II. Background

A. What action is the Agency taking?

Pursuant to 40 CFR 155.58, this notice announces the availability of EPA's proposed and proposed interim registration review decisions for the pesticides shown in the following table, and opens a 60-day public comment period on the proposed and proposed interim decisions.

Ancymidol (Proposed Interim Decision)

The registration review docket for ancymidol (EPA-HQ-OPP-2011-0482) opened in June 2011. Ancymidol is a plant growth regulator registered for treating container-grown herbaceous plants, ornamental woody shrubs, and bedding plants grown in greenhouses and in outdoor plant-bedding areas. It is also registered for use as a seed treatment for ornamental plants, and treated seeds are used to start plants. Use of ancymidol is limited to nursery grown ornamentals. There are no food, feed, or residential uses registered for ancymidol. No pesticide tolerances have been established. EPA conducted a qualitative assessment for both human health and ecological risks. No risks of concern were identified in the human health risk assessment. The ecological risk assessment indicated that there was no reasonable expectation for any registered use of ancymidol to cause direct or indirect adverse effects to threatened and endangered species. A “no effect” determination was made for all federally listed species and designated critical habitat. Ancymidol has not been evaluated under the Endocrine Disruptor Screening Program (EDSP). Therefore, the Agency's final registration review decision is dependent upon the result of the evaluation of potential endocrine disruptor risk. Pending the outcome of this action, EPA is planning to issue an interim registration review decision for ancymidol.

DEET (Combined Work Plan and Proposed Interim Decision)

The registration review docket for DEET (N,N-diethyl-meta-toulamide) is opening (EPA-HQ-OPP-2012-0162) for public comment on a combined Work Plan and Proposed Interim Registration Review Decision. DEET is a broad-spectrum insect repellent registered for use against biting flies, biting midges, black flies, chiggers, deer flies, fleas, gnats, horse flies, mosquitoes, no-see-ums, sand flies, stable flies, and ticks. It is currently registered for non-food uses and residential uses. It can be directly used on clothing, applied to the skin, and used on horses. EPA conducted a qualitative assessment for both human health and environmental fate and ecological risks. No risks of concern were identified. The ecological risk assessment made a “no effect” determination for federally listed species and designated critical habitat. DEET has not been evaluated under the EDSP. Therefore, the Agency's final registration review decision is dependent upon the result of the evaluation of potential endocrine disruptor risk. Pending the outcome of this action, EPA is planning to issue an interim registration review decision for DEET.

Denatonium Saccharide (Proposed Interim Decision)

The registration review docket for denatonium saccharide (EPA-HQ-OPP-2008-0441) opened in June 2008. Denatonium saccharide is a bittering agent in squirrel, vole, dog, and cat repellents used on outdoor surfaces and structures such as trees, fences, poles, decks, planters, siding, garbage cans, furniture, seeds, and bulbs. EPA conducted a qualitative human health risk assessment and did not identify any risks of concern. The ecological risk assessment identified potential risks for birds and listed mammals. However, due to the number of conservative assumptions included in the assessment, the Agency is not proposing mitigation changes at this time. The risk assessment for denatonium saccharide did not come to a conclusion of “no effect” to listed species. Therefore, consultation with the U.S. Fish and Wildlife Service (USFWS) on the potential risk of denatonium saccharide to listed species will be necessary. Denatonium saccharide has not been evaluated under the EDSP. Therefore, the Agency's final registration review decision is dependent upon the result of Section 7 Endangered Species consultation with the USFWS and the evaluation of potential endocrine disruptor risk. Pending the outcome of these actions, EPA is planning to issue an interim registration review decision for denatonium saccharide.

Dioctyl Sodium Sulfosuccinate (Proposed Decision)

The registration review docket for DSS (EPA-HQ-OPP-2010-1006) opened in December 2010. DSS is registered as an insecticide and miticide in pet shampoos and spray products in combination with Undecylenic Acid (UDA). As a pesticidal active ingredient, there are no food uses and, thus, no tolerances are established. DSS is used as an active ingredient in over the counter stool-softener and laxative products for infants, children, and adults; it is also used in pharmaceutical, cosmetic, and food products. EPA has conducted a qualitative assessment for both human health and ecological risks, including listed species for DSS. The human health risk assessment did not Start Printed Page 32286identify any risks of concern for DSS. The ecological risk assessment made a “no effect” determination for federally listed species and designated critical habitat. Pursuant to FFDCA Section 408(p)(4), EPA has exempted DSS from the requirements of the EDSP in an Administrative Order entitled Exemption of Dioctyl Sodium Sulfosuccinate (DSS) and Undecylenic Acid (UDA) from the Requirements of the Endocrine Disruptor Screening Program which is available in the registration review docket.

Gas Cartridges; Inorganic Nitrate—Nitrite, Carbon and Carbon Dioxide, and Sulfur (Proposed Interim Decision)

Potassium and sodium nitrate, carbon and carbon dioxide, and sulfur are ingredients in fumigant gas cartridge products, which are available in small and large sizes. Both sizes are registered to control burrowing mammals, but only the large gas cartridge is registered to also control coyotes, red foxes and skunks. Gas cartridges are registered for outdoor use only. To use the products, the user lights the fuse, places the cartridge in the burrow or den and seals the entrance. Animals within the burrow or den are asphyxiated by the release of carbon dioxide and toxic gases.

The Agency relied on a previous human health risk assessment in making its registration review decisions and determined that no human health risks of concern exist for these compounds. The Agency conducted a new ecological risk assessment for the gas cartridges for registration review. The risk assessment did find the potential for adverse effects to a number of endangered species from gas cartridge use. EPA developed mitigation to address the risk to a number of the endangered species. In most cases, the mitigation involves the use of Endangered Species Protection Bulletins. Because the gas cartridges contain the three compounds, these Bulletins are available for comment in the Inorganic Nitrate—Nitrite, Carbon and Carbon Dioxide, and Sulfur Registration Review dockets (EPA-HQ-OPP-2007-1118, EPA-HQ-OPP-2007-0705, and EPA-HQ-OPP-2008-0176, respectively). Although implementation of these Bulletins will address risk to some endangered species from gas cartridge use, risk to a number of other endangered species remains. Additionally, potassium and sodium nitrate, carbon and carbon dioxide, and sulfur have not been evaluated under the EDSP. Therefore, the Agency's final registration review decisions are dependent upon the result of Section 7 Endangered Species consultation with the USFWS and the evaluation of potential endocrine disruptor risk. Pending the outcome of these actions, EPA is planning to issue interim registration review decisions for sodium and potassium nitrate, carbon and carbon dioxide, and sulfur.

Metofluthrin (Proposed Interim Decision)

The registration review docket for metofluthrin (EPA-HQ-OPP-2012-0105) opened in June 2013. Metofluthrin is a Type 1 synthetic pyrethroid insect repellent and insecticide with products registered for use in residential and commercial areas, including barns, patios, porches, campgrounds, stables and kennels to repel adult mosquitoes and kill bed bugs. The products registered for outdoor use are an impregnated paper repellent strip, a battery-operated personal outdoor insect repellent fan, an impregnated fiberglass ring heated by a candle, and battery-operated automated mister. The registered indoor use is a soluble concentrate used as a spray to kill bedbugs. There are no registered food/feed uses for metofluthrin. No pesticide tolerances have been established. EPA conducted a human health risk assessment and an ecological risk assessment. No risks of concern were identified in the human health risk assessment. The ecological risk assessment indicated that there was no reasonable expectation for any registered use of metofluthrin to cause direct or indirect adverse effects to threatened and endangered species. A “no effect” determination was made for all federally listed species and designated critical habitat. Metofluthrin has not been evaluated under the EDSP. Therefore, the Agency's final registration review decision is dependent upon the result of the evaluation of potential endocrine disruptor risk. Pending the outcome of this action, EPA is planning to issue an interim registration review decision for metofluthrin.

Polybutene Resins (Proposed Decision)

The registration review docket for polybutene resins (EPA-HQ-OPP-2009-0649) opened in June 2010. Polybutene is a sticky polymer registered for use as a bird and small mammal repellent. It is used to prevent house sparrows, pigeons, and starlings from roosting inside and outside of buildings, as well as to prevent beavers from attacking trees and shrubs. There are no food/feed uses and, it is exempt from a tolerance requirement when used as a sticker agent in packaging of insect control products used on food crops. Polybutene is approved by the U.S. Food and Drug Administration (FDA) as an indirect food additive and is used as an ingredient in cosmetic products that are applied directly to the skin such as sun block or moisturizer, and that may be incidentally ingested, such as lipstick. EPA conducted a qualitative assessment for both human health and environmental fate and ecological risks. No risks of concern were identified in the human health risk assessment. The ecological risk assessment indicated that there was no reasonable expectation for any registered use of polybutene to cause direct or indirect adverse effects to threatened and endangered species. A “no effect” determination was made for all federally listed species and designated critical habitat. Pursuant to FFDCA Section 408(p)(4), EPA has exempted polybutene from the requirements of the EDSP in an Administrative Order (AO) entitled Exemption of Polybutene from the Requirements of the Endocrine Disruptor Screening Program. The AO is available in the registration review docket.

Sulfur (Proposed Interim Decision)

The registration review docket for sulfur (EPA-HQ-OPP-2008-0176) opened in March 2008. Sulfur is used as an insecticide and fungicide on a wide range of field and greenhouse-grown food and feed crops, livestock, livestock quarters, and indoor and outdoor residential sites. Sulfur is also registered for use in gas cartridge products, along with inorganic nitrate/nitrite, carbon, and carbon dioxide. EPA has conducted a qualitative assessment for both human health and ecological risks, including listed species for sulfur. Details of the assessment for the gas cartridge use are summarized under the gas cartridge heading in this unit. For uses of sulfur other than gas cartridges, the Agency is making a “no effect” determination for all listed aquatic species, and a “no effect” determination for direct effects to listed terrestrial vertebrates that do not rely on insects as a primary food source. However, at this time, the Agency is not able to make an endangered species determination on terrestrial invertebrates, terrestrial plants, or indirect effects to terrestrial vertebrates with insects as a primary food source. Sulfur has not been evaluated under the EDSP. Therefore, the Agency's final registration review decision is dependent upon the result of Section 7 Endangered Species consultation with the USFWS and the evaluation of potential endocrine disruptor risk. Pending the outcome of these actions, EPA is planning to issue Start Printed Page 32287an interim registration review decision for sulfur.

Undecylenic Acid (Proposed Decision)

The registration review docket for UDA (EPA-HQ-OPP-2011-0910) opened in December 2011. UDA is registered as an insecticide and miticide in pet shampoos and spray products in combination with dioctyl sodium sulfosuccinate (DSS). As a pesticidal active ingredient, there are no food uses and, thus, no tolerances are established. UDA is approved by the FDA as an active ingredient in over the counter anti-fungal products, and it is also used as a flavoring agent. EPA has conducted a qualitative assessment for both human health and ecological risks, including listed species for UDA. The human health risk assessment did not identify any risks of concern for UDA. The ecological risk assessment made a “no effect” determination for federally listed species and designated critical habitat. Pursuant to FFDCA Section 408(p)(4), EPA has exempted UDA from the requirements of the EDSP in an AO entitled Exemption of Dioctyl Sodium Sulfosuccinate (DSS) and Undecylenic Acid (UDA) from the Requirements of the Endocrine Disruptor Screening Program which is available in the registration review docket.

This notice also announces the registration review case closure for the pesticide amitrole (case 0095) and the availability of the amitrole case closure document. The Notice of Receipt of a Request to Voluntarily Cancel Certain Pesticide Registrations was issued in the Federal Register of August 28, 2013 (78 FR 53141)(FRL-9396-4), and no substantive public comments were received during the 180-day comment period that impacted the Agency's decision to grant the cancellation request. In the Federal Register of April 11, 2014 (79 FR 20199) (FRL-9908-31), the Agency published the Cancellation Order for all amitrole product registrations. Due to the cancellation of all registered amitrole products in the United States, the Agency closed the registration review case for amitrole, pursuant to 40 CFR 155.42(c). In addition to the registration review case closure document, the registration review docket (EPA-HQ-OPP-2011-0105) for amitrole, also includes other relevant documents related to the registration review of this case. This action is not open for public comment.

The registration review docket for a pesticide includes earlier documents related to the registration review of the case. For example, the review opened with a Summary Document, containing a Preliminary Work Plan, for public comment. A Final Work Plan was placed in the docket following public comment on the initial docket.

The documents in the dockets describe EPA's rationales for conducting additional risk assessments for the registration review of the pesticides included in the table in Unit II.A., as well as the Agency's subsequent risk findings and consideration of possible risk mitigation measures. These proposed and proposed interim registration review decisions are supported by the rationales included in those documents.

Following public comment, the Agency will issue final registration review decisions or interim registration review decisions for products containing the pesticides listed in the table in Unit II.A.

The registration review program is being conducted under congressionally mandated time frames, and EPA recognizes the need both to make timely decisions and to involve the public. Section 3(g) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) required EPA to establish by regulation procedures for reviewing pesticide Start Printed Page 32288registrations, originally with a goal of reviewing each pesticide's registration every 15 years to ensure that a pesticide continues to meet the FIFRA standard for registration. The Agency's final rule to implement this program was issued in August 2006 and became effective in October 2006, and appears at 40 CFR part 155, subpart C. The Pesticide Registration Improvement Act of 2003 (PRIA) was amended and extended in September 2007. FIFRA, as amended by PRIA in 2007, requires EPA to complete registration review decisions by October 1, 2022, for all pesticides registered as of October 1, 2007.

The registration review final rule at 40 CFR 155.58(a) provides for a minimum 60-day public comment period on all proposed registration review decisions. This comment period is intended to provide an opportunity for public input and a mechanism for initiating any necessary amendments to the proposed decision. All comments should be submitted using the methods in ADDRESSES, and must be received by EPA on or before the closing date. These comments will become part of the docket for the pesticides included in the table in Unit II.A. Comments received after the close of the comment period will be marked “late.” EPA is not required to consider these late comments.

The Agency will carefully consider all comments received by the closing date and will provide a “Response to Comments Memorandum” in the docket. The final registration review decision will explain the effect that any comments had on the decision and provide the Agency's response to significant comments.

Background on the registration review program is provided at: http://www.epa.gov/​oppsrrd1/​registration_​review. Links to earlier documents related to the registration review of these pesticides are provided at: http://www.epa.gov/​oppsrrd1/​registration_​review/​reg_​review_​status.htm.

B. What is the Agency's authority for taking this action?

Section 3(g) of FIFRA and 40 CFR part 155, subpart C, provide authority for this action.
