Availability of the IRIS Assessment Plan for Inorganic Mercury 
Salts

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of public comment period.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) is announcing a 30-
day public comment period associated with release of the IRIS 
Assessment Plan for Inorganic Mercury Salts. 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. EPA is releasing this IRIS Assessment Plan 
for a 30-day public comment period in advance of a public science 
webinar planned for December 5, 2019. The Agency encourages the public 
to comment on all aspects of the assessment plan, including key science 
issues.

DATES: The 30-day public comment period begins October 8, 2019 and ends 
November 7, 2019. Comments must be received on or before November 7, 
2019.

ADDRESSES: The IRIS Assessment Plan for Inorganic Mercury Salts will be 
available via the internet on the IRIS website at https://www.epa.gov/iris/iris-recent-additions and in the public docket at https://www.regulations.gov, Docket ID No. EPA-HQ-ORD-2019-0504.

FOR FURTHER INFORMATION CONTACT: For information on the public comment 
period, contact the ORD Docket at the EPA Headquarters Docket Center; 
phone: 202-566-1752; fax: 202-566-9744; or email: Docket_ORD@epa.gov.
    For technical information on the IRIS Assessment Plan for Inorganic 
Mercury Salts, contact Dr. James Avery, NCEA; phone: 202-564-1494; or 
email: avery.james@epa.gov.

SUPPLEMENTARY INFORMATION: 

I. Information About IRIS Assessment Plans

    EPA's IRIS Program is a human health assessment program that 
evaluates quantitative and qualitative information on the health 
effects that may result from exposure to chemicals found in the 
environment. Through the IRIS Program, EPA provides high quality 
science-based human health assessments to support the Agency's 
regulatory activities and decisions to protect public health. As part 
of scoping and initial problem formulation activities prior to the 
development of an assessment, the IRIS Program carries out a broad, 
preliminary literature survey to assist in identifying health effects 
that have been studied in relation to the chemical or substance of 
interest, as well as science issues that may need to be considered when 
evaluating toxicity. This information, in conjunction with scoping 
needs identified by EPA program and regional offices, is used to inform 
the development of an IRIS Assessment Plan (IAP).
    The IAP communicates the plan for developing each individual 
chemical assessment to the public and includes summary information on 
the IRIS Program's scoping and initial problem formulation activities, 
objectives and specific aims for the assessment, and a PECO 
(Populations, Exposures, Comparators, and Outcomes) for the systematic 
review. The PECO provides the framework for developing detailed 
literature search strategies and inclusion/exclusion criteria, 
particularly with respect to evidence stream (e.g., human, animal, 
mechanistic), exposure measures, and outcome measures. The IAP serves 
to inform the subsequent development of chemical-specific systematic 
review protocols, which will be made available for public review.

II. Public Webinar Information

    To allow for public input, EPA is convening a public webinar to 
discuss the IRIS Assessment Plan for Inorganic Mercury Salts on 
December 5, 2019. Specific teleconference and webinar information 
regarding this public meeting will be provided through the IRIS website 
(https://www.epa.gov/iris) and via EPA's Human Health Risk Assessment 
(HHRA) and IRIS listservs. To register for the HHRA or IRIS listserv, 
visit the IRIS website (https://www.epa.gov/iris) or visit https://www.epa.gov/iris/forms/staying-connected-integrated-risk-information-system#connect.

number for the Public Reading Room is 202-566-1744. Deliveries are only 
accepted during the docket's normal hours of operation, and special 
arrangements should be made for deliveries of boxed information. If you 
provide comments by mail or hand delivery, please submit three copies
