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.”

The U.S. Environmental Protection Agency (EPA) announced on April 8, 2021, that it is releasing an updated toxicity assessment for perfluorobutane sulfonic acid (PFBS), which is a member of the group of per- and polyfluoroalkyl substances (PFAS).  EPA states that this PFBS assessment is part of its commitment to restore scientific integrity to all of the Agency’s actions and increase the amount of research and information available to the public on PFAS.  According to EPA’s announcement, “EPA, federal agencies, states, tribes, and local communities can use the PFBS toxicity assessment, along with specific exposure and other relevant information, to determine if and when it is necessary to take action to address potential health risks associated with human exposures to PFBS under appropriate regulations and statutes.”  EPA notes that the updated assessment “has gone through all appropriate reviews, includes input EPA received from external peer review, upholds the tenants of scientific integrity, was authored by expert career scientists in EPA’s Office of Research and Development, and has not been compromised by political staff -- these were all issues with a version of the assessment that was posted during the previous administration.  The release of today’s PFBS assessment upholds the integrity of EPA’s science, which EPA, states, tribes, and more rely on to make decisions that protect the health of their communities.”
 
According to EPA’s fact sheet on the toxicity assessment, PFBS is a replacement chemical for perfluorooctanesulfonic acid (PFOS), a PFAS that was voluntarily phased out by the primary U.S. manufacturer by 2002.  PFBS has been identified in the environment and consumer products, including surface water, wastewater, drinking water, dust, carpeting and carpet cleaners, and floor wax.  The fact sheet states that the PFBS toxicity assessment is comparable to assessments developed under EPA’s Integrated Risk Information System (IRIS) and Provisional Peer-Reviewed Toxicity Value (PPRTV) Programs in that it provides hazard identification, dose-response information, and toxicity values.  EPA will continue to work with state, tribal, and local partners to provide technical assistance as they consider the final PFBS toxicity values in relevant exposure scenarios.  The fact sheet notes that at this time, EPA does not plan to issue a regulation for PFBS.

On March 1, 2021, the U.S. Government Accountability Office (GAO) publicly released a report entitled Man-Made Chemicals and Potential Health Risks:  EPA Has Completed Some Regulatory-Related Actions for PFAS.  GAO was asked to examine the status of regulatory-related actions in EPA’s 2019 Per- and Polyfluoroalkyl Substances (PFAS) Action Plan.  GAO found that EPA completed three of six selected regulatory-related actions for addressing PFAS outlined in the PFAS Action Plan.  For two of the three completed actions, the steps EPA took were also in response to the National Defense Authorization Act for fiscal year 2020 (FY20 NDAA):

  • After proposing a supplemental significant new use rule (SNUR) in February 2020, EPA met a June 2020 deadline set in the FY20 NDAA when the EPA Administrator signed the final rule.  Among other things, under the final rule, articles containing certain PFAS as a surface coating, and carpet containing certain PFAS, can no longer be imported into the United States without EPA review; and
     
  • EPA incorporated 172 PFAS into the Toxics Release Inventory in June 2020.  The FY20 NDAA directed EPA to take this action, extending EPA’s original planned action to explore data for listing PFAS chemicals to the inventory.

Finally, in March 2020, EPA completed a third regulatory-related action, not required under the FY20 NDAA, when it proposed a preliminary drinking water regulatory determination for two PFAS, “an initial step toward regulating these chemicals in drinking water.”
According to GAO, three of the six selected regulatory-related actions are ongoing, and EPA’s progress on these actions varies:

  • As of August 2020, EPA was developing a proposed rulemaking for a nationwide drinking water monitoring rule that includes PFAS, which EPA officials stated that EPA intends to issue in final by December 2021;
     
  • EPA is currently examining available information about PFAS discharges to surface water to identify industrial sources that may warrant further study for potential regulation through EPA’s National Effluent Limitations Guidelines.  EPA expects to publish a final Effluent Guidelines Program Plan 14 in early 2021 that will include an update on the current status of EPA’s multi-industry study; and
     
  • EPA plans to continue the regulatory process for designating two PFAS as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), which would allow EPA to require responsible parties to conduct or pay for cleanup.  On January 14, 2021, EPA issued an advance notice of proposed rulemaking for the hazardous substances designation to obtain public comment and data to inform EPA’s ongoing evaluation of the two PFAS.

On February 4, 2021, the ad hoc committee appointed by the National Academies of Sciences, Engineering, and Medicine (the National Academies) to consider current evidence regarding human health effects of the most widely studied per- and polyfluoroalkyl substances (PFAS) will hold its first meeting.  The National Academies will provide the Centers for Disease Control and Prevention (CDC), the Agency for Toxic Substances and Disease Registry (ATSDR), and the National Institutes of Environmental Health Sciences (NIEHS) “an objective and authoritative review of current evidence regarding human health effects of those PFAS being monitored in the CDC’s National Report on Human Exposure to Environmental Chemicals.”  The National Academies will also provide recommendations regarding potential changes to CDC and ATSDR PFAS clinical guidance, including:

  • Options and considerations to guide decision-making for PFAS testing in a patient’s blood or urine;
  • PFAS concentrations that could inform clinical care of exposed patients; and
  • Appropriate patient follow-up and care specific to PFAS-associated health endpoints for those patients known or suspected to be exposed to PFAS.

The committee will host multiple town hall events in the spring and summer 2021 to hear from PFAS-impacted communities.  The National Academies intends to release the final report in 2022.

On January 22, 2021, the U.S. Environmental Protection Agency (EPA) published the reasons for its denial of a petition requesting it to require health and environmental effects testing on 54 per- and polyfluoroalkyl substances (PFAS).  86 Fed. Reg. 6602.  The petition sought issuance of a rule or order under TSCA Section 4 compelling The Chemours Company (Chemours) to fund and carry out this testing under the direction of a panel of independent scientists.  EPA states that it finds the petitioners have not provided the facts necessary for it to determine for each of the 54 PFAS that “existing information and experience are insufficient and testing of such substance or mixture with respect to such effects is necessary to develop such information.”  After “careful consideration,” EPA denied the TSCA petition for the following reasons:

  • Insufficient Information and Experience:  According to EPA, the petition does not set forth the facts necessary to demonstrate that there is “insufficient information and experience” for each of the 54 PFAS.  The petitioners state, in part, “[f]or the 54 PFAS, the sufficiency of available information should be determined by comparing available data with the known adverse effects of other PFAS.  The goal should be to conduct a scientifically sound assessment of each of the 54 chemicals for the critical toxic endpoints that have been identified in studies on [perfluorooctane sulfonate (PFOS)], [perfluorooctanoic acid (PFOA)] and other well-characterized studies.”  EPA states that the petitioners do not provide evidence that they conducted an assessment to support a finding of insufficient information and experience, however;
     
  • Testing of Such Substance or Mixture with Respect to Such Effects Is Necessary to Develop Such Information:  According to EPA, the petitioners do not demonstrate “testing of such substance or mixture with respect to such effects is necessary to develop such information.”  EPA finds that the petitioners failed to address ongoing testing and data collections for some of the 54 PFAS, thereby failing to set forth facts that are necessary to establish there is a need for the testing sought in the petition.  According to EPA, this research may provide information that overlaps with testing the petitioners requested, which would render the information unnecessary under TSCA Section 4(a)(1)(A)(i)(III);
     
  • Class-Based Approach to Testing:  TSCA Section 4(h)(1)(B)(ii) “encourage[s]” EPA to consider “the grouping of 2 or more chemical substances into scientifically appropriate categories in cases in which testing of a chemical substance would provide scientifically valid and useful information on other chemical substances in the category.”  EPA states that it “is currently investigating ways to group similar PFAS by likeness into subcategories for purposes of research, data collection, hazard determinations, and other activities.”  EPA notes that it collaborated with the National Toxicology Program (NTP) “to construct a PFAS screening library subset composed of 75 PFAS on a structural category basis and considerations such as structural diversity within a category, data availability, and read-across category-level weight (e.g., value of substance for anchoring read-across trends within a category, serving as an analog); four of the 54 PFAS the petitioners identify are included in this subset.”  While the petitioners mention this effort, they “incorrectly state that just two of the 54 PFAS the petitioners cover are included in the EPA testing.”
     
  • Practicability of National Academy of Sciences Oversight:  The petitioners also request that the National Academy of Sciences (NAS) oversee all aspects of the proposed testing program.  EPA states that it “finds such an oversight arrangement is not within the scope of what a TSCA section 21 petitioner can request when seeking the initiation of a rule or the issuance of an order under TSCA section 4.”  Furthermore, according to EPA, projects and studies must meet certain conditions for the NAS to accept private funding.  EPA concludes that it is not in a position to require NAS to oversee the testing requested by the petitioners, and the petitioners provide no administrative or organizational procedures for implementation.
     
  • Selection of PFAS for Health and Environmental Effects Testing:  The petitioners divide the 54 PFAS at issue into Tier 1 substances “for which there is known human exposure based on detection in blood, food or drinking water,” and Tier 2 substances “for which human exposure is probable based on detection in environmental media.”  According to EPA, the petitioners do not set forth facts showing that for all 40 PFAS it ranks as Tier 2 substances “human exposure is probable based on detection in environmental media” or that “a strong inference of exposure can be drawn from their presence in surface water, stormwater, wastewater, sediment, groundwater, soil, private wells, and/or air emissions,” however.
     
  • Scientific Standards:  EPA states that it “finds the petitioners have not evaluated the quality of the data they have provided or indicated how they conducted their searches, evaluated the quality of the sources, or indicated what gaps were located and then explained why the specific tests requested, as compared to others, would provide the data being sought.”  According to EPA, such an evaluation is necessary for EPA to conduct the considerations under TSCA Section 26(h).
     
  • Vertebrate Testing:  TSCA Section 4(h) requires that EPA reduce and replace the use of vertebrate animals in the testing of chemical substances under TSCA Section 4.  EPA states that it must consider “as appropriate and to the extent practicable and scientifically justified, reasonably available existing information, including (i) Toxicity information; (ii) Computational toxicology and bioinformatics; and (iii) High-throughput screening methods and the prediction models of those methods.”

More information on the TSCA Section 21 petition is available in our October 29, 2020, memorandum, “TSCA Section 21 Petition Seeks Section 4 Test Rule for 54 PFAS.”

On December 22, 2020, the U.S. Environmental Protection Agency (EPA) announced the availability of new interim guidance on destroying and disposing of certain perfluoroalkyl and polyfluoroalkyl substances (PFAS) and PFAS-containing materials for public comment.  85 Fed. Reg. 83554.  The interim guidance outlines the current state of the science on techniques and treatments that may be used to destroy or dispose of PFAS and PFAS-containing materials from non-consumer products, including aqueous film-forming foam for firefighting.  According to EPA’s December 18, 2020, press release, the interim guidance assembles and consolidates information in a single document that generally describes thermal treatment, landfill, and underground injection technologies that may be effective in the destruction or disposal of PFAS and PFAS-containing materials.  To help ensure informed decision-making, the technology-specific information describes uncertainties and how those uncertainties should be weighed given situation-specific factors, such as the waste’s physical phase (liquid, solid, gas).
 
As required by the National Defense Authorization Act for Fiscal Year 2020 (FY20 NDAA), the interim guidance addresses PFAS and PFAS-containing materials including:

  • Aqueous film-forming foam (for firefighting);
  • Soil and biosolids;
  • Textiles, other than consumer goods, treated with PFAS;
  • Spent filters, membranes, resins, granular carbon, and other waste from water treatment;
  • Landfill leachate containing PFAS; and
  • Solid, liquid, or gas waste streams containing PFAS from facilities manufacturing or using PFAS.

EPA notes that the interim guidance is not intended to address destruction and disposal of PFAS-containing consumer products, such as non-stick cookware and water-resistant clothing.  EPA is also providing guidance on testing and monitoring air, effluent, and soil for releases near potential destruction or disposal sites.  The interim guidance captures the significant information gaps associated with PFAS testing and monitoring and identifies specific research needs to address the FY20 NDAA requirements.  Comments are due February 22, 2021.

On June 30, 2020, the Trump Administration released the Spring 2020 Unified Agenda of Regulatory and Deregulatory Actions for the U.S. Environmental Protection Agency (EPA.)  According to the Unified Agenda, the Office of Chemical Safety and Pollution Prevention (OCSPP) is working on several rulemakings under the Toxic Substances Control Act (TSCA).  Rulemakings at the proposed stage are listed below:

  • Review of Dust-Lead Post-Abatement Clearance Levels.  On June 24, 2020, EPA published a proposed rule that would lower the amount of lead that can remain in dust on floors and windowsills after lead removal activities (dust-lead clearance levels (DLCL)) from 40 micrograms (µg) of lead in dust per square foot (ft2) to 10 µg/ft2 for floor dust and from 250 µg/ft2 to 100 µg/ft2 for window sill dust.  85 Fed. Reg. 37810.  Comments on the proposed rule are due August 24, 2020.  EPA intends to publish a final rule in September 2020.
     
  • Reporting and Recordkeeping for Certain Chemicals under TSCA Section 8(a).  EPA is developing a rulemaking under TSCA Section 8(a) to add certain chemicals that are on the TSCA Work Plan to the Chemical-Specific Reporting and Recordkeeping rules in 40 C.F.R. Part 704, Subpart B.  EPA is developing this rule to obtain information about potential hazards and exposure pathways related to certain chemicals on the TSCA Work Plan, particularly occupational, environmental, and consumer exposure information.  EPA states that this information is needed to inform prioritization and risk evaluation of the chemical substances, as mandated under TSCA Section 6.  EPA intends to issue a notice of proposed rulemaking (NPRM) in November 2020 and a final rule in June 2021.
     
  • Revisions to the Fees Rule under TSCA.  EPA is reviewing its 2018 final rule that established the requirements and procedures for setting and collecting fees from chemical manufacturers (including importers) and, in some cases, processors, submitters of new chemical substances, and others.  TSCA Section 26(b)(4)(F) requires EPA to review and adjust the fees every three years and to consult with parties potentially subject to fees when the fees are reviewed and updated to reflect changes in program costs.  EPA states that in addition to possible revisions resulting from this review, consistent with its announcement in March 2020, it will also consider proposing exemptions to the current rule’s self-identification requirements associated with EPA-initiated risk evaluations for manufacturers that:  (1) import the chemical substance in an article; (2) produce the chemical substance as a byproduct; and (3) produce or import the chemical substance as an impurity.  EPA intends to issue an NPRM in December 2020 and a final rule in October 2021.  More information on EPA’s March 2020 announcement is available in our April 17, 2020, blog item.
     
  • Updates to New Chemicals Procedural Regulations to Reflect the 2016 TSCA Amendments:  EPA states that the 2016 amendments impacted how it reviews and makes determinations on new chemical notices under TSCA Section 5.  EPA acknowledges that as a result of these increased responsibilities, “it has become more challenging for EPA to complete reviews within 90 days.”  This rulemaking seeks to revise the 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.  EPA intends 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 2020 and a final rule in July 2021.

Rulemakings at the final stage include:

  • Significant New Uses of Chemical Substances; Updates to the Hazard Communication Program and Regulatory Framework; Minor Amendments to Reporting Requirements for Premanufacture Notices.  On July 28, 2016, EPA proposed amending components of the Significant New Uses of Chemical Substances regulations at 40 C.F.R. Section 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).  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.  EPA intends to issue a final rule in August 2020.  More information on the proposed rule is available in our July 29, 2016, memorandum, “:  TSCA:  Proposed Revisions to Significant New Use Rules Reflect Current Occupational Safety and Health Standards.”
     
  • Long-Chain Perfluoroalkyl Carboxylate (LCPFAC) and Perfluoroalkyl Sulfonate Chemical Substances (PFAS); Significant New Use Rule (SNUR).  In a January 21, 2015, proposed SNUR for LCPFAC and PFAS chemical substances, EPA proposed to require notification of significant new uses from persons who import a subset of LCPFAC chemical substances as part of any article.  80 Fed. Reg. 2885.  EPA proposed to make the exemption from notification requirements for persons who import the chemical substance as part of an article inapplicable for the import of a subset of LCPFAC chemical substances in all articles.  As reported in our February 28, 2020, memorandum, “Proposed Supplemental SNUR Would Remove Exemption for LCPFAC Chemical Substances Used as Surface Coatings on Articles,” EPA issued a supplemental proposal that would make inapplicable the exemption for persons who import a subset of LCPFAC chemical substances as part of surface coatings on articles.  EPA intended to issue a final rule in June 2020.
     
  • Decabromodiphenyl Ether (DecaBDE); Regulation of Persistent, Bioaccumulative, and Toxic (PBT) Chemicals under TSCA Section 6(h).  TSCA Section 6(h) directs EPA to issue regulations under Section 6(a) for certain PBT chemical substances identified in the 2014 update of the TSCA Work Plan.  EPA states that it is selecting among the available prohibitions and other restrictions in TSCA Section 6(a) to address risks of injury to health or the environment that the Administrator determines are presented by the chemical substances and reduce exposure to the chemical substances to the extent practicable.  Since the statute states that a risk evaluation is not required for these chemical substances under TSCA Section 6(h), EPA developed an exposure and use assessment.  According to the Unified Agenda item, EPA intends to take final action on all of the chemicals that were addressed in the July 29, 2019, proposed rule (i.e., the following PBT chemicals identified in TSCA Section 6(h):  DecaBDE; phenol, isopropylated phosphate  (PIP) (3:1); 2,4,6-tris(tert-butyl)phenol (TTBP); pentachlorothiophenol (PCTP); and hexachlorobutadiene (HCBD).  Although addressed in a single proposed rule, EPA intends to issue separate final rules.  EPA proposed to prohibit the manufacture (including import), processing, and distribution in commerce of DecaBDE, and articles and products to which DecaBDE has been added with several exceptions, and proposed to require affected persons to maintain, for three years from the date the record is generated, ordinary business records that demonstrate compliance with the restrictions, prohibitions, and other requirements.  EPA intends to issue a final rule in December 2020.  More information is available in our June 24, 2019, memorandum, “EPA Publishes Proposed PBT Chemicals Rule under TSCA.”
     
  • PIP (3:1); Regulation of PBT Chemicals under TSCA Section 6(h).  EPA proposed to prohibit the processing and distribution in commerce of PIP (3:1), and products containing the chemical substance with several exceptions; prohibit releases to water from the non-prohibited processing, distribution in commerce, and commercial use activities.  Persons manufacturing, processing, and distributing PIP (3:1), and products containing PIP (3:1), in commerce would be required to notify their customers of these restrictions, and EPA proposed to require affected persons to maintain, for three years from the date the record is generated, ordinary business records that demonstrate compliance with the restrictions, prohibitions, and other requirements.  EPA intends to issue a final rule in December 2020.
     
  • TTBP; Regulation of PBT Chemicals under TSCA Section 6(h.).  EPA proposed to prohibit the distribution in commerce of 2,4,6-TTBP and products containing 2,4,6-TTBP in any container with a volume of less than 55 gallons for any use to prevent the use of 2,4,6-TTBP as a fuel additive or fuel injector cleaner by consumers and small commercial operations (e.g., automotive repair shops, marinas).  The proposed restriction also would prohibit processing and distribution in commerce of 2,4,6-TTBP, and products containing 2,4,6-TTBP, for use as an oil or lubricant additive, regardless of container size.  EPA also proposed to require affected persons to maintain, for three years from the date the record is generated, ordinary business records that demonstrate compliance with the restrictions, prohibitions, and other requirements.  EPA intends to issue a final rule in December 2020.
     
  • PCTP; Regulation of PBT Chemicals under TSCA Section 6(h).  EPA proposed to prohibit the manufacture (including import), processing, and distribution in commerce of PCTP, and products containing PCTP, unless in concentrations at or below one percent by weight; and proposed to require affected persons to maintain, for three years from the date the record is generated, ordinary business records that demonstrate compliance with the restrictions, prohibitions, and other requirements.  EPA intends to issue a final rule in December 2020.
     
  • HCBD; Regulation of PBT Chemicals under TSCA Section 6(h).  For HCBD, EPA proposed no regulatory action.  EPA intends to issue a final rule in December 2020.
