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).

On February 23, 2022, the U.S. Environmental Protection Agency (EPA) held a webinar on requirements under the Toxic Substances Control Act (TSCA) and the premanufacture notice (PMN) process for biofuels. 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. According to EPA, it has received more than 30 biofuel PMNs “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 [Renewable Fuel Standard (RFS)] program and help support the goals of energy security through increasing domestic production” within the United States. Future webinars will cover 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 significant new use rules (SNUR).

The U.S. Environmental Protection Agency will hold a virtual public meeting April 20-21, 2022, to seek individual input on the proposed Toxic Substances Control Act (TSCA) New Chemicals Collaborative Research Program. 87 Fed. Reg. 10784. In addition, EPA announced the availability of and is soliciting public comment on the draft document entitled “Modernizing the Process and Bringing Innovative Science to Evaluate New Chemicals Under TSCA.” EPA states that 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. According to EPA, the effort will be performed in partnership with its Office of Research and Development (ORD) and other federal entities to leverage their expertise and resources. Written comments are due April 26, 2022. Registration for the meeting is now open.
According to EPA, the research program will refine existing approaches and develop and implement new approach methodologies (NAM) 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. According to EPA, 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 exist only in hard copy or in various disparate TSCA databases. EPA will combine the information 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 (CBI) 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. EPA states that 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 integrate more efficiently 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.
EPA states that additional information on each of these areas will be provided in the draft collaborative research plan that will be available in the docket by March 14, 2022. Later in 2022, EPA plans to engage its 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 to open a docket for public comments.
Although the notice states that EPA’s background documents and the related supporting materials to the draft are available in the docket established for this meeting, Docket ID Number EPA-HQ-OPPT-2022-0218, nothing is available at this time. EPA states that it will provide additional background documents as the materials become available. After the virtual public meeting, EPA will prepare meeting minutes summarizing the individual comments received at the meeting. EPA will post the meeting minutes on its website and in the relevant docket.

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.

EPA Office of Inspector General (OIG) announced the availability of its FY 2022 oversight plan on December 14, 2021. According to OIG, the plan reflects the priority work that the OIG believes is necessary to keep EPA, the U.S. Chemical Safety and Hazard Investigation Board (CSB), and Congress fully informed about issues relating to the administration of EPA programs and operations. The planned oversight projects concerning Ensuring the Safe Use of Chemicals include:
- Audit of EPA’s Management of New Chemical Risk Assessments Conducted under TSCA: Determine the extent to which EPA is using and complying with applicable records-management and quality-assurance requirements and employee performance standards to review and approve new chemicals under TSCA to manage human health and environmental risks;
- Evaluation of EPA Regions’ Oversight Responsibilities for State and Tribal Drinking Water Certification Programs: Determine whether select EPA regions are fulfilling oversight responsibilities for drinking water certification programs in states and tribal nations;
- Evaluation of EPA’s Use of Pesticide Incident-Reporting Data: Determine whether EPA uses pesticide incident-reporting data to prevent unreasonable adverse effects on human health and the environment;
- Evaluation of Implementation of EPA’s Federal Certification for Applicators and Dealers of Restricted-Use Pesticides within Indian Country: Determine how EPA monitors and enforces the requirements for restricted-use pesticide applicators (private and commercial) and restricted-use pesticide dealers in Indian Country;
- Evaluation of EPA’s Progress toward Providing States with Clear Benchmarks to Address PFAS in Drinking Water: Determine why EPA has not established a mandatory limit for PFAS in drinking water; what challenges may prevent EPA from setting such a limit; and what EPA’s plan -- if one exists -- is for implementing such a limit; and
- Evaluation of EPA’s Progress to Identify Key Regulatory Stakeholders for TSCA Existing Chemical Risk Management: Determine whether EPA identified and partnered with key regulatory stakeholders and developed a process to coordinate the regulation of occupational exposures from existing chemicals under TSCA.
OIG states that it is important to note that its planning efforts “are not static and that the projects included herein may be modified throughout the year as challenges and risks for the EPA and the CSB evolve and emerge.”

On December 10, 2021, the Biden Administration released its Fall 2021 Unified Agenda of Regulatory and Deregulatory Actions. According to EPA’s rule list, the Office of Chemical Safety and Pollution Prevention (OCSPP) is working on the following rulemakings under the Toxic Substances Control Act (TSCA). Rulemakings at the proposed stage include:
- Tiered Data Reporting to Inform Prioritization, Risk Evaluation, and Risk Management Under TSCA (2070-AK62): EPA is developing this rule to obtain information about potential hazards and exposure pathways related to certain chemicals, particularly occupational, environmental, and consumer exposure information. EPA states that this information is needed to inform prioritization, risk evaluation, and risk management of the chemical substances under TSCA Section 6. EPA intends to publish a notice of proposed rulemaking (NPRM) in July 2022 and a final rule in March 2023. More information on the rulemaking is available in our July 29, 2021, memorandum;
- Revisions to the TSCA Fees Rule (2070-AK64): In January 2021, EPA proposed updates and adjustments to the 2018 TSCA Fees Rule. EPA proposed to add three new fee categories: a Bona Fide Intent to Manufacture or Import Notice, a Notice of Commencement of Manufacture or Import, and an additional fee associated with test orders. In addition, EPA proposed exemptions for entities subject to certain fee triggering activities, including: an exemption for research and development activities; an exemption for entities manufacturing less than 2,500 pounds of a chemical subject to an EPA-initiated risk evaluation fee; an exemption for manufacturers of chemical substances produced as a non-isolated intermediate; and exemptions for manufacturers of a chemical substance subject to an EPA-initiated risk evaluation if the chemical substance is imported in an article, produced as a byproduct, or produced or imported as an impurity. EPA proposed a volume-based fee allocation for EPA-initiated risk evaluation fees in any scenario where a consortium is not formed and proposed to require export-only manufacturers to pay fees for EPA-initiated risk evaluations. EPA states that in light of public comments, it has decided to issue a supplemental proposal and seek additional public comment on changes to the January 2021 proposal. EPA intends to issue a supplemental NPRM in February 2022. EPA has not determined when it will issue a final rule. More information on the proposed rule is available in our December 30, 2020, memorandum;
- New Chemicals Procedural Regulations to Reflect Amendments to TSCA (2070-AK65): This rulemaking seeks to revise the new chemicals procedural regulations in 40 C.F.R. Part 720 to improve the efficiency of EPA’s review process and to align its processes and procedures with the new statutory requirements. According to EPA, this rulemaking seeks to increase the quality of information initially submitted in new chemicals notices and improve its processes “to reduce unnecessary rework in the risk assessment and, ultimately, the length of time that new chemicals are under review.” EPA intends to publish an NPRM in September 2022. EPA has not determined when it will issue a final rule;
- Procedures for Submitting Information Subject to Business Confidentiality Claims Under TSCA (2070-AK68): EPA states that it is considering proposing new and amended rules concerning the assertion and maintenance of claims of business confidentiality (i.e., confidential business information (CBI)) under TSCA. The 2016 TSCA amendments included several new provisions concerning the assertion and EPA review and treatment of confidentiality claims. EPA is considering procedures for submitting and supporting such claims in TSCA submissions, including substantiation requirements, exemptions, electronic reporting enhancements, and maintenance or withdrawal of confidentiality claims. EPA is also considering whether the proposed rule should elaborate on EPA’s procedures for reviewing and communicating with TSCA submitters about confidentiality claims. According to EPA, it expects the proposed rule to include new provisions, as well as revisions to existing rules on asserting confidentiality claims to conform to the 2016 amendments. EPA intends to issue an NPRM in April 2022; and
- Reconsideration of Procedures for Chemical Risk Evaluation Under the Amended TSCA (2070-AK90): EPA published a final rule on July 20, 2017, that established a process for conducting risk evaluations to determine whether a chemical substance presents an unreasonable risk of injury to health or the environment, without consideration of costs or other non-risk factors, including an unreasonable risk to a potentially exposed or susceptible subpopulation, under the conditions of use. This process incorporates the science requirements of the amended statute, including best available science and weight of the scientific evidence. The final rule established the steps of a risk evaluation process, including: scope, hazard assessment, exposure assessment, risk characterization, and risk determination. EPA states that it is now in the process of reconsidering the final rule in keeping with new EOs concerning the advancement of racial equity and support for underserved communities through the federal government (EO 13985), the protection of public health and the environment and restoring science to tackle the climate crisis (EO 13990), tackling the climate crisis at home and abroad (EO 14008), and other Administration priorities (such as the Presidential memorandum on restoring trust in government through scientific integrity and evidence-based policymaking). If EPA determines to amend the 2017 final rule based on its reconsideration, it will solicit public comment through an NPRM. EPA intends to publish an NPRM in September 2022.
The Unified Agenda lists the following TSCA rulemaking at the final stage:
- Significant New Uses of Chemical Substances; Updates to the Hazard Communication Program and Regulatory Framework; Minor Amendments to Reporting Requirements for Premanufacture Notices (PMN) (2070-AJ94): EPA proposed amending components of the Significant New Uses of Chemical Substances regulations at 40 C.F.R. Part 721, specifically the “Protection in the Workplace” (40 C.F.R. Section 721.63) and “Hazard Communication Program” (40 C.F.R. Section 721.72). 81 Fed. Reg. 49598. The proposed changes are intended to align, where possible, EPA’s regulations with the revised Occupational Safety and Health Administration (OSHA) regulations at 29 C.F.R. Section 1910.1200. OSHA issued a final rule on March 26, 2012 (77 Fed. Reg. 17573), that aligns OSHA’s Hazard Communication Standards with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). EPA states that it is reviewing the comments received and is planning to issue a final rule. EPA intends to issue a final rule in September 2022. More information on EPA’s 2016 proposed rule is available in our July 29, 2016, memorandum.

According to an October 26, 2021, project notification memorandum, the U.S. Environmental Protection Agency (EPA) Office of Inspector General (OIG) plans to begin fieldwork on an audit of EPA’s process for conducting reviews of new chemicals under the Toxic Substances Control Act (TSCA). The memorandum states that the audit “is self-initiated based on OIG’s oversight plan for fiscal year [(FY)] 2022 and to address complaints submitted to the OIG Hotline.” The audit also addresses the following FY 2022 top management challenge for EPA: ensuring safe use of chemicals.
OIG states that its objective is to determine the extent to which EPA uses and complies with applicable records management requirements, quality assurance requirements, and employee performance standards to review and approve new chemicals under TSCA to manage human health and environmental risks. OIG plans to conduct work with the Office of Chemical Safety and Pollution Prevention (OCSPP) in EPA headquarters. According to OIG, the anticipated benefits of the audit are “improved operational efficiency and greater human health and environmental protections.”
To expedite the audit, OIG asks that OSCPP provide the following information:
- Any training materials, handbooks, or other materials related to the review of new chemicals;
- Resource allocations for the New Chemicals Review Program for FYs 2018 through 2021;
- Scopes of work for any contracts related to the new chemicals review process;
- Any OCSPP guidance under which products developed during the review of new chemicals would constitute records and how the records should be managed; and
- New Chemicals Review Program organization charts before and after the October 2020 reorganization.
As reported in Bergeson & Campbell, P.C.’s (B&C®) October 28, 2021, memorandum, “House Committee Holds Hearing on ‘TSCA and Public Health: Fulfilling the Promise of the Lautenberg Act,’” Dr. Michal Ilana Freedhoff, OCSPP Assistant Administrator, has let OIG know that OCSPP will cooperate fully with its investigation.
