• Process
• Results
• Benefits

3
PAWSA Background

• Congressional mandate under 1997 DOT
  Appropriations Act
• Identify minimum user requirements in
  consultation w/local maritime industry
• Review Private/Public Partnerships
• Marine Transportation System (MTS)
• In parallel with the recommendations of the
  marine board

4
The National Dialogue Group

• American Association of Port Authorities
• American Pilots Association
• American Waterways Operators
• Council of American Master Mariners
• INTERTANKO
• Passenger Vessel Association
• Natural Resources Defense Council
• U.S. Chamber of Shipping
• U.S. Coast Guard

5
NDG Tasks

• Identify the information needs of the mariner
• Define what a baseline VTS should include
• Develop a process for determining where vessel
  traffic management needs to be improved

6
Three Keys

• Involve Users Stakeholders
• Tailor Specific Actions
• Address Risks

7
PAWSA Development

• Port Risk Model
• Based On NDG Input
• Analytical Hierarchy Process
• Credible / Defensible

8
PAWSA Purpose

• Forum and effective tool for evaluating risk and
  defining solutions for mitigation.
• Determine if VTM improvements are needed through
  open dialogue with port stakeholders
• Provide support for investment decisions
