Asbestos monitoring was <br /> performed in accordance with the Forward Landfill Solid Waste Facility Permit No. 39- <br /> AA-0015. Asbestos monitoring was performed by Del-Tech Geotechnical Support <br /> Services (Del-Tech) on September 15, 2014, in accordance with the Air Monitoring Plan <br /> provided in Appendix A. Laboratory analyses were performed by Asbestos TEM <br /> Laboratories, Inc. (ATEML) of Berkeley, California, a state certified laboratory. The <br /> analytical laboratory report and field data is presented in Appendix B. <br /> SAMPLING PROCEDURES <br /> As shown on Figure 1, five sampling locations were established near the asbestos <br /> operations area. Four sampling stations were located predominately downwind and <br /> one sampling station (Sample Station A) was located predominately upwind from the <br /> asbestos disposal area. Upwind and downwind locations were chosen based on <br /> historical and site observations. Air samples were collected simultaneously from each <br /> location over an eight-hour period during normal working hours and typical landfill <br /> operating conditions. <br /> Each sampling station consisted of a sampling pump (with a built-in rotameter), filter <br /> cassette, connective tubing, and mounting materials. Each filter used for air monitoring <br /> consisted of a 25 millimeter diameter encased conductive cassette with a 0.45-micron <br /> mixed cellulose ester membrane. The pumps used for sampling were GilAir-5 constant <br /> flow air sampling pumps with a flow capacity of 1 to 5 liters per minute (L/min). The <br /> built-in rotameters on the GilAir-5 pumps were pre-tested (calibrated) using a dry <br /> reference standard flow meter. <br /> 11415 W.Bernardo Court,Suite 200,San Diego,California • T 858.451.1136 • F 858.451.1087 • www.geo-logic.com <br />
