1.0 OVERVIEW
This Construction Documentation Report has been prepared to document the construction of an
expansion of the landfill gas (LFG) collection and control system (GCCS) located on the Phase
4A municipal solid waste (MSW) landfill unit of the Johnston County Landfill facility near
Smithfield, North Carolina. The landfill facility is owned and operated by Johnston County under
State Solid Waste Permit No. 51-03. Frontier Operation Services (Frontier) owns and operates
the landfill gas management system under agreement with the County. Original approval for
construction of the GCCS was issued by the North Carolina Division of Waste Management
(NCDWM) on February 18, 2011 (see Appendix A).
2.0 PROJECT DESCRIPTION
2.1 General

• Seven (7) LFG extraction wells (EW-201 - EW-207)
• Approximately 2,050 LF of LFG transmission piping (HDPE (DR 17)):
o 8-inch diameter: 1,550 LF; and
o 4-inch diameter: 500 LF.

3.1 LFG Extraction Wells
Prior to drilling, the location and elevation for each LFG extraction well was surveyed by
Jerry Ball Land Surveying. The survey information was verified and approved by Tent
Engineering (also reviewed by S+G) to confirm the allowable well depth'.
A total of 7 LFG extraction wells having 36-inch diameter bore and a total length and
approximate total screened length of 485 feet and 308 feet, respectively, were installed
by Kellett's Well Boring, Inc. under contract to Advance One Development, LLC (Advance
One) between June 30th and July 7th, 2020. These installations were observed by S+G
(Britt Ransom) or S&ME (Ben Best). Spoils generated from drilling operations were
inspected by an accredited asbestos inspector in accordance with the Asbestos Work
Plan. No suspect asbestos containing materials were observed during this project. Well
logs are provided in Appendix C.
Once each well was drilled, Kellett's Well Boring and Advance One performed
completion activities which were generally as follows (given dimensions are
approximate):
• 1 foot of No. 3 (non -calcareous) stone was placed in the bottom of the well bore.
• The pipe casing (6-inch diameter SCH 80 PVC) was then installed with the
perforated section ending between 20-30 feet below the ground surface and solid
pipe extending vertically to the surface.
• The well was then backfilled with additional No. 3 stone to between 18-28 feet
below the ground surface (about 2 feet above the perforated section).
• 1 foot of soil backfill was added.
• A 2 foot thick expanding foam seal was added.
• Soil backfill was added to 5 feet below ground surface.
• A 2 foot thick expanding foam seal was added.
• Soil backfill was added to the ground surface, compacted, and sloped away from
the well casing.
• Following well completion, an approximately four (4) foot section of solid casing
remained above ground as a stickup.
• Each well was fitted with a vertical wellhead assembly and connected to
transmission piping.
' The total targeted well depth was determined by taking the difference of the existing ground elevation
and the top of protective cover (from prior record drawing information) and deducting a buffer of at least
twenty (20) feet.

3.2 LFG Transmission Pioin
Advance One installed the HDPE transmission piping (including 4-inch and 8-inch
diameter HDPE (DR 17) pipe) during July 2020 and made the corresponding connections
to newly installed LFG extraction wells and the pre-existing LFG piping at various
locations. At each of two connections with pre-existing header piping a butterfly valve
was installed for control of the system.
Upon completion of the transmission piping, Advance One performed a pressure test of
the piping, which was observed by S&ME. Documentation of the pressure test is
provided in Appendix D.
Record drawings, prepared by Tent Engineering, showing the location of LFG extraction
wells and transmission piping are provided in Appendix E.
4.0 DOCUMENTATION ACTIVITIES
In satisfying the requirements of the site's approved CQA Manual, the following activities were
performed:
Observation and documentation of the installation of LFG extraction wells, system
piping, and valves.
Review of record drawing.
Preparation of this documentation report.
5.o LANDFILL GAS (LFG) COLLECTION G CONTROL SYSTEM MATERIALS

Dear Mr. Lamb:
We have completed our review of your plan for the landfill gas expansion at the subject facility
dated May 18, 2020. Based upon the information that was submitted I have a couple of comments: 1.)
Change OEE/EH Services Branch to EHS/Health Hazards Control Unit. 2.) Change the telephone number
from 919-707-5950 to my direct line 919-707-5972. 3.) If you discover asbestos at an active drill site
consider abandoning the site unless you need to drill in that exact location. 4.) Follow the OSHA signage
requirements for asbestos because there is no signage using the word "Potential".
Please adhere to the.plan as submitted to our office and keep the plan at the job site. Should there
be modifications to the plan that will impact asbestos, please inform us of the changes, in writing, before
implementing such changes.
If you have any questions, feel free to contact me at [phone].
