EPA issues final rule regulating “forever chemicals”
The Environmental Protection Agency announced that it will issue a rule aimed at limiting public exposure to per- and polyfluoroalkyl substances (PFAS). The final rule will designate two widely used PFAS chemicals, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as Superfund.
According to the EPA, both PFOA and PFOS meet the statutory criteria for designation as hazardous substances.

A toroidal equilibrium of a poloidal divertor RFP is analyzed as a free boundary problem including an external coil current of a vertical field and a poloidal divertor. Effects of poloidal divertor upon equilibrium parameter of RFP and the proximity of plasma to the conducting shell are investigated and the poloidal divertor configuration is shown to decrease the proximity of plasma to the shell to the value, <rp/aw>≤ 0.75, and be high Θ RFP without additional plasma surface controls.
