Propylene Oxide (PPO) Reregistration Eligibility 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 propylene oxide (PPO), and 
opens a public comment period on this document. This comment period is 
intended to provide an additional opportunity for public input; in 
particular, the Agency is seeking comments regarding what additional 
measures, beyond emission control techniques, are available to protect 
bystanders from unsafe exposure to PPO resulting from use in vacuum-
sealed pressurized chambers. The Agency's risk assessments and other 
related documents also are available in the PPO docket. PPO is an 
insecticidal fumigant/sterilant used both to control bacteria 
contamination, mold contamination, insect infestations, and microbial 
spoilage of food products as well as to control stored product insects 
in nonfood products. PPO is registered for use on several food items 
such as processed spices, cocoa (beans and

[[Page 45556]]

powder), and in-shell and processed nutmeats (except peanuts). PPO also 
has nonfood uses for cosmetic articles, gums, ores, packaging, 
pigments, pharmaceutical materials, and discarded nutshells prior to 
disposal. EPA has reviewed PPO 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, PPO under section 4(g)(2)(A) of FIFRA. PPO is an 
insecticidal fumigant/sterilant used both to control bacteria 
contamination, mold contamination, insect infestations, and

[[Page 45557]]

microbial spoilage of food products as well as to control stored 
product insects in nonfood products. PPO is registered for use on 
several food items such as processed spices, cocoa (beans and powder), 
and in-shell and processed nutmeats (except peanuts). PPO also has 
nonfood uses for cosmetic articles, gums, ores, packaging, pigments, 
pharmaceutical materials, and discarded nutshells prior to disposal. 
EPA has determined that the data base to support reregistration is 
substantially complete and that products containing PPO are eligible 
for reregistration provided the risks are mitigated in the manner 
described in the RED. 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 PPO.
    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 PPO tolerances.
    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, PPO was reviewed through the 
modified 4-Phase process. Through this process, EPA worked extensively 
with stakeholders and the public to reach the regulatory decisions for 
PPO.
    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 PPO 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. In order to protect bystanders, 
the RED requires emission control technologies, such as scrubbers or 
acid bubblers, which achieve a performance standard of 99% emission 
reduction of PPO from vacuum-sealed pressurized chambers. However, the 
Agency is also interested in receiving comments describing other means 
to protect bystanders from this use. 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 PPO. 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 
PPO 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.
