pesticide under the provisions of these rules if the person who manages the material  
knows the amount of active ingredient in the material or can estimate the largest possible  
amount of active ingredient in the material being managed either because of having direct  
knowledge of the amount of pesticide that is contained in the material or as a result of  
testing the material. Application of material for which the amount of active ingredient  
is unknown or cannot be estimated is prohibited.

Page 9  
laws shall be considered to be in compliance with the label directions for disposal,  
even if a method of disposal or handling that is used is not specified in the instructions  
for disposal on the pesticide label.  
(4) Soils, sediments, debris, or other solids that contain pesticides that may have  
been altered as a result of a fire or other occurrence shall not be used as a pesticide

used as a pesticide.  
(5) Spills, leaks, releases, or other accidental discharges of pesticides or pesticide-  
containing materials shall be promptly contained and recovered in a manner that assures  
the protection of human health and the environment. Surfaces that intercept such  
discharges shall be promptly cleaned to assure maximum recovery. Recovered  
pesticides and pesticide-containing materials and materials that are used to contain,  
minimize, absorb, or collect spills shall be managed in accordance with subrule (1)(a) of  
this rule.  
(6) A person shall not dispose of or handle any pesticide or any pesticide-  
containing material as follows:  
(a) In a manner that is inconsistent with its labeling.  
(b) So as to cause or allow a discharge to the environment in a manner that is  
inconsistent with the label instructions for use or disposal.  
(c) So as to violate any state or federal pollution control statute.  
(d) So as to cause or allow burying in a land site in a manner that is not in  
compliance with applicable state and federal solid waste regulations.  
(e) So as to cause or allow the storage of pesticides or pesticide-containing

R 285.637.10 Off-target pesticide drift.  
Rule 10. (1) Pesticide applications shall be made in a manner that minimizes off-  
target drift, unless prior authorization and consent as specified in subrule (3) of this  
rule is obtained from the owner or resident of the land onto which drift may occur.  
(2) Before making a pesticide application, an applicator shall do both of the following:  
(a) Determine the likelihood of off-target drift.  
(b) Determine the direction of possible off-target drift and any sensitive areas that  
may be impacted.  
(3) When pesticide off-target drift is likely to occur due to the nature of the application  
or atmospheric conditions, including, but not limited to wind speed and direction, a drift  
management plan shall be utilized by the applicator to minimize the occurrence and  
adverse effects of off-target drift. The plan shall include provisions to secure the  
informed consent of residents in the affected area before making the application. If, in  
the course of making an application off-target drift occurs, the applicator shall notify the  
residents in the affected area either verbally or with written notification which includes  
the name, address, and phone number of a person who may be contacted and who is  
responsible for supplying information concerning the application before leaving the  
application site. The drift management plan shall include drift minimization practices.  
Such practices may include any of the following:  
(a) The use of a possible combination of nozzles, pressure, or volume to manage  
droplet size.  
(b) The use of equipment that is designed to minimize off-target drift.  
(c) The consideration of release distance to target to maximize deposition.  
(d) The use of drift reduction additives.  
(e) The establishment of a no-spray buffer zone. The buffer zone may be treated with  
nonpowered equipment.  
(f) The identification of the maximum wind speed and direction under which  
applications can be made.  
(g) The use of wind shields or windbreaks to contain spray drift or deflect spray  
drift.  
(h) Other specific measures stated in the plan that are effective in minimizing the  
incidence of off-target drift.  
(4) Drift management plans shall be in writing. The plan will state the measures to be  
used and how those measures will reduce off-target drift. The drift management plan  
shall be annually reviewed by the person who utilizes the plan.  
(5) A record of the sites where the drift management plan was implemented and a copy  
of the drift management plan shall be retained for a period of 1 year for general use  
Page 11  
pesticides and 3 years for restricted use pesticides and shall be made available to the  
director upon request.  
(6) Operating under a drift management plan does not exempt an applicator from  
complying with appropriate federal or state statutes and regulations.However, the  
department shall consider the presence and use of a drift management plan as a factor  
in determining appropriate enforcement action.
