EPA is making available the Agency’s revised risk assessments, a response to comments, and related documents for carbofuran. The Agency’s environmental fate and effects risk assessment was initially issued for comment through a Federal Register notice published on June 24, 2005 (70 FR 36586) (FRL–7719–2) and the human health risk assessment was initially issued for comment through a Federal Register notice published on September 14, 2005 (70 FR 54377) (FRL–7731–4). EPA also is soliciting public comment on risk reduction options for carbofuran and an initial alternatives analysis. EPA developed the risk assessments for carbofuran as part of its public process for making pesticide reregistration eligibility and tolerance reassessment decisions. Through these programs, EPA is ensuring that pesticides meet current standards under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA). Carbofuran works as a cholinesterase inhibitor and is used to treat pests of food and non-food crops as either a flowable or granular formulation. It is registered for food uses, which include alfalfa, artichoke, banana, barley, coffee, corn (field, pop, and sweet), cotton seed, cucurbits (cucumber, melons, and squash), grapes, oats, pepper, plantain, VerDate Aug<31>2005 14:47 Mar 21, 2006 Jkt 208001 potato, sorghum, soybean, spinach, sugar beet, sugarcane, sunflower, and wheat. Carbofuran is also registered for non-food uses, which include agricultural fallow land, cotton, ornamental and/or shade trees, ornamental herbaceous plants, ornamental non-flowering plants, ornamental woody shrubs and vines, pine, and tobacco. Carbofuran is applied by aircraft or ground equipment by methods that include broadcast, banded, in furrow, and drip irrigation. EPA is providing an opportunity, through this notice, for interested parties to provide risk management proposals or otherwise comment on risk management for carbofuran. Risks of concern associated with the use of carbofuran are: human dietary and occupational risks, and ecological risks to birds and mammals. In targeting these risks of concern, the Agency solicits information on effective and practical risk reduction measures. EPA is applying the principles of public participation to all pesticides undergoing reregistration and tolerance reassessment. The Agency’s Pesticide Tolerance Reassessment and Reregistration; Public Participation Process, published in the Federal Register on May 14, 2004, (69 FR 26819)(FRL–7357–9) explains that in conducting these programs, EPA is tailoring its public participation process to be commensurate with the level of risk, extent of use, complexity of issues, and degree of public concern associated with each pesticide. Due to its uses, risks, and other factors, carbofuran is being reviewed through the full 6-Phase public participation process. All comments should be submitted using the methods in ADDRESSES, and must be received by EPA on or before the closing date. Comments and proposals will become part of the Agency Docket for carbofuran. Comments received after the close of the comment period will be marked ‘‘late.’’ EPA is not required to consider these late comments. After considering comments received, EPA will develop and issue for comment the carbofuran IRED. The decisions presented in this IRED may be supplemented by further risk mitigation measures when EPA considers its cumulative assessment of the N-methyl carbamate pesticides. B. What is the Agency’s Authority for Taking this Action? Section 4(g)(2) of FIFRA as amended directs that, after submission of all data concerning a pesticide active ingredient, ‘‘the Administrator shall determine whether pesticides containing such PO 00000 Frm 00022 Fmt 4703 Sfmt 4703 active ingredient are eligible for reregistration,’’ before calling in product specific data on individual end-use products and either reregistering products or taking other ‘‘appropriate regulatory action.’’ Section 408(q) of the FFDCA, 21 U.S.C. 346a(q), requires EPA to review tolerances and exemptions for pesticide residues in effect as of August 2, 1996, to determine whether the tolerance or exemption meets the requirements of section 408(b)(2) or (c)(2) of FFDCA. This review is to be completed by August 3, 2006. List of Subjects Environmental protection, Pesticides and pests. Dated: March 9, 2006.

Make sure to submit your comments by the comment period deadline identified. II. Background cprice-sewell on PROD1PC70 with NOTICES A. What Action is the Agency Taking? Under section 4 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), EPA is reevaluating existing pesticides to ensure that they meet current scientific and regulatory standards. EPA has completed a Reregistration Eligibility Decision (RED) for the pesticides PHMB, 4-t, BIT and Aza under section 4(g)(2)(A) of FIFRA. PHMB is used as a fungicide, algicide, and sanitizer in swimming pools; preservative for cut flowers; materials preservative; bacteriostat in industrial processes and water systems; and hard surface disinfectant (food and non-food contact surfaces). End-use products are formulated as soluble concentrates, as solids, as ready-to-use solutions, and in water-soluble packaging. 4-t is used in disinfectants, hard nonporous surface sanitizers and air deodorizing products used in agricultural premises, in food handling establishments, commercial, institutional and industrial premises, residential, public access premises and in medical settings. These products primarily are used on hard, non-porous surfaces (walls, floors, tables, fixtures) textiles (clothing, diapers, mattresses and bedding), carpets, medical instruments and agricultural equipment. BIT is an antimicrobial that is used as an industrial preservative for the protection of water-based adhesives, caulks, sealants, grouts, spackling, ready-mixed cements, ready-mixed wallboard compounds, aqueous compositions such as emulsion paints, aqueous slurries, home cleaning and car care products, laundry detergents, fabric softeners, stain removers, inks, photographic processing solutions, paints and stains, titanium dioxide slurries, oil in water emulsions, latices, metalworking fluids, casein/rosin dispersions, textile spin-finish solutions, pesticide formulations, tape joint compound, leather processing solutions, preservation of fresh animal hides and skins, and for offshore and terrestrial gas/oil drilling muds and packer fluids preservation. BIT is also used as an inert ingredient in a variety VerDate Aug<31>2005 14:47 Mar 21, 2006 Jkt 208001 of products as a materials preservative. Exposures and risks from the use of products containing BIT as both the active and inert ingredients are assessed in this RED. End-use products are formulated as either a soluble, ready-touse, or flowable concentrates (all of which are considered to be liquids). Aza consists of an equilibrium mixture of three chemicals (I: 5hydroxymethoxymethyl-1-aza-3,7dioxabicyclo(3,3,0)octane; II: 5hydroxymethyl-1-aza-3,7dioxabicyclo(3,3,0)octane; III: 5hydroxypoly(methylene-oxy)methyl-1aza-3,7-dioxabicyclo(3,3,0)octane). These chemicals cannot be divided into components for individual testing and the three of them will be referred to as azadioxabicyclooctane in the Reregistration Eligibilty Decision. This mixture is registered as a preservative for antimicrobial control in the following use sites: Oil recovery drilling muds and flooding fluids; industrial adhesives and coatings (natural based and synthetic); latex and polymer emulsions; metalworking cutting fluids; latex paints; paper coatings; caulks and sealants; inks; pigment dispersion and pigment slurry; and textile fiber finishes that are not intended as clothing. Azadioxabicyclooctane has been cleared by the Food and Drug Administration (FDA) for use as an antibacterial preservative in paper and paperboard products that are limited to dry food contact only in 21 CFR 176.180 as well as a component in paper adhesives in 21 CFR 175.105. EPA has determined that the data base to support reregistration is substantially complete and that products containing PHMB, 4-t, BIT and Aza are eligible for reregistration provided the risks are mitigated either in the manner described in the RED or by another means that achieves equivalent risk reduction. Upon submission of any required product specific data under section 4(g)(2)(B) and any necessary changes to the registration and labeling (either to address concerns identified in the RED or as a result of product specific data), EPA will make a final reregistration decision under section 4(g)(2)(C) for products containing PHMB, 4-t, BIT and Aza. Although, the RED decisions were made in FY 04 (PHMB) and FY05 (4-t, BIT and Aza), certain components of the documents, which did not affect the final regulatory decisions, were undergoing final editing at that time. None of these additions or changes alter the conclusions documented in the PHMB, 4-t, BIT and Aza REDs now available for comment. PO 00000 Frm 00024 Fmt 4703 Sfmt 4703 EPA is applying the principles of public participation to all pesticides undergoing reregistration and tolerance reassessment. The Agency’s Pesticide Tolerance Reassessment and Reregistration; Public Participation Process, published in the Federal Register on May 14, 2004, (69 FR 26819)(FRL–7357–9) explains that in conducting these programs, EPA is tailoring its public participation process to be commensurate with the level of risk, extent of use, complexity of issues, and degree of public concern associated with each pesticide. Due to its uses, risks, and other factors, PHMB, 4-t, BIT and Aza were reviewed through the modified 4-Phase process. Through this process, EPA worked extensively with stakeholders and the public to reach the regulatory decisions for PHMB, 4-t, BIT and Aza. The reregistration program is being conducted under Congressionally mandated time frames, and EPA recognizes the need both to make timely decisions and to involve the public. The Agency is issuing the PHMB, 4-t, BIT and Aza REDs for public comment. This comment period is intended to provide an additional opportunity for public input and a mechanism for initiating any necessary amendments to the RED. 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 Agency Dockets for PHMB, 4-t, BIT and Aza. 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 and regulations.gov. If any comment significantly affects the document, EPA also will publish an amendment to the RED in the Federal Register. In the absence of substantive comments requiring changes, the PHMB, 4-t, BIT and Aza REDs will be implemented as they are now presented. B. What is the Agency’s Authority for Taking this Action? Section 4(g)(2) of FIFRA as amended directs that, after submission of all data concerning a pesticide active ingredient, ‘‘the Administrator shall determine whether pesticides containing such active ingredient are eligible for reregistration,’’ before calling in product specific data on individual end-use products and either reregistering products or taking other ‘‘appropriate regulatory action.’’ E:\FR\FM\22MRN1.SGM 22MRN1 Federal Register / Vol. 71, No. 55 / Wednesday, March 22, 2006 / Notices List of Subjects Environmental protection, pesticides and pests.

suggest alternatives.
    vii. Explain your views as clearly as possible, avoiding the use of 
profanity or personal threats.
    viii. Make sure to submit your comments by the comment period 
deadline identified.

II. Background

A. What Action is the Agency Taking?

     Under section 4 of the Federal Insecticide, Fungicide, and 
Rodenticide Act (FIFRA), EPA is reevaluating existing pesticides to 
ensure that they meet current scientific and regulatory standards. EPA 
has completed a Reregistration Eligibility Decision (RED) for the 
pesticides PHMB, 4-t, BIT and Aza under section 4(g)(2)(A) of FIFRA.
     PHMB is used as a fungicide, algicide, and sanitizer in swimming 
pools; preservative for cut flowers; materials preservative; 
bacteriostat in industrial processes and water systems; and hard 
surface disinfectant (food and non-food contact surfaces). End-use 
products are formulated as soluble concentrates, as solids, as ready-
to-use solutions, and in water-soluble packaging.
     4-t is used in disinfectants, hard non-porous surface sanitizers 
and air deodorizing products used in agricultural premises, in food 
handling establishments, commercial, institutional and industrial 
premises, residential, public access premises and in medical settings. 
These products primarily are used on hard, non-porous surfaces (walls, 
floors, tables, fixtures) textiles (clothing, diapers, mattresses and 
bedding), carpets, medical instruments and agricultural equipment.
     BIT is an antimicrobial that is used as an industrial preservative 
for the protection of water-based adhesives, caulks, sealants, grouts, 
spackling, ready-mixed cements, ready-mixed wallboard compounds, 
aqueous compositions such as emulsion paints, aqueous slurries, home 
cleaning and car care products, laundry detergents, fabric softeners, 
stain removers, inks, photographic processing solutions, paints and 
stains, titanium dioxide slurries, oil in water emulsions, latices, 
metalworking fluids, casein/rosin dispersions, textile spin-finish 
solutions, pesticide formulations, tape joint compound, leather 
processing solutions, preservation of fresh animal hides and skins, and 
for offshore and terrestrial gas/oil drilling muds and packer fluids 
preservation. BIT is also used as an inert ingredient in a variety of 
products as a materials preservative. Exposures and risks from the use 
of products containing BIT as both the active and inert ingredients are 
assessed in this RED. End-use products are formulated as either a 
soluble, ready-to-use, or flowable concentrates (all of which are 
considered to be liquids). Aza consists of an equilibrium mixture of 
three chemicals (I: 5-hydroxymethoxymethyl-1-aza-3,7-
dioxabicyclo(3,3,0)octane; II: 5-hydroxymethyl-1-aza-3,7-
dioxabicyclo(3,3,0)octane; III: 5-hydroxypoly(methylene-oxy)methyl-1-
aza-3,7-dioxabicyclo(3,3,0)octane). These chemicals cannot be divided 
into components for individual testing and the three of them will be 
referred to as azadioxabicyclooctane in the Reregistration Eligibilty 
Decision. This mixture is registered as a preservative for 
antimicrobial control in the following use sites: Oil recovery drilling 
muds and flooding fluids; industrial adhesives and coatings (natural 
based and synthetic); latex and polymer emulsions; metalworking cutting 
fluids; latex paints; paper coatings; caulks and sealants; inks; 
pigment dispersion and pigment slurry; and textile fiber finishes that 
are not intended as clothing. Azadioxabicyclooctane has been cleared by 
the Food and Drug Administration (FDA) for use as an antibacterial 
preservative in paper and paperboard products that are limited to dry 
food contact only in 21 CFR 176.180 as well as a component in paper 
adhesives in 21 CFR 175.105.
     EPA has determined that the data base to support reregistration is 
substantially complete and that products containing PHMB, 4-t, BIT and 
Aza are eligible for reregistration provided the risks are mitigated 
either in the manner described in the RED or by another means that 
achieves equivalent risk reduction. Upon submission of any required 
product specific data under section 4(g)(2)(B) and any necessary 
changes to the registration and labeling (either to address concerns 
identified in the RED or as a result of product specific data), EPA 
will make a final reregistration decision under section 4(g)(2)(C) for 
products containing PHMB, 4-t, BIT and Aza.
     Although, the RED decisions were made in FY 04 (PHMB) and FY05 (4-
t, BIT and Aza), certain components of the documents, which did not 
affect the final regulatory decisions, were undergoing final editing at 
that time. None of these additions or changes alter the conclusions 
documented in the PHMB, 4-t, BIT and Aza REDs now available for 
comment.
     EPA is applying the principles of public participation to all 
pesticides undergoing reregistration and tolerance reassessment. The 
Agency's Pesticide Tolerance Reassessment and Reregistration; Public 
Participation Process, published in the Federal Register on May 14, 
2004, (69 FR 26819)(FRL-7357-9) explains that in conducting these 
programs, EPA is tailoring its public participation process to be 
commensurate with the level of risk, extent of use, complexity of 
issues, and degree of public concern associated with each pesticide. 
Due to its uses, risks, and other factors, PHMB, 4-t, BIT and Aza were 
reviewed through the modified 4-Phase process. Through this process, 
EPA worked extensively with stakeholders and the public to reach the 
regulatory decisions for PHMB, 4-t, BIT and Aza.
     The reregistration program is being conducted under 
Congressionally mandated time frames, and EPA recognizes the need both 
to make timely decisions and to involve the public. The Agency is 
issuing the PHMB, 4-t, BIT and Aza REDs for public comment. This 
comment period is intended to provide an additional opportunity for 
public input and a mechanism for initiating any necessary amendments to 
the RED. 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 Agency Dockets for PHMB, 4-t, 
BIT and Aza. 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 and regulations.gov. If any comment significantly affects the 
document, EPA also will publish an amendment to the RED in the Federal 
Register. In the absence of substantive comments requiring changes, the 
PHMB, 4-t, BIT and Aza REDs will be implemented as they are now 
presented.

B. What is the Agency's Authority for Taking this Action?

     Section 4(g)(2) of FIFRA as amended directs that, after submission 
of all data concerning a pesticide active ingredient, ``the 
Administrator shall determine whether pesticides containing such active 
ingredient are eligible for reregistration,'' before calling in product 
specific data on individual end-use products and either reregistering 
products or taking other ``appropriate regulatory action.''
