Impact Reports for both the Southeast Redevelopment Project and the Poseidon Project.
NOW, THEREFORE, the City Council of the City of Huntington Beach does hereby find,
order, determine, and resolve as follows:
SECTION 1. Consistent with CEQA Guidelines Section 15132, the Final EIR for the
Project is comprised of the Draft Recirculated EIR and Appendices, the comments received on the
Draft Recirculated EIR, the Responses to Comments, the Errata(bound together with the Responses
to Comments), the Appendices to the Responses to Comments and all Planning Department Staff
Reports to the City Council, including all minutes, transcripts, attachments, incorporation, and
references.
SECTION 2. The City Council makes the findings contained in the attached "Statement of
Facts and Findings" with respect to significant impacts identified in the Final EIR and finds that
each fact in support of the findings is true and is based upon substantial evidence in the record,
including the Final EIR. The Statement of Facts and Findings is attached as Exhibit "A" to this
Resolution and incorporated herein by this reference.
SECTION 3. The City Council finds that the Final EIR has identified all significant
environmental effects of the Project and that there are no known potential environmental impacts
not addressed in the Final EIR.
SECTION 4. The City Council finds that all significant effects of the Project are set forth
in the Statement of Findings and Facts and the Final EIR
SECTION 5. The City Council finds that although the Final EIR identifies certain
significant environmental effects that will result if the Project is approved, all significant effects
which can feasibly be mitigated or avoided have been mitigated or avoided by the incorporation of
Project design features, standard conditions and requirements, and by the imposition of mitigation
measures on the approved Project. All mitigation measures are included in the "Mitigation
Monitoring and Reporting Checklist" (also referred to as the "Mitigation Monitoring Program")
attached as Exhibit "B"to this Resolution and incorporated herein by this reference.

Res. No. 2005-62
SECTION 6. The City Council finds that the Final EIR has described reasonable
alternatives to the Project that could feasibly obtain the basic objectives of the Project(including the
"No Project" Alternative), even when these alternatives might impede the attainment of Project
objectives and might be more costly. Further, the City Council finds that a good faith effort was
made to incorporate suggested alternatives in the preparation of the Draft Recirculated EIR and that
a reasonable range of alternatives was considered in the review process of the Final EIR and
ultimate decisions on the Project.
SECTION 7. The City Council finds that no "substantial evidence" (as that term is defined
pursuant to CEQA Guidelines Section 15384) has been presented which would call into question
the facts and conclusions in the EIR.
SECTION 8. The City Council finds that no "significant new information" (as that term is
defined pursuant to CEQA Guidelines Section 15088.5) has been added to the Draft Recirculated
EIR since its distribution. The City Council finds that the refinements that have been made in the
Project do not amount to significant new information concerning the Project, nor has any significant
new information concerning the Project become known to the City Council through the public
hearings held on the Project, or through the comments on the Draft Recirculated EIR and Responses
to Comments.
SECTION 9. The City Council finds that the Mitigation Monitoring Program establishes a
mechanism and procedures for implementing and verifying the mitigations pursuant to Public
Resources Code 21081.6 and hereby adopts the Mitigation Monitoring Program. The mitigation
measures shall be incorporated into the Project prior to or concurrent with Project implementation.
SECTION 10. The City Council finds that the unavoidable significant adverse effects of the
Project as identified in Section 5.0 of the Statement of Facts and Findings (short-term construction
related impacts in regards to air quality) have been lessened in their severity by the application of
standard conditions, the inclusion of Project design features and the imposition of the mitigation
measures. The City Council finds that the remaining unavoidable significant impacts are clearly
outweighed by the economic, social, and other benefits of the Project, as set forth in the "Statement
of Overriding Considerations" included as Section 7.0 of the Statement of Facts and Findings. The
City Council adopts the recitation of overriding considerations which justify approval of the Project
notwithstanding certain unavoidable significant environmental effects which cannot feasibly be
substantially mitigated as set forth in the Statement of Overriding Considerations.
SECTION 11. The City Council finds and certifies that the Final EIR reflects the
independent review and judgment of the City of Huntington Beach City Council, that the Final EIR
was presented to the City Council, and that the City Council reviewed and considered the
information contained in the Final EIR prior to approving Conditional Use Permit No. 02-04 and
Coastal Development Permit No. 02-05.
SECTION 12. The City Council finds that the Final EIR serves as adequate and appropriate
environmental documentation for the Project. The City Council certifies that the Final EIR
prepared for the Project is complete, and that it has been prepared in compliance with the
requirements of the California Environmental Quality Act and CEQA Guidelines.

STATEMENT OF FACTS AND FINDINGS
AND STATEMENT OF OVERRIDING CONSIDERATIONS
1.0 INTRODUCTION
The California Environmental Quality Act ("CEQA") in Public Resources Code Section 21081
provides that:
"[N]o public agency shall approve or cant' out a project for which an environmental
impact report has been certified which identifies one or more significant effects on the
environment that would occur if the project is approved or carried out unless both of the
following occur:
(a) The public agency makes one or more of the following findings with respect to each
significant effect:
(1) Changes or alterations have been required in, or incorporated into, the
project which mitigate or avoid the significant effects on the environment.
(2) Those changes or alterations are within the responsibility and jurisdiction of
another public agency and have been, or can and should be, adopted by that
other agency.
(3) Specific economic, legal, social, technological, or other considerations,
including considerations for the provision of employment opportunities for
highly trained workers, make infeasible the mitigation measures or
alternatives identified in the environmental impact report.
(b) With respect to significant effects which were subject to a finding under paragraph (3)
of subdivision (a), the public agency finds that specific overriding economic, legal, social,
technological, or other benefits of the project outweigh the significant effects on the
environment.
The City of Huntington Beach certifies the Seawater Desalination Project at Huntington Beach
Environmental Impact Report ("EIR") and approves the following project components:
construction and operation of a seawater desalination facility, which includes an administration
building, a reverse osmosis facility building, a pretreatment filter structure, a chemical
storagelsolids handling building, a bulk chemical storage building, product water and influent
pump stations (situated underground) and surge tank, a rinse tank, a lime silos, a wash water
tank, carbon dioxide tanks, an ammonia tank, an electrical substation building, an aboveground
product water tank, appurtenant facilities, and pipelines and pump stations to deliver drinking
water into the regional water distribution system. Also part of the project includes the demolition
of three fuel storage tanks and interior berms, a conditional use permit ("CUP") and a Coastal
Development Permit ("CDP"). Due to the potential impacts to the environment and because the
proposed action constitutes a project under CEQA and the State CEQA Guidelines, the City of
Huntington Beach has prepared a Final Recirculated EIR (FREIR)(State Clearinghouse No.
2001051092). The FREIR identified certain potentially significant effects that may occur as a
City of Huntington Beach August 22, 2005
Page 1 of 47

Recirculated EIR No. 00-02
result of implementation of the project, unless mitigation measures, project design features
and/or standard conditions are adopted for the project. The mitigation measures, project design
features, and standard conditions identified in the FREIR are proposed to be adopted for the
project.
The DREIR was circulated for public review and comment for over a 45-day period (April 5,
2005 to May 27, 2005) as specified in the State CEQA Guidelines. Public comments were
received by the City and have been responded to by the City in accordance with CEQA
requirements.
The City of Huntington Beach determines that the Final EIR, comprised of the DREIR, a list of
persons, organizations and public agencies commenting on the DREIR, comments received
from the public and interested agencies, the Responses to Comments prepared by the City
(including Errata to the DREIR), and all attachments and documents incorporated by reference
is complete and adequate, and has been prepared in accordance with CEQA and the State
CEQA Guidelines.
The FREIR identified certain significant effects on the environment that may occur if the project
is approved or carried out. Therefore, in accordance with CEQA, the City of Huntington Beach
adopts this Statement of Facts and Findings and makes one or more of the three Section 21081
findings for each significant impact identified. For all but one of the significant effects identified
in the FREIR, changes or alterations have been required in, or incorporated into, the project that
mitigate or avoid the significant effects on the environment. In addition, for certain significant
effects that may occur, the Final EiR has identified changes or alterations that are within the
responsibility and jurisdiction of other public agencies. Those changes or alterations have been,
or can and should be, adopted by those other agencies.
The FREIR also identified one unavoidable significant effect on the environment that may occur
as a result of the project, even with the implementation of mitigation (see Section 5.0 of this
Statement of Facts and Findings). Where the decision of a public agency allows the occurrence
of a significant effect, which is identified in the FREIR but is not avoided, the agency must state
in writing the specific reasons to support its action based on the FREIR and other information in
the record. Such a statement is called a Statement of Overriding Considerations. In
accordance with CEQA, therefore, the City of Huntington Beach adopts the Statement of
Overriding Considerations included as Section 7.0 of this Statement of Facts and Findings.
This Statement of Facts and Findings, including the Statement of Overriding Considerations, is
adopted by the City of Huntington Beach as part of its action to certify the FREIR and approve
the Seawater Desalination Project at Huntington Beach.
2.0 DESCRIPTION OF PROJECT PROPOSED FOR APPROVAL
The proposed project involves the construction and operation of a seawater desalination facility
producing approximately 50 million gallons per day (mgd) of potable water. The facility would
take source water for the desalination facility from the existing condenser cooling seawater
discharge pipe system of the HBGS, purify it utilizing reverse osmosis (RO) technology,
discharge concentrated seawater byproduct water through the existing HBGS outfall, and
deliver potable product water to the distribution system.
The product drinking water will be delivered to the existing regional water distribution system to
meet the needs of Orange County. A more detailed project description is provided in Section
3.0, PROJECT DESCRIPTION of the DREIR.
City of Huntington Beach August 22, 2005

Recirculated EIR No.00-02
Off-site components necessary to effectuate delivery of the potable product water into the
existing regional water distribution system include a water transmission pipeline alignment
extending into the City of Costa Mesa and two booster pump stations (one within an
unincorporated portion of Orange County and another within the City of Irvine).
3.0 FINDINGS CONCERNING IMPACTS FOUND TO BE LESS THAN
SIGNIFICANT
In evaluating the potential impacts associated with the project, the FREIR identified potential
impacts that would not be significant. This section of the Statement of Facts and Findings
identifies those impacts that may occur with project implementation, but were found to be below
the threshold of significant. CEQA does not require findings for impacts that are found to be
less than significant, and therefore do not require mitigation. Nevertheless, the following
information is provided in order to summarize the bases for determinations of non-significance
for the potential impacts as presented in the Section 5.0, ENVIRONMENTAL ANALYSIS, in the
FREIR. (Note that Section 8.0, EFFECTS FOUND NOT TO BE SIGNIFICANT, provides an
examination of potential project impacts that were found not to be significant in the Initial Study.
That information is not repeated herein, but is incorporated by reference as if set forth in full in
this Statement of Facts and Findings.)
In some cases, the impacts addressed in this Statement of Facts and Findings are found not to
be significant due to their nature. In other cases, the determinations take into account certain
design features of the project. Although impacts determined to be not significant do not
themselves require mitigation, in some cases mitigation measures that have been required to
address other impacts found to be potentially significant and in need of mitigation will also
further reduce the non-significant impacts. In these cases, the mitigation measures are noted,
although the impacts would be less than significant even without such measures. Mitigation
measures are referenced in this Statement of Facts and Findings using the same numbering
system employed in the Mitigation Monitoring Program and the FREIR. Refer to Attachment B,
MITIGATION MONITORING PROGRAM for a complete listing of mitigation measures and
monitoring requirements.
A. IMPACTS RELATED TO LAND USE/RELEVANT PLANNING (DREIR page 5.1-1 to
5.1-11)
Section 5.1 of the DREIR addresses the potential impacts related to land use/relevant planning.
Both topics (land use and relevant planning) are addressed in this Section of the Statement of
Facts and Findings.
Finding for Potential Land Use Impacts
The Seawater Desalination Project at Huntington Beach will not create any significant impacts
to surrounding land uses. Less than significant impact. In addition, mitigation measures NOI-1,
ALG-1, ALG-2, and CON-1 through CON-47, inclusive, further reduce these less than significant
impacts.
Facts in Support of Finding
Based on the analysis presented in Section 5.1 of the DREIR, land use impacts are less than
significant without mitigation. Potential land use impacts have been eliminated or substantially
lessened to a level of less than significant by virtue of project design features identified in the
City of Huntington Beach August 22, 2005
Page 3 of 47
Seawater Uesaunation Project at Huntington beacn t-iNU1NUb Ur t-AU t 5
Recirculated EIR No.00-02
DREIR. Moreover, mitigation measures NOI-1, ALGA ALG-2, and CON-1 through CON-45,
inclusive, further reduce these less than significant impacts.
Finding for Potential Relevant Planning Impacts
The Seawater Desalination Project at Huntington Beach will not conflict with applicable relevant
planning programs. No impact.
Facts in Support of Finding
Based on the analysis presented in Section 5.1 of the DREIR, relevant planning impacts are not
significant. The project as described in Section 2.0 of this Statement of Facts and Findings will
be consistent with the City of Huntington Beach General Plan, Local Coastal Program, Zoning
and Subdivision Ordinance, and with the SCAG Regional Comprehensive Plan and Guide.
There is no need to change any General Plan or Zoning designations. During the design
development stage, the Applicant will be submitting more detailed plans reflecting code and
policy compliance with specific issues. The design will be required to comply with all applicable
standard development conditions.
B. IMPACTS RELATED TO GEOLOGY, SOILS, & SEISMICITY (DREIR pages 5.2-1 to
5.2-13)
Section 5.2 of the DREIR addresses the project's potential impacts related to geology, soils and
seismicity. The DREIR addresses six topics, two of which (topography and off-site pipelines
and underground pump stations) are addressed in this Section. The remaining four topics are
addressed in Section 4.0-13 of this Statement of Facts and Findings.
Finding for Topography
The Seawater Desalination Project at Huntington Beach will have no significant impact on the
natural topography of the project area. Less than significant impact.
Facts in Support of Finding
Based on the analysis presented in Section 5.2 of the DREIR, topography impacts are less than
significant without mitigation. No significant landform impacts will result because the project
area is relatively flat. The proposed desalination facility site consists of three fuel storage tanks
on a flat surface, surrounded by containment berms of 10 to 15 feet in height. The western and
southern berms would be removed prior to construction of the desalination facility, while the
eastern and northern berms (the northern berm exists outside of the project boundaries) will not
be removed. The site does not contain any unique physical or topographical features.
Finding for Off-Site Pipelines and Underground Pump Stations
The Seawater Desalination Project at Huntington Beach off-site pipelines and underground
pump stations will not subject to significant hazards related to geology, soils and seismicity.
Less than significant impact. In addition, applicable mitigation measures contained within
Section 5.9 of the DREIR, inclusive, further reduce these less than significant impacts.
City of Huntington Beach August 22, 2005
Page 4 of 47
beawater uesaitnation vroject at Huntington beacn t-INLANUb VI- t-AU!5
Recirculated EIR No.00-02
Facts in Support of Finding
Based on the analysis presented in Section 5.2 of the DREIR, impacts related to geology, soils
and seismicity for the project's off-site pipelines and pump stations are less than significant. No
significant impacts will result because the majority of the pipeline alignment will occur within
existing street right-of-way and various utility lines currently exist along the alignment. The
pump station locations are also located in close proximity to existing pipelines. Standard
conditions similar to those to be implemented for the on-site desalination facilities will apply to
minimize impacts and design level geotechnical investigations will be performed. Moreover,
applicable mitigation measures contained within Section 5.9 of the DREIR, inclusive, further
reduce these less than significant impacts.
C. IMPACTS RELATED TO HYDROLOGY, DRAINAGE AND STORM WATER RUNOFF
(DREIR pages 5.3-1 to 5.3-8)
Section 5.3 of the DREIR addresses the project's potential long-term impacts related to
hydrology and water quality. The DREIR addresses four topics, two of which are addressed in
this Section. The remaining topics are addressed in Section 4.0-C of this Statement of Facts
and Findings. The topics where the impacts were found to be less than significant are:
• Fertilizer and Pesticides
• Water Quality Impacts to Nearby Coastal Wetlands from On-site Spillage
Finding for Fertilizer and Pesticides
The use of fertilizers and pesticides on landscaping at the Seawater Desalination Project at
Huntington Beach will not have a significant impact on water quality. No significant impact is
found. In addition, mitigation measure HWQ-1 further reduces this less than significant impact.
Facts in Support of Finding
The project will incorporate both native and non-native landscaping on site, as explained in
Section 5.3 of the DREIR. Non-native vegetation may require periodic fertilization and pest
control. The use of fertilizers and pesticides would comply with the City of Huntington Beach
standards as well as the guidelines set forth in the Orange County Management Guidelines.
The landscaping will be maintained in accordance with City of Huntington Beach standards.
Based on the size of the landscaped areas, small amounts of fertilizers and pesticides will be
needed. Use of these chemicals on project landscaping will not result in a significant impact to
groundwater, adjacent Ocean waters, or surrounding uses. Moreover, mitigation measure
HWQ-9 further reduces this less than significant impact.
Finding for Potential Water Quality Impacts to Nearby Coastal Wetlands from On-Site
Spillage
Potential on-site spillage from the Seawater Desalination Project at Huntington Beach will have
no significant impact on nearby coastal wetlands. Less than significant impact.
Facts in Support of Finding
As explained in Section 5.3 of the DREIR, the project design incorporates appropriate leak/spill
containment features that minimize the likelihood for hazardous materials being stored, used or
transported on-site from impacting adjacent uses. Moreover, nearby coastal wetlands, including
City of Huntington Beach August 22, 2005

Recirculated EIR No.00-02
the privately owned open space/wetlands area that abuts the edge of the southwest corner of
the desalination facility site, are physically separated from the desalination facility by existing
berms (that will remain in place).
D. IMPACTS RELATED TO AIR QUALITY(DREIR pages 5.4-1 to 5.4-17)
Section 5.4 of the DREIR addresses the potential impacts related to air quality. Four topics
(long-term mobile source emissions and electricity consumption, chemical storage facilities, off-
site pipelines and underground pump stations, and consistency with regional plans) are
addressed in this Section of the Statement of Facts and Findings.
Finding for Mobile Source Emissions and Electricity Consumption
The Seawater Desalination Project at Huntington Beach will not result in significant impacts in
regards to mobile or off-site energy related air emissions. Less than significant impact.
Facts in Support of Finding
The analysis in Section 5.4 of the DREIR shows that the desalination facility would generate
nominal amounts of on-site area source and off-site mobile source emissions. In addition, off-
site energy emissions associated with the proposed facility's electricity consumption have been
previously accounted for within local and regional planning documents as well as environmental
documentation prepared for SCAQMD's Regional Clean Air Incentives Market (RECLAIM) and
New Source Review programs. Impacts in this regard are not anticipated to be significant.
Finding for Chemical Storage Facilities
The proposed project would not result in significant air quality impacts in regards to chemical
storage facilities. Less than significant impact.
Facts in Support of Finding
As explained in Section 5.4 of the DREIR, the proposed desalination plant would use fewer
chemicals of lower dosages than existing conventional water treatment plants in Southern
California. In addition, based on the types of chemicals stored on site and their containment
methods, odors are unlikely to emanate from the project site. Chemical storage and the use of
chemicals during the desalination process are not anticipated to have significant impacts to air
quality in the region.
Finding for Off-Site Pipelines and underground Pump Stations
The Seawater Desalination Project at Huntington Beach will not significantly impact air quality.
The impacts associated with the operation of diesel-power generators are anticipated to be less
than significant.
Facts in Support of Finding
It would be necessary to apply for a Special Application for Temporary Emergency Authorization
To Operate Electric Backup Generator(s) During Involuntary Power Service Interruptions
Permit.' The project would obtain all required air quality permits. Therefore, impacts associated

with the operation of diesel- powered generators are anticipated to be less than significant, as
explained in Section 5.4 of the DREIR. In addition, water transmission lines would not result in
criteria pollutant emissions and therefore would not have any significant impacts to air quality.
Finding for Consistency with Regional Plans
The Seawater Desalination Project at Huntington Beach will not conflict with local and regional
air quality planning documents. Less than significant impact.
Facts in Support of Finding
As explained in Section 5.1 of the DREIR, the proposed project does not involve a General Plan
amendment, zone change, or other change in land use, and is consistent with the County of
Orange and City of Huntington Beach land use assumptions. The regional Air Quality
Management Plan (AQMP) is based on the City and County's General Plan assumptions, and
the project is consistent with these assumptions. Consequently, as explained in Section 5.4 of
the DREIR, the project would be considered consistent with the AQMP. In addition, according
to SCAG, the project is consistent with the Regional Comprehensive Plan and Guide (RCPG).
Impacts in this regard are not anticipated to be significant.DR
E. IMPACTS RELATED TO NOISE (DREIR pages 5.5-1 to 5.5-13)
Section 5.5 of the DREIR addresses the project's potential impacts related to noise. The
DREIR addresses two topics (mobile noise sources and stationary noise sources). Mobile noise
sources and stationary noise sources for the off-site pipelines and booster pump stations are
addressed in this Section. Stationary noise sources for the desalination facility site are
addressed in Section 4.0-E of this Statement of Facts and Findings.
Finding for Mobile Noise Sources
The Seawater Desalination Project at Huntington Beach will not generate a significant amount
of noise resulting from mobile noise sources. Less than significant impact.
Facts in Support of Finding
As explained in Section 5.5 of the DREIR, the project would generate a nominal amount of
noise resulting from mobile sources as a result of employee trips and truck-generated traffic.
The proposed desalination facility would employ a total of approximately 18 people, with an
average of five to seven people on-site per shift on weekdays. In addition, facility operation
would require a maximum of four truck trips per day for solid waste disposal and chemical
delivery. Noise generated by mobile sources as a result of the proposed desalination facility is
so nominal that impacts in this regard will be less than significant.
Findingfor Noise from Long-Term Operations of Off-Site Pipelines and Underground

Page 7 of 47
seawater Uesaiination vroject at runtington tseacn t-INUINUZ5 OF t-At;s s
Recirculated EIR No.00-02
Facts in Support of Finding
As explained in Section 5.5 of the DREIR, the proposed product water pipelines would occur
entirely underground. Upon completion of construction, these pipelines would not generate
noise. In addition, as the OC-44 booster pump station would be placed underground, the off-
site underground booster pump station is not anticipated to adversely affect the NCCP/HCP
area along the eastern border of the City of Newport Beach. Similarly, the coastal junction
booster pump station would both be located underground and contain an adequate amount of
acoustical shielding. Impacts in this regard are not anticipated to be significant.
F. IMPACTS RELATED TO PUBLIC SERVICES AND UTILITIES (DREIR pages 5.6-1 to
5.6-14)
Section 5.6 of the DREIR addresses the project's potential impacts related to public services
and utilities. The DREIR addresses fourteen topics, eight of which are addressed in this
Section. The remaining topics are addressed in Section 4.0-F of this Statement of Facts and
Findings. The topics where the impacts were found to be less than significant are:
• Fire Service
• Police Service
• Libraries
• Parks and Recreation
• Reclaimed Water
• Electricity
• Gas
• Telephone and Cable
Finding for Fire Service
The Seawater Desalination Project at Huntington Beach will not have a significant impact on the
demand for fire service within the City of Huntington Beach. Less than significant impact.
Facts in Support of Finding
It is not anticipated that project implementation would result in the need for additional Fire
Department facilities. The project is not of the scope or nature to create a significant increase in
demand for services requiring physical additions to the City of Huntington Beach Fire
Department. As explained in Section 5.6 of the DREIR, impacts are less than significant.
Finding for Police Service
The Seawater Desalination Project at Huntington Beach will not have a significant impact on the
demand for police service within the City of Huntington Beach. Less than significant impact.
Facts in Support of Finding
Implementation of the project will not create a significant increase in service calls to the project
area nor is it expected to result in the need for additional police facilities within the City of
Huntington Beach. As explained in Section 5.6 of the DREIR, impacts are less than significant.

Finding for Libraries
The Seawater Desalination Project at Huntington Beach will not have a significant impact on the
City of Huntington Beach library system. Less than significant impact.
Facts in Support of Finding
The proposed desalination project is not anticipated to have significant impacts on the City of
Huntington Beach library system. Although the nearest library facility to the project site (the
Banning Branch Library) is small in size, the project is anticipated to have a negligible impact on
the branch. The applicant will be required to pay standard library enrichment fees concurrent
with building permit issuance. As explained in Section 5.6 of the DREIR, impacts are less than
significant.
Finding for Parks and Recreation
The Seawater Desalination Project at Huntington Beach will not have a significant impact on the
demand for parks and recreational facilities within the City of Huntington Beach. Less than
significant impact.
Facts in Support of Finding
The desalination plant will employ approximately 18 people, with five to seven people on duty
during regular working hours Monday through Friday, and a minimum of two people on duty
during swing shifts, graveyard shifts, and weekends. Consequently, the project is anticipated to
have a negligible impact on parks and recreation facilities within the City of Huntington Beach.
As explained in Section 5.6 of the DREIR, impacts are less than significant.
Finding for Reclaimed Water
The Seawater Desalination Project at Huntington Beach will not have a significant impact on the
availability of the City's reclaimed water facilities. Less than significant impact.
Facts in Support of Finding
The proposed project will not require the use of reclaimed water or installation of reclaimed
water facilities, as the project itself will be a new water reclamation source. As explained in
Section 5.6 of the DREIR, impacts are less than significant.
Finding for Electricity
The Seawater Desalination Project at Huntington Beach will not have a significant impact on the
electrical facilities providing service to the project vicinity. Less than significant impact.
Facts in Support of Finding
The project would consume approximately 720 to 840 megawatt hours per day. The facility may
utilize off-peak power to the maximum extent practicable. Electric power generating plants are
distributed throughout the state, and the project's electrical demand would be met by dozens of
power plants connected to a regional power supply source, with many of those plants located
outside of Southern California. SCE is prepared to install electrical distribution facilities to the
project site. As explained in Section 5.6 of the DREIR, impacts are less than significant.

Finding for Gas
The Seawater Desalination Project at Huntington Beach will not have a significant impact on
local natural gas facilities. Less than significant impact.
Facts in Support of Finding
The Southern California Gas Company can provide gas service to the proposed project via
numerous gas mains surrounding the subject site. Project implementation would not result in
any construction related impacts to the service area. As explained in Section 5.6 of the DREIR,
impacts are less than significant.
Finding for Telephone and Cable
The Seawater Desalination Project at Huntington Beach will not have a significant impact on
telephone or cable service facilities within the vicinity of the project area. Less than significant
impact.
Facts in Support of Finding
Both Verizon (telephone) and Time Warner (cable) will be available to provide service to the
subject site from existing facilities surrounding the subject site. As explained in Section 5.6 of
the DREIR, impacts are less than significant.
G. IMPACTS RELATED TO AESTHETICS/ LIGHT AND GLARE (DREIR pages 5.7-1 to
5.7-7)
Section 5.7 of the DREIR addresses the project's potential impacts related to aesthetics/light
and glare. The DREIR addresses three topics, one of which (off-site light and glare) is
addressed in this Section. The remaining two topics are addressed in Section 4.0-G of this
Statement of Facts and Findings.
Finding for Off-Site Light and Glare
The Seawater Desalination Project at Huntington Beach will not have a significant off-site light
and glare impact. Less than significant impact.
Facts in Support of Finding
As explained in Section 5.7 of the DREIR, off-site light and glare impacts are less than
significant. Project implementation may result in an insignificant increase in the amount of light
and glare off-site from vehicles utilizing the facility. However, additional lighting or glare-
inducing surfaces will not occur as a result of the water transmission pipeline or underground
pump stations because those facilities will be underground. Impacts in this regard are less than
significant.
H. IMPACTS RELATED TO HAZARDS AND HAZARDOUS MATERIALS (DREIR pages
5.8-1 to 5.8-10)
Section 5.8 of the DREIR addresses the potential impacts related to hazards and hazardous
materials.

Finding for Hazards and Hazardous Materials
The Seawater Desalination Project at Huntington Beach will not result in significant impacts in
regards to on-site hazards or hazardous materials. Less than significant impact.
Facts in Support of Finding
While potential future uses may require the storage, use, transportation, and/or handling of
hazardous materials, as explained in Section 5.8 of the DREIR, any such hazards would be
minimized by adherence to Federal, State, and City regulations. These requirements include
monitoring devices, spill control, emergency response plans, appropriate on-site safety
equipment, and the proper design of all facilities. With the implementation of standard
conditions and required design features, impacts in this regard will be less than significant.
Finding for Off-Site Pipeline Alignments and Underground Booster Pump Stations
The proposed desalination project would not result in long-term operational impacts in regards
to off-site pipeline alignments and underground booster pump stations. Less than significant
impact.
Facts in Support of Finding
As explained in Section 5.8 of the DREIR, the proposed off-site pipeline alignments would occur
adjacent to a variety of land uses. Hazardous materials impacts due to long-term operation of
the pipelines are not anticipated to occur, as the only liquid proposed for conveyance is potable
water. The OC-44 pump station and coastal junction pump station would both require a diesel
storage tank that would be placed underground and adequate safety measures would be
implemented. Impacts in regards to the off-site use, storage, and transport of hazardous
materials are not anticipated to be significant.
I. IMPACTS RELATED N D 9- -ATE TO CONSTRUCTION (DREIR pages 5. 1 to 5.9 36)
Section 5.9 of the DREIR addresses the p impacts potential im acts related to construction. All
p
of which are addressed in Section 4.0-1 and Section 5.0 of this Statement of Facts and Findings.
J. IMPACTS RELATED TO OCEAN WATER QUALITY AND MARINE BIOLOGICAL
RESOURCES (DREIR pages 5.10-1 to 5.10-41)
Section 5.10 of the DREIR addresses the project's potential impacts related to ocean water
quality and marine biological resources. Red Tides and Algal Toxins is addressed below, in
Section 4.0-K, Impacts Related to Product Water Quality. The topics where the impacts were
found to be less than significant are:
• Potential Sources of Contamination in Proximity to the HBGS Intake
• Elevated Bacteria Levels in the Huntington Beach Surf Zone
• Concentrated Seawater Discharge
• Reverse Osmosis Membrane Cleaning Solution
• Impingement and Entrainment

Recirculated EIR No.00-02
Finding for Potential Sources of Contamination in Proximity to the HBGS Intake
The Seawater Desalination Project at Huntington Beach will not be significantly impacted by
Orange County Sanitation District (OCSD) wastewater discharge, urban storm water runoff, dry
weather runoff, the recirculation of HBGS discharge, the Los Angeles and San Gabriel Rivers,
cruise ships and fishing boats, recreation, oil and gas production facilities, the operation of
HBGS, or elevated bacteria levels in the Huntington Beach surf zone. Less than significant
impact on the HBGS seawater intake.
Facts in Support of Finding
Oceanographers from the Scripps Institution of Oceanography conducted modeling studies
using a computer model that simulates ocean conditions near the HBGS intake and outfall (refer
to Appendix C, HYDRODYNAMIC MODELING REPORT of the DREIR). The modelers from
Scripps used their many years of experience working along the Southern California coast to
determine the worst case conditions that would be modeled. The worst case conditions were
chosen to determine if any adverse water quality or environmental impacts occurred under
extreme ocean and weather conditions that were most likely to show an effect. The analysis in
Section 5.10 of the DREIR shows that there will be a less than significant impact on the HBGS
intake from potential contamination sources.
Impact from OCSD Wastewater Discharge:
The worst-case model results show that the OCSD discharge is diluted 30 million to one at the
HBGS intake. Any contaminants discharged at the OCSD outfall would be diluted far below
background levels at the intake to the HBGS. Therefore, the OCSD discharge does not have a
significant source of contamination at the HBGS intake. As far as other constituents of concern
for the OCSD discharge, the desalination facility discharge water quality would be well within the
limits established in the Ocean Plan. Impacts in this regard will be less than significant.
Impact from Urban Storm Water Runoff.
During a 24-hour extreme runoff period only 0.0003 percent of the water at the HBGS intake
would come from the Santa Ana River and Talbert Marsh and the remaining 99.9997 percent
would be seawater. These results show that contaminants are not transported to the HBGS
intake from the Santa Ana River and Talbert Marsh during extreme storm conditions. More
detailed modeling results are presented in Appendix C of the DREIR, HYDRODYNAMIC
MODELING REPORT. impacts will be less than significant in this regard.
Impact from Dry Weather Runoff-
Tidal flushing of the Talbert Marsh would have the greatest potential to impact water quality at
the HBGS intake during high spring tides combined with summer El Nino conditions when
currents are flowing northwest from the marsh towards the intake. Under these worst-case
conditions, the marsh water is diluted 20,000 to one and essentially does not reach the intake.
This is due to the fact that the marsh water is released into the surf zone and the onshore
waves keep the marsh water in the shallow nearshore waters, whereas the HBGS intake is
located 1,840 feet offshore at a depth of approximately 33 feet. Impacts will be less than
significant.
Impact from the Recirculation of HBGS Discharge:
The HBGS outfall is located approximately 1,500 feet offshore and 340 feet from the HBGS
intake. The potential for recirculation of the discharge into the intake was examined. The
discharge consists primarily of cooling water, but a small amount of power plant process
City of Huntington Beach August 22, 2005
Page 12 of 47
Seawater uesaiination vrolect at runtington tseacn t-1NuM36 VF- t-AU i 5
Recirculated EIR No.00-02
wastewater and storm water can be mixed with the cooling water. The concentrated seawater
from the proposed desalination facility will also be mixed with the power plant cooling water.
Recirculation of the HBGS discharge would have the greatest potential to impact water quality
at the intake during El Nino storm conditions when the maximum amount of storm water is being
discharged through the outfall. The hydrodynamic model for recirculation of the HBGS
discharge was run using the El Nino conditions of February 1998 and the maximum allowable
discharge of 1.66 MGD of generating station process wastewater and storm water. In addition,
the proposed desalination facility was assumed to be running at full capacity so that 50 MGD of
concentrated seawater discharge was mixed with the cooling water discharge. Furthermore,
recirculation potential was examined under two generating scenarios: 1) one generating unit on-
line with a total discharge of 78.4 MGD of cooling water, storm water, and wastewater, and the
concentrated seawater discharge and 2) four generating units on-line producing a total
discharge of 458.6 MGD of cooling water, storm water, and wastewater, and the concentrated
seawater discharge. The model results under worst case conditions for a 7-day extreme runoff
period show that only 0.3 percent of the HBGS discharge would be recirculated to the intake.
The results for four generating units show a greater dilution with only 0.1 percent of the HBGS
discharge recirculated to the intake. Based on these results, the recirculation of the HBGS
discharge during storm events has been shown to not affect the source water quality at the
HBGS intake. Impacts are less than significant in this regard.
Impacts from the Los Angeles and San Gabriel Rivers:
The Los Angeles River discharges to the ocean approximately 16 miles upcoast (i.e. northwest)
from HBGS, while the San Gabriel River discharges approximately 11 miles upcoast. The
amount of dilution that occurs and the fact that the generating station intake is at a depth of
approximately 33 feet indicates that contaminants entering the ocean from these two rivers
would not likely affect the water quality at the HBGS intake. Impacts in this regard are less than
significant.
Impacts from Cruise Ships and Shipping Boats:
The nearest major port for cruise ships is located approximately 16 miles northwest of the
HBGS intake. Ingress/egress routes for cruise ships for Long Beach and Los Angeles Harbors
do not come in close proximity to the HBGS. In addition, given the limited nature of sportfishing
that occurs in the project site vicinity, impacts are less than significant.
Impacts from Recreation:
Any contaminants released into the ocean due to recreational use are likely to be small in
quantity greatly diluted due to tidal action. It would be difficult for such contaminants to reach
the HBGS intake due to its depth of approximately 33 feet below the ocean surface. Impacts in
regards to recreational uses are not anticipated to be significant.
Impacts from Oil and Gas Production Facilities:
There are two offshore oil platforms approximately 1.5 miles west of the HBGS intake and four
platforms approximately 10 miles west of the intake. There have not been any reportable spills
or leaks from the offshore oil platforms or the pipelines. A catastrophic event at one of the
offshore platforms that is near the coast could affect water quality at the HBGS intake.
However, given the relatively low probability based on operational history, impacts in this regard
are less than significant.
Impacts from Operations at HBGS:
There are numerous water quality constituents regulated in drinking water supplies. Samples
were collected from the HBGS intake vault and from the outlet of the condensers (where the
City of Huntington Beach August 22, 2005
Page 13 of 47
Seawater uesaunation vroject at nuntington tseacn HNusNU5 ur- VAU 15
Recirculated EIR No.00-02
desalination facility intake will be located). Although maximum contaminant levels (MCLs) apply
to treated drinking water, raw water concentrations that exceed MCLs provide an indication of
potential contaminants of concern. None of the primary MCLs are exceeded in the intake water
and the only secondary MCLs that are exceeded are salts (TDS, chloride, sulfate) that would be
removed by the reverse osmosis process. Impacts are less than significant in this regard.
Cycle water is discharged to the cooling water system at various locations as the cooling water
flows through the generating station. The cycle water is under vacuum so the cooling water
leaks into the cycle water but the cycle water does not leak into the cooling water. There are
several locations where cycle water is discharged into the cooling water system. The
contaminants in these discharges will be greatly diluted by the large volume of cooling water
compared to the small volume of the discharges. The only chemical of concern in a drinking
water source is nitrite. The other chemicals in the discharges are not toxic to humans and
drinking water standards have not been established. Because the volume of cooling water
represents a maximum of 0.002 percent of the cooling water flowing through one unit at the
HBGS, the nitrite concentration of 800 mg/L will be diluted to about 0.02 mg/L in the cooling
water that would reach the desalination facility. This level of nitrite is well below the drinking
water MCL of one mg/L. Nitrite and the other chemicals present in the cycle water discharges
will easily be removed by the reverse osmosis membranes. As a result, impacts in this regard
are less than significant.
Storm runoff from the HBGS site and a limited amount of off-site urban runoff is currently
discharged to the cooling water system upstream of the intake to the desalination facility. The
applicant would coordinate with HBGS to reroute these discharges during construction of the
desalination facility so they would be downstream of the desalination intake and not affect water
quality at the desalination intake. The off-site urban runoff is from approximately 70 acres of
land near the HBGS. Dry weather runoff collects in a ditch alongside Newland Street and is
currently pumped into the HBGS outfall pipeline. The City of Huntington Beach plans to modify
the system so that it flows into the HBGS site by gravity when improvements are made to
Newland Street as part of the conditions placed upon the project by the City of Huntington
Beach. Impacts are less than significant in this regard.
Low volume wastes, metal cleaning wastes, and pipeline hydrostatic test water are diverted to
the HBGS retention basin and then to the outfall, where the wastewater is mixed with cooling
water. Currently this waste is discharged downstream of the intake to the desalination facility
and would not be included in the source water for the proposed desalination facility. As a
result, impacts in this regard are not anticipated to be significant.
A number of petroleum products and other hazardous materials are stored and used at the
generating station. Although unlikely due to spill prevention measures and clean-up procedures
in place at the HBGS, there is the potential for a spill to reach the floor drain or the storm
drainage system and enter the cooling water system. The floor and yard drainage system
currently enters the outfall line downstream of the point where the desalination facility will be
located and would not be included in the desalination facility's source water. As a result,
impacts in this regard are not anticipated to be significant.
Periodically water from the discharge vault is diverted back into the facility and reheated. This
reheated water is then used to clean the discharge line of biological growths ("bio film"). This
recirculated water contains wastes that have been discharged to the discharge vault prior to the
flow being reversed in the facility. The proposed desalination facility would not intake water
from the HBGS cooling water system during heat treatments. In this regard, impacts are less
than significant.

Recirculated E1R No.00-02
Impacts from Elevated Bacteria Levels in the Huntington Beach Surf Zone:
Contaminants are not transported to the HBGS intake from the Santa Ana River and Talbert
Marsh during extreme storm event conditions. In addition, dry weather urban runoff at Talbert
Marsh during tidal flushing essentially does not reach the HBGS intake. Although the cause of
the elevated bacteria levels in the Huntington Beach surf zone has not been determined, the
seawater desalination process would have the ability to remove bacteria and produce potable
water meeting all State Title 22 standards. Impacts in this regard are less than significant.
Finding for Elevated Bacterial Levels in the Huntington Beach Surf Zone
The Seawater Desalination Project at Huntington Beach will not contribute to elevated bacterial
levels in the Huntington Beach Surf Zone. Less than significant impact.
Facts in Support of Finding
The modelers from Scripps used their many years of experience working along the Southern
California coast to determine the worst case conditions that would be modeled, as explained in
Section 5.10 of the DREIR. The worst case conditions were chosen to determine if any adverse
water quality or environmental impacts occurred under extreme ocean and weather conditions
that were most likely to show an effect. The effect of the Santa Ana River and Talbert Marsh
storm water on water quality at the HBGS intake was modeled assuming a very large,
prolonged storm event and ocean currents flowing from the mouth of the river towards the
HBGS facility. Normally, ocean currents flow in the opposite direction, down the coast
(southeast) away from the HBGS.
Extensive bacterial studies have shown that the Santa Ana River and Talbert Marsh appear to
be the primary sources of fecal indicator bacteria to the near shore ocean. In addition, bird
droppings and a reservoir of bacteria stored in the sediment and on marine vegetation may
continue to be the source of bacteria at the mouths of the river and marsh. Modeling studies
and monitoring data indicate that there is likely another unidentified source of bacteria in the
vicinity of Stations 6N and 9N. However, three separate studies conducted between 2001 and
2002 have demonstrated that HBGS is not the source of bacteria in the surf zone. Less than
significant impact on the Huntington Beach surf zone is expected.
Finding for Concentrated Seawater Discharge
The proposed desalination project concentrated seawater discharge will not significantly impact
ocean water quality or marine biological resources in the area. Less than significant impact.
Facts in Support of Finding
As explained in Section 5.10 of the DREIR, the proposed project's discharge would not have a
significant effect on organisms living around the discharge or organisms that would pass
through the area. Most of the marine organisms living near the HBGS also occur in other areas
of the Southern California Bight where naturally occurring salinities can be higher than what is
anticipated at the HBGS outfall. Plankton, fishes, and other water-column species would have
brief exposure to the concentrated seawater discharge field, and the area of benthic impacts
would be relatively small and localized. In addition, no endangered species or kelp beds exist
within the vicinity of the HBGS outfall. As ocean water quality impacts and impacts to marine
biological resources are not anticipated to be significant, a separate routine monitoring process
is not proposed as part of the project. However, if applicable, ocean water quality and biological
City of Huntington Beach August 22, 2005

seawater uesaiinavon Project at Huntington beacn VINuiNUZ5 Ur VAU 1,6
Recirculated EIR No.00-02
monitoring during long-term project operation will be conducted as directed by the RWQCB.
Impacts are less than significant in this regard.
Finding for Reverse Osmosis Membrane Cleaning Solution
The Seawater Desalination Project at Huntington Beach will not significantly impact ocean water
quality or marine biological resources due to the discharge of reverse osmosis membrane
cleaning solution through the HBGS outfall. Less than significant impact.
Facts in Support of Finding
As stated in the DREIR in Section 3.0, PROJECT DESCRIPTION, the reverse osmosis system
trains will be cleaned using a combination of cleaning chemicals such as industrial soaps (e.g.
sodium dodecylbenzene, which is frequently used in commercially available soaps and
toothpaste) and weak solutions of acids and sodium hydroxide. The "first rinse" treated waste
cleaning solution from the washwater tank will be discharged into the local sanitary sewer for
further treatment at the OCSD regional wastewater treatment facility. The cleaning rinse water
following the "first rinse" will be mixed with the RO facility concentrated seawater, treated waste
filter backwash, and the AES plant discharge and sent to the ocean. This "second rinse" water
stream will contain trace amounts of cleaning compounds and would be below detection limits
for hazardous waste. An Industrial Source Control Permit from the OCSD for discharge of
waste cleaning solution into the sanitary sewer system will be required for the project. In
addition, the discharge must comply with the limits and requirements contained in the OCSD's
Wastewater Discharge Regulations. The analysis in Section 5.10 of the DREIR shows that
impacts to the local marine environment would be less than significant.
As explained in Section 5.10 of the DREIR, an alternative to discharging the "first rinse" of the
RO membrane cleaning solution into the OCSD system is to discharge the solution ("first rinse"
and all subsequent rinses) into the Pacific Ocean via the HBGS outfall. The majority of the
chemicals within the membrane cleaning solution would be either below detection levels or
regulatory limits, even before dilution with other desalination facility and HBGS discharges.
Dilution at a 260 to one ratio would further minimize impacts to the marine environment and
would assure NPDES compliance. Impacts to the local marine environment would be less than
significant.
Finding for Impingement and Entrainment
The proposed desalination facility will have less than significant impacts on marine biological
resources in regards to impingement and entrainment effects. Less than significant impact.
Facts in Support of Finding
As explained in Section 5.10 of the DREIR, the proposed project source water intake would not
increase the volume, or the velocity of the HBGS cooling water intake nor would it increase the
number of organisms entrained or impinged by the HBGS cooling water intake system.
Therefore, the impingement and entrainment effects of the HBGS are not included in assessing
the proposed project's effects, as these organisms would not be exposed to further screening
prior to entering the desalination facility's pretreatment system.
The proposed desalination facility would not have a separate direct ocean water intake and
screening facilities, and would only use cooling water that is already screened by HBGS's
intake. In response to City Council direction to specifically look at the desalination project's
City of Huntington Beach August 22, 2005
Page 16 of 47
Seawater uesaunation vroiect at runtington tseacn HNuiNUS Ur t-AU i 5
Recirculated EiR No.00-02
potential impacts on impingement and entrainment, an intake Effects Assessment was
completed and incorporated in the REIR as Appendix T and discussed in Section 5.10, Ocean
Water Quality and Marine Biological Resources. The study was designed to investigate the
potential for the desalination project feed water intake withdrawn from the HBGS cooling water
system to increase the HBGS entrainment mortality and assess the significance of this potential
entrainment effect on the source water. The study concludes that the desalination project will
not cause any additional impingement losses to the marine organisms impinged by HBGS.
The study also determined, based on in-plant testing, that HBGS has an observed entrainment
mortality of 94.1 percent. The desalination project is estimated to increase mortality by 1.2
percent (from 94.1% to 95.3%) at flows of 507 MGD and by 4.6 percent (from 94.1% to 98.7%)
at flows of 127 MGD. Therefore, the estimated larval fish loss attributed to the proposed
desalination project would be 0.02 percent of the total population of larvae in the local area
surrounding the HBGS intake. In comparison, at the minimum cooling water intake flow of 127
MGD and assuming 100 percent mortality, HBGS has an entrainment loss of 0.33 percent.
The REIR notes that the most frequently entrained species are very abundant in the area of the
HBGS intake and the Southern California Bight, and therefore, the actual ecological effects due
to any additional entrainment from the desalination project are insignificant. Six taxa (gobies,
blennies, croakers, northern anchovy, ganbaldi and silversides) and a group of larvae that could
not be identified were found to comprise 97 percent of all the fish larvae present in the HBGS
cooling water system from which the proposed project would withdraw its source water supply.
Species of direct recreational and commercial value constitute a very small fraction of the
entrained organisms in the HBGS offshore intake.
Impacts due to operation of the proposed desalination facility in regards to impingement and
entrainment are less than significant.
K. IMPACTS RELATED TO PRODUCT WATER QUALITY (DREIR pages 5.11-1 to 5.11-
24)
Section 5.11 of the DREIR addresses the project's potential impacts related to product water
quality which are addressed below, in Section 4.0-K of this Statement of Facts and Findings.
L. CUMULATIVE IMPACTS
Section 6.3 of the DREIR addresses the project's potential cumulative impacts. The topics
where the impacts were found to be less than significant are:
• Local Cumulative Impacts
• Regional Cumulative Impacts
Finding for Potential Local Cumulative Impacts
The Seawater Desalination Project at Huntington Beach will not result in significant local
cumulative impacts. Less than significant impact.
Facts in Support of Finding
Section 6.3 of the DREIR addresses the cumulative impacts associated with the Seawater
Desalination Project at Huntington Beach. The cumulative impact analysis was based primarily
on build-out of the City's General Plan, Zoning and Subdivision Ordinance, and General Plan
City of Huntington Beach August 22, 2005
Page 17 of 47
,seawater uesalination rrolect at Huntington beacn t INuwU,s tit- t-AU i,s
Recirculated EIR No.00-02
EIR. The analysis also identified, listed and considered the potential cumulative impacts
resulting from the currently known probable projects at the time of DREIR publication. Section
6.3 of the DREIR specifically analyzed potential cumulative impacts in the areas of land
use/relevant planning, geology and soils, hydrology and water quality, air quality, noise, public
services and utilities, aesthetics/light and glare, hazards and hazardous materials, construction
related, biological resources (terrestrial only), and product water quality impacts. No significant
cumulative impacts were identified.
Finding for Potential Regional Cumulative Impacts
The Seawater Desalination Project at Huntington Beach will not result in significant regional
cumulative impacts. Less than significant impact.
Facts in Support of Finding
The DREIR notes in Section 6.3, that additional seawater desalination facilities were being
considered by various cities and agencies along the Southern California coast. Because those
projects are in various stages of conceptual consideration, and construction has not begun, the
Final REiR does not attempt to quantify or evaluate potential cumulative impacts of all of those
projects. Such an analysis is speculative at best, and is not required under CEQA Guidelines,
Section 15130[b]. However, an analysis is provided for certain proposed desalination facilities
along the Southern California coast (see Table 6-4). The Final REIR notes that the project,
together with these other proposed desalination projects, may facilitate new development in
south Orange County or elsewhere. Potential growth-inducing cumulative impacts, further
discussed below in Section 3.0-M of the Statement of Facts and Finding and explained in
Section 6.2 of the DREIR, are considered less than significant. All potentially significant impacts
to long-term water quality and marine biological sources would be reduced to less than
significant levels, as explained in Section 6.3 of the DREIR, through regulatory compliance, and
project design features and implementation of the recommended mitigation measures. Potential
cumulative impacts upon ocean water quality and marine biological resources are considered
less than significant. The impact of the additional electric energy demand by the proposed
project is less than one percent in Southern California and is therefore, less than significant.
M. GROWTH-INDUCING IMPACTS
Section 6.2 of the DREIR addresses the project's potential growth-inducing impacts.
Finding for Potential Growth-Inducing impacts
The Seawater Desalination Project at Huntington Beach will not result in significant growth-
inducing impacts. Less than significant impact.
Facts in Support of Finding
As required under CEQA, Section 6.2 of the DREIR included a discussion of the ways in which
the Seawater Desalination Project at Huntington Beach could be growth-inducing. Under
CEQA, growth inducement is not considered necessarily detrimental, beneficial, or of little
significance to the environment. Typically, the growth-inducing potential of a project would be
considered significant if it fosters growth or a concentration of population in excess of what is
assumed in pertinent master plans, land use plans, or in projections made by regional planning
agencies such as the Southern California Association of Governments (SCAG). Significant
growth impacts could also occur if the project provides infrastructure or service capacity to
City of Huntington Beach August 22, 2005
Page 18 of 47
Seawater uesaiination vroject at runtington beacn FINUINiUJ Vt- t-AU I J
Recirculated EIR No.00-02
accommodate growth beyond the levels currently permitted by local or regional plans and
policies. It must first be noted that the project will sell water on a wholesale basis to water
agencies who in turn will sell the water to customers at retail prices. The project does not
propose to sell water at a retail level. On page 3-30, the DREIR explains how the water
produced by the proposed seawater desalination facility will be delivered into the regional
distribution system operated by the Metropolitan Water District of Southern California ("MWD").
The regional system operated by MWD serves Orange County and most of the South Coast
Hydrologic Region. It will be up to the Orange County water agencies served by that system to
determine how best to allocate the water produced by the project. The project may have the
potential to indirectly induce growth because additional or supplemental water supplies will be
made available to the County of Orange as a result of the project's implementation. However,
while the provision of additional/supplemental water realized by the desalination facility may be
characterized as reducing one of the barriers to growth, implementation of the project will not
necessarily induce growth because the new water supply made available by the project may be
required to simply replace anticipated reductions in available imported water supplies. Growth
in Orange County will occur with or without the Seawater Desalination Project at Huntington
Beach. Implementation of the project will provide greater flexibility for Orange County water
agencies to meet existing water supply needs during times of drought, but it is only one part of
the solution to meet existing and future water needs in Orange County. Other water supplies
such as imported water, groundwater replenishment, water reuse, and more aggressive forms
of conservation must also be considered as part of the solution because the project would only
result in the addition of less than eight percent (8%) of the existing supplies used in Orange
County. With a projected population growth of approximately two percent (2%) per year, the
project's water supply would soon fail to keep up with existing growth projections for Orange
County.
A Growth Assessment and General Plan Evaluation was completed and incorporated in the
FREIR as Appendix P and discussed in Section 6.2, Growth-Inducing Impacts of the Proposed
Action. The study looked at the projected number of dwelling units at build out in the County
based both on the Housing Elements of all the jurisdictions within the County and the Orange
County Projections adopted by the Orange County Council of Governments. The study also
identified 12 planned new residential development projects of 500 dwelling units or more in the
county which are required by law to identify and verify the water sources available to serve the
project. Seven of the projects have identified water sources independent of the desalination
project. The desalination project cannot be ruled out as a water source for one or more of the
five planned residential projects that have not yet identified water sources.
The FREIR notes that typically, the growth-inducing potential of a project would be considered
significant if it fosters growth or a concentration of population in excess of what is assumed in
pertinent general plans, or in projections made by regional planning agencies. Even if the
project were relied upon to serve a new development of 500 dwelling units or more, it would not
foster growth in excess of that already assumed and projected in pertinent planning documents.
The FREIR acknowledges that since no water supply agreements have been executed with
water agencies within Orange County, the precise locations/uses where the desalinated water
would be allocated are not known. Therefore, there is a potential for the project to induce
growth in unidentified areas. However, all proposed projects and water sources would be
subject to environmental analysis prior to approval. The FREIR concludes that in consideration
of population and housing projections within the County and the recognized need for seawater
desalination as a supply source within the water management and other related plans discussed
in the FREIR, any impacts in regards to growth inducement would be less than significant. The
project will not result in significant growth-inducing impacts.

conditions, project design features and incorporation of mitigation measures CON-37 through
CON-44, inclusive. Less than significant impact with mitigation.
Facts in Support of Finding
As explained in Section 5.9 of the DREIR, potential short-term construction related impacts in
regards to biological resources have been eliminated or substantially lessened to a level of less
than significant by standard conditions, appropriate project design features and through
incorporation of mitigation measures CON-36 through CON-43, inclusive. Impacts to biological
resources will be reduced by performing focused surveys to determine the potential for
endangered species and other sensitive species and coordinating with the USFWS to avoid
special status species or to develop mitigation if avoidance is not possible, by preparing and
implementing a Frac-Out Contingency Plan, and by performing a jurisdictional delineation and
obtaining and complying with the appropriate permits, if applicable.
Finding for Cultural Resources
The proposed Seawater Desalination Project at Huntington Beach may have adverse short-term
construction related impacts in regards to cultural resources. However, changes or alterations
have been required in, or incorporated into, the project that avoid or substantially lessen the
potential significant environmental effects identified in the DREIR, including standard conditions,
project design features and incorporation of mitigation measures CON-45 through CON-47.

J. IMPACTS RELATED TO OCEAN WATER QUALITY AND MARINE BIOLOGICAL
RESOURCES
Section 5.10 of the DREIR addresses the project's potential impacts related to ocean water
quality and marine biological resources which are addressed above, in Section 3.0-J of this
Statement of Facts and Findings.
K. IMPACTS RELATED TO PRODUCT WATER QUALITY
Section 5.11 of the DREIR addresses the project's potential impacts related to product water
quality. The DREIR addresses three topics, all of which are addressed in this Section:
• Product Water Quality
• Product Water Reliability
• Orange County Water Distribution System
Finding for Product Water Quality
The proposed desalination project product water quality may be impacted by several factors,
including ocean water quality fluctuations, red tide algal bloom events, HBGS non-routine
operations and RO membrane performance. However, changes or alterations have been
required in, or incorporated into, the project that avoid or substantially lessen the potential
significant environmental effects identified in the DREIR, including project design features and
incorporation of mitigation measures PW-1 through PW-3, inclusive. Less than significant
impact with mitigation.
Facts in Support of Finding
The product water of the proposed seawater desalination facility may be impacted by natural
changes in ocean water salinity, temperature, turbidity and pathogen concentration. Typically,
ocean water salinity and temperature changes are triggered by natural seasonal events. As
discussed in DREIR Section 5.10, OCEAN WATER QUALITY and the Watershed Sanitary
Survey (Appendix E of the DREIR), the intake ocean water turbidity and pathogen concentration
changes are mainly driven by rain events.
In order to maintain a consistent quality of desalinated product water, the applicant would be
required to obtain a drinking water permit from the California Department of Health Services
(DHS) that would address monitoring of source water quality and its effects on product water
quality. The applicant has been working with DHS for the last four years to obtain such a
City of Huntington Beach August 22, 2005
Page 31 of 47
Seawater uesalination Frolect at runtington beach 1-iNUINU5 Ur rHL r5
Recirculated EIR No.00-02
permit. On August 10, 2002, DHS issued a conceptual approval letter for the Seawater
Desalination Project at Huntington Beach.
The desalination facility intake water quality in terms of turbidity (which is a surrogate indicator
for potential elevated pathogen content) and salinity would be measured automatically and
monitored continuously at the desalination facility intake. Instrumentation for continuous
monitoring and recording of these parameters would be installed at the desalination facility
intake pump station. in event of excessive increase in intake seawater turbidity and/or salinity,
this instrumentation would trigger alarms that would notify desalination facility staff. If the intake
pathogen count reaches a preset maximum level, this instrumentation would automatically
trigger chlorination of the source water, thereby reducing the source water pathogens to
acceptable levels even before the water reaches the RO treatment facilities. In addition to the
automation provisions, turbidity and salinity would also be measured manually by the
desalination staff at least once a day and the intake seawater would be analyzed for pathogen
content at least once per week. In the event of elevated intake seawater turbidity, laboratory
pathogen content analysis would be performed more frequently.
In addition to the intake water quality monitoring instrumentation, the desalination facility
pretreatment filtration facilities would be equipped with filter effluent turbidimeters and particle
counters. This equipment would allow facility operators to continuously monitor pretreatment
filter performance and to trigger adjustments of desalination facility operations to accommodate
intake water quality changes.
Desalinated product water quality would also be monitored continuously for salinity and chlorine
residuals and would be tested frequently for pathogen content.
In summary, desalinated product water quality would be tested in accordance with the
requirements of the California Code of Regulations (Title 22) and the DHS. Product water
quality impacts due to ocean water quality fluctuations are not anticipated to occur upon
implementation of the design features described above.
The desalination facility would be designed to maintain high quality potable water (consistent
with regulatory standards) in the event of a red tide event. As explained in Section 5.11 of the
DREIR, it would have a number of provisions/barriers to protect against the passage of red tide-
related algal organic compounds through the treatment processes. These include a deep intake
configuration to minimize algae entrainment, the chlorination of intake seawater, an enhanced
coagulation of intake seawater, a microfiitration or dual media sand filtration algae barrier,
microfiltration or dual media sand filter covers, a cartridge filter algae barrier, the RO
membranes, a final disinfection, and an emergency facility shutdown procedure. Also, there are
no documented cases of red tide health or safety problems associated with the operation of RO
seawater desalination facilities worldwide which is indicative of the capability of these systems
to perform reliably and effectively under red tide conditions.
Unusual activities at the HBGS, such as seawater emergency intake pump shut downs and
failures, electricity equipment malfunctions, excessively high temperature of the cooling water,
etc., may impact product water quality and desalination facility performance.
The Seawater Desalination Project at Huntington Beach would have six different provisions
incorporating several protection/notification devices to account for non-routine operations at the
HBGS:
City of Huntington Beach August 22, 2005

Seawater Desalination Project at Huntington beach t-iNu1NU5 Ut- VAU 15
Recirculated EIR No.00-02
❖ Automatic control interlock between HBGS pumps and desalination facility intake
pumps: The shutdown controls of the desalination facility intake pumps would be
interlocked with the HBGS pumps, so when HBGS pump operation is discontinued to
prepare for heat treatment, non-routine or even routine pump shutdown, this would
automatically trigger an alarm at the desalination facility along with shutdown of the
desalination intake pumps. After this emergency shutdown, the intake pumps would
have to be started up manually, and the operations staff would be required to check the
reason of shutdown with the HBGS staff before restarting the treatment facility intake
pumps.
❖ Continuous Intake Pump Flow Measurement Devices: Seawater intake pumps would be
equipped with flow meters, which would record the pumped flow continuously. if the
intake flow is discontinued for any reason, including non-routine HBGS operations, this
would trigger automatic intake pump shutdown.
❖ Continuous Intake Water Temperature Measurement Devices: The desalination facility
intake pump station would be equipped with instrumentation for continuous
measurement of the intake temperature. Any fluctuations of the intake temperature
outside preset normal limits would trigger alarm and intake pump shutdown. This
monitoring equipment would provide additional protection against heat treatment or other
unusual intake water quality conditions.
❖ Continuous Intake Water Salinity/Conductivity Measurement Devices: The desalination
facility intake pump station would be equipped with instrumentation for continuous
measurement of the intake seawater salinity. Any fluctuations of the intake salinity
outside preset normal operational limits would trigger an alarm and initiate intake pump
shutdown. This monitoring equipment would provide additional protection against
discharge of unusual fresh water/surface water streams in the facility outfail.
Continuous Intake Water Oil Spill/Leak Detection Monitoring Devices: The desalination
facility intake pump station would be equipped with instrumentation for oil spill/leak
detection. Detection of oil in the intake water even in concentrations lower than 0.5 mg/L
would automatically trigger an alarm and initiate intake pump shutdown. This monitoring
equipment would provide additional protection against unusual intake water quality
conditions.
❖ Routine Communication with HBGS Staff: The desalination facility staff of each shift
would be required to contact HBGS personnel at least once per shift and enquire about
unusual planned or unplanned events at the HBGS. If non-routine operations are
planned at the HBGS, the desalination facility would be informed and would modify
desalination facility operations accordingly.
Implementation of the six provisions described above would minimize impacts in this regard to
less than significant levels.
As the RO membrane elements age, their rejection capabilities decrease. This may trigger a
change in product water quality from the Seawater Desalination Project at Huntington Beach.
The RO system membrane performance would continuously monitor feed seawater and
permeate conductivity and the differential pressure through the membranes. If permeate salinity
(i.e. total dissolved solids [TDS]) concentration exceeds the design level, membranes would be
cleaned to recover their original performance capabilities. In addition, an average of 10 to 15
City of Huntington Beach August 22, 2005
Page 33 of 47
Seawater uesallnation Project at tiuntington tseacn HNUINU6 Ut- t'AU 16
Recirculated EIR No. 00-02
percent of the membrane elements would be replaced every year, thereby maintaining the
product water quality at a steady level.
The Seawater Desalination Project at Huntington Beach would produce product water with
lower TDS levels than that currently delivered to Orange County water purveyors by MWD. The
TDS product water quality estimate of 350 mg/L is based on the use of high-rejection seawater
desalination membranes at the second year of desalination facility operations. Typically, during
the first two years of facility operations, the average product water quality TDS concentration
would be lower than 350 mg/L. After the second year of operations, a portion (typically 10 to 15
percent per year) of the desalination facility membrane elements would be replaced to maintain
the product water quality close to the target TDS concentration of 350 mg/L. Membrane
replacement is a standard approach commonly used in seawater desalination facilities to
maintain product water quality at a long-term steady target level. In addition, chloride and
sodium are estimated to average 180 mg/L and 120 mg/L, respectively.
These estimated water quality levels for TDS, chloride, and sodium are well below the newly
adopted narrative water quality objectives in the amended Basin Plan and when the desalinated
water is integrated into the water supply system it is unlikely that recycled water would exceed
the amended Basin Plan narrative water quality objectives.
The desalination facility would use industry standard eight-inch desalination membrane
elements, which are available from a number of specialized membrane manufacturers. The
membrane element manufacturers and their products pre-qualified for this project are:
- Hydranautics (SWC3 or better)
- Filmtec/Dow(SW30HR-380 or better)
- Koch/Fluid Systems (TFC2822SS or better)
- Toray (SU820L or better).
Key design membrane element parameters common for the products of these suppliers are:
- Membrane Type: Spiral-wound, thin film composite;
- Applied Flux: eight to 12 gpd/sf at recovery rate of 45 to 50 percent;
- Nominal Salt Rejection: 99.6 percent or higher;
- Applied Pressure: 800 to 1,100 pounds per square inch (psi);
- Maximum Pressure Drop per Element: 10 psi;
- Maximum Feed Water SDI (15 min): 5.0;
- Free Chlorine Resistance: less than 0.1 mg/L;
- Operating pH Range: two to 11; and
QA/QC Membrane Production and Testing Procedures.
The actual membrane element that would be used for the proposed desalination facility would
be selected during the detailed engineering design phase of this project. The product water
projections are performed for two conditions: new membranes at facility start up and
membranes at the second year of facility operations. All projections are completed for low flow
scenario conditions in terms of intake water salinity and temperature and membrane
performance characteristics.
At the beginning of the desalination facility operation the TDS concentration of the RO system
permeate is projected to be between 226 and 308 mg/L, and at the end of the second year of
desalination facility operations is projected to be between 257 and 349 mg/L (based on
projections of product water quality and membrane performance in accordance with modeling
City of Huntington Beach August 22,2005
Page 34 of 47

Recirculated EIR No.00-02
specifications provided by two of the four membrane suppliers, Toray and Hydranautics). As
previously indicated, the permeate water quality would be maintained at a second-year
operations level over the entire 30-year period of facility operations by replacement of a portion
of the membrane elements every year. It should be noted that the projections above are for the
water quality of the RO system permeate as it exits the desalination system. Prior to
distribution, the desalination facility permeate would be conditioned by lime and carbon dioxide
for stabilization and corrosion control, and with chlorine for final disinfection. The addition of
these conditioning chemicals would increase the final product water TDS concentration by 30 to
50 mg/L. Therefore, at facility start-up the TDS of the product water delivered to the distribution
system is expected to be in a range of 260 to 340 mg/L, while for the entire 30-year period of
facility operations the TDS concentration would be in a range of 300 to 400 mg/L and would
average 350 mg/L.
The projections presented above are developed using conservative assumptions for the type
and performance of the membrane elements, intake water salinity and temperature. The
applicant's previous pilot testing experience in Tampa and Carlsbad and the actual performance
of the same Toray membranes in Trinidad indicate that the membrane manufacturer projections
carry a safety factor of 10 to 15 percent and the actual product water quality is always better
than that projected by the software.
Advances in membrane technology over the next 30 years are expected to yield membrane
elements capable of producing water of TDS concentration below 300 mg/L for most of the
useful life of the desalination facility. Therefore, the projected product water TDS concentration
of 350 mg/L is a reliable and conservative estimate of the potable water quality that would be
delivered to the distribution system by the Seawater Desalination Project at Huntington Beach.
As described in Section 3.0, PROJECT DESCRIPTION, the facility would be capable of meeting
all drinking water standards through multiple treatment processes, which include: pretreatment
filters; cartridge filters; reverse osmosis membranes; and product water conditioning and
disinfection facilities. A comparison between the product water quality of the Seawater
Desalination Project at Huntington Beach and the DHS primary and secondary water quality
standards is presented in DREIR Table 5.11-3, PRODUCT WATER QUALITY COMPARISON.
Review of this table indicates that the desalination facility product water quality meets all current
DHS water quality MCL standards. The project would also be consistent with all requirements
of the SARWQCB Basin Plan. Thus, impacts in this regard would not be significant.
In addition to the Safe Drinking Water Act, which sets the primary and secondary MCLs for
water quality constituents, the California DHS has established health-based advisory levels,
known as "action levels", for specific chemicals which may be found in drinking water. As
explained in Section 5.11 of the DREIR, boron is the only compound that is detectable in the
product drinking water from the seawater desalination facility. After the reverse osmosis
treatment process the desaited water boron level is approximately 0.6-0.8 mg/l, which is below
the DHS action level. Impacts to the product water quality are less than significant.
Finding for Product Water Reliability
The proposed desalination project product water reliability may be impacted by earthquakes or
other unscheduled outages. However, changes or alterations have been required in, or
incorporated into, the project that avoid or substantially lessen the potential significant
environmental effects identified in the DREIR, including project design features and
incorporation of mitigation measure PW-4. Less than significant impact with mitigation.

Recirculated EIR No.00-02
Facts in Support of Finding
The desalination facility operations would be fully automated and key systems would be
provided with redundant equipment and controls per the requirements of Title 22 of the
California Code of Regulations. In the event of an underground booster pump station power
outage, the booster pump station would be equipped with on-site power generators that would
allow their operation to continue even if the main source of power supply has been interrupted.
The desalination facility would be provided with two independent sources of power supply,
which includes an electrical power grid and/or the HBGS auxiliary reserve bank to assure
uninterrupted operations during emergencies. The desalination facility would be manned 24
hours per day, 365 days per year by skilled and certified operators, which would coordinate
facility and pump station operations with that of all other water purveyors delivering water to or
operating the water distribution system facilities.
As a part of desalination and pumping station operations, the operations staff would develop an
earthquake mitigation and preparedness plan, which would be coordinated with the City of
Huntington Beach. This plan would define coordination measures to assure continuous facility
operations and water delivery under earthquake emergency conditions.
The desalination facility would be designed with one standby reverse osmosis train to provide
additional reliability of water production and supply. Typically, desalination facilities, including
the existing desalination facilities in California, are designed to operate with all available reverse
osmosis trains in operation at all times. During the times of potential outages caused by
scheduled or unscheduled maintenance or emergency events, such as an earthquake, these
facilities operate at reduced capacity or are down for a certain period of time. The proposed
desalination facility would be designed to produce 50 mgd of product water with 12 RO trains,
and would be constructed with an additional 13th RO standby train, which can produce up to 4.2
mgd of water at any time. This additional train would provide increased reliability and
redundancy that exceeds current reliability standards and common practices for desalination
facility design. The proposed desalination facility would be the first facility in California with such
additional production standby capacity and reliability provisions.
The issues of reliability of the supply and emergency service provisions would be dictated by the
terms of the institutional agreements negotiated with the regional water purveyors (including
MWDOC and Metropolitan Water District) and by the terms of the water supply agreements
negotiated with potential customers that would purchase the product water produced at the
desalination facility. Thus, impacts are anticipated to be less than significant in this regard with
mitigation.
Finding for Orange County Water Distribution System
The introduction of the proposed desalination project product water into the existing Orange
County distribution system may result in impacts in regards to blended water quality, corrosivity,
chlorine residual, disinfection byproduct concentration, taste and odor or hydraulics. However,
changes or alterations have been required in, or incorporated into, the project that avoid or
substantially lessen the potential significant environmental effects identified in the DREIR,
including project design features and incorporation of mitigation measures PW-5 through PW-9,
inclusive. Less than significant impact with mitigation.

Facts in Support of Finding
As explained in Section 5.11 of the DREIR, blending could have water quality improvement
benefits, especially if the receiving agencies are predominantly using imported water, which has
higher levels of TDS, sulfate, hardness and disinfection byproducts than desalinated water. The
desalination facility would produce drinking water of very high and consistent quality, which
meets or exceeds all applicable regulatory requirements established by the EPA and the DHS.
The desalinated water would be produced applying state-of--the-art seawater RO membranes
which are capable of removing practically all contaminants in the source water: turbidity; taste,
odor, color, bacteria, viruses, salts, proteins, asbestos, organics, etc. Currently, EPA
recognizes RO membrane treatment as a best available technology for water treatment and for
meeting future water quality regulations. The desalinated water would have approximately 100
mg/L lower salinity (i.e. TDS) than the existing drinking water. The lower drinking water salinity
would result in better taste and lower overall water distribution system corrosivity. The
desalinated seawater would be softer than the existing water sources. Softer water has a
number of benefits such as: better taste; formation of less calcium deposits on household
appliances and cutlery; and lower detergent use. The desalinated water would have order-of-
magnitude lower disinfection byproducts, such as total trihalomethanes and halocetic acids, or
TTHM and HAA, respectively) concentrations than the existing drinking water (refer to the
DREIR Appendix N, DISINFECTION BYPRODUCT FORMATION STUDY). Disinfection
byproducts are well known carcinogens and their reduction in the drinking water as a result of
the blending of the desalinated water with other water sources would be an added benefit. The
blending of desalinated product water with existing distribution systems has less than significant
impacts.
As stated above, the proposed project would include several features to accommodate changes
in ocean water quality and red tide algal bloom events. In addition, in regards to corrosivity,
blending the desalinated product water with existing water from other sources may change the
water quality of the blend in terms of its corrosion effect on the existing water distribution
system. When evaluating potential short-term and long-term impacts of blending treated waters
from different sources, one of the most important considerations is the potential for corrosion of
pipes and residential fixtures. Excessive corrosion over time might lead to colored water in
homes, stained fixtures, pipe failures, and non-compliance with the Lead and Copper Rule. In
1992, the EPA promulgated the Lead and Copper Rule to protect drinking water consumers
from excessively high concentrations of lead and copper in the drinking water caused by
corrosion of household and public building plumbing systems. The rule sets limits for lead and
copper in samples collected from faucets with risk for elevated lead and copper concentrations.
The limits for lead and copper are 15 µg/L (micrograms per liter), and 1.3 mg/L, respectively.
Similar to all other potable water sources in the distribution system, product water from the
Seawater Desalination Project at Huntington Beach would be chemically conditioned at the
treatment facility prior to delivery to the distribution system to mitigate its corrosivity. Lime, in
combination with carbon dioxide, would be added for post-treatment stabilization of the RO
water as a source for pH and alkalinity adjustment and hardness addition. A corrosion control
study describing in detail the type and amount of corrosion control chemicals planned to be
used for this project are presented in Appendix O of the DREIR, DISTRIBUTION SYSTEM
CORROSION CONTROL STUDY
The product water from the seawater desalination facility would be suitable for delivery through
the existing water distribution system and would be comparable and compatible to the other
water sources currently delivering water to the same system. Prior to delivery to the water
distribution system the desalinated water would be conditioned using lime and carbon dioxide to
City of Huntington Beach August 22, 2005

achieve the following corrosion control driven water quality parameters, which are known to be
consistent with water currently distributed throughout Orange County:
• pHof8to 8.5,
• Langelier Saturation Index(LSI) of 0.0 to 0.5, and
• Alkalinity of 40 mg/L or higher.
These water goals are established based on current practices of the MIND, MINDOC, and most
water agencies and municipalities in Orange County. The water goals are rooted in the Safe
Drinking Water Act's water quality standards.
These water quality goals would be achieved by the addition of the following chemicals:
• Lime at dosage of 25 to 50 mg/L (average of 30 mg/L)
• Carbon dioxide at dosage of zero to 30 mg/L (average of six mg/L)
Adopting this proven corrosion control strategy would result in a non-corrosive product that can
be seamlessly integrated into the system.
In addition, a corrosion monitoring system would be installed in the proposed transmission
pipeline at points of interconnection with the existing water distribution system to ensure that the
proposed corrosion control measures are effective and adequate. As such, impacts in regards
to corrosion are not anticipated to be significant upon implementation of the design features
described above.
The desalinated product water would be disinfected prior to delivery to the distribution system.
Chlorine, in the form of sodium hypochlorite, would be added as a disinfectant to meet DHS
water quality standards for potable water disinfection. The desalted water would meet current
imported water disinfection methods so as to not change any disinfection protocol currently
being used by water agencies.
As explained in Section 5.11 of the DREIR, the desalinated water would be chloraminated by
sequential application of sodium hypochlonte and ammonia to achieve a chloramine residual
concentration at the point of delivery to the distribution system is in a range of two to 2.5 mg/L.
A detailed description of the proposed chloramination process is provided in Appendix N of the
DREIR, DISINFECTION BYPRODUCT FORMATION STUDY. This study confirms that after
blending of the chloraminated product water from the desalination facility with disinfected
product water from other sources, the chloramine residual of the blend meets the target level in
the distribution system of two to 2.5 mg/L. As such, impacts in this regard are not anticipated to
be significant.
As explained in Section 5.11 of the DREIR, blending desalinated water with existing sources of
supply would result in a product that is comparable to existing supplies and meets all
disinfection byproduct limits. Desalinated seawater contains lower levels of organics than
existing Orange County sources. Therefore, blending of desalinated water with other source
waters in the distribution system would have a beneficial effect, and would lower the overall
disinfection byproduct concentration of the blend. The results of Appendix N in the DREIR,
DISINFECTION BYPRODUCT FORMATION STUDY confirm the beneficial effect of the
desalinated water on the blended water quality in terms of disinfection byproducts. As such,
impacts in this regard are not anticipated to be significant.

In regards to hydraulics and/or pressure surges, implementation of the proposed project may
have hydraulic impacts on the regional water distribution system. A total of three pump stations
would be necessary for operation of the project: 1) a product water pump station at the
desalination facility site; 2) the OC-44 underground booster pump station in unincorporated
Orange County; and 3) the Coastal Junction underground booster pump station in Irvine.
Project implementation could potentially alter the flow rate and pressure of multiple transmission
lines serving the vicinity. Based on hydraulic modeling performed for the proposed project, the
following water transmission mains in the project vicinity are not anticipated to be impacted by
the proposed project (it is assumed that all facilities discussed below have design features to
prevent hydraulic surges):
East Orange County Feeder#2
❖ Irvine Cross Feeder
❖ Coast Supply Line
❖ Aufdenkamp Transmission Main
❖ Tri-Cities Transmission Main
❖ Newport Beach Wells Supply Line
However, the hydraulic characteristics of the OC-44 pipeline may be affected in one of two
ways, depending on whether the pipeline segment in question is east or west of the proposed
OC-44 connection point: 1) west of the proposed OC-44 connection point, the flow rate and flow
direction would remain unchanged, while a change in water pressure would be negligible (a
change of less than five psi); and 2) east of the proposed connection point, the direction of flow
would be reversed, the flow rate would increase, and water pressure would decrease. It is
anticipated that maximum flow velocity through this portion of the pipeline would be 7.5 fps. All
flow rate, pressure, and velocity changes, which may occur in the existing pipelines, are within
pipeline design specifications.
In addition, the hydraulic characteristics of the East Orange County Feeder No. 2 (EOCF #2)
may be affected in one of two ways, depending on whether the pipeline segment in question is
north or south of the Coastal Junction (the point at which the Tri-Cities and Aufdenkamp
Transmission Mains connect to the EOCF #2): 1) north (upstream) of the Coastal Junction, the
flow rate within EOCF #2 would decrease (this decrease may allow water pressure to rise, but
the resulting change in water pressure would be well within allowable design pressure for the
existing pipeline); and 2) south (downstream) of the Coastal Junction, the direction of flow would
be reversed, the water pressure would rise, and the flow rate would increase to a maximum
velocity of 3.6 fps. Based on the hydrodynamic model, the pressure class of the existing
pipeline is of sufficient strength to accommodate changes incurred by the proposed project.
Thus, impacts in this regard would not be significant.
Appendix D of the DREIR, PRESSURE SURGE ANALYSIS, provides a discussion of potential
impacts of the three pump stations associated with the project. The report includes the effect of
pressure surges on:
❖ The proposed desalinated water 42-to 48-inch pipeline (between the desalination facility
and the OC-44 transmission main)
❖ East Orange County Feeder#2
•:- Irvine Cross Feeder
❖ Coast Supply Line
❖ Aufdenkamp Transmission Main
❖ Tri-Cities Transmission Main

Analysis concludes that in the event of a loss of power to the booster pump stations, a low-
pressure wave is predicted to propogate out from the discharge site of each booster pump
station and into the associated pipelines. As the water travels toward its applicable destination
(reservoirs, demand locations, and booster pump stations), the low-pressure waves cause the
pipeline pressure to fall. Simultaneously, a pressure upsurge wave is predicted to propagate
out from the suction side of the OC-44 and Coastal Junction pump stations.
Following the loss of power to the pump station located at the desalination site, a vapor
condition is created in the desalinated water conveyance pipeline. When the product water
conveyance pipeline is re-pressurized by a reflected waterhammer wave, any vapor cavities that
are formed would collapse, and may create extremely high local pressure spikes that may
damage the pipeline, resulting in premature corrosion and the development of leaks. When
subjected to negative pressure, a leak could become a source of pathogen intrusion. If the
piping does not have sufficient strength to withstand a full vacuum, the pipeline could collapse
under such low pressures.
To eliminate large negative pressures and the possibility of vapor cavity formation in the delivery
pipeline system above, surge protection measures for proposed project facilities are
recommended as follows:
❖ Incorporation of pressurized surge tanks at booster pump station locations; and
❖ Vacuum relief and air release valve improvements.
Hydraulic modifications recommended for the existing water distribution system include the
following:
❖ Hydraulically operated isolation valves;
❖ Elimination of existing valves; and
❖ Pressure control valve improvements.
Additional modeling would be performed during the design phase of the project to confirm that
the proposed project would not have significant impacts on regional water transmission facilities.
5.0 ENVIRONMENTAL EFFECTS WHICH WOULD REMAIN
SIGNIFICANT AND UNAVOIDABLE AFTER MITIGATION
IMPACTS RELATED TO CONSTRUCTION —AIR QUALITY
Section 5.9 of the DREIR addresses the project's potential short-term construction related
impacts. The DREIR addresses nine topics, one of which (air quality) is addressed in this
Section. The remaining topics are addressed in Section 4.0-1 of this Statement of Facts and
Findings.
Finding for Short-Term Air Quality
The proposed Seawater Desalination Project at Huntington Beach may have adverse short-term
construction related impacts in regards to air quality. Changes or alterations have been
required in, or incorporated into, the project that avoid or substantially lessen the potential
significant environmental effects identified in the DREIR, including standard conditions, project
design features and incorporation of mitigation measures CON-9 and CON-10. In addition, the
South Coast Air Quality Management District and California Air Resources Board have
jurisdiction over stationary and mobile emission sources, respectively. Even after incorporation

of mitigation measures CON-9 and CON-10, the Project will result in an unavoidable significant
impact in regards to short-term construction related reactive organic gases (ROG), nitrogen
oxides (NO,), and carbon monoxide (CO). Specific economic, legal, social, technological, or
other considerations, including considerations for the provision of employment opportunities for
highly trained workers, make infeasible additional mitigation measures or alternatives identified
in the DREIR, The City of Huntington Beach is adopting the Statement of Overriding
Considerations set forth in Section 7.0 of this Statement of Findings and Facts to address this
impact of the Project.
Facts in Support of Finding
Construction related air quality impacts will be mitigated through preparation of a dust control
plan and adherence to City standards and South Coast Air Quality Management District Rules
402 and 403. As detailed within Section 5.9 of the DREIR, and despite the implementation of
standard conditions, project design features and mitigation measures CON-9 and CON-10,
significant and unavoidable short-term air quality impacts remain. The proposed project is
anticipated to exceed South Coast Air Quality Management District (SCAQMD) thresholds in
regards to short-term air emissions (remediation, demolition, construction). Mitigation measures
will be implemented, but these measures are unable to reduce ROG, NOX, and CO emissions to
.a less than significant level according to SCAQMD thresholds. Thus, air quality impacts in this
regard are considered an unavoidable significant impact of the Seawater Desalination Project at
Huntington Beach. This impact is overridden by the project benefits as set forth in the
Statement of Overriding Considerations (Section 7.0 of this Statement of Facts and Findings).
There are no feasible alternatives that could avoid this significant impact. Moreover, the South
Coast Air Quality Management District and California Air Resources Board have jurisdiction
over stationary and mobile emission sources, respectively.
6.0 FINDINGS REGARDING PROJECT ALTERNATIVES
Pursuant to Public Resources Code Section 21002 and the CEQA Guidelines Section 15126.6,
an EIR must assess a reasonable range of alternatives to the project action or location.
(a) Section 15126.6 places emphasis on focusing the discussion on alternatives
which provide opportunities for eliminating any significant adverse environmental
impacts, or reducing them to a level of insignificance, even if these alternative
would impede to some degree the attainment of the project objectives, or would
be more costly. In this regard, the EIR must identify an environmentally superior
alternative among the other alternatives.
(b) As with cumulative impacts, the discussion of alternatives is governed by the
"rule of reason".
(c) The EIR need not consider an alternative whose effect cannot be reasonably
ascertained, or does not contribute to an informed decision-making and public
participation process.
The range of alternatives is defined by those alternatives, which could feasibly attain the
objectives of the project. Accordingly, Section 6.0 of the DREIR analyzes various alternatives to
the proposed project in evaluating the opportunity for avoiding or substantially lessening
environmental impacts. Section 6.0 of the DREIR provides descriptions and analysis of each
alternative in adequate detail to allow the decision-maker(s) to evaluate the proposed project in
comparison to identified alternatives.

Recirculated EIR No.00-02
As directed in CEQA Guidelines section 15126.6(c), an EIR shall include alternatives to the
project that could feasibly accomplish most of the basic objectives of the project. A specific
objective of the project was to provide a reliable local source of drinking water. While water
conservation efforts have resulted in successfully stretching the existing water supply, and more
gains from conservation are projected for the future, conservation in and of itself is not a "source
of drinking water." It must also be emphasized that although an objective of the project is to
provide a reliable local source of drinking water, most of the project objectives emphasize
development of a drinking water source that is "independent of," "decreases pressures on" and
"minimizes demands on" existing drinking water supplies (i.e., imported water supplies and local
groundwater supplies). (See the list of project objectives on page 6-1 of the DREIR.)
Desalinated seawater is unique because it does not fall into the categories of either "imported
water" or"local groundwater." In contrast, water reuse projects are dependent on existing water
supplies because, by their very nature, they "recycle" existing imported or local groundwater
supplies. In addition, water reuse projects do not produce direct use potable/drinking water.
DHS will not allow recycled water to be used as a direct use potable water source. Because
there are no feasible alternative water sources to evaluate that meet the objectives of the
project, an alternative water source"alternative" was not included in the DREIR.
As directed in CEQA Guidelines section 15126.6(c), an EIR shall include alternatives to the
project that could avoid or substantially lessen one or more of the significant effects. The
DREIR notes (at page 6-1) that with the exception of short-term air quality emissions associated
with construction activities, "all potentially significant impacts" (which includes potential impacts
to marine organisms and water quality) can be "mitigated to less than significant levels."
Therefore, it is not anticipated that increased conservation efforts or any alternative water
source (assuming there is one) will avoid or substantially lessen significant impacts when
compared to the project.
Section 6.0 of the DREIR evaluates five ternatives, including a "No Project/No Development'
alternative, "Alternative Site" alternative, "Alternative Ownership and Operation" alternative,
"Alternative Project Design" alternative, and "Reduced Facility Size" alternative.
The "No Proiect/No Development' alternative conflicts with the primary purpose of the proposed
project, and is not being considered by the City for the following reasons:
The "No Project/No Development" alternative would:
• not meet basic project objectives;
• not remediate petroleum hydrocarbon contamination known to exist on-site;
• not minimize demand on existing imported water system;
• not create ecosystem and biologic resource benefits due to decreased pressures on existing
water resources;
• leave the existing degraded, abandoned fuel oil storage tanks in place; and
• not preclude site development of a similar or worse nature.

The "Alternative Site" alternative would potentially result in impacts greater than or equal to
those of the proposed project situated in Huntington Beach (depending on site-specific
conditions). This alternative would implement the project on either a site adjacent to the
proposed subject site (identified in the Initial Study/NOP for this project) or within the City of San
Clemente, City of Dana Point, or in San Onofre. This alternative is not being considered by the
City for the following reasons:
The"Alternative Site" alternative would:
• not substantially reduce identified impacts associated with the proposed project;
• not avoid the unavoidable significant impact for short-term air quality;
• result in potentially greater impacts for those alternative sites requiring a new
ocean intake/outfall;
• may result in significant aesthetic and/or marine biological impacts; and
• would have greater impacts due to sensitive surrounding areas.
The "Alternative Ownership" Alternative would not change any of the design or operational
features of the project. Rather, this alternative consists of the exact same project owned and
operated by a public entity. The project proponent, a private entity, has already obtained lease
rights to the site through negotiations with the current land owner(AES Huntington Beach, LLC).
For this alternative to be feasible, a public entity would first need to negotiate with the applicant
or otherwise obtain lease rights to the site. Assuming that lease rights of the site were acquired
by a public entity, this alternative would result in the same environmental impacts as the
proposed project (under private ownership). Consequently, the "Alternative Ownership"
alternative and the project as proposed would result in the same potential impacts on the
environment.
The "Alternative Project Design" alternative would incorporate a different method of desalination
(such as multi-effect distillation, or MED) or an alternative seawater intake collection system
(such as vertical wells, Ranney wells, infiltration galleries, and seabed infiltration systems). The
MED alternative is infeasible due to the extreme height required for operation of the vertical
tubes (300 feet) and the dependency on an electrical power plant for generation of steam.
Alternative intake methods are infeasible primarily due to the number of vertical/Ranney wells

Recirculated E1R No.00-02
necessary for a 50 mgd project (at least 24 individual wells), and the area of disruption
necessary for an infiltration gallery or seabed infiltration system.
An alternative discharge location (the Orange County Sanitation District [OCSD] outfall) was
also analyzed as an alternative. This alternative is also rejected, since OCSD has indicated that
they do not have the capacity to accommodate the waste stream from the proposed
desalination project.
The "Alternative Project Design" alternative would:
• Not substantially reduce impacts in comparison to the proposed project; and
• Be either technically or financially infeasible to implement.
The "Reduced Facility Size" Alternative would reduce the output of project water to
approximately 25 mgd. The design and operation of the proposed desalination facility would
generally remain the same. However, this alternative would reduce the size of the facility, the
amount of seawater required to produce water, and the amount of concentrated seawater
discharged back into the HBGS outfall.
The 25 mgd alternative would not significantly reduce potential environmental impacts when
compared to the proposed project. In addition, this alternative would result in a substantial
decrease in the amount of desalinated water that could be produced, and thus a substantial
increase in the cost of the desalinated water. While the Reduced Facility Size alternative may
result in slightly reduced impacts in comparison to the proposed project, the 25 mgd alternative
would result in providing water at a cost that would not be acceptable to Orange County water
purveyors, and would not produce a sufficient amount of desalinated water to meet projected
future demand. Implementation of the 25 mgd alternative would not avoid the project's
identified unavoidable construction related air quality impact, and would reduce the water quality
benefits of the project as proposed. As such, this alternative is not presently under
consideration.
The"Reduced Facility Size" alternative would:
• Not provide a sufficient amount of water that would meet the projected future
water needs; and
• Reduce overall water supply reliability that is sustainable and independent of
climatic conditions.
7.0 STATEMENT OF OVERRIDING CONSIDERATIONS
Pursuant to Section 15093 of the CEQA Guidelines, decision-makers are required to balance
the benefits of a project against its unavoidable environmental risks in determining whether to
approve a project. In the event the benefits of a project outweigh the unavoidable adverse
effects, the adverse environmental effects may be considered "acceptable. The CEQA
Guidelines require that, when a public agency allows for the occurrence of significant effects
which are identified within the Final REIR but are not at least substantially mitigated, the agency
shall seek in writing the specific reasons the action was supported. Any statement of overriding
considerations should be included in the record of project approval and should be mentioned in
the Notice of Determination.
To the extent the significant effects of a project are not avoided or substantially lessened to a
level of insignificance, the City of Huntington Beach, having reviewed and considered the
information contained within the Final Recirculated Environmental Impact Report for the project,
City of Huntington Beach August 22, 2005
Page 44 of 47

Recirculated EIR No. 00-02
and having reviewed and considered the information contained within the public record, and
having balanced the benefits of the project against the unavoidable effects which remain, finds
that such unmitigated effects to be acceptable in consideration of the following overriding
considerations discussion.
The City finds that all feasible mitigation measures have been imposed to lessen project
impacts to a less than significant level where feasible, and furthermore, that alternatives to the
project are either infeasible because they have greater environmental impacts, do not provide
the benefits of the project, do not eliminate the project's unavoidable significant air quality
impact, or are otherwise socially or economically infeasible.
The environmental analysis undertaken for the Seawater Desalination Project at Huntington
Beach indicates that, while mitigation measures would be effective in reducing the level of
certain short-term air quality impacts, the project may still result in significant adverse impacts in
regards to short-term air quality. It should be noted that the project's unavoidable adverse
impacts would occur under current General Plan designations.
The City of Huntington Beach, as lead agency and decision-maker for the project, has reviewed
and considered the information contained in the Final REIR prepared for the Seawater
Desalination Project at Huntington Beach and the public record. The City finds that the benefits
of the Project include the following:
❖ The Seawater Desalination Project at Huntington Beach will provide a reliable
source of potable water to Orange County that is sustainable independent of
climatic conditions and the availability of imported water supplies and local
groundwater supplies. The Project offers Orange County's water agencies up to
50 million gallons per day (MGD) or 56,000 acre-feet of water per year to include
in their portfolio of available water resources. Water conservation efforts have
resulted in successfully stretching the developed water supply, and more gains
from conservation are projected for the future. Still, the California Department of
Water Resources predicts that the South Coast Region (and the entire State) will
face significant water shortages by the year 2020. While the amount of water
produced by the Project is only a small percentage of the current 650 MGD
(710,000 acre-feet per year) Orange County water demand, it is an important
drought-proof, renewable supply that will enhance the overall portfolio of water
resources available to Orange County water agencies.
❖ The Seawater Desalination Project at Huntington Beach will provide product
water that meets the requirements of the Safe Drinking Water Act (SDWA) and
the California Department of Health Services (DHS).
The Seawater Desalination Project at Huntington Beach will reduce the salt
imbalance of current imported water supplies by providing a potable water source
with lower salt loads for blending with existing supplies.
❖ The Seawater Desalination Project at Huntington Beach will remediate the
subject site of on-site contaminants resulting from approximately 35 years of use
as a fuel oil storage facility thereby protecting the health and safety of those in
the surrounding community.
❖ The Seawater Desalination Project at Huntington Beach will create ecosystem
and biological resources benefits that may accrue due to decreased pressures
on existing water sources. The Orange County Water District (OCWD) has
identified that Santa Ana River Groundwater Basin has been overdrafted by more

than 400,000 acre feet due to drought conditions of the last three years. The
Project could offset withdrawals from the groundwater basin during dry years,
allowing the Groundwater Basin to recharge. The Project could also offset
demands on imported supplies transported from the Colorado River and/or
Northern California, allowing more water to remain available for use in
environmentally sensitive areas in those locations.
❖ The Seawater Desalination Project at Huntington Beach will minimize demands
on the existing imported water system. Southern California could not exist
without its extensive imported water supply system. The Metropolitan Water
District of Southern California ("MWD"), together with many local water agencies,
operates numerous water facilities to transport, store and recycle water supplies
to meet the needs of Orange County and the surrounding Southern California
region. Given the announced cutbacks of water supply from the Colorado River
and the continuing environmental water demands on the State Water Project in
Northern California, the water produced by the Seawater Desalination Project at
Huntington Beach could be dedicated by Orange County water agencies to
simply replacing existing water supplies for current Orange County residents and
future generations.
V. The Seawater Desalination Project at Huntington Beach will provide a continuous
monitoring and protection of the Pacific Ocean water in the vicinity of the HBGS
intake pipeline located offshore from Huntington Beach.
❖ The Seawater Desalination Project at Huntington Beach will serve high quality
desalinated water through portions of the City distribution system and provide a
drought proofing of 33% of the City's imported water supply.
❖ The Seawater Desalination Project at Huntington Beach will provide a local
emergency water supply.
❖ The Seawater Desalination Project at Huntington Beach will improve the
aesthetics of the area through the demolition of three unused 40-foot high fuel
storage tanks and replacing them with lower profile, modern, and more attractive
structures.
❖ The Seawater Desalination Project at Huntington Beach will install perimeter
improvements including a 10 foot (Edison) to 20 foot (Newland) landscape
planter and an eight foot high wall along the project's street frontage for an
overall cohesive appearance with the HBGS facility along Newland Street.
❖ The Seawater Desalination Project at Huntington Beach will improve the
circulation in the area through the dedication and improvement of additional right-
of-way along Edison Avenue.
❖ The Seawater Desalination Project at Huntington Beach will provide a new
source of long term annual property tax revenue for the city, especially the
redevelopment zone located in the South East area of the City.
❖ The Seawater Desalination Project at Huntington Beach will provide a new
source of long term annual revenue for the city from Franchise Agreement.

❖ The Seawater Desalination Project at Huntington Beach will provide higher water
pressure in a portion of City's distribution system, thereby allowing the city to
realized a cost savings.
❖ The Seawater Desalination Project at Huntington Beach will provide these
benefits at no cost to the tax payers.
Based on this Statement of Facts and Findings and on all of the evidence presented, the City of
Huntington Beach finds that the benefits of the Seawater Desalination Project at Huntington
Beach (as described above) outweigh the adverse short-term air quality impacts associated with
the construction of Project (as described in Section 5.0 of this Statement of Facts and Findings).

MITIGATION MONITORING AND
REPORTING CHECKLIST
MITIGATION MONITORING PROGRAM
The California Environmental Quality Act (CEQA) requires that when a public agency completes
an environmental document, which includes measures to mitigate or avoid significant
environmental effects, the public agency must adopt a reporting or monitoring program. This
requirement ensures that environmental impacts found to be significant will be mitigated. The
reporting or monitoring program must be designed to ensure compliance during project
implementation (Public Resources Code Section 21081.6).
in compliance with Public Resources Code Section 21081.6, the attached MITIGATION
MONITORING AND REPORTING CHECKLIST has been prepared for Seawater Desalination
Project at Huntington Beach. This Mitigation Monitoring and Reporting Checklist is intended to
provide verification that all applicable Conditions of Approval relative to significant environmental
impacts are monitored and reported. Monitoring will include 1) verification that each mitigation
measure has been implemented; 2) recordation of the actions taken to implement each
mitigation; and 3) retention of records in the Seawater Desalination Project at Huntington Beach
file.
This Mitigation Monitoring Program delineates responsibilities for monitoring the project, but also
9 g 9 p g p J
allows the City of Huntington Beach flexibility and discretion in determining how best to monitor
implementation. Monitoring procedures will vary according to the type of mitigation measure.
Adequate monitoring consists of demonstrating that monitoring procedures took place and that
mitigation measures were implemented.
Reporting consists of establishing a record that a mitigation measure is being implemented, and
generally involves the following steps:
• The City of Huntington Beach distributes reporting forms to the appropriate entities
for verification of compliance.
• Departments/agencies with reporting responsibilities will, review the EIR, which
provides general background information on the reasons for including specified
mitigation measures.
• Problems or exceptions to compliance will be addressed to City of Huntington
Beach as appropriate.
• Periodic meetings may be held during project implementation to report on
compliance of mitigation measures.
• Responsible parties provide the City of Huntington Beach with verification that
monitoring has been conducted and ensure, as applicable, that mitigation
measures have been implemented. Monitoring compliance may be documented
City of Huntington Beach August 22, 2005

through existing review and approval programs such as field inspection reports
and plan review.
• The City of Huntington Beach or Applicant prepares a reporting form periodically
during the construction phase and an annual report summarizing all project
mitigation monitoring efforts.
• Appropriate mitigation measures will be included in construction documents and/or
conditions of permits/approvals.
Minor changes to the Mitigation Monitoring Program, if required, would be made in accordance
with CEQA and would be permitted after further review and approval by the City of Huntington
Beach. Such changes could include reassignment of monitoring and reporting responsibilities,
program redesign to make any appropriate improvements, and/or modification, substitution or
deletion of mitigation measures subject to conditions described in CEQA Guidelines Section
15162. No change will be permitted unless the Mitigation Monitoring and Reporting Program
continues to satisfy the requirements of Public Resources Code Section 21081.6.
