A reported inbox and presidential proclamations granted Clean Air Act pauses, benefiting polluters while critics warn health safeguards were sidelined.
The most consequential environmental exemptions granted under Donald Trump’s Clean Air Act initiative appear to have started with a simple instruction: ask, by email.
In March 2025, the Trump administration floated a proposal to coal-fired power plants, chemical manufacturing facilities and other industrial operators.. Their operations could receive exemptions from key Clean Air Act requirements—rules critics say have helped prevent thousands of premature deaths—if they requested relief.. The offer did not require a detailed. technical application; an email submitted within a short window was reported to be sufficient.
Within two weeks. executives from major industries began sending requests through an email inbox set up to route exemption requests from the Environmental Protection Agency to the White House.. According to the report. at least 3. 000 pages of emails were exchanged in the following weeks. providing a detailed look at how the administration’s EPA describes as its “biggest deregulatory action in U.S.. history.”
One early message came from Richard Shaffer. an asset manager at Scrubgrass Reclamation Company. who sought an exemption covering a western Pennsylvania power plant that burns coal waste.. Shaffer’s note to the government emphasized that some of the electricity generated by the facility is used to mine bitcoin. and argued that keeping compliance costs low was important “for the security of the United States.” A presidential proclamation granting the exemption was reported to arrive 11 days later.
Other requests followed.. A Citgo Petroleum Corporation lawyer. Ann Al-Bahish. asked for exemptions involving petroleum refineries in Illinois. Louisiana and Texas that had faced Clean Air Act violations in recent years.. The administration previously concluded that the rule at issue would deliver critical health protections to hundreds of thousands of people living near chemical plants. and Citgo reportedly agreed to install new pollution controls to resolve some of its violations.. In a later development reported as a July proclamation, exemptions were also approved.
For companies tied to industrial emissions with known health risks, exemption requests were likewise granted.. Kevin Wagner. vice president of Sterigenics—an industrial medical sterilizer company—messaged that nine facilities emitting ethylene oxide. including sites near Salt Lake City. Los Angeles. Charlotte and Atlanta. should be exempted.. Federal data cited in the report says more than 45. 000 people. most of them not white. live within a mile of those facilities.. Those requests were reported to receive approval through July proclamations.
The report says the White House did not solicit input from EPA scientists when granting the exemptions and that the administration cited Clean Air Act authority that it said had never been used before.. More than 180 facilities across 38 states and Puerto Rico were reported to be given a two-year reprieve from complying with updated Clean Air Act rules.. The same reporting indicates roughly 250,000 people live within a mile of those facilities, based on EPA and U.S.. Census Bureau data collected by the Environmental Defense Fund.
A majority of the exempted operations were described as coal power plants and medical sterilizers.. The report also indicates that more than 70 of the facilities had faced formal EPA enforcement action in the preceding five years for issues including emissions above regulatory limits and failures to properly track pollution.
The administration’s process also left gaps in public disclosure, according to the report.. It says few requests appear to have been denied. while the administration did not publicly publish decisions for three categories of plants it said it would consider exempting: manufacturers of rubber tires. iron and steel. and lime—materials used across industries ranging from metals to concrete.. The report adds that Republicans in Congress had already repealed a rubber tire updated rule.
An EPA spokesperson. in a statement provided in response to the investigation. said EPA “played no role in the determinations set out in the statute” and that authority was “specifically vested in the President.” The spokesperson said requests sent to the EPA’s electronic mailbox were forwarded to the White House.
In justifying the exemptions. the White House cited standards in the Clean Air Act that it said require a president to invoke national security and contend that the technology needed to meet EPA requirements is unavailable.. In the report. a White House spokesperson argued that maintaining Biden-era requirements could shut down businesses. framing the exemptions as regulatory relief due to national security concerns and criticizing the requirements as burdensome.
Not all experts accept that framing.. The report says multiple policy experts told it they do not believe the White House’s justifications hold up.. It also notes that some utilities said publicly they were already implementing pollution controls that would allow compliance. undercutting the argument that relevant technology does not exist.
Community groups and environmental nonprofits have challenged the exemptions in court. the report says. filing five lawsuits aimed at halting them.. A coalition of 12 organizations described the action as an “illegal scheme.” The report states that four cases have been consolidated and are ongoing. and that in motions to dismiss. the administration argued the groups lacked legal standing and reiterated that the law gives the president authority to grant the exemptions.
The effect is not abstract.. The report describes how a Freeport-McMoRan copper mining and smelting operation in eastern Arizona—near the towns of Miami. Claypool and Globe—was affected by a Clean Air Act rule updated in 2024.. It says EPA concluded that implementing the updated rule would reduce emissions of toxic metals. primarily lead and arsenic. by nearly 50 percent at the country’s copper smelters.. It also says the administration later paused implementation of the rule and approved the company’s request for an exemption that let the plant avoid the rule’s deadlines.
In the account. shortly after the exemption. white smoke was reported rising from the smelter. with neighbors describing familiar health patterns from the era before tighter regulations.. The report includes the perspective of Trina Bunger. who says that decades ago her children wore handkerchiefs over their mouths during school and that family cattle fell ill. prompting her to doubt earlier assumptions about the cause of sickness.. It contrasts those memories with improvements Bunger said she has seen over time as emissions controls tightened. and it notes that Freeport spent $250 million on improvements completed in 2017 to better control sulfur dioxide.
The report links the exemption process to a claim that compliance costs would outweigh the potential emission reductions.. Freeport’s vice president and senior counsel reportedly emailed the EPA in March 2025 to request a reprieve. arguing that complying with the copper smelter rule could cost hundreds of millions of dollars while offering minimal emissions reductions.. Freeport’s spokesperson said the company had made investments to manage sulfur dioxide. lead and other regulated emissions and that it increased monitoring around the smelter while requesting additional time to work with the EPA on alleged “flaws” in the updated rule.
The administration’s approach has also faced political pushback.. In April, U.S.. Sens.. Sheldon Whitehouse and Adam Schiff introduced legislation that would require Congress’ consent before a president could pause Clean Air Act compliance.. Whitehouse characterized the exemption effort as an abuse of loopholes that would allow companies to pollute without regard for health consequences.
Beyond individual plants, the report argues the exemptions fit into a broader deregulatory direction.. It says the pause gives companies extra time—described as two years—to comply with updates to nine sets of Clean Air Act regulations governing lower emissions or monitoring in specific industries.. It adds that those updates were set to take effect in 2025 and 2026.
It also describes a larger strategy to dismantle parts of the Clean Air Act framework. weakening rules on everything from ethylene oxide emissions to plastics pyrolysis plants.. The report further says the rollback undermined actions tied to climate change. including efforts that had been used to treat greenhouse gas emissions like carbon dioxide as regulated pollutants.
Coal regulation appears to be a central target, the report states.. It says Trump granted 71 coal power plants two-year exemptions to the Clean Air Act rule known as the Mercury and Air Toxics Standards.. It then reports that in February the administration formalized the rollback of those standards, making the exemptions permanent.
Among the cases highlighted is Ameren Corp.’s Labadie Energy Center west of St.. Louis.. The report describes the plant as a large coal-fired facility and notes that EPA data cited in the account indicates it is one of the largest sources of sulfur dioxide. a driver of haze that can harm respiratory health. and also a major source of carbon dioxide.. A Sierra Club and Clean Air Task Force analysis of EPA data. the report says. links the plant to more than 300 premature deaths per year.
For residents, the stakes are personal.. Patricia Schuba’s family has lived in Franklin County for five generations. and she says she can see the plant and observes “black clouds” even on days that seem otherwise normal.. She serves as president of the Labadie Environmental Organization and says she keeps track of relatives and friends who have suffered cancer. respiratory illness and other diseases.. Her comments in the report tie the promise of deregulation to fear that the plant will remain operating for years to power data centers.
A Sierra Club attorney, Sunil Bector, is quoted in the report describing how heavily polluting facilities can benefit from overlapping regulatory rollbacks, arguing that removing regulatory levers shifts the costs of pollution back onto people who breathe the air.
Ameren’s director of environmental services. Craig Giesmann. responded in a statement. saying the Labadie facility provides electricity in a cost-effective manner. operates in compliance with applicable environmental regulations designed to protect public health. and is supported by decades of emissions-control investments.. He also described the plant as “critical infrastructure.”
The report places the exemption fight within a national energy framing as well.. It says the president is required to tie exemptions to national security and that Trump has declared a national energy emergency. citing fears emerging industries such as artificial intelligence will not have enough electricity.. It notes that proposals for data centers have surfaced in Franklin County and that the county voted to recommend one despite opposition from hundreds of residents.
Louisiana communities, meanwhile, are described as facing a renewed risk from the exemptions.. The report says an 85-mile stretch southeast from Baton Rouge has long been known for heavy industry and has earned the label “Cancer Alley.” It notes studies indicating elevated cancer rates in the region and adds that local chemical plants received exemptions from Clean Air Act rules.. Louisiana is reported to host 20 of the exempted facilities. with Texas and Pennsylvania ranking first and third by number of exempted facilities.
In the account. Tonga Nolan recalls a childhood neighborhood on Baton Rouge’s north side and says she remembers when “death started to come.” She lists neighbors and family members who died of cancer and says she later moved away after undergoing a hysterectomy. attributing her illness concerns to emissions from nearby facilities.. She is reported to be in remission.
The report also describes the role of Formosa Plastics, which produces PVC.. It notes the company’s history of violations. including a 2003 release of carcinogenic vinyl chloride into Baton Rouge. citing findings from the U.S.. Chemical Safety and Hazard Investigation Board.. It also says EPA data show continued patterns of reported infractions in recent years.. A company spokesperson told the report that “significant improvements” have been made since the 2003 incident. related to process safety. monitoring and operational controls.
Formosa Plastics’ Baton Rouge plant reportedly sought an exemption to a Clean Air Act rule and asked for more time to design and install technology to comply.. The company’s executives argued that the plastic produced at the facility is important to national security because it is used in products including blood bags.. The report says the request, granted in July, covered emission limits and standards, performance testing, monitoring, recordkeeping and reporting requirements.. It also notes that the rule would have required improved fence-line monitoring. designed to detect toxic gas leaks from pipelines. valves and tanks.
The report says monitoring has proven effective elsewhere, citing an example from the EPA: fence-line emissions of benzene, described as a carcinogen, fell 30% at petroleum refineries after implementation of a similar monitoring program.
Historical disparities are central to the human impact described.. The report states that about 54% of the people living within a mile of the exempted facilities are not white. according to federal data collected by the Environmental Defense Fund. compared with about 43% of the U.S.. population not white overall.. Nolan described the loss among neighbors as difficult to live with. saying it feels like “a hole that can never be filled.”
Alongside the health consequences, the report portrays procedural disorder.. Because presidents had never previously used the authority in the way described. experts said companies were left unclear about how to request an exemption.. The report includes examples: at least one businessman wrote asking how to begin as a gas company seeking an exemption. while another email mocked the rollback by proposing a new coal plant built on an offshore mangrove island near Mar-a-Lago.
Trade groups representing chemical manufacturers. including the American Chemistry Council and the American Fuel & Petrochemical Manufacturers. reportedly asked for a blanket exemption for roughly 640 member companies.. The groups’ letter warned that without immediate intervention companies might consider shutting down units or shifting operations offshore to avoid what they characterized as an imprudent and unlawful rule.
The report also says the administration later clarified that companies needed to submit requests themselves. and that even rank-and-file EPA staff reportedly had limited understanding of the process.. Internal EPA communications. obtained for the report. suggested that a political appointee with prior utility and petrochemical trade-group experience helped design the inbox.
In addition. the report states that presidential proclamations published exemptions on the White House website and included language declaring national security interests.. It also describes confusion created when at least one proclamation listed a facility’s location incorrectly—one case where a plant south of Baton Rouge was described as being in Alabama rather than Louisiana—and another exemption that may have involved a plant that does not exist.
Spelling mistakes and formatting errors, the report says, have made identifying exempted plants difficult.. It cites misspellings involving an Arkansas coal plant and the name Phillips 66. which the report says received exemptions for oil refineries in Illinois and Texas.. Phillips 66 declined to comment in the report.
Taken together, the exemptions described in the report reach far beyond courtroom filings and presidential proclamations.. They touch the daily lives of residents in towns near industrial facilities and the policy choices shaping U.S.. air quality rules for years.. For critics. the evidence suggests not only a weakening of health protections. but a shortcut in governance—one that they say bypassed the kinds of expert review and public oversight that typically accompany regulation under the Clean Air Act.
For communities already burdened by pollution. the result is a continued struggle to connect environmental risk to the illnesses they see.. For industry supporters. the exemptions represent the ability to keep facilities running amid legal and technological requirements they say are burdensome.. And for lawmakers. the dispute has now extended into Congress. where at least one proposal would require congressional consent before the president can pause Clean Air Act compliance.
