Many chemicals and hazardous substances are kept in places that can withstand ordinary rain, but not severe storms or floods. If these events occur and the chemicals are released, people and the environment may be endangered. This Article discusses the hazards posed to chemical and waste disposal facilities by extreme weather events that would be worsened as a result of climate change, and how U.S. laws do (or do not) deal with these hazards; and considers how the law would need to change to cope with what would happen to these facilities in a potentially 4°C world. It is adapted from a new book by the Environmental Law Collaborative (Katrina Kuh & Shannon Roesler eds., ELI Press forthcoming 2023).
