2020-16047. Availability of the IRIS Assessment Plan for Oral Exposure to Vanadium and Compounds

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 Oral Exposure to Vanadium and Compounds. 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 August 19, 2020. The Agency encourages the public to comment on all aspects of the assessment plan, including key science issues and identification of any new or missing studies.

DATES:

The 30-day public comment period begins July 24, 2020 and ends August 24, 2020. Comments must be received on or before August 24, 2020.

ADDRESSES:

The IRIS Assessment Plan for Oral Exposure to Vanadium and Compounds 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 http://www.regulations.gov,, Docket ID No. EPA-HQ-ORD-2020-0182.

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 Oral Exposure to Vanadium and Compounds on August 19, 2020. 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 IRIS listserv. To register for the 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.

No hand deliveries are currently being accepted.

Instructions: Direct your comments to Docket ID No. EPA-HQ-ORD-2020-0183. Please ensure that your comments are submitted within the specified comment period. Comments received after the closing date will be marked “late,” and may only be considered if time permits. It is EPA's policy to include all comments it receives in the public docket without change and to make the comments available online at www.regulations.gov,, including any personal information provided, unless a comment includes information claimed to be Confidential Business Information (CBI) or other information for which disclosure is restricted by statute. Do not submit information through www.regulations.gov or email that you consider to be CBI or otherwise protected. The www.regulations.gov website is an “anonymous access” system, which means EPA will not know your identity or contact information unless you provide it in the body of your comment. If you send an email comment directly to EPA without going through www.regulations.gov,, your email address will be automatically captured and included as part of the comment that is placed in the public docket and made available on the internet. If you submit an electronic comment, EPA recommends that you include your name and other contact information in the body of your comment and with any disk or CD-ROM you submit.
