chemistry described by CAS Reg. No. 1266162-49-5 is covered by the published tolerance exemption for alkyl amines polyalkoxylates and that no further data or review is required to amend the existing tolerance ex emption. A Notice of Filing for this petition was published in the Federal Register on March 14, 2012 (77 FR 15012). There were no comments received in response to this notice.

The purpose of this document is to assess, as required under the Federal Food Drug and Cosmetic Act (FFDCA), the risk of the use of CAS Reg. No. 1266162-49-5 as an inert ingredient in pesticide produc ts and is based on a previous assessment for alkyl amines polyalkoxylates and a rationale provided by the petitione r as to why CAS Reg. No.

1266162-49-5 can be considered safe under the descriptor fo r alkyl amines polyalkoxylates; under 40 CFR 180.920 & 180.930.

A previous assessment was completed on April 3, 2009 and a final rule establishing an exemption from the requirement of a to lerance for residues of alkyl amines polyalkoxylates under 40 CFR 180.920 & 180.930 was published on June 17, 2009 (74 FR 28616). This exemption was established based on information s ubmitted by the Joint Inert Task Force Cluster Support Team 4 (J ITF CST 4) in response to a final rule published on August 9, 2006 (71 FR 45415) in which the Agency revoked, under section 408(e)(1) of the Federal Food, Drug and Cosmet ic Act (FFDCA), the existing exemptions from the requirement of a tolerance for residues of certain inert FFDCA section 408(b)(2).

Specific information on the studies received fr om JITF CST 4 to support the request to establish an exemption from the requirement a tolerance and the nature of the adverse effects caused by alkyl amine pol yalkoxylates as well as the no- observed-adverse-effectlevel (NOAEL) and the lowest-observed-advers e-effect- level (LOAEL) from the toxicity studies can be found at http:// www.regul ations.gov in document “Alkyl Amine Polyalkoxylates (JITF CST 4 Inert Ingredie nts), Human Health Risk Assessment to Support Proposed Exemption from the Requireme nt of a Tolerance When Used as Inert Ingredients in Pesticide Formulations,” at pages 10-17 in docket ID number EPA– HQ–

OPP–2008–0738.

The Agency has reviewed BASF’s claim that the addition of CAS Reg. No. 1266162-49- 5 is acceptable under the curr ent tolerance exemption de scriptor for alkyl amine polyalkoxylates. IIAB has confirmed that the requested CAS Reg. No. is acceptable for

consideration under the curren tly approved descriptor and that no further review is required. The requested compound is a N,N-Bis- α -ethyl- ω -hydroxypoly(oxy-1,2- ethanediyl) C10 saturated alkyl amine and, as such, falls within the existing tolerance exemption descriptor of N,N-Bis- α -ethyl- ω -hydroxypoly(oxy-1,2-ethanediyl) C8-C18 saturated and unsaturated alkylamines; th e poly(oxy-1,2-ethanediyl content is 2-60 moles. The Agency has determined that the use of CAS Reg. No. 1266162-49-5 is adequately supported by the existing data a nd assessment for alkyl amine polyalkoxylates

and that no additional data or review is required.Taking into consideration a ll available information, EPA concludes that there is a reasonable certainty of no harm to the gene ral population or to in fants and children from aggregate exposure to CAS Reg. No. 1266162-49-5 wh en used as an inert ingredient in pesticide formulations. Therefore, the am endment of the existing exemption from the requirement of tolerance under 40 CFR 180.920 and 180.930 for N,N-Bis- α -ethyl- ω

hydroxypoly(oxy-1,2-ethanediyl) C8-C18 saturate d and unsaturated alkylamines; the poly(oxy-1,2-ethanediyl cont ent is 2-60 moles to include CAS Reg. No. 1266162-49-5

can be considered safe u nder section 408 of the FFDCA.
