12. Air Monitoring <br />AIR MONITORING <br />Continual air monitoring shall be performed to evaluate air emissions at the site. The SHSO <br />shall determine if industrial hygiene or additional sampling is needed to assess health and safety <br />at the site. <br />Concentrations of volatile organic compounds (VOCs) will be screened using an FID or a PID <br />equipped with an 11.7 eV bulb. A GMI 422 Gas Surveyor Instrument will be used to measure <br />hydrogen sulfide, methane, oxygen, and carbon monoxide. Dust will be monitored visually. <br />Air monitoring to determine the presence of combustible gas shall be performed with a <br />In addition, a windsock shall be used to identify wind direction. <br />RADIATION MONITORING <br />Radiation monitoring will occur on two levels: personnel monitoring using individual digital <br />alarm dosimeters and survey monitoring using portable survey meter. <br />Personal Radiation Monitoring <br />At the beginning of each workday, each field worker will don a personal radiation dosimeter. <br />Dosimeters shall be digital, "pager -type" dosimeters, such as the model PD -I Oi personal <br />dosimeter manufactured by Science Applications International Corporation (SAIC), of San <br />Diego, California. The dosimeters must be capable of detecting gamma radiation to the nearest 1 <br />microroentgen per hour (µR/hr). <br />At the start of the project, all personnel shall ensure their dosimeters are provided to the Site <br />Health and Safety Officer (SHSO), who will maintain personal radiation exposure records. At <br />the beginning of each working day, the designated Site Health and Safety Officer will "zero -out" <br />each dosimeter, and assign one to each person working in the landfill excavation area. At the <br />end of each day, personal dosimeters will be returned to the SHSO who will record the daily <br />exposure for site worker. The SHSO shall maintain a project log of each project member, and <br />shall ensure that individuals receive no more than 100 mR for the project. In the event that the <br />SHSO is not on site during a particular day, radiation dose monitoring will be performed by <br />BAS/GLA. <br />Radiation Surveying <br />Radiation surveying will be conducted using approved and calibrated survey equipment capable <br />of measuring gamma radiation emissions of at least 1 µR. Approved radiation survey equipment <br />includes the Digital Ratemeter manufactured by Ludlum Instruments and the M14V Surveyor <br />2000 manufactured by Bicron/Saint Gobain. Other equipment may be approved after a <br />consultation with the CIWMB's Closed, Illegal, Abandoned Site representative. These <br />instruments must be calibrated at least once each year by the manufacturer or at a designated <br />service center to ensure field accuracy. <br />Santa Fe Road Disposal Site — Health & Safety Plan 30 October 2002 <br />
