Provides for continuous monitoring of all devices and systems, storage facilities, and transfer points in which covered substances are present. Requires owners and operators of facilities subject to such requirements to audit such facilities to determine the locations of such systems, storage facilities, and transfer points. Directs owners and operators to certify compliance to the State and the Administrator. Requires monitoring reports to be filed annually with the State, the Administrator, the State Emergency Response Committee, and the local emergency planning committee.
