    (2) Piperonyl butoxide may be safely used in accordance with the 

following prescribed conditions:

    (i) It is used or intended for use in combination with pyrethrins 

for control of insects:

    (A) In cereal grain mills and in storage areas for milled cereal 

grain products, whereby the amount of piperonyl butoxide is at least 

equal to but not more than 10 times the amount of pyrethrins in the 

formulation.

    (B) On the outer ply of multiwall paper bags of 50 pounds or more 

capacity in amounts not exceeding 60 milligrams per square foot, whereby 

the amount of piperonyl butoxide is equal to 10 times the amount of 

pyrethrins in the formulation. Such treated bags are to be used only for 

dried foods.

    (C) On cotton bags of 50 pounds or more capacity in amounts not 

exceeding 55 milligrams per square foot of cloth, whereby the amount of 

piperonyl butoxide is equal to 10 times the amount of pyrethrins in the 

formulation. Such treated bags are constructed with waxed paper liners 

and are to be used only for dried foods that contain 4 percent fat or 

less.

    (D) In two-ply bags consisting of cellophane/polyolefin sheets bound 

together by an adhesive layer when it is incorporated in the adhesive. 

The treated sheets shall contain not more than 50 milligrams of 

piperonyl butoxide per square foot (538 milligrams per square meter). 

Such treated bags are to be used only for packaging prunes, raisins, and 

other dried fruit and are to have a maximum ratio of 3.12 milligrams of 

piperonyl butoxide per ounce of fruit (0.10 milligram of piperonyl 

butoxide per gram of product).

    (E) In food processing and food storage areas: Provided, That the 

food is removed or covered prior to such use.

    (ii) It is used or intended for use in combination with pyrethrins 

and N-octylbicycloheptene dicarboximide for insect control in accordance 

with 21 CFR 178.3730.

    (iii) A tolerance of 10 parts per million is established for 

residues of piperonyl butoxide in or on:

    (A) Milled fractions derived from Grain, cereal when present therein 

as a result of its use in cereal grain mills and in storage areas for 

milled cereal grain products.

    (B) Dried foods when present as a result of migration from its use 

on the outer ply of multiwall paper bags of 50 pounds or more capacity.

    (C) Foods treated in accordance with 21 CFR 178.3730.

    (D) Dried foods that contain 4 percent fat, or less, when present as 

a result of migration from its use on the cloth of cotton bags of 50 

pounds or more capacity constructed with waxed paper liners.

    (E) Foods treated in accordance with paragraph (a)(2)(i)(D) and (E) 

of this section.

    (iv) To assure safe use of the pesticide, its label and labeling 

shall conform to that registered with the U.S.



[[Page 345]]



Environmental Protection Agency, and it shall be used in accordance with 

such label and labeling.

    (v) Where tolerances are established on both raw agricultural 

commodities and processed foods made therefrom, the total residues of 

piperonyl butoxide in or on the processed food shall not be greater than 

that permitted by the larger of the two tolerances.

    (3) Piperonyl butoxide may be safely used in accordance with the 

following prescribed conditions:

    (i) It is used or intended for use in combination with pyrethrins 

for control of insects:

    (A) On the outer ply of multiwall paper bags of 50 pounds or more 

capacity in amounts not exceeding 60 milligrams per square foot.

    (B) On cotton bags of 50 pounds or more capacity in amounts not 

exceeding 55 milligrams per square foot of cloth. Such treated bags are 

constructed with waxed paper liners and are to be used only for dried 

feeds that contain 4 percent fat or less.

    (ii) It is used in combination with pyrethrins, whereby the amount 

of piperonyl butoxide is equal to 10 times the amount of pyrethrins in 

the formulation. Such treated bags are to be used only for dried feeds.

    (iii) A tolerance of 10 parts per million is established for 

residues of piperonyl butoxide when present as the result of migration:

    (A) In or on dried feeds from its use on the outer ply of multiwall 

paper bags of 50 pounds or more capacity.

    (B) In or on dried feeds that contain 4 percent fat, or less, from 

its use on cotton bags of 50 pounds or more capacity constructed with 

waxed paper liners.

    (iv) To assure safe use of the pesticide, its label and labeling 

shall conform to that registered with the U.S. Environmental Protection 

Agency.

    (v) Where tolerances are established on both the raw agricultural
