Background

• Long-standing permit exemption for
  Agricultural Sources under the State law
• Federal law requires permits for major
  agricultural sources (Title I and Title V)
• Federal sanctions (entire state) set for
  November 2003 unless ag exemption
  removed
• SB 700 (Florez) -- Signed into Law in
  9/2003
SB 700 Summary

• Removes permit exemption for Agricultural
  sources (major and minor sources)
• Requires Particulate Matter (PM) controls
  (including PM precursors)
• Additional pollution controls and permits
  for Confined Animal Facilities (CAFs)
• Offers off-ramps from pollution control and
  permitting
• Treat agricultural facilities similar to other
  air pollution sources
SB 700 Control Requirements

• BACM and BARCT for sources where
  technology is transferable
• Controls for tilling, discing, cultivation,
  and raising of animals
• Controls for fugitive emissions
• Include measures for PM precursors
• Enforceable rules and regulations
 Minimum Permitting Requirements

• Major agricultural sources will be subject to
  Title V and NSR requirements
• District MUST require permits for agricultural
  sources with emissions at or above ½ the
  major source thresholds unless certain
  findings are made at a public hearing
• District CANNOT require permits for sources
  with emissions below ½ major source
  thresholds unless certain findings are made at
  a public hearing
Permitting Offramp
• District may exempt a source if:
   • Replace I.C. engines with electrical or
     State/EPA certified, and
   • Mitigate emissions from all ag activities,
     and
   • Mitigate emissions from all ag equipment
• May serve as an incentive that could lead
  to air quality benefit
 More Requirements for CAFs

• 7/1/05 - CARB to define “Large”
  CAFs
• 7/1/06 – District to adopt permitting
  and mitigation rules for “Large CAFs”
• Degree of control = BARCT
• Regulations must be submitted to
  EPA for inclusion in the SIP
 More Requirements for CAFs (cont.)

• 1/1/07 - “CAF permit” applications due
  from “large” CAFs
• District issue permits within 6 months
  (30-day public notice) Sources to
  implement mitigation within 1 year
• NOT a substitute for other permitting
  requirements
  Permitting Timeline
• Ag. exemption goes away 1/1/2004
• Existing sources:
  – Local permit applications due by 7/1/04
  – Title V permit applications due 1/1/05
  – Grandfathered (no BACT/ERCs)
  – BARCT/BACM later
• New sources (e.g., new dairies):
  – Effective 1/1/04 must obtain construction
    permits subject to BACT,ERCs, and public
    review
              BACT Process

• Find the most effective control that is:
  – Technologically feasible
  – Cost effective/Achieved in practice
• Work with industry groups, individual
  dairies, equipment vendors
• Public workshops
• Evolve with time and science
     Areas of Possible Dairy Controls
     and/or Practices
•   Milking Center
•   Cow Housing/Feeding
•   Manure Storage Piles
•   Land Application of Waste Material
•   Lagoons
    Number of affected sources
• Total number of facilities in the Valley:
  – Farms (~28,000)
  – CAFs (~5,500)
• Facilities subject to BARCT/BACM:
  – Farms (~8,000)
  – CAFs (~1,100)
• Facilities subject to permits
  – Farms (~4,000)
  – CAFs (~350)
  – Fewer sources may be affected after closer
    examination
Rule 4550
Conservation Management Plans

• Conservation Management Plans for Ag
  Sources
• Implement Controls for On-field
  Activities
• Similar to Permitting – but it’s Not
  Permitting
• Sources Select from Control Options
CMP Program Concept
• Mandatory participation for farm sites 100
  contiguous acres and larger
• Select 1 measure from each of 5 categories
     –   Land preparation/cultural activities
     –   Harvest
     –   Unpaved roads
     –   Unpaved parking and staging areas
     –   Other – wind erosion prevention, waste
         burning
• Relatively simple plans submitted to NRCS/RCD
  for review and to District for approval
CMP Program
• Practices proposed by growers to be
  provided in a handbook
• Growers can propose new measures for
  Ag Tech Committee review & District
  approval
• New and improved CMPs as technology
  develops over time
• Best Available Control Measures (BACM)
• Help achieve annual 5% reduction in PM
  emissions
CMP Examples
• Practices that reduce or eliminate the need to
  disturb the soil or manure
• Practices that protect the soil from wind erosion
• Equipment modifications to physically produce
  less PM10
• Applying water or dust suppressants to reduce
  emissions entrained by moving vehicles and
  equipment
• Reducing speed or access on unpaved roads
  and parking areas
• Alternative practices to waste burning
CMP Timeline
• Rule development now underway
• Final workshops in March 2004
• Rule adoption May 2004
• Outreach/education ongoing
• CMP Program implementation begins July
  2004
• CMP Plans due no later than December 31,
  2004
• Fees to cover plan program costs with 50%
  discount for NRCS verification
Ag Research Priorities
• Dairy and other CAFO VOC emission
  factors – eventually need process based
  factors
• CAFO ammonia and PM10 emission
  factors
• On field management practice PM10
  emission differentials
• Equipment modifications to reduce PM10
  emissions
 Ag Program Implementation
• Extensive outreach – Coordination with Industry
  Groups
• Small Business Assistance
• User-friendly application forms
• Web-based tools/aides
• Development of good science and staff expertise
• Coordination/Utilization with other agencies (e.g.,
  NRCS, County agencies)
• Support legislation aiding effective
  implementation (e.g., Eliminate utility stand-by
  charges)
• Statewide coordination

Amendments to Rule 4103
(Ag Burning)
By June 1, 2005, the District shall
  develop and adopt rules:

  practices for certain weeds and
  maintenance, as defined, and
• Regulate the burning of diseased crops
Smoke Management

• March 2001 - Title 17 California Code
  of Regulations
• Districts given a mandate to develop
  better tools to manage smoke
• Agricultural burning and Prescribed
  burning
Acreage Allocation

• District determines atmospheric
  holding capacity in local geographic
  areas
• Local meteorological data
• Local air quality data
• Local nuisance potential
How Will It Work?
• Permitting process remains the same –
  same cost
• Daily allocation for each geographic area
  will be established by District
• No more burn or no burn days
• Farmers call to request a burn
  - Accepted
  - Reduced acreage
  - Allocation full
Waiting List
• Priority over new requests
• You will receive an automated
  message the afternoon before you can
  burn
• Choose to burn next day or delay up to
  5 times
• Call back to confirm that you will burn
Ways to request a burn

• Talk to an operator in person

• Use an automated phone system

• Use the Internet
