II. What Action is the Agency Taking?

EPA has received a pesticide petition as follows proposing the establishment and/or amendment of regulations for residues of a certain pesticide chemical in or on various food commodities under section 408 of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a. EPA has determined that this petition contains data or information regarding the elements set forth in section 408(d)(2); however, EPA has not fully evaluated the sufficiency of the submitted data at this time or whether the data support granting of the petition. Additional data may be needed before EPA rules on the petition.

Summary of Petition

The petitioner summary of the pesticide petition is printed below as required by section 408(d)(3) of the FFDCA. The summary of the petition was prepared by the petitioner and represents the view of the petitioner. The petition summary announces the availability of a description of the analytical methods available to EPA for the detection and measurement of the pesticide chemical residues or an explanation of why no such method is needed.

Wacker Silicones Corporation

PP 5E4430

EPA has received a pesticide petition (PP 5E4430) from Wacker Silicones Corporation, 3301 Sutton Road, Adrian, Michigan 49221-9397 proposing, pursuant to section 408(d) of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a(d), to amend 40 CFR part 180.1001(c) to amend the existing exemption from the requirement of a tolerance for dimethylpolysiloxane in or on the raw agricultural commodities when used as an inert ingredient in pesticide formulations which were applied to the growing crop and/or after harvest. EPA has determined that the petition contains data or information regarding the elements set forth in section 408(d)(2) of the FFDCA; however, EPA has not fully evaluated the sufficiency of the submitted data at this time or whether the data supports granting of the petition. Additional data may be needed before EPA rules on the petition.

The Agency has established a set of criteria which identifies categories of polymers that present low risk. These criteria (described in 40 CFR 723.250) identify polymers that are relatively unreactive and stable compounds compared to other chemical substances as well as polymers that typically are not readily absorbed. These properties generally limit polymer's ability to cause adverse effects. The Agency believes that polymers meeting the criteria noted above will present minimal or no risk. Dimethylpolysiloxane conforms to the definition of polymer given in 40 CFR 723.250(b) and meets the following criteria that are used to identify low risk polymers.

1. Dimethylpolysiloxane is not a cationic polymer, nor is it reasonably anticipated to become a cationic polymer in the natural aquatic environment.

2. Dimethylpolysiloxane contains as an integral part of its composition the atomic elements carbon, hydrogen, oxygen and silicon.

3. Dimethylpolysiloxane does not contain as an integral part of its composition, except as impurities, any element other than those listed in 40 CFR 723.250 (d)(2)(ii).

4. Dimethylpolysiloxane is not reasonably anticipated to substantially degrade, decompose or depolymerize.

5. Dimethylpolysiloxane is not manufactured or imported from monomers and/or other reactants that are not already included on the TSCA Chemical Substance Inventory or manufactured under an applicable TSCA section 5 exemption.

6. Dimethylpolysiloxane is not a water absorbing polymer with a number average molecular weight greater than or equal to 10,0000 daltons.

7. Dimethylpolysiloxane has a molecular weight ranging from 10,148 daltons to 61,380 daltons. Dimethylpolysiloxane meets the requirements for molecular weight distribution of oligomer contents of less than 5%% with molecular weights less than 1,000 and less than 2% with molecular weights less than 500.

A. Aggregate Exposure

1. Dietary exposure. Dimethylpolysiloxane is not absorbed through the skin or GI tract generally and is considered incapable of eliciting a toxic response.

i. Food. Dimethylpolysiloxane is approved for use as a food additive under 21 CFR Parts 24.246, 175.105, 175.125, 175.300, 175.320, 175.380, 175.390, 176.200, 176.170, 176.180, 176.200, 177.1200, 177.1210, 177.1350, 177.2260, 177.2800, 178.3120, 178.3570, 178.3910, and 181.28.

ii. Drinking water. Based upon the aqueous insolubility of dimethylpolysiloxane, there is no reason to expect human exposure to residues in drinking water.

2. Non-dietary exposure. Although there may be exposures to the compound though dietary and non-occupational non-dietary routes, the chemical characteristics of the chemical are such that there is a reasonable certainty of no harm from aggregate exposure.

B. Cumulative Effects

There are no data to support cumulative risk from dimethylpolysiloxane since polymers with molecular weights greater than 400 generally are not absorbed through the intact skin and substances with molecular weights greater than 1,000 generally are not absorbed through the gastrointestinal tract (GI). Chemical not absorbed through the skin or GI tract generally are incapable of eliciting a toxic response. Therefore, there is no reasonable expectation of risk due to cumulative exposure.

C. Safety Determination

1. U.S. population. Dimethylpolysiloxane causes no safety concerns because it conforms to the Start Printed Page 55242definition of a low risk polymer given in 40 CFR 723.250(b) and as such is considered incapable of eliciting a toxic response. Also, there are no additional pathways of exposure (non-occupational, drinking water, etc.) where there could be additional risk.

2. Infants and children. Dimethylpolysiloxane causes no additional concern to infants and children because it conforms to the definition of a low risk polymer given in 40 CFR 723.250(b), and as such, is considered incapable of eliciting a toxic response. Also, there are no additional pathways of exposure (non-occupational, drinking water, etc.) where infants and children would be at additional risk.

D. International Tolerances

There are no CODEX Maximum Residue Limits established for dimethylpolysiloxane in/on any crop commodities at this time.
