Metam Sodium and Metam Potassium; 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 seeks comments on 
EPA's revised human health risk assessment for the pesticide fumigants 
metam sodium and metam potassium. In addition, this notice solicits 
public comment on the risk reduction options paper for fumigants 
including metam sodium and metam potassium and EPA's benefits 
assessments for the soil fumigants. The Agency is also seeking comments 
on the ecological risk assessment which was not revised since the last 
public comment period. The public is encouraged to suggest risk 
management ideas or proposals to address the risks identified. EPA is 
developing a Reregistration Eligibility Decision (RED) for metam sodium 
and metam potassium through the full, 6-Phase public participation 
process that the Agency uses to involve the public in developing 
pesticide reregistration and tolerance reassessment decisions. EPA also 
is concurrently assessing the risks of four other soil fumigant 
pesticides to ensure that its assessment approaches are consistent, and 
to ensure that risk tradeoffs and economic outcomes can be adequately 
predicted in reaching risk management decisions. The Agency is seeking 
the same input from the public on these pesticides on a similar 
schedule. Through these programs, EPA is ensuring that all pesticides 
meet current health and safety standards.

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 and ecological risk assessment, initially issued for comment 
through a Federal Register notice published on July 13, 2005, (70 FR 
40333) (FRL-7722-1); a response to comments; and related documents for 
metam sodium and metam potassium. EPA also is soliciting public comment 
on the risk reduction options paper and benefits assessments for the 
soil fumigants. EPA developed the risk assessments for metam sodium and 
metam potassium as part of its public process for making pesticide 
reregistration eligibility and tolerance reassessment decisions. 
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).
    Metam sodium and metam potassium are non-selective pre-plant soil 
fumigants with fungicidal, herbicidal, insecticidal, and nematicidal 
properties. They are registered for use on all food, feed and fiber 
crops including turf and ornamentals. Metam sodium's major agricultural 
use sites include potatoes, carrots, tomatoes, onions, and peanuts. 
Metam potassium's major use sites are lettuce, potatoes, onions, 
tomatoes, and watermelons. Metam sodium is also registered for use in 
orchard replant, on golf course turf, and for small areas of turf and 
soil. In addition, metam sodium is used as a root-control agent in 
drains and sewers. Metam sodium and metam potassium are also registered 
for a variety of antimicrobial and industrial uses. Metam sodium and 
metam potassium are converted to methyl isothiocyanate (MITC) in the 
environment, particularly in the presence of moisture (such as in soil 
after application). It is MITC that performs the fumigating activity. 
The volatility of metam sodium and metam potassium 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 commodity when the products are applied according to label 
directions.
    EPA is providing an opportunity, through this notice, for 
interested parties to provide risk management proposals or otherwise 
comment on risk management for metam sodium and metam potassium. Risks 
of concern associated with the use of metam sodium and metam potassium 
include

[[Page 24292]]

bystander and worker risks. A complete list of the risks and the 
mitigation options can be found in the Risk Mitigation Options Document 
docket number EPA-HQ-OPP-2005-0125. A Readers Guide has been created to 
provide an organizational structure to the metam sodium and metam 
potassium docket, to allow readers to more easily access and navigate 
the various entries contained in the metam sodium and metam potassium 
docket, and to facilitate public comment. You may find this guide in 
docket number EPA-HQ-OPP-2005-0125. In targeting these risks of 
concern, the Agency solicits information on effective and practical 
risk reduction measures.
    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, metam sodium and metam 
potassium are being reviewed through the full 6-Phase public 
participation process.
    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 metam sodium and 
metam potassium. Comments received after the close of the comment 
period will be marked ``late'' EPA is not required to consider these 
late comments.
    After considering comments received, EPA will develop and issue the 
metam sodium and metam potassium RED.

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.''
