II. Background

A. What Action is the Agency Taking?

    EPA has reassessed the uses of propazine, reassessed four existing 
tolerances or legal residue limits, and on April 6, 2006, reached a 
tolerance reassessment decision for this low risk chlorinated triazine 
pesticide. The Agency is now issuing for comment the resulting Report 
onFood Quality Protection Act (FQPA) Tolerance Reassessment Progress 
and Risk Management Decision for propazine, known as a TRED, as well as 
related risk assessments and technical support documents. Propazine is 
a systemic herbicide that is usually applied to the soil, absorbed 
through leaves and roots, and acts by inhibiting photosynthesis within 
the targeted plant. It isused as a selective herbicide to control most 
annual grasses and broadleaf weeds before the weeds emerge or after 
removal of weed growth. Propazine is formulated as a flowable 
concentrate, is registered for use on container grown ornamentals in 
greenhouses, and is to be applied through flood or drench nozzles only. 
The Agency has received a new use petition forsorhgum from the Griffin 
Corporation (PP 7F4837 as announced in a Federal Register Notice 
published on June 22, 2005, 70 FR 36159), and potential risks resulting 
from this use will be assessed when the petition is considered.
    EPA developed the propazine TRED through a modified, streamlined 
version of its public process for making tolerance reassessment and 
reregistration eligibility decisions. Through these programs, the 
Agency is ensuring that pesticides meet current standards under the 
Federal Food, Drug, and Cosmetic Act (FFDCA) and the Federal 
Insecticide, Fungicide, andRodenticide Act (FIFRA), as amended by FQPA. 
EPA must review tolerances and tolerance exemptions that were in effect 
when FQPA was enacted, 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 propazine 
tolerances included in this notice. EPA has determined that the data 
base to support propazine tolerance reassessment is substantially 
complete and that propazine tolerances meet the FFDCA safety standard.
     The propazine TRED presents the Agency's tolerance reassessment 
conclusions for propazine alone; however, section 408(b)(2)(D)(v) of 
FFDCA directs the Agency also to consider available information on the 
cumulative risk from substances sharing a common mechanism of toxicity. 
Propazine shares a neuroendocrine mechanism of toxicity, which results 
in both reproductive and developmental consequences, with the 
structurally-related chlorinated triazine pesticides atrazine and 
simazine. Because these chlorinated triazine pesticides share a common 
mechanism of toxicity, the Agency evaluated the cumulative risk posed 
by this group while making final tolerance reassessment decisions on 
individual chlorinated triazines. However, propazine was not 
incorporated into the cumulative risk assessment because no dietary, 
drinking water, or residential human exposure to propazine is 
anticipated from any of the currently registered uses.
     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, the Agency 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. 
EPA can expeditiously reach decisions for pesticides like propazine, 
which pose no risk concerns, have low use, affect few stakeholders, and 
require no risk mitigation. Once EPA assesses uses and risks for such 
low risk pesticides, the Agency may go directly to a decision and 
prepare a document summarizing its findings, such as the propazine 
TRED.
    The tolerance reassessment program is being conducted under 
Congressionally mandated time frames, and EPA recognizes the need both 
to make timely decisions and to involve the public in finding ways to 
effectively mitigate pesticide risks. Propazine, however, poses no 
risks that require mitigation. The Agency therefore is issuing the 
propazine TRED, its risk assessments, and related support documents 
simultaneously for public comment. The commentperiod is intended to 
provide an opportunity for public input and a mechanism for initiating 
any necessary amendments to the TRED. All comments should be submitted 
using the methods in Unit I. of the SUPPLEMENTARY INFORMATION, and must 
be received by EPA on or before the closing date. These comments will 
become part of the Agency Docket for propazine. Comments received after 
the close of the comment period will be marked ``late.'' EPA is not 
required to consider these late comments.
    EPA 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 TRED in the Federal Register. 
In the absence of substantive comments requiring changes, the decisions 
reflected in the TRED will be implemented as presented.

B. What is the Agency's Authority for Taking this 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.
     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), and (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), and 
(c)(2)(B).
