Response to Comments CEMEX Final Supplemental Environmental Impact Statement November 30, 2009 Chapter 4 Soils and Drainage Comments with City Responses Comments are arranged by topic, in chronological order by date received, with most recent listed first. 34. Kathy Pierson Snohomish Health District Ms. Pierson has provided a soils report in the possession of the Heath District showing the location on the CEMEX site of approximately 44,031 tons of soils contaminated with Arsenic and Cadmium and an additional 271,253 tons of soil contaminated with elevated PH < 13, a petroleum based contaminant. The noted "inert waste" soils are buried an average of 35 feet below grade, and are located at the north end of the site near the SW corner of the intersection of Glenwood Avenue at Merrill Creek Parkway. In the recent past CEMEX accepted the soils from four public off-site sources and allowed them to be transported to the site for burial and storage, in accordance with State and Health District regulations. At this time the State Departments of Ecology and Natural Resources is aware of these soils being stored on site, and the Snohomish County Health District has issued a permit (Solid Waste Facility Permit #SW -204) to CEMEX for storage of this material. See Appendix A, public comment file, correspondence dated October 6, 2009 from the Heath District. Related documents follow that initial correspondence. Response: The City has been in contact with the Heath District regarding allowed uses at (over, on top of) the contaminated soil storage location and any other details that may be relevant to future use of this specific location and the overall CEMEX site generally, as it relates to possible reuse of the site in the future. There will be conditions / restrictions on what can be built on the material that would have to be reviewed by the Health District and the State Department of Ecology.
