2009 Asbestos Monitoring <br /> Test date:March 26,2009 <br /> 7.0 Introduction <br /> Allied Waste Industries, Inc. (AWII) operates the Forward Landfill in Manteca,California. <br /> AWH has contracted Shaw Environmental, Inc. (Shaw)to conduct semi-annual sampling of <br /> asbestos concentrations at the Forward Landfill as required by Forward Landfill Solid Waste <br /> Facility Permit 39-AA-0015. This report represents the first of two semiannual monitoring <br /> events for 2009. Asbestos was not detected at any of the sample locations. As a true baseline <br /> asbestos level cannot be established the action trigger level would be 5 micrograms per cubic <br /> ' meter above the detection limit. <br /> Representative sampling locations near the asbestos operations area were identified assuming <br /> that the sample pool would demonstrate worst case scenario concentrations. Five sampling <br /> stations,one of which included a duplicate sample,were located predominantly downwind and <br /> ' approximately 84 to 200 feet from the asbestos area with a sixth station co-located with one of <br /> the downwind stations. One of the stations was located predominantly upwind and <br /> approximately 90 feet from the asbestos area. Sampling was performed during normal weather <br /> and operating conditions. The upwind and downwind locations were chosen based on a history <br /> for wind direction in the area, which typically originate from the northwest. Air samples were <br /> collected simultaneously from each location over an eight-hour period during normal working <br /> hours and normal operating conditions. <br /> The asbestos pile location within the landfill and the sampling locations are illustrated in Figures <br /> 3-1 and 3-2. <br /> RlrB'W"Shaw&Mronrr>erl,k 1-1 <br />
