The U.S. Environmental Protection Agency (EPA) announced on February 25, 2022, the proposed Toxic Substances Control Act (TSCA) New Chemicals Collaborative Research Program. 87 Fed. Reg. 10784. On March 10, 2022, EPA posted 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) proposes to develop and implement a multi-year collaborative research program focused on approaches for performing risk assessments on new chemical substances under TSCA. On April 26, 2022, the TSCA New Chemicals Coalition (NCC) submitted comments to EPA expressing strong support for EPA’s proposed update to its approach to review and evaluate new chemicals under TSCA Section 5:

  • Research Area 1 -- Update and Refine Chemical Categories: The NCC suggests that EPA develop an Integrated Approach to Testing and Assessment (IATA) for each category, and that the IATA include New Approach Methodologies (NAM) both to set boundaries and to provide a tiered approach for testing;
     
  • Research Area 2 -- Develop and Expand Databases Containing TSCA Chemical Information: The NCC suggests that EPA include robust chemical structure information that is searchable by substructure and Markush representations, as appropriate, in the database. The NCC agrees that using IUCLID and the Organization for Economic Cooperation and Development (OECD) harmonized templates would be an efficient way to curate the data and would contribute to interoperability with other data systems (especially as data are transported from other regions that rely upon IUCLID);
     
  • Research Area 3 -- Develop and Refine Quantitative Structure-Activity Relationship and Predictive Models: The NCC suggests that EPA evaluate whether other existing models may serve EPA’s needs. The NCC also suggests that EPA update E-FAST with additional site-specific stream flows;
     
  • Research Area 4 -- Explore New Ways to Integrate and Apply NAMs: The NCC strongly supports expanding the use of NAMs in the assessment of new chemicals. The NCC also strongly suggests that EPA develop and enforce internal policies about in vivo testing of irritating and corrosive substances;
     
  • Research Area 5 -- Develop a TSCA New Chemicals Decision Support Tool: The NCC supports developing such a decision support tool, but refers EPA to this function within IUCLID. The NCC supports improved transparency on risk assessments and suggests that EPA separate boilerplate explanations of hazard, exposure, and risk from the unique assessment results.

More information on EPA’s draft document is available in our March 14, 2022, memorandum.

As reported in our February 28, 2022, blog item, on February 25, 2022, the U.S. Environmental Protection Agency (EPA) announced that it is revoking the 1980 guidelines and associated procedures for correcting the specific chemical identities of incorrectly described chemical substances submitted to EPA in 1978 using the original reporting form for inclusion on the Toxic Substances Control Act (TSCA) Inventory. 87 Fed. Reg. 10781. On March 25, 2022, the TSCA New Chemicals Coalition (NCC) sent a letter to Michal Ilana Freedhoff, Ph.D., Assistant Administrator of EPA’s Office of Chemical Safety and Pollution Prevention (OCSPP), regarding its concerns with the “phasing out” of the TSCA Inventory correction process. The NCC states that it believes EPA’s decision-making process “would benefit greatly from stakeholder input and urges EPA to suspend the phaseout set to occur on April 26, 2022, and to reconsider the revocation of the 1980 corrections guidelines set to occur May 31, 2022.” According to the NCC, “[‌b]oth decisions invite significant unintended consequences, and stakeholder comment may well provide information that could persuade EPA to go in a different direction.” The NCC urges EPA to address the issues outlined in its letter by suspending its decisions to revoke the guidelines and “phaseout” of the Inventory correction process and seeking comment on its plans.

On March 23, 2022, the U.S. Environmental Protection Agency (EPA) held a webinar on “Biofuel Premanufacture Notices: New Chemical Risk Assessment and Applications of Tools and Models.” As reported in our January 24, 2022, blog item, in January 2022, EPA announced an effort to streamline the review of new biobased or waste-derived chemicals that could displace current, higher greenhouse gas (GHG)-emitting transportation fuels. EPA states that to support this effort, it is offering outreach and training to stakeholders interested in biofuels. According to EPA, the bi-weekly webinar series includes reviewing requirements under the Toxic Substances Control Act (TSCA), outlining the streamlined approaches for risk assessments and risk management actions, and providing information on how to navigate the new chemicals premanufacture notice (PMN) process. EPA provided background and outlined the following challenges for each risk assessment conducted:

  • Chemistry Assessment:
    • Fuel stream and related substances are broad in number and scope, especially with the addition of current biobased and waste feedstock blends; they can be class 1, class 2, or chemical substances of unknown or variable composition, complex reaction products, and biological materials (UVCB) substances;
    • Many petroleum-derived fuel streams are on the original TSCA Inventory and there are very little data associated with them; and
    • Complete characterization of the new chemical substance is often unavailable;
  • Environmental Fate and Transport Assessment:
    • Analysis of constituents may not represent the properties of the new chemical substance;
  • Engineering Assessment: Environmental Releases:
    • EPA’s release assessment analyzes each manufacturing, processing, and use operation and determines the sources/activities that can result in releases to the environment. These release estimates are used to estimate exposure estimates for ecological and human receptors;
    • Examples of release data: (1) Measured release data; (2) Measured release data for a “surrogate” chemical; (3) Modeled release estimates; and
    • Release estimates have limitations -- examples:
      • Lack of appropriate model/method to estimate releases from specific industrial activities (e.g., storage tank emissions); and
      • Limitation in certain release models (e.g., limited to a vapor pressure threshold of 35 torr);
  • Engineering Assessment: Occupational Exposures:
    • The occupational exposure assessment estimates the magnitude, frequency, and duration of exposures to the new chemical substance at the workplace;
    • Worker inhalation and dermal exposures are expected throughout the lifecycle of the new chemical substance (e.g., manufacturing, processing, use); and
    • Exposure models do not account for some engineering controls (vapor capture/reduction);
  • Exposure Assessment: General Population and Consumer Exposures:
    • The occupational exposure assessment estimates the magnitude, frequency, and duration of exposures to the new chemical substance for the general population and consumers via inhalation and drinking water pathways; and
    • The confidence of the exposure estimates are affected by:
      • Assumptions, limitations, and areas of uncertainty in the fate and engineering analyses; and
      • Inherent uncertainties of the exposure parameters and assumptions for the estimation of the general population and consumer exposures;
  • Hazard Assessment:
    • Data on the new chemical substance or an analogous biofuel are preferred, but few submissions include toxicological or composition data;
    • EPA often lacks acute/chronic environmental test data on the new chemical substance and the analogous substances; and
    • There are challenges in performing read-across approaches and route-to-route extrapolations with analogous substances of variable composition.

For biofuel PMNs, EPA has started generating one report that combines the results of each of the above assessments. The final webinar in the series will be held April 6, 2022, on new chemicals risk management actions, including TSCA Section 5 orders and significant new use rules (SNUR).

The U.S. Environmental Protection Agency (EPA) announced on March 4, 2022, the availability of the latest Toxic Substances Control Act (TSCA) Inventory. EPA states that the biannual update to the public TSCA Inventory is part of its regular posting of non-confidential TSCA Inventory data. EPA plans the next regular update of the Inventory for summer 2022. According to EPA, the Inventory contains 86,631 chemicals, of which 42,039 are active in U.S commerce. Other updates include new chemical substance additions, commercial activity data and regulatory flags, such as polymer exemptions, TSCA Section 4 test orders, and TSCA Section 5 significant new use rules (SNUR). EPA notes that on October 15, 2021, it announced a list of 377 specific chemical identities that were expected to lose their confidential status and move to the public portion of the Inventory. According to EPA, these 377 are listed in this public Inventory posting by their specific chemical identities.

On January 21, 2022, the U.S. Environmental Protection Agency (EPA) announced a new effort under the Toxic Substances Control Act (TSCA) to streamline the review of new chemicals that could be used to displace current, higher greenhouse gas (GHG) emitting transportation fuels. The Office of Chemical Safety and Pollution Prevention’s (OCSPP) New Chemicals Division (NCD) has implemented a “robust, consistent, and efficient process to assess the risk and apply mitigation measures, as appropriate, for substitutes to petroleum-based fuels and fuel additives that use biobased or waste-derived sources to produce biofuels.” EPA states that this effort supports its goals under the Renewable Fuel Standard (RFS) program, as well as its 2021 Climate Adaptation Action Plan. According to the announcement, EPA has received over 30 biofuel premanufacture notices (PMN) “that collectively describe plans for close to 800 million gallons per year of production of advanced biofuels, that could contribute to annual volume mandates under the RFS program and help support the goals of energy security through increasing domestic production” within the United States.
 
The announcement includes:
 
New Chemicals Division Integrated Approach to Biofuels
 
Under this effort, NCD formed a dedicated team to collaborate on the review of PMNs for biobased or waste-derived feedstocks used to make transportation fuel substitutes with the goals to use the best available science while creating a consistent and efficient review process. EPA states that NCD developed a standardized process for the way biofuel PMNs are reviewed. For example, the same dedicated team will be conducting reviews for all biofuels PMNs, helping to ensure the assessments and determinations are consistent and aligned with requirements. Further, NCD will generate one report for biofuels PMNs that combines the six different risk assessments typically conducted for PMNs, helping to provide a clearer summary explanation of how EPA conducted its assessment and made its determination.
 
For risk management actions, NCD will apply appropriate mitigation measures to address any potential for unreasonable risk identified in an efficient and consistent manner within TSCA consent orders and significant new use rules (SNUR).
 
Outreach and Training
 
According to the announcement, OCSPP is launching outreach and training for interested stakeholders in the biofuels sector to review TSCA requirements, outline the streamlined approaches for risk assessments and risk management actions, and provide information on how to navigate the new chemicals PMN process.
 
OCSPP will hold a kick-off meeting on February 9, 2022, to provide an overview of this initiative and answer questions from stakeholders. Registration for the meeting is open.
 
Other planned outreach and training related to this biofuels initiative include webinars on:

  • TSCA requirements and the PMN process;
  • The TSCA Inventory, nomenclature, and Bona Fide process;
  • New chemicals risk assessments, including applications of the tools, models, and databases; and
  • New chemicals risk management actions, including TSCA Section 5 orders and SNURs.

EPA states that it may add additional outreach and training sessions, including training opportunities applicable to all new chemical submitters, based on stakeholder interest and feedback.

The U.S. Environmental Protection Agency (EPA) announced on April 27, 2021, “important policy shifts in its review of new [per-and polyfluoroalkyl substances (PFAS)] before they can enter the market.”  According to EPA, although some new PFAS have been allowed to enter the market through low volume exemptions (LVE), EPA’s New Chemicals Program is implementing a new strategy for reviewing and managing LVE requests for PFAS.  EPA states that due to the scientific complexities associated with assessing PFAS, and the hazard potential associated with various sub-classes of PFAS, “it is challenging to conduct an appropriately robust review of LVE requests for PFAS in the 30 days the regulations allow.”  Under the regulations, EPA can deny LVE requests if it finds the chemical may cause serious human health effects or significant environmental effects or when issues concerning toxicity or exposure require review that cannot be completed in 30 days.  According to EPA, “[g]iven the complexity of PFAS chemistry, potential health effects, and their longevity and persistence in the environment, an LVE submission for a PFAS is unlikely to be eligible for this kind of exemption under the regulations.”  While EPA will consider each LVE application individually, it “generally expects” that it will deny pending and new LVE submissions for PFAS.  This will allow EPA more time to conduct a more thorough review and, as appropriate, “put measures in place to mitigate the potential risk of these chemicals as the agency determines whether to allow them to enter commerce.”  EPA states that in addition, it is “exploring ways to work cooperatively with companies to voluntarily withdraw previously granted LVEs.”  EPA states that this “would build upon a 2016 outreach effort that resulted in companies withdrawing more than half of the 82 long-chain PFAS LVEs that existed at the time.”
