BRENTWOOD OVERVIEW

1
Hamilton Township, NJ Processing
Distribution Center Response to
Anthrax April 10, 2003
2
October 18, 2001

• Trenton facility closed
• Actions begun to secure the area and begin
  sanitization of the entire facility
• Engaged experts from various agencies for
  expertise in decontaminating the facility

3
Time

• Unofficial Motto Do it Right, Not Fast
• We are not bound by time constraints
• We will not re-open Trenton until decontamination
  process results proven successful by the experts

4
Challenges

• Anthrax spores aerosolized to maximize damage
• Finer and travel quickly
• 5.8 million cubic feet of space to decontaminate
  in Trenton
• Hart Senate office building only about 100,000
  cubic feet
• Curseen-Morris facility in Washington, DC about
  14.2 million cubic feet

5
Plan Strategy

• Stabilize Area
• Secure Facility
• Remove Contaminated Material
• Sanitize Facility
• Re-Inspect Facility
• Re-Open Once Proven Safe

6
Process

• Clean all surfaces and equipment with approved
  cleaning solution
• Seal all openings in building with thermal foam
• Including all cracks, vents, truck bays and
  skylights
• Adjust and maintain environment at 75 F and 75
  relative humidity for best results
• Use existing HVAC system and delivery system to
  pump in chlorine dioxide gas (ClO2)
• Maintain 750 ppm concentration for 12 hours
• Sample to ensure safety
• Ventilate completely before re-opening

7
Phase I

• Pre-Decontamination
• Seal the facility
• Reach agreements with contractors
• Construct the ClO2 delivery system
• Secure the necessary permits
• Conduct required tests
• Hold community meetings

8
Phase II

• Decontamination
• Maintain appropriate building temperature (75F)
  and humidity (75 relative humidity)
• Deliver the ClO2 gas
• Collect environmental and characterization
  samples
• Ventilate the building

9
Phase III

• Post-Decontamination
• Send samples to labs for testing
• Obtain results
• Breakdown ClO2 delivery system
• Service mail sorting equipment
• Building maintenance and refurbishment

10
Chlorine Dioxide

• ClO2 will be converted to gaseous form once it
  enters the building
• ClO2 is visible yellow/green color you can see
  it and smell it
• ClO2 dissipates quickly in sunlight and open areas

11
Monitoring

• Stationary air monitors will be placed around
  buildings perimeter and inside the facility
• Test strips will be placed throughout the
  building before the decontamination process
  begins
• All environmental samples must return a negative
  before Trenton re-opens for business

12
Process Successful in DC

• Extensive testing of over 5,000 environmental
  samples showed no growth of anthrax
• Refurbishing crews will enter soon to get
  facility ready for re-occupancy this summer
• Trenton community and leadership can rest assured
  theyre benefiting from a process proven
  successful twice already

13
Same Process, Same Team

• The same firms that worked with USPS Engineering
  to successfully decontaminate the Washington
  facility have been contracted to perform the same
  work at the Trenton plant
• Shaw Environmental Infrastructure
• Sabre Technologies
• Ashland Inc.

14
Partnerships

• Environmental, health and safety experts applying
  their knowledge and best practices to this
  unprecedented incident

• US Air Force
• US Army
• AFRRI
• ERT
• Local DOH

• USPS
• EPA
• OSHA
• OSTP
• NIOSH

15
Next Steps in Trenton

• Complex fumigation and delivery systems being
  cleaned and dismantled in Washington
• Project engineers currently evaluating equipment
  needed for Trenton and what will be transported
• Installation of equipment will begin following
  its arrival

16
Next Steps in Trenton

• Decontamination plans have been in development
  for over a year, now facing implementation phase
• No exact start date yet, but expected to fumigate
  by the end of 2003
• USPS will work with federal, state and local
  officials to minimize impact to community and
  surrounding neighborhood
