Ciba-Geigy Corp. v. EPA

Citation: 19 ELR 21281
No. No. 88-4361, 874 F.2d 277/29 ERC 1721/(5th Cir., 06/02/1989)

The court holds that under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), the Environmental Protection Agency Administrator may cancel registration of a pesticide upon a finding of significant probability that undesirable consequences to the environment may occur. The court first holds that a significant risk of bird kills, even if birds are actually killed infrequently, may justify the Administrator's decision to ban or restrict diazinon use. The court next holds that, under FIFRA § 6(b), the Administrator must determine whether the use of a pesticide in a particular application creates unreasonable risks, though not necessarily actual adverse consequences, with considerable frequency. Additionally, the Administrator must define the pesticide restriction sufficiently narrowly.
