Federal Human Health Criteria for Washington State Waters

On November 14, 2022, EPA Administrator Regan signed a rule to restore the protective and science-based federal human health criteria (HHC) for the state of Washington’s waters that EPA had originally promulgated in 2016 but later removed in 2020. This decision reflects the agency’s commitment to protect people who consume fish from Washington’s waters, including tribes with treaty-protected subsistence fishing rights, and to apply sound science under the Clean Water Act.
