Disbanded Air Pollution Panel Finds EPA Standards Don’t Protect Public Health

By Gretchen Goldman
The Independent Particulate Matter Review Panel has released their consensus recommendations to the EPA administrator on the National Ambient Air Quality Standards for Particulate Matter. The group of 20 independent experts, that were disbanded by Administrator Wheeler last October and reconvened last week, hosted by the Union of Concerned Scientists, has now made clear that the current particulate pollution standards don't protect public health and welfare.
The Clean Air Scientific Advisory Committee (CASAC) — the remaining seven-person committee that is providing science advice to the EPA on the particulate matter standards — meets this week to discuss their recommendations on whether the current standards are adequate. The letter from the Independent Panel will be the elephant in the room.
The Elephant in the CASAC Meeting
CASAC has already acknowledged that they don't have the expertise to conduct the review but you know who does? The Independent Panel. The Panel has more than double the experts of CASAC, and importantly, it has multiple experts in each of the necessary scientific disciplines critical to ensure a comprehensive, robust review of the science supporting the standards.
As a result, we should watch whether or not CASAC aligns with the panel in their recommendations on the standards. If CASAC doesn't decide this week to make a similar recommendation as the Independent Panel, they'll have to explain why they disagreed with a larger, more experienced, and more diverse set of experts on the topic. In any event, the administrator will have access to both CASAC and the Independent Panel's recommendations when he ultimately makes the decision of where to set particulate pollution standards. The panel's recommendations should hold the administrator's feet to the fire.
The Fine Particulate Matter Standards Don’t Protect Public Health
The standards of greatest interest are the primary PM2.5 standards. These are the standards for particulate matter less than 2.5 micrometers (fine particulate matter) that are designed to protect public health. The panel supported the preliminary conclusions of a Draft EPA Policy Assessment that the current standards aren't requisite to protect public health.
The letter cited new and consistent epidemiological findings, supported by human and animal studies and other studies with natural experiments, as providing "clear and compelling scientific evidence" for tighter standards. Since the last particulate matter review, several new large-scale epidemiological studies provide powerful evidence that particulate matter is causing adverse health outcomes (such as early death, heart attacks, and respiratory stress) at locations and during time periods with concentrations at or below the level of the current standards.
They write, "New and compelling evidence that health effects are occurring in areas that already meet or are well below the current standards." Notably, this evidence cuts across different locations with different study populations, different study designs, and different statistical approaches.
Given the weight of the evidence from new studies across scientific disciplines and consistent with the decision-making process that EPA and its science advisers have used for many years, the panel recommends a particulate matter standard between 8 µg/m3 and 10 µg/m3 for the annual PM2.5 standard (compared to the current standard of 12 µg/m3) and between 25 µg/m3 and 30 µg/m3 for the 24-hour standard (compared to the current standard of 35 µg/m3) to protect public health. These ranges are tighter than those recommended in EPA's Draft Policy Assessment.
Keeping the Current Fine Particulate Matter Standards Ignores the Science
The Independent Panel rejected a potential argument for maintaining the current primary PM2.5 standards. The Draft Policy Assessment offered up an alternative rationale that might be used if the agency were to reject the draft assessment's recommendation to strengthen the standards and maintain the current standards. This alternative rationale explains that such a move would require the administrator to be arbitrarily selective in choosing which new studies to accept and which to toss and to disregard new epidemiologic evidence showing effects at lower levels.
The panel roundly rejected this justification, noting that, "Arguments offered in the draft Policy Assessment for retaining the current standards are not scientifically justified and are specious." This is important because if the administrator fails to strengthen the standards, he'll have to explain (both in court and in the court of public opinion) why he feels such a decision is science-based, as required under the Clean Air Act. And one proposed argument he could use has just been debunked by this expert Panel.
Otherwise, the EPA’s Draft Policy Assessment Is Scientifically Sound
While the Independent Panel critiqued some details of the EPA's Draft Policy Assessment, the panel agreed that the draft science and policy assessments were cohesive and robust and the panel commended the "good faith effort" involved in the policy assessment. Specifically, the panel affirmed the use of EPA's causality framework used in the Integrated Science Assessment they reviewed last year and the Policy Assessment's new use of a hybrid modeling technique that allows for better assessment of risk from particulate matter exposure across the country especially in rural areas.
This diverges from what the seven-member CASAC has said and done around the EPA's assessment of the science and policy. In December, they concluded that the agency's draft science assessment was not a scientific document (it is) and CASAC Chair Dr. Tony Cox has been critical of the agency's causality framework that has been developed with dozens of experts over more than a decade. This view is not shared by the scientific community, and now, not shared by the Independent Panel either.
Other Particulate Pollution Standards Also May Need Revamping
The Independent Panel decided other particulate standards were also inadequate. On PM10, particulate matter less than 10 micrometers, the panel recommended revising this standard downward given that the PM2.5 component would also be tightened and noted several research and monitoring areas that need further work. On the secondary standards, i.e. the standards designed to protect welfare effects, such as visibility, the panel concluded that the standards should be tightened in order to be more protective.
The Panel Condemns the EPA’s Broken Process
The Independent Panel's deliberations, demands for further research, and unanswered questions highlight how broken the EPA process is. In a normal review cycle, the panel would have had the opportunity to talk with agency scientists directly. The EPA staff would then have considered their comments and revised the Integrated Science Assessment in response to the committee and panel's suggestions. But because the administrator disbanded the panel and abbreviated the process, there was no opportunity for such dialogue and refinement of the agency's science assessment before policy decisions were discussed. But alas, the panel had to make do with what was available to them and CASAC does too.
Fortunately for CASAC, an Independent Panel has already done their job, and they are free (and encouraged) to run with it, especially given the long list of ways that EPA Administrator Wheeler has damaged the ambient air pollution review process.
Listen and watch this week as CASAC discusses the same questions that the Independent Panel did last week. If CASAC comes to different conclusions than the larger, more experienced, and more diverse Independent Panel, we should ask why.
You can raise these questions yourself and demand that the administrator follow the panel's recommendations, by providing written or oral public comments at a future CASAC meeting and commenting on the docket for the particulate matter rule-making. I'll be providing public comments this afternoon urging CASAC to follow the advice of the Independent Panel and commenting on the EPA's problematic process and drawing attention to that elephant in the room.

A bill that would have banned fracking in California died in committee Tuesday.
The bill, SB467, would have prohibited fracking and other controversial forms of oil extraction. It would also have banned oil and gas production within 2,500 feet of a home, school, hospital or other residential facility. The bill originally set the fracking ban for 2027, but amended it to 2035, The AP reported.
"Obviously I'm very disappointed," State Sen. Scott Wiener (D-San Francisco), one of the bill's two introducers, told the Los Angeles Times. "California really has not done what it needs to do in terms of addressing the oil problem. We have communities that are suffering right now, and the Legislature has repeatedly failed to act."
The bill was introduced after California Gov. Gavin Newsom said he would sign a fracking ban if it passed the legislature, though his administration has continued to issue permits in the meantime, Forbes reported. Newsom has also spoken in favor of a buffer zone between oil and gas extraction and places where people live and learn, according to the Los Angeles Times. The latter is a major environmental justice issue, as fossil fuel production is more likely to be located near Black and Latinx communities.
Urban lawmakers who want California to lead on the climate crisis supported the bill, while inland lawmakers in oil-rich areas concerned about jobs opposed it. The oil and gas industry and trade unions also opposed the bill.
This opposition meant the bill failed to get the five votes it needed to move beyond the Senate's Natural Resources and Water Committee. Only four senators approved it, while Democrat Sen. Susan Eggman of Stockton joined two Republicans to oppose it, and two other Democrats abstained.
Eggman argued that the bill would have forced California to rely on oil extracted in other states.
"We're still going to use it, but we're going to use it from places that produce it less safely," Eggman told The AP. She also said that she supported the transition away from fossil fuels, but thought the bill jumped the gun. "I don't think we're quite there yet, and this bill assumes that we are," she added.
Historically, California has been a major U.S. oil producer. Its output peaked in 1986 at 1.1 million barrels a day, just below Texas and Alaska, according to Forbes. However, production has declined since then making it the seventh-most oil-producing state.
Still, California's fossil fuel industry is at odds with state attempts to position itself as a climate leader.
"There is a large stain on California's climate record, and that is oil," Wiener said Tuesday, according to The AP.
Wiener and Democrat co-introducer Sen. Monique Limón from Santa Barbara vowed to keep fighting.
"While we saw this effort defeated today, this issue isn't going away," they wrote in a joint statement. "We'll continue to fight for aggressive climate action, against harmful drilling, and for the health of our communities."

World's 5% 'Polluter Elite' Responsible for 37% of Global Emissions Growth, Study Concludes
By Brett Wilkins
As world leaders prepare for this November's United Nations Climate Conference in Scotland, a new report from the Cambridge Sustainability Commission reveals that the world's wealthiest 5% were responsible for well over a third of all global emissions growth between 1990 and 2015.
The report, Changing Our Ways: Behavior Change and the Climate Crisis, found that nearly half the growth in absolute global emissions was caused by the world's richest 10%, with the most affluent 5% alone contributing 37%.
"In the year when the UK hosts COP26, and while the government continues to reward some of Britain's biggest polluters through tax credits, the commission report shows why this is precisely the wrong way to meet the UK's climate targets," the report's introduction states.
The authors of the report urge United Kingdom policymakers to focus on this so-called "polluter elite" in an effort to persuade wealthy people to adopt more sustainable behavior, while providing "affordable, available low-carbon alternatives to poorer households."
The report found that the "polluter elite" must make "dramatic" lifestyle changes in order to meet the UK's goal — based on the Paris climate agreement's preferential objective — of limiting global heating to 1.5°C, compared with pre-industrial levels.
In addition to highlighting previous recommendations — including reducing meat consumption, reducing food waste, and switching to electric vehicles and solar power — the report recommends that policymakers take the following steps:
- Implement frequent flyer levies;
- Enact bans on selling and promoting SUVs and other high polluting vehicles;
- Reverse the UK's recent move to cut green grants for homes and electric cars; and
- Build just transitions by supporting electric public transport and community energy schemes.
"We have got to cut over-consumption and the best place to start is over-consumption among the polluting elites who contribute by far more than their share of carbon emissions," Peter Newell, a Sussex University professor and lead author of the report, told the BBC.
"These are people who fly most, drive the biggest cars most, and live in the biggest homes which they can easily afford to heat, so they tend not to worry if they're well insulated or not," said Newell. "They're also the sort of people who could really afford good insulation and solar panels if they wanted to."
Newell said that wealthy people "simply must fly less and drive less. Even if they own an electric SUV, that's still a drain on the energy system and all the emissions created making the vehicle in the first place."
"Rich people who fly a lot may think they can offset their emissions by tree-planting schemes or projects to capture carbon from the air," Newell added. "But these schemes are highly contentious and they're not proven over time."
The report concludes that "we are all on a journey and the final destination is as yet unclear. There are many contradictory road maps about where we might want to get to and how, based on different theories of value and premised on diverse values."
"Promisingly, we have brought about positive change before, and there are at least some positive signs that there is an appetite to do what is necessary to live differently but well on the planet we call home," it states.
The new report follows a September 2020 Oxfam International study that revealed the wealthiest 1% of the world's population is responsible for emitting more than twice as much carbon dioxide as the poorest 50% of humanity combined.

It may come as a surprise to realize that a plant struggling for survival in a harsh environment is also doing its bit to save the planet from the threats of the rapidly changing climate. But that's what Mexico's cactuses are managing to do.
Research published in the journal The Science of Nature shows that desert soils supporting a high density of cactus contain large quantities of stored bio-minerals (minerals produced by living organisms), formed by the action of the plants in extracting carbon dioxide from the atmosphere.
Not only that. Cactuses can also be harvested, processed and turned into a form of leather used to make fashion accessories like purses and wallets.
These two attributes have been turned into a successful business by a Mexican/American company, CACTO. It claims to be the first "carbon negative fashion company in the Americas" − in other words, its activities remove more carbon from the atmosphere than it creates in making and marketing its products.
No Animals Involved
This is a bold claim in an industry struggling with its poor environmental record. According to McKinsey and Co. the worldwide fashion industry emits about the same amount of greenhouse gases as France, Germany and the United Kingdom combined. But CACTO gives Mexico's cactuses special treatment.
CACTO's products are vegan and so allow a growing class of consumers to buy leather objects that are made without any animal products.
The research into the ability of cactus to extract carbon from the atmosphere and store it was carried out on one cactus species, the saguaro (Carnegiea gigantea), which can grow to 40 feet.
It is native to the Sonoran desert in Arizona and the Mexican state of Sonora, and shares with all other cactus varieties the same abilities for dealing with carbon. This has proved a bonus for CACTO because cactuses are the most numerous plants in Mexico.
CACTO's plantations are organic, fed by rainwater, free of herbicides and pesticides, and renewable, and after the ears, or leaves; of the cactus are harvested, the plant grows a replacement in six to eight months. This regeneration allows repeat harvesting. The leaves are then sun-dried to avoid using any electricity. The company's products (available only in green or black) are on sale in more than 100 countries.
CACTO was founded by Jesus Chavez, a climate campaigner, and was designed to have sustainability as a guiding principle at the core of its operation. The entire production cycle is closely monitored by its staff, from the sourcing of materials to production, packaging, distribution and shipping.
Through a partnership with a Swiss non-profit organisation, On a Mission, CACTO says its staff have measured and offset 150% of its CO2 emissions through sustainable reforestation worldwide.
The measurement and offsetting process will take place every six months for the next 10 years. Through several emergent partnerships, the company says it aims to offset at least 1000% of the emissions it generates by the end of 2021.
Engaging Entrepreneurs
Jesus Chavez said: "If we want to succeed in reaching net zero carbon emissions well before 2050 and avoid the worst consequences of climate change, we must all work in concert in whatever capacity we are able to.
"Industries across the board need to benefit from existing technology and offsetting programs to become carbon-negative, and to invest in new research and innovation to reach that goal faster. The decisions we make this decade will determine the fate of humanity for centuries to come. It is up to us now."
He said customers around the world wanted alternatives to materials that increased pollution and to unethical manufacturing processes.
CACTO hopes to inspire a new generation of entrepreneurs to make clear what has been evident to specialists for decades, that decoupling emissions from economic growth is not only feasible, but is the smartest, fastest and most responsible way to grow. Mexico's cactuses bear a heavy responsibility on their ears − or leaves − or branches.

Climate change, activities that contribute to it, and dams pose grave threats to America's rivers, according to American Rivers.
The annual report ranks the county's 10 rivers most endangered by human activity that also have a critical decision point coming in the next year that could change the river's fate.
Four dams are choking the Snake River — earning it the top spot in the report — obstructing salmon and posing an existential threat to Native American tribes in the region who depend on the fish for food, culture and their identities.
Advocates are calling on President Biden to remove the federal dams and revitalize the river and its ecosystem.
Toxic coal ash pollutes the Lower Missouri, which also is experiencing an increase in climate-driven flooding, putting it second on the list, while Iowa's Raccoon River, at number nine, faces threats from industrial agriculture.
Between them are rivers befouled by sewage, polluted or threatened by mining, and otherwise dammed or mismanaged.
"Rivers are among the most degraded ecosystems on the planet, and threats to rivers are threats to human health, safety and survival," American Rivers head Tom Kiernan said.
"If we want a future of clean water and healthy rivers everywhere, for everyone, we must prioritize environmental justice."

Japan will release radioactive wastewater from the failed Fukushima nuclear plant into the Pacific Ocean, the government announced on Tuesday.
The water will be treated before release, and the International Atomic Energy Agency said the country's plans were in keeping with international practice, The New York Times reported. But the plan is opposed by the local fishing community, environmental groups and neighboring countries. Within hours of the announcement, protesters had gathered outside government offices in Tokyo and Fukushima, according to NPR.
"The Japanese government has once again failed the people of Fukushima," Greenpeace Japan Climate and Energy Campaigner Kazue Suzuki said in a statement. "The government has taken the wholly unjustified decision to deliberately contaminate the Pacific Ocean with radioactive wastes."
The dilemma of how to dispose of the water is one ten years in the making. In March 2011, an earthquake and tsunami in northeastern Japan killed more than 19,000 people and caused three of six reactors at the Fukushima Daiichi nuclear power plant to melt down, The New York Times explained. This resulted in the biggest nuclear disaster since Chernobyl, and the cleanup efforts persist more than a decade later.
To keep the damaged reactors from melting down, cool water is flushed through them and then filtered to remove all radioactive material except for tritium. Up until now, the wastewater has been stored on site, but the government says the facility will run out of storage room next year. Water builds up at 170 tons per day, and there are now around 1.25 million tons stored in more than 1,000 tanks.
The government now plans to begin releasing the water into the ocean in two years time, according to a decision approved by cabinet ministers Tuesday. The process is expected to take decades.
"On the premise of strict compliance with regulatory standards that have been established, we select oceanic release," the government said in a statement reported by NPR.
Opposition to the move partly involves a lack of trust around what is actually in the water, as NPR reported. Both the government and Tokyo Electric Power Co., which operates the plant, say that the water only contains tritium, which cannot be separated from hydrogen and is only dangerous to humans in large amounts.
"But it turned out that the water contains more radioactive materials. But they didn't disclose that information before," Friends of the Earth Japan campaigner Ayumi Fukakusa told NPR. "That kind of attitude is not honest to people. They are making distrust by themselves."
In February, for example, a rockfish shipment was stopped when a sample caught near Fukushima tested positive for unsafe levels of cesium.
This incident also illustrates why local fishing communities oppose the release. Fish catches are already only 17.5 percent of what they were before the disaster, and the community worries the release of the water will make it impossible for them to sell what they do catch. They also feel the government went against its promises by deciding to release the water.
"They told us that they wouldn't release the water into the sea without the support of fishermen," fishery cooperative leader Kanji Tachiya told national broadcaster NHK, as CBS News reported. "We can't back this move to break that promise and release the water into the sea unilaterally."
Japan's neighbors also questioned the move. China called it "extremely irresponsible," and South Korea asked for a meeting with the Japanese ambassador in Seoul in response.
The U.S. State Department, however, said that it trusted Japan's judgement.
"In this unique and challenging situation, Japan has weighed the options and effects, has been transparent about its decision, and appears to have adopted an approach in accordance with globally accepted nuclear safety standards," the department said in a statement reported by The New York Times.
But environmentalists argue that the government could have found a way to continue storing waste.
"Rather than using the best available technology to minimize radiation hazards by storing and processing the water over the long term, they have opted for the cheapest option, dumping the water into the Pacific Ocean," Greenpeace's Suzuki said.
