Reassessment (HSNO)
Reassessment (HSNO) : A re-evaluation available only for a substance that has previously been approved or a new organism in containment. A reassessment can only occur when some combination of significant new information has become available about effects, or (in the case of hazardous substances) a better substance has become available or there have been significant changes in the way it is being used or the quantity used. The re-evaluation proceeds in the same way as for an original application for approval. See also Assessment
