Integrated Science Assessment (ISA) for Sulfur Oxides – Health Criteria (Second External Review Draft, Dec 2016)

Notice:

[UPDATE] EPA announced the public teleconference will be held on June 20, 2017 in a May 23, Federal Register Notice. In Dec 2016, EPA announced the availability of the Second External Review Draft of the Integrated Science Assessment for Sulfur Oxides– Health Criteria for public comment and independent peer review in a December 9, 2016 Federal Register Notice. The deadline for comments was March 20, 2017.

U.S. EPA. Integrated Science Assessment (ISA) for Sulfur Oxides – Health Criteria (Second External Review Draft, Dec 2016). U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-16/351, 2016.

Impact/Purpose:

The intent of the ISA, according to the CAA, is to “accurately reflect the latest scientific knowledge expected from the presence of [a] pollutant in ambient air” (U.S. Code, 1970a, 1970b). It includes an assessment of scientific research from atmospheric sciences, exposure sciences, dosimetry, mode of action, animal and human toxicology, and epidemiology. Key information and judgments formerly found in the Air Quality Criteria Documents (AQCDs) for sulfur oxides (SOx) are included; Annexes provide additional details supporting the ISA. Together, the ISA and Annexes serve to update and revise the last SOx ISA which was published in 2008.

Description:

This draft document provides EPA’s evaluation and synthesis of the most policy-relevant science related to the health effects of sulfur oxides. When final, it will provide a critical part of the scientific foundation for EPA’s decision regarding the adequacy of the current primary (health-based) National Ambient Air Quality Standard (NAAQS) for sulfur dioxide.
