Dimethyldithiocarbamate Salts; Amendment to Ziram and Ferbam 
Reregistration Eligibility Decisions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.


SUMMARY: This notice announces EPA's decision to amend the 2003 and 
2005 Reregistration Eligibility Decisions (RED) documents for the 
antimicrobial pesticides Ziram and Ferbam (Reregistration Case 2180). 
EPA conducted a reassessment of the Ziram and Ferbam REDs upon learning 
that the salts Potassium Dimethyldithiocarbamate and Sodium 
Dimethyldithiocarbamate were not evaluated at the same time as the rest 
of case 2180. The Agency has conducted a risk assessment and issued a 
RED addendum for the Dimethyldithiocarbamate Salts, which were 
inadvertently not included in the 2003 and 2005 Reregistration 
Eligibility Decision documents for Ziram and Ferbam. This notice opens 
an additional 60-day public comment period for Dimethyldithiocarbamate 
Salts because a previous comment period for the Risk Assessment portion 
of this addendum was restricted to registrants only.

DATES: Comments must be received on or before November 16, 2009.

(ID) number EPA-HQ-OPP-2009-0321, by one of the following methods:

I. General Information

A. Does this Action Apply to Me?

    This action is directed to the public in general, and may be of 
interest to a wide range of stakeholders including environmental, human 
health, and agricultural advocates; the chemical industry; pesticide 
users; and members of the public interested in the sale, distribution, 
or use of pesticides. Since others also may be interested, the Agency 
has not attempted to describe all the specific entities that may be 
affected by this action. If you have any questions regarding the

B. What Should I Consider as I Prepare My Comments for EPA?

     1.  Submitting CBI. Do not submit this information to EPA through 
regulations.gov or e-mail. Clearly mark the part or all of the 
information that you claim to be CBI. For CBI information in a disk or 
CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM as 
CBI and then identify electronically within the disk or CD-ROM the 
specific information that is claimed as CBI. In addition to one 
complete version of the comment that includes information claimed as 
CBI, a copy of the comment that does not contain the information

Information so marked will not be disclosed except in accordance with 
procedures set forth in 40 CFR part 2.
    2. Tips for preparing your comments. When submitting comments,

    i. Identify the document by docket ID number and other identifying 
information (subject heading, Federal Register date and page number).
    ii. Follow directions. The Agency may ask you to respond to 
specific questions or organize comments by referencing a Code of 
Federal Regulations (CFR) part or section number.
    iii. Explain why you agree or disagree; suggest alternatives and 
substitute language for your requested changes.
     iv. Describe any assumptions and provide any technical information 
and/or data that you used.
    v. If you estimate potential costs or burdens, explain how you 
arrived at your estimate in sufficient detail to allow for it to be 
    vi. Provide specific examples to illustrate your concerns and

II. Background

A. What Action is the Agency Taking?

    Section 4 of the Federal Insecticide, Fungicide, and Rodenticide 
Act (FIFRA) directs EPA to reevaluate existing pesticides to ensure 
that they meet current scientific and regulatory standards. In 2003 and 
2005, EPA issued REDs for Ziram and Ferbam, respectively, under section 
4(g)(2)(A) of FIFRA. The associated Dimethyldithiocarbamate Salts RED 
reflects the evaluation of the final two active ingredients in case 
2180, which were inadvertently not included in the 2003 and 2005 Ziram 
and Ferbam Reregistration Eligibility Decision documents, as well as 
efforts by the Agency to appropriately mitigate overall risk. The RED 
amendment for Ziram and Ferbam concludes EPA's reregistration 
eligibility decision-making process for these pesticides.
    The Agency evaluated Sodium Dimethyldithiocarbamate and Potassium 
Dimethyldithiocarbamate and determined that products containing 
Dimethyldithiocarbamate Salts are eligible for reregistration, provided 
that the risk mitigation measures identified within the 
Dimethyldithiocrabmante Salts RED addendum are adopted and labels are 
amended accordingly. The label table incorporated into the 
Dimethyldithiocarbamate Salts RED addendum includes modifications which 
specify label language for protecting occupational handlers from 
inhalation exposure to powdered end-use products, as well as amending 
the environmental hazards statement for clarity.

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.''
