Newly discovered enzyme that turns air into electricity, providing a new clean source of energy

Phys.Org - Australian scientists have discovered an enzyme that converts air into energy. The finding, published today in the journal Nature, reveals that this enzyme uses the low amounts of the hydrogen in the atmosphere to create an electrical current. This finding opens the way to create devices that literally make energy from thin air... Recent work by the team has shown that many bacteria use hydrogen from the atmosphere as an energy source in nutrient-poor environments. "We've known for some time that bacteria can use the trace hydrogen in the air as a source of energy to help them grow and survive, including in Antarctic soils, volcanic craters, and the deep ocean" Professor Chris Greening said. "But we didn't know how they did this, until now."

Exterior carwash care products containing PFAS pollution violations in " in parts per trillion"

Soaps, waxes, polishes...  anytime something is water repellent or water resistant or causes water to bead or has something akin to stain guard in the name. The safety data sheets are unlikely to list "PFAS."  If they do have PFAS, it might be protected under trade secret or be below de minimis amount. This is a growing problem that will catch millions off guard due to lack of understanding and regulatory information on products.

U.S. Averages One Chemical Accident Every Two Days, Analysis Finds

From spills to fires at industrial facilities to the recent train derailment in Ohio, it seems chemical accidents are making the news more and more. But it's not just your imagination — a map by the Coalition to Prevent Chemical Disasters shows that chemical accidents are happening at a rate of one every two days in the U.S. The Chemical Facility Incidents map allows viewers to see chemical-related incidents in their local areas. The coalition noted, "On average, there is a chemical fire, explosion or toxic release every two days in the U.S."

Groundbreaking map shows toxic ‘forever chemicals’ in more than 330 wildlife species

WASHINGTON – Today the Environmental Working Group published an analysis of peer-reviewed data that for the first time shows the global scope of contamination by the "forever chemicals" known as PFAS, which may be harming over 330 wildlife species around the world.

The analysis, based on more than 100 recent peer-reviewed studies, detected over 120 unique PFAS compounds in these animals, not just the legacy forever chemicals PFOA and PFOS. Polluted animals were found on every continent except Antarctica. The absence of PFAS in species in Antarctica is not due to a lack of contamination but instead because of the absence of recent test results in the research we studied.

 "This new analysis shows that when species are tested for PFAS, these chemicals are detected," said David Andrews, Ph.D., senior scientist at EWG. "This is not an exhaustive catalog of all animal studies, but predominantly those published from the past few years.

"PFAS pollution is not just a problem for humans. It's a problem for species across the globe. PFAS are ubiquitous, and this first-of-its-kind map clearly captures the extent to which PFAS have contaminated wildlife around the globe," said Andrews.

The new interactive map plots a great variety of wildlife, including many types of fish, birds, reptiles, frogs and other amphibians, large mammals such as horses and polar bears, and small mammals such as cats. Some are already endangered or threatened.

EPA Proposes Rule to Protect Farmworkers and Pesticide Handlers from Exposures

WASHINGTON (Feb. 16, 2023) – Today, the U.S. Environmental Protection Agency (EPA) announced a proposed rule that would improve and modernize the pesticide Application Exclusion Zone (AEZ) requirements under the 2015 Agricultural Worker Protection Standard (WPS), reaffirming the Agency's commitment to protecting farmworkers, pesticide handlers, their families, and agricultural communities from pesticide exposure during National Pesticide Safety Education Month.

"EPA's top priority is to protect public health and the environment, and today's proposal is a significant step forward to further protect the farmworkers, farmers and pesticide handlers who deliver the fuel, fiber and food that runs America," said EPA Administrator Michael S. Regan. "Farmworker justice is environmental justice, and we're continuing to take action to make sure these communities are protected equally under the law from pesticide exposure."

Application Exclusion Zone

The Worker Protection Standard regulations offer protections to over two million agricultural workers and pesticide handlers who work at over 600,000 agricultural establishments. In 2015, EPA made significant changes to the standard to decrease pesticide exposure among farmworkers and their family members. Less pesticide exposure means a healthier workforce and fewer lost wages, medical bills and absences from work.

Among the changes, the revised standard included a new provision requiring agricultural employers to keep workers and all other individuals out of an area called the AEZ during outdoor pesticide applications. The AEZ is the area surrounding an ongoing pesticide application that people must not enter to avoid exposure. An AEZ moves with the equipment during applications to protect farmworkers and bystanders that could be contacted by pesticides.

In 2020, the previous administration published a rule specific to the AEZ requirements, limiting the applicability of the protections to the agricultural employer's property and shrinking the AEZ size from 100 feet to 25 feet for some ground-based spray applications. Prior to the effective date of the 2020 AEZ Rule, petitions were filed in the U.S. District Court for the Southern District of New York (SDNY) and in the U.S. Second Circuit Court of Appeals challenging the 2020 Rule (now consolidated as case number 20 Civ. 10642). The SDNY issued an order granting the petitioners' request for a temporary restraining order. As a result, the 2020 AEZ Rule has not gone into effect, and the AEZ provisions in the 2015 WPS remain in effect.

Through its review, EPA has determined that the provisions in the 2020 AEZ Rule that weakened protections for farmworkers and nearby communities from pesticide exposure should be rescinded to protect the health of farmworkers, their families, and nearby communities.

DOE - Announces $74 Million to Advance Enhanced Geothermal Systems

WASHINGTON, D.C. — The U.S. Department of Energy (DOE) today announced a funding opportunity of up to $74 million for up to seven pilot projects that will test the efficacy and scalability of enhanced geothermal systems (EGS). Directed by the landmark Bipartisan Infrastructure Law (BIL), the pilot projects will use innovative technology and a variety of development techniques to capture the Earth's abundant heat resources in diverse geologic settings. Through this investment, DOE hopes the research and development from the findings would demonstrate the growth and ultimate potential for geothermal energy to provide reliable, around-the-clock electricity to tens of millions of homes across the country. This is DOE's first funding opportunity for geothermal energy since the launch of the Enhanced Geothermal Shot^TM, part of DOE's Energy EarthShots Initiative, which seeks to cut the cost of geothermal energy 90% by 2035.

"Advances in enhanced geothermal systems will help introduce geothermal energy in regions where, until recently, the use of this renewable power source was thought to be impossible," said U.S. Secretary of Energy Jennifer M. Granholm. "These pilot demonstrations will help us realize the enormous potential of the heat beneath our feet to deliver clean, renewable energy to millions of Americans."

Geothermal energy currently generates about 3.7 gigawatts of electricity in the United States, but a new analysis shows it could provide 90 gigawatts of firm, flexible power to the U.S. grid by 2050, as well as heating and cooling solutions nationwide. This substantial geothermal energy potential is, however, largely inaccessible with conventional geothermal technologies. The use of geothermal energy for electricity requires three elements: heat, fluid, and a permeable section of the Earth's crust. While heat exists everywhere underground, many locations lack adequate water and/or permeability. EGS employ human-made underground reservoirs to enable the fluid flow necessary to draw geothermal energy to the surface, where it can be captured to power homes across the country. Achieving this goal would make geothermal energy a clean, cost-effective option across the country, while spurring progress toward President Biden's goals of 100% carbon-pollution-free electricity by 2035 and net-zero emissions by 2050.

Latest ‘Fatal Facts’ explores risk of hydrogen sulfide poisoning

Safety+Health  — OSHA is warning employers and workers about the risk of hydrogen sulfide poisoning in the agency's latest edition of Fatal Facts.

The resource details the Chemical Safety Board's investigation into the October 2019 hydrogen sulfide release at the Aghorn Operating Waterflood Station in Odessa, TX. During the incident, a worker responded to an alarm from a water pump, which was part of the process of extracting natural gas and crude oil. The worker was alone in the pump house when he tried to close process valves to isolate the pump.

"Either before the worker's arrival or during his work, the pump unexpectedly energized, releasing water containing H₂S gas into the pump house," the newsletter states. "The H₂S concentration reached fatal levels, killing the worker."

OSHA offers likely causes for the incident and lists steps to prevent future incidents. Recommendations include:

• Mandate the use of personal hydrogen sulfide detection devices as an integral part of every employee or visitor personal protective equipment kit before entering the vicinity of the facility.
• Ensure detector use is in accordance with manufacturer specifications.
• Commission an independent and comprehensive analysis of each facility's ventilation design and mitigation systems to ensure workers are protected from exposure to toxic gas.
• Ensure the hydrogen sulfide detection and alarm systems are properly maintained and configured, and develop site-specific detection and alarm programs and associated procedures based on manufacturer specifications, current codes, standards and industry good practice guidance.

Stars Are Disappearing From Sight at an Astonishing Rate - 80% of people in the United States can’t even see the Milky Way swirl of our galaxy anymore.

For decades, light pollution has been vexing sky lovers and scientists alike. Not to mention the impact light pollution has on the natural world, from affecting human health and birds' nighttime navigation to disorienting baby sea turtles and disrupting the mating patterns of fireflies. And lest we forget: the lighting that causes light pollution wastes important resources.

Yet despite this knowledge, light pollution has been challenging to document, especially on a global scale. But now, a new study shows that light pollution is rapidly worsening. 

The analysis comes from Globe at Night, a citizen science program run by the National Science Foundation's NOIRLab. The study concludes that stars are disappearing from human sight at a stunning rate. By relying on the observations of sky-gazers across the globe, the researchers found that light pollution has had much more of an impact than indicated by satellite measurements. 

From the glimmering swath of our home galaxy, the Milky Way, to a multitude of constellations, the human eye should be able to see thousands of stars on a clear, dark night. Yet thanks to light pollution, 80% of people in the United States can't even see the Milky Way swirl of our galaxy anymore. 

​A Mass Extinction Is Taking Place in the Human Gut

"Trillions of bacteria, fungi, and other microbes live in the digestive tract. Many of them are beneficial to human health—influencing our metabolism and immune system, for example. But their diversity is under threat from industrialization, urbanization, and environmental changes."

As more people move to cities, they adopt new eating habits and are exposed to a different environment. Pastoralists in Ethiopia are also starting to buy more foods such as rice and pasta. This could change the composition of their microbiome and push the specialized bacteria living in their guts to extinction, according to public health researcher Abdifatah Muhummed

Japan estimates Fukushima water release to start in 'spring or summer'

(Reuters) - The Japanese government gave an estimation for when the water from the destroyed Fukushima nuclear power plant will be released into the sea, saying at a cabinet meeting held on Friday it could happen sometime "around this spring or summer."

In April 2021, the government approved the release of more than 1 million tonnes of irradiated water from the site after treatment into the ocean. It said the release would happen "in about two years" at the time.

Japan's foreign ministry said in July that regulators deemed it safe to release the water, which would be filtered to remove most isotopes but would still contain traces of tritium, an isotope of hydrogen hard to separate from water.

​DNR Now Accepting Brownfield Assessment Grant Applications

MADISON, Wis. – The Wisconsin Department of Natural Resources (DNR) is now accepting applications for the Wisconsin Assessment Monies (WAM) brownfield assessment grant program.

Brownfields are properties where the expansion, redevelopment or reuse of which may be complicated by the presence or potential presence of contamination. Brownfields vary in size, location, age and past use; they can be anything from a 500-acre former automobile assembly plant to a small, abandoned gas station.

The WAM program provides services and funding to investigate brownfield sites where potential or known contamination is impeding redevelopment. Since 2010, the U.S. Environmental Protection Agency (EPA) has awarded the DNR and its partners $5.3 million in brownfield assessment grant funding. The DNR uses the money to help local governments and others in investigating brownfield properties throughout the state.

"Conducting an environmental assessment is the first step to bring a brownfields site closer to revitalization," said Jodie Peotter, DNR Brownfields, Outreach and Policy Section Chief.

Factors that may be considered in award selection are projects in rural or disadvantaged communities, community involvement and support, sites that are impediments to large-scale redevelopment projects, positive community outcomes (e.g., economic, health, livability), financial need and projects with redevelopment plans consistent with local redevelopment objectives.

Applicants may apply for up to approximately $54,000 in contractor services, where the DNR contracts directly with and oversees qualified environmental professionals to complete the assessment work. Alternatively, subgrants of up to $75,000 are available to communities who prefer to select a qualified consultant and oversee the assessment work.

3M will stop making hazardous ‘forever chemicals’ starting in 2025

CNN  —  3M, the conglomerate behind Post-It notes and Scotch tape, will stop making controversial per- and polyfluoroalkyl substances (PFAS) by the end of 2025.

The chemicals, commonly known as "forever chemicals," are found in hundreds of household items and used to make coatings and products that can repel water, grease, heat and oil. The most recent science suggests that these chemicals are much more hazardous to human health than scientists had initially thought and probably more dangerous at levels thousands of times lower than previously believed.

In a statement Tuesday, 3M said its decision is "based on careful consideration and a thorough evaluation of the evolving external landscape," acknowledging that regulations are cracking down on the chemicals.

For example, the Environmental Protection Agency announced a proposal earlier this year to label "forever chemicals" as hazardous substances. California also announced a lawsuit recently to recoup the clean-up costs from PFAS.

"While PFAS can be safely made and used, we also see an opportunity to lead in a rapidly evolving external regulatory and business landscape to make the greatest impact for those we serve," said 3M CEO Mike Roman in a statement. "This action is another example of how we are positioning 3M for continued sustainable growth by optimizing our portfolio, innovating for our customers, and delivering long-term value for our shareholders."

The company expects to take a financial hit of about $1.3 billion to $2.3 billion over the next few years because of the PFAS discontinuation. Yet 3M (MMM) said PFAS represents a "small portion" of its revenue.

FTC Issues Revised "Green Guides" Will Help Marketers Avoid Making Misleading Environmental Claims

The Federal Trade Commission issued revised "Green Guides" that are designed to help marketers ensure that the claims they make about the environmental attributes of their products are truthful and non-deceptive.

The revisions to the FTC's Green Guides reflect a wide range of public input, including hundreds of consumer and industry comments on previously proposed revisions. They include updates to the existing Guides, as well as new sections on the use of carbon offsets, "green" certifications and seals, and renewable energy and renewable materials claims.

"The introduction of environmentally friendly products into the marketplace is a win for consumers who want to purchase greener products and producers who want to sell them," said FTC Chairman Jon Leibowitz. "But this win-win can only occur if marketers' claims are truthful and substantiated. The FTC's changes to the Green Guides will level the playing field for honest business people and it is one reason why we had such broad support."

In revising the Green Guides, the FTC modified and clarified sections of the previous Guides and provided new guidance on environmental claims that were not common when the Guides were last reviewed.

Revisions to Previous Guidance. Among other modifications, the Guides caution marketers not to make broad, unqualified claims that a product is "environmentally friendly" or "eco-friendly" because the FTC's consumer perception study confirms that such claims are likely to suggest that the product has specific and far-reaching environmental benefits. Very few products, if any, have all the attributes consumers seem to perceive from such claims, making these claims nearly impossible to substantiate.

The Guides also:

• advise marketers not to make an unqualified degradable claim for a solid waste product unless they can prove that the entire product or package will completely break down and return to nature within one year after customary disposal;

• caution that items destined for landfills, incinerators, or recycling facilities will not degrade within a year, so marketers should not make unqualified degradable claims for these items; and

• clarify guidance on compostable, ozone, recyclable, recycled content, and source reduction claims.

New Sections. The Guides contain new sections on: 1) certifications and seals of approval; 2) carbon offsets, 3) free-of claims, 4) non-toxic claims, 5) made with renewable energy claims, and 6) made with renewable materials claims.

A single scratch on a non-stick coated pan can release approximately 9,100 PFAS plastic particles.

A new study, published in the Science of The Total Environment (PMID: 36030853) found that a single scratch on a non-stick coated pan can release approximately 9,100 plastic particles.

"Plastic" in this paper refers to PFAS chemicals that are polymers - not the kind of plastic used in water bottles, etc.

Many (but not all) chemicals in the PFAS family are classified as polymers. Polymer simply means "many segments" - they are molecules that are long chains made up of many segments.

This paper has found that non-stick-coated cookware can release thousands to millions of these micro and nano-plastic polymers. They are releasing PFAS particles when used, and these particles are ending up in our food. This testing was done mimicking around 30 seconds of cooking on both new and old/used cookware with different types of utensils.

Study authors write: "It is expected that the true amount of the released microplastics and nanoplastics from the actual cooking process is significantly higher, even with variations"

NASA Scientists Join White House Cancer Initiative

NASA - "Cancer is a leading cause of death among Americans as well as a long-term risk for astronauts due to space radiation exposure. Scientists at NASA have been studying cancer for decades, focusing on understanding risks to astronauts," said NASA Administrator Bill Nelson. "Through this initiative, NASA will work with agencies and researchers across the government to help end cancer as we know it. This endeavor represents NASA's ambition to propel humanity forward – for science, for health, and for hope." 

NASA's space radiation team is comprised of 25 people across the agency, universities, industries, and government facilities. Representatives meet periodically with the Presidential Cancer Cabinet, which includes Administrator Nelson, to discuss the status of their research, and brainstorm ideas to further progress and interagency collaboration.

"The White House has requested all hands on deck to improve the outcome of cancer diagnoses," said Vanessa Wyche, director of NASA's Johnson Space Center in Houston. "We are honored to have employees from the Space Radiation Element not only work to protect our astronauts, but also work to protect our nation through the Cancer Moonshot Initiative."

For instance, scientists are seeking to develop and test new screening technologies for specific cancers as only a handful of cancers currently have well-vetted, early-detection protocols. They strive to incorporate these new detection methods into the astronaut health surveillance program, which could help spot certain cancers earlier and make these measures more widely available.

"We want to know: What are those cancers' early 'tells'? And how feasible is it to screen for those tells?" explained Robin Elgart, Space Radiation Element lead scientist at Johnson. "If we could find these early-detection technologies and implement them into the astronaut health surveillance program, collaborations through the Cancer Moonshot could pave the way for broader use and acceptance of these new detection methods." 

"NASA support could even help the new technologies to come to market," added Brock Sishc, Space Radiation Element cancer discipline lead at Johnson. "Then we can help not only our astronauts, but also potential cancer patients on Earth."

Scientists are also working to identify medicines and dietary supplements that could help reduce the risk of cancer from radiation exposure. Searching for such compounds requires scrutinizing large groups of people over long durations – something NASA's small set of astronauts can't provide. Using connections forged through the Cancer Moonshot to access and process vast data sets involved with modern drug screening may help. Finding patterns in these data sets could reveal new insights.

In addition, NASA seeks to harness cutting-edge technologies to develop personalized cancer risk assessments from radiation exposure. The research, still in its early stages, involves using small devices called tissue chips, which help scientists model human systems.

U.S. Department Of Energy Announces $43 Million to Support the Clean Energy Transition in Communities Across the Country

Research Projects Across 19 States, the District of Columbia, and Puerto Rico Will Help Communities Improve Energy Planning, Increase Grid Resilience, and Restore Power After Disasters

The U.S. Department of Energy (DOE) today announced $43 million for 23 projects to help communities plan their transition to a clean energy future and improve grid reliability and security. Twenty research projects will focus on increasing communities' resilience to disruptions from extreme weather and other disasters, and three will focus on building tools to help communities better evaluate and benefit from local energy resources. Researchers will develop and share planning methodologies, tools, technologies, and best practices that can be replicated in communities across the country as they work to install clean energy and strengthen grid infrastructure. Today's project announcements will help communities secure their energy future and support President Biden's goals to decarbonize the electricity sector by 2035 and achieve a net-zero economy by 2050.

"Knowledge is power, especially when it comes to giving local communities the tools to understand and make informed decisions about their own energy supply and needs," said U.S. Secretary of Energy Jennifer M. Granholm. "These critical projects will help deliver reliable, affordable energy to every pocket of America—strengthening the safety and resiliency of communities across the nation and improving the quality of life for Americans everywhere."

Communities across the nation have faced increased disruptions in power caused by extreme weather events due to climate change. According to NOAA's National Centers for Environmental Information, the U.S. has sustained 15 climate disaster events in 2022 with losses exceeding $1 billion each. Overall, these events have cost $30 billion and had significant economic effects on the areas impacted. Power outages can have disastrous effects, shutting down critical services such as water, energy, communications, transportation, and other types of infrastructure.

The Renewables Advancing Community Energy Resilience (RACER) funding program seeks to enable communities to utilize solar and solar-plus-storage solutions to prevent disruptions in power caused by extreme weather and other events, and to rapidly restore electricity if the power goes down. The 20 projects selected under RACER will advance innovative approaches to community energy planning and develop and demonstrate resilient clean energy technologies. These projects span over 30 diverse communities from California to Puerto Rico, and include partners from local and state governments, national labs, universities, and nonprofit organizations.

​ EPA Issues Final List of Contaminants for Potential Regulatory Consideration in Drinking Water, Significantly Increases PFAS Chemicals for Review

WASHINGTON (November 2, 2022) – Today, the U.S. Environmental Protection Agency (EPA) published the Final Fifth Drinking Water Contaminant Candidate List (CCL 5), which will serve as the basis for EPA's regulatory considerations over the next five-year cycle under the Safe Drinking Water Act. This update includes a substantial expansion of per- and polyfluoroalkyl substances (PFAS), an important first step towards identifying additional PFAS that may require regulation under the Safe Drinking Water Act.

"Following public engagement and robust scientific review, the final contaminant candidate list is the latest milestone in our regulatory efforts to ensure safe, clean drinking water for all communities," said EPA Assistant Administrator for Water Radhika Fox. "As EPA takes action to protect public health and the environment from PFAS, including proposing the first nationwide drinking water standards later this year, today's final CCL 5 looks further forward to consider additional protective steps for these forever chemicals."

A year ago, EPA published the PFAS Strategic Roadmap, outlining an Agency-wide approach to addressing PFAS in the environment. Today's announcement strengthens EPA's commitment to protect public health from impacts of PFAS and support the Agency's decision-making for potential future regulations of PFAS.

In addition to a group of PFAS, the Final CCL 5 includes 66 individually listed chemicals, two additional chemical groups (cyanotoxins and disinfection byproducts (DBPs)), and 12 microbes.

In developing the Final CCL 5, EPA requested public nominations, providing an opportunity for people to make recommendations to the Agency about specific contaminants of concern that may disproportionally affect their local community. EPA further enhanced the CCL process based on comments received on this CCL and previous CCLs, including by prioritizing data most relevant to drinking water exposure, improving considerations of sensitive populations including children, and considering the recommendations included in the Review of the EPA's Draft Fifth Contaminant Candidate List (CCL 5) report from the Science Advisory Board. These improvements resulted in a Final CCL 5 that can better inform prioritization of contaminants for potential regulatory actions and/or research efforts.

EPA determined that Pigment Violet 29 (PV29) presents unreasonable risk to human health.

The agency assessed the impact of PV29 on workers, the general population, and consumers. EPA found unreasonable risk to workers and occupational non-users from manufacture, processing, industrial/commercial use in paints and coatings and merchant ink, and disposal. This is based on the severity of the health effects (specifically lung toxicity effects known as alveolar hyperplasia or an adverse increase in the number of cells in the lungs where oxygen transfer occurs) from long-term inhalation exposure. These risks drive the whole chemical determination of unreasonable risk to human health.

EPA Advances Rule to Designate PFOA, PFOS as CERCLA “Hazardous Substances”

Michael Best & Friedrich: After months of speculation as to timing, last week the U.S. Environmental Protection Agency (EPA) Administrator Regan advanced the Agency's proposed rule for the "Designation of Perfluorooctanoic Acid (PFOA) and Perfluorooctanesulfonic Acid (PFOS) as CERCLA Hazardous Substances." The official version of the proposed rule has not yet been published in the Federal Register. When that occurs (expected within a few days), the 60-day public comment period will be triggered.  The proposed rule's release is on the heels of the Office of Management & Budget's (OMB) announcement that it designated the rulemaking as an economically significant action – a designation for measures expected to cost more than $100 million. The proposed rule attempts to address OMB's announcement by releasing its economic analysis (EA) of the potential costs, benefits and impacts associated with this action. When the proposed rulemaking is officially published, EPA's Economic Assessment of the Potential Costs and Other Impacts of the Proposed Rulemaking to Designated Perfluorooctanoic Acid and Perfluorooctanesulfonic Acid as Hazardous Substances will be available for review and comment in EPA's docket.

EPA designates five economy-wide categories of entities potentially affected by the proposed rule:

• PFOA and/or PFOS manufacturers (including importers and importers of articles)
• PFOA and/or PFOS processors
• Manufacturers of products containing PFOA and/or PFOS;
• Downstream product manufacturers and users of PFOA and/or PFOS products; and
• Waste management and wastewater treatment facilities.

Given the widespread historic use of PFOA and PFOS for fire suppression and in the manufacture of consumer products and packaging, the proposed rule has wide-reaching impact and EPA's "categories" confirms the same.

Designation as Hazardous Substances
There are two ways that a substance may defined as a "hazardous" substance under CERCLA. The first is automatic when the substance is identified as hazardous or toxic pursuant to other specified federal environmental statutes (such as the Clean Air Act, Clean Water Act, Resource Conservation and Recovery Act, etc.). The second is where the substance is designated as hazardous pursuant to CERLCA Section 102.  EPA's rulemaking is pursuant to CERCLA Section 102(a) which allows EPA to promulgate regulations designating as hazardous a substance "which, when released into the environment may present substantial danger to the public health or welfare or the environment." 42 U.S.C. § 9602(a).

Notably, EPA has never exercised its authority pursuant to Section 102(a) before so it has not previously issued an interpretation of the standard for designating a hazardous substance under CERCLA. The proposed rule conducts such an analysis to defend its rulemaking. Given that EPA has not used its authority in this manner before, expect this to be an area of focus for future legal challenges.

"Direct Impact" of the Proposed Rulemaking
EPA identifies three direct effects of the proposed rule. First, any person in charge of a vessel or facility must report releases of PFOA and PFOS of one (1) pound or more within a 24-hour period. EPA acknowledges this will apply to very few facilities/vessels because the Agency's estimate is that this will cause an increased cost of $561/release and an estimated annual cost of $370,000.  The second direct effect is that Federal agencies would be required to meet all of the property transfer requirements of CERCLA 120(h) when selling or transferring Federally-owned real property. This would require providing notice when any hazardous substance was stored for one year or more, known to have been released or disposed of, and providing a covenant warranting that all remedial action necessary to protection human health and the environment with respect to hazardous substances has occurred before the transfer (or will be conducted by the Federal government after the transfer).  With PFOA and PFOS included as hazardous substances, Federal agencies would need to consider those compounds in any property transfer notice.  The third direct effect is that upon designation as a hazardous substance, the Department of Transportation (DOT) would be required to list and regulate PFOA and PFOS as hazardous materials under the Hazardous Materials Transportation Act (HMTA).

"Indirect Impacts" of the Proposed Rulemaking
EPA seemingly acknowledges that the real "action" of this proposed rulemaking is what the agency considers "indirect, downstream effects" of the designation.  These "indirect effects" include:

• EPA and other agencies exercising delegated CERLCA authority to respond to PFOA and PFOS releases and threatened releases without making the imminent and substantial endangerment finding that is required for responses now.
• EPA and delegated agencies could require potentially responsible parties ("PRPs") to address PFOA and PFOS releases that pose an imminent and substantial danger to public health or welfare or the environment.
• EPA and delegated agencies could recover PFOA and PFOS cleanup costs from PRPs, "to facilitate having polluters and other PRPs, rather than taxpayers, pay for these cleanups."
• Private parties that conduct cleanups that are consistent with the National Oil and Hazardous Substances Contingency Plan (NCP) could also recover PFOA and PFOS cleanup costs from PRPs.

EPA asserts that the CERCLA designation would "likely increase the pace at which cleanups occur because it will allow the Federal government to require responsible private parties to address releases of PFOS and PFOA at sites without other ongoing cleanup activities, and allow the government and private parties to seek to recover cleanup costs from PRPs assuming relevant statutory criteria are met."

EPA considers CERCLA response actions, including the investigation of hazardous substance releases and determining if removal or remedial action is necessary, to be "contingent, discretionary, and site-specific actions" as compared to the "only automatic, private party obligation that flows from designation as a CERCLA hazardous substance" which is the obligation to report releases of PFOA and PFOS.  EPA uses this apparent distinction to assert that this designation "does not create new costs, but rather allows costs to be shifted from the taxpayer to parties responsible for pollution under CERCLA" and that "[e]ven in those circumstances, where the government is able to transfer costs, a private party's ability to pay response costs is taken into account under the statute and in EPA's implementation" of CERCLA.

Forever Chemicals No More? PFAS Are Destroyed With New Technique

The harmful molecules are everywhere, but chemists have made progress in developing a method to break them down.

Dr. Trang and Dr. Dichtel teamed up with other chemists at U.C.L.A. and in China to figure out what was happening. The sodium hydroxide hastens the destruction of the PFAS molecules by eagerly bonding with the fragments as they fall apart. The fluorine atoms lose their link to the carbon atoms, becoming harmless.

"Once you give it a chance, this thing will unzip," Dr. Dichtel said.

Dr. Strathmann, who was not involved in the research, said that the new study was important because it was based on chemistry profoundly different from other methods that were being studied. "We're going to need some creative solutions," he said.

Wisconsin PFAS Action Council Releases PFAS Action Plan Progress Report

The Wisconsin Department of Natural Resources (DNR) today announced the Wisconsin PFAS Action Council (WisPAC) released its PFAS Action Plan Progress Report. The Progress Report outlines steps taken by state agencies to address PFAS contamination since December 2020, when the Wisconsin PFAS Action Plan was released.

The Wisconsin PFAS Action Plan includes 25 recommended action items categorized into eight themes: standard setting, sampling, pollution prevention, education and communication, research and knowledge, phase-out, future investments and historic discharges.

"The progress we've seen with addressing PFAS as a state is a reflection of the coordination and collaboration that grew out of WisPAC and the PFAS Action Plan," said DNR Secretary Preston D. Cole. "I am proud of the continued work by WisPAC, with DNR at the helm, in partnership with communities and stakeholders working together toward solutions that will protect the public and support our businesses."

Progress report highlights include:

• Investing $1 million to collect more than 25,000 gallons of PFAS-containing firefighting foam waste from across more than 60 counties in Wisconsin.
• Sampling more than 125 municipal drinking water systems, 100 waste water treatment plants and hundreds of private drinking water wells.
• Establishing the Office of Environmental Justice.
• Initiating legal action against 18 major chemical companies.

WisPAC member agencies will continue working on the Action Plan and expect additional community resources to be deployed this year. In addition to launching an interactive PFAS mapping tool, work continues with stakeholders to implement standards for certain PFAS in drinking water and surface water.

The PFAS Action Plan was developed by WisPAC, a group of nearly 20 state agencies and the University of Wisconsin, to address environmental and public health concerns that are or may be posed by per- and polyfluoroalkyl substances (PFAS) in Wisconsin. The plan was created in response to Governor Evers' Executive Order #40, directing Dept. of Natural Resources to lead a group of state agencies in building a blueprint for how Wisconsin can address the use of and contamination from these "forever chemicals."

With DNR leading the way, WisPAC has partnered with Wisconsin's local governments, businesses and communities in developing and implementing the PFAS Action Plan. Recommended actions in the plan include items identified through input from the public, state agencies and a citizen and local government advisory group. Each recommendation contains an overview of what would be required to bring it to fruition, including budgetary, legislative and staffing needs.

Dangerous Cleaning Products Prompt FDA Warning

This summer, the FDA issued a warning to consumers outlining the risk of using certain UV disinfecting light wands. Recent testing found some of the lights produce dangerous levels of UV-C radiation and pose the risk of eye and skin damage to people in the vicinity of the light.

The damage can occur with just a few seconds of exposure, officials say. Symptoms include a burn-like skin reaction and photokeratitis, a painful eye condition that can lead to a feeling of sand in the eyes.

Safety investigators on the case said the following list includes products not properly equipped to protect people from the radiation (but noted that the list is not exhaustive, and other products on the market may be unsafe, as well). In some cases, UV-C radiation levels were 3,000 times more than the exposure limit recommended by the International Commission on Non-Ionizing Radiation Protection.

Cleaning Alternatives

Home cleaning products are generally not tested for long-term impact on public health. In fact, it's difficult to even know all of the ingredients in cleaners, since they only have to account for active ingredients.

It may come as no surprise, then, that people who clean for a profession can experience lung damage equivalent to smoking 20 cigarettes a day for 10 to 20 years.

Knowing the chemical damage that can occur from chemical cleaning products, it's no wonder people are looking for alternatives like UV disinfectants. The problem is we don't have strong laws to make sure they are safe before going on sale to the general public.

You can even take a look at its database, focusing in on how products rank in its disinfectant category.

Here are a few cleaning tips to remember:

• While vinegar is a group cleaning product, it is generally not the greatest disinfectant.
• A 2014 study found that it can kill bacteria that causes tuberculosis, however, it took 30 minutes of contact time, which isn't always practical.
• When you do clean with vinegar, use a 1:1 ratio of what vinegar to water for cleaning stovetops, floors and other surfaces. (Always test an inconspicuous spot. Vinegar doesn't play well with certain surfaces, like stone, waxed wood, aluminum and cast iron, according to NSF.)

Conclusion

• UV light disinfection wands are gaining popularity, although the FDA found many to be unsafe.
• FDA testing found certain UV wands emitted UV-C radiation at levels 3,000 times above the recommended safe level.
• Even just a few seconds of exposure at these levels can cause skin and eye damage, the FDA noted.
• Choose safer cleaning and disinfection methods, like scrubbing with soap and water and using unscented rubbing alcohol (minimum 60% alcohol) to kill germs.

• Organohalogen and organophosphate flame retardants listed in RCW 70A.430 in recreational polyurethane covered wall padding
• PFAS in outdoor leather and textile furniture and furnishings
• Bisphenols in food can linings

What changed between the draft and final report

We made a number of changes to integrate feedback from our stakeholders and communities. Read how we incorporated feedback in our comment overview. Three regulatory determinations changed between draft and final:

• We changed our determination to no action on polychlorinated biphenyls (PCBs) in paints or printing inks. We believe federal Toxic Substances Control Act (TSCA) regulations preempt us.
• We changed our determination from a restriction on PFAS in leather and textile furniture and furnishings intended for outdoor use to a reporting requirement.
• We changed our determination from a restriction on flame retardants in electric and electronic enclosures intended for outdoor use to a reporting requirement. We also further clarified which electric and electronic products are in scope.

If interested, you can view comments from other stakeholders on the draft report. To hear a summary of the results from our public comment survey, watch our video covering the highlights (also available in Spanish).

Help counseling patients on PFAS

Healthcare providers need to know how to counsel patients about PFAS, known as "forever chemicals." Perfluoro alkyl substances (PFAS) have been found contaminating over 2,500 communities in the US, and 97% of Americans have PFAS in their blood. On July 28, the National Academies of Science, Engineering, and Medicine released a report recommending that healthcare providers order PFAS blood levels on their exposed patients.

Doctors, nurses and other health professionals need to know who is exposed, how to interpret blood PFAS results, and what to tell their patients. We have developed two short videos (2 minutes each) for healthcare providers that introduces them to PFAS and directs them to a CME webinar on PFAS hosted at the University of Cincinnati. We are asking you to help us disseminate these videos to your providers and other stakeholders, on your social media, or in your newsletter.

Here are the links to the videos:

EPA Issues Draft Revisions to its Risk Determination for the 1-Bromopropane (1-BP) Risk Evaluation Issued Under the Toxic Substance Control Act

On July 20, 2022, EPA published a draft revision to its risk determination for 1-bromopropane, also referred to as "1-BP." EPA proposed revisions to supersede the conditions of use previously issued in the 2020 1-BP evaluation. Due to recent policy changes, EPA is replacing its condition of use-specific unreasonable risk determinations with a determination of unreasonable risk for 1-BP as a whole chemical substance driven by certain condition of uses.

As part of the revision, EPA is removing the assumption of personal protective equipment use by workers, which means that 23 out of 25 conditions of use evaluated would drive the determination that 1-BP presents an unreasonable risk of injury to human health under its conditions of use. Two out of 25 conditions of use would not drive the unreasonable risk: commercial and consumer use of 1-BP in insulation for building and construction materials, and distribution in commerce.

Comments are due on August 19, 2022.

​The world's largest vertical farm ready to produce more than 2 million pounds of leafy greens annually.

The world's largest vertical farm using 95% less water and is ready to produce more than 2 million pounds of leafy greens annually.

Bustanica was built by Crop One Holdings in collaboration with Emirates Flight Catering. It recently opened its doors in Dubai, the United Arab Emirates, near Al Maktoum International Airport at Dubai World Central. The facility is as big as 330,000-square-foot and spans over 175 yards.
95% less water

The crops produced in the facility will turn out clean and not require pre-washing as they will grow without pesticides, herbicides, or chemicals. The facility itself employs 95 percent less water, unlike traditional farms, and will produce three tons of output per day while wielding machine learning, artificial intelligence, and data analytics.

The facility utilizes a closed-loop system that circulates water through plants to use water efficiently. Water vaporizes during the watering process and is recycled into the system, which saves 250m liters of water every year compared to traditional outdoor farming producing the same output.

7 Cryptomining Companies Use Nearly as Much Energy as All Homes in Houston, Congressional Investigation Finds

A new congressional investigation, led by Sen. Elizabeth Warren (D-Mass), has found that seven of the top Bitcoin mining companies will use about as much energy as all the homes in Houston (nearly 1 million homes), the fourth most populous city in the U.S.

A group of Democratic Senators, including Warren and Sheldon Whitehouse (D-R.I.), Edward J. Markey (D-Mass.) and Jeff Merkley (D-Ore.), and Representatives Jared Huffman (D-Calif.) and Rashida Tlaib (D-Mich.) are calling on the Environmental Protection Agency (EPA) and Department of Energy (DOE) for more regulations on the cryptomining industry.

"The results of our investigation … are disturbing … revealing that cryptominers are large energy users that account for a significant – and rapidly growing – amount of carbon emissions," the lawmakers wrote in a letter to EPA and DOE. "Our investigation suggests that the overall U.S. cryptomining industry is likely to be problematic for energy and emissions. But little is known about the full scope of cryptomining activity. Given these concerns, it is imperative that your agencies work together to address the lack of information about cryptomining's energy use and environmental impacts, and use all available authorities at your disposal…  to require reporting of energy use and emissions from cryptominers."

Maine Act To Stop Perfluoroalkyl and Polyfluoroalkyl Substances Pollution

In July 2021, Public Law c. 477, An Act To Stop Perfluoroalkyl and Polyfluoroalkyl Substances Pollution (LD 1503, 130th Legislature) was enacted by the Maine Legislature. This new law requires manufacturers of products with intentionally added PFAS to report the intentionally added presence of PFAS in those products to the Department beginning January 1, 2023. The law also prohibits the sale of carpets or rugs, as well as the sale of fabric treatments, that contain intentionally added PFAS beginning on January 1, 2023. Effective January 1, 2030, any product containing intentionally added PFAS may not be sold in Maine unless the use of PFAS in the product is specifically designated as a currently unavoidable use by the Department.

 

To implement the product notification requirements the Department is working with the Interstate Chemicals Clearinghouse to develop an online reporting database similar to those already in use by other states. The Department is also in the process of developing a rule to clarify the upcoming reporting requirements. During the rule development process there will be an opportunity for stakeholder input on the implementation of the program. If you are interested, please sign up to receive notification of Department rulemaking and opportunity to comment notices on our website.

CDC study finds ‘Disturbing’: weedkiller ingredient tied to cancer found in 80% of US urine samples

theguardian: CDC study finds glyphosate, controversial ingredient found in weedkillers including popular Roundup brand, present in samples

More than 80% of urine samples drawn from children and adults in a US health study contained a weedkilling chemical linked to cancer, a finding scientists have called "disturbing" and "concerning".

The report by a unit of the Centers for Disease Control and Prevention (CDC) found that out of 2,310 urine samples, taken from a group of Americans intended to be representative of the US population, 1,885 were laced with detectable traces of glyphosate. This is the active ingredient in herbicides sold around the world, including the widely used Roundup brand. Almost a third of the participants were children ranging from six to 18.
A bumblebee covered in pollen

Academics and private researchers have been noting high levels of the herbicide glyphosate in analyses of human urine samples for years. But the CDC has only recently started examining the extent of human exposure to glyphosate in the US, and its work comes at a time of mounting concerns and controversy over how pesticides in food and water impact human and environmental health.

"I expect that the realization that most of us have glyphosate in our urine will be disturbing to many people," said Lianne Sheppard, professor at the University of Washington's department of environmental and occupational health sciences. Thanks to the new research, "we know that a large fraction of the population has it in urine. Many people will be thinking about whether that includes them."

Revealed: US water likely contains more cancer causing ‘forever chemicals’ than EPA tests show

Guardian analysis of water samples taken in nine US locations shows test agency uses is likely missing significant levels of PFAS pollutants

A Guardian analysis of water samples from around the United States shows that the type of water testing relied on by the US Environmental Protection Agency (EPA) is so limited in scope that it is probably missing significant levels of PFAS pollutants.

The undercount leaves regulators with an incomplete picture of the extent of PFAS contamination and reveals how millions of people may be facing an unknown health risk in their drinking water.

The analysis checked water samples from PFAS hot spots around the country with two types of tests: an EPA-developed method that detects 30 types of the approximately 9,000 PFAS compounds, and another that checks for a marker of all PFAS.

The Guardian found that seven of the nine samples collected showed higher levels of PFAS in water using the test that identifies markers for PFAS, than levels found when the water was tested using the EPA method – and at concentrations as much as 24 times greater.

"The EPA is doing the bare minimum it can and that's putting people's health at risk," said Kyla Bennett, policy director at the advocacy group Public Employees for Environmental Responsibility
Ties to cancer

PFAS are a class of chemicals used since the 1950s to make thousands of products repel water, stains and heat. They are often called "forever chemicals" because they don't fully break down, accumulating in the environment, humans and animals. Some are toxic at very low levels and have been linked to cancer, birth defects, kidney disease, liver problems, decreased immunity and other serious health issues.

The US Supreme Court Narrows EPA’s Authority to Regulate GHG Under the Clean Air Act

In a 6-3 decision issued today in the case West Virginia v. EPA, the United States Supreme Court held that the U.S. Environmental Protection Agency (EPA) exceeded its statutory authority when it attempted to enact an economy-wide, power generation shifting rule in 2015 known as the Clean Power Plan. Writing for the majority, Chief Justice John Roberts cited a series of recent decisions where the Court held that administrative agencies had attempted to regulate the economy far beyond Congressionally delegated powers, implicating serious constitutional separation of powers questions. Citing its "major questions" doctrine, the Court concluded that Section 111 of the Clean Air Act does not empower EPA to substantially restructure the American energy market. Rather, the statute empowers the agency to regulate emissions and not direct an economy-wide shift of energy sources, that Congress "conspicuously and repeatedly" rejected. The Court noted that its "major questions" doctrine refers to "an identifiable body of law that has developed over a series of significant cases all addressing a particular and recurring problem: agencies asserting highly consequential power beyond what Congress could reasonably be understood to have granted." The decision does not disturb EPA's authority to regulate GHGs under the Clean Air Act, but significantly narrows that authority. The decision also fails to directly address the scope of EPA's authority to regulated GHG's under Section 111(d) of the Clean Air Act.
