Sec. 156.146  Residue removal instructions for nonrefillable containers--

rigid containers with dilutable pesticides.

    The label of each dilutable (liquid or solid) pesticide product 
packaged in a rigid nonrefillable container must include the following 
residue removal instructions as appropriate.
    (a) Timing of the residue removal procedure. One of the following 
statements

[[Page 73]]

must immediately precede the instructions required in paragraph (b) of 
this section and must be consistent with the instructions in paragraphs 
(b) and (c) of this section:
    (1) ``Clean container promptly after emptying.''
    (2) ``Triple rinse or pressure rinse container (or equivalent) 
promptly after emptying.''
    (3) ``Triple rinse container (or equivalent) promptly after 
emptying.''
    (b) Triple rinse instructions. The label of each dilutable pesticide 
product packaged in rigid nonrefillable containers must include one of 
the following sets of instructions.
    (1) For liquid dilutable pesticide products in containers small 
enough to shake, use the following instructions: ``Triple rinse as 
follows: Empty the remaining contents into application equipment or a 
mix tank and drain for 10 seconds after the flow begins to drip. Fill 
the container 1/4 full with water and recap. Shake for 10 seconds. Pour 
rinsate into application equipment or a mix tank or store rinsate for 
later use or disposal. Drain for 10 seconds after the flow begins to 
drip. Repeat this procedure two more times.''
    (2) For solid dilutable pesticide products in containers small 
enough to shake, use the following instructions: ``Triple rinse as 
follows: Empty the remaining contents into application equipment or a 
mix tank. Fill the container 1/4 full with water and recap. Shake for 10 
seconds. Pour rinsate into application equipment or a mix tank or store 
rinsate for later use or disposal. Drain for 10 seconds after the flow 
begins to drip. Repeat this procedure two more times.''
    (3) For containers that are too large to shake, use the following 
instructions: ``Triple rinse as follows: Empty remaining contents into 
application equipment or a mix tank. Fill the container 1/4 full with 
water. Replace and tighten closures. Tip container on its side and roll 
it back and forth, ensuring at least one complete revolution, for 30 
seconds. Stand the container on its end and tip it back and forth 
several times. Turn the container over onto its other end and tip it 
back and forth several times. Empty the rinsate into application 
equipment or a mix tank or store rinsate for later use or disposal. 
Repeat this procedure two more times.''
    (c) Pressure rinse instructions. The label of each dilutable 
pesticide product packaged in rigid nonrefillable containers may include 
one of the following sets of instructions, and one of them must be used 
if the statement in paragraph (a)(2) of this section is used. If one of 
these statements is included on the label, it must immediately follow 
the triple rinse instructions specified in paragraph (b) of this 
section.
    (1) For liquid dilutable pesticide products, use the following label 
instruction: ``Pressure rinse as follows: Empty the remaining contents 
into application equipment or a mix tank and continue to drain for 10 
seconds after the flow begins to drip. Hold container upside down over 
application equipment or mix tank or collect rinsate for later use or 
disposal. Insert pressure rinsing nozzle in the side of the container, 
and rinse at about 40 PSI for at least 30 seconds. Drain for 10 seconds 
after the flow begins to drip.''
    (2) For solid dilutable pesticide products, use the following label 
instruction: ``Pressure rinse as follows: Empty the remaining contents 
into application equipment or a mix tank. Hold container upside down 
over application equipment or mix tank or collect rinsate for later use 
or disposal. Insert pressure rinsing nozzle in the side of the 
container, and rinse at about 40 PSI for at least 30 seconds. Drain for 
10 seconds after the flow begins to drip.''
    (d) Non-water diluent. (1) A registrant who wishes to require users 
to clean a container with a diluent other than water (e.g., solvents) 
must submit to EPA a written request to modify the residue removal 
instructions of this section. The registrant may not distribute or sell 
the pesticide with the modified residue removal instructions until EPA 
approves the request in writing.
    (2) The registrant must indicate why a non-water diluent is 
necessary for efficient residue removal, and must propose residue 
removal instructions and disposal instructions that are appropriate for 
the characteristics and formulation of the pesticide product and

[[Page 74]]

non-water diluent. The proposed residue removal instructions must 
identify the diluent. If the Directions for Use permit the application 
of a mixture of the pesticide and the non-water diluent, the 
instructions may allow the rinsate to be added to the application 
equipment or mix tank. If the Directions for Use do not identify the 
non-water diluent as an allowable addition to the pesticide, the 
instructions must require collection and storage of the rinsate in a 
rinsate collection system.
    (3) EPA may approve the request if EPA finds that the proposed 
instructions are necessary and appropriate.
