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 pesticide, MCPB under section 4(g)(2)(A) of FIFRA. MCPB is a phenoxy herbicide used for post-emergence weed control to protect pea crops from a variety of weeds including canadian thistle, common lambsquarters, pigweed, smartweed, sowthistle, and morning glory. There are no registered residential uses of MCPB. EPA has determined that the data base to support reregistration is substantially complete and that products containing MCPB 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 MCPB. EPA must review tolerances and tolerance exemptions that were in effect when the Food Quality Protection Act (FQPA) was enacted in August 1996, to ensure that these existing pesticide residue limits for food and feed commodities meet the safety standard established by the new law. Tolerances are considered reassessed once the safety finding has been made or a revocation occurs. EPA has reviewed and made the requisite safety finding for the MCPB tolerances included in this notice. EPA is applying the principles of public participation to all pesticides VerDate Aug<31>2005 20:36 Jun 20, 2006 Jkt 208001 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, MCPB was reviewed through the modified 4-Phase proceess. Through this process, EPA worked extensively with stakeholders and the public to reach the regulatory decisions for MCPB. 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 MCPB RED 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 Docket for MCPB. 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 MCPB RED will be implemented as it is 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.’’ Section 408(q) of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a(q), requires EPA to review tolerances and exemptions for pesticide residues in effect as of August 2, 1996, PO 00000 Frm 00063 Fmt 4703 Sfmt 4703 35669 to determine whether the tolerance or exemption meets the requirements of section 408(b)(2) or (c)(2) of FFDCA.

Simazine is widely used as a selective herbicide and registered for use on a variety of food and feed crops, including, but not limited to, fruit and nut crops in addition to corn. Simazine can also be applied at forestry sites and on turfgrass grown commercially for sod. Simazine is registered for residential use on turfgrass including both commercial use on recreational lawns such as golf courses and commercial or homeowner use on lawns. An algaeicide use exists for ornamental ponds and aquariums of 1,000 gallons or less. End-use products containing simazine are formulated as pellets/tablets, dry flowables, emulsifiable concentrates, flowable concentrates, and ready-to-use liquids. These product formulations may be applied on the ground by broadcast across an area, as a spot treatment, or in rows, which is also referred to as band treatment. The simazine RED presents the Agency’s conclusions on the risks posed by exposure to simazine alone; however, section 408(b)(2)(D)(v) of the Federal Food, Drug and Cosmetic Act (FFDCA) directs the Agency also to consider available information on the cumulative risk from substances sharing a common E:\FR\FM\21JNN1.SGM 21JNN1 jlentini on PROD1PC65 with NOTICES Federal Register / Vol. 71, No. 119 / Wednesday, June 21, 2006 / Notices mechanism of toxicity. Simazine shares a neuroendocrine mechanism of toxicity, which results in both reproductive and developmental consequences, with the structurallyrelated chlorinated triazine pesticides atrazine and propazine. Because these chlorinated triazine pesticides share a common mechanism of toxicity, the Agency evaluated the cumulative risk posed by this group while making final reregistration eligibility decisions on individual chlorinated triazines. EPA has determined that the data base to support reregistration is substantially complete and that products containing simazine 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 simazine.

The Agency’s Pesticide Tolerance Reassessment and Reregistration; Public Participation Process, published in the Federal Register of 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 refined risk assessment and the relatively limited risk management issues associated with this pesticide, simazine was reviewed through the modified four-phase process. Through this process, EPA worked extensively with stakeholders and the public to reach the regulatory decisions for simazine. The reregistration program is being conducted under Congressionally VerDate Aug<31>2005 18:26 Jun 20, 2006 Jkt 208001 mandated time frames, and EPA recognizes the need both to make timely decisions and to involve the public.

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 Docket for simazine. 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 will also publish an amendment to the RED in the Federal Register. In the absence of substantive comments requiring changes, the simanzine RED will be implemented as it is now presented. B. What is the Agency’s Authority for Taking this Action? Section 4(g)(2)(A) of FIFRA, as amended, requires the Aministrator to make ‘‘a determination as to the eligibility for reregistration (i) for all active ingredients subject to reregistration under this section for which tolerances or exemptions from tolerances are required under the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 301 et seq.), not later than the last date for tolerance reassessment established under section 408(q)(1)(C) of that Act (21 U.S.C. 346a(q)(1)(C)) . . . .’’ 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. A tolerance or exemption meets the requirements of section 408(b)(2) or (c)(2), respectively, if ‘‘the Administrator determines [the pesticide chemical residue] is safe’’, i.e., ‘‘that there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue, including all anticipated dietary exposures and all other exposures for which there is reliable information.’’ 21 U.S.C. 346a(b)(2)(A), (c)(2)(A).

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 
chlorinated triazine pesticide, simazine, under section 4(g)(2)(A) of 
FIFRA. Simazine is widely used as a selective herbicide and registered 
for use on a variety of food and feed crops, including, but not limited 
to, fruit and nut crops in addition to corn. Simazine can also be 
applied at forestry sites and on turfgrass grown commercially for sod. 
Simazine is registered for residential use on turfgrass including both 
commercial use on recreational lawns such as golf courses and 
commercial or homeowner use on lawns. An algaeicide use exists for 
ornamental ponds and aquariums of 1,000 gallons or less. End-use 
products containing simazine are formulated as pellets/tablets, dry 
flowables, emulsifiable concentrates, flowable concentrates, and ready-
to-use liquids. These product formulations may be applied on the ground 
by broadcast across an area, as a spot treatment, or in rows, which is 
also referred to as band treatment.
    The simazine RED presents the Agency's conclusions on the risks 
posed by exposure to simazine alone; however, section 408(b)(2)(D)(v) 
of the Federal Food, Drug and Cosmetic Act (FFDCA) directs the Agency 
also to consider available information on the cumulative risk from 
substances sharing a common

[[Page 35671]]

mechanism of toxicity. Simazine shares a neuroendocrine mechanism of 
toxicity, which results in both reproductive and developmental 
consequences, with the structurally-related chlorinated triazine 
pesticides atrazine and propazine. Because these chlorinated triazine 
pesticides share a common mechanism of toxicity, the Agency evaluated 
the cumulative risk posed by this group while making final 
reregistration eligibility decisions on individual chlorinated 
triazines.
    EPA has determined that the data base to support reregistration is 
substantially complete and that products containing simazine 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 simazine.
    EPA must review tolerances and tolerance exemptions that were in 
effect when the Food Quality Protection Act (FQPA) was enacted in 
August 1996, to ensure that these existing pesticide residue limits for 
food and feed commodities meet the safety standard established by the 
new law. Tolerances are considered reassessed once the safety finding 
has been made or a revocation occurs. EPA has reviewed and made the 
requisite safety finding for the simazine tolerances included in this 
notice.
    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 of 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 refined risk assessment and the relatively limited risk 
management issues associated with this pesticide, simazine was reviewed 
through the modified four-phase process. Through this process, EPA 
worked extensively with stakeholders and the public to reach the 
regulatory decisions for simazine.
    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 simazine 
RED 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 
Docket for simazine. 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 will also publish an amendment to the RED in the Federal 
Register. In the absence of substantive comments requiring changes, the 
simanzine RED will be implemented as it is now presented.

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

     Section 4(g)(2)(A) of FIFRA, as amended, requires the Aministrator 
to make ``a determination as to the eligibility for reregistration (i) 
for all active ingredients subject to reregistration under this section 
for which tolerances or exemptions from tolerances are required under 
the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 301 et seq.), not 
later than the last date for tolerance reassessment established under 
section 408(q)(1)(C) of that Act (21 U.S.C. 346a(q)(1)(C)) . . . .''
    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. A tolerance or exemption meets 
the requirements of section 408(b)(2) or (c)(2), respectively, if ``the 
Administrator determines [the pesticide chemical residue] is safe'', 
i.e., ``that there is a reasonable certainty that no harm will result 
from aggregate exposure to the pesticide chemical residue, including 
all anticipated dietary exposures and all other exposures for which 
there is reliable information.'' 21 U.S.C. 346a(b)(2)(A), (c)(2)(A). In 
making this safety finding, FFDCA requires the Administrator to 
consider, among other factors, ``available information concerning the 
cumulative effects of such residues and other substances that have a 
common mechanism of toxicity . . . .'' 21 U.S.C. 346a(b)(2)(D)(v), 
(c)(2)(B).
