The U.S. Environmental Protection Agency (EPA) announced on February 23, 2023, that the New Chemicals Program will hold a webinar on February 28, 2023, on EPA’s process for assessing the potential risks of new chemicals under Section 5 of the Toxic Substances Control Act (TSCA) and the types of data EPA considers in this assessment. EPA states that specifically, the upcoming webinar will cover commonly missed information in Section 5 submissions and how EPA evaluates environmental release information for operations that occur at non-submitter sites. Registration is now open.
 
As reported in our June 27, 2022, memorandum, in June 2022, EPA announced outreach to describe how it evaluates engineering (i.e., environmental release and worker exposure) data for new chemical submissions and common causes of EPA having to reconduct risk assessments (i.e., “rework”). The goal of this effort is to prevent delays of EPA’s new chemical reviews caused by rework.
 
The February 28, 2023, webinar is the third and final webinar in a series to increase the efficiency and transparency of EPA’s new chemical determinations. The first two webinars, held in July and October 2022, focused on common issues that cause EPA to rework risk assessments, clarifications of common misconceptions in EPA’s new chemical assessments, and other information related to TSCA Section 5 submissions. More information on these webinars is available on EPA’s website and in our July 28, 2022, and October 25, 2022, memoranda.

On November 21, 2022, the U.S. Environmental Protection Agency (EPA) announced that it has improved public access to certain reports submitted by chemical companies in ChemView, EPA’s web application for public access to non-confidential business information (non-CBI) on chemicals regulated under the Toxic Substances Control Act (TSCA), including new chemical notices and notices of substantial risk. EPA has published previously unpublished new chemical notices received under TSCA Section 5 and notices of substantial risk provided by companies under TSCA Section 8(e). EPA states that going forward, it will continue to identify older, previously submitted unpublished information to make available in ChemView and will publish newly received TSCA Section 5 notices and TSCA Section 8(e) reports on a “near real-time basis.” EPA has also published in ChemView chemical health and safety studies received under TSCA Section 8(d).
 
New Chemical Submissions
 
TSCA Section 5 requires EPA to publish a list of new chemical submissions it has received, including premanufacture notices (PMN), significant new use notices (SNUN), microbial commercial activity notices (MCAN), test market exemption (TME) applications, notices of commencement of manufacture or import (NOC), and test information submitted under Section 5. According to EPA, in 2022 it made available in ChemView more than 25,000 new chemical notice records received under TSCA Section 5, including notices received between 2014 and 2019 that had not been published previously. In 2019, EPA began publishing non-CBI notices on an ongoing basis, and “new records are now generally published within five days of receipt.” EPA states that it will also continue to identify and make public older, previously unpublished new chemicals notices.
 
Notices of Substantial Risk
 
TSCA Section 8(e) requires chemical companies to inform EPA of information that reasonably supports the conclusion that a chemical may present a substantial risk of injury to health or the environment. EPA uses these notices to inform new and existing chemical risk assessment activities. According to EPA, in 2022 it has published 3,900 notices of substantial risk records received under TSCA Section 8(e) in ChemView, including more than 3,300 non-CBI notices submitted between January 1, 2019, and December 20, 2021, that were not previously published due to resource limitations. EPA states that over the next several months, it will publish all non-CBI versions of Section 8(e) notices received from December 20, 2021, to the present. Going forward, “EPA will strive to publish 8(e) notices deemed complete within a week of receiving them from companies.” Additionally, EPA will work to identify and publish Section 8(e) notices received before 2019 as resources allow.
 
Health and Safety Data Reporting
 
Regulations promulgated under TSCA Section 8(d) require chemical companies to submit lists and copies of health and safety studies relating to the health and/or environmental effects of specified chemical substances and mixtures. According to EPA, in 2022 it published more than 1,700 health and safety study records received since September 2021 under TSCA Section 8(d) in ChemView. EPA notes that many of these records were in response to EPA’s 2021 Section 8(d) rulemaking, Health and Safety Data Reporting; Addition of 20 High-Priority Substances and 30 Organohalogen Flame Retardants. EPA states that it expects to publish additional Section 8(d) records “in the future.”

On October 13, 2022, Earthjustice, on behalf of a coalition of environmental organizations and community advocates, petitioned the U.S. Environmental Protection Agency (EPA) to revoke the approval of approximately 600 per- and polyfluoroalkyl substances (PFAS) that were granted through low volume exemptions (LVE) or low release and low exposure exemptions (LoREX) to the premanufacture notice (PMN) requirements of the Toxic Substances Control Act (TSCA). In its October 13, 2022, press release, Earthjustice states that these exemptions “allow EPA to approve chemicals through lax safety reviews only if it ‘will not present an unreasonable risk’ to humans or the environment.” According to Earthjustice, PFAS do not meet that standard, and EPA must revoke previously granted LVEs and LoREXs for PFAS. The petition follows an April 27, 2021, petition filed by Earthjustice on behalf of many of the same petitioners, and it incorporates the 2021 petition by reference.
 
The petition requests the following actions:

• For all outstanding LVEs and LoREXs granted for PFAS, EPA must make a preliminary determination that these LVEs and LoREXs do not meet the terms of TSCA Section 5(h)(4) or 40 C.F.R. Section 723.50(d);
• For all outstanding LVEs and LoREXs granted for PFAS, EPA must notify their manufacturers that it believes their substance does not meet the requirements for a PMN exemption and then proceed to make a final determination based on the current science that no PFAS meets the TSCA Section 5(h)(4) standard for a PMN exemption, taking into account potentially exposed or susceptible subpopulations, in accordance with the protocols set forth in 40 C.F.R. Section 723.50(h);
• In the alternative, EPA must individually re-assess all PFAS for which there is an outstanding LVE and/or LoREX to determine whether the substance meets the standard set forth in 40 C.F.R. Section 723.50(d) and in TSCA Section 5(h)(4); and
• Petitioners incorporate by reference all of the requests set forth in the 2021 petition and reiterate the same requests here:
• EPA must initiate a rulemaking to prohibit: (a) future use of the byproducts exemption for new PFAS; and (b) continued manufacture of any PFAS byproduct under the auspices of the byproducts exemption unless and until such PFAS has undergone a full PMN review and been approved by EPA, with a two-year window for manufacturers to receive such approval; and
• EPA should immediately stop permitting the use of the LVE, LoREX, and polymer exemption for any new PFAS.

The U.S. Environmental Protection Agency’s (EPA) New Chemicals Program will host a webinar on October 18, 2022, on EPA’s process for assessing the potential risks of new chemicals under Section 5 of the Toxic Substances Control Act (TSCA) and the types of data EPA considers in this assessment. The 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.
 
As reported in our June 27, 2022, memorandum, in June 2022, EPA announced a broad outreach effort to describe to stakeholders how EPA 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 will be the second in a series of webinars intended to increase the efficiency and transparency of EPA’s new chemical determinations. As reported in our July 28, 2022, memorandum, 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.

The U.S. Environmental Protection Agency (EPA) has posted a Compliance Advisory entitled “Applicability of the Toxic Substances Control Act to Chemicals made from Petroleum and Renewable Sources Used as Fuels and Fuel Additives and Distillates.”  The Compliance Advisory states that EPA is reaffirming that chemical substances used as fuels, fuel additives, and distillates made from either petroleum or renewable sources are subject to the Toxic Substances Control Act (TSCA).  Anyone who plans to manufacture (including import) a chemical made from petroleum or renewable sources must comply with the statutory and regulatory new chemical requirements under TSCA Section 5.  According to the Compliance Advisory, EPA has received stakeholder inquiries “as to whether fuel and fuel additives made from renewable sources (such as renewable naphtha) are subject to the TSCA new chemicals requirements under section 5.”  EPA states that it is issuing the Compliance Advisory “to affirm that fuel and fuel additives either made from petroleum or renewable sources are subject to TSCA and have been subject to its requirements since 1976.”
 
According to the Compliance Advisory, there are about 142 “naphthas” and 178 “distillates” (that compositionally can qualify as naphthas) currently on the TSCA Inventory, and they are considered Unknown, Variable composition, Complex, or Biological (UVCB) substances.  Any substance that is not on the TSCA Inventory is a new chemical under TSCA Section 5(a)(1)(A).  Prior to manufacture (including import) of a new chemical for commercial use, a premanufacture notice (PMN) must be filed with EPA under TSCA Section 5.  The Compliance Advisory includes several questions and answers (Q&A), including:
 
Can you manufacture or import a chemical substance made from a renewable source if it is not listed on the TSCA Inventory?
 
No.  Anyone who intends to manufacture (including import) a new chemical substance that is subject to TSCA for a non-exempt commercial purpose is required to submit a PMN at least 90 days prior to the manufacture of the chemical.  Manufacturers (importers) are in violation of TSCA if they fail to comply or are late in complying with TSCA notice requirements.  If you are required to submit a PMN, failure to do so is a violation of TSCA Section 15 and you may be subject to penalties.  PMN submissions must include all available data, pursuant to 40 CFR 720.45 and 720.50.  TSCA requires EPA to review the notice and make a determination; and, if appropriate, regulate the proposed activity.
 
EPA’s “compliance advisory” is disappointing.  It signals this EPA is disinclined to promote renewable petroleum cuts and essentially (and emphatically) reaffirms what we believe to be EPA’s inflexible and unimaginative stance on “source” being determinative in petroleum cut UVCBs.  This position, as we have noted in a variety of regulatory contexts, is a substantial disincentive to commercializing renewable petroleum cuts.  EPA’s view is especially problematic when a refinery might wish to use a combination of petroleum and renewable feedstocks to make a single naphtha (or other distillate) cut.
 
For example, to avail itself of the equivalence determination, a company would have to submit a PMN for the renewable equivalent of a petroleum cut, sign the almost certain resultant consent order (EPA will undoubtedly identify aquatic toxicity concerns and may also identify health concerns), commence manufacture, file a Notice of Commencement of Manufacture or Import (NOC), and then request an equivalency determination.  If EPA denies the equivalency determination, any downstream processor or user will have to either segregate the renewable products from the petroleum products so that the downstream entity can maintain records of compliance with the consent order or treat both the renewable and petroleum products as being subject to the order.  Neither option is commercially feasible or sustainable.
 
This sequence of events illustrates why commercial entities are disinclined to avail themselves of renewable sources in the distillate space.  EPA’s “compliance advisory” is an unexpected and, to many, unwanted parting gift from the Trump Administration.  The Biden Administration may wish to revisit the wisdom and prudence of this inflexible, antiquated, and inequitable view.

As reported in our May 29, 2020, blog item, on May 28, 2020, the U.S. Environmental Protection Agency (EPA) Office of Inspector General (OIG) issued a report entitled EPA Toxic Substances Control Act Consent Orders Need Better Coordination.  OIG conducted the evaluation to determine what actions EPA took to verify compliance with the requirements of a 2009 Toxic Substances Control Act (TSCA) Premanufacture Notice Consent Order.  OIG’s recommendations included that EPA implement a process for the Office of Enforcement and Compliance Assurance (OECA) to review and approve the terms and conditions of TSCA Section 5(e) Consent Orders that it is responsible for verifying during compliance monitoring and enforcement activities.  On August 5, 2020, OIG announced that EPA has provided an update to its response to the OIG report.  EPA states that the Office of Civil Enforcement/Waste and Chemical Enforcement Division (OECA/WCED) and the Office of Pollution Prevention and Toxics/Chemical Control Division (OCSPP/CCD) have developed a TSCA Section 5(e) Order Boilerplate that “clarifies and strengthens the provisions of the Order for New Chemical Substances.”  According to EPA, in 2020, OCSPP/CCD and OECA/WCED established and implemented a Standard Operating Procedure (SOP) to ensure that WCED, the office responsible for compliance monitoring and enforcement activities, reviews and approves the terms and conditions of TSCA Section 5(e) Orders developed by CCD.  EPA notes that the establishment of the SOP is intended to meet OIG’s recommendation.  EPA states that the Review and Approval Protocol “provides sufficient assurance that compliance and enforcement requirements in TSCA 5(e) orders will be reviewed and approved by OCSPP and OECA.”  OIG commented on EPA’s updated response, stating that it now considers this recommendation complete.

On June 3, 2020, the U.S. Environmental Protection Agency (EPA) submitted to the Office of Management and Budget (OMB) a final significant new use rule (SNUR) on long-chain perfluoroalkyl carboxylate (LCPFAC) and perfluoroalkyl sulfonate (PFAS) chemical substances.  On March 3, 2020, EPA published a proposed supplemental SNUR for LCPFAC chemical substances that would make inapplicable the exemption for persons who import a subset of LCPFAC chemical substances as part of surface coatings on articles.  85 Fed. Reg. 12479.  Under the proposed supplemental SNUR, issued under Section 5(a)(2) of the Toxic Substances Control Act (TSCA), this subset of LCPFAC chemical substances also includes the salts and precursors of these perfluorinated carboxylates.  The supplemental proposal would require importers to notify EPA at least 90 days before commencing the import of these chemical substances in certain articles for the significant new use described in the proposed SNUR.  The required significant new use notification would initiate EPA’s evaluation of the conditions of use associated with the intended significant new use.  Manufacturing (including import) or processing for the significant new use would be prohibited from commencing until EPA has conducted a review of the notice, made an appropriate determination on the notice, and taken such actions as are required in association with that determination.  As noted in our February 28, 2020, memorandum, “Proposed Supplemental SNUR Would Remove Exemption for LCPFAC Chemical Substances Used as Surface Coatings on Articles,” one of the goals of the proposed supplemental SNUR is to establish the ground rules for EPA’s consideration of the article exemption in future SNUR actions.  The final SNUR that is under OMB review is not publicly available, so it remains to be seen whether EPA has successfully established policies and procedures that both align with statutory requirements and also are workable, effective, predictable, transparent, and justified scientifically.
