1.0 INTRODUCTION
The Westside C&D Landfill facility is located near Wilson, North Carolina and is owned and
operated by Wilson County (County) under NC Solid Waste Permit No. 9809-CDLF. The landfill
facility includes an active construction and demolition debris (C&D) landfill, scales and scale
house facilities, administrative offices, a maintenance building, a white goods, scrap metal, and
tire handling area, a citizen's convenience center, and a recycling building. The facility also has
one (1) closed MSW landfill unit (NC Solid Waste Permit No. 9801-MSWLF-1990) which is
maintained by the County.
Wilson County currently operates Area 1 which is expected to be depleted of permitted volume
in mid to late 2021. Once Area 1 has reached capacity, the County will need to expand laterally
into the proposed Area 2 landfill unit. The purpose of this Facility and Engineering Plan is to
present the updated plans for the development of Area 2, and to specifically discuss the detailed
design of Area 2. It is the intent of Wilson County begin construction of Area 2 in 2021.
1.1 Site Description
Area 2 is located in the central portion of the facility, west of Area 1, across Buck
Branch. The topographic relief of the site is approximately 34 feet, ranging from
elevation 114 feet at the northern end of the proposed Area 2 to elevation 90 feet at the
southern end. Existing conditions are shown on Drawing S1 of the Permit to Construct
Drawings (Attachment M of this Permit to Construct Application). Access to Area 2 will
use the existing landfill entrance off Highway 42.
The proposed Area 2 C&D landfill unit will occupy approximately 17.2 acres. At the
projected gate rates described in Section 2.0 (Facility Report), Area 2 has been designed
for approximately 42.1 years of disposal volume. Additionally, Area 2 has been designed
to meet current DWM setback and horizontal buffer requirements: 200 feet from
property lines, 500 feet from residences or active water wells, and 200 feet form surface
water features (i.e., stream, river, creek, etc.).
2.0 FACILITY REPORT
This section presents an updated plan for the development of the Area 2 C&D landfill unit of the
Westside C&D Landfill facility. This report has been prepared in accordance with the
requirements of Rule .0537 and .0539 of the North Carolina Solid Waste Management Rules.

2.1.2 Types of Waste
The Westside C&D Landfill accepts construction and demolition debris (C&D)
generated within the approved service area (Section 2.1.41. A further discussion
on acceptable waste, prohibited waste, and waste handling can be found in the
Operations Manual (Attachment I of this Permit to Construct Application).
2.1.3 Disposal Rates and Estimated Variances
Based on the 2010-2019 Solid Waste Management Annual Reports information
provided by the County, the landfill accepted approximately 17,400 tons per year,
on average. As documented during the local government approval process
(Attachment D of this Permit to Construct Application), the County has set a
maximum disposal rate of 50,000 tons per year for the landfill. For purposes of
facility life expectancy calculations, a disposal rate of 17,500 tons per year is
assumed.
2.1.4 Service Area
The landfill facility currently serves Wilson County.
2.1.5 Procedures for Waste SeOre0ation
Procedures for waste segregation at the proposed landfill will be similar to
existing operations in Area 1 including requirements for waste screening and

DocuSign Envelope ID: E4CD1420-42E0-46D6-A48E-BC6299FBE42B
contingency plans for managing unacceptable wastes. Refer to the Operations
Manual (Attachment I of this Permit to Construct Application) for more
information.
2.1.6 Equipment Requirements
The County will maintain on -site equipment required to perform the necessary
landfill activities. Periodic maintenance of all landfilling equipment, and minor
and major repair work will be performed at designated maintenance zones.
Refer to the Operations Manual (Attachment I of this Permit to Construct
Application) for more information.
3.0 LANDFILL CAPACITY
3.1 Total Operating Capacity and Life Expectancy
Drawing S2 and Drawing S3 (Attachment M of this Permit to Construct Application),
show proposed subgrade and final cover grades for the development of Area 2,
respectively. The final cover side slopes will be at a 3H to 1V slope, then transition at
flatter slopes (5 to 8%) to the peak elevations.
The estimated gross volume, net (waste) capacity, life expectancies, and areas of Area 2
phases are shown in Table 1. The net (waste) capacity and corresponding life expectancy
of each phase accounts for periodic cover and/or final cover. Life expectancies were
calculated based on a disposal rate of 17,500 tons per year.
3.2 Airsoace Utilization Factor and Percentage of Periodic Cover Soil
The capacities shown in Table 1 were based on a 10 percent periodic cover ratio and an
airspace utilization factor (AUF) of 1,000 pounds per cubic yard (pcy) which are typical for
C&D landfills.
Note that changes in landfill operations (i.e. changes in compaction equipment/methods)
may affect the values assumed above and, thus, alter the life of the landfill.
4.0 AVAILABLE SOIL RESOURCES AND REQUIRED SOIL QUANTITIES
4.1 Earthwork Quantities
The soils required to construct and operate the proposed Areas 2 will be removed from
on -site borrow sources or imported from off -site. The soils removed during excavation
of landfill units may be used for structural fill, periodic cover, final cover, and general
fill.

July 2020 (Revised October 2021) Page 3

DocuSign Envelope ID: E4CD1420-42E0-46D6-A48E-BC6299FBE42B
4.2 Periodic Cover
Assuming the previously mentioned periodic cover ratios, the required in -place volume
for use as periodic cover during operations of each landfill unit is shown in Table 2.
4.3 Final Cover
On the basis of the 2-foot-thick vegetative soil layer required for the (alternate) landfill
final cover system, the in -place volume required for each landfill unit is shown in Table
3.
4.4 Soil Summary
The above on -site and off -site soil quantities are summarized in Table 4. Note that,
based on the proposed base grades, long-term there is a soil deficit of on -site soil within
the proposed Area 2 footprint. However, there is anticipated to be sufficient soil in
existing on -site borrow areas shown on Drawing S1 (Attachment M of this Permit to
Construct Application). Off -site soil will be acquired, as necessary, for landfilling
operations.
5.0 FACILITY DESIGN CRITERIA
Area 2 will be constructed in accordance with Section .0540 of the North Carolina Administrative
Code, Title 15A, Chapter 13, Subchapter 13B including the following requirements:
5.1 Horizontal Separation Requirements
The horizontal separation requirement between the disposal boundary (edge of waste)
and the property lines is a minimum of 200 feet; the minimum buffer between private
residences and wells and the disposal boundary is 500 feet; and the minimum buffer
between any surface water (stream, river, creek) and the disposal boundary is 200 feet.
The proposed design satisfies all buffer requirements.
5.2 Vertical Separation Requirements
The post -settlement bottom elevation of the liner system will meet the minimum
requirement of four (4) feet above the seasonal high groundwater table and bedrock.
6.0 CONTAIN M ENT AND ENVIRONMENTAL CONTROL SYSTEMS
The following systems and elements are the basic containment and environmental controls for
the Area 2 C&D landfill unit. Technical specifications and construction quality assurance
requirements can be found in Attachments G and H of this Permit to Construct Application,
respectively.

July 2020 (Revised October 2021) Page 4

DocuSign Envelope ID: E4CD1420-42E0-46D6-A48E-BC6299FBE42B
6.1 Landfill Subgrade and Perimeter Berms
The subgrade elevations will be achieved by excavation or placement of compacted
structural fill (embankment). During excavation, a determination of unsuitable soils (i.e.
soils which are too soft, wet, or organic) will be made. Where unsuitable soils are found,
the soils will be undercut and backfilled with structural fill. The landfill subgrade will
consist of two (2) feet of in -situ or modified soils consisting of the following: SC, SM, ML,
CL, MH, or CH soils.
In addition to providing the landfill subgrade in fill areas, structural fill will be used for
berm and roadway construction. Structural fill will consist of on -site soils removed
during excavation of the landfill units or imported borrow soils, except that no CH, OL, or
OH soils will be allowed.
6.2 Final Cover System
The final cover system will consist of the following components (top -down):
Regulatory Final Cover System (.0543(c)(1))
• An 18-inch-thick vegetative soil layer;
• An 18-inch-thick soil liner with a hydraulic conductivity (k) of no more
than 1.0 x 10-5 cm/sec ("compacted soil barrier"); and,
• A 12-inch-thick intermediate cover layer.
M'
Alternate Final Cover System (.0543(c)(3))
Top Slopes [5 to 8%
• a 24-inch-thick vegetative soil layer;
• a drainage geocomposite (with drainage breaks);
• a 40-mil textured LLDPE geomembrane; and,
• a 12-inch-thick intermediate cover layer.
Side Slopes (3H:lV)
• a 24-inch-thick vegetative soil layer.
The final cover system will be placed on prepared intermediate cover at a maximum
slope of 3H:1V. Surface water control devices and passive landfill gas (LFG) vents will
also be incorporated into the final cover system. The final cover surface will be
vegetated upon completion of the final cover installation according to the project seeding
specifications.

DocuSign Envelope ID: E4CD1420-42E0-46D6-A48E-BC6299FBE42B
A final cover infiltration analysis was performed to demonstrate that the proposed final
cover system allows less infiltration than the regulatory final cover system (see
Appendix A). Note that this permit application assumes the installation of the proposed
alternative final cover system.
An analysis of the final cover drainage layer (drainage geocomposite) is provided in
Appendix A. This analysis focused on determining the required transmissivity to
maintain the peak head within the drainage geocomposite. An analysis is also provided
in Appendix A which shows that the upper geotextile of the drainage geocomposite will
perform acceptably as a filter when covered with typical site soils.
6.3 Erosion and Sedimentation Control
Erosion and sedimentation control devices/measures will be designed and maintained to
manage the run-off generated by the 25-year 24-hour storm event and conform to the
requirements of the North Carolina Sedimentation Pollution Control Law (15A NCAC 4).
A detailed discussion of site erosion and sedimentation control can be found in the
Erosion and Sedimentation Control Plan (Attachment F of this Permit to Construct
Application).
6.4 Landfill Gas Control
The landfill gas (LFG) control system will consist of vents placed within the waste to
capture LFG and passively vent the gas. Vents will be placed in conjunction with the final
cover system.
6.5 Access and Roadways
The Westside C&D Landfill is accessed from NC Highway 42. A scale and a scale house
are located near this entrance. Drawing S1 (Attachment M of this Permit to Construct
Application) shows this infrastructure.
All-weather access to active areas as well as areas under periodic cover will be
provided. Access ramps into the landfill units will be provided where necessary.
7.0 SLOPE STABILITYAND SETTLEMENT
An evaluation of the veneer stability of the final cover system utilizing geosynthetics (top slopes)
as well as the slope stability of the overall waste mass of Area 2 is addressed in Appendix A.
Additionally, an evaluation of foundation settlement is addressed in Appendix A. These analyses
indicate that the proposed landfill configuration will be stable and will satisfy applicable
regulatory criteria.

SUBJECT Final Cover Infiltration Analysis JOB # WILSON-20-1 CHECKED BY WMB
OBJECTIVE: To determine the expected average annual infiltration into the landfill through the proposed final cover
system. In that the proposed final cover system is an alternate system to the regul atory final cover, the
infiltration through the proposed system is compared to the infiltration through the regulatory system.
Use the EPA HELP Model in the analysis.

OBJECTIVE: To evaluate the required transmissivityfor the drainage geocomposite placed in the final cover system.
REFERENCE: Richardson, GN., Groud, J-P., and Zhao, A. (2000), Design of Lateral Drainage Systems for Landfills,
Tenax Corp., Baltimore.
ANALYSIS:
Step1
Determine the required transmissivity (9fegd) of the drainage geocomposite based on the fol lowing equation:
_ RFdoq Li _ RFdoq Lcos,8 _ RFdoq L
Bid sin,6 sin,6 tan/3 (Richardson et. al. Eq. 4-6 Mod.)
where: 0""
= required transmissivitv (m3/m/sec)
RF,
= drainage geocomposite reduction factor (See Note 1)
q n
fluid input rate (or impingement rate) (m/s) (See Note 2)
L
= flow length (or drain spacing) (horizontally projected) (m)
6
= slope angle of final cover (degrees)
Notes:
1. Based on the recommendations of Richardson, Glroud, & Zhao, use RFd,, = 6. This accounts for an overall
factor of safety of 2, plus a combined reduction factor of 3 for long-term intrusion, creep, and clogging
concerns. A lower reduction factor may be used where veneer stability is not a significant concern.
2. Typically the impingement into the drainage geocomposite is determined by the lessor of:
a. Permeability of the overlying vegetative soil layer (k ,) or
b. Design rainfall.
Per Richardson, Giroud, & Zhao, use q n =k .9 except in arid/semi-arid areas.
Step 2:
Determine the required transmissivity test parameters:
- Normal Stress (cover thickness x unit weight of cover soil) and
- Hydraulic Gradient (approximately equal to slope of cover system for most slopes).
Step 3:
Calculate the required total flow capactiy (Q) of the drain basin on the following equation:
— q" A
where: C = flow capacity (cfs)
q I impingement (ft/s)
A = total area served by the drain (= L x DL) (ft)
DL = length of drain between outlet locations (ft).
Step 4:
After finding Qfor each drain, the designer shal I select the appropriate type and size of drain.

OBJECTIVE: To determine the maximum geotextile apparent opening size (AOS) to provide proper retention to protect
drainage media from piping and clogging from adjacent soil. Additionally, to determine the minimum
required geotextile permittivityto provide proper drainage from the adjacent soil. Geotextile filtration
properties must be selected based on the up -gradient soil gradation and plasticity and site specific
hydraulic conditions.

ASSUMPTIONS: The design criteria given assume that the soil is "set' in intimate contact with the geotextile.
BACKGROUND: From Richardson et. al.:
For the purposes of filtration design, soils can be characterized as stable or unstable. Stable soils perform
an internal filtration process that limits migration of fines within the soil. Typically, these soil types
include well -graded soils. Unstable soils are those which cannot perform self -filtration (i.e. they have the
potential to pipe internally). They may include gap -graded, broad -graded, and other highly erodible soils.
In gap -graded soils, there exists a coarse and fine fraction, but very little medium fraction. If there is an
insufficient quantity of soil particles in the medium fraction, fine soil particles pipe through the coarse
fraction. In broad -graded soils, the gradation is distributed over a very wide range of particle sizes such
that fine soil tends to pipe through coarser particles.
ANALYSIS: 1. Define Application and Function of Geotextile:
Define the application and function of the geotextile (i.e. where the geotextile is to be used and
whether retention or permeability is the keyfunction of the material) and also the confining
stress (i.e. high - leachate collection system; low - final cover system) and flow conditions (i.e.
steady-state- landfill drains; dynamic- shoreline protection).
2. Evaluate Soils Information
For representative soils, evaluate grain size and plasticity information. From the grain size
curves determine the coefficients of uniformity and curvature as follows:
= d6o C = d30
2
Cu
dio (dio X d60)
where: C = coefficient of uniformity (quantifies the distribution of particle sizes)
C, = coefficient of curvature (identifies internal soil stability)
ax = the diameter at which x percent of the soil is finer

For C <. 4, the soil is uniformly -graded; for 4 <C < 20, the soil is well -graded; and for C > 20,
the soil is broad -graded. Uniformly -graded and broad -graded soils require careful analysis.
Gap -graded soils which have a coarse and fine fraction, but limited medium fraction are of
particular concern and should be avoided. Gap -graded soils are readily identified by the
appearance of the grain size curve. For 1 . Cc s 3, the soil should be internally stable (Bhatia
and Huang state that soils having Cc <. 7 are internally stable.).
Additionally, in general, particles do not move within soils having a plasticity index (PI) greater
than 15% so there is no clogging potential (Richardson et. al.).
3. Selection of Soil Retention Requirements (Maximum AOSy.
To determine the maximum AOS, use the method given in Koerner/Mirafi (after Luettich) and
the method given in Bhatia and Huang. For the AOS determined by either method, the following
shows the relationship between opening size and the corresponding U.S. sieve number (with
typical non -woven geotextile information as shown).

For steady-state conditions, use the chart below.
- Bhatia and Huang Method:
Bhatia and Huang developed the following retention criteria:
For n , 60% C95 < d85(2.71 - 0.36Cc) Cc 6 7
For n < 60% C95 < d85(0.65 - 0.05Cc) Cc > 7
where: C 95 = apparent opening size
n = geotextile porosity (%) (for non -woven geotextiles this value is
typically 70 to 90%)
4. Determine Geotextile Permittivity Requirements:

5. Other Considerations
Other things to consider in the design of a filter geotextile include anti -clogging requirements
and survivability/durabil ity requirements. For anti -clogging, it is generally best to use the
largest AIDS that satisfies the retention criteria. For non -woven geotextiles used in landfill
applications, an AOSof 0.21 mm (No. 70 sieve) is typical lythe largest AIDS that is available. For
survivability/durability concerns, generally an adequately UVstabilized geotextile made from
polypropylene or polyester with an AASHTO M288 Strength Class of 2 is suitable for use in
subsurface drainage applications.

COMPUTED BY SWH
SUBJECT Final Cover Veneer Stability Evaluation JOB # WILSON-20-1 CHECKED BY WMB
OBJECTIVE: To determine the interface shear strength requirements for the final cover system veneer to satisfy the
required factor(s) of safety against sliding.
REFERENCE: Matasovic, N. (1991), "Selection of Method for Seismic Slope Stability Analysis," Proc. 2nd International
Conference on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics, St. Louis, Vol.
2, pp.1057-1062.
REQUIREMENTS: FSmi,(Static) = 1.5
FSmi (Seismic) = 1.0 (If Appl icable)
ANALYSIS:
1. Treat the final cover as an infinite slope and use the following equation
c
+tan
1-7, '-k,(tanflXtan8)
��
FS - ResistingForce - y,z, COS
71z11 ( Matasovic, 1991)
DrivingForce
ks + tan#
where: FS
= factor of safety against shallow veneer failure
ks
= seismic coefficient (= 0 for static conditions) (= peak ground acceleration
for seismic conditions)
y
= unit weight of final cover material(s) (pcf)
y W
= unit weight of water (62.4 pcf) (pcf)
c
= cohesion/adhesion along assumed failure surface (psf)
b
= interface friction angle along assumed failure surface (degrees)
2,
= depth of final cover (depth to failure surface) (ft)
a W
= depth to seepage surface (assumed parallel to slope) (ft)
6
= slope angle of final cover (degrees)
u =
Yw(zc — dw)
*Note: Based on an allowable
LFG pressure of 6 inch-w.c. (= 31.2 psf), the use of a depth to seepage of
1.5 feet or less (for evaluation of interfaces above the geomembrane) will satisfythe evaluation for LFG
pressure against the bottom of the geomembrane as well.
2. Determine minimum interface shear strength as follows:
z = 6tan 8+ c
where: r = interface shear strength (Ibs)
6 = normal load (psf)
S = interface friction angle (min. value from analysis or greater)
c = cohesion/adhesion (min. value from analysis or greater)

PROJECT Wilson CountyC&DLF SHEET 1 OF 1 DATE 10/13/2021
COMPUTED BY SWH
SUBJECT Area 2 Slope Stability Eval. JOB# WILSON-20-1 CHECKED BY WMB
OBJECTIVE: To perform a slope stability evaluation for the Area 2 C&DLF unit. Note that although the landfill is not in a
seismic impact zone (amax = 0.049), both static and seismic conditions were evaluated. For the evaluation
of seismic conditions, the pseudo -static seismic coefficient used was taken as half of the ground surface
acceleration value to account for the average acceleration predicted within the waste mass (EPA/600/R-
95/051). Based on EPA guidance for MSW landfills (EPA/600/R-95/051), landfills are required to have
minimum factors of safety of 1.5 and 1.0 for static and seismic conditions, respectively.
REFERENCE: Richardson, G.N., Kavazanjian, E., and N. Matasovic (1995), RCRA Subtitle D (258) Seismic Design Guidance
for Municipal Solid Waste Landfill Facilities, EPA/600/R-95/051, U.S. Environmental Protection Agency,
Washington, D.C.
ANALYSIS: This slope stability evaluation was performed using the computer program STABLSM, a computer
program developed by Purdue University.
The slope stability evaluation was performed on the cross section shown on the attached figure which is
believed to represent the critical cross section. The shear strength envelopes assumed for this evaluation
are as follows:
Subgrade/Berms: cohesion = 50 psf and phi = 20 degrees (See Note 1)
Waste: cohesion = 500 psf and phi = 25 degrees (See Note 2)
1. The shear strength envelope assumed for the subgrade/berms is believed to be conservative based on
soils encountered during site investigations and for structural fill.
2. The shear strength envelope assumed for waste is believed to be conservative for C&D wastes.
RESULTS: Based on the results of the evaluation (see below and attached), the minimum factors of safety satisfy EPA
guidelines.

Wilson County West Side COD Landfill
Facility Plan Information
1.0 INTRODUCTION
Wilson County, North Carolina (County) currently owns and operates the Westside C&D Landfill
facility at 2400 Hwy 42 East in Wilson. The facility is permitted for the disposal of construction
and demolition debris (C&D) under NC Solid Waste Permit 9809-CDLF. The County also
conducts several other solid waste management activities at the facility.
Based on current projections, Area 1, Phase 3 is expected to remain in operation until late 2020.
Once Area 1 has reached capacity, the County will need to expand laterally into the proposed
Area 2 landfill unit. The information contained herein is a brief description of the County's plans
to continue to operate and expand the C&D landfill.
2.0 FACILITY SERVICES AND WASTE STREAM
2.1 Facility Services
Currently, the following solid waste services are provided at the Westside C&D
Landfill facility:

• Citizen Convenience Center Area;
• Tire Collection Area;
• Wood Processing and Yard Trash Composting Area;
■ White Goods and Scrap Metal Staging Area;
