# 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 draft IRIS Assessment Plan for naphthalene. 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 each assessment and the type of evidence considered most pertinent to address the scoping needs. EPA is releasing this draft IRIS Assessment Plan for public comment at least 30 days in advance of a public science webinar planned on August 23, 2018.

# DATES:

The 30-day public comment period begins July 5, 2018, and ends August 6, 2018.

# ADDRESSES:

                        The IRIS Assessment Plan for Naphthalene, will be available via the internet on IRIS' website at                         *https://cfpub.epa.gov/​ncea/​iris2/​chemicalLanding.cfm?​substance_​nmbr=​436*                         and in the public docket at                         *http://www.regulations.gov,*                         Docket ID: EPA-HQ-ORD-2014-0527.

# SUPPLEMENTARY INFORMATION:

## I. Background Information on IRIS Assessment Plans

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 scoping and initial problem formulation activities prior to the development of a draft 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, 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 literature                           ( print page 31389)                        search strategies and inclusion/exclusion criteria, particularly with respect to evidence stream (                    *i.e.,*                     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 publicly available.                

## II. Public Webinar

                    In order to allow for public input, EPA is convening a public webinar to discuss the draft IRIS Assessment Plan for naphthalene on August 23, 2018. 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.*
