The residential exposure scenario used in the non-cancer aggregate assessment of children 1 to less than 2 years old is the combined inhalation and hand-to-mouth exposures from short-term post-application exposure to indoor perimeter/spot coarse and pin stream surface spray applications on carpet. This prototype edition of the Section 408(b)(2)(C) of FFDCA requires EPA to give special consideration to exposure of infants and children to the pesticide chemical residue in establishing a tolerance and to ensure that there is a reasonable certainty that no harm will result to infants and children from aggregate exposure to the pesticide chemical residue. Tolerances are also established for residues of broflanilide, including its metabolites and degradates, in or on the following livestock commodities: Cattle, fat at 0.02 ppm; Cattle, meat at 0.02 ppm; Cattle, meat byproducts at 0.02 ppm; Egg at 0.02 ppm; Goat, fat at 0.02 ppm; Goat, meat at 0.02 ppm; Goat, meat byproducts at 0.02 ppm; Hog, fat at 0.02 ppm; Hog, meat at 0.02 ppm; Hog, meat byproducts at 0.02 ppm; Horse, fat at 0.02 ppm; Horse, meat at 0.02 ppm; Horse, meat byproducts at 0.02 ppm; Milk at 0.02 ppm; Poultry, fat at 0.02 ppm; Poultry, meat at 0.02 ppm; Poultry, meat byproducts at 0.02 ppm; Sheep, fat at 0.02 ppm; Sheep, meat at 0.02 ppm; and Sheep, meat byproducts at 0.02 ppm.

EPA assessed residential exposure using the following assumptions: The PODs for the oral and inhalation routes are based on the same effects: Therefore, oral and inhalation routes can be combined. Thus, the Agency estimates risk in terms of the probability of an occurrence of the adverse effect expected in a lifetime. In the elimination process, the concentration of broflanilide rapidly decreased within two days and slowly dropped below the limit of quantification after ten days.
