exploration program. The test borings will be backfilled with the drill cuttings and sand fill, if
needed.

A GZA engineer will coordinate and observe the drilling, classify soil samples, and prepare
individual logs for each exploration. The as-drilled test boring locations will be determined by GZA
using tape ties from prominent site features and/or hand-held GPS, which has a precision of +/- 10
feet.

In addition, it is noted that nearby State-listed properties included Asbestos Disposal Site (ADS)
clusters such as 49, 51, and 55 Gillis Street, which abut the Site to the south, and 55-65 Crown
Street, which abut the Site to the northeast. Historically asbestos was known to have been used as
fill in the area and based on the proximity to these listed ADSs, there is a potential that asbestos-
contaminated fill may have been used at the subject Site. Should asbestos- containing materials
(ACMs) be encountered during the proposed subsurface exploration program, drilling will be
stopped and GZA will submit a change order to properly address the encountered material,
including the development of an Asbestos Investigation Work Plan.

Test Pif Observation and Reporting - A Certified Soil Scientist (CSS) will observe the excavation of
four (4) test pits excavated in the vicinity of infiltration testing and newly installed groundwater
monitoring wells and provide profile descriptions (test pit logs} written in accordance with the
descriptive procedures, terminology and interpretations found in the Field Book for Describing and
Sampling Soils, Version 2.0, USDA, NRCS, 2002. GZA assumes one day for a CSS to complete
field observations and prepare test pit logs.

GZA will subcontract with NEBC to provide a backhoe and operator for one day for the excavation
of the test pits.

Infiltration Testing

1. GZA will contract with NEBC to install borehole casings in order to perform borehole
infiltration tests. This proposal assumes this work is performed in the same rig
mobilization/demobilization with our test borings conducted for the Park & Ride in Task 2.
We have assumed a-4-inch cased borings for the infiltration testing will be installed at four
locations at the site indicated on the attached sketch;

2. MJ will provide the depths of testing. Borehole casings will be established within the
proposed bio- retention basins or infiltration galleries. GZA assumes boring depths will not
exceed 25 feet for the purposes of this proposal;

3. GZA will perform borehole infiltration tests in accordance with the protocol stipulated in Env-
Wq 1504.14 (e)(4) to determine infiltration rates as follows:

a. Install a solid 4-inch diameter casing to a depth of 24 inches below the proposed
bottom of the BMP;

b. Remove any smeared soil surfaces and provide a natural soil interface into which
water can percolate;

c. Remove all loose material from inside the casing;

d. Fill the casing with water to a depth of 24 inches and allow to pre-soak for 24 hours;

e. After pre-soaking, refill the casing with 24 inches of water and record the drop in
water level from the top of the casing at the end of one hour;

f. Divide the drop in water elevation by one hour to obtain the infiltration rate for the
given observation;

g. Repeat e. and f., above, at least three additional times, for a minimum of four
observations in each location; and

h. Use the lower of the average of the calculated infiltration rates or the last
observation.

Laboratory Testing - GZA will conduct a geotechnical laboratory testing program including soil
gradation analyses on up to four granular soil samples recovered during subsurface explorations.
These tests will be used to confirm the field classifications of our field engineer and to estimate the
engineering properties of the soils. Testing will be performed at Thielsch Engineering's Cranston,
Rhode Island soils laboratory.

Based on apparent staining, odors, and/or PID measurements, GZA will submit up to four soil
samples and one duplicate sample to ESS Laboratories (ESS) in Cranston, Rhode Island for
analysis including: VOCs by EPA Method 8260B, polycyclic aromatic hydrocarbons (PAH) by EPA
Method 8270D, total petroleum hydrocarbon (TPH) by EPA Method 8100, and the Resource
Conservation and Recovery Act (RCRA) 8 metals by EPA Method 6010B. Soil analytical results will
be compared to the soil remediation standards (SRS} included in Env-Or 600 - Contaminated Site
Management (Env-Or 600).

Up to five groundwater samples and one duplicate sample will be submitted to ESS and analyzed
for VOCs by EPA Method 8260B, PAHs by EPA Method 8270C, and the RCRA 8 metals by EPA
Method 200.7/200.8/245.1. Groundwater data results will be compared against New Hampshire
Ambient Groundwater Quality Standards included in Env-Or 600.

Engineering Analysis and Report Preparation - GZA will conduct engineering evaluations and
develop geotechnical recommendations for design and construction of the Park and Ride. GZA
will provide a geotechnical engineering report presenting the results of the subsurface
investigations, laboratory testing, engineering evaluations, and geotechnical recommendations for
design and construction. The report will include the following, where applicable:

° Summary of subsurface explorations and laboratory testing;

° Summary and interpretation of subsurface conditions;

° Summary of infiltration rates and observed depth to seasonal high groundwater table;
° Pavement design recommendations;

° Results of test pits for seasonal high groundwater and infiltration testing;

° Results of soil and groundwater sampling and environmental laboratory testing;

. Suitability of on-site soils for reuse during construction; and

Exhibit A
Nashua - Crown Street Park & Ride Project
Scope of Work and Task Descriptions
June 15, 2016

° Construction considerations including excavation, temporary support of excavation,
dewatering, and removal of unsuitable materials.

We will prepare a geotechnical engineering report that describes the work performed, our findings,
conclusions, and recommendations. Our report will include logs of the explorations, a plan
indicating the locations of the explorations, and design details that may be necessary to
supplement the text. An electronic PDF version of the report will be provided. Boring logs will also
be provided electronically in DXF format to be included in the design plan set for the project.

Soil and Groundwater Management Plan - GZA will prepare a draft Soil Management Plan to
govern activities that may involve the disturbance of urban fill and petroleum contaminated soils at
the Site in consideration of the proposed site development, including:

° Development of a Site-Specific Health and Safety Plan;

e Development of a pian to manage the identification, stockpiling, and disposal of urban fill
and petroleum-contaminated soils;

e Segregation of soils;

e Management of stockpiled soil, asphalt, debris, and/or concrete while awaiting waste
characterization or reuse on-Site;

e Criteria for reuse and disposal of soil and any obstructions identified (i.e., foundations,
demolition debris, etc.);

e Management of water collected by dewatering during construction; and
*« Operation and maintenance of cover materials (i.e., clean fill, bituminous pavement, or
concrete).
An electronic PDF version of the report will be provided.
Task 3 — Final Design

Task 3.1 - Environmental Permitting

The project will require an Alteration of Terrain permit because it proposes over 100,000 square
feet of disturbance. MJ will prepare an Alteration of Terrain Site Specific permit application and
related plans and drainage design information for submission to NHDES. The City will be
responsible for any application fees. The site is located within a % mile of a designated river, the
Lower Merrimack River. A copy of the AoT permit will be submitted to the Local Advisory
Committee (LAC) and a representative of MJ will attend a LAC meeting if requested to do so.

It is assumed no other environmental permits will be required for this project.
Task 3.2 — Preliminary Plans, Specifications and Estimates
The Preliminary Plans will be further developed based on comments received from the City and

NHDOT. In addition to the plans developed under Task 2, the following drawings will be created.
All plans will be completed to a 95% complete level.
