430 ILCS 45/2

(a) The General Assembly finds: (1) that the presence of chemical substances at facilities may pose potentially acute threats to human health and the environment if such substances are released into the environment; (2) that a large number and amount of these chemical substances are currently stored and used at facilities around the State; and (3) that current laws and regulations are not adequate to protect the public from sudden releases of chemical substances. (b) It is the purpose of this Act to establish an orderly system to assure that responsible parties are adequately prepared to respond to the release of chemical substances into the environment and to improve the ability of State and local authorities to respond to such releases.
