Owner Agreement,the City understands and accepts that Ecology is under no obligation to agree to future changes requested by the City. Ecology will generally not agree to scope change requests that will result in extra cost to Ecology. This does not include standard contract changes that are required to complete the planned scope of work(e.g., Work Change Directives resulting from unforeseen circumstances or previously undiscovered features). Background This cleanup work is part of the larger Everett Smelter Cleanup. Ecology is continuing to clean up shallow arsenic contamination in areas of the Upland Area of the Everett Smelter Project Site. Site remediation and restoration of properties in the Upland Area are being performed in accordance with the 1999 Everett Smelter Site Integrated Final Cleanup Action Plan and Final Environmental Impact Statement for the Uplands Area. These activities include shallow soil removal and replacement, soil sampling, surface and landscape restoration, and any and all work activities required in connection with soil sampling or soil excavation and replacement, and topography and landscape restoration. Ecology is not removing all possible soil contamination that may be present in the Property. The purpose of this Work is to remove arsenic-contaminated soil and potentially contaminated soil from exposed surface areas where park users may come in regular, long-term contact with the contamination. Ecology received funding from the legislature (17-19 biennia budget)to complete the cleanup work in the Viola Oursler Viewpoint and Wiggums Hollow Park. These funds, and no additional Ecology funds,will be used to cover the cost of the work outlined in this agreement and the Project Manual. Cleanup and related work will be performed in accordance with the design documents and the project manuals developed by Ecology and reviewed and approved by the City of Everett.
