Title 42 › CHAPTER 103 — COMPREHENSIVE ENVIRONMENTAL RESPONSE, COMPENSATION, AND LIABILITY › SUBCHAPTER III — MISCELLANEOUS PROVISIONS › § 9658
If a state says the clock for suing over injury or property harm from a hazardous substance starts earlier than federal rules allow, the federal start date must be used instead. If the state start date is not earlier, the state's time limits apply. These rules do not apply to claims brought under section 9607. Words used here mean the same as in subchapter I. "Applicable limitations period" is the time you have to bring the lawsuit. "Commencement date" is the day that time starts. "Federally required commencement date" is the day the person knew or should have known the harm was caused by the hazardous substance. For a minor or someone not competent, that federal start date is the later of the discovery date or the date they reach majority, become competent, or get a legal representative.
