The U.S. Environmental Protection Agency has given pesticide manufacturers two weeks to make changes to help protect threatened and endangered northwest salmon and steelhead.
The National Marine Fisheries Service 18 months ago found the pesticides diazinon, malathion and chlorpyrifos to be harmful to 27 species of salmon and steelhead in the West.
The EPA has sent a letter to the manufacturers of these pesticides requesting that they voluntarily allow the labels of their products to be changed.
If the companies don't comply by May 13th, the EPA will take legal action.
Aimee Code with the Northwest Coalition for Alternatives to Pesticides, says this is a step in the right direction.
Aimee Code: "If the government holds strong, this is going to create a legacy of cleaner water and it's going to make sure that our salmon populations are protected, but we need our government to hold strong at this time."
The federal agency suggests buffer strips up to one thousand feet along salmon streams where the pesticides should not be sprayed.
Anti-pesticide groups had sued to get the EPA to better regulate these chemicals.
