Navigating the Complex World of Toxic Substance Law

Toxic substance law is a critical, multi-layered legal domain designed to protect public health and the environment from the risks posed by chemical substances and hazardous materials. In the United States, this field is primarily governed by federal statutes administered by the Environmental Protection Agency (EPA). For businesses, understanding these regulations is essential for compliance and risk management. For individuals, these laws provide the foundation for seeking justice through toxic tort litigation after suffering harm due to exposure.

This article provides a professional overview of the core legal frameworks—namely the Toxic Substances Control Act (TSCA) and the Resource Conservation and Recovery Act (RCRA)—and examines the elements of a toxic tort case, which often prove to be complex and highly technical.

The Foundational Statute: The Toxic Substances Control Act (TSCA)

The Toxic Substances Control Act (TSCA), enacted in 1976, grants the EPA comprehensive authority to track, test, and regulate chemical substances and mixtures before they enter the stream of commerce. Unlike other environmental laws that focus on pollution cleanup or specific media (air/water), TSCA is a product-oriented law that focuses on the chemicals themselves.

Key Regulatory Components of TSCA

• Inventory and New Chemicals: The EPA maintains the TSCA Inventory, a list of all chemicals manufactured, processed, or imported for commercial purposes. Manufacturers must submit a Premanufacture Notification (PMN) at least 90 days before introducing a “new chemical substance” into commerce.
• Testing Requirements: The EPA can require companies to test chemicals and mixtures for toxic effects where risks or exposures are of concern.
• Regulation and Restriction: TSCA authorizes the EPA to restrict the manufacture, processing, distribution, use, and disposal of certain chemicals, including issuing outright bans. Historically regulated substances include Polychlorinated Biphenyls (PCBs), asbestos, lead, and radon.
• Record-keeping and Reporting: Companies are required to keep detailed records and report any information that reasonably supports the conclusion that a substance presents a “substantial risk” of injury to health or the environment (Section 8(e) reporting).

Substances Excluded from TSCA

It is important to note that TSCA does not regulate all dangerous substances. Several categories are excluded because they are regulated by other federal agencies and statutes:

• Pesticides (regulated by FIFRA)
• Foods, food additives, drugs, cosmetics, or medical devices (regulated by the FDA)
• Tobacco and tobacco products
• Radioactive materials (regulated by the NRC)

Hazardous Waste Management: The Resource Conservation and Recovery Act (RCRA)

Complementing TSCA’s focus on commercial chemicals is the Resource Conservation and Recovery Act (RCRA), which governs the management of hazardous waste. RCRA establishes a comprehensive “cradle-to-grave” system to track and regulate hazardous waste from the moment it is generated until its ultimate disposal.

Under RCRA, regulated entities are divided into categories—Very Small Quantity Generators, Small Quantity Generators, and Large Quantity Generators—with varying levels of compliance requirements. The law mandates strict standards for generators, transporters, and owners/operators of Treatment, Storage, and Disposal Facilities (TSDFs), including detailed record-keeping, personnel training, and contingency plans.

Toxic Tort Litigation: Seeking Compensation for Exposure

When exposure to a toxic substance results in personal injury or property damage, the legal claim falls under the category of a “toxic tort,” a specialized subset of tort law. Toxic tort cases can be pursued by a single individual or by large groups in mass tort or class action lawsuits.

Elements of a Toxic Tort Claim

To succeed in a toxic tort claim, a plaintiff (the injured party) generally must prove four key elements:

1. The Substance Was Dangerous: The plaintiff must show the chemical or material was inherently toxic or unreasonably dangerous.
2. Exposure: The plaintiff must prove they were exposed to the substance (e.g., at work, at home, or through environmental contamination).
3. Injury: The plaintiff must demonstrate a specific, resulting injury or illness.
4. Causation (The Major Hurdle): The plaintiff must prove that the exposure to the defendant’s substance was the direct cause of their specific injury. This often requires complex expert testimony to establish both “general causation” (the substance can harm people generally) and “specific causation” (it harmed this specific plaintiff).

Theories of Liability

A defendant (the responsible party) may be held legally responsible under several legal theories:

• Negligence: This is based on proving the defendant acted in an unreasonably careless manner by breaching a duty of care (e.g., failing to adequately test a product, violating a safety regulation, or improperly releasing chemicals).
• Strict Liability: Often applied in product liability cases, this theory holds manufacturers or suppliers liable if a product (the toxic substance) is proven to be unreasonably dangerous or defective, regardless of whether the defendant acted carelessly.
• Breach of Warranty: A claim that the defendant breached an express or implied promise about the safety or quality of the substance.

Summary: Essential Takeaways for Toxic Substance Law

Key Principles of Toxic Substance Law

1. The primary federal law is the Toxic Substances Control Act (TSCA), which authorizes the EPA to regulate the manufacture, processing, and use of commercial chemicals to prevent unreasonable risk to health and the environment.
2. The Resource Conservation and Recovery Act (RCRA) mandates the strict “cradle-to-grave” management and disposal standards for hazardous waste across all regulated entities.
3. Toxic substance injury claims are brought as Toxic Tort lawsuits, where the plaintiff must prove exposure and a direct, scientifically supported causal link between the toxic substance and their injury.
4. Businesses must maintain meticulous compliance with federal regulations, as adherence to government standards is a key defense against claims of negligence in litigation.
5. The most challenging element in a toxic tort case is proving causation, which often relies heavily on expert testimony from toxicologists and epidemiologists to meet the Daubert standard of scientific evidence admissibility.
