68 6.1 Introduction to the MAPA Screening Tool 6.1.1 Overview The Managing AFFF and PFASs at Airports (MAPA) Screening Tool has been designed to assist airport managers with the identification of APECs on or near their airport.

Screening tool Guidance 69 AFFF and/or PFASs may exist among different departments at an airport, collaboration among the members of different functional departments is beneficial for working with the MAPA Screening Tool to gain a holistic understanding of an airport's level of potential risk. For example, AFFF management through the life cycle stages (i.e., procurement, storage, use, testing, maintenance, and disposal)

76 Use and potential Impacts of aFFF Containing pFaSs at airports For activities on the drop-down list for the AFFF life cycle stage labeled "Use," the options of "incident response" and "accidental release" are available under the "Historical Operations" section only. This is because these are events that have already happened and are not considered to be current.

82 Use and potential Impacts of aFFF Containing pFaSs at airports The questions posed on the Operational APECs worksheets are mostly related to best management practices: • Storage. Questions posed are focused on how AFFF is being stored at the airport and whether there are any inherent risks with the storage methods in place.

Module 2 Legacy APECs Worksheet Within Module 2, there is a worksheet for APECs identified as legacy, i.e., historical activities that resulted in a release to the environment.

Screening tool Guidance 85 firefighting activities; therefore, this question includes the mass of AFFF released in the assessment of risk. Timing of the release is important for the migration of AFFF in the environment and the type of PFASs contained in the AFFF, as different compositions were used prior to and after 2010.

The results that can be produced by use of the MAPA Screening Tool are the following: • Identification of APECs on and adjacent to airport property.
