Re: Additional GCCS Related Services
City of Nashua Four Hills Landfill
Nashua, New Hampshire

Dear Jeff:

Sanborn, Head & Associates, Inc. (Sanborn Head) appreciates the opportunity to revise our
proposed scope of engineering services to the City of Nashua (City) relative to the Four
Hills Landfill. The scope of services presented herein is based on communication with the
City regarding additional gas collection and control system (GCCS) related services to be
completed by Sanborn Head for the City during FY 2016 and FY 2017,

Task 1 Phases | and 11 GCCS Assessment

For this task, Sanborn Head will perform an assessment of the condition and operation of
the GCCS in the closed, unlined landfill as well as Phases | and I] of the active, lined landfill.
The assessment will include the following:

e Using LFGMS, Sanborn Head will review recent wellfield data collected by the City;

= Schedule a two-day site visit to meet with City personnel to better understand current

on-site GCCS monitoring practices and procedures. As part of the site visit, we would

perform:

o A visual inspection of GCCS components (eg. wellheads/ports, boot seals,
lateral/vacuum lines, etc.);

o A landfill cover integrity assessment;

ao Gas well monitoring/data collection as necessary after initial wellfield data review;
and

o GCCS and landfill cover surface emissions monitoring at locations identified during
wellfield data review and site visit;

« Review data collected during the site visit; and

= Prepare a GCCS assessment report. The report will summarize our findings and present
our recommendations for corrective actions to improve wellfield performance.

Task 2 Dewatering System Conceptual Design

For Task 2, Sanborn Head will prepare a conceptual design and an opinion of cost for
removing liquid from LFG extraction wells in the closed, unlined landfill as well as Phases I
and II of the active, lined Jandfill. We understand that the City will be providing liquid level
measurements from the existing LFG wells for our review. We envision that the liquid
removal system will be composed of a series of submersible, air-powered pumps installed
in the wells and connected to force main pipes that discharge to leachate collection system
(LCS) risers along the perimeter of the lined landfill. Considering the number of wells
(some of which may be replaced or extended as the active Jandfill is Filled) and the potential
volume of liquid to be removed, a manifold system with quick disconnects will be designed
to provide compressed air to the pumps and connections to a drain for the pump discharge.
The design will include a dedicated pump for each well.

As part of this task, Sanborn Head will evaluate the existing air compressor located at the
Landfill Gas-to-Energy (LFGTE) facility to assess its potential in supporting the dewatering
system. The evaluation will include the air compressor and air drier (needed to limit
potential for freezing of the distribution lines), and power requirements for the electrical
equipment.

The conceptual design of the dewatering system will be presented on engineering drawings
provided electronically to the City. The engineering drawings will illustrate the air
compressor and drier layout, the manifold systems for the compressed air and liquid
discharge lines, and details that depict the pipe installation and connection details. In
addition, the design will include modifications to the LCS risers and to the well risers to
accommodate the following components: (i) LFG control wellhead; (ii) liquid removal
pump; and (iii) pneumatic liquid head monitor. The pneumatic liquid head monitor
provides a means to measure the head of liquid in the extraction well without disabling the
extraction oy pumping system. Technical specifications for materials and equipment will
be presented on the engineering drawings, and an opinion of cost based on the conceptual
design will be provided to the City.

We propose a conference call with the City as part of this task to discuss the design of the
dewatering system, opinion of cost, and steps for moving forward should the City elect to
proceed.

Task 3 GCCS Expansion in Phase li, Stage 0

Under this task, Sanborn Head will work with the City to design the next expansion to the
GCCS in Phase II, Stage II of the active landfill, We understand, based on discussions with
you, that the design is likely to include six new LFG collection trenches, one surface LFG
collection trench, and associated lateral conveyance piping and connections to the existing
GCCS. We anticipate our services to include the preparation of construction-level
drawings, technical specifications, bid item definitions, an opinion of cost for the project,
and a New Hampshire Department of Environmental Services (NHDES) Type II Permit
Modification application form with a narrative describing the proposed construction. The
drawings will be signed and sealed by a professional engineer licensed in the State of New

Hampshire. The documents will be provided to the City in Adobe Acrobat (ie, *.pdf)
format.

Task 4 Bid and Construction Phase Services

Sanborn Head understands that the City will prepare and issue bid documents for the
project. However, during the bidding process, a Sanborn Head representative will prepare
for and attend the pre-bid meeting. We understand that the City will prepare the meeting
minutes. Sanborn Head will also assist the City in addressing written questions from the
bidders.

Prior to initiating construction, a Sanborn Head representative will prepare for and attend
the pre-construction meeting. We understand that the City will prepare the meeting
minutes. During construction, Sanborn Head will provide limited observation services (i.e.,
observations limited to installation of critical components) and engineering support
services during construction of the GCCS Expansion in Phase II, Stage Il We anticipate our
services to inciude the following:

= Reviewing Contractor’s submittals and answer questions regarding design intent,
materials, and material testing;

« Observing the Contractor’s work to evaluate it for conformance with the construction
documents;

s Addressing Contractor's questions; and

=» Documenting the progress of the Contractor's work through Daily Field Reports.

Sanborn Head will provide a representative to observe and document the installation of
critical GCCS components for conformance with the drawings and technical specifications
and prepare the required field logs. In addition, Sanborn Head’s representative will
observe pipe pressure testing, HDPE pipe welds, pipe connections into the existing system,
and final well connections, performed by the Contractor.

It is our understanding that the City will observe and document the installation of the
surface collectors, and the header and lateral pipe trenching. The as-built survey of
completed features will be performed by others and will be provided to Sanborn Head in an
electronic format (i.e., dwg).

For budgeting purposes, we assunie that the construction observation will be completed
over seven (14) days, and that our representative will be on-site part time (80 hours total}

during this period, Our observations will be limited to installation of critical components.

Following the completion of the construction, and as required by the NHDES, we will
prepare a report that documents the construction work performed. The report will
address the construction activities observed, test results, and variations in construction
relative to the drawings and specifications, if any. The report also will include record
drawings, photographs, and field test data. The statements presented in the report will be
limited to the extent of our observations and our review of submittals and test results. The

report will be signed and sealed by a professional engineer licensed in the State of New
Hampshire. Paper copies and an Adobe Acrobat (i.e., *.pdf) electronic copy of the report
will be issued to the City.
