Identifying Experts in Support of EPA's IRIS Public Science Meetings

Background

The Integrated Risk Information System (IRIS) program is used by the US Environmental Protection Agency (EPA) to evaluate scientific information on toxicologic effects that may result from exposure to chemical substances in the environment. The IRIS database contains toxicologic information on chemical substances that can be combined with other considerations to make risk management decisions, including regulations. Additional information on the IRIS program is available here.

 

A 2014 National Research Council (NRC) report, Review of EPA’s Integrated Risk Information System (IRIS) Processapplauded EPA initiatives to involve stakeholders to a greater extent in the IRIS process.  The report indicated that early and continuing stakeholder involvement will help EPA address the concerns of diverse stakeholders and should strengthen the quality of IRIS assessments.

 


Supplementing the IRIS Process for Obtaining Public Input

One of the ways that EPA’s IRIS program seeks public input is by holding public meetings to discuss IRIS assessments under development. As indicated by EPA, members of the public are able to discuss key science topics at IRIS public science meetings at their own initiative by indicating their intent to do so during registration for an upcoming meeting here. To supplement the input provided by those individuals, EPA asked the National Academies of Sciences, Engineering, and Medicine to identify subject-matter experts to contribute to the discussions at IRIS public science meetings. The input provided by experts identified by the Academies is intended to ensure that a range of scientific perspectives on key science topics is represented at the meetings. A few weeks prior to an upcoming meeting, EPA will post an agenda on its website, which includes Academies-identified discussants and any other members of the public who registered at their own initiative.

 

 

The Academies' Process for Identifying Expert Participants

After EPA announces the chemicals and key science questions or topics to be discussed at an upcoming public science meeting, Academies staff will solicit suggestions from groups that have an interest in the underlying subject matter, professionals with knowledge and expertise in relevant disciplines, and the general public.

 

The Academies will select a limited number of individuals after considering each candidate’s availability for participation in the public science meeting, relevant expertise and scientific points of view (or bias) concerning the key science questions provided by EPA, and potential conflicts of interest (such as financial interests).

 

The names of the experts who have been selected by the Academies to participate in the IRIS public science meeting and their biosketches will be made available on this website in advance of the meeting.

 

The Academies will reimburse the experts for their travel-related expenses as needed.

 

Upcoming Meeting

On October 26, 2016, EPA will hold an IRIS Bimonthly Public Science Meeting on Ethyl tert-butyl ether (ETBE).

Biosketches of Academies-identified discussants are provided here.
