treatment facilities. The on-site personnel training and contingency plans should be also included
in the Operations Plan. Additionally, the facility must obtain an Identification Number from the
Solid Waste Section by completing the attached application form which can also be downloaded
from the following web link: https://deq.nc.gov/about/divisions/waste-management/hhw
The county does not accept Household Hazardous Waste (HHW) at the convenience center
located on the facility. Section 3.1 of the Facility Plan has been revised to remove language
indicating the collection of HHW at the facility’s convenience center.
4. (Section 4.0 of Facility Plan) Please provide the following info to this section:
i. The descriptions of the status of the on-site solar project such as the date of
construction completion, the date of initial operation, the project duration, the
operator’s contact information, the responsibilities of the County and the solar
operator etc.
A table containing the above listed information has been added to Section 4.1,
Solar Project Development, of the Facility Plan. A detailed breakdown of the
responsibilities of the County and Solar Operator is provided in the Solar
Energy leasing agreement. A copy of the leasing agreement is included in the
attachments.
ii. As-built of the solar project site such as solar panel layout, security devices,
invertors, power connections, surface drainage system, on-site infrastructures, etc.
Please find attached as-built drawings of the solar project site.
iii. According to the approved plan (DIN 25258) and the conditional approve letter
(DIN 25136) for the solar project, the County should provide the following items
in the revised Post-Closure Plan:
a. Land use of the solar project site after the project is decommissioned.
Once the solar project is decommissioned, the site will be returned to
its pre-development use. This information has also been included in
Section 2.7 of the Closure/Post Closure Plan and Section 4.1 of the
Facility Plan.
b. Descriptions of the approaches to dispose of wastes associated with the
solar project and of the responsible party (s) to determine and conduct the
project decommission.
From the Cornwall Waste Disposal Plan dated October 14, 2015,
included in the attachments, there will be no waste generated by the
operation of the solar facility.

Operations Plan
6. The ADC-Tarp info placed in Appendix 3 should be referenced in this section. Additionally, per
NCGS 130A-295.6(h1), the landfill can use an ADC that have previously been approved to use at
any sanitary landfill in the State of North Carolina. If the County intends to apply any ADC in the
approved list, please add a paragraph to this section. The approved ADC and the application
method can be found in the web link:
http://edocs.deq.nc.gov/WasteManagement/0/edoc/723214/ApprovedACM_Rev1_GDE_2017072
1.pdf?searchid=f7d5b34c-664b-4338-930a-d1db93f0272f
A paragraph stating the intended use of an approved ADC material has been added to
Section 5.1.6 of the Operations Plan.
7. The narratives of both sections may have to revised according to request from the SWS
Hydrogeologist stated in December 18, 2017 e-mail message - “Even if nothing is changed in the
WQMP and LFGMP, the County needs to submit both of those plans with new cover pages with
the current date and new PG seals with the current dates.”
The narratives of the WQMP and LFGMP were not revised because both plans have been
approved and only needed an updated PG seal. The cover pages of the WQMP and LFGMP
have been updated with the January 2018 date and new PG seals with the January 2018
dates. Please find attached both plans with revised cover pages.
8. Per NCGS 130A 295.6(h)(3), the leachate collection and removal (LCR) piping shall be cleaned
and inspected by a remote camera at least once every five years. The LCR inspection and cleaning
record must be placed in the operating record. Please add the requirements to the Section.
The above referenced language has been added to Section 9.1 of the Operations Plan.
Mr. Ming-Tai Chao, P.E.

9. The service agreement expired on January 25, 2012. The Operation Plan should discuss if the
agreement is required in the future landfill operations to execute a management plan reducing
wildlife attraction and the potential for aircraft/human safety hazard.
A new Cooperative Service Agreement was signed between Granville County and USDA
APHIS Wildlife Services on December 12, 2018. The signed agreement is provided in the
attachments. Section 2.1 of the Operations Plan has also been revised.
10. Should the Phasing Plan drawings be revised according the present in-place waste volume,
the remaining Phase 1 capacity, and the revised annual disposal rate?
The attached Drawing No. OP-03 (Phasing Plan) shows the remaining Phase 1 capacity and
the estimated annual disposal rate based on a capacity study performed in July 20, 2017. The
capacity study was performed a month prior to the permit renewal application submittal in
August 2017. As a result, we did not revise the phasing plan drawings because the drawings
show the estimated capacity and projected annual disposal rate as at the time of the August
2017 submittal. A note has been added to Drawing OP-03 to this effect.
Please do not hesitate to contact us during the review process with any additional questions
or comments you may have. We look forward to working with you to get the County’s permit
renewal approved.
Sincerely,
JOYCE ENGINEERING, INC.

1.0 INTRODUCTION AND OVERVIEW
The facility plan describes the comprehensive development of the Granville County Oxford
Municipal Solid Waste (MSW) Landfill as required by Subsection .1619 of the North Carolina
Solid Waste Management Rules. The plan includes drawings and a report that present the long-
term conceptual design for the landfill facility.
The Oxford Landfill is owned and operated by Granville County. The landfill property is located
at 6584 Landfill Road, Oxford, North Carolina, approximately 4 miles north of Oxford, North
Carolina. The facility is north of the Oxford Outer Loop between Little Satterwhite Road and
Highway 15 off of Sterl Carrington Road. The property boundary and disposal area is indicated
on an excerpt from an enlarged USGS topographic map combining the quadrangle maps of Oxford,
Stovall, Satterwhite, and Berea in North Carolina (Figure No. 1). The disposal area is located on
a slight topographic high that slopes downward in all directions. Surface water flow is towards
drainage features which eventually flow north to the Little Grassy Creek.
The existing C&D landfill (Permit No. 39-01) is on top of a closed MSW landfill covering
approximately 29 acres. The C&D landfill ceased accepting waste in December 2016, and
Granville County is currently waiting on the Closure Plan approval to initiate bidding and closure
construction activities to officially close the landfill. The MSW facility consists of 3 Units and
approximately 157.8 acres. Currently, Unit 2, Phase 1 of the MSW landfill is active. The Subtitle
D lined facility provides MSW disposal capacity for Granville County.
2.0 FACILITY DRAWINGS
2.1. Site Development
The Site Development Plan is presented on Drawings No. FP-01 and FP-02. Drawing No. FP-01
shows the property boundaries, limits of the existing waste disposal areas, limits of the proposed
waste disposal areas, the existing environmental monitoring system, the landfill entrance road,
landfill access and perimeter roads, scalehouse and office, and the convenience center. Current
topography for the property is shown, as well as the 300-foot buffer from the property line and
other site features.
In addition to showing many of the site features on Drawing No. FP-01, Drawing FP-02 shows the
phase limits of the proposed disposal areas for Units 2, 3, and 4 as well as the proposed location
for the leachate force main and storage facility.
Section II - Site Suitability, of the original Permit to Construct application prepared by Joyce
Engineering in June 2009, and revised in January 2012, details compliance with location
restrictions such as wetlands and floodplains. If future development involves the relocation of
streams or the construction of stream crossings, these may be authorized by Nationwide Permit
Nos. 26 and 14, respectively. At present, no stream channels on the property are proposed to be
relocated, and no stream crossings are planned. If the subsequent design of future phases involves
Section III - Facility Plan 2 Joyce Engineering, Inc.
Oxford MSW Landfill Permit Renewal June 2009, Revised January 2012
Granville County, North Carolina Revised August 2017, Revised January 2019
the relocation of streams or the construction of stream crossings, the plans will be forwarded to
the Corps of Engineers for review and approval.
The landfill property is located within the area shown on Flood Insurance Rate Map Panel No.
3720191500J, Community No. 37077C, issued by the Federal Emergency Management Agency,
effective date June 4, 2007. The property is outside the limits shown on the map for special flood
hazard areas inundated by the 100-year flood. Additionally, it was confirmed that the landfill is
outside the radius of concern regarding airports. A portion of the North Carolina aeronautical chart
that shows the project site and surrounding area is included as Figure 2.
2.2. Landfill Construction
Drawings No. FP-03, and FP-04 depict on-site grading activities relating to the construction and
operation of the proposed MSW landfill facility. Base grades for the development in relation to
seasonal high groundwater and bedrock are shown on Drawing No. FP-03. Base grades are
designed to be a minimum of four feet above groundwater and bedrock. Additional information
and drawings related to groundwater and bedrock can be found in the original Permit to Construct
Application Volume 3, Hydrogeologic Report, submitted by Joyce Engineering in June 2009,
revised in January 2012. Drawing No. FP-04 shows final grades which were developed for fill
slopes of 3 horizontal to 1 vertical (3H:1V). Drawing FP-04 includes proposed features for facility
closure.
2.3 Landfill Operation
Drawing No. FP-05 includes the general drainage grade and flow direction for the leachate system
and pipelines to the leachate management facility.
Phasing for the facility is included on Drawings No. FP-06 through FP-10. The phasing plans
include transitional contours for each phase of development and the location of stormwater
segregation features. Stormwater control features are included in the Erosion and Sediment
Control plans and Engineering Plan (included with the original Permit to Construct prepared by
Joyce Engineering in 2009, revised in January 2012).
3.0 FACILITY REPORT
3.1 Waste Stream
Types of Waste Specified for Disposal: The facility will accept residential, commercial, and
industrial waste, wastewater treatment sludges, and construction and demolition (C&D) debris for
disposal. Hazardous waste as defined within 15A NCAC 13A, polychlorinated biphenyls (PCBs)
wastes as defined in 40 CFR 761, and liquid waste will be prohibited from disposal in the landfill
nor will it be accepted at the convenience center. Liquid waste is defined as any waste material
that is determined to contain “free liquids” as defined by Method 9095 Paint Filter Liquids Test
(SW-846), unless the waste is household waste other than septic waste, waste oil, leachate, or gas
condensate derived from the landfill. Waste acceptance is further discussed in the Operations Plan.
Section III - Facility Plan 3 Joyce Engineering, Inc.
Oxford MSW Landfill Permit Renewal June 2009, Revised January 2012
Granville County, North Carolina Revised August 2017, Revised January 2019
Disposal Rates and Estimated Variances: Table 1 presents the Oxford Landfill’s annual MSW
disposal quantities for FY2013 through FY2017. As indicated in the table, MSW annual disposal
quantities have increased annually since the landfill started accepting waste in May 2013 from
3,006 tons in FY2013 to 48,966 tons in FY2017. Granville County ceased accepting C&D waste
in Unit 1 in December 2016. As of December 2016, all C&D waste is being disposed in Unit 2,
Phase 1 of the MSW landfill.
For planning purposes, the base annual waste stream in FY2018 is assumed equal to 48,966 tons
(194 tons per day, assuming a 5 day workweek TPD5 and seven observed annual holidays), the
quantity received in FY2017. A steady growth rate of 2% per year has been assumed to represent
the change in the waste stream over the future life of the facility. Using this growth rate, the
projected disposal rate per year and cumulative totals of each Phase are given for Units 2, 3, and
4 in Tables 2, 3, and 4.
Facility Service Area: The area to be served by the facility includes Granville County, including
without limitation the municipalities of Oxford, Butner, Creedmoor, Stem, and Stovall. The
surrounding counties of Durham, Franklin, Person, Vance, and Wake will also be served by the
facility. According to US Census Bureau, the 2016 estimated population of Granville County is
59,031 and the combined population of the aforementioned surrounding counties is 1,573,476.
Waste Management Procedures: The following procedures are in use at the existing MSWLF unit.
During operating hours, traffic is routed from the entrance gate to the scalehouse along a paved
road. From the scalehouse, traffic is routed to a gravel road leading to the disposal area. Employees
at the landfill are trained in the safety procedures for handling and detection of unapproved waste.
The screening of unacceptable waste is done through the random checking of incoming loads by a
landfill employee at the scalehouse and at the active tipping area. When unacceptable waste is
detected at the scalehouse, the load is rejected and not permitted into the landfill. If unapproved
waste is found at the tipping area, identification of the truck or persons is made (if possible) and
documented. The waste is then identified and placed into an appropriate container and taken to a
facility specifically approved to accept that type of waste for proper disposal. When this occurs,
the event is reported to the appropriate authorities.
A convenience center is located near the scalehouse. This facility enables residential users to
dispose waste without having to drive to the working face of the landfill. White goods are collected
in a separate area southwest of the landfill, and are removed by a metal recycling contractor, which
is handled through a bid process. Tires are disposed of by customers onto the ground in the
designated tire disposal area as shown on Drawing No. FP-02. At the end of each work week,
usually Friday (but no more than 10 days), landfill personnel load the tires into an open-top trailer
located adjacent to the tire disposal area. Granville County contracts with a private hauler
(currently Central Carolina Holdings) to transport the tires to Cameron, North Carolina. The
following materials are collected for recycling at the landfill: old corrugated cardboard, newspaper,
motor oil, vegetable oil, antifreeze, clear and brown glass containers, HDPE and PET plastics,
aluminum cans, steel cans, and scrap steel. The approximate locations of these features are
indicated on Drawing No. FP-02.

Granville County, North Carolina Revised August 2017, Revised January 2019
Equipment Requirements: The Oxford landfill personnel will maintain on-site equipment required
to perform the necessary landfill activities. Periodic maintenance of all landfilling equipment will
either be performed on-site or at designated maintenance facilities outside of the landfill. A list of
the equipment on site is provided in the following table. Please note that equipment type and
quantity may fluctuate based on incoming waste and equipment maintenance needs.
Type Status Quantity
Compactor (826 D) Active 1
Compactor (3-55 Rex) Backup 1
Dozer Active 4
Excavator Active 2
Loader Active 2

Motor Grader Active 1
Tractor Active 1
Water Truck Active 1
Pickups Active 3
Lowboy Active 1
Terex Truck Active 1
TS-14 Pan Active 1
Assuming the growth rate discussed above, the average waste stream would grow to approximately
210 tons per day by the time the storage capacity of the landfill nears depletion at the end of Unit
2, Phase 1 (approximately 5 years). During the operational life of the facility, equipment needs
will be reviewed annually, and additional equipment purchased or leased as needed. New
equipment will be phased in as older equipment is retired.
3.2 Landfill Capacity
Landfill capacity, by phase, was calculated using airspace volumes obtained using AutoDesk
Civil3D/Survey software. The data and assumptions used are consistent with the disposal rates
discussed in the preceding section, and are representative of the operational requirements and
conditions anticipated for the new facility.
Operating Capacity: The operating gross capacities, by Unit and Phase, are shown in Tables 2, 3,
4, and listed below. The estimated remaining operating life of the facility is approximately 75
years.

Soil Resources: The soils required to construct and operate the proposed landfill will be obtained
from on-site borrow sources. The soils removed from the on-site borrow area will be used for
structural fill, unclassified fill, periodic cover, and/or final cover. The in-place ratio of waste to
soil used to calculate the operating soil requirements was assumed to be 7 to 1, based on the
findings of capacity studies conducted for the facility. This assumes an operating plan designed
to minimize soil usage, and use of an alternate daily cover. The on-site soil resources, usage, and
balances are shown by Unit in Table 5 with Unit 2, Phase 1 detailed for this permit application.
The deficit of soil during the operation, construction, and closure of Unit 2 Phase 1 is
approximately 52,995 cubic yards. Based on the conceptual design volumes for Units 2, 3, and 4,
the total soil deficit over the life of the facility is approximately 2,089,032 cubic yards. The
property totals 397.73 acres in size with 157.8 acres permitted for landfill use (the C&DLF on top
of the closed MSWLF –Unit 1 is approximately 29 acres and is no longer accepting waste. The
waste footprints of the Subtitle D MSWLF – Unit 2, Unit 3, & Unit 4 encompass 157.8 acres). The
deficit can be satisfied by borrowing soil from other locations within the limits of the facility
property.
3.3 Containment and Environmental Control Systems
Base Liner Systems:
The proposed liner system will consist of the following components from top to bottom:
x 24-inch granular protective and/or drainage layer;
x Non-woven geosynthetic cushion;
Section III - Facility Plan 6 Joyce Engineering, Inc.
Oxford MSW Landfill Permit Renewal June 2009, Revised January 2012
Granville County, North Carolina Revised August 2017, Revised January 2019
x 60 mil high density polyethylene (HDPE) textured geomembrane;
x Geosynthetic clay liner (GCL); and
x 18-inch compacted soil layer having a permeability no greater than 1x10-5cm/sec.
Leachate Management System:
The leachate collection and removal system (LCRS) is designed to meet the requirements of the
North Carolina Solid Waste Management Regulations. The LCRS will include the following
components:
x Drainage layer;
x Leachate collector and header pipes;
x Leachate storage tank.
Leachate will be conveyed through the drainage layer consisting of at least 24 inches of free-
draining granular material. Within the drainage layer, a network of perforated collector pipes will
intercept the leachate, conveying the leachate by gravity to the leachate header pipe. The header
pipe will discharge to a sump at the downgradient end of the landfill cell. Cleanouts will be
provided for all leachate collector lines and leachate header pipe to provide access for video
inspection and cleaning of the pipes. Leachate will be pumped from the sump to an on-site storage
tank. Leachate from the tank will be periodically transported by tanker truck to the local
wastewater treatment plant. More details on the leachate collection system are included in Volume
2 - Engineering Plan of the original Permit to Construct application prepared by Joyce Engineering
in June 2009 and revised in January 2012.
Cap System:
The cap system is described from bottom to top in the following paragraphs.
Subgrade: Additional soil will be placed as needed over the 12 inches of intermediate cover to
provide a uniform base for construction of the final cap.
Gas Collection Layer: A geonet composite (geonet with geotextile fabric heat-bonded to both
sides) will be placed directly on the intermediate cover. The geonet composite will serve as a
migration zone for the lateral movement of landfill gas. The geotextile component will prevent the
migration of soil into the geonet so that gas migration will not be impeded.
Infiltration Barrier: A composite infiltration barrier will consist of a textured 40 mil flexible
membrane cap (FMC) placed on top of an 18-inch low-permeability soil layer compacted to
achieve a hydraulic conductivity no greater than 1 x 10-5 cm/sec. The 18-inch low permeability
soil layer may be replaced with a geosynthetic clay layer (GCL), as discussed in the Engineering
Plan. The low-permeability soil layer, or the GCL, will lie directly above the gas collection layer.
The FMC will consist of a linear low-density polyethylene (LLDPE) or PVC membrane.
Section III - Facility Plan 7 Joyce Engineering, Inc.
Oxford MSW Landfill Permit Renewal June 2009, Revised January 2012
Granville County, North Carolina Revised August 2017, Revised January 2019
Drainage Layer: A geonet composite will be placed directly on top of the flexible membrane cap.
The geonet will promote drainage away from the infiltration barrier and towards the perimeter
ditches. It will also help to protect the FMC from puncture.
Erosion Control Components (Protective Layer and Erosion Layer): A protective layer consisting
of at least 18 inches of local soil will be placed on top of the drainage layer. A layer of topsoil
material or organically amended local soil at least 6 inches in thickness will be placed on top of
the protective layer. The erosion and protective layers will not be heavily compacted so that
vegetative growth will be promoted. Soil tests will be conducted prior to seeding to determine if
amendments to the soil are needed to establish a healthy stand of vegetation.
Vegetative Cover: After placement of the erosion layer, the area that has been closed will be seeded
with a grass mixture. Mulch and erosion control matting will be used as needed to further minimize
erosion.
Gas Management System:
To protect public health and safety in the vicinity of the landfill, landfill gas produced by the
decomposition of refuse will be controlled and monitored during the operational, closure, and post-
closure periods. A gas management plan and gas monitoring program will be implemented for the
purpose of maintaining the concentration of methane gas below the following regulatory levels:
x The concentration of methane gas generated is not to exceed 25 percent of the lower
explosive limit (LEL) for methane in on-site structures (excluding gas control or recovery
system components); and
x The concentration of methane gas is not to exceed the LEL for methane at the facility
property boundary.
Landfill gas is a by-product from the decomposition of organic waste in a sanitary landfill. The
major components of landfill gas are methane and carbon dioxide. Other gases, such as volatile
organic compounds, are present in trace quantities. The landfill gas is proposed to be managed by
a passive gas collection system. The gas may be recovered in the future with an active system if
generation rates are sufficient to justify the additional costs.
Gas monitoring will be conducted during the active life of the landfill and throughout the closure
and post-closure periods. At a minimum, quarterly monitoring of explosive gases will be
conducted at all gas detection probes and in structures at the landfill. If additional structures are
built, the monitoring program will be expanded to include the new structures. Gas detection probes
will be installed around the boundary of the waste disposal unit. Probes should not be needed
where site topography permits gas to be released to the atmosphere before it migrates to the

3.4 Special Engineering Features
Stormwater Management System:
Unmanaged stormwater can contribute significantly to the amount of leachate collected, stored
and treated. High intensity storms can cause temporary flooding and hinder operations in active
cells. To minimize these effects, features will be provided to segregate stormwater and leachate
during operation of the MSWLF units. Within each landfill phase, a temporary system consisting
of a rainflap, berms, and/or one or more pumps and hoses will be used to divert uncontaminated
stormwater from coming into contact with waste and entering the leachate collection system.
Inactive areas will have temporary berms constructed to allow uncontaminated runoff to pond at
the downgradient end of the segregated area. The uncontaminated stormwater will be pumped or
siphoned from the impoundment area to a drainage ditch that flows to an on-site sediment basin.
The diversion will prevent the burden and added expense of having to collect, store, and treat the
additional volume of rainwater that would otherwise have become leachate through contact with
waste. As filling progresses from one subcell to the next, the berms will be removed. Waste will
be placed on the drainage layer, continuing until the capacity of the subcell has been depleted and
the opening of a subsequent subcell is required.
4.0 SOLAR PROJECT
4.1. Solar Project Development
The approximate limits of the solar project is shown on Drawings No. FP-01 through FP-05.
Drawing No. FP-01 shows the property boundaries, limits of the existing waste disposal areas,
limits of the proposed waste disposal areas, the existing environmental monitoring system, the
landfill entrance road, landfill access and perimeter roads, scalehouse and office, convenience
center, and the solar project. Current topography for the property is shown, as well as the 300-
foot buffer from the property line and other site features. The following table outlines details
provided by Granville County related to the on-site project.
Date of Construction Completion 2/13/2017
Date of Initial Operation 11/23/2016
Project duration Approximately 14 months

The solar project is located at the southwest end of the property as shown on Drawing No. FP-01.
The solar project is surrounded by a fence to prevent illegal trespassing. The white goods
containers are placed northeast of the solar project, outside the fenced solar farm parameters. White
goods are removed by a metal recycling contractor, which is handled through a bid process. Tires
are disposed of by customers onto the ground in the designated tire disposal area as shown on

Granville County, North Carolina Revised August 2017, Revised January 2019
Drawing No. FP-01. From the Cornwall Waste Disposal Plan, dated October 14, 2015, operation
of the solar project will not generate waste.
Once the solar project is decommissioned, the solar array system will be removed from the solar
farm area and the area will be reverted to its pre-development use. Prior to the solar project, the
County used the solar farm area to receive, process, and temporarily stockpile yard waste and land
clearing debris, and to conduct active composting activities. Additionally, the solar farm area was
used as a soil-borrow area to meet the facility soil needs. Due to the solar project, the County had
to relocate the composting area and yard waste and land clearing debris area to Unit 2, south of
Phase 1. Moreover, Unit 2 is now being used to serve as a soil-borrow area to sustain the site soil
needs instead of the solar farm area. The new locations for displaced municipal solid waste
management units are within the landfill property (Drawings No. FP-01 through FP-05). Finally,
the County discontinued the disposal of animal carcass in the solar farm area in 2013.

Granville County, North Carolina Revised August 2017, Revised January 2019
1.0 GENERAL
The Operation Plan describes how the design and construction plans will be implemented during
the life of the facility. The plan consists of drawings and accompanying text which illustrate
existing conditions, cell progression, waste placement and daily operations, leachate management,
special waste management, buffer zones and soil borrow procedures.
The Oxford Landfill is owned and operated by Granville County. The landfill property is located
at 6584 Landfill Road, Oxford, North Carolina, approximately 4 miles north of Oxford, North
Carolina. The facility is north of the Oxford Outer Loop between Little Satterwhite Road and
Highway 15 off of Sterl Carrington Road. The disposal area is located on a slight topographic
high that slopes downward in all directions. Surface water flow is towards drainage features which
eventually flow north to the Little Grassy Creek.
The area to be served by the facility includes Granville County and the surrounding counties of
Durham, Franklin, Person, Vance and Wake. The municipalities of Oxford, Butner, Creedmoor,
Stem and Stovall will also be served. The intent of this facility is to accommodate waste from
Granville County and minor overflow waste from the surrounding counties. Therefore, waste
generation trends solely from Granville County were used to develop projected disposal rates.
The landfill property is approximately 397.73 acres. The site consists of an existing C&D landfill
(Permit No. 39-01) on top of a closed MSW landfill covering approximately 29 acres, and an
existing MSW Landfill (Unit 2, Phase 1) covering approximately 11 acres. Granville County
ceased accepting C&D waste in Unit 1 (C&D Landfill) in December 2016. Other areas at the
facility include a convenience center, collection of scrap tires, and white goods for off-site
recycling or disposal. Ancillary facilities such as a scale house and maintenance building are also
located on the site. The MSW facility consists of 3 Units (157.8 acres). Unit 2 contains 5 phases,
Unit 3 contains 11 phases, and Unit 4 contains 2 phases. This application is for a renewal of the
Permit to Operate Unit 2, Phase 1 of the MSW landfill.
Currently, an average of 194 tons of MSW is managed daily at the landfill, based on a five-day
week and 7 holidays, or 253 days per year. This includes the C&D waste being disposed in Unit
2, Phase 1 of the MSW landfill.
2.0 OPERATIONS DRAWINGS
2.1 Existing Conditions
The site existing conditions is presented on Drawing No. OP-01 and currently includes the
following components:
y A C&D landfill over closed unlined MSW landfill (Permit No. 39-01-1997). The C&D
landfill ceased accepting waste in December 2016, and Granville County is currently
waiting on the Closure Plan approval to initiate bidding and closure construction activities
to officially close the landfill.
y Active MSW landfill Unit 2, Phase 1 (Permit No. 39-01-2012).
y Convenience center (drop-off area for recyclables and waste).

y Office and maintenance building.
y Weighing scales.
y Tire collection area.
y White goods collection area.
y Land clearing debris collection area.
y Yard trash collection and compost area.
y Solar farm.
The drawing also shows the limits of the existing waste disposal area, the environmental
monitoring system, the landfill entrance road, landfill access and perimeter roads, scalehouse, and
office. Current topography for the property is shown, as well as the neighboring residence and
wells, the 300-foot buffer from the property line, and other site features.
Borrow areas will be located in future Units 2, 3, & 4.
The county recognizes that the surrounding wildlife needs to be protected, hence the Cooperative
Service Agreement between the USDA APHIS Wildlife Services and the County was renewed on
December 12, 2018. The new Cooperative Service Agreement is provided in Appendix 6.
3.0 GENERAL OPERATING CONDITIONS
3.1 Hours of Operation
The MSWLF will operate Monday through Friday. The operation hours are 7:30 a.m. to 4:00 p.m.,
but may be adjusted slightly due to fluctuations in the waste stream, or other unforeseen conditions.
Brush, metal, and tires are accepted Monday through Friday and 8:00 a.m. to 12:00 p.m. on
Saturday unless altered by the County Board of Commissioners. The MSWLF will be closed on
the following major holidays: New Year’s Day, Good Friday (close at 12:00 pm), Memorial Day,
July 4th, Labor Day, Thanksgiving Day, Christmas Eve, and Christmas Day. An entrance sign has
been posted noting operating hours. Holiday closings are advertised in the local paper and notices
posted at the entrance ten days prior to the holiday.
3.2 Site Access and Safety
Limiting access to the landfill facility is important for the following reasons:
x Unauthorized and illegal dumping of wasted materials is prevented;
x Trespassing, and injury resulting there from, is discouraged; and
x The risk of vandalism is greatly reduced.
Access to active areas of the landfill will be controlled by a combination of fences and natural
barriers such as the creeks. Access to the facility is controlled through one entrance along Landfill
Road, which has secure gates to prevent access after operating hours. A large sign containing the
information required in Rule .1626(6) (i.e. dumping procedures, hours, permit number, etc.) is
posted at the facility entrance. Waste collection vehicles are weighed in (and out if tare weights
are not on file for the vehicle) at the existing scale.
Operations Plan 3 Joyce Engineering
Oxford MSW Landfill Permit Renewal Rev. September 2014, Rev. November 2015
Granville County, North Carolina Revised August 2017, Revised January 2019
Signs have been posted directing traffic to separate areas for the collection of tires, white goods,
yard waste, and other recyclable goods, and the MSW active landfill area.
During the hours of operation, traffic is routed from the entrance gate and scale house via a gravel
access road to the MSWLF. The roads shall be maintained to remain passable during all weather
conditions. The cell access roads will change in location as the working face moves both
horizontally and vertically with the progression of waste fill. The slopes of cell access roads at
maximum fill heights should not exceed 10%. An attendant is on duty at the scalehouse at all times
during the operating hours.
Frequent inspections of the access roads, gates and fences will be performed by landfill personnel.
Landfill personnel will maintain the approved access road conditions, as well as, monitor the
accessibility to monitoring points. Evidence of trespassing, vandalism, or illegal operation will be
reported to the County Sheriff.
3.3 Waste Acceptance
The landfills will accept only those solid wastes included in their current permits, including
household, commercial, construction and demolition debris, land clearing and inert debris, and
industrial solid wastes. These are defined in Rule .1602 for the MSW landfill as follows:
3.3.1 MSW Landfill
x Household waste means any solid waste derived from households including single and multiple
residences, hotels and motels, bunkhouses, ranger stations, crew quarters, campgrounds, picnic
grounds, and day-use recreation areas.
x Commercial solid waste means all types of solid waste generated by stores, offices, restaurants,
warehouses, and other nonmanufacturing activities, excluding residential and industrial
wastes.
x Construction and Demolition Debris Waste means solid waste generated solely from the
construction, remodeling, repair, or demolition operations on pavement and building
structures.
x Land Clearing and Inert Debris means solid waste created during land clearing including
untreated wood, yard trash, uncontaminated soils and rock.
x Solid waste generated by mobile or modular home manufacturers and asphalt shingle
manufacturers in Granville County.
x Industrial solid waste means solid waste generated by manufacturing or industrial processes
that is not a hazardous waste regulated under Subtitle C of RCRA. Such waste may include,
but is not limited to, waste resulting from the following manufacturing processes: electric

products; textile manufacturing; transportation equipment; and water treatment. This term
does not include mining waste or oil and gas waste.
Neither spoiled food, hatchery waste, nor other animal waste is intended to be received in
quantities large enough to be problematic for operations. In the event that such wastes are received,
they will be immediately buried and covered with a thick layer of soil followed by non-putrescible
municipal solid waste. If asbestos waste is received, it will be managed in accordance with 40
CFR 61. The waste will be disposed at the bottom of the working face and covered immediately
with soil in a manner that will not cause asbestos particles to become airborne.
3.4 Prohibited Waste
A sign is posted at the landfill gate (see Section 3.2 above) that reads "No hazardous or liquid
waste accepted without written permission from the Division of Solid Waste Management". The
MSW landfill will not accept:
x Hazardous waste as defined within 15A NCAC 13A, including hazardous waste from
conditionally exempt small quantity generators;
x Polychlorinated biphenyl (PCB) wastes as defined in 40 CFR 761;
x Liquid wastes (i.e., any waste material that is determined to contain "free liquids" as defined
by SW-846 Method 9095 (Paint Filter Liquids Test), unless the waste is household waste other
than septic waste or waste oil, or leachate or gas condensate derived from the landfill managed
in accordance with Rule .1626(9);
x Barrels and drums unless they are empty and sufficiently perforated, except fiber drums
containing asbestos;
x Wooden pallets (applies to MSW landfill only);
x Discarded computer equipment and televisions (effective July 1, 2011)
x Other wastes specifically banned from landfill disposal by rule or statute for MSW landfill,
such as lead acid batteries, whole tires, used oil, oyster shells, or aluminum cans.
In addition to the prohibited waste, the landfills will not dispose of yard waste, white goods,
antifreeze, whole scrap tires, recyclable plastic and beverage containers, and motor vehicle oil
filters.
Operations Plan 5 Joyce Engineering
Oxford MSW Landfill Permit Renewal Rev. September 2014, Rev. November 2015
Granville County, North Carolina Revised August 2017, Revised January 2019
The County will notify the Division within 24 hours of attempted disposal of any waste the landfill
is not permitted to receive, including waste from outside the area the landfill is permitted to serve.
The waste screening program is described later in this Operation Plan.
3.5 Special Wastes
The facility accepts “special wastes” such as tires and white goods but separates these wastes from
the general disposal area.
Tires
Tires are received from residential and commercial customers. Tire counts are verified by
observation and/or North Carolina Tire Certification Form (for customers with 6 or more tires).
Customers are directed to the tire disposal area located north of the scale house as noted on
Drawing No. OP-01. Tires are disposed of by customers on to the ground. Weekly, the tires are
loaded into an open top trailer. The County contracts with Central Carolina Holdings for recycling
and/or disposal of the tires that are collected on-site. Central Carolina Holdings changes out the
trailer as needed with a maximum time of 10 calendar days between trailers. Tires are currently
hauled to and processed in Cameron, North Carolina.
White Goods
Customers with white goods and/or scrap metal are directed to the white goods area located north
of the scale house as shown on Drawing No. OP-01. Customers place white goods and scrap metal
in the unloading area. Freon containing devices are off loaded to the northwest corner of the pad
where a licensed contractor, Huff’s Soil Conservation, for Freon removal performs the recovery
of Freon. The contractor marks appliances that have undergone Freon removal with an “X”.
Records of Freon removal or damaged Freon lines are kept at the scalehouse. The appliance is
then stockpiled with the other metals. The metals are stored on-site until they are removed to a
recycling facility. Removal of white goods and scrap metal are usually bid out on a $/ton basis.
Market conditions and the contractor determine the scrap yard which can range from Winston
Salem, NC to Norfolk, Va. The County handles approximately 4 tons of metals for recycling per
month.
Land Clearing Debris
The County receives land clearing debris from Granville County and the surrounding counties of
Durham, Franklin, Person, Vance and Wake. The municipalities of Oxford, Butner, Creedmoor,
Stem and Stovall will also be served. Land clearing debris consists of solid waste generated solely
from land clearing activities.
The facility receives on average 45 tons of this type of waste per month. This material is stockpiled
and ground as needed. Once ground, the material is used on site for erosion control.
The land clearing debris area is located east of Unit 1 and south of Unit 2 as shown on Drawing
No. OP-01.
Operations Plan 6 Joyce Engineering
Oxford MSW Landfill Permit Renewal Rev. September 2014, Rev. November 2015
Granville County, North Carolina Revised August 2017, Revised January 2019
Asbestos Waste Management
The Oxford facility may dispose of asbestos within the MSW landfill. Asbestos will only be
accepted if it has been processed and packaged in accordance with State and Federal (40 CFR 61)
regulations. Asbestos will arrive at the site during morning operating hours in vehicles that contain
only the asbestos waste and only after a minimum 24-hour advance notification by the generator.
Once the hauler brings the asbestos to the landfill, the hauler will be directed to the designated
asbestos disposal area by operating personnel. The designated disposal area will be prepared by
operations personnel by leveling a small area using a dozer or loader. Prior to disposal, the landfill
operators will stockpile cover soil near the designated asbestos disposal area. The volume of soil
stockpile will be sufficient to cover the waste and provide any berms, etc. to maintain temporary
separation from other landfill traffic.
Once placed in the prepared area, the asbestos will be covered with a minimum of 18 inches of
daily cover soil placed in a single lift. The surface of the cover will be compacted and graded
using a track dozer or loader. The landfill compactor will be prohibited from operating over
asbestos disposal areas until at least 18 inches of cover are in place.
The landfill staff will visually record the approximate location and elevation of asbestos waste
once cover is in-place. The Solid Waste Director will then review pertinent disposal and location
information to assure compliance with regulatory requirements and enter the information into the
Operating Record. Asbestos location information is known by landfill staff and available to the
Department upon request.
Once disposal is completed, the area may be covered with waste. No excavation into designated
asbestos disposal areas will be permitted.
Recyclables
The landfill’s convenience center also collects household recyclables such as aluminum cans, steel
cans, newspaper, motor oil, vegetable oil, antifreeze, glass, PET Plastics, and cardboard.
Used oil is picked up by Noble Oil when the facility has collected 350 gallons.
The facility name, physical address, permit number (if applicable), phone number and/or email
address for current contractors being used for transporting, treating, processing, and/or disposing
of recyclable material will be maintained in the facility Operating Record.
Sludge
The landfill may accept wastewater treatment sludges in accordance with the following
conditions:
x Co-disposal with waste in a permitted MSW landfill facility; or
x Utilized as a soil conditioner and incorporated into or applied onto the vegetative growth
layer but in no case greater than six inches;
Additional information about the facility’s management of special waste can be found in the
Granville County Solid Waste Management Plan.

3.6 Litter Control
Prompt compaction of the waste at the working face will be the first method used to control
blowing litter. Temporary fences and/or dikes may be constructed to contain windblown material
during operations. In addition, landfill personnel will pick up windblown litter as necessary each
working day and return it to the working face.
3.7 Equipment
Equipment will be needed for spreading and compacting wastes, hauling, spreading and
compacting cover material, for support functions such as access road construction and
maintenance, dust control, mud control and drainage channel excavation.
The following table outlines the equipment, personnel, and working face requirements necessary
for the proper operation of the facility, based on average waste intake rates.

Each piece of equipment is matched with one or more operators to meet personnel needs over the daily operating period.
2. Equipment calculations are based on 10-hour operations and Bomag 671 Compactor (weight 70,000 lbs. min.), and CAT Track-Type
Tractor (dozer) type D-7 (55,000 lbs. min) in combination with CAT tracked loader model 973 (58,000 lbs. min.) typical.
3. In the event that operations are for other than 10 hours, equipment needs will be adjusted proportionally.
The amount of equipment on site should provide the necessary backup in the event of an
emergency situation.
3.8 Air Quality
The facility will maintain all necessary compliance with the Division of Air Quality. Open burning
of waste, including yard waste and brush, is prohibited at the landfill.
Operations Plan 8 Joyce Engineering
Oxford MSW Landfill Permit Renewal Rev. September 2014, Rev. November 2015
Granville County, North Carolina Revised August 2017, Revised January 2019
3.9 Dust, Odor, Fire and Vector Control
To minimize dust related to waste hauler traffic, road surfaces are sprayed with water from a water
truck as needed during windy, dry weather.
Odors and disease vectors will be controlled by promptly covering the waste at the working face,
and by use of the daily cover. Daily cover is described in more detail in a subsequent section.
Incoming loads of waste are observed by site operators and scalehouse attendants for evidence of
fire such as flames, smoke, or the odor of burning material. Inspections will be conducted in a
designated area near the working face of the landfill. Burning loads will be extinguished before
dumping if possible. The waste will be removed or segregated from other waste in the disposal
area. The landfill operator will perform an evaluation of the situation to determine whether the
fire can be extinguished using fire extinguishers or other equipment present at the site, or if off-
site equipment will be needed. If necessary, the local fire department will be called to render
assistance in extinguishing the fire. Fires that occur at the landfill will be reported verbally to the
Division within 24 hours and in writing within 15 days. A copy of the Fire Occurrence Notification
Form is in Appendix 7.
If a fire occurs at the waste disposal area, the operator first observing the fire will immediately
radio the landfill office to report the size of the fire and request backup. If possible, the waste will
be removed or segregated from other waste in the disposal area. Following segregation, the
situation will again be evaluated to determine whether or not additional assistance will be
necessary from off-site emergency personnel and handled as described above.
Fire extinguishers are located on each piece of equipment on site. Equipment operators are trained
annually in the use of these extinguishers. Fire extinguishers will be used for small, localized fires.
A stockpile of soil is maintained near the working face to be used for extinguishing small surface
fires that may be too large to control with the fire extinguishers carried on the landfill equipment.
Emergency personnel will be notified in the case of fires too large to be extinguished with fire
extinguishers or soil as described above. Water contained in sedimentation ponds can serve as
emergency reservoirs to aid local firefighters in the extinguishing of larger fires.
3.10 Scavenging/Salvaging
The unauthorized removal of waste, or scavenging, is prohibited at the landfill. Landfill personnel
may remove recyclable salvageable materials and process them through the County’s recycling
program.
3.11 Type 1 Composting Facility
3.11.1 Waste Quantities
The County receives yard trash from Granville County and the surrounding counties of Durham,
Franklin, Person, Vance and Wake. The municipalities of Oxford, Butner, Creedmoor, Stem and
Operations Plan 9 Joyce Engineering
Oxford MSW Landfill Permit Renewal Rev. September 2014, Rev. November 2015
Granville County, North Carolina Revised August 2017, Revised January 2019
Stovall will also be served. This waste consists of solid waste resulting from landscaping and yard
maintenance such as brush, grass, tree limbs, and similar vegetative material. The composting
facility covers approximately 1.9 acres.
Accurate records of incoming waste should be kept at the scalehouse. These records should
differentiate between loads of brush, clean wood, and loads of leaves or grass clippings.
3.11.2 Design Considerations
Design Capacities and Product Quality
The facility currently receives an average of 43 tons per year of yard trash. This material is
windrowed as received.
The following table summarizes the design criteria used to verify adequate space at the facility for
the composting operation. As a factor of safety, it was assumed that the density of the product
remains the same as the incoming waste stream.
Total waste stream (by weight) 43 tons (annual)
Density (assumed average) 500 lb/cubic yard
Composting waste stream (by volume) 172 cubic yards
Cross-section windrow 2' (top) x 15' (base) x 4' (ht) 34 square feet
Total length windrow required 10 feet
At 10' length 1 windrow needed annually
With 15' base and 10' aisle, total acreage required 0.006 acres maximum
(running 1 windrow at a time)
The site is designed with a working area for the Type 1 facility of approximately 0.15 acres as
illustrated on Drawing No. OP-01. Sufficient room is available for the operation of 2 windrows.
Site Plan
The composting facility is located north of the scalehouse. The location is shown on Drawing No.
OP-01.
3.11.3 Operations
General Description
Incoming yard trash is weighed and directed to the yard trash collection and composting area. The
yard trash is stockpiled and moved by landfill personnel into the windrow. The yard trash is
formed into windrows using a front end loader. The windrows are spaced approximately 10 feet
apart and each has a east/west orientation and the following geometry: 4 feet high x 15 feet wide
at base x 2 feet wide at top. An aisle of 25’ is maintained on the east side of the windrows for
emergency access.
Operations Plan 10 Joyce Engineering
Oxford MSW Landfill Permit Renewal Rev. September 2014, Rev. November 2015
Granville County, North Carolina Revised August 2017, Revised January 2019
Once the windrow is formed, it will be turned several times using a front end loader to mix the
materials. If necessary, water will be added as the windrow is constructed and then periodically
during the stabilization process. The pile will be sprayed as it is turned on an as needed basis. For
optimum composting the moisture should be maintained between 45% and 60%. Dryer than 45%
and the microbial action is slowed; higher than 60% and the material becomes difficult to handle
and difficult to aerate.
The temperatures are taken at a minimum of each third (3 separate places) of the windrow. It is
suggested that the temperature be controlled by turning (aerating) to assure that the compostable
material is maintained at an optimum range for decomposition (between 104oF and 113oF) and
then allowed to elevate to 131oF where it must be maintained for a period of 3 consecutive days
as required by Rule .1406(10). When the temperature within the windrow falls below 120oF –
130oF during the final stages of composting, the windrow is turned. Windrow construction and
turning frequency will be sufficient to maintain aerobic conditions to produce a compost product
in the desired time frame. Separate records are kept for each windrow. Once a windrow is
constructed, it is assigned an I.D. number and folder which are used over the lifespan of the
windrow. Every time windrow data is taken, it is documented and logged in the folder.
A nitrogen source may be added to the yard waste as needed to promote the compost process. The
County uses calcium nitrate when necessary. The calcium nitrate is spread by hand and
mechanically mixed.
The process of stabilization is expected to take 3 days. The final time frame is a function of
material density, material type, moisture and operational controls.
Once the windrow begins to cool indicating stabilization, the County screens the material and the
larger particles are reused in the process or used as woodchips or mulch. By keeping the coarser
materials in the compost, it enables more oxygen to get into the windrows and produces more
compost in the finished product. The compost is now stockpiled. Depending on the end use
requirements, the compost may be screened again prior to stockpiling if a finer screen is available.
The larger particles would be either reused in the process or used as a coarser product.
If the material is free of sharp particles, has no offensive odor, and has minimal pathogens, it may
be used in an unrestricted way.
Once the compost meets the regulatory requirements for distribution to the public, it can be
released for use. As the public obtains the material they must be given the information indicated
in Section 3.11.8.
3.11.4 Waste Acceptance Rule .1406 (6)
The Type 1 compost facility will accept only grass, leaves, brush, tree limbs, and similar vegetative
material. No municipal solid waste (MSW), hazardous waste, asbestos containing waste, land
clearing debris, or medical waste shall be accepted at the facility. The County accepts yard trash
in a non-bagged state or in approved biodegradable bags. Deliveries are monitored at the site. The
County anticipates little contamination of the material.
Operations Plan 11 Joyce Engineering
Oxford MSW Landfill Permit Renewal Rev. September 2014, Rev. November 2015
Granville County, North Carolina Revised August 2017, Revised January 2019
3.11.5 Monitoring Requirements Rule .1406 (9)
The windrows are monitored for temperature daily. A log will be kept of all temperature readings,
which includes the location of the probes. A copy of the temperature log is contained in Appendix
4.
Moisture should be kept in the range of 45% - 60%. Water should be added as required to stay
within this range. Temperature will be monitored daily until readings of 131°F are achieved for
three (3) consecutive days. To monitor temperature, the probe should be inserted 12"- 24" every
50' along the windrow at a 45° - 90° angle.
3.11.6 Temperature Parameters Rule .1406 (10)
For Type I facilities, the compost process must be maintained at or above 55°C (131°F) for 3
consecutive days and aerated to maintain elevated temperatures.
3.11.7 Addition of Nitrogen Bearing Materials Rule .1406 (13)
Nitrogen compounds may be added as necessary to adjust the nutrient balance for optimum product
development. Only approved waste materials (i.e. grass clippings, leaves) or chemical compounds
may be added. Nitrogen rich materials can decompose rapidly and cause odor problems. Materials
such as grass clippings must be incorporated into the process as soon as possible.
To determine if nitrogen is necessary, the carbon to nitrogen ratio should be calculated. For proper
composting, this ratio should be greater than 25:1, but less than 40:1 at the start of composting.
Incoming materials have the following estimated ratios:
x Grass clippings 12 - 15:1 x Dry leaves 40:1 x Paper and wood 200:1 x Sawdust 200 - 500:1
Thus, adjustment may be necessary after grinding, screening and blending the feedstock materials.
3.11.8 Classification/Distribution of MSW Compost Products Rule .1407
Requirements
For unrestricted use, the finished Type I compost must meet the following criteria:
x Minimal pathogenic organisms
x Free from offensive odors x Containing no sharp particles x Man-made inerts do not exceed 1 inch in size
Operations Plan 12 Joyce Engineering
Oxford MSW Landfill Permit Renewal Rev. September 2014, Rev. November 2015
Granville County, North Carolina Revised August 2017, Revised January 2019
If these criteria are met then the finished compost material will be marketed to residents of the
County and surrounding areas with directions provided.
Labeling
When the Type 1 compost material is to be marketed to the public, sufficient information should
be provided to the public to:
x Inform users of the benefits of using compost
x Advise users on suggested uses of product
x Inform users of cautions in using product
x Inform users of composition of the material including nutrients and contaminants
x Inform users of source of feedstock
Appendix 5 includes samples of informative brochures that may be provided to the end user.
4.0 RANDOM WASTE SCREENING PROGRAM
4.1 Authority
The following “Random Waste Screening Program” has been developed in accordance with North
Carolina's Solid Waste Management Regulations, Rule .0544(e) and .1626(1)(f) for the landfill.
The program is primarily used to detect hazardous waste that is mixed with waste. However, the
same methodology can be used to keep hazardous wastes and prohibited wastes out of the landfill.
Key elements addressing waste screening are as follows:
No hazardous or liquid wastes as defined in 15A NCAC 13A, municipal solid
waste, or materials offering an undue hazard to landfill personnel or the landfill
operations shall be accepted at the landfill except as specifically authorized by the
facility permit or by the Division. The owner or operator has implemented an
inspection program to detect and prevent disposal of unpermitted wastes, hazardous
and liquid wastes, and polychlorinated biphenyls (PCB). This program includes, at
a minimum:
y Random inspections of incoming loads, unless the owner or operator takes other steps
to ensure that incoming loads do not contain municipal solid waste, regulated hazardous
or liquid wastes, or PCB wastes;
y Records of any inspections;
y Training of facility personnel to recognize municipal solid waste, regulated hazardous
or liquid wastes, or PCB wastes; and
y A contingency plan to properly manage any identified unpermitted or hazardous and/or
liquid wastes.
Operations Plan 13 Joyce Engineering
Oxford MSW Landfill Permit Renewal Rev. September 2014, Rev. November 2015
Granville County, North Carolina Revised August 2017, Revised January 2019
4.2 Random Selection
Random selection of vehicles to be inspected will be conducted on a regular basis, depending on
personnel available. At least one vehicle per week, but not less than one percent by weight of the
waste stream (based on the previous week’s total) will be randomly selected at the working face
by the personnel conducting the inspection. A random truck number and time will be selected
(i.e., the tenth load after 10:00 a.m.) on the day of inspections.
4.3 Record Keeping
Report forms for record keeping purposes are included in Appendix 1. These forms will be
completed at each inspection. All reports and resulting correspondence will be maintained at the
County Landfill office for the life of the landfill and during the post-closure period.
4.4 Training
The Landfill Operations Manager and/or staff from the Department of Solid Waste who are trained
to identify and manage MSW waste and hazardous and liquid waste will supervise inspections.
Landfill operators, recycling attendants, and landfill clerks responsible for screening waste will be
properly trained to identify hazardous and liquid waste.
4.5 Inspection Site Location
Inspections will be conducted in a designated area near the working face of the landfill.
4.6 Action Plan
The following action plan details the procedure to follow for conducting the random waste
inspections.
1) Dump single load in prepared area. Detain truck and driver until inspection is completed.
2) Spread waste with compactor and/or hand tools as appropriate. Hand rake loads that
include items such as large closed containers to avoid possible rupturing of the containers. Have
appropriate safety equipment present. Minimum safety equipment will include:
x Rubber gloves;
x Rubber boots;
x Safety glasses; and
x Long handled hoe
3) Examine waste for excluded waste and/or safety hazards:
x Containers labeled hazardous;
x Excessive or unusual moisture;
Operations Plan 14 Joyce Engineering
Oxford MSW Landfill Permit Renewal Rev. September 2014, Rev. November 2015
Granville County, North Carolina Revised August 2017, Revised January 2019
x Regulated biomedical (red bag) waste;
x Powders, dusts, smoke, vapors, or chemical odors;
x Sludges, pastes, slurries, or bright colors (such as dyes); and
x Unauthorized out-of-County waste
4) Take appropriate action(s) as follows:
x Incorporate acceptable waste into working face. Facility personnel, especially the landfill
operator and scalehouse attendant, should be familiar with the acceptable and unacceptable
waste materials and the control measures necessary to prevent unacceptable wastes from
being disposed of at this facility.
x Hold suspect waste for identification by on-site personnel and, if necessary, confirmation
by others such as a contract laboratory, hazardous waste management firm, or state and/or
federal regulator;
x Interview driver and hauler to identify the source of suspect waste in the load;
x Hold rejected hazardous or liquid waste for generator; and
x Arrange for hazardous or liquid waste collection by a collector licensed to store, transport,
and dispose of hazardous waste according to federal and state requirements.
5) Document Actions:
x Record Inspection;
x Retain Reports; and
x Report hazardous, liquid or PCB wastes to Solid Waste Section – NCDEQ. A verbal notice
to the Division within 24 hours and a written notice shall be submitted within 15 days.
In the event hazardous, liquid, and/or PCB wastes is placed on the working face. The hauler will
be retained and requested to remove the waste from the facility. However, if the hauler is unable
to be retained or identified the landfill operator will immediately act to contain the area. A
hazardous waste management firm will be contacted to remove and properly dispose of the waste.
5.0 SUBCELL PROGRESSION AND WASTE PLACEMENT
5.1 MSW Landfill
5.1.1 Subcell Progression
The method of filling shall be the area method in accordance with the previously submitted and
approved plans. Phase 1 was constructed with stormwater segregation features to limit the potential
of stormwater runoff to become leachate.
Future phases inactive areas will be separated from the active area by the use of a temporary berms
and a rainflap to segregate the uncontaminated runoff. Stormwater will be removed from the cell
with electric and portable pumps and placed into a drainage area leading to sediment basin SB-4
located north of Unit 2. As filling progresses to the remaining Phase area, the rainflap and berms
Operations Plan 15 Joyce Engineering
Oxford MSW Landfill Permit Renewal Rev. September 2014, Rev. November 2015
Granville County, North Carolina Revised August 2017, Revised January 2019
will be removed. The date of the rainflap and berm removal will be documented and kept with the
facility’s operating records.
5.1.2 Waste Placement and Compaction
The waste will be tipped in the active area as closely as possible to the working face, and pushed
if necessary to the desired area. The length of the daily working face will be maintained at
approximately 100 feet in order to provide adequate space for several trucks to dump at the same
time. The width of the working face varies somewhat depending on the rate of waste acceptance
on a given day, weather conditions and other factors, but should be maintained as small as possible.
The waste shall be compacted as described below with steel-wheeled compactors (see equipment
list earlier in section 3.7).
To minimize the chance of damage to the liner in any new subcell, the initial lift of waste will be
at least 5 feet thick, and will consist of only residential, non-bulky waste. Compaction will be
minimal because later lifts will surcharge the initial lift so that there is no net loss of density.
Typical compaction procedures above the initial lift will involve placement of waste in thin layers
(1-2 feet thick) on 4H:1V slope and not to exceed 3H:1V. The compactor will roll a minimum of
three times across the waste. The compaction effort will extend slightly past the waste to prevent
wind-blown material leaving from the edge of the lift. Calculations have determined that the
approximate in-place density of waste and soil combined is around 1,000 pounds per cubic yard.
The waste density calculation will be reviewed periodically. Operational procedures may be
revised to improve the efficiency of the site.
5.1.3 Filling Operations
The waste will be compacted according to the procedures described above. Each lift of waste shall
be approximately 10 feet thick, including an allowance for weekly cover. The proposed waste to
total soil volume ratio is approximately 7:1. The size of the working face will be maintained as
small as possible. The width of the working face will vary, depending on the rate of waste
acceptance on a given day and weather conditions.
5.1.4 Daily Cover
At the end of each day's operation, compacted waste in the subcell will be covered with a tarp
using two bulldozers and two men. Every Friday, a minimum of six inches of soil is used to cover
the waste. The cover soil shall be compacted with minimum of two passes with the compactor.
Waste may be covered more frequently than once per day if necessary to control fires, odors, or
blowing litter.
5.1.5 Intermediate Cover
In areas where another lift of waste will not be placed for at least 12 months, an additional 6 inches
of soil shall be placed over the daily cover for a total of 12 inches of intermediate cover. Provisions
Operations Plan 16 Joyce Engineering
Oxford MSW Landfill Permit Renewal Rev. September 2014, Rev. November 2015
Granville County, North Carolina Revised August 2017, Revised January 2019
for a vegetative ground cover sufficient to restrain erosion shall be accomplished within 30
working days or 120 calendar days following completion of each phase of development.
5.1.6 Alternate Cover Material
Granville County plans to use a synthetic tarp, an approved alternative daily cover (ADC) material
listed in the Solid Waste Section’s Document # 723214, as the ADC for the active area of the
landfill. The synthetic tarp will consist of high density polyethylene tapes coated on each side with
a low density polyethylene. The specifications of the ADC-Tarp are provided in Appendix 3 of
this section. The tarp will be applied by hand or landfill equipment.
6.0 ENVIRONMENTAL MONITORING PROGRAMS
6.1 Water Quality
The Water Quality Monitoring Plan for the MSW Landfill was prepared by Joyce Engineering in
June 2009. A more recent Water Quality Monitoring Plan for the Oxford Landfill Unit 1 was
prepared by Joyce Engineering and submitted to NCDEQ in May 2014.
6.2 Landfill Gas
The Landfill Gas Monitoring Plan for the facility was submitted by Joyce Engineering to NCDEQ
in August 2014.
7.0 EROSION AND SEDIMENT CONTROL REQUIREMENTS
Erosion and sediment control features have been designed in accordance with all applicable
requirements, as will all future structures. The erosion and sediment control features will prevent
silt from leaving the facility, as well as, prevent excessive on-site erosion. As required, the facility
will be operated in a manner which will not cause a discharge of pollutants into waters of the
United States, including wetlands, that violates any requirements of the Clean Water Act,
including, but not limited to, the National Pollutant Discharge Elimination System (NPDES)
requirements, pursuant to Section 402. The facility will not cause the discharge of a nonpoint
source of pollution to waters of the United States, including wetlands, that violates any requirement
of an area-wide or State-wide water quality management plan that has been approved under Section
208 or 319 of the Clean Water Act, as amended.
Surface water shall be diverted from the operational area and shall not be impounded over or in
waste. Drainage structures and embankment slopes are regularly inspected for erosion, and
maintained as needed. The vegetation on the slopes is mowed at least once a year. These slopes
are maintained with reseeding, fertilizer, and other means, as necessary, to promote a healthy stand
of vegetation.

9.0 LEACHATE MANAGEMENT PLAN FOR UNIT 2, PHASE 1 MSW LANDFILL
9.1 Maintenance of the Leachate Collection System
The operator will conduct weekly inspections of the leachate collection and storage system. The
weekly inspection will consist of inspecting the forcemain and its appurtenances, overfill
prevention equipment, the truck filling station, and the exterior of the tank for leaks, corrosion,
and maintenance deficiencies. If there are any deficiencies, remedial measures will immediately
be taken to correct the deficiencies. At least once every five years, the leachate collection and
removal (LCR) piping shall be cleaned and inspected by a remote camera. The LCR inspection
and cleaning record will be placed in the operating record. Inspection reports will be maintained
and made available throughout the lifetime of the storage system. Leachate levels in the storage
tank will be monitored daily and recorded. Cleanouts are provided to allow access to the leachate
collection system. In accordance with state law, water under pressure and mechanical methods
through these cleanouts are periodically used as preventive maintenance of the piping system.
Only certified explosion-proof equipment will be used for video inspections in accordance with
OSHA requirements. Maintenance needs will be re-evaluated if there is an unexpected change in
leachate production rates.
9.2 Leachate Generation Records
The volume of leachate in the tank is monitored daily. Flow meters in the side slope riser and the
pumping station will be used to record daily flows. Leachate is anticipated to be hauled at least
Operations Plan 18 Joyce Engineering
Oxford MSW Landfill Permit Renewal Rev. September 2014, Rev. November 2015
Granville County, North Carolina Revised August 2017, Revised January 2019
once a week from the facility. The frequency may change depending on the amount of leachate
generated, but per the agreement with City of Oxford, the monthly average amount of leachate
disposed of cannot exceed 15,000 gallons per day. The County maintains records of leachate
hauled from the leachate tank at the landfill to a wastewater treatment plant. Records will be
maintained at the landfill throughout the operating life and during the post-closure care period. In
addition to leachate generation quantities, the County maintains analytical data from leachate
sampling events.
9.3 Leachate Monitoring
The chemical composition of untreated leachate will be analyzed as required by the treatment
facility. The leachate will be collected into laboratory provided containers directly from a
sampling port on the piping connected to the storage tank. The leachate will be analyzed semi-
annually for the Detection Monitoring constituents (EPA Appendix I list from Subtitle D) required
by Rule.1633, and for pH, specific conductance, BOD, COD, phosphate, nitrate and sulfate. Test
results will be submitted to the Solid Waste Section as required.
9.4 Leachate Disposal
Leachate from Unit 2, Phase 1 flows by gravity to a sump located in the northwest corner of Unit
2. Leachate from the Unit 2, Phase 1 sump is pumped from the landfill area via side-slope riser
directly to the leachate storage tank. The leachate will be periodically removed from the tank by
pumping into a tanker truck for transport to the City of Oxford wastewater plant for treatment and
disposal. An agreement with the City of Oxford is in place for the discharge of wastewater from
the landfill to the plant (see Appendix 2). Although no pretreatment of the leachate is currently
required, the new tank is designed so that a pretreatment system can be retrofitted if necessary for
future treatment.
9.5 Contingency Plan for Extreme Conditions
The landfill staff hauls leachate from the tank to the wastewater treatment plant using three
dedicated tanker trucks by a private hauler. If required, additional hauling capacity will be
obtained from subcontract haulers or by the rental of additional tanker trucks. Truck drivers shall
remain with their vehicle during loading to provide continuous visual inspection to prevent
overfilling or accidental release. For any observed leak, action is taken to properly contain or
remove accumulations of leachate. If the leak is sufficiently large enough to cause accumulation
in a contained area, the leak will be promptly corrected or repaired. To prevent overflow at the
storage area, the leachate collection tank is accompanied with a high level alarm and the tank is
surrounded by a secondary storage tank to prevent spills due to tank failure. If for some reason the
receiving facility no longer accepts the leachate, it will be pre-treated to facilitate acceptance, or
hauled to another POTW or commercial pretreatment facility.
Operations Plan 19 Joyce Engineering
Oxford MSW Landfill Permit Renewal Rev. September 2014, Rev. November 2015
Granville County, North Carolina Revised August 2017, Revised January 2019
9.6 Handling Leaks and Stormwater in the Leachate Collection Tank Area
Being an above ground tank, any leaks in the primary containment system will be readily apparent
during routine operations and inspections. If a leak develops in either the primary containment
tank, or piping leading to or from the tank, any water (stormwater or otherwise) that has
accumulated in the secondary containment area will be treated as leachate and pumped back into
the primary containment area for disposal. For normal storm events in which rainwater
accumulates in the secondary containment area, the Operator will verify that there are no visible
leaks in the system and then may discharge the rainwater into the surface stormwater management
system.
9.7 Operations in the Leachate Loadout Area
Appropriate warning signs will be posted in the filling station that relate to safe operations around
the loading area. Smoking is not allowed on the landfill property. Site speed limits will be posted,
although not necessarily in the leachate loading area. The facility does have traffic signs and
markers to promote orderly traffic patterns and to maintain safe and efficient operating conditions.
The capacity of the loadout area spill containment collection basin is approximately 186 ft3 or
approximately 1,400 gallons. Small spills will be allowed to evaporate from the concrete basin,
and a dedicated pump for this area will load larger spills into the tanker truck or a vacuum truck
may be used. In the event that the system is inundated and leachate leaves the area, the County
will follow spill response procedures as outlined in the site NPDES permit.
10.0 CONTINGENCY PLAN
This section details the Contingency Plan for the Oxford Landfill facility. This plan has been
developed to protect human health and the environment from fires, explosions, or any unplanned

Report Requirements
A written report detailing the event will be placed in the landfill record and a copy will be sent to
the Department within fifteen days of the incident.
10.4 SEVERE WEATHER CONDITIONS
Ice Storms
An ice storm can make access to the landfill dangerous, prevent movement or placement of
periodic cover, and thus, may require closure of the landfill until the ice is removed or melted.
Heavy Rains
Exposed soil surfaces can create a muddy situation in some portions of the landfill during rainy
periods. The control of drainage and use of crushed stone on unpaved roads should provide all-
Operations Plan 23 Joyce Engineering
Oxford MSW Landfill Permit Renewal Rev. September 2014, Rev. November 2015
Granville County, North Carolina Revised August 2017, Revised January 2019
weather access for the site and promote drainage away from critical areas. In areas where the
aggregate surface is washed away or otherwise damaged, new aggregate should be used for repair.
Intense rains can affect newly constructed drainage structures such as swales, diversions, cover
soils, and vegetation. After such a rain event, inspection by landfill personnel will be initiated and
corrective measures taken to repair any damage found before the next rainfall.
Electrical Storms
The open area of a landfill is susceptible to the hazards of an electrical storm. If necessary,
landfilling activities will be temporarily suspended during such an event. To guarantee the safety
of all field personnel, refuge will be taken in the on-site buildings or in rubber-tired vehicles.
Windy Conditions
The proposed operational sequence minimizes the occurrence of unsheltered operations relative to
prevailing winds. If this is not adequate during a particularly windy period, work will be
temporarily shifted to a more sheltered area. When this is done, the previously exposed face will
be immediately covered with daily cover.
Violent Storms
In the event of hurricane, tornado, or severe winter storm warning issued by the National Weather
Service, landfill operations may be temporarily suspended until the warning is lifted. Daily cover
will be placed on exposed waste and buildings and equipment will be properly secured.

1.0 CLOSURE ACTIVITIES
Pursuant to the North Carolina Solid Waste Management Rules (15A NCAC 13B .1627), this
Closure and Post-Closure Plan is submitted as part of the permit application to construct Unit 2,
Phase 1 of the Oxford Landfill near Oxford, North Carolina. Currently the landfill operates a
C&D Unit on top of a closed MSW landfill. This plan describes proposed closure and post-
closure activities for the proposed Unit 2, Phase 1 MSW facility, site modifications, and site
characteristics. Please note that references are made herein to information and drawings found in
the Facility, Operation, and Engineering Plans in an effort to reduce redundancy in this report.
Grading plans, cap sections, and other aspects related to closure, including phased development,
stormwater management, and erosion and sediment control are discussed in the Facility,
Engineering, and Operations Plans, and are illustrated in the drawings. The Construction Quality
Assurance (CQA) Plan submitted with the Permit to Construct Application in June 2009 by
Joyce Engineering (JOYCE) and revised in January 2012 describes methods and procedures used
in monitoring construction of the closure cap, which can be found Volume 2 Section V of the
Permit to Construct Application. Detailed drawings, specifications, and other documents will be
prepared prior to closure for bidding and construction purposes.
The facility will be closed in accordance with the requirements of EPA's Subtitle D regulations
(40 CFR 258.60) and Rule .1627 of the North Carolina Solid Waste Management Rules (15A
NCAC 13 B). The waste disposal areas are proposed to be closed incrementally as described in
the following paragraphs.
1.1 Closure of Disposal Units
1.1.1 Cap Design
Proposed final grading contours for the entire facility are provided on Drawing No. FP-04 of the
Facility Plan. Final contours have been designed with post-settlement surface slopes of at least
five percent on top of the cell. Cross-sectional details of the proposed closure cap are provided
on Drawing No. EP-06. The following components are proposed as shown on the details:
a. Intermediate Cover and Leveling Course - Local soil will be placed over the daily
cover soil to provide at least 12 inches of intermediate cover and a uniform base
for construction of the cap.
b. Passive Gas Vents – Passive gas vents will be installed at a frequency of one per
acre. A typical passive gas vent is detailed on Drawing No. EP-15. Passive
venting of landfill gasses will protect the integrity of the cap by preventing
excessive pressure buildup beneath the cap.

Oxford MSW Landfill Permit Renewal June 2009, Revised January 2012
Granville County, North Carolina Revised August 2017, Revised January 2019
c. Gas Collection/Migration Layer – A geonet composite will be installed between
the intermediate cover and the overlying infiltration layer. The geonet composite
will provide a pathway for accumulated gas to move laterally to the gas vents.
d. Infiltration Layer: Clay component: - The infiltration layer is proposed to consist
of a geosynthetic clay liner. This layer will be constructed over the geonet
composite that will serve as the gas migration layer. Installation and testing
requirements for the cap are provided in the Specifications appendix of the
Engineering Plan and the CQA Plan.
e. Infiltration Layer: Geomembrane Component - The geomembrane component of
the infiltration layer will consist of a textured 40 mil flexible membrane cap
(FMC). The membrane will be in direct contact with the underlying layer. The
testing program and quality assurance requirements for the geomembrane are
described in the CQA Plan.
f. Geocomposite Drainage Layer - A drainage layer consisting of a geonet and
geotextile composite will be placed directly over the geomembrane to promote
drainage.
g. Protective Layer - A layer consisting of at least 18 inches of local soil will be
placed above the drainage layer to provide a protective cover for the underlying
cap components. Compaction of the layer will be limited to about 90 percent
(plus or minus three percent) of the Standard Proctor maximum dry density so
that the vegetation can develop a strong root system, and to avoid damage to the
underlying synthetic components.
h. Erosion Layer - A layer of topsoil material or organically amended local soil will
be placed above the protective layer. This soil layer will be at least 6 inches in
thickness. The topsoil material will be lightly compacted so that a good stand of
vegetation can be established. Soil tests will be conducted prior to seeding to
determine if soil additives are needed to establish vegetation.
i. Vegetation - After placement of the erosion layer, the area will be seeded.
Seeding will be accomplished in accordance with the "North Carolina Erosion and
Sediment Control Planning and Design Manual", and recommendations from
local agricultural specialists. Mulch and erosion matting will be used as needed to
control erosion and promote vegetative growth. The vegetative cover will be
inspected regularly. Areas found to be sparsely covered will be revegetated.
1.1.2 Area to Be Capped
The landfill is designed so that closure can occur in stages. Partial closure can occur when final
contours are reached, and the waste appears reasonably stabilized, in a given area. Once an area
of sufficient size to make construction cost-effective has reach final elevations, closure activities

will be carried out according to the schedule presented later in this section. With the construction
of Unit 2 Phase 1 it is anticipated to be partially closed and a section will be incorporated into
Unit 2 Phase 2. However if Unit 2 Phase 2 is not approved for construction the total area for Unit
2 Phase 1 (11 acres) will need to be capped. A cost estimate for closure for this area is provided
as Appendix VII-2.
1.1.3 Cap Settlement and Stability
Non-uniform settlement can be expected over the entire area. The primary mechanism of
settlement is waste consolidation due to decomposition of the landfilled material. According to
Daniel et al, long-term settlement is typically 5 to 15 percent over 20 to 30 years; however,
settlement of about 5 percent can be expected in the first few months following waste placement.
A significant amount of waste consolidation will likely have occurred by the time each portion of
the landfill is closed.
The stability of the proposed cap design under static and seismic conditions has been evaluated
and is included in the Engineering Plan. The standard regulatory cap design was found to be
stable at a slope of 3H:1V.
After the final cap is completed, monthly inspections of the final cover will be conducted to look
for areas of the cap that might have experienced displacement. Should these inspections indicate
problem areas (ponding, exposure of the geomembrane, deep cracks, etc.) repairs will be
initiated as soon as practical.
1.1.4 Drainage and Erosion
A combination of drainage ditches, diversion berms, vegetative cover, and sediment traps and
basins will control drainage and erosion. Construction and design of sediment and erosion
control features will be in accordance with applicable sections of the "North Carolina Erosion
and Sediment Control Planning and Design Manual." Drainage will be directed to perimeter
ditches that either exist now or will be constructed. These ditches will receive runoff from the
final cap, conveying the flow to sediment control features. For a detailed discussion regarding
stormwater management and erosion and sediment control, please refer to the Erosion and
Sediment Control Plan submitted under separate cover.
1.1.5 Freeze/Thaw Effects
Based on a published map of frost depths throughout the United States (US Army Corps of
Engineers EM 1110-1-1905, October 1992), the anticipated maximum depth of freeze/thaw
effects on the site is approximately 16 inches. Since the upper 18 inches of final cover soil is not
the low-permeability component of the cap, the effects of freeze/thaw cycles on the closure cap
should not be detrimental to its function.

1.2 Waste Volume
An estimate of the quantity of waste to be disposed in Unit 2, Phase 1 is provided in Table 2 of
the Facility Plan. The calculation is based on the airspace provided by proposed base and final
grades, and assumptions regarding the density of waste and the amount of cover soil in the fill.
Allowances for the airspace occupied by the bottom liner and cap were made. The estimate was
determined using the following steps:
1. Estimate the total airspace in cubic yards using AutoDesk Civil3D software. The total
airspace is considered to be the total volume between the bottom of the liner and the top
of the cap system.
2. Estimate the volume (cubic yards) occupied by the liner and cap.
3. Subtract the liner and cap volume from the total airspace volume to estimate the net
airspace available for waste disposal.
4. Assume a waste density of 1,100 pounds per cubic yard (0.55 tons per cubic yard);
multiply the waste volume by 0.55 to convert the waste volume to tons of waste to be
disposed.
Using the above procedure, the estimated total volume of waste that can be disposed in proposed
Unit 2, Phase 1 is approximately 660,000 cubic yards, or approximately 363,000 tons.
1.3 Closure Plan Schedule
As discussed in the Facility Plan, Unit 2 has a projected operating life of approximately 24 years.
Thus, closure of the entire landfill is not anticipated until 2045 assuming waste disposal in Phase
begins in 2021. However, the landfill is designed so that it can be closed incrementally as final
contours are reached in various areas. Prior to beginning final closure, Granville County will
notify the Division that a notice of intent to close the facility has been placed in the operating
record. An itemized list of closure milestones and a proposed schedule follow. Closure activities
are proposed to begin within 30 days of final receipt of waste. Construction of the closure cap is
to be completed within 180 days following the initiation of closure activities. The total length of
the proposed closure period is 210 days following the final receipt of waste.
The approximate closure milestones shown in Table 1 below are proposed for use in tracking the
progress of closure activities. A detailed schedule will be established prior to construction.

entrance. The site will be secured through the use of gates equipped with locks, fencing, and/or
natural barriers. The site will be baited for rodent and vector control before final closure is
initiated.
1.5 Notification
Once closure is complete, a survey plat will be prepared by a registered land surveyor showing
the locations and dimensions of the landfill disposal areas, the locations of groundwater
monitoring wells and gas probes, and the restrictions on future disturbance of the site. A notation
will be recorded on the property deed stating that the land has been used to dispose solid waste
and that its use is restricted under the Closure Plan as required by Rule .1627(c)(8). Copies of
the deed notations as recorded will be placed in the Operating Record and forwarded to the
Division.
1.6 Certification
Upon completion of closure, a licensed professional engineer acting on behalf of the owner will
submit a Certification of Closure to the Division. This Certification will state that the site was
closed in accordance with the Closure Plan and applicable solid waste regulations and laws as
required by Rule .1627(c)(7).
The owner must record a notation on the deed to the landfill facility property at the local county
Registrar of Deeds office, or some other instrument that is normally examined during title search,
and notify the division that the notation has been recorded and a copy has been placed in the
operating record. The notation shall in perpetuity notify any potential purchaser of the property
that the land has been used as a MSW facility and its use is restricted under the closure plan
approved by the Division.

PHONE NUMBER: (919) 603-1355
FAX: (919) 690-8610
2.2 Security
Access to the site will be controlled by the use of barriers and gates at roadway entrances. These
control devices will be maintained throughout the post-closure care period, and inspected as part
of the monthly inspection program. All barriers and gates will be clearly marked with signs
stating the name and nature of the facility and the person to contact in case of emergency or
breach of security.
2.3 Post-Closure Maintenance
Post-closure maintenance and monitoring will be conducted at the Oxford Landfill for a period
of 30 years after final closure. The Division may decrease the length of the post-closure period if
the owner or operator demonstrates that the reduced period is sufficient to protect human health
and the environment, and the Division approves this demonstration. The period might be
increased by the Division if the Division determines that the lengthened period is necessary to
protect human health and the environment. Access roads extending from the public road towards
the closed unit and monitoring points will be all-weather and conditions will be monitored.
Additional maintenance will be performed as needed to ensure access is maintained at all times.
Monitoring will include semi-annual sampling of groundwater and surface water, quarterly gas
monitoring, and monthly inspection of the final cover and monitoring and control systems.

days after the discovery, and within 24 hours if a danger or eminent threat to human health or the
environment is indicated. Minor cap maintenance may be deferred until there is a sufficient
amount of work to justify the mobilization of equipment and personnel. Unusual or extreme
maintenance needs due to calamities or vandalism might require the implementation of
emergency contract service procedures established by Granville County.
2.4 Inspection Plan
Routine inspections will be conducted throughout the post-closure care period. These
inspections will be carried out monthly unless problems are detected that indicate that more
frequent visits are warranted. Potential impacts to the public and environment will be considered
in determining the inspection frequency. The landfill cover will be inspected throughout the
post-closure care period. It is not expected that the landfill will experience significant
settlement. However, if any areas appear to have settled and standing water is observed, these
areas will be re-graded to promote positive drainage and will be reseeded. Edge-of-waste
markers that were installed during the operation of the landfill will be inspected for preservation.
Additional items to be included in the monthly inspection will be as follows:
x Access and security control
x Final cover settlement, subsidence, and displacement
x Integrity of edge-of-waste markers
x Leachate management and storage systems
x Stormwater management
x Erosion and sediment control
x Gas management
x Groundwater, surface water, and landfill gas monitoring systems
x Vector control
Inspection forms have been prepared for use during each inspection (see Appendix VII-3).
Completed copies of the inspection forms will be kept by the owner, and copies will be
forwarded to the Division for its records.
2.5 Monitoring Plan
2.5.1 Groundwater Monitoring
Groundwater monitoring will occur semi-annually throughout the post-closure care period. The
monitoring schedule will continue as established during the active life of the facility. The
applicable procedures outlined in Rules .1633 through .1637 will be followed through post-
closure as required by site findings. Refer to the Water Quality Monitoring Plan in Section X,
Volume 3 of the original Permit to Construct Application submitted by Joyce Engineering
(JOYCE) in 2009, revised in January 2012, for details regarding the monitoring program.

quality of the groundwater after the 30-year post-closure care period, a request will be made to
terminate the groundwater monitoring program. All groundwater-monitoring wells will be
maintained so that future monitoring can be resumed if desired. A blank groundwater
monitoring well maintenance record form is provided in Appendix VII-4.
2.5.2 Surface Water Monitoring
Surface water will be monitored according to the Water Quality Monitoring Plan provided in
Section X, Volume 3 of the original Permit to Construct Application submitted by Joyce
Engineering (JOYCE) in 2009, revised in January 2012.
2.5.3 Landfill Gas Monitoring
Landfill gas will be monitored quarterly at permanent gas probes and in all on-site structures. A
typical landfill gas monitoring probe is shown on Drawing No. EP-15. The monitoring schedule
will continue as established during the active life of the facility. Refer to the Operation Plan for
details regarding the landfill gas monitoring program. A blank methane monitoring test report
form is provided in Appendix VII-5.
2.5.4 Stormwater, Erosion, and Sedimentation Control Facilities
Stormwater management features proposed in the Erosion and Sediment Control Plan are
designed to function throughout the post-closure care period. Drainage ditches and sediment
control features will be inspected and maintained as needed to control surface water runoff and
erosion.
2.5.5 Leachate Management and Closure Plan
Leachate management will continue according to the approved practices at the facility during the
post-closure period as long as leachate continues to be generated. The leachate collection system
will be checked periodically and maintained to prevent clogging. Tanker trucks will be used as
needed to haul leachate to the wastewater treatment plant for disposal.
When leachate collection ceases, the following closure activities will be completed within 180
days: Leachate removal pipes will be securely plugged, and liquid and solid waste will be
removed from the storage facilities and associated piping. In accordance with Rule
.1680(f)(3)(B), the double-walled leachate containment tank will be securely fasten to prevent
unauthorized access. The tank will be stenciled with the date of removal. Contaminated subsoils,
structures, and equipment will also be removed. Material that is removed will be disposed in
accordance with applicable requirements.

2.6 Training
Personnel responsible for conducting monitoring activities, site inspections and maintenance will
be competent individuals trained in the skills needed for their job. Personnel will continue to
receive training as new programs become available.
Groundwater and surface water monitoring will be performed by a qualified firm, and laboratory
analysis will be conducted by a certified environmental laboratory.
2.7 Post-Closure Land Use
The primary land use for the site after closure of the landfill will be open dormant green space.
Limited passive recreational uses may be proposed at a later time. Also, at the end of the solar
project’s life, the solar project will be decommissioned. The solar project site will be returned to
pre-development use, which includes receive, process, and temporarily stockpile yard waste and
land clearing debris, and to conduct active composting activities, with the removal of the solar
array system.

1.0 INTRODUCTION
This Landfill Gas Monitoring Plan (LFGMP) will serve as a guidance document for collecting
and monitoring of landfill gas at the Granville County Oxford Landfill Permit No. 39-01.
Landfill gas will be monitored quarterly to ensure that methane concentrations do not exceed the
regulatory limit at the facility boundary or in facility structures. The LFGMP was prepared in
accordance with the North Carolina Department of Environment and Natural Resources (NC
DENR) Division of Waste Management Solid Waste Section (SWS) Landfill Gas Monitoring
Guidance document, to assure performance standards are met and to protect human health and
the environment.
1.1 Background
The Oxford Landfill is located at 6584 Landfill Road, Oxford, Granville County, North Carolina,
near the town of Kinton Fork. The facility is owned and operated by Granville County under
Permit Number 39-01, issued by the North Carolina Department of Environment and Natural
Resources (DENR) Solid Waste Section (SWS). The Oxford Landfill consists of two separate
waste disposal units. Unit 1(Permit Number 3901-CDLF-1997) is a former unlined municipal
solid waste (MSW) landfill originally permitted for disposal of domestic, institutional, industrial,
agricultural, and demolition wastes, with an active C&D landfill on top. The Unit 2 landfill
(Permit Number 3901-MSWLF-2012) is a Subtitle-D MSW landfill. Granville County received
the Unit 2 Permit to Operate from DENR on February 19, 2013. The county began placing
waste in Unit 2 on May 1, 2013.
1.2 Site Geology and Hydrogeology
The Oxford Landfill is located in the Carolina Slate Belt of the Piedmont Physiographic Province
of North Carolina. The geologic province is characterized by rolling topography with a thick
mantle of saprolite overlying late-Proterozoic and Paleozoic igneous and metamorphic bedrock.
The Carolina Slate Belt is comprised of 550 to 650 million year old, metamorphosed
sedimentary and volcanic rocks, intruded by granitic rocks.
The Oxford Landfill is underlain by the Flat River Complex, a shallow intrusive complex of
granitic composition, which comprises a large portion of the northern Carolina Slate Belt (Butler,
1991). The landfill is approximately 18 miles east of the Virgilina Synclinorium, approximately
10 miles west of the Nutbush Creek Fault Zone, and approximately 4 miles northwest of the
Durham Basin (Butler, 1991).
Previous investigations discovered limited exposures in the borrow area of a competent, massive,
gray to greenish gray meta-volcanic rock that is moderately fractured with prominent fractures
with near vertical dips and striking approximately N25o to 30oW (Woodward-Clyde, 1994).
Boring logs indicate that the depth to bedrock at Oxford Landfill ranges from 5 to 30 feet below
ground surface. The overlying saprolite consists of brownish sandy to clayey silt (Woodward-
Clyde, 1994).

Granville County Oxford Landfills, Permit No. 39-01 August 2014 (Rev. January 2018)

Groundwater in the Piedmont can occur in substantial volumes where soils and regolith are thick,
but groundwater is typically found in minimal volumes in bedrock, primarily restricted to
fractures. The water table under the area landfill was encountered in the unconfined aquifer that
is mostly in the transition zone that consists of saprolite and highly fractured bedrock. This
unconfined aquifer is pervasive across the site and generally mimics the surface topography.
The saturated portion of the uppermost aquifer beneath the landfill is vertically continuous to
bedrock, and no confining layers have been encountered during permitting. There is a high
degree of connectivity between the saprolite and underlying fractured bedrock such that they
behave as a single continuous aquifer. Depth to water ranged from 3 to 22 feet below grade.
1.3 Regulatory Limits
North Carolina Solid Waste Management Rules 15A NCAC 13B require quarterly monitoring of
methane gas at MSW landfills and quarterly monitoring of methane and other explosive landfill
gasses at C&D landfills to ensure that landfill gas does not exceed the lower explosive limit
(LEL) at the facility boundary or 25 percent of the LEL in facility structures. The LEL for
methane equals 5% by volume at standard temperature and pressure. This LFGMP prescribes a
routine methane monitoring program to ensure standards are met and actions to be taken if
methane concentrations exceed specified limits.
2.0 LANDFILL GAS MONITORING
Gas monitoring at the Granville County, Oxford Landfills will be performed throughout the
active and post-closure care period for the facility. At a minimum, quarterly monitoring will be
conducted at all subsurface gas detection probes and facility structures.
2.1 Landfill Gas Monitoring Network
The locations of the network of landfill gas monitoring probes are shown on Drawing 1. The
landfill gas monitoring network consists of 10 compliance boundary gas probes (GP-1A, GP -2,
GP-3A, GP-4, GP-5, GP-6, GP-7, GP-10, GP-11, and GP-12), 4 voluntary gas probes (GP-1,
GP-3, GP-8, and GP-9), and 2 structures (scale house and shop).
As part of the groundwater corrective action, a landfill gas intercept trench was installed with 6
vents along the northeast corner of the Unit 1 landfill. The landfill gas intercept trench vents will
be voluntarily monitored in conjunction with the quarterly compliance monitoring. The
following table summarizing the landfill gas monitoring network. In addition, the locations of all
of the monitoring probes, structures and trench vents are shown on Drawing 1.

2.2 Structure Sampling
There are currently two structures (scale house and shop) on the facility property that will be
monitored for landfill gas. The scale house and shop are shown on Drawing 1.
2.3 Landfill Gas Monitoring Frequency
The landfill gas compliance probes included in this LFGMP will be monitored at least quarterly
in accordance to current regulations.
3.0 LANDFILL GAS SAMPLING PROCEDURES
Landfill gas samples will be collected in accordance with Solid Waste Section’s (SWS) Landfill
Gas Monitoring Guidance document. Details of detection equipment and sampling procedures
are outlined below.
3.1 Detection Equipment
A portable combustible gas monitor, measuring the concentration of combustible gases in units
of percent of LEL, shall be used to conduct gas monitoring. The LEL is the lowest percent by
volume of a mixture of combustible gas in air that will propagate a flame at 25 degrees Celsius
and atmospheric pressure. The LEL for methane is 5%.
Landfill Gas Monitoring Plan Joyce Engineering
Granville County Oxford Landfills, Permit No. 39-01 August 2014 (Rev. January 2018)
4
The gas monitor shall be calibrated to methane using the manufacturer's calibration kit and
procedure before the monitoring activities begin. The calibration gas to be used depends on the
expected levels of methane in landfill gas monitoring probes. If low levels of methane are
expected, 15% CO2/15% CH4 calibration gas should be used. If high levels of methane are
expected, 35% CO2/ 50% CH4 calibration gas should be used. Verification that the equipment
was calibrated in accordance with the manufacture’s specifications is required. Calibration
information must be recorded on the Landfill Gas Monitoring Data Form.
3.2 Landfill Gas Sampling Procedure
The portable combustible gas monitor will be turned on and allowed to warm up prior to gas
sampling. The static pressure should show a reading of zero before taking the initial sample. The
sample tube shall be purged for at least one minute prior to connecting the sample tube to the
detection well, and then the initial concentration will be recorded. Gas monitoring will continue
until the reading has stabilized. A stable reading is considered to be +/- 0.5% by volume on the
instrument’s scale. Once the reading has stabilized for 5 seconds, the reading will be recorded
and the tubing will be disconnected from the valve. These steps will be repeated for each landfill
gas monitoring well.
Gas monitoring in on-site structures will attempt to identify the "worst case" concentrations. The
monitoring locations will be in corners along floors and ceilings, at cracks in the floor, and at
other areas likely to accumulate gas. Gas monitoring will also be conducted in any confined
space requiring the entry of personnel for maintenance or inspection. The monitoring will take
place prior to entry by personnel in accordance with OSHA regulations.
4.0 RECORD KEEPING AND REPORTING
The landfill gas data will be recorded in accordance to the SWS’s Landfill Gas Monitoring
Guidance document included as Appendix I. The records will be maintained in the landfill
operating record. An example landfill gas monitoring data form is included as Appendix II.
4.1 Notifications
In the event that an exceedance of the regulatory levels is observed, the DENR shall be notified
within 24 hours of the observation, and the monitoring results and a description of the steps
taken to protect human health, shall be placed in the facility’s operating record within seven
calendar days of the observation.
4.2 Sampling Reports
The landfill gas monitoring report will be prepared in accordance with the NC DENR Division
of Waste Management Solid Waste Section Landfill Gas Monitoring Guidance document. The
report will describe the method of sampling, the date, time, location, sampling personnel,
atmospheric temperature, reported barometric pressure, equipment calibration information,
exceptions noted during sampling, and general weather conditions at the time of sampling, in
addition to the concentration of combustible gases.

4.3 Permanent Record Keeping
A copy of the landfill gas monitoring results and any remediation plans will be maintained in the
landfill operating record. The reports will be maintained at an alternative location near the
facility approved by the Division of Waste Management (Division).
5.0 CONTINGENCY PLAN
If methane gas levels that exceed the regulatory limits are detected, the results shall be reported
to Granville County immediately. The County shall immediately take all necessary steps to
insure protection of human health. Granville County will notify the SWS in via phone or email
within 24 hours and in writing (fax and email are acceptable) within 7 calendar days.
If methane levels exceed the LEL in existing gas probes, the need for additional gas probes will
be evaluated, as well as the need for monitoring within any nearby structures in the direction of
the gas migration. If the exceedance is in a gas well not located at or near a property boundary,
additional investigation including use of bar-hole probes or temporary gas probes may be
implemented to determine whether or not the exceedance extends to the property boundary. If
necessary, additional permanent gas probes may be installed between the exceeding well(s) and
the property boundary to demonstrate that the site is in compliance.
If the compliance level (25% LEL) is exceeded in an on-site structure, options will be evaluated
to reduce the current methane levels and to prevent further migration of methane into the
structure. At a minimum, the following actions will be taken if the methane concentration
exceeds 25% of the LEL in any structure:
Put out all smoking materials and turn off all ignition sources;
Evacuate all personnel;
Vent the structure;
Do not allow personnel to reenter the building except to perform gas monitoring until the
results of additional monitoring indicate that methane concentrations are sustained or
stabilized below 25% of the LEL;
Begin continuous monitoring within the structure; and
Undertake an assessment to determine the origin and pathways of the gas migration
Within seven calendar days of detection, the monitoring results will be placed in the operating
record and Granville County will indicate actions taken and actions proposed to resolve the
problem. Within 60 days of detection, Granville County will develop and implement a landfill
gas remediation plan for the combustible gas releases and notify the Division that the plan has
been implemented. The plan will describe the nature and extent of the problem and the proposed
remedy.

1.0 INTRODUCTION
On behalf of Granville County, Joyce Engineering (JOYCE) has prepared this Water Quality
Monitoring Plan (WQMP) for the Oxford Landfill Units 1 & 2 (facility) in accordance with 15A
NCAC 13B.1632-.1637 of the North Carolina Solid Waste Management Rules (NCSWMR). The
Unit 1 of the facility is currently in Assessment Monitoring (§.1634) and Corrective Action. Unit
2 of the facility is currently in Detection Monitoring.
1.1 Site Background
The Oxford Landfill is located at 6584 Landfill Road, Oxford, Granville County, North Carolina,
near the town of Kinton Fork (Figure 1). The facility is owned and operated by Granville County
under Permit Numbers 3901-CDLF-1997 (Unit 1) and 3901-MSWlLF-2012 (Unit 2), issued by
the North Carolina Department of Environmental Quality (NCDEQ) [formerly the Department of
Environment and Natural Resources (DENR)] Solid Waste Section (SWS). The Oxford Landfill
consists of two separate waste disposal units: Unit 1 is a former unlined municipal solid waste
(MSW) landfill with a C&D landfill on top; and Unit 2 is a Subtitle-D MSW landfill. The
permitted facility consists of approximately 283 acres, of which approximately 29 acres constitutes
the Unit 1 waste unit and 37.3 acres constitutes Unit 2.
Unit 1 was originally permitted for disposal of domestic, institutional, industrial, agricultural, and
demolition wastes in 1981. The Unit 1 MSW landfill was closed in 1997. Between 1997 and
2017, the facility disposed of construction and demolition (C&D) waste on top of the closed Unit
1 MSW landfill in accordance with the facility’s Transition Plan dated 1994. The facility stopped
disposing of C&D waste in this unit in the summer of 2017 and closure of the Unit 1 C&D landfill
is expected to begin in spring 2018. Unit 1 is currently in Assessment Monitoring and Corrective
Action.
Unit 2 is a Subtitle-D MSW landfill permitted for disposal of domestic, institutional, industrial,
agricultural, and demolition wastes. Granville County received the Unit 2 Permit to Operate from
the NCDEQ on February 19, 2013. The County began placing waste in Phase 1 of Unit 2 on May
1, 2013. Unit 2 is currently in Detection Monitoring.
1.2 Site Geology and Hydrology
1.2.1 Site Geology
The Oxford Landfill is located in the Carolina Slate Belt of the Piedmont Physiographic Province
of North Carolina. The geologic province is characterized by a rolling topography with a thick
mantle of saprolite overlying Late Proterozoic and Paleozoic igneous and metamorphic bedrock.
Water Quality Monitoring Plan Joyce Engineering
Oxford Landfill, Permit No. 39-01 January 2018
2
The Carolina Slate Belt is comprised of 550 to 650 million year old, metamorphosed sedimentary
and volcanic rocks, intruded by granitic rocks.
The Oxford Landfill is underlain by the Flat River Complex, which is a shallow intrusive complex
of granitic composition, which comprises a large portion of the northern Carolina Slate Belt
(Butler, 1991). The landfill is approximately 18 miles east of the Virgilina Synclinorium,
approximately 10 miles west of the Nutbush Creek Fault Zone, and approximately 4 miles
northwest of the Durham Basin (Butler, 1991).
Previous investigations discovered limited exposures in the borrow area of a competent, massive,
gray to greenish gray meta-volcanic rock that is moderately fractured with prominent fractures
with near vertical dips and striking approximately N25o to 30oW (Woodward-Clyde, 1994).
Boring logs indicate that the depth to bedrock at Oxford Landfill ranges from 5 to 30 feet below
ground surface. The overlying saprolite consists of brownish sandy to clayey silt (Woodward-
Clyde, 1994).
1.2.2 Site Hydrogeology
Groundwater in the Piedmont can occur in substantial volumes where soils and regolith are thick,
but groundwater is typically found in minimal volumes in bedrock, primarily restricted to fractures.
The water table under the area of investigation was encountered in the unconfined aquifer that is
mostly in the transition zone that consists of saprolite and highly fractured bedrock. This
unconfined aquifer is pervasive across the site and generally mimics the surface topography. The
saturated portion of the uppermost aquifer beneath the site is vertically continuous to bedrock, and
no confining layers have been encountered during previous site investigations. There is a high
degree of connectivity between the saprolite and underlying fractured bedrock such that they
behave as a single continuous aquifer. Depth to water ranged from 5 to 10 feet below grade in
wells MW-4R, MW-6R, NES-2S, and NES-2D; and 10 to 25 feet below grade in MW-1A, MW-2,
MW-3R, MW-5R, MW-7, NES-1S, and NES-1D. In general, the water table is near the
saprolite/bedrock interface. Well construction details for the facility’s monitoring wells are
summarized in Table 1, and historical groundwater elevations are presented in Table 2.
Groundwater in the saprolite feeds the fractures in the bedrock and is expected to discharge into
creeks located northeast of the landfill. Groundwater flow at deeper levels within the fractured
bedrock is controlled by fractures. A groundwater potentiometric surface map, based on static
water level data obtained on August 23, 2017, is presented as Drawing 1. The groundwater map
depicts groundwater flow to the north.
1.3 Aquifer Characteristics & Groundwater Flow Regime
Depth to groundwater is measured in all compliance monitoring wells at the site prior to each
sampling event. The groundwater elevations calculated relative to the surveyed measuring point
(top of casing) for each monitoring well are summarized in Table 2. The groundwater elevation
contours shown in Drawing 1 are based on data from the August 2017 sampling event.
Water Quality Monitoring Plan Joyce Engineering
Oxford Landfill, Permit No. 39-01 January 2018

Groundwater flow beneath the Landfill is primarily to the north. Horizontal groundwater gradients
were estimated from the August 2017 groundwater levels and are summarized in Table 3.
Horizontal gradients across the site ranged from 0.0185 to 0.0220. These values are consistent
with previous estimates.
Linear groundwater flow velocities for wells screened in saprolite were computed using the
following modified Darcy equation: V = Ki/n , where V = average linear velocity (feet/year),
K = hydraulic conductivity (feet/day), i = horizontal hydraulic gradient, and n = effective porosity.
The arithmetic mean of hydraulic conductivities from slug-tests conducted in 1995, 1999 and 2004
(K = 2.54 ft/day) were used in these calculations, along with an estimated effective porosity of
0.45 based on 85% of the average of laboratory-determined porosities for site soil (0.53). The
average estimated linear groundwater flow velocity under the facility was calculated at 42.6 ft/year
(Table 3). The linear velocity equation makes the simplifying assumptions of a homogeneous and
isotropic aquifer.
1.4 Monitoring History and Regulatory Status
1.4.1 Monitoring History

the SWS with an updated list of COCs, removing 1,1-dichloroethane and beta-BHC from
the COC list.
July 8, 2016: Well NES-1D was abandoned.
1.4.2 Regulatory Status
The Oxford Unit 1 Landfill has remained in Assessment Monitoring since 1995 due to detections
of organic constituents. There were NC2L Standard exceedances of benzene in MW-4R in 2003,
which have not been detected since, and there have been persistent NC2L exceedances of vinyl
chloride in MW-5R from 2003 to present, but with generally decreasing trends. The County
received a letter from the SWS dated August 20, 2003, that requested the County to proceed with
assessment activities at Oxford Unit 1 Landfill. A meeting between JOYCE and the SWS was
held on February 11, 2004, to discuss the SWS’s requirements for a Nature and Extent Study
(NES) and an Assessment of Corrective Measures (ACM). In May 2005, Granville County
submitted a NES (JOYCE, 2005a), and an ACM (JOYCE, 2005b) and a Quantitative Risk
Assessment (QRA) (JOYCE, 2005c) to the NCDEQ in accordance with 15A NCAC 13B.1634.
Granville County held a public meeting for the ACM on August 21, 2006. A CAP was submitted
in June 2008, with revisions in October 2008 and March 2009 (JOYCE, 2009). The CAP proposed
Monitored Natural Attenuation (MNA) as the primary remedy, supplemented with Control of
Decomposition Gasses as a secondary remedy. The CAP was approved in a letter from NCDEQ-
SWS dated April 23, 2009. The gas interception trench proposed in the Control of Decomposition
Gasses was installed July 2009. The last sampling event for the Baseline MNA was completed in
December 2010.
An Alternate Source Demonstration for Iron and Manganese was submitted to the SWS October
26, 2010, after the requirements for additional constituent monitoring for C&D facilities showed
elevated concentrations of iron and manganese across multiple site wells in June 2010. The ASD
showed that the concentrations of iron and manganese were a result of natural occurrence in site
soil and not a release from the landfill. The ASD for Iron and Manganese was approved as
described by the SWS on June 9, 2011.
The first CAER was submitted to the SWS on November 29, 2010, and in a letter dated January
27, 2011, the SWS reviewed and approved the CAER. The SWS denied a request to remove some
of the MNA parameters made on behalf of the county, but did approve a reduced alternate

monitoring frequency as follows; carbon dioxide, ferrous iron, volatile fatty acids, total organic
carbon (TOC), sulfide, and dissolved ethane and ethene for every third year on a semiannual basis.
NCDEQ-SWS also approved removing benzene and cis-1,2-dichloroethylene from the COC list
and adding 1,1-dichloroethane. As a result, the current COC list includes vinyl chloride and 1,1-
dichloroethane. The ASD for chromium, thallium, and total dissolved solids in MW-1A was also
approved. The Oxford Unit 1 landfill continues in Assessment Monitoring, with additional C&D
indicator parameters and selected MNA parameters and COC monitored at designated wells at
frequencies presented in the January 27, 2011 SWS review of the CAER and ASD and summarized
in the next section.
1.4.3 Monitoring Well History
The original background well, MW-1, was replaced by MW-1A as the background well in 1999
and MW-1 was abandoned in 2001 after being damaged by a vehicle. MW-1 and MW-1A were
located near the scale house south of Unit 1, off of the Drawing 1 map area. A Request for
Background Well Replacement was submitted to the SWS October 25, 2010 because the
background monitoring well, MW-1A, was dry or affected by low water levels and excessive
sediment as well as possible bore seal damage. The request proposed piezometer P-2 to be
upgraded and re-named MW-7 to become the facility background monitoring well. NCDEQ-
SWS approved the request on December 23, 2010, and MW-7 became the background monitoring
well for the first semiannual sampling event of 2011. MW-1A is still monitored for static water
level.
Monitoring wells MW-3R, MW-4R, MW-5R, and MW-6R replaced MW-3, MW-4, MW-5, and
MW-6, respectively, in August 1999, due to the close proximity to waste of the original wells.
Monitoring wells NES-1S, NES-1D, NES-2S, and NES-2D were installed as part of the NES in
May 2004 and were designated as corrective action performance/sentinel wells in the facility’s
CAP approved in April 2009.
MW-9, MW-10, MW-11 were originally installed in 2008 as piezometers PZ-9, PZ-10, PZ-13,
and PZ-21, respectively, for hydrogeological investigations; however they were converted to
permanent monitoring wells in 2012 to monitor Unit 2, Phase 1. MW-8 was installed in 2012 to
monitor the Unit 2 leachate tank area. MW-12 was originally installed in 2008 as piezometer
PZ-21 and it was converted to a monitoring well in 2012 to be used as a background well for Phase
1 of Unit 2; however, it was later decided the MW-7 would be the background well for both Units,
so MW-12 has never been a part of the compliance network.
In May 2014, Granville County requested several changes to the designations and monitoring
requirements for some of the facility’s monitoring wells. The requested changes included:
MW-2R, MW-3R, MW-4R, and MW-6R will revert to detection monitoring; NES-1S and NES-1D
will be removed from the corrective action monitoring network; and MNA parameters will no
longer be required for MW-3R and MW-4R. These changes were approved by the NCDEQ in
June 2014. NES-1D was abandoned in July 2016 after being damaged.

2.1.2 Unit 2 Monitoring Program
Six groundwater monitoring wells comprise the compliance monitoring network at the Oxford
Unit 2 Landfill. The compliance network includes monitoring wells MW-7 (the current facility
background well), MW-8 (which monitors the leachate tank area), MW-9, MW-10, MW-11, and
NES-2S. The locations of these wells are shown on Drawing 1. All monitoring wells are sampled
for the North Carolina Appendix I list of constituents during both semiannual sampling events.
2.2 Surface Water Monitoring Program
There are two surface water sampling points associated with Unit 1, SW-1 and SW-2; and there
are two surface water sampling points associated with Unit 2, SW-3 and SW-4. Sampling point
SW-1 is located in a sedimentation basin near the southeast corner of Unit 1, upgradient of the
waste. Sampling point SW-2 is located northeast of Unit 1, along a tributary of Little Grassy
Creek, down-gradient of the waste. SW-3 is located upstream of Unit 2, on the perennial creek
that runs along the east side of Unit 2. SW-4 is located on the same perennial creek downstream
of the Unit 2, but before the confluence of the perennial creek and the drainage channel from the
west side of Unit 2, between Units 1 and 2. The surface water samples are analyzed for the
Appendix I list of constituents during both semiannual events.
3.0 SAMPLING PROTOCOLS
3.1 Groundwater Sampling Methodology
Groundwater samples will be collected in accordance with Solid Waste Management Rules 15A
NCAC 13B .1630 through .1633 and guidance provided in the Draft North Carolina Water Quality
Monitoring Guidance Document for Solid Waste Facilities; Solid Waste Section, Division of Solid
Waste Management; Department of Environment, Health and Natural Resources (March 1995).
Details of well purging, sample withdrawal, and decontamination methods, as well as chain-of-
custody procedures are outlined below.
Static water elevations and the total well depth will be measured to the nearest 0.01 of a foot in
each well prior to the sampling of each well. An electronic water level meter will be used for the
measurements, or other methods if they provide similar accuracy and precision. The distance from
the top of the well casing to the water surface and to the bottom of the well will be measured using
the tape attached to the probe. Reference elevations of the proposed wells have been obtained
from a North Carolina registered land surveyor.
A low-yield well (one that is incapable of yielding three well volumes within a reasonable time)
will be purged so that water is removed from the bottom of the screened interval. Low-yield wells

will be evacuated to dryness. Within 24 hours of purging, the first sample will be field tested for
pH, temperature, and specific conductance. Samples will then be collected and containerized in
the order of the parameters' volatilization sensitivity (i.e., volatile organics then total metals).
A high-yield well (one that is capable of yielding more than three well volumes during purging)
will be purged so that water is drawn down from the uppermost part of the water column to ensure
that fresh water from the formation will move upward in the screen. At no time will a well be
evacuated to dryness if the recharge rate causes the formation water to vigorously cascade down
the sides of the screen, which could cause an accelerated loss of volatiles.
A minimum of three well volumes will be evacuated from high-yield wells prior to sampling. A
well volume is defined as the water contained within the well casing and pore spaces of the
surrounding filter pack. The well volume will be calculated using the following formulas:
Vc = (dc2/4) x3.14 x hw x (7.48 gallons/cubic foot)
Vc (gallons) = 0.163 x hw (for a 2-inch well)
where:
Vc = volume in the well casing in gallons
dc = casing diameter in feet (dc = 0.167 for a 2-inch well)
hw = height of the water column in feet (i.e., well depth minus depth to water)
Each well will be evacuated (purged) and sampled with a disposable bailer or a sampling pump.
The bailer or pump will be lowered gently into the well to minimize the possibility of causing
degassing of the water. If sampled with a pump, flow rates will be regulated to minimize turbidity
and degassing of the water.
All equipment used for sampling will be handled in such a manner to ensure that the equipment
remains decontaminated prior to use. In between wells and following completion of the field
sampling, water level meters, sampling pumps, or any other reusable sampling equipment will be
properly decontaminated. Clean disposable gloves will be worn by sampling personnel and
changed between wells.
The upgradient/background well will be sampled first, followed by the downgradient wells. The
order of sampling of the downgradient wells will be evaluated each sampling event to provide a
sequence going from less contaminated to more contaminated, if applicable, based on the previous
sampling event.
Field measurements of temperature, pH, and specific conductance will be made before sample
collection. The direct reading equipment used at each well will be calibrated according to the
manufacturer's specifications prior to each sampling event and the calibrations shall be
documented in the field logs. Groundwater samples will be collected and containerized in the
order of the volatilization sensitivity (i.e., VOCs first, followed by the metals).

Pre-preserved sample containers will be supplied by the laboratory. The VOC vials will be filled
in such a manner that no headspace remains after filling. Immediately upon collection, all samples
will be placed in coolers on ice where they will be stored prior to/and during transit to the
laboratory.
In between wells and following completion of the field sampling, the electronic depth meter will
be decontaminated using the following procedure.
1) Phosphate-free soap and distilled water wash;
2) Distilled water rinse;
3) Air dry.
Samples collected will be properly containerized, packed into pre-cooled coolers, and either hand-
delivered or shipped via overnight courier to the laboratory for analysis. The chain-of-custody
program will allow for tracing of possession and handling of samples from the time of field
collection through laboratory analysis. The chain-of-custody program will include sample labels
and seals, field logs, commercial carrier’s parcel bills, chains-of-custody, and laboratory logs.
Example field logs and an example chain of custody are included in Appendix C.
Labels sufficiently durable to remain legible when wet will contain the following information:
Job and sample identification;
Monitoring well number or other location;
Date and time of collection;
Name of collector;
Parameter to be analyzed; and
Preservative, if applicable.
The shipping container will be sealed to ensure that the samples have not been disturbed during
transport to the laboratory. If the sample cannot be analyzed because of damage or disturbance,
whenever possible, the damaged sample will be replaced during the same compliance period.
The field logs will , at a minimum, document the following information:
Identification of the well;
Well depth;
Static water level depth;
Presence of immiscible layers, odors or other indications of potential contamination;
Purge volume (given in gallons or number of bailers);
Time well was purged;
Date and time of sample collection;
Field analysis data and methods;
Name of collector(s);
Climatic conditions (temperature, precipitation).
Water Quality Monitoring Plan Joyce Engineering
Oxford Landfill, Permit No. 39-01 January 2018

The chain-of-custody record is required to establish the documentation necessary to trace sample
possession from time of collection to time of receipt at destination. A chain-of-custody record will
accompany each individual shipment. The record will contain the following information:
Sample destination and transporter;
Sample identification numbers;
Signature of collector;
Date and time of collection;
Sample type(s);
Identification of well(s);
Number of sample containers in shipping container;
Parameters requested for analysis;
Signature of person(s) involved in the chain of possession;
Inclusive dates of possession; and
Internal temperature of shipping container upon opening (noted by the laboratory).
A copy of the completed chain-of-custody will accompany the shipment and will be returned to
the shipper with the analytical results. The chain of custody record will also be used as the analysis
request sheet.
A field/equipment blank will be collected and analyzed during each sampling event to verify that
the sample collection and handling processes have not affected the integrity of the field samples.
The field/equipment blank will be prepared in the field from lab pure water (Type II reagent grade
water) supplied by the laboratory. One field/equipment blank will be prepared for each sampling
event. The field/equipment blank will be generated by exposing the lab pure water to the sampling
environment and sampling equipment/media in the same manner as actual field samples being
collected. The lab will provide appropriate sample containers for generation of the field/equipment
blank(s). The field/equipment blank will be subjected to the same analyses as the groundwater
samples. As with all other samples, the time(s) of the field/equipment blank collection will be
recorded so that the sampling sequence is documented. The field/equipment blank monitors for
contamination from the sampling equipment/media, or from cross-contamination that might occur
between samples and sample containers as they are opened and exposed to the sampling
environment.
Whenever groundwater samples are being collected for volatiles analysis, a trip blank will be
generated by the laboratory prior to shipment of sampling containers and coolers to the field. The
same lab pure water as above shall be used. The trip blank shall be transported with the empty
sampling containers to the field, but will not be opened at any time prior to analysis at the
laboratory. The trip blank will accompany the groundwater samples in the cooler(s) with the
samples collected for VOC analyses back to the laboratory and will be analyzed by the same
volatile methods as the associated field samples. The trip blank monitors for potential cross-
contamination that might occur between samples or that may be a result of the shipping
environment.

Detectable levels of contaminants found in the field/equipment blanks or trip blanks will not be
used to correct the groundwater data, but will be noted accordingly. Contaminants present in trip
blanks or field/equipment blanks at concentrations within an order of magnitude of those observed
in the corresponding groundwater samples may be cause for resampling.
3.2 Surface Water Sampling Methodology
Surface water samples will be collected from flowing water at the designated sample locations in
conjunction with the semiannual groundwater sampling events. Surface water can be sampled
either by: 1) collecting the sample using a properly-decontaminated graduated dipper and filling
laboratory-prepared sample containers from the dipper; or 2) by dipping laboratory-prepared
sampled containers directly into the stream flow. If using the direct sampling method, great care
should be taken to not overflow containers containing preservatives to prevent loss of preservative.
Use of an unpreserved laboratory container to collect the sample and then carefully dispense it into
the preserved container is acceptable. For unpreserved containers, it is preferable to completely
submerge the closed container, removing the lid underwater, and then replacing the lid when the
container is full before removing it from the water; however, this method is only acceptable if
there is sufficient depth of flowing water. No matter what method is used to collect samples, great
care should be taken to not disturb creek bed sediment during sampling, and to obtain samples
from the least turbid location available. Downstream samples should be collected first and
upstream samples second. Samplers should wear clean, dedicated sampling gloves at all times
while collecting or handling samples. Field parameters, including temperature, pH, and turbidity,
shall be monitored at each sample location using the same sample collection technique used to
collect the laboratory samples, as appropriate. Sampling techniques and protocols describe above
for groundwater, including sample labeling, field log entry, and chain-of-custody procedures, shall
also be followed for surface water samples.
3.3 Sample Analytical Requirements
3.3.1 Analytical Requirements
Analysis of groundwater and surface water samples from the facility will be conducted by a
laboratory certified by the NCDEQ for the required analytical methods (15A NCAC 2H.0800).
Analyses will be performed in accordance with U.S. EPA SW-846 methods. Both groundwater
and surface water samples will be analyzed for the constituents listed in 40 CFR Part 258,
Appendix I. In addition, field analyses for temperature, pH, and specific conductance will be
performed for each sample. Samples from wells in Assessment Monitoring will also be sampled
for all 40 CFR Part 258 Appendix II constituents during the first semiannual sampling event each
year and for previously detected Appendix II parameters during the second semiannual sampling
event.
Appendix A includes a table of all Appendix I and Appendix II constituents with their respective
analytical methods, CAS numbers, NCDEQ Solid Waste Section Limits (SWSL), 15A NCAC 2L
(NC2L) groundwater standards, and Solid Waste Section groundwater protection standards
(GWPS). Appendix B includes a summary of 15A NCAC 2B (NC-2B) Surface Water Standards.

3.3.2 Reporting and Record Keeping
The laboratory analytical results will be submitted to the Solid Waste Section at least semiannually.
The following measurements, analytical data, calculations, and other relevant groundwater
monitoring records will be kept throughout the active life of the facility and the post-closure care
period:
Records of all groundwater quality data;
Associated sample collection field logs and measurements, such as static water level
measured in compliance wells at the time of sample collection; and
Notices and reports of GPS exceedances, reporting or data error, missing data, etc.
3.4 Groundwater Comparison to GPS
Constituents detected in the samples collected from either the compliance network or the sentinel
well shall be compared to the appropriate Groundwater Protection Standard (GPS) for that
constituent in accordance with NCSWMR §.1634.g. The comparison will be performed using a
value-to-value procedure. If a suspect GPS exceedance is noted during the value-to-value
comparison, a confirmation sample may be collected. The results from a confirmation sample will
be compared to the GPS in a value-to-value comparison, or the value may be statistically compared
to background.
In most cases, the GPS will be equal to the Groundwater Standard established for a given
constituent in 15A NCAC 2L.0202 (NC2L Standards). For constituents without listed NC2L
Standards, the groundwater protection standards (GWPS) established by the NCDEQ Solid Waste
Section may be used. In accordance with 15A NCAC 2L.202, if the quantitation limit (SWSL) is
higher that the listed standard, the standard is the quantitation limit; therefore, estimated
concertations below the SWSL are not considered GPS exceedances even of the estimated value
is greater than the listed GPS. In the event that a site-specific statistical background value can be
established for a given constituent which is higher that the NC2L standard, GWPS, or other
appropriate listed standard, the background may be used as the GPS with NCDEQ approval.
3.5 Statistical Analyses
With the April 2011 revision to the NCSWMR, routine statistical comparison to background for
all detected constituents is no longer required; however, statistical analyses may be used to
establish an alternate GPS for constituents with the approval of the NCDEQ if desired by the
facility. The following guidelines will be used to determine statistical background values.
The background data are to be evaluated through the use of Parametric Prediction Limits,
Parametric Tolerance Intervals, Non-Parametric Prediction Limits, or Poisson Prediction Limits
as appropriate. Tests for normality, outliers, Aitchison’s adjustment, tolerance intervals, or
prediction limits are to be included as appropriate based on the background data.
Water Quality Monitoring Plan Joyce Engineering
Oxford Landfill, Permit No. 39-01 January 2018
13
The statistical test by which downgradient data are compared to facility background data is based
upon the nature of the data and the number of data values that are less than the laboratory limit of
detection. All statistical tests are evaluated at the 0.05 level of significance, 95% confidence level,
and are conducted as one-tailed tests. These methods and the criteria for their use are discussed
below.
3.5.1 Treatment of Censored Data
Generally, background data are censored as follows. When less than or equal to 15% of the
background data values are less than the applicable reporting limit (SWSL), any data reported less
than the SWSL will be treated as one-half the SWSL.
3.5.2 Assumption of Normality
Prior to conducting statistical tests that are based on the assumption of normally distributed data,
normality of the background data is evaluated using the Shapiro-Wilk statistic (W). Normality is
assessed at the 95% confidence level. In the event that the raw data fail to follow a normal
distribution, the data are transformed using a base-10 logarithm. The transformed data are then
tested for normality using the Shapiro-Wilk statistic. In the event that the log-transformed data
also fail to follow a normal distribution, a non-parametric approach is applied.
3.5.3 Parametric Upper Tolerance Limit
In some cases the background data consist of a minimum of eight independent data values and less
than or equal to 15% of the background data values are less than the RL for a given analyte. The
downgradient values are then compared to the parametric upper tolerance limit in accordance with
the procedure summarized in the USEPA guidance documents, Statistical Analysis of
Groundwater Monitoring Data at RCRA Facilities, Unified Guidance (US-EPA, 2009).
3.5.4 Aitchison’s Adjusted Parametric Upper Prediction Limit
In those cases where the background data consist of a minimum of eight independent data values
and more than 15%, but less than or equal to 50%, of the background data values are less than the
RL for a given analyte, the mean and standard deviation are adjusted. This is done in accordance
with the procedure described by Aitchison and summarized in the USEPA guidance document
(US-EPA, 2009). After the adjustments are made, the downgradient values are compared to the
Aitchison’s adjusted parametric upper prediction limit in accordance with the procedures
summarized in the USEPA guidance document (US-EPA, 2009).
3.5.5 Non-parametric Upper Tolerance Limit
In those cases where more than 50%, but less than or equal to 90%, of the background data values
are less than the RL for a given analyte or the background data fail to follow a normal or log-
normal distribution, downgradient values are compared to the non-parametric upper tolerance
Water Quality Monitoring Plan Joyce Engineering
Oxford Landfill, Permit No. 39-01 January 2018
14
limit. This procedure is done in accordance with the procedures summarized in the USEPA
guidance document (US-EPA, 2009).
3.5.6 Poisson Upper Prediction Limit
In those cases where more than 90% of the background data values are less than the RL for a given
analyte, the downgradient values are compared to the Poisson upper prediction limit. These
comparisons are made in accordance with the procedure summarized in the USEPA guidance
document (US-EPA, 2009).
3.6 Surface Water Comparison to Standards
Surface water at the facility is currently monitored semiannually in conjunction with the
groundwater sampling events. Samples are collected from four surface water monitoring points,
SW-1, SW-2, SW-3, and SW-4. Surface water samples will be collected and analyzed for the
NCSWMR Appendix I list of constituents during both semiannual monitoring events. The results
will be compared to 15A NCAC 2B (NC2B) Surface Water Standards in a value-to-value
comparison. Some of the NC2B standards for metals are hardness-based, so the standards can be
adjusted based on the hardness of the surface water samples. If no hardness data are available, the
standards based on a presumed hardness of 25 mg/l will be used.
4.0 ABILITY TO EFFECTIVELY MONITOR RELEASES
Based on the hydrogeologic data available for the Oxford Landfill, no geological or hydrological
conditions have been identified which will interfere with effective monitoring of groundwater
beneath the facility. The existing monitoring network is considered adequate to monitor this
facility. This Water Quality Monitoring Plan will be effective in providing detection of any release
of landfill constituents to the uppermost aquifer beneath the facility as well as monitoring of
existing releases, so as to be protective of public health and the environment.

See 15A NCAC 02B .0211 for more information. The standards in this table are developed per section 15A NCAC 02B of the North Carolina Administrative Code. To determine the appropriate standard, use the most stringent of all applicable columns as described below. For Class C waters, use the most stringent of Freshwater and Human Health. For Class SC waters, use the most stringent of Saltwater and Human Health.For Water Supply waters, use the most stringent of Freshwater, Water Supply, and Human Health.For Swamp Waters, use the most stringent of Freshwater or Swamp for freshwaters or Saltwater or Swamp for tidal waters.(1) Trout Waters are protected for natural trout propagation and survival of stocked trout. See 15A NCAC 02B .0101 and .0301(3) Human Health standards are based on the consumption of fish only unless dermal contact studies are available. See 15A NCAC 02B .0208.(4) High Quality Waters are a subset of waters with quality higher than the standards and are described in 15A NCAC 02B .0101 and .0224.(5) Swamp Waters have low velocities and other natural characteristics which are different from adjacent streams. See 15A NCAC 02B .0101.(6) Carcinogens are listed in 15A NCAC 02B .0208.For High Quality Waters, use the most stringent of Freshwater, Water Supply, Trout, and High Quality or the most stringent of Saltwater and High Quality.(2) Water Supply standards are applicable to all Water Supply Classifications and are based on consumption of fish and water. See 15A NCAC 02B .0208, .0212, .0214, .0215, .0216, and .0218.Footnotes, Codes and Additional Information with Reference to Classifications & StandardsValues in red font are 15A NCAC 02B standards(h) = hardness‐dependent dissolved metal standard. All hardness‐dependent dissolved metal standards in this table assume ≤ 25 mg/L in‐stream hardness. See page 16 for hardness‐dependent dissolved metal guidelines and equations.
