9 April 2014

The EPA SAB staff office previously announced in the Federal Register (March 25, 2014) an incorrect date for the teleconference of the SAB Chemical Assessment Advisory Committee Augmented for the Review of the Draft Ammonia Assessment (CAAC-Ammonia Panel), the correct date is June 2, 2014 from 1 - 5pm. [SAB FR Notice for April 9, 2014]

4 April 2014

A draft agenda is now available for the April IRIS Bimonthly Public Meeting. The meeting will be held on April 23, 2014 (the second day, April 24, is no longer needed).

An updated preliminary Agenda is now available for the Formaldehyde Workshop,
which will be held on April 30 and May 1, 2014, in the Washington D.C. metro area. A final agenda, additional workshop details, and a specific location will be announced in the near future.

26 March 2014

EPA confirmed the dates for the Formaldehyde Workshop to be held April 30 - May 1, 2014. The workshop is part of EPA's efforts in revising its Integrated Risk Information System (IRIS) toxicological assessment of formaldehyde. This assessment addresses both noncancer and cancer human health effects that may result from chronic inhalation exposure to formaldehyde. To facilitate discussion of several scientific issues pertinent to the assessment, EPA will convene a public state-of-the-science workshop and webinar to discuss these issues.

25 March 2014

The EPA SAB staff office announced two meetings of the SAB Chemical Assessment Advisory Committee (CAAC), augmented for the review of the draft IRIS assessment of ammonia; a public teleconference (06/04/2014) and a face-to-face meeting (07/14 through 7/16/2014). Please visit the SAB website for additional information. Any related questions should be directed to the SAB. [SAB FR Notice for Ammonia March 25, 2014]

25 March 2014

The EPA SAB staff office announced two meetings of the SAB Chemical Assessment Advisory Committee (CAAC), augmented for the review of the draft IRIS assessment of trimethylbenzenes; a public teleconference (5/22/2014) and face-to-face meeting (06/17 through 06/19/2014). Please visit the SAB website for additional information. Any related questions should be directed to the SAB. [SAB FR Notice for TMBs March 25, 2014]

13 March 2014

EPA announced the availability of a new general comments docket for the IRIS Program. This docket will be used to accept public comments that have broad applicability to the IRIS Program, which may include comments on general scientific issues that apply to all assessments and/or other non-chemical-specific comments about the IRIS Program. Our intent is to promote transparency and an open dialogue within the IRIS stakeholder community, therefore commenters are asked to please identify themselves and provide contact information with each submission. This docket does not replace the IRIS Hotline, but rather provides another avenue to submit feedback to the IRIS Program.

6 March 2014

EPA announced the availability of preliminary materials (literature search and search strategy, evidence tables, and exposure-response figures) for diethyl phthalate (DEP) and hexabromocyclododecane (HBCD) for public review and comment. This announcement came with a special message from the IRIS Program. These chemicals will be discussed at the IRIS bimonthly public meeting scheduled for April 23-24th in Arlington, Virginia. Registration is open.

26 February 2014

EPA confirmed the dates for the April 2014 IRIS Bimonthly Meeting to be held April 23-24, 2014 in Arlington, VA. At this upcoming meeting, the IRIS Program will explore a new format intended to promote public discussion of key issues for several assessments under development. The new format is responsive to public comments heard at the December 2013 bimonthly public meeting and reflects the Program’s continuing evolution in response to public comments and peer review advice.

20 February 2014

EPA announced that they will host a workshop to discuss several scientific issues related to its draft Integrated Risk Information System assessment of formaldehyde (inhalation exposure). The workshop will focus on three areas: (1) Epidemiological research examining the potential association between formaldehyde exposure and lymphohematopoietic cancers (leukemia and lymphomas); (2) Mechanistic evidence relevant to formaldehyde inhalation exposure and these types of cancers; and (3) Evidence pertaining to the influence of formaldehyde that is produced endogenously (by the body during normal biological processes) on the toxicity of inhaled formaldehyde, and implications for the health assessment. We will confirm the workshop dates in the very near future. Additionally, we anticipate posting a draft agenda in early March and a final agenda by late March.

12 February 2014

EPA rescheduled the February 18-20, 2014 Science Advisory Board (SAB) Chemical Assessment Advisory Committee (CAAC) Review Meeting to provide the public with additional time to prepare. The purpose of this public meeting is for the SAB CAAC to peer review the draft IRIS assessments of ammonia and trimethylbenzenes (1,2,3-, 1,2,4- and 1,3,5-trimethylbenzene) to provide advice to the Agency through the chartered SAB. Rescheduling the meeting is responsive to stakeholder requests, will provide the public with additional time to prepare for the meeting, and is consistent with the IRIS Program’s practice of providing approximately two months advance notice of its public meetings and the SAB’s commitment to provide at least 45 days advanced notice of meetings. The EPA SAB staff office will reschedule the peer reviews of these draft assessments. Additional information will be provided in the near future.

30 January 2014

EPA's Science Advisory Board (SAB) Staff Office announced three public meetings. The SAB Chemical Assessment Advisory Committee (CAAC) and additional experts will meet in a plenary session to learn about new enhancements to the EPA's process for IRIS health assessments for chemicals. Additional announcements will be posted in the Federal Register. [Federal Register Notice: Jan 30, 2013]

29 January 2014

EPA's Science Advisory Board (SAB) requested nominations for experts to augment the SAB Chemical Assessment Advisory Committee (CAAC) for the review of the EPA's Draft IRIS Assessment for benzo[a]pyrene (BaP). [Federal Register Notice Jan 28, 2014]

16 January 2014

EPA cancelled the February 26-27, 2014, IRIS bimonthly public meeting to allow time to prepare additional materials that will promote more robust discussions at future public meetings based on public comments heard at the December bimonthly public meeting.  The next meeting will be held in April 2014.

7 January 2014

EPA posted the presentations from the IRIS December Bimonthly Meeting.
