On September 22, 2006, the draft Evaluation of the Carinogenicity of Ethylene Oxide (EPA/635/R-06/003) and the draft charge to external peer reviewers were released for external peer review and public comment. This draft was reviewed by EPA’s Science Advisory Board (SAB) and the expert panel’s final report was made available December 21, 2007. Since that time the Agency implemented the May 2009 IRIS assessment development process in which other federal agencies and the Executive Offices of the President are provided two opportunities to comment on IRIS human health assessments; Interagency Science Consultation (Step 3) prior to public comment/peer review and Interagency Science Discussion (Step 6b) following peer review. In July, 2011, the draft assessment incorporating the SAB recommendations (December 2007) was sent to other federal agencies and Executive Offices of the President as part of Step 6 of the IRIS process. Following the May 2009 process, all written comments submitted by other agencies will be made publicly available. Accordingly, the interagency comments for ethylene oxide and the interagency science discussion materials provided to the other agencies are posted on this site.
Note: After further consideration EPA has decided to undertake an additional peer review of the revised draft assessment on how the Agency responded to the SAB panel recommendations (December 2007), the exposure-response modeling of epidemiologic data, including new analyses since the 2007 external peer review, and on the adequacy, transparency, and clarity of the revised draft assessment.
