Group Against Smog & Pollution

Gov. Josh Shapiro this week announced that the Pennsylvania Department of Environmental Protection (DEP) was seeking final court approval of a consent decree that will allow two generating stations in the Commonwealth to reopen and operate through 2032.   The Keystone and Conemaugh Generating Stations are both coal-fired power plants having the same operator. Keystone is in Armstrong County and Conemaugh is in Indiana County. Both plants had been slated to close at the end of

Standing shoulder-to-shoulder with local families and environmental advocates, the   Group Against Smog and Pollution (GASP)  on Monday attended a public hearing to challenge the installation permit for the EQT Leto Well Pad and Dehydrator in West Deer Township. GASP joined our partners at   Concerned Residents of West Deer (CROWD) , a dedicated group of neighbors who have spent years fighting to protect their community from heavy industrial shale gas operations in residentia

An enforcement action by the Allegheny County Health Department (ACHD) serves as a stark reminder that public health regulations aren't optional—even for state agencies. Here’s what happened: During a routine inspection in April 2025, ACHD representatives visited the I-376 Bridge over Boyce Road and determined that while the site already held a permit for sandblasting structural steel, crews were also performing unpermitted abrasive blasting on rusted rebar for concrete repai

The Allegheny County Health Department (ACHD) has issued a $7,140 civil penalty against NCP Carbon for repeated air quality violations and failure to report equipment breakdowns in 2025. Located in Jefferson Hills, the facility specializes in carbon products, including carbon raiser, injection carbon, and metallurgic coke. According to a March 9 ACHD enforcement order, between June and October 2025, department representatives documented several instances of excess emissions o

The Avonworth School District and one of its contractors are facing a $5,850 fine for asbestos abatement-related violations stemming from a 2025 roof replacement project at the high school.   According to a March 9, 2026, enforcement order issued by the Allegheny County Health Department (ACHD) and obtained by GASP through a public records request, the district and Triangle Roofing Corp. failed to provide the required asbestos survey prior to renovations at Avonworth High Sch

Remember that breakdown at U.S. Steel’s Clairton Coke Works this past January - the one that prompted the Allegheny County Health Department to issue this public statement? Because a GASP public records request has revealed new information: That the breakdown resulted in a demand for $10,000 in stipulated penalties against U.S. Steel. Why? Because of provision in a high-profile 2021 consent decre e  reached between the company, our friends at PennEnvironment, and the Alleghen

Ethylene oxide is a cancer-causing hazardous air pollutant that is used to sterilize medical products, among other things – we’ve blogged about ethylene oxide pollution several times .    Because the U.S. Environmental Protection Agency (EPA) has moved the sticks on regulating ethylene oxide pollution yet again , it’s time for another update.   EPA on March 17 published a proposed rule and reconsideration of its April 5, 2024 Final Rule that revised the National Emission Stan

Some abysmal news to share: As of this week, the Mon Valley has experienced 34 hydrogen sulfide (H₂S) exceedances so far in 2026.  To put that into perspective, during this same period last year, we were looking at just 14.  For the uninitiated: Hydrogen sulfide is an air pollutant with an unmistakable rotten egg odor that all-too-often blankets the Mon Valley.  While the Allegheny County Health Department (ACHD) tracks it, the health and quality-of-life impacts are more tha

Last July, we blogged  about a proposal by the U.S. Environmental Protection Agency (EPA) to revoke its 2009 finding that greenhouse gas emissions from new motor vehicles in the United States endangered the public health and welfare by contributing to the global warming crisis.   Known as the 2009 Endangerment Finding, it was the predicate for EPA’s increasingly stringent regulation of new motor vehicles’ greenhouse gas emissions, by which EPA intended to force the electrific

The Aug. 11, 2025 explosion at the Clairton Coke Works killed two, injured a dozen more, and rocked an entire community. In its wake was special air quality monitoring , a Chemical Safety Board investigation , and, most recently, a $118,000 fine from OSHA.   Then came the biggest news yet: A pair of wrongful death suits had been filed against U.S. Steel and two other companies.   While GASP is not affiliated with the cases and has no special knowledge of them, staff reviewed

Last June, we blogged about EPA’s proposal to repeal revisions to the National Emission Standards for Hazardous Air Pollutants (NESHAPs) for coal-fired electric generating units (EGUs).    Those revisions were made in May 2024.   Here’s an update, which should not come as a surprise: on Feb. 24, the Environmental Protection Agency (EPA) published a final rule that did in fact repeal the May 2024 NESHAPs for coal-fired EGUs , on the same bases that were proposed when we last

The Pennsylvania Department of Environmental Protection (DEP) published notice of its intent to issue a Plan Approval to Shell Chemical Appalachia LLC for modifications to the company’s ethane cracker in Monaca, Beaver County - with plans for a public hearing April 7. Specifically, the Plan Approval would: authorize Shell to modify flares that it uses to control air pollution at the Facility, as required by new federal regulations authorize Shell to install new equipment in t

The U.S. Occupational Safety and Health Administration (OSHA) has fined U.S. Steel $118,000 for safety violations stemming from the deadly August explosion at the Clairton Coke Works. OSHA documents show that the company was cited 10 times - nine of those were related to subpar safety procedures and employee training, and one was for failing to provide the agency with required reports as required. The fines were first reported by the Pittsburgh Tribune Review . Additionally,

There’s been yet another equipment breakdown at U.S. Steel’s Clairton Coke Works facility, the Allegheny County Health Department (ACHD) announced in a press release Thursday. Here’s what the release said: According to the release, ACHD received a call from U.S. Steel regarding a breakdown of pollution control equipment at Clairton Coke Works. A breakdown happens when equipment isn't working properly and releases more pollution than normal. This can happen when equipment fail

GASP Executive Director Patrick Campbell asked the board to use its authority to push ACE to refresh appointments to the Air Advisory Committee.

As we continue to advocate for a cleaner, safer Mon Valley, the Group Against Smog and Pollution (GASP) is keeping a close eye on the fallout from the deadly August 2025 explosion at U.S. Steel’s Clairton Coke Works . In case you missed it, the U.S. Chemical Safety and Hazard Investigation Board (CSB) published an interim report following that issued interim safety recommendations to the company. You can read the entire document here  (and we totally recommend that you do). F

Yinz smell that?! That tell-tale stench of rotten eggs? You’re not smelling things: Concentrations of hydrogen sulfide (or H2S for short) are sky-high in and around the Mon Valley today. And you’re not alone in your suffering - social media and Carnegie Mellon University’s Smell Pittsburgh app lit up with complaints starting overnight Monday and continuing into the afternoon Tuesday: For the uninitiated: H2S is a toxic gas that occurs both naturally (from sources such as sw

Bad news to report today, friends. Here’s what’s going on: As you may recall, back in July, we blogged about the EPA’s   proposal to postpone compliance deadlines  in the revised National Emission Standards for Hazardous Air Pollutants for integrated iron and steel manufacturing facilities (the II&S NESHAPs), including U.S. Steel’s Edgar Thomson Works in Braddock.  GASP also   spoke out against  the proposed postponement in September. Unfortunately, but not surprisingly, EPA
