List of Regulated Substances under the Risk Management Plan (RMP) Program
The Risk Management Plan (RMP) rule provides a List of Regulated Substances under section 112(r) of the Clean Air Act. This includes their synonyms and threshold quantities (in pounds) to help assess if a process is subject to the RMP rule. Where the Clean Air Act Section 112(r) program has been delegated to a state, that state may have additional requirements for the federally listed chemicals, and/or additional listed chemicals.
