APHIS SUMMARY: We are amending the regulations governing the possession, use, and transfer of listed biological agents and toxins in order to allow for the issuance of provisional registration certificates for individuals and entities and provisional grants of access to listed biological agents and toxins for individuals. These provisional measures are designed to provide additional time for the Attorney General to complete security risk assessments for those individuals and entities for which the Attorney General has received, by November 12, 2003, all of the information required to conduct a security risk assessment. This action is necessary to ensure that research and educational programs are not disrupted.
