Refiners Eye Departing If California Seeks To Offset Lost Vehicle GHG Cuts

Some oil refiners are threatening to leave California if the state imposes new greenhouse gas limits on the sector to offset reductions lost as a result of the Trump administration's planned roll back of Obama-era GHG standards for light-duty vehicles, though one source says refiners should await any plan from the Golden State before taking action. “We knew they'd come after us,” one refining source says. “We know this is the holy grail for California and they will fight like...

EPA defends bid to dismiss suit over withdrawn glider rule waiver

EPA is defending its bid for a federal appeals court to dismiss litigation filed by environmentalists and several states over its since-withdrawn enforcement waiver for glider truck emissions standards, fighting efforts by the waiver's critics to keep the suit alive by saying critics' concerns about EPA reviving the waiver later are “speculation.” In an Aug. 9 reply filed in the U.S. Court of Appeals for the District of Columbia Circuit, the agency also reiterates earlier arguments that because it withdrew...

Citing Legal Flaws, States Urge EPA To Withdraw Or Clarify Science Rule

Citing significant legal flaws, state environmental agencies are urging EPA to withdraw or delay and clarify its proposed rule barring the use in major regulatory decisions of any science where the underlying raw data and models are not publicly available, arguing that the proposal is vague and the agency has not engaged with states on its content. Their calls for EPA to withdraw or significantly overhaul the controversial proposal lends weight to similar advocacy from a host of other groups,...




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. So this is the test for...
