One of the most fundamental tenets of toxicology is that "the dose determines the poison." This simple phrase provides the basis for the belief that all agents—chemicals and physical phenomena that are capable of producing some effect—have the potential to cause toxicity. Whether toxicity actually occurs is principally a matter of dose: the greater the exposure to a given agent, the more pronounced or severe the response of a cell or organism.

Earlier this year in KFC Western, Inc. v. Meghrig, the U.S. Court of Appeals for the Ninth Circuit ruled that private parties may obtain restitution of the costs of cleaning up contaminated property under §7002(a)(1)(B) of the Resource Conservation and Recovery Act (RCRA). The Ninth Circuit's ruling in KFC Western opened the way for private parties to use the RCRA citizen suit provision to recover their costs of investigating, studying, and cleaning up contaminated property from responsible parties.

Offshore areas are under pressure to industrialize for renewable energy. To plan for offshore wind development, Rhode Island engaged in a marine spatial planning process that resulted in the Ocean Special Area Management Plan (O-SAMP), a regulatory invention of the Coastal Zone Management Act.
