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, 15 U.S.C. 2601 et seq., (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?
The draft scope of the risk evaluation is issued pursuant to TSCA
section 6(b) and TSCA implementing regulations at 40 CFR 702.41(c)(7).
C. What action is the Agency taking?
EPA is publishing and requesting public comment on the draft scope
of the Risk Evaluation under TSCA for Asbestos Part 2: Supplemental
Evaluation Including Legacy Uses and Associated Disposals of Asbestos.
Through the risk evaluation process, EPA will determine whether the
chemical substance presents an unreasonable risk of injury to health or
the environment under the conditions of use, as determined by the
Administrator, in accordance with TSCA section 6(b)(4).
II. Background
Following EPA's June 2016 designation of Asbestos as one the first
ten chemicals to undergo risk evaluation under TSCA, EPA initially
focused the risk evaluation for asbestos on chrysotile asbestos as this
is the only asbestos fiber type that is currently imported, processed,
or distributed in the U.S. However, in late 2019, the court in Safer
Chemicals, Healthy Families v. EPA, 943 F.3d 397 (9th Cir. 2019) held
that EPA's Risk Evaluation Rule (82 FR 33726, July 20, 2017) (FRL-9964-
38) and codified at 40 CFR part 702, subpart B, should not have
excluded ``legacy uses'' (i.e., uses without ongoing or prospective
manufacturing, processing, or distribution) or ``associated disposals''
(i.e., future disposal of legacy uses) from the definition of
conditions of use, although the court did uphold EPA's exclusion of
``legacy disposals'' (i.e., past disposal). Following this court
ruling, EPA continued development of the risk evaluation focused on
chrysotile asbestos and determined that the complete risk evaluation
for asbestos would be issued in two parts. The Risk Evaluation for
Asbestos Part 1: Chrysotile Asbestos was released in December 2020 (86
FR 89, January 4, 2021) (FRL-10017-47), allowing the Agency to
expeditiously move into risk management for the unreasonable risk
identified in Part 1. Under the consent decree in the case Asbestos
Disease
[[Page 74089]]
Awareness Organization et al v. Regan et al, 4:21-cv-03716 (N.D. Cal.)
EPA is required to publish a final Part 2 Risk Evaluation for Asbestos
on or before December 1, 2024. The draft scope of the Risk Evaluation
for Asbestos Part 2 is the subject of this notice.
The purpose of a risk evaluation is to determine whether a chemical
substance, or group of chemical substances, 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 hazards and exposures for the
conditions of use; describe whether aggregate or sentinel exposures
were considered and the basis for consideration; not consider costs or
other non-risk factors; take into account where relevant, likely
duration, intensity, frequency, and number of exposures; and describe
the weight-of-scientific-evidence for hazards and exposures (15 U.S.C.
2605(b)(4)(F)). 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 (15
U.S.C. 2605(b)(4)(A); 40 CFR 702.47).
III. Draft Scope of the Risk Evaluation for Asbestos Part 2:
Supplemental Evaluation Including Legacy Uses and Associated Disposals
of Asbestos
EPA is publishing the draft scope of the Risk Evaluation for
Asbestos Part 2: Supplemental Evaluation Including Legacy Uses and
Associated Disposals of Asbestos. For the purposes of scoping and risk
evaluation, EPA has adopted the definition of asbestos as defined by
TSCA Title II (added to TSCA in 1986), Section 202 as the ``asbestiform
varieties of six fiber types--chrysotile (serpentine), crocidolite
(riebeckite), amosite (cummingtonite-grunerite), anthophyllite,
tremolite or actinolite.'' The latter five fiber types are amphibole
varieties. Given that Part 2 of the risk evaluation will focus on
legacy uses of asbestos and associated disposals, a unique
consideration will be vermiculite, which was widely used in building
materials in the past and was co-located with Libby Amphibole Asbestos
(LAA; and its tremolite, winchite, and richterite constituents). Thus,
LAA (and its tremolite, winchite, and richterite constituents) will be
considered in Part 2 of the risk evaluation. Additionally, another
commercially mined substance, talc, has been implicated as a potential
source of asbestos exposure. Talc can also be co-located geologically
with asbestos, where asbestos can remain in small or trace amounts
following extraction. Thus, EPA will determine the relevant conditions
of use of talc, including but not limited to any ``legacy use'' and
``associated disposal'', where asbestos is implicated. The draft scope
of the risk evaluation for this asbestos Part 2 includes the conditions
of use, hazards, exposures, and the potentially exposed or susceptible
subpopulations EPA plans to consider in the risk evaluation (15 U.S.C.
2605(b)(4)(D)). Development of the scope is the first step of a risk
evaluation. The draft scope of the risk evaluation will include the
following components (40 CFR 702.41(c)):
<bullet> The conditions of use, as determined by the Administrator,
that EPA plans to consider in the risk evaluation.
<bullet> The potentially exposed populations that EPA plans to
evaluate; the ecological receptors that EPA plans to evaluate; and the
hazards to health and the environment that EPA plans to evaluate.
<bullet> A description of the reasonably available information and
the science approaches that the Agency plans to use.
<bullet> A conceptual model that will describe 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, to release or disposal--and identification of
human and ecological health hazards EPA plans to evaluate for the
exposure scenarios EPA plans to evaluate.
<bullet> An analysis plan, which will identify 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.
<bullet> A plan for peer review.
EPA encourages commenters to provide information they believe might
be missing or may further inform the risk evaluation.
Authority: 15 U.S.C. 2601 et seq.
Michael S. Regan,
Administrator.
