Things Biden and the Democrats did, this week #13

April 5-12 2024

President Biden announced the cancellation of a student loan debt for a further 277,000 Americans. This brings the number of a Americans who had their debt canceled by the Biden administration through different means since the Supreme Court struck down Biden's first place in 2023 to 4.3 million and a total of $153 billion of debt canceled so far. Most of these borrowers were a part of the President's SAVE Plan, a debt repayment program with 8 million enrollees, over 4 million of whom don't have to make monthly repayments and are still on the path to debt forgiveness.

President Biden announced a plan that would cancel student loan debt for 4 million borrowers and bring debt relief to 30 million Americans The plan takes steps like making automatic debt forgiveness through the public service forgiveness so qualified borrowers who don't know to apply will have their debts forgiven. The plan will wipe out the interest on the debt of 23 million Americans. President Biden touted how the plan will help black and Latino borrowers the most who carry the heavily debt burdens. The plan is expected to go into effect this fall ahead of the election.

President Biden and Vice-President Harris announced the closing of the so-called gun show loophole. For years people selling guns outside of traditional stores, such as at gun shows and in the 21st century over the internet have not been required to preform a background check to see if buyers are legally allowed to own a fire arm. Now all sellers of guns, even over the internet, are required to be licensed and preform a background check. This is the largest single expansion of the background check system since its creation.

The EPA published the first ever regulations on PFAS, known as forever chemicals, in drinking water. The new rules would reduce PFAS exposure for 100 million people according to the EPA. The Biden Administration announced along side the EPA regulations it would make available $1 billion dollars for state and local water treatment to help test for and filter out PFAS in line with the new rule. This marks the first time since 1996 that the EPA has passed a drinking water rule for new contaminants.

The Department of Commerce announced a deal with microchip giant TSMC to bring billions in investment and manufacturing to Arizona. The US makes only about 10% of the world's microchips and none of the most advanced chips. Under the CHIPS and Science Act the Biden Administration hopes to expand America's high-tech manufacturing so that 20% of advanced chips are made in America. TSMC makes about 90% of the world's advanced chips. The deal which sees a $6.6 billion dollar grant from the US government in exchange for $65 billion worth of investment by TSMC in 3 high tech manufacturing facilities in Arizona, the first of which will open next year. This represents the single largest foreign investment in Arizona's history and will bring thousands of new jobs to the state and boost America's microchip manufacturing.

The EPA finalized rules strengthening clean air standards around chemical plants. The new rule will lower the risk of cancer in communities near chemical plants by 96% and eliminate 6,200 tons of toxic air pollution each year. The rules target two dangerous cancer causing chemicals, ethylene oxide and chloroprene, the rule will reduce emissions of these chemicals by 80%.

the Department of the Interior announced it had beaten the Biden Administration goals when it comes to new clean energy projects. The Department has now permitted more than 25 gigawatts of clean energy projects on public lands, surpass the Administrations goal for 2025 already. These solar, wind, and hydro projects will power 12 million American homes with totally green power. Currently 10 gigawatts of clean energy are currently being generated on public lands, powering more than 5 million homes across the West. 

The Department of Transportation announced $830 million to support local communities in becoming more climate resilient. The money will go to 80 projects across 37 states, DC, and the US Virgin Islands The projects will help local Infrastructure better stand up to extreme weather causes by climate change.

The Senate confirmed Susan Bazis, Robert White, and Ann Marie McIff Allen to lifetime federal judgeships in Nebraska, Michigan, and Utah respectively. This brings the total number of judges appointed by President Biden to 193

"The sleeping giant of the US Environmental Protection Agency (EPA) has stirred.

In the past month, an avalanche of anti-pollution rules, targeting everything from toxic drinking water to planet-heating gases in the atmosphere, have been issued by the agency. Belatedly, the sizable weight of the US federal government is being thrown at longstanding environmental crises, including the climate emergency.

On Thursday [May 18, 2023], the EPA’s month of frenzied activity was crowned by the toughest ever limits upon carbon pollution from America’s power sector, with large, existing coal and gas plants told they must slash their emissions by 90% or face being shut down.

The measure will, the EPA says, wipe out more than 600m tons of carbon emissions over the next two decades, about double what the entire UK emits each year. But even this wasn’t the biggest pollution reduction announced in recent weeks.

In April, new emissions standards for cars and trucks will eliminate an expected 9bn tons of CO2 by the mid-point of the century, while separate rules issued late last year aim to slash hydrofluorocarbons, planet-heating gases used widely in refrigeration and air conditioning, by 4.6bn tons in the same timeframe. Methane, another highly potent greenhouse gas, will be curtailed by 810m tons over the next decade in another EPA edict.

In just a few short months the EPA, diminished and demoralized under Donald Trump, has flexed its regulatory muscles to the extent that 15bn tons of greenhouse gases – equivalent to about three times the US’s carbon pollution, or nearly half of the entire world’s annual fossil fuel emissions – are set to be prevented, transforming the power basis of Americans’ cars and homes in the process...

If last year’s Inflation Reduction Act (IRA), with its $370bn in clean energy subsidies and enticements for electric car buyers, was the carrot to reducing emissions, the EPA now appears to be bringing a hefty stick.

The IRA should help reduce US emissions by about 40% this decade but the cut needs to be deeper, up to half of 2005 levels, to give the world a chance of avoiding catastrophic heatwaves, wildfires, drought and other climate calamities. The new rules suddenly put America, after years of delay and political rancor, tantalizingly within reach of this...

“It’s clear we’ve reached a pivotal point in human history and it’s on all of us to act right now to protect our future,” said Michael Regan, the administrator of the EPA, in a speech last week at the University of Maryland. The venue was chosen in a nod to the young, climate-concerned voters Joe Biden hopes to court in next year’s presidential election, and who have been dismayed by Biden’s acquiescence to large-scale oil and gas drilling.

“Folks, this is our future we are talking about, and we have a once-in-a-generation opportunity for real climate action,” [Michael Regan, the administrator of the EPA], added. “Failure is not an option, indifference is not an option, inaction is not an option.” ...

It’s not just climate the EPA has acted upon in recent months. There are new standards for chemical plants, such as those that blight the so-called "Cancer Alley" the US, from emitting cancer-causing toxins such as benzene, ethylene oxide and vinyl chloride. New rules curbing mercury, arsenic and lead from industrial facilities have been released, as have tighter limits on emissions of soot and the first ever regulations targeting the presence of per- and polyfluoroalkylsubstances (or PFAS) in drinking water.” ...

For those inside the agency, the breakneck pace has been enervating. “It’s definitely a race against time,” said one senior EPA official, who asked not to be named. “The clock is ticking. It is a sprint through a marathon and it is exhausting.” ...

“We know the work to confront the climate crisis doesn’t stop at strong carbon pollution standards,” said Ben Jealous, the executive director of the Sierra Club.

“The continued use or expansion of fossil power plants is incompatible with a livable future. Simply put, we must not merely limit the use of fossil fuel electricity – we must end it entirely.”"

of fucking course.....they fucking coated paper straws with pfas......its a fucking nightmare

--

Long-lasting 'forever chemicals', which can cause damaging health issues, found in 18/20 brands of paper straws

In the first analysis of its kind in Europe, and only the second in the world, Belgian researchers tested 39 brands of straws for the group of synthetic chemicals known as poly- and perfluoroalkyl substances (PFAS).

PFAS were found in the majority of the straws tested and were most common in those made from paper and bamboo, the study, published in the peer-reviewed journal Food Additives and Contaminants, found.

PFAS are used to make everyday products, from outdoor clothing to non-stick pans, resistant to water, heat and stains. They are, however, potentially harmful to people, wildlife and the environment.

They break down very slowly over time and can persist over thousands of years in the environment, a property that has led to them being known as "forever chemicals."

They have been associated with a number of health problems, including lower response to vaccines, lower birth weight, thyroid disease, increased cholesterol levels, liver damage, kidney cancer and testicular cancer.

"Straws made from plant-based materials, such as paper and bamboo, are often advertised as being more sustainable and eco-friendly than those made from plastic," says researcher Dr Thimo Groffen, an environmental scientist at the University of Antwerp, who is involved in this study.

"However, the presence of PFAS in these straws means that's not necessarily true."

A growing number of countries, including the UK and Belgium, have banned sale of single-use plastic products, including drinking straws, and plant-based versions have become popular alternatives.

A recent study found PFAS in plant-based drinking straws in the US. Dr Groffen and colleagues wanted to find out if the same was true of those on sale in Belgium.

To explore this further, the research team purchased 39 different brands of drinking straw made from five materials -- paper, bamboo, glass, stainless steel and plastic.

The straws, which were mainly obtained from shops, supermarkets and fast-food restaurants, then underwent two rounds of testing for PFAS.

The majority of the brands (27/39, 69%) contained PFAS, with 18 different PFAS detected in total.

The paper straws were most likely to contain PFAS, with the chemicals detected in 18/20 (90%) of the brands tested. PFAS were also detected in 4/5 (80%) brands of bamboo straw, 3/4 (75%) of the plastic straw brands and 2/5 (40%) brands of glass straw. They were not detected in any of the five types of steel straw tested.

The most commonly found PFAS, perfluorooctanoic acid (PFOA), has been banned globally since 2020.

Also detected were trifluoroacetic acid (TFA) and trifluoromethanesulfonic acid (TFMS), "ultra-short chain" PFAS which are highly water soluble and so might leach out of straws into drinks.

The PFAS concentrations were low and, bearing in mind that most people tend to only use straws occasionally, pose a limited risk to human health. However, PFAS can remain in the body for many years and concentrations can build up over time.

"Small amounts of PFAS, while not harmful in themselves, can add to the chemical load already present in the body," says Dr Groffen.

It isn't known whether the PFAS were added to the straws by the manufacturers for waterproofing or whether were the result of contamination. Potential sources of contamination include the soil the plant-based materials were grown in and the water used in the manufacturing process.

However, the presence of the chemicals in almost every brand of paper straw means it is likely that it was, in some cases, being used as a water-repellent coating, say the researchers.

The study's other limitations include not looking at whether the PFAS would leach out of the straws into liquids.

Dr Groffen concludes: "The presence of PFAS in paper and bamboo straws shows they are not necessarily biodegradable.

"We did not detect any PFAS in stainless steel straws, so I would advise consumers to use this type of straw -- or just avoid using straws at all."

'Forever chemicals' destroyed by simple new method

PFAS, a group of manufactured chemicals commonly used since the 1940s, are called "forever chemicals" for a reason. Bacteria can't eat them; fire can't incinerate them; and water can't dilute them. And, if these toxic chemicals are buried, they leach into surrounding soil, becoming a persistent problem for generations to come.

Now, Northwestern University chemists have done the seemingly impossible. Using low temperatures and inexpensive, common reagents, the research team developed a process that causes two major classes of PFAS compounds to fall apart, leaving behind only benign end products.

The simple technique potentially could be a powerful solution for finally disposing of these harmful chemicals, which are linked to many dangerous health effects in humans, livestock and the environment.

"PFAS has become a major societal problem," said Northwestern's William Dichtel, who led the study. "Even just a tiny, tiny amount of PFAS causes negative health effects, and it does not break down. We can't just wait out this problem. We wanted to use chemistry to address this problem and create a solution that the world can use. It's exciting because of how simple—yet unrecognized—our solution is."

PFAS have earned the name "forever chemicals" with good reason—the man-made compounds, which can take thousands of years to degrade and are found in everything from grease-resistant food packaging to water-repellent clothing, have made their way into nearly half the U.S. tap water supply. Now, in a study featured in the Journal of Hazardous Materials, New Jersey Institute of Technology chemists have demonstrated a new lab-based method to detect traces of PFAS from food packaging material, water and soil samples in just three minutes or less.

You guys have probably heard that the EPA just set new Maximum Contaminant Levels (MCLs) for the first time in decades for PFAS, which is BIG news in the industry, but not a surprise. I've been in meetings for months hearing about how new PFAS regulations were in the works, and the consensus in the environmental sector is that it's long overdue. But for the rest of you who've never heard of PFAS before I can break down what the big issues are and why they've taken so long to address.

^stolen from pubchem

So PFAS stands for per- and poly- flouroalkyl substances, and it's not one chemical compound, but an entire class of thousands of chemicals that have these chains of Carbon and Flourine atoms. For anybody who doesn't have a chem background fluorine is a nasty atom, it has seven electrons in its valence shell and it will do anything to fill it up to eight, creating incredibly strong bonds.

So you have really strong C-F bonds and these chains of C and F atoms are hydrophobic, which means these compounds are durable and water resistant, which makes them great for all sorts of industrial uses. And we've used them in everything: clothing, fast food wrappers, paints, solar panels, and non-stick pans just to start.

Unfortunately, these wonder chemicals are PBTM- Persistent, Bioaccumulative, Toxic, and Mobile. They don't break down, they build up in the food chain, they have adverse health effects, and even though C-F chains are hydrophobic, additional compounds connected to them can make them soluble in water (so they're in our drinking water). We're starting to realize PFAS can raise cholesterol, inhibit immune response, interfere with your thyroid (part of your hormonal system), cause liver toxicity, is linked to cancer, and more!

At this point you're probably starting to think wtf, how did we allow the continued widespread use of these chemicals? Well, we have phased out quite a few high profile PFAS compounds including PFOA and PFOS, but we still want to regulate and test for them in our drinking water. While PFAS is in many different products, the biggest sources of contamination are industrial runoff, areas where fire fighting foams were tested and used, landfills that leach out PFAS into the surrounding area, and wastewater treatment plants. So don't feel too stressed about eating microwave popcorn or using nail polish.

The reason these regulations took so long to implement was because of how difficult it was to connect such small amounts of PFAS with health hazards. The level of concern for PFAS is extremely low- in the ppt (parts per trillion) range. When I sample for contaminants I'm generally testing in the ppm range and higher, for PFAS we're looking an entire scale lower. We literally did not have the technology before the last few decades to detect PFAS in the ppt range in water, let alone study their effects (you can't just impose massive regulations without any proof to back it up).

States that currently have PFAS limits in drinking water have mostly capped it in the 10-70 ppt range. The new MCLs are 4-10 ppt for the six PFAS compounds the EPA addressed, which are six of the most common and most studied PFAS compounds. Most of the bitching I've seen is about how much this will cost and that the new limits are too low. The conservative take on this is that there isn't enough evidence to support such low MCLs, although most people in the environmental industry feel that more and more research keeps coming out and will keep coming out (remember studying such small amounts of anything is difficult) to support these levels. On the other side of the spectrum, there's the consensus that this is just the beginning and that more and more regulations on PFAS will be needed.

And they're in the works! I saw a proposed rule by the EPA that would ban 12 (already defunct) PFAS substances from pesticides. It wouldn't really affect the current manufacturing of pesticides, but it would be a safeguard from letting them back into the manufacturing process in case of a conservative presidency.

If you're still here I'd like to end on the note that as our science improves, our understanding of how we have impacted the environment and our health will improve. We are constantly going to find out about the adverse effects of new chemicals or things that we may not even produce anymore, and that's a good thing. Over time we are going to make the world a healthier and safer place.

Please! STOP!! We have enough PFAS and microplastics getting into our bodies as it is without you literally eating out of UNSAFE PLASTIC MADE FOR NON-FOOD ITEMS LIKE YOUR CATS POOP!! It does not matter how clean they are, or if they’re brand new. You’re eating out of a potentially toxic container not meant for food. Please. I’m begging you. Please at least line it thoroughly with something. Please

Things Biden and the Democrats did, this week #14

April 12-19 2024

The Department of Commerce announced a deal with Samsung to help bring advanced semiconductor manufacturing and research and development to Texas. The deal will bring 45 billion dollars of investment to Texas to help build a research center in Taylor Texas and expand Samsung's Austin, Texas, semiconductor facility. The Biden Administration estimates this will create 21,000 new jobs. Since 1990 America has fallen from making nearly 40% of the world's semiconductor to just over 10% in 2020.

The Department of Energy announced it granted New York State $158 million to help support people making their homes more energy efficient. This is the first payment out of a $8.8 billion dollar program with 11 other states having already applied. The program will rebate Americans for improvements on their homes to lower energy usage. Americans could get as much as $8,000 off for installing a heat pump, as well as for improvements in insulation, wiring, and electrical panel. The program is expected to help save Americans $1 billion in electoral costs, and help create 50,000 new jobs.

The Department of Education began the formal process to make President Biden's new Student Loan Debt relief plan a reality. The Department published the first set of draft rules for the program. The rules will face 30 days of public comment before a second draft can be released. The Administration hopes the process can be finished by the Fall to bring debt relief to 30 million Americans, and totally eliminate the debt of 4 million former students. The Administration has already wiped out the debt of 4.3 million borrowers so far.

The Department of Agriculture announced a $1 billion dollar collaboration with USAID to buy American grown foods combat global hunger. Most of the money will go to traditional shelf stable goods distributed by USAID, like wheat, rice, sorghum, lentils, chickpeas, dry peas, vegetable oil, cornmeal, navy beans, pinto beans and kidney beans, while $50 million will go to a pilot program to see if USAID can expand what it normally gives to new products. The food aid will help feed people in Bangladesh, Burkina Faso, Burundi, Chad, Democratic Republic of the Congo, Djibouti, Ethiopia, Haiti, Kenya, Madagascar, Mali, Nigeria, Rwanda, South Sudan, Sudan, Tanzania, Uganda, and Yemen.

The Department of the Interior announced it's expanding four national wildlife refuges to protect 1.13 million wildlife habitat. The refuges are in New Mexico, North Carolina, and two in Texas. The Department also signed an order protecting parts of the Placitas area. The land is considered sacred by the Pueblos peoples of the area who have long lobbied for his protection. Security Deb Haaland the first Native American to serve as Interior Secretary and a Pueblo herself signed the order in her native New Mexico.

The Department of Labor announced new work place safety regulations about the safe amount of silica dust mine workers can be exposed to. The dust is known to cause scaring in the lungs often called black lung. It's estimated that the new regulations will save over 1,000 lives a year. The United Mine Workers have long fought for these changes and applauded the Biden Administration's actions.

The Biden Administration announced its progress in closing the racial wealth gap in America. Under President Biden the level of Black Unemployment is the lowest its ever been since it started being tracked in the 1970s, and the gap between white and black unemployment is the smallest its ever been as well. Black wealth is up 60% over where it was in 2019. The share of black owned businesses doubled between 2019 and 2022. New black businesses are being created at the fastest rate in 30 years. The Administration in 2021 Interagency Task Force to combat unfair house appraisals. Black homeowners regularly have their homes undervalued compared to whites who own comparable property. Since the Taskforce started the likelihood of such a gap has dropped by 40% and even disappeared in some states. 2023 represented a record breaking $76.2 billion in federal contracts going to small business owned by members of minority communities. This was 12% of federal contracts and the President aims to make it 15% for 2025.

The EPA announced (just now as I write this) that it plans to add PFAS, known as forever chemicals, to the Superfund law. This would require manufacturers to pay to clean up two PFAS, perfluorooctanoic acid and perfluorooctanesulfonic acid. This move to force manufacturers to cover the costs of PFAS clean up comes after last week's new rule on drinking water which will remove PFAS from the nation's drinking water.

Bonus:

President Biden met a Senior named Bob in Pennsylvania who is personally benefiting from The President's capping the price of insulin for Seniors at $35, and Biden let Bob know about a cap on prosecution drug payments for seniors that will cut Bob's drug bills by more than half.

"Despite a huge amount of political opposition from the chemical industry, the US Environmental Protection Agency (EPA) announced its first regulations aimed at limiting quantities of PFAs, or ‘forever chemicals,’ in American drinking water.

For decades, Polyfluoroalkyl substances or PFAs have been used for coatings that resist fire, oil, stains, and water and are now found in a wide variety of products like waterproof clothing, stain-resistant furniture, food packaging, adhesives, firefighting spray foams, and non-stick cooking surfaces.

There are thousands of PFAS compounds with varying effects and toxicity levels, and the new EPA regulations will require water utilities to test for 6 different classes of them.

The new standards will reduce PFAS exposure—and thereby decrease the health risk—for 100 million people in the U.S.

A fund worth $1 billion for treatment and testing will be made available to water utilities nationwide—part of a $9 billion investment made possible by the 2021 Bipartisan Infrastructure Law to assist communities impacted by PFAS contamination.

“Drinking water contaminated with PFAS has plagued communities across this country for too long,” said EPA Administrator Michael S. Regan in a statement Wednesday.

Under Regan’s leadership, the EPA began in 2021 to establish a roadmap for dealing with widespread PFAS contamination, and so far they’ve gathered much data, including monitoring drinking water, and begun requiring more reports from businesses about use of the unregulated substances.

The agency reported that current peer-reviewed scientific studies have shown that exposure to certain levels of PFAS may lead to a myriad of health issues that are difficult to specify because of the variety of compounds coming from different places.

Regardless, the 66,000 water utility operators will have five years to test for the PFAS pollution and install necessary technology to treat the contamination, which the EPA estimates that 6%–10% of facilities will need. [Note: Deeply curious where they got a number that low, but anyway.]

Records show that some of the manufacturers knew these chemicals posed health hazards. A few major lawsuits in recent years have been settled that sought to hold chemical companies, like 3M, accountable for the environment damage.""

"Based on the latest U.S. guidelines for PFOA in drinking water, rainwater everywhere would be judged unsafe to drink. Although in the industrial world we don't often drink rainwater, many people around the world expect it to be safe to drink and it supplies many of our drinking water sources," Cousins continue.

The Stockholm University team have conducted laboratory and field work on the atmospheric presence and transport of PFAS for the past decade. They have noted that the levels of some harmful PFAS in the atmosphere are not declining notably despite their phase out by the major manufacturer, 3M, already two decades ago. PFAS are known to be highly persistent, but their continued presence in the atmosphere is also due to their properties and natural processes that continually cycle PFAS back to the atmosphere from the surface environment. One important natural cycling process for PFAS is the transport from seawater to marine air by sea spray aerosols, which is another active research area for the Stockholm University team.

[...]

"So now, due to the global spread of PFAS, environmental media everywhere will exceed environmental quality guidelines designed to protect human health and we can do very little to reduce the PFAS contamination. In other words, it makes sense to define a planetary boundary specifically for PFAS and, as we conclude in the paper, this boundary has now been exceeded," said Scheringer.

Excerpt from this New York Times story:

The Biden administration is designating two “forever chemicals,” man-made compounds that are linked to serious health risks, as hazardous substances under the Superfund law, shifting responsibility for their cleanup to polluters from taxpayers.

The new rule announced on Friday empowers the government to force the many companies that manufacture or use perfluorooctanoic acid, also known as PFOA, and perfluorooctanesulfonic acid, known as PFOS, to monitor any releases into the environment and be responsible for cleaning them up. Those companies could face billions of dollars in liabilities.

The pair of compounds are part of a larger family of chemical substances known collectively as PFAS.

The compounds, found in everything from dental floss to firefighting foams to children’s toys, are called forever chemicals because they degrade very slowly and can accumulate in the body and the environment. Exposure to PFAS has been associated with metabolic disorders, decreased fertility in women, developmental delays in children and increased risk of some prostate, kidney and testicular cancers, according to the Environmental Protection Agency.

The chemicals are so ubiquitous that they can be detected in the blood of almost every person in the United States. One recent government study discovered PFAS chemicals in nearly half of the nation’s tap water. In 2022, the E.P.A. found the chemicals could cause harm at levels “much lower than previously understood” and that almost no level of exposure was safe.

The announcement follows an extraordinary move last week from the E.P.A. mandating that water utilities reduce the PFAS in drinking water to near-zero levels. The agency has also proposed to designate seven additional PFAS chemicals as hazardous waste.
