| Year | Month | Milestone | Description |
|---|---|---|---|
| 2023 | December | Initiating Process to Prioritize Five Chemicals for Risk Evaluation Under TSCA | EPA announced that it was beginning the process to prioritize five additional toxic chemicals for risk evaluation under the nation’s premier chemical safety law. If, during the 12-month long statutory process, EPA designates these five chemicals as High Priority Substances, EPA will then begin risk evaluations for these chemicals. More about prioritization. |
| 2023 | December | Issued Draft Risk Evaluation for Flame Retardant TCEP | EPA released its draft risk evaluation for the flame retardant Tris(2-chloroethyl) phosphate (TCEP) for public comment. EPA used the best available science to preliminarily determine that this chemical poses unreasonable risk to human health and the environment. This was the first draft risk evaluation EPA released for the 20 High-Priority Substances prioritized in 2019. |
| 2023 | October | Proposed Ban on Trichloroethylene to Protect Public from Toxic Chemical Known to Cause Serious Health Risks | EPA proposed to ban all uses of trichloroethylene (TCE), an extremely toxic chemical known to cause serious health risks including cancer, neurotoxicity, and reproductive toxicity. TCE is used in cleaning and furniture care products, degreasers, brake cleaners, and tire repair sealants, and a variety of safer alternatives are readily available for many uses. This action would protect people from these health risks by banning the manufacture, processing, and distribution of TCE for all uses. More on TCE. |
| 2023 | October | Proposal to Strengthen TSCA Risk Evaluation Process to Protect Workers and Communities | EPA proposed a rule to strengthen its process for conducting risk evaluations on chemicals under the Toxic Substances Control Act (TSCA). If finalized, the rule would ensure that EPA’s processes better align with the law, support robust evaluations that account for all risks associated with a chemical, and provides the foundation for protecting workers and communities from toxic chemicals. More on the risk evaluation rule. |
| 2023 | September | Requiring Reporting of PFAS Data to Better Protect Communities from Forever Chemicals | EPA finalized a rule under TSCA that will provide EPA, its partners, and the public with the largest-ever dataset of PFAS manufactured and used in the United States. This rule builds on over two years of progress on the Biden-Harris Administration’s action plan to combat PFAS pollution, safeguarding public health and advancing environmental justice, and is a key action in EPA’s PFAS Strategic Roadmap. More on the PFAS reporting rule. |
| 2023 | July | Proposed Workplace Safety Requirements for Carbon Tetrachloride to Protect Worker Health, Fenceline Communities | EPA announced a proposal that will better protect workers from exposure to carbon tetrachloride (CTC), a chemical known to cause serious health risks such as liver toxicity and cancer. This proposal would protect people from these risks by minimizing exposures to workers and communities, while banning uses that have already ceased. More on CTC. |
| 2023 | June | New Framework to Prevent Unsafe New PFAS from Entering the Market | EPA announced its framework for addressing new PFAS and new uses of PFAS. The framework outlines EPA’s planned approach when reviewing new PFAS and new uses of PFAS to ensure that, before these chemicals are allowed to enter into commerce, EPA will undertake an extensive evaluation to ensure they pose no harm to human health and the environment. More on the framework. |
| 2023 | June | Proposed Ban on All Consumer and Many Commercial Uses of Perchloroethylene to Protect Public Health | EPA proposed a ban on most uses of perchloroethylene, a chemical known to cause serious health risks such as neurotoxicity and cancer. The proposal would protect people from these risks by banning all consumer uses while allowing for many industrial/commercial uses to continue only where strict workplace controls could be implemented, including uses related to national security, aviation and other critical infrastructure, and the Agency’s efforts to combat the climate crisis. More about the proposal. |
| 2023 | April | Proposed Ban on All Consumer, Most Industrial and Commercial Uses of Methylene Chloride to Protect Public Health | EPA proposed a ban on most uses of methylene chloride, a dangerous chemical known to cause serious health risks and even death. The proposal would protect people from these risks while allowing for some uses to continue only where strict workplace controls could be implemented to minimize exposures to workers. Methylene chloride was the second chemical to undergo risk management under the reformed process created by the 2016 Frank R. Lautenberg Chemical Safety for the 21st Century Act. More about the methylene chloride proposal. |
| 2023 | February | Proposed Approach for Considering Cumulative Risks under TSCA | EPA released for public comment and peer review a set of principles for evaluating cumulative risks under TSCA and an approach for applying those principles to the evaluation of the cumulative risk posed by certain phthalate chemicals undergoing TSCA section 6 risk evaluation. This was an important step in the process of EPA developing the capability under TSCA to examine risk to people from exposure to multiple chemicals with similar effects. More on the cumulative risk framework. |
| 2023 | January | EPA Finishes Finalizing Revised Risk Determinations | EPA finalized a revision to the TSCA risk determination for trichloroethylene (TCE), finding that TCE, as a whole chemical substance, presents an unreasonable risk of injury to human health when evaluated under its conditions of use. This was the final revision to a risk determination planned as part of the path forward for TSCA risk evaluations announced in June 2021. More on the risk determination. |
| 2022 | November | Supplemental Proposed Fees Rule | EPA issued a supplemental proposed rule modifying and adjusting certain aspects of the fees rule established under TSCA. These changes ensure that collected fees provide the Agency with 25% of authorized TSCA costs consistent with direction in the FY 2022 appropriations bill to consider the “full” implementation costs of the law. Updating TSCA fees strengthens EPA’s ability to successfully implement TSCA in a way that’s both protective and sustainable and significantly improve on-time performance and quality. More about the proposed rule. |
| 2022 | June | First Final Whole Chemical Risk Determination | EPA finalized a revision to the risk determination for cyclic aliphatic bromide cluster (HBCD), finding that HBCD, as a whole chemical substance, presents an unreasonable risk of injury to human health and the environment when evaluated under its conditions of use.
