Environmental Protection Agency (EPA).
This notice announces the availability of EPA's draft human health and ecological risk assessments for the registration review of ancymidol, fosthiazate, lactofen, polybutene resins, quizalofop, and soap salts and opens a public comment period on these documents. 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, the pesticide can perform its intended function without unreasonable adverse effects on human health or the environment. As part of the registration review process, the Agency has completed draft risk assessments for each of the subject chemicals and is making them available for public comment. After reviewing comments received during the public comment period, EPA will issue a revised risk assessment, if appropriate, explain any changes to the draft risk assessment, and respond to comments and may request public input on risk mitigation. Through Start Printed Page 17202this 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.

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 and/or environmental effects from exposure to the pesticides discussed in this document, compared to the general population.
EPA is conducting its registration review of the pesticides identified in this document pursuant to section 3(g) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Procedural Regulations for Registration Review at 40 CFR part 155, subpart C. Section 3(g) of FIFRA provides, among other things, that the registrations of pesticides are to be reviewed every 15 years. Under FIFRA, a pesticide product may be registered or remain registered only if it meets the statutory standard for registration given in FIFRA section 3(c)(5). When used in accordance with widespread and commonly recognized practice, the pesticide product must perform its intended function without unreasonable adverse effects on the environment; that is, without any unreasonable risk to man or the environment, or a human dietary risk from residues that result from the use of a pesticide in or on food.
III. Registration Reviews
A. What action is the Agency taking?
As directed by FIFRA section 3(g), EPA is reviewing the pesticide registrations for ancymidol, fosthiazate, lactofen, polybutene resins, quizalofop, and soap salts to ensure that they continue to satisfy the FIFRA standard for registration—that is, that these pesticides can still be used without unreasonable adverse effects on human health or the environment.
At this stage in the registration review process, consistent with the proposed notice, published in the Federal Register issue of August 17, 2012 (77 FR 49792) (FRL-9356-5), jointly developed with the U.S. Department of Agriculture, the National Marine Fisheries Service, and the U.S. Fish and Wildlife Service (“the Services”) to enhance opportunities for stakeholder input during pesticide registration reviews and endangered species consultations, draft environmental risk assessments include a screening-level evaluation of the potential risks to federally listed endangered and threatened species (hereafter referred to as “listed species”). EPA intends to complete a refined assessment of potential risks to individual listed Start Printed Page 17203species, as needed. The refined listed species assessments will be based on the recommendations of the National Research Council (NRC), which has been tasked with providing advice on ecological risk assessment tools and scientific approaches in developing listed species risk assessments that are compliant with both FIFRA and the Endangered Species Act (ESA). EPA anticipates that the NRC report, expected in Spring 2013, will provide recommendations to ensure scientific soundness and maximize the utility of risk assessment refinements for listed species. Additional information can be found at the following Web site: http://www8.nationalacademies.org/cp/projectview.aspx?key=49396. Useful refinements to the listed species assessments are expected to include, but not be limited to, the following:
- More detailed, species-specific ecological and biological data.
- More detailed and accurate information on chemical use patterns.
- Sub-county level spatial proximity data depicting the co-occurrence of potential effects areas and listed species and any designated critical habitat.
In the event that a draft risk assessment shows risks of concern to human health or the environment for a specific chemical, EPA reserves the right to initiate mitigation at this stage of registration review. This effort to mitigate a chemical's risks early in the registration review process is consistent with the Agency's approach for registration review. Where risks are identified early in the registration review process and opportunities for early mitigation exist, the Agency may pursue those opportunities as they arise, rather then waiting for completion of a chemical's registration review in order to mitigate risks. The public comment period for the draft risk assessments allows members of the public to provide comments and suggestions for revising the draft risk assessments and for reducing risks.
Pursuant to 40 CFR 155.53(c), EPA is providing an opportunity, through this notice of availability, for interested parties to provide comments and input concerning the Agency's draft human health and ecological risk assessments for ancymidol, fosthiazate, lactofen, polybutene resins, quizalofop, and soap salts. Such comments and input could address, among other things, the Agency's risk assessment methodologies and assumptions, as applied in these draft risk assessments.
The Agency will consider all comments received during the public comment period and make changes, as appropriate, to the draft human health and ecological risk assessments. EPA will then issue revised risk assessments, if appropriate, and explain any changes to the draft risk assessments, and respond to comments. In the Federal Register notice announcing the availability of the revised risk assessments, if any of the revised risk assessments indicate risks of concern, the Agency may provide a comment period for the public to submit suggestions for mitigating the risks identified in those revised risk assessments. At present, EPA is releasing registration review draft risk assessments for the pesticide cases identified in the following table and further described in this unit.

- Ancymidol. The registration review docket for ancymidol (EPA-HQ-OPP-2011-0482) opened in the Federal Register issue of June 29, 2011 (76 FR 38166) (FRL-8877-4). Ancymidol is a plant growth regulator that acts by inhibiting giberillin biosynthesis, resulting in plants with more compact growth. Ancymidol is registered for use only on container grown greenhouse and nursery ornamentals. It is used only on plants grown for commercial production and has no food, feed, or residential uses. The Final Work Plan for ancymidol described numerous data requirements for registration review, and a registration review timeline that included the issuance of a data call-in. However, EPA has revisited the timeline and data requirements for registration review and determined that a data call-in is not necessary for ancymidol. The Agency has conducted qualitative environmental and human health risk assessments for ancymidol based on the available information and on limited use of this pesticide active ingredient.
- Fosthiazate. The registration review docket for fosthiazate (EPA-HQ-OPP-2009-0267) opened in the Federal Register issue of June 24, 2009 (74 FR 30077) (FRL-8422-4). Fosthiazate is an organophosphate nematicide and insecticide that is currently registered for use on tomatoes. The Agency has conducted a human health risk assessment for both dietary (food and drinking water) and occupational exposure pathways. The Agency has also conducted a quantitative ecological risk assessment, which includes a screening-level listed species assessment. EPA acknowledges that further refinements to the listed species assessment will be completed in future revisions and requests public comment on specific areas that will reduce the uncertainties associated with the characterization of risk to listed species identified in the current assessment.
- Lactofen. The registration review docket for lactofen (EPA-HQ-OPP-2005-0287) opened in the Federal Register issue of February 2, 2007 (72 FR 5050) (FRL-8113-1). Lactofen is a light dependent peroxidizing herbicide (LDPH), and is registered for use on conifer seedlings, cotton, kenaf, peanuts, and soybean, with local registrations on fruiting vegetables, okra, snap beans, and strawberries. For lactofen, the Agency has conducted an occupational handler exposure risk assessment for the application of lactofen on conifer seedlings, snap beans, soybeans, and strawberries. The Agency has also conducted an ecological risk assessment, which includes a screening-level listed species assessment. EPA acknowledges that further refinements to the listed species assessment will be completed in future revisions and requests public comment Start Printed Page 17204on specific areas that will reduce the uncertainties associated with the characterization of risk to listed species identified in the current assessment.
- Polybutene resins. The registration review docket for polybutene resins (EPA-HQ-OPP-2009-0649) opened in the Federal Register issue of June 23, 2010 (75 FR 35810) (FRL-8832-3). 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 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 has conducted a qualitative assessment for both human health and environmental fate and ecological risks.
Quizalofop. The registration review docket for quizalofop ethyl and quizalofop-p-ethyl (EPA-HQ-OPP-2007-1089) opened in the Federal Register issue of December 19, 2007 (72 FR 71893) (FRL-8342-9). Quizalofop ethyl is a 50/50 racemic mixture of R-and S-enantiomers; quizalofop-p-ethyl is the purified R-enantiomer which is pesticidally active. Quizalofop-p-ethyl is registered for use to control weeds in food crops (including barley, beans, lentil, peas, sorghum, soybean, and sugar beets), non-food crops grown for seed (including alfalfa, carrots, garlic, onion, radish, and spinach), and non-cropland (including rights-of-way and fencerows). Quizalofop-p-ethyl is not registered for residential use. The Agency has conducted a human health assessment for both dietary (food and drinking water) and occupational exposure pathways. The Agency has conducted a quantitative ecological risk assessment, including a listed species assessment, for quizalofop. EPA acknowledges that further refinements to the listed species assessment may be completed in future revisions and requests public comment on specific areas that will reduce the uncertainties associated with the characterization of risk to listed species identified in the current assessment.
- Soap salts. The registration review docket for soap salts (EPA-HQ-OPP-2008-0519) opened in the Federal Register issue of September 15, 2008 (73 FR 53244) (FRL-8381-3). The case consists of three active ingredients, the ammonium, potassium, and sodium salts of fatty acids, which are registered for use as acaricides, algaecides, herbicides, and insecticides on food and non-food crops in various settings, chiefly residential and agricultural. Ammonium and sodium soap salts are also used as animal repellents. Because the Agency has not identified any toxicological endpoints for human health risk assessment and because current product labels are adequate to protect for potential eye and skin irritation, a qualitative human health risk assessment was conducted for soap salts. The Agency has conducted a quantitative ecological risk assessment, which includes a screening-level listed species assessment. EPA acknowledges that further refinements to the listed species assessment will be completed in future revisions and requests public comment on specific areas that will reduce the uncertainties associated with the characterization of risk to listed species identified in the current assessment.
