The proposed regulation will be reviewed by the Office of the Attorney General and a public comment and participation period will be announced at a later date. The vote in the EQB was 13 to 6. GASP lauded the approval. “Pennsylvania contributes a disproportionate amount of climate change-causing air pollutants in the United States – an issue that badly needs to be addressed,” GASP Executive Director Rachel Filippini said. “We applaud this first step. When you’re in a climate emergency, you must take decisive action.” Under the proposed regulation, electric power plants that emit carbon dioxide will be required to obtain credits compatible with other states in the Regional Greenhouse Gas Initiative (RGGI). Modeling from DEP shows that participating in RGGI will decrease climate change-causing carbon dioxide pollution as well as generate new jobs and reduce air pollution-related illnesses. “This is an important step for Pennsylvania’s efforts to combat climate change, which is already having and will continue to have a dramatic effect on Pennsylvania,” DEP Secretary Patrick McDonnell said in a press release. “This is incredibly important and we are looking forward to hearing from the people of Pennsylvania about this effort.” Electricity generation is one of the leading sources of carbon dioxide emissions in Pennsylvania, and the commonwealth is a leading emissions source in the country. The proposed regulation would reduce carbon emissions by an estimated 188 million tons between 2022 (when the regulation would go into effect) and 2030. In addition, DEP officials said other benefits of RGGI for Pennsylvania include: Reduce carbon emissions by 188 million tons Increase of more than 30,000 jobs Reduction of other air pollutants like SO2 and NOx Avoiding 639 premature deaths from air pollution-related health issues Editor’s Note: More information about RGGI can be found at www.dep.pa.gov/RGGI #CarbonMonoxide #SO2 #RegionalGreenhouseGasInitiative #RGGI #NOx #carbonemissions #DEP

GASP and several local environmental groups and nonprofit partners sent a letter this week to Allegheny County Chief Executive Rich Fitzgerald calling on him to take swift, aggressive action to improve local air quality – reminding him that in many cases, the lives of his constituents literally depend on it. The letter was sent as part of the Toxic Ten Week of grassroots actions calling on Fitzgerald to demonstrate his commitment to air quality improvement by stemming air pollution from industrial sources. For those who may be unaware, the Toxic Ten refers to 10 local facilities that together emit 70 percent of all air pollution reported in Allegheny County. Enough is enough. We need clean air now.

The payment was part of a consent order and agreement between Prism Response and the ACHD finalized Sept. 22. As part of the settlement, the company further agreed to withdraw its appeal of the underlying Sept. 21, 2018 administrative order. That order called for Prism to pay a $20,770 civil penalty, about $7,000 of which was assessed for “intentional or reckless conduct” related to Prism’s response and water damage remediation work following a fire at the Coraopolis-based Sheraton Hotel in May 2017. Prism had disputed the “nature and extent” of those allegations, maintaining that it had not conducted any asbestos abatement or encapsulation work at the hotel, and cooperating as ACHD conducted a full investigation. The company provided ACHD with what health department officials deemed a “significant amount” of additional information. As a result of those disclosures, ACHD agreed to remove the penalties assessed for intentional and reckless acts, determining that “the findings in the administrative order are not representative of the full facts and actions of Prism,” according to the settlement. The consent order also indicates that Prism denied and continued to deny the facts of the case, as well as the violations alleged in the administrative order, maintaining that it was not liable for civil penalties. “It is agreeing to the obligations imposed…solely to settle the disputed claims without incurring the time and expense of additional litigation,” according to the agreement. Health officials said asbestos-related enforcement actions are on the rise. Why does that matter? Because asbestos refers to a group of naturally occurring, fibrous minerals that can cause severe breathing issues and even cancer. During demolition and some building renovations projects, old, brittle asbestos products can release tiny – even microscopic – fibers. These colorless, odorless fibers can remain suspended in the air, entering the lungs when you inhale. Editor’s Note: You can read the entire settlement agreement here. The administrative order filed against Prism was one of several related to the response to and cleanup following the Sheraton Hotel fire.

The U.S. Environmental Protection Agency on Friday announced a settlement with MarkWest Liberty Bluestone, L.L.C. to settle alleged Clean Air Act violations at its natural gas processing plant in Evans City. EPA cited MarkWest for violations that included: Failure to timely conduct a third-party leak detection and repair audit, Failure to timely comply with requirements for monitoring leaks at connectors, and Failure to timely apply to incorporate these leak detection requirements into a federally enforceable state operating permit. These alleged violations increased the risk of excess fugitive volatile organic compound emissions from the facility. Also known as VOCs, volatile organic compounds can cause both short-term and long-term health effects, including everything from headaches and irritation of the respiratory tract to organ damage and even cancer. EPA identified the alleged violations while reviewing the company’s compliance with a previous administrative compliance order from March 2017 related to prior violations. As part of the settlement, MarkWest did not admit liability for the alleged violations but has agreed to pay a penalty of $150,000 and has certified that it is now in compliance with applicable Clean Air Act requirements. #volatileorganiccompounds #MarkWest #fugitiveemissions #leakdetectionsystem #VOCs #CleanAirAct

UPDATE: BRP4 LLC and Level Line Building Co. on Oct. 20 appealed the enforcement order issued by the Allegheny County Health Department. You can read the appeal here. The Allegheny County Health Department (ACHD) on Sept. 25 assessed a more than $31,000 civil penalty against two companies it says violated local Air Pollution Control Act regulations relating to asbestos abatement at a commercial structure in Wilkins Township. According to an associated enforcement order, BRP4 LLC of Wexford (the company that owns the property) and Pittsburgh-based Level Line Building Co. (the company responsible for the demolition of the property) demolished the structure without first submitting required asbestos abatement documentation for the 2019 project. ACHD said the companies failed to test the roof for asbestos. In areas where no samples were taken, ACHD deems it to be what it refers to as asbestos-containing material (ACM). “When removing the roof for demolition, Level Line did not follow standard work procedures while removing (asbestos-containing material) due to asbestos waste not being properly bagged and transported to an approved landfill,” ACHD indicated in the order. Of the $31,500 civil penalty assessed, $9,000 was for reckless conduct. “The gravity-based component of the civil penalty reflects the severity of the violation and the potential harm to the public or environment from the violation,” according to the order. BRP4 and Level Line have 30 days to either pay the fine or appeal the enforcement order. The enforcement order is one of many issued recently from the health department, which has reported an uptick in asbestos-related infractions. For those who might be unfamiliar: asbestos refers to a group of naturally occurring, fibrous minerals that can cause severe breathing issues and even cancer. During building renovations projects, old, brittle asbestos products can release tiny – even microscopic – fibers.

To the folks she’s led on hikes and other activities, she’s a wealth of knowledge about air quality and how it impacts the natural world around us. To the children she’s taught about air pollution through hands-on workshops,  she is affectionately known as The Pig Lung Lady. But to GASP, Chelsea Hilty is an all-star educator – and a teammate we are going to miss terribly. After nearly four years at the helm of our education and events planning, Chelsea is (sadly) leaving GASP following an out-of-state move. While we wish her the best, we couldn’t let her go before we let her know just how much of an impact she helped make during her tenure here. Because although GASP has long engaged in educational efforts, Chelsea came on board when GASP was awarded an EPA grant to create an air quality educational summer camp for kids – and she jumped right in to create a curriculum and a plan to reach as many classrooms as possible. “She came on board when youth education was really taking off at GASP,” GASP Executive Director Rachel Filippini said. And she had to hit the ground running. “She essentially created an entire curriculum for our summer youth education program,” she added.  “It was all in Chelsea’s lap.” It was clear from the very beginning that she was at home in front of a roomful of kiddos. “She just has a very good rapport with youth. She doesn’t talk down to them. She treats kids with the respect they deserve,” Filippini said. “Kids can tell when someone is being sincere and when they’re being fake.” It’s not just youth education that Chelsea spearheaded during her tenure at GASP: She also taught OSHER courses – where she educated retirees about issues related to air pollution and public health at Pitt and CMU. But education is just half of what Chelsea did here at GASP: She was also our events coordinator and spent the better part of a year planning and prepping for our 50th-anniversary gala. While the event was a team effort, Chelsea was the one taking the lead- identifying potential sponsors, researching locations and menus, brainstorming decor ideas, and even creating a year’s worth of weekly tips for folks to follow to be greener as a leadup to the event. She was also chiefly responsible for sifting through boxes (and boxes – so many boxes) of GASP’s archived material to showcase the very best watchdog, educational, and advocacy work from our 50-year history. Patty Himes, a naturalist educator at Frick Environmental Center who was honored with a Michelle Maddoff Award of Environmental Excellence at our 50th, met Chelsea when she worked at the organization as an intern. “Her time here was a tremendous gift, “ she said. “Chelsea is a talented and thoughtful educator. She is down-to-earth and practical. I have always thought of her as a ‘go to’ colleague,” Himes added.”She was someone I could ‘go-to’ and work through work-related challenges. She was someone I could count on to do a thorough and quality job. She was someone that was committed and I could trust.” GASP Board President Jonathan Nadle agreed. “Her passion for education and community engagement was evident and she developed several well-regarded, innovative and successful education programs,” he said. Filippini agreed. “While we are sad to see Chelsea go she leaves the organization in a stronger, more effective place when it comes to environmental education. Thank you, Chelsea, for everything you’ve done for us over the last couple of years,” she said. Editor’s Note: Feel free to leave a little love for Chelsea in the comments section below! We’ll make sure she sees ’em.

The U.S. Attorney’s Office for the Middle District of Pennsylvania announced recently that two companies have entered a plea agreement that calls for a combined $4.3 million in penalties for their involvement in Clean Air Act violations. One of those firms is local: Rockwater Northeast is headquartered in Washington County. The Marcellus Shale water hauling firm agreed to plead guilty to tampering with emissions-control devices on 31 of its heavy-duty diesel vehicles and pay a $2 million fine. According to court documents, Rockwater employees disabled emissions-control devices on 31 of its diesel trucks using aftermarket devices between Aug. 1, 2013, and June 30, 2014. And that’s not all. “Rockwater Northeast also is alleged to have caused the trucks to pass annual vehicle safety inspections by the Department of Transportation (DOT), despite the modified emissions systems,” prosecutors said in a press release. Separately, Select Energy Services, Inc., a Texas-based company and the successor to Rockwater Energy Solutions, Inc., entered a three-year non-prosecution agreement resolving Clean Air Act violations for modified emissions systems on 29 additional heavy-duty diesel trucks that were owned by Rockwater Energy Solutions. The company will pay a $2.3 million fine. Vehicle owners sometimes tamper with or disable emissions-control devices because they believe they cause their vehicle to lose horsepower and/or reduce the vehicle’s gas mileage. Whatever the reason it’s a bad idea. Tampering with a vehicle emissions control system is illegal and can negatively affect vehicle performance, void warranties, and contribute to air pollution. Six individuals were also prosecuted in connection with this investigation – four of whom are current or former employees of Rockwater Northeast, and two of whom are former third-party vendors of the company. “The defendants in this case knowingly and repeatedly installed ‘defeat devices’ to remove emissions controls in dozens of diesel trucks in violation of the Clean Air Act,” said Environmental Protection Agency (EPA) Special Agent in Charge Jennifer Lynn of EPA’s Criminal Investigation Division in Pennsylvania." The damage done? Tons of excess nitrous oxide and particulate matter were released into the air from those trucks during that time period. For those who might be unfamiliar: Breathing in nitrous oxide can cause a host of health impacts such as dizziness, unconsciousness, and even death. Long-term exposure can lead to infertility. Particulate matter is associated with respiratory and cardiovascular problems, cancer and even death. You can read more about what was alleged in U.S. District Court here.

Originally created as a way to draw attention to its efforts to improve awareness of air quality issues, GASP’s Dirty Gertie the Poor Polluted Birdie is back to educate (and dare we say entertain?) a new generation of difference-makers. PITTSBURGH – This fall, designers are throwing it all the way back to the ‘70s, with fashion lines featuring bell-bottoms, platform shoes, overalls, and other trends made famous during the Me Decade. GASP decided it would do the same. Because everything old is new again, the nonprofit decided to bring back one of its favorite relics from the age of disco: Our fine-feathered mascot, Dirty Gertie the Poor Polluted Birdie. With the help of a trio of local artists, Dirty Gertie will fly again on Oct. 18 as the host of GASP’s first-ever trivia night. While our gal Gertie first appeared as a cartoon in our outreach videos way back when, the character morphed into GASP’s official mascot years later, when one of our members would don a bird costume to raise awareness of Pittsburgh’s air pollution problem. Seriously. The 197os-era mascot costume was terrifying. “No lie: We’ve been told that the Dirty Gertie Costume from the ‘70s was – and I’m quoting directly – ‘the stuff of nightmares,’” GASP Executive Director Rachel Filippini said. “We’re thankful to our new friends in the art and comedy communities for helping to bring to life a far less terrifying iteration of a Pittsburgh classic. Dave English was really the driving force behind the new-and-improved Gertie.” English, a ‘Burgh-born comedian/artist/puppeteer, and host of Pittsburgh Puppet Radio said he was inspired to get more involved with GASP after Filippini appeared on his show earlier this year to talk about Allegheny County’s poor air quality. “It was last Christmas when we had the toxic smog gagging us that I decided I might look into getting involved. By that I mean I got pretty pissed off that I couldn’t breathe and decided to do a live puppet show about air quality,” he said. “It was The Pittsburgh Puppet Radio Show and Rachel was one of my guests. She downplays it but she was the star of the show delivering some sobering news to my audience of adult puppet enthusiasts. In that interview, we looked back at Gertie’s era and existence and planted the seeds of her resurrection.” In the months since English has connected GASP with two of his friends and colleagues to lend their skills to make that resurrection happen. One of them is Pittsburgh-based mixed-media artist Leah Pecoraro-Eddy, who created the 2020 version of Dirty Gertie the Poor Polluted Birdie, crafting her into a bright red hand puppet. She said the decision to get involved in the endeavor was a no-brainer. “I met Rachel Filippini during Dave English’s puppet radio show in February at the Glitterbox Theater. I believe Dave and I actually spoke that night about working on something for GASP. It was almost an immediate response both Dave and I had, we just knew we wanted to get involved,” she said. “I am always interested in working with environmental groups as a way to benefit extremely useful efforts while doing something I’m good at: Making art.” Over the past few months, Eddy has worked to give Dirty Gertie the Poor Polluted Birdie a glow-up. The first iteration of our girl Dirty Gertie the Poor Polluted Birdie was a cartoon. “I looked at all the old animations and pulled up stills. From there, I figured out the scale I wanted and created patterns to get as close to the original as possible,” she said, adding it took about five days to create. “I had a lot of fun building this puppet, as well as her little set and podium. The set was sort of inspired by those great old ‘70s game show sets.” While Eddy was the mastermind behind the puppet, Pittsburgh actress and artist Tenley Scmida was tapped to play the Dirty Gertie character – a role she jumped at to play. “I’ve known Dave from the Glitterbox Theater scene. We’ve done some stuff together and he knows I’m rather good at characters, voices, and improv so he asked me if I would put all three together and host this trivia night AS A BIRD CHARACTER…which is the sort of challenge I can really get behind,” she said. Schmida said she can’t wait to see the reaction to her version of Dirty Gertie, and admits she’s still working out exactly what the poor polluted birdie’s voice will sound like just yet. “I babble to my dog every morning while I make his breakfast and my coffee, always trying out new combos. I’m torn between ‘Foxy Ingenue Judy Garland,’ ‘Mid-Atlantic Exercise Guru,’ or a wildcard I’ll simply refer to as ‘Flirty Fargo,’” she said. “It will all come together once I get my hand inside that puppet. I cannot know it’s mind until we are joined as one.” Those who want to get a first look at Gertie are cordially invited to attend GASP’s first-ever trivia night – an online event that will serve as one of the nonprofit’s fundraising events. All proceeds will go toward the fight for clean air in southwestern Pennsylvania. “It’s going to be the most fun you’ve ever had talking about air pollution. It will be a mix of trivia from the host puppet, cut-aways to music and other puppets, maybe some special appearances, and important messages from GASP staff,” English said. “Activism is happening in many directions for many reasons but there are places where it all intersects. I think breathing is one of those intersections. If you like breathing, puppets, and want to help make a difference this is the show for you.” Filippini agreed, adding that GASP intends to utilize the new Dirty Gertie puppet to help amplify its educational efforts at local schools and events. “Air quality is an inherently complex and somewhat dry topic,” she said. “We hope the new-and-improved Dirty Gertie will allow us to help us educate folks about issues related to air pollution and its impacts in a way that’s a bit more palatable than something like a Powerpoint presentation.” GASP’s trivia event featuring Dirty Gertie will kick off at 7 p.m. Oct. 18. You can register for the fundraising event online. Group Against Smog and Pollution (GASP) is a 501 (c)(3) non-profit citizens’ group in Southwestern Pennsylvania working for a healthy, sustainable environment. Founded in 1969, GASP has been a diligent watchdog, educator, litigator, and policy-maker on many environmental issues, with a focus on air quality in the Pittsburgh region. ### FOR IMMEDIATE RELEASE Media Contact: amanda@gasp-pgh.org #DirtyGertiethePoorPollutedBirdie

“School buses travel over four billion miles each year, providing the safest transportation to and from school for more than 25 million American children every day,” the EPA website explains. “However, diesel exhaust from these buses has a negative impact on human health, especially for children, who have a faster breathing rate than adults and whose lungs are not yet fully developed.” The office is now accepting applications nationwide for rebates to assist in replacing older, dirtier diesel school buses with new school buses certified to EPA’s cleanest emission standards. EPA anticipates awarding more than $10 million through the Diesel Emissions Reduction Act (DERA) program. Selected applicants that scrap and replace their old diesel buses will receive a rebate of $20,000-$65,000 per bus depending on the fuel type of the replacement bus. Here’s what you need to know if you want to apply: Regional, state or tribal agencies including school districts and municipalities are eligible Also eligible are private entities that operate school buses under a contract with school districts and municipalities Applications are limited to 10 buses. Fleets that own more than 100 buses can submit two applications. Rebate recipients will be selected via lottery, with at least one selected from each state/territory represented in the applicant pool. “While we know that particulate pollution from dirty diesel poses one of the greatest cancer risks of any toxic outdoor air pollutant, replacing school bus fleets is an expensive endeavor,” GASP Executive Director Rachel Filippin said. “GASP hopes local school districts and bus companies take advantage of this opportunity to help them make their transportation operations cleaner and healthier for the precious cargo they transport each day.” #DieselEmissionsReductionsAct #schoolbusretrofit #diesel #emissions #EPA #dieselemissions

Allegheny County Controller Chelsa Wagner on Tuesday said her office’s audit of the County Health Department’s (ACHD) Clean Air Act permitting program showed improvements in 2019 over its previous audit five years before but added that it continued to fall short of full compliance with its obligations under federal law. Title V Section 503(c) of the Clean Air Act indicates that permitting authorities such as ACHD “shall approve or disapprove a completed [Title V operating permit] application, and shall issue or deny the permit, within 18 months after the date of receipt thereof.” The issuance of Title V operating permits to major pollution sources is what triggers the requirement for these sources to certify at least annually that they are Title V compliant. When Title V permits are outstanding, major sources can avoid providing these certifications. The issuance of Title V operating permits, which typically include the compliance requirements contained in any installation and other permits issued, also facilitates compliance monitoring and enforcement. “Both the manufacturing companies that apply for these permits and the general public deserve to have clear expectations and information on what these facilities are allowed to emit, which requires permit issuance in a timely fashion in compliance with the federal Clean Air Act,” Wagner said in a press release. “I’m encouraged by the progress made by the Health Department in this regard, and by their openness and cooperation in this audit.” As of Dec. 31, 2019, ACHD had not issued or denied Title V operating permits for seven of the 31 major sources in Allegheny County within 18 months from the date that complete permit applications were received. GASP has been tracking a backlog for new and renewed operating permits for major sources of air pollution in both Allegheny County and the Pennsylvania Department of Environmental Protection’s (DEP) Southwest Regional Office since 2016 and is heartened by the audit findings. “We hope the downward trend in outstanding permits continues, and that DEP works just as diligently to get its own backlog down,” GASP Executive Director Rachel Filippini said. “Air quality remains a serious public health issue in the Keystone State generally and Allegheny County in particular – regulators must remain vigilant.” A major source is generally a stationary source of air pollutants that emits or has the potential to emit 100 tons per year of any air pollutant, 50 tons per year of volatile organic compounds, 10 tons per year of any hazardous air pollutant, or 25 tons per year of a combination of hazardous air pollutants. Three outstanding applications were initial permit applications while the other four applications were renewal applications. ACHD developed a formal corrective action plan to eliminate the permitting backlog at the request of the U.S. Environmental Protection Agency (EPA) in June of 2018. The corrective action plan submitted by the ACHD sought the elimination of the backlog within three years. ACHD’s communications with auditors indicated significant progress toward this goal, Wagner said. “I am pleased that my office’s previous audits were able to help the ACHD and the public identify the permitting backlog as an issue of concern, and lead to the concerted effort and measurable progress we have seen to rectify it,” Wagner said. The audit noted that circumstances beyond the ACHD’s control involving further federal compliance issues have impacted its ability to issue Title V operating permits to three of the major sources. In addition, public comment on one outstanding draft permit ended Aug. 17, 2020, and ACHD management indicated that the final permit may be issued shortly. Another draft permit has been reviewed by the ACHD and is currently in a pre-public-comment review by the company. A further draft permit has been completed and is currently being reviewed internally by the ACHD. ACHD management advised auditors that draft permits for the other major sources that compose the Title V operating permit backlog are also in various stages of completion. The previous audit cited understaffing in the permitting program as a primary reason for the backlog, which led the ACHD to engage an outside consultant to recommend an adequate staffing level. However, the ACHD was still short of the recommended staffing level by two full-time equivalent (FTE) positions at the end of 2019. The ACHD created two new full-time Engineer Trainee positions in 2018. These positions had not been filled during the period of the audit, but ACHD management informed auditors they were filled in early 2020. One of the ACHD’s Permitting Engineers also left the ACHD’s employ during 2018, which resulted in the ACHD being three full-time equivalents (FTEs) short of the recommended staffing level at the beginning of 2019. ACHD did add two part-time contractors as Permitting Engineers during 2019, one in March and one in November. The ACHD lost one Permitting Engineer in March of 2020 who transitioned to a position in another area of the ACHD’s Air Quality Program, leaving the ACHD still one FTE short of the recommended Permitting Engineer staffing level, but ACHD management has indicated that it is attempting to fill the position. “The professional resources we choose to dedicate to a given government function are always an indication of the importance we place on it, and I am encouraged that ACHD looks to have made progress on correcting the understaffing issues identified in our previous audit,” Wagner said. The Controller’s office also examined the books of the Title V Air Quality Fund, which collects all emission fees, related interest, and other fees required by Title V of the Clean Air Act. The fees and related interest collected can only be used to fund the costs of developing and administering a pollution control program in accordance with Title V of the Clean Air Act. The Fund collected approximately $1.5 million in 2019, primarily from four sources: U.S. Steel Clairton Works ($641,838), U.S. Steel Irvin Plant ($350,701), Genon Midwest LP Cheswick ($189,924), and U.S. Steel Edgar Thomson Works ($169,943). “The receipts to this fund illustrate the significant emissions from some of the major industrial facilities in the County, and that these are concentrated in some of our most economically disadvantaged communities. We know that high levels of emissions have real health effects on our population, especially our most vulnerable children and seniors,” Wagner said. “We must continue to be forward-thinking in our efforts to reduce harmful environmental conditions even as we support and maintain the quality jobs these facilities provide. This is not a zero-sum game.” Editor’s Note: View the Independent Auditor’s Report Allegheny County Health Department Title V Air Quality Fund for the Year Ended December 31, 2019. #permitbacklog #airpollution #AlleghenyCounty #TitleVpermitbacklog #AlleghenyCountyHealthDepartment #ACHD #airquality
