
observed around light poles and scoreboards which occasionally has resulted in the
formation of surface cracking and voids, where methane has the potential to
accumulate. Storm drains are subsurface features which could allow for methane
accumulation, and forty-three selected storm drains on and around the Site will be
monitored. Additionally, floor drains in the Leatherman maintenance building, and
passive and active monitoring points in and around the golf course clubhouse will be
monitored. These locations are shown on Figure 6 and Figures 7A-7B.

1 LFG monitoring probes 44 through 47 and 31 through 35 are not installed at the time of this writing, and
are proposed based on implementation of this monitoring plan.

GC5699A\Water Quality and Landfill Gas Monitoring Plan 13 02.2017
In July 2016, some of the athletic fields at Renaissance Park (including the softball and
soccer facilities) were closed to public use. Mecklenburg County Park and Recreation
reported that ongoing settlement of the former landfill affected upkeep of the fields.
Decommissioning of field infrastructure, such as lighting, is under discussion. In the
case that Site structures such as light poles or scoreboards are removed, these locations
may be removed from the LFG monitoring plan.
The LFG monitoring locations were selected in consideration of historical data,
geologic and hydrogeologic information, potential receptors, and spatial coverage of
areas of interest. LFG monitoring probes are located with the highest frequency around
the northeast boundary and the South Tryon Street Corridor, where waste is located
closest to the property boundaries and physical barriers to subsurface migration (i.e.
streams) are not present. Past off-Site subsurface methane exceedances of the LEL
have been reported along both of these boundaries. The northeast boundary and South
Tryon Street Corridor also have off-Site structures closer to the waste than the other Site
property boundaries. Along the western and northwestern Site boundaries, streams
(Sugar Creek and the north tributary) lie along the property boundary or between the
waste and the property boundary, which present potential physical barriers to methane
migration, as subsurface migration typically primarily occurs through the vadose zone.
Monitoring of LFG probes spaced at approximately 500 feet frequency along these
boundaries will be conducted.
2.3.2 Monitoring Procedure
A handheld LFG monitor (i.e., CES Landtec GEM 2000 [GEM] or equivalent) with a
charcoal filter will be used to collect readings at methane probes. This instrument
reports CH4, CO2, oxygen (O2), and balance gas components of LFG. It also records
barometric pressure, and percent LEL of methane. A charcoal filter will be attached to
the sample tubing to remove volatile organic compounds other than the target
constituents out of the airstream. The gas meter will be calibrated daily according to the
manufacturer’s instructions.
Barometric pressure and weather conditions should be taken into consideration during
landfill gas monitoring. Landfills may vent more or less LFG depending on changes in
barometric pressure. Decreasing atmospheric pressure can lead to increased methane
venting as relatively higher pressure pushes methane to the atmosphere. Additionally,
saturated or frozen soil can lead to increased methane migration. As atmospheric
Water Quality and Landfill Gas Monitoring Plan

February 2017

GC5699A\Water Quality and Landfill Gas Monitoring Plan 14 02.2017
pressures are typically lower in the afternoon, landfill gas monitoring should be
conducted in the afternoon, as practical.
Sampling from LFG monitoring probes will be conducted by connecting the GEM
tubing to the vapor monitoring probe by means of the probe tubing or a well cap with
sample port. The tops of probes will be sealed to prevent air from entering while
readings are being taken. Readings from Site structures will be collected from within
structures where possible (e.g. storm drains), or from ambient air in the vicinity of
structures (e.g. light poles and scoreboards). If surface cracks or voids are observed at
monitoring locations, a reading will be taken from within the crack or void.
Concentrations will be recorded when the readings have stabilized to within 0.5%
volume on the instrument’s scale or the GEM vacuum has run for at least 60 seconds.
The vapor monitoring field log will include the facility name, permit number, GEM
serial number, calibration information (including date and time of calibration as well as
field calibration gas type and expiration date), field technician name, pump rate of the
GEM, and weather conditions. For each monitoring point the length of time purged;
time of reading collection; percent methane, oxygen, carbon dioxide, and LEL; and
other observations will be recorded. See Appendix E for an example field log form.
2.3.3 Site Inspection Procedure
The Site will be inspected quarterly to monitor the landfill cover and identify
abnormalities as per the closure letter. Site inspections will include identifying areas of
concern such as significant settlement or cracking in the landfill cover, formation of
subsurface voids, locations of methane venting, odors, distressed vegetation, areas of
leachate discharge, or exposed waste. Irregularities in the landfill cover such as cracks
or voids will be monitored for gas composition.
Site structures which are constructed on concrete pile caps with steel piles (e.g. light
poles and scoreboards at the baseball and soccer fields) have experienced settlement in
the surrounding soil which has occasionally resulted in the formation of subsurface
voids. The formation of voids or surface cracking presents an opportunity for methane
accumulation and/or venting to the surface. These structures will be inspected for
surface cracks or sunken holes, ailing vegetation, pools of water, an odor of refuse, and
stretching of electrical components.
Water Quality and Landfill Gas Monitoring Plan

February 2017

GC5699A\Water Quality and Landfill Gas Monitoring Plan 15 02.2017
Efforts should be made to observe as much of the landfill area surface as possible
during inspections. It is recognized that the entirety of the landfill surface may not be
visible or accessible due to areas of vegetation or other impedances.
2.4 Contingency Plan
The following procedures will be implemented when methane is observed to exceed
25% of the LEL in facility or surrounding structures, or if exceedances of the LEL are
observed in the subsurface beyond the Site boundary.
1. The City of Charlotte Fire Department (911) should be called in the event of
immediate danger to health or property (e.g. methane above the LEL in an
occupied building).
2. Regardless of immediate danger, the City of Charlotte Engineering and Property
Management department should be informed and the need for corrective actions
should be discussed.
3. NCDEQ (Jaclynne Drummond: 828-296-4706) should be contacted if there is
immediate danger. If there is no imminent threat to health or property, then
NCDEQ should be notified in the next semi-annual report.
2.5 Hazard Awareness Training
Training will be provided annually with stakeholders to review hazards associated with
the former landfill. The goal of this hazard awareness training will be to improve
awareness of potential hazards at the Site in order to protect the health of workers and
the public, and to protect the environment. Contingency plan procedures will be
reviewed in the training. Parties invited to participate may include workers or
representatives from Site or neighboring facilities (e.g., golf course and park
employees).

3.0 WATER QUALITY MONITORING PLAN
The water quality monitoring plan has been designed pursuant to NCDEQ Rules 15A
NCAC 13B .0601 (Groundwater Monitoring) and .0602 (Surface Water Monitoring).
Although not specifically applicable to the Former York Road Landfill, the water
quality monitoring procedures have been developed in general accordance with the
more detailed requirements presented in 15A NCAC 13B .1632, Groundwater Sampling
and Analysis Requirements, applicable to Municipal Solid Waste Landfills.
3.1 Compliance Boundary
According to NCDEQ rules, a compliance boundary is defined as a boundary around a
disposal system at and beyond which groundwater quality standards may not be
exceeded. The Solid Waste Permit for the facility (included in Appendix A) was issued
on 28 September 1983. NCDEQ Rule 15A NCAC 02L .0107 defines the compliance
boundary for this disposal system as follows:
“For disposal systems individually permitted prior to December 30, 1983, the
compliance boundary is established at a horizontal distance of 500 feet from the
waste boundary or at the property boundary, whichever is closer to the source.”
The compliance boundary as defined above is displayed on Figure 2. It should be
noted that the exact limits of waste are uncertain, and the limits of waste shown are
based on available historical information.
3.2 Groundwater Monitoring Wells
Twenty-six groundwater wells are present at the Site, which are listed with construction
details in Table 3, and locations depicted in Figure 2. Construction logs that are
available for Site wells are included in Appendix F. Fourteen of these wells (listed in
Table 4) are included in the groundwater monitoring well network, which provide
spatial coverage of the Site and screened intervals including multiple aquifer zones
(shallow, intermediate, and deep), allowing for collection of a representative set of
groundwater quality samples. These wells have historically been monitored at the Site,
providing a dataset to allow for evaluation of changes over time.
Monitoring well DMW-A is representative of background groundwater quality whereas
the remaining wells are monitored to assess groundwater downgradient or side-gradient
Water Quality and Landfill Gas Monitoring Plan
Former York Road Landfill, Charlotte, North Carolina
February 2017

GC5699A\Water Quality and Landfill Gas Monitoring Plan 17 02.2017
from waste cells. Five monitoring wells (DMW-02, DMW-05, YRW-07, YRW-10C,
and YRW-11B) are screened at less than 25 feet below ground surface (ft bgs) and
monitor shallow groundwater. Nine wells (DMW-A, DMW-01, DMW-02A, DMW-06,
DMW-08, DDW-01, DDW-02, DDW-03, and YRW-06A) monitor the intermediate
groundwater from 25 to 65 ft bgs, while the deep groundwater is monitored by three
wells (DDW-01A, DDW-03A, and DMW-02B) screened below 65 ft bgs.
In addition to these wells which are regularly sampled, water levels are measured from
six Site wells during monitoring events to allow for evaluation of the groundwater
potentiometric surface and flow direction. These wells are DDW-05, DDW-06, DMW-
09, DMW-B, YRW-06A, and YRW-07.
3.3 Water Supply Wells
Geosyntec reviewed Site historical information and publicly available data related to
water supply wells within approximately 2000 feet of the waste boundaries in February
2016. This survey included review of historical documents related to public water
supply wells (H&H, 2007), the Mecklenburg County Well Information System, records
from Charlotte Water, as well as a 2015 water supply well survey for the neighboring
Police & Fire Training Academy (located west of the Site, across Sugar Creek). The
locations of water supply wells identified from this review are depicted in Figure 8.
The results of the review indicated the following:
 Municipal water is available to the Site and properties adjacent to the Site,
although not all nearby properties are connected to public water. No water
supply wells have been identified on the Site. A water well located near the golf
clubhouse was abandoned in May 2001.
 WSW-1 (also referred to as the Robinson well) is located on a residential
property at 6423 South Tryon Street. This well is listed as “inactive” on the
Mecklenburg County Well Information System, and has been reported to be
inactive in a previous receptor survey.
 WSW-2 (also referred to as Cline 1) is located on a residential property at 6431
South Tryon Street. This well is listed as “active” on the Mecklenburg County
Well Information System. This well has been sampled annually as part of the
groundwater monitoring network. Historical groundwater data reviewed since
Water Quality and Landfill Gas Monitoring Plan
Former York Road Landfill, Charlotte, North Carolina
February 2017

GC5699A\Water Quality and Landfill Gas Monitoring Plan 18 02.2017
2008 showed that no volatile organic compounds (VOCs) have been detected in
WSW-2 during annual sampling. A detection of methyl ethyl ketone at 27
micrograms per liter (µg/L) was reported in WSW-2 in October 2006 (which is
below the 15 NCAC 02L standard [2L standard] of 4,000 µg/L). The well was
re-sampled in November 2006 and no VOCs were detected. It was theorized
that methyl ethyl ketone may have been a laboratory contaminant (H&H, 2007).
In February 2016, a Charlotte Water representative indicated that there are no
records of meter connections at this address, which indicates that the water
supply wells likely remain in use.
 WSW-3 (also referred to as Cline 2) is located on a residential property at 6505
South Tryon Street. This well is listed as “active” on the Mecklenburg County
Well Information System. This well has been sampled annually as part of the
groundwater monitoring network. Historical groundwater data reviewed since
2008 showed that no VOCs have been detected in WSW-2 during annual
sampling. In February 2016, a Charlotte Water representative indicated that
there are no records of meter connections at this addresses, which indicates that
the water supply wells likely remain in use.
 WSW-6 and WSW-6A, are located at a residence at 3232 Beam Road (also
listed as 3300 Beam Road). WSW-6 is 65 feet deep, and no longer active.
WSW-6A replaced WSW-6 and is an active drinking water well 185 feet deep.
This property is not connected to municipal water.
 WSW-7, located at 3300 Beam Road, is located on a property occupied by an
automotive repair shop. The well is reported to be 500 feet deep. The property
is not reported to have municipal water service. In 2015, the well was not
reported to be used for drinking water.
 WSW-13 (also referred to as Hildreth), located at 3140 Beam Road, is located
on a property currently owned by Mecklenburg County, which was reported to
be unoccupied in 2015. This well is reported to be 175 feet deep and not active.
No VOCs were detected in a review of analytical data from sampling this well in
2008 and 2009. A representative of the City of Charlotte indicated that this well
is not in use and is in consideration for abandonment.
Water Quality and Landfill Gas Monitoring Plan
Former York Road Landfill, Charlotte, North Carolina
February 2017

GC5699A\Water Quality and Landfill Gas Monitoring Plan 19 02.2017
Additionally, abandoned well WSW-8, formerly located at 3210 Beam Road, was
located on a property currently owned by the City of Charlotte, and has been reported to
have been abandoned in February 2016 by a representative of the City of Charlotte.
Other water supply wells that were previously abandoned are not included on Figure 8.
The seven water supply wells identified are located across Sugar Creek from the Site,
and groundwater on the west side of Sugar Creek has been observed to flow to the east,
toward Sugar Creek, based on a review of information from the Police & Fire Training
Academy site. The lack of historical detections in monitored water supply wells and
inferred groundwater flow direction toward the landfill lower the likelihood of the
landfill impacting these wells.
Two water supply wells, WSW-2 and WSW-3, will be sampled annually and analyzed
for VOCs during fall groundwater monitoring events as part of the groundwater
monitoring program. These two wells have historically been sampled annually as part
of the groundwater monitoring network for the Site (WSW-1 and WSW-13 have been
sampled on occasion during Site monitoring activities). WSW-2 and WSW-3 are both
active drinking water wells and are located southwest of the Site, in the direction of Site
groundwater flow (although likely the groundwater flow direction in these wells is
inferred to be toward the landfill).
3.4 Surface Water Monitoring System
The three streams passing through the Site (Sugar Creek, north tributary, and south
tributary) will be sampled to assess surface water quality. One sample will be collected
from a location generally upstream from waste cells in each stream, and one sample will
be collected downstream from waste cells in each stream, resulting in six surface water
sample locations. The selected locations allow for an assessment of possible impacts
from landfill-impacted water (e.g. groundwater of surface runoff) to surface water.
Surface water sample locations are depicted in Figure 2. Sample locations NT-01
(downstream) and NT-02 (upstream) are located on the north tributary. Sample
locations ST-01 (downstream) and ST-03 (upstream) are located on the south tributary.
Sample locations SC-01 (upstream) and SC-02 (downstream) are located on Sugar
Creek. With the exception of ST-03, these sample locations are consistent with
historical surface water sampling conducted at the Site. Former sampling location ST-

GC5699A\Water Quality and Landfill Gas Monitoring Plan 20 02.2017
02 has been replaced with ST-03, so that it is upgradient of Landfill Area D to provide a
sample more representative of conditions upstream of the landfill.
3.5 Groundwater and Surface Water Monitoring Schedule
Groundwater and surface water monitoring events will be conducted semi-annually
during the spring and fall of each year. Table 4 lists the monitoring locations, analyses
to be performed, and frequencies of sampling for groundwater wells, water supply
wells, and surface water monitoring locations.
3.6 Contaminants of Concern and Laboratory Analyses
Contaminants of concern (COCs) analyzed at the Site include select VOCs, the eight
Resource Conservation and Recovery Act (RCRA) metals, total iron, and total
manganese. Analysis of VOCs and RCRA metals are included at both groundwater and
surface water monitoring locations, while iron and manganese analyses will be
conducted on groundwater samples from select wells. Field blanks and Duplicate
samples will be analyzed for VOCs, RCRA metals, iron and manganese. The trip blank
will only be analyzed for VOCs. The constituents analyzed and wells sampled have
been included in historical monitoring conducted at the Site, allowing for analysis of
trends of constituents of interest in wells over time.
Water sample parameters to be analyzed as well as their holding times, Solid Waste
Section Limits (SWSLs), 2L Standards, NCAC 15A 02B standards (2B standards),
Federal Maximum Contaminant Levels (MCLs), and Chemical Abstracts Service (CAS)
registry numbers are included in Table 5. The SWSLs represent the lowest amount of
analyte in a sample that can be quantitatively determined with suitable precision and
accuracy, according to NCDEQ SWS rules. As practical, laboratory method detection
limits will be lower than the SWSL for each constituent.
Laboratory analyses will be conducted by a North Carolina certified laboratory. VOC
analysis will be performed by gas chromatography/mass spectrometry (GC/MS) using
USEPA method 8260. Metals samples will be analyzed for RCRA metals, total iron
and manganese using USEPA method 6010 (Inductively Coupled Plasma-Atomic
Emission Spectrometry, [ICP-AES]), and USEPA method 7470 (to analyze mercury).
Water Quality and Landfill Gas Monitoring Plan

February 2017

GC5699A\Water Quality and Landfill Gas Monitoring Plan 21 02.2017
Field parameters including pH, specific conductance, and temperature will also be
measured at groundwater, surface water, and supply well sampling locations, as
described in Section 3.7.2.
3.7 Groundwater Sampling Procedures
The following sections describe field methodology for groundwater sampling.
3.7.1 Depth to Groundwater Measurements
As per 15A NCAC 13B .1632 (d), static depth to groundwater measurements will be
collected at specified wells prior to sampling. Depth to groundwater measurements
should be collected within a short timeframe (generally within a single day) to reduce
temporal variations. Depth to groundwater data will be used to generate a
potentiometric surface map for the Site and to assess groundwater flow direction and
gradient. In addition, the depth to the bottom of each well should be measured and
compared to historical depth measurements to verify well integrity.
The depth to groundwater and total well depth will be measured using an electronic
water level indicator. The probe will be lowered into the well until it reaches water, at
which point an electrical signal will be sent to the meter which will emit a sound. The
indicator’s measuring tape will then be read at the height of the top of the well casing to
a reference notch or marking, where available. This measurement will be read to the
nearest 1/100th of a foot and recorded in a field log. The indicator’s sound will then be
muted and the probe lowered until the resistance of the bottom of the well is felt. This
total depth measurement will also be measured in reference to the top of the well casing.
After the measurements are collected, the water level probe will be decontaminated as
per Section 4.2.3.
3.7.2 Passive Diffusion Bag Sampling
Groundwater sampling of monitoring wells at the Site will be performed using dual-
membrane passive diffusion bags (PDBs). A comparison study of sampling procedures
was conducted at select Site wells in 2016, and the results were included in the Semi-
Annual Report – First Half 2016 (Geosyntec, 2016). The comparison study
demonstrated acceptability of passive sampling in the wells included in the study and
provided a recommendation for future sampling to be conducted using dual-membrane
PDBs.
Water Quality and Landfill Gas Monitoring Plan
Former York Road Landfill, Charlotte, North Carolina
February 2017

GC5699A\Water Quality and Landfill Gas Monitoring Plan 22 02.2017
Dual membrane PDB samplers (produced solely by EON Products, Inc. at the time of
this writing) are capable of collecting samples for analysis of both VOCs and inorganic
constituents. The dual membrane PDBs use two semipermeable membranes and rely on
the diffusion process where compounds will migrate across the membrane barriers.
Traditional PDBs have been widely used since the 1990s and feature a single membrane
capable of allowing VOCs to diffuse across it, but not larger molecules (such as metals).
Traditional PDB samplers consist of laboratory-grade water enclosed in a low-density
polyethylene (LDPE) sleeve, and are deployed to a target depth interval within a
screened zone or open borehole of a well. The samplers are then allowed to reach
equilibrium with the groundwater, at which time they are retrieved and the sample is
transferred to a standard laboratory container for submittal and analysis. The dual
membrane PDBs include a second, more porous upper membrane which allows larger
molecules including metals to diffuse across it. Therefore, the dual membrane PDBs
can be used to collect samples for analysis of both VOCs and metals.
Passive sampling of the Site wells may be employed during each sampling event in two
mobilizations. During the first mobilization to the Site, PDBs will be deployed in each
well at the approximate midpoint of the screened interval, or the midpoint of the water
column if the screen is not fully submerged. Prior to deployment, each PDB will be
filled with laboratory-grade deionized water. PDBs will be hung using a
decontaminated stainless steel weight and stainless steel wire or disposable, inert cord.
The end of the cord can be attached to the well itself or to a hook on the inside of the
well cap. The PDBs will be allowed to equilibrate within the wells for at least 21 days,
providing time for constituents within the wells to diffuse across the PDB membranes,
as well as to allow for vertical equilibration of constituents within the PDBs. During
deployment, it should be confirmed that at least two feet of water column is present
above the top of PDBs in each well to reduce the risk of the PDB to become exposed
above the water level, allowing VOCs to volatilize out of the PDB.
During a second mobilization, the water level and PDB depth should be measured again
prior to sampling to confirm PDB placement. PDB samplers will be recovered by
cautiously pulling them up with the wire or cord to prevent agitation. Each PDB will be
examined for tears or coatings. The bag will then be pierced with a disposable, small-
diameter discharge tube and water will be transferred to the sample bottles. Sampling
should occur immediately after recovering the bag. Field parameters (temperature, pH,
and conductivity) can be measured from remaining water within PDBs after sample
collection. If insufficient volume is available for field parameter measurement, field
Water Quality and Landfill Gas Monitoring Plan

GC5699A\Water Quality and Landfill Gas Monitoring Plan 23 02.2017
parameters can be measured by lowering a measurement probe down the well into the
screened zone, or by collecting additional volume using a bailer.
Samples shall be transported on ice, under chain-of-custody to the laboratory.
Sample collection should generally progress from wells with no historical impacts, or
low impacts, to wells with higher concentrations of COCs to reduce the risk of cross-
contamination.
3.7.3 Water Supply Well Sampling
Water supply well samples will be collected at the wellhead, if practical, or exterior
spigots on the side of each residence. A small volume of water will be purged prior to
sample collection. Water temperature will be measured periodically during purging to
monitor for stability. Once stable, sample collection will proceed by directly filling
sample containers.
3.8 Surface Water Monitoring Procedures
Surface water samples will be collected according to the NCDEQ’s Solid Waste Section
Guidelines for Groundwater, Soil, and Surface Water Sampling (NCDENR, 2008) grab
sampling method. Surface water samples will be collected from locations where flow is
occurring (if possible) and from locations away from the stream bank to minimize
disturbance to the stream bed. Downstream samples will be collected prior to upstream
samples. For containers without preservative, the laboratory-supplied bottle will be
submerged, neck first, into flowing water and then inverted and directed slightly
upstream. If preservative is to be added, a few milliliters of water will be discarded
downstream of the sampling location. If bottles are pre-preserved, the technician will
use a laboratory-provided, dedicated intermediate collection container to initially collect
the sample then transfer it to the sample bottles. Bottles will be inverted three times to
mix sample and preservative. Field parameters (temperature, pH, and conductivity) will
be measured using the intermediate collection container or by placing the multimeter in
the stream while avoiding contact with the bottom. An example field data sheet for
surface sampling efforts is included in Appendix E.
Water Quality and Landfill Gas Monitoring Plan
Former York Road Landfill, Charlotte, North Carolina
February 2017

GC5699A\Water Quality and Landfill Gas Monitoring Plan 24 02.2017
3.9 Sample Handling and Chain-of-Custody
Sample containers should arrive from the lab with a waterproof label containing the
analysis requested and preservatives included. The field technician will add the
following information to the label using a waterproof pen or marker: Site name, sample
ID, sample collection date and time, location, and sampler’s initials.
The information from the sample labels as well as the sample matrix and number of
filled containers of each type should be included on a chain-of-custody form provided
by the laboratory. This form will accompany the samples through the analysis and
sample names as well as dates and times of sampling matching the sample labels. The
chain-of-custody should be completed in blue or black ink and signed by the sampler(s).
Errors should be corrected by crossing out the line once and initialing the change. The
chain-of-custody is a serialized document and will become part of the laboratory record
and included in monitoring reports.
Samples will be shipped in a cooler on ice and cautiously packed to avoid breaking
bottles. Sample bottles will be bagged by sample location and ice will be separately
bagged to prevent cross-contamination. Where practical, the samples will be grouped
by expected contamination level (i.e. background groundwater samples will not be
placed in the same sample cooler as historically concentrated samples). The sample
cooler should be closed with a signed seal to demonstrate the integrity of the samples
during shipment. Samples should be analyzed within the holding times listed in Table
5.

4.0 QUALITY ASSURANCE AND QUALITY CONTROL
Quality assurance and quality control (QA/QC) will be implemented in the field and the
laboratory to demonstrate the integrity of the data.
4.1 Landfill Gas Monitoring
At the beginning of each day of LFG monitoring, the LFG meter should be calibrated
according to the manufacturer’s directions. The calibration gas should be
approximately 50% methane, 35% carbon dioxide, and 4% oxygen. Calibration shall be
documented and a copy of the record included in project records.
4.2 Water Quality Monitoring
QA/QC for water quality monitoring will include instrument calibration of the field
monitoring devices, QA/QC sample collection, laboratory QA/QC, and equipment
decontamination.
4.2.1 Field Meter Calibration
A field multimeter (YSI Professional Plus, or similar) will be used to measure field
parameters during groundwater and surface water monitoring. Multimeters shall be
field calibrated daily according to manufacturer specifications. Calibration shall be
documented in field forms.
4.2.2 Field Samples Quality Assurance/Quality Control
Field QA/QC samples will include field (rinsate) blanks, trip blanks, and field
duplicates. The QA/QC samples will be handled, shipped, and analyzed in the same
manner as other collected samples.
The field blank should be collected by rinsing non-dedicated field equipment (e.g. water
level meter) with distilled water following decontamination and collecting the rinsate
into sample bottles.
The trip blank will consist of VOC sample bottles filled with deionized water. These
containers will remain sealed but will be transported at the field Site as a collected
sample would be.
Water Quality and Landfill Gas Monitoring Plan
Former York Road Landfill, Charlotte, North Carolina
February 2017

GC5699A\Water Quality and Landfill Gas Monitoring Plan 26 02.2017
A duplicate sample will be collected at one groundwater monitoring well during each
sampling event. The duplicate will be collected at the same time and by the same
method as the regular sample. This will be achieved by deploying two PDBs within a
well and collecting a second set of samples. The purpose of the duplicate sample will
be to evaluate the reproducibility of the analytical results.
4.2.3 Equipment Decontamination
Non-dedicated sampling equipment, such as the water level indicator and stainless steel
weights, will be decontaminated before and after each use. Decontamination will be
conducted in general accordance with procedures described in Appendix A of Solid
Waste Section Guidelines for Groundwater, Soil, and Surface Water Sampling
(NCDENR, 2008).
Field decontamination will first consist of a wash using a decontamination mixture of
distilled water and laboratory-grade, phosphate-free detergent (i.e. Alconox® or
equivalent). Non-stainless steel parts should also be rinsed in 10 – 15 % reagent grade
nitric acid. After rinsing with distilled water, equipment will be rinsed with a pesticide-
grade isopropyl alcohol. The equipment will then be thoroughly rinsed using distilled
water. Equipment decontamination will occur just prior to using equipment to prevent
contamination during storage or transportation. If equipment will have sufficient time
to dry between uses, it should be decontaminated after use as well as before the next.
Decontaminated equipment will be transported in plastic sheeting or aluminum foil
once air-dried.

NOTES:
1. SEE DRAWING 2 NOTES FOR SURVEY AND EXISTING CONDITIONS
SOURCES.
2. THE CONTOURS AND ELEVATIONS OF THE PRESENT GROUND ARE
BELIEVED TO BE REASONABLY CORRECT AND ARE PRESENTED ONLY
AS AN APPROXIMATION. HOWEVER, THE CONTRACTOR SHALL SATISFY
ITSELF AS TO THE EXISTING CONTOURS AND ELEVATIONS. TRENCHES
SHALL BE EXCAVATED TO THE ALIGNMENTS SHOWN ON THE DRAWINGS.
CONTRACTOR SHALL BE RESPONSIBLE FOR STAKING OUT AND
REVIEWING THE PROPOSED TRENCH ALIGNMENTS IN THE FIELD BEFORE
STARTING TRENCHING WORK. TRENCHING AND DRILLING IS
ANTICIPATED TO BE CARRIED OUT IN SOIL, OUTSIDE THE LIMITS OF
WASTE.
3. CONTRACTOR SHALL PERFORM A GEOPHYSICAL SURVEY TO IDENTIFY
SUBSURFACE UTILITIES WITHIN THE WORKING AREA. PRIOR TO
TRENCHING, THE EXISTING HEADER AND LATERAL PIPES ASSOCIATED
WITH THE ACTIVE TRENCH EXTRACTION SYSTEM, AS WELL AS ANY
OTHER BURIED UTILITIES IN THE WORK AREA SHALL BE IDENTIFIED AND
MARKED. CONTRACTOR SHALL OBTAIN A DIG TICKET FROM NORTH
CAROLINA 811 TO BE MAINTAINED DURING GROUND-DISTURBING
ACTIVITIES AS REQUIRED BY LOCAL REGULATIONS.
4. NORTHING, EASTING, AND GROUND SURFACE ELEVATION ARE
APPROXIMATE. WELL AND HEADER LOCATIONS SHALL BE STAKED BY
CONTRACTOR AND APPROVED BY OWNER'S REPRESENTATIVE PRIOR
TO CONSTRUCTION. LOCATIONS OF PC WELLS, LATERALS, AND HEADER
PIPES MAY VARY TO ACCOMMODATE FIELD CONDITIONS. WELL
LOCATIONS MAY ALSO CHANGE IF OBSTRUCTIONS ARE ENCOUNTERED
DURING WELL DRILLING.
5. SOLID PVC LENGTHS IN WELL TABLE REPRESENT LENGTHS FROM
GROUND SURFACE. ACTUAL PIPE LENGTHS WILL BE SLIGHTLY LESS, AS
WELL RISERS TERMINATE BELOW GROUND SURFACE.
6. MINIMUM BOTTOM TRENCH WIDTH SHALL BE 1.5 TIMES THE PIPE
DIAMETER BUT NOT LESS THAN 18 INCHES. MINIMUM TRENCH SLOPE
SHALL BE 2%. SLIGHT ADJUSTMENTS IN THE DEPTHS AND ALIGNMENTS
WILL BE NECESSARY TO MAINTAIN A MINIMUM COVER OF TWO (2) FEET.
DECREASE IN HEADER PIPE SLOPE IS NOT ACCEPTABLE.
7. PRESSURE TESTING SHALL BE PERFORMED BY THE CONTRACTOR ON
HEADER PIPES AND LATERALS FOR A PERIOD OF ONE HOUR. ALL
PRESSURE TESTING FOR GAS PIPES SHALL BE DONE AT 10 PSIG. A TEST
SHALL BE ACCEPTABLE IF THE PRESSURE DROP AT THE END OF THE
ONE HOUR PERIOD IS LESS THAN 5 % OF THE TESTING PRESSURE.
8. CONTRACTOR SHALL BE RESPONSIBLE FOR SECURITY OF MATERIALS
AND EQUIPMENT. THE SITE IS NOT IN A SECURED AREA.
9. DISTURBED AREAS SHALL BE RE-VEGETATED AND STABILIZED BY THE
CONTRACTOR. ANY DAMAGE TO EXISTING STRUCTURES OR GAS
SYSTEM COMPONENTS SHALL BE REPAIRED AND RESTORED TO
EXISTING CONDITIONS BY CONTRACTOR AT NO COST TO OWNER.
10. CONTRACTOR SHALL PROVIDE AN AS-BUILT SURVEY OF NORTHING,
EASTING, AND ELEVATIONS OF THE PC WELLS, CONDENSATE DRAIN,
AND BLOWER SYSTEM LOCATION.

MAINTENANCE NOTES:
MAINTENANCE NOTES:
1. Inspect sediment fences at least once a week and after each rainfall. Make any required repairs
immediately.
2. Should the fabric of a sediment fence collapse, tear, decompose or become ineffective, replace it
promptly.
3. Remove sediment deposits as necessary to provide adequate storage volume for the next rain and
to reduce pressure on the fence. Take care to avoid undermining the fence during cleanout.
4. Remove all fencing materials and unstable sediment deposits and bring the area to grade and
stabilize it after the contributing drainage area has been properly stabilized.
