SUPPLEMENTARY INFORMATION:

I. Information on the IRIS Program and Systematic Review Protocols

    EPA's IRIS Program is a human health assessment program that 
evaluates quantitative and qualitative risk information on effects that 
may result from exposure to chemicals found in the environment. Through 
the IRIS Program, EPA strives to provide high quality science-based 
human health assessments to support the Agency's regulatory activities 
and decisions to protect public health.
    The IRIS Program is developing an updated Toxicological Review of 
Inorganic Arsenic. Given the size and complexity of the evidence base 
for this chemical, input on the scope of this assessment has been 
sought from the National Academy of Sciences, Engineering, and Medicine 
(NAS), EPA Program and Regional Offices, other federal agencies, and 
public stakeholders to help focus the objectives of the assessment and 
ensure it is transparently conducted. The Updated Problem Formulation 
and Protocol summarizes the Agency's need for the assessment and 
presents the refined focus based on problem formulation activities 
conducted since the last assessment plan released to the NAS in 2015. 
In July 2019, an NAS ad hoc committee will conduct a peer review of the 
revised scope of the assessment and determine whether the proposed 
methods are appropriate to synthesize the scientific evidence and 
develop conclusions. The peer review charge questions will be available 
in the docket prior to the NAS meeting.
