                  Subpart D_Exemptions From Tolerances
 
Sec. 180.940  Tolerance exemptions for active and inert ingredients for 

use in antimicrobial formulations (Food-contact surface sanitizing 
solutions).

    Residues of the following chemical substances are exempted from the 
requirement of a tolerance when used in accordance with good 
manufacturing practice as ingredients in an antimicrobial pesticide 
formulation, provided that the substance is applied on a semi-permanent 
or permanent food-contact surface (other than being applied on food 
packaging) with adequate draining before contact with food.
    (a) The following chemical substances when used as ingredients in an 
antimicrobial pesticide formulation may be applied to: Food-contact 
surfaces in public eating places, dairy-processing equipment, and food-
processing equipment and utensils.
