Engineering Initiative Webinar Series: New Chemical Review Process

Released on October 11, 2022

Join EPA’s New Chemicals Program on October 18th, 2022, from 11 a.m. – 12 p.m. EDT for a webinar on EPA’s process for assessing the potential risks of new chemicals under section 5 of the Toxic Substances Control Act and the types of data the agency considers in this assessment. Specifically, the upcoming webinar will cover examples of quantitative and qualitative data unlikely to be accepted for engineering assessment, considerations EPA makes when evaluating data, and clarifications of common misconceptions in EPA’s new chemical assessments. 

In June 2022, EPA announced a broad outreach effort to describe to stakeholders how the Agency evaluates engineering data (i.e., data related to environmental release and worker exposure) provided for new chemical submissions and common issues that cause EPA to have to reconduct risk assessments (“rework”). The goal of this effort is to prevent delays of EPA’s new chemical reviews caused by rework. 

This is the second in a series of webinars to increase the efficiency and transparency of EPA’s new chemical determinations. In July 2022, EPA hosted the first webinar, analyzing common issues that cause EPA to have to rework risk assessments. Meeting materials are available for those who missed the first webinar.
