The Environmental Protection Agency (EPA) is announcing a 30- day public comment period associated with release of the Integrated Risk Information System (IRIS) Assessment Plan and Systematic Review Protocol for Inhalation Exposure to Cobalt and Compounds (Cancer). This document communicates information on the scoping needs identified by EPA program and regional offices and the IRIS Program's initial problem formulation activities. Specifically, the assessment plan outlines the objectives for the IRIS assessment and the type of evidence considered most pertinent to address the scoping needs. The systematic review protocol describes the methodology of how the assessment will be conducted, including dose-response considerations. EPA is releasing this IRIS assessment plan and systematic review protocol for a 30-day public comment period in advance of a public science webinar planned for November 30, 2022. The Agency encourages the public to comment on all aspects of the assessment plan and the systematic review protocol, including key science issues and identification of any new or missing studies.
