Inc. 11335 NE 122nd Way Suite 100 Kirkland, Washington U.S.A. 98034-6918 Tel (206) 820-4669 Fax (206) 821-3914 Subject: Street Use Permit for Borings In Shoulder of Federal Avenue Dear Mr. McKee: AGRA Earth and Environmental, Inc. (AEE) on behalf of Mobil Oil Corporation and the American Distributing Company has been approved to perform work in accordance with them draft Agreed Order No. DE 95TC-N402 with the Washington Department of Ecology. Included in the work to be performed is an assessment of subsurface environmental conditions along the combined sewer overflow (CSO) line between manholes SMH U3 and SML T2 (Figure 1). The assessment will include advancing a number of 2-inch diameter soil probes to depths of 40 to 15 feet for the purpose of collecting soil samples. The sampling probes will be advanced using a van mounted Geoprobe unit. Soil probes advanced in areas where the soil appears to have been impacted substantially by petroleum hydrocarbons will be fitted with f - inch diameter PVC piezometers. The piezometers would be fitted with a flush mounted surface seal to protect them from traffic and infiltration of surface runoff. The piezometers would be periodically gauged over an eight week period after which time they would be removed and the surface restored. We anticipate that two to four of the probes will be advanced in the shoulder of Federal Avenue. We therefore request that the City of Everett issue a street use permit to allow this work to be performed in the shoulder of the road. Traffic control measures to be implemented during this work are shown in Figures 2 and 3. 0� Engineering & Environmental Services
