A substance is subject to the requirements of this subchapter if the substance is on the list published under paragraph (2).
The Administrator may revise the list and thresholds under paragraphs (2) and (3) from time to time. Any revisions to the list shall take into account the toxicity, reactivity, volatility, dispersability, combustability, or flammability of a substance.
