Economic theory suggests that pollution tax and cap-and-trade regulations can be functionally equivalent. Environmentalists tend to prefer the firm emissions cap in cap-and-trade programs, while economists and business interests tend to prefer the price certainty of tax programs.

Superfund practitioners are waiting to see whether the U.S. Environmental Protection Agency (EPA) will designate perfluorooctanoic acid and perfluorooctane sulfonate, two chemicals in the per- and polyfluoroalkyl substances (PFAS) group, as CERCLA hazardous substances. Such a designation may lead to selected remedies being modified and further work being required at Superfund sites where remedies were believed to be complete. This Article explores potential future liability by reviewing provisions of the 2021 Remedial Design/Remedial Action (RD/RA) Model Consent Decree.
