Last year, many of us signed with relief when the U.S. Environmental Protection Agency (EPA) unveiled critical revisions to the National Emission Standards for Hazardous Air Pollutants (NESHAPS) for Integrated Iron and Steel Manufacturing Facilities.  These updates, which required fence line monitoring of dangerous pollutants like benzene, were a hard-won victory for cleaner air and public health, directly impacting facilities like U.S. Steel’s Edgar Thomson Works right here in our region. These regulations were designed to provide concrete, enforceable limits on harmful emissions, with clear compliance deadlines set. They were meant to protect us. But now, the EPA has chosen to put corporate profits over our well-being. Earlier this month, the EPA published an interim final rule that unacceptably delays these vital compliance deadlines until April 3, 2027.  This decision is a direct undermining of the progress we fought for. The EPA's justifications – vague claims of "infeasibility" provided by industry and a flimsy plea for "consistency" regarding fence line monitoring – simply do not hold up against the stark reality of the inevitable environmental and public health consequences. While saving industrial polluting facilities an estimated $3.3 to $3.5 million, frontline communities will be dealt an additional 120 tons of hazardous air pollutants  (also known as HAPs) being emitted that would have been avoided under the original deadlines.  Please let that sink in: An additional 120 tons of cancer-causing agents, respiratory irritants, and other toxins will continue to pollute our air, prolonging exposure for communities already disproportionately burdened by industrial pollution. It's clear that Trump’s EPA, an agency supposedly committed to environmental protection, is prioritizing budget considerations of polluting industries over the lives and health of frontline communities (like Clairton, Braddock and so many others here locally). While we recognize that this public comment period might ultimately be performative – a box the administration feels compelled to check – it is absolutely crucial that our vehement opposition to this, and all other rollbacks of regulations meant to protect our health and environment, is put on the record. Our collective outcry creates a formidable record of dissent, which is essential for future advocacy, legal challenges, and continued resistance. But please know the clock is ticking. EPA is accepting comments on this interim final rule through Aug. 1 . We want to make it as simple as possible for residents to join us in our dissent. All you have to do is click here to submit your concerns .  When you submit your comment, keep these points in mind: Be clear, concise, and articulate your strong disagreement.

Another day, another environmental regulatory rollback announced by Trump’s EPA: The agency last week announced it will extend the compliance deadlines related to coal ash. Here’s what the regime said in a press release: "Today's actions provide much needed regulatory relief for the power sector and help deliver on the commitments outlined on the greatest day in deregulatory history to unleash American energy, lower costs for Americans, and work hand-in-hand with our state partners to advance our shared mission."   But wait there’s more (spoiler - it’s all bad news): EPA is also extending the groundwater monitoring requirements for operators of coal combustion residual management units until at least Aug. 8, 2029. Why is this happening? It’s part of the systematic dismantling of a bevy of regulations promulgated to protect our environment and public health. This past spring, EPA committed to taking swift action on coal ash , including state permit program reviews and updates to the coal ash regulations. “This is an infuriating continuation of a pattern where vital regulations, crafted to shield our communities and environment from toxic pollution, are being systematically gutted,” GASP Executive Director Patrick Campbell said. “We've seen this abandonment of duty far too many times, and it forces us to ask: Is EPA leadership even committed to protecting the public, or have they truly abandoned us to the whims of polluting industries?” EPA will accept comments on the companion proposal for 30 days after publication in the Federal Register. This final rule will be effective six months after publication in the Federal Register unless EPA receives adverse comments.

GASP and our friends at the Climate Action Campaign hosted a press conference at Sol Patch Garden in Braddock to sound the alarm over recent EPA regulatory rollbacks and demand accountability in their wake. GASP Executive Director Patrick Campbell was flanked by Braddock resident and activist Edith Abeyta, Pittsburgh City Council Member Erika Strassburger, and registered nurse Kathryn Westman - all gave powerful comments demanding EPA uphold its mission and stop the roll backs. Little bit of background: In the past month, EPA has announced its intent to roll back a host of environmental regulations (some of which effect U.S. Steel's Mon Valley Works facilities among others), which will have an inevitable impact on the Pittsburgh region. "Braddock has lived in the shadows of major pollution sources for more than a century, and the health and well-being of our community has suffered. There is a better way. It's time for stronger air pollution standards that protect our friends and family, the people we love," Abeyta said at the press conference. We agree, Edith! And here are the comments GASP Executive Director Patrick Campbell shared: Good morning. My name is Patrick Campbell, and I'm here today representing the Group Against Smog and Pollution. For decades, GASP has been on the front lines, fighting for the right to breathe clean air in our communities. Today, I stand before you with a sense of urgency, because that fundamental right is under threat. We are witnessing a dangerous trend: The systematic rollback of crucial environmental protections by the Environmental Protection Agency. These regulations, regulations like the Coke Oven Emissions Standards, limiting greenhouse gas emissions from power plants, and the mercury and air toxics standards all of which were crafted over years, based on sound science and public health imperatives and input, are being dismantled. These aren't just bureaucratic adjustments; these are decisions that will have real, tangible, and potentially devastating consequences for our health and our future. Right here in Braddock, the delayed implementation of the revised National Emission Standards for Hazardous Air Pollutants for Integrated Iron and Steel alone will allow U.S. Steel’s Edgar Thomson Works to emit greater amounts of hazardous air pollutants between now and July 3, 2027, than it otherwise would have. Let's be clear: the air quality regulations being weakened were designed for a reason. They were put in place to limit the very pollutants that cause asthma attacks in our children, trigger heart disease in our seniors, and contribute to a host of other respiratory and cardiovascular illnesses. When the EPA loosens standards on emissions from power plants or industrial facilities, it means more particulate matter in our lungs, more ozone damaging our airways, and more toxic chemicals contaminating our neighborhoods. The human cost of this deregulation is immense. We're talking about increased emergency room visits, more missed school days, and a greater burden on our healthcare system. For those already struggling with chronic conditions, these rollbacks are not just concerning; they are a direct threat to their quality of life - and in some cases - their very survival. We cannot, and must not, sacrifice public health for short-sighted economic gains. Full stop. Because who bears the brunt of these rollbacks? It is our frontline neighbors. These neighbors live closest to industrial facilities, major roadways, and other sources of pollution, and have borne the greatest share of environmental burden. These rollbacks will only exacerbate that injustice. So, what can we do? We certainly cannot afford to be silent. We must raise our voices and demand accountability from our elected officials and from the EPA. Contact your representatives, share your stories, and let them know that clean air is not a luxury; it is a necessity, a right, and a non-negotiable foundation for healthy communities. Thank you.

Last week, the U.S. Environmental Protection Agency (EPA) announced its plan to delay full implementation of the revised National Emission Standards for Hazardous Air Pollutants (NESHAPs) for Integrated Iron and Steel making facilities.   As a result, U.S. Steel’s Edgar Thomson Works will be authorized to emit greater amounts of hazardous air pollutants between now and July 3, 2027 , than it otherwise would have.  We blogged about that   here . Yesterday, EPA announced that it also plans to delay full implementation of the revised NESHAPs for Coke Ovens and Coke Oven Batteries, which will impact both U.S. Steel’s Clairton Coke Works and Cleveland Cliffs’ Monessen Coke Works.   We blogged about those revised NESHAPs   here , when they were proposed.   Specifically, EPA plans the following delays to these rules that will apply at Clairton and Monessen: The requirement that coke works install and operate fenceline monitors to detect benzene levels will be delayed from July 7, 2025, to July 5, 2027; New limits for emissions of hazardous air pollutants from coke oven pushing, quenching, and battery stacks will be delayed from January 6, 2026 to July 5, 2027; and New limits on leaking coke oven doors, lids, and offtake piping will be delayed from July 7, 2025, to July 5, 2027. Speaking broadly, EPA is justifying the delays based on assertions that compliance with the regulations will in many instances require modifying the facilities, which in turn requires engineering, permitting, and construction of new equipment or controls, all of which can take significant time.   Those assertions were made by industry groups and bolstered by materials that they submitted in connection with petitions for reconsideration of the rules. “As with the NESHAPs for Integrated Iron and Steel making facilities, EPA has estimated an industry-wide cost savings associated with the delays, of between $4.2 and $4.4 million,” said GASP Senior Attorney John Baillie.  “In contrast, EPA did not provide an estimate of how much additional pollution will result from the delays.” You can submit comments on EPA’s plan to delay implementation of these standards and limits for emissions of hazardous air pollutants from coke ovens through August 7, 2025, at   https://www.regulations.gov .  Identify your comments by two Docket ID Numbers (EPA-HQ-OAR-2002-0085, for Coke Ovens: Pushing, Quenching, and Battery Stacks, and EPA-HQ-OAR-2003-0051, for Coke Oven Batteries) and reference those docket numbers in your comments.

Last week, we   blogged  about the Environmental Protection Agency’s (EPA) proposed revocation of limits on coal-fired electric generating units’ (EGUs) emissions of hazardous air pollutants.   That isn’t all EPA has been up to.   On the same day EPA proposed to revoke limits on coal-fired EGUs’ emissions of hazardous air pollutants, it also published a   proposal  to eliminate all limits on fossil fuel-fired EGUs’ greenhouse gas emissions. That proposal would bring EPA’s regulation of EGUs’ greenhouse gas emissions back full circle to where it was 10 years ago, specifically, to no regulation of such emissions.   The Presidential administrations over the last 10 years have gone back and forth (and back and forth again) in their attempts to regulate, or not regulate, GHG emissions from EGUs.  Here is a timeline of the highlights of what EPA and the courts have done with respect to the regulation of EGUs’ GHG emissions.  See if you can follow: In 2015 , the EPA under President Obama promulgated New Source Performance Standards for yet-to-be-built fossil fuel-fired EGUs (the NSPS) and the Clean Power Plan for existing fossil fuel-fired EGUs.  The NSPS would have required new fossil fuel-fired EGUs to use carbon capture and sequestration to limit their GHG emissions.   The Clean Power Plan would have required the states to regulate greenhouse gas emissions by shifting generating capacity from fossil fuel-fired EGUs to renewable generation of electricity.   Notably, the EPA asserted that it had the authority to promulgate the NSPS and the Clean Power Plan under section 111 of the Clean Air Act based on its determination that fossil fuel-fired EGUs were a significant source of GHG emissions and its 2009 determination that GHG pollution endangered the public health and welfare.  Section 111 requires EPA to regulate emissions from a category of sources if such emissions “cause[], or contribute[] significantly to, [dangerous] air pollution.” In 2018 , the EPA under President Trump proposed to revise the NSPS for fossil fuel-fired EGUs by eliminating the Clean Power Plan’s carbon capture and sequestration requirement. In 2019 , the EPA under President Trump repealed the Clean Power Plan and replaced it with the Affordable Clean Energy Rule.   The Affordable Clean Energy Rule would have required new coal-fired EGUs to reduce GHG emissions by improving combustion efficiency and would also have eliminated the requirements that would have required the states to shift generation capacity from fossil fuel-fired EGUs to renewable generation of electricity. In 2021 , the U.S. Court of Appeal for the District of Columbia Circuit vacated both the Affordable Clean Energy Rule and the Trump Administration’s repeal of the Clean Power Plan.  In 2022 , in the case West Virginia v. EPA, the U.S. Supreme Court reversed the D.C. Circuit’s decision to vacate the repeal of the Clean Power Plan, determining that section 111 of the Clean Air Act could not be read so expansively as to give EPA the power to restructure the United States’ market for electricity.   Following that reversal, the D.C. Circuit entered an order which would have reinstated the Affordable Clean Energy Rule, which never went into effect because… In 2024 , the EPA under President Biden responded to the Supreme Court’s decision by promulgating the “Carbon Pollution Standards,” which repealed the Affordable Clean Energy Rule.   The Carbon Pollution Standards also would have required coal-fired EGUs to use carbon capture and sequestration after January 1, 2032, and would have imposed strict limits on GHG emissions from natural gas- and oil-fired EGUs. And finally, on June 17 , the EPA (once again under President Trump) proposed not just to repeal the “Carbon Pollution Standards,” but also all GHG emission standards for fossil fuel-fired EGUs.   In this proposal, EPA departs from the interpretation of section 111 of the Clean Air Act that it used in 2015 to assert its authority to regulate EGUs’ GHG emissions.  Rather than focusing on the volume of those emissions alone to determine whether or not they contribute “significantly” to dangerous air pollution, EPA proposes to focus on the impact that regulating the emissions would have on the public health and welfare.   Specifically, EPA asserts that because GHG pollution is a global problem that EGUs in the United States contribute to in only a small (and shrinking) part, and because its regulation of American EGUs’ GHG emissions would have no significant effect on GHG levels in the atmosphere, those emissions do not cause or significantly contribute to dangerous levels of GHG pollution, and it is not obligated to regulate them under Clean Air Act Section 111.    Which returns the status quo to where it was in 2015.   “If you are thinking that EPA’s assertion regarding the scope of its regulatory authority, if taken as true, would mean no regulation of any GHG emissions under the Clean Air Act as it is currently written, you may very well be right,” said GASP’s Senior Attorney John Baillie. “Moreover, if you’re wondering why no one in Congress or the White House thought to amend the Clean Air Act at any time between 2015 and now to clarify how GHG emissions from EGUs and other sources should be regulated – there have been several years where one party or the other controlled both Congress and the White House – so are we.  It is a remarkable failure.” It is just about certain that EPA will promulgate a final rule regarding EGUs’ GHG emissions based on the latest proposal in the upcoming months or years, and similarly certain that the basis of the final rule will be challenged in court.  We will follow along and keep you posted on that.  In the meantime, EPA is accepting comments on its proposed rule through Aug. 7.   You can submit comments at   https://www.regulations.gov .   Submit your comments under Docket ID No. EPA-HQ-OAR-2025-0124, and reference that docket number in your comments themselves.

Last year, we   blogged  about the U.S. Environmental Protection Agency’s (EPA) revisions to the National Emission Standards for Hazardous Air Pollutants for Integrated Iron and Steel making facilities. Those revisions imposed new emission standards and limits, mostly on the facilities’ previously unregulated fugitive emissions of hazardous air pollutants.  One facility in our region - U.S. Steel’s Edgar Thomson Works - is subject to these regulations. On July 3, EPA published an interim final rule that delays compliance deadlines for those revised emission standards and limits.  Specifically, EPA is pushing compliance deadlines which would have fallen on either April 3, 2025, or April 3, 2026, back to April 3, 2027, for these new standards and limits: Work practice standards designed to reduce emissions of particulate matter (PM) from unplanned bleeder valve openings The opacity limit on emissions from unplanned bleeder valve openings Work practice standards designed to reduce emission from blast furnace bell leaks The opacity limit on emissions from slag processing and handling; and A requirement to install and operate fenceline monitors to track chromium levels in the ambient air. Generally speaking, EPA is pushing back the compliance deadlines for the first four standards above based on new information ( provided by industry ) that purports to show that compliance by the original deadlines in 2025 and 2026 was not feasible.   In contrast, EPA is delaying the compliance deadline for the fenceline monitoring requirement “[f]or consistency,” not because of infeasibility. “According to EPA, the delay will save the nine facilities between $3.3 and $3.5 million,” said GASP’s Senior Attorney John Baillie, “However, the delay will also result in emissions of 120 tons of hazardous air pollutants that would have been avoided had the original deadlines been enforced. This seems like the wrong trade-off for EPA to make.” EPA is accepting comments on the revised compliance dates only through Aug. 1. You can submit comments at   https://www.regulations.gov .

While our core work involves advocacy, watchdog efforts, and public education, did you know a vital component of our success lies in our robust partnerships with academia? It’s true - we regularly collaborate with bright minds from local universities like the University of Pittsburgh, Carnegie Mellon University, Chatham University, and more, integrating their research and analytical skills into our ongoing fight for cleaner air. These collaborations are deeply embedded in our strategic work, offering students invaluable real-world experience while providing GASP staff with fresh perspectives and enhanced capacity to tackle complex air quality challenges.  From in-depth air quality research to policy analysis and developing innovative watchdog tools, academia plays a critical role in advancing our goals. Visualizing Air Quality Violations at Title V Facilities in Allegheny County  This past spring, we had the privilege of working with a talented group of students from the University of Pittsburgh School of Computing and Information on a data analytics project that looked at air quality violations from the polluting facilities over the past five years. The students took on the challenge of visualizing this complex data. They compiled information from various public records, regulatory filings, and news reports, then transformed it into a visual representation.  This kind of data visualization can be incredibly powerful, allowing community members, policymakers, and even fellow advocates to quickly understand the scope and history of air pollution issues.  In order from left to right (all seniors): Jiri Palayekar (Majors: Information Science and Psychology), Abby Swan (Major: Data Science), Areej Mohsin (Major: Data Science), Dhwani Kanani (Major: Data Science), Ankita Raj (Major: Data Science), Luke Daniel (Majors: Data Science and Computer Science). We thank them so much for their work, which you can check out here . Collaboration is at Our Core This project is just one example of how academic partnerships are woven into the fabric of GASP's work.  We believe that fostering these connections enriches both the students' educational journeys and our capacity to make a tangible difference in our region's air quality. Students from various disciplines – environmental science, public policy, data analytics, public health, and more – find opportunities to apply their theoretical knowledge to real-world problems with direct community impact. “These collaborations are not just about research; they're about building the next generation of environmental leaders and providing them with the practical experience needed to drive change,” GASP Executive Director Patrick Campbell said. “We benefit from their enthusiasm, their access to cutting-edge research methodologies, and their fresh analytical approaches. In return, we offer them a chance to contribute meaningfully to a cause that potentially affects every breath we take.” Looking Ahead: Partner with Us This Fall! As we look towards the Fall 2025 semester and beyond, GASP is eager to expand these partnerships. If you are a professor or a student at Pitt, CMU, Chatham, or any other academic institution in the region with an interest in environmental health, public policy, data science, or related fields, we invite you to reach out to us.  Let's explore how we can collaborate to make Southwestern Pennsylvania a healthier place for everyone to breathe.

Can we get a drumroll, please? Because we’re thrilled to unveil our Fresh Voices - Oral History Project , which engaged high school students and GASP staff in documenting the lived experiences of Allegheny County residents concerning local air quality.  Through interviews, we are collecting firsthand accounts to create an oral history archive that illuminates the historical and personal dimensions of air quality in the region. Over the past several months, our Fresh Voices for Clean Air participants had the privilege of sitting down with some truly incredible people – from Pittsburgh public broadcasting legend Rick Sebak to long-time residents who have witnessed firsthand the changes in our air and passionate environmental activists dedicated to making a difference.  Each conversation provided unique and powerful insight into the realities of living in an area with generational air quality issues, revealing both the challenges faced and the enduring hope for a healthier environment. Why Oral Histories? It’s simple: We believe real stories have the power to educate, inspire, and drive change. While scientific data is absolutely crucial, it's the personal narratives that truly bring serious public health issues to life.  By helping to curate these stories, we hope to: Preserve local history Humanize air quality issues and Empower community voices Inform future advocacy A Heartfelt Thank You to Our Participants! We would be remiss if we didn’t stop here and extend a HUGE thank you to every single person who has participated in this year’s Fresh Voices project so far.  “Your willingness to open up and share your experiences, memories, and insights has been truly invaluable,” GASP Project and Education Manager Laura Kuster said.  Through the process of curating these stories, our Fresh Voices students not only learned more about the decades-long fight for clean air - they also honed research, interviewing, video, and photography skills. Take A Listen! Go ahead, grab your headphones and get comfy and take a listen.

Earlier this year we blogged about how the U.S Environmental Protection Agency (EPA) provided exemptions from several National Emission Standards for Hazardous Air Pollutants (NESHAPs) that became effective in 2024.   We even predicted that the exemptions were a prelude to those NESHAPs being repealed. Unfortunately, sometimes our predictions come true.   The EPA on June 17 published a proposed rule that would repeal amendments that were made in 2024 to strengthen NESHAPs for coal-fired electric generating units .   Most significantly, EPA has proposed the repeal of a standard for emissions of filterable particulate matter from coal-fired EGUs. Filterable particulate matter is a surrogate measure for all metallic hazardous air pollutants (excluding mercury) emitted by coal-fired EGUs.   The 2024 NESHAPs reduced the emission limit for filterable particulate matter from coal-fired electric generating units from 0.03 pounds per million BTUs down to 0.01 lbs.   And there will be impacts here in our corner of the Keystone State - there are still five coal-fired EGUs operating in western Pennsylvania.   Each of these facilities would have  had to reduce its emissions of filterable particulate matter from 0.03 lbs/MMBtu to 0.01 lbs/MMBtu to meet the emission standard that EPA proposes to repeal.   The basis for the proposed repeal? The cost for facilities to comply with the filterable particulate matter emission limit. EPA can take cost-effectiveness into account when it reviews new control technologies for hazardous air pollutants, as it must every eight years under the Clean Air Act.   In its proposed rule, EPA estimates that the cost of measures required for some plants to comply with the to-be repealed standard is $10.5 million per ton of non-mercury HAPs, which exceeds the EPA’s threshold for cost-effectiveness. That exceeds the EPA’s threshold for cost-effectiveness, based on proposed emission standards that were rejected in 2015 and 2020: In 2015, EPA determined that emission controls for petroleum refineries that would have removed fPM at the cost of $10 million per ton were not cost effective, and in 2020 EPA determined that emission controls for iron and steel manufacturing facilities that would have removed fPM at the cost of $7 million per ton were not cost effective.  “EPA’s discretion to make determinations like this is pretty much unlimited under the Clean Air Act, and underscores just how important who controls the administrative branch in Washington is to how much pollution is in the air we breathe,” said GASP’s Senior Attorney John Baillie.      As part of its proposed rule EPA is also asking to repeal a requirement that coal-fired electric generating units demonstrate compliance with the filterable particulate matter emission standard by using a continuous emission monitoring system and a standard for mercury emissions from those that burn lignite (almost all of which are located in the western United States). EPA is accepting comments on the proposed rule through August 11.   EPA prefers that comments be submitted at https://www.regulations.gov .   Submit your comments under Docket ID No. EPA-HQ-OAR-2018-0794, and reference that docket number in your comments themselves. GASP continues to follow this issue closely and will keep you posted.
