Trump's Latest EPA Rollback Lets Polluters Spew More Lead, Arsenic, Mercury

Trump's Environmental Protection Agency (EPA) has weakened yet another safeguard against air pollution in the midst of a respiratory pandemic.
The agency finalized a rollback Thursday of the Clinton-era "once in, always in" policy that required major polluters like industrial plants and refineries to maintain the highest possible levels of pollution controls as long as they continued to operate, Reuters reported.
"This is a lawless action that will undoubtedly increase carcinogens and other deadly pollution in our air," Clinton EPA administrator Carol Browner said in a statement reported by The Hill. "Taking this action during a global pandemic that preys upon people with existing respiratory ailments further confirms that for Andrew Wheeler and the political leadership of the EPA the cruelty is the point."
The agency first proposed reversing the rule in 2018, according to Reuters. The 1995 policy required that major polluters use maximum achievable control technology standards (MACT) throughout the lifetime of their operations. The new policy will allow these facilities to use less stringent standards after they reduce emissions. The so-called "major sources" that reduce their emissions of hazardous air pollutants (HAP) will be reclassified as "area sources," emitters like gas stations or dry cleaners that emit less than 10 tons of a single pollutant or 25 tons of multiple pollutants each year.
"This action reduces regulatory burden and provides a level of fairness and flexibility for sources that reduce HAP emissions below major source thresholds and reclassify as area sources," the agency explained.
EPA Administrator Andrew Wheeler argued that the change would incentivize companies to invest in better technology to reduce emissions.
"Today's action is an important step to further President Trump's regulatory reform agenda by providing meaningful incentives for investment that prevents hazardous air pollution," he said in a statement reported by The Hill.
However, Natural Resources Defense Council (NRDC) senior attorney John Walke said the reversal was entirely unnecessary. He said plants had already installed emission-reduction technology and had been maintaining the requirement that they reduce pollution 95 to 98 percent for decades.
"It's the triumph of extreme ideology over public health, common sense and the law," he told The Hill.
Walke further said on Twitter that the rollback would allow plants to emit two to ten times more hazardous air pollutants than before. This includes toxins like mercury, lead, arsenic, asbestos and benzene that can cause cancer, brain damage, fetal damage and premature death.
The EPA itself acknowledged the new policy could cause as many as 1,258 tons of additional pollutants to enter the air every year.
The Sierra Club pointed out that the change would disproportionately impact low income communities and communities of color that tend to live closer to polluting plants. It comes as scientists warn that exposure to air pollution might increase the risk of dying of the new coronavirus, and Black and Hispanic Americans are contracting and dying of the new virus at higher rates.
"Despite … the renewed national focus on environmental justice, Wheeler is showing there is no level that he will not stoop to in order to placate polluters and carrying out the wishes of his disgraced predecessor, former EPA Administrator Scott Pruitt," national director of campaigns for the Sierra Club Mary Anne Hitt said in a statement. "Sierra Club, however, will continue to fight for the communities Wheeler has chosen to ignore. We will fight this reckless and unlawful rollback, in order to ensure that the American public is safe from dangerous air pollution."
The NRDC also promised to fight the change, and the Environmental Defense Fund told Reuters it would sue to reverse the rollback.- EPA Chief Previews a Second Trump Term: More Deregulation ... ›

The speed and scale of the response to COVID-19 by governments, businesses and individuals seems to provide hope that we can react to the climate change crisis in a similarly decisive manner - but history tells us that humans do not react to slow-moving and distant threats.
A Game of Jenga
<p>Think of it as a game of Jenga and the planet's climate system as the tower. For generations, we have been slowly removing blocks. But at some point, we will remove a pivotal block, such as the collapse of one of the major global ocean circulation systems, for example the Atlantic Meridional Overturning Circulation (AMOC), that will cause all or part of the global climate system to fall into a planetary emergency.</p><p>But worse still, it could cause runaway damage: Where the tipping points form a domino-like cascade, where breaching one triggers breaches of others, creating an unstoppable shift to a radically and swiftly changing climate.</p><p>One of the most concerning tipping points is mass methane release. Methane can be found in deep freeze storage within permafrost and at the bottom of the deepest oceans in the form of methane hydrates. But rising sea and air temperatures are beginning to thaw these stores of methane.</p><p>This would release a powerful greenhouse gas into the atmosphere, 30-times more potent than carbon dioxide as a global warming agent. This would drastically increase temperatures and rush us towards the breach of other tipping points.</p><p>This could include the acceleration of ice thaw on all three of the globe's large, land-based ice sheets – Greenland, West Antarctica and the Wilkes Basin in East Antarctica. The potential collapse of the West Antarctic ice sheet is seen as a key tipping point, as its loss could eventually <a href="https://science.sciencemag.org/content/324/5929/901" target="_blank">raise global sea levels by 3.3 meters</a> with important regional variations.</p><p>More than that, we would be on the irreversible path to full land-ice melt, causing sea levels to rise by up to 30 meters, roughly at the rate of two meters per century, or maybe faster. Just look at the raised beaches around the world, at the last high stand of global sea level, at the end of the Pleistocene period around 120,0000 years ago, to see the evidence of such a warm world, which was just 2°C warmer than the present day.</p>Cutting Off Circulation
<p>As well as devastating low-lying and coastal areas around the world, melting polar ice could set off another tipping point: a disablement to the AMOC.</p><p>This circulation system drives a northward flow of warm, salty water on the upper layers of the ocean from the tropics to the northeast Atlantic region, and a southward flow of cold water deep in the ocean.</p><p>The ocean conveyor belt has a major effect on the climate, seasonal cycles and temperature in western and northern Europe. It means the region is warmer than other areas of similar latitude.</p><p>But melting ice from the Greenland ice sheet could threaten the AMOC system. It would dilute the salty sea water in the north Atlantic, making the water lighter and less able or unable to sink. This would slow the engine that drives this ocean circulation.</p><p><a href="https://www.carbonbrief.org/atlantic-conveyor-belt-has-slowed-15-per-cent-since-mid-twentieth-century" target="_blank">Recent research</a> suggests the AMOC has already weakened by around 15% since the middle of the 20th century. If this continues, it could have a major impact on the climate of the northern hemisphere, but particularly Europe. It may even lead to the <a href="https://ore.exeter.ac.uk/repository/handle/10871/39731?show=full" target="_blank" rel="noopener noreferrer">cessation of arable farming</a> in the UK, for instance.</p><p>It may also reduce rainfall over the Amazon basin, impact the monsoon systems in Asia and, by bringing warm waters into the Southern Ocean, further destabilize ice in Antarctica and accelerate global sea level rise.</p>The Atlantic Meridional Overturning Circulation has a major effect on the climate. Praetorius (2018)
Is it Time to Declare a Climate Emergency?
<p>At what stage, and at what rise in global temperatures, will these tipping points be reached? No one is entirely sure. It may take centuries, millennia or it could be imminent.</p><p>But as COVID-19 taught us, we need to prepare for the expected. We were aware of the risk of a pandemic. We also knew that we were not sufficiently prepared. But we didn't act in a meaningful manner. Thankfully, we have been able to fast-track the production of vaccines to combat COVID-19. But there is no vaccine for climate change once we have passed these tipping points.</p><p><a href="https://www.weforum.org/reports/the-global-risks-report-2021" target="_blank">We need to act now on our climate</a>. Act like these tipping points are imminent. And stop thinking of climate change as a slow-moving, long-term threat that enables us to kick the problem down the road and let future generations deal with it. We must take immediate action to reduce global warming and fulfill our commitments to the <a href="https://www.ipcc.ch/sr15/" target="_blank" rel="noopener noreferrer">Paris Agreement</a>, and build resilience with these tipping points in mind.</p><p>We need to plan now to mitigate greenhouse gas emissions, but we also need to plan for the impacts, such as the ability to feed everyone on the planet, develop plans to manage flood risk, as well as manage the social and geopolitical impacts of human migrations that will be a consequence of fight or flight decisions.</p><p>Breaching these tipping points would be cataclysmic and potentially far more devastating than COVID-19. Some may not enjoy hearing these messages, or consider them to be in the realm of science fiction. But if it injects a sense of urgency to make us respond to climate change like we have done to the pandemic, then we must talk more about what has happened before and will happen again.</p><p>Otherwise we will continue playing Jenga with our planet. And ultimately, there will only be one loser – us.</p>By John R. Platt
The period of the 45th presidency will go down as dark days for the United States — not just for the violent insurgency and impeachment that capped off Donald Trump's four years in office, but for every regressive action that came before.
