Eunice, LA. (Reuters) - Hazardous-chemical
specialists plan to put out fires still burning
in two tank cars of plastics Tuesday and then
begin moving some of 30 freight cars that
derailed Saturday in southwest Louisiana, forcing
2,500 people from their homes.
Residents were ordered to flee from a 2-1/2-mile
radius around the site within minutes....
Dense smoke poured from the scene for almost 24
hours, police said.
... dichloropropane, acrylic acid, methyl
chloride, toluene, diisocyanate, sodium
hydroxide, hexane, and phenol.

Summary

• Potential for ATD modeling to touch every aspect
  of our lives - effects demonstrated daily
• Growing concerns over chemical and biological
  terrorism demand attention
• This workshop will let us assess where we are and
  set a direction for the future

Workshop Goal
Improve agency coordination in the development
and operational use of dispersion models.
14
Workshop Objectives

• State current modeling requirements and
  capabilities
• Specify new requirements/unmet needs
• Describe existing methods for validation,
  verification, and approval of current models and
  future needs
• Describe a process for establishing model subsets
  for specific applications
• Find solutions to agency-identified technical
  barriers
• Identify opportunities for leveraging model
  development and model validation, verification,
  and approval

15
Session 1
Tuesday morning

• User Requirements for Dispersion Modeling
• Agencies current requirements
• How current requirements are being met
• New/unmet requirements

16
Session 2
Tuesday afternoon

• Agency Dispersion Modeling Capabilities
• What models are currently used for operations?
• How does modeling capability meet agency
  requirements?
• How are models evaluated?
• Who are the users what products are distributed
  what are training requirements?
• Research/development for unmet user needs

17
Session 3
Wednesday morning

• Technical Barriers to Dispersion Modeling
• Turbulence and the stable boundary layer
• Air-surface exchange
• Probabilistic modeling
• Mesoscale and surface layer transport
• Neighborhood-scale processes

18
Session 4
Wednesday afternoon

• Model Validation, Verification, and Approval
  Model Subsets
• Develop a framework for the validation,
  verification, and approval of dispersion models
• Identify subsets of scientifically and
  technically sound models suitable for different
  operational scenarios

19
Session 5
Thursday morning

• Summary and Wrap-Up
• Panel and breakout chairs report results and
  recommendations
• Next steps/follow-on actions
• Closing remarks
