On Wednesday, the Environmental Protection Agency (EPA) announced it would “formally reconsider” the 2009 endangerment finding. This landmark determination recognized greenhouse gases as a danger to public health. This proclamation is part of a broader effort to roll back numerous environmental regulations.
The EPA’s actions include revising rules on pollution from coal-fired power plants and electric vehicles. They also plan to narrow the definition of protected waterways under the Clean Water Act, impacting wetlands and streams.
Sweeping Changes to Environmental Rules
These decisions mark the beginning of a potentially years-long process to repeal or revise 31 environmental rules. these rules cover a wide range of industries and pollutants:
- Wastewater discharges for oil and gas extraction facilities
- Oil and gas industry reporting through a greenhouse gas program
- Rules governing coal ash and coal-fired power plants
- National air quality standards for particulate matter
- emission standards for industrial air pollutants
- Rules to reduce air pollution that causes haze
- Regulations restricting vehicle emissions
EPA Administrator’s Stance
EPA administrator Lee Zeldin expressed strong support for the changes. “We are driving a dagger through the heart of the climate-change religion and ushering in America’s Golden Age,” Zeldin stated. He further emphasized the importance of the move, writing, “Today is the most consequential day of deregulation in American history.”
The EPA’s 2009 “endangerment finding” has been a cornerstone of U.S. climate action. It established that planet-warming greenhouse gases endanger public health and welfare. This determination, made under the Clean Air Act, provides the legal foundation for numerous climate regulations affecting vehicles and other pollution sources.
Specifically, the agency steadfast in 2009 that six greenhouse gases present in the Earth’s atmosphere pose a health risk to current and future generations. These gases include:
- Carbon dioxide
- Methane
- Nitrous oxide
- Hydrofluorocarbons
- Perfluorocarbons
- Sulfur hexafluoride
The EPA also concluded that motor vehicle emissions endanger public health.
Reconsidering the Endangerment Finding
“after 16 years, EPA will formally reconsider the Endangerment finding,” Zeldin announced on Wednesday. “The Trump Administration will not sacrifice national prosperity, energy security, and the freedom of our people for an agenda that throttles our industries, our mobility, and our consumer choice while benefiting adversaries overseas.”
In addition to regulatory changes, the EPA is also moving to eliminate positions focused on diversity, equity, and inclusion (DEI) and environmental justice. This decision follows an executive order on “ending radical and wasteful government DEI programs and preferences,” according to a March 11 memo from Zeldin.
Climate experts Criticize EPA Actions
Climate change experts have voiced strong criticism of the EPA’s moves. They suggest the effort to strike down environmental protections will face meaningful legal challenges.
David Doniger, a climate expert at the Natural Resources Defense Council, stated, “In the face of overwhelming science, it’s impossible to think that the EPA could develop a contradictory finding that would stand up in court.”
Michael Mann, a climate scientist at the University of Pennsylvania, characterized the EPA’s action as “just the latest form of Republican climate denial. They can no longer deny climate change is happening, so rather they’re pretending it’s not a threat, despite the overwhelming scientific evidence that it is indeed, perhaps, the greatest threat that we face today.”
EPA’s Reconsideration of Greenhouse Gas Endangerment Finding: A Q&A Guide
What is the EPA’s Endangerment Finding?
The EPA’s “endangerment finding,” established in 2009 under the Clean Air Act, is a landmark determination that identifies greenhouse gases as pollutants that endanger public health and welfare. This finding forms the legal basis for numerous climate regulations affecting vehicles,power plants,and other pollution sources.
Why is the EPA Reconsidering the Endangerment Finding?
EPA Administrator Lee Zeldin announced that the EPA would formally reconsider the 2009 Endangerment Finding. Zeldin stated, “The Trump Management will not sacrifice national prosperity, energy security, and the freedom of our people for an agenda that throttles our industries, our mobility, and our consumer choice while benefiting adversaries overseas.” The reconsideration aligns with a broader effort to roll back environmental regulations.
What Greenhouse Gases are Included in the Endangerment Finding?
In 2009, the EPA identified six greenhouse gases that pose a health risk to current and future generations:
Carbon dioxide
Methane
Nitrous oxide
Hydrofluorocarbons
Perfluorocarbons
Sulfur hexafluoride
The EPA also concluded that motor vehicle emissions endanger public health.
What Specific Environmental Rules are Being Rolled Back?
The EPA is initiating a process to repeal or revise 31 environmental rules across various industries. These include regulations related to:
Wastewater discharges for oil and gas extraction facilities
Oil and gas industry reporting through a greenhouse gas program
Rules governing coal ash and coal-fired power plants
National air quality standards for particulate matter
Emission standards for industrial air pollutants
Rules to reduce air pollution that causes haze
Regulations restricting vehicle emissions
What are the Potential impacts of Reconsidering the Endangerment Finding?
Reconsidering the Endangerment Finding could have meaningful consequences:
Weakening of Climate regulations: Eliminating or altering the endangerment finding would allow the EPA to efficiently eliminate significant EPA regulations.
Increased Greenhouse Gas Emissions: Revisions could lead to increased emissions from various industries, perhaps exacerbating climate change.
Impacts on public Health: Relaxing air quality standards and emissions controls could negatively affect public health, especially for vulnerable populations.
Environmental Justice Concerns: Eliminating positions focused on diversity, equity, and inclusion (DEI) and environmental justice raises concerns about equitable protection from environmental hazards.
What are the Arguments in Favor of Reconsidering the Endangerment Finding?
Proponents like EPA Administrator Lee Zeldin argue that the changes will:
Promote national prosperity
Ensure energy security
Protect individual freedoms
Reduce costs for American families
Prevent disadvantaging domestic industries compared to international competitors
What are the Criticisms of the EPA’s Actions?
Climate experts and environmental advocates strongly criticize the EPA’s moves:
Scientific Consensus: Critics argue that the science overwhelmingly supports the endangerment finding and that any contradictory finding would not stand up in court.
Climate Change Denial: Some experts characterize the EPA’s action as a form of climate change denial, minimizing the threat despite scientific evidence. (Michael Mann, climate scientist at the University of Pennsylvania).
* Legal Challenges: Legal experts suggest that the EPA’s effort to strike down environmental protections are likely to face considerable legal challenges. (David Doniger, climate expert at the Natural Resources Defense Council)
Summary of Key Actions and Reactions
| Action | Description | potential Impact |
| :——————————————- | :————————————————————————————————— | :——————————————————————————————————————- |
| Reconsideration of endangerment Finding | EPA will formally review and potentially reverse the 2009 finding that greenhouse gases endanger public health. | Could weaken or eliminate climate regulations; potential for legal challenges. |
