Authority to spend $250k

Superfund Division

Resources

  • 22 On-Scene Coordinators

  • 24-Hour Spill Line (913.281.0991)

  • Cache of equipment

  • Reachback capability to other 9 regions and national assests

National issues l.jpg
National Issues

Columbia Shuttle Recovery

Hurricanes Katrina and Rita

Capitol Hill

Anthrax


Background l.jpg
Background

  • Capitol Hill Anthrax response was unique in terms of size, complexity, and nature of contamination

  • Marked the first large scale bioterrorism incident in the Nation

  • First time EPA faced biological weapon contamination

  • Experience and available assessment and decontamination technologies were seriously limited


Challenge l.jpg
Challenge

  • Sampling

    • Sampling efficiency

    • Detection limits

  • Unlike extensive EPA chemical sampling and analysis experience

    • Little was known about the efficiency of media collection for bacillus anthracis(Ba)spores

    • Personnel accustomed to detection limits: not directly translatable to biological assessment

  • Outcome:

    • Sampled virtually every horizontal surface in every room

    • Affected clean-up levels

Gel Set-up

Dry Filter Unit Set-up

Wipe Sampling


Slide14 l.jpg

Swab Sampling

HEPA Sampling


Challenge15 l.jpg
Challenge

  • Decontamination:Personnel Decon

  • No recognized/registered decon-agent and procedure available decon

    • lack of knowledge forced probable excessive PPE SOP

    • developed, w/close FIFRA cooperation effective agent and procedure for decon lines

  • Outcome:decon-agent serviceable:

    however, decon-agent and procedure

    problematic to implement


Challenge17 l.jpg
Challenge

  • Decontamination: Facility Decon

    • Surface Application, for secondary and lower depositional areas

  • Decon agent and SOP for decon of an operational civilian structure non-existent

  • Developed, w/close FIFRA cooperation, effective agent and application procedure for surface application

  • Evaluated several different agents

    • Liquid ClO2 –“Envirofoam” –Bleach mixture

  • Outcome: Success.Application simple on hard surfaces, but requires disposal of “fuzzy” surface items.

    • Some decon-agents problematic

    • Some lower depositional areas so lightly contaminated the act of sampling decontaminates

Fumigation Process

Sabre Tech Services


Challenge24 l.jpg
Challenge

  • Clearance: How Clean is Safe?

    • No safe level of Bacillus anthracis certain

    • Uncertain level of confidence regarding assessment techniques

      • collection efficiency

      • detection levels

      • analytical uncertainties

    • Clean-Up level set at “zero detectable, viable Ba spores”

National decontamination team summary l.jpg
National Decontamination Team Summary

  • Team of 19 full-time employees

  • Established two years ago

  • Attempting to bridge gap between research and end users

  • Ensuring decon technologies can be implemented and able to achieve

    desired clean up goals

  • Actively involved in Interagency coordination on decon issues

  • Providing training and exercises on

    decon technologies and methods
