All fertilizer products distributed in Washington must first be registered with WSDA. An additional registration requirement for waste-derived fertilizers was added to the fertilizer law in 1998. Waste-derived and micronutrient fertilizers must go through a Department of Ecology (Ecology) review before being registered by WSDA. All registration applications must first be submitted to WSDA. WSDA will forward information to Ecology for further review on an as-needed basis.
To register a fertilizer, please refer to the checklist below:
As part of the registration process, the registrant must identify those products that are waste-derived fertilizers, micronutrient fertilizers, or a fertilizer material containing phosphate. In addition, waste-derived fertilizers and micronutrient fertilizers shall include information to determine if the product complies with the Ecology Hazardous Waste Management law, Chapter 70.105 RCW, and the Environmental Protection Agency's Resource Conservation and Recovery Act, 42 U.S.C. Sec. 6901 et seq. For further information on these laws, contact Tom Cusack, Department of Ecology , at (360) 407-6755.
Before registering a waste-derived fertilizer or micronutrient fertilizer, WSDA must obtain written approval from the Department of Ecology as provided in RCW 15.54.820 of the Fertilizers, Minerals and Limes law. Once a waste-derived fertilizer or micronutrient fertilizer has been approved by Ecology, its subsequent use in another product during that registration cycle shall not require that agency's review.
Any commercial fertilizer distributed in Washington must have a label attached to the package which provides the following information:
If a commercial fertilizer is distributed in bulk, a written or printed statement meeting the labeling requirements must accompany delivery and be supplied to the purchaser at the time of delivery. This includes truckloads and railcar loads.
Each delivery of a customer-formula fertilizer must contain those ingredients specified by the purchaser. The fertilizer must be accompanied by either a statement, invoice, a delivery slip, or a label if bagged, containing the following information: The net weight; the brand; the name and amount of each ingredient; the guaranteed analysis which may be stated to the nearest tenth of a percent or to the next lower whole number; the name and address of the registrant or licensee, or manufacturer, or both; and the name and address of the purchaser. The registrant or licensee must maintain a record of all invoices of customer-formula grade mixes for twelve months and must make them available to the department upon request.
