Winston-Salem/Forsyth County Utilities i Landfill Gas Monitoring Plan: Old Salisbury Road C&D Landfill ���
Introduction
1 Introduction
This Landfill Gas Monitoring Plan for the Old Salisbury Road Construction and Demolition Debris
(C&D) Landfill (OSR), is intended to update and replace the plan last approved in April of 2015 as
part of the previous permit renewal process.
1.1 Facility Background
The OSR landfill is permitted for 56 acres and is situated within a 140-acre tract north of Friedberg
Church Road and west of Old Salisbury Road in Forsyth County, North Carolina. The site is
accessed via Old Salisbury Road (State Road 3011). The Davidson County line borders the site
to the south. The location of the OSR landfill is illustrated on Figure 1.
1.2 Regulatory Authority
The site is operated under North Carolina Department of Environmental Quality (NCDEQ) facility
permit number 34-12. The facility was first issued a permit to operate on July 3, 1996 and opened
in August of the same year. The monitoring requirements for this site are addressed by North
Carolina Solid Waste Management Rule 15A NCAC 13B .0544. This plan addresses the
monitoring requirements for landfill gas.
Per 15A NCAC 1313.0544 (d), owners or operators of C&D landfill units must ensure that:
the concentration of methane or other explosive gases generated by the facility does not
exceed 25% of the lower explosive limit (LEL) (1.25% methane; 1 % hydrogen sulfide) in
facility structures (excluding gas control or recovery system components); and
The concentration of methane or other explosive gases does not exceed the LEL (5%
methane; 4% hydrogen sulfide) at the facility property boundary.
In addition, owners or operators of C&D landfill units must implement a routine monitoring
program and perform monitoring on at least a quarterly basis. If regulatory limits for
concentrations of methane or other explosive gases are exceeded, a contingency plan must be
implemented for the protection of human health and safety.
1.3 Geologic Characteristics
This section paraphrases the descriptions provided in the July 2003 Ground Water Monitoring
Plan and the 2003 Design Hydrogeologic Investigation Report.
1.3.1 Regional Geologic and Hydrogeologic Frame Work
According to the 1985 Geologic Map of North Carolina, OSR is located in the Charlotte belt of the
Piedmont Physiographic Province. This province contains metamorphic and igneous plutonic
rocks, which in some areas have been extensively weathered and eroded forming an undulating
and well -dissected topography. The area is underlain by granite rock, which is commonly
megacrystic to equigranular in texture.
The bedrock is typically fractured and is overlain by highly weathered bedrock called saprolite.
The saprolite varies in thickness from a few feet near bedrock outcrops to over 100 feet. The

Winston-Salem/Forsyth County Utilities I Landfill Gas Monitoring Plan: Old Salisbury Road C&D Landfill ���
Introduction
saprolitic material retains some of the original (relict) structural features of the parent rock. The
nearer surface residual soils are formed by the in -place physical and chemical weathering of the
saprolite and usually do not retain the relict structural features.
Subsurface conditions generally consist of a veneer of topsoil underlain by residual soils,
saprolite, partially weathered rock, and fractured rock. There is generally a gradual transition from
one material type to the next with varying thickness of each.
In the Piedmont Physiographic Province, groundwater is present within the openings created by
fractures and joints within the bedrock and within the pore spaces of the overlying-saprolite. The
saprolite/bedrock aquifers are primarily recharged by precipitation in the inter -stream areas, which
infiltrates through the unsaturated zone to the water table. The depth to ground water is generally
deeper beneath uplands than beneath valleys. The water table is commonly close to the top of
bedrock and is more often than not, located within the saprolite. Groundwater moves laterally and
downward through the saprolite and bedrock toward streams, springs, and surface water bodies.
The water table surface is generally a subdued reflection of the surface topography.
1.3.2 Site Specific Topography and Drainage
Surface drainage at the subject site is primarily controlled by a north -northwesterly trending ridge
within the property. Construction of the landfill generally mimics and replaced the natural ridge
that existed prior to the landfill. This ridge directs runoff northeast, west and southwest into
tributaries of South Fork Muddy Creek. The majority of surface runoff within this site is directed to
South Fork Muddy Creek on the north. A small area in the extreme southeasterly section of the
site appears to drain south into Miller Creek. Both the South Fork Muddy Creek and Miller Creek
flow to the west where they converge with Muddy Creek. Muddy Creek flows to the south and
converges with the Yadkin River.
1.3.3 Site Specific Hydrogeology
As documented in the Design Hydrogeological Investigation Report submitted by HDR on
December 2, 2003, the uppermost unconfined aquifer underlying the facility is comprised of three
units. The stratigraphic downward progression of the three units is saprolite transitioning into
partially weather bedrock, then competent bedrock. Ground water flow through the saprolite and
partially weathered bedrock is through the soil matrix, while groundwater flow through the bedrock
is primarily fracture flow.
Based on historical field observations (i.e., soil boring records) and laboratory test results from the
2003 Design Hydrogeological Investigation Report, the uppermost unconfined aquifer beneath the
facility predominantly exists within the unconsolidated saprolitic soil and transition zone units that
have been classified as micaceous silty sands and sandy silts produced by the in -situ weathering
of the granodiorite parent rock. Groundwater flow within the uppermost aquifer is predominantly
porous flow through the unconsolidated units. There is no evidence of discrete flow patterns within
the saprolite and transition zones of the uppermost aquifer resulting from relict quartz veins, dikes,
healed fractures, or strong preferential alignment of minerals (i.e., foliation). In general, the flow of
groundwater occurs for the facility is from higher elevations onsite to lower elevations onsite under
unconfined (water table) conditions regardless of the unit in which it resides. As such, the static
water table generally mimics the topography.

1.4 Monitoring History
A Ground Water Monitoring Plan was originally prepared by S&ME and submitted by HDR with
the Site Plan Application in 1995. HDR has subsequently revised this plan multiple times,
including adding a landfill gas monitoring plan by letter: August 1999, October 1999, October
2002, April 2003, July 2003, and April 2015. The plan with the amending letters was last
submitted to NC DENR in the April 2015 operating permit amendment. .

2.1 Landfill Gas
A monitoring network of 14 probes in 12 locations and one structure has been established at the
site. The network is intended to ensure that:
• The concentration of methane gas or other explosive gases generated by the facility
does not exceed 25 percent of the lower explosive limit in on -site facility structures
(excluding gas control or recovery system components);
• The concentration of methane gas or other explosive gases does not exceed the lower
explosive limit for methane or other explosive gases at the facility property boundary;
and
• The facility does not release methane gas or other explosive gases in any concentration
that can be detected in offsite structures.
In addition, monitoring of the network may be used to identify if landfill gas is impacting
groundwater constituents.
3 Sampling Schedule
Data will be collected from the fourteen (14) landfill gas probes and from within and around the
landfill scalehouse quarterly.
4 Landfill Gas Monitoring Procedures
This section describes standard procedures to be followed during field sampling events.

Winston-Salem/Forsyth County Utilities I Landfill Gas Monitoring Plan: Old Salisbury Road C&D Landfill ���
Data Evaluation
4.1 Equipment
Readings at the monitoring points will be collected using a handheld landfill gas monitor (i.e.,
CES Landtec GEM 2000 or equivalent). The meter shall be equipped with the applicable filters.
Commonly used filters include moisture, particulate and charcoal. A charcoal filter can be used
to help prevent volatile organic compounds from triggering a false positive reading. The meter
shall be calibrated according to the manufacturer's instructions.
4.2 Sampling
1. Record barometric pressure at the beginning of each event.
2. If necessary, remove the cap from the monitoring point and quickly attach the
appropriately sized adapter to the monitoring point.
3. Attach the gas analyzer tubing to the monitoring point.
4. Record the following gas concentrations once they have stabilized.
• % Methane, CHa
• % Carbon dioxide, CO2
• % Oxygen, 02
• ppm of Hydrogen Sulfide, H2S
• ppm of Carbon monoxide, CO
• % of balance gas as a check
5. Note if gas levels decrease before stabilizing
6. Disconnect the tubing and securely replace the original cap on the monitoring probe,
as necessary.
7. Proceed to the next monitoring point and repeat from step 2.
8. Record barometric pressure at the end of each event.
5 Data Evaluation
Landfill gas data will be evaluated graphically for consistency with previous results. If
exceedances are observed, then the site will initiate the Contingency Plan activities detailed
below in Section 7.
6 Contingency Plan
If allowable maximum limits for landfill gas are exceeded at the facility property boundary or in
on -site structures, the City will take the following steps:
• Step 1: Immediately take all necessary steps to ensure protection of human health and
notify NCDEQ.
• Step 2: Within seven days of detection, place the gas levels detected and a description
of the steps taken to protect human health in the operating record. In addition, landfill
gas levels shall be retested.
• Step 3: Within 60 days of detection, develop and implement a remediation plan that
describes the nature and extent of the problem and proposed remedy for the landfill gas

Winston-Salem/Forsyth County Utilities i Landfill Gas Monitoring Plan: Old Salisbury Road C&D Landfill ���
Data Reporting
releases, place a copy of the plan in the operating record, and notify NCDEQ that the
plan has been implemented.
7 Data Reporting
Data collected as a result of implementation of this plan shall be submitted to NCDEQ
electronically. The laboratory analysis output shall be provided in NCDEQ's electronic data
deliverable (EDD) format. Details of the EDD format and other documents related to reporting
requirements are provided in Appendix. An interpretation of the results shall be included in the
reports.
The reports shall be sent to:
NCDEQ Environmental Compliance
Solid Waste Section
1646 Mail Service Center
Raleigh, NC 27699-1646
7.1 Report Frequency
The monitoring report should include methane sampling, groundwater sampling and analysis
results since the last report. The report shall include recommendations for any changes that
should be made to this monitoring plan.
OSR shall retain the monitoring reports, records and supporting documentation in the facility
operating record throughout the post -closure period. These records will be made available for
review by NCDEQ personnel on request. Documentation of any contingency plan actions will
also be kept in the operating record.
