Under a proposed legal settlement, court ordered “no-spray buffer zones” from years ago would be restored with the goal of protecting West Coast salmon and steelhead from the potential impacts of five pesticides – diazinon, chlorpyrifos, malathion, carbaryl, and methomyl – commonly used to ward off insect damage to agricultural crops and other vegetation.

Generally, the buffers established by the Court are 20 yards for ground application and 100 yards for aerial application, adjacent to certain "salmon-supporting waters" in Washington, Oregon and California. The order applies to pesticide use in these three states, for any product containing one or more of the pesticides subject to the court order.
