This document communicates the rationale for conducting the assessment of Cr(VI), describes screening criteria to identify relevant literature, outlines the approach for evaluating study quality, and describes the process of evidence synthesis/integration and dose-response methods. The protocol includes the list of studies currently considered in the assessment. EPA is releasing this protocol for public comment at least 30 days in advance of a public science webinar planned on April 24, 2019.

DATES:

The 45-day public comment period begins March 15, 2019 and ends April 29, 2019. Comments must be received on or before April 29, 2019.

ADDRESSES:

The Systematic Review Protocol for Cr(VI) will be available via the internet on the IRIS website at https://cfpub.epa.gov/​ncea/​iris2/​chemicalLanding.cfm?​substance_​nmbr=​144 and in the public docket at https://www.regulations.gov, Docket ID: EPA-HQ-ORD-2014-0313.

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 provides the highest quality science-based human health assessments to support the Agency's regulatory activities and decisions to protect public health.

As part of developing a draft IRIS assessment, EPA presents a methods document, referred to as the protocol, for conducting a chemical-specific systematic review of the available scientific literature. Protocols include strategies for literature searches, criteria for study inclusion or exclusion, considerations for evaluating study methods, information management for extracting data, approaches for synthesis within and across lines of evidence, and methods for derivation of toxicity values. The protocol serves to inform the subsequent development of the draft assessment and is made available to the public. EPA may update the protocol based on the evaluation of the literature and any updates will be posted to the docket and on the IRIS website. In accordance with the most current systematic review practices of the IRIS Program, EPA is releasing the Cr(VI) protocol to provide similar public engagement steps as other IRIS assessments that have started more recently.Start Printed Page 9517
