On November 13, 2012, EPA held a meeting in Arlington Virginia to hear the views of the Integrated Risk Information System (IRIS) Program from the public and interested stakeholders about changes that are underway to improve the IRIS Program.
Committed to proactively engaging stakeholders, EPA is increasing transparency, and using the best available science to develop these assessments. This public meeting was the beginning of an ongoing dialogue about IRIS with open public participation. Environmental protection decisions, based in part on EPA's IRIS assessments, can have potentially large impacts on the environment, human health and the economy. Because of this, it is important that EPA benefit from stakeholder and scientific engagement to support the best decisions possible.
