Time for a new age for new chemicals

NOTE: This is the first of a series about EPA’s regulation of new chemicals.

What Happened?

EPA recently proposed regulations to govern how it reviews companies’ pre-manufacture notifications for new chemicals before those chemicals can go on the market.

Why It Matters

Unfortunately, as we noted in our comments to EPA [PDF, 721KB], the proposal falls significantly short of implementing the fundamental changes needed to ensure the safety of any new chemicals allowed onto the market.

Now’s the Time—How EPA can use TSCA to turn off the PFAS tap

By Maria Doa, PhD, Senior Director, Chemicals Policy / Published: September 18, 2023

Faucet with the word PFAS flowing out of it

In the face of mounting evidence about the dangers posed by per- and polyfluoroalkyl substances (PFAS), one thing is clear: EPA needs to take urgent action to turn off the tap of these “forever chemicals” that have long-term consequences for our health and the environment.

As we discussed in a previous blog, it is imperative that the Environmental Protection Agency (EPA) use the Toxic Substances Control Act (TSCA) to regulate PFAS chemicals comprehensively—both those newly entering the market and those that have been in circulation for decades.

EPA’s approach to 1,4-dioxane falls short of protecting fenceline communities

By Maria Doa, PhD, Senior Director, Chemicals Policy and Paige Varner, PhD, Scientist, Healthy Communities / Published: September 14, 2023

Clear water pouring from a pitcher into a glass.What’s New?

Recently, the Environmental Protection Agency (EPA) embarked on a critical Toxic Substances Control Act (TSCA) supplemental risk evaluation of 1,4-dioxane [PDF, 8.7MB]– a highly carcinogenic chemical that contaminates drinking water supplies across the country and is present in products, such as cleaning supplies and personal care products.

This draft supplemental risk evaluation represents a significant step forward because it addresses many of the omissions from the original 1,4-dioxane risk evaluation. Unfortunately, as we noted in our comments to EPA, a closer examination reveals several shortcomings in how EPA addresses risks to fenceline communities—people living, playing, and working near industrial facilities that release toxic chemicals into the air and water.

New guidelines to inform EPA’s approach to cumulative risk

By Paige Varner, PhD, Scientist, Healthy Communities / Published: September 12, 2023

What’s New?

The Environmental Protection Agency (EPA) recently released and solicited public comments on its draft Cumulative Risk Assessment (CRA) Guidelines for Planning and Problem Formulation. The purpose of a CRA is to determine the combined health and/or environmental risks from multiple stressors and chemicals that can cause the same harms. These guidelines, intended to be applied to all of EPA’s programs and regions, describe how the agency will determine when to use CRAs and the steps it will take to plan them.

Why It Matters

Currently, many EPA programs assess the health and environmental risks of single chemicals, without considering the multiple chemicals that cause the same harms and non-chemical stressors we are exposed to every day. Assessing risks cumulatively, and making regulatory decisions based on this, represents real-world exposures more accurately than single-chemical stressor risk assessments. Read More »

New Approach Methodologies Should Adhere to TSCA Standards

By Susanne Brander, PhD, Senior Contributing Scientist / Published: August 15, 2023

What’s New?

EPA recently asked its Board of Scientific Counselors (BOSC), comprised of experts in the fields of toxicology and environmental chemistry, to make recommendations on implementing new approach methods (NAMs) for testing the safety of new chemicals.

NAMs encompass a wide array of new evaluation strategies, including testing cell lines or invertebrates (rather than mammals); using computational approaches; and estimating potential harms of new chemicals by looking at existing toxicity data on similar substances.

Why It Matters

EPA announced in 2019 that it would be redirecting resources towards developing NAMs to replace those studies. The looming concern is the possibility that NAMs may miss effects that whole animal mammalian testing accounts for and generate false negatives — potentially allowing toxic chemicals to appear in consumer products or end up in our environment.

This could happen because relying only on NAMs or using data from one chemical to predict how a new one might behave opens the door to missing negative effects. NAMs could also cause evaluators to miss opportunities to use the Toxic Substances Control Act (TSCA), the nation’s primary chemical safety law, to limit toxic chemical exposures. Read More »

Fatally Flawed: EDF & partners call on EPA to revoke approval for new chemicals with shocking health risks

By Maria Doa, PhD, Senior Director, Chemicals Policy / Published: August 10, 2023

What Happened?

EDF and other environmental groups recently asked the Environmental Protection Agency (EPA) to withdraw the approval it issued for a group of new chemicals. This approval, also known as a consent order, allows Chevron to create fuels at its refinery in Pascagoula, Mississippi, by using oils produced through a process of superheating plastic waste to break it down (a process known as pyrolysis). The consent order also allows for the use of these fuels derived from waste plastic at more than 100 locations. ProPublica published an article on the issue on August 4, 2023.

Why It Matters

EPA is required by law to provide protections against unreasonable risks posed by new chemicals. But in the consent order EPA approved the production and use of these new chemicals despite significant health risks. One of the chemicals posed a 1 in 4 risk of developing cancer for people exposed to it. Another chemical carried risks of a 7 in 100 cancer risk from eating fish contaminated by it and a greater than 1.3 in 1 cancer risk from inhaling it.

When asked about the shockingly high cancer risks it estimated, EPA claimed its cancer risk assumptions were overly conservative but failed to provide any information about what it believes are the actual risks and pointed to undefined controls under other laws as controlling the risks.

Until now, the acceptable risk standard for cancer in the general population has been 1 in 1,000,000. The risk levels EPA identified are up to 1,000,000 times greater than that. Read More »
