EPA Reroutes a “Path Forward” for TSCA Chemical Risk Assessments

In response to recent Executive Orders issued by President Biden, the U.S. Environmental Protection agency recently announced that it will be changing how it evaluates chemical risk under the Toxic Substances Control Act (TSCA). These changes will affect risk evaluations going forward, as well as 10 chemicals already evaluated by the EPA under the last administration. The EPA stated that the policy change is meant to ensure the public is protected from unreasonable risks from chemicals in the marketplace while relying on support that is …

Third Circuit Affirms No Duplicative Reporting for “Federally Permitted Releases”

Two fires at the U.S. Steel Mon Valley Works facility near Pittsburgh, PA in December 2018 and 2019 resulted in the release of pollutants, including hydrogen sulfide, benzene, and coke oven gas into the air. Following air monitoring that revealed increased levels of the pollutants, in compliance with its Clean Air Act permits and regulations, U.S. Steel reported the fires and emissions to the Allegheny County Health Department—the local governmental arm that enforces the Clean Air Act.

Notwithstanding, the Clean Air Council, a nonprofit environmental …

Renewable Fuels Association et al., the Supreme Court of the United States (SCOTUS) sided with the oil refineries in a dispute with biofuel producers. The ruling overturned a Tenth Circuit decision that voided extensions of waivers from the Renewable Fuel Standard (RFS) requirements under the Clean Air Act granted by the United States Environmental Protection Agency (EPA), even though the prior exemptions had expired.

It’s About Time—New York PSC’s New Approval Timeline

Historically, the process to complete large scale utility projects has gone at a deliberate pace. Beyond the traditional issues with any new construction or large scale project, delays were attributed to the extended approval process required by the New York Public Service Commission (PSC). However, on April 3, 2020, New York Gov. Andrew Cuomo signed into law the Accelerated Renewable Energy Growth and Community Benefit Act, which “aimed at improving the siting and construction of large-scale renewable energy projects in an environmentally responsible and cost-effective …

Environmental Disclosures: This Looks Like a Job for … the SEC?

$600 Billion. That is the amount of money directly attributed to weather events brought on or exacerbated by climate change over the past five years. Now a coalition of states, including Connecticut, Delaware, Illinois, Maryland, Michigan, Minnesota, New York, Oregon, Vermont, and Wisconsin, and led by California (the Coalition), are pushing for the U.S. Securities and Exchange Commission (SEC) to require U.S. companies to disclose their financial risks posed by climate change.

As stated in a press release by California Attorney General Rob Bonta, “Rising temperatures are …

Dairy Milk, Farms, and PFAS—Issues Recently Highlighted in Hearing Before SAAS

Dairy farmers—particularly in Maine, but in the Midwest as well—have recently made headlines because of alleged PFAS contamination on farms and in dairy milk. The U.S. senators from Maine are bringing to light farm contamination in their states, and it is likely to gain traction in other agriculture-heavy jurisdictions, particularly the Midwest.

“Over the past several years, we have seen family farms in Maine affected by PFAS. In 2016, a dairy farmer in Arundel, Maine, discovered that the milk produced on his farm contains some …

The EPA’s Campaign to Transform WOTUS from Ephemeral to Resolute

If we are being honest, when it comes to the Clean Water Act, “navigable” is just one of those words that makes us all a bit tongue tied—not just because it’s tricky to pronounce, but because it is even more vexing to define, especially when we look to make sense of the regulatory definition of “waters of the United States.” Unpacking the definition of navigable and federally protected waters has indeed been the perennial work of scholars, judges, lawyers, and politicians alike since the CWA’s …

Can “Microrobots” Help Humans Battle Microplastics Pollution?

The presence of microplastics—fragments of plastic smaller than 5 millimeters—is ever increasing across all types of environments, from cities to waterways. Moreover, microplastics do not biodegrade easily; the process can take hundreds of years. The ubiquity of durable microplastics in our environment, and the challenges we face in removing them due to their small size, has resulted in a significant amount of research intended to assess the ways by which microplastics can be eliminated.

A recent study in ACS Applied Materials & Interfaces is the …

Air Quality Control Board Votes to Cut Emissions in Southern California

Southern California is known for its beautiful beaches, perfect weather, and for being the smoggiest region in the nation.

The Warehouse Rule is essentially a program that will focus on reducing the exposure of nitrogen oxide and diesel particulate matter in the air over the next three years. Specifically, the Warehouse Rule …
