Aquashade, Nithiazine, d-limonene, and 2H-Cyclopent(d)isothiazol-
3(4H)-one, 5,6-dihydro-2-methyl- (MTI) Registration Review Interim
Decisions; Notice of Availability
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: This notice announces the availability of EPA's interim
registration review decisions for the pesticides aquashade, nithiazine,
d-limonene, and 2H-Cyclopent(d)isothiazol-3(4H)-one, 5,6-dihydro-2-
methyl- (MTI). Registration review is EPA's periodic review of
pesticide registrations to ensure that each pesticide continues to
satisfy the statutory standard for registration, that is, that the
pesticide can perform its intended function without causing
unreasonable adverse effects on human health or the environment.
Through this program, EPA is ensuring that each pesticide's
registration is based on current scientific and other knowledge,
including its effects on human health and the environment.

----------------------------------------------------------------------------------------------------------------
Aquashade (Interim Decision). Aquashade is as an aquatic herbicide
whose mode of action is light filtration. It is primarily used in small
water bodies like ornamental ponds and small lakes, fountains and other
landscaping water features, swimming holes, aquaculture ponds, and
animal watering holes. The Ecological Risk Assessment found no level of
concern risk exceedances to all taxa. The Human Health Risk Assessment
also indicated no risk (dietary, residential, and occupational).
Aquashade was not on either initial list of chemicals to be screened
under the Endocrine Disruptor Screening Program (EDSP), and an
endangered species assessment has not been conducted at this time. No
mitigation is proposed at this time. The Agency's final registration
review decision is dependent upon the assessment of risks to threatened
and endangered species and after an EDSP Federal Food, Drug and
Cosmetic Act (FFDCA) Section 408(p) determination has been made.
Nithiazine (Interim Decision). The Nithiazine Summary Document was
published on March 18, 2009. Nithiazine is used as part of a bait
station to control flies in animal housing facilities and other
industrial operations. The structure of the bait station makes contact
between nithiazine and humans unlikely; therefore, there are no human
health risk concerns for nithiazine. Since the active ingredient is
contained in a bait station, no ecological exposure is expected.
Therefore, there are no ecological risk concerns for nithiazine.
Nithiazine does not pose a threat to pollinators and the Agency has
determined that it will cause No Effect to listed species. The Agency
has determined that no additional data are required at this time to
support the continuing registrations of nithiazine products. The final
decision on the registration review for nithiazine will occur after an
EDSP FFDCA section 408(p) determination has been made.
d-Limonene (Interim Decision). The registration review docket for
d-limonene opened in September 2010. d-Limonene is a naturally
occurring chemical obtained from the rind of citrus fruits. It is
registered for use as an acaricide, insecticide, herbicide, insect
repellent, and is used as an inert ingredient for scent and flavoring
in other non-pesticide products. d-Limonene is currently registered for
use in/on food crops (citrus, pome fruits, grapes), feed crops, non-
food crops (ornamentals, Christmas trees, fencerows, recreational
areas, wood protection) and for residential uses. EPA published the
draft human health and ecological risk assessments in December 2014. A
qualitative human health assessment was conducted, and the Agency
concluded that d-limonene does not pose a risk to human health. A
quantitative ecological risk assessment was conducted and levels of
concern were exceeded for terrestrial plants and mammals (risks to
birds and terrestrial invertebrates could not be precluded). The Agency
is requiring modifications to several labels to reduce potential risks
of d-limonene to terrestrial birds and mammals. In addition, the Agency
will make several modifications to 40 CFR part 180. The Agency will
establish an exemption for the herbicidal uses of d-limonene from a
tolerance under subpart D, and existing exemption from tolerances from
the repellant uses of d-limonene under 180.539 subpart C will be moved
to subpart D for insecticidal uses. This Interim Decision does not
cover the EDSP component of this registration review case, nor does it
include a complete endangered species assessment or pollinator risk
assessment. The Agency's final registration review decision is
dependent upon the assessment of risks to threatened and endangered
species and pollinators as well as a determination under FFDCA Section
408(p) regarding endocrine disruption.
2H-Cyclopent(d)isothiazol- 3(4H)-one, 5,6-dihydro-2- methyl-
(Interim Decision). There is one EPA registered product containing
active ingredient 2H-Cyclopent(d)isothiazol-3(4H)-one, 5,6- dihydro-2-
methyl-, also known as MTI. MTI is a materials preservative for use in
the manufacture of aqueous compositions used in the manufacture of
imaging products. The Agency did not require any additional data in
support of MTI's registration review or need to conduct human health or
environmental risk assessments due to the lack of exposure concerns for
MTI's registered use. Based on the lack of potential exposure, the
Agency made a ``no effect'' determination for listed species under the
Endangered Species Act (ESA). Except for the EDSP component of the MTI
registration review case, the Agency is not requiring additional data
and is not proposing any risk reduction measures for this case. The
final decision on the registration review for MTI will occur after the
EDSP FFDCA section 408(p) determination is made.
Pursuant to 40 CFR 155.57, a registration review decision is the
Agency's determination whether a pesticide meets, or does not meet, the
standard for registration in the Federal Insecticide, Fungicide, and
Rodenticide Act (FIFRA). EPA has considered the pesticides found in the
Table in this unit in light of the FIFRA standard for registration. The
Interim Decision document in the dockets describes the Agency's
rationale for issuing a registration review interim decision for these
pesticides.
In addition to the interim registration review decision documents,
the registration review dockets for the pesticides listed in the Table
in this unit also includes other relevant documents related to the
registration review of these cases. The proposed interim registration
review decisions were posted to the docket and the public was invited
to submit any comments or new information.
EPA addresses the comments or information received during the 60-
day comment period in the discussion for each pesticide listed in this
document. During the 60-day comment period, no public comments were
received for aquashade, nithiazine, or 2H-Cyclopent(d)isothiazol-
3(4H)-one, 5,6-
[[Page 23296]]
dihydro-2- methyl (MTI). Comments were received for d-limonene however
the public comments received were not substantive and did not affect
the Agency's interim decision.
Pursuant to 40 CFR 155.58(c), the registration review case docket
for the pesticides listed in the Table in Unit II will remain open
until all actions required in the interim decisions have been
completed.
