This rule expands the tolerance for residues of hydroprene, [(S)-(Ethyl (2E,4E,7S)-3,7,11-trimethyl-2,4-odecadienoate)], an insect growth regulator, on all food items in food-handling establishments to include perimeters and pantries, and warehouses to the list of permissible food storage sites and ultra low volume (ULV) fogging as a permissible treatment method under certain precautions and conditions. This rule also permits the use of point source device treatments providing those devices do not come into direct contact with food preparation surfaces and are kept a minimum distance of 3 feet from exposed foods. This rule also restricts the tolerance expression to residues of [(S)-(Ethyl(2E,4E,7S)-3,7,11-trimethyl 2,4- dodecadienoate)], the S-racemer of hydroprene since the R-racemer is no longer being supported in reregistration.
