Chemical Assessments: Challenges Remain with EPA’s Integrated Risk Information System Program. GAO-12-42, December 9.

Why GAO Did This Study
The Environmental Protection Agency’s (EPA) Integrated Risk Information System (IRIS) Program supports EPA’s mission to protect human health and the environment by providing the agency’s scientific position on the potential human health effects from exposure to various chemicals in the environment. The IRIS database contains quantitative toxicity assessments of more than 550 chemicals and provides fundamental scientific components of human health risk assessments. In response to a March 2008 GAO report on the IRIS program, EPA revised its IRIS assessment process in May 2009. GAO was asked to evaluate (1) EPA’s progress in completing IRIS assessments under the May 2009 process and (2) the challenges, if any, that EPA faces in implementing the IRIS program. To do this work, GAO reviewed and analyzed EPA productivity data, among other things, and interviewed EPA officials.
What GAO Recommends
GAO recommends, among other things, that EPA assess the feasibility of the established time frames for each step in the IRIS assessment process and make changes if necessary, submit for independent review to an entity with scientific and technical credibility a plan for how EPA will implement the National Academies’ suggestions, and ensure that current and accurate information on chemicals that EPA plans to assess through IRIS is available to IRIS users. EPA agreed with GAO’s recommendations and noted specific actions it will take to implement them.
