FW: SeaTac fill criteria email chain with attachments

Notes

An email chain forwarded by Ann Kenny of the Washington Department of Ecology to Andrea Grad in response to a public disclosure request. The emails detail draft fill criteria requirements for the 401 Water Quality Certification for the SeaTac Third Runway Embankment project, including spreadsheets and documentation for soil cleanup levels. The draft document outlines fill source requirements, documentation standards, and environmental assessment criteria for imported fill materials.
