New Tolerance Exemptions for Inerts Except PIPS
PP IN11515. EPAHQOPP2021
0323. Spring Regulatory Sciences, 6620 Cypresswood Dr, Suite 250, Spring, TX 77379 on behalf of Nouryon Chemicals LLC, , requests to establish an exemption from the requirement of a tolerance in 40 CFR part 180.910 and 180.930 for residues of Oxirane, 2methyl-, polymer with oxirane, monoC9-11-isoalkyl ethers, C10-rich, phosphates, potassium salts CAS Reg.
No. 2275654378 when used as a pesticide inert ingredient in pesticide formulations Joint Inerts Task Force Cluster Support. The analytical method is available to EPA The petitioner believes no analytical method is needed because it is not required for an exemption from the requirement of a tolerance. Contact: RD.
