EPA’s Webinar for New Chemicals Program

EPA’s Webinar for New Chemicals Program

The U.S. Environmental Defense Agency’s (EPA) New Chemicals System held a webinar on July 27, 2022, to give an in-depth glimpse at its analysis of common problems that cause EPA to have to reconduct risk assessments (“rework”) of new chemical substances. As claimed in our June 27, 2022, memorandum, in June 2022, EPA introduced a broad outreach effort and hard work to describe and to examine with stakeholders how EPA evaluates engineering information (i.e., data linked to environmental launch and worker publicity) furnished for new substances submissions below the Toxic Substances Regulate Act (TSCA) and popular difficulties that induce EPA to have to rework threat assessments for these submissions. EPA has posted the conference slides online.

In accordance to EPA, when a business amends its submission right after EPA’s critique process has started, the additional info may well be supposed to:

EPA states that for small quantity exemptions (LVE), “companies sometimes post a next or 3rd submission for the exact [new chemical substance (NCS)] that was earlier denied by EPA.”

To have an understanding of the common also submitted info producing most of the rework to EPA’s engineering evaluation, EPA analyzed 94 distinctive circumstances with added information and facts submissions that ended up originally submitted from 2019 to 2022. For each and every case, EPA reviewed the business submissions to determine the kind of details submitted. EPA then compared that data to distinct variations of the engineering assessment to determine regardless of whether the added facts resulted in revisions to EPA’s assessment and recorded how many occasions each scenario was revised. EPA reviewed, compiled, and catalogued the gathered information into key “bins” related to environmental launch and occupational publicity. EPA then broke each individual major bin into sub-bins “to establish perception into far more distinct will cause of rework.”

All through the webinar, EPA introduced an illustration of a rework case. In accordance to EPA, from its examination, it observes that:

  • Facts on materials harmony parameters, environmental releases, environmental launch media, and engineering controls lead to virtually 80 percent of all rework

  • In most conditions, businesses give further details that deviates from EPA design defaults and assumptions and

  • Organizations normally lack being familiar with on what data is essential for a Portion 5 engineering assessment, together with the degree of detail necessary to support their statements relating to environmental release and employee publicity.

As noted in the conference slides, EPA designs to keep two further webinars in drop 2022 that will protect:

  • How EPA evaluates quantitative and qualitative facts, with illustrations on the amount of depth desired to assistance the submitted information and facts to be recognized by EPA and

  • The styles of information and facts frequently missing in Segment 5 submissions, how EPA evaluates environmental launch data on sites not controlled by the submitter, and their impression on engineering evaluation.

The webinar integrated a problem and remedy (Q&A) interval. EPA mentioned that it ideas to use examples from real circumstances in the following webinar. EPA will redact any confidential small business information and facts (CBI) and search at how handy the circumstance is soon after the redaction. EPA may need to have to edit the situation to make it distinct to stakeholders. When asked how many of the rework submissions were requested by EPA, EPA responded that it does not request rework. According to EPA, when organizations make a submission, it would be helpful to include the amount of industrial sites, and even receiving a array would be extra useful than leaving the information blank. EPA is familiar with that it can be complicated to detect the variety of buyer works by using, but if companies have that information, it could be advantageous to give it. EPA understands that it can be tough to estimate. EPA stated that corporations normally improve the creation quantity if they turn out to be conscious that the first quantity would consequence in an unreasonable threat dedication. EPA is considering revising its directions to ensure better information and facts in original filings.


EPA’s webinar proceeds its work to supply submitters with far more info to support in planning preliminary submissions. Bergeson & Campbell, P.C. (B&C®) has prolonged been of the look at that premanufacture notices (PMN) ought to be accompanied by strong information and facts. TSCA reform has produced it even more significant. This webinar extends EPA’s attempts to garner extra information, but other than the breakdown of why instances are reworked, the webinar fell small on offering further steerage in this regard that was not presently obtainable in EPA’s nicely-written Details to Take into account document.

We would welcome EPA supplying steerage on what justification or basis is essential to persuade EPA not to use its default assumptions above true knowledge. A single of the EPA presenters proposed that EPA will tackle this situation in a person of the subsequent webinars, which would be beneficial new details. It is also even now not crystal clear what, if any, difference additional information may well have on EPA’s regulatory conclusions, in specific, what conditions of use are moderately foreseen. In our encounter, facts submitted with a PMN or LVE would seem principally to notify EPA’s look at on the intended ailments of use, not the recognized or fairly foreseen situations of use. EPA deferred answering queries linked to regulatory results during the Q&A time period. We glimpse ahead to the upcoming webinar in this sequence.
