IV. What is the Agency’s authority for
taking this action?
Section 6(f)(1) of FIFRA (7 U.S.C.
136d(f)(1)) provides that a registrant of
a pesticide product may at any time
request that any of its pesticide
registrations be canceled or amended to
terminate one or more uses. FIFRA
further provides that, before acting on
the request, EPA must publish a notice
of receipt of any such request in the
Federal Register.
Section 6(f)(1)(B) of FIFRA (7 U.S.C.
136d(f)(1)(B)) requires that before acting
on a request for voluntary cancellation,
EPA must provide a 30-day public
comment period on the request for
voluntary cancellation or use
termination. In addition, FIFRA section
6(f)(1)(C) (7 U.S.C. 136d(f)(1)(C))
requires that EPA provide a 180-day
comment period on a request for
voluntary cancellation or termination of
any minor agricultural use before
granting the request, unless:
1. The registrants request a waiver of
the comment period, or
2. The EPA Administrator determines
that continued use of the pesticide
would pose an unreasonable adverse
effect on the environment.
Since difenacoum is not registered for
minor agricultural use, the provision for
a 180-day comment period does not
apply. Accordingly, EPA will provide a
30-day comment period on the proposed
requests.
V. Procedures for Withdrawal of
Requests
Registrants who choose to withdraw a
request for product cancellation or use
deletion should submit the withdrawal
VerDate Sep<11>2014
16:38 Jun 13, 2018
Jkt 244001
in writing to the person listed under FOR
If the
products have been subject to a previous
cancellation action, the effective date of
cancellation and all other provisions of
any earlier cancellation action are
controlling.
FURTHER INFORMATION CONTACT.
VI. Provisions for Disposition of
Existing Stocks
Existing stocks are those stocks of
registered pesticide products that are
currently in the United States and that
were packaged, labeled, and released for
shipment prior to the effective date of
the action. If the requests for voluntary
cancellation are granted, the Agency
intends to publish the cancellation
order in the Federal Register.
In any order issued in response to
these requests for cancellation of
product registrations, EPA proposes to
include the following provisions for the
treatment of any existing stocks of the
products listed in Table 1 of Unit III.
For these voluntary product
cancellations, the registrant will be
permitted to sell and distribute existing
stocks of voluntarily canceled products
until October 18, 2019, which is two
years from the date of the 90-day
response to the GDCI, as requested by
the registrant. Thereafter, the registrant
will be prohibited from selling or
distributing the products identified in
Table 1 of Unit III., except for export
consistent with FIFRA section 17
(7 U.S.C. 136o) or for proper disposal.
Persons other than the registrant may
sell, distribute, or use existing stocks of
canceled products until supplies are
exhausted, provided that such sale,
distribution, or use is consistent with
the terms of the previously approved

Ortho-Phthalaldehyde; Receipt of
Application for Emergency Exemption,
Solicitation of Public Comment
Environmental Protection
Agency (EPA).
ACTION: Notice.
AGENCY:
EPA has received a specific
exemption request from the National
Aeronautics and Space Administration
(NASA) to use the pesticide orthophthalaldehyde (OPA) (CAS No. 643–
79–8) to treat the coolant fluid of the
internal active thermal control system of
the International Space Station to
control aerobic/microaerophilic bacteria
in the aqueous coolant. The applicant
proposes the use of a chemical which is
not registered by EPA. Accordingly, as
required by the Code of Federal
Regulations, EPA is publishing this
notice of receipt to allow public
comment.
DATES: Because of the long lead time
required for acquiring and sending
products to the International Space
Station (ISS), and because this is a
SUMMARY:

repeat of a previously-approved
emergency exemption request, EPA has
approved NASA’s request in advance of
publication of this Notice in accordance
with 40 CFR 166.24(c). Accordingly,
there is no prescribed period for
submitting comments. EPA still
welcomes public comment on the
request, and notes that EPA’s
regulations provide that an emergency
exemption may be modified or revoked
if, among other things, additional
information indicates that the product
may cause unreasonable adverse effects
or may not be effective at controlling the
target pests. Accordingly, the Agency
will review all comments received in
response to this Notice, and consider
whether any such comments identify a
need for modification or revocation of
the specific exemption.

types of entities not listed could also be
affected.
B. What should I consider as I prepare
my comments for EPA?
1. Submitting CBI. Do not submit this
information to EPA through
www.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

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
https://www.epa.gov/dockets/
commenting-epa-dockets.
3. Environmental justice. EPA seeks to
achieve environmental justice, the fair
treatment and meaningful involvement
of any group, including minority and/or
low-income populations, in the
development, implementation, and
enforcement of environmental laws,
regulations, and policies. To help
address potential environmental justice
issues, the Agency seeks information on
any groups or segments of the
population who, as a result of their
location, cultural practices, or other
factors, may have atypical or
disproportionately high and adverse
human health impacts or environmental
effects from exposure to the pesticide(s)
discussed in this document, compared
to the general population.
II. What action is the Agency taking?
Under section 18 of the Federal
Insecticide, Fungicide, and Rodenticide
Act (FIFRA) (7 U.S.C. 136p), at the
discretion of the EPA Administrator, a
Federal or State agency may be
exempted from any provision of FIFRA
if the EPA Administrator determines
that emergency conditions exist which
require the exemption. NASA has
requested the EPA Administrator to
issue a specific exemption for the use of
ortho-phthalaldehyde (OPA) in the
coolant of the internal active thermal
control system (IATCS) of the
International Space Station (ISS) to
control aerobic/microaerophilic bacteria
in the aqueous coolant. Information in
PO 00000
Frm 00019
Fmt 4703
Sfmt 4703
27767
accordance with 40 CFR part 166 was
submitted as part of this request.
As part of this request, the applicant
stated that it has considered the
registered biocide alternatives and has
concluded that OPA is the most
effective biocide which meets the
requisite criteria including: The need for
safe, non-intrusive implementation and
operation in a functioning system; the
ability to control existing planktonic
and biofilm-residing micro-organisms; a
negligible impact on system-wetted
materials of construction; and a
negligible reactivity with existing
coolant additives. The ISS would not
have an adequate long-term solution for
controlling the micro-organisms in the
IATCS coolant without the use of OPA.
The OPA is incorporated into a porous
resin material contained in a stainlesssteel canister. The canister containing
the OPA-incorporated resin is inserted
into a coolant system loop, using
flexible hose and quick disconnects, and
is placed in-line for 8 hours to deliver
the OPA into the fluid. As the coolant
fluid flows through the canister, the
OPA elutes from the resin material into
the coolant fluid. The total volume of
the circulatory loops of the IATCS is
829 liters. The maximum concentration
would be 500 mg of OPA per liter of
coolant fluid. A total of 414,500 mg of
OPA would be needed for the entire
system. The OPA is incorporated into
the resin at 210 mg OPA per cm3 resin,
resulting in a potential total use of 1,974
cm3 of the OPA-containing resin. The
level of OPA in the coolant is monitored
periodically, and because OPA degrades
over time, the concentration decreases
to a level that is no longer effective in
about 1 to 2 years. At this point,
replenishment with new OPAcontaining canisters is required. EPA
has authorized similar emergency
exemptions for this use since 2011.
With the decision to extend the mission
of the ISS to 2024, the need for this use
is expected to continue for the duration.
Previous notices of applications for
emergency exemptions for this same use
of OPA in the ISS IATCS have not
elicited significant substantive
comment. Owing to NASA’s need for an
expedited decision, the negligible
human and environmental exposures
expected from the proposed emergency
use, and the absence of registered
alternatives that meet the ISS IATCS
criteria, EPA has approved this
emergency exemption request prior to
receipt of public comments, consistent
with 40 CFR 166.24(c). EPA’s
regulations provide that an emergency
exemption may be modified or revoked
if, among other things, additional
information indicates that the product
E:\FR\FM\14JNN1.SGM

may cause unreasonable adverse effects
or may not be effective at controlling the
target pests. Accordingly, EPA still
welcomes comments on this request and
will review all comments received in
response to this Notice, and consider
whether any such comments identify a
need for modification or revocation of
the specific exemption.

Under section 18 of the Federal Insecticide, Fungicide, and
Rodenticide Act (FIFRA) (7 U.S.C. 136p), at the discretion of the EPA
Administrator, a Federal or State agency may be exempted from any
provision of FIFRA if the EPA Administrator determines that emergency

monitored periodically, and because OPA degrades over time, the
concentration decreases to a level that is no longer effective in about
1 to 2 years. At this point, replenishment with new OPA-containing
canisters is required. EPA has authorized similar emergency exemptions
for this use since 2011. With the decision to extend the mission of the
ISS to 2024, the need for this use is expected to continue for the
duration.
Previous notices of applications for emergency exemptions for this
same use of OPA in the ISS IATCS have not elicited significant
substantive comment. Owing to NASA's need for an expedited decision,
the negligible human and environmental exposures expected from the
proposed emergency use, and the absence of registered alternatives that
meet the ISS IATCS criteria, EPA has approved this emergency exemption
request prior to receipt of public comments, consistent with 40 CFR
166.24(c). EPA's regulations provide that an emergency exemption may be
modified or revoked if, among other things, additional information
indicates that the product

may cause unreasonable adverse effects or may not be effective at
controlling the target pests. Accordingly, EPA still welcomes comments
on this request and will review all comments received in response to
this Notice, and consider whether any such comments identify a need for
modification or revocation of the specific exemption.
