Description: The layer includes facilities that reported generating large quantities of federally regulated hazardous waste or state regulated dangerous waste during either the 2022 or 2023 calendar year, as reported to the Washington State Department of Ecology. These facilities are primarily classified as Large Quantity Generators (LQGs) under federal and state hazardous waste regulations. In addition to these regulatory-based identifications, the dataset also includes a limited number of facilities that were brought to attention through community reports of concern over chemical waste and associated risks.
