The Port will retain a copy of the attestation form. That form will not have names on it. The Port will retain a list of who enters Port offices via a sign-in sheet or similar app being developed for contractors (to eliminate paper sign-in sheets). The sign-in sheet or app information is only used for purposes of contact tracing to help alert individuals who had been in an office at the same time with a person who had reported sickness or a positive case of COVID-19. Contact tracing benefits all parties to avoid greater spread. The sign-in sheet names will not be kept permanently.
