© Collect an adequate number of appropriately sized juvenile herring from a location within the
Merrimack River watershed — we have assumed this can be completed in a period of four
evenings.

o PIT-tag a total of 200 juvenile herring and release directly into the power canal at Mine Falls to
evaluate downstream passage.

o Assumes installation and maintenance of a single PIT receiver during the period September-
November.

e Approach 3 - Defer

© Rely on results from the Desktop Impingement/Entrainment Survivability Assessment to

provide insight into the potential for poor turbine passage survival at the Project.

Schedule and Estimated Cost: The juvenile herring passage evaluation should occur during the fall period
(i.e., September-November) when the Project is operating under normal conditions (i.e., no unit outages, etc.).
We propose this study be conducted during the fall of 2020. Three study approaches were described above
which vary based on the monitoring approach utilized. These three approaches vary in responsiveness to the
study objectives provided by the resource agencies. The estimated costs for each level of effort as described
here is $64,571.50 (telemetry study as requested by NHFGD), $30,359.00 (reduced), and SO (propose to not
adopt field study approach until after review of desktop assessment).

Study: Adult Alosine Downstream Passage Assessment and Protection Evaluation
Requestor: NHFGD
Requestor Goal & Objectives:
e Assess the risk of adult herring and shad becoming injured, impinged or entrained in powerhouse
units.
e Estimate turbine survival.
e Estimate effectiveness of downstream fish passage.
e Assess risk of injury or mortality at the spillway and downstream bypass.
e Evaluate potential passage and protection measures.

Agency Recommended Approach:
e Evaluate turbine passage mortality for adult herring and shad using the turbines, downstream bypass
and spillway with the HI-Z balloon tag methodology.
e Conduct a downstream passage alternatives analysis of operational or structural modifications to
potentially minimize injuries/mortality relative to existing conditions.

Suggested Approach:
e Push back on conducting a HI-Z balloon tag study. Downstream passage survival for adult alosines will
be considered as part of the Desktop Impingement/Entrainment Survivability Assessment.
e Push back on conducting a downstream alternatives analysis pending review of proposed adult herring
telemetry study above.

Study: Three Dimensional CFD Modeling in Vicinity of Fishway Entrance
Requestor: NHFGD
Requestor Goal & Objectives:

AFA ASSOCIATES June 18, 2019
ENVIRONMENTAL CONSULTANTS Page 8

e Determine the flow field conditions which exist in and around the fishway entrances and create a
series of color contour maps of velocity magnitude at a range of discharges for comparison with known

fish swim capabilities.

Agency Recommended Approach:
e Collect necessary data (bed topography, water velocities, water depth) under a range of discharges

and assemble a 3-D computational fluid dynamics model.

Suggested Approach:
© Push back on conducting 3D CFD modeling of the Project fisnways unless one of the proposed passage

studies indicate a lack of safe, timely and effective passage.

Study: Downstream American Eel Passage Assessment
Requestor: NHFGD
Requestor Goal & Objectives:
¢ Quantify the movement rate and relative proportion of eels passing via the various routes at the

project.
e Evaluate instantaneous and latent mortality and injury of eels passed via each potential route.

Agency Recommended Approach:
e Evaluate the timing and route of downstream passage for adult eels at Mine Falls using radio-

telemetry.
e Evaluate turbine passage mortality for adult eels using the turbines, downstream bypass and spillway
with the HI-Z balloon tag methodology.

Suggested Approach:
® Push back on conducting a HI-Z balloon tag study. Downstream passage survival for adult eels will be

considered as part of the Desktop Impingement/Entrainment Survivability Assessment.

e Push back on additional telemetry evaluation of eels at Mine Falls until results from the Alden-DOE
bypass effectiveness study results are available. It is my understanding that eels used in that
experiment will be radio-tagged and should provide some insight into egress from the power canal.

Study: Desktop Impingement/Entrainment Survivability Assessment
Requestor: City of Nashua
Requestor Goal & Objectives:
e Provide a description of physical characteristics of the Mine Falls Project (including forebay

characteristics, intake location and dimensions, approach velocities, and rack spacing).
e Analyze target species for factors that may influence vulnerability to entrainment and mortality.
e Assess the potential for impingement and entrainment for target species.
e Estimate turbine passage survival rates.
e Estimate total project survival considering all passage routes for target species at the Project.

Suggested Approach:

e The assessment of impingement, entrainment, and survival of diadromous species will be conducted
as a desktop analysis.

e The potential for impingement or entrainment will be characterized based on the relationship of site-
specific intake characteristics along with swim speed and life history characteristics of target fish
species.

e Site-specific factors likely to influence the potential for entrainment include intake location relative to
shore and littoral habitat; depth of Project intakes; degree of water level fluctuations; hydraulic
Capacity; water quality; and intake velocities.

e Entrainment survival of juvenile and adult alosines will be estimated using data from survival studies
conducted at other hydroelectric facilities with similar characteristics [e.g., (EPRI, 1997); (Winchell,
2000)], and the Franke blade strike probability equation (Franke, 1997).

e Survival of adult eels will be estimated using the multiple linear regression models (Alden, Assessment
of Fish Entrainment, Impingement, and Turbine Survival at Holyoke Nos. 1, 2, and 3, 2017).

e Total project downstream passage survival will be characterized for adult and juvenile American shad
and alewife, and adult American eels considering the turbine passage survival estimated in this study
and any available proportional route selection data collected in the studies mentioned above.

Schedule and Estimated Cost: The desktop impingement/entrainment assessment should be conducted soon
after resource agency review of the PSP and issuance of the RSP. The estimated cost for the effort as described
here is $16,184.00.

3) Study Reports and Draft Application: Each aquatic resource study eventually agreed upon by the City
and the natural resource agencies will be conducted following the methodology summarized in the
RSP. At the completion of each study, Normandeau will prepare a summary report which provides an
overview of the goals and objectives, methodology and key results for each study. These draft reports
will be distributed to the natural resource agencies for review and Normandeau will coordinate a one-
day stakeholder meeting to review each study and address agency questions. Following review and
consideration of comments received on the draft reports, Normandeau will incorporate pertinent
comments and responses and provide a finalized set of study reports.

With regards to preparation of the Draft License Application (DLA), we have assumed that the City will
take an active role in that effort as participation will help to reduce the overall cost of the relicensing
effort. In particular, the City will take the lead on preparation of Exhibits B, C, D, G and H since staff
there have access to the detailed information required in those Exhibits. We will review and advise
the City on the content of those Exhibits to ensure that they are complete and will meet FERC
requirements and expectations. As part of the DLA effort, the Normandeau team will prepare the
Initial Statement, and Exhibits A, E, and F in accordance with FERC regulations and as stipulated in
FERC’s guidance document, Managing Hydropower Project Exhibits (FERC 2014).

A preliminary schedule of the timing of proposed studies and activities associated with the Mine Falls
relicensing process is included below in Figure 1 and was established based on an assumed contract issuance

date of August 1, 2019 and a set date for filing the Final License Application with FERC no later than two years
before the existing license expires (i.e., August 4, 2021).

Table 2 provides a summary of the total cost for the work scope as defined herein. Where multiple cost
options have been prepared for a particular field study, a line for each study option has been included in the
summary table. The tasks presented in Table 2 represent our best total cost estimate following consideration
of the existing resource agency study requests. If the scope or suite of resource studies is modified during the
course of study plan development then additional sampling not considered here will be billed on a time and
materials basis following the rates presented below in Tables 3 (Normandeau) and 4 (H.L. Turner).

It is assumed that reasonable terms and conditions can be agreed upon. For ease in expediting the award, we
have attached our standard terms and conditions for your consideration.

If you have any questions or would like to discuss the content of this letter proposal, please do not hesitate to
call Drew Trested directly at (603) 973-3179 or via an email dtrested@normandeau.com.
