New analysis: Americans across the country suffered from high ozone pollution levels of this summer

In addition to checking the temperature and the chance of rain before leaving home, many people have been forced to add a new indicator to their daily weather check – air quality.

Ground-level ozone pollution – more commonly known as smog – reached dangerous levels across the U.S. this summer. EDF’s new analysis found that almost every state experienced unhealthy levels of it, with millions of Americans exposed to dangerous air pollution.

The current national standard for ground-level ozone pollution is 70 parts per billion. As you can see from the maps above, 45 states had at least one day between March and August with levels that exceeded that limit.

However, there is a substantial and growing body of scientific evidence that shows serious health effects from ground-level ozone exposure at levels below the current standard. When the data is expanded to consider ground-level ozone levels greater than 60 parts per billion, which would be a health-based standard more consistent with the scientific evidence, the picture of summer ozone levels is even more concerning – all but one state (Hawaii) had at least one day with levels that exceeded that amount.

Our analysis also found:

  • The Western U.S. experienced the worst ozone levels in the country this summer. California, Arizona and Colorado experienced the most high-ozone days between March and August.
  • 343 counties recorded at least one high-ozone day. San Bernardino, California recorded the most exceedances – 112 high-ozone days between March and August, including almost every day in July and August.
  • More than 31 million people live in the 24 counties that had more than 20 high-ozone days between March and August, including Denver County in Colorado, Maricopa County in Arizona, and Los Angeles County in California.
  • If you use the more health-protective standard of 60 parts per billion, a majority of days between March and April had unhealthy ozone levels across the Western U.S.
  • In Arizona, under the 60 parts per billion standard, 89% of days between March and August had unhealthy ozone levels somewhere in the state.

There were many wildfires this summer and wildfire smoke is one of the sources that can contribute to elevated levels of ozone pollution. EPA establishes standards based on health science alone, and the agency has long had policies in place that allow states to account for truly exceptional events. Our analysis includes all recorded high ozone readings and does not exclude any high ozone days

Driving the electric vehicle transition: auto companies and states step up to lead

If you watched any major televised sporting events this year, from the NCAA Final Four to the Super Bowl, you saw ad after ad showcasing American auto companies’ new electric cars. It’s proof that electric vehicles (EVs) are ready for a mainstream market – you don’t pay Will Ferrell and LeBron James to promote your car just to niche buyers.

Momentum is clearly building. Companies are prepared to capitalize on the economic benefits of EVs, for both consumers and autoworkers, as well as the climate and health benefits that all Americans will see.

In the last three months, some of the largest automakers in the U.S. and the world have committed to dramatically expanding their EV lineup. They have announced plans to invest billions of dollars in EV development, and plans to transition to an all-electric future by 2035 or earlier.

The Biden administration made a commitment last week to reduce U.S. climate pollution by at least 50 percent by 2030 – a commitment that was supported by major automakers and that will require significant emission reductions from the transportation sector.

States are also playing a leading role in driving progress. Last week, a bipartisan group of 12 governors detailed the important role that states have played in deploying zero-emitting vehicles and urged the Biden administration to move forward with ambitious standards that would eliminate pollution from all motor vehicles. And next week, the California Air Resources Board will hold a workshop related to its development of Advanced Clean Car II standards – standards that are expected to help the state ensure all new vehicles sold in California are zero-emitting by 2035.

The transportation sector is responsible for over a quarter of U.S. climate pollution – more than any other sector. The transportation sector also emits a slew of health-harming pollutants, including oxides of nitrogen and particulate pollution. The transportation sector is key to meaningful climate action.

To achieve meaningful reductions in transportation pollution, it will be key for the administration follow automakers’ commitments and state leadership with bold, decisive air pollution standards that put the U.S. on a path to ensure all new vehicles are zero-emitting no later than 2035 for passenger cars and trucks, and no later than 2040 for freight trucks and buses.

Trump administration decision on soot ignores science, risks Americans’ health

Today, the Trump administration finalized a rushed and inadequate review of our national particle pollution standard – otherwise known as PM 2.5, or soot. They ignored public input and the latest body of health science, and decided to keep a weak standard in place.

The decision by Trump’s EPA means that Americans – particularly Black, Latino, Indigenous and other communities of color – will be exposed to elevated levels of harmful air pollution. It’s a decision that the incoming Biden-Harris administration should immediately reverse and replace with strong standards that reflect the clear scientific evidence and protect all Americans.

Here are three things you should know:

The Trump administration’s air toxics loophole would intensify environmental injustice

(Some statistics in this post were corrected on June 24, 2021)

One of the most disturbing aspects of the new coronavirus crisis is that people already struggling with underlying respiratory conditions seem to be at greater risk. This means that vulnerable communities already bearing the brunt of the health harms from dangerous pollution may suffer even more.

Yet the Trump administration has spent the last few weeks racing to roll back policies that safeguard the air we breathe. These rollbacks often impact vulnerable communities the most as well.

One such roll back is the proposed air toxics loophole, which would allow thousands of large industrial facilities nationwide to evade pollution controls and emit more toxic air pollution. In a previous post, we presented analysis of EPA’s own data indicating that the loophole could lead to an increase in emissions of hazardous air pollutants like benzene and mercury by over 49 million pounds across 48 states. We’ve now done further analysis and found that the facilities likely to increase toxic air pollution under this loophole are disproportionately located in vulnerable communities – leading to increased exposure to these dangerous pollutants for heavily minority and low-income neighborhoods.

Power company commitments to cut carbon pollution are an important step for our climate and health. Here’s what we need next.

Arizona’s largest utility, Arizona Public Service, has joined over a dozen other power companies across the U.S. that have committed to delivering 100% carbon-free electricity by 2050. These commitments, which add to momentum for ambitious climate action and would significantly reduce health-harming pollutants that contribute to soot and smog, are a key step in addressing one of our nation’s leading sources of climate pollution. They also highlight the types of action that will be required across all sectors of the U.S. economy to reach net-zero economy-wide carbon pollution by mid-century, a target guided by science and supported in recent bills introduced in the U.S. Senate and House of Representatives.

Not only do these commitments show strong federal policy is feasible, they underscore that the Trump administration’s efforts to dismantle limits on carbon pollution from existing power plants ignore the most effective strategies for reducing pollution from the power sector. In fact, nine of the nation’s leading power companies recently submitted a brief in court opposing the Trump administration’s rollback for this very reason.

At the same time, these commitments by themselves are not enough. Due to the cost-effective pollution reduction opportunities in the power sector and the urgent need to reduce climate pollution by electrifying other sectors, even more ambitious near-term targets from power companies will be needed to achieve net-zero emissions economy-wide by 2050. In addition, commitments alone from power companies must be followed up with concrete actions that will achieve real reductions in carbon pollution – and reduce other harmful pollutants associated with premature death and respiratory illnesses.

EPA data emphasizes danger of Trump Administration’s “air toxics loophole”

There’s been a lot of talk recently about the Trump administration undermining our protections against dangerous air pollution during the new coronavirus crisis. But they didn’t just start now.

Possible increase in total air toxic emissions from a subset of facilities eligible to reclassify under the air toxics loophole, aggregated at state and city level. In many areas, this loophole could lead to a quadrupling of air toxics from these facilities. Graphic by EDF.

Air pollution is linked to many of the underlying conditions that make some people especially vulnerable to the virus. For years, the administration has taken actions that would put more of that unhealthy pollution in our air – including through a proposed loophole to our safeguards against air pollution from large industrial sources. Data released by EPA itself shows how this loophole – which the Administration could finalize in the coming months – might expose millions of Americans to a huge increase in toxic air pollution.

Last July, EPA Administrator Andrew Wheeler proposed to create an air toxics loophole allowing large industrial facilities to increase their emissions of dangerous pollutants. When this proposed rule first emerged, EDF pointed out that EPA’s own data shows more than 3,900 large industrial facilities across the country are potentially eligible to take advantage of this loophole.

But additional data on just a subset of these facilities, released by EPA after the proposal came out, indicates that the proposal could lead to millions of pounds of additional toxic air pollution across 48 states – with many of these facilities located in areas where millions of Americans live and work.

The proposed air toxics loophole would undermine clean air safeguards for large industrial facilities across the country that are currently subject to stringent standards for the emission of mercury, benzene, and other hazardous air pollutants that may cause cancer and have other harmful health impacts. Under the proposal, many of these facilities would be eligible to “reclassify” themselves as smaller sources subject to weaker standards or no standards at all – and therefore could operate with weaker, or no, air pollution controls.

(The proposal would codify a four-page memo that Trump’s EPA issued in January 2018 – with no analysis of air pollution or health impacts. EDF, a coalition of environmental groups, and the State of California challenged that memo in court.  Although the D.C. Circuit rejected these challenges on procedural grounds, the court also found that the memo has no legal force or effect and cannot be relied upon by state permitting authorities or sources.)

In September, EDF and 34 public health, environmental justice, labor and environmental organizations submitted comments strongly opposing the proposed rule. EDF and four other environmental organizations also submitted detailed technical and legal comments emphasizing the danger the rule poses to public health.

Near the close of the comment period, EPA released additional data, including identifying information for specific facilities that could be eligible to reclassify under the proposed rule. EDF analyzed this additional data for clues about the devastating health and environmental impacts the air toxics loophole could have. In response to this additional data, EDF submitted supplemental comments to EPA.

Among other things, our analysis found:

  • EPA’s data covers more than 2,500 facilities that would be eligible to reclassify and increase their emission of dangerous pollutants. EPA identified more than 2,500 facilities that are currently subject to stringent Maximum Achievable Control Technology standards but under the loophole could avoid complying with those standards. This large number of facilities still represents only a subset of the nearly 4,000 facilities nationwide that EPA estimated would be potentially eligible to reclassify under the proposal.
  • A potential 480% increase in nationwide emissions of air toxics from these facilities. While it’s difficult to know if and by how much facilities would increase emissions if they were to take advantage of the proposed loophole, EDF estimates that total air toxics emissions could increase by about 49.2 million pounds per year if all the eligible facilities were to increase their emissions to the maximum extent permitted under the loophole. (The value was estimated by looking at the difference between current total air toxics emissions at these facilities and emissions if facilities increased total air toxics emissions to 75% of 25 tons per year – the threshold that would make these facilities major again – consistent with EPA’s approach.) Due to missing data for some of the facilities on the EPA list, however, this estimate is based on only 60% of the 2,500 facilities identified by EPA – so it could well underestimate the potential increase in emissions that would result from this proposal.

  • The proposed rule could expose millions of Americans in communities across the country to increases in toxic air pollution. Our analysis found facilities potentially eligible to use the loophole to increase their emissions of dangerous pollutants in 48 states. The greatest increases are concentrated in Texas, California, Michigan, and Louisiana. More than 3.7 million people live in the ten cities with the greatest possible increase in air toxics from this loophole.

After EPA issued the January 2018 memo that first opened the air toxics loophole, EDF issued a white paper finding that it could affect as many as 26 facilities in the Houston-Galveston region alone – and lead to hundreds of thousands of pounds of additional toxic pollution. Now, EPA’s own data reinforces the devastating impact of this loophole, from California to Michigan. EDF will continue to oppose this dangerous failure of EPA to uphold its responsibility to safeguard human health and the environment.
