         Acronym Definitions
 OWTS
    Onsite Wastewater Treatment Systems. The
     most common type of OWTS is a septic
     system, consisting of a septic tank and
     leachfield.
 TMDL
    Total Maximum Daily Load is a plan adopted
     by a Regional Water Board to limit pollutants
     reaching an impaired water body and return it
     to its full beneficial uses.

                                                     5
OWTS Policy and the Water Code
   13291. (a) On or before January 1, 2004, the state
    board, (in consultation with…) shall adopt regulations or
    standards for… :
   (1) Any system that is constructed or replaced.
   (2) Any system that is subject to a major repair.
   (3) Any system that pools or discharges to the surface.
    (4) Any system that, in the judgment of a regional board
    or authorized local agency, discharges waste that has
    the reasonable potential to cause a violation of water
    quality objectives, or to impair present or future
    beneficial uses of water, to cause pollution, nuisance, or
    contamination of the waters of the state.

                                                                 6

                      9
    Proposed Regulatory Framework
 Tier Zero: Existing OWTS that are functioning
properly and are not adjacent to septic polluted
surface waters
 Tier One: New or replaced OWTS that meet low-risk
  siting and design criteria
 Tier Two: New or replaced OWTS covered by a
  Local Agency Management Program
 Tier Three: New and existing OWTS associated with
  impaired water bodies and septic polluted surface
  waters
 Tier Four: Existing OWTS requiring Corrective
  Action
                                                  10
       Tier 0 – Existing OWTS
 Up  to 10,000 gallons per day
 Domestic strength wastewater, or high
  strength allowance for food service
  buildings with a grease interceptor
 Functioning as designed with no surfacing
  effluent
 Does not meet conditions set forth in Tier
  3 or Tier 4

                                           11
        Tier 1 – New OWTS
 For  OWTS not covered by a Local Agency
  Management Program
 Not included in Tier 2 or 3
 3,500 gallons per day max size
 Can use percolation rate or soil type basis
  for sizing



                                            12
              Tier 2 – New OWTS
   Local Agency Management Plan
       Differing system design requirements;
       Differing siting controls such as system density and setback
        requirements;
       Requirements for owners to enter monitoring and maintenance
        agreements; and/or
       Creation of an onsite management district.
 10,000 gallons per day max size
 Watershed based monitoring of groundwater
  and surface water quality for OWTS impacts
  done by local agency
                                                                       13
 Listing Impaired Water Bodies
 On going monitoring performed on surface
  water bodies
 Data solicitation period for outside data
 Data analysis
     May be for listing or removing from list
        decision staff recommendation
 Listing
  based on data and Listing Policy


                                                 14
 Listing Impaired Water Bodies
 Impaired water bodies list is then
  considered in a public process by:
     Regional Water Board
     and then State Water Board
     and then U.S. Environmental Protection
      Agency who finally approves
 Listing   cycle runs about every two to four
  years

                                                 15
    Tier 3 – New and Existing OWTS
   TMDL is the key, its implementation program
    will:
       Establish what is required for existing and new OWTS
       Establish which locations are included, and
       Establish the schedule for each required action.
   Management is collaborative effort between
    local agency and Regional Water Board




                                                          16
    Tier 3 – New and Existing OWTS
   OWTS by specifically identified pathogen and
    nutrient impaired water bodies:
       Wait 5 years for TMDL or assessment
       Or if no TMDL, upgrade to advanced treatment if in
        100/600 foot rule
       Extra time allowed if agreement to hook up to sewer
        system
   For new systems near all pathogen and nutrient
    impaired water bodies:
       Setbacks in Tier 1 apply, and
       Within 600 feet needs advanced treatment until a
        TMDL is completed.
                                                              17
                 TMDL Example
   San Lorenzo River Watershed Nitrate and
    Pathogen TMDL
       Identifies OWTS as source
       Allocates a loading
       Has a specific implementation program and schedule
   Lake Elsinore and Canyon Lake TMDL
       Identifies OWTS as source
       Allocates a loading
       Requires local agency to develop a Septic System
        Management Plan that is consistent with the future
        OWTS Policy

                                                             18
      Tier 4 – Existing OWTS
 Corrective Action – fix what is broken
 Meet Tier 1, 2, or 3 requirements as
  appropriate for components being repaired
 Local agencies have discretion within their
  Tier 2 programs to have repairs be in
  substantial conformance, to the greatest
  extent practicable
 OWTS found to be impacting drinking water
  or other uses must be modified or upgraded
  per requirements
                                                19
              Financial Aid
 Is available from State Water Board for
  local agencies to have an assistance
  program within their jurisdiction, but is at
  their option
 Provides low interest loans
 See “Resources for Local Agencies” on
  website for more details
