EPA eyes February for proposing year-round E15 sales waiver

EPA is aiming to release its proposed rule authorizing year-round sale of 15 percent ethanol fuel (E15) by February, an agency spokesman says, with a goal of publishing the final version by June 1. E15 is currently prohibited for sale from June 1 until Sept. 15 due to federal fuel vapor pressure restrictions. EPA's proposal would lift Reid Vapor Pressure limits, imposed because of air quality concerns, and also reform the market for compliance credits under the renewable fuel standard...

Lifecycle Study Finds GHG Cuts From LNG Project, Warns Of Domestic Gas

A new study of the lifecycle greenhouse gas emissions from a proposed liquified natural gas (LNG) project to provide fuel for marine operations near Seattle finds that the effort would cut overall GHGs by displacing petroleum-based fuels, though the finding depends on the natural gas being sourced only from Canada. If, instead, the gas were to come from the United States, it could result in emissions increases because the GHG profile of domestic gas is much higher than official EPA...

Wyoming urged to shield oil and gas air controls from EPA rollback

Environmental groups are urging Wyoming regulators to clarify a pending proposal to control oil and gas emissions to ensure that their plan to require leak detection and repair (LDAR) inspections every six months from new and modified facilities is not undermined by EPA's proposed rollback of federal limits on methane. The issue is an example of how EPA's rollback of its 2016 new source performance standards (NSPS) is spurring renewed attention to state programs and where they could be called...

EPA Urged To Speed RMP Changes After Declining Appeal Of Delay Ruling

Chemical industry attorneys are urging EPA to accelerate its plan to undo Obama-era changes tightening the risk management plan (RMP) facility safety program, after the agency opted against appealing a court ruling that scrapped the Trump administration's delay of the revisions and reinstated looming compliance deadlines. Attorneys representing the chemical sector say that EPA faced an early October deadline for seeking rehearing of an U.S. Court of Appeals for the District of Columbia Circuit panel's Aug. 17 ruling, which vacated...

EPA Finalizes Rule Weakening Obama-Era Resins Manufacturing NESHAP

EPA has finalized a rule that weakens an Obama-era national emissions standards for hazardous air pollutants (NESHAP) rule for amino-phenolic resins manufacturing and is also delaying implementation of the softened rule, in response to petitions from resin products urging the Trump administration to revise the regulation. The final rule published in the Oct. 15 Federal Register completes reconsideration of the April 2014 risk-and-technology-review (RTR) rule, which tightened emissions limits originally set in a January 2000 rule setting maximum achievable...


EPA, California spar over 'counter' to vehicle GHG rollback

Acting EPA Administrator Andrew Wheeler is urging California to submit a counter-proposal to the Trump administration's proposal to freeze vehicle greenhouse gas and fuel economy standards after model year 2020, even as the state says federal agencies and automakers have not provided information necessary for any serious dialogue. The dynamic underscores some recent signs of an uptick in negotiating over the vehicle program, but with no signs of significant progress in averting a full-scale legal battle that could take years...

DOJ Plans To Renew Call For Supreme Court To Halt Youth Climate Case

The Department of Justice (DOJ) is planning to renew its call for the Supreme Court to halt a novel climate change case brought by 21 youth plaintiffs, just weeks before the long-pending and high-profile matter is scheduled to go to trail in a federal district court in Oregon. The high court this summer rejected a similar request as premature, but DOJ will argue that its forthcoming petition for a writ of certiorari is now ripe because the district court judge...

Environmentalists ask EAB to scrap Arizona gas utility's air permit

Environmentalists are petitioning EPA's Environmental Appeals Board (EAB) to scrap an Arizona county's air permit granted to a natural gas-fired power plant for installation of liquid fuel engines, claiming the permit is not “enforceable,” but the plant's operator and the county are fighting the case. In the case, In re: Tucson Electric Power Irvington/H. Wilson Sundt Generating Station , Sierra Club is asking EAB to reject the “minor source” air permit granted by the Pima County Department of Environmental Quality...
