# 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.

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, remember to:                

                    i. Identify the document by docket ID number and other identifying information (subject heading,                     **Federal Register**                     date and page number).

v. If you estimate potential costs or burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced.

vi. Provide specific examples to illustrate your concerns and suggest alternatives.

vii. Explain your views as clearly as possible, avoiding the use of profanity or personal threats.

## 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.”
