Lynn L. Bergeson, “EPA Updates IRIS Process, Again,” ABA Pesticides, Chemical Regulation, and Right-to-Know Committee Newsletter, Vol. 10, No. 4, June 2009.

The U.S. Environmental Protection Agency (EPA) announced on May 21, 2009, that it has reformed the Integrated Risk Information System (IRIS), again. According to EPA, the revisions are intended to “revitalize the program and ensure its scientific quality, integrity, transparency and timeliness.” In a May 21, 2009, memorandum, Administrator Jackson states that recent changes, including procedures formalized in an April 21, 2008, memorandum, “have reduced the transparency, timeliness, and scientific integrity of the IRIS process.”
