What Was At Stake

Vinyl chloride — a toxic substance used to make plastic — was identified as a known human cancer-causing chemical 40 years ago, yet it has remained in widespread use. It is just now that the U.S. Environmental Protection Agency (EPA) is finally considering designating vinyl chloride as a high-priority chemical under the Toxic Substances Control Act (TSCA).

Supporting this designation is essential to protect our communities and environment from this hazardous substance.

Vinyl chloride exposure significantly increases people’s risk of developing rare liver cancers, as well as other cancers such as brain, lung, lymphoma, leukemia, and other serious health problems. Despite its severe health risks, vinyl chloride remains a key ingredient in polyvinyl chloride (PVC) plastic, which is used to make consumer products like packaging, children’s toys, and building materials.

By designating this toxic substance as a high-priority chemical, EPA will have to conduct a comprehensive risk evaluation and eliminate the chemical’s unreasonable risks. TSCA even gives EPA the authority to ban vinyl chloride, delivering long overdue protections to workers, consumers, and fenceline communities. Public support and advocacy are vital in driving this change to protect public health and the environment from the pervasive threats posed by vinyl chloride.

Ask the EPA today to conduct testing at the tap to determine whether toxic vinyl chloride is leaching from PVC water pipes into our drinking water, visit communities impacted by vinyl chloride pollution, and include the risks from rail or other transportation incidents in its risk evaluation of vinyl chloride.  

Historical usage and disposal of vinyl chloride has led to widespread contamination, particularly at Superfund sites nationwide, where vinyl chloride continues to leach into groundwater. Communities near manufacturing facilities, disposal sites, and transportation routes are at the highest risk of exposure. These often include low-income and marginalized populations already burdened with greater environmental health risks. 

In addition, people are exposed to vinyl chloride as a result of unplanned incidents, including the disastrous 2023 railway crash in East Palestine, Ohio. Between 2010 and 2023, 966 vinyl chloride-related incidents (leaks, spills, fires, and explosions) were reported — an average of one every 5.3 days.

Given the extensive and well-documented harms of vinyl chloride, supporting the EPA’s proposal to designate it as a high-priority chemical is crucial. Send the agency a letter today.

Your Actions Matter

Your messages make a difference, even if we have leaders who don't want to listen. Here's why.

You level the playing field.

Elected officials pay attention when they see that we are paying attention. Read more.

They may be hearing from industry lobbyists left and right, but hearing the stories of their constituents — that’s your power.

Our legislators serve at the pleasure of the people who gave them their job — you.

Make sure your elected officials know whose community and whose values they represent. When you contact your elected official, you’re putting a face and a name on an issue.

Whether or not you voted for them, they work for you, for the duration of their term.

Make sure your elected officials know whose community and whose values they represent. (Find your local, state, and federal elected officials.)

Your action is with us in court.

If a federal agency finalizes a harmful action, the record of public comments provides a basis for bringing them into court. Read more.

Throughout each of the public comment periods we alert you to, Earthjustice’s attorneys are researching and writing in-depth, technical comments to submit — detailing how the regulation could and should be stronger to protect the environment, our communities, and our planet.

We need you to join us — your specific experiences, knowledge, and voice are crucial to add to the Administrative Record through the comment periods.

Lawsuits we file that challenge weak or harmful federal regulations rely on what was submitted during the comment period. The court can only look at documents that are in the Administrative Record — including the public comments — to decide if the agency did something improper.

Your actions aid our litigation. Taking action and submitting comments during a comment period is substantively important.

It’s the law.

Federal agencies must pause what they’re doing and ask for — and consider — your comment. Read more.

Many of us may have never heard of the National Environmental Policy Act (NEPA) and the Administrative Procedure Act (APA), but laws like these require our government to ask the public to weigh in before agencies adopt or change regulations.

Regulations essentially describe how federal agencies will carry out laws — including decisions that could undermine science, or weaken safeguards on public health.

Public comments are collected at various points throughout the federal government’s rulemaking process, including when a regulation is proposed and finalized. (Learn about the rulemaking process.) These comments become part of the official, legal public record — the “Administrative Record.”

When the public responds with a huge outpouring of support for environmental protections, these individual messages collectively undercut politicians' attempts to claim otherwise.

What this means is each of us can take a role in shaping the rules our government creates — and ensuring those rules are fair and effective.
