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.

Uniqema

0E6197

EPA has received a pesticide petition (PP0E6197) from Uniqema, 900 Uniqema Boulevard, New Castle, DE 19720 proposing, pursuant to section 408(d) of the FFDCA, 21 U.S.C. 346a(d), to amend 40 CFR part 180 to establish an exemption from the requirement of a tolerance for modified styrene-acrylic polymers. 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.

A. Residue Chemistry

Magnitude of residues. Uniqema is petitioning that modified styrene-acrylic polymers be exempt from the requirement of a tolerance based upon their compliance with the low risk polymer criteria per 40 CFR 723.250. Therefore, an analytical method to determine residues in raw agricultural commodities has not been proposed. No residue chemistry data or environmental fate data are presented in the petition as the Agency does not generally require some or all of the listed studies to rule on the exemption from the requirement of a tolerance for a low risk polymer inert ingredient.

B. Toxicological Profile

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 compared to other chemical substances as well as polymers that typically are not readily absorbed. Uniqema believes that modified styrene-acrylic polymers conform to the definition of a polymer given in 40 CFR 723.250 and meet the criteria used to identify a low risk polymer. Uniqema also believes that based on this substance's conformance to the above mentioned criteria, no mammalian toxicity is anticipated from dietary, inhalation or dermal exposure to emulsion polymers and that emulsion polymers will present minimal or no risk.

1. This polymer is not a cationic substance.

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

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

4. This polymer is not designed or reasonably anticipated to substantially degrade, decompose, or depolymerize.

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

6. It is not a water absorbing polymer.

7. The minimum average molecular weight of the above mentioned polymer is greater than 1,000. Substances with molecular weights greater than 400 are generally not readily absorbed through the intact skin, and substances with molecular weights greater than 1,000 are generally not absorbed through the intact gastrointestinal (GI) tract. Chemicals not absorbed through the GI tract are generally incapable of eliciting a toxic response.

This polymer has an oligomer content less than 10%% below MW 500 and less than 25%% MW 1,000.

Uniqema believes sufficient information was submitted in the petition to assess the hazards of modified styrene-acrylic polymers. Based on these polymers conforming to the definition of a polymer and meeting the criteria of a low risk polymer under 40 CFR 723.250, Uniqema believes there are no concerns for risks associated with toxicity.

C. Endocrine Disruption

There is no evidence that modified styrene-acrylic polymers are endocrine disrupters. Substances 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 intact gastrointestinal (GI) tract. Chemicals not absorbed through the skin or GI tract generally are incapable of eliciting a toxic response.

EPA is not requiring information on the endocrine effects of this substance at this time; Congress has allowed 3 years after August 3, 1996, for the Agency to implement a screening program with respect to endocrine effects.

D. Aggregate Exposure

1. Dietary exposure. Some modified styrene-acrylic polymers may be used in contact with food as components of containers used to manufacture, process, or store food when regulated for such use under the FFDCA. Modified styrene-acrylic polymers with a molecular weight greater than 1,000 daltons are not readily absorbed through the intact gastrointestinal tract and are considered incapable of eliciting a toxic response.

2. Non-dietary exposure. Typical uses of modified styrene-acrylic polymers are in the paints and coatings industries as components of coatings. In these uses the primary exposure used is dermal, however, and modified styrene-acrylic polymers with a molecular weight significantly greater than 400 are not readily absorbed through the intact skin and are considered incapable of eliciting a toxic response.

E. Cumulative Effects

There are data to support a conclusion of negligible cumulative risk modified styrene-acrylic polymers. 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 intact GI tract. Chemicals not absorbed through the skin or GI tract generally are incapable of eliciting a toxic response. Therefore, there is no reasonable expectation of increased risk due to cumulative exposure. Based on this polymer conforming to the definition of a polymer and meeting the criteria of a low risk polymer under 40 CFR 723.250, Uniqema believes there are no concerns for risks associated with cumulative effects.

F. Safety Determination

1. U.S. population. Uniqema believes sufficient information was submitted in the petition to assess the hazards of modified styrene-acrylic polymers. Based on these polymers conforming to the definition of a polymer and meeting the criteria of a low risk polymer under 40 CFR 723.250, Uniqema believes there are no concerns for risks associated with any potential exposure to adults. There are no known additional pathways of exposure (non-occupational, drinking water, etc.) where there would be additional risk to the general population.

2. Infants and children. Uniqema believes sufficient information was submitted in the petition to assess the hazards of modified styrene-acrylic polymers. Based on these polymers conforming to the definition of a polymer and meeting the criteria of a low risk polymer under 40 CFR 723.250, Uniqema believes there are no concerns for risks associated with any potential exposure to infants and children. There are no known pathways of exposure (non-occupational, drinking water, etc.) where infants and children would be at additional risk.

G. International Tolerances

Uniqema is not aware of any country requiring a tolerance for modified styrene-acrylic polymers nor have there been any CODEX maximum residue levels established for these polymers on any food crops at this time.
