Automaker Group Urges OMB To Float Obama GHG Limits, Wide Flexibility

The Alliance of Automobile Manufacturers is outlining a detailed set of regulatory changes it would like the Trump administration to consider in its planned rulemaking on vehicle fuel economy and greenhouse gas limits, including significant compliance flexibilities but also options that could preserve talks with California. Among the requests in an alliance letter to the White House that was recently made public in a regulatory docket is for EPA and the Transportation Department (DOT) to include a scenario with stringency...


EPA, Sierra Club appear close to deal on RFS study

EPA and the Sierra Club are asking a district court to continue to pause a renewable fuel standard (RFS) deadline suit the group brought for just 10 more days, suggesting the two sides may be close to inking a settlement despite Administrator Scott Pruitt's policy memo imposing steep hurdles before agency lawyers can sign such agreements. The suit in the U.S. District Court for the District of Columbia concerns EPA's failure to complete a congressionally mandated study of the environmental...

Wehrum touts air quality benefits from ending 'always in' MACT policy

EPA air chief William Wehrum says the agency's controversial decision to end the longstanding “once in, always in” policy that required facilities to meet strict air toxics limits regardless of whether they lowered emissions will have air quality benefits, pushing back on critics' claims that it will allow facilities to emit more air pollution. “Ultimately, this policy is going to produce emissions reductions,” he told a recent House Energy & Commerce Committee energy panel hearing. He argued that scrapping the...

EPA Region 9 Chief Suggests Section 177 States Vulnerable On GHG Rules

EPA's newly appointed chief for Region 9 is suggesting that the agency might advance an argument that states outside of California cannot adopt its passenger vehicle greenhouse gas rules, even though a dozen other states have already done so under a process outlined in the Clean Air Act. Under the air law, California can enforce its own vehicle emissions standards after receiving a waiver of federal preemption from EPA, which it has secured for its vehicle GHG rules through model...

SAB Group Seeks Science Review Of All Major Trump EPA Climate Rollbacks

Members of EPA's Science Advisory Board (SAB) are seeking to review the underlying science for virtually all of the Trump EPA's major rollbacks of Obama-era climate policies, with another SAB workgroup late last week offering the latest scathing pushback of administration plans to weaken two high-profile mobile source rules, as well as the social cost of carbon (SCC) metric. The new recommendations from a second workgroup, which the full SAB will consider at its meeting later this month, come after...

States Aim To Revive 2015 Ozone NAAQS Suit, Fearing No Reconsideration

States opposed to the Obama EPA's 2015 rule tightening the ozone air standard are asking a federal appeals court to revive currently stayed litigation over the standard, saying the Trump administration appears to have backed off possible plans to reconsider the standard and instead proceed with a regular Clean Air Act-mandated review of the limit. Citing reporting by Inside EPA , a coalition of 10 states tells the U.S. Court of Appeals for the District of Columbia Circuit...


Suppliers Seek 'Robust' Vehicle GHG Standards With Additional 'Flexibility'

Auto industry suppliers are detailing their call for the Trump administration to embrace “robust” vehicle greenhouse gas and fuel economy standards with more flexibility for automakers, urging agencies to formally seek comment on an “advanced technologies flexibility option” that would recognize California's “critical role” in limiting emissions and possibly prevent years of litigation over the program. The call, articulated in a May 17 letter to EPA and Department of Transportation (DOT) officials, is the latest move by auto suppliers who...

Shimkus Pushes RFS Reform Bill Despite Trump Deal On EPA-Led Changes

Rep. John Shimkus (R-IL), chairman of the energy committee's environment panel, says he is pushing ahead with long-running efforts to craft legislation overhauling EPA's renewable fuel standard (RFS) despite a deal brokered by the White House that will see the agency make several immediate administrative changes to the program. In a May 16 interview, Shimkus told Inside EPA that he will continue with the legislative bid because, “You really want to enshrine things in the law,” suggesting a need for...
