Amends the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) to preempt a state statute of repose for actions brought under state law for personal injury or property damages caused from or contributed to by exposure to any hazardous substance, pollutant, or contaminant, if the state statute provides a commencement date that is earlier than the federally required commencement date. (Currently, CERCLA preempts state statutes of limitations, which limit the amount of time a lawsuit can commence from the time the contamination is discovered. The Supreme Court ruled in CTS Corp. v. Waldburger that North Carolina's statute of repose was not preempted by CERCLA. That statute of repose limits the amount of time a lawsuit can commence to 10 years from the defendant's last action, regardless of when the contamination is discovered.)
