Notice Of A Series Of Public Meetings And The Availability Of Preliminary Materials.

Summary

EPA's Integrated Risk Information System (IRIS) Program is committed to proactive stakeholder engagement, increased transparency, and using the best available science in IRIS assessments. In accordance with the recently announced enhancements of the IRIS Program, EPA is announcing a series of public meetings for calendar years 2013 and 2014 to obtain public input at specific stages in the process of developing an IRIS assessment.

EPA is also announcing the availability of preliminary materials for three chemicals, tert-butyl alcohol (tert-butanol), ethyl-tert-butyl ether (ETBE), and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), which will be discussed at the first public meeting scheduled for October 23-24, 2013. The preliminary materials for tert-butanol and ETBE are posted on the IRIS Web site, and the preliminary materials for RDX will be posted approximately 60 days before the meeting. These materials are being released for public viewing and comment prior to the public meeting on October 23-24, 2013, which will provide an opportunity for the IRIS Program to engage in early discussions (before the IRIS assessments have been prepared) with stakeholders and the public on data that may be used to identify health hazards and characterize exposure-response relationships.

SUPPLEMENTARY INFORMATION: Back to Top

I. Information about IRIS Back to Top

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 chemical substances 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. The IRIS database contains information for more than 500 chemical substances that can be used to support the first two steps (hazard identification and dose-response evaluation) of the human health risk assessment process. When supported by available data, IRIS provides health effects information and toxicity values for health effects (including cancer and effects other than cancer). Government and others combine IRIS toxicity values with exposure information to characterize public health risks of chemical substances; this information is then used to support risk management decisions designed to protect public health.

II. IRIS Public Meetings Back to Top

Public meetings will be held approximately every 2 months beginning on October 23-24, 2013. Materials for the public meetings will be posted on the IRIS Web site (http://www.epa.gov/iris/publicmeetings/) well in advance of the meeting (generally 60 days). The meetings will provide an opportunity for the public to provide input on preliminary materials prior to development of the draft assessment and provide input on drafts of assessments and charges to the peer review panels prior to external peer review. The planned meeting dates for calendar years 2013 and 2014 are: October 23-24, 2013; December 12-13, 2013; February 26-27, 2014; April 23-24, 2014; June 25-26, 2014; September 3-4, 2014; October 29-30, 2014; and December 15-16, 2014.

In step 1 of the IRIS process (development of the draft assessment), EPA will release preliminary materials comprised of draft literature search strategies describing the processes for identifying and screening scientific literature and the literature search results, and preliminary evidence tables and preliminary exposure-response arrays summarizing key characteristics and findings from critical studies that EPA proposes to consider in identifying hazards and characterizing exposure-response relationships. EPA will hold a public meeting to discuss these materials. In step 4 of the IRIS process (public review and comment/independent expert peer review), EPA will release the draft assessment and draft peer review charge for public comment and also hold a public meeting to discuss these materials.

The draft literature search strategies, preliminary evidence tables, and preliminary exposure-response arrays are responsive to the National Research Council (NRC) 2011 report Review of the Environmental Protection Agency's Draft IRIS Assessment of Formaldehyde, in which the NRC recommended ways to improve the development of IRIS assessments. The literature search strategies, which describe the processes for identifying scientific literature, screening studies for consideration, and selecting studies to include in evidence tables, are responsive to NRC recommendations regarding systematic review of the scientific literature. The preliminary evidence tables and preliminary exposure-response arrays are responsive to the NRC recommendation for presenting key study data in a standardized manner.

EPA welcomes all comments on the draft literature search strategies, preliminary evidence tables, and preliminary exposure-response arrays, including comments on:

  • The clarity and transparency of the materials;
  • the approach for identifying pertinent literature;
  • the selection of studies for data extraction to preliminary evidence tables and exposure-response arrays;
  • methodological considerations that could affect the interpretation of or confidence in study results; and
  • additional studies published or nearing publication that may provide data for the evaluation of human health hazard or exposure-response relationships.

The IRIS Program believes that public involvement can be most beneficial at the early stages of developing an assessment. Releasing the draft literature search strategy, preliminary evidence tables, and exposure response arrays early will ensure that critical research is not omitted and communicates to the public why critical studies were chosen for further evaluation, helping frame major scientific issues and ultimately leading to more efficient production of assessments. In order to promote such early public involvement and increase transparency, EPA will in many cases be releasing materials that reflect preliminary deliberations that are subject to further evolution as the assessment continues. Consequently, meeting materials provided at the early stage of an assessment, such as preliminary evidence tables, have not been subjected to external peer review, and they do not constitute EPA policy, nor represent any Agency determination. Such materials are being distributed with the sole objective of facilitating a public meeting that is intended to promote the use of the best available science and improve the utility and clarity of IRIS assessments.

III. Meeting Registration and Presentations Back to Top

Registrants will be required to provide their name, title, affiliation, sponsor (if different from affiliation), and contact information. If you intend to request time on the agenda to make a specific presentation, please register no later than 30 days before the meeting to attend in person or via webinar/teleconference. All other participants should register no later than 7 days before the meeting. Participants that want to make a specific presentation should indicate such in their registration and provide the length of time required. In general, presentations should be no more than 30 minutes. Please submit any written materials to the appropriate docket number for the subject chemical, as specified in Section III of this notice, no later than 7 days before the meeting. If there are more requests for presentations than time allows, the time limit for each presentation will be adjusted. During the meeting, remote attendees and individuals attending the meeting in person are welcome to make comments, ask questions, and participate in the dialogue. Details regarding registration procedures (in person, via webinar, or teleconference) will be posted on the IRIS Web site (http://www.epa.gov/iris/publicmeeting/).

IV. Meeting Materials and Public Involvement Back to Top

Materials for the public meetings will be posted well in advance (generally 60 days) of each meeting on the IRIS Web site (http://www.epa.gov/iris/publicmeeting/). A limited number of paper copies will be available from the Information Management Team, NCEA; telephone: 703-347-8561; facsimile: 703-347-8691. If you request a paper copy, please provide your name, mailing address, and the title of the document you are requesting.

V. October 23-24, 2013, Public Meeting on tert-Butanol, ETBE and RDX Back to Top

The October 23-24, 2013 public meeting will be devoted to discussing the preliminary materials for tert-butanol, ETBE, and RDX. The preliminary materials for tert-butanol and ETBE are posted on the IRIS Web site (http://www.epa.gov/iris/publicmeeting/), and the preliminary materials for RDX will be posted approximately 60 days before the meeting on or about August 23, 2013. The tert-butanol materials will be discussed first, followed by ETBE and RDX. EPA may add additional chemicals to the agenda if materials become available in time to allow adequate notice to the public. If additional chemicals are added to the October 23-24, 2013 meeting agenda, they will be posted on the IRIS Web site approximately 60 days before the meeting on or about August 23, 2013. A more detailed agenda for the meeting will be posted on the IRIS Web site shortly after speaker registration closes.

The preliminary evidence tables and preliminary exposure-response arrays should be regarded solely as representing the data on each endpoint that have been identified as a result of the draft literature search strategy. They do not reflect any conclusions about hazard identification or dose-response assessment. After obtaining public input and conducting additional study evaluation and data integration, EPA will revise these materials to support hazard identification and dose-response assessment in the draft Toxicological Reviews for tert-butanol, ETBE, and RDX.

For the October 23-24, 2013 meeting, if you intend to request time on the agenda to make a specific presentation, please register no later than September 23, 2013. All other participants should register no later than October 16, 2013. Please submit any written materials (including scheduled presentation materials) to the appropriate docket number specified in Section III of this notice no later than October 16, 2013. If there are more requests for presentations than time allows, the time limit for each presentation will be adjusted. Details regarding registration procedures (in person, via webinar, or teleconference) will be posted on the IRIS Web site.
