1.0 INTRODUCTION
The purpose of this report is to present the Facility Plan for the proposed Nash County
Construction & Demolition Landfill (C&DLF) and Horizontal Expansion in accordance with
Rule 15A NCAC 13B .0537.
Nash County satisfied the Local Government Approval requirements described in Rule
15A NCAC 13B .0536 Paragraph (c)(11) in late 2011. NCDENR issued concurrence that
the Local Government Approval process was satisfied on March 2, 2012.
Nash County owns and operates a 375 acre Solid Waste Management Facility (the
Facility) located approximately 1-mile west of the intersection of Taylor Store Road and
SR 1411 (Dukes Road) on the southern side and adjacent of SR 1411. The Facility is
comprised of two distinct facilities including includes the Closed MSWLF Landfill Facility
(permit 6401) and the C&DLF Facility (permit 6403) as shown on Sheet 1 of the Facility
Plan Drawings. The Closed MSW Landfill Facility Boundary (permit 6401) is 188.34
acres. The C&DLF Facility Boundary (permit 6403) is 186.76 acres.
The Solid Waste Management Facility provides numerous functions including, but not
limited to:
1) Construction and Demolition Landfill (C&DLF)
2) Closed Municipal Solid Waste Landfill (MSWLF)
3) Yard Waste Collection
4) White Goods Collection
5) Waste Tire Collection
6) Citizen Convenience Center
2.0 WASTE STREAM
Rule 15A NCAC 13B .0537(e)(1) requires a description of the proposed waste stream to
be managed by the facility.
2.1 TYPES OF WASTE SPECIFIED FOR DISPOSAL
The C&DLF Facility will accept the following types of wastes for Disposal:
A. Construction and Demolition (C&D) Waste: "C&D solid waste" means solid
waste generated solely from the construction, remodeling, repair, or demolition
operations on pavement and buildings or structures.
FACILITY PLAN
NASH COUNTY C&D LANDFILL
AND HORIZONTAL EXPANSION
Page 2 of 6
B. Inert Debris: “Inert Debris” is defined as solid waste which consists solely of
material that is virtually inert, such as brick, concrete, rock, and clean soil. For
the Nash County C&DLF, this term also includes wood pallets.
C. Asphalt: In accordance with G.S. 130-294(m).
D. Non Friable Asbestos: In accordance with 40 CFR 61.
E. Land Clearing Debris: As defined in G.S. 130A-290, specifically solid waste
which is generated solely from land-clearing activities, such as stumps, trees,
etc.
C&D waste does not include municipal and industrial wastes that may be generated
by the on-going operations at buildings or structures.
2.2 AVERAGE YEARLY DISPOSAL RATE
The Facility received approximately 5,000 tons in fiscal year 2014, which represents
a reduction from recent annual tonnages reported. During the Local Government
Approval process, approximately 10,000 tons of C&D were reported disposed in 2010,
or approximately 27 tons per day. The FY14 tonnage is considered an isolated
reduction in annual incoming tonnage. It is projected that the waste disposed will
increase about 2.0% annually over the life of the facility.
2.3 AREA SERVED BY THE FACILITY
The Nash County C&D Facility will serve the unincorporated and incorporated areas
of Nash County which includes all or portions of municipalities of Bailey, Castalia,
Dortches, Middlesex, Momeyer, Nashville, Red Oak, Rocky Mount, Sharpsburg,
Spring Hope, and Whitakers.
2.4 PROCEDURE FOR SEGREGATED MANAGEMENT AT DIFFERENT ON-SITE
FACILITIES
2.4.1 YARD WASTE
Nash County collects yard waste in the areas indicated on Sheet 1 of the
Engineering Drawings. Yard waste is stockpiled until there is a sufficient amount
to hire a Contractor to grind the material. The ground material is used for various
purposes around the County.
The existing Yard Waste Stockpile Area will be relocated in the future to
accommodate the C&D landfill expansion. The relocated Yard Waste Stockpile
Area is indicated on Sheet 2 of the Engineering Drawings.
FACILITY PLAN
NASH COUNTY C&D LANDFILL
AND HORIZONTAL EXPANSION
Page 3 of 6
2.4.2 WHITE GOODS
Nash County collects White Goods in the area noted on Sheet 1 of the Engineering
Drawings. Units requiring refrigerant removal (refrigerators, freezers, and air
conditioning units) are segregated in the “refrigerant removal” section of the White
Goods area. These units will be unloaded and handled in a manner to prevent
damage to the appliance that may cause refrigerant leakage as described in the
County’s White Goods Management Plan. After removal of refrigerant, the White
Goods unit will be placed into the white goods pile. The County contracts with a
private White Goods recycling vendor to collect the White Goods for transport and
recycling.
2.4.3 TIRES
Nash County collects waste tires in trailers in the area noted on Sheet 1 of the
Facility Drawings. The County contracts with a private waste tire recycling vendor
for transport and recycling and/or disposal.
2.5 EQUIPMENT REQUIREMETNS FOR OPERATION OF THE C&DLF UNIT
The equipment is county-owned and includes the following, or comparable:
1 – CAT 826C Compactor
1 – KOBELCO Model SIL 250 LC Track Excavator
1 – 613 CAT Scraper
1 – 623 CAT Scraper
Other equipment may be purchased or rented on an as-needed basis.
3.0 LANDFILL CAPACITY
Rule 15A NCAC 13B .0537(e)(2) requires an analysis of landfill capacity and soil
resources.
3.1 EXISTING PERMITTED 11.3-ACRE C&DLF
Nash County currently operates an 11.3-acre C&DLF Facility (Phase 1 - 3 C&DLF) as
shown on Sheet 1 of the Engineering Drawings, in accordance with permit No. 64-03
issued on April 20, 2005. The site was originally permitted in 2000 and the entire
permitted base grade footprint has been constructed and has received waste. All
remaining waste disposal capacity is accomplished by vertically expanding the current
footprint.
The 11.3-acre Nash County C&DLF had approximately 138,000 cubic yards of
useable airspace (airspace below the final cover elevations) remaining as of June 18,
FACILITY PLAN
NASH COUNTY C&D LANDFILL
AND HORIZONTAL EXPANSION
Page 4 of 6
2014. This capacity was calculated by using Terramodel CADD software to compute
the volume between an aerial survey of the 11.3-acre Nash County C&DLF completed
on June 18, 2014 and the proposed top of waste elevations.
The 11.3-acre Nash County C&DLF has an Airspace Utilization Factor (AUF) of 745
lbs/CY (pounds of waste per cubic yard of airspace utilized) between January 1, 2000
and June 18, 2014. The AUF was computed by dividing the pounds of waste disposed
from scalehouse records by the airspace utilized by this waste as calculated by using
Terramodel CADD software to compute the volume between the base grade
elevations of the 11.3-acre Nash County C&DLF and an aerial survey of Facility
complete on June 18, 2014.
Assuming the 11.3-acre Nash County C&DLF will continue to operate at a 745 lbs/CY
AUF, the remaining 138,000 cubic yards of useable airspace will provide 51,395 tons
of waste disposal capacity. Assuming the County receives 10,000 tons of C&D in
2015 and assuming a 2% annual increase, the 11.3-acre Nash County C&DLF is
expected to reach capacity in 2018.
3.2 PROPOSED 15.8-ACRE HORIZONTAL EXPANSION
The proposed 15.8-acre Horizontal Expansion of the existing 11.3-acre Nash County
C&DLF is shown on Sheet 1 of the Engineering Drawings. The proposed 15.8-acre
Horizontal Expansion of the existing 11.3-acre Nash County C&DLF is estimated to
provide an additional 1,620,500 cubic yards gross capacity (i.e. bottom of waste to the
top of final cover elevations), or about 1,543,876 cubic yards of net airspace (i.e.
bottom of waste to the top of waste elevations) beyond the previously permitted top of
waste elevations of the existing 11.3-acre Nash County C&DLF (Phase 1 – 3).
Assuming the proposed 15.8-acre Nash County Horizontal Expansion will continue to
operate at a 745 lbs/CY AUF, the remaining 1,543,876 cubic yards net airspace will
provide 575,000 tons of waste disposal capacity. Based on the assumed 10,000 tons
of C&D to be disposed in 2015, and assuming a 2% annual increase, the combined
27.1-acre Nash County Construction & Demolition Landfill (C&DLF) and Horizontal
Expansion is expected to reach capacity in 2053.
The proposed 15.8-acre Horizontal Expansion of the existing 11.3-acre Nash County
C&DLF is projected to be constructed and operated in nine (9) phases with individual
and cumulative capacities as shown on the Table 1 below.

3.3 SOIL QUANTITIES FOR THE PROPOSED 15.8-ACRE HORIZONTAL
EXPANSION
Subgrade construction for the 15.8-acre Horizontal Expansion requires 262,817 cubic
yards excavation and 29,962 cubic yards backfill, resulting in 232,855 cubic yards
excess.
Daily cover operations for the 15.8-acre Horizontal Expansion is anticipated to require
a 10:1 waste to cover ratio. Therefore, the 1,543,876 cubic yards net airspace is
anticipated to require 140,000 cubic yards daily cover soil.
The 3-foot thick final cover system for the 15.8-acre Horizontal Expansion requires
76,296 cubic yards soil.
Therefore, Subgrade construction provides adequate soil for both daily cover
operations and final cover.

4.0 SPECIAL ENGINEERING FEATURES
Rule 15A NCAC 13B .0537(e)(3) requires a discussion of Special Engineering Features
associated with the proposed facility.
4.1 LEACHATE MANAGEMENT SYSTEMS
No leachate management systems are constructed for current 11.3-acre C&DLF
Facility, nor will they be included in the proposed 15.8-acre Horizontal Expansion.
4.2 CONTAINMENT AND ENVIRONMENTAL CONTROL SYSTEMS
The current Nash County 11.3-acre C&DLF Facility has 6 groundwater monitoring
wells sampled on a semi-annual basis.
The proposed Nash County 15.8-acre Horizontal Expansion will require abandonment
and relocating of groundwater monitoring well MW-6. Additional groundwater
monitoring wells, designated MW-7 and MW-8, will be added per the Monitoring Plan.
4.3 BASE LINER SYSTEM
No base liner systems are constructed or proposed for the current 11.3-acre C&DLF
Facility. A base liner system is not included for the proposed 15.8-acre Horizontal
Expansion.
4.4 OTHER DEVISED, COMPONENTS, AND STRUCTURES
The current Nash County 11.3-acre C&DLF facility has installed erosion and
sedimentation control devices in accordance with the approved Sediment and Erosion
Control Plan which collects stormwater from the C&DLF footprint and channels it to
sediment basins.
The proposed Nash County 15.8-acre Horizontal Expansion requires the approved
Sediment and Erosion Control Plan to be modified, including additional sediment
control devices to direct all stormwater from the expanded C&DLF footprint to routed
sediment basins.

2.1 ANALYTICAL METHODS USED TO EVALUATE THE DESIGN
Analytical methods used to evaluate the design are indicated throughout the
application, as indicated.
2.2 CRITICAL CONDITIONS EVALUATED AND ASSUMPTIONS MADE
Critical conditions evaluated in the design include vertical and horizontal separation
of the proposed 15.8-acre Horizontal Expansion of the existing 11.3-acre Nash County
C&DLF, operability, stability, and other features described throughout the application.
Subgrade settlement is evaluated using the method described by Hough in
“Compressibility as a Basis for Soil Bearing Value,” 1969, ASCE.
Global stability of the filled proposed 15.8-acre Horizontal Expansion of the existing
11.3-acre Nash County C&DLF is evaluated using the Modified Bishop Method.
Calculations for settlement as wells global stability are included in Appendix C.
2.3 TECHNICAL REFERENCES
Technical references utilized in the design are indicated throughout this application.
2.4 LOCATION RESTRICTION DEMONSTRATIONS
New C&DLF unit(s) and lateral expansions must comply with the siting criteria set forth
in Rule 15A NCAC 13B .0536 (c), Subparagraphs (4) through (10).
2.4.1 FLOODPLAIN LOCATION RESTRICTIONS
C&DLF units or constructed embankments used to construct a C&DLF unit must
not be located in a 100-year floodplain unless a variance for the facility has been
issued in accordance with G.S. 143-215.54A.
C&DLF units must not be located in floodplains unless the owners or operators
demonstrate that the unit will not restrict the flow of the flood, reduce the temporary
water storage capacity of the floodplain, or result in washout of solid waste so as
to pose a hazard to human health and the environment.
The proposed facility occurs on Federal Emergency Management Agency (FEMA)
Flood Insurance Rate Map (FIRM) panel 3702782884J. The proposed landfill area
is in Zone X –Areas determined to be outside the 0.2% annual chance floodplain.
Therefore, the proposed 15.8-acre Horizontal Expansion of the existing 11.3-acre
Nash County C&DLF unit is not located in a 100-year flood plain. A copy of the
appropriate FEMA FIRM panel is included on the following page.
ENGINEERING PLAN
NASH COUNTY C&D LANDFILL
AND HORIZONTAL EXPANSION
Page 3 of 9
2.4.2 WETLANDS LOCATION RESTRICTION
New C&DLF units and lateral expansions must not be located in wetlands, unless
the owner or operator can make the following demonstrations to the Division:
(A) Where applicable under Section 404 of the Clean Water Act or applicable
State wetlands laws, the presumption that a practicable alternative to the
proposed landfill facility is available which does not involve wetlands is
clearly rebutted.
(B) The construction and operation of the C&DLF unit(s) will not cause or
contribute to violations of any applicable State water quality standards and
will not violate any applicable toxic effluent standard or prohibition under
Section 307 of the Clean Water Act.
(C) The construction and operation of the C&DLF unit(s) will not jeopardize the
continued existence of endangered or threatened species or result in the
destruction or adverse modification of a critical habitat, protected under the
Federal Endangered Species Act of 1973. The construction and operation
of the C&DLF unit(s) will not violate any requirement under the Marine
Protection, Research, and Sanctuaries Act of 1972 for the protection of a
marine sanctuary.
(D) The construction and operation of the C&DLF unit(s) will not cause or
contribute to significant degradation of wetlands.
(E) The owner or operator must demonstrate the integrity of the C&DLF unit(s)
and its ability to protect ecological resources by addressing the following
factors: (1) erosion, stability, and migration potential of native wetland soils,
muds and deposits used to support the C&DLF unit; (2) erosion, stability,
and migration potential of dredged and fill materials used to support the
C&DLF unit; the volume and chemical nature of the waste managed in the
C&DLF unit; (3) impacts on fish, wildlife, and other aquatic resources and
their habitat from release of the solid waste; (4) the potential effects of
catastrophic release of waste to the wetland and the resulting impacts on
the environment; and (5) any additional factors, as necessary, to
demonstrate that ecological resources in the wetland are sufficiently
protected to the extent required under Section 404 of the Clean Water Act
or applicable State wetlands laws.
(F) The owner or operator must demonstrate that steps have been taken to
attempt to achieve no net loss of wetlands (as defined by acreage and
function) by first avoiding impacts to wetlands to the maximum extent
ENGINEERING PLAN
NASH COUNTY C&D LANDFILL
AND HORIZONTAL EXPANSION
Page 4 of 9
practicable as required by Part (c)(5)(A) – (D) of this Rule, then minimizing
unavoidable impacts to the maximum extent practicable, and finally
offsetting remaining unavoidable wetland impacts through all appropriate
and practicable compensatory mitigation actions (e.g., restoration of
existing degraded wetlands or creation of man-made wetlands).
(G) The owner or operator must also demonstrate that sufficient information is
available to make a reasonable determination with respect to each of the
demonstrations required by this Rule.
(H) For purposes of this Rule, wetlands means those areas that are defined in
40 CFR 232.2(r).
Documentation of the wetland delineation performed for the proposed expansion
is included in Appendix A. The proposed 15.8-acre Horizontal Expansion of the
existing 11.3-acre Nash County C&DLF does not impact delineated wetlands or
associated buffers. Thus, the proposed site has met the requirements of Rule
.0536(c)(5).
2.4.3 UNSTABLE AREA LOCATION RESTRICTIONS.
Owners and operators of new C&DLF unit(s) and lateral expansions proposed for
location in an unstable area must demonstrate that engineering measures have
been incorporated in the C&DLF unit's design to ensure that the integrity of any
structural components of the C&DLF unit will not be disrupted. The owner and
operator must consider the following factors, at a minimum, when determining
whether an area is unstable:
(A) On-site or local soil conditions that may result in significant differential
settling;
(B) On-site or local geologic or geomorphologic features; and
(C) On-site or local human-made features or events (both surface and
subsurface)
No conditions have been identified at the site that would cause the facility to be
unstable.
2.4.4 CULTURAL RESOURCES LOCATION RESTRICTIONS
A new C&DLF unit or lateral expansion must not damage or destroy a property of
archaeological or historical significance which has been listed or determined
eligible for a listing in the National Register of Historic Places. To aid in making a
determination as to whether the property is of archeological or historical
ENGINEERING PLAN
NASH COUNTY C&D LANDFILL
AND HORIZONTAL EXPANSION
Page 5 of 9
significance, the State's Historic Preservation Office in the Department of Cultural
Resources may request the owner and operator to perform a site-specific survey
which must be included in the Site Study.
The North Carolina Department of Cultural Resources was contacted to identify
any archaeological or historical properties which may be damaged or destroyed
due to the construction and demolition landfill. Correspondence from the
Department of Cultural Resources indicated that no properties of architectural,
historic, or archaeological significance would be affected by the project. Thus, the
proposed site has met the requirements of Rule .0536(c)(7). Department of
Cultural Resources correspondence is located in Appendix B.
2.4.5 STATE NATURE AND HISTORIC PRESERVE LOCATION
RESTRICTIONS
A new C&DLF unit or lateral expansion must not have an adverse impact,
considering the purposes for designation of the Preserve lands and the location,
access, size and operation of the landfill, on any lands included in the State Nature
and Historic Preserve.
The proposed 15.8-acre Horizontal Expansion of the existing 11.3-acre Nash
County C&DLF will not have an adverse impact on State Nature and Historic
Preservation areas.
2.4.6 WATER SUPPLY WATERSHEDS LOCATION RESTRICTIONS
(A) A new C&DLF unit or lateral expansion must not be located in the critical
area of a water supply watershed, or in the watershed for a stream segment
classified as WS-I, or in watersheds of other water bodies which indicate
that no new landfills are allowed in accordance with the rules codified at
15A NCAC 02B Section .0200 entitled "Classifications and Water Quality
Standards Applicable To Surface Waters Of North Carolina."
(B) Any new C&DLF unit or lateral expansion, which proposes to discharge
leachate to surface waters and must obtain a National Pollution Discharge
Elimination System (NPDES) Permit from the Division of Environmental
Management pursuant to Section 402 of the United States Clean Water Act,
must not be located within watersheds classified as WS-II or WS-III, or in
watersheds of other water bodies which indicate that no new discharging
landfills are allowed, in accordance with the rules codified at 15A NCAC
02B Section .0200.
The proposed 15.8-acre Horizontal Expansion of the existing 11.3-acre Nash
County C&DLF ultimately drains to Pigbasket Creek, which is designated Class B.
ENGINEERING PLAN
NASH COUNTY C&D LANDFILL
AND HORIZONTAL EXPANSION
Page 6 of 9
No special restrictions exist for Class B streams. The facility does not drain to a
stream designated WS-I, WS-II, or WS-III.
The proposed 15.8-acre Horizontal Expansion of the existing 11.3-acre Nash
County C&DLF is not located in the critical area of a water supply watershed, or in
the watershed for a stream segment classified as WS-I, or in watersheds of other
water bodies which indicate that no new landfills are allowed in accordance with
the rules codified at 15A NCAC 02B Section .0200.
The proposed 15.8-acre Horizontal Expansion of the existing 11.3-acre Nash
County C&DLF will not discharge leachate to surface water bodies, therefore an
NPDES permit will not be required.
2.4.7 ENDANGERED AND THREATENED SPECIES LOCATION
RESTRICTIONS
A new C&DLF unit or lateral expansion must not jeopardize the continued
existence of endangered or threatened species or result in the destruction or
adverse modification of a critical habitat, protected under the Federal Endangered
Species Act of 1973.
Carolina Ecosystems, Inc., performed an assessment of endangered and
threatened species at the facility. As documented in Appendix B, habitat for
federally threatened or endangered species under the protection of the
Endangered Species act is not present on site.
3.0 DESCRIPTION OF THE MATERIALS AND CONSTRUCTION PRACTICES
3.1 HORIZONTAL SEPARATION REQUIREMENTS.
3.1.1 PROPERTY LINE BUFFER.
New C&DLF unit(s) at a new facility must establish a minimum 200-foot buffer
between the C&DLF unit and all property lines for monitoring purposes.
The horizontal separation requirement between the disposal boundary (edge of
waste) and the property lines is a minimum of 200 feet per Section .0540(2) (which
allows a 50- foot buffer for existing operating units).
As shown on Sheet 1 of the Engineering Drawings, the property line buffer is
satisfied with the proposed 15.8-acre Horizontal Expansion of the existing 11.3-
acre Nash County C&DLF.

3.1.2 OFFSITE RESIDENTIAL STRUCTURES AND WELLS
All C&DLF units at a new facility must establish a minimum 500-foot buffer between
the C&DLF unit and existing residential structures and wells.
As shown on Sheet 1 of the Engineering Drawings, The 500-foot buffer horizontal
separation requirement between the disposal boundary (edge of waste) and
private residences and wells and the disposal boundary is satisfied with the
proposed 15.8-acre Horizontal Expansion of the existing 11.3-acre Nash County
C&DLF.
3.1.3 SURFACE WATERS
All C&DLF units at new facilities must establish a minimum 50-foot buffer between
the C&DLF unit and any stream, river, lake, pond or other waters of the state as
defined in G.S. 143-212.
The proposed 15.8-acre Horizontal Expansion of the existing 11.3-acre Nash
County C&DLF does not occur within 50 feet of any stream, river, lake, pond or
other waters of the state.
3.1.4 EXISTING LANDFILL UNITS
A monitoring zone must be established between a new C&DLF unit and any
existing landfill units such as MSW, Industrial, C&DLF, or Land Clearing and Inert
Debris (LCID), in order to establish a ground-water monitoring system as set forth
in Rule .0544 of this Section.
A monitoring zone has been established between the proposed 15.8-acre
Horizontal Expansion of the existing 11.3-acre Nash County C&DLF and the
existing closed MSW landfill unit.
3.2 VERTICAL SEPARATION REQUIREMENTS
C&DLF unit(s) must be constructed so that the post-settlement bottom elevation of
waste is a minimum of four feet above the seasonal high ground-water table and the
bedrock datum plane contours established in the Design Hydrogeological Report
prepared in accordance with Paragraph (b) of Rule .0538 of this Section.
The seasonal high ground-water table is higher than bedrock within the entire area of
the proposed 15.8-acre Horizontal Expansion of the existing 11.3-acre Nash County
C&DLF. Therefore, the seasonal high ground-water table is the design constraint for
vertical separation. The subgrade is closest to the seasonal high ground-water table
bottom of the northern most internal 3:1 side slope as seen in Section A. Calculations
are included in Appendix C demonstrating the maximum settlement within the post-
settlement bottom elevation of waste is approximately four (4) inches. The proposed
ENGINEERING PLAN
NASH COUNTY C&D LANDFILL
AND HORIZONTAL EXPANSION
Page 8 of 9
15.8-acre Horizontal Expansion of the existing 11.3-acre Nash County C&DLF
subgrade has been designed so that the post-settlement bottom elevation of waste is
a minimum of four feet above the seasonal high ground-water table. Therefore The
proposed 15.8-acre Horizontal Expansion of the existing 11.3-acre Nash County
C&DLF base grades meet the minimum requirement of four feet above the seasonal
high groundwater table and bedrock.
3.3 SURVEY CONTROL
One permanent benchmark of known elevation measured from a U.S. Geological
Survey benchmark must be established and maintained for each 50 acres of
developed landfill, or part thereof, at the landfill facility. This benchmark shall be the
reference point for establishing vertical elevation control. Any survey performed
pursuant to this Sub-Item must be performed by a Registered Land Surveyor.
There are currently no permanent benchmarks at the facility. Permanent benchmarks
will be established during the construction of the first phase of the proposed 15.8-acre
Horizontal Expansion of the existing 11.3-acre Nash County C&DLF. The location of
the permanent benchmarks will be provided to NCDENR upon establishment.
3.4 LOCATION COORDINATES
The Latitude and Longitude, expressed in decimal degrees, at the approximate center
of the facility is Latitude 36.06, Longitude -78.01.
3.5 LANDFILL SUBGRADE
The landfill subgrade is the in-situ or modified soil layer(s), constructed embankments,
and select fill providing the foundation for construction of the unit. The landfill
subgrade must be graded in accordance to the plans and specifications prepared in
accordance to Rule .0539 of this Section, which are incorporated into the permit to
construct in accordance with Paragraph (b) of Rule .0534 of this Section as follows:
(A) The owner or operator of the C&DLF unit must have the subgrade inspected
by a qualified geologist or engineer when excavation is completed.
(B) The owner or operator of the C&DLF unit must notify the Division's
hydrogeologist at least 24 hours before subgrade inspection.
(C) Compliance with the requirements of Sub-Item (2)(b) of this Rule must be in
accordance with Paragraph (b) of Rule .0538 of this Section or by placement
of soil in accordance with this Sub-Item and verified in accordance with Rule
.0541 of this Section.
ENGINEERING PLAN
NASH COUNTY C&D LANDFILL
AND HORIZONTAL EXPANSION
Page 9 of 9
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. In addition to
providing the landfill foundation in fill areas, structural fill will be used for berm and
roadway construction. Structural fill will consist of on-site soils removed during
excavation or imported borrow soils, except that no CH, OL, or OH soils will be
allowed.
In addition, it will be field verified as described in the CQA Plan the soils making up
the upper two feet of separation are as specified in the approved construction plan or
have a Unified Soil Classification System of SC, SM, ML, CL,MH or CH.
3.6 SPECIAL ENGINEERING STRUCTURES
No special engineering structures are proposed as part of the C&DLF Expansion.
3.7 SEDIMENTATION AND EROSION CONTROL
Adequate structures and measures must be designed and maintained to manage the
run-on and run-off generated by the 24-hour, 25-year storm event, and conform to the
requirements of the Sedimentation Pollution Control Law (15A NCAC 04) and any
required NPDES permits.
The Erosion and Sedimentation Control structures provided will be designed and
maintained to manage the run-off generated by the 24-hour, 25-year storm event, and
conform to the requirements of the Sedimentation Pollution Control Law (15A NCAC
04). A detailed discussion of site erosion and sedimentation control for the proposed
15.8-acre Horizontal Expansion of the existing 11.3-acre Nash County C&DLF will be
submitted under separate cover.
3.8 CONSTRUCTION QUALITY ASSURANCE (CQA) REPORT
A CQA report must be submitted in accordance with Rule .0541 of this Section. The
CQA Plan for the facility is included as a separate section of this application titled
Construction Quality Assurance (CQA) Plan.

Project Description & Methodology
As shown in Figure 1, the Nash County Landfill project is located in Nash County, NC within
the Tar-Pamlico River Basin (USGS HUC 03020101). The study area consists of the northern
side of the drainage feature adjacent to the proposed landfill expansion area (Figure 4). This
delineation was performed in compliance with methodology set forth in the U.S Army Corps of
Engineers (USACE) Wetland Delineation Manual (USACE 1987) and subsequent guidance
including the Eastern Mountains and Piedmont Regional supplement. Streams were assessed for
jurisdiction under the CWA using field indications of ordinary high water mark and for
jurisdiction under the Tar-Pamlico Buffer rules using the NCDWQ Stream Identification Form,
Version 4.1.1.
Delineation Results
Figure 2 is presented using the following US Geological Survey 1:24,000 quadrangle maps:
Castalia and Red Oak. Figure 3 is presented using the Nash County Soil Survey sheets 3 and 4.
Figure 4 presents the results of the delineation, including approximate stream and wetland

1. The Corps of Engineers believes that there may be jurisdictional waters of the
United States on the subject site, and the permit applicant or other affected party
who requested this preliminary JD is hereby advised of his or her option to
request and obtain an approved jurisdictional determination (JD) for that site.
Nevertheless, the permit applicant or other person who requested this
preliminary JD has declined to exercise the option to obtain an approved JD in
this instance and at this time.
2. In any circumstance where a permit applicant obtains an individual permit, or
a Nationwide General Permit (NWP) or other general permit verification requiring
“pre-construction notification” (PCN), or requests verification for a non-reporting
NWP or other general permit, and the permit applicant has not requested an
approved JD for the activity, the permit applicant is hereby made aware of the
following: (1) the permit applicant has elected to seek a permit authorization
based on a preliminary JD, which does not make an official determination of
jurisdictional waters; (2) that the applicant has the option to request an approved
JD before accepting the terms and conditions of the permit authorization, and
that basing a permit authorization on an approved JD could possibly result in less
compensatory mitigation being required or different special conditions; (3) that
the applicant has the right to request an individual permit rather than accepting
the terms and conditions of the NWP or other general permit authorization; (4)
that the applicant can accept a permit authorization and thereby agree to comply
with all the terms and conditions of that permit, including whatever mitigation
requirements the Corps has determined to be necessary; (5) that undertaking
any activity in reliance upon the subject permit authorization without requesting
an approved JD constitutes the applicant’s acceptance of the use of the
preliminary JD, but that either form of JD will be processed as soon as is
practicable; (6) accepting a permit authorization (e.g., signing a proffered
individual permit) or undertaking any activity in reliance on any form of Corps
permit authorization based on a preliminary JD constitutes agreement that all
wetlands and other water bodies on the site affected in any way by that activity
are jurisdictional waters of the United States, and precludes any challenge to
such jurisdiction in any administrative or judicial compliance or enforcement
action, or in any administrative appeal or in any Federal court; and (7) whether
the applicant elects to use either an approved JD or a preliminary JD, that JD
will be processed as soon as is practicable. Further, an approved JD, a proffered
individual permit (and all terms and conditions contained therein), or individual
permit denial can be administratively appealed pursuant to 33 C.F.R. Part 331,
and that in any administrative appeal, jurisdictional issues can be raised (see 33
C.F.R. 331.5(a)(2)). If, during that administrative appeal, it becomes necessary
to make an official determination whether CWA jurisdiction exists over a site, or
to provide an official delineation of jurisdictional waters on the site, the Corps will
provide an approved JD to accomplish that result, as soon as is practicable.
This preliminary JD finds that there “may be” waters of the United States on the
subject project site, and identifies all aquatic features on the site that could be
affected by the proposed activity, based on the following information:

ENDANGERED SPECIES AND CULTURAL RESOURCES EVALUATION
From:Phil May
To:Craig Fortner
Subject:Nash County Landfill
Date:Friday, August 08, 2014 2:13:45 PM
Craig,
In regard to the Nash County Landfill expansion, in our professional opinion the project will have no
effect on federally listed threatened or endangered species. The following is the US Fish and
Wildlife Service list of species potentially occurring in Nash County (as of July 2014):
- Bald Eagle – No nest trees or eagles were noted on site during initial habitat assessments in
2010 and the delineation in 2013.
- Red-cockaded woodpecker – No RCW nesting or foraging habitat (suitably aged pine stands)
were found within the project limits during habitat assessments performed in 2010. RCW is
listed as a historic (over 50 year old) occurrence by USFWS in Nash Co.
- Tar River spiny mussel and dwarf wedgemussel – No surveys were done for these species
however Pig Basket Creek is impounded by beaver on the site and therefore not suitable
habitat adjacent to the landfill expansion. As no impacts to surface waters are proposed
and appropriate sediment and erosion control measures will be implemented, there should
be no effect on these species.
A review of the North Carolina Natural Heritage Element Occurrence Database, last updated in July
2014, shows that there are no recorded occurrences of federally listed species within the landfill
property or a 2-mile radius. Since no occurrences and no habitat are present, and no effect on the
listed species is anticipated, consultation with the US Fish and Wildlife Service is not required. Let
me know if you have any questions.
Thanks
Phil

6.0 WASTE SCREENING
6.1 TRAINING AND DOCUMENTATION OF WASTE SCREENING PERSONNEL
Waste screening personnel trained in the following areas:
• methods for identification and determination of prohibited wastes, including, but
not limited to, regulated hazardous waste, liquid waste, PCBs and banned
items.
• handling procedures for prohibited wastes,
• record keeping requirements of the program, and
OPERATION PLAN
NASH COUNTY C&D LANDFILL
AND HORIZONTAL EXPANSION
Page 5 of 18
• occupational health and safety.
Documentation of training procedures should include:
1. Date of training
2. A statement asserting that the training included:
A. Recognition of regulated hazardous waste, liquid waste, PCBs and
banned items.
B. Hazardous waste safety precautions as required by the hazardous
waste contingency plan.
3. Written acknowledgement of training by facility personnel.
6.2 NON-DOCUMENTED WASTE SCREENING
Non-documented waste screening to ensure that hazardous or unacceptable wastes
are not disposed in the landfill will be the responsibility of all employees. Each
employee will observe vehicles entering the Facility for any potentially prohibited
waste and will alert management personnel if any prohibited wastes are suspected.
Non-documented waste screening for incoming loads of waste shall be accomplished
as follows:
• Facility Entrance – Only authorized vehicles and material will be allowed
beyond the scales. The scale attendant will refuse entry to any prohibited
vehicles or vehicles observed carrying prohibited waste.
• Waste Discharge Checkpoints – All incoming loads of waste will be observed
by the Facility operators as it is discharged from the waste transport vehicle.
• Active Face Checkpoints – Material will be inspected by the landfill operations
equipment operator(s) as it is incorporated and compacted at the active face.
6.3 DOCUMENTED RANDOM LOAD WASTE SCREENING
In addition to non-documented waste screening performed by the equipment
operator/attendants, a documented random load waste screening program shall be
implemented to detect and prevent disposal of any of the prohibited wastes listed in
previously. Random load waste screening Inspections conducted as part of this
program shall be performed by personnel trained in the following areas:
• methods for identification and determination of prohibited wastes,
• handling procedures for prohibited wastes,
• record keeping requirements of the program, and
OPERATION PLAN
NASH COUNTY C&D LANDFILL
AND HORIZONTAL EXPANSION
Page 6 of 18
• occupational health and safety.
The frequency of the random inspections shall be determined by the quantity and type
of waste received, the familiarity with the generators and/or transporters, and the
occurrences of identified prohibited waste. Inspections should be performed at least
once per week. In order for the waste screening inspections to be random, the time
of day, day of week, and transporter/hauler selected for inspection shall also vary
between inspections. The procedure for the random load waste screening shall be as
follows:
• Stop the selected vehicle prior to the working face of the landfill.
• Notify the driver of the inspection.
• Direct the vehicle to the inspection area. The inspection area may be either
a permanently designated location or a temporary location adjacent to the
working face.
• If possible, perform a visual observation of the waste prior to unloading. If
prohibited waste is observed, or suspected, the vehicle shall be prohibited
from unloading, and shall be directed out of the facility.
• If no prohibited waste is observed or suspected from the visual observation,
or if a visual observation is not possible, the vehicle shall discharge the load
at the inspection area. The driver shall remain at the inspection area while
the inspection is performed, unless a safety concern requires evacuation of
the area. Equipment shall be used to spread and turn the waste to facilitate
a visual observation of the load contents. If no prohibited waste is identified,
the waste shall be transferred to the working face for disposal.
• If prohibited waste is identified in the load, and the prohibited waste is not a
regulated hazardous waste, a regulated medical waste, a regulated toxic
waste, a regulated liquid waste, or a waste which requires special handling,
the waste shall be loaded back into the vehicle and removed from the
facility.
• If acceptability of the waste cannot be determined by visual observation, the
waste can either be rejected and loaded back into the vehicle and removed
from the facility, or samples of the waste can be taken to determine
acceptability. Testing shall be selected based on the reason for the
suspicion of unacceptability.
• If the waste is suspected of being a liquid waste, a regulated hazardous
waste, a regulated medical waste, or a regulated toxic waste, site personnel
OPERATION PLAN
NASH COUNTY C&D LANDFILL
AND HORIZONTAL EXPANSION
Page 7 of 18
will safely identify the nature of the prohibited waste. Wastes within these
categories are not to be handled by landfill staff. Upon assessment of the
waste, qualified contractors will be contacted to provide direction for
temporary handling, isolation, and security. Within 24 hours of discovery,
the Facility will orally inform NCDENR Division of Waste Management
(Division) of the incident and make every effort to contact a waste contractor
for the proper packaging, removal, and disposal of the prohibited waste.
The Division will be informed in writing of the incident and steps taken to
properly dispose of the prohibited waste.
• Complete the waste screening form and place in the operating record.
6.4 CONTINGENCY PLAN
In the event that identifiable hazardous waste or waste of questionable character is
detected at the landfill, appropriate equipment, protective gear, personnel, and
materials as necessary will be employed to isolate the wastes. The DWM will be
notified immediately that an attempt was made to dispose of hazardous waste at the
landfill. If the vehicle attempting disposal of such waste is known, all attempts will be
made to prevent that vehicle from leaving the site or, if the vehicle has left the site,
immediate notice will be served on the owner of the vehicle that hazardous waste, for
which they have responsibility, has been disposed of at the landfill.
Nash County C&D Landfill will assist the DWM as necessary and appropriate in the
removal and disposition of the hazardous waste and in the prosecution of responsible
parties. If needed, the hazardous waste will be covered with either on-site soils or
other tarping material until such time when an appropriate method can be
implemented to properly handle the waste. The cost of the removal and disposing of
the hazardous waste will be charged to the owner of the vehicle involved. Any vehicle
owner or operator who knowingly dumps hazardous waste in the landfill may be barred
from using the landfill. Should an incident where hazardous waste is found at the
landfill occur, the event will be documented by landfill staff using the waste screening
form provided in Appendix A.
Records of information gathered as part of the waste screening programs will be
maintained at the landfill site during its active life and as long as required by Nash
County C&D Landfill and the DWM.
6.5 WASTE SCREENING RECORD KEEPING
The following records must be maintained in the operating record:
• Training Certification recognized and approved by the Department, for all
applicable personnel. Outline of training of each facility personnel to

7.3 ACCESS ROADS
The access road through the facility to the landfill and access roads to monitoring
locations are constructed to provide all-weather traffic. Internal roads are maintained
in good condition to provide operation in all-weather scenarios. Access roads will be
graded for positive drainage. To not impound water, depressions or potholes occurring
shall be addressed swiftly by grading or application of additional stone as necessary
to achieve positive drainage off the road.
The location of access roads during waste placement will be determined by operations
personnel in order to reflect waste placement strategy.
7.4 ENTRANCE SIGNAGE
A sign is located at the Facility entrance containing the hours during which the site is
open for public use, the permit number, a list of prohibited wastes such as liquid,
hazardous and municipal solid waste as being excluded from the C&DLF unit, and
other pertinent information specified in the permit conditions.
7.5 TRAFFIC SIGNAGE
Signs are positioned at the Facility providing information on disposal procedures and
directions to and from the Yard Waste Management Area, White Goods Area, and
C&D landfill Working face. The use of portable signs with directional arrows and
portable traffic barricades will facilitate the unloading of wastes to the designated
disposal locations. These signs and barricades will be placed along the access route
to the working face of the landfill or other designated disposal areas which may be
established. Speed limits are posted throughout the access road to the disposal unit.
7.6 DUST CONTROL
Operations shall endeavor to maintain internal roads free of dust. Typically, a road
truck with rear mounted water tank will be used.
8.0 DISEASE VECTOR CONTROL
Owners and operators of all C&DLF units must prevent or control on-site populations of
disease vectors using techniques appropriate for the protection of human health and the
environment. For purposes of this item, "disease vectors" means any rodents, flies,
mosquitoes, or other animals or insects, capable of transmitting disease to humans.
The Operator will endeavor to prevent and control on-site populations of disease vectors
such as rodents, flies, mosquitoes, or other animals or insects, using techniques
appropriate for the protection of human health and the environment. Specifically, the
Operator will:
• Prevent depressions or low areas susceptible to ponding of water;

10.0 EROSION AND SEDIMENTATION CONTROL REQUIREMENTS
Adequate sediment control measures consisting of vegetative cover, materials, structures
or devices must be utilized to prevent sediment from leaving the C&DLF facility.
Erosion control measures shall include, but not be limited to the following:
(A) Disturbing as little area as practical at any one time for landfilling operations.
(B) Seeding and mulching of all disturbed areas commencing as soon as practically
possible. Employing erosion netting or sod on steep slopes and other erosion
prone areas.
(C) Use of earthen berms, hay bales, silt fences, riprap or equivalent devices down-
gradient of disturbed areas, stockpiles, around drainage pipes inlets and outlets
and at intervals along grassed waterways, until such time as permanent
vegetation is established.
(D) Placement of riprap at the outlets of storm water piping sedimentation pond
discharge pipes.
Provisions for a vegetative ground cover sufficient to restrain erosion must be
accomplished as directed by appropriate state or local agency upon completion of any
phase of C&DLF development consistent with Rule .0543(c)(5).
11.0 LANDFILL OPERATIONS
Loads identified at the scalehouse to contain C&D will be directed to the C&D landfill
working face.
11.1 INITIAL WASTE PLACEMENT
Nash County anticipates constructing the Horizontal Expansion of the Nash County
C&D Landfill in multiple phases. The first phase of construction for the Horizontal
Expansion of the Nash County C&D Landfill will consist of Phase 4 as shown on the
Facility Plan in the Engineering Drawings. Development of subsequent phases is
anticipated to be sequential as shown on the Facility Plan.
11.2 WORKING FACE
The width and length of the working face will be maintained as small as practical in
order to maintain the appearance of the site, control windblown waste, and minimize
the amount of cover required each day. Normally, only one working face will be active
on any given day, with all deposited waste in other areas covered by either periodic,
intermediate, or final cover, as appropriate.
OPERATION PLAN
NASH COUNTY C&D LANDFILL
AND HORIZONTAL EXPANSION
Page 12 of 18
The approach to the working face will be maintained such that two or more vehicles
may safely unload side by side. A vehicle turn-around area large enough to enable
vehicles to arrive and turn around safely with reasonable speed will be provided
adjacent to the unloading area.
Waste transportation vehicles will arrive at the working face at random intervals.
Personnel will direct traffic necessary to expedite safe movement of vehicles. There
may be a number of vehicles unloading waste at the same time, while other vehicles
are waiting. In order to maintain control over the unloading of waste, a certain number
of vehicles will be allowed on the working face at a time. The actual number will be
determined by the truck spotter. This procedure will be used in order to minimize the
potential of unloading unacceptable waste and to control disposal activity. Operations
at the working face will be conducted in a manner which will encourage the efficient
movement of transportation vehicles to and from the working face, and to expedite the
unloading of waste.
The vehicles will back to a vacant area near the working face to unload. Upon
completion of the unloading operation, the transportation vehicles will immediately
leave the working face area.
The general public is prohibited from removal activities on the working face. In
addition, landfill staff will not remove waste (for recycling or recovery) at the working
face.
11.3 SPREADING AND COMPACTING REQUIREMENTS
The Owner of the C&DLF shall comply with spreading and compacting requirements
as follows:
(1) C&DLF units must restrict solid waste into the smallest area feasible.
(2) Solid waste must be compacted as densely as practical into cells.
(3) Appropriate methods such as fencing and diking must be provided within
the area to confine solid waste which is subject to be blown by the wind. At
the conclusion of each operating day, all windblown material resulting from
the operation must be collected and disposed of by the owner and operator.
The Owner will make available durable equipment that performs reliably and safely
with a minimum unscheduled service, equipment to provide suitable material handling
capability and compaction for the given waste volumes anticipated. At minimum, one
(1) 70,000-pound plus machine with a waste handling arrangement and toothed
compactor wheels will be available at the working face at all times.
OPERATION PLAN
NASH COUNTY C&D LANDFILL
AND HORIZONTAL EXPANSION
Page 13 of 18
The procedures for placement and compaction of solid waste include: unloading of
vehicles, spreading of waste into 2 foot lifts, and compaction on relatively flat slopes
(i.e. 5H:1V max.) using a landfill compactor and a minimum number of three full
passes.
11.4 SPECIAL WASTE MANAGEMENT
Nash County C&D Landfill may dispose of asbestos within the C&D landfill unit.
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 in
vehicles that contain only the asbestos waste and only after 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 operations 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 stockpiled will be sufficient to
cover the waste and to provide any berms, etc. to maintain temporary separation from
other landfill traffic.
Once placed in the prepared area, the asbestos waste will be covered with a minimum
of 18 inches of cover soil placed in a single lift. The surface of the cover soil will be
compacted and graded using a tracked 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 record the approximate location and elevation of the asbestos
waste once cover is in-place. The Landfill Manager will then review pertinent disposal
and location information to assure compliance with regulatory requirements and enter
the information into the Operating Record.
Once disposal and recording for asbestos waste is completed, the disposal area may
be covered with waste. No excavation into designated asbestos disposal areas will be
permitted.
11.5 YARD WASTE MANAGEMENT
Nash County accepts yard waste at the designated Yard Waste Management Area
indicated on the overall facility plan in the Engineering Drawings. The yard waste
material accepted by Nash County consists primarily of tree debris and land clearing
debris. High nitrogen yard waste such as grass clippings, leaves, and bush trimmings,
while accepted at the Nash County Landfill, represents an insignificant portion of the
OPERATION PLAN
NASH COUNTY C&D LANDFILL
AND HORIZONTAL EXPANSION
Page 14 of 18
waste stream, and is distributed throughout the yard waste stockpiles. Composting of
yard waste is not performed at the Nash County Landfill.
Nash County contracts grinding services as necessary to maintain stockpiles no larger
than 30 feet high and 50 feet wide of unlimited length. Ground materials are also
maintained in stockpiles no larger than 30 feet high and 50 feet wide of unlimited
length. A minimum of 20 feet shall be maintained between individual stockpiles to
facility firefighting equipment access. Stockpiles are managed to not create excessive
temperatures, attract vectors, or produce objectionable odors.
Ground yard waste materials are offered not offered to the public. Ground materials
are sold for boiler fuel as market conditions permit.
11.6 WHITE GOODS MANAGEMENT
Nash County accepts white goods at the designated white goods area indicated on
the overall facility plan in the Engineering Drawings. Nash County’s White Goods
Plan is included in Appendix B.
11.7 WASTE TIRES
Nash County accepts waste tires at the designated area indicated on the overall
facility plan in the Engineering Drawings.
11.8 COVER MATERIAL REQUIREMENTS
The Owner of the C&DLF shall comply with cover material requirements as follows:
(1) Except as provided in Subparagraph (3) of this Paragraph, the owners and
operators of all C&DLF units must cover the solid waste with six inches of
earthen material when the waste disposal area exceeds one-half acre and at
least once weekly. Cover must be placed at more frequent intervals if
necessary to control disease vectors, fires, odors, blowing litter, and
scavenging. A notation of the date and time of the cover placement must be
recorded in the operating record as specified in Paragraph (n) of this Rule.
(2) Except as provided in Subparagraph (3) of this Paragraph, areas which will not
have additional wastes placed on them for three months or more, but where
final termination of disposal operations has not occurred, must be covered and
stabilized with vegetative ground cover or other stabilizing material.
(3) Alternative materials or an alternative thickness of cover may be approved by
the Division if the owner or operator demonstrates that the alternative material
or thickness controls disease vectors, fires, odors, blowing litter, and
scavenging without presenting a threat to human health and the environment.
OPERATION PLAN
NASH COUNTY C&D LANDFILL
AND HORIZONTAL EXPANSION
Page 15 of 18
A C&DLF owner or operator may apply for approval of an alternative cover
material. If approval is given by the Division, approval would extend to all
C&DLF units at one specific facility.
Nash County plans to utilize Alternative Daily Cover (ADC) consisting of
Soil/Mulch Mixture (S&M) mixed at a ratio 50% soil to 50% mulch by volume
per DENR guidance document “APPROVED ALTERNATIVE DAILY COVER
MATERIALS FOR USE AT SANITARY LANDFILLS”, Document Number
20365, dated January 7, 2014. Specifically:
1. S&M can be mixed at a ratio from 80% soil to 20% mulch up to 50% soil
to 50% mulch by volume.
2. During the use of S&M as an ACM, soil cover to a full depth of six inches
shall be applied once per week.
3. S&M may not be used for intermediate cover.
A copy of the APPROVED ALTERNATIVE DAILY COVER MATERIALS
FOR USE AT SANITARY LANDFILLS”, Document Number 20365,
dated January 7, 2014 shall be placed in the operating record.
11.9 DRAINAGE CONTROL AND WATER PROTECTION REQUIREMENTS
Drainage control and water protection at the facility will consist of the following:
(1) Surface water must be diverted from the operational area.
(2) Surface water must not be impounded over or in waste.
(3) Solid waste must not be disposed of in water.
(4) Leachate must be contained on-site or treated prior to discharge. An
NPDES permit may be required prior to the discharge of leachate to surface
waters.
(5) C&DLF units must not:
(A) Cause a discharge of pollutants into waters of the United States,
including wetlands, that violates any requirements of the Clean
Water Act, including the National Pollutant Discharge Elimination
System (NPDES) requirements, pursuant to Section 402.
(B) 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
OPERATION PLAN
NASH COUNTY C&D LANDFILL
AND HORIZONTAL EXPANSION
Page 16 of 18
has been approved under Section 208 or 319 of the Clean Water Act,
as amended.
Waste placement will be performed in a planned sequence to divert stormwater from
the operational area (working face) and so that stormwater shall not be impounded in
the waste or over any covered area. Depressions in the waste mass shall be
addressed with placement of additional cover soil.
The design for the Nash County C&DLF and Horizontal Expansion includes drainage
ditches as well as four sediment control ponds which are designed to capture
sediment laden runoff from unstablized landfill areas prior to discharge to surrounding
discharge features.
Runoff from areas with well-established vegetation are not required to be routed
through the sediment control ponds.
11.10 SEVERE WEATHER CONDITIONS
Unusual weather conditions can directly affect the operation of the landfill facility.
Some of these weather conditions and recommended operational responses are as
follows.
11.10.1 ICE STORMS
An ice storm can make access to the landfill dangerous, prevent movement or
placement of daily cover, and, thus, may require closure of the landfill until the ice
is removed or has melted.
11.10.2 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-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.
11.10.3 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.
OPERATION PLAN
NASH COUNTY C&D LANDFILL
AND HORIZONTAL EXPANSION

To guarantee the safety of all field personnel, refuge will be taken in the on-site
buildings or in rubber-tired vehicles.
11.10.4 WINDY CONDITIONS
Wind screens adjacent to the working face may be used as required to control
windblown waste.
11.10.5 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.
11.11 SURVEY FOR COMPLIANCE
Within 60 days of the permittee's receipt of the Division's written request, the permittee
must cause to be conducted a survey of active or closed portions of unit or units at the
facility in order to determine whether operations are being conducted in accordance
with the approved design and operational plans. The permittee must report the results
of such survey, including a map produced by the survey, to the Division within 90 days
of receipt of the Division's request.
(1) A survey shall be required by the Division:
(A) If there is reason to believe that operations are being conducted in
a manner that deviates from the plan listed in the effective permit,
or;
(B) As a verification that operations are being conducted in accordance
with the plan listed in the effective permit.
(2) Any survey performed pursuant to this Paragraph must be performed by
a registered land surveyor duly authorized under North Carolina law to
conduct such activities
12.0 OPERATING RECORD AND RECORDKEEPING REQUIREMENTS

INTRODUCTION
During the 2013 session of the North Carolina General Assembly, Session Law 2013-413 was passed
which amended North Carolina General Statute (NCGS) 130A-295.6 concerning the use of alternative
cover materials (ACM) as daily cover at sanitary landfills. The statute states that once an ACM has
been approved for use by the Department of Environment and Natural Resources (NCDENR) at any
sanitary landfill in North Carolina, it may be used at all sanitary landfills within the state.
The Solid Waste Section (Section) of the NCDENR Division of Waste Management prepared this
guidance document to assist the regulated community in the implementation of the statue. Section
staff developed an inventory of ACM approved for use in North Carolina and the summarized the
approved operational conditions and application processes for use of the ACM. This information,
along with instructions on how to add the use of previously approved ACM to a sanitary landfill
operation and permit, is provided.
REGULATORY AUTHORITY AND INTERPRETATION
Industrial waste landfills (IndLF), construction and demolition solid waste landfills (C&DLF), and
municipal solid waste landfills (MSWLF) are all considered sanitary landfills by North Carolina statutes
and rules.
Previously there was no statutory language regarding daily cover, alternative daily cover or
alternative cover materials. However, cover requirements and alternatives based on specific types of
sanitary landfills were addressed in the Solid Waste Management Rules - Title 15A Chapter 13, Sub-
chapter B of the North Carolina Administrative Code (15A NCAC 13B). The following rule references
provide the current requirements which can affect the use of an ACM at a specific type of sanitary
landfill.
Industrial waste landfills are permitted and operated under Sections .0503, .0504, .0505 and .0510 of
the NCAC.
Part .0505(3)(a) specifically states: Solid waste shall be covered after each day of operation,
with a compacted layer of at least six inches of suitable cover or as specified by the Division.
C&D waste landfills are currently permitted and operated under Sections .0531 through .0547 of the
NCAC.
Part .0542(f)(1) states: Except as provided in Subparagraph (3) of this Paragraph, the owners
and operators of all C&DLF units must cover the solid waste with six inches of earthen material
when the waste disposal area exceeds one-half acre and at least once weekly. Cover must be
placed at more frequent intervals if necessary to control disease vectors, fires, odors, blowing
APPROVED ALTERNATIVE DAILY COVER MATERIALS Page 2
January dd, 2014 – DIN nnnnn
litter, and scavenging. A notation of the date and time of the cover placement must be
recorded in the operating record as specified in Paragraph (n) of this Rule.
Part .0542(f)(3) states: Alternative materials or an alternative thickness of cover may be
approved by the Division if the owner or operator demonstrates that the alternative material
or thickness controls disease vectors, fires, odors, blowing litter, and scavenging without
presenting a threat to human health and the environment. A C&DLF owner or operator may
apply for approval of an alternative cover material. If approval is given by the Division,
approval would extend to all C&DLF units at one specific facility.
MSW landfills are currently permitted and operated under Sections .1601 through .1680 of the NCAC.
Part .1626(2)(a) states: Except as provided in Sub-Item (b) of this Item, the owners or
operators of all MSWLF units must cover disposed solid waste with six inches of earthen
material at the end of each operating day, or at more frequent intervals if necessary, to
control disease vectors, fires, odors, blowing litter, and scavenging.
Part .1626(2)(b) states: Alternative materials of an alternative thickness (other than at least
six inches of earthen material) may be approved by the Division if the owner or operator
demonstrates that the alternative material and thickness control disease vectors , fires , odors
, blowing litter, and scavenging without presenting a threat to human health and the
environment, in accordance with 40 CFR Part 258.21. A MSWLF owner or operator may apply
for a generic approval of an alternative cover material, which would extend to all MSWLF
units.
IMPLEMENTATION
The use of an ACM must be documented in the approved operation plan for the facility. If a facility
intends to utilize an ACM that is currently not in their approved operation plan but is included in the
ACM summary, they may do so by following one of the following procedures:
1. The facility may elect to use an approved ACM in the manner prescribed in this document. To
implement the use of the ACM, the facility owner or operator should place a notice in the facility
operating record with the procedure for using the ACM according to the information in this
document and send a copy of the notice and procedure to the Permitting Branch Supervisor of the
Section and the facilities Environmental Senior Specialist (ESS). The ADC must be incorporated into
the facility operation plan and will be listed in the permit at the next permit action.
2. The facility may choose to implement an ACM that has been approved in a manner not
prescribed in this document by performing an abbreviated demonstration period. This will allow the
operator to tailor the ACM to their specific use, staff, and facility operation. The Section will provide
oversight and concurrence to the process. The owner or operator should contact their (ESS) to discuss
APPROVED ALTERNATIVE DAILY COVER MATERIALS Page 3
January dd, 2014 – DIN nnnnn
the specifications for the testing. At the conclusion of the process, a notice should be placed in the
facility operating record with the procedure for using the ACM and a copy of the notice and
procedure sent to the Permitting Branch Supervisor of the Section. At the next permit action, the
ACM must be incorporated into the facility operation plan and will be listed in the permit.
If a facility wishes to use an ACM that has not previously been approved by the Section, the operator
must complete a demonstration process. Contact your ESS for assistance.
COMPLIANCE
Regardless of the method chosen, the Section will ensure compliance with the proper use of the ACM
in accordance with the rules, statutes, site specific conditions, and historical precedent. An operator
who chooses to implement an ACM as described in choice 1 above will be immediately responsible
for compliance and subject to the NCDENR tiered-enforcement process. An operator who chooses
option 2 will be subject to enforcement that considers the demonstration nature of the action, with
the understanding that changes to the process or ACM will be instituted immediately to correct any
issues.

b. Placed on the working face to a minimum depth of 3” and then covered with soil a
minimum depth of 3” if it can become airborne or exhibits dust like properties.
3. During the use of CR/Ash as an ACM, soil cover to a full depth of six inches shall be applied
once per week, unless otherwise approved by the Section*.
4. CR/Ash may not be used for intermediate cover, if it can become airborne or exhibits dust like
properties.
5. The CR/Ash must be sourced from within the approved service area of the landfill facility.
Warning: Some materials such, as flue gas desulfurization residue, are destined for recycle and
cannot be contaminated with soil. Site specific handling practices should be discussed with the
Solid Waste Section prior to implementation.
* A CDLF or IndLF equipped with a liner system may use the CR as alternate daily cover only. Use of
more than six inches equates to disposal. CR is not a C&D waste. To dispose of CR in a lined CDLF,
or a non-CCB industrial landfill, contact the Permitting Branch of the Solid Waste Section for
further clarification.

1.04 QUALITY ASSURANCE
A. Owner shall employ a CQA Officer and Quality Assurance Laboratory to perform
soils observation and testing services for quality assurance of the fill material.
1.05 PROTECTION
A. Sheeting and Bracing (if required)
1. Furnish, put in place and maintain such sheeting and bracing as may be
required by Federal, State and local safety requirements to support the
sides of excavations; to prevent any movement which could in any way
diminish the width of the excavation below that necessary for proper
construction; and to protect adjacent structures from undermining or other
damage. If the Engineer is of the opinion that at any location sufficient or
proper supports have not been provided, he/she may order additional
supports put in, and compliance with such order shall not relieve or
release the Contractor from his/her responsibility for the sufficiency of
such supports. Care shall be taken to prevent voids outside of the
sheeting, but if voids are formed, they shall be immediately filled and
rammed. Where soil cannot be properly compacted to fill a void, lean
concrete shall be used as backfill. All voids shall be filled to the
satisfaction of the CQA Officer.
2. Construct the sheeting outside the neat lines of the foundation, unless
indicated otherwise, to the extent deemed desirable for the method of
operation. Sheeting shall be plumb and securely braced and tied in
position. Sheeting and bracing shall be adequate to withstand all
pressures to which the structure or trench will be subjected. Any
movement or bulging which may occur shall be corrected to provide the
necessary clearances and dimensions.
3. All sheeting and bracing shall be carefully removed in such manner as not
to endanger the construction or other structures, utilities, or property. All
voids left or caused by withdrawal of sheeting shall be immediately re-filled
with sand, which must be approved by the CQA Officer, by ramming with
tools especially adapted to that purpose, or otherwise as may be directed.
October 2016
02200-3
4. The right of the CQA Officer to order sheeting and bracing left in place
shall not be construed as creating any obligation on his/her part to issue
such orders and his/her failure to exercise his/her right to do so shall not
relieve the Contractor from liability for damages to persons or property
occurring from or upon the work occasioned by negligence or otherwise,
growing out of a failure on the part of the Contractor to leave in place
sufficient sheeting and bracing to prevent any caving or moving of the
ground.
5. No sheeting is to be withdrawn if driven below mid-diameter of any pipe
and under no circumstances shall any sheeting be cut off at a level lower
than 1-ft above the top of any pipe.
B Drainage and De-watering
1. Dewatering shall be performed as specified during the excavation of
organics and unstable soils from the site. Limited dewatering may be
required during the excavation and filling of ponds, ditches and where the
topsoil layer extends below the water table.
2. At all times during construction provide and maintain proper equipment
and facilities to remove all water entering excavations and keep such
excavations dry so as to obtain a satisfactory undisturbed subgrade
condition until the fills, structures or pipes to be built thereon have been
completed to such extent that they will not be floated or otherwise
damaged by allowing water into the excavated areas. Groundwater shall
be lowered to at least 1 foot below the bottom of excavations.
3. De-watering shall at all times be conducted in such a manner as to
preserve the undisturbed bearing capacity of the subgrade soils at
proposed bottom of excavation. Well or sump installations shall be
constructed with proper sand filters to prevent drawing of finer grained soil
from the surrounding ground.
4. Surface runoff shall be collected, drained to sumps and pumped from the
disposal unit to maintain an excavation bottom free from standing water.
5. De-watering of ponds or ditches filled with water shall be performed in
such a manner as to control discharge water by use of sediment basins
and/or check dams or other erosion control structures approved by
NCDENR.
6. Take all additional precautions to prevent uplift of any structure during
construction.
7. Drainage shall be disposed of so that flow or seepage back into the
excavated area will be prevented.
October 2016
02200-4
8. Flotation shall be prevented by maintaining a positive and continuous
operation of the dewatering system. The Contractor shall be fully
responsible and liable for all damages which may result from failure of this
system.
9. Remove the dewatering equipment after the system is no longer required.
10. Take all necessary precautions to preclude the accidental discharge of
fuel, oil, etc in order to prevent adverse effects on groundwater or surface
water quality.
C. SLOPE STABILITY
1. The Contractor shall be solely responsible for the stability of roadway
embankments, unbalanced fills, stockpiles, and all other construction
operations.

One-point compaction tests shall be performed to interpolate between
laboratory compaction (ASTM D 698) curves for at least every 5 in-place
density tests or per change in material. The one-point compaction tests shall
be performed on either the field density test sample or soil from a location
immediately adjacent to the field density test sample, using the ASTM D 698
procedure. The results of the one-point tests shall then be compared with the
full compaction curves of similar soils to estimate the maximum dry density
applicable to the field density test sample.
Note: A nuclear density test gauge can be used to provide the required
density testing. However, the in-situ density shall be determined using the
sand cone method (ASTM D 1556) and/or the drive cylinder method
(ASTM D 2937) of a minimum of one test per ten nuclear density tests or
one per day, whichever is greater. The sand cone and/or drive cylinder
test should be performed at the same location as a nuclear density test.
The sand cone and/or drive cylinder tests shall be continued until a
correlation between the density and moisture contents obtained by the
nuclear density gauge and the sand cone and/or drive cylinder tests has
been demonstrated.

GAS CONTROL PLAN
Rule 15A NCAC 13B .0544 (d) requires a gas control plan that ensures:
(A) The concentration of methane gas or other explosive gases generated by the facility
does not exceed 25 percent of the lower explosive limit (LEL) in on-site facility
structures (excluding gas control or recovery system components).
(B) The concentration of methane gas or other explosive gases does not exceed the lower
explosive limit for methane or other explosive gases at the facility property boundary;
and
(C) The facility does not release methane gas or other explosive gases in any
concentration that can be detected in offsite structures.
Routine Monitoring Plan
Rule 15A NCAC 13B .0544 (d)(2) requires owners and operators of C&DLF units to implement a
routine gas control monitoring program to ensure that the explosive gas concentration standards
are met. Table 1 shows the coordinates of landfill gas monitoring wells associated with Horizontal
Expansion of the Nash County C&D Landfill. Figure 1 shows the locations of landfill gas
monitoring wells associated with Horizontal Expansion of the Nash County C&D Landfill. The
landfill gas monitoring wells are located based on soil conditions, the hydrogeologic conditions
under and surrounding the facility, hydraulic conditions on and surrounding the facility, the location
of facility structures and property boundaries, and the location of all off-site structures adjacent to
property boundaries.
The landfill gas monitoring wells shall be monitored quarterly.
Explosive Gas Concentration Limits
The operator shall ensure that the concentration of explosive gases generated by the facility does
not exceed 25% of the corresponding lower explosive limit (LEL) in on-site facility structures.
Further, the operator of the C&D landfill shall ensure that the concentration of explosive gases
does not exceed 100% of the corresponding LEL at the facility property boundary.
GAS CONTROL PLAN
HORIZONTAL EXPANSION OF THE
NASH COUNTY C&D LANDFILL
Page 2 of 3
Rule 15A NCAC 13B .0544 (d)(5) defines “lower explosive limit” as “the lowest percent by volume
of a mixture of explosive gases in air that will propagate a flame at 25°C and atmospheric
pressure”. The explosive gases typically associated with C&D landfills, and the corresponding
LEL at the stated conditions are as follows:
Explosive Gas
Lower
Explosive
Limit (LEL)
On-site
Facility
Structures
Facility
Property
Boundary
Methane 5% 25% LEL 100% LEL
Hydrogen Sulfide 4% 25% LEL 100% LEL
Field Measurement Protocol
A landfill gas monitoring unit capable of measuring methane and hydrogen sulfide concentrations
as a percent of total atmospheric gases shall be used to measure explosive gas concentrations
at each of the existing gas control probe locations and facility structures.
Corresponding values of the percent of atmospheric carbon dioxide and the percent of
atmospheric oxygen will likewise be documented. No laboratory sampling or analysis will be
conducted under this plan.
Landfill Gas Analyzer Calibration
Calibration of the landfill gas analyzer is critical to obtaining accurate sampling results.
Immediately prior to conducting field measurements, the landfill gas analyzer will be calibrated
according to the manufacturer’s recommendations in an area expected to be free of. Calibration
of the unit should be performed immediately prior to beginning routine monitoring, and in no case
greater than 12 hours before sampling.
Occupied Structures Readings
Permanent structures are constructed on a concrete slab-on-grade or elevated on a crawlspace.
Structures containing a crawlspace or otherwise open area between the structure and ground
surface will be monitored. Reading for occupied structures with a slab-on-grade will be made
inside the structures with the landfill gas analyzer’s probe as high from the floor as practical.
Readings will be recorded when the gas analyzer has reached equilibrium and the readout has
stabilized.
GAS CONTROL PLAN
HORIZONTAL EXPANSION OF THE
NASH COUNTY C&D LANDFILL
Page 3 of 3
Gas Probe Readings
The pump within the landfill gas analyzer is sized to allow the meter to rapidly purge the typical
probe casing. Readings for the existing landfill gas probes will be made by first connecting the
analyzer probe to the well casing with the shutoff valve in the open position. Positive connection
of the probe to the quick-connect attachment should be checked to see that the opportunity for
ambient air to be drawn into the analyzer is minimized. Readings will be recorded when the
analyzer has reached equilibrium and the readout has stabilized.
Reporting
Quarterly gas control monitoring results shall be submitted to NCDENR on the form attached at
the end of this Plan.
Corrective Actions
Rule 15A NCAC 13B .0544 (d)(5) specifies the corrective action requirements if methane gas
levels exceeding the limits specified in Subparagraph (d)(1) are detected.
1) Immediately take all necessary steps to ensure protection of human health and notify
the Division.
2) Within seven (7) days of detection, place in the operating record a copy of the
explosive gas levels detected and a description of the steps taken to protect human
health; and
3) Within sixty (60) days of detection, implement a remediation plan for the explosive
gas release, place a copy of the plan in the operating record, and notify the Division
that the plan has been implemented. The plan shall describe the nature and extent
of the problem, the proposed remedy.

1.0 INTRODUCTION
The North Carolina Solid Waste Rules, Section 13B .0504, specifies that the
owner/operator must provide, as part of the groundwater and surface water monitoring
program, a water quality sampling and analysis plan (SAP). The SAP is to be designed
to provide accurate assessment of groundwater and surface water quality at
upgradient/upstream and downgradient/downstream sampling locations. This SAP
addresses the following subjects.
• Groundwater and surface water sample collection
• Sample preservation and shipment
• Analytical procedures
• Chain-of-custody
• Quality assurance/quality control (QA/QC)
The methods and procedures described in the following sections are intended to
provide representative samples and test data. Field procedures are presented in their
general order of implementation. Equipment requirements are presented in each
section, and quality assurance and record keeping requirements are presented in the
last sections. Strict adherence to these procedures is required.
2.0 GROUNDWATER AND SURFACE WATER SAMPLING LOCATIONS
Groundwater and surface water will be monitored at locations as shown on Figure 1.
Well construction data for the groundwater well network is presented in Table 1. Table
1 further indicates the timing of well installation and/or abandonment relative to the
phase of landfill operation.
Groundwater and surface water samples will be collected from each monitoring point
and analyzed for a list of detection monitoring target parameters in accordance with NC
Division of Waste Management (NC DWM) regulations. Baseline detection monitoring
will consist of four independent sampling events during the initial semi-annual period,
followed by semi-annual sampling at each location thereafter.
The detection monitoring wells are designed to monitor the shallow aquifer at the site
and are constructed of 2-inch inside diameter Schedule 40 PVC, with isolated well
screen intervals, in accordance with North Carolina well construction standards 15A
NCAC 2C.
GROUNDWATER AND SURFACE WATER MONITORING PLAN
HORIZONTAL EXPANSION OF THE
NASH COUNTY C&D LANDFILL
Page 2 of 11
2.1 STATIC WATER LEVEL MEASUREMENTS
Static water levels will be measured in each monitoring well prior to purging and
sampling of groundwater. Static water level data will be used to monitor changes in
site hydrogeologic conditions. The following measurements will be recorded in a
dedicated field book prior to purging and sample collection.
• Static water level (measured to nearest 0.01 foot)
• Total depth of well
• Height of water column in well
• Changes in conditions of well, protective casing, surface pad and
surroundings
An electronic water level instrument will be used to accurately measure water levels
to within 0.01 foot. Each well will have a permanent, easily identified reference point
on the top of the PVC well casing from which all water level measurements will be
made. The reference point will be marked and the elevation of the top of the PVC
casing will surveyed by a North Carolina Registered Land Surveyor. The static
water level and total depth measurements will be used to calculate the volume of
water in the well.
The parts of the static water level instrument that will contact groundwater within the
well (e.g., graduated tape and electronic indicator) will be constructed of inert
materials such as stainless steel and Teflon™. The instrument will be thoroughly
decontaminated between well measurements by washing with non-phosphate soap
and triple rinsing with deionized water to prevent cross-contamination from one well
to another.
2.2 DETECTION OF IMMISCIBLE LIQUIDS
The detection of immiscible non-aqueous phase liquids (NAPLs) is not anticipated at
this facility based on the waste stream handled. However, the water-level
measuring instrument used at the facility (described above) will be equipped with an
electronic interface probe that is capable of distinguishing NAPLs from water.
Monitoring for both light NAPLS (less dense than water) and dense NAPLs (more
dense than water) will be conducted at the site by measuring at the water-table and
at the bottom of each well. In the event that NAPLs are detected, the instrument will
initially be cleaned with denatured laboratory grade isopropyl alcohol, followed by
washing with non-phosphate soap and triple rinsing with deionized water to prevent
cross-contamination from one well to another.
GROUNDWATER AND SURFACE WATER MONITORING PLAN
HORIZONTAL EXPANSION OF THE
NASH COUNTY C&D LANDFILL
Page 3 of 11
2.3 MONITORING WELL PURGING
Following measurement of the static water levels in all of the wells, individual wells
will be purged of all stagnant water. The stagnant water, which is not representative
of true aquifer conditions, must be removed to ensure that fresh formation water can
be sampled. Each monitoring well will be purged using a new PVC disposable
bottom-loading bailer or using pre-cleaned Teflon-lined disposable polyethylene
tubing connected to a peristaltic pump under low flow conditions.
Prior to sampling, the monitoring wells will be purged of a minimum of three static
well volumes of water, or until dry. During purging, measurements will be made in
the field of the pH, temperature, specific conductance and turbidity of the
groundwater collected from the monitoring wells, in accordance with NC DWM
requirements. Data collected will be recorded in a dedicated field book.
2.4 GROUNDWATER SAMPLE COLLECTION
After the wells are purged, groundwater samples will be collected for laboratory
analysis. New latex or nitrile disposable gloves will be donned prior to sampling at
each well. Groundwater samples will be collected using the new disposable PVC
bottom-loading bailers that were used to purge the wells or using the pre-cleaned
Teflon-lined disposable polyethylene tubing connected to a peristaltic pump under
low flow conditions. In general, sampling will be conducted as soon as practical
after purging is complete. In the event that a monitoring well runs dry during
purging, it is acceptable to allow the well to recharge up to 24 hours prior to
sampling. Similarly, wells with excess turbidity may be allowed to sit up to 24 hours
prior to sampling to allow collection of a representative groundwater sample. Water
levels in the wells will be allowed to recover for a period not exceeding 24 hours
after purging to produce an adequate sample volume. Wells that fail to produce an
adequate sample volume within 24 hours of purging will not be sampled.
Temperature, ph, specific conductance and turbidity will be measured immediately
prior to sampling as a measure of purging efficiency and the results recorded in a
dedicated field book. The temperature, pH, specific conductance and turbidity
meters will be calibrated prior to each sampling event according to the
manufacturer’s specifications and consistent with Test Methods for Evaluating Solid
Waste – Physical/Chemical Methods (SW-846).
Groundwater samples will be collected and contained in the order of volatility of
specific parameters as follows.
• Temperature, ph, specific conductance and turbidity measurements
• Volatile Organic Compounds
GROUNDWATER AND SURFACE WATER MONITORING PLAN
HORIZONTAL EXPANSION OF THE
NASH COUNTY C&D LANDFILL
Page 4 of 11
• Total Metals
All detection monitoring samples will be collected unfiltered as required by the NC
DWM.
All reusable sampling equipment, including meter probes, will be thoroughly
decontaminated between wells by washing with non-phosphate soap and water,
followed by triple rinsing with deionized water. Samples will be collected directly
from the disposable bailers or the Teflon-lined disposable polyethylene tubing
connected to the peristaltic pump into laboratory-prepared containers that have been
specifically prepared for the preservation and storage of compatible parameters. All
groundwater sample containers will be immediately placed on ice in a cooler
following sample collection in accordance with required sampling protocol.
Blanks and duplicate samples will be collected and analyzed for the same
parameters as groundwater samples to ensure cross-contamination has not
occurred. One set of trip blanks, described later in this document, will be prepared
at the laboratory and will remain in the sample cooler during sample collection and
shipment to the laboratory for analysis to ensure that the sample containers or
handling processes have not affected the quality of the samples. A duplicate
groundwater sample may be collected from a single well as a check of laboratory
accuracy and reproducibility.
2.5 SURFACE WATER SAMPLE COLLECTION
Surface water samples will be obtained from areas of minimal turbulence and
aeration. The following procedure will be implemented for sampling surface water at
each location.
• Don new latex or nitrile disposable gloves
• Hold sample bottle with one hand, and with the other, remove the cap
• Push the sample container slowly into the water column and tilt up towards
the current to fill. A depth of about 6 inches is satisfactory. Avoid breaching
the surface or agitating the water while filling the container
• If there is little current movement, the container should be moved slowly in a
lateral direction, side to side, keeping the opening pointed upstream.
Blanks and duplicates, preservatives, handling and transport procedures for the
surface water samples will be identical to those noted form the groundwater
samples.

2.6 EQUIPMENT DECONTAMINATION
All non-dedicated sampling equipment that will come into contact with groundwater
or surface water will be decontaminated before each use. The equipment
decontamination procedure is presented below.
• Clean item with tap water and non-phosphate detergent (Alconox™,
Liquinox™ or equivalent), using a brush if necessary to remove particulate
matter and surface films
• Rinse thoroughly with tap water
• Triple rinse with deionized water and allow to air dry
• Wrap with aluminum foil, if necessary, to prevent contamination of equipment
during storage or transport
2.7 FIELD QA/QC PROGRAM
Field Quality Assurance/Quality Control (QA/QC) for the subject facility requires the
routine collection and analysis of trip blanks to verify that the sampling collection and
handling process has not affected the quality of the samples. The trip blanks will be
prepared at the laboratory and transported to the site in the sample cooler with the
field sample containers, handled like a sample collected in the field, and returned to
the laboratory for analysis. The trip blanks will be analyzed for volatile organic
compounds (VOCs) only. Any VOCs found in the trip blanks will be attributed to: 1)
contaminated sample container in which the blank was prepared; 2) contaminated
source water; or 3) contamination during handling.
Any concentrations of contaminants found in the trip blanks will be reported but will
not be used to correct the water-quality data for the groundwater or surface water
samples. In the event that elevated constituent concentrations are found in the trip
blanks, the laboratory results for that constituent in the field samples will be flagged
for future evaluation and possible resampling.
3.0 SAMPLE PRESERVATION AND SHIPMENT
Sample preservation and shipment procedures will be carefully monitored to ensure
sample integrity. Ice and/or chemical ice packs will be used to preserve samples in a
cooler at the required 4°C temperature. Dry ice is not to be used. Samples will be
delivered to the laboratory via overnight courier to ensure sample holding times are not
exceeded. Shipment and receipt of the samples will be coordinated with the laboratory.
Once collected, samples will be placed on ice and cooled to a temperature of 4°C.
Samples are to be packed in high-impact polystyrene-insulated coolers so as to inhibit
GROUNDWATER AND SURFACE WATER MONITORING PLAN
HORIZONTAL EXPANSION OF THE
NASH COUNTY C&D LANDFILL

breakage of sample containers. Chain-of-custody control of all samples will be
maintained as follows.
• Labels will be placed on individual sample containers in the field, indicating
the site name, sample location, time and date of sampling, required analyses,
sampler’s initials and sample preservative.
• Sample containers will be individually secured or placed in a secure area in
iced coolers and will remain in the continuous possession of the field
samplers until custody has been transferred as provided by the chain-of-
custody form.
• Upon delivery to the laboratory, samples will be given laboratory sample
numbers and recorded into a logbook indicating client, well number, and date
and time of delivery. The laboratory manager or his designee will sign the
chain-of-custody forms and formally receive the samples. Proper refrigeration
of the samples will be maintained at the laboratory prior to preparation of the
4.0 FIELD LOGBOOK
The field samplers will maintain an up-to-date logbook and sampling forms documenting
important information pertaining to field sampling activities. The field logbook and
sampling forms will document the following.
• Site name and location
• Date and time of sampling
• Climatic conditions at the time of sampling
• Personnel conducting the sampling
• Sampling locations
• Presence of NAPLs
• Static water levels in wells
• Total depth of wells
• Purged water volumes and qualitative well yield
• Time well purged
• Observations of water samples (appearance, odor, etc.)
• Time of sample collection
GROUNDWATER AND SURFACE WATER MONITORING PLAN

• Temperature, pH, specific conductance and turbidity
5.0 LABORATORY ANALYSIS
The groundwater and surface water parameters to be analyzed will be those specified in
the landfill permit and applicable North Carolina Solid Waste Management Rules.
These will include field indicators of groundwater quality (temperature, pH, specific
conductivity and turbidity), as well as volatile organic and total metal constituents listed
in Appendix I of 40 CFR 258. All laboratory analyses will be performed by a laboratory
certified by the NC DWM for the analyzed parameters.
QA/QC procedures are to be utilized at all times. The owner/operator of the landfill is
responsible for selecting a laboratory and ensuring that they are utilizing proper QA/QC
procedures. The laboratory must have a QA/QC program based on specific routine
procedures outlined in a written laboratory QA/QC manual. The QA/QC procedures
listed in the manual provide the laboratory with the necessary assurances and
documentation for accuracy and precision of analytical determinations. Internal QC
checks shall be undertaken regularly by the laboratory to assess the precision and
accuracy of analytical procedures.
The internal QC checks include the use of calibration standards, standard references,
duplicate samples and spiked or fortified samples. Calibration standards shall be
verified against a standard reference obtained from an outside source. Calibration
curves shall be developed using at least one blank and three standards. Samples shall
be diluted if necessary to ensure that analytical measurements fall on the linear portion
of the calibration curve. Duplicate samples shall be processed at an average frequency
of 10 percent to assess the precision of testing methods, and standard references shall
be processed monthly to assess accuracy of analytical procedures. Spike or fortified
samples shall be carried through all stages of sample preparation and measurement to
validate the accuracy of the analysis.
During the course of analyses, QC data and sample data shall be reviewed by the
laboratory manager to identify questionable data and determine if the necessary QA/QC
requirements are being followed. If a portion of the laboratory work is subcontracted, it
is the responsibility of the contracted laboratory to verify that all subcontracted work is
completed by certified laboratories.
6.0 STATISTICAL EVALUATION
Copies of all laboratory results and water quality reports will be kept in the Operation
Record. Reports summarizing all water quality data and statistical evaluations will be
submitted to the NC DWM for each sampling event following the baseline monitoring
period. Methods to evaluate the data are taken from the North Carolina Solid Waste
GROUNDWATER AND SURFACE WATER MONITORING PLAN
HORIZONTAL EXPANSION OF THE
NASH COUNTY C&D LANDFILL
Page 8 of 11
Rules, 40 CFR 258.53(g) and the USEPA RCRA Ground Water Monitoring Technical
Guidance. The North Carolina Solid Waste Rules require that the owner or operator of
the landfill specify a statistical method outlined in the rules to evaluate water quality
monitoring data. The goal of the statistical analysis is to determine whether statistically
significant evidence of contamination exists and to identify the point of contamination.
Upon receipt of the data from each monitoring event, the statistical database of
analyses will be updated. The North Carolina Solid Waste Rules provide several
acceptable methods for statistical analysis of water-quality data.
• Parametric analysis of variance (ANOVA)
• Rank-based (non-parametric) ANOVA with multiple comparisons
• Tolerance prediction interval
• Control chart
• Test of proportions
• An alternative statistical method that meets the performance standards of 40
CFR 258.53(h)
Statistical evaluation of water-quality monitoring data will be performed for the duration
of the monitoring program, including the post-closure care period. The choice of an
appropriate statistical test depends on the type of monitoring, the nature of the data,
and the proportion of values in the data set that are below detection limits. The
statistical analysis will be performed separately for each detected constituent in each
well. The statistical methods used will be based on the USEPA Statistical Analysis of
Ground Water Monitoring Data at RCRA Facilities, Interim Final Guidance Document
(1989). All analyses will be performed in accordance with North Carolina Regulations
15A NCAC 13B.1632.
7.0 RECORD KEEPING AND REPORTING
7.1 NOTIFICATIONS
Should a statistically significant increase in groundwater concentrations of monitored
parameters as defined in the North Carolina Solid Waste Rules be detected during
monitoring, the owner/operator of the landfill shall notify the NC DWM within 14 days
and will place a notice in the operating record as to which constituents showed an
increase.

7.2 WELL ABANDONMENT/REHABILITATION
Should monitoring wells become irreversibly damaged or require rehabilitation, the
NC DWM shall be notified. If monitoring wells and/or piezometers are damaged
irreversibly they shall be abandoned under the direction of the NC DWM. The
abandonment will consist of plugging the well with a chemically inert sealant which is
impermeable, such as neat cement and/or bentonite clay. Where possible, it is
preferred to over-drill and remove the well casing, screen and filter pack prior to
grouting.
7.3 IMPLEMENTATION SCHEDULE
This Water Quality SAP shall become effective upon approval by the NC DWM and
will be implemented contingent on approval for construction of the landfill expansion.
Baseline sampling shall commence as soon as possible after the expansion phase is
granted approval and prior to waste being disposed each the new phase. Four
independent rounds of sampling and laboratory analyses of groundwater and
surface water shall be performed within six months of approval of the landfill
expansion. Sampling will then be performed semi-annually throughout the active life
of operational life of the facility and during the post-closure monitoring period, unless
an alternate sampling schedule is accepted by the NC DWM.
Table 1 presents timing of well installation and/or abandonment relative to the phase
of landfill operation. Proposed locations and anticipated screen intervals are shown
on Figure 1.

8.0 WELL CONSTRUCTION AND DECOMMISSIONING SPECIFICATIONS
Table 1 presents timing of well installation and/or abandonment relative to each phase
of landfill operation. The following subsections describe construction and abandonment
specifications.
8.1 CONSTRUCTION SPECIFICATIONS
The proposed Type II groundwater monitoring wells will be installed using a hollow-
stem auger drilling rig. All Type II wells will be constructed of 2-inch ID Schedule 40
PVC well casing and 10 feet of machine-slotted well screen with 0.010” slots. A
sand pack will be emplaced within the annular space to approximately 2 feet above
the top of the well screen, above which a 2-foot thick bentonite seal will be installed.
The annular space will be finished with Portland cement/bentonite slurry to grade.
The wells will be finished with solid PVC risers extending approximately 2 to 3 feet
above grade and installed in a locking steel casing with concrete pad. All
piezometers will be installed and constructed in accordance with North Carolina Well
Standards.
Soil samples will be collected at each drilling location for lithologic descriptions using
the standard penetration test (SPT) method with a 140-lb sliding hammer and steel
split-spoon samplers. Samples will be collected in 2-feet intervals for every five feet
of depth to the completion depth of the boring. The soil retained in each split-spoon
sampler will be logged by a geologist with respect to texture, composition, color, and
moisture content. In addition, one soil sample collected from the saturated zone at
each drilling location will be retained and submitted for grain size analysis at a
geotechnical laboratory to allow for estimating the specific yield of the aquifer
sediments. Additional soil index testing will be performed on select samples to
further characterize overburden soils.
The augers, drill pipe, and drill rig will be decontaminated using a pressure washer
prior to and following completion of drilling for the project. Each well will be
developed after installation using a down hole pump or bailer until the discharge
water appears to be free of suspended sediments or for a maximum of one hour.
Each well will be surveyed relative to the existing site datum for horizontal position
and elevation by a North Carolina licensed surveyor. At each well, elevations will be
measured of the ground surface and top of the solid PVC riser. A permanent mark
will be made on the top of the PVC riser at the point where the elevation
measurement is made for future reference when collecting depth to water data.

8.2 ABANDONMENT SPECIFICATIONS
Locations to be abandoned shall be over-drilled using using hollow-stem augers to
remove installed well materials. Bore holes shall be abandoned by tremie grounting,
using a cement-bentonite grout. Well materials shall be properly disposed of upon
completion.
