An emergency under this section may be declared if the director determines that the situation is:
(a) Urgent and unexpected; and
(b) The risk and amount of economic harm to the crop substantially outweighs the risk and amount of damage likely to occur to the environment if a variance permit is issued.
(2) Application for a permit may be made by email to compliance@agr.wa.gov or by mail, fax, or in person to the Washington State Department of Agriculture, Pesticide Management Division, Natural Resources Building (NRB), Second Floor, 1111 Washington St. S.E., P.O. Box 42560, Olympia, WA 98504-2560, FAX: 360-902-2093. Permits will not be granted by telephone.
(3) The department may make on-site monitoring of the application a condition of any permit. A representative of the department may condition, deny, or revoke a permit at any time, if the representative determines that the situation at the application site creates an unreasonable risk. In determining whether the situation at the application site creates an unreasonable risk, the representative may consider all relevant factors such as temperature, tides, precipitation, application type, pesticide formulation and application equipment, ditch cover condition, endangered species restrictions, air inversions, time of day, burning restrictions, wind direction, wind velocity, topography, and type and condition of application equipment.
