EPA has announced that the Second External Review Draft of the Integrated Science Assessment (ISA) for Sulfur Oxides – Health Criteria has been made available for independent peer review and public review. This draft ISA document represents a concise synthesis and evaluation of the most policy-relevant science and will ultimately provide the scientific bases for EPA’s decision regarding whether the current standard for SO2 sufficiently protects public health.
