A Modern-Day Gold Rush – World’s Largest Lithium Mine Discovered in Nevada

A lithium mine has been discovered within the McDermitt Caldera, located along the Nevada-Oregon border. This finding is significant in that it may hold between 20 million and 40 million metric tons of this rare metal, which is nearly double the current record of approximately 23 million metric tons of lithium found this summer beneath a Bolivian salt flat. To put the magnitude of this finding further into perspective, the McDermitt Caldera is approximately 28 miles long and 22 miles wide.

Lithium is a chemical …

The Un-wilding of Wildfires: How We Have Added Fuel to the Flames

In their purest form, natural wildfires, most commonly caused by lightning strikes or volcanic activity, are a necessary part of the lifecycle in most ecosystems. They provide a number of important ecological benefits, such as reducing dead vegetation, stimulating new growth, and improving wildlife habitat. Indeed, a variety of plant and animal species depend on wildfires for their very survival.

However, in recent years, numerous countries, including the United States, have experienced significant wildfires that have moved far beyond these ecological benefits, leaving entire communities …

EPA Revises Carbon Tetrachloride Risk Determination to Protect Worker Health and Fenceline Communities

Carbon tetrachloride (CTC) is a solvent used as a raw material in commercial settings to produce chemicals such as hydrofluoroolefins for refrigerants, aerosol propellants, foam-blowing agents, chlorinated compounds, and agricultural products.

Notably, the U.S. Consumer Product Safety Commission banned the use of CTC in consumer products in 1970. Additionally, in 1996, CTC was phased out from production in the United States for most domestic uses that did not involve manufacturing other chemicals as a result of requirements under the Montreal Protocol and the Clean Air …

EPA’s New Renewable Fuel Standards Add Biofuel to the Fire

The Environmental Protection Agency issued its final rule establishing biofuel volume requirements for 2023 to 2025 under the Renewable Fuel Standard (RFS) program on June 21. The Rule aims to reduce the United States’ reliance on foreign sources of oil by approximately 130,000 to 140,000 barrels of oil per day by requiring annual volumes of renewable fuels to be used in the fuel supply. While the EPA boasts that the rule reflects its ongoing efforts to “ensure stability of the program for years to come, …

Using Technology to Turn the Tide on Climate Change

A 2022 Interagency Sea Level Rise Technical Report, authored by various governmental agencies, found that global mean sea levels could rise between one and seven feet by 2100.  This would me significant impacts to the more than 40 percent of Americans who live near coastal waters. Coastal flooding can have major impacts to infrastructure, such as roads and homes, as well as many other impacts to human health. For example, rising sea levels can also threaten hazardous waste facilities, such as landfills, that are located …

Pitching the Plastic: A Call to Reduce Plastic Pollution

On the eve of Earth Day, the Biden Administration announced a new “White House Interagency Policy Committee (“IPC”) on Plastic Pollution and a Circular Economy.” The IPC is tasked with coordinating federal efforts on plastic pollution, prioritizing public health, economic development, environmental justice, and equity to ensure that the benefits of acting on plastic pollution are available to all.

Alongside the IPC, the Environmental Protection Agency also released a draft “National Strategy to Prevent Plastic Pollution” for public comment, which seeks to eliminate the release …

New Year, New WOTUS: Is There Resolution in Sight?

The Environmental Protection Agency’s and Army Corps of Engineers’ “Revised Definition of ‘Waters of the United States’”(WOTUS) rule will become final on March 20. This latest iteration codifies the agencies’ pre-2015 approach to defining WOTUS and attempts to establish a bridge between the interpretations offered by the prior two administrations. In particular, the rule’s preamble specifically states that in “developing this rule, the agencies considered the text of the relevant provisions of the Clean Water Act and the statute as a whole, the scientific record, …

Advancing Environmental Justice: EPA Releases New Roadmap to Address Cumulative Impacts

The Environmental Protection Agency recently published a Cumulative Impacts Addendum (“Addendum”) to its Legal Tools to Advance Environmental Justice (“EJ Legal Tools”), issued in May 2022. 

This Addendum builds on the cumulative impacts discussion in the EJ Legal Tools and provides additional detail and analysis regarding the EPA’s legal authority to address cumulative impacts affecting communities with environmental justice concerns.[1] These authorities include standard-setting, permitting, cleanup, emergency response, funding, planning, and state program oversight.

Although the Addendum itself is not a legally …

Outsmarting Climate Change: Artificial Intelligence and the Future of Greenhouse Gas Regulation

For nearly a decade, there has been a trend of decreasing industry greenhouse gas (GHG) emissions … that is, until now. According to the World Meteorological Organization, atmospheric levels of the three main greenhouse gases—carbon dioxide, methane, and nitrous oxide—all reached new record highs in 2021. In addition, these emissions have increased almost an additional 1% in the United States for 2022. Although the reason for this increase is not entirely clear, it is likely the result of both biological and human-induced processes, including a …
