1 Local Emergency Planning Committee Guideook: Understanding the EPA Risk Management Program Rule y R. J. Walter Copyright 1998 American Institute of Chemical Engineers Appendix B RMP List of Regulated Sustances Introduction The RMP rule includes a list of toxic sustances and a list of flammale sustances regulated y the rule. This section provides this list and descries the procedures for petitioning the EPA to revise the list List of Sustances Regulatory Text (a) Regulated toxic and flammale sustances under section 112(r) of the Clean Air Act are the sustances listed in Tales 1, 2, 3, and 4 [of fj Threshold quantities for listed toxic and flammale sustance are specified in the tales. () The asis for placing toxic and flammale sustances on the list of regulated sustances are explained in the notes to the list. Ally1 alcohol [2-Propen-l-ol] Allylamine [2-Propen-l-aminel

The criteria for acceptance of a proposed change are descried elow: No sustance with a natinal primary amient air quality standard may e added to the list. No sustance regulated under Title VI of the CAA may e added to the list. A sustance may e added to the list if an accidental release of the sustance might reasonaly e expected to cause serious adverse effects to human health or the environment. A sustance may e deleted from the list if it can e shown that an accidental release of the sustance might not reasonaly e expected to cause serious adverse effects to human health or the environment. 115
