ATTACHMENT B <br /> FIELD AND LABORATORY PROCEDURES <br /> Health and Safety <br /> Prior to performing field work at the site, SECOR will prepare a Site-Specific Health. and <br /> Safety Plan required by the Occupational Health and Safety Administration (OSHA) <br /> Standard"Hazardous Waste Operations and Emergency Response".guidelines (29 CFR <br /> 1910.120) and by California Occupational Health and Safety Administration (Cal-OSHA) <br /> "Hazardous Waste Operations and Emergency Response" guidelines (CCR Title 8; Section <br /> 5192). The Site-Specific Health and Safety Plan will be reviewed by field staff and <br /> contractors before beginning field operations at the site. <br /> CPT Borings and Soil and Groundwater Sampling <br /> The CPT soil borings will be advanced using a direct push cone penetrometer testing (CPT) <br /> rig to log soil stratigraphy. Immediately adjacent to each CPT borehole, a second direct-push <br /> borehole will be advanced to collect discrete soil and groundwater samples. Soil samples ., <br /> will be collected using an Envirocore sampler, or similar technology. Soil samples will be <br /> retained in plastic sleeves and capped with Teflon squares and plastic end caps. <br /> Groundwater samples will be collected using a hydropunch, or similar technology, by <br /> lowering a stainless steel or Teflon bailer into accumulated groundwater in the borehole, then <br /> retrieving and transferring the water into laboratory supplied containers. The soil and <br /> groundwater sample containers will be placed on ice for transport to the laboratory <br /> accompanied by chain-of-custody documentation. Down-hole boring and sampling <br /> equipment will be steam-cleaned prior to and following the completion of each soil boring. <br /> Down-hole sampling equipment will be washed in a tri-sodium phosphate or Alconox rm <br /> solution between samples. <br /> Laboratory Procedures <br /> Groundwater samples collected will be analyzed for the presence of total petroleum <br /> hydrocarbons as diesel (TPHd) and total petroleum hydrocarbons as gasoline (TPHg) by EPA <br />
