SUPPLEMENTARY INFORMATION : 
I. General Information 
A. Does this action apply to me? 
This action is directed to the public 
in general and may be of interest to 
entities that manufacture (including import) a chemical substance regulated under TSCA (e.g., entities identified 
under North American Industrial Classification System (NAICS) codes 325 and 324110). The action may also be of interest to chemical processors, distributors in commerce, and users; 
non-governmental organizations in the environmental and public health sectors; state and local government agencies; and members of the public. Since other entities may also be interested, the Agency has not attempted to describe all the specific entities and corresponding NAICS codes for entities that may be interested in or affected by this action. 
B. What is the Agency’s authority for 
taking this action? 
This action directly implements 
TSCA section 6(b)(4)(D), 15 U.S.C. 
2605(b)(4)(D). 
C. What action is the Agency taking? 
EPA is announcing the availability of 
the final scope documents of the risk 
evaluations for the 20 chemical substances designated as High-Priority Substances for risk evaluation under TSCA. Through the risk evaluation process, EPA will determine whether the chemical substances present an unreasonable risk of injury to health or the environment under the conditions of use, in accordance with TSCA section 6(b)(4). 
II. Background 
TSCA section 6(b)(1) requires EPA to 
prioritize chemical substances for risk 
evaluation (15 U.S.C. 2605(b)(1)). Effective December 20, 2019, EPA designated 20 chemical substances as High-Priority Substances for risk evaluation (Ref. 1), which initiated the risk evaluation process for those chemical substances (15 U.S.C. 2605(b)(3)(A); 40 CFR 702.17). The purpose of risk evaluation is to determine whether a chemical substance presents an unreasonable risk to health or the environment, under the conditions of use, including an unreasonable risk to a relevant potentially exposed or susceptible subpopulation (15 U.S.C. 2605(b)(4)(A)). As part of this process, EPA must evaluate both hazard and exposure, exclude consideration of costs or other non-risk factors, use scientific information and approaches in a manner that is consistent with the requirements in TSCA for the best available science, and ensure decisions are based on the weight-of-scientific- evidence (15 U.S.C. 2605(b)(4)(F), 2625(h) and (i)). This process will culminate in a determination of whether or not the chemical substance presents an unreasonable risk of injury to health or the environment under the conditions of use (40 CFR 702.47). 
Pursuant to 40 CFR 702.41(c)(7), EPA 
announced the availability of and

sought public comment on the draft 
scope documents for the risk evaluations to be conducted for 13 of 20 High-Priority Substances under TSCA (85 FR 19941, April 9, 2020) (FRL– 10007–11) (Ref. 2) and the remaining 7 of 20 High-Priority Substances under TSCA (85 FR 22733, April 23, 2020) (FRL–10008–05) (Ref. 3). 
III. Information and Comments 
Received 
A. Overview of Public Comments 
Comments were received during two 
45-day comment periods following the 
announcement of the draft scope documents for the risk evaluations to be conducted for 13 of 20 High-Priority Substances under TSCA (Ref. 2) and the remaining 7 of 20 High-Priority Substances under TSCA (Ref. 3). During both comment periods, the public was invited to submit comments on EPA’s draft scope documents, including additional data or information relevant to the chemical substances or that otherwise could be useful to the Agency in finalizing the scope of the risk evaluations. To the extent that comments provided information on conditions of use, as well as other elements of the draft scope documents, those comments and other submitted information (e.g., relevant studies and assessments) were used to inform 
revisions to the draft scope documents and may be considered in subsequent phases of the risk evaluation process. 
EPA created one general docket to 
receive comments regarding the risk evaluation process and additional, individual dockets on each of the 20 High-Priority Substances undergoing risk evaluation to receive chemical- specific information. From all 21 dockets, EPA received 245 submissions; however, some commenters opted for one submission describing all their comments and submitted it to multiple dockets, other commenters chose to submit different comments to specific chemical-specific dockets, and some commenters did both. Therefore, EPA considered 78 of those submissions unique. EPA received submissions from 66 different entities, including potentially affected businesses or trade associations, environmental and public health advocacy groups and academia (some submissions were signed by more than one group), a group of state attorneys general, and other organizations. 
Comments addressed the overall 
approach to the risk evaluation process 
(e.g., collection, consideration, and 
systematic review of relevant information), the specific elements of the scope documents (e.g., hazard, exposure, and potentially exposed or 
susceptible subpopulations (PESS)), information specific to the chemical substances (e.g., relevant studies, 
assessments, and conditions of use (COUs)), and topics beyond the draft scope document phase of the process (e.g., risk management). One comment 
(EPA–HQ–2018–0465–0028) was not related to the risk evaluation of the 20 High-Priority Substances. EPA considered those comments, as applicable and appropriate, in developing the final scope documents. Concurrently with the publication of the 20 final scope documents, EPA is publishing a response to comments document that contains a comprehensive summary of and response to public comments received on the 20 draft scope documents. The comprehensive response to comments document is available in the docket EPA–HQ–OPPT–2019–0131 (Ref. 4).

The final scope document for the risk 
evaluation for each of these 20 chemical 
substances includes the conditions of use, hazards, exposures, and the potentially exposed or susceptible subpopulations EPA plans to consider. Development of the scope is the first step of a risk evaluation. The final scope document for each risk evaluation 
includes the following components (40 CFR 702.41(c)): 
•The conditions of use, as 
determined by the Administrator, that 
EPA plans to consider in the risk evaluation. 
•The potentially exposed 
populations that EPA plans to evaluate; the ecological receptors EPA plans to 
evaluate; and the hazards to health and the environment that EPA plans to evaluate. 
•A description of the reasonably 
available information and the science approaches that the Agency plans to use. 
VerDate Sep<11>2014 16:42 Sep 03, 2020 Jkt 250001 PO 00000 Frm 00031 Fmt 4703 Sfmt 4703 E:\FR\FM\04SEN1.SGM 04SEN1jbell on DSKJLSW7X2PROD with NOTICES55283 Federal Register / Vol. 85, No. 173 / Friday, September 4, 2020 / Notices 
•A conceptual model that describes 
the actual or predicted relationships 
between the chemical substance, the conditions of use within the scope of the evaluation and the receptors, either human or environmental, with consideration of the life cycle of the chemical substance—from manufacturing, processing, distribution in commerce, storage, use, and disposal—and identification of human and ecological health hazards EPA plans to evaluate for the exposure scenarios EPA plans to evaluate. 
•An analysis plan, which identifies 
the approaches and methods EPA plans to use to assess exposure, hazards, and risk, including associated uncertainty and variability, as well as a strategy for using reasonably available information and science approaches. 
•A plan for peer review. 
Based on public comments received, 
the Agency was able to update conditions of use presented in the draft scope documents and accept additional data or information from stakeholders that was useful to the Agency in finalizing the scope of the risk evaluations. In addition, public comments were considered to better inform the exposure pathways, routes, 
receptors, PESS, and hazards that EPA plans to consider in the risk evaluations for the 20 High-Priority Substances. Note that, as a result of the Ninth Circuit Court of Appeals’ decision in Safer Chemicals, Healthy Families v. U.S. 
EPA, 943 F.3d 397, 425 (9th Cir. 2019), 
EPA will no longer exclude legacy uses or associated disposal from the definition of ‘‘conditions of use.’’ Rather, when these activities are intended, known, or reasonably foreseen, these activities will be considered uses and disposal, respectively, within the definition of ‘‘conditions of use.’’

ACTION : Notice. 
SUMMARY : As required by the final rule 
on fees for the administration of the Toxic Substances Control Act (TSCA) (the Fees Rule), in which the Environmental Protection Agency (EPA) established fees to defray some of the costs of administering certain provisions of TSCA, EPA this document announces the availability of the final lists identifying the manufacturers (including importers) of the 20 chemical substances that have been designated as a High-Priority Substance for risk evaluation and for which fees will be charged. In January 2020, EPA announced the availability of and solicited public comment on the preliminary lists identifying manufacturers subject to fee obligations for EPA-initiated risk evaluations under TSCA. During the comment period, which closed on June 15, 2020, manufacturers (including importers) were also required to self-identify as a manufacturer of one of the 20 High- Priority Substances irrespective of whether they are included on the preliminary lists. Where appropriate, entities had the opportunity to avoid or reduce fee obligations by making certain certifications consistent with the Fees Rule.
