RECOMMENDED ACTION:
THAT THE CITY OF CARLSBAD CITY COUNCIL: Adopt Resolution No. dm-37 for
Approval of a Mitigated Negative Declaration for the Encina Basin Water Reclamation
Program, Phase II Project, Case No. EIA 99-09; CMWD Project No. 98-301.
THAT THE CARLSBAD MUNICIPAL WATER DISTRICT BOARD OF DIRECTORS: Adopt
Resolution No. 1072 for approval of a Local Resources Program (LRP) Agreement
between Metropolitan Water District of Southern California (MWD), San Diego County Water
Authority (SDCWA), and Carlsbad Municipal Water District (CMWD) for Encina Basin Water
Reclamation Program, Phase I and Phase II Projects; CMWD Project No. 98-301.
ITEM EXPLANATION:
In March, 1992, the City Council adopted the “City of Carlsbad Water Reclamation Master
Plan”. The master plan envisioned delivering up to 11,480 acre-feet per year (AF/YR) of
recycled water to City-wide, based on meeting existing and projected irrigation demands
and industrial uses for the water. The master plan recommended the development of the
recycled water system in five phases referred to as the Encina Basin Water Reclamation
Program, or the “program”. Phase I of the program was initiated in 1992, completed in
1994, and has a capacity of 2050 AF/YR. Funding for Phase I of the program was obtained
from two sources: the State Water Resources Control Board and the MWD through their
Local Projects Program, which was converted to MWD’s Local Resources Program (LRP) by
agreement dated July 1, 1999.
In 1997, CMWD updated the program. Phase II of the updated program will increase
capacity by 2,950 AF/YR. Phase II includes the following components:
l Construction of a new 5.0 mgd advanced tertiary water reclamation plant referred to as
the Carlsbad Water Recycling Facility (CWRF).
l Construction of approximately 10 miles of pipelines ranging in size from 4 to 24 inches in
diameter.
l Construction of three pumping stations.
l Construction of improvements to the existing 54 MG Mahr Reservoir.
l Conversion of two existing reservoirs from potable water storage to recycled water
storage.
l Construction of up to three 10 MG secondary flow equalization basins to equalize flow to
the CWRF and for the Encina Water Pollution Control Facility’s oceanoutfall.

Conventional project processing usually involves, although does not require, concurrent
consideration and actions regarding a project’s environmental determination and
entitlement. Additionally, often project processing will involve some degree of consideration
by the Planning Commission. For this City project, however, the environmental review
process has been conducted, and a recommended environmental determination has been
made, in advance of the project’s detailed review and entitlement. Additionally, the project
has been brought directly to the City Council. The reason for this relates to the CMWD’s
need to secure participation in a MWD rebate program, which requires an executed
agreement and environmental determination for the project early this year.
Detailed project review, of Phase II will commence in February 2000. Phase II project
entitlement will follow and occur at future public hearings before both the Planning
Commission and City Council, which are expected to occur in the spring and summer of this
year. Project entitlement will include a General Plan Amendment, a zone change, a Local
Coastal Program Amendment, a Precise Development Plan Amendment, a Coastal
Development Permit, and a Conditional Use Permit.
Based on the Environmental Impact Assessment for the Phase II project, a Mitigated
Negative Declaration was issued by the City on December 10, 1999. Comments from the
public were invited to be submitted to the Planning Department within 30 days of the date of
issuance. Correspondence which has been received, as of the date of this report
preparation, have been included as an attachment to this report. Staff will deliver a verbal
repot-tin response to submitted comments at the City Council meeting.
In September, 1998, the CMWD submitted a Phase II project proposal to MWD to obtain
funding from their Local Resources Program (LRP). The Phase II project was competitively
evaluated by a review committee and subsequently identified as one of 14 projects
recommended for inclusion in the LRP. A draft agreement has been prepared to obtain an
LRP contribution from MWD that will vary from $210/AF in 2001 to $lOO/AF beginning in
2010 and terminating in 2019. In addition, the draft agreement calls for combining the
Phase I and Phase II projects to obtain the same contribution for each project. This avoids
maintaining separate accounting records on each project. The agreement between MWD, the
SDCWA, and CMWD must be authorized and executed by all agencies by April 1, 2000.
Two separate actions are required by the City Council at this time for the Phase II project.
The first is to approve the Mitigated Negative Declaration for the Project issued on December
10, 1999 by the Planning Department for the City of Carlsbad. The second action is to
approve an agreement with CMWD, MWD, and the SDCWA to obtain funding from MWD’s
Local Resources Program.
FISCALIMPACT:
In accordance with the LRP Agreement, CMWD will receive a contribution from MWD. This
amount will vary on an annual basis from $210/AF to $lOO/AF for every acre-foot of
recycled water sold through fiscal year 2018-2019. The total potential contribution is
$11,818,000. The LRP Agreement has two performance provisions. The LRP Agreement will
terminate if construction of Phase II facilities has not commenced by April 01, 2002. The
LRP Agreement will terminate if Project production is not delivered from the proposed 5mgd
CWRF by April 01, 2004. If the LRP Agreement terminates the existing Phase I Recycled
Water Project and the existing LRP Agreement will not be superseded by the new LRP
Agreement.

ENVIRONMENTALREVIEW:
A Mitigated Negative Declaration and Mitigation Monitoring and Reporting Program have
been prepared for the Phase II project. The Environmental Impact Assessment (EIA) Part
II for the project concluded that the project would result in potentially significant effects on
the environment in the following areas: land use and planning, biological resources,
hazards, aesthetics, and cultural resources. Each of these potentially significant impacts,
however, can be mitigated to a level of insignificance, with mitigation measures. The
mitigation measures are incorporated into the Mitigation Monitoring and Reporting Program
which is included as an attachment to the Resolution included with this report, Revisions in
the project p’lans or proposals made, or agreed to, by the applicant before the proposed
Mitigated Negative Declaration and Initial Study are released for public review would avoid
the effects or mitigate the effects to a point where clearly no significant effects would
occur.

The City of Carlsbad has conducted ati environmental review of the above described project pursuant to
the Guidelines for Implementation of the California Environmental Quality Act and the Environmental
Protection Ordinance of the City of Carlsbad. As a result of said review, the initial study (EIA Part 2)
identified potentially significant effects on the environment, but (I) revisions in the project plans or
proposals made by, or agreed to by, the applicant before the proposed negative declaration and initial
study are released for public review would avoid the effects or mitigate the effects to a point where
clearly no significant effect on the environment would occur, and (2) there is no substantial evidence in
light of the whole record before the City that the project “as revised” may have a significant effect on the
environment. Therefore. a Mitigated Negative Declaration is hereby issued for the subject project.
Justification for this action is on file in the Planning Department.
A copy of the Mitigated Negative Decl&ion with supportive documents is on file in the Planning
Depament, 2075 Las Paimas Drive, Carlsbad, California 92009. Comments from the public are invited. Please submit comments in writing to the Planning Department within 30 days of date of issuance. If

5. PROJECT DESCRIPTION:
In 1992 the Carlsbad City Council adopted the City of Carl&ad Reclaimed Water Master Plan, which consists
of 5 implementation phases, Phase I was evaluated under previously prepared and certified environmental
documents, has been constructed, and began full operation in 1994. Phase I generally involved establishment
of components of the Meadowlark and Gamer water recycling facilities; conversion of two, existing reservoirs
from potable water to recycled water storage; construction of a pumping station; and installation of transmission
pipelines. Phase II, referred to as the Encina Basin Water Reclamation Program Phase II, is an integral
expansion of the existing Phase I facilities and involves the following major components:
l Construction of a new advanced tertiary water recycling plant, the Carl&ad Water Recycling Facility
(CWRF). with a capacity of 5 million gallons/day (MGD) on the vacant site adjacent to, and south of, the
existing Encina Water Treatment Plant The project/site layout has been designed to accommodate an
expansion to 16 MGD, but it is not a part of this project.
l Construction of three (3) booster pumping stations located: in the southeast section of the Calavera Hills
community, near Lake Calavera; at the existing “Twin D” water tank site near the intersection of Poinsettia
Lane and Black Rail Road; and on the east side of El Camino Real just south of the Palomar Airport Road
intersection.
l Upgrades and other site improvements to the existing Mahr Reservoir facility.
l Installation of minor improvements at the existing Encina Water Treatment Plant which are associated with
the water recycling program.
l Installation of a combined total of approximately 10 miles of new recycled water transmission pipelines at
vanous locations throughout the City. .
Proceedurally and in order to obtain full entitlement. the project requires the following discretionary actions: a General Plan (GP) amendment, a Local Coastal Plan (LCP) amendment, a zone change, a
Precise Development Plan (PDP) amendment, a Coastal Development Permit (CDP), and a Conditional Use Permit (CUP). The Carlsbad Planning Commission will be reviewing the project and making a
recommendation to the Carlsbad Ciy Council. California Coastal Commission (CCC) review will be
re+ured for the LCP amendment. These discretionary actions/project entitlements are scheduled to occur
in the spring and summer of the year 2000. At this time, however, CMWD is interested in securing
parncipation in a Metropolitan Water District (MWD) rebate program, which requires an executed

agreement and completed environmental analysis on Phase II in early Year 2000. Therefore, the
environmental analysis has been completed in advance of the various discretionary actions/project
entitlements. A more detailed project description is included in the Discussion of Environmental
Evaluation section.

DETERMINATION.
(To be completed by the Lead Agency)
I find that the proposed project COULD NOT have a significant effect on the environment, and a
NEGATIVE DECLARATION will be prepared.
I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because the mitigation measures described on an
attached sheet have been added to the project. A MITIGATED NEGATIVE DECLARATION
will be prepared.
I find that the proposed project MAY have a significant effect on the environment, and an
ENVIRONMENTAL IMPACT REPORT is required.
I find that the proposed project MAY have significant effect(s) on the environment, but at least
one potentially significant effect 1) has been adequately analyzed in an earlier document pursuant
to applicable legal standards, and 2) has been addressed by mitigation measures based on the
earlier analysis as described on attached sheets. An EWNeg Dee is required, but it must analyze
only the effects that remain to be addressed.
I find that although the proposed project could have a significant effect on the environment, there
WILL NOT be a significant effect in this case because all potentially significant effects (a) have
been analyzed adequately in an earlier Master Environmental Impact Review (MEIR 93-01)
pursuant to applicable standards and (h) have been voided or mitigated pursuant to that earlier
Master Environmental Review (MEIR 93-01) including revisions or mitigation measures that are
imposed upon the proposed project. Therefore, a Notice of Prior Compliance has been prepared.

STATE CEQA GUIDELINES, Chapter 3, Article 5, Section 15063 requires that the City conduct an
Environmental Impact Assessment to determine if a project may have. a significant effect on the
environment. The Environmental Impact Assessment appears in the following pages in the form of a
checklist. This checklist identifies any physical, biological and human factors that might be impacted by
the proposed project and provides the City with information to use as the basis for deciding whether to
prepare an Environmental Impact Report (EIR), Negative Declaration, or to rely on a previously
approved EIR or Negative Declaration.
l A brief explanation is required for all answers except ‘Wo Impact” answers that are adequately., .
supported by an information source cited in the parentheses following each question. A “No
Impact” answer is adequately supported if the referenced information sources show. that the
impact simply does not apply to projects like the one involved. A “‘No Impact” answer should be
explained when there is no source document to refer to, or it is based on project-specific factors
as well as general standards.
l “Less Than Significant Impact” applies where there is supporting evidence that the potential
impact is not adversely significant, and the impact does not exceed adopted general standards and
policies. .
l “Potentially Significant Unless Mitigation Incorporated” applies where the incorporation of
mitigation measures has reduced an effect from “Potentially Significant Impact” to a “Less Than
Significant Impact.*’ The developer must agree to the mitigation, and the City must describe the
mitigation measures, and briefly explain how they reduce the effect to a less than significant
level.
0 “Potentially Significant Impact” is appropriate if there is substantial evidence that an effect is
significant.
l Based on an “E&Part II”, if a proposed project could have a potentially significant effect on the
environment, but fl potentially significant effects (a) have been analyzed adequately in an earlier
EIR or Mitigated Negative Declaration pursuant to applicable standards and (b) have been
avoided or mitigated pursuant to that earlier EIR or Mitigated Negative Declaration, including
revisions or mitigation measures that are imposed upon the proposed project, and none of the
circumstances requiring a supplement to or supplemental EIR are present and all the mitigation
measures required by the prior environmental document have been incorporated into this project,
then no additional environmental document is required (Prior Compliance).
l When “Potentially Significant Impact” is checked the project is not necessarily required to
prepare an EIR if the significant effect has been analyzed adequately in an earlier EIR pursuant to
applicable standards and the effect will be mitigated, or a “Statement of Overriding
Considerations” has been made pursuant to that earlier HR.
l A Negative Declaration may be prepared if the City perceives no substantial evidence that the project or any of its aspects may cause a significant effect on the environment.
4 ” Rev. 03128 96
l If there are one or more potentially significant effects, the City may avoid preparing an EIR if
there are mitigation measures to clearly reduce impacts to less than significant, and those
mitigation measures are agreed to by the developer prior to public review. In this case, the
appropriate “Potentially Significant Impact Unless Mitigation Incorporated” may be checked and
a Mitigated Negative Declaration may be prepared.
l An EIR must be prepared if “‘Potentially Significant Impact” is checked, and including but not
limited to the following circumstances: (1) .the potentially significant effect has not been
discussed or mitigated in an Earlier EIR pursuant to applicable standards, and the developer does
not agree to mitigation measures that reduce the impact to less than significant; (2) a “Statement
of Overriding Considerations*’ for the significant impact has not been made pursuant to an earlier
EIR; (3) proposed mitigation measures do not reduce the impact to less than significant, or; (4)
through the EIA-Part II analysis it is not possible to determine the level of significance for a
potentially adverse effect, or determine the effectiveness of a mitigation measure in reducing a
potentially significant effect to below a level of significance.
A discussion of potential impacts and the proposed mitigation measures appears at the end of the form
under DISCUSSION OF ENVIRONMENTAL EVALUATION. Particular attention should be given to
discussing mitigation for impacts which would otherwise be determined significant.

DISCUSSION OF ENVIRONMENTAL EVALUATION
I. BACKGROUND AND PROJECT DESCRIPTION
The Carlsbad Municipal Water District (CMWD) is planning an expansion to the City’s existing
reclaimed, or recycled, water program which is entitled the “En&a Basin Water Reclamation Program ,
Phase II”. An overview of the various institutional arrangements affecting the project, a background of
the planning process, and a description of Phase I has been included for background. A detailed project
description of Phase II, including an summary of technical processes as well as physical project
components, is provided later in this section
Institutional Overview
CMWD is a subsidiary agency of the City of Carlsbad, and the City Council of Carlsbad serves as its
Board of Directors. CMWD provides all planning, construction, operation and maintenance of the
recycled water program. CMWD provides potable water, recycled water, and sewer services within the
City of Carlsbad. Each of these services has a separate service area boundary, and they are not
contiguous. The recycled water service area includes the City limits of Carlsbad consisting of
approximately 24,788 acres (38.73 square miles) as shown on Figure 1 Within CMWD, potable water is
supplied exclusively through an imported water supply because local ground and surface water is,, of a
roor quality’ (i.e. high salt content) and inadequate to meet current demands. The CMWD receives imported water via aqueducts operated by the Metropolitan Water District (MWD) and the San Diego
County Water Authority. The imported water consists of a blend of Colorado River Water and State
Project Water. Before delivery to CMWD, the imported water is treated at MWD’s Skinner Filtration
Plant located near the City of Temecula, in Riverside County.
Wastewater treatment within Carlsbad is handled at three separate treatment facilities. The largest treatment facility. having a capacity of 36 million gallons per day (mgd), is the Encina Water Pollution Control Facility
(EWPCF), which is owned and operated by the Encina Wastewater Authority - a joint powers agency of which
the City of Carlsbad is a member. The second largest w&tewater treatment facility is the Meadowlark Water
Reclamation Plant (MWRP) having a capacity of 2.0 mgd, which is owned and operated by the Vallecitos
Water District. The third treatment facility is the Gamer Water Reclamation Plant having a capacity of 0.75
mgd and owned and operated by the Leucadia County Water District (LCWD). In 1999, LCWD ceased
operation of the wastewater treatment portion of the plant and now pumps secondary treated eftluent from the
EWPCF to the filters at the Gamer Water Reclamation Plant to produce tertiary treated effluent (recycled
water).
CMWD’s groundwater and surface water quality, wastewater management, and water recycled activities are
under the regulatory Jurisdiction of the California Regional Water Quality Control Board (RWQCB), San
Diego Region. Administration of water recycling activities was delegated to CMWD by the RWQCB through
“Order’ No. 98-200 Master Reclamation Permit for Carlsbad Municipal Water District, San Diego County”
adopted on December 16, 1998. This order allows CMWD to deliver recycled water to all areas in the City of
Carlsbad.
Planning Background
On May 8. 1990. the Board of Directors of CMWD adopted Ordinance No. 3 1, mandating the use of recycled
water wherever feasible in the Dismct. CMWD began planning the recycled water system culminating in the
development of a report titled “City of Carlsbad Water Reclamation Master Plan” adopted by the City Council
in March. 1992. The master plan was separated into five phases and envisioned delivering up to 11,480 acre-
feet per year with a peak.,demand of 21.4 mgd of recycled water to the entire City based on existing and
projected irrigation demands.
The Phase I project, was initiated in 1992 and completed in 1994. It was funded through a low interest loan
horn the State Water Resources Control Board, and a rebate program from MWD and the San Diego County
.
Water Authority. Funding from MWD was obtained through their Local Projects Program, which CMWD
later converted to MWD’s Local Resources Program (LRP).
Current Planning
* As noted previously, the Reclaimed Water Master Plan separated the development of the recycled water system
into five phases for implementation. Phase I was completed and began full operation in 1994. By 1997, the
demand for recycled water began to exceed the available supply. To make more efficient use of available local
water resources the CMWD proposes to construct Phase II of its recycled water program. To accomplish this,
in 1996, CMWD began updating the Reclaimed Water Master Plan and completed this effort in 1997. A report
was prepared titled “Update of the Reclaimed Water Master Plan”. This report identified ten possible
alternatives for the Phase II project after investigating customer irrigation demands, determining options for
increasing the treated supply, locating pipelines, pumping stations, and reservoirs, and reviewing funding
alternatives. Alternative 9 was recommended for Phase II increasing the recycled water supply from 2.75 mgd
to 8.00 mgd with an average annual demand of 4,480 acre-feet per year or 4.00 mgd.
-In September 1998, CMSVD submitted a proposal to MWD’s LRP to obtain funding for a portion of the Phase
II recycled water system’s operation and maintenance costs. In January, 1999, MWD submitted a written
response indicating a willingness to approve funding.
for this projfct.
CMWD is currently negotiating a contract with MWD
CMWD also is preparing an application to SWRCB’s Revolving Fund program to obtain a
portion of the Phase II Reclaimed Water Project’s capital tiding through a low interest loan. The application
_ will address facilities required for Phase II. . . .
CMWD in a cooperative effort with Leucadia County Water District, Olivenhain Municipal Water District, and
San Elijo Joint Powers Authority, also applied for Public Law 102-575 Title XVI funding through the Federal
Bureau of Reclamation. The Phase II project was combined with projects proposed by the other agencies on
the application and contained under the funding title “North San Diego County Area Water Recycling Project”.
Under the Reclamation, Recycling and Water Conservation Act of 1996, the Bureau of Reclamation was
authorized to participate in the North San Diego County Area Water Recycling Project at a federal cost-share of
up to 25 percent. However, no appropriation has been approved.
Existing Phase I Recycled Water Facilities
As indicated, CMWD has completed the Phase I of the project. This system can supply up to 2.75 mgd of
recycled water. The facilities for Phase I consist of the following:
Supply Sources- Meadowlark Water Reclamation Plant (2.0 mgd and’ Gamer Water
Reclamation Plant (0.75 mgd)
Reservoirs- Two existing steel tank reservoirs, referred to as the “Twin D” tanks, were
converted from potable water storage to recycled water storage having a total
capacity of 2.5 MG.
Pumping Station- A new 2.0 mgd pumping station was constructed. The pumping station
obtains water from the Meadowlark Water Reclamation Plant’s “fail-safe
pipeline” to the ocean. The recycled water is then pumped from the “fail-
safe” pipeline to the “Twin D” tanks.
Pipelines- Transmission pipelines were constructed to deliver recycled water to major customers in the southwest area of Carlsbad. Beginning in 1993, the pipeline
distribution system has been expanded by land development projects
occurring in that area.
Although the Gafner Water Reclamation Facility makes up a part of the recycled water supply for the Phase 1 project, it was not contained in CMWD’s low-interest loan funding program approved by the State Water
. -
Resources Control Board The LCWD obtained their own separate low-interest loan on the facility for fding
of improvements to meet water quality requirements. The water produced by the Gamer Water Reclamation
Plant is piped directly to the La Costa Golf Course and no other pipelines are connected to this supply mce at
this time. Discussions are undenvay with LCWD to construct a connecting pipeline by LCWD to CMWD’s
distribution system.
PROJECT DESCRIPTION
The Encina Basin Water Reclamation Program, Phase II project will be an integral expansion of the
existing Phase I system. It will obtain a supply of recycled water from three treatment facilities and
supply this water to irrigation customers through a pipeline distribution system containing storage
reservoirs and pumping stations. Following is a description of the physical construction and operational
aspects of the project. . . .
The Phase II project includes:
1.
2.
3.
4. . .
5.
6.
7.
Continuation of two existing supply sources, the Meadowlark Water Reclamation Plant (MWRP) at 2
mgd, and the Gafner Water Reclamation Plant at 1 mgd.
Construction of a new advanced tertiary water reclamation plant, referred to as the Carlsbad Water Recycling Facility (CWRF). It will have an initial capacity of 5 million gallons per day (mgd). The
site has been designed with possible future expansions to 16 mgd, to be considered under a future
phase which is not a part of this project.
Construction of approximately 10 miles of trans&ission and distribution pipelines, and water services
to irrigation customers. Pipeline sizes will range in size from 4-inches to 24-inches in diameter.
Construction of three pump stations to supply water to higher elevations in the pipeline distribution
system. The pump stations are located in the southeast portion of the Calavera Hills community, near
Calavera Lake; on the east of the El Camino Real, just south of the Palomar Airport Road
intersection; and at the existing “Twin D” reservoir site near the intersection of Poinsettia Lane and
Black Rail Road.
Construction of improvements to the existing 54 million gallon (MG) Mahr Reservoir with the
purpose of maintaining the quality of the stored water :
Conversion of two existing potable water storage tanks (i.e. “c” and ‘E” Reservoirs) to recycled
water. . .
Construction of one 10 MG secondary flow equalization basin under the Phase II project. Ultimately
up to three 10 MG secondary flow equal&&on basins would be built. These basins equalize peak
flow to the CWRF and the Encina Water Pollution Control Facility’s ocean outfall. . . .
The Recycled Water Plant - Car1sba.d Recycled Water Facility (CRWF)
The recycled water plant .will be constructed as a new advanced tertiary recycling water plant. A portion
of the secondary effluent from the EWPCF, that is now disposed of through an outfall pipeline to the
Pacific Ocean, will be diverted to the proposed water recycling plant. A secondary effluent pump station
will first pump the water to “flow equalization basins*‘. Stored flow is then pumped by an influent pump station to parallel treatment trains: one including continuous backwash filters and the other providing
microfiltration/reverse osmosis (MFRO) treatment to reduce salinity of the treated water. The salinity is
referred to.as total dissolved solids (TDS). The treated water from both trains will be combined having a
maximum TDS of 1,000 mg/L, and then disinfected in a chlorine contact basin. The disinfected water will
then be conveyed to a recycled water storage tank where a pumping station will pump the water into a
pipeline distribution system. A schematic flow diagram of the process is shown on Figure 2.
Secondary Effluent Pumping - A pumping station will be constructed at the existing EWPCF to
intercept secondary effluent flows prior to the ocean outfall. A forcemain would be used to convey the secondary effluent south to the proposed water recycling plant.
Flow Equalization Bask - Prior to being treated at the proposed water recycling plant, the flow will enter a fully enclosed equalization basin. The equalization basin will serve two purposes. First, it will
,
equalize flow to the ocean outfall during times of peak flow. This is most iikely to occur during the winter
season. The flow equalization basin will also serve to store/equalize flow to the proposed water recycling
plant.
Influent Pumping Station - A pumping station will be located at one end of the flow equalization basin
to convey secondary treated flow to either the continuous backwash filters or to the MFIRO system. The
pumps and control system will be contained inside a building.
MF/RO Process - A portion of the flow will be demineralized to reduce the TDS to a maximum of 1,000
mg/L. This is a membrane process consisting of microfiltration (MF) and reverse osmosis (RO). After
adding sodium hypochlorite to the secondary effluent, the water will enter microfiltration membranes to
remove suspended and collodial solids. Sulfiuic acid and a threshold inhibitor are then added and the
water is processed through RO membranes. The RO system will separate the flow into a concentrate
stream and a purified permeate stream. The concentrate stream having a TDS of approximately 9,270
mgL will be conveyed directly to the EWPCF ocean outfall. The purified permeate having a TDS of 40
mg/L will be blended with the filtered bypass stream to become the blended “product water”. The MF/RO
membrane process elements are summarized below:
Microfiltration - These are membranes consisting of either symmetrical hollow fibers fabricated from
polypropylene packed in a pressure vessel with dimensions of 4-inches in diameter by 48 inches in
length, or hollow tine fibers fabricated from polyvinylidene fluoride packed into a pressure vessel
with dimensions of about 6 inches in diameter by 80 inches in length.
Cartridge filters - These are stainless steel housings containing 20 micron polypropylene cartridge
filters.
Sulfuric acid storage - A 2,000 gallon tank will be installed to store sulfuric acid. The tank will also
be enclosed in a containment area to control accidental spillage.
Pumps will be used to maintain pressures between 100 psig and 300 psig for the RO.
Spiral wound RO elements - These will be 8 inches in diameter by 40 inches in length and 400 square
feet in area.
A decarbonator - This is a packed column over which RO permeate is allowed to flow, and where the
permeate is stripped of carbon dioxide. The decarbonator is a tank 8-feet in diameter and
approximately 30-feet in height.
A clean in place system - Consisting of a tank in which cleaning chemicals are mixed with permeate
and heated with an electric heater.
A membrane flushing tank - Consisting of a fiberglass tank, 8-feet in diameter by 25feet in height, in
which permeate is stored and used for flushing the RO system when it shuts down.
All the equipment in the MFRO process will be either covered by a canopy structure or within a fully
enclosed structure. The specifics will be determined as part of the City’s development review process.
Filtration Process - The water is also subject to a filtration process which removes suspended solids.
Before secondary effluent enters the filters, sodium hypochlorite is added to maintain a chlorine residual
of 3 mg/L, and a coagulant aid polymer is added to assist in removing collodial and suspended solids. The
water will then enter a continuous backwash upflow, mono-medium filter; “Dynasand” Filter. The filtered
water twill have a TDS of 1,400 mg/L and be blended with the MF/RO process treated water. The backwash from the Dynasand filter will be conveyed back to the EWPCF for removal. Prior to conveying
the backwash water to the EWPCF the flow will be processed though a solids contact clarifier to thicken
the removed collodiai matter and reduce the amount of water in the backwash. The final “product water”
will be blended with the MFIRO water, and will have a maximum TDS of 1,000 mg/L. The filtration
fac1ln-y would be contamed In an area of approxrmately 2,600 ft’. This area is comprised of concrete filter
cells. influent channel, reject water piping (to convey reject water back to EWPCF), effluent piping, and
an atr compressor.
Ultraviolet Irradiation (L!V) - Filtered water is disinfected by flowing past submerged arrays of UV
lamps.
* . -
Chlorine Contact Basin - Water is further treated with chlorine. Sodium hypochlorite will be added to
.the blended MF/RO and filtration process water and placed in a contact basin to provide approximately
120 minutes of contact time to disinfect the blended product water. The contact basin will have a
serpentine type flow that includes three 50-feet long by 10 feet wide by 10 feet deep concrete channels.
Recycled Water Storage Basin - This basin will store recycled water prior to being pumped into the
distribution system. In emergency conditions an isolation pipe connecting the flow equalization basin
with the recycled water storage basin could be opened to provide additional storage of secondary treated
effluent in the recycled water storage basin. When the additional secondary storage is no longer needed,
the recycled water storage basin would be cleaned and disinfected, and placed back into operation for . recycled water storage only.
Recycled Water Pumping Station - This pumping station will deliver the recycled water into the
distribution piping system from the recycled water storage basin. The pumps and controls will be
contained inside a building.
Control Building - The CWRF will be designed as a fully automated system. However, operation and
maintenance activities will be performed, and consideration will be made to allow visitors tour the
facility. For these purposes a control building is included in the CWRF. The control building will have a
control room housing computer control equipment, an operations office, a plan room (to store plans,
specifications, records, and shop drawings), a small lab for minor water quality analyses, a parts and maintenance storage area, and a meeting room for visitors and other purposes.
Site Layout - The site will be adjacent to the south side of the EWPCF. Visitor parking and access to the
CWRF will be provided along Avenida Encinas; however, a small access road will be constructed from
the EWPCF directly to the CWRF for operation and maintenance personnel access. The control building
will be on the west side of the site near Avenida En&as. immediately east of the control building are the
treatment processes and the chemical storage tanks. Further to the east near Interstate 5 will be the flow
equalization basins, and the influent and recycled water pumping stations. The secondary effluent
pumping station will be located on the EWPCF property near the secondary clarifiers. The pumping
stations will be in buildings. A site layout of the CWRF is shown on Figure 3. The layout shows the area
required for the Phase II project and ultimate buildout requirements as dashed lines. which are not a part
of this project. The perimeter of the site will be landscaped. A landscape concept is shown on Figure 4.
Booster Pumping Stations
To provide water service to the higher elevations in the distribution system at a desirable pressure
requires three booster pumping stations in addition to the pumping stations at the treatment facilities. One
booster pumping station is planned at the “Twin D” tank site. (See attached Figure 5). A second is
planned at the intersection of Palomar Airport Road and El Camino Real. (Figure 6). A third is planned
in the Calavera Hills Village “T” area on an existing graded pad located on the southeast comer of the
tract boundary. (Figure 7).
Distribution Pipelines
Pipelines will be required to deliver the recycled water to customers for irrigation uses. The location of the pipelines are shown on Figure 8 and range in size from 4-inches to 24-inches in diameter. New
service pipelmes are also required to supply the recycled water to irrigation meters for each customer.
The majority of pipelines are proposed within existing, improved street rights-of-way. Other segments
are proposed in existing unpaved utility access roads. Others transect landscaped areas or natural areas.
In this case a directional drilling technology will be employed to minimize disruption to those areas. The
directional drilling technology is a trenchless technology.
Reservoirs
Reservoirs will be needed to store water to meet peak recycled water demands. The reservoirs include the
existing Mahr Reservoir, and “c” and “E” tank reservoirs. The “c” and “E” tanks will not be modified
except they will be converted from potable water to recycled water storage.
Mahr Reservoir - Mahr Reservoir is an earthen dam structure originally constructed to store treated
effluent from the MWRF. Improvements are planned at Mahr Reservoir to maintain the quality of the
stored water. The improvements include a new inlet/outlet structure on the upstream face of the earthen
dam (to allow operators to extract water at different depths), a porous asphalt liner and a floating cover.
In addition, a control building will be constructed for the automatic control valves, and to store sodium
hypochlorite for supplemental disinfection of the stored water, and a small air compressor for an air
injection system consisting of air diffusers in the bottom of the reservoir. A paved access road and
lighting are also incorporated. Refer to Figure 9.

II. EmONMENTALANALYSIS
B. Environmental Impact Discussion
’ 1. LANBUSEANDPLANNING
a. Potentialiy Significant Unless Mitigation Incorporated. The prdposed water recycled plant site is
zoned for, and has a General Plan designation of, planned industrial and off&. The proposed use is
a public utility, which is inconsistent with the current zoning and General Plan designations. The
zone and General Plan designations for the site, or for that portion of the site proposed for public
utiluy use, will need to be changed to Public Utility to allow the, use. A mitigation measure has been incorporated accordingly. The pump station sites are located on properties with various designations
which include residential. Pursuant to the Zoning section of the Carlsbad Municipal Code, pump stations are conditionally permitted uses in all zones and are subject to the conditional use permitting
procedure. The process provides the means to evaluate the appropriateness of particular types of
uses, which because of their nature have the potential to impact surrounding land uses, and to apply
conditions of approval to mitigate those impacts. The submittal, and consideration, of a conditional
use permit is required for entitlement of this project. A mitigation measure has been incorporated.
Transmission pipeline installations are within existing or planned street rights of way or in existing
public utility easements which is consistent with the General Plan and Zoning Ordinance.
b. Potentially Significant Unless Mitigation Incorporated. The City has recently adopted a City-
wide Habitat Management Plan (HMP). The recycled water plant site is vacant, but has been
historically disturbed, and is not identified as a conservation area in the HMP. Additionally, two of
the pump station sites are in disturbed or developed areas, and not identified as a conservation area.
The pump station site proposed near Lake Calavera is in a conservation area, but is adjacent to a
unpaved utility access road and along a slope whose surface has been disturbed and contains no
significant habitat resources. The installation of such water related infrastructure in this conservation
area was acknowledged in the HMP. The majority of pipeline installations are proposed in either
existing street rights of way or in existing utility access roads. Therefore no impacts are anticipated.
A mmlmal amount of pipeline installation will be either through introduced landscaped areas, or
natural vegetation areas. To minimize impacts to natural vegetation areas, a mitigation measure has
been incorporated into the project which requires the use of a micro-tunneling or directional drilling
technology to avoid disruption to those areas. Improvements at the Mahr Reservoir site, may as a
result of the Division of Mines and Geology requirements, necessitate disruption of a potentially
significant area of natural vegetation along the downstream face of the dam. The extent of the
dtsruption, if any, is not known at this time. A mitigation measure is being applied which requires
that the CMWD conduct additional biological surveys and obtain the necessary resource agency clearances in the event of such plan changes, which would occur prior to conducting any work.
The proposed water recycling plant site is located within the Coastal Zone and is subject to the City’s
Local Coastal Program. Any changes to land use designations identified in the City’s General Plan which are in the Coastal Zone, require an LCP amendment as well. Accordingly, a mitigation
measure has been incorporated.
c. Potentially Significant Unless Mitigation Incorporated. Given the proposed public utility use
nature (i.e. antictpated activities. structural installations, appearance etc.), a potential does exist for
Impacts on, or incompatibility with, surrounding land uses unless mitigation is incorporated. The
water recycling plant site is located in an area characterized by a mix of land uses. Potentially
impacted land uses in the vicinity include residential to in east.(on the other side of the freeway) and
a developing multi-family project to the southwest of the site. Also, but to a lesser degree, commercial uses to the south of the sue may be impacted. Mitigation measures can minimize potential Impacts to a level of insignificance and have been mcorporated accordingly. They relate to
requirements that the project complete the City’s development review process and special
requirements for screening of operations and/or enclosure of equipment, enhanced building
architecture, and enhanced perimeter landscaping.
Three pump station sites are proposed. One is proposed in relatively remote location along an
existing, unpaved utility access road near Lake Calavera and impacts/incompatibilities are expected
to be less than significant. Two are located in prominent locations along existing, or planned, major
arterials. Mitigation measures can minimize potential visual impacts to a level of insignificance. The
pump stations are subject to the conditional use permitting and development review process.
Additionally special design requirements, or mitigation, have been developed. For the pump station
proposed near the comer of El Camino Real and Palomar Airport Road, mitigation involves locating
the facility underground and requiring the CMWD to work with the propetty owner in integrating the
installation into monument signage/hardscape and landscaping for the Bressi Ranch, Development.
For the pump station proposed at the existing tank site off Poinsettia Lane, mitigation consists of a
architecturally enhanced structural enclosure and screening landscape.
Pipelines will be within either existing streets rights of way or existing utility access roads and
therefore unobtrusive. Improvements at the existing Mahr reservoir site are similarly unobtrusive to
surrounding land uses and will not appreciatively change the existing visual quality of the site.
d. Potentially Significant Unless Mitigation Incorporated. The site of the proposed water recycling
plant has been identified in the City’s Local Coastal Program as property historically used for
agriculture. The site, however, has been identified as “non-prime agricultural lands” which can be
converted to urban use by the applicant’s participation in the Agricultural Conversion Mitigation
program. A mitigation measure has been incorporated accordingly. The pump station sites, pipeline
locations, and existing Mahr Reservoir site are not located in, or near, agricultural areas and,
therefore, will not affect agricultural resources.
e. No Impact. The proposed water recycling plant site is located on property situated in between the I-5
Freeway and Avenida Encina in the east and west, and an existing water treatment plant and
commercial uses in the north and south. No disruption or division of an established community is
anticipated as a result implementation of the water recycling plant. Pipeline construction will be
underground, in street rights of way or other public utility easements, and will not physically divide
any established community. Pump station sites are small and situated such that they will not disrupt
or divide any established community.
II. POPULATION AND HOUSING
a. No Impact. The proposed project involves no addition, or removal, of residential uses and, therefore,
will not cause changes in. regional and local population projections.
b. Less than Significant Impact. In addition to general resource conservation, a primary goal of the
proposed projecdprogram is to reduce the City’s reliance on imported water sources provided by the
Metropolitan Water District (MWD). Carlsbad’s anticipated reduced need for imported water could,
in theory, mean that additional water resources are made available to other MWD customers, which
could have growth inducing impacts either directly or indirectly. The amount of water that could be made available to others is 4 MGD - the capacity of the proposed system. Given that relatively small
amount of water within the diverse context of the MWD market (i.e. customers such as agriculture,
industry, residential and a service area covering all of Southern California), the potential for growth
induction seems less than significant. At the local level, additional water resources are not expected
to induce growth. Growth in the City of Carlsbad is regulated and numerically capped by the City’s
Growth Management Program.
. .--N
c. No Impact. The proposed water recycling plant and pump station sites are proposed on vacant
properties, proposed pipelines are within existing street rights of way or public utility easements, and
improvements at the Mahr reservoir and Encina Watewater Treatment are at existing facilities,
therefore, the project will not displace existing housing.
III. GEOLOGIC PROBLEMS
a. No Impact. The City of Carlsbad General Plan does not identify any geologic fault across the
proposed water recycling plant site. The nearest fault system, Rose Canyon Fault, is shown to be
located within 4 miles of the site. The geotechnical report prepared for the 1996 extension of Avenida
Encinas also concluded that there are no faults crossing the plant site. Other components of the
project, pipelines and pump stations, are not expected to be impacted by fault ruptures.
b. Less Than Significant Impact. Although no faults occur within the project boundaries, the proposed
project is within a seismically active region. All structures will be designed to comply with the
Uniform Building Code which represent currently accepted earthquake design standards. The
project’s compliance with UBC will be ensured through the City’s development review and
permitting process. Additionally, it is anticipated that workers will not be permanently stationed at
the site. The operation and maintenance personnel and the general public will infrequently visit the
plant facility. The water reclamation plant will be attended to by operation and maintenance staff,
only, on a low frequency basis; and therefore, people exposed to seismic shaking while at these sites
will be very low.
. .
c. Less Than Significant Impact. Ground failure or liquefaction could occur in conjunction with a
major seismic event. However, for the proposed water recycling plant site, previous investigations
indicate a very low potential for liquefaction and ground failure. Reference is made to a geotechnical
report prepared by Geocon Incorporated, dated February 14, 1996 that investigated the potential for
liquefaction on adjacent property to the south referred to as “Poinsettia Properties”. The report
concluded the following: “Due to the dense to very dense condition of the underlying formational soils on the site and the recommended recompaction of the topsoil’s and alluvial soils the potential
for seismically induced liquefaction of the onsite soils is very low.” In addition to this, the
geotechnical report for the 1996 extension of Avenida Encinas states that “No evidence of perched
groundwater was observed in the temtce deposits along the southern portion of the site.” The design
of the proposed water reclamation plant will require specific geotechnical studies as a pa,rt of the
design process. The recommendations in the geotechnical report will provide information regarding
recompaction efforts for the proposed project to achieve adequate foundation conditions for
structures which will be ensured through the City’s development review and permitting process.
The property for the “Twin D” booster pumping stations has no potential for liquefaction based on a
previous geotechnical study prepared by Leighton & Associates dated October 2, 1990. It was
concluded that “The onsite materials below the ground water table are not considered liquefiable due
to their high density characteristics, along with low ground water table elevation”. No problems were
indicated for the El Camino Real /Palomar Airport Road Site according to the report prepared for the
widening of Palomar Airport Road titled “ Geotechnical Report for Palomar Airport Road East to El
Camino Real”, dated September 27, 1990. Finally, no liquefaction potential was indicated for the
Calavera Hills Village- “T’ site as indicated in the Geotechnical Report prepared in 1990 for Calavera
Hills Subdivision.
d. No Impact. The project would not result in or expose people to seiche, tsunami, or volcanic hazards.
e. Less Than Significant Impact. The topography on the proposed water recycling plant site consists
of basically level terrain with elevations ranging from 55 to 65 feet above sea level. The ground
slopes from the north east comer to the southwest comer at approximately 1.3 feet per 100 feet of
length. The land was cultivated in the past as noted on several maps including the geotechnical report
for Avenida Encinas Road Extension, and the appraisal report by Donald P. Falk in 1994. No
problems with mudflows have occurred or were noted. The land around the site is improved with a
major freeway (Interstate 5) and collector roads and the lands adjacent to these roads slope away
from the site; and therefore, there is no potential for landslide or mud flows coming from adjacent
properties on to the site.
The pump station, at the “D” tank site, could be placed at two locations. One location would be on
relatively level ground. The other location would require a retaining wall within a cut slope to
construct any building. No landslide would occur because the design will require a geotechnical
report to develop temporary shoring for any construction including permanent retaining walls if
required. Similarly, the pump station site near Lake Calavera would require a retaining wall within a
cut slope to construct any building. Again, no landslide would occur because the design will require
a geotechnical report to develop temporary shoring for any construction including permanent
retaining walls if required, which will be ensured through the City’s development review and
permitting process. The pump station site near the intersection of Palomar Airport Road and El
Camino Real, is on relatively level ground with improved roads on the east and north sides, and no
problems are anticipated at that site.
The pipelines will be constructed using normal trenching operations with worker shoring protection
required. No impacts are anticipated.
f. Less Than Significant Impact. Erosion occurs when soil particles are dislodged by air, water, or
human activity. For the proposed water recycling plant site, some grading of the top soil would occur
in order to construct access and maintenance roads, excavations for concrete tanks and pipelines and
for final site grading. It is anticipated that the equalization basins would be constructed partially at
grade. It is not anticipated that any significant changes in topography will be as a result of this
project.
Regarding erosion, according to the Soil Conservation Service maps, sheet 23 Encinitas Quadrangle,
the soil type is “Marina loamy course sand, 2 to 9 percent slopes”. The soil erodibility is listed as
“Severe 2” which indicates that protective and corrective measures are needed before and during the
time the soil is used or graded. However,. the geotechnical report prepared for the extension of
Avenida Encinas does not indicate any problem with erosion. Erosion impacts will be mitigated by
employing Best Management Practices, in accordance with the Regional Water Quality Control
Board (RWQCB) and City requirements to ensure that soil erosion does not occur during
construction. Final site grading would be followed by paving of access roads, installing curbs and
gutters and installing landscaping to stabilize any slopes that might be constructed. . .
The pump station at the Twin D site are listed as Chesterton fine sandy loam, 5 to 9 percent slopes,
Severe 9 erodibiliry index. The previous soil report for this site by Leighton & Associates indicate
that erosion can be controlled by constructing berms or swales along the top of slopes and lot
drainage directed such that surface runoff on the slope faces be minimized. Little or no problems
were noted in the geotechnical reports for the other two pump station sites. The latest Regional Water
Quality Control Board and City ordinances shall be used to mitigate excessive site erosion during
construction. Best Management Practices will be used to mitigate runoff and soil erosion should it
occur.
The pipelines will be within paved roads and not pose any serious erosion problem. The paving will
be cut for pipeline trenches and the earth removed will be stockpiled along the trench. Upon
installation of the pipeline the earth removed will be recompacted in place, and the excess hauled
away to an approved location. Pipeline construction will not occur during wet weather periods.
To mitigate any temporary water or wind erosion impacts associated with construction activities, standard erosion control measures such as sandbagging, vegetation planting and watering shall be
developed prior to construction.
.-
All aspects of the projec;’ are subject to the City’s grading and erosion controls standards ‘and
requtrements which will be ensure through the City’s development review and permitting process.
g. No Impact. None of the geotechnical reports reviewed for this project reference any potential for
subsidence. Additionally, standard engineering practices for recompaction, fill placement, etc. will be
utilized during construction.
h. Less than Significant Impact. For the proposed water recycling plant site, previous geotechnical
reports indicate that the alluvial soils possess highly expansive characteristics. One geotechnical
report for the adjacent property, “Poinsettia Properties”, stated that expansive soils can be mitigated
by placing it such that it is not within 3-feet of finish grade. Another report for construction of
Avenida Encinas stated that the upper approximately 36 inches of these materials should be removed’
.
and recompacted. These or other standard practices will be incorporated into the project. design,
which will be ensure through the City’s development review and permitting process, resulting in less
than significant impacts.
For the pump station sites, expansive soils were not encountered based on previous geotechnical
studies. Expansive soils may be encountered along the pipeline routes. However, no impact will
occur to people as a result. . .
i. No Impact. There are no unique geological or physical features associated with the proposed water
recycling plant and pump station sites, or along the proposed pipeline routes.
IV., WATER
a. Less Than Significant Impact. Construction of paved areas, concrete tanks and buildings will
decrease absorption rates and increase the amount of surface runoff at the proposed water recycling
plant site, compared to the existing conditions. Full street and drainage improvements along the site
frontage will be required of the project as part of the development review process, mitigating the
potential for impact to a level of insignificance. With regard to the pump station sites, given their .
small surface area, the impact is expected to be less than significant. No impact is anticipated from
the pipelines, since they will be either underground and/or underneath existing paved areas.
b. No Impact. According to Flood Map 060285-0004D dated g/18/87, the site for the proposed water
recycling plant and pump station sites are located in Zone C, which is not an area considered prone to
flooding.
c. Less Than Significant Impact. No long term discharge into surface waters or alteration of surface
water quality is anticipated as result of this project. The project, in fact, will decrease the amount of
effluent currently being discharged into the ocean by the Encina Water Treatment Plant (i.e..effluent
otherwise being discharged will be treated by the proposed water recycling plant and sent back to the
community for landscape and agriculture irrigation). In the short term, some groundwater may be
discharged into the ocean, via the Encina Plant and associated with dewatering of the site during
construction activity. However, given the small amount, quality, and relative compatibility of the
ground water discharge into the ocean, adverse impacts are not anticipated.
d. No Impact. Groundwater discharge into the ocean as a result of dewatering associated with
construction will not impact the amount of surface water in the ocean.
e. No Impact. The nature of the project precludes changes in water movement. The project does not
impact any steams or water courses. ‘.
f. Less than Significant Impact. The nature of the project precludes changes in the direction or rate of
flow of ground water. Although the ground water quality is poor and cannot be used beneficially, the
levels of the groundwater may be high, based on geotechnical reports at the site for the proposed
Plant site. Therefore, groundwater levels may need to be controlled should they become too high.
Since part of the project envisions in ground tanks, pipelines or storage basins some dewatering
during construction may be necessary. Any groundwater removed during construction will be
conveyed to the Encina Water Pollution Control Facility for treatment and final ocean discharge. (See
discussion under IV c above regarding discharge into a surface water body).
’ g. No Impact. The project will not change groundwater direction or rate of flow of groundwater. No
wells are proposed. No permanent excavations to the depth of groundwater levels are proposed.
h. No Impact. No changes will occur to the groundwater quality from this project. The existing
groundwater quality is very poor and not useable for public water systems, according to the Water
Quality Control Plan adopted by the San Diego Regional Water Quality Control Board, June 1994.
The water produced for irrigation will be much higher quality than the existing groundwater at all
locations in the City. The TDS levels of the water produced by the project will be less than 1000
mg/L.
i. No Impact. No public water supply groundwater will be pumped or removed by this project.
V. AIR QUALITY
a. Less Than Significant Impact. The project individually would not result in a violation of air quality
standards. No additional employees, and the resulting vehicle trips, are anticipated. However, the
emissions resulting from construction equipment and activity in the short term and the emission from
long-term plant operations, where within acceptable limits individually, cumulatively contribute to
the poor air quality of the region. To minimize excess pollution caused by dust generated during site
preparation operations, construction sites will be watered prior to and during grading. Any internal
combustion engines used for construction activities will be operated for minimum amounts of time to
accomplish tasks and will be maintained in good running order to minimize adverse products of
combustion. The impacts in this case are considered to be less than significant.
b. Less Than Significant Impact. The project would be built using standard construction methods for
reinforced concrete structures, buildings, perimeter walls and pipelines; and therefore, would not
expose sensitive receptors to pollutants as a result of plant/program operations. Short-term.
construction activities for project facilities will produce additional air pollutants, mainly products
from diesel exhausts and dust from grading activities. To minimize excess pollution caused by dust
generated during site preparation operations, construction sites will be watered’.prior to and during
grading. Any internal combustion engines used for construction activities will be operated for
minimum amounts of time to accomplish tasks and will be maintained in good running order to
minimize adverse products of combustion. The impacts in this case are considered to be less than
significant. ,,
‘.
c. Nd Impact. The nature of the project precludes any alteration of air movement, moisture, or
temperature, or cause any change in climate.
d. Less Than Significant Impact. The proposed water recycling plant will generate a small degree of
odor, but it is considered to be less than significant. Odor generation will be mild because the proposed water recycling plant is filtering/treating only secondary treated effluent that is now
discharged to the ocean. Chemicals proposed for use in the treatment process will be in enclosed
contamers and will not be vented to the atmosphere. During refilling of the sodium hypochlorite
containers it may be possible to detect a bleach type odor when standing next to the container.
However. this bleach odor will dissipate and will not be detectable within 50-feet of the container.
No odors are anticipated from the pipelines or booster pump stations because they contain only
recycled water.
-.
VI. TRANSPORTATluN
a. Less Than Significant Impact. The amount of projected daily traffic anticipated as a result of the
project, short and long term, is minimal. Therefore traffic impacts are expected to be less than
significant. To minimize the potential for short term impacts relating to construction traffic, the
project is subject to the City’s haul route permitting procedure. In the long term, a minor amount of
additional traffic is anticipated to be generated from the project. The proposed water reclamation
plant will be fully automated, and only daily site visits will be performed. Although no agreement has
been prepared, it is anticipated that a contract with Encina Wastewater Auth&ity will be established
to provide operation and maintenance of the facility. Therefore, no additional staffing is required. It is
planned that an access road will be constructed from the Encina Water Pollution Control Facility to
the water reclamation plant to enhance access for operation and maintenance personnel which would
remove any traffic on existing public roads. When the water reclamation plant is in operation, only
periodic monthly deliveries of treatment chemicals are required. The booster pumping stations and
pipelines will be operated and maintained by,existing staff at the water recycling plant. The pumping
stations will be automated and only periodic site visits are anticipated. Mahr Reservoir will have
routine site visits for security and to verify operation of the valves. It is planned that twice a year that
cleaning of the cover will be performed. These cleaning activities may be contracted ous and
therefore, a minor amount of additional traffic, on a temporary basis, would be generated during this
time. The cleaning time period is estimated at 4 to 5 days.
b. No Impact. Do to the nature of the project no road hazards would be created. Access roads at the
CWRF will be designed to accommodate the general public for visits and chemical delivery trucks.
c. Less Than Significant Impact. During construction of the project, emergency access may be
temporarily disrupted. An aspect of the project involves the installation of pipeline in existing road
rights of way. The disruption is not expected to be significant however, since construction would be
limited to a narrow strip along the edge of the road
d. No Impact. The facility is primarily self operating and will generate little need for parking. It is
expected however that demonstration tours will be given occasionally. Adequate space exists and
adequate on-site parking will be provided, which will be determined/ensured through the
development review process.
e. Less Than Significant Impact. No hazards or barriers for pedestrians or bicyclists will be created. In
the short term, the pipeline and plant construction activities may temporarily require rerouting
pedesmans and bicyclists around the c’onstruction areas. The specifications for pipelines shall address
the need to create alternative routes during construction as required by the City of Catlsbad and
identified through the development review process.
f. Xv0 Impact. Do to the nature of the project no conflicts will be created with alternative transportation
plans.
g. No Impact. No rail, waterborne or air traffic impacts will be created.
VII. BIOLOGICAL RESOURCES
a. Potentially Significant Unless Mitigation Incorporated. The City has recently adopted a City-
wide Habitat Management Plan (HMP). The recycled water plant site is vacant, but has been
historlcally disturbed and is not identified as a conservation area in the HMP. Additionally, two of
the pump station sites are in disturbed or developed areas, and not identified as a conservation area. The pump station site proposed near Lake Calavera is in a conservation area, but is adjacent to a
unpaved utihty access road and along a slope that has been disturbed and contains no significant
habitat resources. The installanon of such water related Infrastructure in this conservation area was
acknowledged In the HMP. The majority of pipeline installations are proposed in either existing
street rights of way or in existing utility access roads. Therefore no impacts are anticipated. A
,
minimal amount of pipeline installation will be either through introduced landscaped areas, or natural
vegetation areas. To minimize impacts to natural vegetation areas, a mitigation measure has been
incorporated into the project which requires the use of a micro-tunneling or directional drilling
technology to avoid disruption to those areas. Improvements at the Mahr Reservoir site, may as a
result of the Division of Mines and Geology requirements, necessitate disruption of a potentially
significant area of natural vegetation along the downstream face of the dam. The extent of the
disruption, if any, is not known at this time. A mitigation measure is being applied which requires
that the CMWD conduct additional biological surveys and obtain the necessary resource agency
clearances in the event of such plan changes, which would occur prior to conducting any work.
b. No Impact. There are no locally designated species on any of the impacted sites.
c. Potentially Significant Unless Mitigation Incorporated. See response to VII a above.
d. No Impact. .Based on a review of previous geotechnical studies, a limited site investigation report,
and appraisal report, there are no wetlands, marsh, riparian or vernal pools on the properties impacted
by the project.
e. No Impact. There are no wildlife dispersal or migration corridors impacted by the project.
VIII. ENERGY AND MINERAL RESOURCES.
a. No Impact. There is no conflict with adopted energy conservation plans.
b. No Impact. The proposed project will not use non-renewable resources in a wasteful manner. The
project will recycle water that is now discharged to the ocean.
c. No Impact. Due to the nature of the project there will be no loss of availability of a known mineral
resource.
IX. HAZARDS
a. Potentially Significant Unless Mitigation Incorporated. In processing the wastewater, chemicals
are used to assist in the treatment process and to clean membranes for microfiltration and reverse
osmosis. These chemicals are in sealed containers and are injected into the treated flow stream. These
chemicals do not normally come into contact with people. The chemicals proposed for use are as
follows:
Sodium hypochlorite 12.5% will be stored onsite in an 8,000 gallon tank. The chemical will be
injected upstream of the treatment units and also for final disinfection to maintain a chlorine
residual in the treated effluent. Two tanks may be installed to store the chemical. Periodic
refilling of the tanks will be handled by the chemical supplier. The tanks are sealed and no odors
are emitted from the tank(s) during operation. A small insignificant amount of a bleach type odor
may be released during the filling process; however, it will not be detectable within a short distance from the tank. It has a very low vapor pressure and therefore negligible volatility. Spills
of sodium hypochlorite can be neutralized using sodium bisulfate or ferrous salt solutions. If neuualization is required, all neutralized materials are to be stored in approved Department of
Transportation containers. After removal of the neutralized material, the area should be flushed
Lvith large amounts of water. Sodium hypochlorite is corrosive, but it is not explosive nor
flammable. It is classified as a hazardous material under federal guidelines due to its pH of 12.5
to 13.5. This chemical is presently used at the EWPCF and maintenance personnel are familiar
with its handling requirements.
With a microtiltration/reverse osmosis reclamation plant the following chemicals would be used to periodically clean the membranes.
-
Microfiltration Cleanine:
Sodium Hydroxide stored in two 55 gallon drums.
Citric acid stored in a 2500 pound container.
Memclean (surfactant) stored in one 55 gallon drum.
Argo Scientific Hypersperse AF 200 will be delivered in 250 gallon tote bins.
Sulfuric Acid will be delivered to onsite storage tanks approximately 2000 gallons in capacity.
Reverse Osmosis Cleaniw:
Sodium Dodecylbenzenessulfonate (a surfactant) stored in a 100 pound container.
Sodium tripolyphosphate stored in a 2500 pound container.
Sodium Hydroxide 25% stored in one 55 gallon drum.
Each tank, container or drum will have an enclosure around it to contain any accidental spillage. The
enclosure consists of concrete basins with sufficient wall height to contain the volume of chemical in each container. The tanks will be placed in an area to control accidental spillage should it occur.
. .
Accidental spills or leaks of treated secondary or tertiary wastewater, hazardous chemicals or certain
construction materials are considered to be potentially significant project impacts. The use of
standard design measures such as shutoff valves, monitoring systems and containment structures will
reduce this potential impact to an insignificant level. The project will be subject to review by the San
Diego County Department of Health Services and the Regional Water Quality Control Board, San
Diego Region. These reviews ensure compliance with all regulations related to public health and
safety, as well as water quality: Additionally, to mitigate the potential for impact a mitigation
measure has been incorporated which requires the applicant to comply with all the requirements of
the Carlsbad Fire Prevention Services Division (i.e. a hazardous substances management/storage
plan) prior to the issuance of permits.
b. No Impact. The project will not interfere with any emergency response plan or emergency
evacuation plan. Access along roadways will be maintained during project implementation.
c. Potentially Significant Unless Mitigation Incorporated. See the response to IX a above.
d. No Impact. The project will not expose people to existing sources of potential health hazards. A
health risk study report was prepared by Dudek & Associates regarding investigation of the site for
hazardous chemicals due to past farming operations. In the summary of findings section it was
reported that the aggregate incremental risk of cancer in the most sensitive target populations from
exposure to the various pesticides present in the on-site soils was not calculated to be greater than one
excess cancer risk in an exposed population of 100,000, where it is necessary to provide notice of the
presence of the pesticides in compliance with Proposition 65. The report states that according to the
State of California, this determination indicates that additional measures in the name of protecting
human health from carcinogenic effects are not warranted.
Ko hazardous materials are anticipated to be encountered ar booster pumping stations, reservoirs or
pipelines. Individual geotechnical reports will be required for the pipelines, and any contaminated
soil found along the pipeline alignments will need to be disposed of at a licensed landfill.
e. No Impact. The project will not increase fire hazards. Based on site visits there is no brush covering
the areas where rmprovements are proposed. No heat producing elements are part of this project
26 Rev. 03/28/96
-.
except for the standby generator at the water reclamation plant. This heat will be contained in a
building and will be dissipated thrqugh a ventilation system.
x. NOISE
a. Less Than Significant Impact. Noise levels will increase as a result of the project since the site is
currently vacant. Sound emissions from the project will occur at the CWRF, booster pumping
stations and the compressor at Mahr Reservoir. Noise will be from the operation of pumps, electric
motors, standby generators and compressors. The motors will be specified to limit noise emissions to be below limits established by the City of Carlsbad. In addition, motors will be in enclosures or
buildings that will be sound attenuated. The standby power generator will be at the CWRF, and will be diesel engine driven. It will be enclosed in a building incorporating sound attenuation material on
the walls and all vent openings to limit the sound emissions to meet hospital zone requirements.
There will be noise on a temporary basis during construction. At the site for the proposed CWRF the
area has a limited noise sensitivity. Local traffic (especially trucks), as well as the I-5 freeway and
coaster railroad background noise are at very high levels and will mask noise impact potential from
the project site.
During construction n&e levels ‘for the noisiest construction equipment are around 80 dB as a mean
and 90 dB as a peak. During normal working hours these noise levels will not be greater than the
levels normally occurring around the CWRF site. However, construction activities will be prohibited
from 7 p.m. to 7 a.m. and all day on Sundays and holidays, prescribed by the Carlsbad Municipal
Code.
Construction at the booster pumping station sites and the distribution pipelines similarly will not be
an Issue during normal working hours. However, construction will be prohibited during 7 p.m. to 7
a.m. and all holidays and Sundays. In addition, construction equipment shall have manufacturers
noise control devices in place. Short and long term noise associated with the project is expected to be
less than significant.
b. Less Than Significant Impact. The project will not expose people to severe noise levels except for
operators and maintenance people entering the standby power generator building when the generator
is in operation. In this case the operators and maintenance personnel will be required to wear personal
ear protection devices.
XI. PUBLIC SERVICE.
a. No Impact. No additional impacts to City of Carlsbad fire protection as a result of this project.
b. No Impact. No additional impacts to City of Carlsbad police protection services as a result of this
project.
c. No Impact. No additional impacts to schools’as a result of this project except that recycled water will
be made available for irrigation water at some of the schools. The water quality will meet or exceed
the requirements of State Health Services for unrestricted use of the recycled water.
d. Ko Impact. No additional impacts to maintenance of existing public facilities or roads.
e. No Impact. No additional impacts to other governmental services.
XII. UTILITIES AND SERVICE SYSTEMS
3. 30 Impact. The project is not of a scale to create a need for new power or natural gas systems.
b. No Impact. The project will not result in a need for new communication systems.
27 Rev. 03/28/96
c. No Impact. The project will not impact regional or local water treatment or distribution systems.
However, additional water will be produced from the project which will lower the demand for potable
water at some existing irrigation sites.
’ d. No Impact. The project will not impact existing sewer or septic tanks.
e. No Impact. No new storm drains or channels are required for this project. The sites are not within a
loo-year flood plain.
f. No Impact. The project will not impact solid waste disposal systems. . .
g. No Impact. The project will not impact local or regional water supplies. However, additional treated
potable water would be made available since the project will produce recycled water for irrigation
and industrial purposes.
XIII. AESTHETICS.
a. No Impact. No designated Scenic Highway or route or general public, scenic vista will be impacted
by the project. . .
b. Potentially Significant Unless Mitigation Incorporated. Given the nature of the proposed public
utility use (i.e. anticipated activities, structural installations, appearance etc.), a potential does exist
for adverse visual impacts on surrounding land uses unless mitigation is incorporated. The water
recycling plant site is located in an area characterized by a mix of landuses. Potentially ‘impacted
land uses in the vicinity include residential to in east (on the other side of the freeway) and a
developing multi-family project to the southwest of the site. Also, but to a lesser degree, commercial
uses to the south of the site may be impacted. Mitigation measures can minimize potential impacts to
a level of insignificance and have been incorporated accordingly. They relate to requirements that
the project complete the City’s development review process and special requirements for screening of
operations andlor enclosure of equipment, enhanced building architecture, and enhanced perimeter
landscaping.
Three pump station sites are proposed. One is proposed in relatively remote location along an
existing, unpaved utility access road near Lake Calavera and impacts/incompatibilities are expected
to be less than significant. Two are located in prominent locations along existing, or planned, major
arterials. Mitigation measures can minimize potential visual impacts to a level of insignificance. The
pump stations are subject to the conditional use permitting and development review process.
Additionally special design requirements, or mitigation, have been developed. For the pump station
proposed near the comer of El Camino Real and Palomar Airport Road, mitigation involveslocating
the facility underground and requiring the CMWD to work with the property owner in integrating the
installation into monument signage/hardscape and landscaping for the Bressi Ranch Development.
For the pump station proposed at the existing tank site off Poinsettia Lane, mitigation consists of a
architecturally enhanced structural enclosure and screening landscape.
c. Potentially Significant Unless Mitigation Incorporated. There will be outside lighting at the
proposed water reclamation plant. However, all exterior and parking lot lights will be of low reflective mercury or sodium vapor type. The booster pumping station sites will have security
lighting only at major doorway entrances.
XIV. CULTURAL RESOURCES.
a. No Impact. The proposed water recycling plant site, 2 pump station sites, pipelines and work
proposed at the Mahr reservoir site are in areas already disturbed by grading, agricultural cultivation
or previous excavations for adjacent structures. Therefore no impact to paleontological resources is anticipated. For the third pump station site proposed near the Lake Calavera, recorded
28 Rev. 03/28196
-
paleontological resource maps on tile in the Planning Division indicate concentrations of resources
near the site. The distance is far enough however that no impact is anticipated.
b. Potentially Significant Unless Mitigation Incorporated. As indicated above, the proposed water
recycling plant site, 2 pump station sites, pipelines and work proposed at the Mahr reservoir site are
in areas already disturbed by grading, agricultural cultivation or previous excavations for adjacent
structures. Therefore no impact to archeological resources is anticipated at those sites. For the third
pump station site proposed near the Lake Calavera, however, recorded archeological resource maps
on file in the Planning Division indicate concentrations of resources in close proximity to the site.
Since archeological resources often tend to be’scattered, a potential does exist that resources may be
located on the pump station site. Based on staffs review of the records it does not appear that any
resources would be considered a “unique archeological resource” as defined in Section 21083.2 of
CEQA. (Provided they are, and in all likelihood they would be, similar to recorded finds .in the
vicinity). Nonetheless, any resource would have value and a mitigation measure has been
incorporated into the project that requires that the CMWD have a qualified archeologist on-site
during excavation to recover any resources which are found..
c. No Impact. Based on site visits and historical use of the properties, there are no historical resources
on any of the sites.
d. No Impact. There are no unique ethnic cultural impacts associated with any of the locations. None
were identified in adjacent land development projects.
e. No Impact. There are no existing religious uses within the proposed sites.
xv. RECREATIONAL.
a. No Impact. The project will not result in the need for more parks or other recreational facilities.
b. No Impact. The project will not impact any existing recreational opportunities such as parks, public
trails, beach access etc.

Metropolitan was incorporated under the Metropolitan Water District Act (Act) for the
purpose of developing, storing, and distributing water for domestic and municipal
purposes;
The Act empowers Metropolitan to acquire water and water rights within or without the
state; develop, store and transport water; provide, sell and deliver water at wholesale for
municipal and domestic uses and purposes; set the rates for water; and acquire, construct,
operate and maintain any and all works, facilities, improvements and property necessary
or convenient to the exercise of the powers granted by the Act;
Authority, as a member public agency of Metropolitan under the Act, is a wholesale
purchaser within its service area of water developed, stored, and distributed by
Metropolitan;
Carlsbad is a member public agency of Authority and provides domestic and
nondomestic water services entirely within Authority’s service area;
Carlsbad is empowered under Section 7 1309 of the Water Code to enter into contracts
necessary to carry out its powers and purposes;
Metropolitan’s water supply and demand projections for its service area, including that
encompassed by Authority, show that additional sources of supplemental water must be
developed to meet future needs; -
Metropolitan has determined to take all necessary steps to provide its service area with
adequate and reliable supplies of high quality water in the years ahead in an
environmentally and economically responsible way, including providing financial
incentives to water recycling projects under its Local Resources Program (LRP);
Metropolitan and Authority have determined that it is mutually beneficial for local water
projects originating in Authority’s service area to be developed as a supplement to
Metropolitan’s imported water supplies in order to meet future water needs;
A significant amount of treated wastewater generated within Authority’s service area is
currently discharged to the ocean, which water when provided with tertiary treatment
could be used for non-potable purposes;
Additional quantities of recycled water could be produced, distributed, and sold by
Carlsbad by means of additional capital facilities to treat, distribute and use additional
wastewater, thereby avoiding disposal thereof as a waste product and reducing the need
for additional water that otherwise must be delivered from Metropolitan’s imported water
supply system for landscape irrigation purposes;
-4-
MWD Agreement No.. 23300
Q. Carlsbad is currently planning and desires to construct additional capital facilities
collectively known as the Phase II Project, to treat and distribute, for beneficial use,
additional treated wastewater, which will minimize present and future disposal of
wastewater as a waste product from Carlsbad, in a manner cost-effective for its
customers;
R. Metropolitan, in accordance with its LRP, desires to assist Carlsbad in the cost of treating
and distributing recycled water for landscape irrigation purposes;
S. Carlsbad ,desires to comply with the provisions of Metropolitan’s LRP in return for
Metropolitan’s financial assistance for the Project;
T. Metropolitan desires to assist in increasing production and distribution of recycled water
by providing financial incentives to Carlsbad, through Authority, for implementation of
the Project.
U. Authority desires to participate in and affirmatively supports the Project by transferring to
Carlsbad the financial incentives that it receives from Metropolitan;
V. The Parties believe that treatment and distribution of recycled water from the Project will
benefit the local community within Carlsbad and the region served by Metropolitan;
W. The Project, when fully developed, is estimated as being capable of delivering 5,000 acre-
feet per year of recycled water by treating secondary wastewater and distributing recycled
water for landscape irrigation purposes.
NOW, THEREFORE, in consideration of the promises and covenants hereinafter set forth, the
Parties do agree as follows:
Section 1: Definitions
The following words and terms, unless otherwise expressly defined in their context, shall be

EXHIBIT A
The Encina Basin Water Reclamation Project - Phases I and II
Project Description
Overview:
The Encina Basin Water Reclamation Project - Phases I and II (Project) is owned and operated
by the Carlsbad Municipal Water District (Carlsbad). Under the Project, approximately 5,000
acre-feet per year (AFY) is delivered to Carlsbad Recycled Water customers for landscape,
agricultural, commercial and industrial purposes. The Project is located entirely within
Carlsbad’s service area immediately south of Palomar Airport Road and west of El Camino Real
(see Figure 1).
Sources of Recycled Water
1. Meadowlark Water Reclamation Facilily
Under Phase I, the Project currently receives Recycled Water from two external sources. The
majority of the Project’s water needs are supplied by the Meadowlark Water Reclamation
Facility (Meadowlark), which is owned and operated by Vallecitos Water District (Vallecitos).
Meadowlark provides primary, secondary and tertiary treatment to wastewater and has a current
capacity of about 2 million gallons per day. Recycled Water from Meadowlark is delivered to
the Project through Vallecitos’ fail-safe pipeline. Recycled Water in the fail-safe pipeline which
is not used by the Project is delivered to the Encina Water Pollution Control Facility (Encina)
and then discharged to the ocean. Carlsbad has entered into an agreement with Vallecitos to
purchase up to 2,040 AFY from Meadowlark. Meadowlark, the Mahr Reservoir and Vallecitos’
fail-safe pipeline are pre-existing and not part of the Project.
2. Gafier Water Reclamation Plant
The second source of Phase I Recycled Water is the Gafner Water Reclamation Plant (Gafner),
which is owned and operated by Leucadia County Water District (Leucadia). Gafner provides
primary, secondary and tertiary treatment and has a current capacity of about 0.75 million gallons
per day. Raw wastewater can also be sent to Encina via a separate pipeline from Gafner. At
Leucadia’s discretion, secondary treated wastewater can be pumped back from Encina to Gafner
for tertiary treatment. Carlsbad has entered into a take-or-pay agreement with Leucadia to
purchase a minimum of 394 AFY from Gafner for Recycled Water deliveries supplied only to La
Costa South Golf Course. Gafner and Encina are pre-existing and not part of the Project.
-12-
MWD Agreement No. 23300
3. Carlsbad Water Recycling Facility
I Included in the development of Phase II facilities is construction of the proposed 5 million
gallons per day Carlsbad Water Recycling Facility (CWRF). CWRF will provide tertiary
treatment of secondary effluent from Encina and serve Recycled Water to the Project. Additional
facilities may include microfiltration and reverse osmosis to reduce total dissolved solids levels
in Recycled Water.
Project Facilities
Phase I
Phase I of the Project consists of a distribution system, conversion of two potable water
reservoirs to Recycled Water reservoirs and installation of potable water pipelines to replace
pipelines for Recycled Water use. The distribution system includes about six miles of Recycled
Water pipeline, pumping facilities, and a one-mile pipeline to replace the existing potable water
pipeline that will be converted for Recycled Water use. Both the La Costa North and South Golf
Course receive Recycled Water from the Project via existing, non-project pipelines. In addition,
the Project includes capital improvements to Meadowlark including modifications to the effluent
pump station, construction of a diversion structure, and installation of electrical and
instrumentation equipment.
Phase II
-
Phase II of the Project will involve construction of the 5 million gallons per day CWRF,
extension of the existing Recycled Water distribution system by approximately 75,000 feet to
serve new users, construction of a new pump station, and conversion of the existing Mahr
Reservoir for Recycled Water storage. Although capital improvements to convert the existing
Mahr Reservoir from potable to Recycled Water use are included in the Project, the Mahr
Reservoir is considered pre-existing and not part of the Project.
End Users
Recycled Water from the Project will be produced for non-potable landscape and agricultural
irrigation, and commercial and industrial purposes within Carlsbad’s service area.
Points of Connection
Project facilities shall terminate at the points of connection to the Project’s sources of supply,
brine disposal facilities, Mahr Reservoir, the potable distribution systems, sewer systems, storm
drains, groundwater extraction systems, Vallecitos’ fail-safe pipeline, and meter connections to
End Users.

The Agreement will terminate if construction of Phase II facilities has not
commenced by April 1,2002. If this Agreement is terminated under this provision,
the Conversion Agreement shall be restored to full force and effect. There is no
established appeal process for this outcome.
The Agreement will terminate if Project production is not delivered from the
proposed 5 million gallons per day CWRF by April 1,2006. If this Agreement is
terminated under this provision, the Conversion Agreement shall be restored to full
force and effect. The Project sponsor(s) may appeal this decision to Metropolitan’s
Board of Directors.
If Phase II production from the CWRF during Fiscal Years 2004-05 through 2007-08
does not reach the target yield of 1,092 acre-feet (AF), Metropolitan will reduce the
Allowable Yield outlined in Exhibit B. The reduction shall be one-half the shortfall
between the targeted yield and the highest Phase II production in that period. For
example, the Phase II Ultimate Yield of the Project for the following performance
will be revised from 2,950 to 2,879 AFY for Scenario 1 beginning in Fiscal Year
2008-09. There would be no adjustment under Scenario 2.

The Department of Health Services has reviewed the "Mitigated
Negative Declaration" and "Notice of Completion" for the
Carlsbad Municipal Water District's "Encina 'Basin Water
Reclamation Program Phase II" project dated December 10, 1999,
and offer the following comments:
As stated in the subject document, the District is proposing
to construct a new water recycling plant, make improvements to
an existing treatment facility and reservoir site, and '
construct new pump stations and 10 miles of additional
transmission pipelines to deliver recycled 'water to various
use sites within their service area. The use of recycled
water is permitted by the California Regional Water Quality
Control Board and must be in accordance with the requirements
prescribed by the California Wastewater Reclamation Criteria
(Title 22). Title 22 requires the submittal of an engineering

RE: COMMENTS ON THE ENCfNA BASIN WATER RECLAMATION PROGRAM
PHASE II PROPOSED MITIGATED NEGATIVE DECLARATION
Dear Mr. Martin:
The Olivenhain Municipal Water District appreciates the opportunity to comment on the
City of Carlsbad’s proposed Mitigated Negative Declaration for the Encina Basin Water
Reclamation Program Phase II.
The District has concluded that the project will have significant, impacts on the
environment in several areas:
1)
2)
3)
4)
A substantial and significant exposure to contaminate a public water supply is
being created.
It wilt create a potential health hazard to people in the affected area.
dt will require substantial alteration to existing potable water utilities in the
effected area.
It will have significant impact on the quality of future public services outside the
city limits and within the City of Encinitas.
By way of background, the Olivenhain Municipal Water District is currently the potable
water purveyor in a portion of the region that will .be impacted by the project. A
substantial amount of infrastructure for the purpose of Serving recycled water has been
installed in the District’s service area.. This existing recycled infrastructure is currently
being served with potable water from the Olivenhain Municipal Water District’s system.
The City’s project irroutd transport recycled water into Olivenhain’s potable system

Mr. Jason Martin

is agreed upon by the City of Carisbad and the Olivenhain Municipal Water District to
integrate recycled water into the existing recycled infrastructure. Adequate changes in
the existing potable water system must be made to assure safe segregation of potable
and recycled water,
Presently. the City of Carlsbad and the Olivenhain Municipal Water District have three
agreements designating the Olivenhain Municipal Water District as the sole purveyor of
all potable water within its service jurisdiction (copies are provided for your
convenience). The City recognized the need for a single water purveyor by these
agreements as recycled water service was discussed during the negotiations for the
Hunt Brothers and Woolley annexations. introducing recycled water into Olivenhain’s
service area without adequate planning will create a significant environmental impact.
It is the District’s duty to insist that adequate planning, discussion and agreement for
mitigation of these impacts is conducted before the City of Carlsbad can adopt a
Mitigated Negative Declaration. It will be necessary to determine which agency will
maintain and operate the recycled system. It will be necessary to determine how
adequate coordination can take place to avoid cross connections and contamination of the potable water system in this area. it will be necessary to develop an emergency
response between both agencies to adequately respond to leaks and other emergency
failures of the system, as well as to respond to customer c:seds for service on a day to
day basis. It will be necessary to address the service needs of District customers
outside the City of Carlsbad. as the present project, as proposed, will eliminate the ability of other customers outside the city limits to receive recycled service in the future.
The District thoroughly appreciates the efforts of the City of Carlsbad to bring recycled
water service to this region. The Olivenhain Municipal Water District already has
recycled water service plans in areas being contemplated by the City of Carlsbad, as
well as an extensive program in its southeast service area. The District believes that
the best se&e to the region and its citizens can be accomplished by a coordinated
effort to adequately protect the health and safety of the community, as &elf as working
towards adequate supplies of all water.
The District requests that a 15day extension for the time to respond to the Mitigated
Negative Declaration be approved by the Planning Director, Michael J. Ho&miller. This
would allow ttie City and District staffs to sit down and discuss methods of achieving a Mitigated Negative Declaration for the City’s project to move fonnrard in a timely manner.
if an extension cannot be granted, the District believes that the Negative Declaration is
inadequate and has failed to address a number of significant environmental impacts as
numerated above.

David C. McCollom, General Manager
Olivenhain Municipal Water District
1966 Olivenhain Road
Encinitas, CA 92024
SUBJECT: RESPONSE TO COMMENTS ON THE ENCINA BASIN WATER
RECLAMATION PROGRAM, PHASE II PROJECT, MITIGATED
NEGATIVE DECLARATION
Dear David:
The City is resbonding to your letter dated January 13,2000, regarding
comments you submitted on the subject mitigated negative declaration. Your
letter contained several comments which are stated below followed by our
response.
COMMENT 1: The City’s project would transport recycled water into Olivenhain’s
potable system causing over 5,000 households to drink recycled water. This is
against State and Federal Laws. Significant health consequences will result,
unless a detailed, plan is agreed upon by the City of Carlsbad and the Olivenhain
Municipal Water District to integrate recycled water into the existing recycled
infrastructure. Adequate changes in the existing potable water system must be
made to assure safe segregation of potable and recycled water.
RESPONSE: The existing recycled water distribution mains noted above have
been designed and installed for the exclusive use of recycled water only.
Because recycled water has been unavailable up to this time, provisions were
made to temporarily supply potable water into the recycled water distribution
mains until recycled water becomes available. These provisions were jointly
approved by the City of Carlsbad, the Olivenhain Municipal Water District ,and
the County Health Department. The provisions include temporary connections to Olivenhain Municipal Water District’s potable water system at two locations. One
connection is located near the intersection of Calle Barcelona and Ranch0 Santa
Fe Road and is shown on Drawing 323-8, Sheet 10 of approved plans. At this
location a note was placed on the drawings stating the following:
2075 Las Palmas Dr. - Carlsbad, CA 92009-l 576 l (760) 438-l 161 l FAX (760) 431-5769 @ 20
“ 6-inch Temporary Potable Water Supply. When reclaimed water is
available; remove 6” PVC Pipe and 6” Flg. Gate Valve and MJ X Flg.
adapters. Install 6” Blind Flg. @ Each Tee.”
This note was placed on the plans so that when the work noted above is done by
the Olivenhain Municipal Water District, then the potable water system will no
longer be connected to the recycled water distribution pipeline, and no cross
connection can occur with this project.
The other location is near the intersection of Calle Acervo and Ranch0 Santa Fe
Road. See Drawing 342-6, Sheet 2. Again pieces of above ground pipe will be
removed and the potable water pipeline will be blind flanged by the Olivenhain
Municipal Water District. When this work is done the potable water system will no
longer be connected to the recycled water distribution system, and no cross
connection can occur with this project.
In summary provisions have been made to remove temporary connections to the
Olivenhain Municipal Water District’s potable water supply. These temporary
connections will be removed prior to the placement of recycled water in the
recycled water distribution system. in addition, a cross connection control
specialist in concert with the County Health Department will inspect the system
and perform cross connection tests prior to placement of recycled water into the
recycled water distribution pipelines. Coordination will also occur by the City to
have the Olivenhain Municipal Water District perform the needed pipeline and
valve removals that involve the temporary connections. With these actions
performed no recycled water will enter the Olivenhain Municipal Water District
potable water system, and no cross connections will occur. Similar activities
have been performed at other locations in the City by the Carlsbad Municipal
Water District in coordination with the County Health Department. The City
presently has a detailed procedure to follow in these cases and no cross
connections have ever occurred.
COMMENT NO. 2: Introducing recycled water into Olivenhain’s service area
without adequate planning will create a significant environmental impact.
RESPONSE: As noted previously, planning for the removal of the temporary
connections have been made. The plans were jointly approved by the City, the
County Health Department and Olivenhain Municipal Water District having two temporary connections. When recycled water is ready to be delivered, then the
temporary connections are to be removed and the Olivenhain Municipal Water
District’s potable pipelines blind flanged by the Olivenhain Municipal Water
District. In addition, cross connection control specialists will perform cross
connection tests prior to the placement of recycled water into the recycled water
distribution pipelines. All this work will be coordinated through the County Health
Department. Therefore, no impact will occur as a result of this project.
2l
COMMENT 3: It will be necessary to determine which agency will maintain and
operate the recycled system. It will be necessary to determine how adequate
coordination can take place to avoid cross connections and contamination of the
potable water system in this area. It will be necessary to develop an emergency
response between both agencies to adequately respond to leaks and other
emergency failures of the system, as well as to respond to customer needs for
service on a day to day basis. It will be necessary to address the service needs
of District customers outside the City of Carlsbad, as the present project, as
proposed, will eliminate the ability of other customers outside the city limits to
receive recycled service in the future.
RESPONSE: The City is very willing to discuss which agency will provide
operation and maintenance, and perform cross connection control and testing of
the Phase II recycled water system with the Olivenhain Municipal Water District.
This activity shall be accomplished during the design phase of the project.
Similarly, an emergency response plan can be completed during the design
phase.
The Phase II Project is part of the “City of Carlsbad Water Reclamation Master
Plan” adopted by the City Council in March, 1992. The master plan did not
include delivery of recycled water outside of the City limits. No comments were
submitted by OMWD during the development and approval of this master plan
requesting that service be extended to areas outside of the City.
The master plan is being implemented in five phases. Phase I is completed and
Phase II is scheduled to begin the design phase. In conformance with the master
plan, the Phase II project was designed to meet the demand for recycled water
only within Carlsbad. This was also described in the authorized BUREC “North
San Diego County Area Water Recycling Project”. The Phase II project will not
produce enough recycled water to meet additional irrigation demands outside of
Carlsbad. In addition, there would be additional expense to extend the system
beyond Carlsbad which may result in the project not being cost effective.
One concept being pursued is to connect the Phase II project system with the
recycled water system being developed by the San Elijo Joint Powers Agency.
This would provide an opportunity to obtain any excess supply of recycled water
from that agency into Carlsbad, and also any excess water not being used in
Carlsbad could be deliver?d to their system.
COMMENT 4: The District requests that a 15day extension for the time to
respond to the Mitigated Negative Declaration be approved by the Planning
Director, Michael J. Holtzmiller. This would allow the City and District staffs to sit
down and discuss methods of achieving a Mitigated Negative Declaration of the
City’s project to move forward in a timely manner. If an extension cannot be granted, the District believes that the Negative Declaration is inadequate and
22
. -
has failed to address a number of significant environmental impacts as
numerated above.
RESPONSE: The Planning Department received your written comments
regarding the proposed Mitigated Negative Declaration on January 13, 2000,
which was within the 30 day review and comment period. Since we did receive
your comments within the specified time period, the Planning Department did not
find it necessary to extend the review and comment period an additional 15
days.
It is possible that the intent of your request was to delay the public hearing date
where the Mitigated Negative Declaration would be considered by the City
Council. The item was initially, tentatively scheduled for consideration by the City
Council on January 18,200O. The item has been rescheduled for the January
25, 2000, meeting.
Sincerely,
Deputy City Engineer
