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.

California’s toxics department is proposing through its Safer Consumer Products (SCP) green chemistry program to list motor vehicle tires containing the anti-cracking chemical N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) as a “priority product” for future regulation, after finding the substance is killing fish in state waterways.

Environmental groups are urging EPA to swiftly reaffirm its use of a key agency risk assessment for the solvent ethylene oxide (EtO) when it reconsiders a chemical sector air toxics rule, but they are also pressing the agency to formally reconsider a wider range of issues than it so far has granted, which they say will help justify tightening the rule.

Democratic-led states, environmentalists and many experts are urging the White House to update its social cost of carbon (SCC) metric to significantly boost the estimated benefits of GHG controls, while also arguing the tool should be broadly used in procurement, project reviews and other decisions in addition to crafting climate and other rules.

California and Department of Interior (DOI) officials are providing new details about their plans to consider offshore wind power project proposals off the Golden State’s coast to help meet President Joe Biden’s ambitious U.S. targets for the zero-carbon renewable energy source.

EPA is evaluating whether to expand its long-planned proposal to designate the two most studied per- and polyfluoroalkyl substances (PFAS) as “hazardous substances” under the Superfund law to include a small number of additional PFAS, according to an agency source, an approach that appears to fall short of calls from state officials and EPA alumni, who have called for a broader expansion.

Industry officials are urging EPA to issue this year its long-planned proposal for regulating nitrogen oxide (NOx) emissions from heavy-duty trucks so it can align with a new California requirement for model year 2027, amid conflicting statements from officials that the rule is both a “high priority” and a “long-term” action with no specific deadline.
