The Environmental Protection Agency (EPA) has announced changes to its process for evaluating the risks of chemicals to human health. The changes to the Integrated Risk Information System (IRIS) Program aim to improve the scientific foundation of assessments, increase transparency, and increase the program’s efficiency.

At the recommendation of the National Research Council, EPA will now hold a public meeting early in the assessment development process. The agency will also provide more detailed information regarding assessment schedules, stakeholder meetings, and updates on IRIS progress on the program’s website.

Cut-off points for accepting new data and raising scientific issues will be implemented. According to the EPA, the change will enable the agency to conduct more health assessments each year.
