Pesticide Tolerances; Implementing Registration Review Decisions for Certain Pesticides; Maleic Hydrazide, et al.

The Environmental Protection Agency (EPA or Agency) is finalizing several pesticide tolerance actions under the Federal Food, Drug, and Cosmetic Act (FFDCA) that the Agency previously determined were necessary or appropriate during the registration review conducted under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). During registration review, EPA reviews all aspects of a pesticide case, including existing tolerances, to ensure that the pesticide continues to meet the standard for registration under FIFRA. The Agency is also finalizing tolerance actions identified outside of registration review as housekeeping measures, such as removing expired tolerances from the Code of Federal Register (CFR). The pesticide tolerances and active ingredients addressed in this rulemaking are identified and discussed in detail in Unit III. of this document.
