....
WHEREAS, the Final Program EIR on the Master Plan has been certified
in compliance with CEQA and the State CEQA Guidelines; and,
WHEREAS, the Master Plan identified the three separate and distinct
alternatives (the "scenarios") for the level of prescribed treatment of
wastewater; and,
WHEREAS the Final Program EIR has identified one or more significant
environmental effects resulting from implementation of actions, activities or
specific projects set forth in said Master Plan.
NOW, THEREFORE, the Boards of Directors of County Sanitation Districts
Nos. 1, 2, 3, 5, 6, 7, 11, 13 and 14 of Orange County, California,
DO HEREBY RESOLVE, DETERMINE AND ORDER:
I. FINDINGS
Section 1: That the Master Plan and the Final Program EIR have fully and
adequately addressed all three alternatives for the prescribed level of
treatment of was.tewater, and that the Boards have determined· that the treatment
alternative described as Scenario No. 2 is the preferred alternative and the
most appropriate wastewater management program for the residents of Orange
County.
Section 2: That the proposed project, which consists of a 30-year
Collection, Treatment and Disposal Facilities Master Plan, will create a number
of significant or potentially significant environmental effects. These impacts
are identified with a "P" or "PS", respectively, in Tables S-2 (Treatment
Scenario No. 2) and S-3 of the Final Program EIR, that are appended to this
Resolution as Attachments A and B.
-2-
"'' :'.
Section 3: That the Boards of Directors of DISTRICTS do further find that
changes or alterations have been required in, or incorporated into, the proposed
project which avoid or substantially lessen significant environmental effects,
as identified in the Final Program EIR.
Section 4: Significant impacts identified in the Final Program EIR that
will be mitigated to less-than-significant levels by the DISTRICTS are as
follows:
TREATMENT AND DISPOSAL -SCENARIO NO. 2
A. Degradation of the infaunal community area by solids in effluent
will be mitigated by spatial separation between existing and proposed outfalls.
B. Safety hazards during operations will be mitigated by conducting
safety classes, using appropriate safety equipment, and enclosing facilities.
c. Risks of workers contacting pathogens will be mitigated through
implementation of a safety program.
D. Temporary loss of use of a bicycle trail along the Santa Ana
River during interplant pipeline construction will be mitigated by relocation of
the bicycle trail during construction.
E. Temporary visual impacts during interplant pipeline construction
will be mitigated by minimizing construction time and post-construction
restoration.
F. Conflicts between treatment plant facilities and residential land
uses will be mitigated by maintaining a visual buffer.
-3-
'.
G. Increased congestion from construction vehicles will be mitigated
by appropriate scheduling of construction and coordinating with the ·Cities of
Fountain Valley and Huntington Beach.
H. Increased congestion from operations vehicles will be mitigated
by the DISTRICTS 1 implementing a ride-sharing program for their employees and
scheduling sludge hauling and chemical delivery trucks to stay off regional
facilities during peak commute periods to the extent feasible.
I. Temporary construction noise, and pile-driving noise and
vibration, will be mitigated by limiting construction hours, using alternative
foundation designs, informing the neighbors of construction activities, and
hiring an acoustics engineer to evaluate a means of buffering external noise
emanating from construction sites.
j. Noise impacts caused by engines during operations at treatment
facilities will be mitigated with mufflers and by enclosing engines.
K. Air emissions from wastewater, plant equipment, vehicles, and
sludge during project operations will be mitigated by continued compliance with
SCAQMD requirements, continuation of the DISTRICTS 1 source control program, and
enclosing treatment plant facilities.
L. Odors caused by plant operations, sludge disposal, and
reclamation plants will be mitigated by continuing the DISTRICTS 1 current odor
control program, covering certain plant pracesses, and using rural sites for
sludge disposal where feasible.
M. Exposure of the treatment plants to flooding will be mitigated by
maintaining a flood wall at the plants and instituting a disaster preparedness
plan.
-4-
N. Disruption of treatment reliability provisions during
construction will be mitigated by appropriate construction scheduling and by
providing for treatment redundancy.
TRUNK SEWER CONSTRUCTION
o. Access, noise, and dust impacts during construction will be
mitigated by scheduling construction for off-peak traffic hours where feasible,
compliance with all applicable noise ordinances, and water spraying of dry earth
to the extent feasible.
P. Land use impacts caused by construction of Orange Park Acres
Trunk on properties adjacent to Handy Creek will be mitigated by providing
advance notification of construction and scheduling dates.
Q. Land use impacts caused by construction of Big Canyon Trunk on
Big Canyon Country Club, and impacts of constructing Los Alamitos Subtrunk
parallel sewers on Forest Lawn Memorial Park, will be mitigated by using "inside
the pipe" repair and rehabilitation techniques, and by appropriate scheduling of
construction to the extent feasible.
R. Disruption of roadways and bikeways during construction will be
mitigated through preparation of traffic control plans that maintain maximum
safe traffic access.
S. Disruption of util·ity ~ervice during excavation activities will
be mitigated by coordinating with the Underground Service Alert and local
utilities, developing plans for alternative services where needed, and rerouting
of facilities where necessary and at the DISTRICTS' expense if a utility
purveyor has prior rights.
-5-
T. Increased emergency response times during project construction
will be mitigated by preparing traffic control plans prior to construction and
by notifying emergency service provides before construction schedules are
implemented.
u. Any disturbance of drainage facilities during project
construction, and groundwater infiltration into open trenches and tunnels, will
be mitigated by scheduling sewer construction during dry months, coordinating
with Orange County Flood Control District to protect underground facilities and
determine best scheduling, and pumping and discharging groundwater pursuant to
the DISTRICTS' NPDES permit.
V. Disturbance of cultural resources along Handy Creek during
construction of Orange Park Acres Trunk Sewer will be mitigated by halting work
if unusual materials are found, and then consulting qualified professionals to
examine the materials, record findings, and properly curate any significant
artifacts discovered.
w. Dust generation and air pollutant emissions from construction
vehicles will be mitigated by using watering trucks as necessary to control dust
and clean vehicles and keeping streets free of dust and dirt, covering trucks
and dirt piles, using well-tuned and properly-maintained construction equipment,
and discontinuing construction during second-stage smog alerts to the extent
feasible.
X. Impacts of Orange Park Acres Trunk Sewer construction on
equestrian trails and bridges will be mitigated by designing and constructing
the sewer to avoid removal of equestrian bridges and, if necessary and feasible,
developing an alternative equestrian trail around construction activities.
-6-
Y. Impacts of replacement of Big Canyon Tr~nk Sewer on Big Canyon
County Club Golf Course will be mitigated by scheduling construction during
winter to avoid periods of peak use, to the extent possible.
Section 5: For the following significant impacts, either no feasible
mitigation measures are available, or the DISTRICTS will implement certain
feasible mitigation measures, but residual impacts will still be significant or
potentially significant. For these impacts, specific economic, social or other
considerations make infeasible other mitigation measures or alternatives that
may have been identified in the Final Program EIR.
TREATMENT AND DISPOSAL -SCENARIO NO. 2
A. Impacts of outfall construction on the least tern colony will be
partially mitigated by scheduling construction to avoid any nesting disturbance,
conducting additional enviroomental studies, and consulting with the U.S. Fish .
and Wildlife Service under Section 7 of the Endangered Species Act. A
project-specific EIR will be prepared for outfall construction. This impact
could be avoided by the No-Project Alternative, but the No-Project Alternative
is considered infeasible because it would lead to a decline in treatment
effectiveness, risk violations of effluent quality standards, exceed the
capacity of the existing 120-inch diameter ocean outfall and violate NPDES
permit conditions.
B. Construction safety hazards to workers and the public will be
partially mitigated by continued implementation of a safety program, fence
construction, and coordination with cities. This impact could be avoided by the
No-Project Alternative, which is considered infeasible for the reasons stated in
Section 5A.
-7-
C. Chemical spill risks during handling and transport will be
partially mitigated by continuing a safety program, fence construction,
coordination with cities, and conformance to U.S. Department of Transportation
transport standards.
D. Temporary loss of beach use during outfall construction cannot
feasibly be mitigated. This impact could be avoided by the No-Project
Alternative, which is considered infeasible for the reasons stated in Section
5A.
E. Temporary outfall construction aesthetic impacts on Huntington
State Beach and Newport Beach can be partially mitigated by minimizing
construction time and by post-construction restoration. This impact could be
avoided by the No-Project Alternative, which is considered infeasible for the
reasons stated in 5A.
F. Land use impacts associated with sludge disposal (land
requirements of 410 acres for monofill or 580 acres for dedicated land disposal)
cannot feasibly be mitigated. Impacts on the landfill capacity of sludge
co-disposal in landfills cannot feasibly be mitigated. As identified in the
Final Program EIR, these impacts could be mitigated by minimization of total
sludge volume and reuse of all sludge, but such reuse is not feasible under
current conditions, because of limited markets for sludge products and
regulatory health and safety issues that need to be resolved.
G. Air quality impacts associated with construction dust, equipment
emissions, and truck emissions will be partially mitigated by controlling dust,
limiting work during first-stage smog alerts, and requiring contractors to
-8-
maintain equipment, and where feasible schedule deliveries to avoid peak traffic
periods and implement ride-sharing programs. These impacts could be avoided by
the No-Project Alternative, which is considered infeasible for the reasons
stated in SA. These impacts could also be avoided by Treatment Scenario No. 1,
which is considered infeasible because it would lead to treatment levels below
those currently being implemented.
H. Emissions of air toxics will be partially mitigated by continued
compliance with SCAQMD requirements and source reduction.
I. Exposure of the treatment plants to seismic action can be
partially mitigated by design and maintenance of the plants to code and best
engineering practice, and by maintaining an emergency preparedness plan.
J. Energy use and construction material consumption during project
construction, and energy use during project operation cannot feasibly be
mitigated. The No-Project Alternative could avoid energy and construction
material impacts during project construction, but is considered infeasible for
the reasons stated in Section SA.
TRUNK SEWER CONSTRUCTION
K. Increases in emergency response times by police, fire, and
paramedics will be partially mitigated by preparation of traffic control plans.
This impact could be avoided by the No-Project Alternative, which is considered
infeasible because of public health and water quality problems that would result
from its implementation.
L. Water quality effects caused by stormwater runoff from soil
stockpiles will be partially mitigated by covering soil stockpiles during winter
-9-
if necessary. Damage to sewer facilities during seismic events, and resulting
water quality effects of line rupture or blown manholes, will be partially
mitigated by adherence to standard sewer design and construction practices.
These impacts could be avoided by the No-Project Alternative, which is
considered infeasible for the reasons stated in Section 5A.
Section 6: For the following significant impacts identified in the Final
Program EIR, project-changes or alterations that would avoid or substantially
lessen impacts are within the responsibility and jurisdiction of another public
agency, and not the DISTRICTS. Such changes have been adopted by such other
agency, or can and should be adopted by such other agency.
A. Water quality impacts from leachate generated by landfills where
sludge is disposed can be mitigated by having the landfill operating agency
install a leachate collection system and monitoring program, as well as
continuing the DISTRICTS 1 source control program.
B. Risk of exposure to toxic materials from sludge and leachate can
be mitigated by having the landfill operating agency institute a safety program,
a leachate collection system, and a monitoring program, and by practicing daily
landfill cover.
c. Traffic congestion and delay due to growth can be partially
mitigated by implementation of Southern California Association of Governments•
(SCAG 1 s) Growth Management Plan and Regional Mobility Plan, and by local
governments improving jobs/housing balance.
D. Vehicle emissions increases from growth can be partially
mitigated by implementation of SCAG 1 s Growth Management Plan and SCAQMD 1 s Air
Quality Management Plan.
-10-
E. Loss of flood storage capacity at the Crescent Basin reclamation
plant site can be mitigated by incorporating alternative designs to allow
continued use of land as a flood basin or by providing flood storage elsewhere.
F. Increased demand for all public services and utilities due to
growth can be partially mitigated by service agencies and utilities planning to
meet increased demand.
G. Population and employment increases facilitated by trunk sewer
construction, and resulting secondary environmental effects, can be partially
mitigated by land use planning, growth management, and environmental protection
measures that are the responsibility of SCAG, SCAQMD, and local governments.
H. For those impacts identified in Sections 6C, 6D, 6F and 6G,
post-mitigation residual impacts will still be significant and cannot feasibly
be mitigated.
Section 7: The DISTRICTS will implement the following mitigation measures
for impacts identified as less than significant in the Final Program EIR.
A. Marine environment impacts of suspended solids, toxics, and
metals will be mitigated by continued implementation of the DISTRICTS 1 source
control program.
B. Marine environment impacts of coliform bacteria and viruses will
be mitigated by disinfection upon pipeline breakage or identification of a
health risk.
C. Remote risk of pathogen contact by beachgoers will be mitigated
by ocean monitoring, disinfection upon pipeline breakage, and conducting
sanitary surveys and other studies to investigate pathogen sources and risks.
-11-
o. Aesthetic impacts of construction and plant equipment will be
mitigated by additional screening.
E. Increased demand for potable water in treatment plants will be
mitigated by using reclaimed wastewater where possible, and promoting water
conservation.
F. Cultural resources impacts during construction at the treatment
plants will be mitigated by consulting an archeologist if artifacts are
encountered.
G. Biological impacts of construction of Orange Park Acres Trunk
Sewer within Handy Creek will be mitigated by routing the sewer along the top of
creek banks or nearby streets, or if construction proceeds in Handy Creek, by
preserving some major mature trees and replanting creek banks with suitable
vegetation.
H. Temporary impacts on traffic access to beach recreation areas
will be mitigated by traffic control plans that maintain maximum access.
Section 8: The DISTRICTS hereby adopt the following monitoring and
reporting program to ensure implementation of the mitigation measures described
in Sections 4, 5 and 7.
A. Within 30 days following adoption of this resolution, the General
Manager, or his designee, shall appoint an Environmental Monitor responsible for
coordinating mitigation monitoring and reporting activities.
B. ·The Environmental Monitor shall review the design of all Master
Plan facilities and either certify that the facility design complies with EIR
-12-
migitation measures, or reconrnend to the Director of Engineering design
modifications necessary to achieve such compliance. In addition, prior to the
DISTRICTS obtaining bids for construction .of Master Plan facilities, the
Environmental Manager shall review the bid documents and certify compliance with
applicable mitigation measures.
C. Within 60 days of the adoption of this resolution, the
Environmental Monitor shall design a checklist to demonstrate compliance with
mitigation measures in the field during construction of Master Plan facilities.
The Director of Engineering shall assign staff responsibilities for completing
this checklist, and certify compliance with mitigation measures during and after
construction of Master Plan projects.
D. The Director of Engineering shall prepare reports to the General
Manager on the status of mitigation ~easure implementation.
Section 9: The Boards of Directors of County Sanitation Districts Nos. l,
2, 3, 5, 6, 7, 11, 13 and 14 of Orange County, California, have balanced the
benefits of the Master Plan against its unavoidable environmental risks in
determining whether to approve the Master Plan. The Boards hereby find that the
occurrence of the unavoidable significant environmental effects identified in
the Final Program EIR and listed in Sections 5 and 6 is acceptable for the
following reasons:
A. The Master Plan is necessary to ac_commodate wastewater flows from
ongoing development approved by local governments after required environmental
reviews. The DISTRICTS are a single-purpose agency with the responsibility to
collect, treat and dispose of wastewater generated with the DISTRICTS' service
area.
-13-
B. The Master Plan is necessary to meet the following objectives:
to provide an environmentally sound regional se~age collection, treatment and
disposal system that minimizes risks to public health and safety; to protect the
beneficial uses of water, land, and air from significant impairment from
wastewater management activities; to comply with all federal and state
regulatory standards applicable to the treatment reuse and disposal of treated
effluent and sludge; to encourage wastewater flow reduction through water
conservation and reuse; to reclaim wastewater for beneficial reuse and encourage
development of markets for reclaimed wastewater; and to encourage beneficial
reuse of sludge.
Section 10: That the treatment alternative described as Scenario No. 2 is
the preferred alternative.
Section 11: That the Board Secretary is authorized and directed to file
the Notice of Determination and any other documents in accordance with the
requirements of CEQA and the Districts• CEQA procedures.

Environmental Impacts
In general, temporary (short term) reduced
access to private and public properties, localized
noise and fugitive dust increases during con-
struction.
Property owners adjacent to affected portion of
Handy Creek would suffer construction impacts
through yards abutting the creek, during con-
struction of the Orange Park Acr~s Trunk. ·
Portion of the private Big Canyon Country Club
will be excavated and unusable while
replacement of Big Canyon Trunk underway.
Construction of Los Alamitos Subtrunk parallel
sewers through Forest Lawn Memorial Park
will impede access along private streets and
disrupt the quiet atmosphere.
If Air Basin Trunk No. 2 rehabilitation through
the Harbor Lawn Memorial Cemetery and
nearby C. W. Tewinkle School is done by
trenching, both of these sites would be tem-
porarily impacted by excavation and related
construction noise, vehicles, and equipment.
Proposed improvements would facilitate popula-
tion and employment increases, in accordance
with adopted local general plans. Secondary
effects on air quality, water quality, transporta-
tion, biological resources, cultural resources,
utilities, public services, energy, natural
resources, noise, and solid waste management
would result from such growth.

Environmental Impacts
Numerous roadways and bikeways will be
temporarily disrupted during construction
activities involving pipeline trenching or man-
hole and pump station repair. Such impacts
will be most severe along heavily traveled streets
and where the roadway width and configuration
prevents simple detouring or maintenance of
two-way traffic.
Emergency response times by police, fire, and
paramedics could be increased.
Numerous underground and overhead facilities
could be disturbed or rerouted during construc-
tion involving trenching or other excavation.
Such disturbances could result in temporary loss
of service to utility customers.

Traffic control plans will be prepared

coordination with Caltrans and all local
agencies responsible for the affected
circulation routes will occur in the
preparation of these plans.

The Sanitation Districts will coordinate
project design and construction with the
Underground Service Alert of Southern
California and all local utility purveyors
lo determine the precise locations of all
potentially affected utility facilities and
to develop plans for alternate service, if
needed. Facilities that must be rerouted
will be done at CSDOC's expense if the
particular utility purveyor has prior

Environmental Impacts
Temporary (short-term) access restnct1ons
during project construction could increase
emergency response times for policy, fire, and
paramedic services. Secondary impacts due to
increased population, housing, and employment
will include need to expand public services
(schools, fire, police, medical, library, transpor-
tation, solid waste management, waler and air
quality management, general government).
Construction of Orange Park Acres Trunk
within Handy Creek would destroy existing
vegetation, resulting in destruction of local
wildlife habitat as well. Several creek bolloms,
lightly covered with scallered grasses, will be
disturbed, temporarily disrupting birds and
mammals in those areas. No rare or endan-
gered species are.found in any project area.
Numerous existing drainage facilities will be
crossed or lie in close proximity to proposed
sewer improvements. Storm water runoff could
be impeded if such facilities are disturbed during
the rainy seasons. Open trenches and tunnels
may be subject to groundwater infiltration, which
will need to be discharged properly.
Excavated soil materials could degrade quality
of downstream waters if stockpiles are washed
off by storm waters into nearby catch basins.
Line rupture or blown manholes resulting from
seismic events could result in discharge of raw
sewage into underground or downstream waters.

Mitigation Measures
Preparation of traffic control plans prior
to construction. Provide advance notifi-
cation of construction schedule to emer-
gency service providers. Mitigation of
growth-induced secondary impacts dis-
cussed in Part 2, Chapter 9.
Route Orange Park Acres Trunk along
top of creek banks or along nearby
streets. If this sewer is constructed in
Handy Creek, preserve some major
mature trees and replant creek banks
with suitable vegetation to replace lost
wildlife habitat.
Scheduling sewer construction during
dry months. Coordination with Orange
County Flood Control District to protect
underground facilities, determine best
scheduling. Groundwater will be
pumped and discharged pursuant to the
Sanitation Districts' NPDES permit.
Soil stockpiles will be covered during
winter months. Adherence to standard
sewer design and construction practices
will minimize potential raw sewage
discharge due to line rupture or man-
hole blowout.

Construction of the Orange Park Acres Trunk
could temporarily disrupt the equestrian trail
along Orange Park Boulevard. It could also
require temporary removal of the existing
pedestrian/equestrian bridge across Handy
Creek at Orange Park Boulevard and possibly
the planned bridge at Meads Avenue.
Replacement of the Big Canyon Trunk will
temporarily prevent use of about one-fourth of
the Big Canyon Country golf course.
Disruption of traffic along Pacific Coast High-
way and nearby roadways that lead to the coastal

The Sanitation Districts will attempt to
design and construct the Orange Park
Acres Trunk in a manner which does not
require a temporary removal of the two
bridges over Handy Creek. This may
include an alternate alignment which
follows existing streets'. If necessary and
fe~sible, an alternate equestrian trail will
be developed around the construction
activities. The Sanitation Districts will
consult with the Orange Park Acres
