EPA launches new ICR for ethylene oxide air rule

EPA is launching a new request for information from commercial sterilization facilities on their use of the solvent ethylene oxide (EtO), as the agency prepares to issue a possibly tougher regulation to curb emissions of the chemical that EPA now believes is significantly more carcinogenic than previously thought. In a May 10 Federal Register notice , EPA announces it will take comment for 30 days on a new Information Collection Request (ICR) to support its technology review of the...

Awaiting Biden Order, EPA Takes Steps To Weigh Climate Finance Risks

As the Biden administration readies a new executive order to address the financial risks posed by climate change, EPA is beginning to consider both the physical and transition risks companies face, including launching talks with the Securities and Exchange Commission (SEC), which is poised to write climate risk disclosure rules. In addition, officials are also considering asking agency financial advisors for assistance on the issue. “Climate risk is an interesting concept,” Al McGartland, director of EPA’s National Center for Environmental...

Denka defends emissions compliance at Louisiana facility

Denka Performance Elastomer (DPE), which produces chloroprene rubber, is defending the emissions performance of a facility it owns in Louisiana in response to a petition from civil rights groups asking EPA to require the company to cut emissions of two air toxics that the organizations say are harming nearby communities. The groups, representing the majority Black community of St. John the Baptist Parish, on May 6 petitioned EPA to use emergency Clean Air Act powers to “abate the imminent and...

EPA Clashes With OIG Over Call To Tighten Emission Rules For Two HAPs

EPA is clashing with its Office of Inspector General (OIG) over a new OIG report that urges the agency to tighten its emissions rules for the hazardous air pollutants (HAPs) ethylene oxide (EtO) and chloroprene, rejecting what it sees as overly prescriptive rulemaking recommendations and avoiding any firm promise to tighten its regulations. The OIG in a May 6 report says EPA should issue risk-and-technology review (RTR) rules under the Clean Air Act’s (CAA) air toxics program to limit industrial...


CARB Floats Tough ZEV Mandate For MY26-35, Boosting Federal Push

California air regulators have unveiled a long-awaited proposal to set aggressive zero-emission vehicle (ZEV) sales mandates for new passenger vehicles that would ramp up requirements to reach 100 percent ZEV sales by 2035, likely bolstering calls for the Biden administration to set federal emissions standards that achieve such a goal. During a May 6 virtual public workshop, staff with the California Air Resources Board (CARB) outlined details of their ZEV proposal for model years 2026-35, with the plan significantly curbing...

Rights groups seek stricter EPA regulation of industrial air toxics

Civil rights groups representing the majority Black community in Louisiana’s St. John the Baptist Parish are petitioning EPA to use its emergency Clean Air Act powers to abate risks the area faces from industrial emissions of air toxics, and also review and revise the agency’s existing regulations designed to curb the pollutants. The May 6 petition filed on behalf of the residents by the Lawyers’ Committee for Civil Rights Under Law, Earthjustice and the group Citizens of St. John asks...

Biden EPA Faces Pressure To End Debate On Regulating AFO Emissions

The Biden administration is facing pressure to resolve a long-running debate over whether and how EPA should regulate animal feeding operations’ (AFOs) emissions of hazardous gases, criteria air pollutants and the greenhouse gas methane, with some states and Congress grappling with either pursuing or blocking AFO air rules. EPA has never regulated AFO emissions under the Clean Air Act, despite longstanding pressure to do so from environmentalists. The agency has for more than a decade been studying emissions from various...


Study On Biomass’ Harms May Boost Industry Bid For CO2 Permit Waiver

Harvard researchers are detailing the adverse health impacts from burning biomass and other combustion fuels for power generation, findings that could bolster efforts by some agriculture industry groups who are asking EPA to exempt use of agriculture residues in non-combustion processes, such as bioplastics production, from greenhouse gas permitting. The May 5 study by Jonathan Buonocore and Parichehr Salimifard of the Harvard T.H. Chan School of Public Health and published in Environmental Research Letters found that wood and natural...

Ranchers’ lawsuit over coal plant will test EPA air permit policies

Ranchers in North Dakota are continuing their legal fight against a coal-fired power plant and the related coal mine that supplies it, filing a fresh Clean Air Act lawsuit that will likely test the willingness of the Biden EPA to defend Trump-era EPA policies on deference to states and “aggregation” of sources in air permitting. In their lawsuit filed April 29 in the U.S. Court of Appeals for the 8th Circuit, ranchers Casey and Julie Voigt seek to overturn a...

EPA gives confidential RFS waiver data to GAO

EPA is preparing to give an extensive trove of renewable fuel standard (RFS) data, including the confidential business information (CBI) of many refiners, to the Government Accountability Office (GAO), as part of a probe requested by lawmakers into the agency’s handling of RFS compliance waivers. In a Federal Register notice scheduled for publication May 5, EPA informs “obligated parties” under the fuels program -- refiners and importers of fuel -- of its intent to comply with the GAO request...


EPA Move To Scrap RFS Waivers Signals Stricter Policy On Exemptions

EPA’s recent request for a federal appeals court to scrap and remand last-minute renewable fuel standard (RFS) compliance waivers the Trump administration issued to refiner Sinclair signals the Biden administration is pursuing a stricter policy on RFS exemptions regardless of the outcome of a pending Supreme Court waiver lawsuit. RFS waivers are available to small refiners that can demonstrate “disproportionate” economic hardship from having to comply with the program’s annual targets for production of alternative and renewable fuels. In an...


Health Groups Push Epidemiologists For Overhaul Of EPA Advisory Panels

Public health groups are nominating epidemiologists, toxicologists and other experts to form the membership of EPA’s Clean Air Scientific Advisory Committee (CASAC) and Science Advisory Board (SAB) after Administrator Michael Regan dismissed both committees and sought submissions for a new slate of board members. And they, along with at least one former member of the Trump administration’s CASAC, are urging the agency to revive specialist subpanels of the air committee providing in-depth advice on reviews of national ambient air quality...




EPA Proposes Phasedown Program For Climate-Warming HFCs

EPA is using new statutory authority to propose a program that would significantly phase down production of climate-warming hydrofluorocarbons (HFCs) used as refrigerants and in other sectors, a move that will provide a major boost to the Biden administration’s climate efforts. The proposed rule , publicly released May 3, is notable because it represents the first time EPA has monetized the climate-related benefits of reducing HFCs, and the agency also conducted an environmental justice (EJ) analysis of the plan to...

EPA Sets Precedent With Plan To Exclude Most Of Maine From OTC Area

EPA is proposing to grant Maine’s petition seeking to exclude most of the state from the Ozone Transport Commission (OTC) region of Northeast and Mid-Atlantic states where tougher ozone controls apply than elsewhere, setting a legal precedent that other OTC areas might cite if they want to leave the regional body. In a notice slated for publication in the May 3 Federal Register , EPA says it will allow much of Maine to leave the 12-state OTC area because emissions...
