RE: Request for Additional Information
Construction Plan Approval
Gas Collection and Combustion System
Francis Farm Landfill
Haywood County, North Carolina
Permit # 44-03
Dear Mr. Gaither:
We appreciate your review of the submittal pertaining to the construction of a gas
collection and combustion system at the Francis Farm Landfill in Haywood County. The
following is our response to your review letter, dated January 27, 2010.
1. A" technical discussion of the construction practices for drilling, excavation, backfilling
material and fabrication, waste disposal, control of nuisance odors, vectors and windblown
material, personnel safety, decontamination of tools and machinery, testing protocols and
frequencies, etc.
Well Construction Methods
Proposed wells were laid out to provide a radius of influence of approximately 105 feet.
Twenty-one new well locations were identified. The well locations will be staked out and the
ground elevation at the well recorded. There is only limited information pertaining to the bottom
grades of the landfill, and these base elevations have not been verified. Haywood County will
install their methane extraction wells such that the bottom of the well is 5-10 feet above the
bottom elevation of the landfill. As noted on the plans, it is anticipated that 4-5 wells may be
extended into the soil beneath the bottom of the landfill in order to determine the bottom
elevation of the landfill. The depth to bottom of the landfill will be recorded. These wells will
then be immediately backfilled with a clay/bentonite mixture to an elevation 5 feet above the
bottom of the landfill. The landfill bottom elevation information will be utilized to estimate the

depth of the remaining wells. See the well construction details on Sheet C-502 of the plans for
the requirements of the well installation, including the materials used for backfilling the wells.
The County will hire a company experienced in landfill gas extraction well installation to
install the wells and well piping. A bucket auger or rotary auger/drill installation will be utilized.
See Specification Section 02440 pertaining to landfill gas extraction well installation for
additional information relating to the extraction well construction.
Prior to beginning any well installation activities, the contractor will be required to
submit their Safety Manual and Standard Operating Procedure Manual, as it pertains to the
construction of landfill gas extraction wells, for review and approval. At a minimum, a
protective cover/screen shall be placed over the excavated well any time the boring operation is
not underway to ensure that personnel do not enter the well. Under no circumstances shall an
open borehole be left unattended. All boreholes shall be completed and backfilled prior to the
end of each day's work.
The contractor will be required to use whatever means or methods are necessary to
prevent contamination of the surrounding landfill surface with refuse tailings removed from the
borehole. Any contamination shall be immediately removed and the landfill surface, restored to
its original condition. Additionally, Haywood County will provide the institutional controls
necessary to ensure that the contractor maintains the environmental integrity of each work site as
well as the integrity of the landfill cap system as a whole..
The Haywood County Landfill Manager, Denese Ballew, or landfill staff under her
supervision, will be at the site during the drilling to ensure that the well driller installs the wells
as shown on the plans and to determine landfill bottom depths. The County staff will also ensure
that any damage done to the landfill cap system, as a part of this project, is promptly repaired to
its original condition (i.e., contours, cap thickness, drainage berms, etc.).
Wastes removed during the drilling will be buried at the top of the landfill, as shown on
Sheet C-101 of the plans, and covered in accordance with the detail on Sheet C-501 of the plans.
In order to control odors, vectors, and wind-blown material, all wastes shall be covered as soon
as possible after placing at the top of the landfill in the location designated on the plans. At a
minimum, all wastes shall be covered at the end of the day's work. Additionally, drilling
equipment shall be cleaned of all loose debris and/or waste material prior to relocating the
equipment to a new drilling location or staging area. The materials removed from the drill rig
shall be contained and buried in the same area as the refuse tailings from the borehole.
It is not clear at this point regarding the amount of water in the waste mass or the extent
of dewatering appurtenances that may be required. The County will monitor water elevations
within the waste mass after the installation of the extraction wells prior to proceeding with the
dewatering appurtenances shown on the plans.

Piping will be installed by a Contractor experienced in utility construction. Testing of
installed pipes will be to industry standards, utilizing air testing or water testing, at the discretion
of the Contractor. Pipe trenches will be constructed as shown on Sheet C-501 of the plans. Any
wastes uncovered during piping installation will be removed and disposed of as noted above.
The methane flare station will be purchased from a company experienced in flare station
fabrication and the system will installed by a Contractor experienced in methane flare
installations. The flare and appurtenances will be installed as shown on Sheets C-101, C-503,
and C-504 of the plans. The flare supplier will be on site during the installation of the flare
systern to ensure that the flare is installed properly. The supplier will also be responsible for
initial flare startup and training County employees in the operation of the flare system.
One hard copy and one digital copy of the following information is enclosed along with a
digital copy of the letter:
*Specification Section 02410 — HDPE Methane Condensate Sump
*Specification Section 02420 — Landfill Gas Collection Piping
*Specification Section 02430 — Landfill Gas Header Isolation Valves
•Specification Section 02440 — Landfill Gas Extraction Wells
*Specification Section 02450 — Landfill Gas Wellheads
*Specification Section 02460 — Leachate Well Pumps
Once construction is complete, a completion report will be prepared and submitted to the
Department for review and approval. The report will include, at a minimum, the information
requested in your review letter dated January 27, 2010.
We look forward to obtaining an authorization to construct for this project. Please do not
hesitate to contact us if you have any further questions regarding this submittal or if you require
additional information.
Sincerely,
