(a) All certified pesticide applicators shall store all pesticide concentrates and dilute mixtures using methods which are reasonably calculated to prevent the contamination of other products by means of volatilization, leakage, breakage or other causes, and which are reasonably calculated to avoid the creation of an unreasonable risk of harm to persons, property, domestic/wild animals, or the environment.
(b) Pesticide storage areas shall be kept clean and orderly, and pesticide containers shall be positioned so that they are not exposed to unreasonable risk of damage to the containers or their labels.
(c) Pesticides and pesticide containers shall be covered or otherwise protected from the elements, in a manner which is reasonably calculated to minimize the risk of damage to labels, and to avoid the creation of an unreasonable risk of harm to persons, property or domestic/wild animals.
(d) Until such time as the department promulgates specific rules and regulations governing the storage and disposal of pesticides and pesticide containers, the RECOMMENDED procedures detailed in 40 CFR, part 165 promulgated by the Administrator, U.S. EPA, shall be the recommended procedures for Wyoming.
