Chlorpyrifos; Tolerance Revocation. Proposed rule

EPA is proposing to revoke all tolerances for residues of chlorpyrifos, except for those associated with the use of chlorpyrifos on the following crops: alfalfa, apple, asparagus, tart cherry, citrus, cotton, peach, soybean, strawberry, sugar beet, and spring and winter wheat. This proposal also addresses the request to revoke all chlorpyrifos tolerances contained in the 12 September 2007, petition.
