News Brief

Recently, the U.S. Senate Committee on Environment and Public Works (EPW) held a legislative hearing to examine the draft of The Toxic Substances Control Act (TSCA) Fee Reauthorization and Improvement Act. This draft targets the operational core of the U.S. new chemical regulatory framework, proposing a strategic overhaul to rectify the protracted inefficiency and lack of transparency currently plaguing the EPA’s review process.

Reform Background

Despite the 2016 Lautenberg Act's attempt to modernize the 1976 Toxic Substances Control Act, EPA’s new substance evaluation pipeline has failed to achieve optimal throughput. The current environment is characterized by unpredictable timelines and escalating compliance costs: 90.2% of Pre-Manufacture Notices (PMNs) now exceed the statutory 90-day window, with 66.8% remaining unresolved for multiple years. Furthermore, the ambiguous interpretation of standard have led the EPA to default to restrictive mandates, even for low-risk innovations intended to phase out legacy toxins.

Key Reform Measures Proposed for the TSCA New Chemical Review Process

To address administrative stagnation, the discussion draft proposes several structural initiatives to build a safe yet efficient review mechanism:

Establishing Clear Rules to Enhance Predictability

• Defining Legal Standards: The draft requires the definition of key terms governing risk assessment to clarify the EPA's legal review standards, reducing uncertainty caused by excessive discretionary power.

• Pre-emptive Compliance Guidance: EPA is tasked with issuing explicit "completeness" criteria, ensuring applicants can provide all required data upfront and avoiding the cycle of iterative information requests.

• Strengthening the Sustainable Future Program: By training submitter to master the EPA’s screening models, the draft ensures that industry and regulators use the same toolkit, resulting in faster, more transparent, and consistent reviews.

Scientific Tiering and Resource Optimization

• Four-Tier Review System: The draft proposes reallocating resources into four review tiers. By pre-classifying substances based on chemical category and properties, mature and well-understood risks can be moved to a "fast track," allowing EPA to focus on truly challenging, novel chemicals.

• Introduction of Third-party Assessor: The draft allows third-party assessment bodies to conduct preliminary data reviews to accelerate the overall process.

Establishing a Stewardship Pathway

The bill allows manufacturers to conduct front-end assessments based on EPA-approved methodologies and commit to rigorous supply chain management obligations. Under this pathway, EPA’s review remains locked on the "intended use" stated in the filing, preventing regulators from indefinitely delaying reviews by speculating on "limitless possible alternative uses." 

Regulatory Outlook: A Regulatory Turning Point for TSCA New Chemical Reviews

This draft signals a fundamental shift in the U.S. regulatory philosophy: moving away from a model of "default obstruction" toward a "risk-calibrated entry" system. 

The current operational breakdown is fueled by a dual crisis: vague legal standards and a significant "brain drain" within EPA. This has turned the new substance evaluation process into a "black box" of indefinite delays.

Ultimately, achieving a breakthrough will require a robust bipartisan effort. The primary legislative vehicle for these reforms is the TSCA Fees Re-authorization, a high-stakes mandate that must be finalized by October 1, 2026. This deadline creates a critical window of opportunity for structural change.
