      "summary": "This report compiles the provisions in federal environmental statutes that explicitly state whether\nCongress intended to preempt state law. The provisions are arranged in four categories, from least\npreemption to greatest: (1) rights/jurisdiction of state generally unaffected; (2) if a federal standard\nexists, the state standard must be the same or more stringent; (3) state regulation different from the\nfederal scheme is preempted, but a waiver may be available; and (4) state regulation different from\nthe federal scheme is preempted, and no waiver is available.",
