## Abstract

In accordance with current Agency practice to describe more clearly the measurement and scope or coverage of the tolerances, EPA is making minor revisions to tolerance expressions for a number of pesticide active ingredients, including the insecticides chlorethoxyfos, clofentezine, cyromazine, etofenprox, fenbutatin-oxide, fosthiazate, propetamphos, and tebufenozide; the fungicide aluminum tris (O-ethylphosphonate); the herbicides butylate, clethodim, clomazone, fenoxaprop-ethyl, flumetsulam, flumiclorac pentyl, fluridone, glufosinate ammonium, lactofen, propyzamide, quinclorac, and pyridate; and the fungicide/bactericide oxytetracycline. Also, EPA is revoking the tolerances for aluminum tris (O-ethylphosphonate) on pineapple fodder and forage because they are not considered to be significant livestock feed items, and revising specific tolerance nomenclatures for aluminum tris (O-ethylphosphonate), clethodim, flumetsulam, and fluridone. In addition, EPA is removing several expired tolerances for aluminum tris (O-ethylphosphonate), etofenprox, propyzamide, and tebufenozide.
