acquisition (SCADA) system to automate the collection and recording of leachate
management system operating data.

The City has expressed an interest in evaluating a modification to the perimeter berm that
would honor the 500-foot setback, reduce the overall liner system construction cost, and
optimize airspace with the goal of maintaining the permitted airspace (i.e., 1.0 million yd3).
At present, the Phase III design includes a significant amount of lined area that would not
be usable for waste disposal. Recently, Sanborn Head worked with the City to modify the
vertical barrier that is required along the 500-foot setback, and one of the goals of this
project is to avoid the need to continue constructing the vertical barrier.

Lastly, as part of this project, Sanborn Head will include the following design modifications
that, in combination with other project factors, should decrease construction costs,
improve the performance of the liner and leachate collection systems, and optimize the
overall airspace:

= Modify the base liner system by:

uo eliminating the geosynthetic clay liner component of the primary liner except in the
leachate collection sump;

o replacing the single-sided geonet, geocomposite drainage materials proposed for
the base liner system with a double-side geonet, geocomposite drainage materials;
and

uo consider using tubular, geocomposite drainage materials rather than geonet,
geocomposite drainage materials to reduce or eliminate the need for leachate
collection piping;

=» Consider lowering the proposed base grades based on an evaluation of recent
groundwater and bedrock data;

= Increase the inclination of the final cover sideslopes from the permitted 3.5 horizontal
to 1 vertical (3.5H:1V) to 3H:1V;

= Increase the inclination of the liner sideslopes from permitted 4H:1V to no steeper than
2H:1V (see Env-SW 805.05(h)); and

= Incorporate a mechanically stabilized perimeter berm.
Because modifications to the permitted design are anticipated, a Type IB PMA will need to
be prepared and submitted to the NHDES for review and approval. Furthermore, to avoid

the need for a Type IA PMA, the design modifications will be such that there will not an
increase to the permitted airspace.

SCOPE OF SERVICES
Task 1 Engineering Alternatives Evaluation

Considering the City’s interest in revising the design of the perimeter berm and separation
wall, Sanborn Head will work with the City to evaluate alternative perimeter berm designs.
To kick off this task, Sanborn Head proposes having a brainstorming meeting during which
the logistical, operational, technical, and regulatory issues associated with the perimeter

berm and other potential design modifications can be discussed. Action items from the
meeting are anticipated to include preparing:

=» Aconceptual design of an alternative perimeter berm;

= Arevised liner and leachate collection system design;

= Aconceptual design of a leachate pumping and transmission system;
=» Aconceptual liner and final cover grading plan;

= Calculations of the estimated airspace volume, construction materials quantities, and a
comparison between the proposed and alternative designs;

= Calculations of slope stability, leachate collection transmissivity; and

=» An opinion of the construction costs of the permitted design versus the alternative
design.

We anticipate preparing for and attending one meeting with the City to present the
alternative design and the engineering comparison. The desired outcome of the meeting is
direction on how to proceed with the Phase II] PMA and AoT documents.

Task 2 Solid Waste Permit Modification Applications

Sanborn Head will prepare two Solid Waste PMAs (a Type IB and a Type IJ) for the City’s
signature and submittal to the NHDES. The Type IB PMA will specifically address the
design modifications accepted by the City under Task 1. The Type II PMA will provide the
construction documents. Based on our experience working with the NHDES on similar type
projects, we anticipate submitting both PMAs simultaneously.

The PMAs will include a completed form, a brief summary of the project, and references to
supporting documentation. In addition to completing the application form, we will prepare
a cover letter for the City’s use in transmitting the application to the NHDES. Also included
under this task is the reproduction of the PMAs. In accordance with current NHDES
preferences, we plan on submitting an electronic copy of each PMA so only one paper copy
of the application package will be prepared. Likewise, we will provide the City with an
electronic copy as well as one paper copy.

Prior to submitting the PMAs, we propose having a pre-submittal meeting with the NHDES.
We anticipate that this meeting would be held in Concord at the NHDES office and would
serve to assist the NHDES in their review of the documents. Our services would also
include preparing responses to the NHDES review comments to the PMAs. At this time, the
extent of review comments, if any, is not known. For purposes of this proposal, we carried
an allowance of $5,000 to respond to comments. We will notify you if it appears that the
effort to respond to comments is greater than we assumed.

For your convenience, we estimated the fees associated with submitting the PMAs. The fee
for a Type IB PMA is $100. For the Type II PMA, the fee is dependent upon the life
expectancy of the area being constructed, and was calculated using the formula provided in
Env-Sw 310.08(a) of the Solid Waste Rules. We estimate that permit application fee will be
$17,000. Please note that we assume that the City will pay the fees directly to the NHDES at

SANBORN |||) HEAD

the time the PMAs are submitted, and, as such, we did not include the fees in our budget
estimate.

Task 3 Hydrogeologic Services

According to the 1992 Solid Waste Facility Permit, as part of the final design of Phase III,
the Type II PMA is to include documentation of the elevation of the groundwater table
beneath the Phase III area. Specifically, piezometers need to be installed in the Phase III
area to evaluate the groundwater elevation with respect to the overall landfill liner system
design and the requirements of the NHDES solid waste rules. As noted in the permit, a
detailed work plan is to be prepared and submitted to NHDES for approval prior to
installing the piezometers. As part of the work plan preparation, Sanborn Head proposes
to visit the Phase III area to observe the existing topography and, if feasible, assess the
condition of groundwater monitoring wells that may be in the area. Using the information
from the site visit and the design intent for the liner system, Sanborn Head will prepare a
work plan, which will include a site map indicating the proposed piezometer locations with
respect to the proposed liner design. A draft work plan will be submitted to the City for
review and comment. Once the work plan is finalized, Sanborn Head will provide the City
with paper and pdf versions for submission to the NHDES. We anticipate addressing one
round of NHDES review comments. Once the work plan is approved by NHDES, Sanborn
Head will mark out the piezometer locations, contact DigSafe, retain a driller, supervise and
log the piezometer installation (including sampling of the soils encountered), and retain a
licensed professional land surveyor to locate the piezometers. Sanborn Head will select
representative soil samples for geotechnical laboratory testing. The information from
these activities will be summarized in a report. A draft report will be submitted to the City
for review and comment. Once the report is finalized, Sanborn Head will include it with the
Type II PMA.

Task 4 AoT Permit Application

Consistent with other land disturbing construction projects at the Four Hills Landfill, an
AoT permit application will be prepared along with the Type II PMA. Sanborn Head will
prepare the AOT permit application form and supporting documentation, including: (i) a
narrative describing the proposed stormwater management system and associated erosion
and sedimentation control features; (ii) an evaluation of the existing and proposed
hydrology; (iii) pre- and post-development runoff models and relevant design calculations
supporting the selection of proposed BMPs; and (iv) support figures illustrating the
evaluation and proposed design.

The application and supporting documents will be prepared in accordance with the
requirements of the AoT Rules (Env-Ws 1500) and will be signed and sealed by a
Professional Engineer licensed to practice in the State of New Hampshire. Our services will
also include reproducing the application and supporting information as a package to be
submitted to the NHDES. One hard copy and one electronic copy of the application will be
submitted to the NHDES, and one hard copy will be provided to the City.

SANBORN ||| HEAD

September 2, 2016 Page 5
20160902 Nashua Ph III proposal.docx

For your convenience, we estimated the AoT Permit Application fee according to the fee
schedule provided on the NHDES website, which is based upon the proposed area of
disturbance. Although the exact proposed area of disturbance is not known at this time, we
believe it will be somewhere between 400,000 and 800,000 square feet, which corresponds
to a fee of $2,750 to $4,750, the maximum fee. Please note that we assume that the City will
pay this fee directly to the NHDES at the time the application is submitted, and, as such, did
not include the fee in our budget estimate.

Task 5 Construction Documents

Sanborn Head will prepare Construction Documents that will be included with the Type II
PMA. We anticipate that the Construction Documents will include the following
components:

= General and Technical Specifications;
= Construction Drawings; and

= Construction Quality Assurance Plan.

Sanborn Head will prepare general specifications for the project (Division 1), and technical
specifications for the various components required. Typically, solid waste cell construction
projects like Phase III include Site Work (Division 2), Concrete (Division 3), Pumps
(Division 11), Mechanical (Division 15), and Electrical (Division 16).

Sanborn Head will prepare Construction Drawings for the project. The Construction
Drawings will be based upon the drawings included with the Type IB PMA.

Task 6 Project Management and Meetings

We assume that we will meet with the City three times at the site during the development
of the Phase III project. We expect that an initial meeting would be held within two weeks
of our receipt of authorization to proceed to review major design issues and establish a
project schedule. Subsequent meetings would be held to review the draft documents and
incorporate the City’s comments as the design progresses. The meetings will be
particularly useful in resolving issues regarding site access, construction sequencing,
material management, landfill gas management, stormwater management, and leachate
system design and should serve to keep the project on track from a schedule standpoint.
We expect that the meetings would involve Sanborn Head’s project staff involved in
preparation of the construction documents, and that each meeting wouid require up to 4
hours.

ASSUMPTIONS

= The City will provide recent topographic survey (i.e., 2016) of the Phase III area ina
digital format that is compatible with AutoCAD Civil 3D. The survey will be geo-
referenced to the existing site benchmarks, and references the state plane coordinate
and vertical datum used. The resulting topographic map will be produced at a scale of 1
inch equals 40 feet, with 2-foot contours.

Purchase of a 2017 Freightliner M2 Pipeline Inspection Camera Van

To approve the purchase of a 2017 Freightliner M2 106 Medium Duty Box Van
for use as the Pipeline Inspection Camera Van from Freightliner of New
Hampshire in Londonderry New Hampshire for a price of $78,544.00.
Department: 169 Wastewater; Fund: WERF - Collection Systems; Account
Classification 81 Machinery & Equipment.

Attachments: Quote and Bid Sheet

Discussion: The Wastewater Department went out to bid in September to pursue a replacement

to the current 15 year old pipeline inspection camera van. Freightliner of New
Hampshire in Londonderry New Hampshire was the sole bidder.

The current camera van #112 is a 2002 Ford E450 with 50,000 miles and has
reached the end of its life with regards to frame and structural integrity. The frame
was found to be perforated last September during the state inspection cycle, and
temporary repairs were made. Corrosion and age have made this vehicle
problematic and unreliable.

The proposed 2017 M2 106 Medium Duty Camera Van will be equipped with a 6
cylinder diesel engine, automatic transmission, heat and air conditioning and an
aluminum 20 foot box van body to house the proposed pipeline inspection camera
system and office.

The truck will carry a 2 year warranty.

The engine and aftertreatment system will have a 5 year/100,000 mile warranty.

The transmission will have a 5 year/unlimited mileage warranty.
