B. What is the Agency’s authority for 
taking this action? 
Section 6(h) of TSCA, 15 U.S.C. 
2605(h), directs EPA to take expedited action on certain persistent, bioaccumulative, and toxic (PBT) chemical substances. For chemical substances that meet the statutory criteria, EPA is directed to issue final rules that address the risks of injury to health or the environment that the Administrator determines are present and to reduce exposure to the substance(s) to the extent practicable. In response to this directive, EPA identified PIP (3:1) as meeting the TSCA section 6(h) criteria and issued a final rule for PIP (3:1) on January 6, 2021 (Ref. 1). 
With the obligation to promulgate 
these rules, the Agency also has the authority to amend them if circumstances change, including in relation to the receipt of new information and in relation to compliance deadlines established under TSCA section 6(d). It is well settled that EPA has inherent authority to reconsider, revise, or repeal past decisions to the extent permitted by law so long as the Agency provides a reasoned explanation. See FCC v. Fox 
Television Stations, Inc., 556 U.S. 502, 515 (2009). Here, as explained further in Unit I.D., based on information submitted by regulated entities, the Agency proposes that revised compliance dates are necessary to address comments that the original compliance dates were not practicable and did not provide adequate transition time because they would have caused extensive harm to the economy and 
public due to unavailability of critical goods and equipment. 
C. What action is the Agency taking? 
The January 2021 final rule for PIP 
(3:1) prohibits the processing and 
distribution of PIP (3:1), PIP (3:1)- containing products, and PIP (3:1)- containing articles, with specified exclusions; prohibits or restricts the release of PIP (3:1) to water during manufacturing, processing, distribution, and commercial use; and requires persons manufacturing, processing, and distributing in commerce PIP (3:1) and products containing PIP (3:1) to notify their customers of these prohibitions and restrictions and to keep records. Several different compliance dates were established, the first of which was 60 days after publication, or March 8, 2021, after which processing and distribution of PIP (3:1), PIP (3:1)-containing products, and PIP (3:1)-containing articles were prohibited unless an alternative compliance date or exclusion was otherwise provided. A recently issued final rule extended the compliance date applicable to the processing and distribution in commerce of certain PIP (3:1)- containing articles, and the PIP (3:1) used to make those articles, from March 8, 2021 to March 8, 2022, along with the associated recordkeeping requirements (Ref. 2). 
EPA is proposing to amend the 
regulations at 40 CFR 751.407(a)(2) to further extend the phased-in prohibition, established in the September 2021 final rule, for the processing and distributing in commerce of PIP (3:1) for use in certain articles, and for the processing and distributing in commerce of certain PIP (3:1)-containing articles, from March 8, 2022 to October 31, 2024. This proposal would also extend the compliance date 
for the recordkeeping requirements for manufacturers, processors, and distributors of PIP (3:1)-containing articles from March 8, 2022, to October 31, 2024. EPA is seeking public comment on the compliance deadline. Articles covered by the phased-in prohibition include any article not otherwise covered by an alternative compliance deadline or exclusion described in 40 CFR 751.407(a)(2)(ii) or (b). 
EPA is also announcing its intention 
to commence a new rulemaking effort on PIP (3:1) and the other four chemicals that have been regulated under TSCA section 6(h), which are 2,4,6-tris(tert-butyl)phenol (2,4,6-TTBP), decabromodiphenyl ether (decaBDE), pentachlorothiophenol (PCTP), and hexachlorobutadiene (HCBD) (Refs. 3, 4, 
5, and 6). EPA is anticipating issuing a proposal to this end in 2023. EPA is reviewing the provisions of all five of the final rules issued under TSCA section 6(h), evaluating the other applicable provisions of amended TSCA, and determining how the Executive Orders and other Administration priorities (Refs. 7, 8, 9, 10, and 11) could be addressed, along with the additional information that has been provided by stakeholders in response to the March 2021 notification and request for comments. More information on this rulemaking can be found in Unit III.C. 
D. Why is the Agency taking this action? 
EPA is issuing this proposal to further 
address the hardships inadvertently 
created by the January 2021 final rule on PIP (3:1) (Ref. 1) due to uses and supply chain challenges that were not communicated to EPA until after the rule was published. Shortly after the final rule was published in January 2021, many stakeholders, including, for example, the electronics and electrical manufacturing sector and their customers, raised significant concerns about their ability to meet the March 8, 2021, compliance date for PIP (3:1)- containing articles (Ref. 12). These stakeholders requested an extension of the compliance dates in order to clear the existing articles through the supply chain, find and certify an alternative chemical, and produce or import new articles that do not contain PIP (3:1). In the Federal Register of March 16, 2021 
(Ref. 13), EPA requested additional comment on this specific issue, as well as on other aspects of all the TSCA section 6(h) final rules in general (Refs. 1, 3, 4, 5, and 6). According to the comments received in response to the March 2021 notification and request for comments, a wide range of key consumer and commercial goods are affected by the prohibitions in the PIP (3:1) final rule such as cellular telephones, laptop computers, and other electronic devices and industrial and commercial equipment used in various sectors including transportation, life sciences, and semiconductor production (Ref 14). This proposal follows a final rule that published in the Federal Register of September 17, 2021, that 
extended the compliance date applicable to the processing and distribution in commerce of certain PIP (3:1)-containing articles, and the PIP 
(3:1) used to make those articles, until March 8, 2022, along with the associated recordkeeping requirements for manufacturers, processors, and distributors of PIP (3:1)-containing 
VerDate Sep<11>2014 16:49 Oct 27, 2021 Jkt 256001 PO 00000 Frm 00034 Fmt 4702 Sfmt 4702 E:\FR\FM\28OCP1.SGM 28OCP1jspears on DSK121TN23PROD with PROPOSALS159686 Federal Register / Vol. 86, No. 206 / Thursday, October 28, 2021 / Proposed Rules 
articles (Ref. 2). That final rule provided 
a necessary short-term extension to avoid immediate and significant disruption in the supply chains for important articles, to provide the public with regulatory certainty in the near term, and to allow EPA additional time to further evaluate the need to again extend the compliance deadlines for PIP (3:1). EPA responded to the comments received on the March 2021 notification that were relevant to the compliance deadline extension and related issues as part of the recent final rule (Ref. 2). EPA will respond to comments from the March 2021 notification not already addressed in the September 2021 final rule either as part of this rulemaking or as part of the subsequent rulemaking on the five PBTs. EPA is requesting comment on a further extension of the compliance dates beyond March 8, 2022 for the processing and distribution of certain PIP (3:1)-containing articles, and the PIP (3:1) used to make those articles. This proposed extension of the compliance dates until October 31, 2024, is based on the detailed information provided by several industry commenters. 
E. What are the incremental economic 
impacts? 
EPA evaluated the potential 
incremental economic impacts and determined that these changes would reduce the existing burden of this action. The quantified effect of this compliance date extension reflects the difference between the incremental cost and benefits of the final rule as it was originally promulgated and the incremental cost and benefits of this proposed rule with the compliance date in place. This was estimated as the difference between the cost and benefits of the final rule after a compliance extension of March 8, 2022, and the cost and benefits of this proposed rule with an October 31, 2024, compliance date. Quantified costs for substitution and recordkeeping were estimated to be incurred later, assuming they will be incurred when the proposed compliance date extension expires. In summary, extending the compliance date from March 8, 2022 to October 31, 2024 for PIP (3:1)-containing articles would result in an estimated annualized cost savings of $1.8 million (from $24.1 to $22.3 million) at a 3 percent discount rate or $2.4 million (from $23.4 to $21.0 million) at a 7 percent discount rate over a 25-year time horizon. While the 
Agency has no data to quantify this, qualitative costs savings may include providing more time for manufacturers and retailers to sell articles prior to the prohibition deadline rather than being forced to dispose of them, thereby avoiding loss of revenue from those products. In addition to these cost savings, reformulation (which can include research and development, laboratory testing, and re-labeling) will be facilitated once an acceptable substitute is certified given that companies will have more time to gather information regarding the steps involved in the reformulation process. Cost reductions for reformulation are not certain, however, since the time required to identify viable substitutes can be complex and unpredictable. The level of these cost savings is dependent on complexity of achieving needed efficacy, length of time needed for testing and quality control, and the current status of development of alternatives, which may vary greatly by sector and end use product. Lastly, the compliance date extension may provide additional time for information gathering through the supply chain to alleviate the necessity for chemical testing of certain articles. Although the benefits of the final rule were not quantified, the extension would also postpone decreases in potential releases and exposures to PIP (3:1). Due to discounting, in a manner similar to costs, this postponement would lead to lower potential benefits. On balance, this proposed further extension of the compliance dates is appropriate to prevent the disruptive consequences of implementing the prohibition on March 8, 2022 without a further compliance extension. The economic consequences (such as loss of supply) could be severe, given the apparent ubiquity of the chemical in commerce. Thus, EPA is proposing to determine that the cost savings and avoidance of disruption to industry outweigh the delayed realization of benefits that may accrue from reduced exposure.

II. Background A. The January 2021 Final Rule 
A final rule for PIP (3:1) was 
published in the Federal Register on 
January 6, 2021 (Ref. 1). EPA determined in the final rule that PIP (3:1) met the TSCA section 6(h)(1)(A) criteria for expedited action. In addition, EPA determined, in accordance with TSCA section 6(h)(1)(B), that exposure to PIP (3:1) was likely under the conditions of use to the general population, to a potentially exposed or susceptible subpopulation, or the environment. The PIP (3:1) final rule prohibits processing and distribution in commerce of PIP (3:1), and products or articles containing the chemical substance, for all uses, except for the following different compliance dates or exclusions: 
•Use in photographic printing 
articles after January 1, 2022; 
•Use in aviation hydraulic fluid in 
hydraulic systems and use in specialty hydraulic fluids for military applications; 
•Use in lubricants and greases; 
•Use in new and replacement parts 
for the aerospace and automotive industries; 
•Use as an intermediate in the 
manufacture of cyanoacrylate glue; 
•Use in specialized engine air filters 
for locomotive and marine applications; 
•Use in sealants and adhesives after 
January 6, 2025; and 
•Recycling of plastic that contained 
PIP (3:1) before the plastic was recycled, and the articles and products made from such recycled plastic, provided no new PIP (3:1) is added during the recycling or production process. 
In addition, the final rule requires 
manufacturers, processors, and distributors of PIP (3:1) and products containing PIP (3:1) to notify their customers of these restrictions. Finally, the rule prohibits releases to water from the remaining manufacturing, processing, and distribution in commerce activities, and requires commercial users of PIP (3:1) and PIP (3:1)-containing products to follow existing regulations and best practices to prevent releases to water during use. 
Also defined at 40 CFR 751.403 for 
the purposes of 40 CFR part 751, subpart E, which includes the PIP (3:1) final rule, are the terms ‘‘article’’ and 
VerDate Sep<11>2014 16:49 Oct 27, 2021 Jkt 256001 PO 00000 Frm 00035 Fmt 4702 Sfmt 4702 E:\FR\FM\28OCP1.SGM 28OCP1jspears on DSK121TN23PROD with PROPOSALS159687 Federal Register / Vol. 86, No. 206 / Thursday, October 28, 2021 / Proposed Rules 
‘‘product’’ (Ref. 3). ‘‘Article’’ is defined 
as a manufactured item: (1) Which is formed to a specific shape or design during manufacture, (2) Which has end use function(s) dependent in whole or in part upon its shape or design during end use, and (3) Which has either no change of chemical composition during its end use or only those changes of composition which have no commercial purpose separate from that of the article, and that result from a chemical reaction that occurs upon end use of other chemical substances, mixtures, or articles; except that fluids and particles are not considered articles regardless of shape or design. For example, laptop computers are articles, as are the internal components such as chips, wiring, and cooling fans. ‘‘Product’’ is defined as the chemical substance, a mixture containing the chemical substance, or any object that contains the chemical substance or mixture containing the chemical substance that is not an article. For example, hydraulic fluids and motor oils are products. 
B. The March 2021 Notification and the 
No Action Assurance 
Shortly after the publication of the 
January 2021 final rule, a wide variety of stakeholders from various sectors, including the electronics and electrical manufacturing community and their customers, started raising concerns about the March 8, 2021, compliance date in that final rule for the prohibition on the processing and distributing in commerce of PIP (3:1) for use in articles and PIP (3:1)-containing articles (Ref. 12). These stakeholders contended that they needed significantly more time to identify whether and where PIP (3:1) might be present in articles in their supply chains, find and certify alternative chemicals, and produce or import new articles that do not contain PIP (3:1). Despite EPA’s extensive outreach, most stakeholders contacting EPA after the rule was finalized did not comment on the proposal or otherwise engage with the agency on the PIP (3:1) rulemaking, and do not appear to have previously surveyed their supply chains to determine if PIP (3:1) was being used. Several indicated that they did not understand that articles can be regulated under TSCA, and that, because PIP (3:1) is not regulated by other authorities, including those of other countries or under international agreements, there was a lack of awareness relative to its presence in the supply chain (Ref. 14). 
Absent engagement and timely or specific input from these stakeholders that could be used as a basis for granting further extensions or exemptions from the proposed prohibition, in the final rule EPA believed that PIP (3:1) was not widely present in articles outside the aerospace and automotive sectors. While some commenters on the 2019 proposed rule indicated that PIP (3:1) may be present in articles, their comments were very general and did not identify specific uses or specific concerns with the March 8, 2021, compliance date. 
Based on the concerns raised by 
stakeholders shortly after publication of the final rule, EPA issued a No Action Assurance (NAA) on March 8, 2021, in an effort to ensure that the supply chains of these important articles were not interrupted while the agency collected the information needed to best inform subsequent regulatory efforts (Ref. 15). The NAA only described how the agency will exercise its enforcement discretion, the NAA did not change the March 8, 2021, compliance date. 
Shortly after the NAA was issued, 
EPA published in the ‘‘Proposed Rules’’ section of the Federal Register of March 16, 2021, a notification and request for comments on the five final PBT rules in general and, more specifically, on the compliance date issues with respect to PIP (3:1)-containing articles that had been raised by stakeholders. The Federal Register document described in particular the issues raised by industry stakeholders regarding the March 8, 2021, compliance date, including the types of articles affected, such as those used in a wide variety of electronics, ranging from cellular telephones, to robotics used to manufacture semiconductors, to equipment used to move COVID–19 vaccines and keep them at the appropriate temperature. The document further outlined the complexity of international supply chains described by industry stakeholders and how, according to those stakeholders, that complexity creates challenges for identifying and finding alternatives to PIP (3:1) in complex supply chains. In the document, EPA asked commenters to specifically describe the following regarding PIP (3:1)-containing articles: 
•The articles that would need an 
alternative compliance date; 
•The basis for such an alternative 
compliance date, taking into consideration the reasons supporting alternative compliance dates in the final rule already issued, such as the January 1, 2022, date for photographic printing articles and the January 6, 2025, date for adhesives and sealants, with supporting documentation; and 
•The additional time needed for 
specific articles to clear channels of trade. EPA received a total of 122 comments 
in response to the March 2021 
notification and request for comments; 78 of these were from industry stakeholders, most of whom were concerned about compliance for PIP (3:1)-containing articles (Ref 14). Stakeholders concerned about PIP (3:1)- containing articles reiterated that they needed much more time, up to 15 years (Ref. 16), in order to identify where PIP (3:1) might be present in their supply chains, find and certify alternatives, and produce or import new articles that do not contain PIP (3:1). More information on the comments received can be found in the September 2021 final rule (Ref. 2), which is further discussed in Unit. II.C. 
C. The September 2021 Final Rule 
Based on the comments received in 
response to the March 2021 notification 
and request for comments, EPA issued a final rule extending the compliance dates applicable to the processing and distribution in commerce of certain PIP (3:1)-containing articles, and the PIP (3:1) used to make those articles, until March 8, 2022, along with the associated recordkeeping requirements for manufacturers, processors, and distributors of PIP (3:1)-containing articles. While most commenters on the March 2021 notification and request for comments requested a longer compliance date extension, EPA 
determined that a short-term extension was necessary to ensure that the supply chains for these important articles continue uninterrupted in the near term while allowing EPA to conduct notice and comment rulemaking to provide an opportunity for comments in response to this proposal on a longer-term compliance date extension generally. 
D. Comments Received in Response to 
the March 2021 Notification 
This Unit describes the comments 
received specifically on the issue of compliance dates for the prohibition on the processing and distribution in commerce of PIP (3:1)-containing articles, and the PIP (3:1) used to make those articles, as well as on the associated recordkeeping requirements. Comments received on other aspects of the January 2021 PIP (3:1) final rule, as well as on the final rules for the other four PBT chemicals, are outside of the scope of this rulemaking and will be addressed in a future rulemaking effort as described in Unit III.C. 
1. Comments on articles that contain, 
or potentially contain, PIP (3:1). During the public comment period for the March 2021 notification and request for comments, industry commenters identified a wide range of articles that 
VerDate Sep<11>2014 16:49 Oct 27, 2021 Jkt 256001 PO 00000 Frm 00036 Fmt 4702 Sfmt 4702 E:\FR\FM\28OCP1.SGM 28OCP1jspears on DSK121TN23PROD with PROPOSALS159688 Federal Register / Vol. 86, No. 206 / Thursday, October 28, 2021 / Proposed Rules 
may contain PIP (3:1). PIP (3:1) is 
generally used as a flame retardant and plasticizer in plastic articles. Articles which have been identified or are being investigated for the presence of PIP (3:1) include polyvinyl chloride (PVC) tubes, harnesses, cables, covers, sleeves, and casings, which include AC power cords and USB cables for consumer and commercial articles such as laptops, televisions, and gaming consoles. According to the electrical manufacturing industry, a representative sample of articles made possible by the qualities unique to PIP (3:1) include medical devices, capacitors, inverters, generators, transformers, semiconductor wafers, computers, and electrical appliances (Ref. 17). Manufacturers of construction, agriculture, forestry, mining, and utility equipment have identified PIP (3:1) in fire prevention systems, engine emission control systems, electronics, wiring harnesses, hydraulic hoses, switches, fabrics, PVC articles, resin in fiberglass articles, paints, elastomers, foam, resistors, splitters, articles that are alarm components, automatic tire inflation equipment, and wire sleeving (Ref. 18). According to another commenter, in construction, agriculture, forestry, mining, and utility equipment, PIP (3:1) is frequently found in wire harnesses, starters, water pumps, motor gears, pre-wired motors, ground cables, and compressors (Ref. 19). The semiconductor manufacturing industry has identified the use of PIP (3:1) in semiconductor-related manufacturing equipment (as well as microelectromechanical-related, solar- related, and LED-related manufacturing equipment) and semiconductor fabrication facilities’ support equipment and infrastructure, such as laboratory, substrate and device (e.g., die) 
preparation, and assembly and test operations, including advanced packaging (Ref. 16) as well as articles that are internal components of high- tech robotics and manufacturing equipment. Additionally, the chemical has been identified in articles that are components in scanning electron microscopes utilized in research, national laboratories, and academia (Ref. 20). 
EPA generally agrees with these 
commenters that PIP (3:1) is used in a variety of articles, especially in plastic articles that are components of electronics or electrical articles. Further, at the time the January 2021 final rule was issued, EPA did not understand the extent to which PIP (3:1) is used in articles beyond those articles specifically addressed in that final rule, which are photographic printing 
articles, new and replacement parts for aerospace and motor vehicles, specialized locomotive and marine engine air filters, and recycled plastics. EPA notes that this proposed rule would not affect the compliance dates established for these specific articles in the January 2021 final rule. EPA outlined its understanding on the use of PIP (3:1) in articles in responding to public comments on the January 2021 final rule, ‘‘[t]here is little evidence to suggest that PIP (3:1) is present in articles which may be available to consumers, and outside of activities excluded from the prohibition, little evidence to suggest it is necessary or present in commercial and industrial articles as well’’ (Ref. 30). 
2. Comments on the challenges 
associated with determining whether articles contain PIP (3:1). These commenters also described in some detail the challenges associated with determining whether a particular article contains PIP (3:1), especially for complex goods that contain thousands of individual parts. Commenters noted that a manufacturer of a complex good could have upwards of 5,000 suppliers for potentially 100,000 or more component articles across all product lines (Ref. 21). These commenters also noted that manufacturers do not receive a list of every chemical within each part or component article that ultimately goes into a finished electronic article because ingredient lists are highly proprietary and confidential. Rather, companies provide functionality, performance, safety and quality specifications of a part or component article to their supply chain, including specifications regarding chemical restrictions. According to these commenters, suppliers are provided lists of restricted chemicals on at least an annual basis, or more frequently if there is a triggering event, such as a new government restriction. Suppliers are notified of the lead time for the restriction of the chemical and any testing that may be required, which information they communicate to their own suppliers. 
According to these commenters (Ref. 
21), the task of determining whether PIP (3:1) is used in a component article in a finished electronic good is further complicated by the many article manufacturers being unable to identify or confirm the PIP (3:1) content of articles, such as supplied parts, components or commercial and consumer goods, without laboratory testing. Laboratory testing can run up to 
$5,000 per product and take up to one (1) month. As a result, companies must rely on material declarations by 
suppliers as a more practicable and reliable approach to determine the usage of PIP (3:1) within an article. 
Other commenters echo these 
concerns. Comments from the heating, ventilation, air conditioning, and refrigeration (HVACR) industry note that manufacturers are currently parsing through tens of thousands of stock- keeping units (SKUs), each having hundreds of associated component articles and spare parts (Ref. 22). They contend that their suppliers have generally not been forthright about the presence of PIP (3:1) in their component articles and parts, even after receiving notification that the use of PIP (3:1) in component articles must be disclosed. According to these commenters, some suppliers continue to claim that they will not disclose the chemical makeup of component articles as the composition is confidential intellectual property. In response, some of the larger manufacturers have started testing component articles to compensate for this lack of transparency, but testing is time-consuming and costly and most smaller businesses do not have the resources to undertake testing. 
The semiconductor industry and the 
testing and measurement industry noted that their industries differ from the consumer electronics industry and the automotive industry, in that their industries are high-mix, low-volume industries, meaning that manufacturer portfolios are typically comprised of a large number of unique goods with relatively low unit sales (Refs. 16 and 23). Their equipment is primarily built to order and sold directly to professional and industrial customers by the manufacturers (Ref. 23). The semiconductor industry typically places only 600 to 6,000 units of semiconductor manufacturing and related equipment into U.S. commerce each year and it is not uncommon for small groups of model units to be customized to an end user’s particular needs (Ref. 16). According to this commenter, this is in stark contrast to most consumer goods, in which individual similar model units are placed into U.S. commerce in much greater number, and to the automotive and aerospace sectors, in which goods are manufactured in lower quantities but which are quite similar from model unit to model unit (Ref. 16). The semiconductor industry further noted that their sector’s ability to obtain material composition data from across their supply chain is limited due to three factors: (1) The length and 
complexity of the supply chain; (2) the preponderance of suppliers located

outside of the U.S.; and (3) the tens of 
thousands of parts incorporated into each article eventually manufactured or distributed in commerce within the U.S. 
EPA generally recognizes the 
challenges described by these commenters in determining whether and where PIP (3:1) is present in articles in their supply chains and how long it may take to clear those PIP (3:1)- containing articles through the channels of trade. As to comments relating to testing, as most commenters note, there are a number of alternative steps to testing that an importer or a domestic manufacturer can take to ensure that an article does not contain PIP (3:1). The customer can include a specification in their purchase contracts with suppliers that articles be made without PIP (3:1). The customer can also request that their suppliers provide them with a written statement or certification that the purchased or supplied goods are made without PIP (3:1). Of course, testing is always an option, but EPA recognizes that this may be a more expensive option. 
3. Comments on compliance date 
considerations for PIP (3:1)-containing articles. Nearly all of the industry commenters responding to EPA’s March 2021 request for comments stated that they needed several years to phase PIP (3:1) out of their articles (Ref. 14). Many commenters contended that they needed much longer, up to fifteen years (Refs. 16 and 20) assuming that it is even feasible to do so. Only two commenters, representing individual companies, indicated that they would need less than three years (Refs. 24 and 25). Commenters identified a number of steps that would be needed in order to complete a phase-out of PIP (3:1) in articles. These steps include: (1) Identifying whether and where PIP (3:1) is present; (2) identifying and testing substitutes; (3) re-certifying (as needed) the replacement article; and (4) distributing the replacement article throughout the supply chain. Some commenters provided detailed timelines for the steps needed to replace PIP (3:1). 
For example, the consumer 
electronics industry noted that, while companies had begun to survey their suppliers as soon as the final rule was published, because of the large number of parts and suppliers involved for most manufacturers, they anticipated that completing the survey would take between six and twelve months (Ref. 21). They also noted that, because PIP (3:1) is not regulated in other international markets, there is a general lack of awareness regarding the chemical throughout the supply chain and the industry expects the surveys to 
take closer to twelve months than six. 
According to the consumer 
electronics industry commenters, once PIP (3:1) is identified in a particular part by a particular supplier, the supplier must identify and investigate alternatives to PIP (3:1) that can meet regulatory requirements and manufacturer requirements with respect to functionality, performance, safety and quality (Ref. 21). Given that PIP (3:1) is typically used in electronic component articles to meet safety standards related to flammability, a component article that includes a PIP (3:1) alternative will have to be certified to the applicable safety standard (Ref. 21). Common safety standards that apply to consumer electronics, according to the commenters, include Underwriters Laboratory UL94, entitled ‘‘Tests for Flammability of Plastic Material for Part in Devices and Applications,’’ and UL498, entitled ‘‘Attachment Plugs and Receptacles.’’ The timeline for retesting and recertification of replacement component articles is determined by the certification organization, and consumer electronics manufacturers estimate that testing could take anywhere from 3 to 24 months (Ref. 21). 
These commenters detail the next 
steps in replacing a PIP (3:1)-containing component article (Ref. 21). Once the manufacturer of the finished consumer electronics good receives the replacement component article, the manufacturer will conduct its own internal quality assessments. The manufacturer will conduct an initial assessment on whether the component article works, has the correct performance characteristics, and maintains brand integrity. Once these basic parameters have been evaluated, the manufacturer will assemble the component article into a consumer electronics good and conduct an overall quality assessment, which may include smoke and ignition testing, current leakage testing, and temperature testing, among other things (Ref. 21). At that point, the reworked good is sent for third-party certification. If the substituted component article is considered critical by the certification body, full retesting and recertification of the good may be necessary. Industry commenters anticipate that full retesting and recertification will be required, given the use of PIP (3:1) from a fire safety perspective and the fact that the types of component articles where PIP (3:1) is used play critical roles in the goods. Manufacturers anticipate that this recertification step will take 
anywhere from six to thirty months (Ref. 21). Finally, according to these commenters, a minimum of one year is 
needed to move the newly remanufactured goods throughout the supply chain. This commenter further contended that a chemical phase out in response to a restriction in the European Union under the Restriction on Hazardous Substances (RoHS) 2, a product-level compliance program for electrical and electronic equipment, is typically effective four years from the date of notice by the European Union (Ref. 21). 
The heavy equipment sector provided 
similarly detailed descriptions of the length of time needed to replace PIP (3:1)-containing component articles (Ref. 18). These commenters stated that their design cycles are typically seven years from start to finish, and that this would likely be the amount of time needed to identify whether and to what extent PIP (3:1) exists in the supply chain, confirm the function of PIP (3:1) for the end-use application, identify alternatives, re-design for the alternative rather than PIP (3:1), test the replacement component article for safety, regulatory, and quality requirements, and re-introduce the good into the market (Ref. 18). According to this commenter, the testing requirements often take the longest time to complete during a redesign because heavy-duty industrial equipment operates in demanding and severe operating conditions over a long product life cycle. Such equipment is reportedly subject to various fire safety and flammability regulatory requirements set by the National Highway Traffic Safety Administration (Flammability Test for Motor Vehicle Interiors, 49 CFR 571.302), the Occupational Safety and Health Administration (Fire Protection and Prevention, 29 CFR 1926.24 and 1926.151), the Mine Safety and Health Administration (various fire prevention provisions, including 30 CFR part 35 and 30 CFR 75.1100, 75.1911, and 77.1100), and the Federal Railroad Administration (49 CFR parts 216, 223, 229, 231, 232, 238). Additionally, according to this commenter, engine emission sensors designed for off-road equipment to comply with the Clean Air Act currently rely on PIP (3:1) to survive the high-temperature environment in the engine compartment (Ref. 18). 
A unique problem reported by this 
commenter and several others in the heavy equipment sector is that their supply chains often overlap with much larger industries, such as the automotive and aerospace sectors (Refs. 18, 19, 26, 27, and 28). A recent survey by one 
commenter found that 61% of the surveyed suppliers in the heavy 
VerDate Sep<11>2014 16:49 Oct 27, 2021 Jkt 256001 PO 00000 Frm 00038 Fmt 4702 Sfmt 4702 E:\FR\FM\28OCP1.SGM 28OCP1jspears on DSK121TN23PROD with PROPOSALS159690 Federal Register / Vol. 86, No. 206 / Thursday, October 28, 2021 / Proposed Rules 
equipment sector also provided parts 
and materials to the automotive industry (Ref. 18). According to this commenter, despite the significant overlap in suppliers, there are key differences in the product design lifecycles and volumes between the industries. Heavy-duty, industrial professional use equipment is decidedly lower volume with a higher diversity of goods than those found in the consumer automotive market. As the automotive sector is currently excluded from the January 2021 PIP (3:1) final rule, the current regulations allow suppliers to provide automotive parts that contain PIP (3:1) to their automotive manufacturers. With the higher variability of goods and lower volume nature of the heavy-duty, industrial equipment sector, commenters assert that the manufacturers of this non- automotive equipment will need to utilize custom made parts which, if available, could cost between two and ten times the normal price of the automotive parts that they would ordinarily use (Ref. 28). 
In contrast to the industry 
commenters, who all stated that the March 8, 2021, compliance date for PIP (3:1)-containing articles was not practicable, a comment submitted by three environmental public interest groups in response to EPA’s March 2021 request for comments stated that industry had been given sufficient notice of EPA’s intent to regulate PIP (3:1) in articles and did not believe that EPA should excuse their failure to comment in a timely manner (Ref. 29). This commenter further noted that any exclusions or extended compliance dates should be considered under the stringent criteria of TSCA section 6(g), which requires EPA to determine one of the following: (1) That the condition of use is a critical or essential use with no feasible safer alternatives; or (2) that compliance with a requirement would significantly disrupt the national economy, national security, or critical infrastructure; or (3) that the specific condition of use provides a substantial benefit to health, the environment, or public safety. 
EPA generally agrees with the 
industry commenters on the conceptual steps that may be needed to phase PIP (3:1) out of articles in their supply chains. Industry must first determine where PIP (3:1) is used, identify alternatives to PIP (3:1), and then design, test, and recertify, as necessary, the new articles made without PIP (3:1). Those new articles must then be distributed throughout the supply 
chain. However, EPA observes that these steps need not always be undertaken sequentially. For example, it is not necessary to identify every single model of smartphone that uses a power cord that contains PIP (3:1) before work begins to identify and test alternatives to PIP (3:1) in power cords for smartphones. 
Some commenters provided detailed 
estimates of the time needed to take these steps while others did not. For example, comments from the consumer technology sector gave estimates for completing each one of these steps, with the overall timeline ranging from 2.25 years to 6.5 years (Ref. 21). Estimated timelines provided by commenters in response to the March 2021 notification and request for comments ranged from 2.25 years to 15 years or more (Refs. 21 and 16). Given the varying estimates, and the lack of detail accompanying some of those estimates, EPA is proposing to further extend the compliance dates until October 31, 2024 consistent with the lower end of the estimates provided. This will avoid significant disruption in the supply chains for important articles and will provide the public with regulatory certainty while industry collects and submits additional information to inform whether a further compliance date extension may be necessary for certain industry sectors. EPA will consider any additional information of this kind in the context of the broader rulemaking described in more detail in Unit III.C. 
EPA disagrees with the commenter 
who contended that any compliance date extension should be evaluated under TSCA section 6(g). As noted in response to similar comments on the 2019 proposed rule, ‘‘TSCA section 6(h)(4) directs EPA to issue regulations that reduce exposure to PBT chemicals ‘to the extent practicable,’ not to regulate beyond the point of practicability and then issue [section 6(g)] exemptions that would limit the scope of those regulations’’ (Ref. 30, at p. 44). EPA views this compliance date extension as consistent with this standard, and as discussed in Unit III, with the requirements of TSCA section 6(d) to ensure that the compliance dates are ‘‘as soon as practicable’’ and provide a ‘‘reasonable transition period,’’ because this action is necessary to avoid significant disruption in the supply chains for important articles, such as cellular telephones and the HVACR equipment used to cool people, buildings, and to transport and store COVID–19 vaccines and keep them at the appropriate temperature, not as an excuse for a failure to comment earlier in this rulemaking process. III. Provisions of This Proposed Rule 
A. Establishing a Revised Compliance 
Date 
1. TSCA section 6(d) compliance 
dates and section 6(h) rules. TSCA section 6(d) includes a number of provisions relating to establishment of effective or compliance dates applicable to those rules. Specifically, TSCA section 6(d)(1)(A) directs EPA to specify a date on which the TSCA section 6(a) rule is to take effect that is ‘‘as soon as practicable.’’ TSCA section 6(d)(1)(B) requires EPA to specify mandatory compliance dates for each requirement of a rule promulgated under TSCA section 6(a), which must be as soon as practicable but no later than five years after promulgation except as provided in subsections (C) and (D) or in the case of a use exempted under TSCA section 6(g). TSCA section 6(d)(1)(C) states that EPA must specify mandatory compliance dates for the start of ban or phase-out requirements under a TSCA section 6(a) rule, which must be as soon as practicable but no later than five years after promulgation, except in the case of a use exempted under TSCA section 6(g); and subsection (D) requires EPA to specify mandatory compliance dates for full implementation of ban or phase-out requirements, which must be as soon as practicable. Additionally, TSCA section 6(d)(1)(E) directs EPA to provide for a reasonable transition period. 
As noted in the preamble to the 
January 2021 final rule, the term ‘‘practicable’’ as used in the phrase ‘‘to the extent practicable’’ in TSCA section 6(h) are undefined, the phrases ‘‘as soon as practicable’’ and ‘‘reasonable transition period’’ as used in TSCA section 6(d)(1) are also undefined, and the legislative history on each provision is limited. Given the ambiguity in the statute, for purposes of the final rule under TSCA section 6(h), EPA presumed a 60-day compliance date was ‘‘as soon as practicable’’ where EPA determined a prohibition or restriction was practicable, unless there was support for a lengthier period of time on the basis of reasonably available information, such as information 
submitted in comments on the Exposure and Use Assessment or on the proposed rule, or in stakeholder dialogues. At the time, EPA believed that such a presumption would ensure that the compliance schedule is ‘‘as soon as practicable,’’ particularly in the context of the TSCA section 6(h) rules for chemicals identified as persistent, bioaccumulative and toxic, and given that the expedited timeframe for issuing a TSCA section 6(h) proposed rule did

not allow time for collection and 
assessment of new information separate from the comment opportunities during the development of and in response to the proposed rule. EPA noted that this approach also allows for submission of information from the sources most likely to have the information that would impact an EPA determination on whether or how best to adjust the compliance deadline to ensure that the final compliance deadline chosen is both ‘‘as soon as practicable’’ and provides a ‘‘reasonable transition period.’’ 
Despite significant outreach efforts, 
EPA did not receive timely or specific input from certain stakeholders during any public comment periods prior to issuance of the January 2021 final rule regarding the presence of PIP (3:1) in myriad articles. Absent this input, in the January 2021 final rule EPA determined that PIP (3:1) was not widely present in articles outside the aerospace and automotive sectors and that the presumption that a 60-day compliance date was practicable was appropriate. The comments received in response to EPA’s March 2021 notification and request for comments, and the communications received before that document published in the Federal Register, presented new information 
demonstrating that a 60-day compliance date was not practicable and did not provide a reasonable transition period for the full implementation of a ban or phase-out for many industries (Ref. 14). 
B. Proposed Further Compliance Date 
Extension 
As a result of the comments received 
in response to EPA’s March 2021 notification and request for comments, as well as on information provided during stakeholder meetings since the publication of the January 2021 final rule on PIP (3:1), EPA is proposing that the compliance date for PIP (3:1) and PIP (3:1)-containing articles, but not PIP (3:1)-containing products, should be further extended. EPA is proposing to extend the deadline adopted in the September 2021 final rule from March 8, 2022, to October 31, 2024. EPA has primarily based this proposal on the low 
end of the timelines provided by commenters and the specific, detailed timeline laid out by the consumer electronics sector (Ref. 21). Only two commenters, representing individual companies, stated that they needed less than this amount of time to phase out PIP (3:1) from their articles (Refs. 24 and 25). Many commenters suggested longer timelines, ranging from four to seven to fifteen years or more, although most did not provide sufficient detail to support these timelines. Once the use of PIP (3:1) has been identified in a specific article, the supplier can work with its supply chain to investigate and identify alternatives to the use of PIP (3:1) (Ref. 21). Most commenters indicated that the investigation of substitutes would have to wait until the specific uses are identified (Ref. 18). Commenters also stated that there may be considerable time and expense involved in recertifying commercial and consumer goods to applicable government requirements and industry consensus standards (Ref. 21). EPA is seeking public comment on the compliance deadline in this proposal, including information on the costs and benefits of the proposed compliance date extension, as well as information on exposures arising from PIP (3:1) in articles to improve EPA’s understanding of the impacts of any future rulemaking. 
EPA is also considering the 
opportunity stakeholders will have to provide additional information to support any needed further compliance date extensions for consideration in the subsequent rulemaking activity discussed in Unit III.D. In particular, EPA believes that stakeholders will continue to increase their understanding regarding the presence of PIP (3:1) in articles and potential substitutes for PIP (3:1). EPA anticipates that it will also have more information on PIP (3:1) uses and substitutes, allowing EPA to better describe the kinds of information EPA will use in determining whether further compliance date extensions are warranted or whether compliance dates should be applied to activities currently excluded from the January 2021 final rule. 
While the consumer electronics sector 
and some industry commenters provided detailed information on the steps required to replace PIP (3:1) in their supply chains, along with reasonable estimates of the time needed to complete each of those steps, most did not. As outlined in the March 2021 notification and request for comments, EPA asked for information on: 
•The specific articles that need an 
alternative compliance date; 
•The basis for the alternative 
compliance date, taking into consideration the reasons supporting alternative deadlines in the January 2021 final rule, such as the January 1, 2022, date for photographic printing articles and the January 6, 2025, date for adhesives and sealants, with supporting documentation; and 
•The additional time needed for 
specific articles to clear channels of trade. EPA understands that many industry 
sectors are still attempting to determine 
exactly where PIP (3:1) is present in their supply chains. Nevertheless, to the extent that any industry sector believes that it needs a compliance date beyond October 31, 2024, EPA invites comments providing specific information and documentation supporting a further compliance date extension. EPA will evaluate requests for extensions beyond the October 2024 date by evaluating the level of detail and 
documentation provided by the commenters on: 
•The specific uses of PIP (3:1) in 
articles throughout their supply chains; 
•Concrete steps taken to identify, 
test, and qualify substitutes for those uses, including details on the substitutes tested and the specific certifications that would require updating; 
•Estimates of the time required to 
identify, test, and qualify substitutes with supporting documentation; and 
•Documentation of the specific need 
for replacement parts, which may include the documented service life of the equipment and specific identification of any applicable regulatory requirements for the assurance of replacement parts. 
EPA also requests comment on 
whether these are the appropriate types of information for use in evaluating compliance date extensions, and whether there are other considerations that should apply. 
Finally, while PIP (3:1) for use in 
articles described in 40 CFR 751.407(a)(ii) or (b) will continue to have recordkeeping requirements, EPA proposes to extend the recordkeeping compliance date in 40 CFR 751.407(d) for certain PIP (3:1)-containing articles, until October 31, 2024. Because industry is still in the process of identifying whether and where PIP (3:1) is present in many of the articles in their supply chains, the statement of compliance required in 40 CFR 751.407(d)(2) will not aid EPA in monitoring compliance with the regulation. 
C. Future Rulemaking Activity on PBTs 
under TSCA section 6(h) 
EPA intends to commence a new 
rulemaking effort on PIP (3:1) and the other four chemical substances regulated under TSCA section 6(h) and anticipates issuing a proposal in 2023. As discussed in EPA’s March 2021 notification and request for comments, the Agency is reviewing the provisions of all five of the final rules issued under TSCA section 6(h), evaluating the other applicable provisions of amended 
VerDate Sep<11>2014 16:49 Oct 27, 2021 Jkt 256001 PO 00000 Frm 00040 Fmt 4702 Sfmt 4702 E:\FR\FM\28OCP1.SGM 28OCP1jspears on DSK121TN23PROD with PROPOSALS159692 Federal Register / Vol. 86, No. 206 / Thursday, October 28, 2021 / Proposed Rules 
TSCA, and determining how recent 
Executive Orders and other Administration priorities (Refs. 7, 8, 9, 10, and 11) could be addressed, along with the additional information provided by stakeholders. As part of this process, EPA will address comments received in response to the March 2021 notification and request for comments that are not addressed by the September 2021 final rule extending PIP (3:1) compliance dates and will consider whether additional exposure reductions are practicable for all five of the PBT chemicals. In addition, over the next year, EPA anticipates that many of the industries currently trying to determine whether PIP (3:1) is present in their articles will acquire additional detailed information on the presence of PIP (3:1) in articles and will have begun to identify potential substitutes for those uses. At the time that this broader proposal is issued, to the extent that any industry sector still believes that they 
will not be able to comply with the PIP (3:1) compliance dates established in this rulemaking, EPA plans to invite that industry to provide specific detailed comments and documentation along the lines discussed in Unit III.B. EPA also expects to solicit comment and information on exposures arising from PIP (3:1) in articles to inform EPA’s understanding of the impacts of any future rulemaking. 
As part of the future proposed 
rulemaking, EPA also intends to thoroughly review the justifications underlying the exclusions in the January 2021 PIP (3:1) final rule and the other final rules under TSCA section 6(h) to determine whether to adopt new compliance dates for those activities currently excluded from the January 2021 final rules or to further extend compliance dates that have already been extended, consistent with the statutory directive to reduce exposure to the extent practicable.

A. Executive Order 12866: Regulatory 
Planning and Review and Executive Order 13563: Improving Regulation and Regulatory Review 
This action is a significant regulatory 
action under Executive Order 12866 (58 FR 51735, October 4, 1993) and was submitted to the Office of Management and Budget (OMB) for review under Executive Orders 12866 and 13563 (76 FR 3821, January 21, 2011). Any changes made in response to OMB review have been reflected in the docket for this action. 
B. Paperwork Reduction Act (PRA) 
This action does not impose any new 
information collection activities or 
burden subject to OMB review and approval under the PRA, 44 U.S.C. 3501 et seq. However, this action defers the costs associated with paperwork and recordkeeping burden for an existing information collection because the delayed compliance date alters the time horizon of the collection’s analysis. Burden is defined in 5 CFR 1320.3(b). OMB has previously approved the information collection activities contained in the existing regulations and associated burden under OMB Control No. 2070–0213 (EPA ICR No. 2599.02). An agency may not conduct or sponsor, and a person is not required to respond to a collection of information that requires OMB approval under PRA, unless it has been approved by OMB 
and displays a currently valid OMB control number. The OMB control numbers for EPA’s regulations in title 40 of the CFR, after appearing in the Federal Register, are listed in 40 CFR part 9, and included on the related collection instrument or form, if applicable. 
C. Regulatory Flexibility Act (RFA) 
I certify that this action will not have 
a significant economic impact on a 
substantial number of small entities under the RFA. In making this determination, EPA concludes that the impact of concern for this rule is any significant adverse economic impact on small entities, and the agency is certifying that this rule will not have a significant economic impact on a substantial number of small entities because the rule relieves regulatory burden. This action would extend the compliance date for a prohibition on the processing and distributing in commerce of PIP (3:1) for use in certain articles and the processing and 
distributing in commerce of certain PIP (3:1)-containing articles, along with the associated recordkeeping requirements, from March 8, 2022, to October 31, 2024. EPA has therefore concluded that this action would relieve regulatory burden for all directly regulated small entities. 
D. Unfunded Mandates Reform Act 
(UMRA) 
This action does not contain any 
unfunded mandate as described in UMRA, 2 U.S.C. 1531–1538, and does not significantly or uniquely affect small governments. The action imposes no enforceable duty on any state, local or tribal governments or the private sector. 
E. Executive Order 13132: Federalism 
This action does not have federalism 
implications as specified in Executive 
Order 13132 (64 FR 43255, August 10, 1999). It will not have substantial direct effects on the states, on the relationship between the national government and the states, or on the distribution of power and responsibilities among the various levels of government. 
F. Executive Order 13175: Consultation 
and Coordination With Indian Tribal Governments 
This action does not have tribal 
implications as specified in Executive Order 13175 (65 FR 67249, November 9, 2000) because it does not have substantial direct effects on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes. Thus, Executive Order 13175 does not apply to this action. 
G. Executive Order 13045: Protection of 
Children From Environmental Health Risks and Safety Risks 
This action is not a ‘‘covered 
regulatory action’’ under Executive Order 13045 (62 FR 19885, April 23, 
1997) because it is not an economically significant regulatory action as defined by Executive Order 12866. 
H. Executive Order 13211: Actions 
Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use 
This is not a ‘‘significant energy 
action’’ as defined in Executive Order 13211 (66 FR 28355, May 22, 2001), because it is not likely to have a significant adverse effect on the supply, distribution or use of energy and has not otherwise been designated by the Administrator of the Office of Information and Regulatory Affairs as a significant energy action. 
I. National Technology Transfer and 
Advancement Act (NTTAA) 
This action does not involve technical 
standards. As such, NTTAA section 12(d), 15 U.S.C. 272 note, does not apply to this action. 
J. Executive Order 12898: Federal 
Actions To Address Environmental Justice in Minority Populations and Low-Income Populations 
EPA believes that this action does not 
have disproportionately high and adverse human health or environmental effects on minority populations, low- income populations and/or indigenous peoples, as specified in Executive Order 12898 (59 FR 7629, February 16, 1994). As discussed in Unit II., this action is necessary to avoid widespread disruptions in the supply chains for a wide variety of essential goods and would not otherwise materially alter the final rule as published. 
List of Subjects in 40 CFR Part 751 
Environmental protection, Chemicals, 
Export notification, Hazardous 
substances, Import certification, Reporting and recordkeeping. 
Michael S. Regan, 
Administrator. 
Therefore, for the reasons stated in the 
preamble, EPA proposes to amend 40 
CFR part 751 as follows: 
PART 751—REGULATION OF CERTAIN 
CHEMICAL SUBSTANCES AND MIXTURES UNDER SECTION 6 OF THE TOXIC SUBSTANCES CONTROL ACT 
■1. The authority citation for part 751 
continues to read as follows: 
Authority: 15 U.S.C. 2605, 15 U.S.C. 
2625(l)(4). 
§ 751.407 [Amended] 
■2. Amend § 751.407 in paragraphs 
(a)(2)(iii) and (d)(4) by removing ‘‘March 
8, 2022’’ and adding ‘‘October 31, 2024’’ in its place.
