How long is the SRA valid?
An SRA for individuals that will have access to select agents and toxins is valid for a period not to exceed three years. APHIS or CDC can cancel approval at any time based on new information germane to the SRA. A registered entity can of course deny access to select agents and toxins to an individual at any time the entity determines that the individual no longer has a legitimate need to handle or use such agents and toxins. The RO, ARO, individuals that own or control an entity, and non-exempted entities must obtain SRA approval each time the certificate of registration is renewed. A certificate of registration is valid for a maximum of three years.
