Environmental Protection Agency (EPA).
EPA is announcing the availability of and soliciting public comment on the draft Toxic Substances Control Act (TSCA) risk evaluation of perchloroethylene. EPA is also submitting the same document to the TSCA Science Advisory Committee on Chemicals (SACC) for peer review and is announcing that there will be two virtual public meetings of the TSCA SACC, with participation by phone and webcast only, and no in-person gathering. The first virtual public meeting will be a preparatory meeting for the SACC to consider the scope and clarity of the draft charge questions for the peer review. This will be followed by the peer review public virtual meeting for the SACC to consider and review the draft risk evaluation. The purpose of conducting risk evaluations under TSCA is to determine whether a chemical substance presents an unreasonable risk of injury to health or the environment under the conditions of use, including an unreasonable risk to a relevant potentially exposed or susceptible subpopulation.
Preparatory Virtual Meeting: Will be held on May 5, 2020, from 1:00 p.m. to approximately 4:00 p.m. (EDT).

I. General Information
A. Does this action apply to me?
This action is directed to the public in general. This action may be of interest to persons who are or may be required to conduct testing and those interested in risk evaluations of chemical substances under TSCA, 15 U.S.C. 2601 et seq. Since other entities may also be interested in this draft risk evaluation, the EPA has not attempted to describe all the specific entities that may be affected by this action.
B. What is EPA's authority for taking this action?
TSCA section 6, 15 U.S.C. 2605, requires EPA to conduct risk evaluations to “determine whether a chemical substance presents an unreasonable risk of injury to health or the environment, without consideration of costs or other nonrisk factors, including an unreasonable risk to a potentially exposed or susceptible subpopulation identified as relevant to the risk evaluation by the Administrator, under the conditions of use.” 15 U.S.C. 2605(b)(4)(A). TSCA sections 6(b)(4)(A) through (H) enumerate the deadlines and minimum requirements applicable to this process, including provisions that provide instruction on chemical substances that must undergo evaluation, the minimum components of a TSCA risk evaluation, and the timelines for public comment and completion of the risk evaluation. TSCA also requires that EPA operate in a manner that is consistent with the best available science, make decisions based on the weight of the scientific evidence and consider reasonably available information. 15 U.S.C. 2625(h), (i), and (k).
The statute identifies the minimum components for all chemical substance risk evaluations. For each risk evaluation, EPA must publish a document that outlines the scope of the risk evaluation to be conducted, which includes the hazards, exposures, conditions of use, and the potentially Start Printed Page 26465exposed or susceptible subpopulations that EPA expects to consider. 15 U.S.C. 2605(b)(4)(D). The statute further provides that each risk evaluation must also: (1) Integrate and assess available information on hazards and exposures for the conditions of use of the chemical substance, including information that is relevant to specific risks of injury to health or the environment and information on relevant potentially exposed or susceptible subpopulations; (2) describe whether aggregate or sentinel exposures were considered and the basis for that consideration; (3) take into account, where relevant, the likely duration, intensity, frequency, and number of exposures under the conditions of use; and (4) describe the weight of the scientific evidence for the identified hazards and exposures. 15 U.S.C. 2605(b)(4)(F)(i)-(ii) and (iv)-(v). Each risk evaluation must not consider costs or other nonrisk factors. 15 U.S.C. 2605(b)(4)(F)(iii).
The statute requires that the risk evaluation process last no longer than three years, with a possible additional six-month extension. 15 U.S.C. 2605(b)(4)(G). The statute also requires that the EPA allow for no less than a 30-day public comment period on the draft risk evaluation, prior to publishing a final risk evaluation. 15 U.S.C. 2605(b)(4)(H).
C. What action is EPA taking?
EPA is announcing the availability of and seeking public comment on the draft risk evaluation of the chemical substance identified in Unit II. EPA is seeking public comment on all aspects of the draft risk evaluation, including any preliminary conclusions, findings, and determinations, and the submission of any additional information that might be relevant to the draft risk evaluation, including the science underlying the risk evaluation and the outcome of the systematic review associated with the chemical substance. This 60-day comment period on the draft risk evaluation satisfies TSCA section 6(b)(4)(H), which requires EPA to “provide no less than 30 days public notice and an opportunity for comment on a draft risk evaluation prior to publishing a final risk evaluation” and 40 CFR 702.49(a), which states that “EPA will publish a draft risk evaluation in the Federal Register, open a docket to facilitate receipt of public comment, and provide no less than a 60-day comment period, during which time the public may submit comment on EPA's draft risk evaluation.” In addition to any new comments on the draft risk evaluation, the public should resubmit or clearly identify any previously filed comments, modified as appropriate, that are relevant to the draft risk evaluation and that the submitter feels have not been addressed. EPA does not intend to respond to comments submitted prior to the release of the draft risk evaluation unless they are clearly identified in comments on the draft risk evaluation.
EPA is also submitting the draft risk evaluation and associated supporting documents to the TSCA SACC for peer review and announcing the meeting for the peer review panel. All comments submitted to the docket on the draft risk evaluation by the deadline identified in the DATES section will be provided for consideration to the TSCA SACC peer review panel, which will have the opportunity to consider the comments during its discussions.
D. What should I consider as I prepare my comments for EPA?
1. Submitting CBI. Do not submit this information to EPA through regulations.gov or email. Clearly mark the part or all of the information that you claim to be CBI. For CBI information in a disk or CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM as CBI and then identify electronically within the disk or CD-ROM the specific information that is claimed CBI. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2.
2. Tips for preparing your comments. When preparing and submitting your comments, see the commenting tips at http://www.epa.gov/dockets/comments.html.
II. Draft TSCA Risk Evaluation
A. What is EPA's risk evaluation process for existing chemicals under TSCA?
The risk evaluation process is the second step in EPA's existing chemical process under TSCA, following prioritization and before risk management. As this chemical is one of the first ten chemical substances undergoing risk evaluation, the chemical substance was not required to go through prioritization (81 FR 91927, December 19, 2016) (FRL-9956-47). The purpose of conducting risk evaluations is to determine whether a chemical substance presents an unreasonable risk of injury to health or the environment, under the conditions of use, including an unreasonable risk to a relevant potentially exposed or susceptible subpopulation. As part of this process, EPA must evaluate both hazard and exposure, not consider costs or other nonrisk factors, use reasonably available information and approaches in a manner that is consistent with the requirements in TSCA for the use of the best available science, and ensure decisions are based on the weight of scientific evidence.
The specific risk evaluation process that EPA has established by rule to implement the statutory process is set out in 40 CFR part 702 and summarized on EPA's website at http://www.epa.gov/assessing-and-managing-chemicals-under-tsca/risk-evaluations-existing-chemicals-under-tsca. As explained in the preamble to EPA's final rule on procedures for risk evaluation (82 FR 33726, July 20, 2017) (FRL-9964-38), the specific regulatory process set out in 40 CFR part 702, subpart B will be followed for the first ten chemical substances undergoing risk evaluation to the maximum extent practicable.
B. What is perchloroethylene?
Perchloroethylene has a wide range of uses, including production of fluorinated compounds, and as a solvent in dry cleaning and vapor degreasing. A variety of consumer and commercial products use perchloroethylene such as adhesives (arts and crafts, as well as light repairs), aerosol degreasing, brake cleaners, aerosol lubricants, sealants, stone polish, stainless steel polish and wipe cleaners. Perchloroethylene is subject to federal and state regulations and reporting requirements. Leading applications of perchloroethylene include manufacturing, solvents for cleaning and degreasing, lubricants, adhesives and sealants, cleaning and furniture care products. EPA evaluated the conditions of use associated with the manufacturing, processing, distribution in commerce, industrial, commercial and consumer use and disposal of perchloroethylene. The yearly aggregate production volume ranged from 388 to 324 million pounds between 2012 and 2015.
Information about the problem formulation and scope phases of the TSCA risk evaluation for this chemical is available at https://www.epa.gov/assessing-and-managing-chemicals-under-tsca/risk-evaluation-perchloroethylene.

III. TSCA SACC
A. What is the purpose of the TSCA SACC?
The TSCA SACC was established by EPA in 2016 and operates in accordance with the Federal Advisory Committee Act (FACA), 5 U.S.C. Appendix 2 et seq. The TSCA SACC provides expert independent scientific advice and consultation to the EPA on the scientific and technical aspects of risk assessments, methodologies, and pollution prevention measures and approaches for chemicals regulated under TSCA.
The TSCA SACC is comprised of experts in: Toxicology; human health and environmental risk assessment; exposure assessment; and related sciences (e.g., synthetic biology, pharmacology, biotechnology, nanotechnology, biochemistry, biostatistics, physiologically based pharmacokinetic modelling (PBPK) modeling, computational toxicology, epidemiology, environmental fate, and environmental engineering and sustainability). When needed, the committee will be assisted in their reviews by ad hoc participants with specific expertise in the topics under consideration.
B. How can I access the TSCA SACC documents?
EPA's background documents, related supporting materials, and draft charge questions to the TSCA SACC are available on the TSCA SACC website and in the docket established for the specific chemical substance. In addition, EPA will provide additional background documents (e.g., TSCA SACC members participating in this meeting and the meeting agenda) as the materials become available. You may obtain electronic copies of these documents, and certain other related documents that might be available, in the docket at http://www.regulations.gov and the TSCA SACC website at http://www.epa.gov/tsca-peer-review.
After the public meeting, the TSCA SACC will prepare meeting minutes summarizing its recommendations to the EPA. The meeting minutes will be posted on the TSCA SACC website and in the relevant docket.
C. What do I need to know about the TSCA SACC public meetings?
The focus of the public meetings is to peer review EPA's draft risk evaluation. After the peer review process, EPA will consider peer reviewer comments and recommendations and public comments, in finalizing the risk evaluation. The draft risk evaluation contains: Discussion of chemistry and physical-chemical properties; characterization of conditions of use; environmental fate and transport assessment; human health exposures; environmental hazard assessment; risk characterization; risk determination; and a detailed description of the systematic review process developed by the Office of Pollution Prevention and Toxics to search, screen, and evaluate scientific literature for use in the risk evaluation process.
