Subject of Possible Rule Making: Increase the maximum allowed tank size for pesticide temporary field storage containers used for soil fumigants.

Statutes Authorizing the Agency to Adopt Rules on this Subject: Pesticide Control Act, chapter 15.58 RCW and the Pesticide Application Act, chapter 17.21 RCW.

Reasons Why Rules on this Subject may be Needed and What They Might Accomplish: The current rule (WAC 16-229-010) limits the size of pesticide temporary field storage containers to 2,500 gallons. This limitation has become a concern of applicators and growers who are using soil fumigants. Soil fumigants are often used at rates of fifteen to twenty-five gallons per acre and higher. A large percentage of soil fumigant users grow upwards of four hundred acres of crops often on the same farm. Given the rate per acre, number of acres to be treated, the current tank size are inadequate in that the field storage tanks will have to be filled several times. Larger tanks would present a greater degree of safety than smaller tanks for the following reasons. Spills are most likely to occur during transfer from trucks into temporary field storage tanks. It is less hazardous to have an operator empty a 5,000 gallon tank truck into a field storage tank that can hold that capacity rather than a tank that can hold half that capacity.

The current 2,500 gallon restriction results in a substantial increase in the number of times the product is transferred, increasing the risk of accidental spills. Larger tank allowances would reduce the number of road miles in the delivery of soil fumigants.

Without an increase in the allowable tank size for field storage dealers will be forced to make multiple trips to and from the tanks, increasing exposure of trucks to transportation accidents.

Other Federal and State Agencies that Regulate this Subject and the Process Coordinating the Rule with These Agencies: Environmental Protection Agency (EPA). The EPA regulates the use of pesticides primarily through the pesticide label. EPA has delegated WSDA Pesticide Management Division as the state lead agency for the enforcement of pesticide regulations in Washington state. EPA will be apprised during the entire rule-making process and be offered an opportunity to provide comments.

Department of Ecology (DOE). DOE will be apprised during the entire rule-making process and be offered an opportunity to provide comments.

Process for Developing New Rule: A technical advisory committee consisting of key stakeholders will be established as an aid in developing a new rule if necessary.

Interested parties can participate in the decision to adopt the new rule and formulation of the proposed rule before publication.
