Environmental Protection Agency Administrator Lee Zeldin revealed nearly 30 changes to regulations intended to alleviate industry burdens and boost the economy. These changes would impact key regulations aimed at safeguarding air and water quality. While industry welcomed the proposals, environmentalists expressed concerns over potential significant rollbacks. Some of the changes include reevaluating emissions standards for power plants, revisiting toxic emission limits, and reviewing wastewater rules for power plants. Additionally, the agency plans to explore new applications for oil and gas wastewater and reassess emergency planning for petrochemical facilities. The EPA is also reconsidering greenhouse gas reporting requirements.
The Environmental Protection Agency (EPA) is reevaluating its mandatory program for reporting greenhouse gas emissions, which requires major industrial polluters to disclose their emissions data to the agency. This program has been criticized by some for its high cost and perceived lack of impact on air quality. The EPA has traditionally used this data to help businesses compare their emissions with competitors, identify opportunities for emission reductions, and minimize costs.
There is a call to review the regulations concerning light-duty, medium-duty, and heavy-duty vehicles, with a specific focus on emissions standards. These standards are seen as the cornerstone of the Biden-Harris administration’s push for electric vehicles. While the administration has not mandated automakers to produce or consumers to purchase electric vehicles, stricter standards have been seen as driving innovation in vehicle efficiency.
Another area under scrutiny is the 2009 Endangerment Finding, a scientific determination made under the Clean Air Act that recognizes the threat of greenhouse gases to public health and welfare. Revisiting this finding could have serious implications for the nation’s efforts to combat climate change and protect human health and the environment.
Additionally, the EPA is considering changes to the technology transition rule aimed at reducing the use of hydrofluorocarbons (HFCs), powerful greenhouse gases used in various appliances. Many countries have committed to reducing HFC usage, and this rule has played a significant role in curbing their impact on the environment.
The EPA is also contemplating ending the ‘Good Neighbor Plan,’ which aims to reduce air pollution from power plants and industrial sources across multiple states. While this rule has faced legal challenges and criticism, its elimination could have consequences for communities affected by pollution.
A reevaluation of the Science Advisory Board and Clean Air Scientific Advisory Committee is being considered, given their importance in shaping environmental policies. These bodies provide crucial scientific advice to the EPA Administrator on various aspects of environmental regulation and research.
Lastly, the EPA is reassessing the National Ambient Air Quality Standards for particulate matter, or soot, emitted by industrial sources. Tightening these standards has been supported by scientific evidence indicating the need for stronger regulations to protect public health.
To prevent numerous cases of asthma and missed workdays each year, the EPA regulations established during the Trump administration are under scrutiny. The administration believes these rules pose significant challenges for companies and argue that the levels of soot in the U.S. are already low. There is a call to reassess the national emission standards for air pollutants in the energy and manufacturing sectors, as these standards target chemicals that are linked to cancer, birth defects, and other serious health issues. Industrial facilities are mandated to adhere to strict guidelines for monitoring and controlling the release of these harmful substances into the atmosphere. Recently, the EPA tightened regulations on ethylene oxide emissions, a known carcinogen used for sterilizing medical equipment. The Trump administration is contemplating a potential “2-year compliance exemption” for facilities impacted by these regulations.
The Regional Haze Program, a long-standing EPA initiative, has been instrumental in reducing pollution that obstructs the scenic beauty of over 150 national parks and wilderness areas, such as the Grand Canyon and Yellowstone. Critics argue that this program is being misused to shut down industrial operations and jeopardize affordable energy sources.
Another crucial aspect being reexamined is the ‘Social Cost of Carbon,’ a tool used by the EPA to evaluate the economic ramifications of regulating industries that emit carbon dioxide, a key contributor to climate change. Under the Biden administration, this cost is set at $190 per ton, compared to around $5 per ton during the previous Trump administration. There are discussions about potentially eliminating this calculation altogether to align with Trump’s energy policy objectives.
Efforts are also being made to streamline the coal ash program by expediting state permit reviews and updating regulations. Coal combustion produces ash containing hazardous substances like arsenic, lead, and mercury, which are typically stored in large pits under federal oversight. The EPA is now pushing for greater state involvement in regulating coal ash disposal, a move that has raised concerns among environmental advocates about potentially weakening standards.
