5 AMENDMENT NO. 8 TO DEPARTMENT OF ECOLOGY REMEDIAL ACTION GRANT AGREEMENT NO. G0200099 BETWEEN STATE OF WASHINGTON DEPARTMENT OF ECOLOGY AND CITY OF EVERETT PURPOSE: To amend the above-referenced grant agreement between the Department of Ecology (DEPARTMENT)and City of Everett(RECIPIENT). In order to allow additional funding for the perimeter gas control system and funding for three new tasks; Task 5—Background Determination for Fe,Mn, As and Cl, Task 6—Well Abandonment,and Task 7—Gas Monitoring for the Everett Landfill, IT IS MUTUALLY AGREED that the grant agreement is amended as follows: A. The total Maximum Eligible Cost is hereby increased by$200,000 from $2,738,144 to a new total of$2,938,144. B. The State Grant Share is hereby increased by $100,000 from $1,369,072 to a new total of $1,469,072. C. A new Project Task 5, 6 and 7 is hereby added to the Scope of Work of the grant agreement. 5. PROJECT TASK: BACKGROUND DETERMINATION FOR Fe, Mn, As, and Cl Maximum Eligible Cost: $50,000 Schedule: December 31, 2006 Project Description: The RECIPIENT shall conduct a groundwater background investigation for iron(Fe), manganese(Mn), and arsenic (As) levels around the Everett Landfill site. This task includes siting, installing, and sampling of new wells in a similar hydrogeological environment as the landfill, but outside the influence of the landfill to establish background samples. Ten samples will be taken over a year's period at the revised background site for Fe, Mn, and As. An additional background evaluation will be conducted for chloride levels (Cl)near MW 37. The background evaluation will be a localized study due to the likelihood of higher chloride levels as a result of salt-water intrusion to the well. The evaluation will include looking at river levels,chloride levels and potentially the hydrogeology between the landfill's east edge and the Snohomish River. lof4
