Ian Crooks, Engineering Manager from Cal Am presented an update on the Schedule of thecompletion of the boreholes reporting that the Cemex and Protrero Road bore holes returnedvery favorable results, the Moss landing area had unfavorable results for the slant test well,which revealed insufficient production potential from that area.
He spoke to the benefits and challenges for each of the testing locations. The CEMEX roadlocations is the preferred location per the settlement agreement, but he indicated that theProtrero Road location also has environmental, habitat and hydrogolocial benefits. Thechallenge is the additional pipeline needed; costs, construction complexity and no outfalldisposal option for test well. He spoke to the anticipated schedule for the test wells and theMPWSP anticipated schedule through full-scale plant start up in July of 2018.
Mr. Crooks indicated that until more progress has been made with the City of Marina, the levelof investment at Protrero Road would be minimized. He reported regarding Cal Ams effortswith the City of Marina to work with the Planning Commission and City Council prior toconsideration of the permit and spoke to the schedule for approval of permits for the MPWSP
and efforts currently underway to keep other permitting agencies informed of the project.
Chair Burnett invited comments from the public.
David Lifland questioned if the differences between the sites would affect the EIR, and if PointBlue was contacted to ensure that the Snowey Plover was not impacted. He expressedconcerns regarding Cal Ams proposed contingencies, the choice for open wells and if multipledrills can be acquired.
Mr. Crooks spoke to Mr. Liflands questions.
4. Receive Update Report, Discuss and Provide Direction Regarding Negotiations for GWRSource and Product Water, and on the Progress of the "Pure Water Monterey" Project - Israel
Mike McCullough, Monterey Regional Water Pollution Control Agency made the presentationand provided the TAC an update regarding the GWR "Pure Water Monterey" project.

He reported key activities to include: supplemental GWR budget approved onMarch 17th by the WMD, conducted outreach activities including tours, marketing speakersbureau to talk about the project benefits and updated the website. Source water discussionsare receiving negotiating concepts and discussions are ongoing.
Member Riedl requested elaborating with regard to the source water discussions asking ifprogress was being made to which Mr. McCullough indicated the teams are exchanging ideasregarding cooperating and that the negotiating teams are representing their interest withoutmuch outside agitation. Member Riedl reported about the agendized the Monterey CountyBoard of Supervisors joint meeting with Water Resource Control Agency to discuss acquiringwater rights for Blanco drain and reclamation ditch to provide potable water. The TACdiscussed the purpose of the meeting to determine the quantity and claim of water and

AGENDA ITEMS
2. Report on the Kick-Off Meeting of the Value Engineering (VE) Study Session and ReceivePublic Input on the 30% Design and on the VE Process - Cullem
Executive Director Cullem reported on attending the kick off of the Value Engineering working
group study session. He provided clarification for the purpose of the Value Engineering, whichwas not just to reduce the cost of the project, but the primary function is to improve the value ofthe project. Mr. Cullem clarified that the public is not invited to attend the VE workshop and thatthe purpose of this meeting is to accept any public comment for discussion during theworkshop. During the Directors Meeting on July 10th, a draft preliminary presentation will bemade which will accept additional comments from the public for incorporation into the finalpreliminary discussions.
Member Riley questioned if there is a risk factor related to the high cost of the slant wellinfrastructure and if the VE would address a more traditional intake system as well. ExecutiveDirector Cullem responded to the history of the evaluation of the slant wells vs. open waterintake and reiterated that settlement agreement requires the slant wells to be tested first before
the open water intake is attempted. The Coastal Commission also has a preference for slantwells.
Mr. Cullem spoke to the risk of technologies that have not been used on the west coast whichwill be addressed with the test wells and the monitoring wells. Mr. Narigi spoke to the Ceaseand Desist Order deadline, the CPUC oversight and the efforts taken to date to address hisconcerns. He further questioned how the project is being addressed with respect to the GWRproject and requested an update regarding the June 30thCPUC deadline which helps determinethe final MPWSP size. Mr. Cullem clarified that currently the MPWSP is being designed andreviewed for 9.6 MGD as a way to reduce the RO trains. He believes it has become apparentthat the project will be cheaper to design at the 9.6 at this point, and operate at a lower level.
The TAC questioned if this is the only opportunity to have the VE review the project to whichMr. Cullem responded that the contract indicates the VE review is required at a 30 percentdesign, but there is the opportunity to extend the contract for additional services at the 60percent design point. The TAC encouraged this possibility.
Member Riedl invited pubic comments on the item.
Mike Lord from Affluent Free Technology, commented on concerns expressed by TACmembers and referenced the draft ocean plan regarding desal noting California will require allurban cities to have water from desal by 2030. He expressed concern regarding the level ofbrine that would be generated, as well as factors such as intake of water, entrainment andimpingement, power usage etc. and that this project is leading the way for state legislation. He
thinks there are opportunities to find solutions and that Cal Am is prudent with their efforts toaddress the different types of wells.
Tom Rowley spoke against the projected issues of the outfall and requested the VE look atslant wells as the best source, but to keep the ratepayer in mind while making decisions.

CALIFORNIA AMERICAN WATER / RBF CONSULTING
MONTEREY PENINSULA WATER SUPPLY PROJECT HYDROGEOLOGIC INVESTIGATION
TECHNICAL MEMO RANDUM TM 1)
SUMMARY OF RESULTS - EXPLORATORY BOREHOLES
1 0
XECUTIVE SUMMARY
1 1 ntroduction
The investigation and findings described in this Technical Memorandum are the result of collaborative
planning and discussions among the hydrogeologic experts that represent key stakeholders for
groundwater use and management in the Salinas Valley and onterey Peninsula area of central
California. The Hydrogeology Working Group (HWG) consisted of the following experts: Mr. Tim Durbin
and Mr. Martin Feeney (both representing the Salinas Valley Water Coalition and the Monterey County
Farm Bureau), Mr. Peter Leffler (representing CalAm), and Dr. Dennis Williams (representing the CPUC
CEQA Team). The HWG was formed as a result of a 2013 Settlement Agreement among parties to an
ongoing CPUC-proceeding resulting from CalAm's proposed Monterey Peninsula Water Supply Project,
to review and approve the scope of field investigation and development of a hydrogeologic conceptual
model from which to construct the groundwater modeling tools. The names of the HWG members are
presented here to indicate the general agreement among the members on the core findings of the
investigative work described herein.
The work completed for this investigation was described in the Hydrogeologic Investigation Workplan
(Workplan), Attachment 1, dated 18-Dec-2013. This investigation represents the first phase of field data
gathering to develop a hydrogeologic conceptual model for the project area that is accepted by the
stakeholders. The conceptual model will be used to refine the existing North Marina Ground Water
Model (NMGWM) and construct a new focused model (CEMEX model). These models will be used to
evaluate proposed project operations and impacts. Additional phases of field testing are planned and
outlined in the Workplan.
Since September 2013, six exploratory boreholes were drilled at the CEMEX facility. Total borehole
depth ranged from 250 feet (ft) below ground surface (bgs) to 350 ft bgs. Three of the boreholes were
used to collect continuous soil cores, undisturbed soils samples, samples for mechanical grading

A significan
t clay layer is n
ot present bene
ath the Dune S

the CEMEX sit
e at
elevation
s commonly at
tributed to the S
alinas Valley A
quitard (SVA)
,suggesting a d
ifferent
depositiona
l environment t
han that of the
180-Foot Aquif
er in the Salina
s Valley. Thew
ater
quality datasuggests groundwater in the Dune Sand Aquifermay be in hydraulic continuitywith
the underlying
aquifer units
The degreeof
hydraulic con
tinuity willbe
determinedby
constructio
n of aquifer spe
cific monitorin
g wells and the
long-termpum
ping test of the
test
slant well.
Stratigrap
hic relationship
s and litholog
ic observation
s indicate that
the aquifer sys
tem
underlying th
e Dune Sand A
quifer consists
of terracedepo
sits that are old
er than the inla
nd
1
80-Foot Aquifer
deposits, since t
hey underlie the
OlderDune San
d.
The
terrace deposi
ts appear to be
a distinct lithol
ogic unit in ter
ms of geologic
history and
deposition
al environmen
t in the Dune
Highland area
and may be hy
drostratigraph
ically
equivalentto the
180-FootAquif
er in the Salinas
Valley.
For purpose
s of this docume
nt, the alluvial m
aterials encoun
tered near the co
ast (in the CEM
EX
area) are
based solely o
n analyses of bo
rehole samples
(and geophysic
al borehole logs
). As of
yet, no
direct correlatio
n can be made b
etweenthese co
astal alluvial de
positsand the s
tandard
naming
convention fou
nd furtherinlan
d (e.g., 180-Foo
t Aquifer,400-F
oot Aquifer, SV
A, etc).
C
onsequently, th
e naming conve
ntion agreed upo
n by the HWG,
includes the wo
rd equivalent
s
ince the litholo
gic units that m
ake up the aqui
fers at CEMEX
and in the Sal
inas Valley are
chro
nologically diffe
rent, but stratigr
aphically equiva
lent.
As a hydroge
ologic unit, the
terrace deposits
will be designat
ed as the 180-Fo
ot Equivalent (1
80-
FTE
) Aquifer. The
extent of h
ydrostratigraphi
c equivalencew
ill be evaluated
through a pump
ing
test utilizing
the test slant we
lls and a monito
ring network.
Th
e current interp
retation of the
distinctive dark
greenish-gray
clay found atde
pths ranging
from 241 to
282 ft bgs at C
EMEX is that i
t may represent
a change in the
depositional hi

Monterey Peninsula Water Supply Project Hydrogeologic Investigation
Technical Memorandum (TM 1) - Summary of Results - Exploratory Boreholes
.1u1 14
With the exception of the sediments penetrated in Boring PR-1 and MDW-1, individual sand and
sand and gravel lenses do not appear to be either vertically or areally extensive in Moss Landing.
Significant variations in TDS concentrations suggest that groundwater is mixed with seawater,
and is likely present in semi-isolated lenticular deposits.
In general the upper isolated aquifer test zones were above a depth of 110 ft bgs. TDS
concentrations ranged from 3,200 mg/L to 34,000 mg/L.
The lower isolated aquifer zones were generally constructed at depths exceeding 150 ft bgs.
With the exception of Zone 1 of PR-1 (190-200 feet) at 630 mg/L, the TDS concentrations ranged
from 7,400 mg/L to 34,000 mg/L.
Boring PR-1 penetrated a very permeable unit in the Perched A Aquifer from 54 to 139 ft bgs.
Groundwater in this interval approximated seawater quality (i.e., 34,000 mg/L). This unit is
interpreted to continue, but decrease in thickness southward towards Boring MDW-1. To the
north, the unit is interbedded with fine-grained units.
It is interpreted that the lowest portion of Boring PR-1 penetrated the SVA. Very low TDS
concentrations (630 mg/L) encountered in the lowest zone in Boring PR-1 suggest that isolated
zones of freshwater may exist within the 180-Foot Aquifer or that the sand unit is laterally
discontinuous and may be interbedded with the SVA. In this last interpretation, Boring PR-1 did
not completely penetrate the SVA.
Hydraulic conductivity values for the permeable portion of the Perched A Aquifer penetrated
in PR-1 ranged from 194 ft/day to 717 ft/day, based upon relationships between grain size
distribution and hydraulic conductivity.
The permeable unit between Boring PR-1 and MDW-1 represents a potential location for slant
wells.
The Moss Landing Borings (ML-1, ML-2, ML-3, ML-4, and ML-6) did not penetrate significant
thicknesses of permeable deposits to produce the required feedwater supply volume for the
MPWSP.

OTHER CONSIDER TIONS
The VE team also identified a number of observations and design comments / suggestions for
consideration primarily by the project designers. The suggestions consist of either technical review
comments on the design documents themselves or ideas for which VE team could not quantify the
performance or cost impacts. Narrative documentation of these design comments is included
following the VE Alternatives.
