IRIS Plagued by Lack of Transparency, Delay, Congressmen Say

Rep. Brad Miller (D-NC) wrote to the White House June 11 asking about the Office of Management and Budget's role in EPA's revised process for assessing the health effects of industrial chemicals. EPA announced changes to the process, known as the Integrated Risk Information System (IRIS), in April.

One of the major problems with the revised process is the lack of transparency. OMB and other federal agencies will be able to have input into a chemical assessment without ever disclosing their views — scientific or political — to the public. Miller wrote to Susan Dudley, the head of OMB's Office of Information and Regulatory Affairs (OIRA), which will coordinate the OMB/interagency review of IRIS assessments, expressing his concern:

[T]he interagency process OIRA manages is secret. The public has no insight into who is being invited to discuss what, when. The public has no way of getting at materials associated with those discussions because the pre-decisional exemption of the Freedom of Information Act (FOIA) applies to all of those materials.

The bottom line is that if the interagency discussion taking place is solely about science, there is no reason why that discussion and all communications surrounding it, cannot survive the light of exposure to the public. The only reason to hide a discussion about science is if the discussion is actually not about science, but about other things that are being used to trump the science.

Miller is the chair of the House Science Committee subcommittee on Investigation and Oversight. Yesterday, the subcommittee held its second hearing on the changes to the IRIS process.

During the hearing, ranking member James Sensenbrenner (R-WI) discussed another problem with the revised process: the delayed completion of IRIS assessments and subsequent backlog of chemicals needing to be assessed. Sensenbrenner pointed out that EPA has completed only two IRIS assessments in each of the last two years, and called the process "broken down."

Sensenbrenner then addressed the OMB/interagency review which will allow other federal agencies, such as the Department of Defense or NASA, to delay the assessment process:

[EPA] argues that it can expedite the IRIS process by involving other agencies earlier in the process. While preventing last minute delays is an important reform, the ability of other agencies to extend the time frame of assessments should be sharply limited. Data gaps in risk assessments will always exist, as better science is always developing. The EPA needs to limit the time frame of assessments to prevent other agencies from indefinitely delaying the process.
