Trichloroethylene; Draft Toxic Substances Control Act (TSCA) Risk 
Evaluation and TSCA Science Advisory Committee on Chemicals (SACC) 
Meetings; Notice of Availability, Public Meetings, and Request for 
Comment

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: EPA is announcing the availability of and soliciting public 
comment on the draft Toxic Substances Control Act (TSCA) risk 
evaluation of trichloroethylene (TCE). 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 an in-person public 
meeting of the TSCA SACC to consider and review the draft risk 
evaluation. Preceding the in-person meeting, there will be a 
preparatory virtual public meeting for the panel to consider the scope 
and clarity of the draft charge questions for the peer review. 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.

SUPPLEMENTARY INFORMATION: 

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 exposed 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 
supported 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 part 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

[[Page 11081]]

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 trichloroethylene?

    Trichloroethylene (TCE) has a wide-range of uses in consumer and 
commercial products and in industry. An estimated 84% of TCE's annual 
production volume is used as an intermediate in the manufacture of the 
hydrofluorocarbon HFC-134a. Another 15% of TCE production volume is 
used as a degreasing solvent, leaving approximately 1% for other uses. 
The total aggregate production volume decreased from 220.5 to 171.9 
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-trichloroethylene-tce-0.

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.
