The U.S. Environmental Protection Agency (EPA) recently introduced a proposed rule that would update the way it evaluates the risks of chemicals already in use under the Toxic Substances Control Act (TSCA).
While this might sound like regulatory housekeeping, the changes could have wide-reaching effects on industries that handle hazardous substances, including manufacturers, laboratories, healthcare facilities and other businesses that generate hazardous waste.
Understanding these proposed revisions is important. They not only influence how chemicals are regulated at the federal level but also determine the responsibilities businesses have when it comes to workplace safety, reporting and waste management.
A Quick Look at TSCA
The Toxic Substances Control Act was first enacted in 1976 and later amended by the Lautenberg Chemical Safety for the 21st Century Act in 2016. Its purpose is to give EPA the authority to review chemicals in commerce and determine whether their use poses an unreasonable risk to human health or the environment.
Over the decades, TSCA has shaped how businesses manufacture, use and dispose of chemicals. Unlike regulations focused only on hazardous waste disposal, TSCA takes a broader view, examining risks across the entire life cycle of a chemical - from production and use to ultimate disposal.
That’s why companies that generate hazardous waste can’t ignore updates to this law. A change in how risks are evaluated often leads to new compliance requirements, operational adjustments or shifts in how certain waste streams must be managed.
What the Proposed Rule Would Change
EPA’s proposed amendments focus on refining its risk evaluation process to make it more efficient, transparent and scientifically robust. Some of the most important changes include:
- Risk determinations by condition of use: Instead of making a single conclusion about whether a chemical is safe or unsafe, EPA would evaluate risk for each specific use of a chemical. For example, a chemical might be considered low-risk in consumer applications but high-risk in industrial settings. This change ensures that risks are not overlooked in particular contexts where exposure may be greater.
- Clearer treatment of occupational exposure: The proposal spells out how EPA will account for workplace protections like personal protective equipment (PPE) and engineering controls. For businesses, this means occupational safety programs could directly influence how risk is determined.
- Discretion over evaluation scope: EPA would have more flexibility in deciding which uses, exposure routes and exposure pathways to include in an evaluation. This may allow the agency to focus on the most pressing risks without being burdened by less relevant scenarios.
- Updated definitions and scientific standards: Several regulatory definitions would be revised to align with executive directives on transparency and “gold-standard” science. For industry, this could bring more clarity about what information EPA expects during evaluations.
- Procedural improvements: The rule proposes new requirements for how EPA revises or supplements its evaluations. These changes are aimed at helping the agency meet statutory deadlines and keep evaluations up to date as new data emerges.
- Manufacturer and importer obligations: Adjustments would also affect how businesses request an EPA-conducted risk evaluation, including refinements to information submission requirements.
Why This Matters for Hazardous Waste Generators
Businesses that generate hazardous waste may not always be directly involved in chemical manufacturing, but they are still subject to TSCA’s influence. Here’s why:
- Changing classifications: If EPA identifies a higher risk associated with a chemical under certain uses, waste streams tied to that chemical could face new disposal requirements. What was once considered routine waste may be reclassified, demanding more stringent handling.
- Compliance risk: Regulations under TSCA are tightly connected with broader hazardous waste laws. Failure to comply with updated standards can expose businesses to fines, legal consequences and reputational damage.
- Operational impact: More detailed risk determinations could lead to changes in workplace practices, training or engineering controls. Companies may need to adjust safety programs or revise their hazardous waste management procedures.
- Proactive planning: By keeping informed about these updates, businesses can better anticipate changes before they become mandatory. This reduces last-minute compliance headaches and helps maintain operational continuity.
Staying Ahead of Regulatory Change
EPA’s proposed rule illustrates the ongoing evolution of chemical management in the United States. For businesses, this means compliance isn’t a static responsibility. It’s something that requires continuous attention. Ignoring these changes can create costly vulnerabilities, while proactive adaptation can strengthen safety and sustainability efforts.
Monitoring EPA’s rulemaking process is one piece of the puzzle. The other is ensuring that your company has reliable systems in place for handling, transporting and disposing of hazardous waste in a way that aligns with current and future regulations.
The Role of a Hazardous Waste Disposal Partner
Navigating shifting regulatory requirements can be challenging, especially when rules like TSCA overlap with other federal, state and local laws. That’s where partnering with a professional hazardous waste disposal company becomes invaluable.
These companies:
- Stay current on the latest EPA rules and guidance
- Provide safe, compliant collection, transportation and disposal of hazardous waste
- Help businesses maintain proper documentation to prove compliance
- Offer expertise in managing complex waste streams that may be subject to evolving definitions or standards
By working with a trusted disposal partner, businesses not only protect themselves from liability but also demonstrate their commitment to safeguarding employees, the community and the environment.
EPA’s proposed revisions to the TSCA risk evaluation process highlight how chemical safety regulations continue to adapt to new science and policy priorities. For businesses that handle hazardous waste, the takeaway is clear: staying informed and proactive is the best defense against compliance risks.
Partnering with a qualified hazardous waste disposal company ensures that waste is managed responsibly, compliance is maintained and your business is ready for whatever changes come next.
