# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Notice.

# SUMMARY:

The Environmental Protection Agency (EPA) is holding a virtual public meeting to seek individual input on the proposed Toxic Substances Control Act (TSCA) New Chemicals Collaborative Research Program. This virtual meeting will be held over 2 half days. In addition, EPA is announcing the availability of and soliciting public comment on the draft document entitled “Modernizing the Process and Bringing Innovative Science to Evaluate New Chemicals Under TSCA.” The Office of Chemical Safety and Pollution Prevention (OCSPP) is proposing to develop and implement a multi-year collaborative research program focused on approaches for performing risk assessments on new chemical substances under TSCA. This effort will be performed in partnership with the Agency's Office of Research and Development (ORD) and other federal entities to leverage their expertise and resources. The results of the effort are expected to bring innovative science to new chemical reviews, modernize the approaches used, and increase the transparency of the information underpinning the human health and ecological risk assessment process.

## II. Background

### A. What is the proposed TSCA New Chemicals Collaborative Research Program?

OCSPP is proposing to develop and implement a multi-year collaborative research program focused on approaches for performing risk assessments on new chemical substances under TSCA. This effort will be performed in partnership with ORD and other federal entities to leverage their expertise and resources. The results of the effort are expected to bring innovative science to new chemical reviews, modernize the approaches used, and increase the transparency of the human health and ecological risk assessment process.

This research program will refine existing approaches and develop and implement new approach methodologies (NAMs) to ensure the best available science is used in TSCA new chemical evaluations. Key areas proposed in the TSCA New Chemicals Collaborative Research Program include:
    - Updating OCSPP's approach to using data from structurally-similar chemicals to determine potential risks from new chemicals, also known as read-across. This will increase the efficiency of new chemical reviews promoting the use of the best available data to protect human health and the environment.
    - Digitizing and consolidating information on chemicals to include data and studies that currently only exist in hard copy or in various disparate TSCA databases. The information will be combined with publicly available sources to expand the amount of information available, enhancing chemical reviews and enabling efficient sharing of chemical information across EPA. Safeguards for confidential business information will be maintained as appropriate in this process.
    - Updating and augmenting the models used for predicting a chemical's physical-chemical properties and environmental fate/transport, hazard, exposure, and toxicokinetics, to provide a suite of models to be used for new chemicals assessments. The goal of this effort is to update the models to reflect the best available science, increase transparency, and establish a process for updating these models as science evolves.
    - Exploring ways to integrate and apply NAMs in new chemicals assessments, reducing the use of animal testing. As this effort evolves, the goal is to develop a suite of accepted, fit-for-purpose NAMs that could be used by external stakeholders for data submissions under TSCA as well as informing and expanding new chemical categories.
    - Developing a decision support tool that integrates the various information streams specifically used for new chemical risk assessments. The decision support tool will more efficiently integrate all the data streams ( e.g.,                      chemistry, fate, exposures, hazards) into a final risk assessment and transparently document the decisions and assumptions made. Simply put, this will facilitate the new chemicals program tracking decisions over time and evaluating consistency within and across chemistries.                

Additional information on each of these key areas will be provided in draft collaborative research plan that will be available in the docket in by March 14, 2022.

### B. How is EPA seeking public comments?

EPA is seeking public comments through several planned activities including:
    - Through this Federal Register                      Notice, EPA is announcing it intends to have a virtual public meeting on April 20 and 21, 2022, to seek individual input from the public on the proposed TSCA New Chemicals Collaborative Research Program. The agenda and instructions for registration for this meeting will be added to the EPA website and public docket March 14, 2022.                
    - At the same time, EPA will launch the website for this collaborative research program. EPA intends to make the collaborative research program document and charge questions available during the week of March 14, 2022 and will issue a listserv to alert the public when these documents become available. The date the documents are added to the docket will start the official 60 days public comment period.
    - Following the virtual public meeting, EPA intends to update the draft collaborative research program document as appropriate, and will place the document in the relevant docket, ID number EPA-HQ-OPPT-2022-0218.
    - Later in 2022, the Agency is planning to engage the EPA's Board of Scientific Counselors (BOSC), a federal advisory committee, for peer review; EPA also intends to issue a Federal Register                      Notice announcing the BOSC meeting and open a docket for public comments.                
    - EPA intends to solicit public comment at various points in the development and implementation of the collaborative research program, and       ( print page 10786)      
    - Conduct additional outreach to external stakeholders through a variety of mechanisms as appropriate, to receive input and enhance transparency.

### C. How can I access the documents?

                    EPA's background documents and the related supporting materials to the draft are available in the docket established for this meeting at                     *https://www.regulations.gov;*                     docket ID number EPA-HQ-OPPT-2022-0218. In addition, EPA will provide additional background documents as the materials become available. You may obtain electronic copies of these documents, and certain other related documents that might be available, in the docket at                     *https://www.regulations.gov.*
