The Environmental Protection Agency (EPA) is improving its scientific integrity, according to a government auditor who testified before the Senate Environment and Public Works Committee on 9 June 2009. Specifically, the Integrated Risk Information System (IRIS), which establishes safe exposure levels for over 540 chemicals, will now be regulated directly by the EPA. During the Bush administration, interagency consultations on risk were coordinated by the White House Office of Management and Budget. This process led to accusations by various stakeholder groups that Bush administration officials were interfering with the use of science in the regulatory process. Under the new process, EPA will be able to independently gather input from other agencies as long as it is from scientists focusing on technical matters, and all written comments on IRIS are made public.
