[Insert petition number]

 EPA has received a pesticide petition ([insert petition number]) from [Clariant 

Corporation], [625 E. Catawba Ave, Mt. Holly NC 28120] 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 to establish an exemption from the requirement of a 

tolerance for 

 [2-Propenoic acid, 2-methyl-, C12-16-alkyl esters, telomers with 1-

dodecanethiol, polyethylene-polypropylene glycol ether with propylene 

glycol monomethacrylate (1:1), and styrene, 2,2'-(1,2-diazenediyl)bis[2-

methylbutanenitrile]-initiated (CAS No. 950207-35-9), under 40 CFR 

180.960 when used as an inert ingredient in pesticide formulations as a 

dispersing agent.] . EPA has determined that the petition contains data or information 

regarding the elements set forth in section 408 (d)(2) of FDDCA; 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

 1. Plant metabolism.

 2. Analytical method. [Clariant Corporation is petitioning that 2-Propenoic 

acid, 2-methyl-, C12-16-alkyl esters, telomers with 1-dodecanethiol, 

polyethylene-polypropylene glycol ether with propylene glycol 

monomethacrylate (1:1), and styrene, 2,2'-(1,2-diazenediyl)bis[2-

methylbutanenitrile]-initiated be exempt from the requirement of a tolerance 

based upon the definition of a low-risk polymer under 40 CFR 723.250.

Therefore, an analytical method to determine residues on treated crops is not 

relevant.]

 3. Magnitude of residues. [Clariant Corporation is petitioning that 2-

Propenoic acid, 2-methyl-, C12-16-alkyl esters, telomers with 1-
