The registration review final decisions for several of these cases are dependent on the assessment of listed species and designated critical habitats under the Endangered Species Act (ESA), determinations on the potential for endocrine disruption, and/or evaluation of risks to pollinators. 2-Propen-1-aminium, N, N-dimethylN-2-propenyl-, chloride, homopolymer (Interim Decision). The registration review docket for 2-propen-1-aminium, N, N-dimethyl-N-2-propenyl-, chloride, homopolymer opened in August 2015. The Agency did not receive any comments. There is one product containing this active ingredient; which is registered to control mollusks in potable water supplies. The Agency did not call-in any data in support of this registration review case. Additionally, the Agency did not conduct a human health or an environmental risk assessment since label instructions minimize exposure from the product’s registered use. Based on the lack of potential exposure, the Agency is making a ‘‘no effect’’ determination for listed species. The final decision on the registration review for this case will occur after an Endocrine Disruption Screen Program (EDSP) Federal Food Drug and Cosmetic Act (FFDCA) section 408(p) determination is made. Daminozide (Interim Decision). EPA is announcing the availability of the daminozide interim registration review decision. Daminozide is a plant growth regulator (PGR) used to control the development of commercially grown container plants. It is used in nurseries, shade houses, and greenhouses and is applied as a foliage spray that is systemically distributed throughout the VerDate Sep<11>2014 17:32 Jan 05, 2016 Jkt 238001 ................... ................... ................... ................... plant, a use pattern resulting in little or no potential for off-site drift. Daminozide has no registered food uses and no registered residential uses. EPA conducted both an ecological risk assessment and human health risk assessment for daminozide, and there were no human health risks of concern with registered daminozide uses. The Agency is not calling for mitigation for either ecological or human health risks from daminozide at this time. Except for ongoing ESA consultation, a pollinator risk assessment, and EDSP component of this registration review case, the Agency is proposing that no additional data and no further risk mitigation is needed for daminozide. The Agency’s final registration review decision is dependent upon the assessment of risks to threatened and endangered species, pollinators, and an EDSP determination. Dipropyl isocinchomeronate (Interim Decision). This notice announces the publication of the registration review interim decision for dipropyl isocinchomeronate. Dipropyl isocinchomeronate is registered for use as an insect repellent for use on humans and companion animals to repel flies, gnats, and other flying and biting insects. It is never the sole active ingredient; it is always co-formulated with other insecticides/repellents to broaden their spectrum of repellency. The Agency has concluded that there are no human health risk concerns associated with the use of dipropyl isocinchomeronate. Based on the limited usage, diffusion over a large treatment area, and the low probability of non-target organism exposure, the Agency has not found any ecological risks of concern associated with PO 00000 Frm 00024 Fmt 4703 Sfmt 4703 dipropyl isocinchomeronate and is making a ‘‘no effect’’ determination for all federally listed species and a ‘‘no habitat modification’’ determination for all designated critical habitat for listed species. The Agency concludes that no risk reduction measures or additional data are needed at this time. Dipropyl isocinchomeronate has not been evaluated under the EDSP. The Agency’s final registration review decision is dependent upon the result of the evaluation of potential endocrine effects. Fenoxaprop-p-ethyl (Interim Decision). Fenoxaprop-p-ethyl (FPE) is a selective aryloxy phenoxy-propionate herbicide registered for use on barley, cotton, rice, soybeans, and wheat for post-emergence control of grassy weeds. Additional non-agricultural use sites include conservation reserves, ornamentals, rights-of-way, and turf. In this interim registration review decision for fenoxaprop-p-ethyl, EPA has determined that no additional data are required at this time; however, certain risk reduction measures are necessary at this time. To address potential risk to non-target terrestrial monocots, spray drift management language is required for all fenoxaprop-p-ethyl product registrations used on agricultural, wide area, or rights-of-way use sites. The Agency also is requiring the implementation of label language clarifying use rates, to which the registrants have already agreed. In addition, EPA is requiring label language to include recommended herbicide-resistance management measures. The final registration review decision for fenoxaprop-p-ethyl is dependent upon an assessment of listed E:\FR\FM\06JAN1.SGM 06JAN1 mstockstill on DSK4VPTVN1PROD with NOTICES Federal Register / Vol. 81, No. 3 / Wednesday, January 6, 2016 / Notices species and designated critical habitats under the ESA, a determination of the potential for endocrine disruption, and a pollinator risk assessment. Imazapyr (Interim Decision). The registration review docket for imazapyr opened in June 2014. Imazapyr is a nonselective systemic herbicide registered for use as pre- and post-emergent treatments to control broad spectrum terrestrial and aquatic weeds including terrestrial annual and perennial grasses, broadleaf weeds, herbs, woody species, and riparian and emergent aquatic weed species. EPA published draft human health and ecological risk assessments at the time of the docket opening for a 60-day public comment period. In this imazapyr interim decision, the Agency has determined that no additional data are required and no changes to the affected registrations or their labeling are needed at this time. In this interim registration review decision, EPA is making no human health or environmental safety findings associated with the EDSP screening of imazapyr, nor is it making an endangered species finding. EPA’s registration review decision for imazapyr will depend upon the result of an EDSP FFDCA section 408(p) determination, complete pollinator determination, and ESA determination. Isoxaben (Interim Decision). Isoxaben is a pre-emergent benzamide herbicide registered for use to control broadleaf weeds. It is classified as a Group 21 herbicide that inhibits cell wall biosynthesis. It is registered for nonagricultural uses such as turf grass, ornamentals, and landscape mulch. It is also registered for agricultural use on bearing fruit and nut trees and vineyards. There are no human health risk concerns for isoxaben. However, there are potential ecological risks to aquatic and terrestrial plants and potential chronic risk to mammals. In this interim registration review decision for isoxaben, EPA has determined that no additional data are required at this time and that certain risk reduction measures are necessary, including uniform spray drift management and herbicide resistance management label language. The final registration review decision for isoxaben is dependent upon an assessment of listed species and designated critical habitats under the ESA, a determination of the potential for endocrine disruption, and a pollinator risk assessment. Paclobutrazol (Interim Decision). Paclobutrazol is a systemic PGR that slows vegetative growth by inhibiting cell elongation. Paclobutrazol is currently registered for use on turf grass (including in parks, athletic fields, golf VerDate Sep<11>2014 17:32 Jan 05, 2016 Jkt 238001 courses, and rights-of-ways), on ornamentals, as a tree injection, as a soil injection/basal tree drench, and as a seed treatment for various vegetables. There are no registered residential uses of paclobutrazol. EPA conducted a risk assessment for both human health and ecological risk. No human health risks were identified. The ecological risk assessment indicated potential risks to birds, reptiles, and terrestrial-phase amphibians, mammals, terrestrial and aquatic plants, and other aquatic organisms. In the paclobutrazol interim decision, the Agency has determined that certain additional data are required and certain changes to product labeling to address risk from runoff are needed at this time. EPA is making no human health or environmental safety findings associated with the EDSP screening of paclobutrazol, nor is it making an endangered species finding. EPA’s registration review decision for paclobutrazol will depend upon the result of an EDSP FFDCA section 408(p) determination, complete pollinator determination, and ESA determination. The silicates (silica gel and silicon dioxide) (Interim Decision). Silica gel and silicon dioxide are commonly referred to as the silicates, silica silicates or diatomaceous earth (DE) and are found in most soils. Silica gel and silicon dioxide are registered for use as insecticides on a variety of indoor and outdoor areas including crop and residential use sites to treat pests (including ants, boxelder bugs, cockroaches, crickets, slugs, flies, fleas, millipedes, silver-fish, sowbugs and ticks). EPA conducted an ecological risk assessment, including an endangered species assessment. EPA reached a ‘‘no effect’’ determination for all listed species, excluding 57 listed terrestrial invertebrate species, for which a ‘‘not likely to adversely affect’’ determination was made. EPA also concluded that there would be no modification of designated critical habitat. EPA engaged in informal consultation with the U.S. Fish and Wildlife Service (FWS) seeking concurrence on the ‘‘not likely to adversely affect’’ findings. FWS concurred with EPA’s ‘‘not likely to adversely affect’’ determination, thus completing consultation. No human health risk assessment was conducted for silica gel and silicon dioxide because no toxicological endpoints were identified to conduct a human health risk assessment. No risk mitigation measures for human health or ecological effects are included in the silica gel and silicon dioxide registration review interim decision. This interim decision does not include the EDSP component PO 00000 Frm 00025 Fmt 4703 Sfmt 4703 483 of this registration review case. The Agency’s final registration review decision will depend upon the result of an EDSP FFDCA section 408(p) determination. Sulfentrazone (Interim Decision). Sulfentrazone is a broad spectrum, preemergence, soil-directed proto porphyrinogen herbicide used to control a variety of weeds. It is registered for use on field crops, specialty vegetable crops, fruit trees, ornamentals, and turf grass. EPA completed quantitative human health and ecological risk assessments for sulfentrazone in 2014, and amended the ecological risk assessment in 2015. The Agency has risk concerns for pesticide handlers that can be adequately mitigated by requiring use of chemical-resistant gloves. In addition, there are potential risk concerns for terrestrial plants. In this interim registration review decision for sulfentrazone, EPA has determined that no additional data are required at this time and that certain risk reduction measures are necessary. These measures include uniform spray drift management language on sulfentrazone labels for products applied by spraying and herbicide resistance management language on all product labels. The Agency’s final registration review decision is dependent upon an assessment of listed species and designated critical habitats under the ESA, a determination of the potential for endocrine disruption, and a pollinator risk assessment. Tributyltin oxide (Interim Decision). There are four EPA registrations for tributyltin oxide for rubber coatings on the sonar domes of nuclear submarines and for oceanographic conductivity sensors. Based on the lack of potential for dietary exposure and no residential uses, the Agency did not conduct a human health risk assessment. Exposure to aquatic organisms would occur only from the small amount of tributyltin oxide potentially leaching from sonar domes, and the Agency believes that risks to non-target, non-listed species are minimal. Tributyltin oxide use as an antifoulant on sonar domes is undergoing ESA consultation with the Department of Defense, EPA, and the Services for compounds covered under EPA’s Uniform National Discharge Standards. No EDSP determination has been made at this time. Except for the EDSP component of the tributyltin oxide 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 tributyltin oxide will occur after the ESA consultation and the EDSP FFDCA E:\FR\FM\06JAN1.SGM 06JAN1 484 Federal Register / Vol. 81, No. 3 / Wednesday, January 6, 2016 / Notices section 408(p) determination have been 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 FIFRA. EPA has considered the pesticides listed in light of the FIFRA standard for registration. The interim decision documents in the docket describe the Agency’s rationale for issuing registration review interim decisions for these pesticides. In addition to the interim registration review decision document, the registration review docket for these pesticides 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 has addressed the substantive comments or information received during the 60-day comment period in the interim decision document for each pesticide listed in this document. Pursuant to 40 CFR 155.58(c), the registration review case docket for each pesticide discussed in this notice will remain open until all actions required in the interim decision have been completed. Background on the registration review program is provided at: https:// www2.epa.gov/pesticide-reevaluation.

Abstract: Ocean dumping—the transportation of any material for the purpose of dumping in ocean waters— cannot occur unless a permit is issued under the Marine Protection, Research, and Sanctuaries Act (MPRSA). EPA is responsible for issuing ocean dumping permits for all materials except dredged material. The U.S. Army Corps of Engineers (USACE) is responsible for issuing ocean dumping permits for dredged material using EPA’s environmental criteria. Ocean dumping permits for dredged material are subject to EPA review and concurrence. EPA is also responsible for designating and managing ocean sites for the disposal of wastes and other materials, and establishing Site Management and Monitoring Plans for ocean disposal sites. EPA collects or sponsors the collection of information for the purposes of permit issuance, reporting of emergency dumping to safety of life at sea, compliance with permit requirements, including specifically general permits for burial at sea and for transportation and disposal of vessels. EPA collects this information to ensure that ocean dumping is appropriately regulated and will not harm human health and the marine environment, based on applying the Ocean Dumping Criteria. The Ocean Dumping Criteria consider, among other things: The environmental impact of the dumping; the need for the dumping; the effect of the dumping on esthetic, recreational, or economic values; land- E:\FR\FM\06JAN1.SGM 06JAN1

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

    The registration review final decisions for several of these cases 
are dependent on the assessment of listed species and designated 
critical habitats under the Endangered Species Act (ESA), 
determinations on the potential for endocrine disruption, and/or 
evaluation of risks to pollinators.
    2-Propen-1-aminium, N, N-dimethyl-N-2-propenyl-, chloride, 
homopolymer (Interim Decision). The registration review docket for 2-
propen-1-aminium, N, N-dimethyl-N-2-propenyl-, chloride, homopolymer 
opened in August 2015. The Agency did not receive any comments. There 
is one product containing this active ingredient; which is registered 
to control mollusks in potable water supplies. The Agency did not call-
in any data in support of this registration review case. Additionally, 
the Agency did not conduct a human health or an environmental risk 
assessment since label instructions minimize exposure from the 
product's registered use. Based on the lack of potential exposure, the 
Agency is making a ``no effect'' determination for listed species. The 
final decision on the registration review for this case will occur 
after an Endocrine Disruption Screen Program (EDSP) Federal Food Drug 
and Cosmetic Act (FFDCA) section 408(p) determination is made.
    Daminozide (Interim Decision). EPA is announcing the availability 
of the daminozide interim registration review decision. Daminozide is a 
plant growth regulator (PGR) used to control the development of 
commercially grown container plants. It is used in nurseries, shade 
houses, and greenhouses and is applied as a foliage spray that is 
systemically distributed throughout the plant, a use pattern resulting 
in little or no potential for off-site drift. Daminozide has no 
registered food uses and no registered residential uses. EPA conducted 
both an ecological risk assessment and human health risk assessment for 
daminozide, and there were no human health risks of concern with 
registered daminozide uses. The Agency is not calling for mitigation 
for either ecological or human health risks from daminozide at this 
time. Except for ongoing ESA consultation, a pollinator risk 
assessment, and EDSP component of this registration review case, the 
Agency is proposing that no additional data and no further risk 
mitigation is needed for daminozide. The Agency's final registration 
review decision is dependent upon the assessment of risks to threatened 
and endangered species, pollinators, and an EDSP determination.
    Dipropyl isocinchomeronate (Interim Decision). This notice 
announces the publication of the registration review interim decision 
for dipropyl isocinchomeronate. Dipropyl isocinchomeronate is 
registered for use as an insect repellent for use on humans and 
companion animals to repel flies, gnats, and other flying and biting 
insects. It is never the sole active ingredient; it is always co-
formulated with other insecticides/repellents to broaden their spectrum 
of repellency. The Agency has concluded that there are no human health 
risk concerns associated with the use of dipropyl isocinchomeronate. 
Based on the limited usage, diffusion over a large treatment area, and 
the low probability of non-target organism exposure, the Agency has not 
found any ecological risks of concern associated with dipropyl 
isocinchomeronate and is making a ``no effect'' determination for all 
federally listed species and a ``no habitat modification'' 
determination for all designated critical habitat for listed species. 
The Agency concludes that no risk reduction measures or additional data 
are needed at this time. Dipropyl isocinchomeronate has not been 
evaluated under the EDSP. The Agency's final registration review 
decision is dependent upon the result of the evaluation of potential 
endocrine effects.
    Fenoxaprop-p-ethyl (Interim Decision). Fenoxaprop-p-ethyl (FPE) is 
a selective aryloxy phenoxy-propionate herbicide registered for use on 
barley, cotton, rice, soybeans, and wheat for post-emergence control of 
grassy weeds. Additional non-agricultural use sites include 
conservation reserves, ornamentals, rights-of-way, and turf. In this 
interim registration review decision for fenoxaprop-p-ethyl, EPA has 
determined that no additional data are required at this time; however, 
certain risk reduction measures are necessary at this time. To address 
potential risk to non-target terrestrial monocots, spray drift 
management language is required for all fenoxaprop-p-ethyl product 
registrations used on agricultural, wide area, or rights-of-way use 
sites. The Agency also is requiring the implementation of label 
language clarifying use rates, to which the registrants have already 
agreed. In addition, EPA is requiring label language to include 
recommended herbicide-resistance management measures. The final 
registration review decision for fenoxaprop-p-ethyl is dependent upon 
an assessment of listed

species and designated critical habitats under the ESA, a determination 
of the potential for endocrine disruption, and a pollinator risk 
assessment.
    Imazapyr (Interim Decision). The registration review docket for 
imazapyr opened in June 2014. Imazapyr is a non-selective systemic 
herbicide registered for use as pre- and post-emergent treatments to 
control broad spectrum terrestrial and aquatic weeds including 
terrestrial annual and perennial grasses, broadleaf weeds, herbs, woody 
species, and riparian and emergent aquatic weed species. EPA published 
draft human health and ecological risk assessments at the time of the 
docket opening for a 60-day public comment period. In this imazapyr 
interim decision, the Agency has determined that no additional data are 
required and no changes to the affected registrations or their labeling 
are needed at this time. In this interim registration review decision, 
EPA is making no human health or environmental safety findings 
associated with the EDSP screening of imazapyr, nor is it making an 
endangered species finding. EPA's registration review decision for 
imazapyr will depend upon the result of an EDSP FFDCA section 408(p) 
determination, complete pollinator determination, and ESA 
determination.
    Isoxaben (Interim Decision). Isoxaben is a pre-emergent benzamide 
herbicide registered for use to control broadleaf weeds. It is 
classified as a Group 21 herbicide that inhibits cell wall 
biosynthesis. It is registered for non-agricultural uses such as turf 
grass, ornamentals, and landscape mulch. It is also registered for 
agricultural use on bearing fruit and nut trees and vineyards. There 
are no human health risk concerns for isoxaben. However, there are 
potential ecological risks to aquatic and terrestrial plants and 
potential chronic risk to mammals. In this interim registration review 
decision for isoxaben, EPA has determined that no additional data are 
required at this time and that certain risk reduction measures are 
necessary, including uniform spray drift management and herbicide 
resistance management label language. The final registration review 
decision for isoxaben is dependent upon an assessment of listed species 
and designated critical habitats under the ESA, a determination of the 
potential for endocrine disruption, and a pollinator risk assessment.
    Paclobutrazol (Interim Decision). Paclobutrazol is a systemic PGR 
that slows vegetative growth by inhibiting cell elongation. 
Paclobutrazol is currently registered for use on turf grass (including 
in parks, athletic fields, golf courses, and rights-of-ways), on 
ornamentals, as a tree injection, as a soil injection/basal tree 
drench, and as a seed treatment for various vegetables. There are no 
registered residential uses of paclobutrazol. EPA conducted a risk 
assessment for both human health and ecological risk. No human health 
risks were identified. The ecological risk assessment indicated 
potential risks to birds, reptiles, and terrestrial-phase amphibians, 
mammals, terrestrial and aquatic plants, and other aquatic organisms. 
In the paclobutrazol interim decision, the Agency has determined that 
certain additional data are required and certain changes to product 
labeling to address risk from runoff are needed at this time. EPA is 
making no human health or environmental safety findings associated with 
the EDSP screening of paclobutrazol, nor is it making an endangered 
species finding. EPA's registration review decision for paclobutrazol 
will depend upon the result of an EDSP FFDCA section 408(p) 
determination, complete pollinator determination, and ESA 
determination.
    The silicates (silica gel and silicon dioxide) (Interim Decision). 
Silica gel and silicon dioxide are commonly referred to as the 
silicates, silica silicates or diatomaceous earth (DE) and are found in 
most soils. Silica gel and silicon dioxide are registered for use as 
insecticides on a variety of indoor and outdoor areas including crop 
and residential use sites to treat pests (including ants, boxelder 
bugs, cockroaches, crickets, slugs, flies, fleas, millipedes, silver-
fish, sowbugs and ticks). EPA conducted an ecological risk assessment, 
including an endangered species assessment. EPA reached a ``no effect'' 
determination for all listed species, excluding 57 listed terrestrial 
invertebrate species, for which a ``not likely to adversely affect'' 
determination was made. EPA also concluded that there would be no 
modification of designated critical habitat. EPA engaged in informal 
consultation with the U.S. Fish and Wildlife Service (FWS) seeking 
concurrence on the ``not likely to adversely affect'' findings. FWS 
concurred with EPA's ``not likely to adversely affect'' determination, 
thus completing consultation. No human health risk assessment was 
conducted for silica gel and silicon dioxide because no toxicological 
endpoints were identified to conduct a human health risk assessment. No 
risk mitigation measures for human health or ecological effects are 
included in the silica gel and silicon dioxide registration review 
interim decision. This interim decision does not include the EDSP 
component of this registration review case. The Agency's final 
registration review decision will depend upon the result of an EDSP 
FFDCA section 408(p) determination.
    Sulfentrazone (Interim Decision). Sulfentrazone is a broad 
spectrum, pre-emergence, soil-directed proto porphyrinogen herbicide 
used to control a variety of weeds. It is registered for use on field 
crops, specialty vegetable crops, fruit trees, ornamentals, and turf 
grass. EPA completed quantitative human health and ecological risk 
assessments for sulfentrazone in 2014, and amended the ecological risk 
assessment in 2015. The Agency has risk concerns for pesticide handlers 
that can be adequately mitigated by requiring use of chemical-resistant 
gloves. In addition, there are potential risk concerns for terrestrial 
plants. In this interim registration review decision for sulfentrazone, 
EPA has determined that no additional data are required at this time 
and that certain risk reduction measures are necessary. These measures 
include uniform spray drift management language on sulfentrazone labels 
for products applied by spraying and herbicide resistance management 
language on all product labels. The Agency's final registration review 
decision is dependent upon an assessment of listed species and 
designated critical habitats under the ESA, a determination of the 
potential for endocrine disruption, and a pollinator risk assessment.
    Tributyltin oxide (Interim Decision). There are four EPA 
registrations for tributyltin oxide for rubber coatings on the sonar 
domes of nuclear submarines and for oceanographic conductivity sensors. 
Based on the lack of potential for dietary exposure and no residential 
uses, the Agency did not conduct a human health risk assessment. 
Exposure to aquatic organisms would occur only from the small amount of 
tributyltin oxide potentially leaching from sonar domes, and the Agency 
believes that risks to non-target, non-listed species are minimal. 
Tributyltin oxide use as an antifoulant on sonar domes is undergoing 
ESA consultation with the Department of Defense, EPA, and the Services 
for compounds covered under EPA's Uniform National Discharge Standards. 
No EDSP determination has been made at this time. Except for the EDSP 
component of the tributyltin oxide 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 tributyltin oxide will occur after the ESA 
consultation and the EDSP FFDCA

[[Page 484]]

section 408(p) determination have been 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 FIFRA. EPA has considered the pesticides 
listed in light of the FIFRA standard for registration. The interim 
decision documents in the docket describe the Agency's rationale for 
issuing registration review interim decisions for these pesticides.
    In addition to the interim registration review decision document, 
the registration review docket for these pesticides 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 has addressed the substantive comments or information 
received during the 60-day comment period in the interim decision 
document for each pesticide listed in this document.
    Pursuant to 40 CFR 155.58(c), the registration review case docket 
for each pesticide discussed in this notice will remain open until all 
actions required in the interim decision have been completed.
