EPA gives environmentalists rare partial win in air permit challenge

EPA has given environmentalists a rare partial win in their challenge to a Clean Air Act permit for a Gulf Coast oil refinery by finding some terms of the permit were too ambiguous or weak, despite agency Administrator Scott Pruitt setting a higher bar for permit objections and deferring more to states on the adequacy of permits. Pruitt signed a May 1 order partially granting, but otherwise denying, environmentalists' petition for agency objection to the Title V permit of the...




Environmentalists Fight States' 'Burning' Air Plans Despite EPA's Approval

Environmentalists are fighting efforts by states to win EPA approval of emissions control plans for open or prescribed burning of land that aims to reduce likelihood of wildfires that are a mounting problem in the United States, though the agency is signaling its approval for such measures -- most recently approving Texas' plan. EPA on April 23 announced its approval to changes to the Texas state implementation plan (SIP) for Clean Air Act implementation, which apply to prescribed burning smoke...

Critics Doubt EPA Plan To Redact Confidential Data In Transparency Rule

Critics of EPA Administrator Scott Pruitt's proposal to require only publicly available research to justify regulatory decisions say agency plans to protect confidential information, such as personal data or trade secret studies, by redacting it are not adequate, will result in a host of adverse effects and will undermine agency decisionmaking. Much of the criticism comes from environmentalists and public health officials, who charge that redacting personal data is often not adequate to protect subjects' privacy and could discourage their...

EV Group Bolsters Call To Retain Vehicle Rules While Expanding Credits

An industry coalition that backs electric vehicles (EVs) is pushing back against draft Trump administration plans to freeze vehicle greenhouse gas and fuel economy standards at model year 2020 levels, floating an alternative plan to retain current GHG targets through MY25 and keep or expand an array of compliance credit “multipliers” to boost advanced EVs and other technologies. The suggestions from the National Coalition for Advanced Transportation (NCAT) build on the group's prior appeals to retain but modify the vehicle...


Refiners ask D.C. Circuit to force EPA review of RFS 'obligation point'

A coalition of refiners is pressing the U.S. Court of Appeals for the District of Columbia Circuit to force the agency to review and potentially shift the renewable fuel standard's (RFS) compliance “obligation point” from refiners to biofuel blenders, after the Trump administration last fall denied their petitions to change the mandate. In an April 27 opening brief filed with the U.S. Court of Appeals for the District of Columbia Circuit in Alon Refining Krotz Springs, et al. v. EPA...


Trump's NAAQS Overhaul Prompts Questions On Scope Of CASAC's Input

President Donald Trump's directive for EPA to overhaul and streamline the national ambient air quality standards (NAAQS) review process is prompting questions over how it might affect the Clean Air Scientific Advisory Committee's (CASAC) input on NAAQS, including new consideration of costs and possibly undermining some air science. CASAC is an independent group of experts that advises EPA on reviews of its six NAAQS for ozone, particulate matter and other criteria pollutants. The group assesses the latest science on criteria...
