HR 1415 would permanently ban the EPA from using its IRIS chemical health risk database in any regulation, permit, or enforcement action.

40-second read · 4 questions answered below

What does this do?

This bill would permanently stop the EPA from using its Integrated Risk Information System, known as IRIS, in any regulatory or enforcement work. That includes writing new rules, issuing permits, enforcing existing rules, and creating air quality maps and screening tools.

Who does it affect?

This bill directly affects the EPA and its ability to use one of its own scientific databases. It could also affect industries the EPA oversees, as well as communities whose health protections are based on rules that relied on IRIS data.

Why does it matter?

Without access to IRIS, the EPA could not use that database's chemical health risk information to justify or shape its decisions. Regulations and protections that were informed by IRIS data could be harder to maintain or update going forward.
