This regulation establishes temporary tolerances for residues of sulfuryl fluoride and inorganic fluoride in or on walnuts and raisins. The Agency is establishing these temporary tolerances under the Federal Food, Drug, and Cosmetic Act, as amended by the Food Quality Protection Act of 1996 to support an Experimental Use Permit (EUP) that involves testing a possible alternative to methyl bromide in the post-harvest fumigation of stored commodities. This experimental use fumigant program is being proposed as a methyl bromide alternative for the post-harvest fumigation of stored walnuts and raisins. These temporary tolerances will support a 3-year EUP effective between March 1, 2002 through March 1, 2005 and allows 18 months for treated commodities to clear commerce. The EUP will be conducted by Dow AgroSciences entirely in the state of California. The temporary tolerances expire on September 1, 2006. A detailed risk assessment for the proposed use was published in the Federal Register on September 5, 2001 (66 FR 46415).
