King County and the City of Seattle have committed to reduce overall use of pesticides on public lands. To meet this end, the city and county have created an Integrated Pest Management (IPM) policy and guidelines.
A driving force behind the new policy was the Endangered Species Act and listing of Chinook salmon.The city and county have devised a three-tier hazard-ranking system for chemicals that control weeds and other pests. Targeted for elimination
by June 2000 are so-called "Tier 1" products (the most hazardous), which contain known carcinogens and which are highly toxic to birds, fish or animals or which quickly seep into groundwater.IPM is a holistic approach to pest (including weed) management. The IPM process combines the use of biological, cultural, physical, and chemical tactics in a manner that strives to minimize economic, health, and environmental risks.
Technical groups were formed to respond to provisions of the Endangered Species Act (ESA) and they made recommendations for the reduction of pesticide usage by participating jurisdictions. The Tri-County IPM technical group, headed by King County Hazardous Waste Group and City of Seattle Office of Environmental Management, developed a model policy and guidelines for use by local jurisdictions. These documents are listed below, along with the group's final report.

Environmental Purchasing Program
The King County Environmental Purchasing Program assists County agencies in implementation of King County Executive Policy CON-7-1-2, which requires agencies to use recycled and other environmentally preferable products wherever practicable.
The program assembles information about these products and makes it available to specific agency users who can evaluate them and develop applications in County projects.
These environmental purchasing bulletins contain information about the results of product evaluations and other accomplishments of County agencies. We hope this information will help you find ways to use recycled materials in the work of your agency and that you will contact us if we can help you with further information or if you have suggestions.
