House energy committee approves bill to delay ozone NAAQS

The House Energy & Commerce Committee June 28 voted to approve H.R. 806, a bill that would delay by eight years the implementation of EPA's tougher 2015 ozone national ambient air quality standard (NAAQS) and make far-reaching changes to the Clean Air Act that Democrats warn will harm public health. Committee members voted 29-22 along party lines to approve the bill, as amended by environment subcommittee Chairman Rep. John Shimkus, (R-IL), clearing the way for a House floor vote. Shimkus'...

Carper Weighs Bipartisan Letter Seeking Talks On 2030 Vehicle GHG Rules

Sen. Tom Carper (D-DE) is said to be in the early stages of developing a bipartisan letter that could urge the Trump administration to negotiate light-duty vehicle greenhouse gas and fuel economy limits out to 2030 -- potentially offering an eased political path to giving automakers some flexibility in current rules through 2025 in exchange for continued progress in later years. Carper, the top Democrat on the Senate environment committee, acknowledged work on the effort in June 28 remarks to...

Pruitt Touts Vehicle GHG Rules As 'Progress' On CO2 Despite Rollbacks

EPA Administrator Scott Pruitt is touting the Obama administration's light-duty vehicle greenhouse gas standards as the “greatest progress” EPA has made with respect to reducing carbon emissions, comments that appear paradoxical as the Trump administration works to potentially relax those standards and seeks to more broadly undermine climate policy efforts. “I think the greatest progress we have made as an agency has really been honestly with mobile sources,” Pruitt said, referring to joint Department of Transportation fuel economy and EPA...

EPA sends NO2 NAAQS proposal for OMB review

EPA has sent for White House Office of Management & Budget (OMB) pre-publication review its proposal on whether to revise the nitrogen dioxide (NO2) national ambient air quality standard (NAAQS) last updated in 2010, with the agency facing a looming July 14 settlement agreement deadline for publishing the proposed rule. OMB received the rule June 26 according to the White House's website, and while interagency review typically takes 90 days it can take less time for some rules -- so...

States, Environmentalists Fault EPA Over Secrecy With Ozone 'Task Force'

Clarification Appended Some states and environmentalists are faulting EPA's secrecy over the work of its internal “task force” crafting a report to Congress on how to ease implementation of agency ozone standards, with states saying they are excluded from the effort and environmentalists fearing that the report will lead to weakening of the standards. “I have heard nothing out of the task force and not even certain who is on it.
