TSCA Risk Evaluation Consortium

1, 3-butadiene was identified as a high-priority candidate chemical for TSCA risk evaluation. It is important to note that a designation of 1, 3-butadiene as a high-priority chemical “does not constitute a finding of risk” and should not be cause for concern. A high-priority designation simply means the EPA has nominated 1, 3-butadiene for further risk evaluation.

What This Means for Your Business

The TSCA risk evaluation process will focus on the lifecycle of the chemical substance. If EPA’s TSCA risk evaluation identifies conditions of use of 1, 3-butadiene that present an unreasonable risk, EPA will be required to evaluate and implement risk management options associated with those applications. This could result in changes in how 1, 3-butadiene can be utilized in various applications.

Additionally, the result of EPA’s risk evaluation may also lead to modifications on permitting, procurement, and regulatory requirements at the federal and state level.

How Much a TSCA Risk Evaluation Costs

Manufacturers and importers of 1,3-butadiene will be required to equally share payment of a $1,350,000 fee for EPA to conduct the risk evaluation.

About the 1,3-Butadiene TSCA Risk Evaluation Consortium

For years, several producers, suppliers, and users of 1, 3-butadiene and 1, 3-butadiene products, have organized as members of the ACC Olefins Panel to conduct scientific research, regulatory and legislative advocacy, and educational outreach. The Olefins Panel has invested millions of dollars in conducting and communicating scientific research. This work has provided critical information for regulatory and scientific policy decision-making in the U.S. and abroad.

It is critical stakeholders continue these efforts and play an active role in the TSCA risk evaluation process and maximize all the opportunities to provide input to EPA. In an effort to share costs and promote efficiency, 1, 3-butadiene stakeholders have formed a consortium to collaborate on the development of comments and generate relevant data and information to inform the EPA TSCA risk evaluation.
