3.0 SUMMARY OF CONSTRUCTION ACTIVITIES
Major elements of the project are discussed below. Photos documenting the construction of the
closure can be found in Appendix B. Prior to JRL beginning work, a project Pre-Construction
Meeting was held on February 1, 2017.

3.1 Site Preparation
Construction of the closure began in February 2017 with the surveying/staking of the
limits of construction and the initiation of site preparation activities by JRL.

3.2 Erosion and Sedimentation Control Measures
Erosion and sedimentation control measures took place in conjunction with project
activities. Permanent drainage features (down pipes, side slope swales, cap diversion
berm, perimeter channels, etc.) were added as areas were brought to grade. Once
areas reached final grade, the areas were vegetated in accordance with project
requirements.

3.3 Earthwork
Once portions of the closure area were stripped of vegetation, earthwork activities were
performed. These activities included placement of additional intermediate cover soil on
the top slopes (for additional slope and as a suitable subgrade for the overlying
geosynthetics) and placement of vegetative soil layer on the side slopes of the landfill.
Attention was given to utilized soil having a lesser quantity of gravel on top slopes
(subgrade for geosynthetics). As the side slopes were brought to grade, the soils for the
side slope swales and cap diversion berm were placed and compacted. Vegetative soil
layer was placed on top slopes after completion of the geosynthetics installation.

S+G and Geotechnics personnel verified that the thickness of the completed vegetative
soil layer was at least 24 inches by observing the thickness checks performed by JRL.

An as-built drawing showing as built vegetative soil layer (including thickness checks) is
provided in Appendix I.

3.4 Landfill Gas (LFG) Vents
As the work progressed, JRL began construction of passive LFG vents. In accordance
with the approved plans, these vents consist of perforated 6-inch diameter PVC
collection piping encased in No. 57 stone buried beneath the final cover system which is
connected to a solid 6-inch diameter PVC vent pipe. A total of 8 vents were installed.

Davidson County C&D Landfill Closure Construction Quality Assurance Report
May 2017 (Revised: June 2017) Page 5
For the 2 LFG vents installed on top slopes a booted penetration of the LLDPE
geomembrane was made.

3.5 Down Pipes
As earthwork activities progressed, JRL installed four (4) 18-inch diameter corrugated
polyethylene (CPE) (Type S) down pipes for removal of stormwater and flow in the
drainage geocomposite (via connection with the toe drain around the perimeter of top
slopes).

3.6 40 Mil LLDPE Geomembrane
Prior to the placement of geosynthetics on top slopes, a geosynthetics CQA meeting was
held on March 15th in accordance with the requirements of the project CQA manual. A
summary of this meeting can be found in Appendix C.

In accordance with project requirements, textured LLDPE geomembrane was placed
over prepared intermediate cover on top slopes. Preparation of the intermediate cover
included physical removal of visible rocks (> ½-inch in size), roots, etc. and smooth drum
rolling of the surface. NLS visually accepted the subgrade surface in advance of
material placement.

An as-built drawing showing the orientation of geomembrane panels as well as
destructive sample and repair locations is provided in Appendix I.

3.7 Drainage Geocomposite/Vegetative Soil Layer
After the 40 mil LLDPE geomembrane installation was complete, placement of drainage
geocomposite was initiated. Once the drainage geocomposite installation was
completed, the associated toe drain was installed along the inside toe of the cap
diversion berm and overlying protective cover was placed by JRL. In order to protect the
underlying geosynthetics from damage, hauling equipment operated on at least 3 feet of
material and low ground pressure dozers were used to push out the material.

The soils used for the vegetative soil layer were silty sands (SM) and silty clays (SC)
based on the test results. The material was compacted by tracked equipment during
placement as required by the project specifications.

Re: Landfill Unit Closure
Davidson County Construction and Demolition Debris Landfill (C&DLF) Unit
Davidson County, North Carolina
Permit No. 2906-CDLF-, Document ID No. (DIN) 26958

Dear Mr. Buck:

On September 29, 2016 the Division of Waste Management (DWM), Solid Waste Section
(SWS) received permit application documents (the Application) which included:
 A letter dated September 29, 2016 which formally notified the SWS that Davidson
County (the County) ceased disposal of permitted wastes in the C&DLF Unit, Solid
Waste Permit Number 2906-CDLF on June 15, 2016. You intend to close the C&DLF
Unit at the Davidson County Integrated Solid Waste Management Facility located at
220 Davidson County Landfill Road, Lexington, NC 27292.

 A project schedule for completing the proposed closure activities. To allow for potential
weather delays during the course of constructing the final cover system of the landfill, the
County requested an extension of the period for closure until May 15, 2017.

 Supporting documents for the proposed alternative final cover system including designs,
calculations, technical specifications, and the construction quality assurance (CQA) plan.
Smith Gardner Inc., on behalf of the County, prepared and submitted the above-referenced
application documents. They have been combined, scanned, and placed in the document tracking
system with a document identification number of DIN 26957.

After completing a review of the Application, the SWS determined that the proposed alternative
final cover system for the C&DLF Unit meets the requirement stated in the Solid Waste
Management Rule (Rule) 15A NCAC 13B .0543(c)(3) and can be used for the C&DLF Unit
closure project to replace the previously approved regulatory final cover system in the Closure
and Post Closure Plan dated May 2012 (DIN 16964). Additionally, the County shall conduct the
closure activities of the C&DLF Unit according to:

 Rule 15A NCAC 13B .0543, the Closure Plan (DIN 16964) except for the new final
cover system, the Application (DIN 26957) including the alternative final cover system,
the CQA Plan, and technical specifications.

 The Erosion and Sediment Control Plan approved by the NC Land Quality Section.

Pursuant to Rules 15A NCAC 13B .0542(n) and .0543(c)(4), the County shall place the letter of
intent of closure dated September 29, 2016 and the approved documents associated with the
proposed closure activities in the operating record. The County should complete the proposed
closure activities no later than May 15, 2017. Upon completion of the closure construction, the
County must submit a construction completion report according to the Closure Plan (DIN
16964), the approved Application (DIN 26957), and Rules 15A NCAC 13B .0543(c)(7) & (8). If
you have any questions or would like to schedule a meeting to discuss this matter further, please
contact me at (919) 508- 8507

Sincerely,

n-12® wt ib pipe (per AASHtO)
It’s a revolution that began nearly 15 years ago when ADS pioneered
the watertight joint for corrugated polyethylene pipe. The ADS
N-12 WT IB pipe (per AASHTO) – our third generation of watertight
joint technology – has set the standard in watertight performance.
Today’s N-12 WT IB pipe (per AASHTO) incorporates patented
technology to provide a superior watertight joint. An exterior bell
wrap provides a quick visual indicator to customers and inspectors
that a watertight product is being used. A patented gasket, that
meets all requirements of ASTM F477, increases its sealing forces
as intermittent internal or external hydrostatic pressure occurs. The
flared bell and spigot significantly improve ease of installation. N-12
WT IB pipe (per AASHTO) is so advanced in its design that it is easy to
put your confidence in for long-term reliability.
ApplicAtionS:
Storm Sewers Culverts & Cross Drains
Retention/Detention Slope/Edge Drains
Ditch Enclosures Mining/Forestry/Industrial
Roof Drainage
FeAtureS:
• 4” – 60” (100 - 1500 mm) diameters available
• Nominal 20 ft. (6m) and 13 ft. (4m) lengths available
• Integral bell and factory-installed gasket
• Joint meets or exceeds ASTM D3212 lab test as well as
ASTM F2487 and ASTM F1417 watertight field test
• Exceptional joint strength
• Excellent abrasion and corrosion resistance
• Light weight
• Structural strength that will support H-25 or HL-93 live loads with
1’ (0.3 m) minimum cover; 60” (1500 mm) pipe requires 2’ (0.6 m)
cover for H-25 or HL-93 loads
beneFitS:
• Variety of diameters and lengths fit any
project
• Pipe requires no extra couplers, grout or
other sealants for installation due to
built-in bell and factory-installed gasket.
This means fewer components to risk
performance
• Installation cost savings from lower
shipping costs, fewer people, and less
heavy equipment required.
• Hydraulic efficiency from smooth interior
• Long-term durability of HDPE

Dear Grant:

This letter is to report the final results of oven-aging and UV-aging tests (according to GRI-GM13 and
GRI-GM17) on Agru America black sheet samples that you provided to us recently. These tests were
performed by CPChem’s Materials Evaluation Laboratory in Bartlesville, OK. The tests were completed
June 2015.

The GRI-GM13 (HDPE) and GRI-GM17 (LLDPE) durability tests were done according to the following
procedures.

Test Exposure Method
HP-OIT 150 °C, 500 psi oxygen D5885
Oven Aging 90 days, 85 °C D5721
UV Aging 1600 UV hrs (Conditions were 20 hours UVA-340 at 75 °C followed by 4 hrs
dark with condensation at 60 °C. Irradiance was 0.72 W/m2 at 340 nm.)

Limited Material Warranty

OWNER: Davidson County
REQUESTED BY: National Lining Systems, Inc.
PROJECT: Davidson County C&D Landfill Closure
TYPE MATERIAL: 40 mil LLDPE Double-sided Microspike® Liner
LOCATION: Lexington, NC
EFFECTIVE DATE: 3/13/17

AGRU AMERICA, Inc. (AGRU) warrants its material for a period of FIVE(5) Years, prorated, from the final
project ship date when subsequently properly installed, covered and used for a LANDFILL CAP (BURIED).
AGRU warrants that the liner will be free from material defects and is manufactured in all material
respects to AGRU’s product specifications as indicated in the applicable AGRU technical records,
catalogs, guidelines, and test certificates in effect at the time when the liner is sold. Note: AGRU’s
products may vary in details of design and construction from descriptions in any literature or from any
sample, display, or other model inspected by Customer.
AGRU disclaims all other representations and warranties of any kind, express or implied, in fact or in
law, including, without limitation, the implied warranty of merchantability and the implied warranty of
fitness for a particular purpose. Every claim under this limited warranty shall be deemed waived unless
in writing and received by SELLER within 14 days of delivery if visibly damaged or defective, and,
otherwise, within 30 days after the defect to which each claim relates is discovered, or should have been
discovered, but in no event longer than FIVE (5) Years after installation.
AGRU’s liability under this limited warranty is not applicable when damage is caused by: Natural
phenomena such as, but not limited to: thunderstorms, floods, earthquakes, or other acts of God; and
acts of war, machinery, foreign objects or animals; and Chemicals which are not suitable for LLDPE liner
materials.
AGRU’s Limited Material Warranty will be void if any of the material is shipped prior to completion and
approval of all testing required by the project specifications.
Further, the AGRU limited warranty is voided by, and AGRU in no event shall be liable for damages due
to improper site preparation, as well as the misapplication, incorrect installation (including incorrect
welding of seams in the installation), and/or damages resulting from any kind of improper handling.
Further, AGRU’s warranty will be void in the event that the Customer performs repairs or makes
alterations without the express approval of AGRU in writing. Customer shall not repair, replace,
remove, alter, or disturb any liner prior to AGRU’S inspection except that the Customer may take
emergency action necessary to prevent damage to persons, property or the environment. Failure to
comply with this paragraph shall void the warranty.

This warranty is only valid on condition that the generally approved technical standards, and in
particular the guidelines for the installation of the liner, are followed in all respects.
AGRU shall be given an opportunity to ascertain the cause of damages. AGRU reserves the right to
decide how damages will be settled. Customer agrees that it shall provide AGRU with clean, dry and
unobstructed access to the liner in order for AGRU to perform the inspections and repairs which may be
required pursuant to the warranty. AGRU shall not be obligated to perform any inspection or be
obligated to perform any repair or replacement under this warranty until the area is made available free
from all obstructions, water, dirt, sludge, residuals and liquids of any kind. AGRU shall not be liable for
any costs relating to providing such access to the liner. If after inspection it is determined that there is
no claim under this warranty, Customer shall reimburse AGRU for its costs associated with the site
inspection.
Customer’s exclusive remedy and the limit of AGRU’s liability for breach of this limited warranty,
whether based on negligence, breach of warranty, strict liability, or any other theory, at law or in equity,
shall be, at AGRU’s option: repair, replacement with a like quantity of non-defective product, or refund
of the purchase price, plus reasonable handling and transportation charges incurred for approved
refunds.
AGRU will not be held responsible for any delays in performing approved material repairs or
replacements that are caused by machinery or mechanical failure beyond AGRU’s control.
AGRU’s maximum liability under this warranty will not exceed the purchase price of liner and will only
be in force when payment has been made in full, and further claims, regardless of the legal suppositions,
are not applicable.
All AGRU products (including liners) are sold under AGRU’s General Terms and Conditions, including this
Limited Material Warranty, and bar on recovery of consequential and other damages.
AGRU AMERICA SHALL NOT BE LIABLE FOR ANY CONSEQUENTIAL OR SPECIAL DAMAGES BASED ON
NEGLIGENCE, BREACH OF WARRANTY, STRICT LIABILITY, OR ANY OTHER THEORY, FOR FAILURE TO
PERFORM ITS OBLIGATIONS UNDER THIS AGREEMENT. ADDITIONALLY, CONSEQUENTIAL AND SPECIAL
DAMAGES SHALL NOT BE RECOVERABLE EVEN IF THE REPAIR, REPLACEMENT, OR REFUND REMEDY FOR
AGRU AMERICA’S BREACH OF ITS LIMITED WARRANTY FAILS ITS ESSENTIAL PURPOSE OR FOR ANY
OTHER REASON.
No warranty made by any representative of AGRU, or any other person, regarding the AGRU material
shall be binding upon AGRU except the warranty set forth herein.
