1,3-Dichloropropene (1,3-D) Revised Human Health Risk Assessment, 
Notice of Availability and Solicitation of Risk Reduction Options

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: This notice announces the availability and solicitation of 
comments on the EPA's revised human health risk assessment for the soil 
fumigant 1,3-Dichloropropene (1,3-D), which is commonly referred to as 
telone. In addition, this notice seeks public comment on the risk 
reduction options paper and EPA's benefits assessments for the soil 
fumigant group. The Agency is also seeking comments on the 1,3-D 
ecological risk assessment which, based on public comments in phase 3, 
was not revised. Although 1,3-D has undergone reregistration and a 
Reregistration Eligibility Decision was published in December 1998, EPA 
is concurrently assessing six soil fumigants to ensure that its risk 
assessment approaches are consistent, and to ensure that risk tradeoffs 
and economic outcomes can be adequately predicted in reaching risk 
management decisions for the five other soil fumigants. The Agency is 
seeking the same input from the public on these pesticides. EPA has 
developed a revised human health risk assessment for 1,3-D and is 
seeking comment through a public participation process in order to make 
available current and accurate information on this pesticide.

DATES: Comments must be received on or before July 2, 2007.

II. Background

A. What Action is the Agency Taking?

    EPA is making available the Agency's revised human health risk 
assessment, initially issued for comment through a Federal Register 
notice published on July 13, 2005 (70 FR 40342) (FRL-7721-9); a 
response to comments; and related documents for 1,3-D. EPA also is 
soliciting public comment on the risk reduction options paper and the 
benefits assessments for the soil fumigant group. 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).
    1,3-D is applied to control root-knot nematodes and certain pests 
and diseases in the soil prior to the planting of a variety of food and 
feed crops including vegetables, fruits, nuts, and other field and 
nursery crops. In addition there is a proposed new use for post-plant 
drip irrigation in established vineyards. 1,3-D is also a restricted 
use pesticide and as such can only be applied by certified applicators 
or those under the supervision of a certified applicator. End-use 
product formulations containing 1,3-D may be applied through drip 
irrigation or by injection below the soil surface either in rows or 
broadcast across an area.

[[Page 24299]]

    1,3-D was deemed eligible for reregistration in December 1998. The 
volatility of 1,3-D in the environment and results of metabolism 
studies in plants assure that there is no reasonable expectation of 
finite residues to be incurred in/on any raw agricultural commodities 
when end-use product formulations containing 1,3-D are applied 
according to label directions. Therefore, this fumigant does not 
require food tolerances.
    EPA is providing an opportunity, through this notice, for 
interested parties to provide risk management proposals or otherwise 
comment on risk management for the soil fumigant group. A complete list 
of the mitigation options can be found in the following document, 
``Risk Mitigation Options to Address Bystander and Occupational 
Exposures from Soil Fumigant Applications,'' docket number EPA-HQ-OPP-
2005-0124-0048. A Reader's Guide has been created to provide an 
organizational structure to the 1,3-D Docket, to allow readers to more 
easily access and navigate the various entries contained in the 1,3-D 
Docket, and to facilitate public comment. You will find this guide at 
EPA-HQ-OPP-2005-0124-0046. 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.
    Although 1,3-D has undergone reregistration, the Agency plans to 
follow a similar public participation process for the human health 
revised risk assessment to ensure that the risk assessment approaches 
are consistent, and that risk management decisions for the five other 
soil fumigants consider the relative risks and benefits of each 
chemical. While the Agency does not anticipate making changes to the 
decisions made in the 1998 RED, if, at the conclusion of the soil 
fumigant assessment and risk management process, EPA determines that it 
is appropriate to modify its 1998 risk mitigation decision for 1,3-D 
considering the relative risks and benefits of others, EPA may relax 
certain measures or consider adding new ones.
    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 1,3-D. Comments 
received after the close of the comment period will be marked ``late'' 
EPA is not required to consider these late comments.

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.''
    1,3-D was deemed eligible for reregistration in December 1998. EPA 
has developed a revised human health risk assessment for 1,3-D to 
assess the proposed post-plant use in established vineyards, and also 
in order to make available current and accurate information on this 
pesticide which will be considered as EPA assesses risk and develops 
risk management decisions for the five other soil fumigants.
