The use of herbicides on the following sites does not require coverage under any aquatic pesticide permits issued by Ecology: 1.Man-made detention or retention ponds designed specifically for wastewater or stormwater treatment that do not have an outlet to surface waters of the state,or ponds that will not discharge to other water bodies during and for two weeks following treatment. 2.Upland farm ponds with no discharge to other surface waters of the state during,and for two weeks following treatment. 3.Any constructed water body five acres or less in surface area with no discharge to other surface waters of the state during or for two weeks following treatment. 4.Any noxious weed activities conducted on seasonally dry land surfaces (including seasonally dry wetlands)as long as the active ingredient is not biologically active when the water returns. 5.Any research activities when pesticides or adjuvants are being applied to lakes under a state experimental use permit(sites are less than one acre in size)
