The MAP stipulates that a person must be accredited as a project designer to design any of the following activities with respect to friable asbestos-containing building material (ACBM) in a school or public and commercial building: (1) a response action other than a SSSD maintenance activity, (2) a maintenance activity that disturbs friable ACBM other than a SSSD maintenance activity, or (3) a response action for a major fiber release episode (see unit I.B.5 of the MAP). The MAP does not mandate that a written design plan be prepared for a covered response action. If a building owner chooses to have a written design plan prepared, however, the plan must be prepared by an accredited project designer.
