(SACC) Meeting; Notice of Availability, Public Meeting, 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 Methylene Chloride (MC). The purpose of the risk 
evaluation process under TSCA is to determine, upon issuance of a final 
risk evaluation, 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. 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.

DATES: 
    Virtual Meeting: The preparatory virtual meeting will be held on 
November 12, 2019, from 1:00 p.m. to approximately 4:00 p.m. (EST). You

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 these draft risk evaluations, 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,

[[Page 57867]]

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 on 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 substances 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 draft risk evaluation and the outcome of the systematic 
review associated with the chemical substances. 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 
dockets 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 these chemicals are part of the first ten chemical 
substances undergoing risk evaluation, these chemical substances were 
not required to go through prioritization (81 FR 91927, December 19, 
2016) (FRL-9956-47). The purpose of risk evaluation 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 MC?

    Methylene chloride (MC), also known as dichloromethane and DCM, is 
a volatile chemical used as a solvent in a wide range of industrial, 
commercial and consumer applications. The primary uses for methylene 
chloride are for paint removal, adhesives, pharmaceutical 
manufacturing, metal cleaning, aerosol solvents, chemical

[[Page 57868]]

processing and flexible polyurethane foam manufacturing. Information 
from the 2016 Chemical Data Reporting (CDR) for MC indicates the 
reported production volume is more than 260 million lbs/year 
(manufacture and import).
    Information about the problem formulation and scope phases of the 
TSCA risk evaluation for this chemical is available at http://www.epa.gov/assessing-and-managing-chemicals-under-tsca/risk-evaluation-methylene-chloride-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 
substances. 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 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 meeting 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.
