AVIATION DIVISION RAMP INSURANCE PROGRAM 
BACKGROUND 
The Port of Seattle Airport Schedule of Rules and Regulations policy establishes insurance requirements for all motor 
vehicles and equipment accessing Air Operations Areas (AOA). The AOA is an area "enclosed by the Airport security fence, 
including ramps, aprons, runways, taxiways, gate positions, airport parking areas, and FAA facilities." 
The Airfield Operations Department oversees the Aviation Ramp Insurance Program to ensure that all vehicles/equipment 
driving onto the Airfield are properly insured. The program is necessary to mitigate the financial loss to the Port in the 
event of an accident. Although the Airfield Operations is primarily responsible for the program, there are other Aviation 
departments from Aviation Security to Aviation Business Development who are indirectly involved in the program. 

STATISTICS HIGHLIGHTS 
For the period January 1, 2015, through July 6, 2015, approximately 297 companies accessed the airfield. These companies 
employ more than 8,000 non-Port employees who use vehicles to access the airfield at various times throughout the year.
See below statistics.

AUDIT OBJECTIVES AND SCOPE 
The purpose of this audit was to determine whether Port management controls are designed and operating effectively to
ensure:

2. Compliance with the Port policy (Sections of 6E. of Seattle-Tacoma International Airport  Schedule of Rules and
Regulations No. 5) and the procedure (Ramp Insurance requirements).

AUDIT RESULT 

Port Management controls are inadequate to mitigate risks related to uninsured vehicles and/or vehicles without proper 
insurance accessing Sea-Tac airfield. Further, Port management does not have a comprehensive and effective process to 
verify insurance compliance for activity on the airfield. 
One Reportable Finding 
1. Port management ramp insurance controls are not adequate to mitigate the risks of uninsured or underinsured vehicles 
accessing the airfield in the following areas: 
Untimely Processing of Submitted Insurance Certificates 
Insufficient Coordination Among Port Departments 
Insufficient Monitoring of Insurance at Each Gate Onto the Airfield

PURCHASING CARD PROGRAM 
BACKGROUND 
The Port of Seattle introduced a new procurement card program and policy (CPO-7) in April 2011. The P-card is a credit 
card-based system used to purchase non-strategic goods and services. The program provides a more efficient process for 
small dollar purchases. It additionally reduces the transaction costs of purchasing routine goods and services. 
The transaction limit on a single P-card purchase is $5,000, with a typical monthly maximum expenditure of $25,000, with a 
few cardholders having higher limits based on business needs. 
As of May 2015, there were some 126 active cards. The total procurement card expenditures for the period January 1, 2014 
through May 31, 2015 were over $12 million.
