EPA’s final evaluation of the solvent n-methylpyrrolidone (NMP) greatly expands the list of industrial uses that pose unreasonable risks compared to the draft version, though the final analysis also narrows the consumer uses that pose such risks and maintains the Trump-era policy of not considering risks that could be addressed under other laws.

President Joe Biden’s recent climate executive order (EO) might signal EPA will pursue a two-track plan for regulating vehicle greenhouse gases, with one track a swift reversal of the Trump administration’s rollback of GHG rules through model year (MY) 2026 but a longer track pursuing stricter GHG rules for later years, sources say.

A coalition of local citizen and environmental groups is urging the Biden administration to embrace aggressive measures to address per- and polyfluoroalkyl substances (PFAS), stressing the need for a White House PFAS “czar” to oversee policy and ensure accountability from the Defense Department (DOD) in addressing the chemicals.

DuPont and its spinoff company The Chemours Company have reached a $4 billion settlement that will pay for potential legacy liabilities for the cleanup of per- and polyfluoroalkyl substances (PFAS), resolving Chemours’ claim that DuPont fraudulently spun off the company and saddled it with excess liability for any contamination.

EPA Acting General Counsel Melissa Hoffer is officially asking the Justice Department (DOJ) to seek judicial pauses in pending litigation challenging agency rules or seeking to establish a deadline for EPA regulation, in order to provide the Biden administration time to review a slew of lawsuits before deciding how to proceed.

The Biden EPA has withdrawn from White House pre-publication review a long-pending Trump administration proposal to exempt some biogenic greenhouse gas emissions from Clean Air Act permitting mandates, and it has also pulled a separate proposed guidance on modeling ozone and fine particulate matter (PM2.5) emissions.

The Biden administration is reviewing and might reverse the Trump EPA’s approvals of Dallas- and Houston-area air quality plans that drop protections against increases in air pollution known as “backsliding,” while Texas and its industry supporters fight the agency to keep litigation over the approvals in a regional federal appeals court.
