Resolution Urging States to Not Allow the Use of IRIS Assessments to Inform its Rulemakings

NOTE: Prior to task force meetings, ALEC posts these legislative member-submitted draft model policies to our website. The draft model policies are then discussed, debated, and voted on by ALEC task force members. Policies that receive final approval by legislators on the ALEC Board of Directors become official ALEC model policy. Draft model policies that fail to become official ALEC model policy are removed from the website.


This model resolution urges state agencies to rely on the best available and most relevant scientific information as the basis for decision-making and to not permit the use of EPA Integrated Risk Information System (IRIS) assessments as a primary data source for state agency hazard or risk assessments or as the foundation for state air, water, or waste regulatory action.

Resolution Urging States to Not Allow the Use of IRIS Assessments to Inform its Rulemakings

WHEREAS, many state agencies are required to use IRIS assessments, including determinations on key hazards and toxicity values, in regulatory, permitting, enforcement, or clean-up decisions; and

WHEREAS, the policy decision to use IRIS assessments have often been adopted without legislative authorization or an open notice-and-comment rulemaking process; and

WHEREAS, IRIS toxicity values are often set below natural, background levels, monitoring detection limits, or levels of the substance produced by the human body or other natural processes; and

WHEREAS, IRIS process and scientific conclusions have been criticized by federal agencies (including the White House Office of Management and Budget, Department of Defense, and Small Business Administration), the National Research Council, states, and the Government Accountability Office; and

NOW, THEREFORE, LET IT BE RESOLVED that (state legislature) hereby urges the (state regulatory agencies) to not permit the use of IRIS for use as the basis of hazard assessment or risk assessment decisions or as the basis to establish air, water or waste rulemaking.
