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.

As EPA gears up to reconsider Trump-era air quality standards, the agency has named new members of the Clean Air Scientific Advisory Committee (CASAC) who will advise it on key reviews of the particulate matter (PM) and ozone standards, setting up a panel that will be dominated by research scientists and chaired by a strong critic of the Trump administration’s “streamlined” review process.

EPA advisors are crafting ambitious goals for cleaner vehicles, fuels, goods movement and personal mobility in an upcoming report that could bolster efforts by Administrator Michael Regan to who has said he is looking to an “electric future” for road transportation.

An environmental attorney and a former EPA chemicals chief say TSCA’s text and EPA’s own response to comments on its novel rules on five persistent, bioaccumulative and toxic (PBT) chemicals show the rules cannot preempt state policies, opening the door for state regulators to set more stringent limits than the agency did.

East Coast air regulators say they are “in the dark” on how the Biden administration plans to address interstate pollution transport and are still waiting for officials to set a comprehensive policy on the issue, despite projections that the emissions will contribute to ozone exceedances in parts of the Northeast, including New York City, for years to come.

A federal appellate court in a precedent-setting decision has found that courts can review whether an EPA withdrawal of a proposed Clean Water Act (CWA) permit “veto” violated the Administrative Procedure Act (APA) but has left it to a lower court to determine whether a Trump EPA withdrawal of a proposed permit veto of the Pebble Mine was arbitrary and capricious.

Environmentalists are calling for a series of measures to strengthen environmental rules for the mining sector in response to the Biden administration efforts to bolster the domestic supply chain for rare earth minerals and other crucial materials needed for electric vehicle batteries and other low-carbon energy technologies.
