Public Scoping Meeting for the

1

• Public Scoping Meeting for the
• Preparation of a
• Program Environmental Impact Report
• to Address Implementation of the
• Optimum Basin Management Program (OBMP) for the
  Chino Groundwater Basin

2
Optimum Basin Management ProgramPurpose of a
Scoping Meeting

• Scoping helps to identify the range of actions,
  alternatives, environmental effects, methods of
  assessment, and mitigation measures to be
  analyzed in depth, and eliminates from detailed
  study those issues that are not important to the
  decision at hand (Section 15083 CEQA Guidelines).

3
Optimum Basin Management ProgramPurpose of
Notice of Preparation (NOP)

• The purpose of a NOP is to fulfill legal
  notification requirements, and to inform the
  public and CEQA Responsible and Trustee Agencies
  that a program EIR will be prepared.
• The intent is to solicit input regarding the
  potential environmental effects of the proposed
  project.

4
Optimum Basin Management ProgramProgram
Environmental Impact Report (EIR)

• A program EIR has been selected for the OBMP
  based on the definition of a program document
  contained in Section 15168 of the State CEQA
  Guidelines which states
• A program EIR is an EIR which may be prepared
  on a series of actions that can be characterized
  as one large project and are related either (1)
  Geographically, (2) As a logical part in the
  chain of contemplated actions,...

5
Optimum Basin Management Program CEQA

• The OBMP clearly establishes a program that
  falls within the scope of a programmatic document
  because it defines a series of actions that are
  tied together within the Chino Groundwater Basin
  and the proposed program actions are all designed
  to fulfill the goal of enhanced safe yield and
  improved water quality for the Basin.

6
Optimum Basin Management ProgramPotential
Environmental Effects

• The IEUA proposes to prepare a full scope
  environmental evaluation that will address all
  issues on a standard Initial Study Environmental
  Checklist Form. These include
• Land Use ? Hazards
• Population Housing ? Noise
• Geological Problems ? Public Services
• Water ? Utilities Service Systems
• Air Quality ? Aesthetics
• Transportation/Circulation ? Cultural Resources
• Biological Resources ? Recreation
• Energy Mineral Resources

7
Optimum Basin Management ProgramPotential
Impacts Requiring Mitigation

• Geological problems (subsidence or liquefaction)
  may be caused or exacerbated due to extraction
  and recharge of groundwater in support of OBMP
  objectives.
• Biological resource impacts may be caused by
  ground disturbance undertaken to install the
  facilities required to implement the OBMP.
• The creation and expansion of water-related
  facilities may affect future growth in
  undeveloped areas.

• Recycling reclaimed water has the potential to
  increase levels of Total Dissolved Solids and
  adversely impact groundwater quality in the
  Basin.
• Operation of desalting and treatment facilities
  will generate salt and other waste products that
  may be problematic for disposal.
• Construction of additional facilities has the
  potential to conflict with existing land uses.

8
Optimum Basin Management ProgramPotential
Impacts Requiring Mitigation

• The unplanned use of flood control basins for
  percolation of storm water and recycled water
  could result in the potential for exposure of
  people and surrounding areas to flooding hazards.
• Treatment of degraded water has the potential to
  generate hazardous wastes (both solid waste and
  air pollutants) and the potential to expose
  people to hazardous conditions.
• Visual resources may be affected by construction
  of element facilities.

• Construction and operation of facilities to
  implement program elements may have air quality
  impacts (fugitive dust or other emissions).
• Construction activities and new facility
  operations may generate noise that will conflict
  with adjacent land uses.
• Cultural resource impacts may be caused by ground
  disturbances undertaken to install OBMP physical
  facilities.

Chino Basin Watermaster Optimum Basin Management
Program

• The Optimum Basin Management Program (OBMP)
  encompasses the Chino Basin. The Chino
  Groundwater Basin has been divided into five
  management zones, based on hydrologic conditions,
  and into three sub-basins.

Optimum Basin Management ProgramCharacteristics

• The Chino Groundwater Basin is one of the largest
  groundwater basins in southern California,
  containing about 5 million acre-feet of water in
  storage with an additional unused storage
  capacity of about 1 million acre-feet.

14
Optimum Basin Management ProgramCharacteristics

• Cities and other water supply entities produce
  groundwater for all or part of their municipal
  and industrial supplies from the Chino
  Groundwater Basin.
• The average annual well production is 140,000
  acre-feet for the Basin.
• An additional 300 to 400 agricultural users also
  produce groundwater from the Basin.

15
Optimum Basin Management ProgramDescription

• The Chino Basin Watermaster was effectively
  established by a Judgement entered in the
  Superior Court of California (the Court) in 1977.
• The Judgement allows the Watermaster to collect
  funds, to finance essential studies and
  negotiations, and to implement a management
  program for the Chino Groundwater Basin.
• The Watermaster was also directed by the Court to
  prepare and submit an OBMP document.

16
Optimum Basin Management ProgramPhasing

• Phase 1- Defining the state of the Chino
  Groundwater Basin, establishing goals concerning
  major stakeholders and affirming the management
  plan.
• Phase 2- Implementation mechanisms for the OBMP.

17
Optimum Basin Management ProgramGoals

• Goal 1 To enhance Chino Basin groundwater
  supplies.
• Goal 2 To protect and enhance water quality.
• Goal 3 To enhance management of the Chino
  Groundwater Basin.
• Goal 4 To equitably finance the OBMP.

  Program
• Element No. 9 Conjunctive-Use Programs

19
Program Element No. 1

• Develop and Implement Comprehensive Monitoring
  Program

• Impact of recharge water on groundwater will be
  monitored using up down gradient monitoring
  wells.
• Data from the monitoring study will provide
  necessary information to determine outflow to the
  Santa Ana River, actual Basin production, optimum
  groundwater treatment facility design and
  management policies for the Basin.

20
Program Element No. 2

• Develop and Implement Comprehensive Recharge
  Program

• The recharge of recycled water will be
  coordinated with percolation of surface runoff
  from the mountains, urban stormwater runoff, and
  State Water Project sources, so as to minimize
  future dependency on uncertain water supplies.
• Locate new recharge facilities in the upper half
  of the basin to ensure recovery of this water for
  beneficial uses and to increase basin yield.
• Locate new recharge facilities in the lower half
  of the basin only when recovery of recharged
  water can be assured, and when sub-basin water
  quality will not be adversely affected (Relates
  to Program Element 3,4,5,9).

21
Program Element No. 3

• Develop and Implement Water Supply
  Plan for the Impaired Areas of the Basin.

• Develop regional and local groundwater treatment
  systems/programs to treat degraded groundwater
  for subsequent direct beneficial uses, to improve
  groundwater quality by decreasing TDS and
  Nitrogen concentrations, and to maintain/increase
  safe yield.
• These systems/programs will help to prevent basin
  outflow, stop the spreading of degraded water
  quality, and improve Santa Ana River water
  quality (Related to Program Elements 1,5,7,9).

22
Program Element No. 4

• Develop and Implement Groundwater
  Management Plan for Management Zone 1.

• Develop groundwater level and quality management
  programs for use in arresting the decline in
  groundwater level for this zone.
• Implement a combination of the following actions
  to minimize potential for additional subsidence,
  fissuring, lost production capability and water
  quality problems (a)increase recharge, (b)manage
  zonal production, (c)increase direct use of
  supplemental water supplies in this area, and (d)
  develop new management policies regarding cyclic
  and local storage accounts (Relates to Program
  Elements 1,2,5,6,8,9)

23
Program Element No. 5

• Develop and Implement Regional
  Supplemental Water Program.

• To allow for greater recharge of recycled water,
  develop offset programs and mitigation programs
  to increase the assimilative capacity for TDS and
  Nitrogen in the Basin.
• As future demands increase, traditional sources
  of supplemental supplies may become limited. By
  maximizing the direct use of recycled water,
  future dependence on expensive and less reliable
  sources will be minimized.
• This program will ensure that adequate supplies
  of high quality water will be available to meet
  future demands (Relates to Program Elements
  2,3,4,9).

24
Program Element No. 6

• Develop and Implement Cooperative Programs with
  the Regional Board and Other Agencies to Improve
  Basin Management.

• Cooperatively participate in RWQCB Watershed
  Management Efforts for the region.
• Coordinate efforts to blend recycled water,
  imported water and natural storm water,
  facilitating better management of the TDS and TIN
  in flushing/cleaning-up the groundwater basin.
• Coordinate with regulatory agencies to share
  monitoring responsibilities and to facilitate
  information distribution so that coordinated
  action may be taken to define and address water
  quality issues, and to allow for improved
  timeliness in clean-up efforts (Relates to
  Program Elements 1,3,4,9).

25
Program Element No. 7

• Develop and Implement Salt Management
  Program.

• Develop salt budget goals to obtain optimum water
  quality for the entire Chino Basin.
• Coordinate recycled water recharge program with
  the construction of desalters in the lower end of
  Chino Basin.
• Develop programs to export manure, treat or
  export dairy sewage, and eliminate dairy sewage
  discharge into the basin. These actions will
  decrease ongoing salt and nitrogen loading at
  less cost than treatment of receiving waters.

26
Program Element No. 8

• Develop and Implement Groundwater
  Storage Management Program.

• Develop methods to account for losses from cyclic
  and local storage accounts and set limits on
  storage.
• This action will help maintain the safe yield and
  ensure that basin water is put to maximum
  beneficial use (Relates to Program Element 4).

27
Program Element No. 9

• Develop and Implement
  Conjunctive-Use Program.

• Develop conjunctive use programs that account for
  water quantity and quality and will result in
  balanced production throughout the Basin.
• This will result in lower water supply costs to
  basin producers (Relates to the implementation of
  all Program Elements and Goal Number 4).

28
Optimum Basin Management ProgramPotential
Projects

• Maintain and construct wells as necessary for
  monitoring and recharge purposes
• Install water pipelines and brine pipelines to
  deliver water, transport recycled water and
  export wastes to the SARI system
• Construct Pump Stations
