Trump appointees barred EPA staff from warning Senate about 'forever chemical' loophole: Internal staff messages

News Feed
Tuesday, April 9, 2024

Trump administration officials barred experts from warning legislators that they were about to write a major environmental loophole into law, Environmental Protection Agency (EPA) staffers alleged in newly revealed internal communications.   The loophole, arising from a clause in the 2020 National Defense Authorization Act (NDAA), enabled many companies to avoid disclosing releases of toxic “forever chemicals” to the EPA.  Internal EPA correspondence obtained by The Hill shows that career staff members attempted to make Congress aware of the issue, but they believe their efforts were rebuffed by political appointees.  One employee lamented that career staff “had tried to tell” the Senate about the problem, but he could not get approval to do so.    The clause at issue, written by the Senate Environment and Public Works Committee (SEPW), said on Jan. 1, 2020, some of the chemicals — also known as PFAS — must be included in the EPA’s reporting database for toxic chemical releases: the Toxics Release Inventory (TRI).    But while the clause specified an annual reporting threshold for the compounds, it did not indicate whether Congress intended to deem them “chemicals of special concern,” as opposed to the baseline “standard chemical” label.    Without the stricter designation, polluters could hide their discharges under an exemption intended for chemicals released in small proportions, called “de minimis” concentrations.  Some EPA experts wanted to point this out to Senate staffers but said they were blocked from doing so.   In August 2019, EPA career official David Turk wrote that his team "noticed some nuances that we had not considered previously that might be worth raising to [Senate] staff."  Turk, head of the data-gathering and analysis division within the EPA’s Office of Pollution Prevention and Toxics (OPPT), expressed concern that under the NDAA as drafted, companies would be able to get out of reporting their PFAS discharges if they only made up a small percentage of the total discharge.   "Note that in contacting SEPW staff, we do not plan to take a position on this issue, but rather would like to convey a consideration that we had failed to raise previously," Turk wrote.  His colleague Daniel Bushman, who at the time served as TRI petitions coordinator and chemical list manager, added that "the fix could be as simple as the bill just saying to add PFAS to the list of chemicals of special concern with a 100 pound reporting threshold."  Known for their persistence in the body and the environment, PFAS, or per- and polyfluoroalkyl substances, have been linked to cancers and other serious illnesses. They are present in household items such as nonstick pans, cosmetics and waterproof apparel, and in certain types of firefighting foam.  With no direction otherwise from the NDAA, the EPA’s toxics branch codified 172 types of PFAS as standard chemicals and thereby opened the reporting loophole — publishing an initial version of the rule in May 2020 and finalizing it a month later.   Under this classification, if levels of PFOA, a particularly toxic type of PFAS, constituted less than 0.1 percent of a given mixture, or if those of the other 171 kinds of the toxic compounds were below 1 percent, sites would be exempt from disclosing their discharge. Given that even unsafe levels of PFAS generally occur in comparatively tiny quantities, the classification meant that hardly any facilities would need to file a report.   Bureaucratic breakdown  EPA experts from the Toxics Release Inventory Program had recognized the problem nearly a year before — but found themselves talking to a brick wall built by the Trump administration, according to the internal correspondence.   The experts recalled trying to inform the Senate committee that the language they were incorporating would not likely lead to stricter PFAS release reporting.   But these messages apparently never reached their intended recipients.  “Starting in late July 2019 we became aware of this issue and tried to raise it with Michal on multiple occasions,” Turk wrote in a June 10, 2020, email chain.  Turk was referring to Michal Freedhoff, who at the time served as minority director of oversight — a Democratic staffer — for the Senate committee.   That same day in 2020, Turk made similar remarks to another colleague, Stephanie Griffin, noting that "SEPW staff is pissed that we didn’t tell them about the whole chemicals of special concern issue.”   "We had tried to tell them,” he continued. "It’s all very awkward.”  Asked by Griffin where the breakdown in communication occurred, Turk said that it was “initially, Mark Hartman. And then Nancy Beck.”   Mark Hartman, the OPPT’s deputy director of programs, is a career official. Nancy Beck was a Trump appointee who served as deputy and then principal deputy assistant administrator of the EPA’s Office of Chemical Safety and Pollution Prevention (OCSPP), which houses the OPPT. Prior to taking on the EPA role, Beck worked for five years as an executive at the American Chemistry Council, a chemical industry lobbying group.      In his exchange with Griffin, Turk then recounted a situation in which he and his colleagues were blocked from sharing the issue with the Senate committee.  “Then we finally did get approval to include it in materials to send to Nancy that she might then send to SEPW, which we knew she wouldn’t send to them,” Turk added.  The “awkwardness” Turk referred to stemmed from an email sent earlier that day from Freedhoff to Sven-Erik Kaiser of the EPA’s Office of Congressional and Intergovernmental Relations, expressing shock that the May prepublication labeled PFAS as standard chemicals. The designation, she noted, could make PFAS “eligible for the de minimis concentration exemption.”  “To get around TRI reporting for a listed PFAS chemical, all one would need to do is dilute the 100 lbs in 10,000 lbs of something else,” Freedhoff wrote. “This is not what Congress intended — we intended for reporting to occur for all releases that exceeded 100 lbs.”  She stressed that the purpose of the NDAA clause “was certainly NOT to allow an entity to avoid reporting in the first place.”    A significant portion of the June 11 communications among Turk and his colleagues were redacted under Freedom of Information Act procedures. But one visible portion affirmed Freedhoff’s assertions that EPA staffers never warned her that the NDAA language could prevent PFAS from being listed as chemicals of special concern.   “We did not have direct interactions with Michal and did not control the delivery of information to Michal,” Turk added. “It appears that our messages on the topic never did reach her.”   Slipping through the cracks  Correspondence from 2019 shows that career EPA staffers made multiple attempts to warn Freedhoff about the loophole.  Kaiser, a career official at the agency, initially expressed confidence to her that the clause would do what lawmakers wanted. In a June 17, 2019, email to Kaiser about the clause in question, Freedhoff asked whether "this does what it needs to do." Kaiser responded that the EPA believed the "language achieves the drafters' intent."   But less than a month later — on July 10, 2019 — Bushman, the TRI petition coordinator, noted that the draft "does not classify PFAS as chemicals of special concern.”   Bushman expressed concern that facilities would be able to claim that they stayed below the annual reporting thresholds, which he said “defeats the idea of having 100 lb reporting threshold to capture small quantities."   Turk echoed Bushman's comments, also noting on July 10, 2019, that the reporting loophole "would put a [serious] damper on the utility of the TRI data."  A few weeks later, on Aug. 6, Turk wrote to several staff members and Hartman, the OPPT’s deputy director of programs, warning that under the NDAA draft as written, companies would be able to “use the de minimis exemption, which could result in the loss of reporting."   Turk expressed similar unease on Sept. 12, 2019, alerting Kaiser that the TRI/OPPT team had generated technical assistance "when Nancy reached out for info," but that "it was unclear" whether the EPA was "also providing that document to SEPW staff."   Turk asked Kaiser if it "would be inappropriate to share” the special concern details with Freedhoff. Kaiser said he would "see if there's an opportunity,” but that he thought they had previously raised the matter and that Senate staff “weren't in position to address it at the time."  Turk emphasized that he had only recognized this "nuance" recently — meaning that if his message was not conveyed alongside the technical data Beck had requested, then EPA staff would have "never raised it" to SEPW, as they "wouldn't have known to do so."  A week later, on Sept. 19, Turk once again informed his colleagues that he was uncertain as to whether the EPA team ever delivered the message to SEPW.   "I believe it went to Nancy Beck, but I don't know if it went to SEPW," Turk said.   To this, longtime career staffer Tala Henry, then deputy director of OPPT, responded, "I don't think we can raise other issues," adding that this "specific request is late in the game."  Asked by email why she might have deemed the request "too late in the game," Henry, who no longer works at the EPA, stressed that she had not reviewed the correspondence, which was available due to a Freedom of Information Act request.   But based on her memory of the internal EPA exchanges, she said she recalled that "the TRI team had already provided the technical assistance requested by SEPW."   This process, Henry continued, occurred "with all requisite clearance by EPA Office of General Counsel and political leadership and coordination clearance through EPAs Office of Congressional Affairs."  "The legislation (part of the NDAA) was imminent," she added.  An outcome ‘of maximum awkwardness’  Nine months after the September 2019 internal EPA communications, in June 2020, it became clear Freedhoff and her SEPW team had never received the information about the loophole that agency staffers had tried to convey.   On June 9, Turk reported in an email to his colleagues that he had done "a little researching of [his] inbox" and indicated his concern that the career staffers' message had not been relayed to the committee, despite Kaiser recalling in a past exchange with Turk that it had been.  “I don’t believe that we had yet presented this topic to him as something to share with SEPW, for at the OPPT or OCSPP level it kept getting stripped,” Turk wrote.   By this time, the EPA had issued its rule codifying PFAS as a standard chemical.   In Freedhoff’s June 10 email expressing shock about the classification, originally sent to Kaiser, she asked whether the EPA could withdraw the rule prior to its official publication and launch a notice and comment process to allow her colleagues “to describe their intent in writing.”  As the email spread among EPA staffers that day, Turk told Griffin, an OPPT team lead, that Freedhoff had asked “to pull the final rule because it doesn’t reflect their intent.”   Reiterating how he and his team had anticipated this outcome the summer before, Turk stressed that they “had discussed that SEPW would be upset when they learned that we didn’t tell them of this issue, which was one of the reasons we had tried to tell them of it.”  At around the same time, Turk told Bushman, the TRI petition coordinator, that he was “not looking forward to the ‘discussion’ with Michal.”   “It’s not like we can be open/honest with her given that we had wanted to convey all of this to her but we hadn’t been able to do so,” he continued. “‘You got it wrong, we realized that you got it wrong, and we never told you,’ also isn’t a viable discussion.”  “I suppose we can point to Nancy Beck. But, even that, seems fishy,” Turk added.   Bushman agreed, though he said he was reluctant “to take the heat for management’s unwillingness to let them know that what they were writing was not going to get them what they wanted.”   But he surmised that nothing could be done about the situation at the time, adding that “if the Admin changes then next year we could likely address it.”  Asked about the accusations lodged against her by the EPA staffers, Beck, who is today director of regulatory science at the law firm Hunton Andrews Kurth LLP, said that she did not have time to delve into all the correspondence.   Beck noted, however, that in January 2019, Alexandra Dunn became the Senate-confirmed assistant administrator of the OCSPP — the position directly above her.   “She was the decision maker, not me,” Beck wrote in an email, adding that she “went on a detail” to the National Economic Council in June 2019. “Perhaps Alex has a recollection of this issue and can discuss it with you.”  The Hill has reached out to Dunn, who is now the president and CEO of agrochemicals group CropLife America, for comment.  As Turk and Bushman wrote back and forth on that June 10, 2020, evening, the former suggested how interesting it would be “if the admin changes and Michal joins the EPA,” predicting “the most ridiculous outcome in terms of maximum awkwardness.”  Whether Turk was joking or serious, this is at least in part what happened. Freedhoff assumed Beck’s former role in January 2021 and received Senate confirmation to lead the OCSPP later that year.    A reversal — and a ‘re-reversal’  Two days after Turk and Bushman’s June 10 banter, it became clear in the email correspondence that the TRI Program Division was preparing for a potential about-face — to possibly list the 172 PFAS as chemicals of special concern.    “At this point, it appears that the NDAA listing rule will now indicate that the NDAA-added PFAS will be listed as ‘chemicals of special concern,’” Turk wrote to colleagues on the morning of Friday, June 12, warning that they “are not notifying anyone of this change.”   But just three days later, on Monday, Turk said he was “not sure what’s happening,” adding that his team was “in a momentary holding pattern.” And by Wednesday, Turk wrote that “the rule is going out as originally intended, in alignment with the prepublication version.”   Responding to what Turk described as a “re-reversal,” Bushman voiced suspicions that this was "due to conversation with the administrator and possibly some feedback from industry if someone reached out.”   The team reverted back to the prepublication version of the rule, finalizing the text on June 22, 2020, and leaving the 172 PFAS, for the time being, in the standard chemical category.   In the hands of ‘political leadership’   Freedhoff, Turk and Bushman ended up being correct in their projections that the June 2020 standard chemical listing would lead to minimal PFAS reporting.    In the aftermath of the rule’s implementation, the EPA revealed that during the first year of reporting — for 2020 — the nation’s facilities managed 800,000 pounds of PFAS in 2020 but only disclosed 9,000 pounds as releases.  Following the transition from a Trump to Biden administration and with Freedhoff at the helm, the OCSPP and OPPT did ultimately decide to categorize 189 types of PFAS as chemicals of special concern more than two years after the loophole was opened.   The agency proposed the new rule in December 2022 and finalized it in October 2023 — scrapping the de minimis exemption and making it much harder to avoid reporting releases.   While the stricter designation will apply to submissions in reporting year 2024, industry can follow the standard chemical rules for their 2023 filings, which are due by July 1, 2024, according to the EPA.  Environmental advocates worry the shift will be too little, too late.    Nathan Saunders, a Maine environmental health official who first urged The Hill to look into the correspondence, stressed just how damaging the postponement could be for communities affected by PFAS.  “The whole U.S. population was delayed from knowing PFAS release for four years,” said Saunders, who manages the Radiation Control Program in Maine’s Center for Disease Control and Prevention and delved into the issue after massive amounts of PFAS were detected on his property.   Saunders blamed the setback on what he described as a “conscious identification of PFAS chemicals as standard chemicals.”   That conscious decision, he added, occurred “at the expense of public health and to the benefit of the corporate profits."  Responding to a long list of questions about the internal haggling that informed TRI-related decisions, EPA press secretary Remmington Belford said in an emailed statement that Freedhoff, in her prior role at the SEPW, had “worked closely with EPA career staff” as her committee drafted the clause that would add the 100-pound reporting threshold.   Noting that the threshold was discussed on multiple occasions, Belford stressed that “at no time before the law was enacted” was Freedhoff told that lowering the threshold would be insufficient to eliminate the de minimis exemption — and would therefore not ensure “that the transparency objectives of the legislation would be met.”  Once she understood the truth, Freedhoff “did attempt to get EPA to change course,” according to Belford. After the law was enacted, she learned from EPA career staff “that political leadership in the previous administration did not allow [them] to present Congress with additional technical assistance” that would have explained the de minimis issue, he added.   Belford did acknowledge, however, that there was some initial confusion among EPA staff members. The confusion arose from the fact that to date, the only TRI chemicals assigned such thresholds were those in the “special concern” umbrella, he noted.    “Certain EPA career staff members wanted to clarify for Senate staff that if their intent was to designate the TRI-added PFAS as ‘chemicals of special concern,’ the text as written would not accomplish this intent,” Beck confirmed.   Asked specifically whether Beck or Hartman — who still works at the EPA — was responsible for blocking the message, Belford responded that “some of the people involved with the technical assistance for the 2020 NDAA are no longer with the agency.”  The understanding of OCSPP career managers, Belford explained, is that “the previous administration’s political appointees opted not to share” information about the exemption with SEPW staff.  “This understanding is consistent with what Dr. Freedhoff was told at the time by EPA career staff — this decision was not made by EPA career staff or managers,” he continued.   “EPA, like all federal agencies, includes both career civil servants hired through a competitive process and political appointees appointed by the President,” Belford said. “Ultimately, EPA career staff members (including senior career managers) are led by political appointees and are obligated to follow the direction they are provided.”  Asked if industry interests influenced the chemicals’ standard designation, as Bushman suggested in internal correspondence, Belford said that “industry did not contact career staff working in EPA’s TRI program to lobby, pressure or express their preferences regarding the text of the 2020 NDAA or its implementation.”   “EPA is not aware of whether industry contacted the political leadership of the agency that was in place at that time,” he added, reiterating that “EPA career staff are required to follow the direction of the political leadership.”  Once President Biden took office, Belford said “it was an immediate priority” for both the administration and EPA career staff to designate the TRI-listed PFAS as chemicals of special concern — a decision he in part attributed to Freedhoff, who joined the OCSPP in January 2021.  “In Dr. Freedhoff’s view, this was always the intent of Congress in passing the NDAA,” Belford added.

Trump administration officials barred experts from warning legislators that they were about to write a major environmental loophole into law, Environmental Protection Agency (EPA) staffers alleged in newly revealed internal communications.  

The loophole, arising from a clause in the 2020 National Defense Authorization Act (NDAA), enabled many companies to avoid disclosing releases of toxic “forever chemicals” to the EPA. 

Internal EPA correspondence obtained by The Hill shows that career staff members attempted to make Congress aware of the issue, but they believe their efforts were rebuffed by political appointees. 

One employee lamented that career staff “had tried to tell” the Senate about the problem, but he could not get approval to do so.   

The clause at issue, written by the Senate Environment and Public Works Committee (SEPW), said on Jan. 1, 2020, some of the chemicals — also known as PFAS — must be included in the EPA’s reporting database for toxic chemical releases: the Toxics Release Inventory (TRI).   

But while the clause specified an annual reporting threshold for the compounds, it did not indicate whether Congress intended to deem them “chemicals of special concern,” as opposed to the baseline “standard chemical” label.   

Without the stricter designation, polluters could hide their discharges under an exemption intended for chemicals released in small proportions, called “de minimis” concentrations. 

Some EPA experts wanted to point this out to Senate staffers but said they were blocked from doing so.  

In August 2019, EPA career official David Turk wrote that his team "noticed some nuances that we had not considered previously that might be worth raising to [Senate] staff." 

Turk, head of the data-gathering and analysis division within the EPA’s Office of Pollution Prevention and Toxics (OPPT), expressed concern that under the NDAA as drafted, companies would be able to get out of reporting their PFAS discharges if they only made up a small percentage of the total discharge.  

"Note that in contacting SEPW staff, we do not plan to take a position on this issue, but rather would like to convey a consideration that we had failed to raise previously," Turk wrote. 

His colleague Daniel Bushman, who at the time served as TRI petitions coordinator and chemical list manager, added that "the fix could be as simple as the bill just saying to add PFAS to the list of chemicals of special concern with a 100 pound reporting threshold." 

Known for their persistence in the body and the environment, PFAS, or per- and polyfluoroalkyl substances, have been linked to cancers and other serious illnesses. They are present in household items such as nonstick pans, cosmetics and waterproof apparel, and in certain types of firefighting foam. 

With no direction otherwise from the NDAA, the EPA’s toxics branch codified 172 types of PFAS as standard chemicals and thereby opened the reporting loophole — publishing an initial version of the rule in May 2020 and finalizing it a month later.  

Under this classification, if levels of PFOA, a particularly toxic type of PFAS, constituted less than 0.1 percent of a given mixture, or if those of the other 171 kinds of the toxic compounds were below 1 percent, sites would be exempt from disclosing their discharge. Given that even unsafe levels of PFAS generally occur in comparatively tiny quantities, the classification meant that hardly any facilities would need to file a report.  

Bureaucratic breakdown 

EPA experts from the Toxics Release Inventory Program had recognized the problem nearly a year before — but found themselves talking to a brick wall built by the Trump administration, according to the internal correspondence.  

The experts recalled trying to inform the Senate committee that the language they were incorporating would not likely lead to stricter PFAS release reporting.  

But these messages apparently never reached their intended recipients. 

“Starting in late July 2019 we became aware of this issue and tried to raise it with Michal on multiple occasions,” Turk wrote in a June 10, 2020, email chain. 

Turk was referring to Michal Freedhoff, who at the time served as minority director of oversight — a Democratic staffer — for the Senate committee.  

That same day in 2020, Turk made similar remarks to another colleague, Stephanie Griffin, noting that "SEPW staff is pissed that we didn’t tell them about the whole chemicals of special concern issue.”  

"We had tried to tell them,” he continued. "It’s all very awkward.” 

Asked by Griffin where the breakdown in communication occurred, Turk said that it was “initially, Mark Hartman. And then Nancy Beck.”  

Mark Hartman, the OPPT’s deputy director of programs, is a career official. Nancy Beck was a Trump appointee who served as deputy and then principal deputy assistant administrator of the EPA’s Office of Chemical Safety and Pollution Prevention (OCSPP), which houses the OPPT. Prior to taking on the EPA role, Beck worked for five years as an executive at the American Chemistry Council, a chemical industry lobbying group.     

In his exchange with Griffin, Turk then recounted a situation in which he and his colleagues were blocked from sharing the issue with the Senate committee. 

“Then we finally did get approval to include it in materials to send to Nancy that she might then send to SEPW, which we knew she wouldn’t send to them,” Turk added. 

The “awkwardness” Turk referred to stemmed from an email sent earlier that day from Freedhoff to Sven-Erik Kaiser of the EPA’s Office of Congressional and Intergovernmental Relations, expressing shock that the May prepublication labeled PFAS as standard chemicals. The designation, she noted, could make PFAS “eligible for the de minimis concentration exemption.” 

“To get around TRI reporting for a listed PFAS chemical, all one would need to do is dilute the 100 lbs in 10,000 lbs of something else,” Freedhoff wrote. “This is not what Congress intended — we intended for reporting to occur for all releases that exceeded 100 lbs.” 

She stressed that the purpose of the NDAA clause “was certainly NOT to allow an entity to avoid reporting in the first place.”   

A significant portion of the June 11 communications among Turk and his colleagues were redacted under Freedom of Information Act procedures. But one visible portion affirmed Freedhoff’s assertions that EPA staffers never warned her that the NDAA language could prevent PFAS from being listed as chemicals of special concern.  

“We did not have direct interactions with Michal and did not control the delivery of information to Michal,” Turk added. “It appears that our messages on the topic never did reach her.”  

Slipping through the cracks 

Correspondence from 2019 shows that career EPA staffers made multiple attempts to warn Freedhoff about the loophole. 

Kaiser, a career official at the agency, initially expressed confidence to her that the clause would do what lawmakers wanted. In a June 17, 2019, email to Kaiser about the clause in question, Freedhoff asked whether "this does what it needs to do." Kaiser responded that the EPA believed the "language achieves the drafters' intent."  

But less than a month later — on July 10, 2019 — Bushman, the TRI petition coordinator, noted that the draft "does not classify PFAS as chemicals of special concern.”  

Bushman expressed concern that facilities would be able to claim that they stayed below the annual reporting thresholds, which he said “defeats the idea of having 100 lb reporting threshold to capture small quantities."  

Turk echoed Bushman's comments, also noting on July 10, 2019, that the reporting loophole "would put a [serious] damper on the utility of the TRI data." 

A few weeks later, on Aug. 6, Turk wrote to several staff members and Hartman, the OPPT’s deputy director of programs, warning that under the NDAA draft as written, companies would be able to “use the de minimis exemption, which could result in the loss of reporting."  

Turk expressed similar unease on Sept. 12, 2019, alerting Kaiser that the TRI/OPPT team had generated technical assistance "when Nancy reached out for info," but that "it was unclear" whether the EPA was "also providing that document to SEPW staff."  

Turk asked Kaiser if it "would be inappropriate to share” the special concern details with Freedhoff. Kaiser said he would "see if there's an opportunity,” but that he thought they had previously raised the matter and that Senate staff “weren't in position to address it at the time." 

Turk emphasized that he had only recognized this "nuance" recently — meaning that if his message was not conveyed alongside the technical data Beck had requested, then EPA staff would have "never raised it" to SEPW, as they "wouldn't have known to do so." 

A week later, on Sept. 19, Turk once again informed his colleagues that he was uncertain as to whether the EPA team ever delivered the message to SEPW.  

"I believe it went to Nancy Beck, but I don't know if it went to SEPW," Turk said.  

To this, longtime career staffer Tala Henry, then deputy director of OPPT, responded, "I don't think we can raise other issues," adding that this "specific request is late in the game." 

Asked by email why she might have deemed the request "too late in the game," Henry, who no longer works at the EPA, stressed that she had not reviewed the correspondence, which was available due to a Freedom of Information Act request.  

But based on her memory of the internal EPA exchanges, she said she recalled that "the TRI team had already provided the technical assistance requested by SEPW."  

This process, Henry continued, occurred "with all requisite clearance by EPA Office of General Counsel and political leadership and coordination clearance through EPAs Office of Congressional Affairs." 

"The legislation (part of the NDAA) was imminent," she added. 

An outcome ‘of maximum awkwardness’ 

Nine months after the September 2019 internal EPA communications, in June 2020, it became clear Freedhoff and her SEPW team had never received the information about the loophole that agency staffers had tried to convey.  

On June 9, Turk reported in an email to his colleagues that he had done "a little researching of [his] inbox" and indicated his concern that the career staffers' message had not been relayed to the committee, despite Kaiser recalling in a past exchange with Turk that it had been. 

“I don’t believe that we had yet presented this topic to him as something to share with SEPW, for at the OPPT or OCSPP level it kept getting stripped,” Turk wrote.  

By this time, the EPA had issued its rule codifying PFAS as a standard chemical.  

In Freedhoff’s June 10 email expressing shock about the classification, originally sent to Kaiser, she asked whether the EPA could withdraw the rule prior to its official publication and launch a notice and comment process to allow her colleagues “to describe their intent in writing.” 

As the email spread among EPA staffers that day, Turk told Griffin, an OPPT team lead, that Freedhoff had asked “to pull the final rule because it doesn’t reflect their intent.”  

Reiterating how he and his team had anticipated this outcome the summer before, Turk stressed that they “had discussed that SEPW would be upset when they learned that we didn’t tell them of this issue, which was one of the reasons we had tried to tell them of it.” 

At around the same time, Turk told Bushman, the TRI petition coordinator, that he was “not looking forward to the ‘discussion’ with Michal.”  

“It’s not like we can be open/honest with her given that we had wanted to convey all of this to her but we hadn’t been able to do so,” he continued. “‘You got it wrong, we realized that you got it wrong, and we never told you,’ also isn’t a viable discussion.” 

“I suppose we can point to Nancy Beck. But, even that, seems fishy,” Turk added.  

Bushman agreed, though he said he was reluctant “to take the heat for management’s unwillingness to let them know that what they were writing was not going to get them what they wanted.”  

But he surmised that nothing could be done about the situation at the time, adding that “if the Admin changes then next year we could likely address it.” 

Asked about the accusations lodged against her by the EPA staffers, Beck, who is today director of regulatory science at the law firm Hunton Andrews Kurth LLP, said that she did not have time to delve into all the correspondence.  

Beck noted, however, that in January 2019, Alexandra Dunn became the Senate-confirmed assistant administrator of the OCSPP — the position directly above her.  

“She was the decision maker, not me,” Beck wrote in an email, adding that she “went on a detail” to the National Economic Council in June 2019. “Perhaps Alex has a recollection of this issue and can discuss it with you.” 

The Hill has reached out to Dunn, who is now the president and CEO of agrochemicals group CropLife America, for comment. 

As Turk and Bushman wrote back and forth on that June 10, 2020, evening, the former suggested how interesting it would be “if the admin changes and Michal joins the EPA,” predicting “the most ridiculous outcome in terms of maximum awkwardness.” 

Whether Turk was joking or serious, this is at least in part what happened. Freedhoff assumed Beck’s former role in January 2021 and received Senate confirmation to lead the OCSPP later that year.   

A reversal — and a ‘re-reversal’ 

Two days after Turk and Bushman’s June 10 banter, it became clear in the email correspondence that the TRI Program Division was preparing for a potential about-face — to possibly list the 172 PFAS as chemicals of special concern.   

“At this point, it appears that the NDAA listing rule will now indicate that the NDAA-added PFAS will be listed as ‘chemicals of special concern,’” Turk wrote to colleagues on the morning of Friday, June 12, warning that they “are not notifying anyone of this change.”  

But just three days later, on Monday, Turk said he was “not sure what’s happening,” adding that his team was “in a momentary holding pattern.” And by Wednesday, Turk wrote that “the rule is going out as originally intended, in alignment with the prepublication version.”  

Responding to what Turk described as a “re-reversal,” Bushman voiced suspicions that this was "due to conversation with the administrator and possibly some feedback from industry if someone reached out.”  

The team reverted back to the prepublication version of the rule, finalizing the text on June 22, 2020, and leaving the 172 PFAS, for the time being, in the standard chemical category.  

In the hands of ‘political leadership’  

Freedhoff, Turk and Bushman ended up being correct in their projections that the June 2020 standard chemical listing would lead to minimal PFAS reporting.   

In the aftermath of the rule’s implementation, the EPA revealed that during the first year of reporting — for 2020 — the nation’s facilities managed 800,000 pounds of PFAS in 2020 but only disclosed 9,000 pounds as releases. 

Following the transition from a Trump to Biden administration and with Freedhoff at the helm, the OCSPP and OPPT did ultimately decide to categorize 189 types of PFAS as chemicals of special concern more than two years after the loophole was opened.  

The agency proposed the new rule in December 2022 and finalized it in October 2023 — scrapping the de minimis exemption and making it much harder to avoid reporting releases.  

While the stricter designation will apply to submissions in reporting year 2024, industry can follow the standard chemical rules for their 2023 filings, which are due by July 1, 2024, according to the EPA

Environmental advocates worry the shift will be too little, too late.   

Nathan Saunders, a Maine environmental health official who first urged The Hill to look into the correspondence, stressed just how damaging the postponement could be for communities affected by PFAS. 

“The whole U.S. population was delayed from knowing PFAS release for four years,” said Saunders, who manages the Radiation Control Program in Maine’s Center for Disease Control and Prevention and delved into the issue after massive amounts of PFAS were detected on his property.  

Saunders blamed the setback on what he described as a “conscious identification of PFAS chemicals as standard chemicals.”  

That conscious decision, he added, occurred “at the expense of public health and to the benefit of the corporate profits." 

Responding to a long list of questions about the internal haggling that informed TRI-related decisions, EPA press secretary Remmington Belford said in an emailed statement that Freedhoff, in her prior role at the SEPW, had “worked closely with EPA career staff” as her committee drafted the clause that would add the 100-pound reporting threshold.  

Noting that the threshold was discussed on multiple occasions, Belford stressed that “at no time before the law was enacted” was Freedhoff told that lowering the threshold would be insufficient to eliminate the de minimis exemption — and would therefore not ensure “that the transparency objectives of the legislation would be met.” 

Once she understood the truth, Freedhoff “did attempt to get EPA to change course,” according to Belford. After the law was enacted, she learned from EPA career staff “that political leadership in the previous administration did not allow [them] to present Congress with additional technical assistance” that would have explained the de minimis issue, he added.  

Belford did acknowledge, however, that there was some initial confusion among EPA staff members. The confusion arose from the fact that to date, the only TRI chemicals assigned such thresholds were those in the “special concern” umbrella, he noted.   

“Certain EPA career staff members wanted to clarify for Senate staff that if their intent was to designate the TRI-added PFAS as ‘chemicals of special concern,’ the text as written would not accomplish this intent,” Beck confirmed.  

Asked specifically whether Beck or Hartman — who still works at the EPA — was responsible for blocking the message, Belford responded that “some of the people involved with the technical assistance for the 2020 NDAA are no longer with the agency.” 

The understanding of OCSPP career managers, Belford explained, is that “the previous administration’s political appointees opted not to share” information about the exemption with SEPW staff. 

“This understanding is consistent with what Dr. Freedhoff was told at the time by EPA career staff — this decision was not made by EPA career staff or managers,” he continued.  

“EPA, like all federal agencies, includes both career civil servants hired through a competitive process and political appointees appointed by the President,” Belford said. “Ultimately, EPA career staff members (including senior career managers) are led by political appointees and are obligated to follow the direction they are provided.” 

Asked if industry interests influenced the chemicals’ standard designation, as Bushman suggested in internal correspondence, Belford said that “industry did not contact career staff working in EPA’s TRI program to lobby, pressure or express their preferences regarding the text of the 2020 NDAA or its implementation.”  

“EPA is not aware of whether industry contacted the political leadership of the agency that was in place at that time,” he added, reiterating that “EPA career staff are required to follow the direction of the political leadership.” 

Once President Biden took office, Belford said “it was an immediate priority” for both the administration and EPA career staff to designate the TRI-listed PFAS as chemicals of special concern — a decision he in part attributed to Freedhoff, who joined the OCSPP in January 2021. 

“In Dr. Freedhoff’s view, this was always the intent of Congress in passing the NDAA,” Belford added.

California regulators approve rules to curb methane leaks and prevent fires at landfills

California air regulators adopted new rules designed to reduce methane leaks and better respond to disastrous underground fires at landfills statewide.

In one of the most important state environmental decisions this year, California air regulators adopted new rules designed to reduce methane leaks and better respond to disastrous underground fires at landfills statewide. California Air Resources Board members voted 12-0 on Thursday to approve a batch of new regulations for the state’s nearly 200 large landfills, designed to minimize the release of methane, a powerful greenhouse gas produced by decomposing organic waste. Landfills are California’s second-largest source of methane emissions, following only the state’s large dairy cow and livestock herds.The new requirements will force landfill operators to install additional pollution controls; more comprehensively investigate methane leaks on parts of landfills that are inaccessible with on-the-ground monitoring using new technology like drones and satellites; and fix equipment breakdowns much faster. Landfill operators also will be required to repair leaks identified through California’s new satellite-detection program. The regulation is expected to prevent the release of 17,000 metric tons of methane annually — an amount capable of warming the atmosphere as much as 110,000 gas-fired cars driven for a year. It also will curtail other harmful landfill pollution, such as lung-aggravating sulfur and cancer-causing benzene. Landfill operators will be required to keep better track of high temperatures and take steps to minimize the fire risks that heat could create. There are underground fires burning in at least two landfills in Southern California — smoldering chemical reactions that are incinerating buried garbage, releasing toxic fumes and spewing liquid waste. Regulators found explosive levels of methane emanating from many other landfills across the state.During the three-hour Air Resources Board hearing preceding the vote, several Californians who live near Chiquita Canyon Landfill — one of the known sites where garbage is burning deep underground — implored the board to act to prevent disasters in other communities across the state.“If these rules were already updated, maybe my family wouldn’t be sick,” said Steven Howse, a 27-year resident of Val Verde. “My house wouldn’t be for sale. My close friend and neighbor would still live next door to me. And I wouldn’t be pleading with you right now. You have the power to change this.”Landfill operators, including companies and local governments, voiced their concern about the costs and labor needed to comply with the regulation. “We want to make sure that the rule is implementable for our communities, not unnecessarily burdensome,” said John Kennedy, a senior policy advocate for Rural County Representatives of California, a nonprofit organization representing 40 of the state’s 58 counties, many of which own and operate landfills. “While we support the overarching goals of the rule, we remain deeply concerned about specific measures including in the regulation.”Lauren Sanchez, who was appointed chair of the California Air Resources Board in October, recently attended the United Nations’ COP30 climate conference in Brazil with Gov. Gavin Newsom. What she learned at the summit, she said, made clear to her that California’s methane emissions have international consequences, and that the state has an imperative to reduce them. “The science is clear, acting now to reduce emissions of methane and other short-lived climate pollutants is the best way to immediately slow the pace of climate change,” Sanchez said.

Exoplanet atmospheres are a key to habitability

The habitable zone of a planet might be key to whether life can survive there. But so are exoplanet atmospheres, scientists say. The post Exoplanet atmospheres are a key to habitability first appeared on EarthSky.

Astronomers say exoplanet atmospheres are a key to whether or not life could survive on a planet. Image via NASA/ ESA/ Leah Hustak (STScI)/ Ralf Crawford (STScI)/ University of Montreal. Scientists focus on the habitable zone (where liquid water might exist) when they are gauging whether an exoplanet could be habitable. But exoplanet atmospheres are also key to whether a planet can maintain stable, life-supporting conditions. For life to persist on a planet, the environment must be stable. A planet’s surface, oceans and atmosphere can work together to regulate the system. By Morgan Underwood, Rice University EarthSky isn’t powered by billionaires. We’re powered by you.Support EarthSky’s 2025 Donation Campaign and help keep science accessible. Exoplanet atmospheres are a key to habitability When astronomers search for planets that could host liquid water on their surface, they start by looking at a star’s habitable zone. Water is a key ingredient for life, and on a planet too close to its star, water on its surface may boil. Too far, and it could freeze. This zone marks the region in-between. But being in this sweet spot doesn’t automatically mean a planet is hospitable to life. Other factors, like whether a planet is geologically active or has processes that regulate gases in its atmosphere, play a role. The habitable zone provides a useful guide to search for signs of life on exoplanets, or planets outside our solar system orbiting other stars. But what’s in these planets’ atmospheres holds the next clue about whether liquid water – and possibly life – exists beyond Earth. The greenhouse effect On Earth, the greenhouse effect, caused by gases like carbon dioxide and water vapor, keeps the planet warm enough for liquid water and life as we know it. Without an atmosphere, Earth’s surface temperature would average around 0 degrees Fahrenheit (-18 C), far below the freezing point of water. The boundaries of the habitable zone are defined by how much of a greenhouse effect is necessary to maintain the surface temperatures that allow for liquid water to persist. It’s a balance between sunlight and atmospheric warming. Many planetary scientists, including me, are seeking to understand if the processes responsible for regulating Earth’s climate are operating on other habitable-zone worlds. We use what we know about Earth’s geology and climate to predict how these processes might appear elsewhere. That is where my geoscience expertise comes in. Picturing the habitable zone of a solar system analog, with Venus- and Mars-like planets outside of the “just right” temperature zone. Image via NASA. Why the habitable zone? The habitable zone is a simple and powerful idea, and for good reason. It provides a starting point, directing astronomers to where they might expect to find planets with liquid water. But without needing to know every detail about the planet’s atmosphere or history. Its definition is partially informed by what scientists know about Earth’s rocky neighbors. Mars, which lies just outside the outer edge of the habitable zone, shows clear evidence of ancient rivers and lakes where liquid water once flowed. Similarly, Venus is currently too close to the sun to be within the habitable zone. Yet, some geochemical evidence and modeling studies suggest Venus may have had water in its past. Though how much and for how long remains uncertain. These examples show that while the habitable zone is not a perfect predictor of habitability, it provides a useful starting point. How to have a stable environment What the habitable zone doesn’t do is determine whether a planet can sustain habitable conditions over long periods of time. On Earth, a stable climate allowed life to emerge and persist. Liquid water could remain on the surface, giving slow chemical reactions enough time to build the molecules of life. This let early ecosystems develop resilience to change, which reinforced habitability. Life emerged on Earth, but continued to reshape the environments it evolved in, making them more conducive to life. This stability likely unfolded over hundreds of millions of years, as the planet’s surface, oceans and atmosphere worked together as part of a slow but powerful system to regulate Earth’s temperature. Recycling inorganic carbon A key part of this system is how Earth recycles inorganic carbon between the atmosphere, surface and oceans over the course of millions of years. Inorganic carbon refers to carbon bound in atmospheric gases, dissolved in seawater or locked in minerals, rather than biological material. This part of the carbon cycle acts like a natural thermostat. When volcanoes release carbon dioxide into the atmosphere, the carbon dioxide molecules trap heat and warm the planet. As temperatures rise, rain and weathering draw carbon out of the air and store it in rocks and oceans. If the planet cools, this process slows down. This allows carbon dioxide, a warming greenhouse gas, to build up in the atmosphere again. This part of the carbon cycle has helped Earth recover from past ice ages and avoid runaway warming. Even as the sun has gradually brightened, this cycle has contributed to keeping temperatures on Earth within a range where liquid water and life can persist for long spans of time. Similar cycles in exoplanet atmospheres? Now, scientists are asking whether similar geological processes might operate on other planets. And if so, how they might detect them. For example, if researchers could observe enough rocky planets in their stars’ habitable zones, they could look for a pattern connecting the amount of sunlight a planet receives and how much carbon dioxide is in its atmosphere. Finding such a pattern may hint that the same kind of carbon-cycling process could be operating elsewhere. The mix of gases in a planet’s atmosphere is shaped by what’s happening on or below its surface. One study shows that measuring atmospheric carbon dioxide in a number of rocky planets could reveal whether their surfaces are broken into a number of moving plates, like Earth’s, or if their crusts are more rigid. On Earth, these shifting plates drive volcanism and rock weathering, which are key to carbon cycling. Simulation of what space telescopes, like the Habitable Worlds Observatory, will capture when looking at distant solar systems. Image via STScI/ NASA GSFC. Keeping an eye on distant exoplanet atmospheres The next step will be toward gaining a population-level perspective of planets in their stars’ habitable zones. By analyzing atmospheric data from many rocky planets, researchers can look for trends that reveal the influence of underlying planetary processes, such as the carbon cycle. Scientists could then compare these patterns with a planet’s position in the habitable zone. Doing so would allow them to test whether the zone accurately predicts where habitable conditions are possible, or whether some planets maintain conditions suitable for liquid water beyond the zone’s edges. This kind of approach is especially important given the diversity of exoplanets. Many exoplanets fall into categories that don’t exist in our solar system. These include super Earths and mini Neptunes. Others orbit stars smaller and cooler than the sun. NASA’s Habitable Worlds Observatory The datasets needed to explore and understand this diversity are just on the horizon. NASA’s upcoming Habitable Worlds Observatory will be the first space telescope designed specifically to search for signs of habitability and life on planets orbiting other stars. It will directly image Earth-sized planets around sunlike stars to study their atmospheres in detail. Instruments on the observatory will analyze starlight passing through these atmospheres to detect gases like carbon dioxide, methane, water vapor and oxygen. As starlight filters through a planet’s atmosphere, different molecules absorb specific wavelengths of light, leaving behind a chemical fingerprint that reveals which gases are present. These compounds offer insight into the processes shaping these worlds. The Habitable Worlds Observatory is under active scientific and engineering development, with a potential launch targeted for the 2030s. Combined with today’s telescopes, which are increasingly capable of observing atmospheres of Earth-sized worlds, scientists may soon be able to determine whether the same planetary processes that regulate Earth’s climate are common throughout the galaxy, or uniquely our own. NASA’s planned Habitable Worlds Observatory will look for exoplanets that could potentially host life.

Some California landfills are on fire and leaking methane. Newly proposed rules could make them safer

California is considering adopting new rules to better identify and more quickly to respond to dangerous methane leaks and underground fires at landfills statewide.

A vast canyon of buried garbage has been smoldering inside a landfill in the Santa Clarita Valley, inducing geysers of liquid waste onto the surface and noxious fumes into the air.In the Inland Empire, several fires have broken out on the surface of another landfill. In the San Fernando Valley, an elementary school has occasionally canceled recess due to toxic gases emanating from rain-soaked, rotting garbage from a nearby landfill. And, in the San Francisco Bay Area, burrowing rodents may be digging into entombed trash at a landfill-turned-park, unloosing explosive levels of methane.These are just a few of the treacherous episodes that have recently transpired at landfills in California, subjecting the state’s waste management industry to growing scrutiny by residents and regulators.Landfill emissions — produced by decaying food, paper and other organic waste — are a major source of planet-warming greenhouse gases and harmful air pollution statewide. But mismanagement, aging equipment and inadequate oversight have worsened this pollution in recent years, according to environmental regulators and policy experts.This week, the California Air Resources Board will vote on adopting a new slate of requirements to better identify and more quickly respond to methane leaks and disastrous underground fires at large landfills statewide.The proposal calls for using satellites, drones and other new technologies to more comprehensively investigate methane leaks. It also would require landfill operators to take corrective action within a few days of finding methane leaks or detecting elevated temperatures within their pollution control systems.In recent years, state regulators have pinpointed at least two landfills in Southern California experiencing “rare” underground landfill fires — largely uncontrollable disasters that have burned troves of buried garbage and released toxic fumes into the air. More recently, a new state satellite program has detected 17 methane plumes from nine landfills between July and October, potentially leaking the flammable gas into unwanted areas and contributing to climate change.Proponents of the proposed rule say the added oversight could help reduce California’s second-largest source of methane, a potent greenhouse gas that warms the atmosphere much more than carbon dioxide. It could also bring relief to hundreds of thousands of people who live nearby landfills and may be exposed to toxic pollutants like hydrogen sulfide or benzene.“Curbing methane emissions is a relatively quick and cost-effective way to reduce the greenhouse pollution that’s wreaking havoc with our climate,” said Bill Magavern, policy director at the Coalition for Clean Air. “But [we’ve] also been involved in updating and strengthening the rule because we’re seeing the community impacts of leaking landfills, particularly at places like Chiquita Canyon, where we have a landfill fire that is making people in the community sick.”Nearly 200 landfills statewide would be subject to the proposed requirements — 48 are privately owned and 140 are government-owned.Many landfill operators oppose the rule, saying the new requirements would saddle the industry with an untenable workload and millions of dollars each year in added costs. These costs could be passed on to residents, whose garbage fees have already risen significantly in recent years.Sacramento County officials, who operate the Kiefer Landfill, said the proposed protocols were not feasible. “As a public landfill, Kiefer cannot quickly adapt to regulatory shifts of this magnitude, and these increased costs would ultimately burden the community it serves,” Sacramento County officials wrote in a Nov. 10 letter to the state Air Resources Board.The vast majority of landfills are already required to monitor for leaks and operate a gas collection system — a network of wells that extend deep into the layers of buried waste to capture and destroy methane.A hot messChiquita Canyon Landfill in Castaic has become the poster child for the issues plaguing California’s waste management system.A blistering-hot chemical reaction began inside the landfill’s main canyon in May 2022, roasting garbage in a roughly 30-acre area.Starting in April 2023, residents of Castaic and nearby Val Verde began to take notice. They called in thousands of odor complaints to the South Coast Air Quality Management District, with many citing headaches, nausea, nosebleeds and difficulty breathing.Later that year, state regulators learned that the landfill’s temperatures had risen above 200 degrees, melting plastic pipes used to collect landfill gases. An air district inspector also witnessed geysers of liquid waste bursting onto the surface and white smoke venting from large cracks spreading across the reaction area.Air sampling found elevated levels of lung-aggravating sulfur pollutants and cancer-causing benzene. Air samples in 2023 detected benzene concentrations more than eight times higher than the state’s short-term health limit at Hasley Canyon Park, which abuts Live Oak Elementary School, alarming local parents.“I personally have transferred my children to different schools further away,” said Jennifer Elkins, a Val Verde resident whose children attended Live Oak. “I spend three hours a day driving my kids to and from school. The commute has been a sacrifice, but it’s also been well worth it, because I know my children are breathing cleaner air, and I have seen their health improve.”The landfill, owned by Texas-based Waste Connections, installed new heat-resistant equipment to extract liquid waste in an attempt to reduce broiling temperatures. It also installed a large covering over the affected area to suppress odors. It permanently closed and ceased accepting waste this year.Still, the reaction area has tripled in size and could consume the entire 160-acre canyon for many more years. During other underground landfill fires, elevated temperatures have persisted for more than a decade.The issue is, once these broiling temperatures start consuming landfill waste, there’s little that landfill operators can do to snuff them out.The fumes from Chiquita Canyon have pushed some longtime residents to consider moving. After more than 25 years in Val Verde, Abigail DeSesa is contemplating starting anew somewhere else.“This is our life’s investment — our forever home that we were building for retirement and on the verge of paying off,” DeSesa said. “And we may have to start over.”“I don’t know that I can outlast it,” DeSesa added.Chiquita Canyon is not alone.Earlier this year, the South Coast air district learned about another fiery chemical reaction brewing inside El Sobrante Landfill in Corona. In August, Waste Management, the landfill’s owner and operator, acknowledged there was a two-acre “area of concern” where landfill staff had observed temperatures climbing above 200 degrees. Riverside County inspectors also found several fires had ignited on the landfill’s surface in recent years, according to public records.Environmental advocates fear that many more landfills may be on the precipice of these largely unmanageable disasters.According to an analysis by California Communities Against Toxics, there are 18 landfills in California that have had prolonged heat signatures detected by NASA’s Fire Information for Resource Management System, an online tool using satellite instruments to detect fires and thermal anomalies.At least 11 of these landfills requested and received permission from either federal or local environmental regulators to continue operating with higher temperatures than currently allowed, according to public records obtained by the environmental organization.These regulatory exemptions are part of the problem, said Jane Williams, the group’s executive director.“We have 11 landfills across California that have been granted waivers by the government to basically ‘hot rod’ the landfill,” Williams said. “We would really like EPA and state agencies to stop granting landfill waivers. It’s a permission slip to speed in a school zone.”Under newly proposed revisions to state rules, operators must be more transparent in disclosing the temperatures in their gas collection systems. If operators detect elevated temperatures, they must take action to minimize the amount of oxygen in the landfill.While these rule changes might be coming too late to fix the issues near Chiquita Canyon, locals hope it will help others who live in the orbit of the nearly 200 other large landfills in California that could be subject to these rules.“While there’s still a fight here to try to address the concerns at Chiquita Canyon Landfill, we know that there’s an opportunity to really prevent this kind of disaster from happening anywhere else in our state,” said Assemblymember Pilar Schiavo.Dangerous leaksMeanwhile, many other landfills are releasing unsafe amounts of methane, an odorless gas produced by bacteria that break down organic waste.These emissions present two critical issues.First, methane is a powerful greenhouse gas — capable of warming the atmosphere 80 times more than the same amount of carbon dioxide over 20 years. Following California’s large dairy and livestock operations, landfills emit the second-most methane statewide.Second, methane is the primary constituent in natural gas. It can ignite or explode at certain concentrations, presenting a serious safety risk in the event of uncontrolled releases. Several times over the last few years, regulators have detected potentially explosive concentrations in the air and shallow soil near several landfills.Under current landfill regulations, operators are required to monitor for excessive methane leaks four times a year. Many operators hire contractors to walk across accessible portions of the landfill with a handheld leak-monitoring device, an approach that some environmental advocates say is unreliable.In addition, some areas of the landfill are not screened for methane leaks if operators consider them to be unsafe to walk across, due to, for example, steep hills or ongoing construction activities.“Landfills have to monitor surface emissions, but they do that in a very inefficient way, using outdated technology,” Magavern said.Starting this past summer, California has partnered with the nonprofit organization Carbon Mapper to use satellites to detect methane leaks, and already has found 17 coming from landfills. In one case, researchers saw a large methane plume appear to emanate from Newby Island Landfill in San José and drift into a nearby residential neighborhood.Although the state has notified these landfill operators, it currently cannot require them to repair leaks detected via satellite. That would change under the proposed amendments to the state’s landfill regulations. Operators would also have to use state-approved technology to routinely scan portions of their landfills they deem inaccessible.The proposed amendments seek to prevent the most common causes of methane emissions. A series of surveys of landfill operators found 43% of leaks in recent years were caused by one or more of a facility’s gas collection wells being offline at the time.The new rules would require that such wells can only be offline for up to five days at a time for repairs. Operators would also be required to install gas collection systems within six months of when garbage is first placed in a new part of a landfill — rather than the 18-month time frame currently allowed.In addition, landfills would be forced to take actions to fix a leak within three days of detection, rather than 10 days. In theory, that should help reduce the risk of leaks from things like cracks in landfill covers (typically a layer of soil or plastic covering) and damaged components of gas collection systems — two other major sources of leaks that landfill operators have reported.The amended landfill rules could collectively cost private companies and local governments $12 million annually.Some say that’s well worth the cost.A contingent of residents who live near Chiquita Canyon Landfill are flying to Sacramento to attend the state Air Resources Board meeting. They are expected to testify on how the fire and landfill emissions have unraveled the fabric of the semi-rural community.Elkins, the Val Verde resident, appreciated the area’s natural beauty — picturesque hillsides, wildlife and opportunities for stargazing without bright city lights. However, now her family hardly spends any time outdoors due to the noxious odors.Some of her neighbors have moved away, but Elkins and many other longtime locals cannot, no matter how they fear for their health and safety. “The homes are not selling,” she said. “Other homes sit vacant, and community members are paying two mortgages just to get away. And for many of us, it would be financial suicide to move away and start over somewhere new.”

New Texas petrochemical facilities are mostly in low income areas, communities of color, study finds

Researchers evaluated the neighborhoods around 89 proposed or expanding petrochemical facilities across the state using a screening tool from the EPA.

Phillip)A recent report from Texas Southern University found that new and expanding petrochemical facilities in Texas are overwhelmingly located in low-income neighborhoods and communities of color. Researchers evaluated the neighborhoods around 89 proposed or expanding petrochemical facilities across the state using a screening tool from the Environmental Protection Agency. They looked at air pollution and proximity to other "hazardous facilities" in the areas. Data related to the race, education, income level and languages within the areas was also collected. Sign up for the Hello, Houston! daily newsletter to get local reports like this delivered directly to your inbox. "The communities that are on the fenceline are getting pollution and they also are getting poverty," said Robert Bullard, one of the study's authors. "And also, if you look at the infrastructures within those neighborhoods that have these facilities, they are of poor quality." The report found that 9 in 10 of the facilities are located in counties with "higher demographic vulnerability" – meaning they had more people of color, more low-income residents, or both, compared to the state and national averages. Over half of the new facilities were slated to be built in communities that have a higher proportion of people of color than the national average. Meanwhile, 30% of the facilities were slated to be built in areas with a poverty rate higher than the national average. "Segregation and racial redlining actually segregated pollution, and it segregated people," Bullard said. The analysis also found that the proposed facilities were being built in areas that are already struggling with air pollution. About 1 in 5 of the proposed facilities are located within the top 10% of areas nationwide with the highest amount of particulate matter pollution, and 46% of the new facilities are slated to be built within the top 10% of communities across the country with the highest amount of air toxins. The facilities were concentrated in 9% of Texas counties, with nearly half of them located in Harris County or Jefferson County.
