California sets meeting on further ways to curb petroleum GHGs

In another response to EPA's proposal to roll back Obama-era vehicle greenhouse gas standards, the California Air Resources Board (CARB) has scheduled a workshop for later this month to discuss “opportunities for additional GHG reductions from petroleum transportation fuels.” The Aug. 20 meeting to be held in Sacramento was announced Aug. 10 , just days after CARB advanced a proposal to retain its current vehicle GHG rules through model year 2025 in the face of EPA plans to block or...

EPA Downplays Emissions Hike From Auto GHG Plan, But Faces Doubts

The Trump administration is acknowledging its plan to roll back vehicle greenhouse gas and fuel economy standards will boost emissions of conventional air pollutants that cause local health effects but argues such increases are modest, even as some are concerned the plan could make it more difficult for some areas to meet national air standards. While many state and other observers are still assessing the proposal's impacts, some are already raising the possibility that it could underestimate conventional pollution increases...


In 'Test,' Environmentalists Urge Wheeler To Break With Pruitt On Key Rules

Environmentalists are urging Acting EPA Administrator Andrew Wheeler to narrow or scrap a series of proposals that his predecessor Scott Pruitt championed before resigning last month, eyeing the agency’s coming decisions on science policy, climate regulation and other issues as key signs of whether the new acting chief will be “Pruitt 2.0.” “We know full well that some of the proposals that his predecessor started would be illegal if they were finalized as written.

The suit , filed Aug. 7 in the U.S. District court for the Northern District of California, claims the agency is violating a Clean Air Act mandate to review the various rules eight years after their...


EPA eases limits on 'climate-friendly' refrigerants

EPA is easing current restrictions on certain “climate-friendly” refrigerants for household refrigerators and freezers, even as the agency's broader policy in this area remains murky due to a prior adverse court ruling and inaction by the Trump administration on an international deal to limit chemicals that are potent greenhouse gases. The agency published a final rule in the Aug. 8 Federal Register to ease use conditions for three refrigerants under its Significant New Alternatives Policy (SNAP) program. The chemicals,...


EPA air chiefs warn Wheeler, Wehrum on rollbacks

Five former EPA air chiefs, including one who later became administrator and another who served as deputy administrator, are warning acting Administrator Andrew Wheeler and current air chief William Wehrum of their concerns about a host of regulatory rollbacks the agency is pursuing, particularly via the Office of Air & Radiation. “We worked for both [D]emocratic and [R]epublican administrations, and are proud of the progress this country has made toward cleaner air,” they wrote in an Aug. 8 letter ,...
