Decision; Notice of Availability

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: This notice announces the availability of EPA's Reregistration 
Eligibility Decision (RED) for the pesticide PCNB, and opens a public 
comment period on this document. The Agency's risk assessments and 
other related documents also are available in the PCNB Docket. PCNB is 
an organochlorine fungicide used to control plant diseases on 
vegetables (predominantly green beans and cole crops), field crops 
(cotton, potatoes, and peanuts), and seeds (seed treatments of barley, 
beans, corn, cotton, oats, peas, peanut, rice, safflower, sorghum, 
soybean, sugar beet, and wheat). EPA has reviewed PCNB through the 
public participation process that the Agency uses to involve the public 
in developing pesticide reregistration and tolerance reassessment 
decisions. Through these programs, EPA is ensuring that all pesticides 
meet current health and safety standards.

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 
pesticide, PCNB under section 4(g)(2)(A) of FIFRA. PCNB is an 
organochlorine fungicide used to control plant diseases on vegetables 
(predominantly green beans and cole crops), field crops (cotton, 
potatoes, and peanuts), and seeds (seed treatments of barley, beans, 
corn, cotton, oats, peas, peanut, rice, safflower, sorghum, soybean, 
sugar beet, and wheat). EPA has determined that the data base to 
support reregistration is substantially complete and that products 
containing PCNB are eligible or not eligible for reregistration 
depending on their specific uses. Most uses of PCNB have been found to 
be ineligible for reregistration. These uses are: turf, residential 
ornamentals, cole crops (unless registered for control of clubroot 
only), green beans, cotton, potatoes, dry beans and peas, garlic, 
peanuts, tomatoes, peppers, and ornamentals in commercial production 
(except for flowering bulbs). The following uses of PCNB are eligible 
for reregistration provided the risk mitigation measures noted in the 
RED are implemented and product labels are amended accordingly: cole 
crops (registered for control of clubroot only), ornamental bulbs for 
commercial production, and seed treatments of PCNB. 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 PCNB.
    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 PCNB 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 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, PCNB was reviewed through 
the full 6-Phase process. Through this process, EPA worked extensively 
with stakeholders and the public to reach the regulatory decisions for 
PCNB.
    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 PCNB 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

[[Page 43748]]

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 PCNB. Comments received after the 
close of the comment period will be marked ``late.'' EPA is not 
required to consider these late comments.In particular, during the 60-
day comment period following the publication of this Notice, the Agency 
is soliciting comments on the benefits associated with several minor 
uses of PCNB. The Agency has based its reregistration eligibility 
decision for most uses of PCNB on an evaluation of the risk-benefit 
relationships for those uses. The Agency is soliciting information on 
benefits for specific minor uses of PCNB in order to confirm that the 
Agency's reregistration decisions for these uses are supported by an 
accurate understanding of their risk-benefit relationships, and to 
determine if amendments should be made to this eligibility decision 
based on comments which inform these risk-benefit evaluations. The 
specific kinds of benefits information that the Agency believes will be 
helpful in this regard and the specific uses for which the Agency is 
soliciting such information are discussed below.The use sites of PCNB 
for which the Agency is soliciting information on benefits at this time 
are: dry beans and peas, peanuts, tomatoes, peppers (all types), and 
ornamentals in commercial production (all types except for flowering 
bulbs). The types of information that the Agency believes could be 
useful in informing the risk-benefit evaluations for these uses include 
data from comparative efficacy trials for different pesticides used to 
control diseases on these sites, information about the relative costs 
of using PCNB and potential alternatives, production cost data, 
information on why registered alternatives are not appropriate for 
specific diseases in a particular State or under particular climatic 
conditions, and documentation of the lack of alternatives for 
controlling a particular disease.
    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 
PCNB 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, 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.
