| Description | In 1998 the WA State Department of Ecology developed a total maximum daily load (TMDL) plan to clean up suspended sediment and DDT in the lower Yakima River valley. This TMDL, along with a companion evaluation report clearly protected aquatic species but were less precise about DDT levels that would be required to protect human health. Because the relationship between turbidity, suspended sediment, and DDT would likely change significantly after most of the suspended sediment was removed from the river, the TMDL intended to identify specific human health load allocations for DDT starting in 2007.__After a second review of the TMDL in 2004, EPA determined that water bodies in the TMDL that were not meeting human health standards for DDT would still need a TMDL. This update applied EPA’s determination to the TMDL by reference and detailed Ecology’s subsequent actions. | ||||
